Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to an anti-sticking pulverizer capable of multi-stage pulverization. Background Art

[0002] A pulverizer is a mechanical device that crushes large solid raw materials into required sizes. It is widely used in mining, building materials, chemicals, food, pharmaceuticals, metallurgy and other industries to process various materials such as ore, limestone, coal, glass, plastic, rubber, wood, etc. The main purpose of a pulverizer is to crush materials into required particles or powders through high-speed impact, shearing, compression and other methods.

[0003] Existing crushers do not have multi-stage crushing capabilities. For some materials that require particularly fine crushing, the required fineness may still not be achieved after one crushing, and it is difficult to obtain an ideal crushing effect. For example, in the crusher disclosed in Publication No. CN206464056U, the material in this patent is mainly crushed by a rotating shaft and a knife holder. However, a single crushing may not ensure that the material reaches a uniform and consistent particle size. Different material particles may differ in hardness, shape and size. One-time crushing may cause some particles to be too large or too small, and thus cannot meet the requirements for precise control of particle size in the production or processing process. Additional processing steps or the use of other equipment for further crushing are required, which not only increases production time and energy consumption, but may also affect the quality of the material.

[0004] Therefore, it is necessary to invent a multi-stage anti-sticking crusher to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-6 The anti-sticking pulverizer capable of multi-stage pulverization shown in the figure comprises a chassis 1, a support leg 2 is fixedly installed on the outer wall of the chassis 1, and the support leg 2 is provided with 4, and the four support legs 2 are perpendicular to the chassis 1, a crushing box 3 is fixedly installed above the chassis 1, and a feed hopper 4 is installed on the top of the crushing box 3, and a No. 1 motor 5 is arranged on one side above the chassis 1, and a small pulley 6 is fixedly connected to the output end of the No. 1 motor 5, and a large pulley 7 is arranged just above the small pulley 6, and a transmission belt 8 is tensioned on the small pulley 6 and the large pulley 7, and one end of the large pulley 7 is fixedly connected to a No. 1 gear 9, and the feed hopper 4 is arranged on the top side of the chassis 1. A crushing roller 10 is arranged below the hopper 4, anti-stuck tooth blocks 11 are fixedly installed on the inner walls of the front and rear sides of the crushing box 3, a filter box 12 is arranged below the crushing roller 10, a No. 2 motor 15 is fixedly installed on the side wall of the chassis 1, a No. 1 bevel gear 16 is fixedly connected to the output end of the No. 2 motor 15, a No. 2 bevel gear 17 is meshed and connected to the top of the No. 1 bevel gear 16, a grinding wheel 19 is fixedly connected to one side of the No. 2 bevel gear 17, and a No. 2 gear 18 is fixedly connected to the end of the grinding wheel 19, scrapers 20 are fixedly installed on the inner walls of the front and rear ends of the chassis 1, and a lower hopper 21 is fixedly installed at the bottom of the chassis 1.

[0027] A crushing roller 10 is arranged inside the crushing box 3, and there are two crushing rollers 10. One end of the two crushing rollers 10 is fixedly connected to a No. 1 gear 9, and the other ends of the two crushing rollers 10 are rotatably connected to the inner wall of the crushing box 3.
