Abstract

The axial flow type hammer crusher includes one crushing chamber with end plates and air inlet, one horizontal rotor inside the crushing chamber, and one sieving plate around the rotor. The rotor includes one main shaft, hammer frame plates with pin shaft, and hammer sheets mounted onto the pin shafts. Around the main shaft, there is one inside air channel including a casing coaxial with the main shaft, an air intake channel and air outlets. The crusher can produce radial wind to push small material grains to pass through the sieving plate, raising the efficiency of the crusher by over 20 %.

Description

Axial type hammer blade grinder
Technical field
The present invention relates to a kind of feed processing machinery, particularly a kind of beater disintegrating machine.
Background technology
At present, a kind of beater disintegrating machine that material is pulverized that is used for is arranged, mainly comprise pulverizing chamber, the pulverizing chamber two ends are provided with end plate, the end plate at two ends is provided with air inlet, pulverize indoor horizontal and be provided with rotor, the rotor periphery is provided with from the sieve sheet of bottom and both sides semi-surrounding rotor, described rotor comprises main shaft, some hammer frame plates and hammer leaf, hammer frame plate is provided with perpendicular to main-shaft axis and along the main shaft axially spaced-apart, hammer frame plate is provided with pin shaft hole, and bearing pin is installed in the pin shaft hole, and hammer leaf is sleeved on the bearing pin and has spacer to separate.During work, material is in pulverizing chamber, with the rotor generation multiple impact of high speed rotating, and in pulverizing chamber, make the high speed circular motion along the rotor direction of rotation, the short grained material of part can pass the discharging of sieve sheet, during discharging, can adopt the air draught of negative pressure air intake device, promote that material sieves.Its weak point is: when material is made the high speed circular motion, can form a materials flow layer along the compass screen surface rotation, this materials flow layer is called circulation layer, under centrifugal action, bulky grain in the material can accumulate in the circulation layer periphery under centrifugal action, and short grained material accumulates in the circulation layer inboard easily, and oarse-grained material stops that short grained material passes the sieve sheet, and pulverizer efficient is reduced; Simultaneously, because short grained material can not in time pass sieve aperture, cause it to clash into repeatedly with hammer leaf in pulverizing chamber, the not only waste of energy, and temperature of charge raises, and spontaneous combustion takes place easily, leads to a disaster; At this moment, air intake device produces negative pressure around the sieve sheet, but effectively supplies sieve, and also cause energy dissipation.Though this technical scheme has additional air inlet on the end plate of two ends, but a large amount of tests through us confirm, can only form the footpath aweather at the two ends of rotor from the natural wind of this air inlet, that is to say a small amount of circulation layer that can only influence the pulverizing chamber end from the air intake of this air inlet, and little to other position effects in the pulverizing chamber.
Summary of the invention
The object of the invention provides a kind of axial type hammer blade grinder, makes rotor when rotating at a high speed, can produce the footpath and aweather accelerate sieving of material.
The present invention seeks to realize like this: axial type hammer blade grinder, comprise pulverizing chamber, the pulverizing chamber two ends are provided with end plate, the end plate at two ends is provided with air inlet, pulverize indoor horizontal and be provided with rotor, the rotor periphery is provided with from the sieve sheet of bottom and both sides semi-surrounding rotor, described rotor comprises main shaft, some hammer frame plates and hammer leaf, described hammer frame plate is provided with perpendicular to main-shaft axis and along the main shaft axially spaced-apart, hammer frame plate is provided with pin shaft hole, bearing pin is installed in the pin shaft hole, hammer leaf is sleeved on the bearing pin, in the main shaft outside and pin shaft hole one inner air channel is set between the revolution inside circumference of main shaft, and described inner air channel comprises between the adjacent hammer frame plate sleeve pipe with the coaxial setting of main shaft, the hammer frame plate of sleeve pipe inboard is provided with the air intake passage that is connected with air inlet on the end plate of pulverizing chamber two ends, and described sleeve pipe circumferential surface is provided with some air outlets.
During this pulverizer work, rotor rotation is repeatedly hit pulverizing with the material that enters in the pulverizing chamber, and material is made the high speed circular motion in pulverizing chamber, forms a circulation layer along the compass screen surface rotation naturally; Simultaneously, extraneous natural wind is entered by the air inlet of pulverizing chamber two ends end plate, and by blowing to each position of pulverizing chamber respectively with inboard air channel, inside that is provided with of pin shaft hole and the air outlet on the middle sleeve of inner air channel in the main shaft outside, destroy original circulation layer in the pulverizing chamber, allow to screened material under the effect of wind-force, promptly pass sieve aperture.This technical scheme technical pattern is simple, and processing and fabricating is convenient, the equipment security of operation, and the reliability height can also be saved the equipment and materials cost simultaneously.This technical scheme has obtained obvious effects through the several times test, under the situation that does not dispose the negative pressure air intake device, and also discharging smoothly, under the situation of configuration negative pressure air intake device, its material sieves more smooth; Compared with prior art, the energy consumption of negative pressure air intake device reduces knows clearly more than 70%, and production efficiency improves more than 20%, has saved the energy consumption of feed factory greatly.
As optimization of the present invention, described hammer leaf end is along sleeve pipe insertion portion or all in the air outlet, the air outlet that is inserted with hammer leaf is along the curved setting of sleeve pipe circumferencial direction radially.Compared with prior art, this technical scheme can be saved over the use of beater disintegrating machine inner spacing collar, reduced when changing hammer leaf requirement to operating personnel, the hammer leaf easy accessibility, accurate positioning is quick, in addition, and when adopting the pulverizer work of this technical scheme, distance between the arc air outlet can be adjusted according to the design needs, just can change the gap between the hammer leaf.The air outlet air-out that hammer leaf aweather can be never inserted in the footpath also can be from the gap air-out between hammer leaf and the air outlet.
