Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is applicable to a crusher, particularly in the field of circulating air between a crusher and a blower and discharging waste after crushing with the air. It is something that will be done.

(b) Conventional technology In conventional shredding machines, especially those that shred fluorescent lamps, etc., and which transport the shredded waste by air, it is necessary to prevent harmful substances from being released into the atmosphere after shredding. Therefore, exhaust air is circulated between the crusher and the blower. However, in the above structure, the amount of air at the outlet through which waste from the shredder passes is approximately equal to the amount of air at the outlet opposite the outlet, so the amount of waste at the outlet is However, the problem was that the air returned to the crusher side, and the air generated turbulence just before the outlet, preventing the waste from flowing smoothly to the outlet.

(c) Problems to be solved by the invention The present invention solves the above-mentioned problems.
A part of the air supplied from the blower to the blow-off pipe is made to flow into a branch pipe branched from the blow-off pipe, so that the amount of air at the blow-off port is smaller than the amount of air at the discharge port.

(d) Means for Solving the Problems The present invention provides a crusher having an input chute at the top, and a discharge port and a blow-off port opposite to the discharge port are provided at the bottom of the crusher, and the discharge port includes a blower extending from a blower. A suction pipe is communicated with the outlet, and a discharge pipe extending from the blower is communicated with the outlet, and a part of the outlet pipe is arranged such that the amount of air passing through the outlet is smaller than the amount of air passing through the outlet. This invention relates to a crushing device provided with a branch pipe.

(e) Example An example will be described below with reference to the drawings. Reference numeral 1 denotes a crusher, and a crank arm 2 for rough crushing is swingably provided above the crusher 1. The input chute 3 is provided in an inclined manner.

Below the crusher 1, there is a discharge port 4 and a blowout port 5.
are provided facing each other, and the discharge port 4 is connected to a blow-off pipe 8.
The blower port 5 is connected to the blower 7 via a blower pipe 8, so that air from the blower 7 can be circulated through both pipes 6 and 8.

The blower 7 is provided with a cyclone 9, and the waste separated by the cyclone 9 is transferred to a drum can 10.
It is now being accommodated in

A separator 11 is interposed in a part of the blow-off pipe 8, and when the air from the blow-off pipe 8 passes through the separator 11, harmful substances such as mercury are removed.

A branch pipe 12 is branched by a part of the separator 11, and the branch pipe 12 is installed along the input chute 3 and communicates with an auxiliary passage 13 formed within the input chute 3.

An input port 14 is formed at the tip of the input chute 3, and this input port 14 extends into the crusher 1 through an input passage 15.

An indicator 16 for detecting a closed state of the blowing pipe 6 is provided near the input port 14.

The display device 16 includes a transparent case 17 and a case 1.
The case 17 is installed so as to communicate with the auxiliary passage 13. As a result, when the blowing pipe 6 is blocked and the air pressure in the blowing pipe 8 is reduced, the air pressure in the branch pipe 12 and case 17 is also reduced, causing the ball 18 in the case 17 to descend, thereby detecting the blocked state. can do.

Reference numeral 19 denotes a communication passage provided in the input chute 3 that communicates the auxiliary passage 13 and the input passage 15. The communication passage 19 guides air from the auxiliary passage 13 to the input passage 15 to remove dust in the input passage 15. It is guided to the crusher 1 side to prevent dust from scattering from the input port 14.

20 is a cart on which the crusher 1 is mounted. In the embodiment, the branch pipe is guided to the input chute, but the structure is not necessarily limited to this, and the same effect can be obtained even if the branch pipe is made to face the crusher or blowing pipe. . The present invention has the above-mentioned structure, and the operation will be explained next. When waste is inputted from the input port 14, the waste passes through the input passage 15 and is coarsely crushed by the crank arm 2, and is then crushed by the crusher 1. Shredded into small pieces. The finely crushed waste is led from the discharge port 4 through the blowing pipe 6 to the blower 7 side, separated by the cyclone 9, and then stored in a drum can 10.

The separated air passes through the blowout pipe 8 to the blowout port 5.
is supplied to

At this time, the amount of air supplied from the blower 7 to the blow-off pipe 8 partially flows to the branch pipe 12 side, so the amount of air passing through the blow-off port 5 is the amount of air passing through the discharge port 4, that is, the amount of air that is sucked into the blower 7. Since the amount is smaller than that of the waste, turbulence does not occur immediately before the outlet 4, and the air from the outlet 5 flows smoothly to the outlet 4 together with the waste.

(f) Effects of the Invention As described above, the present invention provides a branch pipe from a part of the blow-off pipe so that the amount of air passing through the blow-off port is smaller than the amount of air passing through the discharge port, which prevents the problem from occurring in the past. This eliminates turbulent flow just before the discharge port, allowing waste to be discharged smoothly.
