[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 The filtration system of the present invention is simple, and the filtration system of the present invention is simple and convenient to use.

[0022] The large particles of impurities and construction waste contained in the construction wastewater are isolated by the filter plate 5, and the interior of the device body 1 is divided into a first chamber 3 and a second chamber 4 by the partition 2, so that the filtered construction wastewater is gradually gathered in the first chamber 3, and the sediment in the water is precipitated to form a stratification phenomenon. The wastewater containing a small amount of sediment in the upper part flows from the top of the partition 2 to the second chamber 4, and is precipitated again, further reducing the sediment content in the wastewater, thereby greatly improving the wastewater recycling rate. The electric telescopic rod 6 drives the telescopic shaft to drive the push plate 7 to move, so that the scraper 8 pushes the large particles of impurities and construction waste isolated on the filter plate 5, thereby achieving the cleaning effect of the filter plate 5, and the cleaned debris is discharged from the inside of the device body 1 through the slot 11. Compared with the existing technology, the operation is simple and convenient, labor costs are saved, and cleaning efficiency is improved.

[0023] Specifically, in this embodiment, the push plate 7 and the scraper 8 are hinged to each other by a hinge 12, and the hinge 12 is arranged on the same side of the push plate 7 and the scraper 8 close to the notch 11. The connection of the hinge 12 enables the scraper 8 to follow the push plate 7 to move toward the notch 11. The rotation of the hinge 12 is affected by the contact surface between the push plate 7 and the scraper 8 and is restricted. The scraper 8 and the push plate 7 form a whole, which facilitates pushing the debris on the filter plate 5 toward the notch 11. When the scraper 8 follows the push plate 7 to move away from the notch 11, the scraper 8 can rotate under the effect of being blocked by debris on the filter plate 5, thereby preventing the push plate 7 from pushing the debris back when driving the scraper 8 to retract, and ensuring that the debris is always pushed in the direction of the notch 11.

[0024] Specifically, in this embodiment, a baffle 13 is connected to the filter plate 5, the top of the baffle 13 is connected to the top of the inner wall of the device body 1, and the two ends are connected to the inner walls at both ends of the device body 1, so as to prevent debris on the filter plate 5 and construction wastewater that has not been filtered in time from entering the second chamber 4.

[0025] Specifically, in this embodiment, the height of the water inlet pipe 9 is higher than the top height of the partition 2, and the height of the water outlet pipe 10 is lower than the top height of the partition 2 to prevent backflow.

[0026] Specifically, in this embodiment, a first sewage pipe 14 is connected to one side of the device body 1, and the first sewage pipe 14 is connected to the bottom end of the first chamber 3. A first valve 15 is provided on the first sewage pipe 14. When the first valve 15 is closed, it ensures the convergence of water flow in the first chamber 3, and when it is opened, it facilitates the cleaning of accumulated mud and sand in the first chamber 3.

[0027] Specifically, in this embodiment, a second sewage pipe 16 is connected to the other side of the device body 1, and the second sewage pipe 16 is connected to the bottom end of the second chamber 4. A second valve 17 is provided on the second sewage pipe 16. When the second valve 17 is closed, it ensures the convergence of water flow in the second chamber 4, and when it is opened, it facilitates the cleaning of accumulated mud and sand in the second chamber 4.

[0028] Specifically, in this embodiment, the bottom end of the notch 11 is inclined from the inside to the outside of the device body 1 and from bottom to top, ensuring that debris can be discharged smoothly while preventing unfiltered wastewater from seeping out from the bottom of the notch 11.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
