Chemical synthesis reaction kettle with shaft-free stirring function

Abstract

The invention discloses a chemical synthesis reaction kettle with shaft-free stirring function. The chemical synthesis reaction kettle with shaft-free stirring function can avoid the disadvantages ofa central shaft driving an agitator through a shaftless stirring device, and has the characteristics of adjustable rotation speed, and solves the problem of leakage of machine seal of the reaction kettle. A diversion plate strip is arranged on the inner wall of a kettle body, and can reduce material swirling, force a material to produce radial motion and improve the mixing effect. In addition, thetemperature, pressure and liquid level of the material inside the reaction kettle body can be transmitted to a controller through a temperature sensor, a pressure sensor and a liquid level sensor, and then the information is displayed on a display screen, and parameters are set and adjusted through the display screen. The setting of the liquid level sensor can effectively avoid the situation thatthe liquid level is too high. When the pressure inside the kettle body exceeds a set value, the controller controls the pressure relief valve to adjust the air pressure in the kettle body, and when the air pressure is too high and exceeds the set value, the air pressure jacks the pressure relief valve, thus the air pressure in the kettle body is reduced in time and safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of chemical raw material mixing auxiliary devices, in particular to a shaftless stirring chemical synthesis reaction kettle. Background technique [0002] With the continuous advancement of science and technology, the substances needed in the chemical and pharmaceutical industries need to be produced in the reactor. In order to promote the reaction speed and effect in the reactor during the reaction of the items in the ordinary reactor, the existing The reaction kettle is generally equipped with a special stirring shaft at the center axis of the tank body, and the upper end is connected with the motor assembly arranged at the top of the tank body. However, during the operation of the reactor, the internal stirring of the reactor is uneven, and it is difficult to ensure that the inner cavity material It can fully react, and the material bonded to the inner wall cannot be directly scraped off during the treatm...

AI Technical Summary

Problems solved by technology

The way that the central shaft drives the agitator causes all the resistance of the agitating blades to be concentrated on the agitating shaft. The design requirements for the strength of the agitating shaft are too high, which limits the diameter of the agitating blades.
