Problems solved by technology

However, this kind of agitator structure has disadvantages: the number of times the material is turned during the stirring process is small, and because the polymerization of carboxylated styrene-butadiene latex is an exothermic process, it is required to strictly control the polymerization temperature. It is easy to produce gel, reduce the heat transfer effect, and shorten the cleaning cycle

Embodiment Construction

[0012] See figure 1 , figure 2 , image 3 , Figure 4 , including the reactor body, stirring shaft 1, and agitator. The agitator includes a slanted-blade paddle agitator 2 and a wide-blade paddle agitator 3 located at the lower head. The agitator is fixed on the stirring shaft 1. The blades of the device 2 include an inner half blade 2-1 and an outer half blade 2-2 respectively, and the inner half blade 2-1 and the outer half blade 2-2 maintain an angle after being twisted at the joint, and the oblique blades At the junction of the inner half blade 2-1 and the outer half blade 2-2 of the paddle agitator 2, four gaps are opened at four points on the edge, and the part surrounded by the four gaps is the inner half blade The twist section 2-3 between 2-1 and the outer half blade 2-2, when twisted, the inner half blade 2-1 does not move, only needs to clamp the outer half blade 2-2 to rotate, twist Section 2-3 just twists, and it is easier to implement twisting through four g...

Abstract

The invention provides an improved structure of a blender in a polymerization kettle, which is capable of increasing times for overturning materials, reducing a temperature difference of the materials in the kettle in the process of blending, increasing the blending efficiency, avoiding the generation of gel and prolonging the cycle of cleaning the kettle. The improved structure comprises a reaction kettle body, a blending shaft and the blender; the blender comprises a pitched blade type blender and a wide blade type blender which is located on a lower seal head; the blender is fixed on the blending shaft, wherein blades of the pitched blade type blender respectively include an inner semi-blade and an outer semi-blade, and an included angle is kept between the inner semi-blade and the outer semi-blade after the inner semi-blade and the outer semi-blade are screwed at a connection part.

Description

technical field [0001] The invention relates to a stirrer device, in particular to a structure of a stirrer in a polymerization tank, in particular to an improved structure of a stirrer in a polymerization tank. Background technique [0002] The polymerization kettle is the main equipment used to prepare polymer compounds. It is generally a vertical cylindrical autoclave, and the common one is a carboxylated styrene-butadiene latex polymerization kettle. Most of the agitators used are oblique-blade paddle agitators. Due to the relatively large height and diameter of the agitating device, multi-layer agitating blades are usually used. The head is equipped with a wide-leaf agitator, which is located at the lower end of the inclined-blade paddle agitator. effect. However, this kind of agitator structure has disadvantages: the number of times the material is turned during the stirring process is small, and because the polymerization of carboxylated styrene-butadiene latex is a...
