Problems solved by technology
[0002] At present, the stirrers for various reactors mostly adopt the form of frame type, paddle type, anchor type, etc. For the stirring reaction of some high-viscosity materials, such as polyacrylate polymerization reaction, etc., the stirring requirements are very strict, and the stirring is required to be very uniform. Because polyacrylate polymerization often adopts bulk polymerization or solution polymerization, the viscosity changes greatly during the reaction process, from the initial very low centipoise number to the very high centipoise number, so the traditional stirring method often results in poor stirring. Uniform, insufficient, or even "agglomeration" of high-viscosity materials due to high material viscosity, traditional stirring methods cannot fully mix it with surrounding materials, and various additives do not completely enter the reaction zone

Embodiment Construction
[0009] Such as figure 1 As shown, a stirring frame (3) is set on the stirring shaft (2) of the reactor (1), and the stirring frame (3) takes the stirring shaft (2) as the axis of rotation, and its plane should be straight to the stirring shaft ( 2), the rotating surface should conform to the barrel-shaped inner wall of the reaction kettle (1), the stirring frame (3) is composed of banner strips (4) and vertical banner strips (5), installed around the stirring shaft (2) superior.
[0010] Set the lower stirring blade (7) at the lower end of the stirring frame (3) close to the bottom of the reactor. The lower stirring blade (7) takes the stirring shaft (2) as the axis of rotation, and its plane should be straight to the stirring axis. Axle (2), its surface of rotation should coincide with the shape at the bottom of the circular kettle of reaction kettle (1).
[0011] Open holes (6) are set on the stirring frame (3) banner strip (4), vertical banner strip (5) and the lower stir...

The invention provides an underlying big blade open-hole frame agitator for a reaction kettle. The underlying big blade open-hole frame agitator is applicable to chemical equipment, in particular to a reaction kettle for reacting and processing high-viscosity materials in the chemical equipment. The main technical scheme of the invention is as follows: an agitating frame is arranged on an agitating shaft of the reaction kettle, and the agitating frame comprises transverse spokes and vertical spokes and is installed around the agitating shaft; an underlying big agitating blade is arranged at the lower end of the agitating frame, which is near the bottom of the reaction kettle; and the transverse spokes and the vertical spokes of the agitating frame and the underlying big agitating blade are provided with open holes, the hole size diameter of each open hole is greater than 5 mm, and the area of the open hole on the underlying big agitating blade is greater than 25%.
Description
Technical field: [0001] The utility model relates to a frame-type agitator with a large leaf opening at the bottom for a reaction kettle, which is used for chemical equipment, and is especially suitable for a reaction kettle for reacting high-viscosity materials in the chemical equipment. Background technique: [0002] At present, the stirrers for various reactors mostly adopt the form of frame type, paddle type, anchor type, etc. For the stirring reaction of some high-viscosity materials, such as polyacrylate polymerization reaction, etc., the stirring requirements are very strict, and the stirring is required to be very uniform. Because polyacrylate polymerization often adopts bulk polymerization or solution polymerization, the viscosity changes greatly during the reaction process, from the initial very low centipoise number to the very high centipoise number, so the traditional stirring method often results in poor stirring. Uniform, insufficient, or even "agglomeration" ...
