[0002] Muddy phosphorus is usually a by-product in the process of processing phosphate rock. By extracting yellow phosphorus, the originally wasted resources can be transformed into valuable products, realizing the recycling of resources. Environmental protection benefits: Traditional methods for producing yellow phosphorus may generate a large amount of waste and pollutants, while extracting yellow phosphorus from muddy phosphorus can reduce the impact on the environment and is a more environmentally friendly production method. After a large number of searches, the publication number is CN1218869C, which discloses a production method for recovering yellow phosphorus from muddy phosphorus and a device for realizing this method.

The design of the whole device ensures that the entire process from the extraction to the transmission of yellow phosphorus is carried out in a sealed or controllable environment, greatly reducing the risk of yellow phosphorus contacting the air, and achieving the effect of improving the safety of the extracted yellow phosphorus during the transmission process.

[0027] Example Two

[0028] To increase the vaporization rate of yellow phosphorus, as Figure 1 and Figure 2 shown, in this embodiment, the bottom end of the bin body 1 is recessed towards the center and is connected and installed with a slag discharge pipe 14.

This intelligent control method can accurately adjust the intake air volume according to actual needs, thereby optimizing the yellow phosphorus extraction process. At the same time, the connection and installation with the gas heat source pipeline ensure the stable supply of the heat source gas and provide the necessary heat energy for the vaporization of yellow phosphorus.

[0030] Furthermore, the rear end of the transmission shaft 12 passes through the bin body 1 and is drivingly installed with a driving motor 11. The driving motor 11 is fixedly installed on the outer wall on the other side of the bin body 1. In the design, the connection between the rear end of the transmission shaft 12 and the driving motor 11 realizes the effective transmission of power. The fixed installation of the driving motor 11 not only saves space but also improves the stability and efficiency of the entire transmission system. This design enables the stirring frame 13 to operate continuously and stably, providing a guarantee for the uniform heating of the muddy phosphorus and the full vaporization of yellow phosphorus.

[0031] Furthermore, a pressure gauge 10 is installed by opening a hole on one side of the upper surface of the cover body 9 and embedding it. The pressure gauge 10 adopts a high-temperature resistant pressure gauge 10 structure design. In the design, the high-temperature resistant pressure gauge 10 embedded in the cover body 9 can monitor the pressure change inside the bin body 1 in real time, ensuring that the operation is carried out within a safe pressure range. This high-temperature resistant design enables the pressure gauge 10 to work stably in a high-temperature environment, improving the measurement accuracy and the safety of the device.

[0032] Example Three

[0033] To improve the sealing performance of the container during the yellow phosphorus transportation stage and facilitate the operator to understand and control the yellow phosphorus extraction situation, as Figure 3 and Figure 4As shown, in this embodiment, a discharge valve 16 is fixedly installed at the top of the condenser tube 4. The discharge valve 16 is designed with a manual angle valve structure. A first quick connector 17 is fixedly installed at the bottom end of the condenser tube 4. In the design, the discharge valve 16 at the top of the condenser tube 4 is designed with a manual angle valve structure, making the discharge operation of yellow phosphorus more convenient and fast. The installation of the first quick connector 17 provides the functions of quick connection and disconnection, improves the discharge efficiency, and also facilitates the maintenance and cleaning of the equipment.

[0034] Furthermore, a viewing window 20 is installed by grooving and embedding on one side of the storage bin 6. The viewing window 20 is designed with tempered glass material. A second quick connector 18 is connected and installed through a sealing valve 19 on the upper end face of the storage bin 6.

The matching design of the second quick connector 18 and the first quick connector 17 realizes the fast and safe transmission of yellow phosphorus, improving the efficiency of the entire extraction and transmission process.

[0035] When the utility model is in use, close the valve on the slag discharge pipe 14 and open the valve on the feed pipe 2. Convey the muddy phosphorus raw material into the bin body 1 through the feed pipe 2. Convey the heated protective gas into the bin body 1 through the air inlet pipe 15. The air inlet valve 7 is designed with an electric control valve structure to ensure the precise control of the gas flow. Start the drive motor 11, drive the stirring frame 13 to rotate through the transmission shaft 12, and realize the stirring and mixing of the muddy phosphorus. At the same time, heat and flush the muddy phosphorus in the bin body 1 through the gas heat source pipeline to promote the vaporization of yellow phosphorus. Under the action of heating and stirring, yellow phosphorus gradually vaporizes to form phosphorus-containing steam. The phosphorus-containing steam rises through the connecting pipe 3 to the reserved hole 8 of the cover body 9 and enters the condenser tube 4. The condenser tube 4 is designed with a spiral structure, which is beneficial to the cooling and condensation of the steam. After the yellow phosphorus steam is cooled in the condenser tube 4, it gradually condenses into solid yellow phosphorus. The condensed yellow phosphorus flows into the storage bin 6 through the bottom end of the condenser tube 4 for storage. And an appropriate amount of clear water has been injected into the storage bin 6 in advance to isolate the contact between yellow phosphorus and air. The pressure in the bin body 1 can be monitored through the pressure gauge 10 to ensure that the operation is within a safe range. After the purification is completed, open the valve on the slag discharge pipe 14 to discharge the non-yellow phosphorus components in the muddy phosphorus from the bin body 1. If necessary, open the pressure relief valve 21 to release the pressure in the bin body 1. Separate the storage bin 6 from the condenser tube 4, so as to transport the storage bin 6. And after arriving at the placement location, the discharge valve 16 can be opened to discharge the yellow phosphorus in the storage bin 6 for subsequent collection or further processing.
