Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a vacuum transport device for garbage with a crusher.

(B) Prior Art A conventional vacuum transportation device with a crusher will be explained with reference to FIG. 11 is a garbage input port, and garbage inputted from the garbage input port 1' is stored in a storage tank 2', is crushed by a crusher 31, falls down a hopper 51, and enters a transport pipe 7'. The suction force of the blower 121 transports it to the separator 11. Note that 4' is a motor for driving the crusher, 9 is an air intake valve for transportation, 61 is a discharge valve for airtightly shutting off other equipment during transportation, and B+ is a machine room pit.

As more and more air is taken in through the air intake valve 91,
The negative pressure within the transport pipe 71 is not propagated near the input port 110. The type of crusher 3I is a pair of parallel shafts that rotate in opposite directions, a rotary blade installed coaxially, and a two-axis rotary shearer that crushes the transported material by meshing the rotary blades. Type crushers are often used. There is currently no valid format other than this one.

Considering future technological development, the crusher is not limited to a two-axis rotating shear type. Crushing and collection of garbage will be carried out sequentially for each garbage input and storage facility.

Therefore, when one set of air intake valve 91 and exhaust valve 6I is open, the other air intake valve and exhaust valve are closed. This means that garbage from open areas is being collected. When garbage collection in the input storage tank is completed, the valve is closed, and the valve of the secondary input storage tank is opened to collect garbage in sequence. Transport and crushing are carried out at the same time, and the crushed waste is sent to the transport pipe 71 through the hopper 5' without being stored. The Proa 1211 separator 111 is installed and remotely controlled by the collection center. Automatic and manual remote control are common.

Conventional garbage vacuum transportation equipment with a crusher has the following drawbacks. Two valves, an exhaust valve 61 and an air intake valve 9', are provided.
It was getting complicated. Hopper 5' was sometimes clogged with garbage. Kitchen waste and heavy objects were accumulated at the T-shaped portion where it joins the transport pipe 71, causing a blockage.

(C) Problems to be Solved by the Invention This invention has a structure that prevents garbage clogging in a part of the hopper and accumulation of garbage in the T-shaped part where it joins the transport pipe, and also simplifies the structure and reduces the cost. The purpose is to measure costs.

B) Means for Solving the Problems An embodiment of the present invention implemented as a garbage vacuum transport device with a crusher will be described below with reference to the drawings.

Fig. 2 is a schematic diagram of an embodiment of the garbage vacuum transportation device with a crusher of the present invention, Fig. 5 (1) is a schematic cross-sectional view of its air intake port, and (2) is a view taken along the arrow A-A of (ri). figure.

FIG. 4 shows a schematic sectional view of another embodiment of the air intake, and FIG. 5 shows a schematic view of the hopper.

1 is a garbage input port, 2 is a storage tank, and 3 is a crusher.

4 is a crusher driving motor, 5 is a hopper, 6 is a part, 14 is a guide plate, 15 is an air volume adjustment plate, 16 is a lattice-shaped opening, 17
19 shows an air amount adjusting grid, and 19 shows an air amount adjusting plate. The air adjustment means 15°17.19 is attached with bolts, nuts, etc.

It can be installed to adjust the opening amount of the air vent with a long or large one. Air conditioning is adjusted and fixed at the beginning of plant operation (during trial run). There is almost no need to make any adjustments after that.

In the present invention, the conventional air intake valve 91 shown in FIG. 1 is eliminated, and an air intake port 10 is provided in the hopper 5 as shown in FIG. 2.

(e) Effect The air intake port 10 has a structure that prevents dirt from coming out.

An example of the air intake port 10 is shown in FIG. air intake 10
A guide plate 14 prevents dust from coming out from the openings 13 and 15, and an air amount adjustment plate 15 adjusts the amount of suction air.
It consists of The air amount adjusting plate 15 may be omitted.

FIG. 4 shows an example of another structure of the air intake port 10. Hopper 5 is a hopper with rounded corners, with the upper crusher connection part being rectangular and the lower part being circular. A grid-shaped opening 16 is provided in the hopper 5 to prevent dust from coming out, and an air amount adjustment grid 17 is provided to adjust the amount of opening of the opening 16 and adjust the amount of suction air. The air amount adjusting plate 17 may be omitted. In FIG. 5, the upper part of the hopper 5 is made larger than the fall area of the waste from the crusher 3, and an opening is provided between it and the crusher section. 19
is an air adjustment plate that adjusts the opening, is a flat square plate, and can be attached to the hopper by bolts or nuts or other methods, and adjusts the amount of suction air. This air adjustment plate 19
may be omitted.

(f) Effects of the Invention The present invention achieves the following 92-order effects in addition to the above configuration.

(1) No need for air intake (electric pulp).

The system becomes simple. The air adjustment plate will be fixed after adjustment.

(2) Air enters the hopper, eliminating clogging of the hopper.

(3) Since the junction with the transport pipe is a bend pipe, there is no blockage caused by accumulation in the conventional T-shaped pipe.
