Description

Temperature-controlled reaction kettle capable of efficiently stirring

Technical Field

The invention belongs to the technical field of chemical equipment, and particularly relates to a temperature-controlled reaction kettle capable of efficiently stirring.

Background

The high-speed grinding disperser adopts a high-speed stirrer (such as a circular saw-tooth stirrer) to form strong turbulence locally, and generally has strong dispersing and emulsifying effects on materials. The powerful centrifugal force of high-speed grinding dispersion machine throws the material radially into between the stator, the narrow accurate clearance of rotor, receives comprehensive effort such as centrifugal extrusion, liquid layer friction, hydraulic impact simultaneously, and the material is by preliminary dispersion. The high-speed rotating rotor of the dispersion machine generates a linear velocity of at least 15m/s, and the materials are dispersed and crushed under the action of strong hydraulic shearing, liquid layer friction, tearing collision and the like and are simultaneously ejected through the stator slot at a high speed. The material of the dispersion machine is continuously ejected from the radial direction at high speed, the flow direction is changed under the resistance of the material and the wall of the container, and meanwhile, an upper and a lower strong turning turbulence flows are formed under the action of an upper and a lower axial suction forces generated in a rotor area. The material is circulated for several times to finally complete the dispersion process.

Because the rotor of high-speed grinding dispenser has high rotational speed to and the narrow precision in clearance between the rotor, consequently the material need carry out abundant stirring and rough machining before getting into the high-speed grinding dispenser, in order to guarantee that the material that gets into the high-speed grinding dispenser is abundant even, and does not have the impurity or the granule of major diameter.

To above-mentioned demand, current technique often sets up reation kettle at the material entrance of high-speed grinding dispenser, put into reation kettle with the material ratio as required earlier and carry out intensive mixing and reaction in, and in order to improve industrial production's efficiency, reation kettle's volume is often great, make the stirring efficiency of material in the reation kettle lower, and stir or take place the reaction to material in the reation kettle, can produce endothermic reaction or exothermic reaction, consequently, the reation kettle outer wall often is provided with heat preservation device, and under the too big condition of reation kettle volume, heat preservation device is difficult to guarantee the even of temperature in the reation kettle equally, thereby influence the efficiency of material stirring or reaction, lead to the material to become nature under high temperature even.
