Reaction kettle

Abstract

The invention relates to a reaction kettle which comprises a reaction kettle shell, a feeding opening and a discharging opening, wherein the feeding opening is formed in one side of the upper end of the reaction kettle shell; the discharging opening is formed in the lower end of the reaction kettle shell; a stirring shaft is arranged in the reaction kettle shell, stirring blades are symmetrically arranged on the stirring shaft, the stirring shaft penetrates through the reaction kettle shell and is connected with a motor, a plurality of circles of hot water pipes are wound outside the reaction kettle shell from top to bottom, the upper end of the hot water pipe is connected with a water inlet pipe, the lower end of the hot water pipe is connected with a water outlet pipe, the water outlet pipe is communicated with the water inlet pipe through a water return pipe, a water storage tank is arranged on the water return pipe, and a heating pipe is arranged outside the water storage tank. The reaction kettle provided by the invention has the advantages that hot water moves in the hot water pipe in a surrounding manner, so that the hot water pipe uniformly transfers heat into the reaction kettle shell from top to bottom; the hot water surrounding for one circle can be re-utilized through the water outlet pipe via the water return pipe; the water storage tank and the heating pipe work together to re-heat returned water.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a reaction kettle. Background technique [0002] The reaction kettle is a kind of reaction equipment commonly used in chemical plants. It mainly uses a motor to drive the stirring shaft to stir the reactants so that they can fully react to obtain the required substances. With the continuous development of the chemical industry, people have higher requirements for the finished products of chemical products and the precision of chemical products. Correspondingly, people have also put forward higher requirements for the reactor, an important equipment in chemical reactions. At present, the commonly used reactors are heated to achieve constant temperature and heat preservation for a long time. After the existing reactors are reacted, the reactors will still have a relatively high temperature. The current treatment methods are basically to let them cool directly without using them. ...
