Description
Technical Field
[0001] This utility model relates to the field of chemical material screening technology, specifically a chemical material screening device. Background Technology
[0002] Chemical materials refer to various materials used in the chemical industry. They can be naturally occurring or artificially synthesized. They are used as raw materials, catalysts, additives, or products in chemical production processes. The scope is very broad, including plastics, rubber, fibers, inorganic non-metallic materials, alloys, coatings, adhesives, etc. Chemical materials have wide applications in daily life, industrial production, and technological development.
[0003] Traditional screening technologies typically have low efficiency, making it difficult to achieve rapid and accurate multi-stage screening of mixed chemical materials with varying particle sizes in a single operation. They may also lack the flexibility to adjust screening precision, and the equipment design may hinder the rapid installation, disassembly, and maintenance of screening components, leading to cumbersome and time-consuming operations such as screen replacement or cleaning of residual materials. Furthermore, structural stability and versatility may be compromised. This invention achieves three-stage screening of chemical materials through a screening cylinder and screening components using a third, first, and second screening screen. A motor drives the screening cylinder and screening components to rotate, aided by centrifugal force... Force and gravity enable materials to pass quickly through screens of different apertures, greatly improving screening efficiency. Different particle sizes can be accurately separated in a single operation. The base support legs ensure stability, and the screening components rotate smoothly through the cooperation of connecting rods, bushings, and movable rods. The screening groove of the base and the screening screen clips of the screening plate facilitate the installation and disassembly of the screening plate. Pulling out the fixing rod and pulling the handle allows for easy replacement or cleaning of the screen, reducing maintenance difficulty and time costs. The screening accuracy can also be flexibly adjusted according to the particle size of the material, and different aperture screens can be replaced to improve the versatility of the equipment. Therefore, we have proposed a chemical material screening device. Utility Model Content

A bushing 15 is engaged inside the bushing groove 20. A connecting rod 22 is fixed at the center of the bottom of the screening component 16. A gear 3 24 is fixed on the connecting rod 22. Four movable rods 23 with symmetrical central axes are fixed at the bottom of the gear 3 24. The connecting rod 22 is inserted into the bushing 15. The movable rods 23 slide in accordance with the annular movable groove 21, so as to realize the stable and flexible rotation of the screening component 16, and provide a stable operating foundation for the subsequent efficient screening of chemical materials.
[0028] Furthermore, the front end of the base 3 is provided with three equally distributed screening grooves 26. Four screening mesh clips 31 with central axis symmetry are fixed on the screening plate 10. The receiving tray 12, the first screening mesh 13 and the second screening mesh 14 are respectively clipped onto the three screening plates 10 in cooperation with the screening mesh clips 31. The three screening plates 10 slide in the corresponding screening grooves 26. The first screening mesh 13 and the second screening mesh 14 have different apertures, which facilitates the classification and screening of chemical materials and facilitates the installation, replacement and maintenance of the screening plates 10.
[0029] Furthermore, symmetrically arranged gel bait 25s are fixed to the bottom of the screening tank 26 and the front surface of the base 3. Symmetrically arranged gel bait 30s are fixed to the front of the screening plate 10. A handle is fixed between the two gel baits 30s. A fixing rod 11 is inserted into the gel bait 30. The end of the fixing rod 11 is inserted into the gel bait 25 to ensure the stability of the screening process. At the same time, it is convenient to pull out the fixing rod 11 by pulling the handle to disassemble the screening plate 10 for cleaning or replacement.
[0030] Furthermore, the top surface of the screening component 16 is provided with a circular mating groove 27, and the bottom end of the screening cylinder 17 is fixed with a circular mating block 28.

[0031] Furthermore, gear 3 24 and gear 4 29 are fixed to the bottom end of the screening element 16 and the cylindrical surface of the screening cylinder 17, respectively. A mounting frame 5 is fixed to the top left of the base 3. Multiple support plates are fixed on the mounting frame 5. Motor 1 6 and motor 2 8 are respectively mounted on the support plates. The output shafts of motor 1 6 and motor 2 8 pass through the bottom and top ends of the support plates, respectively. Gear 1 7 and gear 2 9 are fixedly connected to the output shafts of motor 1 6 and motor 2 8. Gear 2 9 meshes with gear 4 29. The motor drives the gears to rotate, thereby driving the screening element 16 and the screening cylinder 17 to rotate, realizing the effective screening operation of chemical materials.
[0032] Working principle: The chemical material to be screened is poured into hopper 2, which is connected to conveying pipe 19. Since the right end of conveying pipe 19 is engaged in an inclined groove at the top of support bar 4, and the left end is inserted into the feed inlet at the top of screening cylinder 17, the material slides into screening cylinder 17 under gravity along conveying pipe 19. A third screening screen 18 is engaged inside screening cylinder 17. Motor 2 8 on mounting frame 5 starts, and its output shaft drives gear 2 9 to rotate. Gear 2 9 meshes with gear 4 29 fixed on the cylindrical surface of screening cylinder 17, thereby driving screening cylinder 17 to rotate around its own axis. During the rotation, the chemical material comes into contact with the third screening screen 18 under the action of centrifugal force and its own gravity. Particles smaller than the aperture of the third screening screen 18 pass through the screen and fall into the screening element 16 below. Particles larger than the aperture remain on the third screening screen 18, waiting for subsequent cleaning. At the same time, the motor 6 also starts to work. The output shaft of the motor 6 drives the gear 7 to rotate. The gear 7 meshes with the gear 24 fixed at the bottom of the screening element 16, causing the screening element 16 to rotate around the connecting rod 22 on the bushing 15. Three equally distributed screening plates 10 are inserted inside the screening element 16. Each screening plate 10 is respectively fitted with a receiving tray 12, a first screening screen 13, and a second screening screen 14. When the material falling from the screening cylinder 17 enters the screening element 16, under the rotation of the screening element 16, the material moves on the screening plate 10. Particles smaller than the aperture of the first screening screen 13 pass through the first screening screen 13 and fall into the receiving tray 12. Particles larger than the aperture of the first screening screen 13 but smaller than the aperture of the second screening screen 14 remain on the first screening screen 13, while particles larger than the aperture of the second screening screen 14 remain on the second screening screen 14. The first screening screen 13 and the second screening screen 14 have different apertures, which realizes further classification and screening of chemical materials. The front end of the base 3 has three equally distributed screening grooves 26. The screening plate 10 is locked in the screening groove 26 by the screening screen clip 31 and can slide in it. When it is necessary to replace the screening plate 10 or clean the residual material on the screen, the fixing rod 11 can be pulled out. It was originally inserted between the second glue 30 and the first glue 25 for fixing. Then, by pulling the handle, the screening plate 10 is slid out along the screening groove 26 for convenient subsequent operation.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
