Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is used in the field of crushing waste, particularly in the field of finely crushing fluorescent lamps and the like.

(b) Conventional technology In a conventional crusher, a crushing blade having protrusions on the outer periphery is fixed to a rotating drum at appropriate intervals, and a chute is provided to guide the material to be crushed toward the rotating drum. It had a structure with a cutout groove for the crushing blade to pass through.

However, with the above structure, the crushing effect is exerted only when the object to be crushed passes through the notched grooves, so the crushing efficiency is poor and it is difficult to crush fluorescent lamps and the like into fine pieces.

(c) Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks by providing a fixed blade on the chute facing the rotating drum so as to overlap with the crushing blade of the rotating drum, and further A protrusion is provided on the side of the blade.

(d) Means for Solving Problems The present invention provides a rotating drum in a casing having an input chute at the top and a discharge port at the bottom, and crushing blades having protrusions on the outer periphery are installed at appropriate intervals on the rotating drum. A plurality of fixed blades are provided and fixed, and a chute extending toward the rotating drum is provided at a position opposite to the rotating drum, and a plurality of fixed blades erected at appropriate intervals are superimposed on the crushing blade in the chute. The present invention relates to a crusher in which a plurality of protrusions are provided on the side surface of the fixed blade to regulate a gap between the fixed blade and the crushing blade.

(e) Example An example will be described below with reference to the drawings. Reference numeral 1 is a crusher for finely crushing fluorescent lamps, etc. Above the crusher 1, an inclined input chute 2 is provided. A crank hammer 3 for pretreatment is provided opposite the input chute 2.

A discharge port 4 and a blowout port 5 facing each other are provided below the crusher 1, and the discharge port 4 and the blowout port 5
is communicated with a blower 8 via a suction pipe 6 and a discharge pipe 7, so that air is recycled as a whole.

The crusher 1 has a casing 9 as shown in FIG.
A rotary drum 10 is rotatably provided inside the rotary drum 10, and a plurality of disc-shaped crushing blades 11 are fixed to the outer periphery of the rotary drum 10 at appropriate intervals.

A plurality of protrusions 12 are provided on the outer periphery of the crushing blades 11 to facilitate pulling in of objects to be crushed.

A chute 13 for guiding the material to be crushed toward the rotary drum 10 is provided at a position facing the rotary drum 10, and a plurality of fixed blades 14 erected on the chute 13 at appropriate intervals are connected to the crushing blades. 11... is provided by polymerizing it.

A crushing blade 11 is provided on the side surface of the fixed blade 14.
A plurality of protrusions 15 are provided to the extent that they do not come into contact with the side surfaces.

The fixed blade 14 has an auxiliary chute 1 at its upper end.
6, and the end of this auxiliary chute 16 is provided with a notch 17 through which the crushing blade 11 can pass,
The object to be crushed is configured to pass through the cutout portions 17.

18 is a cyclone. 19 is a drum. 20 is a trolley.

The present invention has the above-mentioned structure, and its operation will be explained next.
When the material to be crushed is thrown in, the material to be crushed is coarsely crushed by the crank hammer 3 and then finely crushed by the crusher 1.

The finely crushed material is passed from the discharge port 4 to the suction pipe 6.
After being sucked into the blower 8 through the cyclone 18
The materials to be crushed are stored in a drum can 19.

The air discharged from the blower 8 is sent to the discharge pipe 7.
It is guided to a discharge port 5 opposite to the discharge port 4. At that time, the material to be crushed roughly crushed by the crank arm 3 is guided to the rotary drum 10 side by the chute 13 and the auxiliary chute 16, and the protrusions 1 of the crushing blades 11...
2..., is crushed when passing through the notch 17..., and is further crushed into fine pieces between the projections 15... and the crushing blades 11....

(f) Effect of the invention As described above, the present invention provides a rotating drum with a crushing blade with projections, a chute facing the rotating drum, a fixed blade on the chute, and a plurality of projections on the side surface of the fixed blade. With this arrangement, the object to be crushed drawn in by the projection of the crushing blade can be reliably crushed into fine pieces between the crushing blade and the projection.
