Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment and relates to a filter element cleaning device. Background Art

[0002] The chemical industry is a national basic industry and also a high water-consuming industry. Relevant data show that the water consumption of my country's chemical enterprises reaches 12 billion cubic meters per year, and desalted water, as an important production medium, is widely used in industrial production.

[0003] At present, tracked desalted water filters are widely used. For example, CN205103583U records a tracked desalted water filter, which filters the desalted water through non-woven fabric to be reused after filtering. However, the non-woven fabric becomes dirty after filtering and cannot be used any more, resulting in a situation that is difficult to handle and easy to waste.

[0004] The automatic melt filter element cleaning machine is easy to flush, but the mechanical part (transmission thread) needs to be greased when it is in operation. The grease applied will contaminate the filter element after high-pressure water flushing, and the generated desalted water will be contaminated by oil and cannot be recycled. If it is not greased, it will be worn out for a long time and metal chips will fall off, contaminating the cleaned filter element and thus the product.

[0005] Therefore, it is of great significance to study a filter element cleaning device to solve the problems of difficulty in recycling and reusing desalted water and serious waste of resources in the prior art. Utility Model Content
