Description

[0001] The invention relates to the technical field of waste copper purification, in particular to a waste copper purification and recovery device. Background Art

[0002] With the rapid development of science and technology, electronic equipment used in various fields all use copper materials. When these devices are eliminated, the copper inside them becomes scrap copper. In order to improve the sustainable utilization rate of this copper, purification and recycling equipment is needed to effectively process this scrap copper.

[0003] Currently, the most commonly used method for recycling and purifying scrap copper is smelting, and this purification method is the most efficient. However, there are certain defects in purifying metallic copper by smelting. Since scrap copper needs to be continuously fed into the furnace, and the furnace cavity is limited, the amount of scrap copper fed each time is limited. At the same time, this intermittent smelting cannot completely remove the slurry remaining on the inner wall of the furnace. That is, the scrap copper smelting causes loss due to the furnace, which not only affects the subsequent smelting, but is also not conducive to the effective utilization rate of metallic copper.

[0054] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0055] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0056] A waste copper purification and recovery device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0057] Example 1:

[0058] Combine Figures 1-10As shown, the present invention provides a waste copper purification and recovery device, including a melting mechanism 100, an overflow discharge mechanism 200 arranged in the melting mechanism 100, a scraping mechanism 300 arranged on the melting mechanism 100, a slag removal mechanism 400 arranged on the scraping mechanism 300, and a linkage assembly 500 arranged on the slag removal mechanism 400. The melting mechanism 100 is used to provide a container for continuous smelting of waste copper, the overflow discharge mechanism 200 is used to extrude and empty the molten copper liquid and residual slurry, the scraping mechanism 300 is used to provide a platform for quickly scraping off the residual slurry, the slag removal mechanism 400 is used to filter the waste slag in the copper liquid, and the linkage assembly 500 is used to provide kinetic energy for the transportation of the waste slag.

[0059] The melting mechanism 100 includes a pressure-bearing base 110 and a partition 150, an outer furnace 120 mounted on the base 110, and an inner furnace 140 mounted on the base 110. The inner wall of the outer furnace 120 is provided with a flame vent 130, and the partition 150 is used to provide a top seal for the gap between the outer furnace 120 and the inner furnace 140 to increase the heating speed of the inner furnace 140.

[0060] A plurality of evenly distributed feet 160 are installed at the bottom of the base 110;

[0061] A symmetrically distributed first slide rail 170 and a second slide rail 180 are provided between the base 110 and the outer furnace 120 , and a load-bearing member 190 is installed in the base 110 ;

[0062] The load-bearing member 190 is composed of a horizontal plate and a chassis, and a hole is opened at the inner end of the horizontal plate;

[0063] The overflow discharge mechanism 200 includes a base plate 230 disposed at the bottom of the inner cavity of the inner furnace 140, a first slide bar 210 movably mounted in the first slide rail 170, a second slide bar 220 movably mounted in the second slide rail 180, a bearing 260 mounted in a hole at the inner end of the horizontal plate, and a gear shaft 250 mounted in the bearing 260;

[0064] Adapters are installed on the tops of the first slide bar 210 and the second slide bar 220 and the bottom of the chassis 230 . There are two sets of adapters, and the two support arms 240 are installed on the two sets of adapters respectively.

[0065] A motor 270 is provided in the chassis, and a driving gear is installed at the bottom end of the transmission shaft in the motor 270 , and a chain 280 is connected to the driving gear and the gear shaft 250 .

[0066] Currently, the main channels for recycling scrap copper include retailers, traders, and scrap metal recycling stations. These scrap coppers are mixed with impurities such as plastic, rubber, and slag. These scrap coppers need to go through processes such as decontamination, disassembly, classification, and fragmentation before smelting and purification. However, this smelting and purification requires the fragmented scrap copper to be put into the furnace. The existing furnace needs to intermittently stop supplying heat after a certain amount of scrap copper is put into it for smelting. The smelting operation of the next batch of scrap copper can only be carried out after the smelted copper liquid is completely transferred. However, this intermittent smelting will increase energy loss, and a large amount of slurry is likely to accumulate on the inner wall of the furnace, which will affect the overall utilization rate of the scrap copper purification.

[0067] The device is provided with an inner furnace 140 and a chassis 230 in a spliced manner, and an outer furnace 120 and a partition 150 are arranged outside the inner furnace 140. When heat energy continuously flows from the flame mouth 130 and into the gap formed by the outer furnace 120, the inner furnace 140 and the partition 150, the built-in inner furnace 140 can continuously melt the scrap copper put into it. As the scrap copper is continuously delivered to the strong light in the inner furnace 140, when the copper liquid continues to increase, the upwelling copper liquid can flow out from the inclined tube at the top of the inner furnace 140. At this time, the furnace body structure in this spliced manner can completely melt and purify the processed scrap copper without stopping operation, thereby improving the efficiency of scrap copper refining and purification, and reducing the loss of scrap copper caused by the furnace during the smelting process.

[0068] Example 2:

[0069] Combine Figures 6-10 As shown, based on Example 1, the scraper mechanism 300 includes a beam rail 310 fixedly installed on the top of the base 110, a clamp 320 installed on the beam rail 310, and a material guide trough 330 movably installed in the clamp 320. The beam rail 310 is a U-shaped structure as a whole, and sliding grooves are provided in the two end rods of the beam rail 310.

[0070] Preferably, a rectangular limiting ring is provided at the outer end of the guide trough 330. In this case, the rectangular limiting ring is used to provide calibration protection for the lateral movement of the guide trough 330. When the inclined end of the inner end of the guide trough 330 moves to directly below the filter residue discharge assembly 450, the notch on its inner side can provide an effective transfer path for the fallen waste residue, thereby improving the self-cleaning efficiency of the waste residue during the scrap copper smelting process.

[0071] The pressure plate 370 is movably mounted in the chute, and a scraper 380 is mounted on the bottom of the inner side of the pressure plate 370;

[0072] A sealing plate 350 is installed on the beam rail 310 , and a second hydraulic component 360 is fixedly installed in the middle of the sealing plate 350 .

[0073] Preferably, the two ends of the sealing plate 350 are fixedly mounted on the two ends of the beam rail 310 by two combination bolts. At this time, the beam rail 310 and the sealing plate 350 forming a closed structure can provide protection for the deformation of the pressure plate 370 and the scraper 380 until the chassis 230 moves to the top of the inner furnace 140 and until the top surface of the chassis 230 is level with the bottom blade of the scraper 380. As the scraper 380 scrapes the top surface of the chassis 230, the metal slurry remaining on the top surface of the chassis 230 can be completely cleared before it solidifies.

[0074] The outer end of the hydraulic sub-rod in the second hydraulic component 360 is installed in the column head in the middle of the outer side of the pressure plate 370;

[0075] Two column heads 340 are installed on the side of the outer end of the guide trough 330.

[0076] Preferably, the inner wall of the guide trough 330 is provided with a silicon dioxide protective layer to improve the resistance to high temperature molten copper.

[0077] Example 3:

[0078] Combine Figure 3 、 Figure 4 and Figure 8 As shown, based on Example 1, the slag removal mechanism 400 includes a suspension 410 arranged on the top of the beam rail 310, a column 420 installed on the suspension 410, a first hydraulic component 430 is installed in the clamping plate of the column 420, a support plate 440 is installed at the bottom end of the hydraulic sub-rod in the first hydraulic component 430, and a filter residue discharge assembly 450 is provided in the support plate 440.

[0079] Preferably, the base 451 in the initial state is in a suspended state and is located directly above the inner furnace 140. At this time, the gap formed between the base 451 and the inner furnace 140 is used to facilitate the rapid delivery of scrap copper. When the first hydraulic component 430 is running, its internal hydraulic sub-rod will push the support plate 440 and the slag discharge assembly 450 into the copper water in the inner cavity of the inner furnace 140 at a steady pressure. At this time, the squeezing of the copper water by the base 451 will cause the waste slag to overflow to the edge, and finally be collected and cleaned by the slag discharge assembly 450.

[0080] Two T-shaped ends are provided on the end of the support plate 440 away from the first hydraulic component 430;

[0081] The filter residue discharge assembly 450 is used to collect waste residue. After the filter residue discharge assembly 450 collects the waste residue and resets, the guide chute 330 can be moved to the bottom of the filter residue discharge assembly 450 and provide a transfer platform for the waste residue.

[0082] The filter residue discharge assembly 450 includes a base 451 , a hopper 452 is installed at the bottom of the base 451 , and evenly distributed filter slots 453 are opened on the top of the side of the hopper 452 .

[0083] Preferably, a cylindrical cavity is provided in the end of the bottom of the base 451, and evenly distributed material guide slots are provided on the inner wall of the column head. When the base 451 collects the waste residue, the waste residue will eventually be discharged from the material guide slots.

[0084] A blocking guide rod 454 is movably installed inside the base 451 , and a gasket 455 is provided on the blocking guide rod 454 , and the gasket 455 is located in the gap between the base 451 and the hopper 452 ;

[0085] A clamp 456 is installed on the top of the blocking guide rod 454 , a spring 457 is provided between the base 451 and the clamp 456 , and the spring 457 is located outside the rod body of the blocking guide rod 454 .

[0086] Preferably, as the waste slag in the copper liquid floats and accumulates, the first hydraulic component 430 is in operation, and its internal hydraulic sub-rod will control the filter residue discharge assembly 450 to be pressed into the inner cavity of the inner furnace 140 as a whole until the waste slag is filtered and collected by the filter residue discharge assembly 450. After the collected waste slag is discharged from the guide groove in the base 451, as the top of the blocking guide rod 454 is pressed down by the suspension 410, a gap will be formed between the hopper 452 and the blocking guide rod 454, and eventually the waste slag will fall down from the gap. At this time, the fallen waste slag can be collected and transferred by the guide trough 330.

[0087] Example 4:

[0088] Combine Figures 1-4 As shown, in the above embodiment, the linkage assembly 500 includes two propulsion oblique arms 510 movably mounted in the two end plates of the suspension 410, a pad 550 fixedly mounted on the suspension 410, and a vertical rod 540 mounted on the pad 550, and a pressure plate 520 movably mounted on the top of the two propulsion oblique arms 510.

[0089] Preferably, the rod bodies in the two propulsion oblique arms 510 are installed in the suspension 410 through bearings. When the support plate 440 drives the filter residue discharge assembly 450 to descend as a whole, the two propulsion oblique arms 510 can be tilted downward in a circular shape with the bearings, and the vertical rod 540 will be pressed and descend. At this time, the pressure plate 520 will push the two reset oblique arms 530 to extend outward, and finally the two column heads 340 movably installed at the bottom ends of the two reset oblique arms 530 will drive the material guide trough 330 to move outward stably. At this time, the moving material guide trough 330 can be linked with the lifting and lowering of the filter residue discharge assembly 450 to achieve linkage operation.

[0090] The other end of the pressing plate 520 is movably mounted with two reset oblique arms 530 , and the bottom ends of the two reset oblique arms 530 are movably mounted on the two column heads 340 ;

[0091] Two propulsion inclined arms 510 are movably mounted on two T-shaped column heads;

[0092] The top end of the vertical rod 540 is adapted to penetrate into the vertical hole inside the pressing plate 520;

[0093] A compression spring 560 is provided on the outside of the vertical rod 540 , and the bottom end of the compression spring 560 is pressed on the cushion 550 , while the top end of the compression spring 560 is pressed on the bottom of the pressure plate 520 .

[0094] Preferably, the vertical rod 540 is used to provide calibration protection for the lifting and lowering of the pressure plate 520. When the above-mentioned two reset inclined arms 530 are in a compressed state, as the support plate 440 is reset, the compression spring 560 in a compressed state will provide an elastic thrust for the pressure plate 520 to quickly reset.

[0095] Example 5:

[0096] Combine Figure 6 and Figure 8 As shown, in the above embodiment, the flame nozzle 130 can serve as a path for the flame to be sprayed, wherein the gap between the outer furnace 120 and the inner furnace 140 can provide a loading platform for the heating coil.

[0097] Preferably, an arc-shaped notch is provided at the top of the inner furnace 140 , and the arc-shaped notch is adapted to fit the pressure plate 370 and the scraper 380 to facilitate scraping off the residual copper slurry.

[0098] The working principle and use process of the present invention are as follows: after the sorted scrap copper is classified, the sheared scrap copper material needs to be put into the furnace. As the scrap copper is melted at high temperature, the copper and other impurities will be separated, and the waste residue will float to the upper layer of the copper liquid. Therefore, workers need to control mechanical equipment to clean the waste residue in the furnace;

[0099] After the sorted scrap copper is smelted using the device, as the waste slag accumulates and floats in the furnace, the first hydraulic component 430 can be operated until the hydraulic sub-rod inside it extends downward, and the support plate 440 fixed at the bottom end of the hydraulic sub-rod will drive the base 451 and the hopper 452 to descend downward until the bottom of the hopper 452 extends into the copper liquid in the form of a funnel-shaped slope. At this time, the floating waste slag will enter the groove at the top of the hopper 452 from the multiple filter slots 453 under the guidance of the slope and the extrusion of the copper liquid. At this time, the waste slag can be quickly filtered out, and as the hydraulic sub-rod in the support plate 440 is reset, the filter residue discharge assembly 450 can separate the filtered waste slag from the copper liquid until the top end of the blocking guide rod 454 is attached to the circular gasket at the top end of the suspension 410. As the blocking guide rod 454 is continuously pressurized, its bottom end will fall downward from the hole in the middle of the hopper 452.

[0100] At the same time, the lifting movement of the above-mentioned support plate 440 will apply pressure to the two propulsion inclined arms 510. At this time, the two propulsion inclined arms 510 will apply outward thrust to the pressure plate 520 and the two reset inclined arms 530, and the two reset inclined arms 530 will push the column head 340 and the column head 340 to move back and forth along the top of the outer furnace 120. When the guide chute 330 moves outward, the filter residue discharge component 450 is in a downward trend at this moment. When the guide chute 330 is reset inward, the filter residue discharge component 450 will carry the waste residue upward, and finally the exposed pores in the middle of the hopper 452 can quickly discharge the waste residue into the inner side of the guide chute 330, thereby facilitating the rapid emptying and cleaning of the waste residue.

[0101] The furnace-like structure formed by the inner furnace 140 and the bottom plate 230 can serve as a carrier for the scrap copper melt. As the flame is injected from the flame nozzle 130 into the gap between the outer furnace 120 and the inner furnace 140, the scrap copper can be effectively smelted. After the above-mentioned waste slag is cleaned, scrap copper can be continuously added to form molten copper and discharged outward from the inclined pipe at the top of the inner furnace 140 until the sorted scrap copper can be completely refined.

[0102] When the scrap copper is smelted, the motor 270 can be started. At this time, the gear at the bottom end of the transmission shaft in the motor 270 drives the chain 280, and the chain 280 drives the gear shaft 250. At this time, the first slide bar 210 and the second slide bar 220 constrained by the first slide rail 170 and the second slide rail 180 can extend at the same speed and in opposite directions. Finally, the extension of the first slide bar 210 and the second slide bar 220 will prompt the two supporting force arms 240 to lift the chassis 230 upward along the inner cavity of the inner furnace 140 until the copper liquid remaining in the inner cavity of the inner furnace 140 is completely emptied.

[0103] As the chassis 230 is lifted to the top of the inner furnace 140 and is level with its port, the second hydraulic component 360 can be operated until the hydraulic sub-rod in the second hydraulic component 360 pushes the pressure plate 370 and the scraper 380 to scrape toward the top of the chassis 230. The pressure plate 370 is limited by the two slide grooves in the beam rail 310. The scraper 380, which is compressed and forms a semicircular structure, can effectively squeeze the slurry remaining on the top of the chassis 230 into the inclined tube at the top of the inner furnace 140, thereby improving the complete utilization of the scrap copper smelt.

[0104] Although the 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
