DETAILED DESCRIPTION

[0031] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Embodiment 1:

[0034] A sewage treatment and reuse device, such as Figures 1 to 8 As shown, it includes a box body 1, and the inner walls on both sides of the box body 1 are respectively welded with a plug plate 14 and a plug plate 25, and an elastic member is fixed to the outer wall of one side of the plug plate 14, and a filter screen 13 is fixed to one end of the elastic member, a chute opened on the side wall of the filter screen 13 is slidably connected with a scraper 31, and a floating ball member is fixed to the side wall of the scraper 31, a trigger switch 7 is fixed to the top of the floating ball member, and a limit frame 6 used in conjunction with the trigger switch 7 is fixed to the top of the box body 1 by bolts, the chute opened on both sides of the box body 1 are slidably connected with a slide plate 9, a frame 32 is fixed between the two slide plates 9, and a rotating column 33 is rotatably connected to the two sides of the frame 32, and a flap 12 is fixed to the outer wall of the rotating column 33, a driving motor 8 is fixed to the outer wall of one side of the slide plate 9 by screws, and the output end of the driving motor 8 is connected to one end of the rotating column 33 through a coupling, a strong magnet 1 is installed inside the frame 32, and a strong magnet 2 is installed inside the scraper 31, and the magnetic poles of the strong magnet 1 and the strong magnet 2 are opposite;

[0035] When sewage needs to be treated, the sewage is first introduced into the box 1, and the particulate matter in the sewage can be filtered by the filter 13. The filtered sewage falls to the bottom of the box 1 through the filter 13. As the particulate matter filtered and retained on the filter 13 continues to accumulate, the particulate matter will eventually adhere to the filter 13, making it impossible for the sewage to pass through the filter 13 and fall to the bottom of the box 1. In this process, the sewage will continue to accumulate in the chamber between the plug plate 14 and the plug plate 25. As the liquid level of the sewage continues to rise, the float will gradually rise under the action of the buoyancy of the sewage, thereby driving the scraper The plate 31 moves upward synchronously, and the scraper 31 scrapes and cleans the particles attached to the filter screen 13 during the upward movement. At the same time, the scraper 31 uses the mutual attraction between the strong magnet 1 and the strong magnet 2 to drive the frame 32 to move upward synchronously during the upward movement. The frame 32 and the flap 12 temporarily block the cleaned filter screen 13 during the synchronous upward movement to prevent the particles on the filter screen 13 from being cleaned, causing the sewage to pass through the filter screen 13, causing the liquid level in the chamber between the plug plate 25 and the plug plate 1 14 to drop, causing the float to move downward, and finally causing the filter screen 13 to have a dead corner that cannot be completely cleaned;

[0036] When the scraper 31 moves to the top of the filter screen 13 to completely clean the particles on the filter screen 13, at this time, after the trigger switch 7 contacts the inner wall of the top of the limit frame 6, the trigger switch 7 is triggered and turned on to control the output end of the drive motor 8 to rotate. During the rotation of the output end of the drive motor 8, the flap 12 and the rotating column 33 are driven to rotate synchronously. After the flap 12 rotates, a relative opening is generated between the flap 12 and the frame 32, so that the sewage in the chamber between the plug plate 25 and the plug plate 1 14 is filtered by the filter screen 13 and finally enters the bottom of the box body 1 through the frame 32 for collection;

[0037] At the same time, the flap 12 impacts the surface of the filter 13 during the rotation process, and the filter 13 vibrates after receiving the impact, thereby further accelerating the falling of a small amount of particles attached to the surface of the filter 13, thereby improving the cleaning effect of the particles.

[0038] The elastic member includes a support plate 18, a sleeve 21 and a slide bar 22, wherein the support plate 18 is fixed to the outer wall of one side of the plug plate 14 by bolts, and the sleeve 21 is welded to the outer wall of one side of the support plate 18, and the slide bar 22 is slidably connected to the inner wall of the through hole opened at one end of the sleeve 21, and the end of the slide bar 22 away from the sleeve 21 is fixedly connected to the filter screen 13, and a spring 34 is clamped between one end of the slide bar 22 and the inner wall of one side of the sleeve 21;

[0039] The sleeve 21 and the slide bar 22 can guide the movement path of the filter 13 after the filter 13 is impacted by the flap 12, and the spring 34 can ensure that the filter 13 can be reset after the flap 12 and the filter 13 are separated.

[0040] The float member includes a connecting plate 27 and a transverse plate 28, the transverse plate 28 is welded to one end of the scraper 31, and the connecting plate 27 is welded to the top outer wall of the transverse plate 28, and the float body 26 is fixed to the top of the connecting plate 27, and a lifting rod 20 is fixed to the top of the float body 26, and the lifting rod 20 is fixedly connected to the trigger switch 7;

[0041] The float body 26 can be provided to drive the scraper 31 upward under the buoyancy of the sewage to clean the particles on the filter screen 13 .

[0042] A water inlet pipe 5 is welded to the outer wall of the top of the box body 1, and a drain pipe 2 is welded to the outer wall of one side of the box body 1;

[0043] By providing a water inlet pipe 5, sewage to be treated can be introduced into the chamber between the plug plate 1 14 and the plug plate 2 25, and by providing a drain pipe 2, the filtered sewage can be discharged.

[0044] The top of the plug plate 25 is provided with a conical hole 23, and the bottom of the plug plate 25 is welded with a guide pipe 11, and the guide pipe 11 and the conical hole 23 are connected to each other. The top of the plug plate 25 is welded with a lining plate 24, and the top of the lining plate 24 is welded with a triangular plate 19. The bottom of the scraper 31 is welded with a guide plate 30, and the lifting rod 20 and the lining plate 24 are slidably connected. The surface of the guide plate 30 is provided with a rectangular hole 29 used in conjunction with the conical hole 23;

[0045] The inner wall of the top of the box body 1 is rotatably connected with a rotating tube 15, and a nozzle 17 is welded to the outer wall of the rotating tube 15, and a joint is fixed at one end of the rotating tube 15;

[0046] When the sewage treatment is completed, the filtered and trapped particles will accumulate in the chamber between the plug plate 14 and the plug plate 25. When the particles need to be cleaned, the driving motor 8 is used to drive the flap 12 and the rotating column 33 to rotate. The flap 12 gradually squeezes the filter screen 13 during the rotation. After the filter screen 13 is squeezed, the scraper 31 and the guide plate 30 are driven to move laterally. During the lateral movement of the guide plate 30, a relative opening is gradually generated between the rectangular hole 29 and the conical hole 23. At this time, the rotating tube 15 and the pipeline are connected through a joint, so that the rotating tube 15 and the nozzle 17 spray clean water to flush the inside of the chamber, and the waste liquid after flushing is discharged through the conical hole 23 and the outlet pipe 11.

[0047] When the present embodiment is in use, the sewage is first introduced into the chamber between the plug plate 1 14 and the plug plate 2 25 by using the water inlet pipe 5. After the particulate matter in the sewage is filtered by the filter screen 13, the particulate matter passes through the filter screen 13 and enters the bottom of the box body 1, and is finally discharged through the drain pipe 2. As the sewage is continuously filtered, the particulate matter attached to the filter screen 13 will gradually accumulate. When the particulate matter filtered and intercepted on the filter screen 13 continues to accumulate, the particulate matter will eventually adhere to the filter screen 13, making it impossible for the sewage to pass through the filter screen 13 and fall to the bottom of the box body 1. In this process, the sewage will continue to accumulate in the chamber between the plug plate 14 and the plug plate 25. As the liquid level of the sewage continues to rise, the float will gradually rise under the action of the buoyancy of the sewage, thereby driving the scraper 31 to move upward synchronously. During the upward movement, the scraper 31 scrapes and cleans the particulate matter attached to the filter screen 13.

[0048] Embodiment 2:

[0049] A sewage treatment and reuse device, such as Figures 1 to 8 As shown, in order to improve the flushing range of the chamber between the plug plate 14 and the plug plate 25, this embodiment makes the following supplements on the basis of the embodiment 1: the reel 2 10 is fixed to one end of the rotating column 33 by screws, and the reel 1 4 is fixed to one end of the rotating tube 15 by screws, and the reel 1 4 and the reel 2 10 are connected by a driving belt 3, and a torsion spring 16 is clamped between the end of the rotating tube 15 away from the reel 1 4 and the box body 1;

[0050] The two ends of the driving belt 3 are respectively wound around the outer circumferential walls of reel 2 10 and reel 1 4. Therefore, when the driving motor 8 drives the rotating column 33 to rotate, the transmission action of the driving belt 3 is utilized to make reel 1 4 drive the rotating tube 15 and the nozzle 17 to perform a swiveling motion, thereby increasing the flushing range of the nozzle 17. The torsion spring 16 is utilized to ensure that the driving belt 3 is always in a tensioned state. By changing the ratio of the outer diameters of reel 2 10 and reel 1 4, the swing range of the rotating tube 15 and the nozzle 17 is adjusted.

[0051] The above is a preferred specific implementation manner of the present invention, and the protection scope of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
