Ardealite flotation device

Abstract

The invention belongs to the technical field of ardealite treatment, particularly relates to an ardealite flotation device, and provides the following scheme for solving the problems in the prior artthat: the ardealite flotation device comprises a flotation cylinder, a liquid guide shell is arranged on the outer wall of the bottom of the flotation cylinder, a lower liquid shell is fixedly connected to the outer wall of one side of the liquid guide shell, a flow guide shell is fixedly connected to the bottom outer wall, a heating shell is fixedly connected to the outer wall of one side of theflow guide shell, a dirt collecting shell is fixedly connected to the outer wall of one side of the heating shell, a dirt collecting box is placed on the inner wall of the bottom of the dirt collecting shell, and a dirt discharging door is arranged on the outer wall of one side of the dirt collecting shell. By means of the ardealite flotation device, water can be purified, it is avoided that impurities in water are dissolved and saturated to lose the impurity removal effect, the remaining impurities on the heating shell can be scraped into the dirt collecting box, it is avoided that the impurities adhere to the interior of the heating shell to affect evaporation of subsequent water, water in the flotation barrel can be heated, the solubility of ardealite is reduced, and the loss of ardealite is reduced.

Description

technical field [0001] The invention relates to the technical field of phosphogypsum treatment, in particular to a phosphogypsum flotation device. Background technique [0002] Phosphogypsum: refers to the solid waste residue produced when sulfuric acid is used to treat phosphate rock in the production of phosphoric acid. Its main component is calcium sulfate. Phosphogypsum is generally powdery, and its appearance is generally grayish white, grayish yellow, light green and other colors. It also contains organic Phosphorus, sulfur and fluorine compounds, the bulk density is 0.733-0.88g / cm3, the particle diameter is generally 5-15um, and its main component is calcium sulfate dihydrate, and its content can generally reach about 70-90%, and the secondary components contained in it are Depending on the origin of phosphate rocks, they generally contain phosphates and silicates of rock components Ca and Mg. At present, my country discharges about 20 million tons of phosphogypsum ever...

AI Technical Summary

Problems solved by technology

[0003] However, phosphogypsum can be made into fertilizer or mixed into cement for recycling. When phosphogypsum is used, phosphogypsum needs to be flotation cleaned to remove impurities in phosphogypsum. However, when the existing flotation devices are used , when the soluble impurities dissolve into the water, it will lead to the gradual saturation of the water, which will lead to poor subsequent dissolution effect and reduce the effect of impurity removal
