Feed liquid stirring equipment for reaction kettle

Abstract

The invention discloses an agitator with synthetic motion, which comprises a stirring shaft, upper, middle and lower bushings, three paddles, a spring, a cam and a camshaft; the three bushings are respectively fixed to the three paddles Connection, the upper shaft sleeve and the middle shaft sleeve respectively form a sliding key connection with the stirring shaft, and the lower shaft sleeve is fixedly connected with the stirring shaft. The cam and the upper bushing form a cam pair. The benefit of the present invention is: when the stirring shaft makes the upper, middle and lower blades rotate together, the camshaft drives the cam to rotate, and due to the force locking effect of the spring, the upper bushing and the middle bushing are still rotating while rotating. The up and down reciprocating linear motion is generated on the stirring shaft. Therefore, the motion of the upper paddle and the middle paddle is a synthetic motion with simultaneous rotation and linear motion. Such stirring operation can make the feed liquid obtain greater axial flow, so that the feed liquid can be better circulated and mixed, and the stirring efficiency and uniformity are improved.

Description

technical field [0001] The invention relates to a stirrer for a reaction kettle, in particular to a material liquid stirring device for a reaction kettle, which belongs to the field of chemical mixing and stirring equipment. Background technique [0002] The general paddle agitator has a simple structure and is easy to manufacture. Its blades are usually made of flat steel, and are fixed on the hub by welding or bolting, and the hub is fixedly installed on a certain position of the stirring shaft. Because it can meet the general stirring requirements, it is a stirrer widely used in mechanically stirred reactors. However, the main disadvantage of this type of agitator is that because the position of the blade is fixed and the liquid flow in the direction of rotation is mainly generated during stirring, and the range of axial flow is small, therefore, when large axial flow is required This type of agitator cannot meet the requirements in the stirring operation condition that ...

Problems solved by technology

But the main disadvantage of this type of agitator is: since the blade position is fixed and the liquid flow in the direction of rotation is mainly generated when stirring, and the range of axial flow is small, therefore, when large axial flow is required This type of agitator cannot meet the requirements in the stirring operation condition that the material can be fully circulated and mixed.
