Description

Technical Field

[0001] This utility model relates to the field of ultrafine pulverizer technology, specifically to a material classification mechanism for an ultrafine pulverizer. Background Technology

[0002] In modern industrial production, ultrafine grinding technology is widely used in many fields such as food, medicine, chemical industry, and materials. It aims to grind materials into fine particles at the micron or even nanometer level to meet the specific requirements of different products for material particle size. When the ultrafine grinder is working, after the material is ground in the grinding chamber, a material classification mechanism of the ultrafine grinder is needed to separate the finished product that meets the particle size requirements from the material that does not meet the requirements, so as to ensure the precise control of product particle size.

[0003] However, due to the poor grading and anti-clogging capabilities of the material grading mechanism in the existing ultrafine pulverizer, it is not convenient to quickly and effectively grade the pulverized material in actual use. Some grading mechanisms use a simple screen structure, relying on the material's own gravity and motion inertia for grading. Its grading efficiency is low, it cannot effectively separate materials with similar particle sizes, and it is easy to cause clogging of the grading screen, affecting the grading processing efficiency.

[0025] The anti-blocking grading mechanism 4 includes a first mounting plate 401. The first mounting plate 401 is fixedly mounted on one side of the top of the grading box 1. A first sliding groove 402 is formed at the bottom end of the first mounting plate 401. A drive motor 403 is fixedly mounted on one side of the first mounting plate 401. The output shaft of the drive motor 403 is fixedly connected to a transmission threaded rod 404 via a coupling. The transmission threaded rod 404 extends into the interior of the first sliding groove 402. A [missing information - likely a device or component] is fixedly mounted on the inner wall of the first sliding groove 402 on the side away from the drive motor 403. Bearing housing 405, transmission threaded rod 404 is fixedly connected to the inside of bearing housing 405 on the side away from drive motor 403, and sliding screw block 406 is threadedly connected to the outer end of transmission threaded rod 404. Second mounting plate 407 is fixedly installed on the top of the classifier 1 on the side away from first mounting plate 401. Second sliding groove 408 is opened at the bottom of second mounting plate 407. First sliding groove 402 and second sliding groove 408 correspond to limiting through groove 3. Support rod 40 is fixedly installed inside second sliding groove 408. 9. A movable slider 410 is sleeved on the outer end of the support rod 409. An adjusting sleeve 411 is fixedly installed on the bottom end of the sliding screw block 406 and the movable slider 410. The adjusting sleeve 411 extends through the limiting groove 3 into the interior of the grading box 1. An adjusting movable rod 412 is sleeved inside the adjusting sleeve 411. An anti-clogging brush 413 is fixedly installed on the bottom end of the adjusting movable rod 412. The anti-clogging brush 413 extends movably to the bottom end of the grading filter screen frame 2. Several limiting screw holes 4 are evenly opened on one side of the adjusting movable rod 412. 14. A limit bolt 415 is threadedly connected to one side of the adjusting sleeve 411. The limit bolt 415 passes through the adjusting sleeve 411 and is threadedly connected to the limit screw hole 414. The drive motor 403 is started. The output shaft of the drive motor 403 drives the transmission threaded rod 404 to rotate in the bearing seat 405. The sliding screw block 406 moves horizontally back and forth along the first sliding groove 402. At the same time, the moving slider 410 slides synchronously on the support rod 409 to ensure that the adjusting sleeve 411 moves smoothly along the limit through groove 3, thereby driving the anti-clogging brush 413 to move.

[0026] A feed hopper 5 is fixedly installed at the top of the grading box 1. Connecting sliders 6 are fixedly installed on both sides of the grading filter frame 2. Connecting grooves 7 are opened on the inner walls of both sides of the grading box 1. The connecting sliders 6 are movably connected inside the connecting grooves 7. A discharge pipe 8 is fixedly installed on one side of the grading box 1. A solenoid valve 9 is installed in the middle of the discharge pipe 8. A sealing door 10 is hinged to one side of the grading box 1. An observation window 11 is fixedly installed in the middle of the sealing door 10. The grading filter frame 2 is smoothly installed into the grading box 1 through the sliding cooperation between the connecting sliders 6 and the connecting grooves 7.

[0027] Working Principle: When using the material grading mechanism of this ultrafine pulverizer, firstly, select the corresponding specification of the grading filter frame 2 according to the particle size requirements of the material to be graded. Through the sliding cooperation of the connecting slider 6 and the connecting groove 7, smoothly install the grading filter frame 2 into the grading box 1, ensuring the filter screen position is stable. Then, adjust the height of the anti-clogging brush 413, loosen the limit bolt 415, and pull the adjusting rod 412 to extend and retract within the adjusting sleeve 411, so that the anti-clogging brush 413 just fits against the filter screen surface of the grading filter frame 2. Then, screw the limit bolt 415 into the corresponding limit screw hole 414 to complete the fixing of the anti-clogging brush 413. Connect the external power supply and electrically connect the electrical components to the external control system. Pour the pulverized material from the ultrafine pulverizer into the feed hopper 5, and then cover it with the sealing cap. The material falls into the grading filter frame 2 under gravity. At this time, start the drive motor 403. The output shaft of the drive motor 403 drives the transmission threaded rod 404. Rotating within the bearing housing 405, the sliding screw block 406 is threadedly connected to the transmission threaded rod 404. The sliding screw block 406 reciprocates horizontally along the first sliding groove 402, while the moving slider 410 slides synchronously on the support rod 409, ensuring that the adjusting sleeve 411 moves smoothly along the limiting through groove 3. This drives the anti-clogging brush 413 to clean back and forth within the grading filter frame 2. Under the cleaning action of the anti-clogging brush 413, the material is quickly dispersed. Fine particles that meet the particle size requirements fall through the filter screen into the bottom of the grading box 1, while coarse particles that do not pass through the filter screen are intercepted within the grading filter frame 2. The operator can observe the grading situation in real time through the observation window 11. After grading is completed, the solenoid valve 9 is opened, and the finished material at the bottom of the grading box 1 is discharged and collected through the discharge pipe 8. After the grading operation is completed, the drive motor 403 and the solenoid valve 9 are turned off, the sealing door 10 is opened, and the grading filter frame 2 is pulled out along the connecting slide groove 7 to clean the remaining coarse particles inside.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
