Efficient tangential drainage feeding flow stabilizing device of central transmission thickener

Abstract

The invention discloses an efficient tangential drainage feeding flow stabilizing device of a central transmission thickener, which comprises a tangential feeder, a bucket body, a conical distributor,a drainage plate, a distribution frame, a baffle, a servo motor and a generator; the bucket body is communicated with one end of the tangential feeder, and the inner side of one end of the tangentialfeeder is provided with the drainage plate; according to the invention, slurry passes through the tangential feeder and enters the bucket body, so that by means of the guide effect of the drainage plate, the slurry moves in the tangential direction and tangentially moves along the inner wall of the outer stop seat of the bucket body, so that the speed is gradually reduced through a plurality of baffles in sequence; after speed reduction, the materials flow to the conical distributor through the discharge port and the arc-shaped notch; slurry is uniformly distributed and enters the concentration tank and the central transmission thickener to be efficiently and tangentially guided into the feeding and flow stabilizing device; therefore, the materials can be effectively mixed and are dispersed and fed through the conical distributor to achieve the optimal effect, so that the purpose of improving the underflow concentration of the central transmission thickener is achieved on the premisethat the deposition effect is not affected.

Description

technical field [0001] The invention relates to the field of industrial slurry processing equipment, in particular to a high-efficiency tangentially diverted inflow stabilizing device for a central drive thickener. Background technique [0002] The central drive thickener is mainly suitable for the solid-liquid separation of industrial slurry. It is widely used in metallurgy, mining, coal, chemical, building materials and environmental protection departments for the treatment of ore sludge, waste water and waste residue, as well as water and sewage treatment, etc. Concentration and purification of solid slurry in the industry, that is, it is of great significance to improve the utilization rate of return water, the concentration of underflow transportation, and environmental protection; the thickener uses the material particles in the slurry to naturally Settling is used to complete the concentration, that is, after the slurry enters the thickening tank, the material particl...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency tangentially diverted material flow stabilization device for a central drive thickener. In order to overcome the above-mentioned slurry with different viscosities and different particle sizes entering the thickener and different feeding methods, the settlement effect is not constant. For the heavy metal slurry, it is required to feed smoothly and fully mix with the flocculant to increase the concentration of the underflow; at the same time, in the process of decelerating the tangential slurry through the baffle, it is impossible to properly decelerate the distribution of different slurries to the greatest extent. , when decelerating at the same time, the slurry impacts on the outside of the baffle, and it is easy to cause damage to the baffle after long-term use, which requires frequent replacement of the baffle.
