Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a filter for producing chemical raw material medicines. Background Art

[0002] In the production process of chemical APIs, filters are one of the indispensable equipment. Their main function is to remove impurities from raw materials or products to ensure product quality. However, as production continues, fixed particles and other dirt will gradually accumulate on the filter element, which will not only affect the filtering effect, but may also cause the filter element to be blocked, thereby affecting production efficiency and increasing maintenance costs.

[0003] Traditional filter designs usually require manual cleaning or replacement when the filter element is clogged or seriously contaminated, which is not only time-consuming and labor-intensive, but may also lead to loss of raw materials and environmental pollution during the cleaning process. In addition, manual cleaning is difficult to completely remove fixed particles and tiny dirt on the filter element, which may pose a potential threat to product quality if accumulated over a long period of time.

[0004] In order to solve the above problems, some filters with self-cleaning functions have appeared on the market in recent years. These filters are usually equipped with self-cleaning mechanisms such as high-pressure water guns, gas backwash devices or ultrasonic cleaning devices, which can automatically clean the dirt on the surface of the filter element without manual intervention. However, the existing self-cleaning filters still have some shortcomings, such as unstable cleaning effect, high energy consumption, and high maintenance costs.

[0005] Therefore, it is necessary to develop a filter for the production of chemical raw materials to overcome the shortcomings of the prior art. Utility Model Content
