The feed inlet 6 is arranged above the stirrer body 1, and the feed inlet 6 is communicated with the discharge hole of the screw conveyer in a sealing way to realize the continuous conveying of raw materials. When the stirrer body 1 works, under the action of pressure, cement floating in the stirrer body 1 is discharged into slurry of the liquid level adjusting pipe 5 through the exhaust pipe 3, so that the purpose of self-dedusting of the stirrer body 1 is achieved; the liquid level of the slurry in the stirrer body 1 is reliably regulated by using the liquid level regulating pipe 5, the retention time of the slurry in the stirrer body 1 is controlled, and the preparation quality of the cementing slurry is improved; the equipment has the advantages of low cost, simple structure, convenient maintenance, good dust removal effect and the like.
Specifically, the liquid level adjusting pipe 5 is a multi-bending structure and sequentially comprises a horizontal pipe, an upward connecting bent pipe, an obliquely upward straight pipe, a downward connecting bent pipe and an obliquely downward straight pipe, and the horizontal pipe is connected with the discharge opening 4. An angle regulator is arranged between the horizontal pipe and the inclined upward straight pipe, and can regulate the horizontal angle theta of the inclined upward straight pipe, wherein the horizontal angle theta is within the range of more than or equal to 0 and less than 90 degrees. The highest point of the liquid level adjusting pipe 5 is lower than the height of the exhaust port 2 on the side wall of the blender body 1. Through the horizontal angle theta who adjusts the straight tube in the slant, and then adjust the highest point position of liquid level control pipe 5, can look over the liquid level in the mixer body 1 in real time, avoid the feeding too much, the ground paste surpasss the highest liquid level line, causes the incident. In addition, through the liquid level in the regulation and control mixer body 1, can avoid the direct discharge through discharge opening 4 of thick liquids in the mixer body 1, prolong the dwell time of the interior thick liquids of mixer body 1, further improve the preparation quality of cementitious slurry.
Particularly, the exhaust pipe 1 is a telescopic pipeline and is communicated with the pipe body of the liquid level adjusting pipe 5; the cement dust floating in the mixer body 1 is discharged into the slurry in the liquid level adjusting pipe 5. The exhaust pipe 3 is movably connected and sealed with the pipe body of the upward inclined straight pipe in the liquid level adjusting pipe 5. When the stirrer body 1 discharges materials through the discharge opening 4 and the liquid level adjusting pipe 5, the flow speed of slurry in the liquid level adjusting pipe 5 is high, and a pressure difference is formed in the exhaust pipe 3; the feeding speed in the stirrer body 1 is higher than the discharging speed, so that the pressure in the stirrer body 1 is increased; consequently, cement that drifts away in mixer body 1 can not only utilize liquid to filter the function that has realized the mixer from removing dust through 3 ground paste that get into liquid level control pipe 5 of blast pipe in, and the lime dust has avoided the waste of raw materials in directly getting into ground paste, still has green's meaning.
