Description

Technical Field

[0001] This utility model belongs to the technical field of red phosphorus production equipment, and in particular relates to a material transfer device in the production process of converting yellow phosphorus into red phosphorus. Background Technology

[0002] Currently, converting yellow phosphorus into red phosphorus is a common production process. The specific process flow is as follows: yellow phosphorus → melting in a pot → high-temperature conversion → ball milling → alkaline boiling → washing → centrifugal dehydration → vacuum drying → packaging and warehousing. The conversion principle is that the loaded yellow phosphorus is heated to a temperature of about 295℃-300℃ for a long time in the absence of air, which can convert it into red phosphorus. After grinding and alkaline boiling, it is washed, dehydrated, and dried to obtain the finished red phosphorus. The entire red phosphorus production process consists of conversion, ball milling, alkaline boiling, washing, dehydration, drying, and packaging.

[0003] For example, patent document with publication number "CN119306189A" discloses a process for producing red phosphorus using a high-temperature closed method, including S1, yellow phosphorus preparation; S2, melting; S3, high-temperature conversion; S4, pulverization; S5, alkaline boiling; S6, rinsing and filtering; S7, dehydration; and S8, drying. Using this patented technology, phosphine gas can be generated in a short time with stable quality, and a slurry containing red phosphorus particles with minimal dissolution of phosphorus oxyacids can be obtained. Furthermore, the red phosphorus particles obtained from the method of manufacturing the slurry containing red phosphorus particles can be used as raw materials to obtain stabilized red phosphorus that effectively suppresses the generation of phosphine gas and the dissolution of phosphorus oxyacids. The entire preparation process reduces labor intensity, improves production efficiency, and ensures production safety.

[0004] However, yellow phosphorus has a low ignition point, generally burning at around 40°C. In industrial enterprises, to properly store yellow phosphorus, powdered yellow phosphorus is usually stored in water, as it is almost insoluble in water. The storage area should be cool, ventilated, and dry, with a temperature not exceeding 35°C. In large enterprises, the yellow phosphorus storage warehouse and the conversion workshop are far apart, and the working conditions in the two places are completely different. During the production process, the yellow phosphorus in the warehouse needs to be transferred to the corresponding conversion pot, and then the conversion pot and yellow phosphorus are transferred together to the conversion workshop. Under the corresponding production conditions, the yellow phosphorus is converted into red phosphorus. Because yellow phosphorus has an extremely low ignition point, the transfer and transportation process of yellow phosphorus should avoid contact with air and personnel contact with yellow phosphorus to prevent safety accidents.
