Description

Technical Field

[0001] The utility model relates to the field of chemical industry, in particular to an anhydrous piperazine fast dissolving device. Background Art

[0002] Anhydrous piperazine is a commonly used chemical substance with wide applications in medicine, chemical industry, etc. However, due to its low solubility, conventional dissolution methods require a long time and high temperature.

[0003] In the prior art, direct stirring and temperature control of the aqueous solution in the container are usually used to accelerate its dissolution rate. If the stirrer only rotates in one direction, as the stirring time increases, all the solutions in the entire container from top to bottom will rotate at the same speed, which is obviously not conducive to the rapid dissolution of anhydrous piperazine. If a forward and reverse stirring method is used, although the above-mentioned problems can be solved, the rotation direction of the motor is suddenly changed in a short period of time, and there is also resistance caused by water during the stirring process, which will cause a very large load on the motor, which is not conducive to the long-term use of the motor. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anhydrous piperazine rapid dissolution device to solve the problems encountered in actual use.

[0005] The utility model aims to provide a device for rapidly dissolving anhydrous piperazine to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A device for rapid dissolution of anhydrous piperazine comprises a mixing barrel and a stirring mechanism arranged in the mixing barrel for stirring, wherein the stirring mechanism comprises a driving motor and a driving rod and a plurality of stirrers with different rotation speeds arranged on the driving rod, wherein the output shaft of the driving motor is fixedly connected to the top end of the driving rod, and the driving motor is fixed to the top surface of the mixing barrel.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model can stir positions at different heights in the mixing barrel at different speeds by setting the rotation speeds of the stirrers differently, thereby forming a turbulent flow effect and improving the dissolution efficiency of anhydrous piperazine. Moreover, the stirrers are all driven by the same drive motor, thereby reducing equipment cost expenditure. BRIEF DESCRIPTION OF THE DRAWINGS
