Description

Technical Field

[0001] This invention relates to an extraction device, and more particularly to a metal extraction device for recycling waste lithium batteries. Background Technology

[0002] Used lithium batteries contain various valuable metals such as cobalt, copper, nickel, aluminum, and iron. Improper disposal not only wastes resources but also pollutes the environment. Currently, most people first crush used lithium-ion batteries and then extract the metals for recycling.

[0003] Patent publication number CN207124268U discloses a high-efficiency sorting and recycling device for waste lithium batteries, including a support frame. A crusher is installed on the top of the support frame. The output shaft of the crusher motor is rotatably connected to one end of the crusher roller in the inner cavity of the crusher via a belt. The crusher has a feed inlet at the top and a discharge pipe at the bottom. The upper end of the discharge pipe is connected to the discharge outlet of the crusher, and the lower end is connected to a screen. The output shaft of the vibration motor is vibratingly connected to the screen in the inner cavity of the screen.

A discharge plate is installed on the outside of the bottom front end of the support frame, in front of the magnetic roller. Although the aforementioned patent can recycle the metals inside waste lithium batteries, the sieve separates the broken lithium-ion battery fragments, resulting in the simultaneous screening of metal or non-metal substances of equal volume, which requires secondary screening and is quite troublesome.

[0004] Based on the deficiencies in the aforementioned patents, there is a need to design a metal extraction device for recycling waste lithium batteries that can fully extract metals from lithium-ion battery debris and avoid secondary screening. Summary of the Invention

[0012] As a preferred embodiment of the present invention, it further includes a vibrating mechanism for agitating lithium battery debris. The vibrating mechanism includes a short drive shaft, a cam with a column, a hinged connecting rod, a positioning crossbar, a vibrating cross plate, vibrating columns, and buffer springs.

A columnar sliding shaft is provided at the lower part of the cam with a column. The positioning crossbar is slidably mounted in the middle of the right side of the sealed bottom box.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The present invention uses an adsorption magnetic plate to adsorb the metal material in lithium battery debris onto a first conveyor belt assembly. The first conveyor belt assembly discharges the metal material through a left discharge pipe, while the second conveyor belt assembly reverses and discharges the non-metallic material through a right discharge pipe. A cleaning brush plate can easily scrape the material off the first or second conveyor belt assembly to avoid affecting the extraction effect. In this way, the metal substances in lithium-ion battery debris can be fully extracted, avoiding secondary screening.

[0018] 2. Under the action of the vibrating material mechanism, the four vibrating columns move up and down to strike the belt of the second conveyor belt assembly. The buffer spring plays a buffering role, thereby causing the lithium battery debris to vibrate and separate, which makes it easier for the subsequent magnetic adsorption plate to better adsorb the metal material. In this way, the lithium battery debris can be vibrated and separated, which makes it easier for the magnetic adsorption plate to adsorb the metal material.

[0019] 3. Under the action of the blowing mechanism, the limit horizontal axis reverses and drives the guide fan to reverse. The reversed guide fan blows air onto the first conveyor belt assembly through the air duct, thereby blowing away non-metallic impurities on the first conveyor belt assembly. This prevents some non-metallic impurities from adhering to the first conveyor belt assembly and affecting the subsequent processing of metal materials. In this way, non-metallic impurities on the first conveyor belt assembly can be easily blown away. Attached Figure Description

Detailed Implementation

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0037] Example 1

[0038] A metal extraction device for recycling waste lithium batteries, such as Figures 1-6 As shown, the device includes a sealed bottom box 1, a support frame 2, a material conveying mechanism 3, a discharge pipe 5, a cleaning brush plate 6, an adsorption magnetic plate 7, a drive mechanism 8, and a feeding mechanism 9. The support frame 2 is symmetrically fixed to the lower part of the sealed bottom box 1. Two discharge pipes 5 are fixed to the left side of the sealed bottom box 1. A cleaning brush plate 6 is fixed to the left side of each of the two discharge pipes 5. An adsorption magnetic plate 7 is fixed to the upper part of the sealed bottom box 1. The material conveying mechanism 3 is provided on the sealed bottom box 1, which can realize the transportation of lithium battery debris. The drive mechanism 8 is also provided on the sealed bottom box 1, which provides power to the material conveying mechanism 3. The feeding mechanism 9 is provided on the sealed bottom box 1, which can realize the feeding of crushed lithium battery debris.

[0039] like Figure 3 and Figure 4As shown, the material conveying mechanism 3 includes a first material conveying belt assembly 31, a first positioning horizontal shaft 32, a second material conveying belt assembly 33, and a second positioning horizontal shaft 34. The first positioning horizontal shaft 32 is symmetrically rotated on the upper part of the sealed bottom box 1. The first material conveying belt assembly 31 is connected between the first positioning horizontal shafts 32 on the left and right sides. The first material conveying belt assembly 31 consists of two synchronous pulleys and a belt. The synchronous pulleys are all installed on the first positioning horizontal shaft 32, and the belt is wound between the two synchronous pulleys. The right side of the sealed bottom box 1 is rotatably provided with four second positioning horizontal shafts 34. The second material conveying belt assembly 33 is connected between the four second positioning horizontal shafts 34. The second material conveying belt assembly 33 consists of four synchronous pulleys and a belt. The synchronous pulleys are all installed on the second positioning horizontal shaft 34, and the belt is wound between the four synchronous pulleys. Two cleaning brush plates 6 are in contact with the first material conveying belt assembly 31 and the second material conveying belt assembly 33 respectively. The adsorption magnetic plate 7 is located inside the belt of the first material conveying belt assembly 31.

[0040] like Figure 3 and Figure 5 As shown, the drive mechanism 8 includes a servo motor 81, a fixed frame 82, a worm gear 83, and a worm wheel 84. The servo motor 81 is fixedly connected to the upper right side of the outer front side of the sealed base box 1. The fixed frame 82 is fixedly connected to the upper middle part of the outer front side of the sealed base box 1. The worm gear 83 is rotatably installed inside the fixed frame 82. The worm gear 83 is fixedly connected to the output shaft of the servo motor 81. The worm wheel 84 is fixedly connected to the front of the first positioning horizontal shaft 32 on the right. The worm wheel 84 is also fixedly connected to the front of the second positioning horizontal shaft 34 on the upper left. Both worm wheels 84 mesh with the worm gear 83.

[0041] like Figure 3 and Figure 6 As shown, the feeding mechanism 9 includes a storage box 91, a distribution guide plate 92, and a height limiting plate 93. The storage box 91 is fixedly connected to the upper part of the outer right side of the sealed bottom box 1. The distribution guide plate 92 is fixedly connected to the upper right side of the sealed bottom box 1. The distribution guide plate 92 is connected to the storage box 91. The height limiting plate 93 is fixedly connected to the lower part of the outer left wall of the distribution guide plate 92.

[0042] First, the operator places two collection containers directly below the two discharge pipes 5, then pours the crushed lithium battery fragments into the storage bin 91. The lithium battery fragments fall evenly onto the second conveyor belt assembly 33 via the distribution guide plate 92. The height-limiting baffle 93 prevents the fragments from splashing. The servo motor 81 is started, driving the worm gear 83 to rotate. The rotation of the worm gear 83 drives the second positioning horizontal shaft 34 on the upper left to reverse through the left worm wheel 84. Thus, the four second positioning horizontal shafts 34 reverse in coordination, driving the second conveyor belt assembly 33 to reverse. The reverse rotation of the second conveyor belt assembly 33 causes the lithium battery fragments to move to the left. The leftward movement of the lithium battery fragments corresponds to the adsorption magnetic plate 7, and the metal material in the lithium battery fragments is adsorbed onto the first conveyor belt assembly 31. At the same time, the rotation of the worm gear 83 drives the right worm wheel... 84 drives the right first positioning horizontal axis 32 to rotate clockwise, thereby coordinating the clockwise rotation of the left and right first positioning horizontal axes 32 to drive the first conveyor belt assembly 31 to rotate clockwise. The clockwise rotation of the first conveyor belt assembly 31 drives the metal material to move to the left. The metal material moves to the left and falls into the collection container through the left discharge pipe 5. Meanwhile, the second conveyor belt assembly 33 reverses and drives the non-metallic material to move to the left and also falls into the collection container through the right discharge pipe 5. The cleaning brush plate 6 can easily scrape the material off the first conveyor belt assembly 31 or the second conveyor belt assembly 33 to avoid affecting the extraction effect. After all the lithium battery residue metal is extracted, the servo motor 81 is turned off, and both the first conveyor belt assembly 31 and the second conveyor belt assembly 33 stop rotating. Then, the collection containers are picked up separately to carry out subsequent processing of the metal and non-metal materials.

[0043] Example 2

[0044] Based on Example 1, such as Figures 7-9 As shown, it also includes a vibrating mechanism 10, which includes a short drive shaft 101, a cam with a column 102, a hinged connecting rod 103, a positioning crossbar 104, a vibrating crossbar 105, a vibrating column 106, and a buffer spring 107. The short drive shaft 101 is rotatably mounted on the lower right side of the rear of the sealed base box 1. The short drive shaft 101 is connected to the second positioning crossbar 34 on the upper left side via a synchronous belt. The cam with a column 102 is fixedly connected to the front of the short drive shaft 101. 2. A columnar sliding shaft is provided at the lower part. A positioning crossbar 104 is slidably provided in the middle of the right side of the sealed bottom box 1. A hinged connecting rod 103 is rotatably provided in the middle of the rear part of the positioning crossbar 104. The hinged connecting rod 103 is rotatably connected to the columnar sliding shaft with column cam 102. A vibrating crossbar 105 is fixedly connected in the middle of the positioning crossbar 104. Four vibrating columns 106 are slidably provided on the vibrating crossbar 105 at intervals. A buffer spring 107 is connected between each of the four vibrating columns 106 and the vibrating crossbar 105.

[0045] like Figure 7 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes a blowing mechanism 11, which includes an air guide hood 111, a dustproof plate 112, a guide fan 113, a limiting horizontal shaft 114, an air guide pipe 115, and a positioning frame 116. The air guide hood 111 is embedded in the upper left side of the rear of the sealed base box 1. The dustproof plate 112 is fixedly connected to the air guide hood 111. The limiting horizontal shaft 114 is rotatably provided in the middle of the air guide hood 111. The second positioning horizontal shaft 34 in the lower left is connected to the limiting horizontal shaft 114 by a synchronous belt drive. The guide fan 113 is fixedly connected in the middle of the limiting horizontal shaft 114. The guide fan 113 is located inside the air guide hood 111. The positioning frames 116 are fixedly connected to the upper left side of both the front and rear sides of the sealed base box 1. The air guide pipe 115 is fixedly connected between the positioning frames 116 on the front and rear sides. The air guide pipe 115 is connected to the air guide hood 111.

[0046] When the servo motor 81 is working, the second positioning horizontal shaft 34 on the upper left drives the short shaft 101 to reverse through the synchronous belt drive. The reverse rotation of the short shaft 101 drives the column cam 102 to reverse, and the reverse rotation of the column cam 102 drives the hinged connecting rod 103 to move up and down. The up and down movement of the hinged connecting rod 103 drives the vibrating horizontal plate 105 to move up and down. The up and down movement of the vibrating horizontal plate 105 drives the four vibrating columns 106 to move up and down. The up and down movement of the four vibrating columns 106 knocks on the belt of the second conveyor belt assembly 33. The buffer spring 107 plays a buffering role, thereby causing the lithium battery debris to vibrate and separate, which makes it easier for the subsequent adsorption magnetic plate 7 to better adsorb the metal material. After all the lithium battery debris metal is extracted, the servo motor 81 is turned off, the second positioning horizontal shaft 34 on the upper left stops driving the short shaft 101 to reverse through the synchronous belt drive, and the four vibrating columns 106 also stop moving up and down. In this way, the lithium battery debris can be vibrated and separated, which makes it easier for the adsorption magnetic plate 7 to adsorb the metal material.

[0047] When the servo motor 81 is working, the lower left second positioning horizontal axis 34 drives the limiting horizontal axis 114 to reverse through the synchronous belt drive. The reverse rotation of the limiting horizontal axis 114 drives the guide fan 113 to reverse. The reverse rotation of the guide fan 113 blows air onto the first conveyor belt assembly 31 through the air duct 115, thereby blowing away non-metallic impurities on the first conveyor belt assembly 31. This prevents non-metallic impurities from adhering to the first conveyor belt assembly 31 and affecting the subsequent processing of metal materials. After all the lithium battery residue metal is extracted, the servo motor 81 is turned off, the lower left second positioning horizontal axis 34 stops driving the limiting horizontal axis 114 to reverse through the synchronous belt drive, and the guide fan 113 also stops reversing. In this way, it is convenient to blow away non-metallic impurities on the first conveyor belt assembly 31.

[0048] Example 3

[0049] Based on Examples 1 and 2, such as Figure 13 and Figure 14As shown, it also includes a limiting mechanism 12, which includes a limiting plate 121 and a limiting spring 122. The upper right side of both the front and rear sides of the sealed bottom box 1 is slidably provided with the limiting plate 121. The limiting plate 121 can prevent lithium battery debris from falling from the second conveyor belt assembly 33. The limiting plates 121 on both the front and rear sides are evenly spaced with the limiting spring 122 connected to the sealed bottom box 1.

[0050] like Figure 13 and Figure 15 As shown, it also includes a feeding mechanism 13, which includes a transmission horizontal shaft 131 and a feeding roller 132. The lower part of the storage box 91 is rotatably provided with the transmission horizontal shaft 131, and the feeding roller 132 is fixedly connected to the middle of the transmission horizontal shaft 131. The feeding roller 132 can realize auxiliary feeding of lithium battery debris. The transmission horizontal shaft 131 and the second positioning horizontal shaft 34 on the upper right are driven by a synchronous belt.

[0051] When the second conveyor belt assembly 33 reverses to transport lithium battery debris, the front and rear limit plates 121 limit the belt edge of the second conveyor belt assembly 33, and the limit spring 122 acts as a buffer to prevent the belt of the second conveyor belt assembly 33 from vibrating too much, which could cause the lithium battery debris to fall off accidentally. This can prevent the lithium battery debris from falling off accidentally and affecting subsequent extraction.

[0052] When the servo motor 81 is working, the second positioning horizontal shaft 34 on the upper right drives the transmission horizontal shaft 131 to reverse through the synchronous belt drive. The reverse rotation of the transmission horizontal shaft 131 drives the feeding roller 132 to reverse. The feeding roller 132 reverses and pushes the lithium battery debris in the storage box 91 downward to prevent the lithium battery debris from blocking the outlet of the storage box 91 and affecting subsequent work. After all the lithium battery debris metal is extracted, the servo motor 81 is turned off, the second positioning horizontal shaft 34 on the upper right stops driving the transmission horizontal shaft 131 to reverse through the synchronous belt drive, and the feeding roller 132 also stops reversing. In this way, it is convenient to assist in feeding the lithium battery debris.
