    The present invention relates to a technology for conveying granular materials and powdered materials, and particularly for granular fuels that can smoothly supply granular fuel, powdered fuel, and the like to combustion chambers such as boilers, stoves, and combustion furnaces.

(Points of interest)
Growing facilities such as greenhouses and other greenhouses for greenhouses and other greenhouses, such as temperature, humidity, shading, ventilation, irrigation, fertilization, pest prevention, etc., are indispensable throughout the year. It is not an exaggeration to say that proper room temperature control in winter is the most important issue, and it has been easier to transport and handle kerosene, light oil, heavy oil, etc. Many fossil fuels suitable for automatic combustion control have been used in recent years, but in recent years, from the viewpoint of consideration for the natural environment and economic efficiency, it is possible to regenerate with the goal of using high power and moving away from fossil fuels. Although the use of energy has been encouraged and full-fledged use of wood pellets made from recycled thinned wood and wooden building waste has been sought and put into practical use, wood pellets are granular. Present Stabilization and automatic control of the fuel supply in order that there was a technical problem that it is difficult.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as represented by those proposed in the following Patent Documents 1 (1) to 1 (5), wood pellets obtained by compression-molding wood into cylindrical small pieces are burned on an axial flow screw conveyor. Clogging such as a combustion device dedicated to wood pellets, which can be automatically supplied to the chamber, and granular materials and high-viscosity liquid materials as seen in Patent Documents 1 (6) to 1 (9) In addition to a non-axial screw conveyor or a pump having a spiral type power shaft that can be smoothly conveyed, a granular material from a hopper as shown in Patent Document 1 (10) to 1 (12) A plurality of concave portions for storing granular materials are formed on the peripheral wall surface of the rotor that receives the supply of the powder, and a predetermined amount of granular materials or the like is temporarily placed in the concave portions that are in an upward posture with the rotation of the rotor. Stow and rotor With a rotation, a predetermined amount of granular material can be dropped and supplied from a concave portion that is in a downward posture, or a sprinkling port partially around the screw conveyor as in Patent Document 1 (13) A rotating cylindrical body having an opening is externally mounted, and a part of the granular material that is circulated and supplied in the axial direction by a screw conveyor is dropped and scattered from the rotating cylindrical body spout, and a rectangular shape is formed on a belt conveyor that flows in an orthogonal direction. Intermittent spraying technology for granular materials that can be sprayed can be seen.

However, the combustion devices dedicated to wood pellets as shown in the former Patent Documents 1 (1) to 1 (5) are all shafts, so only wood pellets that are compression-molded to the same size and shape are used. It is effective to a certain extent for transportation and supply, but other wood chips containing bark and twig pieces that are not fixed in shape, and rice husk mixed with powder and grains containing shell pieces and branch pieces are used as fuel. As a result, there is a drawback that the axial flow type screw conveyor may be clogged and the fuel supply may be stopped. Since there is a great concern that if the flame enters the chamber, the base end will easily spread to the side and may cause a fire. (6) to 1 (9) Axis-type screw conveyors, which are concentrically arranged in a cylinder, are built into a combustion device, and trials are conducted to see if it is possible to prevent clogging of particulate fuel. However, in particular, the shaftless screw conveyor base end is clogged in the vicinity of the granular fuel introduction part of the wrinkle, revealing the problem that smooth conveyance cannot be performed as it is. Not only the screw conveyor but also the non-axis type screw conveyor cannot eliminate the concern that the combustion chamber may easily spread to the base due to the intrusion of the flame, and Patent Document 1 (10) to 1 (12) where the outer peripheral wall of the rotor is formed with a recess to enable the quantitative and intermittent supply of powder and particulate matter, even when the rotational drive source is stopped due to a power failure or the like. Although it is possible to prevent the spread of the fuel into the granular fuel upstream of the rotor, the rotor is tightly accommodated in the casing, so the woody material between the opening edge of each recess in the rotor and the inner peripheral wall of the casing There is a risk that the rotation will stop by biting granular fuel such as system pellets and wood chips, and the outer periphery of the screw conveyor of Patent Document 1 (13) with a rotating cylindrical body with an opening for sprinkling, There was a significant risk that the flame from the combustion chamber would spread through the rotor recesses and the rotating cylinder spout.

(Awareness of problems)
As mentioned above, all of the previously proposed combustion devices for various wood fuels have been developed using pre-made wood-based pellets as dedicated fuel, so other wood chips, rice husks, etc. However, it has not been adopted in the combustion equipment dedicated to wood pellets, but has been used for the transportation of granular materials and high-viscosity liquid substances. Combustion device incorporating a shaftless screw conveyor that has been put into practical use, when bark or branch pieces are mixed by long-term trial production and experimental operation by the applicant of the present application, and when conveying wood chips etc. whose shape is not constant, In particular, it has been found that there is a fatal defect that clogging is likely to occur between the guide pipe underneath the inner peripheral wall of the guide and the guide pipe proximal end near the guide introduction portion. In recent years, large-scale blackouts caused by various natural disasters such as earthquakes, typhoons, gusts, tornadoes, thunders, and human error, or carbon dioxide emissions after nuclear power plant accidents have been implemented. If the operating screw conveyor stops unexpectedly due to a long-term power outage for various reasons such as the planned power outage concerned, the tip of the screw conveyor will be removed from the hot combustion chamber. Even if you encounter such an emergency situation, you will notice that there is a major problem that the granular fuel exposed to the flame will easily ignite and the fuel tank will spread to the fire and cause a fire. It has come to a keen sense that there is a need for further improvements in a new configuration that can reliably prevent the flame from spreading in the direction.

(Object of invention)
Therefore, the present invention is not limited to wood pellets molded and processed into a fixed shape and size, but also uses various kinds of renewable energy that are easily available at low prices such as wood chips and rice husks that have a fixed shape and size. In addition to making it possible to automatically supply and discharge these particulate fuels smoothly, above all, in the event of an emergency such as a power outage, the tank for particulate fuel can reliably prevent the spread of fire from the combustion chamber to the trap. Judging whether it is possible to develop a new intergranular transfer technology for granular fuels, we quickly started developing and researching it, and as a result of repeating trial and error over many years and many trials and experiments, this time finally The present invention has succeeded in realizing an automatic fuel intermittent replenisher having a simple structure, and the configuration thereof will be described in detail below together with an embodiment representing the present invention shown in the drawings.

(Structure of the invention)
As will be clearly understood from the embodiments representing the present invention shown in the drawings, the automatic fuel replenisher of the present invention basically comprises the following configuration.
That is, one of the bottom surfaces in the fuel storage portion is provided with a fuel feed portion, and in the vicinity of the opposite side of the fuel feed portion, a replenishment tank that vertically penetrates a refill hole is provided at the bottom portion, A small gap is secured on the bottom surface of the horizontal surface of the replenishing tank facing the replenishing hole, and it protrudes in the centrifugal direction from the outer peripheral wall of the horizontal cylindrical idler cylinder with a predetermined diameter that is supported rotatably around the horizontal axis. 1 or more blades is not buffered in the fuel storage part bottom surface, to form a cylindrical intermittent blades provided so as to project only appropriate projection amount capable of preventing the biting of the particulate fuel is conveyed object In addition to the intergranular transfer device for granular fuel, an output shaft of a replenishing rotary drive source is connected to at least one shaft end of the cylindrical intercostal blade, and between the cylindrical interim blade blade and the replenishing hole. When the left and right guide ridges protrude across the bottom of the replenishment tank In a fuel blocking barrier ribs formed on the right and left guide convex or refill the tank, the tank bottom a top surface, a configuration in which those obtained by forming a Sekiguchi fuel enclosed in the right and left guide projections and the partition lower edge It is an automatic fuel replenishment machine that is the gist of it.

In the automatic fuel intermittent replenisher composed of this basic structure, if expressed in a different manner, one of the bottom surfaces in the fuel accommodating portion is provided with a fuel feeding portion, which is opposite to the fuel feeding portion. There is a replenishment tank that penetrates the replenishment hole up and down at the bottom, and a slight gap is secured on the horizontal bottom surface in the replenishment tank facing the replenishment hole, allowing it to rotate around the horizontal axis from a predetermined diameter, horizontal cylindrical idling tube sided outer peripheral wall which is supported on, preventing one or more blades projecting in the centrifugal direction is not buffered in the fuel storage part bottom, the biting of the particulate fuel is conveyed object It is provided so that it protrudes as much as possible and forms a cylindrical spacer blade, and the back of the cylindrical spacer blade that is opposite to the fuel feeding portion in the fuel accommodating portion accommodates the granular fuel. Rotate the rotary drive source at a constant speed, When rotating at a constant speed of 1 rotation per time, one or more blades, forces and intermittently conveyable to particulate fuel intermittently transporting machine a desired amount of particulate fuel toward the fuel infeed section In addition, an output shaft of a replenishing rotary drive source is connected to at least one shaft end of the cylindrical intercostal blade, and the bottom left and right sides of the replenishing tank between the cylindrical interposing blade and the replenishing hole In addition to projecting left and right guide ridges across each of the rivers, a fuel dam partition wall is formed in the replenishment tank above each of the left and right guide ridges. It can be said that it is an automatic fuel intermittent replenisher having a configuration in which an enclosure fuel dam is formed .

    According to the intergranular transfer device for granular fuel of the present invention having the characteristic features as described above, it has been necessary to incorporate a complicated on-off valve mechanism or the like until now. By simply keeping the rotation speed constant or appropriately controlling it, the granular fuel stored in the fuel storage section can be directed to the fuel feed section and intermittently supplied at a desired amount per unit time, and the structure is simple With a small number of parts, it can be manufactured at a small size, light weight, and low cost, and it is possible to realize an efficient and accurate intermittent supply by simple input operation or automatic control. In addition to being able to achieve excellent heat resistance, it can be used as an automatic fuel intermittent replenisher for granular fuel in various combustion devices. In addition, it can be installed in the combustion chamber of various combustion devices and granular fuel in the granular fuel combustion zone. Can be transported Efficient and safe use of granular fuel in various parts of the combustion device for granular fuel, such as supply machines and intermittent ash dischargers that can transfer the combustion ash that has been burned in the granular fuel combustion zone to the trap The excellent feature is that it will be of great use for safe transport.

    In addition, the granular fuel intermittent transfer machine of the present invention, which is provided with only one blade of a cylindrical intercostal blade, can minimize the amount of granular fuel sent out by the blade in one rotation of the idle cylinder face body, and is highly efficient. A small and intermittent stable supply of granular fuel to a combustion device for granular fuel that realizes combustion can be realized simply with the minimum number of parts, while achieving small size, light weight, and low cost, greatly increasing fuel consumption. It is highly effective to be useful for reduction.

    The automatic fuel intermittent replenisher using the granular fuel intermittent transfer device of the present invention has a replenishment tank capable of accommodating granular fuel, and can be incorporated into the fuel hopper of the granular fuel combustion apparatus together with the replenishment tank. In addition, it can be combined with a fuel injection unit of a granular fuel combustion device as a combination with a spiral wing type automatic injection device for granular fuel, etc. It can be easily incorporated into a granular fuel combustion device as an intermittent replenisher for granular fuel injection by incorporating it so as to be placed directly above the combustion device fuel hopper. The enclosed fuel dam can be regulated so that the amount of granular fuel dropped from the replenishing hole is not excessive and insufficient, and a certain amount of granular fuel is supplied more stably and intermittently. The advantage is obtained that it becomes what can and.

    In an automatic fuel intermittent replenisher provided with an automatic number of revolutions control unit capable of individually and integrally controlling two or more cylindrical intercostal blades and each of the replenishment rotary drive sources, the granular fuel is supplied to the normal amount. In the case of intermittent supply, one or a few cylindrical spacer blades are driven to rotate, and in the case of supplying a large amount of granular fuel in a short time, an appropriate number of two or more or all cylindrical spacer blades are used. It can be controlled in an integrated manner so as to be rotationally driven, and an extremely small amount of granular fuel can be intermittently supplied to the combustion chamber of the combustion device to realize low fuel consumption operation, and emergency heating is required. In such a case, a large amount of granular fuel can be intermittently supplied to generate a large amount of heat, and the use range can be greatly expanded.

    The granular fuel intermittent transfer device of the present invention is used as a combustion zone supply unit, and the fuel injection unit is incorporated so that the granular fuel charged into the combustion chamber can be stably and intermittently supplied to the granular fuel combustion zone. The granular fuel combustion device can sequentially transfer new granular fuel to the granular fuel combustion zone, eliminate the interruption of the granular fuel, and realize stable combustion at all times. If the amount of granular fuel transferred to the granular fuel combustion zone is automatically controlled as the fuel supply amount increases or decreases, a more harmonious fuel transfer can be realized.

    The granular fuel combustion apparatus according to the present invention uses the intermittent fuel transfer device as an intermittent discharger and can automatically discharge the combustion ash burned in the granular fuel combustion zone to the combustion ash discharge section. It is possible to quickly eliminate the combustion ash that increases in the combustion chamber and reliably prevent the combustion efficiency from being lowered, and the combustion ash can be taken out from the combustion ash discharge section even when the combustion chamber is burning. Therefore, in the conventional combustion apparatus in which the combustion ash of the conventional type has to be taken out directly from the combustion chamber, it takes time to stop and cool the combustion. However, this is completely unnecessary, and a higher continuous combustion performance can be secured. In addition, since the combustion ash immediately after combustion can be discharged quickly, it is possible to prevent the granular fuel from being baked and sintered in a semi-molten form in the granular fuel combustion zone and solidified into a clinker (ingot) shape. Grudge Very so that the can exhibit Xiu the effect that can be stabilized over gastric burning for a long time.

Smooth supply and quick discharge of the combustion ash burned in the granular fuel combustion zone to the combustion ash discharge section, etc., and further effective combustion can be realized. It will be obtained.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The fuel storage unit of the granular fuel intermittent transfer machine can store a predetermined amount of granular fuel to be intermittently transferred, and the cylindrical intermittent blades rotating the granular fuel intermittent transfer machine can scrape the granular fuel. In addition to the bottom surface shape, the accommodated granular fuel can be transported only by the transfer force of the cylindrical intercostal blade, and one side has a fuel feed section. The shape of the bottom surface should be such that the contained granular fuel does not flow, flow down, or slide down, and can be stably accommodated. Although it can be formed on a curved surface or an inclined surface, it can be said that it is desirable to form it in a horizontal plane as shown in the examples described later.

    In addition, the fuel storage part of the intermittent transfer machine for granular fuel must be provided with a fuel feed part on one side of the bottom surface, and the fuel feed part can correspond to the intermittent supply destination of the granular fuel For example, as shown in the embodiment described later, it is possible to make a replenishment hole penetrating vertically at an appropriate place at the bottom of the replenishing tank when the fuel storage portion is a replenishing tank, When the fuel storage portion is a combustion chamber of a granular fuel combustion device, one of the granular fuel combustion zones arranged at or near the center of the combustion chamber for the granular fuel is a new granular fuel. Combustion ash discharged to the area where the fuel is fed and the fuel feed section is a granular fuel combustion area, or where the fuel injector around the granular fuel combustion area of the combustion chamber for the granular fuel is different The granular fuel combustion zone And regions to be between the combustion ash discharge unit, which fuel infeed unit and the combustion ash discharge unit may be a like.

It is possible to use a casing, a tank, a transfer pipe, a transfer path, etc., incorporating the function of the intergranular transfer device for granular fuel, and as shown in the embodiments described later, the automatic fuel intermittent replenisher itself In addition to a particulate fuel combustion device that can be directly incorporated into a combustion device for granular fuel, a combination of an automatic fuel intercharge replenisher combined with a spiral wing type automatic charging device for granular fuel is used for granular fuel. It can also be incorporated into the combustion apparatus through a fuel hopper or the like.

    The rotary drive source of the particulate fuel intermittent transfer machine has a function to enable stable rotation in a predetermined rotational state suitable for the transfer of granular fuel, and can be driven to rotate at an arbitrary constant rotational speed. In addition to an arbitrary constant rotational speed, the rotational speed can be switched every predetermined time so that it can be continuously driven, intermittently rotated, or those rotational states can be switched appropriately to enable rotational driving, etc. As shown in the embodiments described later, a rotational speed automatic control unit having a temperature sensor capable of detecting the temperature of the combustion chamber of the granular fuel or the temperature of the object to be heated is provided, and the user's set input value, and Depending on the detection value of the temperature sensor, etc., the cylindrical spacer blade can be controlled to a desired rotational speed.

    The cylindrical type intercostals of the granular fuel intermittent transfer machine can set the intermittent supply amount of granular fuel for each rotation according to the number of blades and the contact area of the blades with the granular fuel. Responsible for intermittent supply of a desired amount of granular fuel per unit time by adjusting the rotational speed of the inter-blade blades, either a solid cylinder or a hollow cylinder with the output shaft of the rotary drive source connected to one end It should be either one of at least one blade integrated with the outer peripheral wall of the idle cylinder face made of or attached to be removable and replaceable. In this case, the number, shape, and dimensions of the blades can be easily changed and replaced, and the idle cylinders having dimensions suitable for various powders and granular fuels can be selected from a plurality of idle cylinder faces having different outer diameters. Select the face mask and supply the intermittent amount of granular fuel It can be such that the adjustable.

    Two or more cylindrical spacers of the automatic fuel replenisher are provided, and each unit can be stopped and controlled to rotate. During normal heating, only one unit is driven to rotate, the others are stopped, and rapid heating is performed. Sometimes, depending on the required amount of granular fuel, the starting radix can be increased by one unit, for example, as shown in the examples to be described later, Two rotational drive sources that can be driven individually are provided, and only one cylindrical intercostal blade is activated during normal heating, and another cylindrical intercostal blade that is stopped during rapid heating is also present. It can be activated to supply twice as much granular fuel per unit time.

    The combustion chamber of the granular fuel combustion apparatus burns safely and efficiently while being supplied with a predetermined amount of granular fuel per unit time, and the heat generated thereby is air, water, oil, or other heat medium outside the combustion chamber. As a heat source that can be efficiently transmitted to various industries and used as a heat source that can be used in various industries, as shown in the examples that will be described later, the outside of the combustion device exterior body that incorporates the combustion chamber is relayed. The lower end of the dropping pipe of the fuel hopper consisting of a container part and a dropping pipe suspended from the relay container part has a downward inclination of 40 ° to 70 °, preferably 50 ° to 60 ° with respect to the horizontal surface. It penetrates and connects towards the appropriate place in the room, and is built in such a manner that the replenishment tank replenishment hole of the automatic fuel intermittent replenisher using the granular fuel intermittent transfer machine is arranged directly above the fuel hopper relay container part. With things Rukoto is possible.

It takes out the combustion chamber and can be disposed of, and it must be disposed in a place where fuel injection around the granular fuel combustion zone is different from that of the granular fuel. It may be formed at a position lower than the bottom of the combustion chamber at a location different from the fuel input around the combustion zone, and may have a discharge door that can drop and accumulate combustion ash and can be opened and closed.

The fuel injection unit of the granular fuel combustion device is responsible for the ability to continuously and / or intermittently supply granular fuel from one of the granular combustion chambers in the combustion chamber of the granular fuel combustion device.

(Conclusion)
As described above, the automatic fuel replenishment machine of the present invention can achieve the intended purpose evenly by its new configuration, and is easy to manufacture, simple and inexpensive, and much more economical. Compared to conventional solid fuel supply / combustion technology dedicated to wood pellets, wood chips and wood chips that have been considered unusable as automatic supply fuel for boilers, stoves, etc. Different shaped fuels such as rice husks can also be used smoothly and safely, making it possible to use locally-produced and locally consumed thinned wood and agricultural waste generated in local agriculture and forestry as useful fuel. Not only are the farmers who have been forced to depend on imported imported fossil fuels and have had to bear a large economic burden, but also a large amount of industrial waste such as thinned wood and rice husks. As a result, a new supplier that is advantageous for the agriculture and forestry industry that had to be disposed of properly will be created, and the use of renewable energy will be greatly promoted. In the hot water supply industry and the heater industry, there is a possibility of application to heating of general households and corporate facilities that are worried about soaring utility costs and hope for a friendly environment. It is highly appreciated and expected to be widely used and disseminated.
