Technical Field

[0001] The utility model relates to the field of sodium hypophosphite production equipment, and particularly to a filtering liquid collecting structure for sodium hypophosphite production. Background Technique

[0002] During the production process of sodium hypophosphite, the collection of the filtering liquid is a key step, which usually depends on a plate and frame filter press to complete. The liquid collection tanks on both sides of the plate and frame filter press are important components of the filtering liquid collection mechanism. These collection tanks are designed to closely cooperate with the plate and frame filter press to ensure that the filtering liquid discharged from the filter press can smoothly flow into the tanks for subsequent collection and treatment.

[0003] In the existing filtering liquid collecting structure for sodium hypophosphite production, during long-term use, in order not to affect the liquid discharge efficiency of the collection tank by the plate and frame filter press, an open design is usually adopted. However, this open setting has certain defects. Since the collection tank is in an open state, it is more vulnerable to the influence of the external environment, such as the intrusion of pollutants such as dust and impurities. These pollutants may mix into the filtering liquid, affecting its quality and purity, and thus having an adverse impact on the production process of sodium hypophosphite. Content of the Utility Model
