Abstract

The invention discloses high-vacuum low-temperature crystallization equipment for potassium perchlorate production, which belongs to the field of chemical equipment and comprises a tank body, a vacuumevaporation area, a crystallization area and a settling separation area are sequentially arranged in the tank body from top to bottom, and the vacuum evaporation area communicates with the crystallization area through a spraying device. The crystallization area communicates with the settling separation area through a material releasing pipe; a stirring shaft penetrating through the vacuum evaporation area and the crystallization area and a first driving device used for driving the stirring shaft to rotate are arranged in the tank body; a first stirring blade and a second stirring blade are arranged on the stirring shaft, hollow cavities which communicate with each other are formed in the stirring shaft and the second stirring blade in the crystallization area, air guide pipes connected with a cooling air source are arranged in the hollow cavities, and the hollow cavities are filled with cooling liquid; an air injection assembly is arranged on the second stirring blade; and the evaporation speed of the vacuum evaporation area is high, the production efficiency is improved, and the invention further discloses a using method of the equipment.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a high-vacuum low-temperature crystallization equipment for potassium perchlorate production and a use method thereof. Background technique [0002] Potassium perchlorate, also known as potassium perchlorate, is the potassium salt of perchloric acid with the chemical formula KClO 4 It is a colorless crystal or white powder with a melting point of about 610°C. It is often used as an oxidizer in pyrotechnics and flash powder, and is also used as a primer. It can be used as one of the solid rocket propellant materials and is widely used. widely. [0003] Potassium permanganate is electrolyzed to produce potassium permanganate, and the potassium permanganate crystal discharged from the cell is still the primary product, which is too alkaline and has a small amount of mechanical impurities. After one or more times of dissolution, heating, clarification, and separation of impurities...
