Description

Alkali-free liquid accelerator mixing stirring device

Technical Field

The utility model belongs to the technical field of liquid stirring, specifically be a mixed agitating unit of alkali-free liquid accelerator.

Background

The alkali-free liquid accelerator is a concrete additive used in sprayed concrete and is in a liquid state. The national standard GB/T35159-2017 accelerator for sprayed concrete is specifically defined for an alkali-free liquid accelerator: the equivalent content of sodium oxide is not more than 1.0 percent; the PH value is more than or equal to 2.0 and is controlled within +/-1 in a production plant; the 28d compressive strength ratio is more than or equal to 90 percent; the retention rate of the 90d compressive strength is more than or equal to 100 percent; the mixing amount is 6-9%, and the solution or suspension is generally formed by compounding aluminum salt and acid.

Stirring is to make a certain circulation through a stirrer, so that gas, liquid and even suspended particles in the solution are uniformly mixed. To achieve this, it is necessary to use a forced convection, homogeneous mixing device, i.e., the internal components of the stirrer. Stirring is a common operation in organic preparation experiments, and aims to ensure that reactants are fully mixed and avoid side reactions or organic matter decomposition caused by nonuniform concentration, local overlarge heating of the reactants. Through stirring, the reactants are fully mixed and uniformly heated, the reaction time is shortened, the reaction yield is improved, and the movement of liquid in the stirring tank is divided into total flow and turbulent flow pulsation in scale. The flow rate of the bulk flow is called the circulation amount, and increasing the circulation amount is beneficial to improving the degree of mixing (see the degree of mixing) of the macro mixing. The intensity of the turbulence pulsation is related to the speed of the fluid when leaving the stirrer, and the enhancement of the turbulence pulsation is beneficial to reducing the separation dimension and the separation intensity. Different processes have different requirements for these two flows. The dispersion of liquid drops and air bubbles requires strong turbulence pulsation; uniform suspension of solid particles relies on bulk flow. The distribution of energy over these two flows during mixing is an important issue in mixer design. When the mixture is stirred, the density difference, viscosity and interfacial tension of the two phases have a great influence on the stirring operation. The smaller the density difference and the interfacial tension, the more easily the system can achieve stable dispersion; the higher the viscosity, the more unfavorable the formation of good circulation flow and sufficient turbulent pulsation, and the consumption of large stirring power. The movement of the fluid within the stirred tank is a complex single-phase or multi-phase flow. The stirring of non-newtonian fluids has some special rules in terms of flow conditions and power consumption.

The existing stirring device has the defects that the blades of the existing stirring device mostly rotate in situ to cause insufficient mixing of the top and the bottom of the stirred liquid and uneven stirring and caking frequently occur, and the stirring barrel has complicated and complicated steps in the processes of charging and transporting and is inconvenient.
