Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a chemical production precision filter. Background Art

[0002] Chemical production refers to the production process of using chemical methods to change the composition and structure of substances or synthesize new substances. In this process, the raw materials will undergo a series of physical and chemical processing steps to obtain valuable chemicals or chemical products. The core of chemical production is the chemical reaction process, which usually involves the pretreatment of raw materials, chemical reactions, and post-processing of products. The final products may include plastics, fertilizers, pesticides, coatings, paints, pharmaceutical intermediates, etc. These products are widely used in various fields of the national economy and people's lives. Precision filters are needed in chemical production. For example, a precision filter for chemical production and processing and a processing method thereof with publication number CN117398744A, which relates to the technical field of sodium benzoate preparation, includes a fixed base, a separator and a cleaning assembly, a shell is welded on the top of the fixed base, and a visual window is provided on the outer surface of the shell, and a water inlet pipe is connected through the left side of the shell. The precision filter for chemical production and processing and the processing method thereof are characterized in that the prepared liquid enters the outer shell through the water inlet pipe, first passes through the outer filter shell for the first filtration, and the prepared liquid entering the outer filter shell passes through the inner filter tube for the second filtration. In addition, by moving the top cover upward, the pull rod and the limit cover can be driven to move upward, so that the plug is pulled out of the plug hole, and the inner filter tube is pulled upward to separate the connecting seat from the through pipe. The improved precision filter achieves the purpose of double filtration through the coordinated use of the outer filter shell and the inner filter tube, improves the filtration effect, simplifies the disassembly and assembly process of the inner filter tube, and facilitates the regular replacement of the inner filter tube. In order to avoid the clogging of the outer filter shell and the inner filter tube and affect the normal use of the filter, they need to be cleaned, and the outer filter shell and the inner filter tube are cleaned by a magnetic suction ring and a metal ring. However, when cleaning the outer filter shell, only the inner side is cleaned, and the outer side cannot be cleaned, which still affects the normal use of the filter. Utility Model Content
