Vacuum agitating device for original-state titanium gypsum slag slurry

Abstract

The invention discloses a vacuum agitating device for original-state titanium gypsum slag slurry. The vacuum agitating device consists of a transmission part, a slurry powder agitating chamber, a vacuum chamber, an aggregate agitating chamber and a rack, wherein the transmission part consists of a transmission motor and a speed reducer; two output shafts of the speed reducer are respectively connected with a slurry powder agitating spiral shaft of the slurry powder agitating chamber and an aggregate agitating spiral shaft of the aggregate agitating chamber through shaft couplers; the slurry powder agitating chamber and the aggregate agitating chamber are arranged on the upper and lower layers; the vacuum chamber is located between the two chambers, so that the two chambers are connected into a whole; and an agitating-in part and a sludge extrusion part of the aggregate agitating chamber are located on the same layer, and use the same aggregate agitating spiral shaft. The vacuum agitating device is simple in structure and convenient to use; and after agitated titanium gypsum slag slurry and powder are uniformly agitated under a sealed condition, the mixture enters the vacuum chamber, then aggregates are added, and vacuum agitating is carried out to fulfill the aims of uniform agitating, compact particle accumulation and exhausting of air.

Description

technical field [0001] The invention relates to the technical field of building material batching and mixing machinery, in particular to a vacuum stirring device for producing titanium gypsum slag building materials. Background technique [0002] Titanium dioxide production enterprises adopt the method of lime neutralization reaction in the process of processing a large amount of waste liquid containing sulfuric acid, so a large amount of industrial waste residue containing calcium sulfate dihydrate, that is, titanium gypsum slag, will be produced. Every ton of titanium dioxide produced requires 1.5-2 tons of titanium gypsum slag is discharged. Its chemical composition and physical properties are similar to natural gypsum, but because it contains certain impurities and has a large amount of attached water, it is easy to agglomerate after drying and dehydration, which brings great difficulty to its comprehensive utilization. At present, there are two ways to comprehensively u...

Problems solved by technology

[0003] If the original titanium gypsum slag is directly used as the raw material of building materials, and other powdery ingredients and granular ingredients are directly stirred into the slurry titanium gypsum slag, which simplifies the mixing process, the cost of building materials can be greatly reduced, but the original gypsum When the slag is stirred into the powder, a large number of air bubbles will be introduced due to the long stirring time, and a large number of air bubbles will also be replaced by the continuous introduction of the aggregate. result in severe performance degradation, so there is an urgent need to develop a stirring device
