[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-5 As shown, a water filtering device for wastewater treatment includes a main pipeline and a control panel, and a filtering mechanism is arranged in the main pipeline;

[0027] The main pipeline is composed of two vertical pipes 1 and an inclined pipe 11. The two vertical pipes 1 are connected to the openings at both ends of the inclined pipe 11 respectively. A plurality of bypass pipes 12 are equidistantly arranged at the lower side of the inclined pipe 11. The number of the filtering mechanisms matches the number of the bypass pipes 12 and is located at the rear side of the bypass pipes 12.

[0028] The filtering mechanism includes a filtering plate 2, a cleaning component and a slag removal component. The filtering plate 2 is sealed and connected to the main pipeline. The cleaning component and the slag storage component are respectively arranged at the upper and lower ends of the filtering plate 2. The main pipeline is provided with a driver that matches the transmission of the filtering mechanism.

[0029] When treating sewage, the sewage is injected into the main pipeline through an external pumping device, wherein the inclined pipe 11 in the main pipeline is inclined to guide the sewage to flow downward and pass through the filtering mechanism, and the particle sizes of the filtered impurities of the plurality of filtering mechanisms can be the same or can be gradually reduced in the direction of the water flow;

[0030] When the sewage passes through the filter mechanism under the guidance of the inclined tube 11, impurities that do not meet the particle size of the filter plate 2 will be intercepted, and the sewage passes through the filter mechanism until it is finally discharged. As the filtering time and the amount of sewage treated increase, too many large particles of impurities will remain on the surface of the filter plate 2, thereby reducing the filtering efficiency of the filter plate 2 and affecting the overall sewage treatment efficiency. At this time, the filter plate 2 can be cleaned by manually operating the control panel or by controlling the cleaning component and the slag removal component through the start time preset by the control panel;

[0031] When cleaning the filter plate 2, the driver will start and drive the cleaning component and the slag removal component to start. At this time, the cleaning component scrapes the surface of the filter plate 2, and the slag removal component knocks the lower end of the filter plate 2 so that the impurities attached to the surface of the filter plate 2 are shaken off. With the help of clean water delivered from the outside, the impurities on the surface of the filter plate 2 are flushed into the adjacent bypass pipe 12 until they are discharged to the outside. In this way, the filter plate 2 can be effectively cleaned to avoid blockage that affects the filtration efficiency of sewage.

[0032] The driver includes a motor 3 and a main shaft 31. The motor 3 is fixedly arranged at one end of the main pipe relative to the drainage side. The main shaft 31 is rotatably sealed and arranged in the main pipe and is transmission-connected to the motor 3. The main shaft 31 matches the axis of the main pipe. The cleaning component and the slag removal component are both connected and matched with the main shaft 31.

[0033] The cleaning assembly includes a connecting rod 4 and a cleaning brush 41 . The connecting rod 4 is fixedly connected to the main shaft 31 and is perpendicular to the axis of the main shaft 31 . The cleaning brush 41 is connected to the lower end of the connecting rod 4 and matches the upper end of the filter plate 2 .

[0034] The slag removal assembly includes a striking rod 5, a guide plate 51 and an elastic member. The elastic member is embedded in the main shaft 31. There are several guide plates 51 evenly arranged at the lower end of the filter plate 2. The striking rod 5 is connected to the elastic member and matched with the guide plate 51.

[0035] The guide plate 51 is an inclined plate and its inclination direction matches the rotation direction of the main shaft 31 .

[0036] The elastic member includes a guide rod 6 and a spring 61. The main shaft 31 is provided with an installation cavity, which is composed of an inner cavity 62 and a movable groove 63 which are connected as one. The spring 61 is arranged in the inner cavity 62. The guide rod 6 is slidably arranged between the inner cavity 62 and the movable groove 63 and is connected to the spring 61. The striking rod 5 is connected to the other end of the guide rod 6.

[0037] When cleaning the filter plate 2, the motor 3 starts and drives the main shaft 31 to rotate. At this time, the main shaft 31 drives the cleaning component and the slag removal component to move to clean the filter plate 2. Specifically, the connecting rod 4 of the cleaning component directly follows the main shaft 31, and uses the cleaning brush 41 to brush the upper surface of the filter plate 2, so that most of the impurities on the upper end are brushed off. Furthermore, the striking rod 5 in the slag removal component follows the main shaft 31 through the elastic member, and the striking rod 5 is guided by the guide plate 51 to gradually move away from the corresponding filter plate 2 during the rotation, until the striking rod 5 completely crosses the guide plate 51. At this time, the spring 61 pushes the guide rod 6 to reset, that is, the striking rod 5 is instantly close to the filter plate 2, thereby producing an impact effect, which can vibrate and impact the filter plate 2, so as to force the overly stubborn impurities on the surface of the filter plate 2 to loosen, and can be cleaned with the cleaning brush 41.

[0038] A bellows cover 64 is provided between the upper and lower inner walls of the movable groove 63 and the striking rod 5 ; the bellows cover 64 can seal the opening of the movable groove 63 to prevent sewage and impurities from entering the movable groove 63 and affecting the operation of the components.

[0039] The bypass pipe 12 and the vertical pipe 1 at the drainage end are both provided with valves. The inclined pipe 11 is also provided with an arc-shaped air pipe 7 matching the filter plate 2 . The arc-shaped air pipe 7 is connected to the external air supply mechanism and is provided with a plurality of one-way air nozzles toward the bypass pipe 12 .

[0040] The setting of the valve can close the bypass pipe 12 when filtering sewage, so that the sewage flows to the vertical pipe 1 on the lower side. When cleaning the filter plate 2, the valve of the vertical pipe 1 at the drainage end is closed so that the clean water can be retained in the inclined pipe 11, ensuring that the water can guide the impurities remaining on the surface of the filter plate 2 to the bypass pipe 12. Furthermore, during the cleaning process, air can be input through an external air supply mechanism and output through a one-way air nozzle set on the arc-shaped air pipe 7. Since several one-way air nozzles are facing the bypass pipe 12, loose impurities and impurities floating in the water can be more effectively guided into the bypass pipe 12. Of course, the flow rate can also be controlled by controlling the opening size of the valve in the bypass pipe 12, so as to achieve more effective guidance and discharge of impurities.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
