a reaction kettle

Abstract

The invention discloses a reaction kettle, which comprises a kettle body, a magnet, a stirring shaft, a plurality of stirring rods and a multi-turn closed coil; the magnet is fixed on the upper and lower parts of the kettle body; the stirring shaft is arranged in the kettle body and passing through the magnet vertically; the stirring rod is fixed on the radially extending end of the stirring shaft and sandwiched between the magnets; the multi-turn closed coil is fixed on the horizontally adjacent stirring rod, And the closed coil cuts the magnetic induction line of the magnet as the stirring rod rotates in the horizontal direction. Compared with the prior art, the present invention, based on the principle of electromagnetic induction, makes the closed coil ring in the kettle body perform cutting magnetic induction movement, and then generates an induced current, thereby heating the closed coil ring, so that the heating function can be realized without additional supply of electric energy , greatly saving energy.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a reaction kettle. Background technique [0002] As a container for hydrolysis, heating and stirring reactants, the reaction kettle is widely used in the research of chemical, pharmaceutical, food and other production and scientific research projects. Existing reactors generally include a kettle body, a stirring shaft, a motor, stirring blades and heating pipes. The stirring shaft is arranged in the kettle body and rotates under the drive of the motor. The stirring blade is fixed on the stirring shaft and rotates with the stirring shaft. The heating tube is arranged on the bottom or both sides of the kettle body to realize the reaction of the kettle body Heating of things. However, if the heating pipe is arranged on the bottom or both sides of the kettle body, there will be a problem of uneven temperature in each area of ​​the kettle body, especially the upper part of the kettle body wil...

AI Technical Summary

Problems solved by technology

However, if the heating pipe is arranged on the bottom or both sides of the kettle body, there will be a problem of uneven temperature in each area of ​​the kettle body, especially the upper part of the kettle body will not be heated to form a low temperature zone.

At this time, in order to ensure the reaction efficiency, the only way to increase the power of the heating tube is to increase the temperature of the heating tube, and the increase in the temperature of the heating tube will easily cause the temperature of the local reactants to be too high, resulting in the problem of coking of the product

And the heating tube needs to be continuously energized to achieve the purpose of heating, and the continuous energization will consume a lot of energy
