Description

Evaporation mixing type stirrer

Technical Field

The utility model relates to a stirrer technical field specifically is evaporation hybrid agitator.

Background

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, and the reaction yield is improved.

The types of mixers include mechanical mixers, gas flow mixers, ultrasonic mixers, etc., wherein the food industry uses mechanical mixers as the main part, including flat blade mixers, propeller mixers, turbine mixers, special mixers (anchor mixers, squirrel cage mixers, planetary mixers), egg beaters or blenders. (1) Straight blade paddle stirrer: at low speed, the laminar flow region operates in a horizontal loop mode. At high speed, the flow is radial. When the baffle is arranged, the power quasi-number is obviously increased, the power quasi-number is an up-and-down circulating flow, the turbulence is enhanced, and the device is suitable for the processes of mixing, dispersing, solid suspension, heat transfer, liquid phase reaction and the like of low-viscosity liquid. (2) Turbine agitator: the flow pattern of the stirrer is radial flow, and an upper circulating flow and a lower circulating flow are formed by taking the blades as boundaries when the baffle is arranged. The high-shear impeller has high shear force and large circulation capacity, wherein the straight blade opening turbine type shear force is the largest, the bent blade opening turbine type shear force is the smallest, and the inclined blade opening turbine type shear force is centered. Straight vane opening turbines are more suitable for decentralized operation. The bent blade has good discharge performance, the blades are not easy to wear, and the bent blade is more suitable for solid suspension and solid dissolution. Therefore, the turbine stirrer is the stirrer with the widest applicable range in the operation process. (3) Eggbeater or blender: the materials to be stirred are fully contacted and violently rubbed through the high-speed rotation (70-270 r/rain) and the forced stirring of the stirring pulp, so that the effects of mixing, emulsifying, aerating and removing partial water of the materials are realized, and the requirements of special processing technologies of certain foods are met, such as aeration for producing aerated toffee, aeration for ice cream, stirring and sanding for sand-type toffee and the like. The egg beater or the blender is divided into a vertical type and a horizontal type. The structure of the vertical eggbeater is as follows: it is composed of stirrer, container, driver and lifting mechanism of container. The working process is as follows: the motor transmits power to the transmission device and then to the stirrer, and the stirrer and the container generate relative motion in a certain rule, so that the materials are stirred. The stirrer of the vertical eggbeater consists of a stirring head and a stirring paddle. Firstly, a stirring head: the stirring head is used for enabling the stirring paddle to form a certain regular motion track in the container. The method comprises two modes: the first is that the container is fixed, the stirring head drives the stirring paddle to do planetary motion; the other is that the container is arranged on a rotating head, and the stirring head is eccentrically arranged close to the container wall to perform fixed rotation. Stirring the slurry: has three forms, namely hook, bat and basket

The existing frame type stirrer mainly adopts a push type axial direction, has low efficiency in the stirring process and has the defect of uneven stirring.
