Description

Technical Field

[0002] Thickener: Also known as thickener, it is a substance that can be added to the fracturing fluid to greatly increase its consistency. At present, in the production process of thickener, it is necessary to mix various raw materials after proportioning, so that the raw materials can be fully integrated, so as to achieve a better mixing effect between the raw materials, and then make the preparation effect of the thickener better. In the actual use of the existing mixing mechanism, although the basic mixing and stirring effect can be achieved, the thickener after mixing is relatively viscous, so that the residual thickener after taking the material adheres to the inner wall of the mixing barrel, which makes it inconvenient for the operator to take it out, affecting the subsequent production and processing of the thickener, and is not conducive to the use of the operator, so it needs to be improved.
