Small automatic acid preparation device and acid preparation method

Abstract

The invention discloses a small automatic acid preparation device and an acid preparation method. The device comprises a substrate, a PLC and a plurality of acid preparation units, wherein the PLC isconnected with all the acid preparation units; each acid preparation unit comprises a conveying mechanism, a liquid suction mechanism and a weighing mechanism; the conveying mechanisms are used for conveying liquid containing bottles containing raw acid into the device and conveying empty liquid containing bottles out of the device; the liquid suction mechanisms are used for taking the raw acid out of the liquid containing bottles through a jet flow technology and feeding the raw acid into acid preparation barrels of the weighing mechanisms; the weighing mechanisms are used for detecting the mass of the acid preparation barrels and controlling the water adding amount. The liquid suction mechanisms of the device utilize the jet flow technology to realize acid taking and raw acid atomization; existing liquid-liquid acid preparation is converted into liquid-mist acid preparation, transfer of raw acid is achieved, the raw acid is atomized into small liquid drops, the specific surface areais increased, the raw acid makes more sufficient contact with acid liquid or water, the heat dissipation effect and the heat dissipation efficiency during dilution are greatly improved, and the heat dissipation problem during current acid preparation is ingeniously solved.

Description

technical field [0001] The invention relates to the field of acid solution configuration, in particular to a small automatic acid preparation device and an acid preparation method. Background technique [0002] At present, various concentrations of acids, including sulfuric acid, hydrochloric acid, and formic acid, are used in various manufacturing industries such as chemical industry, medicine, and textiles. Because the concentration requirements of acid solutions in various industries are different, most of the acid solutions used are prepared by diluting concentrated acid. In the process of acid preparation, concentrated acid will release a large amount of heat when it is diluted. How to solve the heat dissipation problem is a very important problem. big security risk. [0003] The current way of diluting the acid solution is to manually add pure water into the acid mixing tank first, and then add the original acid for stirring. There are great dangers in artificially ...

Problems solved by technology

There are great dangers in artificially diluting the acid solution, such as the corrosion of the original acid in contact with the skin, the inhalation hazard of the volatilization of the acid solution, the large amount of heat release when the original acid is mixed with water, etc. harm

At present, many automatic acid dispensing devices are designed for the large demand of industrial acid. For the laboratory level with small demand, not only the acid adding process is complicated, the equipment occupies a large area, but also it is easy to cause waste of resources.
