Therefore, the powder flow rate can be determined by knowing the rotation speed. The screw feeder 11 has a powder inlet 111 at one end and a powder outlet 112 at the other end, the powder inlet 111 facing upward and the powder outlet 112 facing downward. The powder inlet 111 is connected to the raw material tube, and powder enters the screw feeder 11 from the raw material tube through the powder inlet 111. The axis of the screw feeder 11 is arranged obliquely, and one end driven by the feeder motor 13 is higher than the other end, so that powder can not fall freely under the action of gravity to cause inaccurate metering.

The working principle of the embodiment is as follows: powder stored in the external raw material barrel falls into the powder feeding device 1 through the powder inlet 111, and is vertically dropped onto the inclined plate 51 from the powder outlet 112 under the spiral pushing of the inclined upward direction, and the powder is uniformly distributed on the inclined plate 51. The powder flow rate of the conveying is related to the diameter and the rotating speed of the rotor, the powder flow rate is in direct proportion to the sectional area and the rotating speed of the spiral rotor, and under the condition that the diameter of the rotor is fixed, the powder flow rate is in direct proportion to the rotating speed, so that the powder flow rate can be determined by knowing the rotating speed.

After flowing out from the liquid outlet 23, the liquid is deflected by the baffle plate 113 and falls vertically on the inclined plate 51, and at the same time, the liquid is uniformly distributed on the inclined plate 51 and uniformly flows down along the inclined plate 51. The liquid flowing downward at this time just washes away the powder distributed on the inclined plate 51 and is primarily mixed with the powder. The liquid-powder mixture flows down along the inclined surface 51 until it falls into the shearing cylinder 32, and the powder-liquid mixture becomes homogeneous slurry under the stirring, dispersing and homogenizing action of the centrifugal blade 31, and finally the slurry flows out from the rectangular hole in the lower portion of the shearing cylinder 32 into the slurry container 5. In the slurry container 5, the rotation speed of the stirring paddle of the stabilizing stirrer 4 is low, and the action range is the slurry in the whole slurry container 5, so as to stabilize the slurry and keep the slurry uniform, thereby preventing the powder from being dehydrated, agglomerated and separated out.

the mixing uniformity is high, and the two stirring links have double functions of stirring and homogenizing, so that the stirring and homogenizing effect and the production efficiency are improved; simple structure, high reliability, low maintenance cost and high economic benefit.
