Problems solved by technology

[0002] At present, most of the underflow natural discharge systems of thickeners adopt open discharge, that is, through an intermediate tank, the underflow is discharged to the intermediate tank, and then transported by a pump. This transportation method is very prone to volume imbalance during use and causes intermediate discharge. The phenomenon of overflowing liquid in the tank, this transportation method requires the operator to stick to the site, start and stop the equipment and adjust the opening of the valve on site to maintain the volume balance of the intermediate tank, which is complicated to use and labor-intensive
Even if the underflow discharge device of some thickeners is transported by a closed pipeline, it is very prone to pipeline blockage, the pump body freezes, the motor burns out, and maintenance and cleaning are difficult. Once the pipeline is blocked, it needs to be dismantled and cleaned one by one. Large and expensive to repair

Abstract

The invention belongs to the technical field of chemical industry, smelting industry and coal industry, and particularly relates to a novel underflow anti-clogging discharge method and a novel underflow anti-clogging discharge device, which are created and modified on the basis of a conventional thickener underflow discharge system, for a thickener. In order to solve the current situation that potential safety and environment-friendly hazards such as pipeline clogging, pump body coagulation, underflow overflow and the like are liable to occur in a natural underflow discharge process of the thickener, and the maintenance cost is high, the invention provides a safe, environment-friendly and efficient underflow anti-clogging discharge method and underflow anti-clogging discharge device for the thickener. The novel underflow anti-clogging discharge method and the novel underflow anti-clogging discharge device have the characteristics of being anti-clogging, safe, environment-friendly, convenient and time-saving to repair and maintain, capable of reducing the maintenance cost, stable in underflow discharge, and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, smelting, coal and other industries, and is an underflow anti-clogging discharge method and device for a thickener which is innovated and improved on the basis of the underflow discharge system of a traditional thickener. Background technique [0002] At present, most of the underflow natural discharge systems of thickeners adopt open discharge, that is, through an intermediate tank, the underflow is discharged to the intermediate tank, and then transported by a pump. This transportation method is very prone to volume imbalance during use and causes intermediate discharge. The phenomenon of overflowing liquid in the tank, this transportation method requires the on-site operators to stick to it, start and stop the equipment on site and adjust the opening of the valve to maintain the volume balance of the middle tank, which is complicated to use and labor-intensive. Even if the underflow ...
