[0024] See also Figure 1 and Figure 3In the embodiment of the utility model, the driving mechanism 8 includes two transmission wheels 81, which are rotatably arranged on one side of the limit seat 7 and one side of the screen box 1 respectively. A gear plate 82 is arranged on one side of the transmission wheel 81 on the screen box 1, and a motor 83 is also installed on one side of the screen box 1. The output shaft of the motor 83 is connected with a main gear 84, and the main gear 84 is meshed with the gear plate 82. An eccentric rod 86 is hinged at the edge of the side of the gear plate 82 away from the transmission wheel 81, and one end of the eccentric rod 86 away from the gear plate 82 is hinged with a fixed plate 87, and one end of the fixed plate 87 away from the eccentric rod 86 is connected to a fixed shaft 88, and one end of the fixed shaft 88 away from the fixed plate 87 rotates through one side of the shell 41 and is connected to one end of the grinding roller 42.

[0025] In the above scheme, when the first screen plate 3 is screening, impurities and block materials will slide into the shell 41 and fall between the grinding roller 42 and the toothed plate 44.

When impurities and block raw materials on the first screen plate 3 slide into the shell body 41, the raw materials and impurities will fall between the toothed plate 44 and the grinding roller 42 through the guide plate 102, which is convenient for grinding the raw materials.

[0028] Embodiment 2 is different from Embodiment 1 in that:

[0029] See also Figure 1 and Figure 3In the embodiment of the utility model, one end of the two transmission wheels 81 is connected to a vibrating member 85, and the vibrating member 85 includes a rotating shaft 851 connected to one end of the transmission wheel 81, and a cam 852 is arranged on the outside of the rotating shaft 851. When the two rotating shafts 851 rotate, the two cams 852 continuously hit and vibrate the bottom of the first screen plate 3 and the second screen plate 6 respectively, causing them to vibrate, and the two transmission wheels 81 are connected through a transmission belt 89.

[0030] In the above scheme: catalyst raw materials are added to the feed port 2, and the first screen plate 3 screens the raw materials. During screening, the motor 83 drives the main gear 84 to rotate, and the main gear 84 drives the gear plate 82 meshing therewith to rotate, and the gear plate 82 will drive the cam 852 on the rotating shaft 851 to rotate, and the cam 852 will knock the bottom of the first screen plate 3, causing the first screen plate 3 to vibrate, thereby improving the screening effect of the first screen plate 3 on the raw materials. The block raw materials are ground and fall onto the second screen plate 6. When the gear plate 82 rotates, the transmission wheel 81 on the gear plate 82 causes the transmission belt 89 to drive another transmission wheel 81 to rotate, and the transmission wheel 81 drives the cam 852 on the rotating shaft 851 to rotate, and the cam 852 vibrates the bottom of the second screen plate 6, thereby improving the screening effect of the second screen plate 6.

A movable plate 52 is rotatably provided on the upper part of the partition 51, and the partition 51 is fixed by rotating the movable plate 52. After the screening is completed, the movable plate 52 is rotated to leave the upper part of the partition 51, and then the partition 51 is removed, and the impurities on the second screen plate 6 will be discharged.

[0032] Working principle: Add catalyst raw materials into the feed port 2, and the first screen plate 3 screens the raw materials. During screening, the motor 83 drives the main gear 84 to rotate, and the main gear 84 drives the gear plate 82 meshed with it to rotate, and the gear plate 82 will drive the cam 852 on the rotating shaft 851 to rotate, and the cam 852 will knock the bottom of the first screen plate 3, so that the first screen plate 3 vibrates, thereby improving the screening effect of the first screen plate 3 on the raw materials;

[0033] When the first screen plate 3 is screening, impurities and block materials will slide into the housing 41 and fall between the grinding roller 42 and the toothed plate 44. When the gear plate 82 rotates, the eccentric rod 86 drives the fixed plate 87 to rotate, the fixed plate 87 drives the fixed shaft 88 to rotate, and the fixed shaft 88 drives the grinding roller 42 to rotate. At the same time, the distance between the toothed plate 44 and the grinding roller 42 is adjusted by rotating the bolt rod 43. Under the rotation of the grinding roller 42, the agglomerated materials can be ground;

[0034] After the block material is ground, it falls onto the second screen plate 6. When the gear plate 82 rotates, the transmission wheel 81 on the gear plate 82 causes the transmission belt 89 to drive another transmission wheel 81 to rotate. The transmission wheel 81 drives the cam 852 on the rotating shaft 851 to rotate. The cam 852 vibrates the bottom of the second screen plate 6 to improve the screening effect of the second screen plate 6.

[0035] After the screening is completed, the movable plate 52 is rotated to leave the upper part of the partition plate 51, and then the partition plate 51 is removed, and the impurities on the second screen plate 6 will be discharged.
