Problems solved by technology

[0007] 2. With the continuous dissolution of the polymer in water, the viscosity and flow resistance of the aqueous solution also increase, and the farther away from the stirring paddle, the slower the rotation speed of the solution
[0009] When preparing polymers in each indoor test, the stirring time is generally more than half an hour. In order to achieve the design viscosity, the concentration of the polymer can only be increased to compensate for the viscosity loss caused by mechanical shearing, which increases unnecessary costs.

Embodiment Construction

[0033] The adjustable stirrer of the embodiment of the present invention is mainly used for stirring in the indoor test preparation process of high molecular polymer aqueous solution. The problem of axial rod climbing of the polymer during the dissolution process, the lower stirring speed effectively alleviates the problem of viscosity loss of the polymer solution due to mechanical rotational shearing, and improves the stirring efficiency. Specifically, it solves the four major problems existing in the current paddle mixer. First, it solves the axial rod climbing problem of the high molecular polymer during the swelling process with the revolution of the stirring plate; second, it alleviates the problem of viscosity loss of the polymer solution due to mechanical shear at a lower speed; Third, the two opposite stirring blades of the adjustable mixer can adjust the distance from the center synchronously and horizontally within a certain range according to the inner diameter of t...

Abstract

The invention discloses an adjustable stirring machine which comprises a motor device and a stirring device; conventional high speed rotating blade type stirring is changed into revolution stirring piece type low speed stirring; no rotary center rotating shaft is arranged at the part, immersed into liquid, of the adjustable stirring machine, so that the phenomenon that the polymer 'climbs rods' in the stirring process is avoided, the stirring effect is relatively completed, and viscosity loss of the polymer solution caused by mechanical shearing of high speed rotation of a blade stirring machine can be effectively reduced.

Description

technical field [0001] The present application relates to the field of petrochemical industry, in particular to an adjustable mixer. Background technique [0002] Polyacrylamide is a water-soluble polymer (hereinafter referred to as polymer). In recent years, due to its unique characteristics, its application field has gradually expanded. At present, the polymer is widely used in oilfield industry, water treatment, papermaking, textile printing and dyeing, mining and other fields. [0003] In the petroleum industry, due to the polymer thickening properties of this polymer, it is widely used in drilling fluid thickening and lubrication, oil recovery, profile control, water shutoff and other processes. [0004] In order to ensure or improve the application effect, a large number of laboratory tests are required before the application of the polymer, and the application process must be continuously adjusted through laboratory tests. In laboratory experiments, the preparation ...
