The fan blades are arranged in a clockwise or anticlockwise direction.
When the pneumatic separation device works, raw materials are conveyed into an upper air box by a conveying belt, a specially-made fan blade in a main air box is driven by a three-phase asynchronous motor through a V-belt to rotate, certain air pressure is generated in the main air box, the air is diffused into a lower air box through a reducing air channel, and then the air is blown upwards through a finished product receiving and filtering partition plate to form specific air quantity and air pressure, so that the material with enough specific gravity falls onto the filtering partition plate by gravity and slides out to a finished product discharge port, the material with the insufficient specific gravity (waste) is blown into the upper air box, and the material is blown out through a vent with height of 768mm (668mm-868mm) (the air discharge port height directly influences the pneumatic separation effect of the material) and slides out through a waste outlet. Simple structure, it is with low costs, can realize accurate the sorting as required.
The air pressure and the air volume in the main air box can be adjusted, and the air volume control blades are driven to rotate by rotating the air volume adjusting toothed bars, so that the size of the air inlet is determined by the opening and closing size of the blades. The rotation of the special fan blade is driven by a three-phase asynchronous motor through a triangular belt transmission mode to reach a specific rotating speed (in order to avoid the instant resistance generated by the fan blade during starting and further increase the instant current of the motor during starting, the triangular belt transmission mode is selected, so that the model selection power of the motor is reduced, and the energy-saving effect is achieved).
The specially-made fan blade is manufactured by adopting a special process, 12 blades are uniformly distributed on a bottom plate with the diameter of 600mm (phi 550 mm-phi 650mm), the rounding radius of the blades is R446mm (R400mm-R500mm), each blade and the bottom plate are inclined at about 8.65 degrees (6 degrees-10 degrees), and the fan blade manufactured by adopting the special manufacturing process rotates at a fixed rotating speed (the rotating speed of 890-970R/min when the motor is driven by 4.0KW and the rotating speed of 935-1015R/min when the motor is driven by 5.5 KW), so that the air volume and the air pressure of the fan blade reach a certain ratio which is 10 percent larger than the air volume generated when the standard No. 6 fan blade rotates at the same rotating speed, and a larger air volume is generated to ensure the air separation effect of products.
When the wind power generated by the rotation of the fan blades in the main wind box passes through the lower wind box, the wind power is partitioned by the air channel partition plate in the lower wind box, so that the wind power is uniformly distributed in the upward moving process of the lower wind box. The round steel of finished product filtration baffle in the lower bellows adopts phi 4mm (phi 3 mm-phi 5mm) round steel to arrange, and two round steel centre-to-centre separation 8mm (6mm-11mm), and this numerical value has guaranteed that the permeability of wind-force is not influenced, meets the condition of material leak-proof with the finished product, has avoided because of centre-to-centre separation is too wide, leads to the raw materials to drop, and centre-to-centre separation is too narrow, influences the permeability of wind-force, leads to the condition such as the raw materials screening is inhomogeneous. The lower air box air duct partition plate isolates the air duct into four areas by adopting the arc angle folded plate, and the arc angle is adopted to enable wind energy to smoothly move upwards, so that the problem that wind cannot smoothly pass due to a right-angle structure is avoided. The sizes of the round angles of each folded plate of the arc angles are different, the folded plates are partitioned by fixed sizes, and one wind shield is arranged on one side of the air inlet on the upper portion of the partition plate to ensure that the box body is uniformly filled with wind in the lower air box.
