A reaction device for printing and dyeing chemical industry

Abstract

The invention relates to a reaction device for a printing and dyeing chemical industry. The reaction device comprises a tank body, a tank cover, a gas heating device, and a plurality of escape pipes inserted into the tank body from the bottom, wherein the escape pipes are connected with the exhaust end of the gas heating device; an exhaust plate is arranged at the end part of each escape pipe, inserted into the tank body; an electric heating tube fixed inside the tank body is arranged below an agitator blade above the exhaust plate. On one hand, the escape pipes are communicated to the bottom of the tank body of the reaction device, the heated inert gases are conveyed to the inside of the tank body by using the escape pipes, and hot gases are dispersed through a diffuser plate, so that the heat can be quickly transferred to the material inside the tank body to heat the material; on the other hand, the electric heating tube arranged inside the tank body can directly heat the material, and the material generates convection due to the characteristic that the gases input by the escape pipes quickly move upwards, so that the heat of the electric heating tube is more quickly and more uniformly transferred to the material.

Description

technical field [0001] The invention relates to a chemical reaction device, in particular to a chemical reaction device for printing and dyeing. Background technique [0002] At present, most of the reaction devices used to prepare printing and dyeing auxiliaries on the market are not equipped with a stirring device, which makes the materials in the reaction insufficiently and unevenly stirred, which directly leads to slow reaction speed and incomplete reaction, wasting resources and improving production. cost, and some reaction medium remaining in the tank after the reaction is easy to corrode, which affects the reaction equipment and cannot improve economic benefits. [0003] In order to solve the above problems, Chinese utility model patent CN203123964U discloses a reaction device for preparing printing and dyeing auxiliaries, which is equipped with a stirring shaft extending into the tank body on the tank cover, and an anchor paddle is installed at the bottom of the stir...

AI Technical Summary

Problems solved by technology

[0004] However, the preparation of some printing and dyeing auxiliaries requires a certain heating environment. Traditionally, the heating of the material can only be achieved by heating the tank body. The heating speed is slow and the temperature of the material in the tank is not uniform, which is not conducive to the smooth progress of the reaction.
