Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of potassium fluoride production equipment, specifically, the utility model relates to a kind of automatic feeding device of potassium fluoride. BACKGROUND

[0002] Potassium fluoride is a widely used fluorinating agent, which can participate in many organic chemical reactions. However, potassium fluoride is a toxic material that can cause severe damage to mucous membranes, upper respiratory tract, eyes, and skin tissue. Inhaling it can be fatal, and symptoms of poisoning include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. In actual production, very small particle size active potassium fluoride is usually used. However, due to the small particle size of active potassium fluoride, it has good flowability and is easy to produce dust during feeding, which can be contacted or inhaled by operators. Additionally, active potassium fluoride is highly hygroscopic and deliquescent. The moisture absorbed by potassium fluoride can reduce the reaction yield, and the water brought in can combine with potassium fluoride to release hydrogen fluoride gas, causing corrosion of equipment, pipelines, and instruments.

[0003] Therefore, direct contact between potassium fluoride and the human body should be avoided during use, and moisture should not be absorbed. However, the commonly used feeding methods such as manual feeding, pump delivery, and auger delivery have varying degrees of the above problems. In addition, the feeding process of potassium fluoride is usually accompanied by the feeding of other materials, and the feeding of single material affects the production efficiency.
