[0002] A powder classifier is a device used to separate and screen powdery materials. It is widely used in industries such as powder industry and food processing. Its purpose is to classify materials according to characteristics such as particle size and density through physical or airflow separation to improve product quality and production efficiency.
[0003] Most air classifiers are too large to be convenient to place, while smaller air classifiers can only perform short-distance, single-pass material separation, resulting in excessive residual dust in the material, leading to energy waste in secondary screening and inconvenience for subsequent processing. To solve the above problems, we propose a new type of air classifier. Utility Model Content

A horizontally positioned air guide cabinet 2 is slidably inserted into the groove. A blower 3 is mounted on the top of the air guide cabinet 2. The air guide cabinet 2 is angled at a right angle, with its inner side curved. A support plate 4 is vertically connected to the right end of the air guide cabinet 2, near its front end, with its bottom end fitting against the curved surface. A horizontally positioned guide hopper 5 is rotatably connected between the support plate 4 and the inner rear wall of the housing 1. Four rotationally symmetrical guide plates about the guide hopper 5 are fixedly connected to the outer wall of the guide hopper 5. The width of the guide plates is the same as the width of the air guide cabinet 2. A square feed hole is located at the top of the housing 1, directly above the guide hopper 5. A feed frame 17 is vertically connected to the feed hole. A motor unit 6 is vertically positioned at the rear end of the housing 1, containing a first motor and two second motors. The drive end of the first motor is fixedly connected to the rear end of the guide hopper 5.
[0018] An arc panel 7 is vertically connected to the inner rear wall of the housing 1, with its bottom end fitting against the inner bottom wall of the housing 1. The bottom end of the arc panel 7 is inclined, and the connection between the vertical end and the inclined end is arc-shaped. A support rod 8 is vertically connected to the top of the arc panel 7 and is located at the front end of the arc panel 7. Four horizontally arranged rotating rods 9 are movably inserted into both the support rod 8 and the rear end of the housing 1. The four rotating rods 9 on the same side are arranged vertically in a linear fashion. The support rod 8 and the four rotating rods 9 at the rear end of the housing 1 correspond to each other in pairs. Slots are provided at the near ends of the two corresponding rotating rods 9, and adjusting blades 10 are fixedly inserted into the slots. The front ends of the four rotating rods 9 on the support rod 8 are fixedly connected to a vertically arranged traction shaft 11. A rotating handle 12 is fixedly connected to the rear end of the first rotating rod 9 on the upper rear end of the box 1. The gap of the four adjusting blades 10 can be adjusted by the rotating handle 12 to control the size of the discharged dust particles. A horizontally arranged discharge frame is fixedly connected to the bottom end of the box 1, and a discharge mechanism is provided in the discharge frame.
[0019] In use, materials are fed into the box 1 through the feeding frame 17 at the top of the box 1. The material is then scattered between the bottom of the air guide cabinet 2 and the arc panel 7 by the guide hopper 5 driven by the motor 1. The blower 3 drives the airflow out from the bottom of the air guide cabinet 2, causing the material falling into the air outlet to be screened by the wind. The dust is blown upward along the arc panel 7 by the wind and poured into its right side through the four adjusting blades 10. The material that is not blown in will move in a circle along the upper right corner of the box 1 and finally fall into the air outlet of the air guide cabinet 2 for secondary screening. The discharge structure includes four rotating shafts 13. The discharge frame is set in an I-shape and the four rotating shafts 13 are horizontally distributed in pairs on the left and right sides inside the discharge frame. The two rotating shafts 13 on the same side are fitted with a conveyor belt 14. The left end of the arc panel 7 and the right end of the conveyor belt 14 on the left side are on the same side. In a vertical line, the rear ends of the two rotating shafts 13 located in the middle of the discharge frame are fixedly connected to the drive ends of the two motors 2 in the motor group 6. The right end of the box 1 is provided with a vent hole and is at the same height as the four adjusting blades 10. A breathable membrane 15 for blocking dust is provided in the vent hole. The front end of the box 1 is provided with a vertically arranged slide groove. A glass slide window 16 is slidably connected in the slide groove and is located between the guide hopper 5 and the adjusting blades 10. The internal condition of the box 1 can be observed through the glass slide window 16. The internal condition of the box 1 can also be cleaned or repaired by opening the glass slide window 16. Finally, the unblown material is screened and moves down along the arc panel 7 to the left conveyor belt 14 for discharge. The dust material will be blown to the right side of the arc panel 7, where the breathable membrane 15 intercepts the dust and discharges the gas. The dust will fall onto the right conveyor belt 14 for discharge.
