Description

Technical Field

[0001] This utility model relates to the field of molten phosphorus supply technology, specifically to a molten phosphorus supply device. Background Technology

[0002] Phosphorus pentasulfide is an inorganic compound with the chemical formula P2S5. It is a yellow solid that is stable when dry, but it hydrolyzes in water to form phosphoric acid and hydrogen sulfide, which is why it smells like rotten eggs in the air.

[0003] There are two main methods for producing phosphorus pentasulfide: direct synthesis and indirect synthesis.

[0004] Among them, the direct synthesis method:

[0005] After melting yellow phosphorus and sulfur separately, they are continuously added to a reaction tube maintained at a certain temperature according to the mass ratio of sulfur to phosphorus (2.57~2.6):1.

[0006] The reaction temperature is maintained at approximately 300–400°C. After the reaction is complete, the mixture is transferred to an intermediate tank and stirred until it cools to 300°C. Then, it is placed in a drum tableting machine to produce phosphorus pentasulfide.

[0007] Currently, the method of heating and melting phosphorus for supplying phosphorus is prone to uneven heating and unstable delivery of yellow phosphorus. At the same time, the phosphorus melting process produces residues that are inconvenient to clean up. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a molten phosphorus supply device to solve the problems mentioned in the background art, such as uneven heating and unstable yellow phosphorus delivery caused by the current method of heating and melting during phosphorus supply, as well as the inconvenience of cleaning up residues generated during phosphorus melting.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a molten phosphorus supply device, comprising a supply tank, a boiler, and a base. A tank cover is sealed to the outer surface of the supply tank. A servo motor is mounted on the outer surface of the tank cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This molten phosphorus supply device operates by controlling a servo motor, which drives a fixed roller to rotate. This causes several agitators to tumble and stir the yellow phosphorus in the supply tank.
