It is widely used in coatings, medicine, building materials, chemicals, pigments, resins, food, scientific research and other industries. In chemical stirring tanks, for example, the production process of triazophos is to put a variety of raw materials into the stirring tank for mixing.

A water pipe is installed on the mixing body, and the upper end of the water pipe is connected to an external water source. A cleaning cylinder is fixedly installed on the mixing rod. The cleaning cylinder is an upper cylindrical lower semi-spherical structure with an upper end opening. There are multiple groups of leakage holes around the cleaning cylinder. The lower end of the water pipe is arranged on the inner side of the cleaning cylinder. When the mixing body needs to be cleaned, the cleaning liquid is transported to the cleaning cylinder through the water pipe, and the motor drives the mixing rod to rotate. The cleaning cylinder rotates with the mixing rod, and the cleaning liquid in the cleaning cylinder is thrown out from the leakage hole by the centrifugal force generated during the rotation, thereby performing all-round automatic cleaning on the inside of the mixing body. A chemical raw material mixing agitator of the present application achieves the effect of efficient cleaning.

By setting the rotating shaft 72, the rotating shaft 72 is rotatably connected to the support plate 3 through a bearing, so that the rotating shaft 72 can be ensured not to shake or disengage during the rotation process;

[0035] The rotating shaft 72 is rotatably connected in the support plate 3, a connector 73 is connected under the rotating shaft 72, a connecting column 74 is connected under the connector 73, four long slots 75 are opened in the connecting column 74, an electric push rod 76 is connected in the long slot 75, and a scraper 77 is connected at one end of the electric push rod 76 away from the long slot 75. The scraper 77 is set as a rubber plate that is easy to fit on the inner wall of the mixing barrel 6.
