Description

Technical Field

[0001] The utility model relates to the technical field of water pollution control, in particular to a device for controlling water pollution in urban rivers. Background Art

[0002] With the acceleration of urbanization, urban river water pollution refers to the direct or indirect introduction of substances or energy into the river environment due to human activities, which causes harmful effects such as damage to river biological resources, damage to river water and river environmental quality, and endangerment to human health. It is also a type of water pollution. Specifically, urban river water pollution is manifested in phenomena such as rising water temperature, rising river bacteria and microbial content, long-term suspension of river bottom sludge in the river, eutrophication of water bodies, and decreased biological production levels. Phenomena that people can intuitively distinguish include unpleasant river odors and turbid river water.

[0003] However, when the prior art is actually used, in the process of treating water pollution in urban rivers, a filter net or a filter grille is usually used to filter and clean the water in the urban river. However, when the filter net or the filter grille is used to filter and clean the garbage in the urban river water, the filtered garbage is easy to clog the filter net or the filter grille, so that the filter net or the filter grille needs to be salvaged and cleaned after a certain period of use, which makes the treatment of water pollution in urban rivers more cumbersome.

[0007] Preferably, the outer ends of the water inlet and the water outlet are respectively fixedly mounted with connecting flanges, so that the water inlet and the water outlet are connected to an external river sewage pipe through the connecting flanges.

[0008] Preferably, the upper end of the conveyor belt is tilted backward, and both side ends of the upper transmission roller are rotatably connected to the upper side of the rear end of the processing tank through a rotating shaft.

[0009] Preferably, there are several filter holes, which are symmetrically distributed at the outer ends of the conveyor belt, and there are several conveying teeth, which are symmetrically distributed at the outer ends of the conveyor belt.

[0010] Preferably, the rear end of the guide slide is inclined downward, the staggered teeth and the conveying teeth are staggered with each other, and the upper opening of the collection box is located directly below the lower end of the guide slide.

[0011] Preferably, the upper end of the filter screen plate is tilted backward and is fixedly connected to the front edge of the upper opening of the collection box.

[0012] Preferably, the upper and lower ends of the transmission screw are rotatably connected to the inner walls of the upper and lower ends of the straight slide groove through a rotating shaft, and the two sides of the sliding block are movably connected to the inner wall of the straight slide groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model introduces the required urban river sewage into the treatment tank through the water inlet. When the sewage is introduced into the sewage tank, the reduction motor is controlled to start, and the reduction motor drives the first sprocket to rotate. When the first sprocket rotates, the second sprocket is driven to rotate through the chain. When the second sprocket rotates, it drives the lower transmission roller to rotate. When the lower transmission roller rotates, it cooperates with the upper transmission roller to drive the conveyor belt to rotate and transport. When the conveyor belt rotates and transports, it drives the conveying teeth to transport upward. When the conveying teeth transport upward, the sewage and garbage in the treatment tank can be driven and transported upward. When the conveying teeth drive the sewage and garbage to be transported upward, the sewage can be filtered through the filtering holes to prevent a large amount of sewage from being transported upward with the sewage and garbage. At the same time, when the conveying teeth drive the sewage and garbage to be transported upward, the sewage and garbage transported upward by the conveying teeth can be intercepted at the upper end of the guide slide plate by the staggered teeth cooperating with the conveying teeth. When the sewage and garbage are intercepted at the upper end of the guide slide plate, they will slide into the collection box for collection due to the influence of their own gravity, thereby realizing the function of salvaging and collecting the garbage inside the sewage.

[0016] 2. The utility model also controls the submersible motor to be turned on when the filter screen plate performs secondary filtering on the sewage inside the treatment tank. When the submersible motor is turned on, it will drive the transmission screw to rotate. When the transmission screw rotates, it will drive the slider to move upward along the inner wall of the straight slide groove due to the force generated by the threaded connection with the outer curved surface in the middle part of the transmission screw. When the slider moves upward, it will drive the cleaning brush to move upward along the inner wall of the limiting slide groove. The limiting slide groove can play a linear limiting role in the upward movement of the cleaning brush. When the cleaning brush moves upward, it will scrape and clean the front end of the filter screen plate, and push the scraped and cleaned impurities to the upper opening of the collection box for collection. At the same time, the filtered and cleaned sewage will be discharged outward through the water outlet, thereby realizing the filtration and treatment of sewage while collecting the filtered garbage and impurities, avoiding the situation where the garbage and impurities inside the sewage will block the filter screen plate.

Staggered teeth 13 are provided at the front end of the guide slide 12, and the staggered teeth 13 and the conveying teeth 11 are staggered with each other. A collection box 14 is fixedly provided at the top end of the processing tank 1, and the upper end opening of the collection box 14 is located directly below the lower end of the guide slide 12.

[0025] When the control is turned on, the reduction motor 4 will drive the first sprocket 5 to rotate. When the first sprocket 5 rotates, the second sprocket 6 will be driven to rotate through the chain. When the second sprocket 6 rotates, the lower transmission roller 7 will be driven to rotate. When the lower transmission roller 7 rotates, it will cooperate with the upper transmission roller 9 to drive the conveyor belt 8 to rotate and convey. When the conveyor belt 8 rotates and conveys, it will drive the conveying teeth 11 to convey upward.

When the sewage inside the treatment tank 1 is subjected to secondary filtration treatment by the filter screen plate 15, the submersible motor 17 is turned on by control. When the submersible motor 17 is turned on, the transmission screw 18 is driven to rotate. When the transmission screw 18 rotates, the slider 19 is driven to move upward along the inner wall of the straight slide groove 16 due to the force generated by the threaded connection with the outer curved surface in the middle part of the transmission screw 18. When the slider 19 moves upward, the cleaning brush 20 is driven to move upward along the inner wall of the limiting slide groove 21.
