Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a filtering device for wastewater treatment. Background Art

[0002] Wastewater refers to water that has been used and cannot be used again, such as water for washing face, washing vegetables, washing clothes, flushing toilets, washing wounds, toxic water and industrial wastewater. In order to reduce the adverse effects of wastewater on water resources, it is necessary to filter the wastewater before formulating it. The wastewater filtration process refers to the process of separating or decomposing various pollutants contained in the wastewater from the water to purify the wastewater.

[0003] At present, wastewater is filtered and treated using a wastewater treatment filter device, which refers to a filtering facility that removes suspended matter from wastewater. The structural components of the wastewater filter device include: a filter barrel, a filter screen, a water inlet pipe, a drain pipe, a sewage pipe, a sewage valve, a motor, a connecting shaft, and a steel brush.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing wastewater treatment and filtering device, during use, the wastewater inside the filter barrel is filtered through the filter net, and the filtered water is discharged through the drain pipe, and the motor drives the connecting shaft to rotate, and the rotating connecting shaft drives the steel brush to clean the waste residue on the filter net, and then the slag discharge valve is opened to discharge the waste residue through the slag discharge pipe. However, it is not convenient to filter the wastewater while discharging the waste residue at the filter in time, which will cause excessive accumulation of waste residue and even block the drain pipe, affecting the filtration efficiency of the wastewater and not conducive to the discharge of water;

[0006] 2. In the existing wastewater treatment and filtering device, waste residue is discharged by opening the slag discharge valve on the slag discharge pipe during use. However, waste residue will remain in the slag discharge pipe during use. As too much waste residue remains in the slag discharge pipe, the waste residue discharge efficiency will be reduced, and even the slag discharge pipe will be blocked.

[0007] To this end, we provide a filtering device for wastewater treatment to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a filtering device for wastewater treatment, which solves the problem that the existing wastewater treatment filtering device is not convenient for timely discharge of waste residues and is not convenient for clearing the residue discharge pipe by arranging a residue discharge component and a blockage clearing component.

[0009] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0010] The utility model relates to a filtering device for wastewater treatment, which comprises a filtering barrel.
