Abstract
The utility model discloses an air-channel breaking device of a coal breaking machine. The air-channel breaking device comprises an octagonal and piece-shaped fixed main body, wherein a fixed sleeve is arranged at the middle part of the fixed main body; the fixed sleeve comprises a hollow sleeve main body; a pair of penetrative locking through holes are formed on the top of the sleeve main body; and the eight edges of the fixed main body are respectively provided with a winged cutter part extending outwards. The air-channel breaking device disclosed by the utility model has the advantages that by utilization of the fixed main body directly arranged in the air channel and the winged cutter parts on the eight edges of the fixed main body, on the one hand, the winged cutter parts can generate local air quantity so as to increase the air pressure in the air channel and improve the flowing speed of coal powder; on the other hand, the winged cutter parts can break large particles in the coal powder again so as to further improve the breaking efficiency of the coal powder; and the structure is simple, the installation is convenient and the use cost is low.
Description
Technical field
The utility model 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, is primarily aimed at 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 bigger, 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 utility model mainly is to solve the existing in prior technology technical problem, thereby a kind of air channel breaker of coal crushing machine is provided.
Above-mentioned technical problem of the present utility model 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 portion of outwards stretching on eight edges of described stationary body.
As the utility model preferred embodiment, described wing fence portion comprises one first kink and one second kink, and the angle of described first kink and second kink is 120 °.
As the utility model preferred embodiment, the edge of described second kink is provided with sawtooth.
The air channel breaker utilization of coal crushing machine of the present utility model is set directly at the wing fence portion on eight edges of stationary body in the air channel and this stationary body, on the one hand, these wing fence portions can produce local air quantity, increase the blast in the air channel, improve the flow velocity of coal dust, on the other hand, wing fence portion can carry out again broken to the bulky grain in the coal dust, 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 preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figures 1 to 4, the air channel breaker 1 of coal crushing machine of the present utility model 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 portion 4 of outwards stretching on eight edges of this stationary body 2.
The angle that this wing fence portion 4 comprises one first kink 41 and one second kink, 42, the first kinks 41 and second kink 42 is 120 °.
The edge of second kink 42 is provided with sawtooth.
The above only is the specific embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
