Description

  The present invention relates to a core up-down type oil combustor, and an object thereof is to prevent pressure fluctuations in an oil tank caused by lowering the core during a fire extinguishing operation from affecting combustion.

  The core up-down type oil combustor is composed of a core outer cylinder attached to the upper surface of the oil tank and a core inner cylinder erected from the bottom surface of the oil tank, and the core inner cylinder constituting the core accommodating cylinder A core is held up and down in the gap between the core and the outer cylinder, and a burner is mounted on the upper part of the core accommodating cylinder. The lead accommodating cylinder is provided with a lead raising / lowering device for moving the lead up and down. When a lead raising / lowering operation knob for driving the lead raising / lowering device is operated, the lead is raised and the tip is positioned in the burner. When the lead is ignited by an ignition device (not shown), the kerosene sucked up by the lead from the oil tank is vaporized and burned by the combustion heat at the upper end of the lead, and the fuel and air evaporated in the upper burner are Mix and give the best combustion.

  Also, the core lowers by the core lifting device, the most part of the core is drawn into the oil tank, and the upper end of the core is separated from the burner, thereby reducing the combustion heat and shutting off the supply of combustion air and extinguishing the fire. To do. When the wick is lowered into the oil tank to extinguish the fire, it is necessary to expel the air of the lowered wick volume out of the oil tank, and the air in this oil tank removes the oil gas from the gap of the wick housing cylinder to the upper burner. It blows out as contained air. At this time, the flame still remains in the burner, and the air containing the oil and gas may cause a trouble that is ignited by this flame and blows out the fire.

  Therefore, a degassing mechanism having a degassing passage is attached to the upper surface of the oil tank, and when the internal pressure of the oil tank is increased, the oil degassing passage provided in the degassing mechanism replaces the oil from the degassing passage provided in the degassing mechanism. Some tanks allow air in the tank to escape. At this time, the cylinder part that extends below the degassing mechanism and is mounted over the oil level in the oil tank prevents the splash of oil generated in the oil tank from splashing outside due to the impact when the core is lowered. There is work.

JP 2003-139383 A

  The degassing passage that opens and closes by the degassing mechanism has a large internal pressure increase in the oil tank when the core is lowered, depending on the model with a large core lowering impact. Even if the amount of air that escapes from the tank is not sufficient and a degassing mechanism is provided, more air in the oil tank containing petroleum gas is blown from the core housing cylinder to the upper burner, causing a problem of standing flames. There are cases where it cannot be resolved. For this reason, if an attempt is made to enlarge the gas vent passage that is opened and closed by the gas vent mechanism, the valve for opening and closing the gas vent passage becomes larger and heavier as the entire gas vent mechanism becomes larger, and the gas in the oil tank when the core is lowered. The valve cannot be pushed open reliably due to the pressure increase.

The present invention is a gas venting structure of a core vertical oil combustor capable of creating a large opening area even if the gas venting mechanism is small, and the core inner cylinder 2a of the core accommodating cylinder 2 is formed from the bottom surface of the oil tank 1. A wick 3 is disposed outside the wick inner cylinder 2 a, and a gas venting mechanism A is attached to the opening 4 provided on the upper surface of the oil tank 1. The gas venting mechanism A is located outside the oil tank 1. The valve mechanism 5 is located at a position that opens when the internal pressure of the oil tank 1 rises, and the cylindrical portion 6 extends from the valve mechanism 5 to the inside of the oil tank 1, and the internal space in the oil tank 1 is gas. In the core vertical oil combustor which communicates with the outside of the oil tank 1 through the valve mechanism 5 from the inside of the cylinder portion 6 of the extraction mechanism A, the valve mechanism 5 is above the valve seat formed by the inner edge of the valve hole 5a. the valve 7 up and down independently placed, a cylindrical guard 8 you positioned outside of the valve 7, the cylinder Constituted by a valve cover 9 mounted on the guard 8, and the cylindrical guard 8a forms a venting slit 8a arranged at equal intervals in the entire circumference, an opening is formed in the upper surface in the valve cover 9 to form a valve cover slit 9b, the valve 7 is formed below the convex hemispherical, gas oil tank 1 at the core drop flows toward the valve hole 5a, push the separate the valve 7, the tubular increased to the valve 7 the valve cover 9 air in Jo guard 8 is missing from the valve cover slits 9b and venting slits 8a, together with the gas escapes from the venting slits 8a of the tubular guard 8, independently The valve 7 that moves up and down is a hemispherical convex surface that is placed on the valve seat of the valve hole 5a to close the gas vent passage.

Since the valve 7 that moves up and down independently in this way is a hemispherical convex surface and rests on the valve seat of the valve hole 5a to block the gas vent passage, when the pushed-up valve 7 descends and closes the valve hole 5a, the valve 7 The valve hole 5a could be closed by the hemispherical convex surface regardless of the inclination even if the angle was inclined.

  Further, a weight 10 is attached to the center of the valve 7 that is guided by the cylindrical guard 8 and moves up and down independently from the valve seat of the valve hole 5a. Since the valve 7 is pressed onto the valve seat formed by the inner edge of the hole 5a, when the valve 7 that has been lifted is lowered, the lowering position of the valve 7 is regulated by the weight 10, whereby the inclination of the valve 7 can be prevented. It was.

The valve mechanism 5 is a cylindrical guard provided with a valve 7 that moves up and down independently on a valve seat formed by the inner edge of the valve hole 5a, and a gas vent slit 8a located outside the valve 7. 8 and a valve cover 9 mounted on the cylindrical guard 8, and the valve mechanism 5 is mounted on a valve seat formed by the inner edge of the valve hole 5a, and the valve 7 is moved up and down independently. a cylindrical guard 8 you positioned outside of the valve 7, constituted by a valve cover 9 attached to the top of the tubular guard 8 and the cylindrical guard 8a degassed arranged at equal intervals in the entire circumference A slit 8a is formed, the valve cover 9 is formed with a valve cover slit 9b that forms an opening on the upper surface, and a shaft 11 that hangs down from the center of the valve cover 9 toward the valve hole 5a. A hole 7a through which the shaft 11 is inserted is provided, and the gas in the oil tank 1 flows through the valve hole 5 when the core is lowered. Flows towards, pushes up the valve 7 independent, with air in the tubular guard 8 rises to the valve 7 the valve cover 9 exits from the valve cover slits 9b and degassing slit 8a, the valve 7 is regulated by the shaft 11 and moves up and down independently. Therefore, when the valve 7 moves up and down, the valve 7 does not tilt, and the valve hole 5a can be reliably closed.

Also, with the valve mechanism 5 is a valve 7 which vertically independently placed on the valve seat formed at the inner edge of the valve hole 5a, a cylindrical guard 8 you positioned outside of the valve 7, the tubular The valve guard 9 is mounted on the guard 8, and the tubular guard 8a is formed with gas vent slits 8a arranged at equal intervals on the entire circumference. A rail-shaped recess is formed inside the tubular guard 8. 8b is formed, and an engagement portion 7b that fits into the rail-shaped recess 8b is provided on the outer periphery of the valve 7, and the valve cover 9 is formed with a valve cover slit 9b that forms an opening on the upper surface. The gas in the tank 1 flows toward the valve hole 5a, pushes up the independent valve 7, and the air in the cylindrical guard 8 escapes from the gas vent slit 8a and the valve cover slit 9b. with increases to cover 9, the valve 7 is engaging portion 7b Galle Since your own vertical movement is restricted in Le recess 8b, the valve 7 is no longer lean when the valve 7 moves up and down, it was possible to close reliably valve hole 5a.

  In the present invention, even if the gas venting mechanism is small, a large opening area can be created in the gas venting passage. If the valve hole 5a is small, the core 3 may be lowered quickly depending on the model. The internal pressure rise in the oil tank 1 during the lowering is large, and there is a case where a flame is generated from the upper part of the burner. However, a valve hole 5a is formed inside the cylindrical guard 8 and the valve cover 9 constituting the valve mechanism 5. Since the valve 7 which is mounted on the valve seat formed at the inner edge of the valve and moves up and down independently is mounted, the valve hole 5a is greatly opened when the valve 7 is raised, and the oil tank 1 is also opened when the core 3 is quickly lowered. It was possible to release the gas immediately to the outside and to suppress the standing flame from the burner.

  Further, the valve 7 is formed in a hemispherical shape with a convex downward, and the independently rising and lowering valve 7 is mounted on a valve seat formed on the inner edge of the valve hole 5a with a hemispherical convex surface to constitute a gas vent passage Therefore, when the valve 7 is lowered after the valve 7 is pushed up to close the valve hole 5a, the hemispherical convex surface is used regardless of the inclination. Since the valve hole 5a is closed, it is not left open, and the fire does not disappear when extinguishing.

  A weight 10 is attached to the central portion of the valve 7 that is guided by the cylindrical guard 8 and moves up and down independently from the valve seat formed by the inner edge of the valve hole 5a. 7 has a structure pressed against the valve seat of the valve hole 5a. Therefore, when the valve 7 descends after the valve 7 is pushed up, the valve 7 is pulled by the weight 10 and the valve 7 remains tilted. It does not rest on the seat, the valve hole 5a is reliably closed at the correct position, the valve hole 5a does not remain open, and the fire does not disappear when the fire is extinguished.

  Further, a shaft 11 that hangs down from the center portion of the valve cover 9 toward the valve hole 5a is formed. The valve 7 is provided with a hole 7a through which the shaft 11 is inserted, and when the core 3 is lowered, the valve 7 is attached to the shaft 11. Since it is configured to move up and down independently by being regulated, the valve hole 5a can be reliably closed by the valve 7 without tilting the valve 7, and the valve hole 5a does not remain open, The fire is no longer extinguished when it is extinguished.

  Further, a rail-shaped recess 8b is formed inside the cylindrical guard 8, and an engaging portion 7b that fits into the rail-shaped recess 8b is provided on the outer periphery of the valve 7, and the engaging portion 7b of the valve 7 is a rail. Since it is regulated by the concave portion 8b and moves up and down independently, even with this structure, the valve hole 5a can be reliably closed without the valve 7 tilting, and the valve hole 5a can remain tilted and open. The fire is no longer extinguished when the fire is extinguished. Further, since the shaft of the valve cover 9 as in the above embodiment is not required and the valve 7 does not need to be passed through the shaft of the valve cover, the structure is simple and the assembly of the gas venting mechanism is facilitated.

  Next, the configuration will be described with reference to the drawings showing an embodiment. 1 is an oil tank of an oil combustor, 3 is a core of an oil combustor with its lower end extended into the oil of the oil tank 1, and 2 is for housing the core 3. The core housing cylinder 2a is a core inner cylinder erected from the bottom surface of the oil tank 1, 2b is a core outer cylinder continuous from the top plate of the oil tank 1, and the core housing cylinder 2 is connected to the core inner cylinder 2a and the outer core. The cylinder 2b is configured, and the core 3 is mounted in the gap. A core up / down knob 12 is attached from the outside of the core housing cylinder 2 toward the core 3, and 13 is a burner provided at the upper part of the core housing cylinder 2. 3, the core 3 protrudes from the core housing cylinder 2 to the lower part of the burner 13 and ignites the core 3 by an ignition device (not shown). The fuel in the oil tank 1 is burned in the burner 13 while being sucked up by the core 3. .

  Reference numeral 4 denotes an opening provided in the upper surface plate of the oil tank 1, A denotes a gas venting mechanism to be attached to the opening 4, 5 denotes a valve mechanism body constituting an outer portion of the oil tank 1 of the gas venting mechanism A, and 6 denotes this valve mechanism. It is a cylindrical portion that extends downward from the body 5 and is configured by an inner portion of the oil tank 1 of the degassing mechanism A. The cylindrical portion 6 extends toward the oil surface in the oil tank 1, and the cylindrical portion 6 The tip of the nozzle forms a small gap with the oil surface when the core is lowered.

  5a is a valve hole formed between the valve mechanism body 5 constituting the gas venting mechanism A and the cylinder part 6, and 7 is a valve that is in close contact with the valve seat formed at the inner edge of the valve hole 5a to open and close the valve hole 5a. In normal times, the valve 7 closes the valve hole 5a, so that outside air does not enter the space in the oil tank 1. Although the internal pressure of the oil tank 1 rises when the core 3 is rapidly lowered and pulled down into the oil tank 1 by the core lifting device when the oil combustor is extinguished, the valve hole 5a and the valve 7 are provided with a gas vent mechanism A. A gas vent passage that escapes from the cylinder portion 6 through the valve mechanism 5 to the outside is configured. Even if the internal pressure of the oil tank 1 rises, this pressure is increased by the valve vent passage opened by moving the valve 7 upward. It can be pulled out, so that it cannot be pulled out to the burner 13 through the gap in which the core 3 of the core housing cylinder 2 is inserted.

  By mounting the gas venting mechanism A in this way, it was possible to prevent the standing flame generated in the burner 13 by blowing out air containing petroleum gas from the gap of the core housing cylinder 2 when the core 3 is lowered. When the degassing mechanism A is operated slowly with the core up / down knob 12 or the like, even if the gas venting mechanism A operates satisfactorily, the core up / down knob 12 is quickly rotated to shorten the fire extinguishing time, or the core lifting / lowering device is moved by spring force or the like. When driving, the internal pressure of the oil tank 1 rises rapidly, and the conventional venting mechanism A sometimes cannot prevent the standing flame phenomenon.

  The present invention proposes a gas venting mechanism A capable of quickly releasing the internal pressure of the oil tank 1, and 8 is a cylindrical shape provided around the outer periphery of the valve hole 5a at a portion of the valve mechanism 5 of the gas venting mechanism A. Guards 8a are gas vent slits formed at four equal intervals on the side wall of the cylindrical guard 8, and the valve 7 is disposed on the valve seat formed by the inner edge of the valve hole 5a in the cylindrical guard 8. The valve 7 is guided by the cylindrical guard 8 and mounted so that it can be moved up and down independently.

  Then, when the internal pressure of the oil tank 1 is increased by the fire extinguishing operation of the oil combustor, the valve that can be raised and lowered independently when the gas in the oil tank 1 escapes from the cylinder part 6 of the gas venting mechanism A through the valve mechanism body 5. 7 is smoothly pushed, the valve 7 is pushed up by the pressure of the gas in the oil tank 1, and the pressure in the oil tank 1 received by the valve 7 passes through the gas vent slit 8 a of the cylindrical guard 8. After that, I was able to escape to the outside. Even when fine oil droplets are mixed with this gas, the oil droplets are liquefied when they touch the inner surface of the cylindrical guard 8, so that the kerosene is less scattered outside the valve mechanism 5.

  9 is a retaining valve cover that is mounted on the cylindrical guard 8, 9 a is a valve cover fixing claw that fits into a recess provided outside the wall surface of the upper end of the cylindrical guard 8, and 9 b is the valve of the cylindrical guard 8. It is a valve cover slit that forms an opening on the upper surface of the cover 9, and the concave portion of the tubular guard 8 and the valve cover fixing claw 9 a of the valve cover 9 are fitted and fixed to the valve cover 9. It is fixed so that it does not come off. For this reason, a valve cover 9 is fixed to the upper end of the cylindrical guard 8 in a state where the valve 7 is placed on the valve hole 5 a in the cylindrical guard 8. Even when the internal pressure is raised, the valve cover 9 can prevent the valve mechanism 5 from popping out. When the valve 7 moves upward due to an increase in the internal pressure of the oil tank 1, air in the cylindrical guard 8 above the valve 7 escapes not only from the gas vent slit 8a but also from the valve cover slit 9b. 7 can quickly move up to the vicinity of the valve cover 9.

  In the embodiment shown in FIG. 3, the valve 7 is formed in a hemispherical shape with a convex downward, and the independently rising and lowering valve 7 is placed on the valve seat of the valve hole 5a with a hemispherical convex surface. Therefore, even if the valve 7 is inclined and rides on the valve seat, the hemispherical convex surface causes the valve regardless of the inclination. The hole 5a could be closed.

  In the embodiment shown in FIG. 4, reference numeral 10 denotes a weight attached from the vicinity of the central portion of the valve 7 so as to extend downward from the valve seat of the valve hole 5 a, and the valve pushed up by an increase in the internal pressure of the oil tank 1. Since the center of gravity of the valve 7 is positioned below the valve seat of the valve hole 5a when the valve 7 is lowered, the weight 7 causes the valve 7 to rest on the valve seat formed by the inner edge of the valve hole 5a. Therefore, the valve 7 was not stopped while one side of the valve 7 was caught by the cylindrical guard 8 and tilted, and the valve 7 could be reliably sealed without tilting.

  In the embodiment shown in FIG. 5, 11 is a shaft that hangs downward from the valve hole 5a from the central portion of the valve cover 9, and 7a is provided so that the shaft 11 is inserted through the central portion of the disc-shaped valve 7. The valve 7 is configured to move up and down independently by being regulated by the shaft 11 between the valve seat portion on the periphery of the valve hole 5a and the valve cover 9. For this reason, when the internal pressure of the oil tank 1 rises when the core 3 is lowered, the valve 7 moves up along the shaft 11, and when the internal pressure of the oil tank 1 falls and the valve 7 falls, the valve 7 Even if the tubular guard 8 is lowered along the shaft 11 without touching, and the valve 7 is tilted in the valve mechanism 5, it can be placed at an accurate position above the valve hole 5 a and the valve hole 5 a can be reliably closed. Therefore, when the fire is extinguished, there is no trouble that air is supplied into the oil tank 1 and the fire of the burner 13 cannot be extinguished.

  Reference numeral 9c denotes a raised portion formed from the center of the valve cover 9 toward the valve 7. The shaft 11 is provided downward from the raised portion 9c, and the mounting strength between the valve cover 9 and the shaft 11 is provided. Since the valve 7 that has moved up does not adhere to the valve cover 9 due to the raised portion 9c, the valve 7 is attached to the valve cover 9 even when the oil droplets adhere to the valve 7 and become wet. Troubles such as sticking and leaving no longer occur.

Further, in the embodiment shown in FIG. 6, 8b is a rail-shaped recess formed on the inner wall surface of the cylindrical guard 8, and 7b is an engagement provided on the outer periphery of the valve 7 so as to fit the rail-shaped recess 8b. The rail-shaped concave portion 8b is formed in a vertical direction, and the engaging portion 7b of the valve 7 is fitted into the rail-shaped concave portion 8b, and the engaging portion 7b of the valve 7 is rail-shaped. It is possible to eliminate the trouble that the valve 7 that is moved up and down independently in the state restricted by the recess 8b, and that the descending valve 7 is caught on the side wall of the cylindrical guard 8 and the valve hole 5a is left open can be solved. The hole 5a could be closed. Further, since the shaft 11 of the valve cover 9 is not required as in the embodiment of FIG. 5 and the valve 7 does not need to be passed through the shaft 11, the structure is simple and the assembly of the gas venting mechanism is facilitated.

  Further, when the valve 7 moves up due to an increase in the internal pressure of the oil tank 1, the pressure is related to the center point of the valve 7, so that it does not tilt greatly, and this fitting is also achieved in the short engaging portion 7b and the shallow rail-shaped concave portion 8b. Will not come off. However, depending on the shape of the cylinder portion 6 of the gas venting mechanism A, the internal pressure of the oil tank 1 may be strongly related to a position away from the center of the valve 7. And the rail-shaped recess 8b will be disengaged. In the engaging portion 7b of the embodiment shown in FIG. 6, since the end is directed upward and along the rail-shaped recess 8b, when there are two engaging portions 7b as in the embodiment, the other When the valve 7 is inclined so that the direction of the engaging portion 7b is increased, a force for moving the valve 7 in the direction of the other engaging portion 7b increased by the engaging portion 7b directed upward is applied. The engagement between the inclined and raised engaging portion 7b and the rail-shaped concave portion 8b is difficult to come off, and the valve 7 is always connected to the valve hole 5a by the action of the engaging portion 7b of the valve 7 and the rail-shaped concave portion 8b. It was able to be correctly placed on the valve seat on the periphery.

  In the valve mechanism body 5 of the degassing mechanism A shown in the drawings as an embodiment, 5b is a plurality of convex portions provided to prevent the valve 7 from sticking to the portion facing the valve 7 at the upper end of the valve hole 5a. When the valve 7 is opened through the valve hole 5a and the gas flowing out is mixed with oil droplets, the valve 7 may get wet and be in close contact with the upper end surface of the valve hole 5a. The valve 7 may not open unless a large pressure that overcomes the surface tension of the valve 7 is applied. However, by providing the convex portion 5b, the valve 7 does not come into close contact with the upper end surface of the valve hole 5a. Began to open. Also, there are a plurality of convex portions 5b, and even if oil adheres to the convex portions 5b, there is a difference in the amount of adhesion for each convex portion 5b, so the valve 7 starts from the portion where a small amount of oil has adhered. After being lifted, the valve 7 can move up. In addition, by reducing the height of the convex portion 5b, there is no problem in the combustion state of the oil combustor because a close contact state is substantially produced even if there is a minute gap and there is almost no air circulation. .

  In the cylinder part 6 of the degassing mechanism A shown in FIG. 2 which is an embodiment, 6a is a movable piece formed by a part of the wall of the cylinder part 6 other than the side facing the core 3, and 6b is a movable piece 6a. In order to make it possible, the cylindrical portion 6 is a vertical slit which is cut to the base, and the movable piece 6a cannot move the cylindrical portion 6 on the side facing the core 3 by the vertical slit 6b, but only the movable piece 6a. Can move. 6c is an engagement protrusion provided on the movable piece 6a. When the gas venting mechanism A is attached to the opening 4 of the oil tank 1, the engagement protrusion 6c of the movable piece 6a is pushed and deformed inward. However, when the gas venting mechanism A is pushed into the opening 4 and the engagement protrusion 6 c reaches the end of the opening 4 inside the oil tank 1, the deformed movable piece 6 a returns, and the engagement protrusion 6 c becomes the end of the opening 4. Are engaged to prevent the gas venting mechanism A from coming off.

  By the way, the core 3 is arranged outside the core inner cylinder 2a constituting the core housing cylinder 2, and the splash of oil generated when the core is lowered scatters in the oil tank 1 from the vicinity of the core 3, but faces the core 3. Since the vertical slit 6b is not formed in the cylindrical part 6 to be formed, this splash can be prevented by the cylindrical part 6 without the vertical slit 6b. Further, the increased pressure in the oil tank 1 escaping from the cylinder portion 6 through the valve mechanism 5 to the outside is not only the gap formed between the oil surface of the oil tank 1 and the lower end of the cylinder portion 6 but also this vertical slit. 6b can enter the cylindrical portion 6 so that a sufficient amount of gas can flow into the cylindrical portion 6 even if the gap formed between the oil level and the lower end of the cylindrical portion 6 is narrowed. As a result, splashing due to the undulation of the oil surface of the oil tank 1 is less likely to enter the cylindrical portion 6.

  Reference numeral 6d denotes a partition wall inside the movable piece 6a and the vertical slit 6b, and the movable piece 6a is a partition wall that connects the cylindrical portions 6 on both sides via a gap. The upper portion of the partition wall 6d is the outer periphery of the valve hole 5a. The lower end of the partition wall 6d is located at a position lower than the engaging projection 6c and above the lower end of the cylindrical portion 6 so as not to resist any movement of the movable piece 6a. It is configured. For this reason, even if the oil surface of the oil tank 1 undulates and the splash of oil tries to jump into the cylindrical portion 6 from the vertical slit 6b, the splash cannot directly go to the valve hole 5a. It adhered to the wall 6a and became oil droplets that dropped on the oil surface of the oil tank 1 and did not flow from the inside of the partition wall 6d toward the valve hole 5a.
