Abstract

The invention relates to a preparation device for a viscoelasticity high-molecular polymer aqueous solution. An outer shell of a cavity is placed in a support. A blade and a disperser are placed in the cavity. The blade penetrates through a rotary shaft of the disperser to be connected with a speed adjusting motor. A scraping piece of the disperser rotates along with the rotary shaft. An interlayer space is arranged between the cavity and the outer shell. A temperature control device is connected with the interlayer space to form a loop, and water temperature in the cavity reaches dynamic equilibrium through the temperature control device. In the preparation device, high-molecular polymer solute enters water periodically and can dissolve in water evenly through high-degree-of-freedom stirring action of a stirrer. The stirred speed of the solution in the cavity can be controlled by the speed adjusting motor on the stirrer, the shearing action on fluid can be reduced, damage to a high-molecular polymer molecular chain is reduced, hydrophobic coatings are applied on the surfaces of blades of the stirrer, adhesion of polymer molecules can be reduced, after preparation, hot water in the temperature control device can be led out to wash the blades and the inner wall of the cavity, and solute residues are prevented.

Description

technical field [0001] The invention relates to a solution preparation device, in particular to a preparation device for a viscoelastic polymer aqueous solution, and belongs to the technical field of solution preparation devices. Background technique [0002] A search of existing literature reveals that the current solution preparation device is mainly composed of a cylindrical barrel and a blade group driven by a motor. The solute and solvent are directly placed in the cylindrical barrel, and the blade group rotates to make the solution evenly mixed. For the preparation of a viscoelastic high molecular polymer solution, this method is easy to cause the rapid degradation of the high molecular polymer solute, and the solute is easy to adhere to the stirring blade, the uniformity of the solution is poor, and the temperature changes greatly. The effect is not ideal. In actual demand, the solution is often required to have high uniformity. During the preparation process, the s...
