Description
Technical field
The present invention relates to a kind of horizontal positive pressure grinder, it belongs to hammer type crushing device.It, in the process using hammering crushing material, provides the air of certain pressure in pulverizing chamber, improves crushing effect.It is applicable to pulverize the material such as grain, feed.
Background technology
In prior art, there is a kind of horizontal pulverizer, mainly comprise by end plate, the pulverizing chamber that side plate closes, the top of pulverizing chamber is provided with charging aperture, rotor is provided with in pulverizing chamber, rotor is fixed on horizontal spindle, main shaft is through two ends version, and be fixed on by the rolling bearing units at two ends on support, the top of pulverizing chamber is provided with charging aperture, bottom is provided with discharging opening, sieve plate is in the outside of rotor, bend to the shape can wrapping up rotor, therefore discharging opening and pulverizing chamber are kept apart by sieve plate, during the work of this pulverizer, discharging opening is ined succession suction air device, mair motor rotor driven rotates, bulky grain from charging aperture is ground into by the rotor run up can through the granule of screen cloth, through the granule of screen cloth under the effect of extractor fan, discharge from discharging opening, simultaneously due to the centrifugal motion of material, the large granular materials that quality is large is easily assembled and blocks screen cloth outside screen cloth, make fine material can not discharge screen cloth in time, thus circulation layer is formed in the certain limit of rotor, particle just operates and can not readily pass through screen cloth in this circulation layer, this reduces the efficiency of pulverizer.
For destroying circulation layer, improve crush efficiency, people utilize the subnormal ambient in pulverizing chamber, adopt the mode opening wind-supplying mouth on the biside plate of pulverizer, as: Chinese patent application publication number CN1669658A discloses a kind of horizontal pulverizer, utilize the wind-supplying mouth offered, make pulverizing chamber can suck a small amount of air from external environment condition, destroy circulation layer.This measure not obvious to the destruction of circulation layer, still fundamentally can not destroy circulation layer, and the existence of wind-supplying mouth makes sieve plate inside and outside differential pressure diminish.Affect the operating efficiency of suction air device, owing to being subject to the impact of these factors, the efficiency of pulverizer is still affected.
Summary of the invention
The object of the invention is for deficiency of the prior art, a kind of horizontal positive pressure grinder is provided, its object is to: initiatively improve the pressure in pulverizing chamber, destroy circulation layer, improve crushing effect.
For achieving the above object, the present invention is by the following technical solutions: a kind of horizontal positive pressure grinder, includes end plate and side plate, end plate and side plate affixed become pulverizing chamber, pulverizing chamber top is provided with charging aperture, pulverizing chamber bottom is provided with discharging opening, and main shaft two ends are through end plate, and the rotor being positioned at pulverizing chamber is fixed on main shaft, sieve plate is provided with outside rotor, also be provided with blower fan and airduct, the air outlet of airduct one end and blower fan is affixed, and the other end of airduct is communicated with the pulverizing chamber inside described sieve plate.
Further, the described airduct other end is communicated with pulverizing chamber by bottom sieve plate.
Further, be also provided with the air uniform plate being with some mesh, air uniform plate is between described pulverizing chamber and airduct.
Further, described airduct is the airduct of the rounded or rectangle in cross section.
Adopt the beneficial effect after technique scheme:
1, by blower fan and airduct directly to the air providing certain pressure in pulverizing chamber, change the subnormal ambient of pulverizing chamber, circulation layer in pulverizing chamber is destroyed owing to being subject to constantly perturbing of air, thus makes little particle easily through screen cloth, thus improves crush efficiency.In addition, due to the effect of blower fan, make tiny particle also easily be blown sieve plate, improve crush efficiency.
2, blower fan provides the air of certain pressure bottom sieve plate by airduct, and air discharges pulverizer in a counter-current fashion, improves the contact probability of air and material, improves crush efficiency.
3, the design of air uniform plate, makes air pass air uniform plate and is blown into pulverizing chamber, just can define an air curtain like this at pulverizing chamber width, improves crush efficiency by the air curtain formed.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
Embodiment
As shown in Figures 1 to 3, a kind of horizontal positive pressure grinder, it comprises main shaft 1, end plate 2, side plate 3, sieve plate 4, rotor 6, blower fan 9 and airduct 11, end plate 2 and side plate 3 affixed become pulverizing chamber 13, pulverizing chamber top is provided with charging aperture 7, pulverizing chamber bottom is provided with discharging opening 8, main shaft 1 two ends are passed end plate 2 and are fixed on pulverizing device frame 5 by bearing, the clutch end of main shaft one end and motor is affixed, rotor 6 is provided with some hammer leaves, rotor 6 is positioned at pulverizing chamber and rotor 6 is fixed on main shaft 1, sieve plate 4 is provided with outside rotor 6, the air outlet of blower fan 9 is connected with airduct 11 one end, the other end of airduct 11 is communicated with the pulverizing chamber 13 inside sieve plate.
During normal work, material enters pulverizing chamber by charging aperture, and the material after pulverizing passes sieve plate and discharges pulverizing chamber by discharging opening.Blower fan provides the air of certain pressure in pulverizing chamber by airduct, this measure changes the subnormal ambient of pulverizing chamber, circulation layer in pulverizing chamber is destroyed owing to being subject to constantly perturbing of air, thus makes little particle easily through screen cloth, thus improves crush efficiency.In addition, due to the effect of blower fan, make tiny particle also easily be blown sieve plate, improve crush efficiency.
For improving crush efficiency, inventor proposes further on the basis of preceding solution: the technical scheme of air inversion.Its concrete measure: aforementioned airduct 11 other end is communicated with pulverizing chamber 13 by 4-1 bottom sieve plate.So, the air of certain pressure enters pulverizing chamber from the position bottom sieve plate, and discharges pulverizer in a counter-current fashion, improves the contact probability of air and material, improves crush efficiency.
For making the air-distribution entering pulverizing chamber more reasonable, inventor proposes further on the basis of preceding solution: set up air uniform plate 12, this air uniform plate 12 is between aforementioned pulverizing chamber 13 and airduct 11.Certainly, air uniform plate 12 is provided with some mesh.When air is by air uniform plate, reticulate perforation plate can play even wind effect, makes air just can define an air curtain at pulverizing chamber width, improves crush efficiency by the air curtain formed.
Certainly, aperture needs, through calculating, to make large granular materials be unlikely to fall airduct and block air channel, little material is under the effect of air blast and extractor fan, in fluid boiling state and under air uniform plate can not be fallen, be namely have a little falling on air uniform plate, also again pulverizing chamber can be blown into.
Another: the cross section circular of aforesaid airduct 11 or rectangle.Pulverizer external energy is according to needing to establish suction air device.
The invention is not restricted to above-described embodiment, the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the scope of protection of present invention.
