Problems solved by technology
[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an oil removal and scum removal device for a sewage treatment plant to solve the problem that the prior art is highly dependent on manual operation and requires constant supervision by staff. It is easy to cause grease overflow. When the grease of sewage smart light is easy to adhere to the grille frame, the staff needs to clean the grille frame manually, but the trouble of grease cleaning will increase the labor intensity of the staff

Embodiment Construction
[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0026] Such as Figure 1-Figure 4 As shown, the present invention provides a kind of technical scheme of the degreasing and skimming device that sewage treatment plant is used:
[0027]An oil removal and scum removal device for a sewage treatment plant, its structure includes an upper cover plate 1, a sewage introduction pipe 2, an impurity cleaning tank 3, a bottom plate 4, an oil removal and scum removal device 5, a heater 6, and an air flotation device 7, The lower surface of the upper cover plate 1 is attached to the upper surface of the oil removal and scum removal device 5 and is connected by threads, and the rear surface of the sewage introduction pipeline 2 is connected to the right side surface of the oil removal and scum removal device 5...

The invention discloses an oil removal and skimming device for a sewage treatment plant. The oil removal and skimming device for the sewage treatment plant structurally comprises an upper cover plate,a sewage guiding-in pipe, an impurity cleaning tank, a bottom plate and an oil removal and skimming device body, wherein the lower surface of the upper cover plate is attached to the upper surface ofthe oil removal and skimming device body and is connected with the upper surface of the oil removal and skimming device body in a threaded manner; the rear surface of the sewage guiding-in pipe is connected with the surface of the right side of the oil removal and skimming device body; the impurity cleaning tank is mounted in the oil removal and skimming device in an embedded manner and sucks theoil removal and skimming device body; the impurity cleaning tank is arranged below the sewage guiding-in pipe; and the upper surface of the bottom plate is welded to the lower surface of the oil removal and skimming device body. When the device works and water level reaches to a certain height, an oil removal device beings to be started to remove oil from sewage, when the sewage flows, a grid frame can be cleaned to prevent grease from overflowing and prevent people from cleaning the grid frame manually, and thus, the use convenience of the oil removal and skimming device body is greatly improved.
Description
technical field [0001] The invention relates to the field of sewage treatment, more precisely, an oil removal and scum removal device for sewage treatment plants. Background technique [0002] Oil-water separation is mainly based on the density difference or chemical properties of water and oil, using the principle of gravity sedimentation or other physical and chemical reactions to remove impurities or complete the separation of oil and water. However, the oil removal and skimming device used in this sewage treatment plant has the following disadvantages: [0003] 1. The manual operation is highly dependent, and the staff needs to supervise it from time to time. Once the oil fishing personnel neglect management, it is easy to cause oil spillage. [0004] 2. When the grease of the sewage smart light is easy to adhere to the grill frame, the staff needs to manually clean the grill frame, but the grease cleaning is more troublesome and increases the labor intensity of the sta...
