Detailed Implementation

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] For reference Figures 1-4 As shown, this utility model proposes an airflow separation device for recycled aluminum crushed material, including a mounting frame 1, which is welded from square tubing. An airflow coarse separator 2 is fixedly connected to the mounting frame 1 for preliminary coarse separation of the material. A fine separation mechanism 3 is provided below the airflow coarse separator 2. The fine separation mechanism 3 includes an inclined vibrator, an airflow fine separator, and a blower 33. The inclined vibrator is located directly below the outlet of the airflow coarse separator 2, so that the material passing through the airflow coarse separator 2 can fall directly onto the inclined vibrator. The air intake of the airflow fine separator is located above the inclined vibrator, and the blower 33 is located below the inclined vibrator. The blower 33 is connected to the bottom end of the inclined vibrator through a flexible connection 331 to blow air onto the inclined vibrator from bottom to top, thereby blowing up the light and medium specific gravity material on the inclined vibrator to cooperate with the airflow fine separator to further separate the light and medium specific gravity material.

[0019] The airflow coarse separator 2 includes a sorting tank 21. The bottom of the sorting tank 21 is conical, and the side wall of the sorting tank 21 is fixedly connected to the mounting frame 1. A feed port 211 is also provided on the side wall of the sorting tank 21 for feeding crushed material into the sorting tank 21. A centrifugal exhaust fan 22 is installed at the top of the sorting tank 21. The centrifugal exhaust fan 22 can generate centrifugal suction inside the sorting tank 21, thereby enabling the adsorption of light plastics or impurities from the top outlet. The discharge port of the sorting tank 21 is located at the lower end, and a rotary plate gate valve 23 is installed on the discharge port for controlling the discharge.

[0020] The inclined vibrator includes an inclined vibrating box 31, inside which a grid plate 311 is fixedly connected, allowing material leaking from the outlet to fall directly onto the grid plate 311. The vibrating box 31 has a large material outlet 313 and a small material outlet 312 at its two ends, respectively. Both the large and small material outlets 313 and 312 are equipped with discharge plates 314, which are bolted to the vibrating box 31. The large material outlet 313 is located at the higher end of the vibrating box 31, and the small material outlet 312 is located at the lower end of the vibrating box 31.

[0021] The soft connection 331 is made of canvas and is set in a pyramid shape, and has a certain ductility, that is, it can adapt to the vibration action of the climbing vibrator; one end of the soft connection 331 in large size is in communication with the bottom end of the vibration box 31, and the other end of the soft connection 331 in small size is in communication with the air outlet of the blower 33, that is, the wind blown by the blower 33 can be blown to the grid plate 311 through the soft connection 331; it should be noted that since the vibration box 31 is inclined, the grid plate 311 is also inclined, so when the wind blown by the blower 33 through the soft connection 331 acts on the material on the grid plate 311, it can make the light and medium specific gravity material blow up and deviate to the low end of the grid plate 311.

[0022] The two sides of the vibration box 31 are respectively connected with a plurality of rib plates 315, the other end of the rib plate 315 is fixedly connected to the mounting frame 1, and the rib plate 315 is made of a metal material with elasticity, that is, the rib plate 315 can produce a certain deformation displacement to cooperate with the vibration displacement of the vibration box 31.

[0023] The vibration box 31 is also connected with a vibration mechanism, the vibration mechanism comprises a driving device 316, the driving device 316 is selected from a motor, the mounting frame 1 is also rotatably connected with a rotating shaft 317, the rotating shaft 317 is arranged below the vibration box 31, the driving device 316 is connected with the rotating shaft 317 through a belt and a pulley, thereby achieving the purpose of driving the rotating shaft 317 to rotate; the rotating shaft 317 is provided with two eccentric wheels 3171; the vibration box 31 is rotatably connected with a transmission rod 318, the transmission rod 318 is provided with two, the two transmission rods 318 are respectively arranged on the two sides of the vibration box 31, the mounting frame 1 is fixedly connected with a guide ring corresponding to the transmission rod 318, the transmission rod 318 is sleeved in the guide ring, one end of the transmission rod 318 close to the rotating shaft 317 abuts against the eccentric wheel 3171, the rotation of the eccentric wheel 3171 can push the transmission rod 318 to do reciprocating motion, thereby realizing the transmission of power to the vibration box 31, achieving the vibration effect of the vibration box 31, that is, when the eccentric wheel 3171 pushes the transmission rod 318 to move away from the eccentric wheel 3171, the vibration box 31 will move accordingly, at this time the rib plate 315 will deform, and when the eccentric wheel 3171 rotates to the maximum pushing position, the vibration box 31 will move back to the original position under the action of the elastic force of the rib plate 315, thereby realizing the purpose of vibration through the quick cooperation of pushing and resetting.

[0024] It should be noted that the transmission rod 318 is also inclined, and is arranged at the same inclination angle as the vibration box 31, so that the vibration box 31 can produce an impact force obliquely upward, and the oblique impact can be decomposed into a vertical component force and a horizontal component force, the vertical component force can throw the material on the grid plate 311 upward, and the horizontal component force can make the material move forward, so that the material on the grid plate 311 can achieve the purpose of climbing.

[0025] The air flow fine separator comprises a centrifugal suction fan 32 fixedly connected to the mounting frame 1. The centrifugal suction fan 32 can also generate a centrifugal suction force. The suction port of the centrifugal suction fan 32 is communicated with a bifurcated pipeline, i.e. two suction channels, which are symmetrically arranged about the discharge port. The two suction channels are commonly communicated with a protective cover 321 arranged in a triangular shape matching the vibration box 31. The protective cover 321 is arranged above the vibration box 31, i.e. can completely cover the upper part of the vibration box 31, so as to avoid that the material is blown by the blower 33 to the outside.

[0026] A square hole is formed in the protective cover 321 corresponding to the discharge port. The square hole matches the discharge port. The material leaked from the discharge port can fall onto the grid plate 311 through the square hole.

[0027] It should be noted that the suction force of the air flow coarse separator 2 is smaller than that of the air flow fine separator.

[0028] Working process: The crushed material is first coarsely separated by the air flow coarse separator 2 with small suction force. Since the air flow coarse separator has small suction force, it can separate the light specific gravity material in the material. Since the suction force is small, the waste material separated by the air flow coarse separator will not carry out aluminum scraps and light and thin aluminum sheets.

[0029] The material after coarse separation will fall onto the grid plate 311. Under the action of the blower 33, the light and medium material will be blown up and deviated to the low end of the grid plate 311. The light and medium specific gravity material will contain light specific gravity waste material and aluminum scraps and light and thin aluminum sheets. The light and medium specific gravity material blown up will be subjected to the suction force of the air flow fine separator. The suction force of the air flow fine separator is the same as that of the existing regenerated aluminum crushed material air flow separator. The light and medium specific gravity material in the suspended state will be subjected to the suction force of the air flow fine separator. Since the gravity of the aluminum scraps and light and thin aluminum sheets will be slightly greater than that of the waste material, the aluminum scraps and light and thin aluminum sheets in the suspended state will not be sucked away by the air flow fine separator, and the waste material will be sucked away by the air flow fine separator and discharged from the outlet.

[0030] The aluminum scraps and light and thin aluminum sheets not sucked away will be gathered at the small material outlet 312 due to the upward and low-end deviated blowing force of the grid plate 311. With the increase of the gathering amount, they will be gradually discharged from the small material outlet 312. The aluminum material with large specific gravity will not be blown up due to large gravity, and will always be on the grid plate 311. Under the action of the vibration force of the grid plate 311, it will produce a climbing displacement upward, and will be moved to the large material outlet 313 to be discharged.

[0031] Therefore, under the action of the blower 33 and the vibration box 31, the fine separation of the aluminum material is realized.

[0032] In summary, the utility model discloses the cooperation of air blower 33 and airflow concentrator, can make the light medium specific gravity material on the climbing vibrator separate when being in the suspended state, namely, air blower 33 can blow up the light heavy specific gravity material on the climbing vibrator, then under the cooperation of airflow concentrator, light specific gravity plastic and other waste materials can be directly sucked, and medium specific gravity aluminum scrap and light aluminum sheet can be gathered to the low end of climbing vibrator under the action of air blower 33 and gravity, and then are discharged by small material outlet 312, further avoid part aluminum scrap and light aluminum sheet to be sorted with plastic, and the heavy specific gravity material on the climbing vibrator will not be blown up by air blower 33, so it will be subjected to the climbing motion upward under the vibration of climbing vibrator, and then is discharged by large material outlet 313, realize the further subdivision of material.
