Description

Technical Field

[0001] The invention relates to the technical field of metal recovery, and in particular to an energy-saving regeneration smelting system for copper-containing waste. Background Art

[0002] Recycling of scrap copper is pyrometallurgical recycling, which has a crude process and low recovery rate, resulting in waste of resources, energy consumption and environmental pollution. Scrap copper and copper-containing materials are pyrometallurgically smelted in a smelting furnace to produce crude copper ingots, which are then sold to copper processing companies. The crude copper is then refined into anode plates, which are then electrolytically refined into cathode copper. The cathode copper is melted again and processed into various copper product billets. The billets are further processed into raw materials for various electrical and electronic products.

[0003] At present, copper-containing waste is usually piled up in a smelting furnace for pyrometallurgy. The high temperature in the smelting furnace is used to smelt the copper-containing waste into molten copper. Finally, the smelting furnace is turned over to shape the molten copper through an external shaping mold for subsequent recycling, such as shaping into copper plates, copper rods and copper sheets.

[0004] However, due to the different sizes of copper-containing waste, when smelting batches of copper-containing waste, copper-containing waste of different sizes requires different amounts of heat. For example, when smelting copper-containing waste of larger size, it needs to be smelted for a long time, while copper-containing waste of smaller size can be smelted in a short time. However, when pouring molten copper, it is necessary to wait until the waste in the smelting furnace is completely molten copper before pouring. Therefore, when smelting copper-containing waste of different sizes, due to the different volumes of copper-containing waste, copper-containing waste of smaller size will be gasified during long-term smelting, which will lead to the waste of part of the copper-containing waste being wasted. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an energy-saving regeneration smelting system for copper-containing waste to solve the technical problem in the background technology that when smelting copper-containing waste of different sizes, due to the different volumes of the copper-containing waste, the smaller copper-containing waste will be gasified during long-term smelting, which will lead to the waste of part of the copper-containing waste.

[0010] Wherein, the filter screen is arranged at the discharge port of the cylinder, and the filter screen is used to filter the crushed copper-containing waste material, so as to output the copper-containing waste material meeting the preset size to the smelting device for smelting.

[0015] The first crushing roller is connected to the first transmission member, the second crushing roller is connected to the second transmission member, and the side of the first transmission member away from the first crushing roller is connected to the output end of the first driving member.

[0016] Furthermore, the flip assembly includes a first connecting member, a second connecting member, a first plate body and a second plate body;

[0017] The first connecting member and the second connecting member are connected to the first plate body and the second plate body respectively;

[0018] Wherein, the length dimension of the first connecting member is longer than the length dimension of the second connecting member.

[0019] Further, the cross section of the first plate body is arranged opposite to the bottom cross section of the cylinder body, and the cross section of the second plate body is arranged opposite to the middle cross section of the cylinder body.

[0020] Furthermore, the first plate body and the second plate body each have at least one bending area, so that when the first connecting member or the second connecting member moves, the first plate body or the second plate body respectively drives the copper-containing waste at the bottom of the cylinder or the copper-containing waste in the middle of the cylinder to move toward the top of the cylinder.

The material will not be gasified, which maximizes the utilization rate of the copper-containing waste. Since the copper-containing waste has a certain ductility, the copper-containing waste cannot be broken into fine copper-containing waste after one crushing, so that some of the larger copper-containing waste will accumulate on the top of the filter. In the present application, the turning component can be used to throw the copper-containing waste at the bottom and middle of the cylinder to the top of the cylinder, that is, the larger copper-containing waste can be crushed again, and the cycle is repeated until all the copper-containing wastes can pass through the holes of the filter, thereby ensuring the maximum utilization of the copper-containing waste and avoiding the gasification of some copper-containing waste.

[0037] See also Figure 1-Figure 6 As shown, the present invention provides an energy-saving regeneration smelting system for copper-containing waste, including a support 100, a crushing device 200 and a smelting device 300 arranged on the support 100.

[0038] Specifically, in order to solve the technical problem that when copper-containing wastes of different sizes are smelted, due to the different volumes of copper-containing wastes, the copper-containing wastes of smaller sizes will be gasified during long-term smelting, which will lead to the waste of part of the copper-containing wastes. In this embodiment, the crushing device 200 includes a cylinder 210 having an inlet port 211 and an outlet port 212, two crushing components 220 arranged in the cylinder 210, a turning component 230 and a filter screen 240, and the outlet port 212 is arranged opposite to the inlet port of the smelting device 300;

[0039] The two crushing assemblies 220 are symmetrically arranged in the cylinder 210 with respect to the center line of the cylinder 210, and there is an accommodating spacer 250 for accommodating the flip assembly 230 between the two crushing assemblies 220. The crushing assemblies 220 are used to crush the copper-containing waste;

[0040] The turning assembly 230 includes a rotating shaft 231 rotatably connected to the accommodating spacer 250, at least two connecting members connected to the rotating shaft 231, and at least two plates, each connecting member is connected to a plate, and the length of each connecting member is longer than the length of an adjacent connecting member, so that when the rotating shaft 231 rotates relative to the accommodating spacer 250, the at least two plates are turned over by the at least two connecting members to the copper-containing waste located at the bottom of the cylinder 210 and the copper-containing waste located in the middle of the cylinder 210;

[0041] The filter screen 240 is disposed at the discharge port 212 of the cylinder 210 , and is used to filter the crushed copper-containing waste materials, so as to output the copper-containing waste materials meeting a preset size to the smelting device 300 for smelting.

[0042] That is, copper-containing waste materials of different sizes are fed into the cylinder 210 through the feed port 211. It should be noted that the copper-containing waste materials may be copper wires, copper blocks, copper plates, cylinder blocks and other copper-containing waste materials of different sizes. The crushing assembly 220 in the cylinder 210 can crush the copper-containing waste materials of different sizes, so that the copper-containing waste materials of different sizes are crushed into fine copper-containing waste materials. Finally, the crushed copper-containing waste materials are filtered by the filter screen 240 located at the discharge port 212 of the cylinder 210, so that the copper-containing waste materials that finally enter the smelting device 300 have the same size, so as to realize the rapid smelting of the copper-containing waste materials in a short time. In addition, in the present application, the copper-containing waste materials of different sizes are first crushed and then smelted after screening, so as to realize the initial The copper-containing waste in the initial state and with a smaller size will not be gasified, thereby ensuring the utilization rate of the copper-containing waste to the greatest extent. In addition, due to the certain ductility of the copper-containing waste, the copper-containing waste cannot be broken into fine copper-containing waste after being crushed once, so that some of the larger copper-containing waste will accumulate on the top of the filter screen 240. In this embodiment, the turning component 230 can be used to throw the copper-containing waste at the bottom and middle of the cylinder 210 to the top of the cylinder 210, that is, the larger copper-containing waste can be crushed again, and this cycle is repeated until the size of all copper-containing waste can pass through the holes of the filter screen 240, thereby ensuring the maximum utilization of the copper-containing waste and avoiding the gasification of some copper-containing waste.

[0043] For a better understanding of this case, please refer to Figure 1-Figure 2As shown, the crushing device 200 is arranged on the smelting device 300, so that the copper-containing waste crushed by the crushing device 200 is facing the smelting device 300, so that the copper-containing waste is smelted by the smelting device 300. Specifically, in order to realize the crushing treatment of the copper-containing waste, in this embodiment, the crushing assembly 220 includes a first driving member 221, at least two crushing rollers, and at least two transmission members connected to each other, wherein each crushing roller is respectively connected to a transmission member, and at least one transmission member is connected to the output end of the first driving member 221.

[0044] It should be noted that the crushing components 220 in this embodiment are divided into two groups and are symmetrically distributed in the middle of the cylinder 210, and the accommodating spacer 250 formed between the two groups of crushing components 220 can be separated by two partitions. Specifically, one end of the two crushing rollers can pass through the side wall of the cylinder 210 and be rotatably connected to the side wall of the partition.

[0045] In some preferred embodiments, the first driving member 221 is arranged on the bracket 100 outside the cylinder 210 .

[0046] In some other preferred embodiments, the crushing assembly 220 includes a first crushing roller 222, a second crushing roller 223, a first transmission member 224 and a second transmission member 225, wherein the first crushing roller 222 is connected to the first transmission member 224, the second crushing roller 223 is connected to the second transmission member 225, and the first transmission member 224 is connected to the output end of the first driving member 221 on the side away from the first crushing roller 222.

[0047] The first transmission member 224 and the second transmission member 225 can both adopt mutually meshing gears, and the first driving member 221 can adopt a servo motor. Since the transmission between the gears and the servo motor belong to the conventional prior art in this field, no special explanation is given here, that is, the first driving member 221 is used to drive the first transmission member 224 to rotate, and through the mutual transmission between the first transmission member 224 and the second transmission member 225, the first crushing roller 222 and the second crushing roller 223 can be relatively rotated, so that the relative rotation between the first crushing roller 222 and the second crushing roller 223 can be used to crush copper-containing waste of different sizes.

[0048] In addition, in order to facilitate multiple crushing of the copper-containing waste in the middle and bottom of the cylinder 210, in this embodiment, the turnover assembly 230 includes a first connecting member 232, a second connecting member 233, a first plate 234 and a second plate 235, and the first connecting member 232 and the second connecting member 233 are connected to the first plate 234 and the second plate 235 respectively.

[0049] It should be noted that, in the embodiment, the first connecting member 232 and the second connecting member 233 do not limit the number of connecting members. Similarly, the first plate body 234 and the second plate body 235 do not limit the number of plate bodies. The connecting members and the plate bodies can be three, four, five, etc., and it should be noted that when the number of connecting members is three, the number of plate bodies is also three.

[0050] In this embodiment, a first connecting member 232, a second connecting member 233, a first plate 234 and a second plate 235 are used as examples, wherein the length dimension of the first connecting member 232 is longer than the length dimension of the second connecting member 233, the cross-section of the first plate 234 is arranged relative to the bottom cross-section of the cylinder 210, and the cross-section of the second plate 235 is arranged relative to the middle cross-section of the cylinder 210. Specifically, the first plate 234 and the second plate 235 each have at least one bending area, so that when the first connecting member 232 or the second connecting member 233 moves, the first plate 234 or the second plate 235 respectively drives the copper-containing waste at the bottom of the cylinder 210 or the copper-containing waste in the middle of the cylinder 210 to move toward the top of the cylinder 210.

[0051] That is, when the rotating shaft 231 is rotating, it will simultaneously drive the first connecting member 232 and the second connecting member 233 to move synchronously. By utilizing the size difference between the first connecting member 232 and the second connecting member 233, the first plate 234 can move to the bottom of the cylinder 210, and the second plate 235 can move to the middle of the cylinder 210. By utilizing the bending areas on the first plate 234 and the second plate 235, the copper-containing waste at the bottom or middle of the cylinder 210 can be moved to the top of the cylinder 210. Finally, due to the effect of gravity, the copper-containing waste can fall into the crushing assembly 220 for multiple crushing, thereby ensuring that the copper-containing waste is completely crushed.

[0052] It should be noted that, in this embodiment, when there are two connecting members, the first connecting member 232 and the second connecting member 233 are symmetrically distributed on the rotating shaft 231 .

[0053] Furthermore, in order to facilitate driving the rotating shaft 231 to rotate, the flip assembly 230 also includes a second driving member 236. The second driving member 236 is disposed in the accommodating spacer 250, and the output end of the second driving member 236 is connected to the rotating shaft 231 so as to drive the rotating shaft 231 to move through the second driving member 236. It should be noted that the second driving member 236 can also adopt a servo motor.

[0054] In addition, to facilitate the smelting of copper-containing waste, in this embodiment, the smelting device 300 includes a smelting furnace 310 rotatably connected to the bracket 100, and a third driving member 311 for driving the smelting furnace 310 to rotate; wherein, a gap is provided between the smelting furnace 310 and the cylinder 210 for the smelting furnace 310 to flip, and the inlet and outlet ports 212 of the smelting furnace 310 are arranged opposite to each other.

[0055] Specifically, the third driving component 311 can be a servo motor, so that when the copper-containing waste in the smelting furnace 310 is liquefied into copper water, the third driving component 311 can drive the smelting furnace 310 to flip, and the copper water can be output to an external shaping mold, thereby completing the recycling of the copper-containing waste.

[0056] In summary, the energy-saving regeneration smelting system for copper-containing waste provided by the first embodiment of the present invention has at least the following beneficial effects compared with the traditional smelting method for copper-containing waste:

[0057] In a copper-containing waste energy-saving regeneration smelting system provided by the present invention, a crushing device 200 is arranged in the smelting system, so that the copper-containing waste of different sizes can be crushed by the crushing assembly 220 in the cylinder 210, so that the copper-containing waste of different sizes can be crushed into fine copper-containing waste, and finally the crushed copper-containing waste is filtered by the filter screen 240 located at the discharge port 212 of the cylinder 210, so that the copper-containing waste finally entering the smelting device 300 has the same size, so as to realize the rapid smelting of the copper-containing waste in a short time, and because in the present application, the copper-containing waste of different sizes is first crushed and then smelted after screening, so that when the initial state and the smaller size are Copper-containing waste will not be gasified, which maximizes the utilization rate of copper-containing waste. In addition, due to the certain ductility of copper-containing waste, it cannot be broken into fine copper-containing waste after one crushing, so that some larger copper-containing waste will accumulate on the top of the filter 240. In this application, the flip component 230 can be used to throw the copper-containing waste at the bottom and middle of the cylinder 210 to the top of the cylinder 210, that is, the larger copper-containing waste can be crushed again, and the cycle is repeated until all copper-containing wastes can pass through the holes of the filter 240, thereby ensuring the maximum utilization of copper-containing waste and avoiding the gasification of some copper-containing waste.
