Full-automatic flotation reagent quantitative adding system

Abstract

The invention provides a full-automatic flotation reagent quantitative adding system for coal slime. The reagent quantitative adding system comprises a liquid level detector, a pressure release valve, a metering pump, a safety circuit, an electromagnetic flow meter, a dustproof negative-pressure discharge hopper and a programmable controller. The safety circuit is controlled by an electromagnetic valve, and the programmable controller can process and control feedback signals. The full-automatic flotation reagent quantitative adding system has the advantages that reagent quantities can be accurately and stably controlled, reagent deficiency can be prevented, and partition and return effects can be realized for downstream unpredictable sudden accidents; the metering pump capable of accurately adjusting the output quantities and the electromagnetic flow meter capable of accurately measuring flow are introduced into the flotation reagent quantitative adding system, so that the problem of failure of an existing metering pump due to negative pressure of pipelines can be effectively solved, automatic reagent adding, liquid level detection and warning effects can be realized for a reagent bucket, and the full-automatic flotation reagent quantitative adding system is provided with the safety circuit; components of the integral system can stably run and can be automatically controlled, so that the labor intensity of operators can be reduced to the greatest extent.

Description

technical field [0001] The application relates to the field of flotation dosing, in particular to the field of quantitative dosing of fully automatic coal slime flotation. Background technique [0002] Flotation, the abbreviation of floating beneficiation, is a method of sorting according to the difference in the physical and chemical properties of the surface of mineral particles and the difference in the floatability of minerals. [0003] In the process of flotation beneficiation, in order to effectively separate useful minerals and gangue minerals, or to separate various useful minerals, it is often necessary to add certain agents to change the physical and chemical properties of the mineral surface and the properties of the medium. [0004] These agents are collectively referred to as flotation agents. [0005] Manual dispensing is difficult to accurately control, and it is time-consuming and labor-intensive, especially when several medicines are needed at the same time...

AI Technical Summary

Problems solved by technology

[0005] Manual dispensing is difficult to accurately control, and it is time-consuming and labor-intensive, especially when several medicines are needed at the same time, it requires a lot of manpower and a heavy workload

Moreover, manual dispensing is restricted by workers' sense of responsibility, technical experience, proficiency, etc. First, it is impossible to dispense medicines accurately, and second, it is impossible to dispense medicines on time. Drug shortages and outages occur from time to time, which has a great impact on production.
