Deep cone thickener with scraper device

Abstract

The invention provides a deep cone thickener with a scraper device, which comprises a tank body and supporting legs arranged at the lower part of the outer side of the tank body, and is characterized in that a supporting platform is welded on the upper surface of the tank body, a driving mechanism is arranged in the center of the upper surface of the supporting platform, the lower end of the driving mechanism is in transmission connection with a vertical shaft, the lower end of the vertical shaft penetrates through a connecting plate to be connected with a supporting plate, and scraping plates are arranged at the two ends of the connecting plate. A flow stabilizing barrel is fixed to the lower surface of the supporting platform and located on the outer side of the vertical shaft in a surrounding mode, and one side of the flow stabilizing barrel is connected with a liquid inlet pipeline. An overflow weir is arranged on the periphery of the upper surface of the tank body and located below the supporting platform. During working, coal slurry on the inner wall of the tank body can be pushed downwards to the coal slurry outlet to be discharged, hardening and blocking are prevented, meanwhile, clarified water can enter a clean water tank in a process flow from a clean water outlet in the overflow weir, and water resources can be recycled.

Description

technical field [0001] The invention belongs to the technical field of deep cone thickeners, in particular to a deep cone thickener with a scraper device. Background technique [0002] In the coal washing industry, coal washing with jigging method is a commonly used coal preparation process. The water used for jigging coal preparation is used as the washing medium. In order to save precious water resources, a closed-circuit washing water is usually used, that is, the slime water is For concentration treatment, a deep cone thickener is usually used for precipitation treatment. The deep cone thickener is a body with a cylindrical upper part and a conical lower part. In the conical concentration tank, under the action of gravity and flocculant, the tailings particles in the coal slurry water sink and gather downward along the cone wall. A mud pump is installed at the bottom of the cone, and the pump is pumped into the filter press for further concentration, so that the coal Sl...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a deep cone thickener with a scraper device to solve the problem that the existing deep cone thickeners usually suffer from silting and compaction and blockage of the mud pump due to different working conditions and shift maintenance operations. The suction pipeline stops the entire production line, affecting the normal operation of the entire coal washing production line, and the water resources carried in the sewage cannot be effectively utilized
