[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 A quartz sand filter for wastewater treatment shown in the figure comprises a tank body 1, a filling port 10 for adding quartz sand is arranged at the left position of the upper end of the tank body 1, the tank body 1 is moved by a lifting lug 11 fixed at the right position of the upper end, supporting feet 17 are installed at the four corners of the lower end of the tank body 1 to support it, an exhaust port 8 for exhaust is arranged at the upper position of the left end of the tank body 1, and a forward wash inlet 9, a backwash outlet 2, a forward wash outlet 3 and a backwash inlet are arranged at the four corners of the front end of the tank body 1. 4, the forward wash inlet 9 and the backwash inlet 4 are connected with a water inlet 6 at the left end position, a box body 7 is fixed at the inner side of the water inlet 6, a stainless steel mesh groove 12 is inserted into the box body 7 at the upper end position, the stainless steel mesh groove 12 is connected with the aperture at the inner side of the water inlet 6 through the water inlet hole 16 at the front end position, a rotatable rotating shaft 13 is sleeved at the inner side position of the box body 7, a plurality of fixed plates 14 are fixed at the outer wall position of the rotating shaft 13, and a brush 15 is arranged at the outer end surface position of the fixed plate 14.

[0024] The quartz sand filter introduces wastewater through the water inlet 6, and the wastewater enters the quartz sand packing layer through the packing port 10. The packing port 10 is used to add quartz sand. While the clean water flow is injected into the forward wash inlet 9, the quartz sand removes suspended matter and particulate matter in the water. The exhaust port 8 is used to discharge the generated gas. The backwash inlet 4 injects backwash water flow to wash the impurities accumulated on the surface of the quartz sand; the cleaned wastewater and the washed impurities are discharged through the forward wash outlet 3 and the backwash outlet 2. Finally, the quartz sand packing is regularly cleaned and replaced through the discharge port 5 to ensure that the quartz sand filter can effectively remove impurities in the wastewater and achieve the purpose of water purification.

[0025] like Figure 1 and Figure 3 As shown, the filling port 10 adds quartz sand into the inner position of the tank body 1, and the tank body 1 filters out impurities such as particulate matter and organic matter in the wastewater through the quartz sand. The discharge port 5 cleans the used quartz sand. After the discharge port 5 is cleaned, new quartz sand is replaced through the filling port 10, and the forward wash inlet 9 injects clean water to wash away the impurities adsorbed on the surface of the quartz sand. The backwash inlet 4 reversely washes the quartz sand filling layer. The fixed plate 14 will move when it contacts the wastewater. The movement of the fixed plate 14 causes the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 causes the brush 15 to contact the inner wall position of the stainless steel mesh groove 12.

[0026] When wastewater enters the inner position of the stainless steel mesh groove 12, the fixed plate 14 will move, and the movement of the fixed plate 14 will cause the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 causes the brush 15 to contact the inner wall of the stainless steel mesh groove 12, so that impurities adsorbed on the inner wall of the stainless steel mesh groove 12 can be cleaned up to prevent the impurities from affecting the normal flow of wastewater.

[0027] like Figure 2 and Figure 3 As shown, the forward wash outlet 3 and the backwash outlet 2 discharge the cleaned waste water and the flushed impurities respectively, and the water inlet 6 transports the waste water to the internal position of the tank body 1 for filtration. The water inlet 6 passes through the box body 7 and the stainless steel mesh groove 12 when transporting the waste water. The stainless steel mesh groove 12 transports the waste water to the internal position through the water inlet hole 16 at the front end position, and the stainless steel mesh groove 12 isolates large impurities.

[0028] A stainless steel mesh groove 12 is inserted into the inner side of the box body 7. The stainless steel mesh groove 12 allows large impurities and wastewater to flow to the inner position of the mesh groove through the water inlet hole 16 at the front end. When the flow continues, the stainless steel mesh groove 12 isolates the large impurities so that the wastewater continues to flow. In this way, the large impurities will not flow to the inner position of the tank body 1, so that the quartz sand inside the tank body 1 can maintain a good filtering effect. After use, the stainless steel mesh groove 12 can be moved up and taken out from the inner position of the box body 7, and the impurities inside the stainless steel mesh groove 12 can be cleaned.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
