Technical Field

The utility model relates to the technical field of chemical equipment, in particular to a filtering device for chemical industry.

Background technique

In the chemical industry, many reactions are carried out in reactors, and the products after the reactions need to be treated, so a large amount of wastewater is generated. These wastewaters often contain lumps or particles of different sizes. In order to make the generated wastewater meet the standards, filtering devices are often used for treatment. After long-term use, the existing filtering devices will cause the filter to be blocked by impurities, resulting in reduced filtering efficiency. At this time, the machine needs to be shut down for cleaning. If the machine is shut down, the overall production efficiency will be affected. In addition, the existing filtering devices cannot judge the blockage of the filter. The filter is often cleaned only when the filtering efficiency drops significantly. The work is relatively passive, which is not conducive to ensuring the service life of the filter.
