Description

Technical Field

[0001] The utility model relates to a potassium fluoride feeding device, belonging to the technical field of chemical production. Background Art

[0002] Potassium fluoride is one of the most commonly used fluorinating agents and the most widely used metal fluoride salt. It can be said that without potassium fluoride, there would be no booming Chinese fluorine chemical industry.

[0003] Because potassium fluoride has a strong water absorption capacity and easily deliquesces when in contact with moist air, it is best to avoid exposing it to air during feeding. Currently, potassium fluoride is mainly fed manually in the industry by opening the reactor inlet and directly adding potassium fluoride to the reactor. This method is not only labor-intensive, but also requires a high workload for operators, which can also degrade the workshop working environment. Potassium fluoride dust will spread throughout the workshop, and it can also endanger the health of operators.

It includes a glove box main body, a main hatch, a transition hatch, gloves, a transition hatch nitrogen inlet, a transition hatch exhaust, a transition hatch pressure gauge, a feeding hatch nitrogen inlet, a feeding hatch exhaust, a feeding hatch pressure gauge, and a discharge port. The glove box main body is tilted 5° from left to right and has a discharge port at its lowest point. The discharge port is equipped with a discharge valve and is connected to the reactor via a powder diaphragm pump. A feed valve is also installed between the powder diaphragm pump and the reactor. Several gloves are installed on the glove box main body, and a main hatch is located on one side of the glove box main body.
