Description

Evaporative mixer

technical field

The utility model relates to the technical field of agitators, in particular to an evaporative mixing type agitator.

Background technique

Stirring is some kind of circulation through the stirrer, so that the gas, liquid and even suspended particles in the solution can be mixed evenly. In order to achieve this purpose, it needs to be achieved by means of forced convection and uniform mixing, that is, the internal components of the stirrer. Stirring is a commonly used operation in organic preparation experiments. The purpose is to fully mix the reactants to avoid the occurrence of side reactions or the decomposition of organic substances due to the uneven concentration of the reactants and the uneven heating. By stirring, the reactants are fully mixed and heated evenly, the reaction time is shortened, and the reaction yield is improved.

The types of mixers include mechanical mixers, airflow mixers and ultrasonic mixers. Among them, mechanical mixers are mainly used in food industry applications, including flat paddle mixers, propeller mixers, turbine mixers, and special mixers. (anchor mixer, squirrel cage mixer, planetary mixer), egg beater or blender. (1) Straight blade paddle agitator: at low speed, horizontal circulation type, laminar flow area operation. At high speed, runoff type. When there is a baffle, the power factor increases significantly, it is an upper and lower circulating flow, and the turbulent flow is enhanced. It is suitable for mixing, dispersing, solid suspension, heat transfer, liquid phase reaction and other processes of low viscosity liquid. (2) Turbine agitator: The flow pattern of the agitator is radial flow, and when there is a baffle plate, the upper and lower circulating flows are formed with the paddle as the boundary. It has high shear force and large circulation capacity, among which the straight blade opening turbine shear force is the largest, the curved blade opening turbine shear force is the smallest, and the inclined blade opening turbine shear force is in the middle. Straight-blade open turbines are more suitable for decentralized operation. The curved blade has good discharge performance, the blade is not easy to wear, and is more suitable for solid suspension and solid dissolution. Therefore, the turbo mixer is the mixer with the widest range of operation. (3) Egg beater or blender: Through the high-speed rotation (70-270r/rain) of its own stirring paddle and forced stirring, the material to be stirred is fully contacted and rubbed violently, so as to realize the mixing, emulsification, aeration and It can eliminate the effect of some water, so as to meet the requirements of special food processing technology, such as the production of aerated toffee, the aeration of ice cream, and the stirring and sanding of sand-type toffee. There are vertical and horizontal types of egg beaters or blenders. The structure of the vertical egg beater: it consists of a mixer, a container, a transmission device and a container lifting mechanism. The working process is as follows: the motor transmits the power to the transmission device, and then to the agitator, and a certain regular relative movement occurs between the agitator and the container, so that the material is stirred. The mixer of the vertical egg beater consists of a mixing head and a mixing paddle. ① Stirring head: The function of the stirring head is to make the stirring slurry form a certain regular movement track in the container. There are two ways: one is that the container does not move, and the stirring head drives the stirring paddle to make planetary motion; the other is that the container is installed on the rotating head, and the stirring head is eccentrically installed near the wall of the container for fixed rotation. ②Mixing paddle: There are three forms, namely hook shape, beat shape and basket shape

The existing frame-type agitators are mainly propelled axially, and the efficiency is low during the stirring process, and there is a disadvantage of uneven stirring.
