Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to a dust removal device for protecting a hammer mill. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and pneumatic conveying devices. It achieves the purpose of crushing by high-speed impact. It is mainly used in mining, building materials and other industries. When a hammer crusher is crushing charcoal blocks, charcoal fragments often splash out from the feed inlet, so a dust removal device is needed to protect the hammer crusher.

[0003] Existing dust protection devices for hammer mills typically have a filter screen installed at the feed inlet to prevent debris from splashing and injuring workers or affecting the equipment. However, some debris remains on the filter screen, which not only wastes resources but also makes replacing the filter screen cumbersome. Therefore, we propose a dust protection device for hammer mills. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology. The existing dust removal device for hammer crushers usually has a filter screen installed at the feed inlet to prevent debris from splashing and causing injury to workers or affecting the equipment.

[0033] Example 1

[0034] like Figure 1-4 As shown, this utility model provides a technical solution: a dust removal device for a hammer mill, including a mill body 1, and a recycling device 2 installed on the right side of the mill body 1; the recycling device 2 includes a U-shaped outer shell 201, with a recycling trough 202 inside the U-shaped outer shell 201, into which debris enters; a drive motor 203 is installed on the inner wall of the U-shaped outer shell 201 at the end away from the mill body 1, and a fan 204 is installed at the output end of the drive motor 203, which can drive the fan 204 to rotate and extract the air from inside the recycling trough 202; a recycling box 205 is installed on the inner wall of the U-shaped outer shell 201 near the fan 204, and a dustproof net 206 is fixed to the bottom surface of the inside of the recycling box 205. The dustproof net 206 can intercept debris, allowing it to fall into the recycling box 205. A rotating handle 207 is installed on the outer wall of the recycling box 205. The rotating handle 207 extends into the interior of the recycling box 205 and a rotating gear 208 is installed therein. A mounting groove 209 is provided inside the recycling box 205 corresponding to the rotating gear 208. A rack 210 is symmetrically installed on the inner wall of the mounting groove 209 corresponding to the rotating gear 208. The rotating handle 207 can drive the rotating gear 208 to rotate, thereby driving the rack 210 to move. A slot 211 is provided on the inner wall of the U-shaped outer shell 201 corresponding to the rack 210. The rack 210 can be locked inside the slot 211 to help fix the recycling box 205.

[0035] Example 2

[0036] like Figure 1-4As shown, a feed pipe 101 is installed at the top of the crusher body 1. The feed pipe 101 is connected to the interior of the crusher body 1. Through the connection between the feed pipe 101 and the interior of the crusher body 1, the feed pipe 101 can transport materials into the interior of the crusher body 1.

[0037] The bottom of the crusher body 1 is fixed with a support base 102 near the corner. The support base 102 is made of rubber. The support base 102 made of rubber can support the crusher body 1 and can also play a certain role in shock absorption.

[0038] The U-shaped outer shell 201 is made of stainless steel. The recycling tank 202 is connected to the interior of the crusher body 1. The U-shaped outer shell 201, made of stainless steel, has a relatively stable structure and a long service life.

[0039] The fan 204 is adapted to the recycling bin 202, and the recycling box 205 is adapted to the recycling bin 202. The adaptation of the fan 204 to the recycling bin 202 ensures that the fan 204 is not affected when rotating, while the adaptation of the recycling box 205 to the recycling bin 202 allows the recycling box 205 to intercept debris.

[0040] Dust control net 206 is made of polyethylene. Dust control net 206 made of polyethylene has the characteristics of high tensile strength, aging resistance and corrosion resistance, long service life and good interception effect.

[0041] The mounting slot 209 is adapted to the rotating gear 208 and the rack 210. Through the adaptation of the mounting slot 209 to the rotating gear 208 and the rack 210, both the rotating gear 208 and the rack 210 can operate inside the mounting slot 209.

[0042] The rotating gear 208 meshes with the rack 210, and the rack 210 is adapted to the slot 211. Through the meshing connection between the rotating gear 208 and the rack 210 and the adaptation between the rack 210 and the slot 211, the rotating gear 208 can drive the rack 210 to move when it rotates, and the rack 210 will be locked inside the slot 211 to help fix the recycling box 205.

[0043] The working process of this utility model is as follows: When using a dust removal device for a hammer mill, the operator first turns on the drive motor 203, which drives the fan 204 to rotate, thereby expelling the air inside the recycling tank 202. This generates suction to draw the splashed material debris into the recycling tank 202, where the debris is ultimately intercepted by the dust screen 206 and falls into the recycling box 205. After the hammer mill finishes working, the operator turns the rotating handle 207, which drives the rotating gear 208 to rotate as well. This causes the rack 210 to move and disengage from the slot 211, allowing the recycling box 205 to be easily removed and the debris to be recycled. Compared to existing dust removal devices for hammer mills, this device can recycle debris, preventing resource waste and eliminating the need for frequent filter replacements, making it more convenient.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
