Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a processing apparatus for fermenting and decomposing waste organic matters such as human and domestic animal excrement and garbage, and more particularly to a fermentation decomposition processing apparatus suitable for a toilet.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a toilet, a processing device for fermenting and decomposing waste organic substances such as human and livestock manure and garbage is used. As shown in FIG. 7, this fermentation decomposition treatment apparatus 1 includes a processing tank 2, a stirring unit 3 installed in the processing tank, and a driving unit 4 installed outside the processing tank. Then, the processing tank 2 has an upper wall 5 which is entirely openable and closable, and is provided with an opening for feces, an opening for urine, an opening for exhaust, an opening for taking out compost, etc., and introduces manure into the opening. The connection pipes 6, 7, 8 for leading the exhaust air from the opening are respectively erected, and the opening 10 for taking out the compost is further covered with the placing lid 10 with the handle 9.
[0003]
In addition, the stirring unit 3 is configured such that the rotating shaft 11 and the belt-like members 13 (13a, 13b) spirally arranged at the center and divided into two parts along the axis 12 and the belt-like members 13 are equidistant from the axis 12. And a number of support rods 14 that are supported separately. Then, both ends of the rotating shaft 11 are inserted into support holes (shaft holes) provided at the respective centers of the front and rear walls 15 (15a, 15b) of the processing tank 2 and installed. In addition, the winding direction of the belt-shaped member 13 around the rotating shaft 11 is reversed between the front part and the rear part.
[0004]
In addition, a normal motor is used for the drive unit 4, and the rotation shaft 16 and the rotation shaft 11 of the stirring unit 3 are connected by, for example, a chain shaft joint 17. The reason for using the chain joint 17 in this way is to use a cylindrical tube at the center of the rotating shaft 11 when manufacturing the stirring unit 3 and distribute a large number of support rods 14 along the axis 12 of the cylindrical tube. This is because one end of each support rod 14 is fixed to the cylindrical pipe by welding, so that the rotation shaft 11 is liable to be deformed, such as being twisted or bent, and the axes of the two rotation shafts 11 and 16 do not coincide with each other. The motor 4 has one end of the mounting table 18 fixed to the front wall 15b of the processing tank 2 by welding.
[0005]
When such a fermentation decomposition treatment apparatus 1 is used, waste organic substances such as manure and garbage are put into sawdust thrown into the treatment tank 2 from the connection pipe 6 or the like, and the waste organic substances are stirred by the stirring unit 3. Compost can be produced by fermentation by microorganisms while being appropriately transported in the front-rear direction along the axis 12. At this time, it is not necessary to put water or the like in the processing tank 2.
[0006]
However, in the fermentation decomposition processing apparatus 1, the rotating shaft 16 of the driving unit 4 and the rotating shaft 11 of the stirring unit 3 are connected using the chain joint 17, so that the main body of the driving unit 4 and the front wall of the processing tank 2 are connected. The chain shaft joint 17 is interposed between the shaft joint 17 and the shaft joint 15b. Therefore, it is difficult to make the fermentation decomposition treatment apparatus 1 compact so that it can be installed in a narrow place. In addition, since the mounting base 18 of the motor 4 as a driving unit is directly fixed to the processing tank 2 by welding, an impact due to a large torque is strongly transmitted to the processing tank 2 during motor operation, particularly at startup. Therefore, a user who is unfamiliar with such a toilet is surprised by an unexpected impact transmitted to a toilet bowl or the like. The normal motor 4 is started three times a day every eight hours, and is set to continue rotating for a certain period of time.
[0007]
In addition, the impact caused by the torque generated during the motor operation that is periodically generated is constantly strong in the vicinity of the support hole through which the rotating shaft 11 of the stirring unit 3 is inserted and the bearings 19 (19a, 19b) provided therein. Works. Usually, such a bearing 19 uses a metal bearing which is a kind of a sliding bearing. Therefore, if the bearing 19 is used for a long time, foreign substances such as waste organic substances and compost enter between the bearing 19 and the rotating shaft 11. The frictional resistance increases and the support holes are deformed and leak out to the outside. Then, the rotating shaft 11 does not rotate smoothly, bends due to an excessive force acting, and cannot rotate at all.
[0008]
In view of this, the applicant of the present application has previously filed Japanese Patent Application No. 2001-004403, in which the rotating shaft of the driving unit and the rotating shaft of the stirring unit are shared, and a torque arm is interposed between the driving unit and the front wall of the processing tank. By applying an oil seal to the support hole of the rotating shaft opened in the back wall of the processing tank and using a rolling bearing for the bearing of the rotating shaft, the device can be made compact so that it can be installed even in a narrow place. A fermentation decomposition treatment device that can withstand long-term use by reducing the shock applied to the user by attenuating the treatment tank transmission shock caused by the torque during operation and reducing the deformation generated in the stirring section did.
[0009]
[Problems to be solved by the invention]
However, even such a fermentation decomposition treatment apparatus still has problems in maintenance such as inspection and repair. This is because the agitating part of the fermentation decomposition treatment device conventionally supports the rotating shaft and the belt-shaped members arranged in a spiral around the center along the axis, and the belt-shaped members are supported at the same distance from the axis. Consists of multiple support rods. When manufacturing the stirring section, a large number of support rods are generally welded to the rotating shaft, and two belt-shaped members are welded to the support rods. Therefore, when the processing apparatus is operated for a long time, the waste organic matter such as manure and garbage is stirred together with the sawdust by the stirring section, and the fermentation treatment is performed while being transported in the opposite direction along the axis, the stirring is performed. Naturally, the deformation force continues to act on the part. As a result, since the joining portion of the stirring section is once oxidized by welding, it is inevitably mechanically weak and easily separated, and the vicinity thereof is easily deformed or chipped.
[0010]
Therefore, it is necessary to repair the stirrer such as welding and re-joining the separated portion, replacement of parts, and replacement of the entire stirrer. In order to perform such repairs, the stirrer must be removed from the installation location in the processing tank and taken out. Moreover, to take out the stirring section, first enter the building and remove the toilet bowl, urinal, etc. from the treatment tank. Next, after going out of the building and removing the exhaust pipe, the entire processing tank is pulled out from a storage place under the floor as appropriate, a top cover that covers the entire upper surface of the processing tank is removed, and a drive outside the front wall of the processing tank is further removed. Remove the motors, bearings, etc., which are the outer parts of the rear wall.
[0011]
Then, to remove the rotating shaft from the front and rear walls of the processing tank, remove the tank that stores waste organic matter and compost, and slide the rear end of the rotating shaft upward along the vertical hole connected to the shaft hole provided on the rear wall. While the rotation axis is inclined, the front end is pulled out from a shaft hole provided in the front wall of the processing tank. Then, the stirring section can be taken out from the upper opening of the processing tank. Therefore, after repairing damaged parts, etc., the tank is attached, its stirrer or a new stirrer for replacement is returned to a predetermined position in the processing tank, and the motor, bearing, etc. Put on the top cover at the specified position. Then, the processing tank is pushed into a predetermined storage place under the floor, and a return exhaust pipe is provided. Then, the user enters the building again and attaches a toilet bowl, a urinal, and the like, so that the processing apparatus can be used. However, the owner is likely to have anxiety such as invasion of privacy or occurrence of criminal acts due to the entry of a trader into the building. Further, when the owner is out of the office, such maintenance cannot be performed without an administrator or the like.
[0012]
The present invention has been made in view of such conventional problems, and there is no fear of invasion of privacy and occurrence of criminal acts due to entering a building in a building, and fermentation decomposition processing which is easy to maintain. It is intended to provide a device.

[0021]
Then, the stirring unit 22 and the driving unit 23 are attached to both front and rear sides of the support wall 46 as shown in FIG. At this time, a motor, for example, a gad motor that reduces the number of revolutions to 1200: 1 is used as the drive unit 23, and the rotation axis is made common to the rotation axis 38 of the stirring unit 22. In addition, by selecting the size, material, and the like of each member used for the stirring unit 22 and increasing the processing accuracy, a rotating shaft 38 that is less deformed such as twisting or bending is manufactured and used. A substantially equilateral triangular plate-shaped torque arm 55 is interposed between the motor 23 and the processing tank 21, and one end of the torque arm 55 on the bottom side is attached to a motor mounting plate 56 disposed on the processing tank side of the motor 23.

A nut is fitted into the threaded shaft portion of the bolt 62, and the supporting wall 46 is connected to the base wall 45 using the paired bolt 63 and the nut in the other corresponding connecting through holes 48 and 58. . Therefore, with respect to the processing tank 21 having the base wall 45 having the U-shaped opening 47, the support wall 46 provided with the stirring unit 22 and the driving unit 23 on both front and rear sides can be detachably mounted. The part 23 approaches the front wall 43 of the treatment tank 21, and the fermentation decomposition treatment device 20 can be made compact. Then, the front upper lid 24 is closed, and the upper lid 24 is detachably connected to the main body of the processing tank 21 also by using bolts 36 and nuts. Then, the fermentation decomposition treatment apparatus 20 is completed, and can be easily installed even in a narrow storage space such as under the floor. The motor used in the drive unit 23 is protected by covering its head with an upper closed cylindrical cover 64 fixed to the center of the right edge of the front upper lid 24.
[0026]
Prior to use, the fermentation / decomposition treatment apparatus 20 removes sawdust from the feces opening 26 or the lid 34 through the toilet and puts the sawdust into the treatment tank 21 through the compost taking-out opening 29. Then, at the time of use, waste organic substances such as manure and garbage are put into sawdust through a toilet or a urinal, etc., and the waste organic substances are periodically discharged from a stirring unit 22 driven by a motor 23, for example, three times a day for a certain period of time. Stir. Then, each time the stirring section 22 is started, the waste organic matter and the produced compost etc. are first collected in the center of the inside of the processing tank 21 while stirring, and thereafter, the conveyance is repeated in the front-back direction so that the microorganisms are fermented. At this time, the impact generated by the operation of the motor 23 due to a large torque, particularly at the time of starting, can be absorbed and attenuated by the torque arm 55 and transmitted to the processing tank 21. Therefore, the deformation which hinders smooth rotation such that the cylindrical tube 39 forming the central portion of the rotating shaft 38 of the stirring section 22 is bent does not occur. In addition, the front wall 43 is provided with an oil seal and the rolling bearing 53 is used for the both shaft holes 50, 60, etc. of the rotating shaft 38 opened in the front and rear walls 43, 44, etc. of the processing tank 21, and the rotating shaft can be freely inserted and removed in the rear wall 44. Since the mold seal bearing 54 is used, a part of the waste organic matter and compost does not leak to the outside from the shaft hole 50 or the like, and the rotating shaft 38 continues to rotate smoothly.
[0027]
However, if the stirrer 22 is continuously used for a long period of time, the joining portion or the like of the stirrer 22 by welding is separated, and a part thereof is deformed or chipped. In that case, maintenance such as inspection and repair is required. Therefore, at the time of maintenance, the exhaust pipe may be removed from the front upper lid 24 of the processing tank 21 constituting the fermentation decomposition processing apparatus 20, and the front upper lid 24 may be removed by removing bolts 36, nuts and the like. There is no need to enter the toilet and remove the toilet or urinal from the rear upper wall 25 of the processing tank 21. Therefore, there is no danger of invasion of privacy or occurrence of criminal acts due to entering a business in the building. Then, the bolts 62, 63, nuts, etc. of the support wall 46 constituting the front wall 43 of the processing tank 21 are further removed. Then, by using the upper wall opening by removing the front upper lid 24 of the processing tank 21 and the U-shaped opening 47 into and out of the agitating portion at the upper center of the base wall 45, the agitation integrally provided on the support wall 46 together with the driving portion 23. The part 22 can be appropriately moved forward, or can be taken out of the processing tank 21 to inspect and repair necessary parts. After the repair or the like, the agitating unit 22 is returned to the processing tank 21 and set back, and the support wall 46 is joined to the base wall 45 to form the front wall 43, and the upper wall opening is closed by the front upper cover. By closing at 24 and attaching an exhaust pipe, the use of the fermentation decomposition treatment tank 20 can be resumed. Therefore, maintenance of the fermentation decomposition treatment tank 20 is simple.
