Description

  The present invention relates to a garbage processing apparatus for processing garbage using ceramics supporting microorganisms.

  As a garbage processing device for processing garbage discharged from restaurants, lunch centers, ryokan and hotel kitchens, etc., a rotating shaft is provided in the center of the fixed processing tank. A plurality of stirring blades extending radially to the vicinity of the peripheral surface are provided radially, and the plurality of stirring blades are rotated together with the rotating shaft so that the garbage is processed into compost with microorganisms while stirring the garbage put into the treatment tank. Various configurations have been proposed (see, for example, Patent Documents 1 to 6).

  However, in the case where the stirring blade is rotated as described above, there is a problem that foreign matter is entangled with the stirring blade, resulting in malfunctions or deformation of the stirring blade, and the input garbage is treated as a treatment tank. It is rolled in the same shape inside, and the decomposition treatment by microorganisms is not smooth, so it takes a lot of processing time, and the residue after treatment becomes a relatively large lump, and the volume of the residue is not sufficiently reduced. There was a problem.

  Therefore, in order to solve the above problem, the present applicant, as described in Patent Document 7, can treat garbage efficiently and in a short time even if the garbage is input as it is, and can reduce the volume of the residue. As a processing device, a bottomed cylindrical rotation processing tank for processing garbage, an internal resistance plate attached to the inner peripheral surface of the rotation processing tank, and a bottom plate of the rotation processing tank are positioned below A rotation support means for rotatably supporting the rotation processing tank with a rotation center inclined with respect to the horizontal, a driving means for rotating the rotation processing tank, and a crushing ceramic put into the rotation processing tank; The garbage processing apparatus provided with the compression board which compresses garbage in the said rotation processing tank and crushes garbage by cooperation with the said ceramic for crushing was proposed.

  Also, as a garbage disposal device, a plurality of drain holes are formed in the cylindrical body portion of the rotating drum, and the garbage is configured to discharge moisture contained in the garbage to a drainage tank installed below the rotating drum. A processing apparatus has also been proposed (see, for example, Patent Document 8).

  However, in the garbage processing apparatus described in Patent Document 7, since the drainage hole is not formed in the rotation processing tank, the treatment time becomes longer due to the moisture contained in the garbage, or the oil contained in the garbage is rotated. There was a problem of remaining in the treatment tank. Further, for example, it takes 18 hours to decompose 25 kg of raw garbage discharged from a supermarket into a powdery residue, so that further reduction of the processing time has been demanded.

  On the other hand, the invention described in Patent Document 8 is applied to the garbage processing apparatus described in Patent Document 7, and a plurality of drain holes are formed in the body portion of the rotation processing tank to discharge moisture and oil contained in the garbage. However, when the garbage is compressed by the compression plate, part of the garbage that has not been decomposed leaks out of the rotation tank through the drainage hole, or the garbage is clogged in the drainage hole. There is a problem.

  An object of the present invention is to provide a garbage processing apparatus that can shorten the processing time of garbage and can prevent oil from remaining in a rotating treatment tank.

  The inventor of the present invention is directed to a structure for preventing an increase in processing time due to moisture remaining in the rotation processing tank and complicated maintenance due to oil remaining in the garbage disposal apparatus described in Patent Document 7. As a result of earnest examination, by forming a drainage hole that can discharge only moisture and oil so as not to face the compression plate with respect to the compression direction of the garbage by the compression plate in the rear end outer peripheral portion of the rotation processing tank, We found that liquids such as moisture and oil contained in raw garbage can be efficiently discharged out of the rotation processing tank while preventing the crushed raw garbage from clogging the drain hole or being discharged from the drain hole. The present invention has been completed.

  The garbage processing apparatus according to the present invention includes a bottomed cylindrical rotation processing tank for processing garbage, an inner surface resistance plate attached to an inner peripheral surface of the rotation processing tank, and a bottom plate of the rotation processing tank. Rotation support means for rotatably supporting the rotation processing tank by tilting the rotation center backward and downward with respect to the horizontal so as to be positioned on the lower side, driving means for rotationally driving the rotation processing tank, and the rotation processing A crushing ceramic to be put into the tank, a compression plate for compressing the garbage in the rotation processing tank and crushing the garbage in cooperation with the crushing ceramic, and a control means for controlling the drive means In the outer periphery of the rear end of the rotation processing tank, only moisture and oil contained in the garbage are discharged out of the rotation processing tank so as not to face the compression plate in the compression direction of the garbage by the compression plate. To form a drain hole to It is intended.

  In this garbage disposal apparatus, the rotation processing tank is rotated around the rotation center inclined with respect to the horizontal, so that the garbage can be mixed efficiently while entraining air in the garbage thrown into the rotation treatment tank. The activity can be increased and the garbage can be decomposed efficiently. Also, a part of the garbage is sent between the inner peripheral surface of the rotation processing tank and the compression plate and sequentially compressed. At this time, the crushing ceramic is strongly pressed against the garbage and the garbage is finely crushed. . This crushing can increase the surface area of garbage and greatly reduce the processing time of garbage by microorganisms, and can easily decompose garbage into a powdery residue, greatly reducing the volume of the residue. It becomes possible. In addition, a drainage hole is formed in the outer peripheral part of the rear end of the rotation processing tank that is inclined downward to discharge only the water and oil contained in the garbage to the outside of the rotation processing tank. It is possible to smoothly discharge the moisture and oil, and the moisture can be discharged, so that the decomposition processing time of garbage can be shortened and the oil can be discharged to prevent the oil from remaining in the rotation processing tank. This eliminates the need to drain the remaining oil. Moreover, since the drainage hole is formed in the rear end outer peripheral part of the rotation processing tank so as not to face the compression plate with respect to the compression direction of the garbage by the compression plate, the garbage compressed by the compression plate is It is possible to effectively prevent problems such as being discharged to the outside through the drain hole or clogging the drain hole.

  Here, the rotation processing tank is configured in a bottomed cylindrical shape having a cylindrical body portion and a disk-shaped rear surface plate fixed to the rear end portion of the body portion, and the rear surface plate and the body portion are formed into a circular shape. It is a preferred embodiment that welding is performed at intervals in the circumferential direction, and a gap as a drainage hole is formed between the rear plate and the body portion in the non-welded portion. If comprised in this way, it will become possible to form easily the fine clearance gap which cannot pass a garbage in the rear-end outer peripheral part of a rotation processing tank.

  It is a preferred embodiment that a residue receiving box that receives the residue after the garbage treatment is provided below the rotation processing tank so that the moisture and oil can be discharged from the drain hole into the residue receiving box. In this case, since the moisture and oil discharged from the rotation processing tank can be stored in the residue receiving box for storing the powdered residue after the garbage is decomposed, a container for storing the moisture and oil is separately provided. There is no need to provide it, and the work of periodically draining water and oil from the container can be omitted.

  The driving means is controlled by the control means so that the rotation direction of the rotation processing tank is a normal rotation direction in which the garbage can be compressed by the compression plate and a reverse rotation direction in which the garbage cannot be compressed by the compression plate. It is also possible to process garbage by switching sequentially. In this case, the rotation direction of the rotation processing tank is switched by the control means, and the rotation processing is performed not only in the normal rotation direction in which the garbage can be compressed by the compression plate but also in the reverse rotation direction in which the garbage cannot be compressed by the compression plate. Since the tank is rotated, the processing time of garbage can be further reduced. The mechanism that can shorten the processing time of garbage is not clear, but by rotating in the reverse direction, the garbage in the rotating treatment tank is uniformly stirred, and only the rotation in the forward direction causes the compression plate to It can be estimated that the uncompressed raw garbage is rotated in the reverse rotation direction, and is compressed by the compression plate at the next rotation in the normal rotation direction and is crushed.

  The rotation processing means can be rotatably supported by the rotation support means so that the rotation center of the rotation processing tank is inclined by 5 degrees to 25 degrees with respect to the horizontal. By comprising in this way, the said garbage can be mixed efficiently, entraining air in the garbage thrown into the rotation processing tank, the activity of microorganisms can be improved, and a garbage can be decomposed | disassembled efficiently.

  According to the garbage processing apparatus according to the present invention, since the rotation processing tank is rotated around the rotation center inclined with respect to the horizontal, the garbage is efficiently collected while entraining air in the garbage thrown into the rotation processing tank. It can be mixed, and the activity of microorganisms can be increased, so that garbage can be efficiently decomposed. Also, a part of the garbage is sent between the inner peripheral surface of the rotation processing tank and the compression plate and sequentially compressed. At this time, the crushing ceramic is strongly pressed against the garbage and the garbage is finely crushed. . This crushing can increase the surface area of garbage and greatly reduce the processing time of garbage by microorganisms, and can easily decompose garbage into a powdery residue, greatly reducing the volume of the residue. It becomes possible. In addition, a drainage hole is formed in the outer peripheral part of the rear end of the rotation processing tank that is inclined downward to discharge only the water and oil contained in the garbage to the outside of the rotation processing tank. It is possible to smoothly discharge the moisture and oil, and the moisture can be discharged, so that the decomposition processing time of garbage can be shortened and the oil can be discharged to prevent the oil from remaining in the rotation processing tank. This eliminates the need to drain the remaining oil. Moreover, since the drainage hole is formed in the rear end outer peripheral part of the rotation processing tank so as not to face the compression plate with respect to the compression direction of the garbage by the compression plate, the garbage compressed by the compression plate is It is possible to effectively prevent problems such as being discharged to the outside through the drain hole or clogging the drain hole.

A normal rotation direction that can be compressed, and a reverse rotation direction that makes it impossible to compress garbage with the compression plate 6. It is intended to process the next switched garbage. However, it is also possible to control the drive means 5 by the control means 7 so that the rotation processing tank 2 rotates only in the normal rotation direction.

  In the rotation processing tank 2, a microbial bed carrying microbial cells capable of decomposing garbage is prepared prior to the garbage treatment. Specifically, a culture solution of a strain having the ability to decompose garbage is adsorbed on cypress chips, hard porous ceramics, hydroxyapatite, etc., and these are put into the rotation processing tank 2 to produce a fungus bed. Become. Examples of hard porous ceramics include RT and GC manufactured by Miyao Company Limited, and examples of hydroxyapatite include products manufactured by Miyao Company Limited.

However, in the non-welded portion 15, a gap 16 is formed between the rear plate 12 and the body portion 10 as a drain hole that leads from the inside of the rotation processing tank 2 to the outside. The gap 16 is composed of a gap with a fine passage width through which garbage, fungus bed, ceramics for crushing, residues after decomposition of garbage, etc., which are put into the rotation processing tank 2 do not pass. Only the moisture and oil contained in the garbage input to the garbage are left in the bottom of the garbage processing apparatus 1 through the gap 16 from the lower end of the rear end of the rotation processing tank 2 arranged in an inclined manner. It is configured to be discharged. Further, the gap 16 is arranged on the rear side of the rotation processing tank 2 with respect to the compression plate 6 so as not to face the compression plate 6 with respect to the direction in which the garbage is compressed by the compression plate 6, that is, the radial direction of the rotation processing tank 2. Thus, the garbage which is compressed by the compression plate 6 is configured not to be pushed into the gap 16. In addition, the number and length of the welding part 14 and the non-welding part 15 can be arbitrarily set in the range which can ensure the joint strength of the trunk | drum 10 and the rear surface board 12. FIG. Moreover, the welding part 15 can also be provided in the outer surface side of the rotation processing tank 2, and can also be provided in both surfaces of an inner surface side and an outer surface side. Further, in place of the gap 16, a slit is provided at the rear portion of the rear plate 12 or the body portion 10 so as not to face the compression plate 6 in the direction of compression of garbage by the compression plate 6, that is, the radial direction of the rotation processing tank 2. It is also possible to form a hole or a hole so that only water and oil can be discharged.

  The rotation processing tank 2 has a diameter D and a depth H of the rear plate 12, a ratio of the diameter D and the depth H of the rear plate 12, a width L and an inclination of the front plate 11 depending on the processing capacity of the garbage processing apparatus 1. The angle θ is different.

It is received from the lower side by a pair of left and right support rollers 22 that are spaced apart and is rotatably supported.

  At the rear of the support frame 20, there is provided a driving means 5 that rotates the rotation processing tank 2 and restricts the rearward movement of the rotation processing tank 2. The driving means 5 will be described. A shaft member 23 protruding rearward is provided at the center of the rear plate 12 of the rotation processing tank 2, and a speed reducer 24 and a motor 25 are installed at the rear of the support frame 20. The rotation processing tank 2 can be rotated at a reduced speed by rotating the shaft member 23 at a reduced speed by the motor 24 and the motor 25. Further, the backward movement of the shaft member 23 is restricted via the speed reducer 24, whereby the backward movement of the rotation processing tank 2 is restricted. In addition, as a means to support the rotation processing tank 2 rotatably, and a means to rotate the rotation processing tank 2, the thing of arbitrary structures other than the above is employable.

  An inner resistance plate 3 is fixed to the inner peripheral surface of the rotation processing tank 2 at regular intervals in the circumferential direction. The internal resistance plate 3 causes the garbage and crushing ceramics disposed on the lower side of the rotation processing tank 2 to move upward by scraping and moving the garbage and crushing ceramics when the rotation processing tank 2 rotates. This is for efficient and uniform mixing. Specifically, the internal resistance plate 3 having a thickness of 2 to 5 mm and a length of 3/4 to 4/4 of the depth H of the rotation processing tank 2 is 4 to 12 at regular intervals in the circumferential direction. It is attached.

  A front airtight holding plate 30 is provided on the front side of the rotation processing tank 2, an upper airtight holding plate 31 is provided on the upper side of the rotation processing tank 2, and the inside of the garbage processing apparatus 1 includes both airtight holding plates 30, 31 divides the front space 32, the rear space 33, and the upper space 34. The rotation processing tank 2, the rotation support means 4, and the drive means 5 are disposed in the rear space 33.

  A garbage input port 40 is formed on the front surface of the outer plate of the garbage processing apparatus 1, and an open / close door 41 for opening and closing the garbage input port 40 is provided to be openable and closable. A holding plate opening 42 is formed in the front airtight holding plate 30 so as to face the opening 13 of the rotation processing tank 2, and a garbage input port is provided below the holding plate opening 42 in the front airtight holding plate 30. A chute 43 that extends in an upwardly inclined manner toward the side 40 is provided, and the garbage introduced from the garbage input port 40 is guided by the chute 43 and introduced into the rotation processing tank 2.

  A reinforcing plate 44 is fixed to the front side of the front hermetic holding plate 30, and a notch 45 is formed at the center in the left-right direction of the reinforcing plate 44 so as to correspond to the holding plate opening 42. A semicircular support plate 46 disposed in the rotation processing tank 2 through the holding plate opening 42 and the opening 13 of the rotation processing tank 2 is fixed to the reinforcing plate 44 via three spacer members 47. The support plate 46 is provided with a support arm 48 extending substantially horizontally to the left along the front plate 11 in the rotation processing tank 2, and the compression plate 6 is attached to the end of the support arm 48. The compression plate 6 is composed of a plate member having a thickness of 6 mm to 15 mm and a length of 1/2 to 3/4 of the depth H of the rotation processing tank 2, and is inclined from the rotation center C of the rotation processing tank 2. It is attached to the support arm 48 so as to be inclined downward at an angle α = 5 to 20 degrees. By providing such a compression plate 6, the garbage can be efficiently crushed, and even if a small amount of vinyl, plastic tray, foamed styrene fragments, disposable chopsticks, etc. are mixed in the input garbage, Can be crushed.

  An air inlet 50 is formed at the rear of the garbage disposal apparatus 1, and an air duct 51 that extends to the front side of the front airtight holding plate 30 and opens toward the chute 43 is formed at the air inlet 50. A blower fan 52 and a heating unit 53 are provided in order from the upstream side in the middle of the blower duct 51, and the outside air introduced into the blower duct 51 from the intake port 50 is heated by the heating unit 53 and then blown. It is discharged from the duct 51 toward the chute 43, guided by the chute 43, and supplied into the rotation processing tank 2. In this way, by supplying warm air from the air duct 51 into the rotation processing tank 2, the atmosphere temperature in the rotation processing tank 2 is maintained at around 40 ° C. at which the activity of the fungus body becomes high. It is configured to increase the garbage processing speed. In addition, it is also possible to introduce the outside air directly from the air duct 51 into the rotation processing tank 2 by inserting the end of the air duct 51 into the rotation processing tank 2.

  In the present garbage disposal apparatus 1, the garbage is decomposed by the cells while crushing the garbage, so that the garbage is decomposed to a powdery residue, and the residue after the decomposition treatment is the air duct 51. The specific gravity is selected by the hot air supplied from. In other words, garbage, fungus beds, crushing ceramics, etc. that have not been decomposed remain in the rotary treatment tank 2, but the powdery residue after the decomposition is completed is indicated by an arrow in FIG. As indicated by X, air is transported by the hot air supplied from the air duct 51, discharged from the rotary processing tank 2 into the front space 32, and placed in the residue receiving box 17 disposed in the lower part of the garbage processing apparatus 1. It falls and is stored in the residue receiving box 17. Thus, since the residue after the decomposition treatment can be automatically pneumatically transported from the rotation processing tank 2 to the residue receiving box 17, the operation of discharging the residue from the rotation processing tank 2 can be greatly reduced.

  A filter 54, a deodorizing device 55, and an exhaust fan 56 are provided in the upper space 34, and the air in the front space 32 is supplied from the front space 32 to the filter 54 as indicated by an arrow Y in FIG. Then, after the fine residue floating in the air is removed, it is deodorized through the deodorizing device 55 and then discharged from the exhaust port 57 to the outside. As the filter 54, a filter using a nonwoven fabric or the like can be adopted, and a cyclone type filter can also be used. As the deodorizing device 55, an apparatus equipped with adsorption-type activated carbon, a catalyst-type deodorizing agent, or the like can be used. However, an ozone generator can be provided as the deodorizing device 55 to decompose the odor with ozone.

  In the control means 7 of the garbage processing apparatus 1, in addition to the control of the blower fan 52, the exhaust fan 56 and the heating means 53, the rotation direction of the motor 25 is switched every set time to change the rotation direction of the rotation treatment tank 2. By rotating not only the normal rotation direction A in which the garbage can be compressed by the compression plate 6 but also in the reverse rotation direction B in which the compression plate 6 cannot be compressed, the normal rotation and the reverse rotation are alternately performed. The processing time can be shortened. The normal rotation time and the reverse rotation time can be arbitrarily set, but it is preferable to set the normal rotation time to 1 to 3 times, preferably 1.5 to 2.5 times the reverse rotation time, because the processing time of garbage can be shortened. . Specifically, after the normal rotation for 2 hours, the process of reversing for 1 hour is repeated, or after the normal rotation for 4 hours, the reverse rotation process for 2 hours is repeated. However, the forward rotation time and the reverse rotation time can be set in accordance with the characteristics of the garbage to be input, the processing status of the garbage in the garbage processing apparatus 1, and the like.

  The processing time of the garbage is set in advance according to the input amount of the garbage, but when the processing of the garbage is completed, the humidity in the rotation processing tank 2 is lowered, so that the rotation processing tank 2 It is also possible to provide a moisture sensor inside and complete the garbage disposal when the moisture sensor falls below a certain threshold.

Next, a garbage disposal method using the garbage disposal apparatus 1 will be described.
First, before the garbage processing apparatus 1 is operated, the bacteria bed and the crushing ceramics are introduced from the garbage input port 40. The introduction of the fungus bed and the crushing ceramic is basically performed only for the first time, and thereafter, the necessary amount is replenished only when the fungus bed and the crushing ceramic are reduced.

  Next, the garbage is introduced from the garbage input port 40, and the motor 25, the heating means 53, the blower fan 52, and the exhaust fan 56 are operated. As a result, the rotation processing tank 2 rotates at a reduced speed of, for example, 2 to 7 rpm, but the rotation center C of the rotation processing tank 2 is inclined with respect to the horizontal plane P by an inclination angle θ. The thrown garbage is uniformly mixed with the fungus bed and the crushing ceramics while entraining air. Also, the garbage and crushing ceramics are uniformly mixed by scraping the garbage and the crushing ceramics disposed on the lower side of the rotation processing tank 2 upward by the inner resistance plate 3. On the other hand, a part of the garbage is sent between the inner wall of the rotation processing tank 2 and the compression plate 6 and sequentially compressed. At this time, the crushing ceramic is strongly pressed against the garbage, and the garbage is finely crushed. It will be. Thus, the input garbage is uniformly mixed with the fungus bed and the crushing ceramics, and is finely crushed, and the temperature is adjusted to the active temperature of the fungus body by the warm air supplied into the rotary treatment tank 2. As a result, the microorganisms are efficiently decomposed by microorganisms. Further, moisture and oil contained in the garbage are discharged from the lower part of the rear end of the rotation processing tank 2 through the gap 16 to the residue receiving box 17 disposed at the lower part of the garbage processing apparatus 1 to remove the moisture. Thereby, the processing time of garbage can be shortened and it can prevent that this oil component remains in the rotation processing tank 2 by removing an oil component. In addition, in order to accelerate | stimulate discharge | emission of a water | moisture content and an oil content, rotation of the rotation processing tank 2 can also be stopped only for the fixed time in the middle of garbage processing.

  In this way, after the rotation processing tank 2 is rotated forward for a set time, the rotation processing tank 2 is reversed for the set time, and thereafter, normal rotation and reverse rotation are repeatedly performed every set time until the processing of the garbage is completed. Then, garbage is sequentially decomposed by microorganisms. In addition, when the rotation processing tank 2 is reversed, the garbage is not crushed by the compression plate 6, but the garbage in the rotation processing tank 2 is uniformly stirred and only rotating in the normal rotation direction. The raw garbage that has not been compressed by the compression plate 6 is uniformly stirred by rotating in the reverse direction, and is compressed and crushed by the compression plate 6 during the next rotation in the normal direction.

  As described above, the rotation processing tank 2 is inclined with respect to the horizontal plane P, the inner surface resistance plate 3 is provided in the rotation processing tank 2, and the rotation processing tank 2 is rotated forward and reverse. The raw garbage, fungus bed and crushing ceramics are uniformly mixed, and the garbage is finely crushed by the compression plate 6 to increase its surface area, and the temperature in the rotary processing tank 2 is set to the active temperature of the fungus body. By setting to, it becomes possible to decompose the input raw garbage into a powdery residue in a short time.

  In addition, the powdery residue that has undergone the decomposition process is sequentially pneumatically transported from the rotation processing tank 2 into the front space 32 together with the hot air supplied into the rotation processing tank 2, and is put into the residue receiving box 17 by its own weight. The air that falls and is stored in the residue receiving box 17 and discharged from the rotation processing tank 2 into the front space 32 is discharged from the exhaust port 57 to the outside through the filter 54 and the deodorizing device 55. Become.

Next, an evaluation test of the garbage disposal apparatus will be described.
KD-30 manufactured by Environmental Equipment Development Co., Ltd. was used as the garbage disposal device, and 6 kg of cypress chips and 3 kg of hard porous ceramics (GC manufactured by Miyao Company Limited) were used in the rotation processing tank of this garbage disposal device. 3 kg of fungus bed in which a culture solution of Bacillus amyloliquefaciens (NBRC 14141) is immersed and 3 kg of crushing ceramics (Almicron manufactured by Miyao Co., Ltd.) are put in, and the temperature in the rotating tank is kept at 40 ° C. 25 kg of garbage generated from the restaurant was added while the processing tank was rotated three times (3 rpm) per minute.

  Then, under the conditions shown in Table 1, a comparative example in which the rotation processing tank is rotated only in the normal rotation direction, and a rotation process in which the rotation processing tank is rotated in the normal rotation direction for a set time and then rotated in the reverse rotation direction for a set time. The processing time of the garbage in Examples 1-6 which performed repeatedly was measured, respectively. The results are shown in Table 1.

  From Table 1, the processing time can be shortened in the case where garbage is processed while switching between the normal rotation direction and the reverse rotation direction, compared with the case where garbage is processed while rotating the rotation processing tank only in the normal rotation direction. I understand. Further, in Examples 3 and 5 in which the forward rotation time was set to twice the reverse rotation time, the processing time was shorter than in the other examples, and in particular, the forward rotation time was set to 2 hours and the reverse rotation time was set to 1 hour. It can be seen that Example 3 can be processed in the shortest time and can be processed in a processing time of 67% in the case of rotating only in the normal rotation direction.
