[0002] A large amount of wastewater is generated during the processing of sand and gravel aggregates, which contains impurities such as suspended solids and fine sand. Generally, it will be collected and then treated centrally using a wastewater treatment device. Existing wastewater treatment devices generally use filter cartridges or filter meshes to intercept impurities to achieve the purpose of wastewater filtration and impurity separation, and it is also convenient for unified recovery and treatment of impurities in the later stage.

[0003] However, when the wastewater from sand and gravel aggregate processing passes through the filter cartridge, the impurities therein may get stuck or adsorbed on the surface of the filter cartridge, gradually accumulate and cause blockage, resulting in a reduction in filtration efficiency and greatly prolonging the treatment time of the wastewater from sand and gravel aggregate processing. At the same time, manual dredging of the filter cartridge is required during the unified recovery and treatment of impurities, increasing the labor intensity of the operators.

[0004] Therefore, a brand-new wastewater treatment device for sand and gravel aggregate processing is proposed to solve the above technical problems. Content of the Utility Model

After the output shaft vertically penetrates through the top wall of the treatment tank 1, it is connected to one end of a cross link 7, and the other end of the cross link 7 is connected to the top of a vertical first link 8;

[0028] A second link, which is horizontally arranged along the radial direction of the filter basket 3, and the bottom of the first link 8 is connected to the end of the second link 9 far from the drain pipe 4;

[0029] Cleaning brush hairs, which are arranged outside the first link 8 and the second link 9.

[0030] In the present utility model, after the wastewater from sand and gravel aggregate processing (hereinafter referred to as wastewater) is collected and converged by a wastewater collection device, it is introduced into the treatment tank 1 through the wastewater conveying pipe 2 and is located outside the filter basket 3. After the wastewater passes through the filter basket 3 for filtration, impurities such as suspended matters and fine sand (hereinafter referred to as impurities) are blocked by the filter holes of the filter basket 3. The filtered wastewater is discharged from the treatment tank 1 through the drain pipe 4 under the action of the water pump 5, completing the wastewater treatment process. During the filtration process, the output shaft of the driving motor 6 drives the cross link 7 to rotate around the output shaft, and then drives the first link 8 and the second link 9 to rotate around the vertical position where the output shaft is located, so as to use the cleaning brush hairs on the first link 8 and the second link 9 to clean the mesh holes of the filter basket 3, avoiding impurities getting stuck or adsorbed in the mesh holes of the filter basket 3, and achieving the purpose of preventing impurity accumulation from blocking the mesh holes of the filter basket 3.
