[0002] High-copper-content and high-purity copper solid waste, such as retired lithium battery copper foil and scrap copper enameled wire, is an important source of recycled copper. In traditional lithium batteries, the negative electrode foil is made of electrolytic copper, and its recycling process is relatively mature. However, with increasing demands for the safety and cost of lithium batteries, composite copper foil (copper content 60-80%) has been widely used. Composite copper foil is a new type of lithium battery current collector material made with PET, PP, and other polymer materials as the intermediate substrate and two layers of deposited metal. Meanwhile, copper enameled wire (copper content approximately 97.5%) is made by annealing and softening bare copper wire, followed by multiple coatings and baking.

[0032] Example 1 Reference Figures 1-8This is the first embodiment of the present invention, which provides an integrated treatment device for continuous pyrolysis, gasification and smelting of copper-containing solid waste, including a treatment component 100. In this embodiment, the treatment component 100 includes a pyrolysis chamber 101, a gasification chamber 102, a smelting chamber 103 and a cooling chamber 104.

The opening and closing door 401 is slidably connected to the door frame. Through the cooperation of the gear 307 and the rack 306 between the opening and closing door 401 and the door frame, the motor drives the gear 307 to rotate, thereby causing the rack 306 to slide. The rack 306 is connected to the opening and closing door 401, allowing the opening and closing door 401 to slide accordingly. The infrared sensing module 402 can detect whether there is material passing by. When material passes by, the motor is started and the opening and closing door 401 is opened.

[0036] Furthermore, the present invention also includes a conveying component 500, which is disposed within the processing component 100.

[0037] In this embodiment, the conveying assembly 500 includes a base plate 501 disposed at the lower end of the pyrolysis chamber 101 and the gasification chamber 102, and a transmission steel belt 502 disposed on the base plate 501. The transmission steel belt 502 is disposed on the base plate 501 and is composed of multiple steel plate units that are hinged end to end. The transmission steel belt 502 is configured as a conveyor belt and is wound into a ring. Multiple friction particles are disposed on the surface. A drive wheel is disposed inside the transmission steel belt 502. The drive wheel is driven by a motor, thereby driving the movement of the transmission steel belt 502.

[0038] In this embodiment, the feeding component 403 includes a storage bin 403a disposed on the pyrolysis chamber 101 and a feeding cylinder 403b disposed on the storage bin 403a. An electric control valve 309a is provided between the feeding cylinder 403b and the storage bin 403a, and an electric control valve 309a is also provided between the storage bin 403a and the pyrolysis chamber 101. The electric control valve 309a can be opened and closed to control the amount of raw material conveyed.

[0039] Furthermore, in this embodiment, the transmission component 200 includes a connecting sleeve 201 disposed between the gasification chamber 102 and the melting chamber 103. The connecting sleeve 201 is bent, and the lower end of the connecting sleeve 201 is connected to the upper end of the melting chamber 103. The connecting sleeve 201 includes a bent portion and a straight portion disposed at the lower end of the bent portion.

[0040] A transmission frame 202 is provided inside the connecting cover 201. The transmission frame 202 is located on the straight section and is connected by bolts. A receiving part 203 is provided on the transmission frame 202. The receiving part 203 is used to receive the solid material sent from the gasification chamber 102 and transfer it to the melting chamber 103.

[0041] In this embodiment, the receiving component 203 includes a first receiving cylinder 203a disposed on the transmission frame 202, a second receiving cylinder 203b corresponding to the first receiving cylinder 203a, and a gas discharge cylinder 203c disposed on the transmission frame 202. A rotating component 204 is provided between the first receiving cylinder 203a, the second receiving cylinder 203b, and the gas discharge cylinder 203c, and the rotating component 204 drives the movement of the first receiving cylinder 203a, the second receiving cylinder 203b, and the gas discharge cylinder 203c.

[0042] Furthermore, the first receiving cylinder 203a and the second receiving cylinder 203b are arranged opposite to each other, and two gas discharge cylinders 203c are provided and arranged opposite to each other. A transfer member 300 is provided between the first receiving cylinder 203a and the second receiving cylinder 203b.

[0043] In this embodiment, the rotating component 204 includes a rotating ring 204a rotatably connected to the transmission frame 202, a protruding ring 204b disposed on the rotating ring 204a, and a recessed groove 204c formed on the rotating ring 204a. Two protruding rings 204b are provided and arranged opposite each other. The two recessed grooves 204c are formed at two connecting points of the two protruding rings 204b, also opposite each other, and the protruding rings 204b and the recessed grooves 204c are smoothly connected. Abutment blocks 204d that abut against the surface of the rotating ring 204a are provided on the first receiving cylinder 203a, the second receiving cylinder 203b, and the gas discharge cylinder 203c. A guide rail 205 is provided for sliding the first receiving cylinder 203a, the second receiving cylinder 203b, and the gas discharge cylinder 203c. A pull rod 206 is provided between the abutting block 204d of the first receiving cylinder 203a and the abutting block 204d of the gas discharge cylinder 203c, and between the abutting block 204d of the second receiving cylinder 203b and the abutting block 204d of the gas discharge cylinder 203c. One end of each pull rod 206 is hinged to the abutting block 204d, and the other end of each pull rod 206 is provided with a sliding groove 207. A slider 208 that cooperates with the sliding groove 207 is provided on the abutting block 204d. At the same time, a spring is provided between the guide rail 205 and the abutting block 204d.

[0044] Because the abutment block 204d is always in contact with the surface of the rotating ring 204a, as the rotating ring 204a rotates, the abutment block 204d will continuously move to the protruding ring 204b and the recessed groove 204c. Since the recessed groove 204c and the protruding ring 204b are relatively positioned, two situations will occur when the rotating ring 204a rotates: First, the recessed groove 204c corresponds to the first receiving cylinder 203a and the second receiving cylinder 203b. At this time, the first receiving cylinder 203a and the second receiving cylinder 203b are in a position close to each other, while the two gas discharge cylinders 203c, which correspond to the protruding ring 204b, are pushed away to a position far from each other. At this time, the raw material in the first receiving cylinder 203a is... The material is fed into the second receiving cylinder 203b; secondly, the protruding ring 204b corresponds to the first receiving cylinder 203a and the second receiving cylinder 203b. At this time, the first receiving cylinder 203a and the second receiving cylinder 203b are in a position far apart from each other. The first receiving cylinder 203a is used to continue to receive the raw material above, while the second receiving cylinder 203b transports the raw material downward. At this time, the two gas discharge cylinders 203c correspond to the recessed groove 204c and are pushed away to a position close to each other. This gas discharge cylinder 203c is connected to the first receiving cylinder 203a and extracts some of the gas in the first receiving cylinder 203a to the outside, or adds high-heat gas or catalyst to keep the raw material in the first receiving cylinder 203a warm.

[0045] Furthermore, in this embodiment, the transmission member 300 includes an insertion groove 301 disposed on the first receiving cylinder 203a, an insertion cylinder 302 disposed on the upper end of the second receiving cylinder 203b and cooperating with the insertion groove 301, an intermediate ring 303 disposed on the upper end of the insertion cylinder 302, a mounting ring 304 disposed on the intermediate ring 303, and a clamping rod 305 disposed between every two adjacent mounting rings 304. Both ends of the clamping rod 305 are connected to the mounting rings 304. The center position of the clamping rod 305 is set in an arc shape. A rack 306 is provided in the insertion groove 301. A gear 307 is provided on one of the mounting rings 304. When one of the mounting rings 304 rotates, the clamping rod 305 will drive the adjacent mounting rings 304 to rotate synchronously, thereby driving multiple clamping rods 305 to rotate inward or outward together.

[0046] Preferably, each clamping rod 305 is provided with a fan-shaped support plate 305a, and a toggle plate 305b is provided on the clamping rod 305. Multiple closing plates 305c are rotatably connected in the opening at the lower end of the first receiving cylinder 203a. In the initial state, the lower ends of the multiple closing plates 305c are close to each other, and the protruding part on the inner side of the closing plate 305c is used to close the plate, preventing solid raw materials from falling. A protruding ring extends from the lower end of each closing plate 305c, and the protruding ring forms a circular opening.

[0047] Furthermore, in the initial state, the upper ends of the multiple actuating plates 305b are close to each other, and the size of the protrusion formed at the upper end is smaller than the size of the circular opening formed by the protruding ring. When the insertion cylinder 302 is inserted into the insertion groove 301, the upper ends of the multiple actuating plates 305b are inserted into the circular opening formed by the protruding ring. Due to the action of the rack 306 and the gear 307, the clamping rod 305 rotates, thereby causing the multiple actuating plates 305b to change from a close-to-each-other state to a far-from-each-other state. Since the actuating plates 305b correspond one-to-one with the closing plates 305c, the rotation of the actuating plates 305b will drive the rotation of the closing plates 305c, thereby exposing the lower opening of the first receiving cylinder 203a, allowing the solid raw material to fall.

[0048] Furthermore, a feeding and docking cylinder 308 is provided at one end of each of the two gas discharge cylinders 203c that are close to each other, and a docking cylinder 309 corresponding to the feeding and docking cylinder 308 is provided on the first receiving cylinder 203a, and an electric control valve 309a is provided on the feeding and docking cylinder 308.

[0049] Preferably, a stepper motor 204e is provided on the rotating ring 204a, and the electronic control program of the stepper motor 204e is connected to the opening and closing door 401 at the end of the gasification chamber 102.

[0050] Operation process: When the raw material is transported to the outside of the gasification chamber 102 by the transmission steel belt 502, the rotating ring 204a rotates under the action of the stepper motor 204e. After the opening and closing door 401 of the gasification chamber 102 is opened, the stepper motor 204e is turned on simultaneously and pushes the first receiving cylinder 203a upward, so that the upper end surface of the first receiving cylinder 203a is flush with the protruding position of the bent part. The raw material falls naturally from the bent part into the first receiving cylinder 203a. At the same time, the opening and closing door 401 is closed. When the first receiving cylinder 203a is being transported, no other raw material is sent out from the opening and closing door 401.

[0051] Then, the stepper motor 204e continues to drive the rotating ring 204a to rotate, so that the recessed groove 204c corresponds with the first receiving cylinder 203a and the second receiving cylinder 203b. At this time, the first receiving cylinder 203a and the second receiving cylinder 203b are in a position close to each other, while the two gas discharge cylinders 203c correspond to the protruding ring 204b and are pushed away to a position far apart from each other. At this time, the insertion cylinder 302 is inserted into the insertion groove 301, and the upper ends of the multiple actuating plates 305b form a circular opening. Due to the action of the rack 306 and the gear 307, the clamping rod 305 rotates, thereby changing the multiple actuating plates 305b from a state close to each other to a state far apart from each other. Since the actuating plates 305b correspond one-to-one with the closing plates 305c, the rotation of the actuating plates 305b will drive the rotation of the closing plates 305c, thereby exposing the lower opening of the first receiving cylinder 203a, so that the solid raw material falls down.

[0052] Then the rotating ring 204a continues to rotate, so that the protruding ring 204b corresponds with the first receiving cylinder 203a and the second receiving cylinder 203b. At this time, the first receiving cylinder 203a and the second receiving cylinder 203b are in a position far apart from each other. The first receiving cylinder 203a is used to continue to receive the raw material above, while the second receiving cylinder 203b transports the raw material downward, thus completing one raw material transfer process.

[0053] The copper-containing solid waste is transported in a quantitative and stable manner to the next processing stage through the segmented transmission of the transmission steel belt 502 and the first receiving cylinder 203a and the second receiving cylinder 203b. Furthermore, the residual heat during the transmission process is used to allow the raw materials to continue to react, ensuring the completeness of the reaction.

[0054] Meanwhile, the speed of raw material transmission can be controlled by the operator, and the gas discharge cylinder 203c cools the first receiving cylinder 203a, discharges excess gas inside, or introduces reaction gas into the first receiving cylinder 203a, thereby changing or controlling the reaction process of the raw materials, thereby increasing the degree of completion of the raw material reaction and increasing the yield of subsequent copper ingots.

[0055] Example 2 Reference Figure 9The second embodiment of the present invention provides a method for integrated treatment of copper-containing solid waste through continuous pyrolysis, gasification, and smelting, comprising: Before transmission, the copper-containing composite solid waste is pre-treated by mechanical crushing (jaw crusher, pulverizer) to reduce the particle size to 1-5mm, and then magnetic separation, electrostatic separation or gravity separation is used to separate metallic copper from non-metallic components.

[0056] S1: The raw material in the feeding cylinder 403b is first transferred to the storage bin 403a through the valve, and then the raw material is transferred and put into the pyrolysis chamber 101 through the valve at the lower end of the storage bin 403a.

[0057] In this process, an inert atmosphere is filled into the pyrolysis chamber 101 and the pyrolysis chamber 101 is preheated to pyrolyze the composite solid waste and separate the pyrolysis solid products. The pyrolysis chamber 101 is preheated and maintained between 450℃ and 700℃. At this temperature, the polymer's high molecular chains break on a large scale, generating olefins, alkanes and oxygen-containing compounds. Copper catalyzes and promotes the breaking of carbon-carbon bonds. When the temperature is between 600℃ and 700℃, the residual organic matter carbonizes, copper reacts with carbon to generate low-valence copper or alloys, and some inorganic matter melts to form slag.

[0058] Preferably, the pyrolysis atmosphere is a mixture of nitrogen and argon. After pyrolysis of copper-containing organic composite solid waste and waste plastics, pyrolysis solid products and pyrolysis gas are obtained. The pyrolysis solid products enter the gasification chamber 102 with the transmission steel belt 502, and the pyrolysis gas is used to power the copper-containing organic composite solid waste treatment system.

[0059] Among them, copper-containing composite solid waste mainly includes copper-containing electronic waste (such as circuit boards, wires and cables) and copper-containing resin composite materials. It is characterized by the close combination of copper with organic polymers (such as epoxy resin and polyvinyl chloride) and may contain impurities such as glass fiber and inorganic fillers.

[0060] S2: Then the infrared sensing module 402 detects the raw materials in the pyrolysis chamber 101, the motor starts, drives the gear 307 to rotate, and then controls the rack 306 to slide, further opening the door 401.

[0061] Then, the control will be adjusted according to the different pyrolysis conditions. When there are incompletely pyrolyzed particles, they are transported to the gasification chamber 102 by the transmission steel belt 502 for gasification. For copper-containing solid waste that has been fully pyrolyzed and does not need to be gasified, it will be directly entered into the subsequent process without gasification after adjustment.

[0062] When there are incompletely pyrolyzed particulate matter, the pyrolysis solid products are transported to the gasification chamber 102 by the transmission steel belt 502. First, the gasification chamber 102 is filled with a gasification atmosphere, and the gasification chamber 102 is preheated and maintained at a certain temperature. The pyrolysis solid products enter the gasification chamber 102 with the transmission steel belt 502. The pyrolysis solid products are gasified in the gasification atmosphere to obtain gasified gas and gasified solid products. The gasified solid products enter the melting chamber 103 with the transmission steel belt 502. The gasified gas is used to supply energy for the copper-containing organic composite solid waste treatment system.

[0063] The temperature of the vaporization chamber 102 is 700℃-1000℃, the vaporization atmosphere is a mixture of water vapor and nitrogen, and the steel belt speed is 0.1m-1m / min.

[0064] S3: Then the gasification chamber 102 door 401 opens, the stepper motor 204e turns on simultaneously, and pushes the first receiving cylinder 203a upward, so that the upper end face of the first receiving cylinder 203a is flush with the protruding part of the bent part, and the raw material falls naturally into the first receiving cylinder 203a on the bent part.

[0065] The gasified solid product is transported to the melting chamber 103 by the transmission steel belt 502 using the rotating component 204. The gasified solid product is melted in the melting atmosphere to obtain molten copper and molten tail gas. The molten copper enters the cooling chamber 104 through the solenoid valve, and the molten tail gas is discharged after being purified.

[0066] During the smelting of gasified solid products, the temperature of smelting chamber 103 is 1000℃-2000℃, and the smelting atmosphere is nitrogen, argon, or a mixture of both; the smelting tail gas is purified by electrostatic dust removal or bag filter dust removal.

[0067] S4: Then, using the valves installed in the melting chamber 103 and the cooling chamber 104, the molten raw material is transported to the cooling chamber 104, where the molten copper is cooled to obtain copper ingots.
