Description

Technical Field

[0001] The invention relates to the field of integrated circuit board metal recovery, in particular to an integrated circuit board metal recovery device. Background Art

[0002] Integrated circuit board is a carrier for loading integrated circuits. But when we say integrated circuit board, we also mean integrated circuit. Integrated circuit board is mainly made of silica gel, so it is generally green. Integrated circuit board adopts semiconductor manufacturing technology, and many transistors, resistors, capacitors and other components are made on a small single crystal silicon wafer, and the components are combined into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. Integrated circuit board also contains more metals. The metal content of integrated circuit board is as high as 40%, the most of which is copper, in addition to gold, aluminum, nickel, lead, silicon metal, etc., and the metal content of rich ore in nature is only 3% to 5%, so it is necessary to recycle the metals in waste integrated circuit boards.

[0003] In the process of recycling integrated circuit boards, the integrated circuit boards must first be crushed by crushing equipment, and the crushed integrated circuit boards must be ground into powder by grinding equipment. The mixed powder of the integrated circuit boards is then added to an electrostatic separator for sorting, and the mixed powder of the integrated circuit boards is evenly fed to a charged roller through an electric vibration feeder. The metal in the mixed powder of the integrated circuit boards is a conductor, and obtains a large amount of charge of the same sign from the roller electrode, so it is repelled by the roller electrode and falls into the aluminum collection tank. The non-metallic powder is a non-conductor, and is polarized by contact with the charged roller, generating an opposite bound charge near one end of the roller, which is sucked by the roller, carried to the back by the roller, and forced to fall into the glass collection tank by the brush, thereby recycling the metal in the mixed powder of the integrated circuit boards.

[0004] During the use of the electrostatic separator, the humidity of the external environment and the mixed powder has a great influence on the metal separation. When the humidity of the external environment and the mixed powder is too high, the water content in the mixed powder increases, and water has a conductive effect. When the moisture content of the silica gel powder in the mixed powder is high, the moisture in the silica gel powder is energized and discharges the electricity to the ground through the grounded rotating roller, and obtains the same sign of charge from the roller electrode, which causes repulsion with the roller, causing the silica gel powder to follow the metal into the conductor collection box, resulting in too much silica gel powder mixed in the separated metal. Based on the above problems, the present application proposes an integrated circuit board metal recovery device. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an integrated circuit board metal recovery device, which has the advantages of dehumidifying the inside of the electrostatic separator and dehumidifying the integrated circuit board powder, thereby solving a series of problems such as unclean metal separation in the integrated circuit board caused by humidity.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an integrated circuit board metal recovery device.

[0035] Example 1: In a typical implementation of the present application, Figure 1-4 As shown, an integrated circuit board metal recovery device comprises a separation box 1, an electric vibrating feeder 2 is fixedly arranged inside the separation box 1, a discharge hopper 7 is fixedly arranged on the lower side wall of the separation box 1, and the number of the discharge hoppers 7 is two, the discharge hopper 7 on the right is a metal discharge hopper, and the discharge hopper 7 on the left is a non-metal discharge hopper. Through the left and right discharge hoppers 7, it is convenient to classify and place the separated metal and silica gel powder, thereby preventing the separated silica gel powder from being mixed into the metal powder again;

[0036] A metal separation component 3, which is installed inside the separation box 1 and is used for metal separation;

[0037] A hot air conveying component 4 is installed on the separation box 1 and is used to convey hot air to the inside of the separation box 1. The hot air conveying component 4 includes a hot air blower 41 installed on the left side of the separation box 1. A filter screen 42 is fixedly provided at the air inlet of the hot air blower 41. A connecting pipe 44 is fixedly provided at the air outlet of the hot air blower 41. A diverter box 43 is fixedly provided at the right end of the connecting pipe 44. Air outlet pipes 45 are fixedly provided on both the upper and lower sides of the diverter box 43. The number of the air outlet pipes 45 is several, and the several air outlet pipes 45 are symmetrically distributed. The air outlet pipes 45 are inclinedly arranged. The inclined air outlet pipes 45 prevent the internal hot air entering the separation box 1 from directly blowing onto the separated silicone grease powder and metal powder, and prevent the silicone grease powder from being mixed into the metal powder under the influence of wind force;

[0038] A hot air delivery duct 5 is installed on the top of the separation box 1 for delivering hot air. The hot air delivery duct 5 comprises an air inlet duct 51 fixedly arranged on the top of the separation box 1. A filter box 52 is fixedly arranged on the top of the air inlet duct 51. An activated carbon filter screen 53 is fixedly arranged inside the filter box 52. A connecting elbow 54 is fixedly arranged on the top of the filter box 52. An insulation layer is fixedly arranged on the outer surfaces of the air inlet duct 51 and the connecting elbow 54. The insulation layer is an insulation sponge. The air inlet duct 51 and the connecting elbow 54 are stainless steel pipes. The insulation layer made of insulation sponge can prevent the influence of the external environment on the hot air, thereby avoiding the heat in the hot air from being conducted to the external environment through the air inlet duct 51 and the connecting elbow 54. The air outlet end of the connecting elbow 54 is fixedly provided with an air filter. An air outlet hood 55 is provided, and an air supply pipe 56 is fixedly provided at the bottom of the air outlet hood 55. The hot air blower 41 conveys the hot air to the inside of the diverter box 43 through the connecting pipe 44, and enters the inside of the separation box 1 through the air outlet pipe 45, heats and evaporates the moisture inside the separation box 1, and drives the evaporated moisture to enter the filter box 52 through the air inlet pipe 51. The hot air filtered and dehumidified by the activated carbon filter 53 enters the air outlet hood 55 through the connecting elbow 54, and enters the inside of the mixed powder conveying component 6 through the obliquely arranged air supply pipe 56, so as to dry and dehumidify the mixed powder of the integrated circuit board inside the mixed powder conveying component 6, so as to ensure the drying of the separation box 1 and the drying of the mixed materials, and avoid the influence of excessive moisture on the metal separation in the integrated circuit board;

[0039] It is worth mentioning that the electric vibration feeder 2 mentioned above is mainly composed of a vibration frame, a vibration motor, a spring, a support seat and a wear-resistant lining. Due to the start of the vibration motor, the frame is forced to vibrate on the support spring, and the material uses this vibration as a power to slide and throw on the trough, so that the material moves forward to achieve feeding. Therefore, the electric vibration feeder 2 is an existing mature technical structure, so the present invention will not be described in detail;

[0040] The mixed powder conveying component 6 is fixedly installed on the top of the separation box 1, and is used to convey the mixed powder after the metal of the integrated circuit board is crushed and ground. The mixed powder conveying component 6 is convenient for conveying the mixed powder of the integrated circuit board and for breaking up the agglomerated mixed powder, thereby ensuring that the mixed powder of the integrated circuit board enters the separation box 1 evenly.

[0041] As a preferred implementation in this embodiment, refer to Figure 5-7The mixed powder conveying component 6 includes a mounting frame 61 fixedly arranged on the top of the separation box 1, a feeding bin 62 with a moisture outlet hole is fixedly arranged inside the mounting frame 61, an air supply pipe 56 is fixedly arranged on the top of the feeding bin 62, a rotating motor 63 is fixedly arranged on the right side of the feeding bin 62, a feeding screw 64 is fixedly arranged on the output end of the rotating motor 63, the feeding screw 64 is located inside the feeding bin 62, a discharge pipe 65 is fixedly arranged at the bottom of the feeding bin 62, a crushing type unloading component 66 is arranged on the top of the feeding bin 62, and the crushing type unloading component 66 includes a unloading hopper 661 fixedly arranged on the top of the feeding bin 62, a main dispersing knife 662 and a secondary dispersing knife 665 are rotatably arranged inside the unloading hopper 661, a driving gear 663 is fixedly arranged on the left end of the main dispersing knife 662, a driven gear 664 is meshed on the surface of the driving gear 663, the driven gear 664 is fixedly arranged on the left end of the secondary dispersing knife 665, and a slave transmission wheel 66 is fixedly arranged on the right end of the main dispersing knife 662 6. A transmission belt 667 is meshed inside the pulverizing unloading member 66, and a main transmission wheel 668 is meshed inside the transmission belt 667. The main transmission wheel 668 is fixedly installed on the right end of the feeding screw 64, and the feeding screw 64 is driven to rotate by the rotating motor 63, so that the feeding screw 64 drives the mixed powder of the integrated circuit board to move, and the mixed powder will continue to turn under the push of the feeding screw 64, which can avoid the accumulation of mixed powder and the inability of the interior to contact with hot air, and avoid the occurrence of a part of the mixed powder that is not completely dried entering the separation box 1. Secondly, the feeding screw 64 drives the main dispersing knife 662 to rotate through the main transmission wheel 668, the transmission belt 667 and the slave transmission wheel 666, and the main dispersing knife 662 drives the auxiliary dispersing knife 665 to rotate through the active gear 663 and the passive gear 664, so as to break up the mixed powder that has condensed into blocks, so that the hot air can dry the mixed powder, and the broken mixed powder can evenly enter the separation box 1.

[0042] As a preferred implementation in this embodiment, refer to Figure 8The metal separation component 3 includes a driving motor 31 fixedly arranged on the front side of the separation box 1, a grounded rotating roller 32 is fixedly arranged at the output end of the driving motor 31, a scraper brush 33 is overlapped on the left side of the grounded rotating roller 32, and the scraper brush 33 is fixedly installed inside the separation box 1, an electrode rod 34 is arranged on the right side of the grounded rotating roller 32, and high-voltage insulators 35 are fixedly arranged at both ends of the electrode rod 34, and the high-voltage insulator 35 is fixedly installed on the right side wall of the separation box 1. The electrode rod 34 is energized by an external high-voltage power supply, so that high-voltage static electricity is generated inside the separation box 1, and the metal powder in the mixed powder obtains a charge of the same sign on the grounded rotating roller 32. Therefore, repulsion occurs between the metal powder and the grounded rotating roller 32, and enters the right side of the discharge hopper 7 under the gravity of the metal powder itself and the rotational inertia of the grounded rotating roller 32, while the silica gel powder contacts the charged grounded rotating roller 32 and is polarized to generate opposite bound charges, and is carried to the back by the grounded rotating roller 32 and is forced to be brushed down by the scraper brush 33 into the left side of the discharge hopper 7.

[0043] Example 2: Please refer to Figure 9-10 The difference between this embodiment and the above embodiment is that a movable plate 57 is overlapped inside the filter box 52, a T-shaped plug plate 58 is slidably arranged inside the movable plate 57, an activated carbon filter 53 is fixedly arranged on the rear side of the T-shaped plug plate 58, a rotating plate 59 is rotatably arranged on the front side of the movable plate 57, an L-shaped locking plate 510 is overlapped on the surface of the rotating plate 59, and the L-shaped locking plate 510 is fixedly installed on the front side of the filter box 52. When the activated carbon filter 53 absorbs too much moisture inside, the rotating plate 59 is moved from the L-shaped locking plate 510 to the L-shaped locking plate 510. The plate 510 is taken out, and the handle on the movable plate 57 is pulled. The movable plate 57 drives the activated carbon filter 53 to be moved out of the filter box 52 through the T-shaped plug plate 58. The activated carbon filter 53 is pulled to drive the T-shaped plug plate 58 to be moved out of the movable plate 57, and the replaced activated carbon filter 53 is inserted into the movable plate 57 through the T-shaped plug plate 58. The movable plate 57 inserts the replaced activated carbon filter 53 into the filter box 52 through the T-shaped plug plate 58, and the rotating plate 59 is rotated into the L-shaped locking plate 510.

[0044] Working principle of the present invention: when in use, start the hot air blower 41, draw in external air through the hot air blower 41 and heat it, the heated air enters the inside of the diversion box 43 through the connecting pipe 44, and is blown to the inside of the separation box 1 through the air outlet pipe 45, the moisture in the separation box 1 is heated by the hot air, so that the moisture evaporates and flows upward, the hot air drives the evaporated moisture to enter the inside of the filter box 52 through the air inlet pipe 51, and the moisture in the hot air is filtered through the activated carbon filter 53, the moisture in the hot air is removed through the activated carbon filter 53, the hot air after the moisture is removed enters the inside of the air outlet hood 55 through the connecting elbow 54 for diversion, and enters the inside of the feeding bin 62 through the air supply pipe 56;

[0045] The broken and ground integrated circuit board powder is added into the lower hopper 661, and the feeding screw 64 is driven by the output end of the rotating motor 63 to rotate, and the main transmission wheel 668 is driven by the feeding screw 64 to rotate, so that the main transmission wheel 668 drives the slave transmission wheel 666 to rotate through the transmission belt 667, and the slave transmission wheel 666 drives the main dispersion knife 662 to rotate, and the main dispersion knife 662 drives the driven gear 664 to rotate through the driving gear 663, and drives the auxiliary dispersion knife 665 to rotate through the driven gear 664, and the feeding The blocky integrated circuit board mixed powder entering the lower hopper 661 is broken up, and the broken up mixed powder enters the inside of the feeding bin 62 through the lower hopper 661, and is transported by the feeding screw 64. During the transportation process, the hot air entering the feeding bin 62 blows toward the mixed powder to heat the mixed powder, so that the moisture in the mixed powder evaporates. Since the hot air enters the feeding bin 62 obliquely, it pushes the evaporated moisture to move to the right side of the feeding bin 62 and is discharged through the moisture outlet hole on the feeding bin 62.

[0046] When the feeding screw 64 conveys the dried post-mixed powder to the left side of the feeding bin 62, the mixed powder will enter the discharge pipe 65 and enter the electric vibration feeder 2 in the separation box 1 through the discharge pipe 65. The electric vibration feeder 2 vibrates the mixed powder and feeds it, so that the mixed powder falls evenly onto the grounded rotating roller 32, and the electrode rod 34 is energized to generate high-voltage static electricity inside the separation box 1. The metal powder in the mixed powder obtains an electric charge of the same sign on the grounded rotating roller 32, so there is repulsion between the metal powder and the grounded rotating roller 32, and the gravity of the metal powder itself and the rotational inertia of the grounded rotating roller 32 make the metal powder enter the discharge hopper 7 on the right. The silica gel powder in the mixed powder is a non-conductor, and is polarized by contact with the charged grounded rotating roller 32, and generates an opposite bound charge at one end close to the grounded rotating roller 32, which is sucked by the grounded rotating roller 32, and is carried to the back by the grounded rotating roller 32 and forced to be brushed by the scraper brush 33 into the discharge hopper 7 on the left.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
