Polyacrylamide of different particle sizes is screened according to different application requirements.

[0003] However, existing vibrating screens for acrylamide typically have the screen and the device fixed together, making it impossible to adjust the screen angle according to different screen apertures, thereby affecting the feeding efficiency. Therefore, it is necessary to propose a multi-stage screening vibrating screen for polyacrylamide to solve the aforementioned problems. Utility Model Content

[0014] This polyacrylamide uses a multi-stage vibrating screen. By unscrewing the bolts fixing the first and second slide rods, the third and second screen discs are removed from the limiting positions of the first and second limiting rods. A screen of the appropriate particle size is then installed. The threaded rod is then rotated, causing the threaded rod and slide block to rotate, which in turn moves the second connecting rod up and down.

This allows for screen replacement and adjustment of the working angles of the second and third screen discs, improving material feeding efficiency by adjusting the screen angle according to different screen apertures.

[0026] During operation, by unscrewing the bolts fixing the first slide rod 14 and the second slide rod 17, the third screen plate 4 and the second screen plate 3 are removed from the limiting positions of the first limiting rod 13 and the second limiting rod 16. A screen of the appropriate particle size is then installed. Then, the threaded rod 6 is rotated, causing the threaded rod 6 and the slider 20 to rotate threadedly, which drives the second connecting rod 19 to move up and down. This causes the left ends of the second screen plate 3 and the third screen plate 4 to move up and down. The limiting action of the fixing plate 8 on the limiting post 7 limits the height of the right end of the second screen plate 3 and the third screen plate 4 by the first connecting rod 15, thereby achieving the function of replacing the screen and changing the working angle of the second screen plate 3 and the third screen plate 4.

[0027] The bottom end of the second connecting rod 19 is rotatably connected to the second limiting rod 16, and the end of the second limiting rod 16 away from the second connecting rod 19 is rotatably connected to the bottom end of the first connecting rod 15.

[0028] During operation, the second limiting rod 16 serves to limit the second sliding rod 17.

[0029] The second limiting rod 16 is internally fixedly connected to the second sliding rod 17 by bolts, and one end of the second sliding rod 17 is fixedly connected to the second screen plate 3.

[0030] During operation, the second slide rod 17 serves to fix and connect the second screen plate 3.

[0031] The lower surface of the second limiting rod 16 is fixedly connected to the first screen plate 2.

[0032] During operation, the first screen plate 2 serves to receive larger particles of material.

[0033] The bottom end of the second connecting rod 19 is fixedly connected to a connecting block 18, and a threaded sleeve rod 11 is rotatably connected to one side of the connecting block 18.

[0034] During operation, the connecting block 18 serves to connect the threaded sleeve 11.

[0035] A base plate 1 is fixedly connected to the lower surface of the support column 9, and a motor 10 is fixedly connected to the upper surface of the base plate 1.

[0036] During operation, the motor 10 drives the rotating disk 12 to rotate.

[0037] The output end of the motor 10 is fixedly connected to a rotating disk 12. One side of the rotating disk 12, off-center, is rotatably connected to the end of the threaded sleeve 11 away from the connecting block 18.

[0038] During operation, the rotating disk 12 drives the threaded sleeve 11 to move.

[0039] The feeding box 5 is fixedly connected to the upper surface of the fixed plate 8.

[0040] During operation, the feeding box 5 is used to feed materials into the device.

[0041] Working principle: By unscrewing the bolts fixing the first slide rod 14 and the second slide rod 17, the third screen plate 4 and the second screen plate 3 are removed from the limiting positions of the first limiting rod 13 and the second limiting rod 16. A screen of the appropriate particle size is then installed. Next, the threaded rod 6 is rotated, causing the threaded rod 6 and the slider 20 to rotate threadedly, driving the second connecting rod 19 to move up and down. This, in turn, moves the left ends of the second screen plate 3 and the third screen plate 4 up and down. The limiting action of the fixing plate 8 on the limiting post 7 limits the height of the right end of the second screen plate 3 and the third screen plate 4 by the first connecting rod 15, thus achieving the purpose of replacing the screen and... The function of changing the working angle of the second screen plate 3 and the third screen plate 4 is to rotate and adjust the threaded sleeve rod 11 so that when the connecting block 18 is in a vertical state, the connection between the threaded sleeve rod 11 and the rotating disk 12 is at the highest position of the rotating disk 12. Material is fed into the feeding box 5, and then the motor 10 is started to drive the rotating disk 12 to rotate. The rotating disk 12 drives the threaded sleeve rod 11 to move. The threaded sleeve rod 11 pulls the connecting block 18, causing the second connecting rod 19 to swing around the slider 20, thereby realizing the screening of the material. The material is screened by different mesh sizes of the screen, and the material is classified according to different particle sizes.
