Description

Technical Field

[0001] This invention relates to the field of electrolytic copper, and in particular to a conveying device and crushing and conveying system based on a split-type residual electrode plate. Background Technology

[0002] In electrolytic copper production, the anode is cast from crude copper with a copper content greater than 98%, while the cathode is a stainless steel plate. In an electrolytic cell using sulfuric acid and copper sulfate as electrolytes, an oxidation reaction occurs at the anode after electricity is applied: the copper in the crude copper loses electrons and dissolves into copper ions (Cu - 2e⁻ = Cu²⁺). The copper ions migrate through the electrolyte to the cathode and are reduced to pure copper (Cu²⁺ + 2e⁻ = Cu). As the electrolysis process continues, the anode copper plate gradually dissolves and becomes thinner. When the preset operating cycle is reached (usually determined based on parameters such as the initial thickness of the anode and the electrolytic current density), the electrolytic cell must be stopped. The remaining incompletely dissolved anode plate in the cell at this time is called the copper residual anode plate (or simply residual plate).

[0003] See Figure 5 The processing of residual anode plates involves transportation, washing, weighing, and then crushing them in crusher 002. The crushed material is then fed into smelting furnace 005 via material channel 003. Simultaneously, limestone from lime hopper 004 falls onto material channel 003 and is ultimately transported to the smelting furnace, where it is remelted and cast into anode plates. For conventional residual anode plates, such as those in publication CN118289423A, entitled "A Modular Automatic Storage and Transportation System for Copper Electrolysis Residual Anodes," the anode plates are often integrally cast, with the upper left corner... There is an ear at the upper right, which is made of crude copper. The function of the ear is to hang the anode plate on the electrolytic cell and pass electricity through it. It should be noted that the ear is not immersed in the electrolyte. This way, the copper ions in the ear will not change during the electrolysis of copper and when the residual electrode plate is formed. However, for the residual electrode plate, the ear and the plate body need to be crushed together and then melted and cast. That is, the ear, which does not change the copper ions, needs to be melted multiple times. The heat energy of melting the ear is unnecessary and results in energy waste.

[0004] In summary, how to achieve melting and recasting of only the plate body in the residual electrode plate during the electrolytic copper process has become an urgent problem for researchers in this field. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to achieve melting and recasting of only the plate body in the residual electrode plate during the electrolytic copper process;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] This invention relates to a conveying device based on a split-type residual electrode plate. The residual electrode plate in this application includes: a plate body, on both sides of its top extending upwards with connecting portions, and a clearance groove formed between the two connecting portions; two ears located at the clearance groove, which are laterally slidably connected to the corresponding connecting portions, with the outer ends of the ears extending out of the plate body; and a guide rod connecting the two ears; when the two ears move relative to each other and approach each other along the guide rod, the two ears are separated from the plate body.

[0008] The conveying device in this application is used to separate the plate body and the ear portion of a split residual electrode plate, comprising: two parallel conveyor belts, with the two ear portions contacting the corresponding conveyor belts, suspending the residual electrode plate on the conveyor belts for lateral transport; a guide section disposed on the outer side of the corresponding conveyor belt, with its length direction parallel to the length direction of the conveyor belt; and a closing section disposed at the end of the guide section and located at the entrance of the conveyor belt, with the distance between the two opposite closing sections gradually decreasing along the direction of movement of the conveyor belt; the ear portions are transported along the conveyor belt and contact the outer ends of the ear portions with the closing sections, the two ear portions gradually approaching each other until the outer ends of the ear portions contact the guide section, and the plate body detaches from the ear portions.

[0009] Furthermore, the inner wall of the connecting part is provided with a groove extending outward; a slider is provided at the ear and inserted into the groove; an elastic element is sleeved on the guide rod, and the end of the elastic element contacts the inner wall of the ear.

[0010] Furthermore, a guide hole is provided transversely on the ear portion, the guide hole being distributed as a small diameter section on the inner side and a large diameter section on the outer side, the end of the guide rod passing through the small diameter section and located at the large diameter section, and the end of the guide rod being provided with a limiting part; when the ear portion is in a connected state with the plate body, the limiting ring abuts against the stepped surface formed between the small diameter section and the large diameter section.

[0011] Furthermore, partitions are evenly spaced on the conveyor belt; adjacent partitions are used to limit the position of the ear.

[0012] Furthermore, the guide section is provided with a flared section near the outlet of the conveyor belt, and the distance between two opposite flared sections gradually increases along the direction of movement of the conveyor belt.

[0013] Furthermore, the outer end of the ear has a guide slope that matches the closing section.

[0014] Furthermore, a chamfer is provided on the top surface of the outer end of the slider.

[0015] This application also discloses a crushing and conveying system, including: a crusher, wherein the connection between the closing section and the guide section is located above the feed port of the crusher; a smelting furnace, which is disposed on one side of the crusher, and the outlet of the crusher is connected to the inlet of the smelting furnace through a material channel; and a lime hopper, which is disposed on one side of the crusher, and the lime hopper feeds limestone into the smelting furnace through the material channel.

[0016] The beneficial effects of this invention are as follows: This invention is based on a conveying device and a crushing and conveying system for a split-type residual electrode plate. When the two ears move linearly on the conveying device, they also move axially toward the center along the guide rod. After the two ears separate from the corresponding connecting parts, the plate body separates from the ears and automatically falls to the crusher below under its own weight. This facilitates subsequent melting and recasting of only the plate body, saving the heat energy of melting and recasting the ears and reducing energy consumption. In addition, the ears can be reused and assembled with the plate body generated by subsequent casting to participate in the electrolytic copper process again. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] See Figure 1 , 23. This embodiment is based on a conveying device for a split-type residual electrode plate. The residual electrode plate 01 includes: a connecting part 11 is provided at the upper left and upper right of the top of the plate body 1, and a clearance groove 12 is formed between the two connecting parts 11; two ears 2 are located on the left and right sides of the clearance groove 12 respectively, and the ears 2 are laterally slidably connected to the corresponding connecting parts 11, that is, the ear 2 on the left side of the clearance groove 12 is laterally slidably connected to the connecting part 11 on the left side, and the ear 2 on the right side of the clearance groove 12 is laterally slidably connected to the connecting part 11 on the right side, the outer end 21 of the left ear 2 extends to the outer left side of the plate body 1, and the outer end 21 of the right ear 2 extends to the outer right side of the plate body 1; a guide rod 3 connects the two ears 2, and the guide rod 3 is set so that the ears 2 can move along the axial direction of the guide rod 3; when the two ears 2 move relative to each other and approach each other along the axial direction of the guide rod 3, the two ears 2 are separated from the plate body 1.

[0025] In this embodiment, when the two ears 2 move axially toward the center along the guide rod 3, and the two ears 2 separate from the corresponding connecting part 11, the plate 1 separates from the ears 2 and falls to the crusher under its own weight, which facilitates the subsequent melting and recasting of only the plate 1, saving the heat energy of melting and recasting the ears 2 and reducing energy consumption; in addition, the ears 2 and the connecting part 11 are slidably connected, and the current can still be transmitted to the plate 1 through the ears 2, without affecting the normal electrolytic copper operation.

[0026] In some possible embodiments, to illustrate how the connecting part and the ear are slidably connected, this embodiment uses a groove 13 that is opened outward on the corresponding inner sidewall of the connecting part 11; a slider 22 is provided at the ear 2 and inserted into the groove 13; an elastic element 4 is sleeved on the guide rod 3, and the end of the elastic element 4 contacts the corresponding inner sidewall of the ear 2.

[0027] See Figure 1 In this embodiment, the ear part 2 and the connecting part 11 are connected by a sliding groove 13 and a slider 22. An elastic element 4 is provided between the two ear parts 2. The elastic element 4 releases elastic force, causing the two ear parts 2 to move to both sides until the slider 22 of the ear part 2 is inserted and connected to the sliding groove 13 of the connecting part 1, thus realizing the connection between the ear part 2 and the plate 1.

[0028] See Figure 2 When the ear part 2 needs to be separated from the plate 1, it overcomes the elastic force of the elastic element 4 and moves towards the middle until the slider 22 separates from the slide groove 13. At this time, the ear part 2 and the plate 1 are separated.

[0029] See Figure 1 , 2In some possible embodiments, to prevent the guide rod from detaching from the two ears, this embodiment employs a guide hole 6 that is laterally through the ear 2. The guide hole 6 is distributed as a small diameter section 61 on the inner side and a large diameter section 62 on the outer side. The end of the guide rod 3 passes through the small diameter section 61 and is located at the large diameter section 62. The end of the guide rod 3 is provided with a limiting part 7. When the ear 2 is connected to the plate 1, the limiting ring 7 abuts against the stepped surface formed between the small diameter section 61 and the large diameter section 62.

[0030] In this embodiment, when the ear part 2 is connected to the plate body 1, the limiting ring 7 is in contact with the step surface to prevent the guide rod 3 from axially disengaging from the ear part 2.

[0031] See Figure 4 The conveying device 001 in this solution includes: two parallel conveyor belts 02, which may adopt a rotating sprocket structure; two ears 2 contact the corresponding conveyor belts 02 to suspend the residual plate 01 on the conveyor belts 02 for transportation; a guide section 03 is located on the outer side of the corresponding conveyor belt 02, and its length direction is parallel to the length direction of the conveyor belt 02; a closing section 04 is located at the end of the guide section 03 and at the entrance of the conveyor belt 02, and the distance between the two closing sections 04 gradually decreases along the movement direction of the conveyor belt 02; the ears 2 are transported along the conveyor belt 02 and contact the outer end of the ears 2 with the closing section 04, and the two ears 2 gradually approach each other until the outer end of the ears 2 contacts the guide section 03, at which point the plate 1 detaches from the ears 2;

[0032] In this embodiment, the ear part 2 is supported on the corresponding conveyor belt 02. The two conveyor belts 02 move synchronously, causing the ear part 2 to move in a straight line. When the outer end of the ear part 2 contacts the closing section 04, the two ear parts 2 move closer to each other. The elastic element 4 is compressed until the slider 22 separates from the groove 13. At this time, the plate 1 falls into the crusher below the conveyor belt 02 under its own weight. The crusher crushes the plate 1 for subsequent melting. The ear part 2 is continued to be transported by the conveyor belt 02 to the outlet and taken out by the robotic arm, so that the ear part 2 can be matched with other recast plates 1 in the future.

[0033] See Figure 4 In some possible embodiments, partitions 05 are provided at equal intervals on the conveyor belt 02; adjacent partitions 05 are used to limit the ear portion 2;

[0034] The partition 05 is fixed on the chain link, and the ear 2 is limited between the two partitions 05, restricting the residual electrode plate 01 to be transported vertically on the conveyor belt 02, ensuring that the two ears 2 remain vertical and do not shift during transportation; it should be noted that the residual electrode plate 1 can be hung between the two partitions 05 for limitation by a hoisting mechanism.

[0035] See Figure 4 In some possible embodiments, in order to facilitate the removal of the ear from the outlet of the conveyor belt, this embodiment adopts a flared section 06 provided at the outlet of the guide section 03 near the outlet of the conveyor belt 02, and the distance between the two flared sections 06 gradually increases along the movement direction of the conveyor belt 02.

[0036] In this embodiment, as the ear 2 passes through the guide section 03, the elastic element 4 is in a compressed state; when the ear 2 passes through the flaring section 06, the elastic element 4 gradually elongates and the two ears 2 gradually move away from each other, which makes it easier for the robotic arm at the exit to grab the ear.

[0037] See Figure 4 In some possible embodiments, in order to better achieve the fit between the outer end of the ear and the closing section, this embodiment adopts a guide slope 23 on the outer end of the ear 2 that matches the closing section 04;

[0038] In this embodiment, the inner wall of the closing section is inclined, and the inner wall of the closing section 04 is in surface contact with the guide inclined surface 23 to ensure that the two ears 2 can gradually retract inward.

[0039] It should be noted that since the two sides of the plate 1 are respectively in contact with and limited by the inner side wall of the conveyor belt 02, when the ear 2 moves towards the middle of the clearance groove 12 at the same time, there is no need to worry that one ear 2 moves too much and the other ear 2 moves too little, resulting in only one ear 2 detaching from the plate 1 while the other ear 2 does not detach from the plate 1.

[0040] See Figure 2 The top surface of the outer end of the slider 22 is provided with a chamfer 24. The purpose of the chamfer 24 is that when the plate 1 needs to be separated from the ear 2, the slide groove 13 and the slider 22 gradually separate until the opening of the slide groove 13 contacts the chamfer of the slider 22. At this time, the elastic element 4 can be compressed by the weight of the plate 1 and the cooperation with the chamfer 24. The compression of the elastic element 4 is not only due to the closing section 04, but also due to the weight of the plate 1.

[0041] See Figure 5This embodiment also discloses a crushing and conveying system, including: a crusher 002, wherein the connection between the closing section 04 and the guide section 03 is located above the feeding port of the crusher 002; a smelting furnace 005, which is located on the right side of the crusher 002, and the outlet of the crusher 002 is connected to the inlet of the smelting furnace 005 through a material channel 003; and a lime hopper 004 located on the left side of the crusher 002, wherein the lime hopper 004 feeds limestone into the smelting furnace 005 as a slagging agent through the material channel.

[0042] The residual electrode plate split conveying device 001 is located directly above the crusher 002. Specifically, the connection between the guide section 03 and the closing section 04 in the residual electrode plate split conveying device is located directly above the top discharge port of the crusher 002. In this way, after the plate 1 separates from the ear 2, the plate 1 falls into the crusher 002 from the discharge port under its own weight. The crusher 002 crushes the plate 1 and then conveys it to the smelting furnace 005 through the material channel 003.

[0043] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
