Next, the operation of the waste disposal apparatus according to the present invention will be described. When processing waste discharged from a medical site or the like, first, the closed lid 2 of the autoclave A is removed, and the waste is put into the sterilization chamber 11 (the waste storage container 3).
After closing the sterilization chamber 11 with the sealing lid 2, the operation panel section 13 is operated. First, the sterilization chamber 11 is evacuated by the decompression means, the waste is dried, and the like. By heating and pressurizing 11, the waste in the sterilization chamber 11 is sterilized. During this sterilization treatment, the pressure inside the sterilization chamber 11 was adjusted to about 1.5 kg / cm ² and the temperature inside the sterilization chamber 11 was adjusted from 100 to 129 ° C., and this was maintained for several tens of minutes, thereby adhering to the waste. It is possible to completely kill pathogens living in blood, body fluids, and the like.

When the sterilization is completed, the sealing lid 2 is removed, and the waste sterilized by the transporting means H is crushed.
Send to filling means G. That is, when the transport unit H is started by operating the operation panel unit H1, the operation panel unit H1 is started.
The control means stored in the control section operates the transport means H as follows.

Next, the motor M2 rotates in the direction opposite to the direction in which the holding means 1 is lowered, and raises the holding means 1 holding the waste storage container 3. At this time, the holding means 1
(See FIG. 4).
Thereby, the waste storage container 3 is carried out from the sterilization chamber 11 of the autoclave A as shown in FIG. Then, the holding means 1 holding the waste storage container 3 is configured as shown in FIG.
As shown in (c), it is inclined along the shape of the belt B, and the tip of the waste transfer means 8 remains in that state.
That is, the crushing / filling means G moves upwardly of the waste input port 4a.

The holding means 1 having moved to the tip of the waste transfer means 8 follows the shape of the folded portion formed on the belt B by the second roller R2 (see FIG. 4) provided on the upper part of the belt B. Then, as shown in FIG. 6 (d), the waste container 3 is turned upside down and turned upside down. When the waste container 3 is inverted, the motor M2 is stopped, and the waste container 3 is stopped at the position in the inverted state for a predetermined time. Thus, the waste stored in the waste storage container 3 is crushed and filled by the crushing / filling means G.
To the waste input port 4a. When the waste falls, the dissipation prevention cover 20 crushes the waste from the waste storage container 3 into the waste input port 4 of the crushing and filling means G.
Since waste can be guided to a, waste does not fall outside the apparatus.

Then, after the input of the waste into the crushing / filling means G is completed, the motor M2 changes the rotation direction of the belt B to move the waste storage container 3 into the autoclave A as shown in FIG. It moves into the sterilization room 11. Next, the solenoid 1c is turned off and the inner plate 1b is
And the holding means 1 releases the waste storage container 3. Thereafter, the motor M2 rotates so as to raise the holding means 1 again, raises the holding means 1 to the standby position shown in FIG.

Is sent to a pair of rotating bladed rollers 5a,
After being caught in 5a and crushed to a predetermined size, it passes through the crushing mechanism 5 and falls from the crushing mechanism 5 below the hopper 4. The size of the waste crushed by the crushing mechanism 5 can be adjusted by changing the distance between the rotating shafts 5b and 5b that support the bladed rollers 5a and 5a. It is desirable to crush the syringe or used ampule into small pieces so as not to damage the body. In addition, while the waste is crushed by the crushing mechanism 5, the autoclave A may sterilize other waste (the next waste).

On the other hand, the waste crushed to a predetermined size by the crushing mechanism 5 is temporarily stored in the hopper 4. That is, the waste logistics outlet 4 of the hopper 4
Since b is closed by the elevating member 7b of the compressing means 7 as described above, the waste is temporarily stored in the hopper 4. The waste stored in the hopper 4 is heated and dried by the drying means 10 described above. When the amount of waste in the hopper 4 reaches a predetermined amount, the sensor 7c installed in the hopper 4 outputs a signal to the compression unit 7, and the compression unit 7 starts operating.

FIG. 7 is a diagram showing the operation of the compression means 7. Next, the operation of the compression means 7 will be described with reference to the drawings. As shown in FIG. 7A, when the amount of waste in the hopper 4 reaches a predetermined amount, the sensor 7c outputs a signal to the cylinder 7a. When a signal is sent from the sensor 7c, the cylinder 7a raises the elevating member 7b, and opens the waste distribution outlet 4b of the hopper 4. (Refer to FIG. 2B.) As a result, the waste in the hopper 4 is discharged to the waste distribution outlet 4
b, and falls into the bag X held in the open state by the storage device support member C. Then, after a lapse of a predetermined time, the cylinder 7a lowers the elevating member 7b to compress the waste falling into the bag X. (See (c) in the figure)

As a result, the waste is filled in the bag without forming an X space or the like. The lifting member 7
When the b is lowered, the lifting member 7b can open the waste distribution outlet 4b of the hopper 4 as shown in FIG. When the compression of the waste is completed, the cylinder 7a raises the elevating member 7b to a fixed position and stops, and waits until a signal is sent from the sensor 7c. The compression means 7 can compress and fill the bag X with the crushed waste to a predetermined size by repeating this operation several times. Then, when the elevating member 7b does not descend to the predetermined position during the compression of the waste, the compression means F reports to the worker that the filling of the bag X with the waste is completed by a buzzer (not shown). It has become. Then, the worker attaches the storage device supporting member C to the rail 6.
b, the bag is moved to the vicinity of the opening / closing outlet 9 of the isolation room D, and the bag X filled with waste is taken out from the opening / closing outlet 9 and disposed of like ordinary waste.

The waste treated by the waste treatment apparatus is sterilized by the autoclave A, so that there is no risk of infection. The waste is crushed by a crushing mechanism 5 until it reaches a predetermined size, further dried by a waste volume reducing means F, and the bag X
