Reaction kettle for producing building coatings

Abstract

The invention relates to the technical field of reaction kettles, and discloses a reaction kettle for producing building coatings, which comprises a kettle body, a sealing cover is arranged above thekettle body, a servo motor is arranged above the sealing cover, and the right side of the servo motor is fixedly connected with the lower part of the sealing cover. According to the reaction kettle for producing the building coatings, cleaning devices, an adhesion device and a driven wheel are matched, the adhesion device is in a double-cross transmission connection with the driven wheel and the cleaning devices on the two sides of the driven wheel, and a conical separation body is used for cleaning. dust and splashed acid impurities adsorbed on the outer surface of the driven wheel can be thoroughly adsorbed and cleaned conveniently, meanwhile, adsorbed acid substances are collected in a containing vessel, damage of the the impurities to the joint of a transmission rod and the driven wheel is effectively avoided, and the transmission rod and the driven wheel are protected. Meanwhile, the controllability of a product generated when the reaction kettle works is guaranteed.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a reactor used for producing architectural coatings. Background technique [0002] Reactor is a kind of reaction device used to carry out the structure design and parameter configuration of the container according to the process conditions of different reactants. It has corresponding parameter configuration technical standards, so as to facilitate the realization of the heating, evaporation, cooling and The function of mixing and configuring the reaction, the stirring in the middle layer and above the inner cavity of the reactor produces axial flow, the stirring in the lower layer produces radial flow, and forms a cyclically changing flow under the action of the front cavity in the reactor, so that the internal reactants Or react with gas. [0003] When the chemical reaction is carried out in the inner cavity of the existing reaction kettle, when the acidic impurities generated...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a reaction kettle for producing architectural coatings, which has the function of anti-corrosion protection for the junction of the transmission rod and the driven wheel, and at the same time ensures the controllability of the products produced when the reaction kettle is working and improves the passing through of the reaction kettle. The advantage of the sealing effect of the oil seal solves the problem that when the chemical reaction is carried out in the inner cavity of the existing reactor, when the acidic impurities generated during the reaction splash into the inner cavity of the stirring rod and the ring sleeve, the inner cavity of the stirring rod is caused The plasticity and strength of the ring sleeve itself are reduced, resulting in cracking or delayed brittle failure. When the internal conditions of the reactor are high temperature or high pressure, hydrogen will infiltrate into the inner cavity of the corresponding stirring rod in an atomic state. The interior between the ring and the metal is combined into molecules to generate high pressure. In severe cases, it will cause the surface to bulge or wrinkle, resulting in white spots, that is, hydrogen embrittlement, which is harmful to the stirring rod and the ring. If it is damaged, it is usually neutralized by adding alkaline substances such as sodium carbonate, which not only increases the cost and difficulty of handling each response, but also is not conducive to controlling the quality of alkaline substances required for neutralization. The reaction process will be accompanied by heat changes, which will affect the temperature of the reactants inside the reactor, resulting in deviations in production; however, water washing is generally carried out before the reaction, so that the acidic substances that appear during the reaction cannot be cleaned in time; and now In order to avoid mechanical wear between connecting parts, some reactors generally use oil seals for sealing. However, when the oil is left standing for a long time, the colonies and internal impurities tend to make the oil ring tilt and easily cause oil passages. Blockage occurs, which affects the sealing effect
