Efficient mixing reaction kettle for chemical production

Abstract

The invention provides an efficient mixing reaction kettle for chemical production, which comprises a kettle body, a grinding mechanism arranged at the top of the kettle body and an air supply mechanism arranged at the bottom of the grinding mechanism. Solid raw materials are ground into powder through the grinding mechanism and fall down, the solid raw materials are blown through the air supply mechanism when falling down, the powdery solid raw materials swing along with air, finally, the solid raw materials fall into liquid raw materials in a multi-drop-point mode, and the solid raw materials can be effectively prevented from being accumulated; meanwhile, the powdery solid raw materials can increase the contact area between the raw materials and the liquid, the mixing speed of the solid raw materials and the liquid is increased, the liquid at the bottom of the kettle body is pumped out and atomized through the liquid pumping and atomizing mechanism and then falls back, the mixed raw materials can be effectively turned over, and mixing of the raw materials is accelerated; meanwhile, floating powdery chemical raw materials can be driven to sink, so that solid raw materials can quickly fall into liquid raw materials, and the powdery chemical raw materials can be effectively prevented from flowing out of the kettle body.

Description

technical field [0001] The invention relates to the technical field of reaction kettles, in particular to a high-efficiency mixing reaction kettle for chemical production. Background technique [0002] The broad understanding of the reaction kettle 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 are realized. The reaction kettle is widely used in petroleum, chemical, In the fields of rubber, pesticides, dyes, medicine and food, it is a pressure vessel used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; material Generally, there are carbon-manganese steel, stainless steel, zirconium, nickel-based alloys and other composite materials.

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following deficiencies: Most of the reaction kettles used for chemical production in the prior art directly add solid chemical raw materials into the reactor. Since the solid chemical raw materials are mostly piled up in one area when they enter the reactor, they need to be dissolved layer by layer when they are dissolved. Dissolution, and some solid chemical raw materials have large particles, and the total contact area with the liquid is small, and it takes a long time to dissolve, resulting in a greatly reduced mixing rate of raw materials. Secondly, because most of the chemical raw materials in the reactor are mixed. Horizontal agitation, the agitation effect is poor, and some solid chemical raw materials are easy to settle at the bottom of the reactor, which further reduces the mixing rate of raw materials
