Reaction kettle convenient for layered disassembling of filter screens

Abstract

The invention relates to the field of reaction kettles, and concretely relates to a reaction kettle convenient for layered disassembling of filter screens. The reaction kettle comprises a reaction kettle body, an auxiliary structure, a stirring structure, a mixing structure and a filtering structure. The mixing structure runs while polymer polyol raw material and a catalyst are stirred through thestirring structure, so the polymer polyol raw material and the catalyst are uniformly mixed gradually, and fall into the reaction kettle body from the mixing structure, thereby the stirring structureruns easily; gradual stirring of the polymer polyol raw material and the catalyst facilitates a mixing reaction of the polymer polyol raw material and the catalyst; the filtering structure is pushedwhile the polymer polyol raw material and the catalyst are stirred through the stirring structure, so the polymer polyol raw material and the catalyst are fully reacted in a layering manner; and blockage is avoided in the shaking process of the filtering structure, and a gas can penetrate through the filtering structure and is discharged, so decompression of the internal of the reaction kettle body prevents the reaction kettle body from being damaged.

Description

technical field [0001] The invention relates to the field of reaction kettles, in particular to a reaction kettle which is convenient for layering and disassembling filter screens. Background technique [0002] The reactor is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The reactor is widely used in petroleum, chemical, rubber, Pesticides, dyes, medicines, food, pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; materials generally include carbon-manganese steel , stainless steel, zirconium, nickel-based alloys and other composite materials.

AI Technical Summary

Problems solved by technology

[0003] However, when the traditional polymer polyol is prepared inside the reactor, there are particle differences in the polymer polyol raw material, so that the polymer polyol raw material and the catalyst cannot be well mixed to produce polymer polyol, which affects the production of polymer polyol Efficiency, when the polymer polyol and the catalyst are mixed together and added to the reactor, the polymer polyol raw material and the catalyst will react before they are all added to the reactor, resulting in the leakage of the gas after the reaction, which will cause harm and is not conducive to the polymer. Production of polyols
