Description

Technical Field

[0001] This utility model relates to the field of water glass preparation technology, specifically to a high-efficiency filtration device for water glass production. Background Technology

[0002] Filtration of water glass solution is one of the important steps in the preparation of water glass. The filtration step is performed after the reaction is completed, that is, after the mixing and reaction steps and before the concentration and evaporation steps. The contents passed into the filtration device are the mixture obtained after the reaction, which contains water glass liquid, solid impurities, and unreacted raw materials.

[0003] With increasing environmental awareness and higher industrial production requirements, the demands on the quality of water glass and its filtration technology are becoming increasingly stringent. The principle of water glass solution filtration devices is mainly to utilize physical filtration and separation technology to separate impurities and particles from the liquid, thereby purifying the water and improving the quality of the water glass.

[0004] Because water glass solutions contain not only a large number of solid impurities and unreacted raw materials, but also small solid particles and flocs that precipitate and aggregate after the addition of impurity removal agents, a large amount of residue remains in the filtration device. Due to the large amount of residue, large filtration devices such as filter presses are required for filtration. However, large filtration devices are too expensive for small-scale water glass production, while small filtration devices are prone to clogging and difficult to clean. To address these issues, this invention provides a high-efficiency filtration device for water glass production. Utility Model Content
