Before sewage treatment, various large-volume impurities in the sewage need to be removed before subsequent sewage purification treatment can be carried out.

[0003] Application number: CN202022161575.5 A sewage treatment equipment with an automatic oil scraper comprises a sewage pool, on which an oil scraper is provided, the oil scraper comprising an oil scraper assembly, a rotating roller, a transmission sheet, a transmission roller and a driving motor, an installation platform is provided on the sewage pool, a mounting frame is provided on the mounting platform, the rotating roller is arranged between the mounting frames, a transmission roller is arranged between the inner walls of the sewage pool, a transmission sheet is provided between the rotating roller and the transmission roller, and one end of the rotating roller is fixedly connected to the output end of the driving motor; the utility model effectively solves the problem of difficulty in removing oil stains on the surface of sewage in existing sewage treatment equipment, has fast oil scraping speed, good effect, high efficiency, and sufficient and thorough collection of oil stains, and has significant practicality.

[0004] The existing patented sewage treatment equipment uses a rotating roller and a transmission roller to drive the transmission sheet to rotate to collect and scrape the oil on the surface of the sewage. However, the roller body of this rotating roller is usually an integral stick body. When the transmission sheet outside the rotating roller needs to be removed for maintenance, the entire rotating roller needs to be removed from the mounting frame and the driving motor, which is not conducive to the disassembly and maintenance of the transmission sheet. For this reason, we propose a rotating roller for sewage filtration. Utility Model Content

The rotating roller that can be combined and disassembled is convenient for opening oppositely, so that the short roller body and the long roller body can be pulled out separately from the mounting frame, which greatly facilitates the opening of the rotating roller for sewage filtration and the disassembly and maintenance of the outer transmission plate of the rotating roller, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] Furthermore, the inner fixing blocks are symmetrically fixed in two groups on the outer ring wall of the inner embedded ring, and the inner fixing grooves are symmetrically opened in two groups on the inner wall of the long roller body;

[0011] By adopting the above technical solution, the inner ring and the inner fixing block can be adapted to be clamped in the inner fixing groove outside the long roller body.

[0012] Furthermore, the block size of the external fixing block is the same as the slot size of the external fixing slot, and the outer block surface of the external fixing block is set as an arc surface;

[0013] By adopting the above technical solution, the block body of the external fixing block can be adapted to be inserted into the external fixing groove, and then the external fixing block can contact the transmission sheet of the sewage treatment equipment by means of the arc surface.

[0014] Furthermore, the diameter of the inner ring is the same as the diameter of the inner roller cavity of the long roller body;
