Abstract
The invention discloses an air channel crushing device of a coal crusher. The air channel crushing device of the coal crusher comprises an octagonal sheet-type fixing main body, wherein a fixing sleeve is arranged in the middle of the fixing main body and comprises a hollow sleeve main body; a pair of penetrated locking through holes is formed in the top of the sleeve main body; and an outwards extending wing cutter part is arranged on each of eight edges of the fixing main body. By the air channel crushing device of the coal crusher, the fixing main body arranged in an air channel and the wing cutter parts arranged on the eight edges of the fixing main body are directly used; on one hand, the wing cutter parts can generate partial air volumes, and the air pressure in the air channel can be increased, so that the flow speed of coal dust is increased; on the other hand, the wing cutter parts can crush large particles in the coal dust again, so that the coal dust crushing efficiency is improved. The air channel crushing device of the coal crusher is simple in structure, convenient to mount and low in use cost.
Description
Technical field
The present invention relates to a kind of coal mining equipment, or rather, is a kind of air channel breaker of coal crushing machine.
Background technology
Coal crushing machine another name also is the twin-stage disintegrating machine, belongs to efficient equipment in small, broken bits, mainly for the pulverizing problem of coal, according to the actual needs coal is refined into coal particles or coal powder, and the recycling air duct is transferred to coal dust in the storage warehouse.Because the water content of raw coal coal dust is larger, the flow velocity in the air channel is slower, if improve transfer efficiency, then must adopt powerful exhaust equipment, and cost is higher, also needs more electric power.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of air channel breaker of coal crushing machine is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of air channel breaker of coal crushing machine, the air channel breaker of described coal crushing machine comprises the stationary body of an octagonal sheet, the middle part of described stationary body is provided with a fixed muffle, described fixed muffle comprises the sleeve body of a hollow, the top of described sleeve body is provided with a pair of locking through hole that runs through, and is respectively equipped with a wing fence section of outwards stretching on eight edges of described stationary body.
As preferred embodiment of the present invention, described wing fence section comprises one first kink and one second kink, and the angle of described the first kink and the second kink is 120 °.
As preferred embodiment of the present invention, the edge of described the second kink is provided with sawtooth.
The air channel breaker utilization of coal crushing machine of the present invention is set directly at the wing fence section on eight edges of stationary body in the air channel and this stationary body, on the one hand, these wing fence sections can produce local wind rate, increase the blast in the air channel, improve the flow velocity of coal dust, on the other hand, wing fence section can carry out again the bulky grain in the coal dust broken, further improves the crushing efficiency of coal dust.The air channel breaker of this coal crushing machine is simple in structure, easy for installation, and use cost is cheap.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
As shown in Figures 1 to 4, the air channel breaker 1 of coal crushing machine of the present invention comprises the stationary body 2 of an octagonal sheet, the middle part of this stationary body 2 is provided with a fixed muffle 3, this fixed muffle 3 comprises the sleeve body 31 of a hollow, the top of this sleeve body 31 is provided with a pair of locking through hole 32 that runs through, and is respectively equipped with a wing fence section 4 of outwards stretching on eight edges of this stationary body 2.
The angle that this wing fence section 4 comprises one first kink 41 and one second kink, 42, the first kinks 41 and the second kink 42 is 120 °.
The edge of the second kink 42 is provided with sawtooth.
The above be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
