Once the humidity is higher than the set safety humidity value H max When the air is cooled, the fan 200 is started, the third valve 2005 and the fourth valve 2007 are opened, and the second valve 2003 and the fifth valve 2009 are closed, so that the fan 200 sucks out the humid air and discharges it through the fourth pipe 2006; then, the third valve 2005 and the fourth valve 2007 are closed, and the second valve 2003 and the fifth valve 2009 are opened, and the fan 200 can suck in the outdoor air and transport it to the dehumidifier, and introduce the dry air treated by the air dehumidifier 300 into the inner frame 1006 for recycling.
[0063] Among them, multiple groups of temperature sensors are also fixedly installed in the inner frame 1006, and the control unit is a controller;
[0064] The controller is used to adjust the heating power of the infrared heating tube 1001, and the specific adjustment calculation formula is as follows:
[0065]
[0066] When the temperature is higher than the set upper limit temperature T max When the temperature is lower than the set lower limit temperature T min When , the controller increases the heating power;
[0067] Among them, the mass of yellow phosphorus is m (unit: kg), the specific heat capacity of yellow phosphorus is c (unit: J / (kg·℃)), and the initial temperature is T 1(单位 ℃), the target drying temperature is T2 (unit: ℃), the drying time is t (unit: s), and the heating power of the infrared heating tube 1001 is P (unit: W).
[0068] Among them, multiple groups of humidity sensors are fixedly installed in the inner frame 1006, and the controller is used to adjust the humidity in the inner frame 1006. The specific adjustment calculation formula is as follows:
[0069] m w =ρ×V×(H1-H2)
[0070] E=m w ×L
[0071] When the humidity is higher than the set safe humidity value H max When the air is exhausted, the fan 200 starts to discharge the moist air and introduce the dry air treated by the air dehumidifier;
[0072] The volume of the inner frame 1006 is V (unit: m 3 ), the initial humidity is H1 (unit: %), the target humidity is H2 (unit: %), and the density of air is ρ (unit: kg / m 3 ), the latent heat of vaporization of water is L (unit: J / kg), and the mass of water discharged is m w (Unit: kg), the energy required for dehumidification is E (Unit: J).
[0073] The controller also adjusts the vacuum pump 400 to adjust the vacuum level in the drying box 100. The specific adjustment calculation formula is as follows:
[0074]
[0075] Among them, the initial water content of yellow phosphorus is m w1 (unit: kilograms), the adsorption capacity of molecular sieve material for water is C (unit: kilograms per cubic meter), the filling volume of molecular sieve material is V (unit: cubic meter); after a period of time t1 (unit: seconds), the water content of yellow phosphorus is m w2 (Unit: kg), when the molecular sieve material is close to saturation, start the vacuum pump 400 to reduce the pressure in the drying box 100 to P vac (Unit: Pascal), under vacuum environment, the boiling point of water is greatly reduced, and it is easier to evaporate from the surface of yellow phosphorus and be adsorbed by the molecular sieve.
[0076] In order for those skilled in the art to fully understand the technical solution, the working principle of this embodiment is as follows:
[0077] When in use, the yellow phosphorus is transported to the drying box 100 through the feeding pipe 1004 and falls into the storage box 600. At the same time, the infrared heat pipe is turned on for heating and drying. During drying, the second electric push rod 7003 can be started to work. The second electric push rod 7003 pushes the push pipe 700 to slide. The push pipe 700 pushes the storage box 600 to reciprocate in the drying box 100 through the spring 7005. At the same time, the adjusting protrusion 6001 will continuously contact the arc-shaped protrusion 1002, so that the storage box 600 can vibrate in the inner frame 1006, and the yellow phosphorus in the storage box 600 is flattened, which is convenient for further drying.
[0078] During the drying process, the humidity can be detected by the humidity sensor. Once the humidity is higher than the set safe humidity value H max When the fan 200 is started, the third valve 2005 and the fourth valve 2007 are opened, and the second valve 2003 and the fifth valve 2009 are closed, so that the fan 200 sucks out the humid air and discharges it through the fourth pipe 2006;
[0079] Then, the third valve 2005 and the fourth valve 2007 are closed, and the second valve 2003 and the fifth valve 2009 are opened, so that the fan 200 can suck in the outdoor air and transport it to the dehumidifier, and introduce the dry air treated by the air dehumidifier 300 into the inner frame 1006 for recycling;
[0080] At the same time, during the drying process, the humidity can be detected by the temperature sensor. When the temperature is higher than the set upper limit temperature T max When the temperature is lower than the set lower limit temperature T min When , the controller increases the heating power;
[0081] In addition, the moisture in the yellow phosphorus can be adsorbed by the molecular sieve material. Once the molecular sieve material is close to saturation, the vacuum pump 400 is started to reduce the pressure in the drying box 100 to P. vac (Unit: Pascal), in a vacuum environment, the boiling point of water is greatly reduced, and it is easier to evaporate from the surface of yellow phosphorus and be adsorbed by the molecular sieve, increasing the drying effect;
[0082] After the drying is completed, the storage box 600 is pushed to one side of the spiral conveying auger 500 by the second electric push rod 7003, so that the feeding end of the spiral conveying auger 500 enters the discharge port 6004, and the yellow phosphorus is transported away by the spiral conveying auger 500. At the same time, the first electric push rod 7002 can be started to drive the piston rod 7001 to slide, and the electromagnet 7004 hit by the piston rod 7001 slides and enters the storage box 600 through the through hole 7006, and is fixed by the electromagnet 7004 and the push plate 7007 through adsorption, and the push plate 7007 is pushed to slide by the piston rod 7001, and the yellow phosphorus is pushed to the bottom of the spiral conveying auger 500 by the push plate 7007;
[0083] After completion, the first electric push rod 7002 drives the piston rod 7001 to retract, and at the same time the electromagnet 7004 is powered off, and the push plate 7007 is adsorbed on the outside of the porous frame 6002 again through the magnet block 7008.
[0084] In summary, the excellent safety of this equipment greatly reduces the risk of spontaneous combustion and leakage of yellow phosphorus through intelligent temperature control, precise humidity adjustment and efficient sealing measures, providing reliable safety protection for operators and the surrounding environment. It can accurately control various parameters in the drying process, so that the moisture content of yellow phosphorus can be steadily reduced to a low level, thereby improving the quality and purity of yellow phosphorus products. Through precise power control of infrared heating tube 1001, vacuum dehumidification technology and optimized airflow circulation design, it improves energy utilization, reduces energy consumption and reduces production costs.
