Automated feeding device for chemical liquid atomization and feeding method of automated feeding device

Abstract

The invention discloses an automated feeding device for chemical liquid atomization and a feeding method of the automated feeding device and relates to feeding devices and methods of acidic / basic chemical liquid. The automated feeding device comprises a chemical liquid storage tank, a reaction vessel and a control device, wherein a chemical liquid conveying pipeline is arranged between the bottomof the chemical liquid storage tank and the top of the reaction vessel and is provided with a feeding pneumatic valve, a flow detecting device and a supercharging pump, the flow detecting device is incontrol connection with the feeding pneumatic valve and a hot water pneumatic valve separately, the hot water pneumatic valve is arranged between the feeding pneumatic valve and the supercharging pump and communicates with a hot water pipeline, an atomizer is arranged at the internal top of the reaction vessel, a refluxing pipeline is arranged at the top of the chemical liquid storage tank, and apressure relief refluxing pneumatic valve and a hydraulic detecting device are arranged on the refluxing pipeline. The automated feeding device and the feeding method have the advantages that the feeding is quantitative and automatic, the service life of equipment is prolonged, pipeline blocking is reduced, pipeline burst is prevented, the feeding is uniform, the structure is simple, the operation is convenient, labor is saved, the control is accurate and timely, the efficiency of reaction and purification is increased, and the like.

Description

technical field [0001] The invention relates to a chemical equipment and a control method, in particular to an acid-base chemical liquid feeding device and a feeding method thereof. Background technique [0002] At present, in the chemical industry, especially in the process of metallurgical wet separation and purification, the addition of chemical liquids such as acid and alkali to the ore pulp is fed by high-level waste, and sometimes the local concentration in the reaction process is too high due to uneven feeding. As a result, impurities and target particles are leached or precipitated together so that the expected separation effect cannot be achieved, and the rework process is complicated and wastes a lot of manpower and material resources. At the same time, the input-output efficiency and purification efficiency are affected, and the production cost is increased. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the...
