[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3, the present utility model provides a technical solution: an environment-friendly sewage treatment device, including a storage tank 1, a transition tank 15, and a dirt accumulation tank 16 fixedly connected in sequence from left to right. On the left and right sides above the storage tank 1, a filtering chamber 2 and a cleaning chamber 3 which are interconnected are fixedly connected respectively. The lower ends of the filtering chamber 2 and the cleaning chamber 3 are respectively communicated with the storage tank 1. A baffle 4 is slidably connected in the cleaning chamber 3 along the vertical direction. The front and rear ends of the baffle 4 are respectively slidably connected with the front and rear inner side walls of the cleaning chamber 3. A first filter screen plate 8 is horizontally slidably connected in the filtering chamber 2. On the left side of the filtering chamber 2, a second filter screen plate 9 on the same plane as the first filter screen plate 8 is provided. The left end of the first filter screen plate 8 is fixedly connected with the right end of the second filter screen plate 9. The first filter screen plate 8 and the second filter screen plate 9 have the same structure. A driving mechanism is fixedly connected to the left side of the filtering chamber 2. The driving mechanism is in transmission connection with the second filter screen plate 9. A through hole 14 penetrates through the left side wall of the transition tank 15. A plug 13 is fixedly connected below the first filter screen plate 8. When the driving mechanism drives the second filter screen plate 9 to move to the right, the second filter screen plate 9 drives the first filter screen plate 8 to horizontally slide to the right into the cleaning chamber 3. When the second filter screen plate 9 moves into the filtering chamber 2, the first filter screen plate 8 drives the plug 13 to be hermetically inserted into the through hole 14. Above the first filter screen plate 8 and on the right side of the cleaning chamber 3, a dirt discharge port 18 is penetrated and opened. The top plate of the transition tank 15 is a drainage plate 19 inclined downward from left to right. The drainage plate 19 is located below the dirt discharge port 18 and above the dirt accumulation tank 16. A drain port 17 penetrates through the rear side of the transition tank 15.

[0020] When the present utility model is in use, sewage enters from the upper end of the filtering chamber 2 and is initially filtered through the first filter screen plate 8. The filtered water enters the storage tank 1 and then enters the transition tank 15 through the through hole 14, and is discharged to a designated position through the pipeline connected to the drain port 17. After a period of time, when it is necessary to clean the dirt on the upper end of the first filter screen plate 8, the driving mechanism is started, thereby driving the first filter screen plate 8 and the second filter screen plate 9 to displace to the right. The second filter screen plate 9 replaces the original position of the first filter screen plate 8, while the first filter screen plate 8 displaces into the interior of the cleaning chamber 3, and the right end is inserted into the lower part of the side wall of the dirt discharge port 18. And the first filter screen plate 8 drives the plug 13 to displace to the right, thereby being inserted into the interior of the through hole 14 to seal the through hole 14. In this way, as the water level rises, the filtered water will overflow the first filter screen plate 8, so that the dirt discharge port 18 discharges to the interior of the dirt accumulation tank 16 through the drainage plate 19. In this way, the first filter screen plate 8 can be backflushed and decontaminated, so that the cleaning of the dirt on the upper end of the first filter screen plate 8 is more convenient, and it is not necessary to disassemble and clean the dirt on the upper end of the first filter screen plate 8. After the cleaning is completed, the driving mechanism will drive the first filter screen plate 8 and the second filter screen plate 9 to displace to the left for a certain distance first, so that the plug 13 displaces to the left, causing the water level inside the storage tank 1 to drop by a certain distance, and then continue to displace to the left and return to the initial position.

[0021] Specifically, two lifting plates 21 are fixedly connected to the first filter plate 8 and the second filter plate 9 respectively. The two lifting plates 21 are symmetrically arranged front and back. The lifting plate 21 is in the shape of a right triangle. Slots 20 are respectively opened on the front and rear sides of the bottom end of the baffle 4. The slots 20 are adapted to the acute angles of the lifting plates 21. When the first filter plate 8 moves to the right, the lifting plate 21 on the first filter plate 8 is inserted into the slot 20, so that the lifting plate 21 abuts against the baffle 4 and moves it upward. At the same time, the lifting plate 21 on the second filter plate 9 slides through the side wall of the filter chamber 2. During this process, the left end of the lifting plate 21 on the first filter plate 8 is always in the slot 20, so that the baffle 4 does not contact the first filter plate 8, thus preventing the baffle 4 from scraping the dirt on the upper end of the first filter plate 8 and accumulating at the left end of the baffle 4. At this time, the left end of the lifting plate 21 on the second filter plate 9 is sealingly connected to the inner side wall of the filter chamber 2.

[0022] Specifically, frames are fixedly connected to the four peripheries of the first filter plate 8 and the second filter plate 9. Plug slots are opened at the joints where the frames are inserted into the filter chamber 2 or the cleaning chamber 3. The frames are sealingly and slidably connected to the plug slots. A plurality of equally spaced brackets 7 are fixedly connected to the top wall of the cleaning chamber 3. A sliding rod 6 is slidably connected to the brackets 7 in the vertical direction. The bottom end of the sliding rod 6 is fixedly connected to the top of the baffle 4. A spring 5 is coaxially sleeved on the outer side of the sliding rod 6. The top end of the spring 5 is fixedly connected to the bracket 7, and the bottom end of the spring 5 is fixedly connected to the baffle 4. By setting the spring 5, the spring 5 is in a compressed state, which can make the lower end of the baffle 4 press the upper end of the frame of the first filter plate 8, increasing the sealing degree.

[0023] The driving mechanism of the present utility model includes an electric telescopic rod 10 fixedly installed on the side wall of the filter chamber 2. The telescopic end of the electric telescopic rod 10 is fixedly connected to the frame of the second filter plate 9. The second filter plate 9 is driven to move horizontally by the electric telescopic rod 10, so as to drive the first filter plate 8 to move horizontally. The lower side of the right side frame of the first filter plate 8 abuts against a support plate 11. The front and rear ends of the support plate 11 are respectively fixedly connected to the front and rear inner side walls of the cleaning chamber 3. The lower right end of the lower side of the right side frame of the first filter plate 8 is fixedly connected to a connecting plate 12. The right bottom end of the connecting plate 12 is fixedly connected to a plug 13. The plug 13 and the through hole 14 are coaxially arranged.

[0024] Working principle:

[0025] Sewage enters from the upper end of the filtration tank 2. After preliminary filtration by the first filter plate 8, the filtered water enters the storage tank 1 and then enters the transition tank 15 through the through hole 14, and is discharged to a designated location through the pipeline connected to the drain port 17. After a period of time, when it is necessary to clean the dirt on the upper end of the first filter plate 8, the electric telescopic rod 10 is started, which drives the first filter plate 8 and the second filter plate 9 to move to the right. The second filter plate 9 replaces the original position of the first filter plate 8, and the first filter plate 8 moves into the interior of the cleaning tank 3, and the right end is inserted into the lower part of the side wall of the dirt discharge port 18. And during the process of the lifting plate 21 being inserted into the slot 20 of the baffle plate 4, the lifting plate 21 will force the baffle plate 4 to move upward, so as to prevent the baffle plate 4 from scraping the dirt on the upper end of the first filter plate 8 and gathering at the left end of the baffle plate 4. And the plug 13 is driven to move to the right by the connecting plate 12, so as to be inserted into the interior of the through hole 14 to seal the through hole 14. In this way, as the water level rises, the filtered water will overflow the first filter plate 8, and then be discharged into the dirt gathering tank 16 through the dirt discharge port 18. In this way, the first filter plate 8 can be backflushed and decontaminated, making it more convenient to clean the dirt on the upper end of the first filter plate 8, and there is no need to disassemble and clean the dirt on the upper end of the first filter plate 8. After the cleaning is completed, the electric telescopic rod 10 will drive the first filter plate 8 and the second filter plate 9 to move to the left for a certain distance first, so that the plug 13 moves to the left, causing the water level in the storage tank 1 to drop by a certain distance, and then continue to move to the left and return to the initial position.
