BRIEF DESCRIPTION OF THE DRAWINGS FIG. First, a conventional waste treatment apparatus will be described. 9th, 1st
In FIG. 0, (1) shows a waste treatment apparatus, and the treatment apparatus (1) mounts a fermenter (3) having an input port (3a) on an upper part of a gantry (2). In the center of 3), a stirring claw shaft (4) is mounted on a bearing (4a), and a plurality of stirring claws (5) are attached to the stirring claw shaft. The stirring claw (5) is configured as a tuck-shaped claw with a curved tip. A cutting blade protrudes from the tip of the rotation locus of the stirring claw (5). The cutting blade and the stirring claw (5) are fed into the fermentation tank (3) through the input port (3a) by joint work. It is designed to break up the garbage that is produced.

Further, on the side surface of the fermenter (3), a control part (6) containing a drive motor (7) for rotating the stirring claw shaft (4), an air blower for supplying hot air to the fermenter (3), and the like. ), And drives the input sprocket (9) of the stirring pawl shaft (4) via the chain (10) from the output shaft (7a) of the motor (7) disposed below the casing (6a). It is supposed to. An air supply blower (8) is housed in the casing (6a), and a heater for heating air supplied to the fermenter (3) in the middle of the hot air pipe (11) from the blower (8). (12) is provided, and the end of the hot air pipe (11) is extended to the bottom of the fermenter (3) to constitute a hot air supply device. The fermenter (3) is divided into left and right sides by a partition wall (13), and the hot air tube (11) is branched off from the middle according to the partition and arranged at the bottom of each fermenter. (14) shows two branched hot air pipes branched from a hot air pipe (11) disposed in the center of the ceiling in the fermenter (3), and the tip of each of the branched hot air pipes (14) and (14). An outlet (11a) is provided in the section.

Further, an exhaust blower (16) disposed in a casing (6a) is connected to one end of an exhaust duct (15) having a plurality of air inlets (15a) at the ceiling of the fermenter (3). ing. The exhaust blower port (16a) is connected to an exhaust pipe (18) outside the casing (6a) via an exhaust connection pipe (17). And the exhaust blower (16)
The air in the fermenter tank (3) is sucked from the exhaust duct (15) suction port communicating with the blower (16) by the operation of the blower (16), and the air in the fermenter tank (3) sucked by the exhaust blower (16) is blown by the blower (16). ) Passes through the exhaust connection pipe (17) and is forcibly discharged to the outside air from the exhaust pipe (18).
(19) is a communication pipe connecting the casing (6a) and the fermenter (3), and the casing (6) is forcibly discharged from the fermenter (3) by the exhaust blower (16).
The hot air in a) is supplied to the fermenter.

In addition, an inlet cover (20) is attached to the inlet (3a) provided in the upper part of the fermenter (3) so as to be openable and closable. There is a lid (21).

In the above-mentioned waste treatment apparatus, a drive motor (7) for rotating the stirring claw shaft (4), an air blower for supplying hot air to the fermenter (3) and the like are housed in a casing (6a). ing. Therefore, it is necessary to provide a control box called a casing (6a), and each device is housed in the casing (6a) without being inexpensive. Therefore, when one device is repaired, another device hinders maintenance. However, when repairing electrical components during maintenance, the drive train may be activated and endangered. In addition, since the control box is disposed outside the fermenter main body, when the waste disposal apparatus is installed outdoors, there is a possibility that each device is exposed to feng shui. The present invention improves this. That is, as shown in FIG. 1, the outer shape of the fermenter is formed in a T-shape, and a drive system of a stirring claw shaft, a drive motor thereof, an air blower of a hot air supply device are provided in a space below the T-shaped overhang, Each of the electrical equipment such as a heater and a switch is arranged. The one shown is the left overhang (23) of the fermenter (22).
A space (24) is formed below the bottom of the fermenter, and a drive system is housed therein, and a space (26) is formed below the right overhang (25) of the fermenter. It contains electrical equipment. The fermentation treatment apparatus configured as described above is more specifically configured as follows. That is, the shaft (28) of the stirring claw (27) is mounted on the left and right bearings (29a) and (29b) at the center of the fermentation tank main body, and the stirring claw (27) is provided in each of the left and right fermentation tanks. Installed.

As shown in FIGS. 1 and 2, the drive system housed in the left space (24) is further recessed from the left space (24) toward the center of the main body and from the rear to the front. Driven by a drive motor (31) housed in a cave (30) that bites into the hole, the large gear (3) of the intermediate shaft (34) meshing with the small gear (33) of the drive shaft (32).
5) is driven by a drive motor, and the large sprocket (38) is further driven from the small sprocket (36) of the intermediate shaft (34) via the chain (37), and the stirring pawl shaft (28)
Is driven. Therefore, the agitating claw shaft (28) is driven by the drive motor (31) in two-step shifting. In the drawing, (39) indicates a stay connecting the axis (34) and the axis (28).

Next, the electric equipment housed in the right space (26) houses an air blower (40) as shown in FIG. 5, and the heater (41) is passed through an outlet (41) through a flexible tube (42). (4
Air is introduced into the inlet (44) of 3), the air is heated by the heater (43), and the air is heated from the outlet (45) of the heater (43) to the bottom of the stirring tank body (22) through the air inlet (46). The air is guided to the horizontally provided nozzle pipe (47), and hot air is blown out from the nozzle port (48) to promote fermentation of the processed product with aerobic microorganisms. And the fermenter (2
In the front of the main body of 2), there is a lid (49) for taking out the processed material.

FIGS. 6, 7 and 8 show the upper body of the fermenter, wherein the top surface (51) of the upper body (50) of the fermenter is provided with a downward inclination toward the front, and a horizontal hem opening is provided. Edge (5
2) is fitted on the rim (53) of the fermenter tank body (22) as shown in FIG. In the center of the top surface (51) of the upper body (50) of the fermenter, a control box (54) is formed and has a built-in control device, and has a removable lid (55) for maintenance. On the left and right sides of the control box (54), there are lids (56) and (56) which can be opened and closed for charging the processed material into the left and right fermenters. A metal fitting (57) for supporting the lid (56) is attached to one of the rims (58) of the processed material input port (57), and a skirt (59) of the lid (56) is attached to the pin (61). ) To open and close freely. A proximity switch (62) for detecting opening and closing of the lid is provided at the other edge (58) opposite to the pin hinge.

The fermenter upper body (50) has a discharge hole (63) for deodorizing the odor generated in the fermenter and discharging it to the outside. A deodorizer equipped with a deodorizing tank and an exhaust fan is attached to the discharge hole (63). In any case, the present invention forms the outer shape of the fermenter (22) in a T-shape,
The space (24) (2) below the character-shaped overhangs (23) (25)
The gist of the invention is that a driving system for the agitating claw shaft and its driving motor, and electric equipment such as an air blower, a heater, and a switch of the hot air supply device are arranged in 6).

[0014]

According to the present invention, the outer shape of the fermenter is formed in a T-shape, and the respective equipments can be dispersed and arranged in the space below the left and right T-shaped overhangs. The equipment is easy to maintain without being disturbed by other equipment.
In addition, there is no need to provide a control box unlike the conventional one, so that the structure can be made simple and easy, and since the devices are arranged in the space below the overhang, the waterproof property against rain or the like is improved.
