Blending and mixing groove

Abstract

The invention discloses a material blending device, in particular to a blending and mixing groove. The blending and mixing groove comprises a groove body, wherein the middle part of the groove body is provided with a stirring shaft; the groove body is provided with a liquid outlet and a feed port; a liquid blocking plate is arranged in the groove body; the lower part of the liquid blocking plate is provided with an inverted whirl groove; one end of a whirl plate is inserted into the whirl groove, and the other end of the whirl plate is fixed with the inner wall of the bottom of the groove body; both sides of the whirl plate are fixed with the inner wall of the side of the groove body; and the liquid blocking plate and both sides of the whirl groove are fixed with the inner wall of the side of the groove body. The blending and mixing groove has the advantages of blending and mixing component mother liquor, evaporation mother liquor and caustic soda liquid with different specific gravities and different concentrations in the blending and mixing groove with the stirring shaft and a mixing baffle plate, increasing mixing time of alkali liquor in the blending and mixing groove with the liquid blocking plate and the whirl plate, and mixing the alkali liquor with different specific gravities and different concentrations to make the concentration of the mixed alkali liquor reach the concentration meeting the requirements as much as possible.

Description

technical field [0001] The invention relates to a material mixing device, in particular to a blending and mixing tank for mixing various lyes with different specific gravity and different concentrations to meet the needs of the production process of the alumina pre-desilication process. . Background technique [0002] Pre-desilication is an important process in the production process of alumina. Because the lye that enters the pre-desilication comes from the seed separation mother liquor, the evaporation mother liquor and the liquid alkali; the specific gravity and the concentration of the seed separation mother liquor, the evaporation mother liquor and the liquid alkali are different, so it is very easy to make the concentration of the lye too high or too low. Affect the production of alumina in pre-desilication and post-desilication processes. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the invention provides a blending ...
