Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, and particularly relates to a sewage treatment device for vehicle production and manufacturing. BACKGROUND

[0002] In the vehicle production and manufacturing process, a large amount of industrial wastewater containing oil stains, metal scraps and paint residues is generated in the processes such as welding, painting and part cleaning. If the wastewater is directly discharged without effective treatment, the soil and water body will be seriously polluted, which violates the environmental protection regulations. At the same time, incomplete wastewater treatment will also affect the recycling efficiency of water resources and increase the production cost of enterprises. Therefore, the sewage treatment device for vehicle production and manufacturing is a key equipment to ensure that enterprises meet environmental protection standards and reduce operating costs, and the smoothness of the sludge discharge of the device directly determines the continuous stability of the sewage treatment.

[0003] At present, the sewage treatment device for vehicle production and manufacturing on the market has obvious defects. The sludge discharge hopper of the existing device is mostly a single funnel structure, and lacks targeted cleaning and dredging design. After the oil stains and metal scraps contained in the vehicle production wastewater are mixed, the viscous sludge deposits are easily formed on the inner wall of the sludge discharge hopper. Long-term accumulation not only reduces the sludge discharge channel, but also makes it difficult for the sludge to naturally fall off due to strong adhesion, resulting in a continuous decrease in sludge discharge efficiency. More seriously, the sludge deposits are easily accumulated and agglomerated at the outlet of the sludge discharge hopper, causing outlet blockage. At this time, manual cleaning is required, which not only interrupts the sewage treatment process, but also increases the labor intensity of the operation and maintenance personnel. In addition, manual cleaning has the problem of incomplete cleaning, and the residual sludge will accelerate subsequent blockage, forming a vicious cycle of "blockage-cleaning-reblocking". Although some devices try to alleviate the blockage by increasing the diameter of the outlet, they still cannot solve the problem of sludge adhesion on the inner wall, and the large-diameter outlet will cause clean water to be discharged together with the sludge, reducing the sludge-water separation effect and affecting the water quality. Therefore, it is urgent to improve. SUMMARY
