Control method of chemical reaction vessel full-automatic ice adding device

Abstract

The invention provides a control method of a chemical reaction vessel full-automatic ice adding device. The problems are solved that the temperature and the ice amount cannot be controlled precisely under manual ice adding operation, thus the quality is not uniform and the color is lowered. The method comprises the following steps: first, various set parameter values are input; second, a reaction temperature is sensed; third to fifth, whether the sensed temperature exceeds the set value is determined, ice outlet is controlled, an ice body is placed into a reaction tank finally to participate in a technology reaction after corresponding processing, weighing and conveying programs; sixth, during the ice adding process, fluctuation of the reaction temperature is monitored, and the ice adding speed and amount value are adjusted in time. The ice adding opportunity and the ice adding amount are controlled momentarily according to the moment temperature value, therefore mechanical automation temperature measurement and material adding operation are achieved by utilization of mechanical sensing control and mechanical action, precise control of the chemical reaction temperature and precise adding with ingredient proportions are raised, furthermore dye quality in batch production is uniform, and stability of excellent color of a product is ensured.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a mechanized way of ice quantity control, in particular to a control method of a fully automatic ice adding device for a chemical reaction kettle. Background technique [0002] Chemical technology refers to chemical technology or chemical production technology, which refers to the method and process of converting raw materials into products mainly through chemical reactions, including all measures to realize this transformation. The chemical production process can generally be summarized into three main steps: ① raw material processing; ② chemical reaction; ③ product refining. Among them, chemical reaction is a key step in production. The pretreated raw materials are reacted under certain conditions such as temperature and pressure to achieve the required reaction conversion and yield. The types of reactions are diverse and can be oxidation, reduction, metathesis, sulfo...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the amount of ice is manually added to the reactor, which requires a high level of experience and technology for the operators and requires a lot of human resources

In actual operation, the reaction temperature cannot be accurately controlled, and the amount of ice added and the shape of the ice body cannot be accurately controlled, resulting in different characteristics such as color, concentration, brightness, and coloring degree of each pot of product. Therefore, it is difficult to achieve a uniform quality of the product, and ultimately it is difficult to maintain the high quality of the product, reduce the value of the product, and bring about the loss of economic benefits
