Dispersion device for triaxial viscous slurry

Abstract

The invention relates to a three-shaft scattering device of viscous slurry. The three-shaft scattering device comprises a round cylinder, a master stirring apparatus, a slave stirring apparatus, a guide blade, a pressure stabilizing plate, a waveform shear plate, a feeding hole, a discharge hole, a round hole sieve plate, a high-pressure water pipe and the like. According to the scattering device of the viscous slurry, the pressure stabilizing plate is arranged at the bottom and can automatically suck ore slurry into the round cylinder by pressure difference; a cylindrical rotary zone in the cylinder is eliminated by the shear plate arranged at the inner wall; the shear performance of the material is also improved; the stirring intensity of each stirring apparatus is effectively increased by the guide plate and three groups of mixing impellers arranged on stirring bearings; namely, the kinematic velocity of the material in the round cylinder is increased. Thus, effective dispersing of a viscous material is achieved.

Description

Technical field: [0001] The invention relates to a material stirring and breaking up device, in particular to a breaking up and stirring device for viscous materials which have undergone flocculation treatment. Background technique: [0002] The iron and steel industry needs to consume a lot of resources and energy in the production process, and also produces a lot of solid waste, and gas mud is one of them. The gas sludge is the product obtained by filtration and dehydration after wet dedusting. During the filtration process, a large amount of polyacrylamide needs to be added as a flocculant. Dispersion will directly affect subsequent sorting operations. The existing technology mostly adopts the method of grinding, and although this technology solves the problem of inter-flocculation of fine particles to a certain extent, the cost of processing such raw materials increases due to the high energy consumption generated by grinding. The resulting particles are over-grinded, ...

AI Technical Summary

Problems solved by technology

Due to the fine particle size and high viscosity of the gas mud, if the blade is short, the slurry cannot be effectively dispersed, and the agent cannot fully contact the ore particles.

Aiming at the problem that the conventional stirring device cannot flocculate the fine particles seriously in the actual separation process, and various useful minerals are difficult to separate, a flocculation-treated viscous slurry dispersing device is designed.
