[0002] Waste residue copper recovery is to purify metal waste containing copper substances by using a recovery process and process the metal waste into usable copper metal or copper alloy. The existing recovery process includes vibration screening, airflow screening, gravity separation, eddy current separation, and flotation method, etc.

[0003] When the flotation method is used to recover the copper-containing mineral powder, a reaction reagent such as a collector is usually introduced into the copper-containing mineral powder, so that the copper particles are hydrophobic, and thus the copper particles can be adsorbed by the bubbles and floated to the surface of the slurry, while the hydrophilic impurities remain at the bottom.

[0004] However, after the mineral powder is introduced into the collector, the hydrophobicity of the surface of the copper particles is significantly enhanced, and the copper particles may be aggregated due to the hydrophobic force to form a metal group, and other metal particles may also be included in the metal group. In the reaction process, the reaction time needs to be prolonged to ensure that all the copper particles in the metal group can float up, but this way will cause the problems of long reaction time and low recovery efficiency.

[0043] First embodiment

[0044] Please refer to Figures 1-6 As shown in the figure, it is a smelting waste slag copper resource cascade recovery device in the first embodiment of the application, including a tank body 100 with an opening at the top edge, a scraper assembly 200, a stamping assembly, and a storage shell 400 for sleeving on the tank body 100. It should be noted that please refer to Figure 1 The top edge of the tank body 100 is an open tank body 100.

[0045] Specifically, the tank body 100 is used to contain the recovered metal and the reaction reagent, and the reaction reagent is used to react with the recovered metal to form copper particles floating on the surface of the reaction reagent. It should be noted that the recovered metal is a metal waste doped with copper particles, which contains different types of metal particles. In this embodiment, the reaction reagent is introduced into the tank body 100, so that the reaction reagent can react with the recovered metal, and the copper particles in the recovered metal can float to the surface of the reaction reagent. It should be noted that the flotation method in the prior art is used, and the reaction reagent can use the collector of the conventional technology in the prior art.

[0046] The scraper assembly 200 includes a plurality of first scrapers 210 rotatably connected to the top edge of the tank body 100. The first scraper 210 is used to scrape the copper particles floating on the surface of the reaction reagent towards the direction of the storage shell 400, so as to separate the copper particles from the recovered metal and scrape them into the storage shell 400 for collection.

[0047] The stamping assembly comprises a plurality of stamping nozzles 300, which are arranged at the bottom of the tank body 100 in a circumferential direction and have an output direction towards the top edge of the tank body 100, so that the plurality of stamping nozzles 300 form a plurality of interlaced stamping gases in the tank body 100 to disperse the recovered metal into metal particles by the plurality of stamping gases.

[0048] In the specific operation process, first, the recovered metal and the reaction reagent are introduced into the tank body 100 to react, so as to separate the copper particles in the recovered metal and make them float to the surface of the reaction reagent. Since the recovered metal and the reaction reagent are reacted, the hydrophobicity of the copper particles is significantly enhanced, and the copper particles may be aggregated due to the hydrophobic force to form a metal group, and other metal particles may also be included in the metal group. If the reaction time is long, the stamping assembly and the scraper assembly 200 of the present application are used, so that the stamping gas can be input by the plurality of stamping nozzles 300 after the stamping assembly is started, and the output direction of the plurality of stamping nozzles 300 is towards the top edge of the tank body 100, so that the plurality of stamping nozzles 300 form a plurality of interlaced stamping gases in the tank body 100. The interlaced stamping gases can disperse the recovered metal into metal particles, so that the copper particles can quickly react with the reaction reagent and float to the surface of the reaction reagent. Finally, the copper particles floating on the surface of the reaction reagent can be scraped towards the receiving housing 400 by the scraper assembly 200, so as to separate the copper particles from the recovered metal and scrape them into the receiving housing 400 for collection. Through the above arrangement, the problems of long reaction time and low recovery efficiency in the prior art can be solved.

[0049] In some preferred embodiments, in order to facilitate the recycling of copper particles, please refer again to Figure 1 As shown in the figure, the receiving housing 400 can be inclinedly sleeved at the top of the tank body 100, and has a discharge passage at the bottom end of the inclination, so that the operator can quickly collect the copper particles.

[0050] In addition, in some actual cases, since there is some deposited recovered metal in the tank body 100, in order to realize the recycling of all copper particles in the recovered metal, in the present example, the recycling device further comprises a first-stage spiral separation passage 500 having at least two first discharge ports 510, which is used to communicate with the tank body 100, so that the recovered metal deposited at the bottom of the tank body 100 is transmitted along the spiral path of the spiral separation passage to separate the copper particles from the copper-containing mixed particles in the recovered metal. Among them, at least one first discharge port 510 is used to transmit the copper particles, and at least one other first discharge port 510 is used to transmit the copper-containing mixed particles.

[0051] For details, please refer to Figure 2As shown, a pipeline with a valve can be arranged at the bottom of the tank body 100. By opening the valve, the recovered metal deposited at the bottom of the tank body 100 can be transported to the primary spiral separation channel 500 for primary spiral transmission. Since the density of copper particles is high, that is, the density of copper particles is greater than that of other metal particles in the recovered metal, at this time, the density difference is used to make the copper particles in the recovered metal spiral along the inside of the primary spiral separation channel 500, while the copper-containing mixed particles spiral along the outside of the primary spiral separation channel 500, thereby separating a part of the copper particles in the recovered metal, and after the separation is completed, the copper particles can be transported through a first discharge port 510, while the copper-containing mixed particles are transported through another first discharge port 510.

[0052] In some preferred embodiments, the recycling device further comprises a material transmission assembly 600 and a secondary spiral separation channel 700 with at least two second discharge ports 710;

[0053] The secondary spiral separation channel 700 is arranged in cross overlap with the primary spiral separation channel 500, and the material transmission assembly 600 is used to transmit the copper-containing mixed particles from the bottom to the top of the secondary spiral separation channel 700, so that the secondary spiral separation channel 700 separates the copper particles and non-copper particles in the copper-containing mixed particles and transports them through the at least two second discharge ports 710, respectively.

[0054] Specifically, the copper-containing mixed particles transported by the first discharge port 510 are transmitted from the bottom to the top by the material transmission assembly 600, and the copper-containing mixed particles are subjected to secondary separation by the secondary spiral separation channel 700. The density difference between the copper particles and the non-copper particles is used to make the copper particles spiral along the inside of the secondary spiral separation channel 700, while the non-copper particles spiral along the outside of the secondary spiral separation channel 700. The secondary spiral separation channel 700 can completely separate the copper particles and non-copper particles in the copper-containing mixed particles, and finally the copper particles and non-copper particles are respectively transported through the two second discharge ports 710.

[0055] In some preferred embodiments, in order to facilitate the collection of copper particles and non-copper particles, the recovery device further comprises a first discharging component 520 and a second discharging component 720, wherein the first discharging component 520 is used to guide and transport the copper particles separated by the first spiral separation channel 500, and the second discharging component 720 is used to guide and transport the copper particles and non-copper particles separated by the second spiral separation channel 700, respectively. It should be noted that the first discharging component 520 and the second discharging component 720 can be a recovery shell that can be inclined, and has a discharging channel at the bottom end of the inclination, so that the operator can quickly collect the copper particles and non-copper particles.

[0056] It should be noted that in the present embodiment, the material conveying assembly 600 comprises a material conveying channel 610, a spiral conveying rod 620 and a first driver 630. One end of the material conveying channel 610 is in communication with a first discharging port 510, and the other end is opposite to the top of the second spiral separation channel 700. The spiral conveying rod 620 is arranged in the material conveying channel 610 and is driven to rotate by the first driver 630, so that the spiral conveying rod 620 conveys the non-copper particles to the top of the second spiral separation channel 700.

[0057] Specifically, the first driver 630 can be a servo motor in the prior art.

[0058] In order to facilitate the scraping of the copper particles floating on the surface of the reaction reagent, in the present example, the scraper assembly 200 further comprises a second driver 220 and a driving shaft 230 connected to the output end of the second driver 220.

[0059] The second driver 220 is used to drive the driving shaft 230 to rotate, and a plurality of first scrapers 210 are circumferentially spaced apart on the driving shaft 230. Specifically, the second driver 220 can be a servo motor in the prior art.

[0060] In addition, since the recovered metal may be attached to the inner wall of the tank 100, in the present embodiment, the scraper assembly 200 further comprises a plurality of transmission arms 240 and a plurality of second scrapers 250.

[0061] Each second scraper 250 is circumferentially spaced apart from the driving shaft 230 by each transmission arm 240, so that each transmission arm 240 and each second scraper 250 are synchronously driven by the driving shaft 230 to scrape the inner wall of the scraper.

[0062] Since the metal particles are attached to the inner wall of the tank 100 with uncertainty, the transmission arm 240 further comprises a connecting part 241 connected with the driving shaft 230 and a swing part 242 slidably connected with the inner wall of the tank 100, and the second scraper 250 is arranged on the swing part 242;

[0063] Wherein, the inner wall of the tank 100 is provided with a spiral chute 110 for the swing part 242 to slide, so that when the driving shaft 230 rotates, the swing part 242 swings along the spiral path of the spiral chute 110, so that the second scraper 250 scrapes the recovered metal attached to the inner wall of the tank 100. Specifically, at least two second scrapers 250 are arranged on each swing part 242.

[0064] That is, when the second driver 220 drives the driving shaft 230 to rotate, the swing part 242 will swing along the spiral path of the spiral chute 110, so as to increase the scraping area of the second scraper 250 on the tank 100, and at the same time, the up and down swinging of the swing part 242 and the second scraper 250 can also scatter the clumped recovered metal, further improving the recovery efficiency of copper particles and improving the practicability of the device.

[0065] In some optional embodiments, the recovery device can further comprise a bracket with a sliding wheel, and the tank 100, the scraper assembly 200, the stamping assembly, the storage shell 400, the primary spiral separation channel 500, the material conveying assembly 600 and the secondary spiral separation channel 700 are arranged on the bracket.

[0066] In some other optional embodiments, a pipe for introducing a reaction reagent can be arranged on the top of the primary spiral separation channel 500 and the secondary spiral separation channel 700, so that there is sufficient reaction reagent on the primary spiral separation channel 500 and the secondary spiral separation channel 700.

[0067] In summary, the smelting slag copper resource cascade recovery device shown in the embodiment has at least the following beneficial effects compared with the flotation method in the prior art:

[0068] In the smelting waste residue copper resource gradient recovery device shown in the application, the tank body 100, the scraper assembly 200, the punching assembly and the storage shell 400 are arranged, so that after the recovered metal and the reaction reagent are introduced into the tank body 100 for reaction, the copper particles in the recovered metal are separated and float to the surface of the reaction reagent. Because the recovered metal and the reaction reagent are in contact, the hydrophobicity of the surface of the copper particles is significantly enhanced, the copper particles may be gathered together due to the hydrophobic force, and the metal group may also include other metal particles. The reaction time is relatively long. The punching assembly and the scraper assembly 200 are arranged, so that after the punching assembly is started, the punching gas can be input by the plurality of punching nozzles 300, and the output directions of the plurality of punching nozzles 300 are all directed to the top edge of the tank body 100, so that the plurality of punching nozzles 300 form a plurality of interlaced punching gases in the tank body 100. The interlaced punching gases can disperse the agglomerated recovered metal into metal particles, so that the copper particles can rapidly react with the reaction reagent and float to the surface of the reaction reagent. Finally, the copper particles floating on the surface of the reaction reagent can be scraped by the scraper assembly 200 to the direction of the storage shell 400, so that the copper particles are separated from the recovered metal and scraped into the storage shell 400 for collection. Through the arrangement, the problems of long reaction time and low recovery efficiency in the prior art can be solved.

[0069] Second embodiment

[0070] The second embodiment of the application provides a control method of a smelting waste residue copper resource gradient recovery device. The control method is used for controlling the smelting waste residue copper resource gradient recovery device of the first embodiment. The control method comprises the following steps.

[0071] The recovered metal and the reaction reagent are introduced into the tank body 100 to react for a first preset time, so as to separate the copper particles in the recovered metal and make them float to the surface of the reaction reagent.

[0075] In the control method of the smelting slag copper resource gradient recovery device shown in the application, the tank body 100, the scraper assembly 200, the punching assembly and the storage shell 400 are included, so that after the recovered metal and the reaction reagent are introduced into the tank body 100 for reaction, the copper particles in the recovered metal will be separated and floated to the surface of the reaction reagent. Because the recovered metal and the reaction reagent, the hydrophobicity of the copper particles will be significantly enhanced, the copper particles may be aggregated due to the hydrophobic force to form a metal group, and the metal group may also include other metal particles. The reaction time is relatively long, so the punching assembly and the scraper assembly 200 of the application are used to enable the punching gas to be input by the plurality of punching nozzles 300 after the punching assembly is started, and the output directions of the plurality of punching nozzles 300 are all toward the top edge of the tank body 100, so that the plurality of punching nozzles 300 form a plurality of interlaced punching gases in the tank body 100.

Finally, the scraper assembly 200 can scrape the copper particles floating on the surface of the reaction reagent toward the direction of the storage shell 400, so as to separate the copper particles from the recovered metal and scrape them into the storage shell 400 for collection. Through the above setting, the problems of long reaction time and low recovery efficiency in the prior art can be solved.
