Description

Technical Field

[0001] This invention belongs to the technical field of red phosphorus production equipment, and particularly relates to an industrial yellow phosphorus filling and transfer device. 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. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an industrial yellow phosphorus filling and transfer device.

[0006] This invention provides an industrial yellow phosphorus filling and transfer device, including a yellow phosphorus storage tank, a water tank, a main phosphorus conveying pipe, a branch phosphorus conveying pipe, and a driving mechanism. The driving mechanism includes a truss and a lifting slider. The lifting slider is fixedly connected to the truss, and the truss is fixedly connected to the branch phosphorus conveying pipe. The driving mechanism is used to move and switch one end of the branch phosphorus conveying pipe between the water tank and the conversion pot. The other end of the branch phosphorus conveying pipe is connected to the main phosphorus conveying pipe. The main phosphorus conveying pipe is also connected to one end of a follow-up hose, and the other end of the follow-up hose is connected to the yellow phosphorus storage tank.

One end of the hoop plate is hinged to one side of the limiting groove opening. When the other end of the hoop plate is fixed to the other side of the limiting groove opening, the phosphorus conveying branch pipe is clamped between the hoop plate and the limiting groove.

[0012] The industrial yellow phosphorus filling and transfer device also includes a pressure plate. The surface of the lifting slider is provided with a clamping groove. One end of the pressure plate is fixed to one side of the clamping groove opening. When the other end of the pressure plate is fixed to the other side of the clamping groove opening, the truss is clamped between the pressure plate and the clamping groove.

[0013] The truss can be replaced by a rectangular steel tube.

The first motor is fixedly connected to the base, and the output shaft of the first motor is fixedly connected to one end of the first lead screw. The other end of the first lead screw is mounted on the base using a rolling bearing. The translation slider is sleeved on the first lead screw. The second motor is fixedly connected to the translation slider, and the output shaft of the second motor is fixedly connected to one end of the second lead screw. The other end of the second lead screw is mounted on the translation slider using a rolling bearing. The lifting slider is sleeved on the second lead screw.

[0015] The industrial yellow phosphorus filling and transfer device also includes a positioning plate inserted into the ground, with at least one side of the positioning plate abutting against the side of the conversion pot.

[0016] The beneficial effects of this invention are as follows: When yellow phosphorus needs to be transferred to the conversion pot using the technical solution provided by this invention, the conversion pot is placed at a predetermined position, and the end of the phosphorus conveying branch pipe is extended into the conversion pot by the driving mechanism. Yellow phosphorus is transported from the storage tank to the conversion pot. After the yellow phosphorus is transported, the driving mechanism lifts the end of the phosphorus conveying branch pipe and extends it into the water tank. The water tank contains warm water at a suitable temperature. The warm water seals the end of the phosphorus conveying branch pipe, preventing outside air from contacting the yellow phosphorus. This isolates the yellow phosphorus from the air as much as possible, reduces safety hazards, and ensures production safety and personnel safety. Attached Figure Description
