[0004] The utility model is realized as follows: a powder feeding and stirring device for preventing compaction of a dialysis centralized liquid supply raw material box comprises a powder barrel, a powder stirring shaft, a powder stirring plate, a powder scraping plate and a reduction motor, wherein the top plate and the side wall of the powder barrel are closed, and a powder feeding screen is arranged on the bottom plate of the powder barrel; a powder stirring shaft is arranged in the center of the powder barrel, the upper part of the powder stirring shaft is connected to the reduction motor fixed on the top of the powder barrel, a powder stirring bracket is arranged at the lower part of the powder stirring shaft, the powder stirring plate and the powder scraping plate are arranged on the powder stirring bracket, and a gap is arranged between the bottom of the powder stirring plate and the bottom plate of the powder barrel; and the bottom of the powder scraping plate contacts with the bottom plate of the powder barrel.

[0005] Furthermore, the powder stirring plate and the powder scraping plate are mounted on the powder stirring bracket by means of bolts.

[0006] Furthermore, the powder stirring shaft is installed in the bottom plate of the powder barrel through a powder stirring shaft seat.

[0007] Furthermore, the powder barrel is made of PP material.

[0008] Furthermore, the powder scraper is made of silicone.

[0009] Furthermore, the powder stirring plate is made of stainless steel.

[0010] Furthermore, a material sensor is installed on the side wall of the powder barrel to detect the amount of powder in the barrel.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when powder is fed in, the motor starts, drives the stirring mechanism to rotate, stirs the dialysis powder, prevents the dialysis powder from agglomerating and unevenly distributing, and ensures that the dialysis powder can smoothly leak out of the powder feeding screen. The bottom of the powder scraper plate contacts the bottom plate of the powder barrel and the powder feeding screen, scrapes the powder during the rotation, and prevents agglomerated dialysis powder from entering. The material sensor is installed on the barrel wall, which can detect the amount of powder in the barrel. BRIEF DESCRIPTION OF THE DRAWINGS
