Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a long-acting chemical filtering unit. Background Art

[0002] After the preparation of chemicals, they need to be filtered because certain impurities may be introduced into the chemicals during the production, transportation or storage process. The presence of solid impurities may affect the purity of the chemicals, and thus affect their performance and use. Therefore, through filtration, the purity of the chemicals can be ensured to meet specific application requirements;

[0003] Since the main function of the filter is to filter impurities in chemicals, during use, a large amount of pollutants, such as dust, particulate matter, etc., will be intercepted on the outer surface of the filter element, and over time, these pollutants will gradually accumulate to form a visible impurity layer. The existence of the impurity layer will directly affect the filtering effect. It will block the pore size of the filter element, causing some liquid to pass through without being fully filtered, resulting in a decrease in the purity of the filtered chemicals. The accumulation of the impurity layer will also increase the workload of the filter element and accelerate its aging process, thereby shortening the service life of the filter element. Due to the installation method of the existing filter element, it is necessary to open the end cover of the filter and then remove the filter element from the filter for cleaning. Therefore, the above-mentioned filter element cleaning method is very inconvenient to operate, and it is impossible to achieve regular and efficient cleaning of the filter element.
