Sealing reaction device

Abstract

The invention relates to a sealing reaction device. A support is fixedly arranged above a circular hole in the center of a pot cover of the sealing reaction device. A sealing spherical bearing is arranged in the support. A sphere of the sealing spherical bearing is connected with a stirring shaft. A sealing film is fixed between the circular hole and the sphere. A sealing cavity is formed between the sealing film and the support, and water is injected into the sealing cavity. The sealing reaction device further comprises a gas heating device, a gas inlet pipe inserted from the bottom and a water circulation system with the auxiliary heating function. Due to the fact that water is injected into the sealing cavity above the sealing film, when pressure in a pot is changed, the sealing cavity can play a good supporting role for the sealing film, the sealing film will not plump up or collapse so as not to be subjected to additional tension, thereby not being easy to damage, and the service life is longer. Due to the rapid upward movement characteristic of gas input by the gas inlet pipe and the water circulation system with the auxiliary heating function, convection can be produced for materials, and heat of an electric heating pipe can be more rapidly and evenly transferred to the materials.

Description

technical field [0001] The invention relates to a sealed reaction device. Background technique [0002] At present, most of the sealed 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 efficiency. Production cost, and some reaction mediums remaining in the tank after the reaction are easy to corrode, which affects the reaction equipment and cannot improve economic benefits. [0003] In order to solve the above problems, the Chinese utility model patent CN203123964U discloses a sealed 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 shaped shaft is installed at the bottom end of the stirring shaft The pad...

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 sealing reaction devices with agitation 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 cost of maintenance and replacement is 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.
