In this embodiment, the hopper mechanism 2 is connected to the frame 1 through a hopper support plate, the hopper mechanism 2 has a dustpan-shaped structure with an inclination angle ranging from 10 ° to 30 ° at the outlet side lower than the rear wall side, and the hopper mechanism can be selected during assembly according to the flow characteristics of the powder. The outlet of the hopper mechanism 2 is on the same vertical plane with the center of the bin mechanism 4, and a certain distance is kept. The width of the hopper mechanism 2 is slightly smaller than the width of the bin mechanism 4 to avoid powder falling from the hopper to the outside of the bin. The hopper vibrator 21 is also arranged on the rear side wall of the hopper mechanism, plays a role in vibration-assisted blanking, can disperse and move down the fallen powder, and avoids the powder from accumulating into a pile.
In this embodiment, the screen mechanism 3 is connected with the top of the bin mechanism 4, the screen mechanism 3 includes a screen 31, a frame 33 and a bottom fixing plate 35, the screen 31 is located between the frame 33 and the bottom fixing plate 35, the screen is detachable and replaceable, the bottom fixing plate 35 is provided with a bolt hole 34, the bottom fixing plate 35 and the compression frame are fixed by bolts, the frame 33 has a certain height, and the height range of the frame 33 is 5-10 cm. A small vibrator is also mounted on the frame 33 of the screen mechanism 3, which can accelerate the powder through the screen, avoiding the accumulation of the screen mechanism 3.
In this embodiment, the bin mechanism 4 is a triangular prism shape placed horizontally, a slit is formed between two side edges with the smallest angle, and is a bin outlet 44, the outlet is vertically downward, and the width of the outlet is smaller than 1cm, and can be adjusted during manufacturing equipment. The width of the bin mechanism 4 is slightly smaller than the width of the distribution area, so that powder can be ensured to fall into the distribution area completely. In the bin mechanism 4, a loosening shaft 41 capable of rotating under the drive of a driving device 43 is arranged above a bin outlet 44, the loosening shaft 41 is transversely arranged, the length of the loosening shaft is matched with the length of the bin outlet 44, the loosening shaft 41 is a rotating shaft, a plurality of blades are longitudinally and uniformly distributed on the circumference of the rotating shaft, and a certain gap is reserved between each blade and the wall of the bin mechanism 4. The loosening shaft is connected with a driving motor through a speed reducer, and the driving motor is preferably a variable frequency motor. The speed reducer and the driving motor are both fixed on the outer wall of the bin mechanism.
Further, a transverse adjusting rod 42 is arranged between the bin outlet 44 and the loosening shaft 41, the adjusting rod is a solid metal rod, the diameter of the metal rod is the same as that of the bin outlet 44, and the adjusting rod 42 is parallel to the loosening shaft 41 and can move up and down.

In the actual operation of the powder separation process such as magnetic separation, raw material powder is stored in a ton bag or a raw material storage tank. The powder in the ton bag is lifted above the hopper mechanism 2 by a forklift, and the lower part of the ton bag is opened, so that the powder falls into the hopper successively. Powder in the raw material tank falls into a hopper through a feeder such as a rotary valve. The blanking speed of both feeding modes can be controlled, and the blanking speed is controlled in operation, so that the height of the materials in the screen mechanism 3 is not more than 1/2 of the height of the frame 33. The screen mechanism 3 screens the feeding powder, a small amount of impurities mixed in the powder are intercepted, the feeding can be stopped when the screened impurities are more, and the feeding is continued after the screen is cleaned.
If the amount of the accumulated powder on the upper part of the adjusting rod 42 is large, the powder is easy to compact, the powder mobility is poor, the discharging speed is influenced, and the rotating loosening shaft 41 can loosen the powder on the upper part of the adjusting rod 42, so that the powder near the adjusting rod 42 has good mobility.

The present utility model is not limited to the above examples, and those skilled in the art will appreciate that the present utility model is capable of equally varying and improving within the spirit and scope of the present utility model.
