Flotation separation device for preparing boric acid from boron ore

Abstract

The invention discloses a flotation separation device for preparing boric acid from boron ore. The flotation separation device comprises a flotation bin, a cover plate, an overflow port, a centrifugalassembly, a collecting bin, a foam scraping assembly, an overturning assembly, a liquid storage bin and a feeding assembly, and the centrifugal assembly comprises a rotating shaft, an impeller and amotor. The flotation separation device has the beneficial effects that the collecting bin is arranged, and foam scraped out by the foam scraping assembly is scraped into the collecting bin to be collected; the overturning assembly is arranged, the sealing cover plate is driven by the overturning assembly to overturn, and the sealing cover plate does not need to be opened manually; the liquid storage bin is arranged, and a flotation agent needed in the flotation operation process can be stored; the communication between a communicating pipe and a communicating bin is controlled by the feeding assembly, so that the flotation agent can enter the communicating pipe from the communicating bin and then flow into the flotation bin; and in conclusion, compared with flotation equipment in the priorart, the flotation separation device has the advantages that the functions are diversified, the operation is convenient and fast, and the working efficiency is further improved.

Description

technical field

[0001] The invention relates to the field of flotation equipment, in particular to a flotation separation device for preparing boric acid from boron ore. Background technique

[0002] Boric acid is an inorganic substance with the chemical formula H 3 BO 3 , is a white powdery crystal or triclinic scale-like shiny crystal, with a smooth feel and no odor. Soluble in water, alcohol, glycerin, ethers and essential oils, the aqueous solution is weakly acidic. It is widely used in the glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber for insulating materials) industry, which can improve the heat resistance and transparency of glass products, increase the mechanical strength, and shorten the melting time.

[0003] When extracting boron ore, boron ore is generally crushed into pulp, and then separated by flotation through flotation equipment, but the existing flotation equipment has the problems of single function and low work efficienc...
