Refining agent reaction device

Abstract

The invention relates to a refining agent reaction device. The device comprises a tank body and a tank cover, wherein a round hole is formed at the center of the tank cover, a support is fixed above the round hole, the support is internally provided with a sealing spherical bearing, the sphere of the sealing spherical bearing is connected with a stirring shaft, the bearing box of the sealing spherical bearing and the support are fixed together, a flexible sealing membrane is fixed between the round hole and the sphere, a sealing cavity is formed between the flexible sealing membrane and the support, and pure water fills in the sealing cavity. According to the reaction device, by the spherical bearing, a mixing propeller can stir in all directions without dead corners; due to the adoption of the flexible sealing membrane for sealing, gas in an internal tank does not leak, so that operators are effectively protected and the environment is not polluted; as the sealing cavity above the sealing membrane is filled with water, and when pressure in the tank changes, the sealing cavity can well support the sealing membrane, the sealing membrane does not plump up or cave in, does not bear extra tension, cannot be broken easily, and has a long service life.

Description

technical field [0001] The invention relates to a refining agent reaction device. 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 CN 203123964 U 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 is installed at the bottom of the stirring shaft Shaped paddles realize the stirring of materials and spe...

AI Technical Summary

Problems solved by technology

[0004] However, some printing and dyeing auxiliaries have harmful substances volatilized during the preparation process, so they need to be stirred in a closed environment

Traditional stirring reaction devices mostly use packing seals or mechanical seals. The packing seal has poor sealing performance, large resistance, and is easy to wear out; while the mechanical seal is expensive, and the sealing performance decreases after a period of use, and the maintenance and replacement costs are high.

[0005] In addition, sometimes the reaction requires a certain heating environment. Traditionally, the material can only be heated by heating the tank. 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.
