Description
Technical Field
[0001] This utility model relates to the technical field of vertical mill classifiers, and in particular to a novel vertical mill classifier. Background Technology
[0002] The air classifier is a component of the vertical mill separator used for air classification. Its working principle is that there is a high-speed rotating rotor inside, which uses the principle of centrifugal force to screen the materials ground by the vertical mill.
[0003] The existing raw material grinding process is as follows: limestone, magnesium slag, silica powder, converter slag, shale, and coal-fired furnace slag are proportioned and fed into the raw material mill via belt conveyor for grinding at a rate of 80-90 tons per hour. The overall moisture content of the material entering the mill is 5-15%. The finished material after grinding (1% residue on a 200µm sieve) is mixed with dry calcium carbide slag powder (80-100 tons / hour of dry calcium carbide slag powder, 5%-10% residue on a 200µm sieve). The mixed material is then fed into a homogenization silo via an elevator (the fineness of the raw material entering the homogenization silo is 4%-7% on a 200µm sieve).
[0004] Current problems with raw material mills The dry powder of calcium carbide slag is mixed and stirred (80-100 t / h, 5%-10% residue on a 200 μm sieve). The mixed material is then fed into a homogenization silo via an elevator (the raw material entering the homogenization silo has a 200 μm fineness of 4%-7%). The fineness of the mixed material does not meet production requirements, and the fineness is difficult to control, resulting in a high powder concentration in the classifier, reducing classification efficiency, and increasing the operating resistance of the classifier, which increases wear inside the mill and affects the stability of the classifier's operation. Therefore, we propose a novel vertical mill classifier to solve the above problems. Utility Model Content

[0018] Specifically, the drive mechanism includes a motor mounting base 210, which is fixed to the top of the mounting base 100 by bolts. A drive motor 220 is fixed to the top of the motor mounting base 210. A drive shaft A230 is provided at the output end of the drive motor 220.

With the drive mechanism, the drive motor 220 drives the drive shaft A230 to rotate. The drive shaft A230, in conjunction with the reducer 240, drives the drive disk 250 to rotate at a low speed. The drive disk 250 drives the grinding mechanism to run.
[0019] Specifically, the grinding mechanism includes a mounting housing 310, to which the top of a reducer 240 is bolted. A grinding disc 320 is bolted to the top of a drive disc 250, and a grinding plate 330 is fixed to the top of the grinding disc 320. Multiple rocker arm assemblies 340 are bolted to the outer side of the mounting housing 310. A connecting sleeve 350 is rotatably connected to the inner wall of each rocker arm assembly 340. A mounting shaft 351 is rotatably connected to the inner wall of the connecting sleeve 350, and a grinding roller is fixed to the outer side of the mounting shaft 351. 360, an air inlet 370 is fixed to the side wall of the mounting housing 310; a grinding mechanism is provided, and the grinding disc 320 is driven to rotate by the driving mechanism. The rotation of the grinding disc 320 drives the grinding plate 330 to rotate. The grinding roller 360 rotates on the connecting sleeve 350 through the mounting shaft 351. Under the action of the rocker arm assembly 340, the grinding roller 360 is placed at a certain angle above the grinding disc 320.

With the transfer mechanism, the crushed large particles enter the bottom of the mounting housing 310. The rotation of the grinding disc 320 drives the material-pushing plate 410 to push the material, guiding it to the discharge trough A420. The material enters the conveyor 440 through the discharge trough A420 and is transported upwards by the conveyor 440. Finally, the material is transported back to the mounting housing 310 through the feeding trough 450, achieving repeated grinding of the material until it is ground into standard particles.
[0021] Working Principle: During operation, the air classifier is controlled by the main control unit 110. The drive motor 220 drives the drive shaft A230 to rotate. The drive shaft A230, in conjunction with the reducer 240, drives the drive disc 250 to rotate at low speed. The drive disc 250 drives the grinding disc 320 to rotate, which in turn drives the grinding plates 330 to rotate. The grinding roller 360 rotates on the connecting sleeve 350 via the mounting shaft 351. Under the action of the rocker arm assembly 340, the grinding roller 360 is positioned at a certain angle above the grinding disc 320. The grinding plates 330, in conjunction with multiple grinding rollers 360, grind and pulverize the material. Air is blown into the mounting housing 310 through the air inlet 370. The ground material is blown upward by the air. Larger particles of the pulverized material enter the bottom of the mounting housing 310. The rotation of the grinding disc 320 drives the material-pushing plate 410 to guide the material to the discharge chute A420. The material enters the conveyor 440 through the discharge chute A420, and is transported upwards by the conveyor 440. Finally, the material is transported back to the mounting housing 310 through the feeding chute 450, achieving repeated grinding of the material until it is ground into standard particles. The servo motor 610 drives the drive shaft B620 to rotate, which in turn drives a pair of guide blades 630 to rotate. The guide blades 630 guide and agitate the material powder. The drive shaft B620 also drives the drive frame 640 to rotate, which in turn drives the guide air ring 650 to rotate, guiding and agitating the material powder. The upper and lower guide blades 630 and the guide air ring 650 work together to pre-separate large particles of material powder, reducing the concentration of material powder continuing to rise and improving the efficiency of the powder selection operation.
