Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-5 , low environmental impact PE pipe production wastewater treatment device, including filter tank 1, the inside of filter tank 1 is slidably provided with filter plate 2, the top of filter tank 1 is fixedly connected with support 3, support 3 is rotatably connected with connecting shaft 4, one side of support 3 is provided with winch 5, one end of connecting shaft 4 is connected with the output shaft of winch 5, winch 5 can drive connecting shaft 4 to rotate forward or reversely after starting, two groups of roller 6 are fixedly sleeved on connecting shaft 4, traction rope 7 is wound on roller 6, the end of traction rope 7 extends downward and is fixedly connected on both sides of the top of filter plate 2, connecting shaft 4 drives two groups of roller 6 to rotate forward or reversely, and at the same time, two groups of roller 6 can synchronously drive traction rope 7 wound thereon to elongate or shorten, so that filter plate 2 in filter tank 1 can be lifted or lowered under the driving of traction rope 7 on both sides, two groups of slide bar 8 are fixedly connected on support 3, scraper 9 is arranged between two groups of slide bar 8, slide sleeve 10 is fixedly connected on both sides of scraper 9, slide sleeve 10 is respectively slidably sleeved on the surface of two groups of slide bar 8, when scraper 9 is driven, it will slide in the horizontal and linear direction under the guidance of slide bar 8 and slide sleeve 10, reciprocating driving assembly is arranged between support 3 and scraper 9, reciprocating driving assembly can produce horizontal reciprocating driving action on scraper 9, so as to drive scraper 9 to continuously slide horizontally and reciprocally between two groups of slide bar 8.

[0024] The top and bottom ends of the filter tank 1 are provided with water injection pipes and drainage pipes. In use, the wastewater after coagulation treatment is injected into the filter tank 1 through the water injection pipes. The filter plate 2 in the filter tank 1 is located at a height position between the water injection pipes and the drainage pipes. The filter plate 2 can filter and intercept the particulate impurities in the wastewater. The filtered wastewater flows to the bottom of the filter tank 1 through the filter holes on the filter plate 2 and is then discharged from the drainage pipes at the bottom of the filter tank 1. Thus, the wastewater after coagulation can be effectively filtered. The particulate impurities in the wastewater will gradually accumulate on the surface of the filter plate 2. When the accumulated impurities on the filter plate 2 are relatively large, the winch 5 is started to drive the two groups of rollers 6 to rotate, so that the traction rope 7 wound on the rollers 6 is shortened, thereby pulling the filter plate 2 in the filter tank 1 to move upward. When the filter plate 2 moves to the level of the top surface of the filter tank 1, the scraper 9 abuts against the surface of the filter plate 2. At this time, the scraper 9 sliding between the two connecting shafts 4 is driven by the reciprocating drive assembly to move horizontally and reciprocally. The scraper 9 abutting against the filter plate 2 can automatically scrape the particulate impurities accumulated on the surface of the filter plate 2 to the two sides of the filter tank 1 during the horizontal reciprocating movement, so that the staff can clean the impurities outside the filter tank 1. Thus, the filter water holes of the filter plate 2 are prevented from being blocked by the accumulation of too much impurities, and the wastewater discharged into the filter tank 1 is prevented from overflowing the filter tank 1 due to the inability to smoothly pass through the filter plate 2, thereby affecting the surrounding environment. After cleaning, the winch 5 is started to drive the two groups of rollers 6 to rotate, so that the traction rope 7 wound on the rollers 6 is elongated. The filter plate 2 will slide downward to reset in the filter tank 1 under the action of gravity.

[0025] Further, please refer to Figure 3 The reciprocating drive assembly includes a motor 11 mounted on the support 3, an arm rod 12 connected to one end of the output shaft of the motor 11, a plug column 13 provided at the end of the arm rod 12, and a strip-shaped slot 14 provided at the top end of the scraper 9 for the one end of the plug column 13 to be inserted. When the output shaft of the motor 11 drives the arm rod 12 to rotate, the plug column 13 at the end of the arm rod 12 also rotates around the motor 11 as the central axis. During the rotation, the one end of the plug column 13 always remains inside the strip-shaped slot 14 at the top end of the scraper 9 and moves reciprocally along the inside of the strip-shaped slot 14. In this process, the plug column 13 will produce a horizontal reciprocating driving effect on the scraper 9, driving the scraper 9 to slide horizontally and reciprocally under the guidance of the sliding rod 8 and the sliding sleeve 10.

[0026] Further, please refer to Figure 2 The bottom end of the filter plate 2 is provided with counterweights 21. The two groups of counterweights 21 are connected to the two sides of the bottom end of the filter plate 2. The two groups of counterweights 21 can increase the weight of the filter plate 2. When the filter plate 2 is controlled to move downward, the sidewall of the filter plate 2 can be prevented from being stuck in the filter tank 1, ensuring that the filter plate 2 can smoothly move downward and effectively preventing the filter plate 2 from floating upward under the action of the buoyancy of the water in the filter tank 1.

[0027] Further, please refer to Figure 1 and Figure 4 , the top of the filter tank 1 both sides are provided with sewage inclined plate 15, the bottom of the filter tank 1 is located below the sewage inclined plate 15 is provided with sewage tank 16, the particles impurities cleaned from the filter plate 2 surface will be through the sewage inclined plate 15 slide to the bottom of the filter tank 1 both sides inside the sewage tank 16, for people to concentrate on processing, can avoid the impurities contact to the surface of the filter tank 1 caused by pollution.

[0028] Further, please refer to Figure 5 , the upper end of the inner wall of the filter tank 1 is provided with upper baffle 17, the middle of the inner wall of the filter tank 1 is provided with lower baffle 18, the upper baffle 17 and the lower baffle 18 limit the stroke of the filter plate 2 up and down, when the filter plate 2 is moved up to the position of the top surface of the filter tank 1 flush, its edge will be in contact with the upper baffle 17, at this time under the limiting effect of the upper baffle 17, the filter plate 2 cannot continue to move up, can avoid the filter plate 2 up to the outside of the filter tank 1, when the filter plate 2 is moved down to the middle position of the filter tank 1, its edge will be in contact with the lower baffle 18, at this time the lower baffle 18 can limit the filter plate 2 continue to move down.

[0029] Further, please refer to Figure 2 , Figure 4 and Figure 5 , the inner wall of the filter tank 1 is vertically provided with a plurality of groups of guide strips 19, the edge of the filter plate 2 is provided with a plurality of groups of guide grooves 20 matched with the guide strips 19, the guide strips 19 and the guide grooves 20 are matched with each other, so that the filter plate 2 can always keep horizontal state without deflection in the process of sliding up and down.
