Stirring mechanism of double-layer stirrer

Abstract

The invention relates to a stirring mechanism of a double-layer stirrer. The stirring mechanism is connected with a stirring barrel; a stirring shaft comprises an inner pipe, an outer pipe and a rotating shaft, wherein the lower end of the inner pipe is in fixed connection with the bottom of the stirring barrel; a circular hole is arranged in the center of the bottom of the stirring barrel; the stirring shaft is rotarily arranged on the stirring barrel and disposed in the inner pipe and passes through the circular hole, the outer pipe is sleeved on the inner pipe, and the upper end of the outer pipe is in fixed connection with the upper end of the stirring shaft. According to the invention, the stirring shaft is arranged in the inner pipe, and through the fixedly arranged inner pipe, the problem of sealing between the stirring barrel at an upper layer and the stirring shaft is overcome, leakage does not occur, and extra wearing of the stirring shaft is avoided.

[0002] The mixing barrel of the double-layer mixer is divided into two layers by the partition plate, namely the upper and lower barrels. The upper barrel is mainly used for mixing operations, while the lower barrel is mainly used to collect and store the slurry stirred by the upper barrel and discharge it when needed. Slurry; the stirring shaft runs through the entire mixing barrel, extending from the upper barrel to the lower barrel. During the rotation of the stirring shaft, the gap between the stirring shaft and the partition plate is difficult to seal, which will cause the water in the upper layer of the mixing barrel to leak along the stirring shaft, making the stirring The upper layer of the barrel is short of water and the slurry in the lower layer of the discharge bin becomes thinner due to too much water, which causes serious wear between the stirring shaft and the partition plate

The leakage of the slurry will increase the wear of the stirring shaft and greatly reduce the service life; if the stirring shaft is not extended into the lower barrel for wear considerations, the slurry will settle in the lower barrel to make it uneven
