Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a detachable multi-blade stirring rod. Background Art

[0002] In the production process of chemical products, mechanical stirring is often used to mix the substances in the reaction bottle. However, the common stirring rod has only one blade and cannot be disassembled. When the height of the reaction container reaches a certain value, the single-blade stirring rod is not enough to mix all the substances in the container evenly. In the case of a reaction with a large amount of heat release, it is easy to generate high temperature locally in the container, thus causing safety accidents. To solve this problem, the number of blades needs to be increased;

[0003] Chinese Public Invention: CN202220704637.9 A detachable multi-blade stirring rod. The detachable multi-blade stirring rod consists of a rod body, fan blades, a limit assembly and a clamping assembly. There is a small hole perpendicular to the rod body in the rod body, and the inner wall of the small hole is threaded, which is interconnected with the clamping assembly integrally formed on the blade. The surface of the clamping assembly is threaded, which matches the thread of the small hole in the rod body to form a relationship between a nut and a screw. At the same time, the limit assembly connected to the clamping assembly controls the depth when the clamping assembly is connected to the rod body, so that blades can be inserted at both ends of the rod body. There are multiple threaded holes on the rod body, and the number of blades can be increased or decreased as needed to meet production needs. At the same time, it is equipped with a condensation reactor that can be connected to an external water source, which helps to carry out the reaction safely and efficiently;

[0004] The blade is tightened by a thread, and its angle will be different due to different tightening degrees. The circumferential and axial movement speeds of the material will also change with the blade angle, and the resistance of the material will drive the blade to rotate, causing the thread to loosen. Its stability is poor, which is not convenient for the production of chemical products.

[0005] Therefore, a detachable multi-blade stirring rod is proposed. Utility Model Content

[0008] As a further preferred embodiment of the present technical solution: a connecting flange is fixedly connected to the upper surface of the rod body.

[0009] As a further preferred embodiment of the present technical solution: uniformly distributed reinforcing ribs are fixedly connected between the lower surface of the connecting flange and the outer side wall of the rod body.

The stirring blade and the mounting ring are welded and are not easy to rotate. The mounting block does not need to open a hole on the rod body, and is not easy to affect the strength of the rod body, and the mounting block can prevent the mounting ring from rotating along the rod body. When reducing the stirring blade, the threaded rod is unscrewed to remove the mounting ring, and then the threaded rod is completely screwed into the threaded hole, which can prevent the threaded hole from being blocked by the material, and can prevent the thread on the threaded rod from being corroded by the material and losing the tightening ability. It has good stability and is convenient for the production of chemical products. BRIEF DESCRIPTION OF THE DRAWINGS
