Description

Technical Field

[0001] The utility model relates to the technical field of stirring rods, in particular to a stirring rod for a reaction kettle. Background Art

[0002] Unsaturated resin, also known as unsaturated polyester resin, is a high molecular compound, mainly prepared by polycondensation reaction of raw materials such as dibasic acid, diol and unsaturated dibasic acid or anhydride. Unsaturated resin is usually a viscous liquid, having good fluidity, physical properties, chemical stability and processing performance.

[0003] In the prior art, during the production and processing of unsaturated resin, a stirring rod is required to stir the unsaturated resin to facilitate the mixing of raw materials. However, most of the existing stirring rods have simple structures and single functions, only playing a stirring role and not having the function of cleaning the inside of the stirring kettle. As a result, in the later stage, the staff needs to open the door of the reaction kettle and manually perform the cleaning operation, which is cumbersome and consumes a long time, and is not conducive to the production and processing of unsaturated resin.

A first bevel gear is fixedly connected to the output shaft of the motor, and a second bevel gear meshing with the first bevel gear is fixedly connected to the surface of the hollow tube.

[0008] Further, a plurality of through holes are formed on the surface of the stirring blade, and a reinforcing rib is fixedly connected between the inner end of the surface of the stirring blade and the side wall of the stirring rod.

[0009] Furthermore, a vertical rod is fixedly connected to the bottom end of the stirring rod, and a scraping plate is fixedly connected to the bottom end of the vertical rod.

[0010] Furthermore, a cover plate is detachably connected to the surface of the adapter box through a plurality of bolts, and a valve is arranged on the connecting pipe.
