Description

DETAILED DESCRIPTION OF THE INVENTION This invention/i: In a garbage processing device that uses a conveyor device to throw garbage that has been collected into a garbage storage 1 into a crusher, and then crushes the garbage, This invention relates to a blast cutoff device that prevents generated blast waves from flowing toward the bit side.

Conventional garbage processing equipment is a crusher...Is there a loading locator at the top?
The communication port on the side of the input locoper has a structure that exposes the tip of the dust storage bit and the conveyor device at the bottom, and the communication port is especially large to allow the garbage to pass through smoothly.
It is open.

However, the crushed garbage contains flammable gases such as gas cylinders and paint cans. It may explode. As a result, the blast generated by the explosion passed through the large communication port and blew away the workers working above the bit, and the debris blown away by the blast caused damage to vehicles above the pit. Therefore, there was a risk of injury to workers. , 9 The present invention solves the above-mentioned problems by providing a communication port! Covering board? The shield plate is provided so that the communication port is opened wide when garbage is thrown in, and closed when a blast occurs.

An example will be explained below with reference to the drawings.This is an IH: a tight-type crusher for crushing garbage, and the crusher (1) is located in a building (21
Inner KI! It is attached. The upper part of the crusher (1) is provided with an inlet force <-+31 to cover the inlet, and the inlet locator 13) is designed to prevent the dust from scattering to the surroundings. Introducing Lokanoku again - (3)
The side of the building (21) is fitted into the opening (4) on the side and has a communication port (5); A platform (8) is formed above the bit (6) for the storage bit (6) and a platform (8) for the operator to work on. ), and put the garbage in the bit (6) into the crusher (1) using the conveyor @ (7).
It has become so.

(9) is a sorting machine, etc.
This is a conveyor for conveying C, and the base end is located below the crusher (1).

u... is the input port force, = -+31, 'Building (
The openings in the ceiling of 21 are located at the entrance to the port...
... is closed from above by the safety cover (11)..., and the blast wave generated by the explosion inside the crusher (1)... It is now possible to press 12 to open and exit the building (2) with a force of λ.

Next, to explain the blast shielding bag MIF, (12 is a shielding plate divided into a plurality of parts suspended from an opening (4) on the side of the building (2), and the middle part of the shielding plate (12 is an opening). (4)
The upper part is attached to the outside of the side of the building (2) via a bracket αJ [2] so that it can swing back and forth, the lower part closes the communication port (5), and the upper part is attached to the side of the building 121. The forward swing is restricted by contacting the buffer member (14). At this point, remove the bit (6) of the shielding plate az.
) When a force is applied to the lower part of the side, the shielding plate α2 is swung as shown by the dashed line in FIG.
5) is opened to a large degree, and the opening height h is increased as shown by the solid line in Figure 2 during normal operation or when force is applied to the lower part of the crusher (1) side.
is small, and the communication port (5) is substantially closed.

The present invention has the above-mentioned structure, and its operation will be explained next.-F/
- First, the garbage collected by a garbage truck or the like is put into the bit (6) from the platform (8).

(beep) 161 K has been added, and the garbage is conveyed to the conveyor device (
At 7), it is transferred to the rJi side and put into the crusher (1).
Ru. At that time, the communication port (5) is closed by the shielding plate 11z, and the passing debris passes through the shielding plate C1z as shown in Fig. 2-a.
Iff of the Fli line] <Since it is pushed up at the height H-f, it is possible to smoothly charge the garbage into the crusher (1). Especially since the shield plate (1z is divided into multiple parts) Shielding plate 1 in the necessary position even for light specific gravity dust
You can only push up 3 and pass.

After the droplets are crushed by the crusher (1), they are discharged from the F side of the crusher (1) to the north of the conveyor (9), where they are transported to the conveyor (9). Transferred to a sorting machine, etc.

Next, if the flammable gas remaining in the crusher (1) explodes, the blast generated by the explosion will flow to the input port and the input port cover 13, and the safety lid (11) of the ceiling opening (101)
1'f1-press [7 opening is the ceiling opening of building (2)]
The O1 safety lid (11) was also pushed open, and the Akatsuki bombed building 121.
It flows outside and enters so as not to damage the shredder (1) and the building (21). At that time, the blast wave also tries to flow out from the communication port (5) on the bit (6) side G, but the blast wave Shielding plate (1
Since it acts on the lower part of the crusher (1) side of 21, the shielding plate 1
121 or held in the solid line position in Figure 2 with tongues 1 and 41.
The flow of the blast toward the h1 pit (6) side where the opening height h of the m port (5) is small is restricted. A shielding plate is installed at the opening, and when the garbage passes through the communication port to the crusher side, the shielding plate is swung to open the communication port to a large angle A, so that the bomb on the crusher side closes the communication port. As a result, the T/R blast blows away the workers on the platform without interfering with the work of putting the garbage into the crusher, and the debris blown away by the blast is removed from the platform. It is possible to eliminate dangers such as damaging the shaft and injuring the worker.

[Brief explanation of the drawing]

FIG. 1 is an overall view, FIG. 2 is a partially enlarged view, and FIG. 3 is a sectional view taken along line AA in FIG. (1) is the crusher, 13) is the input port cover, (5) is the communication port, (6) is the garbage storage pit), +71 is the conveyor device,
+121 is a shielding plate.

Claims (1)

[Claims] In a garbage processing device, an input port cover is provided on the upper part of the crusher, and a communication port is provided on the side of the input port cover (IC layer, the tip of the conveyor device at the bottom of the garbage storage pit is exposed). A garbage processing device characterized in that a shielding plate to be closed is swingably hung only on the crusher side, and the shielding plate prevents the blast generated in the crusher from flowing to the bit side. Explosion and lice blocking device.
