Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices for purifying waste emulsion, in particular to a filtering mechanism for purifying waste emulsion. Background Art

[0002] As we all know, in industrial production, especially in metal processing, machinery manufacturing and other industries, waste emulsion is a common industrial wastewater, and its purification treatment is particularly important. Waste emulsion usually contains oil, metal debris, chemical additives and other pollutants. If it is discharged directly without treatment, it will not only cause serious environmental pollution, but also may violate environmental protection regulations and damage the reputation and economy of the company. The traditional waste emulsion purification technology, especially the filtration link, the design of a single filter tank means that the filtration operation must be stopped when cleaning the filter layer, resulting in an intermittent decrease in processing capacity and affecting production efficiency. The filter layer is easily blocked by fine particles. Frequent blockage will reduce the filtration speed, increase energy consumption and processing costs. The cleaning of the filter layer usually requires manual operation, disassembly, cleaning and reassembly. This process is time-consuming and laborious, and may damage the equipment due to improper operation. The lack of an effective automated cleaning system causes the equipment operation to rely on manual monitoring and operation, making it difficult to achieve 24-hour uninterrupted and efficient operation. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content
