Description

Technical Field

[0001] This invention relates to the field of waste copper smelting technology, and in particular to an intensive smelting apparatus for waste copper pyrometallurgical recycling. Background Technology

[0002] Scrap copper smelting refers to the process of refining and processing recycled scrap copper into usable copper metal or copper alloys through high-temperature smelting and refining. It is an important component of the circular economy, reducing dependence on primary copper mines and lowering energy consumption and environmental pollution.

[0003] Currently, the existing smelting technology for scrap copper involves pouring a large amount of scrap copper into a smelting furnace, using the high temperature of the furnace to smelt the scrap copper into molten copper, and then manually pouring the molten copper into a molding die to form copper blocks. To improve recycling efficiency, valves are also installed at the bottom of the smelting furnace. After the scrap copper is smelted, the valves are opened so that the molten copper can be directly poured into the molding die to complete the shaping process.

[0004] However, during the smelting process of copper, a large number of solid impurities are generated, such as slag floating on the surface of the copper. In order to ensure the normal use of the copper block, the slag on the surface of the copper block must be removed before the copper block is shaped. The current method of removing slag is still to remove the slag from the copper block manually. This method will result in low slag removal efficiency, and the high temperature environment of the copper block during the removal process will also pose a risk of injury or death to the operators. Summary of the Invention

[0005] Based on this, the purpose of this invention is to provide an intensive smelting device for the pyrometallurgical regeneration of waste copper, so as to solve the technical problems of low efficiency and potential injury or death to operators in the existing slag removal methods in the background art.

[0006] The present invention provides an intensive smelting apparatus for pyrometallurgical recycling of waste copper, including a support frame, and a smelting furnace, a copper molten metal separation component, a copper molten metal shaping component, a scraping component, and a lifting drive for being mounted on the support frame.

[0007] The copper molten metal separation component and the copper molten metal shaping component are arranged sequentially below the smelting furnace, so that the copper molten metal smelted in the smelting furnace is separated by the copper molten metal separation component and then transferred to each cavity of the copper molten metal shaping component for shaping.

[0008] The scraping assembly includes a plurality of scrapers disposed opposite to each of the cavities, a transmission support rod for connecting the plurality of scrapers to each other, and a guide support rod disposed on the bracket, wherein a portion of the transmission support rod is slidably connected to the guide support rod;

[0009] The lifting driver is used to drive the copper molten metal shaping component, the scraper and the transmission support rod to move up and down synchronously. When the lifting driver drives the copper molten metal shaping component to descend, the transmission support rod slides along the guide path of the guide support rod, so that each scraper moves along the length direction of each cavity, so as to scrape and separate the scum in each cavity by means of multiple scrapers.

[0010] Furthermore, the smelting apparatus also includes a transmission pipeline and valves. The two ends of the transmission pipeline are respectively used to connect to the smelting furnace and the copper molten metal separation component, and are used to transmit the copper molten metal in the smelting furnace to the copper molten metal separation component for separation. The valves are used to stop / start the transmission of copper molten metal.

[0011] Furthermore, the copper-water separation assembly includes a separation box having multiple separation chambers;

[0012] The multiple separation chambers are interconnected, each separation chamber is disposed opposite to each cavity, and each separation chamber is provided with an opening for communicating with the cavity.

[0013] Furthermore, the smelting apparatus also includes a switching assembly, and the copper-water separation assembly includes a flexible lifting frame with multiple pistons;

[0014] The elastic lifting frame is elastically connected to the separating material box, and each piston is arranged opposite to each opening, passing through one side of the separating material box.

[0015] The switching assembly synchronously controls the opening and closing of the valve and the lifting and lowering movement of the elastic lifting frame.

[0016] Furthermore, the switching assembly includes a rod having at least one threaded portion, a pressure block pulsatingly connected to the threaded portion, a first transmission member connected to the switching element of the valve, and a second transmission member connected to the pressure block;

[0017] The rod is rotatably connected to the bracket. By rotating the rod, the pressure block moves toward the elastic lifting frame. The pressure block is used to press down the elastic lifting frame so that each piston seals each opening.

[0018] The pressure block is used to move the second transmission member toward the first transmission member, so that the second transmission member drives the first transmission member to rotate, thereby enabling the switch to control the valve to open.

[0019] Furthermore, the switch assembly also includes a rotating disk, and at least one end of the rod extends through one side of the bracket and is connected to the rotating disk.

[0020] Furthermore, the end dimension of each piston extends from one end near the opening to the other end, gradually increasing in size.

[0021] Furthermore, the copper molten metal shaping assembly includes a shaping template, and the shaping template has multiple cavities.

[0022] The shaping template is connected to the output end of the lifting driver.

[0023] Furthermore, the copper molten metal shaping assembly also includes a plurality of lifting devices disposed on the shaping template;

[0024] Each cavity is provided with at least one lifting device, and a support plate corresponding to multiple lifting devices is provided on the bracket. When the shaping template is lowered, the lifting device abuts against the support plate, so that the lifting device lifts the molten copper in the shaping template outward.

[0025] Furthermore, the lifting device includes an elastic element and a lifting rod. One end of the lifting rod is located outside the cavity, and the other end is attached to the bottom of the cavity. The two ends of the elastic element are respectively connected to the lifting rod and one side of the shaping template.

[0026] Compared with existing technologies, the advantages of using the intensive smelting apparatus for waste copper pyrometallurgical recycling shown in this invention are as follows:

[0027] The intensive smelting apparatus for pyrometallurgical recycling of waste copper disclosed in the application includes a smelting furnace, a copper molten metal separation component, a copper molten metal shaping component, a scraping component, and a lifting drive. In operation, the smelting furnace first smelts the waste copper to form molten copper. The copper molten metal separation component separates the molten copper into multiple streams. The various cavities of the copper molten metal shaping component collect these streams, allowing the molten copper to complete the shaping process within each cavity. However, during the smelting process, slag floating on the surface of the molten copper is generated. To facilitate the removal of slag, the scraping assembly and lifting drive are configured so that when the lifting drive drives the copper molten metal shaping assembly to descend, the transmission support rod slides along the guide path of the guide support rod. At this time, the transmission support rod moves, which drives each scraper to move along the length of each cavity. This allows multiple scrapers to scrape and separate the slag in each cavity, thus completing the slag separation process before copper molten metal shaping. This solves the technical problems of low efficiency and potential injury or death to operators in existing slag removal methods. Attached Figure Description

[0034] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0035] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Please see Figures 1-6As shown, a waste copper pyrometallurgical recycling intensive smelting device includes a support 100, and a smelting furnace 200, a copper molten metal separation component 300, a copper molten metal shaping component 400, a scraping component 500, and a lifting drive 600, which are installed on the support 100.

[0038] It should be noted that in this example, the smelting furnace 200 has the function of high-temperature smelting, which allows the scrap copper to be smelted and formed into molten copper after being put into the smelting furnace 200. In some optional embodiments, a cover plate can be arranged on the top of the smelting furnace 200, and a flue gas channel can be arranged on the cover plate. The cover plate can effectively prevent heat from spreading outward, and the flue gas channel can treat harmful flue gas. Since other structures constituting the smelting furnace 200 are conventional prior art in this field, they will not be described in detail here.

[0039] Specifically, in this example, the copper molten metal separation component 300 and the copper molten metal shaping component 400 are arranged sequentially below the smelting furnace 200, so that the copper molten metal smelted in the smelting furnace 200 is separated by the copper molten metal separation component 300 and then transferred to each cavity 410 of the copper molten metal shaping component 400 for shaping.

[0040] The scraping assembly 500 includes a plurality of scrapers 510 disposed opposite to each cavity 410, a transmission support rod 520 for connecting the plurality of scrapers 510 to each other, and a guide support rod 530 disposed on the bracket 100, a portion of the transmission support rod 520 being slidably connected to the guide support rod 530.

[0041] The lifting driver 600 is used to drive the copper molten metal shaping component 400, the scraper 510 and the transmission support rod 520 to move synchronously up and down. When the lifting driver 600 drives the copper molten metal shaping component 400 to descend, the transmission support rod 520 slides along the guide path of the guide support rod 530, so that each scraper 510 moves along the length direction of each cavity 410, so as to scrape and separate the scum in each cavity 410 through multiple scrapers 510.

[0042] In the specific operation process, the smelting furnace 200 is first used to smelt the scrap copper to form molten copper. The molten copper separation component 300 shown in this application can separate the molten copper and form multiple tributaries. The cavities 410 of the molten copper shaping component 400 can collect the multiple tributaries, so that the molten copper can complete the shaping process in each cavity 410. However, since slag will be generated on the surface of the molten copper during the smelting process, in order to facilitate the removal of slag, the scraping component 500 and the lifting drive 600 are set up so that the lifting drive... When the copper molten metal shaping assembly 400 is lowered, the transmission support rod 520 will slide along the guide path of the guide support rod 530. At this time, the transmission support rod 520 will move, and the transmission support rod 520 can drive each scraper 510 to move along the length direction of each cavity 410, so that the scum in each cavity 410 can be scraped and separated by multiple scrapers 510. This realizes the separation process of scum before copper molten metal shaping, and solves the technical problems of low efficiency and potential injury or death of operators in the existing scum removal methods.

[0043] It should be noted that in this application, the smelting apparatus also includes a transmission pipeline 700 and a valve 710. The two ends of the transmission pipeline 700 are respectively used to connect to the smelting furnace 200 and the copper-water separation component 300, and are used to transmit the copper-water in the smelting furnace 200 to the copper-water separation component 300 for separation. The valve 710 is used to stop / start the transmission of copper-water. It should be noted that in this example, both the valve 710 and the transmission pipeline 700 can be made of materials with high temperature resistance. Since the high temperature resistant transmission pipeline 700 and valve 710 are conventional prior art in this field, they will not be specifically described here.

[0044] In some preferred embodiments, to further improve operating efficiency, the copper-water separation assembly 300 includes a separation box 320 with multiple separation chambers 310 interconnected. Each separation chamber 310 is opposite to each cavity 410, and each separation chamber 310 has an opening 330 for connecting the separation chamber 310 to the cavity 410. The smelting apparatus also includes a switch assembly 800. The copper-water separation assembly 300 includes an elastic lifting frame 350 with multiple pistons 340. The elastic lifting frame 350 is elastically connected to the separation box 320. Each piston 340 is used to penetrate one side of the separation box 320 and is opposite to each opening 330. The switch assembly 800 synchronously controls the opening and closing of the valve 710 and the lifting movement of the elastic lifting frame 350.

[0045] Specifically, the switch assembly 800 includes a rod body 820 having at least one threaded portion 810, a pressure block 830 pulsatorically connected to the threaded portion 810, a first transmission member 840 connected to the switch member 711 of the valve 710, and a second transmission member 850 connected to the pressure block 830.

[0046] The rod 820 is rotatably connected to the bracket 100. By rotating the rod 820, the pressure block 830 moves toward the elastic lifting frame 350. The pressure block 830 is used to press down the elastic lifting frame 350 so that each piston 340 seals each opening 330.

[0047] The pressure block 830 is used to move the second transmission member 850 toward the first transmission member 840, so that the second transmission member 850 drives the first transmission member 840 to rotate, so that the switch member 711 controls the valve 710 to open.

[0048] In practical operation, rotating the rod 820 causes the threaded portion 810 on the rod 820 to drive the pressure block 830 to move. It should be noted that the pressure block 830 has an internal thread corresponding to the threaded portion 810, allowing the rod 820 and the pressure block 830 to form a screw-slider assembly. When the pressure block 830 moves forward, it presses down on the elastic lifting frame 350. Please refer to [link / reference needed]. Figure 6 As shown, inclined surfaces are arranged on the opposite surfaces of the pressure block 830 and the elastic lifting frame 350. When the pressure block 830 contacts the elastic lifting frame 350, the inclined surface of the pressure block 830 itself allows the pressure block 830 to move to the top of the elastic lifting frame 350. During the movement, the pressure block 830 will press down the elastic lifting frame 350, so that each piston 340 can seal the opening 330.

[0049] During the movement of the pressing block 830, the second transmission component 850 will also move. Utilizing the mutual transmission between the first transmission component 840 and the second transmission component 850, the first transmission component 840 will be driven to rotate during the transmission process between the second transmission component 850 and the first transmission component 840. The rotation of the first transmission component 840 will cause the switch component 711 to open the valve 710, thereby sealing the opening 330 while opening the valve 710. This ensures that the volume of molten copper in each separation chamber 310 of the separation box 320 is consistent, ensuring that the volume of molten copper flowing into the molding cavity 410 is the same, and guaranteeing that the volume of the finally shaped copper block is also the same.

[0050] It should be noted that the switch 711 can be a rod and a spherical structure with an opening. In other words, the second transmission member 850 is fixed to the rod, so that when the second transmission member 850 rotates, the spherical structure inside the valve 710 will rotate, so that the opening on the spherical structure is connected to the transmission pipeline 700, allowing copper liquid to be output, and vice versa.

[0051] In this example, the first transmission component 840 is a gear, and the second transmission component 850 is a rack.

[0052] When the rod 820 is rotated in the opposite direction, the pressure block 830 will move to the outside of the elastic lifting frame 350. The elasticity of the elastic lifting frame 350 will allow the piston 340 to contact the seal of the opening 330, and the valve 710 will also be in the closed state, so that the molten copper in the separation chamber 310 can flow into the mold cavity 410 for shaping.

[0053] In some preferred embodiments, to improve operating efficiency, the switch assembly 800 also includes a rotary disk 860, with at least one end of the rod 820 passing through one side of the bracket 100 and connected to the rotary disk 860, thereby facilitating operation by the staff.

[0054] In addition, the end size of each piston 340 can be extended from the end near the opening 330 from small to large towards the other end. That is, the end of the piston 340 is set at an acute angle to ensure the sealing performance of the opening 330.

[0055] In some other preferred embodiments, the copper molten metal shaping assembly 400 includes a shaping template 420, which has a plurality of cavities 410. The shaping template 420 is connected to the output end of the lifting driver 600, which can be a cylinder in the prior art.

[0056] To facilitate the removal of the copper block, the copper molten metal shaping assembly 400 also includes a plurality of lifting devices 430 disposed on the shaping template 420. Each cavity 410 is provided with at least one lifting device 430. A support plate 900 corresponding to the plurality of lifting devices 430 is provided on the bracket 100 so that when the shaping template 420 is lowered, the lifting device 430 abuts against the support plate 900, so that the lifting device 430 pushes the molten copper molten inside the shaping template 420 outward.

[0057] Specifically, the lifting device 430 includes an elastic element and a push rod. One end of the push rod is located outside the cavity 410, and the other end is attached to the bottom of the cavity 410. The two ends of the elastic element are respectively connected to the push rod and one side of the shaping template 420. That is, when the shaping template 420 descends to near the support plate 900, the support plate 900 can contact the end of the push rod, so that after the shaping template 420 continues to descend, the push rod will push out the cooled and shaped copper block, thereby further improving the demolding efficiency.

[0058] In summary, the intensive smelting apparatus for waste copper pyrometallurgical recycling shown in this embodiment has at least the following advantages compared with smelting apparatus in the prior art:

[0059] The intensive smelting apparatus for pyrometallurgical recycling of waste copper disclosed in the application includes a smelting furnace 200, a copper molten metal separation component 300, a copper molten metal shaping component 400, a scraping component 500, and a lifting drive 600. In specific operation, the smelting furnace 200 first smelts the waste copper to form molten copper. The copper molten metal separation component 300 separates the molten copper, forming multiple tributaries. The cavities 410 of the copper molten metal shaping component 400 collect these tributaries, allowing the molten copper to complete the shaping process within each cavity 410. However, during the smelting process, slag floating on the surface of the molten copper is generated. To facilitate… To remove slag, the scraping assembly 500 and the lifting drive 600 are configured such that when the lifting drive 600 drives the copper molten metal shaping assembly 400 to descend, the transmission support rod 520 slides along the guide path of the guide support rod 530. At this time, the transmission support rod 520 moves, which drives each scraper 510 to move along the length of each cavity 410. The multiple scrapers 510 scrape and separate the slag in each cavity 410, thereby completing the slag separation process before copper molten metal shaping. This solves the technical problems of low efficiency and potential injury or death to operators in the existing slag removal methods.
