Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recovery, in particular to a wastewater recovery device for metal dust removal. Background Art

[0002] Metal is a substance that has lustre (i.e. strong reflection of visible light), is ductile, and is easy to conduct electricity and heat. The above properties of metals are all related to the free electrons contained in metal crystals. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state.

[0003] When metal products are placed for a long time, a lot of dust will accumulate on their surface. When dealing with the dust, water resources are generally used to rinse it. However, the existing wastewater recycling generally sets up a filter. After long-term filtration, a large amount of impurities will accumulate on the surface of the filter, and the impurities will clog the mesh. If it is not cleaned, it will affect the subsequent filtration. Some cleaning devices can only scrape off the impurities, but cannot remove the impurities and collect the impurities in a centralized manner, which brings trouble to people. Utility Model Content

A handwheel 8 is provided at the end of one of the threaded rods 6. By rotating the two threaded rods 6 and utilizing the threaded connection between the scraper 19 and the two threaded rods 6, the scraper 19 is moved to scrape off impurities on the filter screen 17 to prevent impurities from clogging the filter screen 17 and affecting subsequent filtration.

[0024] A through channel 18 is provided at the front end of the box body 1, and the through channel 18 cooperates with the filter screen 17. A cover plate 9 is provided at the front end of the box body 1, and the cover plate 9 cooperates with the through channel 18.
