Mixer of serum materials

Abstract

A serum material mixer is provided, which relates to a device for mixing fluid material in the process of metallurgy chemical engineering, in particular to a high and low temperature material mixing device for the mash and lye while stripping in producing hydrafil and alumina. The basic structure of the mixer is a T-shaped three-way steel work, which is characterized in that: a material flow guide cone object is arranged in the mixer, the bottom of guide cone object is placed in the middle and on the wall of two through material serum flow and material liquid flow feeding tube, the conical surface of the guide cone object to the opening the feeding tube is an arc surface on the feeding tube with the surface tangent to the surface of the feeding tube; the radian of the arc surface is same to that of an arc at the cross of the level feeding tube and the mixing output tube. A material guide awl is arranged in the mixer, which can make the tangential of the material cross and enter into a stripping machine after full mixing, the vortex won't happen and reduces abrasion, suction and shake. The invention solves the problem that two material flows has different content, different temperature and are easy to cause shaking when contacting, and three material at medium temperature after mixing and at high and low temperature causes welding interface breakage and crossing and pre-aerating.

Description

technical field [0001] A slurry material mixer relates to a device for mixing fluid materials in a metallurgical and chemical process, in particular to a device for mixing high-temperature and low-temperature materials of ore pulp and lye during Bayer process production of aluminum hydroxide and aluminum oxide dissolution. technical background [0002] In the process of metallurgy and chemical industry, it is often necessary to mix two fluid materials with different concentrations and different temperatures. In the high-pressure dissolution process of producing alumina by the Bayer process, all the lye required for the active ingredients in the bauxite and the dissolution ore is often ground into a qualified slurry. After batching, a high-pressure pump is used to pass through the preheater (heater) Feed to the dissolver. Due to the precipitation of scars during the preheating of the pulp and the process of heating and stripping, it will have an adverse effect on the product...
