Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the cutaway view that level was broken up ultrafine crusher in the utility model divided.
As seen from Figure 1, the utility model is ganged up by internal classification pin-type load ultrafine grinding device 1 and internal classification vortex ultrafine grinding device 2 and is constituted.Internal classification pin-type load ultrafine grinding device 1 body inner chamber is cylindrical, impact type grating disk 8 is divided into two parts up and down with it, the bottom is made up of grading wheel vee-pulley 7, grating disk vee-pulley 6, rectangle Flow-rate adjustment butterfly valve 3 and deslagging screw 4, be provided with crushing tooth cover 10 with the corresponding body inwall of impact type grating disk, impact type grating disk 8 is provided with two circle impact poles, also is provided with high velocity jet impeller 9 on it.Top is made up of the self-conveyor feed on flow splitter 11, cage grading wheel 12 and the sidewall 5, and charger 5 passes through motor-driven.Flow splitter 11 is separated into pulverizing chamber and grading room with internal classification pin-type load ultrafine grinding device 1 again.Impact type grating disk 8 and cage grading wheel 12 are driven separately by motor through vee-pulley 6,7 respectively by two concentric shafts.Grading wheel can obtain requiring rotating speed through changing corresponding vee-pulley 7, thereby obtains the fineness of required product.Internal classification vortex ultrafine grinding device 2 is a gas tool air-sweeping type pulverizer, vee-pulley 20 is arranged at the top, handle 21 is adjusted in the vortex classification, the exit that material is discharged spiral case 22 is provided with ultra-fine material discharge blower fan 19, make the ultra-fine material of gas one solid phase enter cyclone collector and cloth bag gatherer smoothly, be convenient to the layout of production technology, this machine inner air consumption is increased, have refrigerating function, be applicable to the processing heat sensitive material.Be divided into two pulverizing chamber by second section classification rotating vane 15a in this device, first pulverizing chamber is made up of centre bearing 13, first section volution blade 17a, vortex chamber tooth cover 14, impacting pin lining 16, second pulverizing chamber is made up of second section volution blade 17b, classfied cone fixed cover 18, classification rotating vane 15b, classification rotating vane 15a, b promptly are conspicuous according to checking the mark grade blade, second section volution blade 17b is bigger than first section volution blade 17a, and the blade twist angle is also big.The gap length on volution blade 15a, b and classfied cone fixed cover 18 end inclined-planes, decision is conspicuous according to grade function and the crushing effect again of checking the mark, the vortex classification is adjusted handle 21 and is utilized pad just can transfer three kinds gaps, inclined-plane such as 1,2,3, to satisfy the requirement of product and fineness selection.
Referring to Fig. 1 operation principle is described: material joins the pulverizing chamber of internal classification pin-type load ultrafine grinding device 1 by self-conveyor feed 5 and quantitative and even, enter on the grating disk 8 that two circle impact pole high speed rotaries are installed when material, pass through action of centrifugal force, at a high speed to crushing tooth cover 10 repeatedly bounce-back collision back and forth, smash into fine powder, wherein meal is thrown to the bottom, because the air draught function that there is the axial screw chip architecture at grating disk 8 centers and sprays impeller 9, a large amount of high-speed airs are inhaled into the inner chamber that sprays impeller 9 through rectangle butterfly valve 3 with the coarse granule material, the coarse granule material are got rid of once more carry out once more fine powder to impact pole and crushing tooth cover 10 broken at a high speed.Rectangle butterfly valve 3 can be regulated the throughput that enters pulverizing chamber, to change the product that classifying turbine obtains different fineness.Difficult hard material of pulverizing and impurity are by outside the deslagging screw 4 discharge machines in the material, fine powder is transported to the top grading room through ascending air, and the fine powder that meets fineness requirement is sent to the 2 further dark ultra-fine grindings of internal classification whirlpool formula ultrafine grinding device through cage grading wheel 12.Defective fine powder returns to pulverizing chamber through flow splitter 11 and carries out once more, repeatedly pulverizes.First pulverizing chamber of fine powder in centre bearing 13 enters internal classification vortex ultrafine grinding device 2 of coming from the bottom carried out ultra-fine grinding by first section volution blade 15a, because volution blade has certain torsion angle, helps to form the rotation blast.Second section classification rotating vane 17a do not have torsion angle, can form gas-flow resistance, causes the air-flow circulation in first pulverizing chamber because the blast of first section volution blade 15a formation makes like this.Along with impacting mutually, collide, rub, shear between the material of air-flow rotation, the particle, and be subjected to action of centrifugal force rush at inwall vortex chamber tooth overlap 14 and impacting pin lining 16 be subjected to effects such as bump, friction, shearing and be ground into superfine powder repeatedly.Also more effectively pulverize in the inclined-plane of second section classification rotating vane 17a end and the gap between classfied cone fixed cover 18 conical surfaces, but the most effective pulverization is stagnant area between first and second section volution blade 15a, b, because the high speed of volution blade rotation, material is stirred sharp, forces to pulverize, impacts mutually, rubs, shears by ultra-fine grinding.Classification is to be discharged from the air-flow suction that blower fan 19 produced between the centrifugal force that produced by second section classification rotating vane 17a and the classfied cone fixed cover 18 to decide, if the centrifugal action that particle is subjected to is greater than air-flow suction, particle continues to stay and pulverized so.If the centrifugal action that particle is subjected to is less than air-flow suction, particle just is attracted to the center and enters second pulverizing chamber with air-flow, and the big I of air-flow suction meets the requirements of the classification powder particle size by the adjusting of the rectangle butterfly valve 3 of bottom.Fine particle enters second pulverizing chamber and is also similarly pulverized repeatedly and classification.Because the volution blade 15b of second pulverizing chamber is bigger than preceding, and the blade twist angle is also big, so the blast that causes is bigger, the mutual impulsive force between the particle is also bigger, and therefore, crushing effect and grading function all increase enhancing.Superfine powder outside discharging blower fan 19 discharge machines, capture, screening and product.
