Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a dust-proof pulverizer. Background Art

[0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. It consists of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of crushing in the form of high-speed impact. The pulverizer uses wind energy to produce powder in one go, eliminating the traditional screening process. According to the size of the crushed or crushed materials, the pulverizer can be divided into coarse crusher, pulverizer, and ultra-fine pulverizer. There are four external forces applied to the solid during the crushing process: shearing, impact, rolling, and grinding. The actual crushing process is often several external forces acting at the same time, but high-end pulverizers are tailored to the crushing environment. Pulverizers are mainly used in various industries such as mining and building materials. Generally, the mined metal mineral salt needs to be crushed and processed by a pulverizer to facilitate the subsequent transportation and use of the mineral salt.

[0003] The existing Chinese patent with announcement number CN215506954U discloses an ore crusher, including a crushing box and a plurality of first triangular plates and a second triangular plate installed on both sides of the crushing box, two rotating shafts rotating in opposite directions are installed between the first triangular plate and the second triangular plate, the triangular plate is a right triangle, the right-angled sides of the triangular plate are fixedly installed on the bottom and side of the crushing box respectively, the hypotenuse of the first triangular plate and the second triangular plate are arranged oppositely, and a plurality of convex nails are fixedly installed on the hypotenuse of the triangular plate, and the top of the convex nail is provided with a stress protrusion with a diameter smaller than the bottom of the convex nail, and the stress protrusion is used to generate a fixed-point force on the ore; the utility model adds structures such as convex nails around the crusher, so that the ore has a relatively concentrated point contact when it contacts the crusher, thereby concentrating the stress at a certain point of the ore, and the internal stress of the ore changes under the action of multiple directional forces, and then it is crushed by the action of the crushing blade, thereby reducing the difficulty of crushing, improving the efficiency of crushing, and effectively protecting the crusher.

[0004] However, the above-mentioned device has the following disadvantages: a large amount of dust will be generated when the mined ore is crushed. Part of the dust comes from the floating dust on the surface of the ore, and part of it comes from the dust generated by some small fragments when the ore is crushed. The above-mentioned crushing device is not provided with a dust prevention mechanism, which will cause a large amount of dust to be raised when the ore is crushed. A large amount of dust will pollute the environment, and the splashing crushed stone chips will also affect the crushing work. In the prior art, a water mist device is generally used to reduce dust, but the water mist device can only reduce dust in a specific direction. However, during the crushing process of the crusher, dust is dispersed from all directions inside the crusher. The traditional water mist device has low dust prevention performance.

[0005] Therefore, it is necessary to provide a dust-proof pulverizer to solve the above-mentioned technical problems. Utility Model Content
