Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, to a negative pressure dust removal device for workshop dust. Background Technology

[0002] Workshop dust refers to fine solid particulate matter suspended in the air generated during industrial production processes such as processing, cutting, grinding, spraying, welding, and handling. The type, concentration, and composition of dust vary depending on the production industry and process. Dust not only affects workshop air quality but can also impact worker health and safety, as well as equipment operation.

[0003] Some powder processing workshops are major sources of dust pollution, especially during the process of feeding materials into containers. Generally, negative pressure dust removal equipment is used to absorb the dust raised during feeding. The suction end of the dust removal device is usually a funnel-shaped frame, but the frame is fixedly installed on the outside of the feed inlet. The dust collected inside the dust removal equipment is not easy to clean in a timely manner, and long-term use can easily lead to blockage. Furthermore, it is not easy to quickly recycle and reuse the collected dust. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a negative pressure dust removal device for workshop dust, which has the advantages of rapid cleaning and recycling of collected dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure dust removal device for workshop dust, comprising a support assembly and a negative pressure fan assembly.

A cylindrical rod 303 is movably sleeved in the middle of the side of the long strip plate 302. A cleaning plate 304 is fixedly connected to the right side of the cylindrical rod 303. Brush bristles 305 are provided on the surface of the right side of the cleaning plate 304, and the brush bristles 305 are in contact with the surface of the filter screen 301.

[0023] In this embodiment, after the negative pressure pipe 201 is activated, the opening of the negative pressure frame 3 generates negative pressure, thereby collecting the dust generated when adding materials and preventing the dust from polluting the workshop environment. The filter screen 301 plays a filtering role. The collected dust adheres to the surface of the filter screen 301. After long-term use of the dust removal equipment, a large amount of dust will adhere to the surface of the filter screen 301, which will affect the efficiency of negative pressure dust removal and increase the energy consumption of the wind power system. By rotating the threaded rod 401 through the crank 403, the threaded rod 401 and the fixed Under the thrust of the threaded rod 401, the threaded rod 401 pushes the support plate 402 to move horizontally to the left, thereby placing the negative pressure frame 3 above the feeding port. Then, the motor 602 is started to drive the active rotating wheel 603 to rotate. Through the transmission of the belt 604, the driven rotating wheel 306 drives the cylindrical rod 303 to rotate, thereby rotating the cleaning plate 304. The bristles 305 can clean the surface of the filter screen 301. The dust that is cleaned falls into the inside of the feeding port under the action of gravity, realizing the recycling of dust.

[0032] Working principle and usage process of this utility model:

[0033] After the negative pressure pipe 201 is activated, the opening of the negative pressure frame 3 generates negative pressure, which can collect the dust generated when adding materials, preventing the dust from polluting the workshop environment. The filter screen 301 plays a filtering role. The collected dust adheres to the surface of the filter screen 301. After long-term use of the dust removal equipment, a large amount of dust will adhere to the surface of the filter screen 301, which will affect the efficiency of negative pressure dust removal and increase the energy consumption of the wind power system. By rotating the threaded rod 401 through the crank 403, the threaded rod 401 and the fixed plate 101 are connected. Under the thrust of the threaded rod, the threaded rod 401 pushes the support plate 402 to move horizontally to the left, thereby placing the negative pressure frame 3 above the feeding port. Then, the motor 602 is started to drive the active rotating wheel 603 to rotate. Through the transmission of the belt 604, the driven rotating wheel 306 drives the cylindrical rod 303 to rotate, thereby rotating the cleaning plate 304. The bristles 305 can clean the surface of the filter screen 301. The dust that is cleaned falls into the inside of the feeding port under the action of gravity, realizing the recycling of dust.
