The material on the blanking surface of each next level is shunted once, the more downward the material space is, the more easily the air flow blows through the material. During the powder selection process of the materials along the step-shaped L-shaped material cutting plate 7-1, the materials falling continuously rub and collide, and then are scrubbed by wind, so that the material accumulation on each layer of steps is changed continuously and is formed continuously. The ventilation structure 7 realizes efficient and targeted separation of dust of corresponding particle size.
Secondly, feeding: the powder concentrator can be used as a part of a chute, and the feeding mode adopts a connection conveyor or a vibration feeder for feeding.

Fifthly, blanking: the blanking port air locking device and the feeding air locking device are the same pin shaft and barrier plate assembly. The lower side of the blocking plate is arranged beside the flash side of the bottom L-shaped material cutting plate 7-1. The blanking air locking device effectively controls the air inlet amount.
The working principle of the feeding air locking device and the blanking air locking device is as follows: the structure is characterized in that a blocking plate with a certain length is connected with a rotating shaft, the blocking plate and a blanking space between the blocking plate and an L-shaped material cutting plate are compressed by the dead weight of a heavy hammer, only materials are allowed to pass through, and air is reduced as much as possible. The structure not only controls the back-moving air inlet amount of the interference flow-dividing airflow, but also can enable materials to be more uniform and dispersed to fall to the lower layer, and realizes the self-locking function. Materials of different types and different compositions need different stopping forces, the pressure of the stopping plate and the materials is determined by the self weight, the weight of the heavy hammer and the position of the heavy hammer, and the materials under various working conditions can be processed by properly designing the structural position.
Sixthly, a coarse material recovery cavity: the material of multilayer whereabouts, in the collision between the material, outside the great sand material of particle size fell the ventilation structure easily, set up coarse fodder recovery chamber in ventilation structure downside, can be used to retrieve the material that scatters heavier, the particle size is great at the air intake to guide to the blanking mouth. Because the coarse material recovery cavity and the air inlet are connected into a whole, the air inlet at the blanking port is controlled by the air locking device of the recovery cavity, and more importantly, the air inlet is ensured to completely enter the flow direction ventilation structure as far as possible during air inlet, so that the situation that the air inlet flows to the coarse material recovery cavity for shunting and overflowing is avoided.
The utility model discloses concrete example: referring to fig. 3 to 5, the recovery cavity wind-lock device 5 comprises at least two sets of the above-mentioned pin 5-2 and blocking plate 5-1 components, two shaft ends of the pin are installed on the casing, the upper side of the blocking plate 5-1 is connected with the pin 5-2, the lower side of the blocking plate 5-1 is contacted with the casing at the lower side of the chute channel, one set is arranged at the communication position of the coarse material recovery cavity and the air inlet channel 9, and is used for preventing coarse materials from accumulating in the air inlet channel; a set of setting is retrieved the chamber and is communicated department with blanking mouth 10 at coarse fodder, prevents that the air from this chamber gets into the organism and disturb the air inlet. In the novel example, each L-shaped material cutting plate of the ventilation structure is only provided with a ventilation interval between partial layers corresponding to the air inlet and the air induction port, the lower part of the L-shaped material cutting plate is completely connected with the upper layer and the lower layer without the ventilation interval, and the auxiliary air locking plate 5-3 is additionally arranged in the installation gap between the pin shaft 5-2 and the L-shaped material cutting plate 7-1, so that the passing air volume is reduced as much as possible. According to the design, after the blocking plates at the two ends of the coarse material recovery cavity are closed, the coarse material recovery cavity forms a fully-closed cavity, and the effect of closing an air passage is achieved. The pin shaft and the blocking plate assembly which are contained in the recovery cavity air locking device are not limited to two groups and are actually arranged according to working condition requirements. The arrangement of the outer side heavy hammers can be flexibly processed, and all the heavy hammers can be configured, or the heavy hammers can be configured in individual groups, or the heavy hammers are not required to be set, so that the actual working conditions are mainly met.
When the air blower forces to enter air, the air locking device of the recovery cavity mainly acts to prevent the air from flowing through the coarse material recovery cavity. When the air inlet naturally mends the wind, retrieve the chamber lock wind device mainly acts as and prevents that blanking mouth air from getting into coarse fodder and retrieving the chamber.
Seventhly, blanking: the blanking port is connected with the conveyor belt or the next-stage equipment, and the coarse material after powder selection is discharged from the outlet.
Eighthly, air distribution plate: the air distribution plate is used for adjusting the distribution of air pressure of inlet air, so that the air is uniformly dispersed on each operation surface. The wind inlet of the wind inlet channel is generally concentrated wind inlet, and the design principle of the wind distribution plate is that the part with concentrated wind power uses smaller holes, and the part with larger wind power uses larger holes, so that uneven wind power passing through the wind distribution plate is dispersed and averaged. Specifically, the air distribution plate 8 is provided with a plurality of air volume adjusting holes 8-1 according to the size of wind force received in unit area, the air volume adjusting holes are small when the wind force in unit area is large, and the air volume adjusting holes are large when the wind force in unit area is small.
