In the powder conveying technology, air blowing is a common means, air is blown into a pipeline, and the flow of the air is utilized to drive the powder to flow, so that the effect of conveying the powder is achieved. However, in practical application, in the process of transporting the powder in a long distance through a pipeline, the powder often deposits to cause blockage due to the fact that the powder has gravity, resistance is generated by friction between the powder and the pipeline, humidity of the powder is high, and the like. For example, chinese patent publication No. CN203291918U discloses a cement pre-pulverizing system with an air supply device, which utilizes the air supply principle to transport powder, and includes a ball mill and a bag dust collector, wherein a discharge tube of the bag dust collector is communicated with an inner cavity of the ball mill through a powder return tube, the discharge tube is connected to a powder transport mechanism through a pipeline, the powder transport mechanism is composed of an air supply chute, an air blower connected to the air supply chute through a pipeline, and a control valve arranged on the pipeline between the air supply chute and the air blower, a discharge port of the powder transport mechanism is connected to a powder discharge tube of the ball mill, and a material stop mechanism is arranged on the powder return tube. However, the air blower blows air from the inlet of the chute, the air force of the pipeline far away from the air blowing port is weakened due to friction between the blown air and the pipeline, and when the moisture and the quantity of the conveyed powder are large, blockage is easy to occur at the downstream section of the pipeline.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems, the powder conveying device is provided, and the problem that the downstream of the air conveying chute is easy to block is solved.

Further, the inclination angle between the air supply chute and the horizontal plane is 10-15 degrees. The inclination angle of 10-15 degrees can facilitate the transportation of the powder, and simultaneously, the influence on the transportation distance is small.
Further, the distance between two adjacent rows of the blast caps is 10cm, and the distance between two adjacent blast caps in the same row is 15 cm. The wind blows the powder after coming out of the wind cap, and the proper distance can ensure that most of the powder can be lifted, so that the powder is prevented from being accumulated.
Further, the hood is rotatably connected with the connecting pipe.
Further, the plurality of air holes extend in a direction which is either counterclockwise or clockwise with respect to the circumference of the hood. The reacting force of the wind coming out of each wind hole can push the wind cap to rotate along the same direction, so that the powder around the wind cap is blown up, and the powder conveying effect is better.
Further, the diameter of the hood is larger than that of the connecting pipe.
Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:
the utility model discloses a powder conveyor throws the powder from the dog-house and gets into in the wind send the chute, then lets in the air that flows in to the wind channel from the blast pipe, and the air in the wind channel sprays out from the hood through the connecting pipe, gets into in the wind send the chute, lifts up the powder, because the air that flows that gets into the wind and send the chute only exports of discharge gate, so the air that flows can drive the powder and remove toward the discharge gate, discharges from the discharge gate, accomplishes the transport of powder. The utility model discloses a powder conveyor's hood distributes everywhere in the wind send the chute for the wind-force distribution of wind send the chute each department is comparatively even, and can prevent that the powder from taking place at the accumulational condition in the wind send the chute, has solved the wind-force in the low reaches of wind send the chute and has leaded to appearing the problem of jam easily because of pipe resistance diminishes.
