Description

  The present invention relates to an organic matter decomposing apparatus that decomposes general garbage and other organic matters using magnetized air.

  It is known that when a magnetic field is applied to air, an air flow is generated due to a difference in behavior in the magnetic field for each simple gas contained in the air. A technology that uses this technology for waste decomposition (low-temperature combustion) is drawing attention as an environmentally friendly method that does not use fossil fuels.

  As an organic matter decomposition apparatus using magnetized air, there is, for example, Patent Document 1. In the decomposition apparatus of Patent Document 1, various conditions such as the shape of the decomposition chamber, the number and position of the ventilation pipes, the structure of the openings of the ventilation pipes, and the strength of the magnetic force are limited to specific ranges. According to this, it is described that adjustment of magnetized air can be made unnecessary with a simple structure, and the size can be changed according to the installation location and installation cost.

JP 2013-27808 A (published February 7, 2013) Japanese Patent No. 3716348 JP 2014-025599 A (published February 6, 2014)

  However, in the decomposition apparatus of Patent Document 1, when the length of all sides of the bottom surface of the decomposition chamber (when the shape of the bottom surface is a square or a rectangle) is longer than 240 cm, the waste processing efficiency decreases, It is described that it is not practical, and it is impossible to realize a large device whose bottom side exceeds 240 cm.

  This invention is made | formed in view of the said subject, The objective is to provide the organic substance decomposition | disassembly apparatus corresponding to the enlargement which can implement | achieve the size whose side of a bottom surface exceeds 240 cm.

  In order to increase the processing capacity of the organic matter decomposition apparatus, it is essential to increase the size of the bottom surface of the decomposition chamber. However, when the size of the bottom surface is increased, it becomes difficult to supply sufficient magnetized air to the center of the decomposition chamber with the vent pipe provided on the side wall in contact with the periphery of the bottom surface. This is because the vent pipe extending from the side wall of the decomposition chamber does not extend to the center of the decomposition chamber and stays in the vicinity of the side wall so as not to obstruct the passage and deposition of the thrown object. If the magnetized air is insufficient, the processing efficiency is lowered and the processing capacity cannot be increased.

  The inventor of the present application has conducted extensive studies so that magnetized air can be sufficiently supplied to the center of the decomposition chamber even when the size of the bottom surface of the decomposition chamber is increased. And, it is found that the air pipes are arranged so that magnetized air from the air pipes having different heights is supplied to each space obtained by dividing the space in the decomposition chamber into a plurality of spaces, by varying the heights thereof. It came to perform this invention.

  That is, the organic matter decomposing apparatus of the present invention includes a plurality of vent pipes for supplying magnetized air to the inside of the decomposition chamber. In the organic matter decomposing apparatus for decomposing an organic matter to be processed deposited in the decomposition chamber, A plurality of first vent pipes disposed on a side wall of the decomposition chamber, and a plurality of second vent pipes disposed on a bottom surface of the decomposition chamber, wherein the second vent pipe extends from the bottom surface. It is characterized in that it has different heights and is distributed so that magnetized air can be supplied to each divided space obtained by dividing the actual processing space in the decomposition chamber into a plurality.

  The organic matter decomposition apparatus of the present invention further includes a sealable space provided outside the side wall and the bottom surface of the decomposition chamber, and an open / close mechanism that communicates the sealable space with the outside. Each air intake port of a 1st ventilation pipe and the said 2nd ventilation pipe is arrange | positioned, and it can also be set as the structure by which a flow volume variable mechanism does not exist in a said 1st ventilation pipe and a said 2nd ventilation pipe.

  In the organic matter decomposing apparatus of the present invention, at least a part of the first vent pipe has an air intake port positioned outside the decomposition chamber above an air exhaust port positioned inside the decomposition chamber. A certain configuration may be adopted.

  According to the present invention, there is an effect that it is possible to provide an organic matter decomposing apparatus corresponding to a large size capable of realizing the size of the bottom side exceeding 240 cm.

(Embodiment 1)
Embodiments of the present invention will be described with reference to the drawings. In the following explanation, as combustible materials to be treated, in addition to paper waste, many combustible materials such as food waste, combustible organic matter, livestock waste, medical waste, etc. Waste is targeted. Hereinafter, they are collectively referred to as an object to be processed.

  The organic matter decomposition apparatus according to the present embodiment decomposes organic matter by low-temperature burning in a processing space into which magnetized air is fed, and finally converts it into ceramic ash. Low temperature combustion is different from the state in which the object to be processed burns with flames, and is to burn the object to be processed while supplying a small amount of air, or in a steamed state.

  FIG. 1 is a front view of an organic matter decomposing apparatus 1 according to this embodiment, and FIG. 2 is a plan view of the organic matter decomposing apparatus 1. As shown in FIGS. 1 and 2, the organic matter decomposing apparatus 1 has a decomposition chamber 2 that decomposes an object to be processed by low-temperature combustion in an internal processing space 12 (see FIG. 3). The outer shape of the decomposition chamber 2 is preferably a cube or a rectangular parallelepiped as shown in FIGS. 1 and 2, but may be a cylinder or a polygonal column. Here, the decomposition chamber 2 has, for example, a rectangular parallelepiped shape having a bottom surface of 200 cm × 200 cm and a height of 255 cm.

  An ash discharge port 6 is provided at the bottom of the decomposition chamber 2 for taking out ash which is a decomposition product of the object to be processed. By opening the door of the ash discharge port 6, a cleaning opening 35 (see FIG. 4) described later is exposed, and the ash inside can be discharged. In addition, a space 13 having a height enough for a person to enter is provided below an installation surface such as the ground on which the organic matter decomposition apparatus 1 is installed. The ash at the center of the decomposition chamber 2 that is difficult to be discharged from the cleaning opening 35 is collected in the space 13 by a hopper (not shown) provided at the bottom of the decomposition chamber.

  On the decomposition chamber 2, a charging unit 3 having a workpiece input port 7 with a lid, a deodorizing and smoking device 4, and a chimney 5 are provided. The input unit 3 temporarily stores the processing object input from the processing object input port 7 in the internal stock space 11 (see FIG. 3). The material of the decomposition chamber 2 and the charging unit 3 is preferably a heat-resistant metal such as, for example, a material mixed with stainless steel, iron, or iron, an aluminum alloy, a magnesium alloy, or geralumin.

  The deodorization / smoke removal device 4 deodorizes and smoke-removes dry distillation gas generated by burning an object to be processed in the decomposition chamber 2. The chimney 5 discharges the exhaust gas processed by the deodorizing and smoke eliminating device 4. Although not shown in the figure, the organic matter decomposition apparatus 1 has heat generated when the deodorizing and smoking apparatus 4 burns dry distillation gas and heat of dry distillation gas from the decomposition chamber 2 to the deodorizing and smoking apparatus 4. May be configured to further include a water heater or a power generator that uses the heat as exhaust heat.

  In the organic matter decomposition apparatus 1 of the present embodiment, the decomposition chamber 2 has a height of, for example, about 255 cm, and the charging unit 3 further has a height of about 150 cm. Therefore, in the organic matter decomposition apparatus 1, decks 8 and 9 that surround the decomposition chamber 2 and the charging unit 3, and a staircase 10 are provided.

  FIG. 3 is a longitudinal sectional view showing the internal structure of the organic matter decomposing apparatus 1, and FIG. 4 is a longitudinal sectional view showing the structure of the bottom of the organic matter decomposing apparatus 1. As shown in FIG. 3, a stock space 11 for temporarily stocking the object to be processed is provided inside the charging unit 3, and a processing space 12 for burning the object to be processed at a low temperature is provided inside the decomposition chamber 2. Is provided. The stock space 11 and the processing space 12 are communicated and sealable spaces.

  An openable movable bottom 14 is provided at a communication port that allows the stock space 11 and the processing space 12 to communicate with each other. The object to be processed put into the stock space 11 is put into the processing space 12 when the movable bottom 14 is opened. The workpieces thrown into the processing space 12 are stacked and accommodated in the processing space 12 and ignited, so that the one located at the bottom is sequentially decomposed into ceramic ash.

  At the bottom of the decomposition chamber 2, there are provided an ash recovery part 30 for recovering ceramicized ash and a bottom sealable space 31. The ash collection unit 30 collects the ceramic ash and the pyroligneous acid produced with combustion.

  As shown in FIG. 4, the ash collection unit 30 has a first bottom plate 32 made of expanded metal that forms the bottom surface of the processing space 12. Below the first bottom plate 32, a second bottom plate 33 made of punching metal having a hole smaller than the first bottom plate 32 is disposed. The ceramicized ash passes through the first bottom plate 32 to become primary ash, and the primary ash passes through the second bottom plate 33 to become finer secondary ash. The hole diameter (diameter) of the second bottom plate 33 is preferably 2 mm to 20 mm.

  The ash (primary ash and secondary ash) in the center of the decomposition chamber 2 is collected by dropping into the underground space 13 via a hopper (not shown), and ash (primary ash and secondary ash) near the wall of the decomposition chamber 2. Is recovered from the cleaning opening 35 (with a cap). In addition, it is good also as a structure which provides a hopper in the whole region of the bottom face of the processing space 12, and drops all the ash (primary ash and secondary ash) to the underground space 13.

  By the way, in the conventional organic matter decomposition apparatus, it was recognized that ceramicized ash was required in the processing space 12 in order to excite magnetic force and start decomposition of organic matter. However, the inventor of the present application has found that even if there is no ceramicized ash in the processing space 12, the magnetic force is excited and organic matter decomposition is started as long as there is a seed fire as a heat source. Therefore, in the organic matter decomposition apparatus 1 in the present embodiment, it is not necessary to put ceramicized ash in the processing space 12.

  The ash collection unit 30 is provided with a wood vinegar collection chamber 36 for collecting wood vinegar, and the wood vinegar over a certain amount is overflowed to the outside. By storing the pyroligneous acid solution in the processing space 12, necessary moisture is supplied from the pyroligneous acid vapor to the processing space 12. If the water is insufficient during the processing, the processing speed is reduced, but this makes it unnecessary to supply water during the processing.

  The bottom sealable space 31 is formed between the ash collection unit 30 and the installation surface on which the organic matter decomposition apparatus 1 is installed. A space between the bottom sealable space 31 and the ash collection unit 30 is separated by a strong third bottom plate 34. The bottom sealable space 31 is provided with a base 39 in which a plurality of steel materials such as H steel are arranged in a lattice shape. The base 39 is provided with openings 39a at important points, and a plurality of bowl-shaped spaces partitioned by the base 39 communicate with each other through the openings 39a. And the air hole 37 is formed in the part located in the outer edge of the organic matter decomposition | disassembly apparatus 1 in the base 39, By closing this air hole 37, the bottom part sealable space 31 can turn into a substantially sealed space. .

  The above-mentioned hopper (not shown) is joined to the opening formed in the third bottom plate 34 by a method such as welding, and the tip side thereof is provided to reach the space 13 below the installation surface via the bottom sealable space 31. It has been. An opening / closing mechanism such as a valve is attached to a portion of the hopper that reaches the space 13.

  Returning to FIG. 3, the decomposition chamber 2 has an inner wall 16 disposed at a predetermined interval inside the outer wall 15 of the decomposition chamber. The inner wall 16 is provided so as to go around the processing space 12, and a side space 17 is formed between the inner wall 16 and the outer wall 15. In addition, a constant distance is maintained between the upper end of the inner wall 16 and the ceiling surface of the processing space 12, and a plurality of side spaces 17 and the processing space 12 communicate with each other on the lower end side of the inner wall 16. An opening 16a is provided.

  Thereby, during combustion of the object to be processed, the carbonization gas generated in the processing space 12 rises in the processing space 12, hits the movable bottom 14, is guided to the side space 17, and contacts the outer wall 15 to generate heat. It is lowered by being taken away, and is again provided to the combustion site through the opening 16a. A part of the dry distillation gas that has risen in the processing space 12 is sent to the deodorization and smoke removal apparatus 4 (see FIG. 1).

  The inner wall 16 is formed with a slit portion 16b (see FIG. 5) for absorbing strain (thermal stress) due to thermal expansion. The slit portions 16b are slit-like openings extending from the upper end to the lower end of the inner wall 16, and are provided at four locations in the example of FIG.

  An enclosure wall 18 having a U-shaped cross section is provided outside the outer wall 15 of the decomposition chamber 2 and around the outer side of the decomposition chamber 2 in the lower half of the decomposition chamber. Between, the side sealable space 20 which can be sealed is formed. An opening / closing mechanism 21 for taking outside air into the side sealable space 20 is provided at the lower part of the enclosure wall 18. Although details of the opening / closing mechanism 21 will be described later, the side sealable space 20 is configured by shifting the positions of the through holes 47 and 48 (see FIG. 8) provided in the opening / closing mechanism 21 to block the passage of air. It can be a substantially enclosed space.

  Further, in the actual processing space 12a in the lower half of the decomposition chamber 2, a horizontal vent pipe (first vent pipe) 23 and a vertical vent pipe (second vent pipe) 25, each having a magnetic field generator 24, are disposed. Has been. The actual processing space 12a corresponds to the lower half of the processing space 12, and is a portion where the processing object is deposited and the decomposition processing of the processing object is actually performed.

  The horizontal ventilation pipe 23 and the vertical ventilation pipe 25 supply magnetized air to the processing space 12, specifically the actual processing space 12 a, and the magnetic field generator 24 is the air passing through the horizontal ventilation pipe 23 and the vertical ventilation pipe 25. Is magnetized.

  Although not shown, the magnetic field generator 24 has a configuration in which permanent magnets are housed in an annular magnet housing housing attached to the horizontal vent pipe 23 or the vertical vent pipe 25. The permanent magnets are arranged at positions where different poles (N pole and S pole) or the same poles (S pole and S pole, N pole and N pole) face each other, and a magnetic field is perpendicular to the air flow. Is generated. Thereby, the air passing through the horizontal vent pipe 23 and the vertical vent pipe 25 is activated and magnetized by negative ionization of molecules, and becomes magnetized air.

  The lateral ventilation pipe 23 is disposed laterally from the side sealable space 20 on the outer periphery of the decomposition chamber 2 toward the inside of the inner wall 16 and is supported by the outer wall 15 and the inner wall 16. An air intake port in the lateral ventilation pipe 23 is located in the side sealable space 20, and a magnetic field generator 24 is attached to a portion located in the side sealable space 20. The air discharge port in the horizontal vent pipe 23 is located inside the inner wall 16, and an end portion where the air discharge port is provided is cut obliquely so that air can be discharged downward.

  Such lateral ventilation pipes 23 are arranged with a predetermined interval over the entire circumferential direction of the decomposition chamber 2, and a plurality of the horizontal ventilation pipes 23 with a predetermined interval from the vicinity of the first bottom plate 32 which is the bottom surface of the processing space 12. Layers are provided. In the example of FIG. 3, four layers are provided.

  On the other hand, the vertical vent pipe 25 is disposed vertically from the bottom sealable space 31 at the bottom of the decomposition chamber 2 through the third bottom plate 34, the second bottom plate 33, and the first bottom plate 32 toward the processing space 12. ing. The vertical ventilation pipe 25 is supported by a base 38 (see FIGS. 4 and 5) of the organic matter decomposition apparatus 1 disposed at the bottom of the decomposition chamber 2 or by a frame 38 provided at the center. By being along the frame 38, it is possible to suppress the impact received from the loaded processing object and the deformation of the vertical vent pipe 25 due to the weight of the processing object.

  Although not shown, when the position of the vertical vent pipe 25 overlaps with the position of the hopper described above, the vertical vent pipe 25 is disposed so as to penetrate the hopper, and the boundary is formed by welding or the like. It is joined. Thereby, the airtightness of the processing space 12 is maintained.

  The air intake port in the vertical vent pipe 25 is located in the bottom sealable space 31, and the magnetic field generator 24 is attached to a portion located in the bottom sealable space 31. An air discharge port in the vertical vent pipe 25 is located inside the processing space 12, and an end portion having the air discharge port is curved by 180 degrees so that air can be discharged downward.

  A plurality of such vertical vent pipes 25 are provided with different heights from the vicinity of the bottom surface (first bottom plate 32) of the processing space 12. In the example of FIG. 3, the vertical vent pipe 25 has a height of three stages, and is distributed and arranged on the center side of the actual processing space 12 a where the magnetized air supplied from the horizontal vent pipe 23 does not spread. .

  FIG. 5 is a cross-sectional view of the decomposition chamber 2 of the organic matter decomposition apparatus 1. In FIG. 5, differences in height of the vertical vent pipe 25 are indicated by A, B, and C. FIG. 6 is a diagram showing an image for dividing the actual processing space 12a.

  As shown in FIG. 5, the horizontal ventilation pipes 23 are arranged at a predetermined interval over the entire circumferential direction of the decomposition chamber 2. In the example of FIG. 5, the multiple layers of the horizontal ventilation pipes 23 are arranged so as to overlap in a plan view, but may be arranged with their positions shifted in the circumferential direction.

  On the other hand, the vertical vent pipes 25 having different heights are distributed and arranged so that magnetized air can be supplied to each divided space obtained by dividing the actual processing space 12a. In the example of FIG. 5, three (A, B, C) vertical ventilation pipes 25 having different heights are arranged so that areas where the magnetized air discharged from each overlaps overlap each other in plan view. .

  As shown in FIG. 6, the vertical vent pipe 25 is arranged so that the magnetized air can be reliably supplied to each divided space S that divides the actual processing space 12 a and is surrounded by a dotted line. Specifically, the actual processing space 12a is divided into, for example, 40 cm square cubes or 50 cm square cube divided spaces S, and the amount of magnetized air (or magnetized air concentration) supplied to each divided space S is determined. The vertical ventilation pipes 25 having different heights are dispersed and arranged so as to have an amount (or concentration) necessary for the decomposition of the object to be processed.

  However, since the magnetized air is supplied from the lateral ventilation pipe 23 to the divided space S in contact with the inner wall 16, the vertical ventilation pipe 25 is not provided in the divided space S in contact with the inner wall 16 or from the central portion. Also, the number to be arranged may be reduced. Note that the size of the divided space S is appropriately determined depending on the power of the magnetic field generator 24, the supply amount of magnetized air, and the like.

  By arranging the vertical ventilation pipe 25 in this way in addition to the horizontal ventilation pipe 23, the processing efficiency can be maintained even if the organic matter decomposing apparatus 1 is enlarged to a size having a bottom side exceeding 240 cm. A high organic matter decomposition apparatus 1 is obtained.

  FIG. 7 is a vertical cross-sectional view of a main part where the horizontal ventilation pipe 23 and the vertical ventilation pipe 25 are disposed in the organic matter decomposition apparatus 1. (A) shows the principal part cross section in which the horizontal ventilation pipe 23 is arrange | positioned, (b) shows the principal part cross section in which the vertical ventilation pipe 25 is arrange | positioned.

  As shown to (a), the reducer 41 which restrict | squeezes an internal diameter is connected to the other end of the outer side piping 40 in which the one end is located in the side part sealable space 20. And the inner side piping 42 is attached so that the outer periphery of the reducer 41 may be covered. The tip of the reducer 41 is located inside the inner wall 16. Here, the inner diameter of the outer pipe 40 is, for example, 40 mm, and the inner diameter of the tip portion of the reducer 41 is, for example, 20 mm. The inner diameter of the inner pipe 42 is 40 mm, for example. In the example shown in the drawing, the strength of the inner pipe 42 is increased as a double structure in which another pipe with an inner diameter of 50 mm is placed outside the pipe with an inner diameter of 40 mm and an outer diameter of 50 mm.

  Thus, by providing the reducer 41 and reducing the diameter of the air discharge port more than the diameter of the air intake port, the flow rate of the magnetized air can be reduced without providing a flow rate variable mechanism such as a valve that changes the supply amount of the magnetized air. The flow rate can be increased to contribute to organic matter decomposition.

  When the magnetic processing apparatus (about 4000 to 5000 gauss) having the configuration described in Patent Document 2 is used as the magnetic field generator 24, the inventor of the present application changes the inner diameter of the outer pipe 40 from 40 mm to the inner diameter of 20 mm by the reducer 41. It has been confirmed that the valve is no longer necessary by narrowing down.

  Conventionally, in the organic matter decomposition apparatus using the magnetic processing apparatus having the configuration described in Patent Document 3, the valve is positioned as an essential configuration. In this way, the reducer 41 is provided to provide a flow path for magnetized air. A valve can be made unnecessary by narrowing the diameter of the tube appropriately.

  Further, as shown in (b), the reducer 41 is connected to the other end of the outer pipe 40 whose one end is located in the bottom sealable space 31 in the vertical vent pipe 25 as well as the horizontal vent pipe 23. In the vertical vent pipe 25, the reducer 41 is attached with an inner pipe 43 whose tip is curved 180 degrees. The inner pipe 43 is configured to be thicker than the outer pipe 40.

  In the configuration in which a plurality of the horizontal ventilation pipes 23 and the vertical ventilation pipes 25 are provided, if a valve is provided individually, a complicated operation for adjusting the valve occurs. In particular, in the case of the vertical ventilation pipe 25, since the valve is provided at the lower part of the organic matter decomposing apparatus 1, it is necessary to adjust the valve by diving under the floor, which is a very complicated operation. However, by adopting such a configuration that does not use a valve, workability is greatly improved even when a plurality of the horizontal ventilation pipes 23 and the vertical ventilation pipes 25 are arranged.

  FIG. 8 is an explanatory view showing the structure of the opening / closing mechanism 21 provided in the organic matter decomposing apparatus 1. (A) shows the state which made the side part sealable space 20 connect with the exterior, (b) interrupted | blocks the side part sealable space 20 from the exterior, and made the side part sealable space 20 into substantial sealed space. It shows the state.

  The opening / closing mechanism 21 is attached substantially horizontally to the lower part of the enclosure wall 18 (see FIG. 3) described above. As shown in (a) and (b), the opening / closing mechanism 21 includes a fixed side member 45 fixed to the enclosure wall 18 and a movable side member 46 slidably attached to the fixed side member 45. . The fixed side member 45 is provided with a plurality of through holes 48, and the movable side member 46 is also provided with a plurality of through holes 47. Further, the movable member 46 is provided with a U-shaped operation piece 49 that also serves as a stopper at both ends in the longitudinal direction. The plurality of through holes 47 and the plurality of through holes 48 are provided at positions where they can be overlapped.

  In a state where the plurality of through holes 47 and the plurality of through holes 48 are overlapped as shown in (a), an air hole 50 is formed, the side sealable space 20 communicates with the outside, and the side sealable space 20 is formed. Air is taken in. From the state shown in (a), when the movable side member 46 is slid by hitting the left operation piece 49 with a hammer or the like in the more protruding view, the plurality of through holes 47 and the plurality of through holes 48 do not overlap. The state shown in (b) is obtained. In the state shown in (b), the air hole 50 is not formed, air is not taken into the side sealable space 20, and the side sealable space 20 becomes a substantially sealed space. From the state shown in (b), the plurality of through holes 47 and the plurality of through holes 48 are overlapped again by hitting the operation piece 49 on the right side and sliding the movable side member 46 in the more protruding view. The state shown in FIG. Of course, a configuration may be adopted in which a motor or the like is provided and the movable side member 46 is slid by the driving force.

  By providing such an opening / closing mechanism 21 and allowing the side sealable space 20 to be a sealed space as necessary, even when the lateral ventilation pipe 23 is not provided with a variable flow rate mechanism such as a valve, It is possible to block the air supply to the processing space 12. Moreover, since the plurality of air holes 50 can be closed at once, the workability is excellent.

  The blockage of the air hole 50 is necessary when extinguishing the fire inside the processing space 12. When the fire inside the processing space 12 is extinguished, the air hole 37 formed in the bottom sealable space 31 is also closed.

  FIG. 9 is a cross-sectional view of the decomposition chamber 112 of the organic matter decomposition apparatus 100 according to the modification. The organic matter decomposition apparatus 100 is a large apparatus having a bottom surface of the decomposition chamber 112 of, for example, 400 cm × 400 cm. In such a large apparatus, as shown in FIG. 9, it is preferable to provide a plurality of frames 38 to support the vertical vent pipe 25. Further, the frame 44 located at the center may be provided with a gable-shaped roof so that the workpieces to be thrown are distributed to a space where the left and right vertical ventilation pipes are densely packed. In FIG. 9, except for the vertical ventilation pipe 25 supported by the frame 44, the bending of the tip portion is omitted. Further, the difference in height of the vertical vent pipe 25 is also omitted.

  In a large apparatus having a bottom surface of the decomposition chamber 112 exceeding 400 cm × 400 cm, a basement-like ash storage chamber is provided below the organic matter decomposition apparatus 100, and secondary ash is supplied to the ash recovery unit 30. It is preferable to provide a hopper member to be dropped. The amount of ash to be discharged increases as the processing capacity of the organic matter decomposing apparatus 100 increases. With this configuration, the ash can be introduced into the ash storage chamber by its own weight.

  FIG. 10 is a view showing a modification of the charging unit that can be employed in the organic matter decomposing apparatus 1, 100. As shown in FIG. 10, the charging unit 103 includes a rotary drum 120 in the internal space. The rotary drum 120 includes a semicircular fixed frame 121 fixed at a position immediately below the workpiece input port 107 and a hollow drum main body 122, and the drum main body 122 is rotatable with respect to the fixed frame 121. Is provided.

  The fixed frame 121 and the drum body 122 are formed with the same openings 121a and 122a extending in the central axis direction. Since the openings 121a and 122a overlap, the workpiece can be put into the stock space 111 inside the drum body 122. Although not shown, a handle for rotating the drum body 122 is provided in the axial direction of the drum body 122. By rotating the drum body 122, the workpieces temporarily stocked in the stock space 111 can be put into the processing space 12 of the decomposition chamber 2.

  The details of the charging unit provided with such a rotary drum 120 are described in detail in Patent Document 3 to which the present inventor has previously applied for a patent.

  Here, it should be noted that a seal member 125 that closes the gap between the fixed frame 121 and the drum body 122 is provided. The seal member 125 is in contact with the drum main body 122 at the front end thereof, and the drum main body 122 rotates so as to slide on the front end of the seal member 125.
