[0019] Example: Figure 1-6As shown, this utility model provides a fine chemical screening device, including a screening box 1. A drive shaft 8 is rotatably installed inside the screening box 1. A second motor 6 is fixedly installed at the top of the screening box 1, and the output end of the second motor 6 is fixedly connected to the top of the drive shaft 8. Multiple mounting plates 801 arranged in a ring are fixedly installed on the drive shaft 8. Each mounting plate 801 is detachably mounted with a hopper 9 by bolts. Each hopper 9 has a filter screen 11 fixedly installed at its top, and the mesh count of the filter screens 11 on each hopper 9 is different. A material cylinder 7 is fixedly installed on one side inside the screening box 1, and the bottom end of the material cylinder 7 can be connected to the upper surface of the filter screen 11 on the corresponding hopper 9. With the top diameter of the hopper 9 being larger than the bottom diameter of the cylinder 7, the hopper 9, equipped with filter screens 11 of different mesh sizes, can be detachably mounted on the mounting plate 801 on the drive shaft 8 using bolts. According to different screening specifications, the second motor 6 drives the drive shaft 8 to rotate, and the drive shaft 8 drives the corresponding hopper 9 to rotate directly below the cylinder 7. The bottom of the cylinder 7 contacts the upper surface of the filter screen 11, allowing the chemical materials to be screened to be placed into the cylinder 7. The chemical materials are then subjected to multi-stage fine screening through multiple filter screens 11 of different sizes. The detachable hopper 9 facilitates the disassembly, cleaning, or replacement of the hopper 9 and the filter screen 11.
[0020] The top of the screening box 1 is provided with a feed inlet 102, and the feed inlet 102 is connected to the inside of the material cylinder 7. A feed pipe 4 is fixedly installed at the feed inlet 102 at the top of the screening box 1, and the chemical materials are put into the material cylinder 7 through the feed pipe 4 and the feed inlet 102.
[0021] A stirring paddle 12 is rotatably installed inside the screening box 1, and the stirring paddle 12 is located inside the material cylinder 7. A first motor 5 is fixedly installed at the top of the screening box 1, and the output end of the first motor 5 is fixedly connected to the top of the stirring paddle 12. The first motor 5 can drive the stirring paddle 12 to rotate inside the material cylinder 7, which can accelerate the screening of materials inside the material cylinder 7.
[0022] The bottom of the screening box 1 is provided with a conical groove 10. The bottom of the screening box 1 is fixedly installed with a discharge pipe 3, and the discharge pipe 3 is connected to the inside of the conical groove 10, so that the screened material falls into the conical groove 10 and is discharged through the discharge pipe 3.
[0023] The top of the screening box 1 is provided with an inspection port 101. A cover plate 2 is hinged inside the inspection port 101.

The cover plate 2 can be fixed by using the fasteners 13.
[0024] Working Principle: In use, this invention first utilizes a second motor 6 to drive a drive shaft 8 to rotate according to different screening specifications. The drive shaft 8 rotates the corresponding hopper 9 to directly below the material cylinder 7, bringing the bottom of the material cylinder 7 into contact with the upper surface of the filter screen 11. Then, chemical materials are fed into the material cylinder 7 through the feed pipe 4 and feed inlet 102. A first motor 5 drives a stirring paddle 12 to rotate inside the material cylinder 7, accelerating the screening of the material. The screened material falls into the conical trough 10 and is discharged through the discharge pipe 3. Then, the second motor 6... Motor 6 drives drive shaft 8 to rotate, drive shaft 8 drives hopper 9 to rotate, causing hopper 9 and filter screen 11 to separate from cylinder 7. At the same time, cylinder 7 can scrape off the material separated on filter screen 11. When hopper 9 and filter screen 11 are completely separated from the bottom of cylinder 7, the material separated in cylinder 7 will fall into conical groove 10 and be discharged through discharge pipe 3. Different collection devices are used to collect the screened and separated materials. This process is repeated to perform multi-stage fine screening of chemical materials through multiple filter screens 11 of different specifications.
