Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blast removing device for a crushing device that discharges a blast generated by explosive combustion of combustible gas or the like contained in waste in the crushing device to the outside of the crushing device.
[0002]
[Prior art]
Conventionally, waste that is crushed by a crushing device contains gas cylinders and paint cans that contain flammable gas, so that when the waste is crushed, the ignition of the waste is the gas. This ignites and explodes and burns, and a blast is generated in the crusher. The blast spreads into the discharge cover that covers the discharge port of the crusher and the conveyor cover that covers the carry-out conveyor. There is an adverse effect of deforming and damaging a thin-walled material (compared to a crushing container of a crusher).
[0003]
In view of this, there has already been proposed one in which a blast door is provided on the wall of the cover, and when the blast is generated, the blast is released to the outside by opening the blast door (Japanese Patent Laid-Open No. Sho 56-121646). reference).
[0004]
[Problems to be solved by the invention]
However, the conventional blast door is damaged and broken every time it receives a blast, and it is difficult to reuse the blast door. In addition, it takes time and effort to repair the blast door. There is a problem of shortening the length and causing a reduction in crushing efficiency.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a new crushing device blast eliminator capable of solving the above problems.

A square blast port 30 is opened, and a bone member 31 having a vent 32 is fixed to the blast port 30 over the entire surface.
[0019]
The bone member 31 is formed of a mesh, for example, a wire mesh, in which vertical bars 31 ₁ and horizontal bars 32 ₂ are assembled in a lattice shape, and has rigidity that does not deform even when subjected to a blast. A mounting frame 33 is fixed to the outside of the wall surface of the discharge port cover 16 so as to border the blast port 30, and the softness that covers the blast port 30 between the mounting frame 33 and the wall surface of the discharge port cover 16. The periphery of the cover plate 34 made of a rubber plate is attached. A plurality of arbitrary points in the middle of the cover plate 34, wire passing through the vent 32 of the bone members 31, cord, by the locking member 35, such as a hook piece, engaging the bone member 31 to the scan pop preparative shape Stopped. Thus, the locking member 35 has a physical property that can be broken by receiving a blast.
[0020]
Next, the operation of this embodiment will be described. First, waste, that is, the material to be crushed is introduced into the crushing drum 1 from the inlet 10 by the carry-in conveyor 13, and the electric motor 7 in the crushing drum 1. Crushing is performed by hitting with the rotating hammers 6 group. The waste after the crushing process is discharged to the outside from the discharge port 16 through the discharge port cover 16 and the conveyor cover 17 by the carry-out conveyor 18.
[0021]
By the way, during the waste crushing process, combustible gas remaining in gas cylinders and paint cans ignited by the ignition of the waste during crushing process and explode and burned. In addition, a blast is generated in the crusher C, and the blast spreads from the crushing drum 1 to the discharge port cover 16 and further to the conveyor cover 17 and acts on the blast eliminator E provided on the wall surfaces thereof. Then, as shown in FIG. 4, the blast breaks the plurality of locking members 35 or the flexible lid plate 34 that locks the lid plate 34 to the bone member 31. It is possible to release from the bone member 31 and open the blast opening 30 to release the blast to the atmosphere. Thereby, it is possible to prevent the wall surfaces of the discharge port cover 16 and the conveyor cover 17 (thinner than the wall surface of the crushing drum) from being deformed by the blast pressure.
[0022]
In addition, even if a negative pressure is generated in the crushing apparatus during the crushing process, the lid plate 34 is supported by the outer surface of the bone member 31, so that the lid plate 34 is not recessed.
[0023]
Next, a second embodiment of the present invention will be described with reference to FIG. 5. FIG. 5 is a partially broken rear view of the blast eliminator, and the same members as those in the first embodiment are the same. A code is attached.
[0024]
In the second embodiment, the structure of the bone member is different from that of the first embodiment, but the other configurations are the same as those of the first embodiment.
[0025]
Metallic bone member 131 is constituted by fixing a transverse bar 131 and _second ends of the plurality of which are parallel in parallel with each other in the vertical bar 131 ₁ of the left and right, a rubber cover plate to each bar 131 ₂ 34 is locked by the locking member 35.
[0026]
Thus, the bone member 131 also has a function equivalent to that of the bone member 31 of the first embodiment.
[0027]
Next, a third embodiment of the present invention will be described with reference to FIG. 6. FIG. 6 is a partially broken rear view of the blast eliminator, and the same members as those in the first embodiment are the same. A code is attached.
[0028]
In the third embodiment, the structure of the bone member is different from that of the first embodiment, but the other configurations are the same as those of the first embodiment.
[0029]
The metal bone member 231 is formed by opening a number of punches 231 ₂ in a punching metal, that is, a metal plate 231 ₁ .
[0030]
Thus, the bone member 231 also has the same function as the bone member 31 of the first embodiment.
[0031]
The blast blasting device E may also be provided on the wall surface of the inlet cover 11.
[0032]
Although the first to third embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various embodiments are possible within the scope of the present invention.
[0033]
For example, the bone member may be composed of another effective material such as a perforated plate or a porous body instead of a wire mesh, a rod, or a punching metal, and the lid plate may be a synthetic resin plate or the like instead of a rubber plate. In addition, the locking member may be composed of another effective material such as a wire, a string, a thread instead of a scratched portion, or a blast opening. May be formed in other shapes such as a circle instead of a square.
