[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1-5 ;

[0024] A slag removal device for environmental wastewater treatment includes a wastewater tank 1, a drain outlet 11 installed at one end of the wastewater tank 1 for draining wastewater from the wastewater tank 1, a slag removal mechanism 2 installed at the top of the wastewater tank 1 for removing slag from the environmental wastewater treatment tank, and a cleaning mechanism 3 installed in front of the wastewater tank 1 for cleaning the slag removal mechanism 2.

[0025] Furthermore, the slag removal mechanism 2 includes a support base 21, a reduction motor 22, and an L-shaped connecting plate 23. The support base 21 is fixedly installed at both ends of the wastewater tank 1, and is used to support the L-shaped connecting plate 23. The L-shaped connecting plate 23 is rotatably installed between the support bases 21. The reduction motor 22 is installed on the support base 21, and its output end is connected to one end of the L-shaped connecting plate 23. The reduction motor 22 drives the L-shaped connecting plate 23 to rotate, which in turn supports the rotation of the outer filter cover 24 and the inner filter cover 25. The outer filter cover 24 is bolted to the side wall of the L-shaped connecting plate 23. The bottom of the outer filter cover 24, like the side wall, is also a filter screen. The outer filter cover 24 is used to filter small particulate impurities. The inner filter cover 25 is installed inside the outer filter 24 by bolts. The inner filter cover 25 is used to filter large particulate impurities. After the inner filter cover 25 and the outer filter cover 24 are flipped 180 degrees, the impurities inside are poured out. Wastewater is first added into the inner filter cover 25 and filtered by the inner filter cover 25. Then the wastewater enters the outer filter cover 24 for filtration. The bottom of the inner filter cover 25 is set at an inclination, which not only allows for more space inside the outer filter cover 24, but also facilitates the pouring out of the impurities inside the outer filter cover 24. The side wall of the outer filter cover 24 is welded with a first support plate 26. When the outer filter cover 24 and the inner filter cover 25 are flipped and placed in the wastewater tank 1, the first support plate 26 rests on one side of the wastewater tank 1 to provide auxiliary support for the outer filter cover 24 and prevent instability after impurities accumulate inside the outer filter cover 24.

[0026] Furthermore, the cleaning mechanism 3 includes a first support 31 and a second support 311. The first support 31 is installed at one end of the wastewater tank 1, and the first support 31 and the second support plate 32 are used to support and install the first hydraulic cylinder 33. The second support 311 is installed at the other end of the wastewater tank 1, and the second support 311 and the third support plate 321 are used to support and install the second hydraulic cylinder 331. The second support plate 32 is installed on the first support 31, and the first hydraulic cylinder 33 is installed on the second support plate 32. The output end of the first hydraulic cylinder 33 is equipped with the first support plate 321. A top plate 34 has a water tank 35 installed on it. After water enters the water tank 35, it then flows into multiple connecting pipes 36. A third support plate 321 is installed on a second bracket 311, and a second hydraulic cylinder 331 is installed on the third support plate 321. The first hydraulic cylinder 33 and the second hydraulic cylinder 331 share a hydraulic device. The output ends of the first hydraulic cylinder 33 and the second hydraulic cylinder 331 simultaneously lift and lower to drive the connecting pipes 36 to adjust their height. This does not affect the rotation of the outer filter cover 24, but allows for spraying close to the outer filter cover 24. For water cleaning, a second top plate 341 is installed at the output end of the second hydraulic cylinder 331. The first top plate 34 and the second top plate 341 are used to connect and support the water tank 35 and the connecting pipe 36. A connecting pipe 36 is installed between the second top plate 341 and the water tank 35. A water outlet 361 is threaded onto the bottom of the connecting pipe 36. After water enters each connecting pipe 36, it is sprayed onto the outer filter cover 24 through the water outlet 361 to clean the outer filter cover 24, washing away small particulate impurities inside the outer filter cover 24. A water pump 37 is installed at one end of the wastewater pool 1. The water pump 37 is an ISW50-200(I)A water pump manufactured by Shanghai Quancheng Pump & Valve Manufacturing Co., Ltd. The water pump 37 is used to pump wastewater. Since the structure and operating principle of the water pump 37 are existing technologies, its structure and operating principle will not be described in detail here. A corrugated water pipe 371 is connected between the water pump 37 and the water tank 35. By setting the corrugated water pipe 371, the raising and lowering of the water tank 35 is not affected. The water pump 37 is used to pump wastewater from the wastewater pool 1 and transport it to the water tank 35 through the corrugated water pipe 371.

[0027] The working principle of this utility model is as follows: After the outer filter cover 24 and the inner filter cover 25 are flipped and placed into the wastewater tank 1, the first support plate 26 rests on one side of the wastewater tank 1 to provide auxiliary support for the outer filter cover 24, preventing instability after impurities accumulate inside the outer filter cover 24. Wastewater is first added into the inner filter cover 25, where large particles are filtered out. The wastewater then enters the outer filter cover 24 to filter out small particles. The bottom of the inner filter cover 25 is inclined, which not only allows for more space inside the outer filter cover 24 but also facilitates the removal of impurities from the outer filter cover 24. The reduction motor 22 drives the L-shaped connecting plate 23 to flip, and the L-shaped connecting plate 23 then supports the outer filter cover 24 and the inner filter cover 25 to flip 180 degrees. Impurities inside filter 24 and inner filter 25 are poured out. A slag-receiving container can be placed below the pouring position. The output ends of the first hydraulic cylinder 33 and the second hydraulic cylinder 331 simultaneously drive the connecting pipe 36 to descend and adjust the height of the water outlet 361. The water pump 37 draws wastewater from the wastewater pool 1 and transports it to the water tank 35 through the corrugated water pipe 371. After water enters the water tank 35, it enters multiple connecting pipes 36. After water enters each connecting pipe 36, it is sprayed onto the outer filter 24 through the water outlet 361 to clean the outer filter 24 and wash away small particulate impurities inside the outer filter 24. Then the connecting pipe 36 rises, and the outer filter 24 and inner filter 25 flip and reset to perform water injection filtration and impurity removal again.
