Description

Technical Field

[0001] This utility model relates to the field of medicinal material pulverization technology, and in particular to a pulverizer with a dust collection function. Background Technology

[0002] Crusher is widely used in the pharmaceutical and health product fields. It is mainly used to crush materials to the particle size that meets the production requirements. Through high-speed rotating blades or grinding parts, it shears and impacts medicinal materials and health product raw materials, which can effectively process medicinal materials. Universal crusher is suitable for crushing general materials, while ultra-micro crusher can achieve micron-level crushing, improving drug dissolution and bioavailability.

[0003] The working principle of a pulverizer is based on the destructive effect of mechanical force on medicinal materials. It achieves the crushing target through different structural designs. The core is to use the shearing, squeezing, impact or grinding force generated by moving parts to make the internal stress of the material exceed its own strength limit and break it. The shearing force is formed by two sets of staggered rotating blades to pulverize the medicinal materials into appropriate particle sizes.

[0004] Dust generated during the crushing process accumulates inside or around the equipment, adhering to components such as circuits and bearings, affecting heat dissipation and operation, increasing the risk of failure, and shortening the service life. Scattered dust requires extra time to clean, especially fine particles that easily accumulate in corners or equipment crevices, making cleaning difficult. This not only reduces work efficiency but also poses a risk of static electricity or even fire due to dust accumulation. Therefore, a crusher with a dust collection function is proposed to solve the above problems. Utility Model Content

[0036] Working principle: The raw material is placed into the bucket 4 and started. The bucket 4 drives the gear 6 to rotate, which in turn drives the gear 7 to rotate. The gear 6 drives the cutter 8 to rotate, and the gear 7 drives the cutter 9 to rotate, thus crushing the raw material. During the crushing process, dust is generated. The dust collector 15 is started, and the dust is absorbed through the dust collection hopper 10. At the same time, the dust collection hopper 10 is equipped with an inclined filter plate 17 to block the crushed material. The dust enters the inside of the cylinder 12 through the dust collection pipe 11 and hits the inner wall of the cylinder 12. The bottom of the cylinder 12 has a conical hopper 18. According to gravity, it rotates and moves downward on the inner wall of the cylinder 12 and falls into the dust collection box 19. The dust collection box 19 has a rotating dust collection hopper 20 inside, which can be pulled out to prevent the dust from being sucked out again. After the dust removal is completed, the cover plate 21 can be pulled to discharge the dust in the dust collection box 19. The dust-free gas enters the dust collector 15 through the air inlet pipe 14 and is finally discharged through the air outlet pipe 16.

[0037] During the dust collection process, a lot of pulverized material will adhere to the outside of the filter plate 17, affecting the dust removal effect. The motor 23 is started, which drives the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the follower rod 25 to swing. The swing of the follower rod 25 drives the support plate 26 to move up and down. The support plate 26 drives the limiting post 27 to move up and down. A spring 28 is connected between the support plate 26 and the follower plate 29. The spring 28 vibrates, which drives the follower plate 29 to move up and down. The movement of the follower plate 29 drives the vibrating hammer 31 to move up and down through the fixed post 30, vibrating the dust collection hopper 10 and shaking off the attached material on the surface of the filter plate 17, so as to keep the dust removal process smooth.
