Description

Technical Field

[0001] This utility model relates to the field of oil removal technology in sewage treatment, specifically to an oil removal mechanism for sewage treatment. Background Technology

[0002] Domestic sewage often contains a large amount of solid waste and oil and other debris. During sewage treatment, it is necessary to separate the solid residue and oil from the sewage.

[0003] Current separation devices are all set up separately. They filter the residue through filter screens and then introduce the wastewater into a settling tank, where the oil floats on the surface of the liquid. Then, they use scrapers and other structures to scrape off the oil. This treatment method is inefficient.

[0004] Therefore, we propose a wastewater treatment residue and oil separation device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil removal mechanism for wastewater treatment, which solves the problem mentioned in the background art where oil floats on the surface of the liquid and is then scraped off using a scraper or similar structure, resulting in low efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil removal mechanism for sewage treatment, comprising a treatment box, a horizontal plate slidably connected to the outer wall of the treatment box, an L-shaped scraper slidably connected to the inside of the horizontal plate, two bolts threadedly connected to the inside of the horizontal plate, an electric telescopic rod fixedly installed on the outer wall of the treatment box, a partition plate fixedly installed inside the treatment box, a rotating shaft rotatably connected to the inside of the treatment box, a pressure plate slidably connected to the inside of the treatment box, a limit plate fixedly installed on the left outer wall of the partition plate, two U-shaped plates fixedly installed on the outer wall of the treatment box, torsion springs fixedly installed on the side of each U-shaped plate near the treatment box, two sliding frames fixedly installed inside the treatment box, and oil-water separation filter elements slidably connected inside the two sliding frames.

[0007] Preferably, a plug is fixedly installed on the outer wall of the oil-water separator filter element, and a handle is fixedly installed on the side of the plug away from the oil-water separator filter element. Three water outlet pipes are fixedly inserted into the inside of the treatment box.

[0008] Preferably, a sealing ring is fixedly installed on the outer wall of the plug, and the outer wall of the sealing ring is in close contact with the interior of the processing box.

[0009] Preferably, each of the three water outlet pipes is fixedly installed with a solenoid valve, and the outer wall of the oil-water separator filter element is movably fitted with the right outer wall of the separator plate.

[0010] Preferably, the two ends of the rotating shaft are fixedly welded to the outer walls of two torsion springs, and the outer wall of the rotating shaft is fixedly installed inside the pressure plate.

[0011] Preferably, the outer wall of the rotating shaft is movably fitted with the outer wall of the partition plate, and the outer wall of the pressure plate is movably fitted with the outer wall of the limiting plate.

[0012] Preferably, the right outer wall of the horizontal plate is fixedly connected to the output ends of the two electric telescopic rods, and the outer wall of the L-shaped scraper is movably fitted with the outer walls of the two bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The oil removal mechanism for wastewater treatment uses an electric telescopic rod to move the horizontal plate to the right, collecting the oil between the L-shaped scraper and the pressure plate.
