[0002] Oil extraction refers to the act of digging and extracting oil from a place where oil is stored. When oil is extracted, oil is extracted through drilling, and mud will appear during drilling. At this time, filtering equipment is needed to filter the mud to filter out the gravel contained in it;

[0003] When using the existing drilling mud filtration equipment for oil mining, the mud to be filtered is usually poured directly onto the filter screen and wait for filtration. In actual use, we found that the efficiency of this filtration method is low. At the same time, during the filtration process, gravel will accumulate on the filter screen and cause the filter holes to be blocked, which will affect the actual filtration efficiency. Therefore, how to solve this problem is what we need to consider. Utility Model Content

The circular filter plate 7 is in contact with the inner wall of the first inner groove 6. The upper end of the circular filter plate 7 is provided with a plurality of filter holes 8, and the filter holes 8 can separate the mud and the gravel. A sleeve 9 is provided through the inner bottom of the first inner groove 6. The sleeve 9 is rotatably connected to the lower end of the lower shell 1. The upper end of the sleeve 9 is fixedly connected to the lower end of the circular filter plate 7. A motor 11 is installed at the lower end of the lower shell 1. 9 is rotatably connected with a first rotating shaft 10, the upper end of the first rotating shaft 10 penetrates the circular filter plate 7, the lower end of the first rotating shaft 10 is fixedly connected to the output shaft of the motor 11, and the upper end of the first rotating shaft 10 is provided with a scraping assembly, which includes a scraper 18 fixedly connected to the first rotating shaft 10, and a steel brush 19 is provided at the lower end of the scraper 18. The steel brush 19 fits with the upper end of the circular filter plate 7 and can effectively scrape the gravel on the upper end of the circular filter plate 7, thereby preventing the gravel from blocking the filter hole 8 during the filtering process and affecting the filtering efficiency of the mud. The lower end of the lower housing 1 is rotatably connected with a second rotating shaft 12;

[0024] The lower end of the sleeve 9 is connected to the second rotating shaft 12 through a first transmission assembly, and the first transmission assembly includes a first gear 13 fixedly connected to the lower end of the sleeve 9, and a second gear 14 is fixedly connected to the upper end of the second rotating shaft 12, and the first gear 13 and the second gear 14 are meshed;
