A high-efficiency tangentially diverted inflow stabilization device for a center-driven thickener

Abstract

The invention discloses a high-efficiency tangentially diverted and stabilized flow device for a central drive concentrator, comprising a tangential feeder, a barrel body, a conical distributor, a diversion plate, a cloth rack, a baffle, a servo motor and a generator , the barrel is electrically connected to one end of the tangential feeder, and a drain plate is installed inside one end of the tangential feeder; in the present invention, the slurry enters the barrel through the tangential feeder, and passes through the drain plate The guiding function makes the slurry move tangentially along the inner wall of the outer block seat of the barrel, and gradually slow down through several baffles in turn, and then flow to the conical distributor through the discharge port and the arc-shaped gap after the speed is reduced , the slurry is evenly distributed, and enters the thickening tank. The central drive thickener efficiently tangentially diverts the incoming material and stabilizes the flow device, which can effectively mix the material, and through the cone distributor, it can disperse the material to achieve the best effect, so that in Under the premise of not affecting the deposition effect, the purpose of increasing the underflow concentration of the central drive thickener is achieved.

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.
