[0002] Anhydrous hydrogen fluoride, as a key chemical raw material, occupies an important position in many fields such as fluorochemicals, electronics, and metallurgy. After hydrogen fluoride production, fluorogypsum is generated. Because fluorogypsum is in powder form and contains residual acidic substances, it needs to be humidified and an alkaline substance added to neutralize the acidic substances before loading. In existing technology, lime slurry is generally used as the alkaline substance. Lime slurry is added to the equipment conveying fluorogypsum, allowing it to react with the lime slurry during transportation and increasing the humidity of the fluorogypsum to prevent dust generation during loading. However, lime powder has low solubility, resulting in a high water content in the lime slurry, which significantly increases the water content of the fluorogypsum. This makes leakage during loading and transportation highly likely, polluting the environment. Furthermore, the alkaline components in the lime slurry corrode equipment, increasing maintenance costs, shortening equipment lifespan, and seriously affecting the stability and continuity of production.

One end of the neutralization conveyor structure 3 is connected to the other end of the mixing conveyor structure 1. The humidification structure 4 is connected to the other end of the neutralization conveyor structure 3, and the humidification structure 4 has a spray assembly inside. The outlet of the humidification structure 4 is located above the loading station 5.
[0028] In this embodiment, fluorogypsum is transported via a fluorogypsum conveying structure. One end of the mixing conveying structure 1 is connected to the fluorogypsum conveying structure, allowing the fluorogypsum to enter the mixing conveying structure 1. A dry lime storage tank 2 is connected to the mixing conveying structure 1, allowing the dry lime powder in the dry lime storage tank 2 to enter the mixing conveying structure 1 and mix with the fluorogypsum. Preferably, the mixing conveying structure 1 is a screw conveyor. The fluorogypsum and dry lime powder can be fully mixed within the mixing conveying structure 1, initiating a neutralization reaction. The mixed fluorogypsum and dry lime powder are then conveyed by the mixing conveying structure 1 to the neutralization conveying structure 3. Within the neutralization conveying structure 3... Fluorogypsum and dry lime powder will continue to undergo a neutralization reaction. The neutralization conveying structure 3 conveys the fluorogypsum and dry lime powder to the humidification structure 4. The spraying components (not shown) in the humidification structure 4 can spray water on the mixture formed by the fluorogypsum and dry lime powder, thereby increasing the humidity of the mixture. The humidification structure 4 is also a screw conveyor. The humidification structure 4 can stir and convey the mixture when the spraying components spray water. The outlet of the humidification structure 4 is located above the loading station 5. The transport vehicle is parked in the loading station 5. The hopper of the transport vehicle is located below the loading station 5. The mixture discharged from the outlet of the humidification structure 4 can fall into the hopper of the transport vehicle.
[0029] Preferably, the neutralizing conveying structure 3 is a bucket elevator.
[0030] It should be noted that by mixing dry lime powder and fluorogypsum through the mixing and conveying structure 1, the residual acid in the fluorogypsum can be precisely neutralized, and the water content of the fluorogypsum can be effectively reduced, thereby significantly reducing the risk of leakage, ensuring the safety of the production environment. At the same time, it can also avoid equipment corrosion problems caused by alkaline substances in lime milk, extend the service life of equipment, reduce equipment maintenance costs, and improve the sustainability of production.
[0031] In one embodiment, the system further includes a quantitative conveying structure 6, which is disposed between the neutralizing conveying structure 3 and the humidifying structure 4. One end of the quantitative conveying structure 6 is connected to the neutralizing conveying structure 3, and the other end of the quantitative conveying structure 6 is connected to the humidifying structure 4.
[0032] In this embodiment, as Figure 1 As shown, the quantitative conveying structure 6 is a screw conveyor. The mixture formed by fluorogypsum and dry lime powder in the neutralization conveying structure 3 first enters the quantitative conveying structure 6, and is then conveyed by the quantitative conveying structure 6 to the humidification structure 4. The quantitative conveying structure 6 includes a motor, and the conveying capacity of the quantitative conveying structure 6 can be adjusted by modifying the output power of the motor. The quantitative conveying structure 6 can precisely control the feeding speed of the mixture, avoid clogging of the humidification structure 4, and ensure stable operation of the equipment. At the same time, the quantitative conveying structure 6 can increase the reaction time between fluorogypsum and dry lime powder, improving the processing efficiency and quality of fluorogypsum.
[0033] In this embodiment, as Figure 1As shown, the quantitative conveying structure 6 is connected to a controller, which controls the conveying volume of the quantitative conveying structure 6. Preferably, the controller (not shown) is a PLC controller, which is connected to the motor signal of the quantitative conveying structure 6. The PLC controller has a human-machine interface, and the operator can adjust the conveying volume of the quantitative conveying structure 6 through the human-machine interface by observing the number of times the humidification structure 4 jams. When the number of jams is high, that is, there is a blockage in the humidification structure 4, the conveying volume of the quantitative conveying structure 6 needs to be reduced.
[0034] In one embodiment, it further includes: a mixing bin 7, which is located between the neutralizing conveying structure 3 and the metering conveying structure 6, with the inlet of the mixing bin 7 connected to the neutralizing conveying structure 3 and the outlet of the mixing bin 7 connected to the metering conveying structure 6.

The neutralization conveying structure 3 is connected to the inlet of mixing silo 7, and the outlet of mixing silo 7 is connected to the quantitative conveying structure 6. The outlet of mixing silo 7 has a control valve (not shown), which is connected to a PLC controller. When material blockage occurs, the operator can control the control valve to close via a human-machine interface, simultaneously reducing the conveying capacity of the quantitative conveying structure 6. Mixing silo 7 can store a mixture of fluorogypsum and dry lime powder, and can increase the reaction time between fluorogypsum and dry lime powder, making the reaction more thorough.
[0036] In this embodiment, as Figure 1 As shown, it also includes: a dry lime powder conveying structure 8, one end of which is connected to the dry lime storage tank 2, and the other end of which is connected to the mixing conveying structure 1. The dry lime powder conveying structure 8 can convey the dry lime powder in the dry lime storage tank 2 to the mixing conveying structure 1. Preferably, the dry lime powder conveying structure 8 is a screw conveyor.
[0037] In this embodiment, as Figure 1 As shown, the fluorogypsum conveying structure includes a cooling structure 9, the outlet end of which is connected to the mixing conveying structure 1.

Each of the multiple water atomizing structures is connected to an external water supply device via a water pipe. Preferably, the water atomizing structure (not shown) is an atomizing nozzle, which is connected to the external water supply device (not shown) via a water pipe (not shown). The atomizing nozzle atomizes water and sprays it out, thereby increasing the humidity of the mixture within the humidification structure 4 and preventing dust from being generated during loading. The number of water atomizing structures can be determined based on the size of the humidification structure 4, the humidity of the mixture, etc., and is not specifically limited here.
[0039] In one embodiment, at least one level gauge 10 is provided in the dry lime storage tank 2.
[0040] In this embodiment, as Figure 1 As shown, two level gauges 10 are installed in the dry lime storage tank 2.
