Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an environmental engineering wastewater filtration and recovery device. Background Technology

[0002] Wastewater in environmental engineering refers to wastewater generated from various fields such as industry, agriculture, and domestic life. It includes various organic and inorganic pollutants such as heavy metals in the wastewater. If this wastewater is directly discharged into the environment, it will cause serious pollution to water bodies, soil, and air, endangering human health and ecological balance.

[0003] Existing technologies often have the following drawbacks: Wastewater in environmental engineering needs to be filtered during treatment. When wastewater is discharged into the sedimentation tank, it contains a large amount of garbage and impurities. Filtration is used to treat the wastewater and make it meet the discharge standards for recycling. The existing filtration method involves welding a filter screen to one end of the sewage pipe. Over time, this can cause garbage to accumulate in the sewage pipe, leading to blockage and affecting the filtration effect.

[0004] A search revealed a patent document with publication number CN 222489294 U, which discloses an environmental engineering wastewater filtration and recycling device. The device includes a sedimentation tank with a sewage pipe connected to one side. A filter structure is located at one end of the sewage pipe. The filter structure includes a rectangular box connected to the sewage pipe, with a drain pipe connected to one side. A filter box is placed on the inner wall of the rectangular box, and a rectangular hole is formed on the surface of the filter box. Bolts are threaded onto the surface of the filter box. A baffle is slidably connected to the inner wall of the rectangular hole. A rotating shaft is rotatably connected to the inner wall of the filter box, and several scrapers are fixedly connected to the arc surface of the rotating shaft. Two guide grooves are formed on the surface of the baffle, and a limit bracket is slidably connected to the inner wall of the guide grooves. This invention solves the problem of waste accumulation in the sewage pipe caused by welding a filter screen to one end of the sewage pipe in existing filtration methods.

[0005] While the aforementioned existing technologies address the current problems, they suffer from the problem of waste accumulating inside the filter box, which has a limited capacity and requires frequent cleaning, increasing workload. Therefore, this paper proposes an environmental engineering wastewater filtration and recovery device to optimize the existing technologies. Utility Model Content

A scraper chain 15 is connected to the second sprocket 14 for transmission. The scraper chain 15 corresponds to and is adapted to the filter screen plate 5.

[0026] Larger impurities are intercepted and transported to the side by the mesh conveyor belt 11, smaller impurities are filtered by the filter screen 5, and impurities are pushed to one side by the scraper chain 15. The impurities are filtered twice to reduce the risk of clogging. At the same time, the impurities are continuously transported to one side by the mesh conveyor belt 11 and the scraper chain 15 to avoid the accumulation of impurities, thereby effectively reducing the cleaning frequency.

[0027] Gears 16 are fixedly connected to one end of the first drive shaft 8 and the second drive shaft 12 respectively. The gears 16 mesh with each other for transmission. A motor 17 is provided on the outside of the gears 16. The motor 17 is fixedly connected to the side wall of the sewage treatment chamber 2. The motor 17 is a geared motor. The motor 17 is connected to a power supply and a switch.

[0028] Synchronous pulleys 18 are fixedly connected to the output end of motor 17 and one of the gears 16. The two synchronous pulleys 18 are connected by a synchronous belt 19.

[0029] The synchronous pulley 18 is driven to rotate by the motor 17. The synchronous pulley 18 is driven by the synchronous belt 19, which in turn drives the corresponding gear 16 to rotate. Through the cooperation of the gears 16, the first drive shaft 8 and the second drive shaft 12 can be driven to rotate synchronously. Under the action of the first sprocket 10 and the second sprocket 14, the mesh conveyor belt 11 and the scraper chain 15 are driven to run. Thus, the first drive shaft 8 and the second drive shaft 12 can be driven to run simultaneously by one motor 12.

[0030] The side wall of the sewage treatment chamber 2 is fixedly connected to a guide groove 20 below the running direction of the scraper chain 15. The guide groove 20 corresponds to both the scraper chain 15 and the mesh conveyor belt 11.

[0031] Impurities are collected below the scraper chain 15 and the mesh conveyor belt 11 via the guide groove 20 and then discharged to one side.

Through the engagement of gear 16, the first drive shaft 8 and the second drive shaft 12 are synchronously driven to rotate. Under the action of the first sprocket 10 on the first drive shaft 8 and the first driven shaft 9, the mesh conveyor belt 11 runs slowly. Under the action of the second sprocket 14 on the second drive shaft 12 and the second driven shaft 13, the scraper chain 15 runs slowly. Wastewater flows through inlet pipe 3. The wastewater is transported to the wastewater treatment chamber 2. The wastewater is collected in the conical converging cavity and falls onto the running mesh conveyor belt 11. Larger impurities remain on the mesh conveyor belt 11. The wastewater passes through the mesh conveyor belt 11 and falls onto the filter screen 5 for further filtration. The filtered wastewater enters the wastewater equalization tank 1 for collection. During the operation of the mesh conveyor belt 11, impurities are continuously transported to one side. At the same time, the scraper chain 15 continuously pushes the impurities on the filter screen 5 to one side during its operation. Finally, the impurities are guided to one side through the guide groove 20 to avoid the accumulation of impurities in the wastewater treatment chamber 2.
