The cellulose ether additive in the quantitative barrel 18 falls into the inner part of the silo 3 through the connecting pipe 20. At this time, the power of the motor 5 is turned on to drive the auger 9 to rotate, so as to change the vertical unloading mode and reduce the segregation caused by too fast unloading speed. At the same time, the rotation of the auger 9 drives the gear one 10 to rotate, thereby driving the two meshing gear twos 12 to rotate, and then driving the rotating shaft 11 and the plurality of stirring rods 13 to stir and mix the fly ash and the cellulose ether additive. They can be adsorbed on the surface of the mortar particles to increase the interaction force between the particles, so that the particles of different components are not easy to separate during the flow process. Through mechanical control and additive mixing, the segregation condition is further reduced, and the product quality is improved.
[0037] Secondly, after the discharging is completed, the rotating handle 22 is rotated to drive the screw rod 21 to move downward spirally, thereby driving the rubber inclined plate 23 and the two sliding blocks 24 to slide downward in the inner part of the fixed frame 7. Through the contact between the inclined edge and the notch on the discharge pipe 6, the rubber inclined plate 23 is squeezed to fill the gap, the sealing of the discharge pipe 6 is completed, and the powder is prevented from meeting moisture to form hard blocks and accumulating at the bottom and wall surface of the storage tank. Not only will this cause the fluidity of the fly ash to become poor, but also will cause the unloading port to be blocked, so that the unloading is uneven or even impossible, and the practicability of the equipment is improved.
[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
