Liquid raw material rapid quantitative injection system and its control method

Abstract

The invention discloses a rapid and quantitative injection system of liquid raw materials and a control method of the rapid and quantitative injection system. The rapid and quantitative injection system comprises an injection pump with an injector which is obliquely arranged, wherein the injection pump is connected with an angular displacement mechanism for driving the injection pump to rotate; a hoisting mechanism is fixed at the bottom of the angular displacement mechanism; and a translation mechanism for driving the hoisting mechanism to move horizontally is fixed at the bottom of the hoisting mechanism. The rapid and quantitative injection system has the beneficial effects that the movement of each mechanism is coordinately controlled through a control system, and accurate metering and rapid injection speed are realized; the rapid and quantitative injection system is applicable to a plurality of types of liquid raw materials, and a plurality of types of injection requirements can be met; the automation degree is high and the manual operation is greatly reduced; a slide platform mechanism and the injection pump are arranged, so that the rapid and quantitative injection of the liquid raw materials is realized; and the translation mechanism, the angular displacement mechanism and the hoisting mechanism are arranged, so that the height and an inclined angle of the system can be adjusted and the system can be applicable to a plurality of types of devices.

Description

technical field [0001] The invention relates to a raw material injection system, in particular to a liquid raw material rapid quantitative injection system and a control method thereof. Background technique [0002] Fast, quantitative micro-level accurate sampling is an indispensable way and means in the basic process of in-situ analysis in experimental research. At present, the sampling technology of solid materials is relatively mature, and there are many related scientific and technical documents and patent documents. Commercially available solid powder feeding equipment is also being gradually improved and automated in function. [0003] In experimental research and industrial production, liquid raw materials generally have the characteristics of high viscosity, easy oxidation, easy moisture absorption and corrosion, and ordinary feeding equipment is difficult to meet the requirements. At present, there are only a few single-type liquid feeding systems for specific equi...

[0003] In experimental research and industrial production, liquid raw materials generally have the characteristics of high viscosity, easy oxidation, easy moisture absorption and corrosion, and ordinary feeding equipment is difficult to meet the requirements

At present, there are only a few single-type liquid feeding systems for specific equipment, such as liquid stearic acid feeding system, which has a narrow scope of application; when feeding many equipment, usually in the process of feeding and retrieving, there is a waste of raw materials The problem, and the feeding speed is slow, the efficiency is low, and the accurate feeding cannot be realized automatically
