Variable frequency control reactor

Abstract

The invention discloses a variable frequency control reactor comprising a reactor body comprising an upper portion and a lower portion. The top of the upper portion is provided with a feed opening; the bottom of the lower portion is provided with a discharge opening. The variable frequency control reactor further comprises a mixing motor and a mixing device; the mixing motor is disposed over the reactor body; the mixing device is connected with the mixing motor; the mixing motor is electrically connected with the output end of a variable frequency controller. The reactor body is further provided with a pipeline provided with a pressure sensor; the output end of the pressure sensor is electrically connected with the input end of the variable frequency controller. In the case that interior pressure of the reactor is too high, the pressure sensor generates semiconductor deforming pressure on the surface of a sheet; the sheet is deformed by the external force (pressure) to generate piezoelectric impedance, thus changes in the impedance are converted into electrical signals transmitted to the variable frequency controller. The variable frequency controller controls the speed of the motor according to a set pressure output frequency; the motor controls the mixing speed, stabilizing reaction conditions.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a reaction kettle controlled by frequency conversion. Background technique [0002] In the chemical industry, the reactor is an essential chemical machinery and equipment. In the actual operation process, due to the difference in physical properties of various materials, they will be affected by viscosity, concentration, particle size, etc. during the reaction, which will cause the materials to be stirred unevenly in the reactor, and there will be dead spots in the reactor, and the pressure in the reactor will be too high. When it is large, maintaining high-speed stirring will have a negative impact on the material reaction, resulting in a low reaction yield, and even the reaction will proceed in a direction that is not conducive to the production of products. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, ...
