Description

Technical Field

[0001] The utility model relates to the field of sodium hypophosphite production equipment, in particular to a crystallization and drying device for sodium hypophosphite production. Background Technique

[0002] The crystallization and drying device for sodium hypophosphite production is an efficient and professional device. It mainly uses a hollow spiral vacuum dryer to dry sodium hypophosphite crystals. This device reduces the drying temperature of the material through a vacuum environment, avoiding the decomposition or deterioration of sodium hypophosphite at high temperatures. At the same time, the hollow spiral structure can increase the contact area between the material and hot air, improve the drying efficiency, and ensure the drying quality and production efficiency of sodium hypophosphite crystals.

[0003] Since the existing crystallization and drying devices for sodium hypophosphite production have some problems during the drying process when processing sodium hypophosphite, such as uneven distribution of the material on the spiral conveyor belt, which may lead to inconsistent drying effects. Although the hollow spiral structure of the device helps to a certain extent in the mixing and turning of the material, enabling the material to come into more sufficient contact with hot air, when dealing with high-viscosity or easily caking materials, this structure may seem inadequate. Moreover, high-viscosity materials are prone to adhering to the conveyor belt or the inner wall of the device, forming stubborn residues. This not only hinders the achievement of the drying effect, resulting in low processing efficiency, but also may increase the difficulty of cleaning and maintenance, leading to an increase in production costs. Therefore, it is urgent to develop a new type of crystallization and drying device for sodium hypophosphite production. Content of the Utility Model

At the same time, through the observation port, operators can timely discover abnormal situations during the drying process, such as material accumulation, uneven drying or equipment failure, and can handle them in a timely manner, effectively avoiding the occurrence of safety accidents. In addition, the observation port enables operators to more accurately judge the completion degree of the drying process, thereby more precisely controlling the drying time and improving the production efficiency. Compared with frequently opening the inspection cover for inspection, the design of the observation port reduces the interference of external factors on the drying process and helps to maintain the stability of the drying environment. The combination of the inspection cover and the observation port further improves the convenience and practicality of the equipment. The design of the inspection cover facilitates the regular maintenance and inspection of the inside of the drying equipment, and the setting of the observation port makes this process more efficient because operators can first judge whether it is necessary to open the inspection cover for further operations through the observation port.
