Description

Technical Field

[0001] This utility model belongs to the field of chemical industry, and specifically relates to a vibrating screen for chemical materials. Background Technology

[0002] The vibrating screen for chemical materials is a mechanical device specifically used for screening, grading, and removing impurities from materials in the chemical industry. It separates materials of different particle sizes through vibration and is suitable for processing chemical raw materials, granules, powders, and other materials.

[0003] In existing vibrating screens for chemical materials, the screen mesh is often fixed to the inner wall of the screening layer with screws. To ensure the stability of the screen mesh during operation, a large number of screws may be used to fix the screen mesh. However, when the screen mesh needs to be replaced, a large number of screws may make the disassembly process cumbersome. Moreover, during vibrating screening, the screws may loosen slightly due to vibration, which may have a certain impact on the screening of materials. When screening materials with strong adhesion, the screen mesh may become clogged. The commonly used bouncing balls have limited effect on clearing clogged screen meshes, and it may be necessary to stop the machine for cleaning. Utility Model Content

[0004] To overcome the problems of cumbersome disassembly and potential screen blockage during the use of chemical material vibrating screens, a chemical material vibrating screen is proposed.

[0005] The technical solution of this utility model is as follows: A vibrating screen for chemical materials includes a screening drum and a vibrating drum, and also includes a vibrating motor, a cleaning drum, and a strip brush. The inner wall of the screening drum has four first grooves evenly distributed around its circumference. The right end inner wall of each first groove has vertically distributed square grooves and second grooves. The lower inner wall of the second groove is flush with the lower inner wall of the first groove. The inner wall of the screening drum is provided with vertically distributed limiting rings and a screen. The outer wall of the limiting rings is fixedly connected to four limiting blocks evenly distributed around its circumference. The outer wall of the screen is fixedly connected to four supporting blocks evenly distributed around its circumference. The limiting blocks are connected to the first grooves. The support block is adapted to the second trough. The lower end of the limiting ring is attached to the upper end of the screen. A spring pin is fitted on the inner wall of the square trough. The upper end of the spring pin is arc-shaped, and the lower end of the spring pin is attached to the upper end of the limiting ring. A cleaning barrel is fixed to the lower end of the screening barrel. A support frame is fixed to the inner wall of the lower end of the cleaning barrel. A motor is installed on the upper end of the support frame. A strip brush is provided on the inner wall of the cleaning barrel. A rotating shaft is fixed to the center of the lower end of the strip brush. The rotating shaft of the strip brush is connected to the output end of the motor. A sliding groove is opened at the upper end of the cleaning barrel, and sliders are fixed to the front and rear ends of the strip brush. The sliding groove and the slider are adapted to each other. The upper end of the strip brush is attached to the lower end of the screen.

[0006] Furthermore, a circular groove is provided at the lower end of the second groove, and a spring protrusion is fixedly connected inside the circular groove.

[0007] Furthermore, a limiting hole is provided at the lower end of the support block, and the spring protrusion is adapted to the limiting hole.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-7 This utility model provides an embodiment: a vibrating screen for chemical materials, including a screening barrel 1 and a vibrating barrel 2, and further including a vibrating motor 4, a cleaning barrel 5, and a strip brush 20. The inner wall of the screening barrel 1 has four first grooves 6 equidistantly distributed around the screening barrel 1. The right end inner wall of the first groove 6 has vertically distributed square grooves 8 and second grooves 7. The lower inner wall of the second groove 7 is flush with the lower inner wall of the first groove 6. The inner wall of the screening barrel 1 is provided with vertically distributed limiting rings 12 and screens 3. The outer wall of the limiting rings 12 is fixedly connected to four limiting blocks 13 equidistantly distributed around the limiting rings 12. The outer wall of the screens 3 is fixedly connected to four support blocks 14 equidistantly distributed around the screens 3. The limiting blocks 13 are adapted to the first grooves 6, and the support blocks 14... Adapted to the second trough 7, the lower end of the limiting ring 12 is attached to the upper end of the screen 3. A spring pin 11 is fitted on the inner wall of the square trough 8. The upper end of the spring pin 11 is arc-shaped, and the lower end of the spring pin 11 is attached to the upper end of the limiting ring 12. A cleaning bucket 5 is fixed to the lower end of the screening bucket 1. A support frame 16 is fixed to the inner wall of the lower end of the cleaning bucket 5. A motor 18 is installed on the upper end of the support frame 16. A strip brush 20 is provided on the inner wall of the cleaning bucket 5. A rotating shaft is fixed to the center of the lower end of the strip brush 20. The rotating shaft of the strip brush 20 is connected to the output end of the motor 18. A sliding groove 17 is opened at the upper end of the cleaning bucket 5, which surrounds the cleaning bucket 5. A slider 21 is fixed to the front and rear ends of the strip brush 20. The sliding groove 17 and the slider 21 are adapted to each other. The upper end of the strip brush 20 is attached to the lower end of the screen 3.

[0025] By sliding the support block 14 inside the second groove 7, the screen 3 can be supported. The limiting block 13 is slidably set at the bottom of the first groove 6 to limit and fix the support block 14. The spring pin 11 extends to press the limiting ring 12 to limit and fix the screen 3. Pushing the spring pin 11 back allows the limiting ring 12 and the screen 3 to be removed. This ensures the stability of the screen 3 while facilitating its disassembly and replacement. The output end of the motor 18 can drive the strip brush 20 to rotate. The rotation of the strip brush 20 can clean the lower end of the screen 3, reducing the probability of screen 3 clogging.

[0026] Please see Figures 4-5 In this embodiment, a circular groove 9 is provided at the lower end of the second groove 7, and a spring protrusion 10 is fixedly connected in the circular groove 9. In use, the circular groove 9 can limit the spring protrusion 10, allowing the spring protrusion 10 to move up and down in the circular groove 9. A limiting hole 15 is provided at the lower end of the support block 14, and the spring protrusion 10 is adapted to the limiting hole 15. In use, the support block 14 can be limited and fixed by the spring protrusion 10 and the limiting hole 15, which can improve the stability of the screen 3.

[0027] Please see Figures 6-7 In this embodiment, a motor cover 19 is installed on the outer wall of the motor 18, and a sorting barrel 23 is installed at the lower end of the cleaning barrel 5 by bolts. During use, the motor cover 19 can protect the motor. The sorting barrel 23 can sort the screened material. A vibrating barrel 2 is installed at the lower end of the sorting barrel 23 by bolts. A vibration motor 4 is installed on the inner wall of the vibrating barrel 2. During use, the vibration motor 4 can make the vibrating barrel 2 vibrate, which can drive the screening barrel 1 to vibrate.

[0028] Please see Figure 7 In this embodiment, the lower end of the vibrating drum 2 is fixedly connected to the fixed end of the shock absorber 24, and the output end of the shock absorber 24 is fixedly connected to the base 25. During use, the shock absorber 24 can dampen the vibration of the vibrating motor 4 and reduce the transmission of vibration to the ground. The upper end of the screening drum 1 is bolted to the top cover 22, and the upper opening of the top cover 22 is fixedly connected to the funnel. During use, the top cover 22 can protect the material screening and prevent dust from overflowing.

[0029] When working, first, place the containers below the discharge port of screening barrel 1 and the discharge port of sorting barrel 23 respectively, and start the vibration motor 4. Then, pour the material to be screened into screening barrel 1 from the top of the cover 22. Then, wait for the material to be screened by the screen 3 so that the material at the top of the screen 3 and the screened material are guided into the container. Finally, start the motor 18 and wait for the output end of the motor 18 to drive the strip brush 20 to clean the bottom of the screen 3.

[0030] When the screen 3 needs to be replaced, first press the spring pin 11 to press the spring pin 11 into the square groove 8, and pull the limiting ring 12 upward. Then, rotate the screen 3 counterclockwise so that the support block 14 is aligned with the first groove 6, and the screen 3 can be removed. Then, align the support block 14 on the new screen 3 with the first groove 6 and press it down. When the screen 3 is pressed to the bottom of the first groove 6, rotate the screen 3 clockwise so that the spring protrusion 10 engages with the limiting hole 15. Finally, align the limiting block 13 of the limiting ring 12 with the first groove 6 and press it down so that the spring pin 11 presses the limiting ring 12.

[0031] Through the above steps, the support block 14 is slidably set in the second trough 7 to provide support for the screen 3. The limiting block 13 is slidably set at the bottom of the first trough 6 to limit and fix the support block 14. The spring pin 11 extends to press the limiting ring 12 to limit and fix the screen 3. The output end of the motor 18 can drive the strip brush 20 to rotate. The rotation of the strip brush 20 can clean the lower end of the screen 3. This solves the problem that the disassembly of the screen is cumbersome and may cause screen blockage when using the vibrating screen for chemical materials.
