Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for fermenting and decomposing waste organic matters such as manure and garbage of humans and livestock, and more particularly to a fermentation decomposition processing apparatus suitable for toilets.

[0002]

2. Description of the Related Art Conventionally, as a toilet, a processing apparatus for fermenting and decomposing waste organic substances such as human and livestock excreta and garbage has been used. As shown in FIG. 4, the fermentation decomposition processing 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 as an upper lid 5, and an opening for feces, an opening for urine, an opening for exhaust, an opening for taking out compost, and the like are provided therein.
Manure is introduced into the opening, connection pipes 6, 7, and 8 for leading exhaust air out of the opening are respectively erected, and a storage lid 10 with a handle 9 is provided in the opening for taking out compost.

The agitating section 3 is composed of a rotating shaft 11, a belt-like member 13 (13a, 13b) which is divided into two parts at the center along an axis 12 and is spirally arranged, and a belt-like member 13 such as these. And a number of support rods 14 which are supported at equal distances. Then, both ends of the rotating shaft 11 are inserted into support holes provided at the respective centers of the left and right side walls 15 (15a, 15b) of the processing tank 2 and installed. The winding direction of the belt-shaped member 13 around the rotation shaft 11 is reversed between the left side portion and the right side portion.

In addition, a normal motor is used for the drive unit 4, and a rotation shaft 16 of the drive unit 4 is connected to a rotation shaft 11 of the stirring unit 3 by, for example, a chain joint 17. The reason for using the chain joint 17 in this way is to use a cylindrical pipe at the center of the rotating shaft 11 when manufacturing the stirring section 3 and distribute a number of support rods 14 along the axis 12 of the cylindrical pipe. This is because one end of each support rod 14 is fixed to the cylindrical tube by welding, so that the rotation shaft 11 is liable to be deformed, such as being twisted or bent, and the axes of the rotation shafts 11 and 16 do not coincide with each other. The motor 4 is fixed by welding one end of the mounting base 18 to the right side wall 15b of the processing tank 2.

[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 these are stirred by the stirring section 3. Then, fermentation can be performed by microorganisms while being appropriately conveyed in the left-right direction along the rotation axis 12 to produce compost. At this time, it is not necessary to put water or the like in the processing tank 2.

[0006]

However, in such a fermentation decomposition treatment apparatus 1, since 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, Main body of drive unit 4 and right side wall 1 of processing tank 2
5b is interposed with the chain joint 17. Therefore,
It is difficult to make the fermentation decomposition apparatus 1 compact so that it can be installed in a narrow place. Also, a mounting base 18 for the motor 4 as a driving unit.
Is directly fixed to the processing tank 2 by welding, so that an impact due to a large torque is strongly transmitted to the processing tank 2 when the motor is operated, particularly when the motor is started. Therefore, a user who is unfamiliar with such a toilet is surprised by an unexpected impact transmitted to a toilet bowl or the like. In addition,
Normally, the motor 4 is started three times a day every eight hours, and is set to continue rotating for a certain period of time.

In addition, the impact caused by the torque generated during the motor operation, which is generated periodically, is constantly generated in the vicinity of the support hole through which the rotating shaft 11 of the stirring unit 3 is inserted and the bearing 19 provided therein.
(19a, 19b). Usually, such a bearing 19 uses a metal bearing which is a kind of a sliding bearing. Therefore, when the bearing 19 is used for a long time, foreign substances such as waste organic matter 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
May not rotate smoothly, may bend due to excessive force, and may not rotate at all.

The present invention has been made in view of such a conventional problem. The apparatus can be made compact so that it can be installed even in a narrow place, and the processing tank transmission caused by the torque during operation of the drive unit can be realized. An object of the present invention is to provide a fermentation decomposition treatment apparatus capable of reducing the impact given to a user by reducing the impact, reducing the deformation generated in the stirring section, and enduring long-term use.

[0009]

In order to achieve the above object, in the fermentation decomposition treatment apparatus according to the present invention, a stirrer for stirring the waste organic matter is installed in a treatment tank provided with an opening through which waste organic matter enters, A driving unit for driving the stirring unit is provided outside the processing tank, and a driving force is transmitted from a rotation shaft of the driving unit to a rotation shaft installed on a processing tank wall of the stirring unit. Then, the rotating shaft of the driving unit and the rotating shaft of the stirring unit are made common, a torque arm is interposed between the driving unit and the processing tank, one end of the torque arm is fixed to the driving unit, and the other end is Is supported in a processing tank.

[0010] It is also preferable to provide an oil seal in a support hole of the rotating shaft opened in the processing tank wall and use a rolling bearing for the bearing of the rotating shaft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the attached FIGS. FIG. 1 is a front view of a fermentation decomposition treatment apparatus to which the present invention is applied, FIG.
FIG. 3 is a right side view thereof. This fermentation decomposition treatment device 20
Also, the basic structure is the same as that of the conventional one, and it comprises a processing tank 21, an agitating unit 22 installed in the processing tank, and a driving unit 23 installed outside the processing tank. The processing tank 21 also has an upper wall as an upper lid 24, and an opening 25 for feces, an opening 26 for urine, an opening 27 for exhaust, and an opening 2 for taking out compost.
8 and the like, manure is introduced into the openings 25 and 26, and connection pipes 29, 30 and 31 for leading exhaust air from the opening 27 are respectively provided upright. Then, the toilet can be connected to the connection pipe 29, the urinal can be connected to the connection pipe 30, and the connection pipe 31 can be connected to a long exhaust pipe provided with an exhaust fan at the tip. Further, the compost take-out opening 28 is covered with a cover 33 with a handle.

In the upper lid 24, for example, a large number of, for example, 10 screwing locations are dispersedly arranged in the peripheral portion thereof, and the upper lid 24 is bolted to the upper edge of the peripheral wall of the main body of the processing tank 21.
Fix using. At this time, each bolt 3 placed at the four corners
In each case 4, the head 35 has a ring shape, and the processing tank 21 can be suspended and moved to facilitate installation. Further, since the mounting lid with handle 33 can be easily attached and detached, the opening 28 for taking out compost can be easily used as an inspection window inside the processing tank 21.

The basic structure of the stirring section 22 is the same as that of the conventional stirring section. A cylindrical pipe 37 is used at the center of the rotating shaft 36, and the center is divided into two parts along the axis 38 around the cylindrical pipe. Spiral band members 39 (39a, 39b)
And a number of support rods 40 for supporting the band members 39 at an equal distance from the axis 38. Then, both ends of the rotating shaft 36 are connected to the left and right side walls 41 (41a, 4a, 4a) of the processing tank 21.
1b) is inserted into the support hole provided at the center of each and installed. At this time, oil seals (not shown) are respectively provided on both support holes of the rotating shaft 36 formed in the left and right side walls 41 of the processing tank 21, and the bearings of the rotating shaft 36 are provided with rolling bearings 42 (42 a, 42 a).
Use b). The belt-shaped member 39 with respect to the rotation shaft 36
Are reversed on the left side and the right side.

A motor, for example, a gad motor that reduces the number of revolutions to 1200: 1, is used as the drive unit 23, and its rotation axis is shared with the rotation shaft 36 of the stirring unit 22. At this time, the size, material, and the like of each member used for the agitating section 22 are selected, and by increasing the processing accuracy, a rotating shaft 36 having less deformation such as twisting or bending is manufactured and used. A motor mounting plate 44 having a substantially equilateral triangular plate-shaped torque arm 43 interposed between the motor 23 and the processing tank 21 and having one end on the bottom side of the torque arm 43 disposed on the processing tank side of the motor 23.
Is fixed using two sets of bolts 45 and the like. In addition, a support hole is provided at one end on the vertex side of the torque arm 43, and a bolt 46 having no screw at the neck is loosely fitted into the support hole and fixed to the right side wall 41 b of the processing tank 21. Then, the torque arm 43 integrally connected to the motor 23 can be pivotally supported in the processing tank 21 so as to be slightly rotatable.

In this manner, the motor 23 and the stirring section 22
When the motor 23 is installed on the right side wall 41b of the processing tank 21 via the torque arm 43 or the like, the motor 23 can be brought close to the processing tank 21 and the fermentation decomposition processing apparatus 20 can be made compact. it can. Therefore, it is easy to install the fermentation decomposition treatment device 20 even in a narrow place. The motor 23 is protected by covering its head with an upper closed cylindrical cover 47 fixed to the center of the right edge of the upper lid 24.

Such a fermentation decomposition apparatus 20 requires control of a motor 23 for driving the stirring section 22 and a heater (not shown) for heating at low temperature in winter or the like. Therefore, a controller (not shown) is installed, for example, near the toilet, and the operation is set at the start of use or during use. Then, it is possible to arbitrarily set the start time, the operation time, the rotation direction, etc. of the stirring section 22, the heating start time, the heating time, the heating temperature, and the like. Further, sawdust is taken from the feces opening 25 or the storage lid 33 through the toilet, and the sawdust is put into the processing tank 21 through the compost taking-out opening 28.

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 removed from a stirrer 22 driven by a motor 23, for example, three times a day. Stir for hours. 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 left and right directions so that the microorganisms are fermented. At this time, an 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 43 and transmitted to the processing tank 21.

Because one end of the torque arm 43 is fixed to the motor 23 and the other end is pivotally supported by the processing tank 21, the motor 23 is mounted on the torque arm 43 supported at one point of the processing tank 21. It is rotatable around one end,
This is because the motor 23 can be slightly rotated by the impact generated by the operation. In addition, since the motor 23 can rotate slightly during operation, the motor 23 and the agitating section 22 do not completely coincide with each other. An excessive force due to the rotation does not act on the rotating shaft 36 of the stirring section 22 or the like. Therefore, the deformation which obstructs the smooth rotation such that the cylindrical tube 37 forming the central portion of the rotating shaft 36 of the stirring section 22 is bent does not occur. In addition, since both the support holes of the rotating shaft 36 formed in the left and right side walls 41 of the processing tank 21 are provided with oil seals and the rolling bearings 42 are used, a part of the waste organic matter and compost does not leak outside from the support holes. , Rotating shaft 38
Keeps spinning smoothly.

In this way, when the shock generated by the start of the motor 23 is weakened and transmitted to the treatment tank 21, even a user who is unfamiliar with the toilet including the fermentation decomposition treatment device 20 suddenly transmits the shock to the toilet or the like. You will not be surprised by. Moreover, the interior of the toilet is always in communication with the inside of the processing tank 21, and air is drawn by the exhaust fan provided at the end of the exhaust pipe to create a negative pressure, so that the smell of feces and urine is immediately discharged. Becoming comfortable, the smell does not stay indoors. In the toilet including such a fermentation / decomposition treatment apparatus 20, the input of sawdust and the removal of compost are periodically performed, for example, every three months. The removed compost is easy to handle because it is smooth and does not stick, and can be effectively used as a compost or soil improvement material.

In the above embodiment, the fermentation decomposition processing apparatus 20 is used.
Is used as a toilet, but the fermentation / decomposition / treatment apparatus 20 can also be used as a garbage processing apparatus by slightly changing the details without changing the basic structure.

[0021]

According to the present invention described above, claim 1
In the described invention, the rotation axis of the drive unit and the rotation axis of the processing tank are made common, and the torque arm is interposed between the drive unit and the processing tank, whereby the apparatus can be made compact. Therefore, the device can be easily installed even in a narrow place. Then, one end of the torque arm is fixed to the driving unit, and the other end is pivotally supported by the processing tank, so that the driving unit slightly rotates around one end of the torque arm supported at one point of the processing tank. The shock generated by the operation of the drive unit can be absorbed by the torque arm, attenuated, and transmitted to the processing tank. Therefore, even a user unfamiliar with the apparatus is not surprised by the impact transmitted to the processing tank.

In addition, since the driving section is slightly rotatable around one end of the torque arm supported at one point of the processing tank, the rotation axes of the driving section and the stirring section do not completely coincide with each other. Nevertheless, the rotating shafts may be shared, and an excessive force due to the rotation of the driving unit does not act on the rotating shaft of the stirring unit. Therefore, no deformation occurs such that the rotating shaft of the stirring unit cannot rotate smoothly, and the device can withstand long-term use.

According to the second aspect of the present invention, an oil seal is provided in a support hole of a rotary shaft formed in a wall of a processing tank, and a rolling bearing is used as a bearing of the rotary shaft. The rotation shaft can be kept rotating smoothly without leaking to the outside from the support hole. For this reason, no excessive force acts on the rotating shaft of the agitating section or the like, and the deformation that prevents the rotating shaft from rotating smoothly does not occur any more, and the apparatus can withstand long-term use.
