Reaction kettle for foaming

Abstract

The invention relates to a reaction kettle for foaming. The reaction kettle comprises a reaction kettle body, a stirring transmission mechanism arranged on the reaction kettle body and a ventilation stirring paddle mounted on the stirring transmission mechanism. The reaction kettle body comprises a kettle body and a kettle cover fixedly mounted at the top end of the kettle body. The stirring transmission mechanism comprises a stirring motor fixedly mounted at the top of the kettle cover, a hollow rotating shaft vertically and rotationally mounted in the middle of the kettle cover, and a driving shaft vertically and rotationally mounted in the center of the reaction kettle body. The ventilation stirring paddle comprises a stirring shaft and three stirring blades which are uniformly distributed relative to the central axis of the stirring shaft. According to the reaction kettle disclosed by the invention, the mixing reaction of a foaming mixture is quicker and more uniform, and the multi-stage ventilation structure integrally designed with the stirring structure enables the foaming material finally discharged from the reaction kettle body to have the structural characteristic of moreuniform density.

Description

Technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a reaction kettle for foaming. Background technique [0002] The broad understanding of the reactor is the container with physical or chemical reaction. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be realized. Generally, it is made of carbon-manganese steel, stainless steel, and zirconium. , Nickel-based (Hastelloy, Monel, Inconel) alloy and other composite materials. The reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other industries. It is a pressure vessel used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes. [0003] The foaming reactor is a kind of mixing reaction vessel used to generate foam. For example, the foaming reactor is used for poly...

AI Technical Summary

Problems solved by technology

[0003] A foaming reactor is a mixing reaction vessel used to generate a foam. For example, a foaming reactor is used for polyurethane foaming to generate a foamed foam with closed cells, but generally existing The stirring structure of the foaming reactor is fixed at a certain height. During the mixing and stirring process, only the foaming composite material in a certain space area can be stirred. In order to achieve full and uniform mixing and stirring, it is necessary to ensure a long time Stirring time, low efficiency and high power consumption. In addition, stirring and aeration are generally carried out separately, so that the gas introduced cannot be better mixed with the mixed material during the stirring process, and aeration and agitation cannot be achieved. Forms an adequate fit and is therefore less effective at promoting the formation of a homogeneously structured foam
