Adjustable n-shaped mixer

Abstract

The invention relates to an adjustable n-shaped mixer. The mixer is in an n shape. A motor connecting shaft which is connected with a motor is arranged on the upper portion of the mixer. A cuboid screw type mixing blade adjuster is welded to the lower end of the motor connecting shaft. Tooth sliding blocks which are located in a slideway and engaged with the slideway are pushed by rotating a screw, so that mixing blades fixed to the lower portions of the tooth sliding blocks are driven, and the distance between the two mixing blades is adjusted to be adapted to different cylindrical containers. Each mixing blade is in the shape of an inverted L, and in order to improve the mixing effect, the included angle between the transverse direction of the mixing part of each mixing blade and the tangent line of a rotating arc of the mixing part of the mixing blade is 35 degrees. The purpose of even mixing is achieved through revolution of the mixing blades and a lower revolution speed, and thus side effects of mechanical shearing on a polymer solution are reduced to the maximum extent in the preparation process. The adjustable n-shaped mixer is mainly used for stirring in the indoor polymer solution preparation process.

Description

technical field [0001] The invention relates to an instrument and equipment for stirring a high molecular polymer in the process of preparing an aqueous solution, in particular to an adjustable n-type stirrer. Background technique [0002] In recent years, due to the unique characteristics of water-soluble polymers (hereinafter referred to as polymers), their application fields have gradually expanded, and they are widely used in oil field industry, water treatment, papermaking, textile printing and dyeing, mining and other fields. It is mainly used in the thickening and lubrication of drilling fluids mainly by using its polymer thickening characteristics. In the process of oil recovery, it is used for enhanced oil recovery, profile control, water plugging measures, etc. In order to ensure or improve the application effect, it must be carried out before application. A large number of indoor and field tests must be constantly adjusted through indoor tests during the applicati...

Problems solved by technology

[0003] 1. Due to the unique polymer properties of the polymer, an "axial climbing rod" phenomenon occurs during the dissolution process. As the central axis gradually climbs up, this phenomenon will also become serious with the increase of the polymer concentration in the water. The polymer wrapped around the central axis is difficult to dissolve into the water, and the inaccurate and inaccurate polymer concentration in the water appears. Inhomogeneity

[0004] 2. With the continuous dissolution of the polymer in water, the viscosity of the aqueous solution is increasing, and the flow resistance is also increasing. The farther away from the stirring paddle, the slower the rotation speed of the solutio
