Calcium carbonate processing drying device for preventing calcium carbonate slurry from caking

Abstract

The invention discloses a calcium carbonate processing drying device for preventing calcium carbonate slurry from caking. The calcium carbonate processing drying device comprises a rotating motor, a stirring rod, an air heater and a bottom cover, wherein the rotating motor is fixedly arranged on one side of a tank body, a connecting rod is fixed at the connecting end of the rotating motor and thetank body, the rod end of the connecting rod is connected with the other side of the tank body through a bearing, the stirring rod is arranged on the connecting rod, an air injection hole is formed inthe rod end of the stirring rod, a ventilating film is laid on the side of the stirring rod, a feeding pipe is fixedly installed on the top of the tank body, an air outlet is reserved in the feedingpipe, the air heater is fixed on the side of the feeding pipe on the tank body, a gas delivery pipe is connected to one side of the air heater, the bottom cover is arranged at the bottom of the tank body, an observation window is embedded in the upper part of the tank body, and a convex block is fixed on the inner side of the bottom cover. According to the calcium carbonate drying device, the drying speed of calcium carbonate slurry is increased, and precipitation and agglomeration of calcium carbonate slurry are prevented.

Description

technical field [0001] The invention relates to the technical field of calcium carbonate drying, in particular to a drying device for calcium carbonate processing that prevents calcium carbonate slurry from agglomerating. Background technique [0002] Calcium carbonate is an inorganic compound, commonly known as: limestone, limestone, stone powder, marble, etc. Main components: Calcite, neutral, basically insoluble in water, soluble in hydrochloric acid; it is a common substance on the earth, found in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and also animal bones or shells The main component of calcium carbonate; calcium carbonate is an important building material, widely used in industry; calcium carbonate is formed by combining calcium ions and carbonate ions, so it is both calcium salt and carbonate. [0003] However, the existing calcium carbonate slurry is prone to mass-liquid separation during the drying process, resulting in the preci...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of drying device for calcium carbonate processing that prevents calcium carbonate slurry from agglomerating, to solve the above-mentioned background technology and propose existing calcium carbonate slurry to easily produce the mass liquid of slurry when carrying out drying process Separation, resulting in the precipitation of calcium carbonate, which makes the calcium carbonate slurry produce a large amount of lumpy accumulation during drying
