DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] A treatment device for sewage treatment and cleaning, comprising a box body 1, wherein a cover plate 2 is arranged on the top of the box body 1, and a feed port is arranged in the middle of the cover plate 2:

[0025] A circle of surrounding edges 3 is arranged in the box body 1, wherein a grid plate 4 is arranged in the cavity between the surrounding edges 3 and the side wall of the box body 1 to separate it into a filter chamber 5 and a sewage discharge chamber 6, and the filter chamber 5 is located above the sewage discharge chamber 6, the side wall of the surrounding edges 3 above the grid plate 4 is a hole-shaped structure, and sewage discharge ports 7 connected to the sewage discharge chamber 6 are evenly arranged on the upper half of the side wall of the surrounding edges 3 below the grid plate 4, wherein a circle of grooves for accommodating sealing strips 8 is arranged on the inner wall of the surrounding edges 3 above the sewage discharge port 7;

[0026] A support plate 9 flush with the grid plate 4 is arranged in the surrounding edge 3, wherein a screw tube 110 is arranged in the middle of the support plate 9, and a rolling bearing 11 is arranged on the outer sleeve of the screw tube 110, and a support ring 12 is arranged on the bottom end of the rolling bearing 111, wherein a gear ring 13 is arranged on the outer sleeve of the rolling bearing 11 above the support ring 12, and a scraper rod 14 located on the top surface of the support plate 9 is also radially arranged on the outer wall of the support ring 12, and a skirt 15 is also arranged at the bottom of the support plate 9 to seal the sewage outlet 7, wherein a slide groove 16 is axially arranged on the inner wall of the skirt 15, and a roller group 17 is arranged in the slide groove 16, wherein the roller group 17 is fixedly connected to a vertical rod 18 fixed on the inner bottom wall of the box body 1;

[0027] A motor 19 is provided at the bottom of the box body 1, wherein a forward and reverse screw rod 20 passing through a screw tube I10 is provided on the output shaft of the motor 19, and a protrusion 21 located between the forward thread and the reverse thread of the forward and reverse screw rod 20 is provided on the rod body, and the protrusion 21 is located above the support plate 9, and a circular ring 22 abutting against the inner wall of the surrounding edge 3 is provided below the cover plate 2, wherein a bracket 23 is provided in the opening of the circular ring 22, and a screw tube II24 for the forward and reverse screw rod 20 to pass through is provided on the bracket 23. In this embodiment, an L-shaped rod 28 is provided on the top of the cover plate 2, wherein a rolling bearing II for fixing the top of the forward and reverse screw rod 20 is provided on the L-shaped rod 28.

[0028] A cross bar 25 is provided at the bottom of the forward and reverse screw rods 20 above the protrusion 21, wherein a gear 27 located above the support ring 12 is fixed to the bottom of the cross bar 25 through a telescopic rod 126, and the gear 27 is meshed with the gear ring 13.

[0029] like Figure 2 , 3 As shown, a telescopic rod II29 connected to the bracket 23 is provided on the cover plate 2, and a telescopic rod III30 connected to the support plate 9 is provided at the bottom of the box body 1. When the ring 22 and the support plate 9 move up and down, the telescopic rod II29 and the telescopic rod III30 can be extended and retracted at the same time to prevent them from affecting the movement of the above components, and can also prevent the above components from rotating when they move.

[0030] In this embodiment, the distance between the skirt 15 and the bottom of the box body 1 is greater than the distance between the vertical rod 18 and the support plate 9, wherein the top end of the vertical rod 18 is located below the sewage outlet 7, and the distance between the top end of the vertical rod 18 and the bottom end of the sewage outlet 7 is equal to the thickness of the support plate 9.

[0031] In this embodiment, a V-shaped tube 31 communicating with the filter chamber 5 is arranged on the grid plate 4 , wherein a solenoid valve is arranged on the V-shaped tube 31 , and an outlet end of the V-shaped tube 31 is arranged to be inclined downward toward the corresponding sewage outlet 7 .

[0032] In this embodiment, a receiving groove 32 is provided at the inner bottom of the surrounding edge 3 to receive a small amount of liquid that may seep through the gap between the skirt edge 15 and the surrounding edge 3 and then be discharged through a pipeline.

[0033] In this embodiment, a flow guide hopper 33 is provided on the inner wall of the box body 1 and is located in the upper opening of the filter cavity 5 , wherein a liquid guide port is formed between the bottom opening end of the flow guide hopper 33 and the side wall of the surrounding edge 3 .

[0034] In this embodiment, a scraper ring 34 in contact with the inner wall of the surrounding edge 3 is provided between the support plate 9 and the circular ring 22 , wherein the scraper ring 34 and the support plate 9 are connected by connecting rods 35 , and the scraper rods 14 are located in the opening formed by multiple groups of connecting rods 35 .

[0035] The working principle of the present invention is as follows: sewage is introduced into the surrounding edge 3 above the support plate 9 through the feed port, and filtered by the apertures on the side wall of the surrounding edge 3. The filtered liquid flows into the filter cavity 5 and can be discharged from the outlet pipe on its side wall, thereby achieving the purpose of treating sewage. In the above process, the sealing strip 8 can prevent the liquid above the support plate 9 from seeping downward along the gap that may exist between the skirt 15 and the solid side wall of the surrounding edge 3.

[0036] When the pores on the side wall of the surrounding edge 3 may be blocked by the impurities obtained by filtration, Figure 2 As shown, the motor 19 drives the forward and reverse screw rods 20 to rotate forwardly in the screw tubes I10 and II24, thereby driving the support plate 9 to move upward through the screw tube I10. At this time, the telescopic rod III can be stretched so that it does not affect the movement of the support plate 9 and can also prevent it from rotating, and the support plate 9 also drives the scraper ring 34 to move upward through the connecting rod 35. At the same time, the screw tube II24 driven by the forward and reverse screw rods 20 will drive the ring 22 to move downward through the bracket 23. At this time, the telescopic rod II29 can be stretched so that it does not affect the movement of the ring 22 and can also prevent it from rotating. Then the forward and reverse screw rods 20 are reversed to drive the support plate 9 and the scraper ring 34 to move downward through the screw tubes I10 and II24, driving the ring 22 to move upward, and then the above-mentioned components are moved up and down on the inner wall of the surrounding edge 3 to adhere to its side The filtered impurities on the wall are cleaned. In the above process, the circular ring 22, the scraper ring 34 and the support plate 9 that move up and down can cover the entire side wall area used for filtering in the surrounding edge 3 to improve the cleaning efficiency. At the same time, when the positive and negative wires 20 rotate, the gear 27 will be driven to rotate through the cross bar 25 and the telescopic rod 126, so that it drives the gear ring 13 to rotate on the rolling bearing 11 while driving the support ring 12 and the scraper rod 14 to rotate, so that the scraper rod 14 can scrape off the silt that may exist on the top surface of the support plate 9, and as the support plate 9 moves up or down, it will press against the gear 27 through the support ring 12 to force the telescopic rod 126 to contract, or stretch the telescopic rod 126, thereby preventing the telescopic rod 126 and the gear 27 and other components from affecting the up and down movement of the support plate 9.

[0037] In the above process, when the support plate 9 moves upward, the skirt 15 will be driven to move, so that the skirt 15 can seal the apertures on the side wall of the surrounding edge 3 below the support plate 9 at this time, to prevent liquid in the filter chamber 5 from penetrating into the lower part of the support plate 9 through the apertures on the side wall of the surrounding edge 3. At the same time, the surrounding edge 3 will drive the slide groove 16 to slide on the roller group 17, so that the skirt 15 and the side wall of the surrounding edge 3 are more closely fitted under the squeezing influence of the roller group 17, thereby reducing the gap between the two to improve the sealing performance, and at the same time, the side wall of the skirt 15 is supported and fixed at multiple points to prevent its deformation.

[0038] In the above process, when the support plate 9 moves upward, the liquid that may exist above it can be driven to surge upward, and part of it flows into the filter chamber 5 through the aperture of the surrounding edge 3. Since the aperture of the side wall above the surrounding edge 3 does not adhere to impurities due to the scraping effect of the ring 22, the remaining part of the liquid surges up and flows into the filter chamber 5 through the aperture of the side wall of the surrounding edge 3 that has been cleaned above the ring 22. At this time, this part of the liquid flows into the top of the guide bucket 33 and is guided by it, and then flows from the liquid diversion port to the outer wall of the surrounding edge 3 and flows down, so that it can flush and clean the outer wall of the surrounding edge 3.

[0039] After the impurities adhering to the aperture of the side wall of the peripheral edge 3 are cleaned by the circular ring 22, the scraper ring 34 and the support plate 9 moving up and down, the rotating scraper rod 14 scrapes and cleans the impurities that may exist above the support plate 9. Figure 3 As shown, the forward and reverse screw rods 20 drive the support plate 9 to move down to the bottom of the sewage outlet 7 and be supported by the vertical rod 18 to prevent it from moving further down, thereby playing a supporting and limiting role. At the same time, the impurities cleaned above the support plate 9 will flow into the sewage chamber 6 through the sewage outlet 7 and finally be discharged from the sewage pipe. At the same time, the residual liquid in the filter chamber 5 flows into the surrounding edge 3 through the side wall aperture of the surrounding edge 3 to flush the top surface of the support plate 9, so that the liquid and the impurities cleaned are smoothly mixed and then flow into the sewage chamber 6 through the sewage outlet 7 to play a sewage cleaning role. In the above process, a sealing ring can be provided on the inner wall of the surrounding edge 3 below the sewage outlet 7 to prevent liquid from seeping down, and the V-shaped tube 31 can also be opened to allow the liquid in the filter chamber 5 to spray downward therethrough to flush the sewage outlet 7, thereby preventing the impurities discharged from the support plate 9 through the sewage outlet 7 from clogging it, thereby playing a backwashing role.

[0040] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
