Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage storage and discharge device that temporarily stores municipal waste thrown into a chute and discharges it intermittently.

Garbage collected from households can be temporarily stored, and once it has accumulated to a certain extent, it can be discharged into a vacuum transport line and transported to a waste treatment facility, or it can be stored to be loaded onto a garbage truck and transported. Ejector is used. Conventional garbage storage and discharge devices are generally of the rotating drum type with screw blades fixed to the inner circumferential surface for transporting garbage.When storing garbage, the exit outlet is closed and the drum is rotated using the propulsive force of the screw blades. The waste is stored, and when the garbage is to be discharged, the discharge port is opened and the drum is rotated to push out the garbage using the screw blades. However, once a certain amount of dirt accumulates in the rotating drum, the propelling action of the screw blades is almost eliminated, and a large amount of dirt cannot be stored, resulting in an increased size of the device and problems in that it is not able to be discharged smoothly. For this reason, some systems have installed an auger inside the smooth drum to compress and store a large amount of waste, but in this case, the strings in the municipal waste become tangled with the shift, making maintenance difficult and reducing the amount of waste. There were problems such as the need for selective input.

This invention was made in view of the above-mentioned circumstances, and its purpose is to provide a garbage storage and discharge device that can store and discharge a large amount of garbage and is free from maintenance problems. It is.

An embodiment of the present invention will be described above with reference to the drawings.

In the figure, 1 is a cylindrical storage tank that is arranged and fixed horizontally, and the lower end of the garbage input chute 2 is connected to the inlet side of this storage tank 1, and the outlet side casing 3 is fixed to the outlet outlet. An opening/closing lid body 5 is provided which is moved back and forth by a cylinder 4. A detector 6 is attached to the upper part of the garbage input chute 2 to detect the amount of garbage accumulated in the chute 2. Reference numeral 7 denotes a spiral blade formed by winding a band plate in a spiral shape with a winding diameter that matches the inner diameter of the storage tank 1, and its both ends are fixed to rotating rings 9 and 10 provided at the front and rear ends of the storage tank 1. It is rotatably fitted inside the storage tank 1. Further, scraping plates 8 are radially attached to the outer circumferential surface of the spiral blade 7 at appropriate intervals to have the function of maintaining the shape of the spiral blade 7 and promoting the feeding of the dirt. Furthermore, longitudinal grooves 11, 1 are formed at appropriate intervals on the inner circumferential wall of the storage tank 1.
1 is provided to prevent dust from rotating together with the spiral blade 7 and to improve the transport of dust. The rotating rings 9 and 10 are annular bodies with a convex cross section, and the outlet side ring 1
0 is rotatably supported by a bearing 1a at the end of the storage tank 1 and an annular bearing 14 integral with the outlet casing 3, and the inlet ring 9 is also rotatably supported by an annular bearing (not shown) integral with the inlet side plate 13. and is supported by the end bearing portion of the storage tank 1 in the same manner as the outlet side. The rotary rings 9 and 10 are rotated by a drive mechanism 15 from the outside of the storage tank 1, so that the input garbage is transferred toward the lid 5 by the spiral blades 7.
This drive mechanism 15 includes a shaft 17 that is rotationally driven via a sprocket wheel 16 by a motor with a speed reducer (not shown), and sprocket wheels 18, 18 that are pivotally attached to both ends of the shaft 17.
and sprocket rings 19, 19 fixed to the outer peripheries of rotating rings 9, 10 which are rotated in conjunction with the sprocket wheels 18, 18 through a chain.
The rotating rings 9 and 10 are configured to rotate in synchronization with each other. A gate valve 21 is provided between the vacuum transport line 22 and the outlet side casing 3, and is opened and closed by a cylinder 23.

When storing garbage in the storage tank 1, the outlet outlet of the storage tank 1 is closed with the lid body 5, and the detector 6 detects when the garbage has accumulated in the feeder 2.
The dust is detected and the spiral blade 7 is rotated to transfer the dust in the direction of the lid body 5. This operation is repeated several times to compress and store the waste in the storage tank 1. When a predetermined amount of garbage is stored in the storage tank 1, to discharge the stored garbage, activate the vacuum suction system, open the gate valve 21, and move the lid 5 to open the outlet outlet of the storage tank 1. By rotating the spiral blade 7 after opening, the stored garbage is transferred continuously and quantitatively to the transport line 2.
2 and transported to a waste treatment facility (not shown). In addition, if a resilient wire brush is attached to the outer peripheral edge of the spiral blade 7, the inner peripheral wall of the storage tank 1 and the inside of the groove 11 can be cleaned to prevent dust from adhering and remaining. Furthermore, although the above embodiment has been described with respect to the case where the storage tank 1 is connected to a vacuum transport line, it can also be applied to the case where the storage tank 1 is loaded onto a garbage collection truck.

The garbage storage device of the present invention is as described above and has a configuration in which the spirally wound spiral blades are rotated from outside the storage tank, so it compresses the garbage in the same way as the conventional screw-auger type. Since there is no shaft in the storage tank, there is no problem of strings getting tangled.
