Description
Technical field
The utility model relates to a kind of pulverizer, particularly a kind of novel beater disintegrating machine.Beater disintegrating machine of the present utility model is widely used in material grinding in the industries such as feed, grain, food, chemical industry, medicine, agricultural chemicals, metallurgy, belongs to the pulverizing technical field of processing equipment.
Background technology
Beater disintegrating machine is under the drive of power master motor, main shaft by the rotor that is connected with main motor rotates, the hammer leaf that drives rotor is along with main shaft rotates together, the material that enters into the inner chamber of pulverizing chamber from charging aperture is pulverized under the effect of hammer leaf and sieve plate, the material after the pulverizing by behind the sieve plate punishment in advance from discharge hole for discharge.Existing beater disintegrating machine exists following defective: (1) crush efficiency is low, and sieve plate easily stops up.This is because existing beater disintegrating machine is when using, all be under negative pressure state, to work under the centrifugal blower effect, material will realize that punishment in advance mainly is subjected to the effect of two aspect power from the inner chamber of the pulverizing chamber sieve plate of scurrying out: the one, and be subjected to high speed hammer leaf bump and bring centrifugal force, be the attraction that centrifugal blower provides wind on the other hand, have only when attraction greater than centrifugal force and the frictional force material sieve plate of just scurrying out.Be not more than 13% material through impurity elimination, moisture and pass through feeder, feed in the pulverizing inner chamber of pulverizing chamber with stable, uniform flow rate full duration, in the inner chamber of pulverizing chamber, material is through high-speed impact, the shearing of hammer leaf, small particles material after crashing flies to sieve plate at a high speed and clashes into, clash into again with sieve plate then, thereby the granule raw material is further pulverized, at the same time, between material and hammer leaf, material and sieve sheet, material and the material mutual friction mutually, collision taking place also, thereby obtains thinner particle; The material of low speed is drawn in by hammer leaf after with at a high speed hammer leaf violent bump taking place first, can be enhanced terminal linear velocity near hammer leaf in a short period of time at this particle speed, and makes circular motion with hammer leaf.And in the inner chamber of pulverizing chamber, form the material circulation layer gradually, the perpendicular formation of the direction of the sieve plate of scurrying out under the effect of the direction of motion of this circulation layer and material wind-force, be unfavorable for the material sieve plate of scurrying out, therefore the material sieve plate ability of in time scurrying out, crush efficiency is low, sieve plate easily stops up, and more is prone to blockage problem for the small-bore sieve plate especially, and crush efficiency is lower; (2) use cost height, consumable accessory mounting or dismounting trouble.Present beater disintegrating machine because the sieve plate obstruction seriously can't be used and must often change sieve plate, causes the increase of use cost on the one hand; Because the axial location part that hammer leaf is fixed on the bearing pin does not have compatibility, need mate correspondence during mounting or dismounting on the other hand, therefore install and remove the hammer leaf trouble, waste time and energy, the mounting or dismounting time is long, and bearing pin is stressed big, the service life of bearing pin is short, and the replacement cycle is short, and this has also increased use cost greatly.Therefore solving the sieve plate obstruction is very urgent problem, also is an insoluble always technical barrier.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that the sieve plate punishment in advance is smooth and easy, sieve plate is difficult for stopping up, improving crush efficiency, cost performance height, simple load and unload a kind of novel beater disintegrating machine.
Realize that the above-mentioned purpose technical scheme is: a kind of novel beater disintegrating machine, include support, casing, main motor, shaft coupling, rotor, sieve plate, pressure screen frame (unit), sieve plate gripper shoe, side plate and secondary pulverizing chamber, also comprise pulverizing chamber, casing is provided with charging aperture, support is provided with discharging opening, the secondary pulverizing chamber is positioned at the bottom of pulverizing chamber, rotor includes main shaft, hammer frame plate, bearing pin, coupling spindle and hammer leaf, main motor is connected with the main shaft of rotor by shaft coupling, also includes the sieve plate exciting device.
Further, described sieve plate exciting device is a pulsed sieve plate exciting device, and the sieve plate exciting device includes gas bag, impulse electromagnetic valve and high-pressure nozzle, and high-pressure nozzle is provided with spray orifice, gas bag is connected with high-pressure nozzle by impulse electromagnetic valve, and high-pressure nozzle is positioned at the sieve plate outside; Perhaps the sieve plate exciting device is rotation shaft type sieve plate exciting device, the sieve plate exciting device includes exciting variable-frequency motor, adapter sleeve, rotating shaft, ball and connecting rod, the exciting variable-frequency motor is connected with rotating shaft by adapter sleeve, rotating shaft is provided with connecting rod, connecting rod is provided with ball, and connecting rod is positioned at the sieve plate outside.
Further, rotor also includes swivel nut, and hammer leaf is arranged on the bearing pin by swivel nut.
Further, described spray orifice is relative with sieve plate; Perhaps described ball is relative with sieve plate.
After adopting technique scheme, have a lot of benefits: (1) sieve plate punishment in advance is smooth and easy, sieve plate is difficult for stopping up, the crush efficiency height.The utility model is provided with the sieve plate exciting device, sieve plate played splendid beat, the vibration effect, can clear up the sieve aperture that stops up on the sieve plate timely and effectively on the one hand, destroyed the circulation layer of material on the other hand, this makes that the sieve plate punishment in advance is smooth and easy, is difficult for stopping up, improved crush efficiency, the crush efficiency height has increased output; And adopt pulsed sieve plate exciting device or rotation shaft type exciting device, can control sieve plate exciting force size by regulating air pressure or variable-frequency motor, the time of exciting also can be regulated, and has realized intermittently instantaneously giving power to sieve plate, and cleaning is more controlled opportunity, make the ability of cleaning sieve plate bigger, cleaning sieve plate effect is better, even for very easily stifled small-bore sieve plate, cleaning effect is also very good, the sieve plate punishment in advance is also very smooth and easy, and sieve plate is difficult for stopping up; (2) cost is low, the cost performance height, and mounting or dismounting are convenient.The lower cost of one side the utility model, not only solved the susceptible to plugging problem of sieve plate, avoided often to change the cost increase that causes because of sieve plate stops up to use, meanwhile, also sieve plate has been played good maintaining effect, made consumable accessory sieve plate long service life, changed number of times and significantly reduce, reduced the consumption of sieve plate, the use cost of sieve plate is reduced greatly; On the other hand because the setting of swivel nut, make that hammer leaf is carried out the swivel nut of axial location is identical, can wildcard, do not need to mate correspondence during mounting or dismounting, therefore realized the quick mounting or dismounting of hammer leaf, made mounting or dismounting simple to operate, it is time saving and energy saving to install and remove, the mounting or dismounting time is short, and because the setting of swivel nut, make that bearing pin is stressed to be reduced, improved the service life of bearing pin greatly, prolong bearing pin the replacement cycle, reduced the use cost of bearing pin.These all make use cost of the present utility model reduce greatly, and cost performance is very high.
