Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a solution filtering device for chemical processing. Background Art

[0002] Generally speaking, chemical engineering is an abbreviation for "chemical process," "chemical industry," or "chemical engineering." Any technology that uses chemical methods to change the composition or structure of a substance or synthesize new substances is considered a chemical production technology, or chemical process. The resulting products are called chemicals or chemical products. Initially, these products were produced in workshops, which later evolved into factories and gradually formed a specific production industry: the chemical industry. Chemical engineering is the science that studies the common laws governing the production of chemical products. Humanity has a close relationship with the chemical industry. Some chemical products have played epoch-making roles in human history, and their production and application even represent specific historical stages of human civilization.

[0003] In the existing chemical processing process, it is usually necessary to filter the solution during processing to obtain a pure solution. However, there are many problems with the existing solution filtering device. First, due to the position limitation of the liquid injection port, the chemical solution can only fall toward the fixed position of the filter screen, which will cause the filter screen to be pressurized unbalanced over time. Second, after filtering different solutions, the inside of the filter device needs to be cleaned to avoid solution mixing and affecting the purity. However, the existing filtering device is inconvenient to clean. Therefore, a solution filtering device for chemical processing is provided to solve the above problems. Utility Model Content
