Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a steam/water separation device for a water jet room.

Since the woven fabric woven in the water jet loom contains a large amount of water, it is preferable to remove this water on the machine for ease of handling in the subsequent process.

For this purpose, a water absorption pipe connected to a suction fan or the like is usually installed close to and facing the fabric surface at an appropriate position while the fabric moves from the front of the fabric to the cross roller, and the suction force of the fan causes the fabric to It seems to absorb moisture.
The water suction pipe is conveyed to, for example, an air-water separation chamber, and the water from which air has been separated in the separation chamber flows down into the lower water storage chamber through the water filling port at the bottom. By the way, the system consisting of the water suction conduit, the separation chamber, and the water storage chamber as described above is under negative pressure as a whole, that is, lower than atmospheric pressure, due to the water absorption action by the fan.

The separated water must ultimately be discharged from this negative pressure into the external atmospheric pressure system, but because there is a pressure difference inside and outside, special measures are required for this discharge. As a device for this purpose, for example, there is a device using a balance type float valve, as proposed in Utility Model Application Publication No. 61-12416.

However, such a balance-type float valve mechanism lacks operational reliability and is prone to failure, as is often experienced in household hand wash basins, and its industrial use is questionable. There are also other types that use a special drain valve that is linked to the operation of the loom, such as the one devised in Utility Model Publication No. 50-32616, but since the loom does not stop and water cannot be drained, it is used as a tank. It is necessary to use a large-capacity device, which has the disadvantage of increasing the size of the device.

Furthermore, there are systems that use a special electric circuit, such as the invention of Tokukan Sho 49-102965, but this is not only structurally complex, but also requires special power for drainage. There are drawbacks.

The object of the present invention is to provide a steam/water separation device for a water jet loom, which has high operational reliability, is simple in structure, and does not require special power consumption for its operation. , to provide.

This application includes two inventions, both of which have a water storage chamber installed at the bottom of the air-water separation chamber through a water-filling port, which further allows outside air to pass through through fine ventilation holes. A pillar-shaped guide is erected inside the drain, and a drain port with a check valve is formed at the bottom, and the float is shielded from the guide.

In the first aspect of the invention, a valve body is further provided at the upper end of the guide, facing the drip opening and connected to the float by a connecting body with play.

In the second invention, the float has a valve head facing the full water opening, and the bottom thereof is formed of a magnet or a magnetic material, and a magnet is fixed on the bottom plate of the water storage chamber opposite to this. There is. DESCRIPTION OF THE PREFERRED EMBODIMENTS The steam/water separation apparatus of the present invention will be described in more detail below with reference to embodiments shown in the accompanying drawings.

An embodiment of the steam/water separation device according to the first invention is shown in FIG. 1A.
- Shown in C.

A water storage chamber 6 is provided at the bottom of the steam/water separation chamber 2 through a water filling port 3, and a check valve 7 that opens only outward is attached to a drain port 8 formed at the bottom of the storage chamber 6. has been done. Further, a cylindrical guide 61 is erected approximately at the center of the bottom wall of the water storage chamber 6, and an umbrella-shaped valve body 62 is suspended at the top of the guide 61.
The outer surface of the valve body 62 is preferably covered with an elastic material such as rubber in order to ensure the valve closing effect. The float 63 is loosely connected to the guide 611. The valve body 62 and the float 63 are connected to each other with play, for example, a string 6.
Connected by 4 etc. Incidentally, a vent hole 66 is transparently formed in the peripheral wall near the ceiling of the water storage chamber 6. Figure 1A
In this state, both the separation chamber 2 and the water storage chamber 6 are in a negative pressure state (a pressure state lower than atmospheric pressure) due to the suction action of a suction fan etc. The check valve 7 is closed by the pressure difference (which is insignificant compared to the suction).

Further, the valve body 62 is placed on the upper end of the guide 61, and the float 63 is maintained in the state shown in the figure by gravity, and the water separated in the separation chamber 2 drips through the water filling port 3 and flows into the water storage chamber 6. It accumulates. As the separation of air and water in the separation chamber 2 progresses, the water level in the water storage stem 6 gradually rises, and finally the float 63
The buoyant force acting on the float overcomes the gravity, and as a result, the float 63 rises as the water level rises, and eventually its upper surface touches the valve body 62.
touch the bottom edge of the This state is shown in FIG. 1B. When this condition progresses further and the amount of accumulated water increases, the valve body 62
3, and finally ends up blocking the full water opening 3.

This state is shown in FIG. 1C. When the valve body 62 closes the water filling port 3, the suction action from the separation chamber 2 side no longer acts on the water storage chamber 6.

On the other hand, since the water storage chamber 6 is connected to outside air through the ventilation hole 66, under conditions where the above-mentioned suction effect does not work, the water storage chamber 6
The difference in pressure between the inside and outside of the area disappears. Therefore, the check valve 7 is pushed open by the water pressure of the dripping water accumulated in the room, and the water in the room is discharged through the drain port 8, and the water level is lowered. As the water level goes down, F.

The port 63 gradually descends due to the action of gravity. but,
Since the water filling port 3 is closed by the valve body 62 as described above, communication between the separation chamber 2 and the outside air via the ventilation hole 66 and the diving chamber 6 is blocked. Therefore, the degree of negative pressure in the separation chamber 2 increases, and on the other hand, since the interior of the water storage chamber 6 is under atmospheric pressure conditions as described above, the valve body 62 is no longer pushed up by the float 63 due to the pressure difference. Also, just like that) full water mouth 3
It is sucked into the air and kept in a closed state. and,
As the water level decreases, the lower surface of the valve body 62 and the upper surface of the float 63 gradually separate, and eventually the string 64 becomes tense. The water level in the water storage chamber 6 continues to fall until the difference between the buoyant force acting on the float 63 and gravity becomes equal to the difference between the suction force acting on the valve body 62 and gravity.

When the former difference exceeds the latter difference, the valve body 62 descends to the upper end of the guide 61 and opens the full water port 3. Therefore, the suction effect from the separation chamber 2 comes to work on the water storage chamber 6 again.
The pressure difference between the two disappears, and the check valve 7 closes.

At this point, the float 63 also loses the balance of forces acting on it and returns to the state shown in FIG. 1A. As is clear from the above explanation, drainage is carried out from the top water level by string, etc.
4 becomes tense until the water level further drops and the valve body 62 opens the full water port 3.

The length of this string etc. 64 is appropriately determined in accordance with practical conditions, taking into consideration the specifications of the float 63, the capacity of the water storage chamber 6, the drainage cycle, etc. An embodiment of the steam/water separation apparatus according to the second invention is shown in FIGS. 2A and 2B and will be described below.

The water filling port 3, vent hole 66, drain port 8, check valve 7, etc. are the same as in the first invention. A cylindrical guide 61' is installed approximately at the center of the bottom wall of the water storage chamber 6.
It has a float 63' having a valve head 62' on the top. Valve amount 62 to ensure valve occlusion effect
' is preferably made of an elastic material such as rubber. A magnet 67 is fixed at an appropriate position on the bottom wall of the water storage chamber 6.
At least the portion of the bottom surface of the float 63' facing the magnet 67 is formed of a magnet or a magnetic material. The other structure of the water storage chamber 6 is the same as that described above. In the state shown in FIG. 2A, both the separation chamber 2 and the water storage chamber 6 are in a negative pressure state due to the suction action of a suction fan or the like, and the check valve 7 is closed due to atmospheric pressure or the like.

In addition, the float 63' with a valve head is maintained in the state shown in the figure by the magnetic attraction force of the magnet 67 and the gravity acting on itself, and the water separated in the separation chamber 2 drips through the water fill port 3 and becomes a reservoir. It accumulates in room 6. As the separation progresses in the separation chamber 2, the water level in the reservoir chamber 6 also rises, and the buoyant force acting on the float 63' due to this accumulated water gradually increases. As this condition progresses further and the amount of accumulated water increases, the buoyancy force described above will exceed the sum of the magnetic attraction force and gravity acting on the float 63', and as the float 63' floats up, the magnetic attraction force will rapidly decrease. centre.

The balance of the force acting on the float 63' is lost and the float 63'
The water rapidly rises to the top of the water storage chamber 6 and closes the water filling port 3, resulting in the state shown in FIG. 2B. Therefore, in the next stage, as in the case of the previous example, there is no difference in pressure between the inside of the water storage chamber 6 and the outside air, and the water pressure of the collected water pushes open the check valve 7 and drains the water. Incidentally, in this case as well, the problem of the amount of discharge per time arises as in the case of the first invention.

In the first invention, this problem was solved by making the string connecting the valve body and the float loose, but in the second invention, the valve body and the float are integrated, so to speak. It lacks an element equivalent to etc. Therefore, if it is desired to obtain a considerable amount of wastewater per discharge, a magnet 68 is installed on the ceiling of the water storage chamber 6 as shown in FIG. 69 is installed and the amount of drainage is increased by the magnetic attraction between both magnets.
That is, the upward force acting on the float 63' (the sum of the attraction force from the separation chamber 2, the magnetic attraction force, and the buoyancy force) is the sum of the downward force (the sum of the gravity acting on the float 63' itself and the magnetic attraction force by the magnet 67). Drainage can continue for a longer period of time. Since the strength of the magnetic attraction by the upper magnets 68 and 69 has the same meaning as the length (degree of slack) of the string in the first invention, it can be determined as appropriate in consideration of the practical conditions as well. . According to this invention, since the movable parts are in a floating relationship with each other, there is no resistance to movement, and therefore operational reliability is high.

In addition, regardless of the operating state of the loom, the presence or absence of drainage is determined by the balance between the gravity of the float and the buoyant force acting on it, so there is no need to increase the size of the water storage chamber. In addition, it is structurally very simple because it only uses a float and a guide or a valve body in addition to these. In addition, pressure difference, gravity,
Since the balance between buoyancy, water pressure, and magnetic force is used to provide movement to each part, there is no need to combine external power for this purpose.
