Description

The hammer leaf type drum sieve pulverizer

Technical field

The utility model belongs to size reduction machinery, particularly a kind of hammer leaf type drum sieve pulverizer that is applicable to fields such as grain, feed, chemical industry.

Background technology

At present, hammer slice type band sieve pulverizer is one of most widely used mill type in producing, the shape of its sieve sheet has cylinder type, droplet-shaped, inferior ellipse, the U type, Ω type etc., above-mentioned several sieve sheet all is fixed or vibrates within the specific limits, its weak point is that they only are suitable for coarse crushing, for the broken weak effect of micro mist, reason is that underproof large granular materials can't be discharged and accelerated motion after hammer leaf hits in pulverizer comminuting matter process, because action of centrifugal force makes material break away from the strike of hammer leaf, and it is very fast at the inboard material ring that forms of sieve, the quality difference of thickness material, cause the layering of material ring, coarse-particle bed is near sieve sheet side, and the fines granulosa overlays on the coarse fodder granulosa, forms circulation layer.Under the situation of the circulation layer that can't destroy material, not only influence the coarse granule material and return to and pulverize the district, and influence qualified particle and sieve.Especially carrying out micro mist when broken, hammer sieve gap and sieve aperture are less, and the rotor speed height, material is by the sieve plate difficulty, increased the frictional heat of material and sieve plate, temperature of charge is raise, and noise is big, the power loss of motor, also cause the excessive pulverizing of material in pulverizing chamber simultaneously, pulverizer sieves scarce capacity, just has the stifled sieve of serious circulation layer inevitably, makes crush efficiency low.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of running route that can change comminuting matter is provided, and destroys the material circulation layer, and effectively sheet is sieved in cleaning, improves the hammer leaf type drum sieve pulverizer of crush efficiency.

The technical scheme that the utility model technical solution problem adopts is: the hammer leaf type drum sieve pulverizer is by base, put on the shelf, main motor, shaft coupling one, crusher housing, pulverizer main shaft, rotor, hammer leaf, stock guide is formed, be characterized in lower end in crusher housing, the rotary screen housing is housed, at rotary screen housing right-hand member the rotary screen motor is housed, motor shaft connects the rotary screen main shaft with shaft coupling two, adorn a rotary type rotary screen sieve sheet on the rotary screen spindle end, in rotary screen sieve sheet, a plurality of pressure-air jet pipes are housed, establish several pressure-air spray orifices on the pressure-air jet pipe periphery, one end of pressure-air jet pipe is communicated with the high-voltage pulse device, on rotary screen sieve sheet excircle, fix several parabolic plates, below rotary screen housing left side, be provided with the rotary screen discharging opening.

The beneficial effects of the utility model are: when the material after the pulverizing contacts with the rotary screen compass screen surface, qualified granule passes sieve aperture, underproof coarse granule is after turning over certain angle, be thrown into the pulverizing district by roller screen device centrifugal force, again pulverize, material circulation layer running route is changed, destroyed circulation layer, the pressure-air jet pipe intermittently sprays pressure-air, compass screen surface is kept clean, the compass screen surface of clearing up rotate again with pulverize after material contact, the work compass screen surface of making remains efficiently the sieve ability that falls, and has equaled to increase effective sieve of several times area that falls, and makes the original sieve sheet of pulverizer improve the sieve ability that falls, improve crush efficiency, guaranteed the quality of comminuting matter.
