Technical Field

[0001] The invention relates to the technical field of industrial filter screen cleaning, and in particular to an industrial filter screen self-cleaning device. Background Art

[0002] As an indispensable key component in the industrial production process, industrial filters play an important role in filtering media, separating impurities, and protecting equipment. They are widely used in many fields such as chemical industry, pharmaceutical industry, food processing, water treatment, paint spraying, and air purification. Through precise aperture design and diversified material selection, they can effectively intercept pollutants such as suspended particles, grease, and microorganisms to ensure smooth production processes and stable product quality.

[0003] The performance of industrial filters is directly related to production efficiency and product purity. For industrial filters, a large amount of dust and industrial impurities often accumulate during the filtering process. Therefore, how to clean the industrial filters and make the cleaning more efficient becomes more important. For this reason, the prior art (Announcement No. CN209379566U) discloses an industrial filter circulation cleaning device, which not only realizes the detachable installation function, improves the convenience of the overall device, but also improves the practicality of the overall device, while achieving the effect of circulation cleaning, which is also conducive to saving water and reducing costs.

[0004] However, the above-mentioned existing industrial filter circulation cleaning device still has the following technical problems during use: since the industrial filter is connected by buckles, it is troublesome to load and unload materials, and the degree of automation is not high. In addition, the cleaning position of the industrial filter is relatively single, which is not enough to clean multiple industrial filters at the same time. Summary of the invention
