Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, the embodiment of the present invention includes: the four storage bins 1 are used for storing clinker powder, slag powder, fly ash and other ingredients respectively, and the four storage bins 1 are used for storing other ingredients. Each storage bin 1 is provided with a discharging valve 2, the discharging valve 2 is a gate valve, and an actuating mechanism of the discharging valve 2 is an electric actuating mechanism. And a belt type constant feeder 3 is arranged below each blanking valve 2, and a discharge port of each belt type constant feeder 3 is connected with a conveying device 4. The conveying device 4 is an air conveying chute, so that the powder material is conveniently conveyed into subsequent equipment, and the power source of the conveying device is a centrifugal fan.

As shown in fig. 2, the conveying device is connected to a mixer 5, which includes: the blending bunker, the blending bunker divide into upper bin 501 and lower storehouse 502, is equipped with orifice plate 503 between upper bin 501 and lower storehouse 502 storehouse, and one side of orifice plate 503 is equipped with filter cloth layer 504, is equipped with pivot 505 in the upper bin, connects stirring vane 506 in the pivot 505, and compounding driving motor 507 is connected to pivot 505, is equipped with feed inlet and discharge gate on the upper bin, is equipped with air intake 508 on the lower storehouse. The air intake communicates with the fan to blow in to lower floor's storehouse through the fan, make flow and get into upper storehouse through the orifice plate, and the filter cloth layer prevents that the powder material in the upper storehouse from getting into lower floor's storehouse, and the powder commodity circulation in the upper storehouse is blown to flow to the air current that flows, makes the powder material be full of upper storehouse, and stirring vane further mixes the powder material through the rotation simultaneously, reaches better mixed effect, with the hydration activity in improvement low clinker cement later stage.
