DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a silicon slag wastewater treatment device, comprising a filter pipe section 1, both ends of the filter pipe section 1 are connected to a connecting pipe section 2, a dirt collecting box 4 is connected to the bottom of the filter pipe section 1, a filter plate 3 is fixedly installed between the dirt collecting box 4 and the inner wall of the filter pipe section 1 at a position close to the connecting pipe section 2 at one end, one end of a bracket 6 is fixedly connected to the inner wall of the filter pipe section 1, and a self-rotating cleaning mechanism 5 is rotatably installed on the other end of the bracket 6, and the self-rotating cleaning mechanism 5 is located on one side of the filter plate 3.

[0022] See also Figures 2 to 4 The self-rotating cleaning mechanism 5 includes a rotating shaft 501, which is rotatably connected to one end of the bracket 6. An impeller 502 is fixedly sleeved on the rotating shaft 501. A plurality of mounting plates 503 evenly distributed in an annular shape are fixedly mounted on the outer wall of the circumference of one end of the rotating shaft 501 close to the filter plate 3. A brush 504 is arranged on the surface of each mounting plate 503 on one side facing the filter plate 3, and each brush 504 is in contact with the filter screen part of the filter plate 3.

[0023] When the device is connected to the sewage pipe as a whole, the sewage enters the filter pipe section 1 from the connecting pipe section 2 at one end. When the water flows through the impeller 502 and drives the rotating shaft 501 to rotate, several mounting plates 503 at one end of the rotating shaft 501 will also rotate accordingly, so that the brush 504 provided on the surface of one side of the mounting plate 503 will brush the filter screen part of the filter plate 3 and brush off foreign matter adhering to the filter screen, thereby ensuring the filtering effect of the filter plate 3 on the sewage.

[0024] Furthermore, a guide cone 505 is fixedly mounted on the other end of the rotating shaft 501 .

[0025] The flow guide cone 505 can reduce the resistance of the water flow, thereby ensuring the rotation efficiency of the impeller 502 and improving the cleaning efficiency of the brush 504 on the filter plate 3.

[0026] Furthermore, each mounting plate 503 has an inclination angle relative to the rotating shaft 501 , and the inclination direction is consistent with the direction of the blades of the impeller 502 .

[0027] The mounting plate 503 has a certain inclination angle relative to the rotating shaft 501 in the Y-axis direction, and the inclination direction is kept consistent with the blade direction of the impeller 502, which can further reduce water flow resistance and reduce the impact on the sewage flow rate, thereby ensuring the efficiency of sewage filtration treatment.

[0028] See also Figures 1 to 3 An internal thread 201 is provided on the inner wall of each connecting pipe section 2.

[0029] By providing an internal thread 201 on the inner wall of the connecting pipe section 2, the device can be more conveniently connected to the sewage pipeline as a whole, and it is also convenient for later disassembly and replacement, providing convenience for installation and disassembly.

[0030] Furthermore, the inner wall of the bottom of the dirt collecting box 4 is a gradually deepening structure, and the depth of one end close to the filter plate 3 is greater than that of the other end.

[0031] When the silicon slag and other foreign matter in the sewage is blocked by the filter plate 3, it will sink along the filter plate 3 to the deeper side of the sewage collecting box 4 for collection and storage. When the silicon slag and other foreign matter in the sewage is blocked by the filter plate 3, it will sink along the filter plate 3 to the deeper side of the sewage collecting box 4 for collection and storage.

[0032] Further, the bottom inner wall inclined surface of the dirt collecting box 4 is provided with a through slag discharge port 401, and a flap 402 is rotatably mounted on one side edge of the slag discharge port 401 through a hinge, and a door lock mechanism is provided on the flap 402. The bottom inner wall inclined surface of the dirt collecting box 4 is provided with a through slag discharge port 401, and a flap 402 is rotatably mounted on one side edge of the slag discharge port 401 through a hinge, and a door lock mechanism is provided on the flap 402.

[0033] During the filtration of sewage, the flap 402 is closed to seal the filter pipe section 1 and the sewage collecting box 4 as a whole, thereby ensuring the filtration effect of the sewage. When the treatment is completed, the flap 402 can be opened to remove and collect other foreign matter such as silicon slag in the sewage collecting box 4.

[0034] Furthermore, an isolation plate 7 is fixedly mounted on the inner wall of one end of the dirt collecting box 4 , and one end of the bracket 6 away from the self-rotating cleaning mechanism 5 is fixedly connected to the upper surface of the isolation plate 7 .

[0035] By providing the isolation plate 7 inside the slag discharge port 401, it is possible to reduce the possibility that the filtered silicon slag is deposited at the bottom of the slag collecting box 4 and is affected by the water flow and floats in the slag collecting box 4, thereby affecting the rotation efficiency of the impeller 502. It is also possible to reduce the possibility that the impeller 502 breaks up the silicon slag during rotation, thereby allowing smaller particles to pass through the filter plate 3 and reduce the filtering effect.

[0036] Working principle: The device is connected to the sewage pipe as a whole through the internal threads 201 arranged on the inner walls of the connecting pipe sections 2 at both ends. When the sewage containing silicon slag enters the filter pipe section 1, the water flow through the impeller 502 will drive the rotating shaft 501 to rotate. When the rotating shaft 501 rotates, it will also drive all the mounting plates 503 to rotate, so that the filter screen part of the filter plate 3 is brushed by the brush 504 arranged on the surface of one side of the mounting plate 503, and the silicon slag and other foreign matter adhering to the filter screen are brushed off to avoid clogging of the filter screen and affecting the filtration efficiency. The filtered silicon slag and other foreign matter will be deposited in the deeper part of the sewage collecting box 4 for collection and storage. When the filtration process is completed, the flap 402 can be opened to discharge the filtered silicon slag and other foreign matter from the slag discharge port 401 for collection. The collected silicon slag can be reused for refining, thereby avoiding waste of raw materials and saving processing costs.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
