Further, sealing strips are installed at the corresponding positions of the box body 1 and the box cover 12, so that the filtering device is in a closed state when in use, and impurities are prevented from entering.
The other end of the first filter screen 2 extends into the box body 1, the chassis 3 is arranged on one end of the first filter screen 2 extending into the box body 1, and a first cavity 21 is formed between the box cover 12 and the inner wall of the first filter screen 2 and between the box cover and the chassis 3. A second cavity 22 is formed between the box body 1 and the outer wall of the first filter screen 2 and between the box body and the chassis 3. One end of a rotating shaft 8 penetrates through the top end of the box body 1 and is rotationally connected with the box body 1, and the other end of the rotating shaft 8 stretches into the first filter screen 2 and is rotationally connected with the chassis 3. Preferably, the rotating shaft 8 is rotatably connected to the top end of the housing 1 and the chassis 3 through a sealed bearing, so that the rotating shaft 8 is rotatably connected to the housing 1 and the chassis 3 while sealing the housing 1.
As described with reference to fig. 2, the scraper 7 is mounted on a rotating shaft 8 and is located in the first filter screen 2, and the rotating shaft 8 rotates to drive the scraper 7 to rotate relative to the first filter screen 2. In the present embodiment, the scraper 7 is mounted on the rotation shaft 8 by welding or integral molding to achieve fixed mounting of the scraper 7 and the rotation shaft 8, preventing the scraper 7 from falling off. The mixture enters the first cavity 21 through the feed inlet, the rotary shaft 8 rotates to drive the scraping plate 7 to rotate, the scraping plate 7 drives the mixture to rotate in the first cavity 21, in the process of rotating the mixture, extracting solution in the mixture enters the second cavity 22 from the first cavity 21 through the filter holes of the first filter screen 2, filter residues in the mixture cannot pass through the filter holes of the first filter screen 2, and then remain in the first cavity 21, so that the extracting solution and the filter residues are separated.

In addition, the scraping plate 7 is provided with holes, and the mixture moves at two sides of the scraping plate 7 through the holes formed in the scraping plate 7 while rotating along with the scraping plate 7 in the first cavity 21, so that the mixture is fully dispersed in the first cavity 21, the filtering efficiency is improved, and meanwhile, the filtering is more sufficient.
