Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrolytic copper, in particular to a conveying device and a crushing conveying system based on a split-type residual anode plate. BACKGROUND

[0002] In the production of electrolytic copper, the anode is cast from crude copper with a copper content of more than 98%, and the cathode is a stainless steel plate; in an electrolytic cell with sulfuric acid and copper sulfate as electrolyte, after power-on, the anode undergoes oxidation reaction: copper in crude copper loses electrons to dissolve into copper ions (Cu - 2e⁻ = Cu²⁺), and the copper ions migrate to the cathode through the electrolyte and are reduced to pure copper (Cu²⁺ +2e⁻ = Cu). As the electrolysis process continues, the anode copper plate continuously dissolves and thins, and when it reaches the preset operating period (usually determined according to the initial thickness of the anode, electrolysis current density, etc.), the electrolytic cell needs to be stopped, at which time the residual anode plate (referred to as residual plate) remaining in the cell is not completely dissolved.

[0003] Referring to Figure 5 , the processing of residual plates needs to be transported, washed, weighed, and then crushed by a crusher 002, and then passed into a smelting furnace 005, at the same time, limestone in a lime hopper 004 falls into the material channel 003 and is finally transported into the smelting furnace, and finally the anode plate is recast; for conventional residual plates, such as the one disclosed in CN118289423A, a modularized automatic storage and transportation system for copper electrolysis residual anode, the anode plate is often integrally cast, with ears on the upper left and upper right, the ears are made of crude copper, and the ears are used to hang the anode plate on the electrolytic cell and conduct electricity; it should be noted that the ear part is not immersed in the electrolyte, so that the copper ions in the ear part do not change during the electrolytic copper process and the formation of the residual plate; but for the residual plate, the ear and the plate body need to be crushed and then melted and cast, i.e. the ear part with unchanged copper ions is melted multiple times, and the heat energy of the melted part of the ear is unnecessary, causing waste of energy.

[0004] In summary, in the process of electrolytic copper, how to realize the melting and recasting of the plate body in the residual plate has become a problem that researchers in the field need to solve. SUMMARY

DETAILED DESCRIPTION

[0016] The application will be further described below in combination with the drawings and examples. These drawings are all simplified schematic diagrams, and only schematically show the basic structure of the application, and thus only show the components related to the application.

[0017] Reference should be made to 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. 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.

[0018] 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. 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. 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 groove 13. At this time, the ear part 2 and the plate 1 are separated.

[0019] See Figure 1 , 2In some possible embodiments, in order to avoid the disengagement of the guide rod from the two ears, the present embodiment is provided with a guide hole 6 transversely penetrating through the ear 2, which is distributed as an inner small-diameter section 61 and an outer large-diameter section 62, the end of the guide rod 3 penetrates through the small-diameter section 61 and is located at the large-diameter section 62, and the end of the guide rod 3 is provided with a limiting ring 7; when the ear 2 is connected with the plate body 1, the limiting ring 7 is in abutment with the stepped surface formed between the small-diameter section 61 and the large-diameter section 62. In the present embodiment, when the ear 2 is connected with the plate body 1, the limiting ring 7 is in contact with the stepped surface, thereby avoiding the axial disengagement of the guide rod 3 from the ear 2.

[0020] Referring to Figure 4 The conveying device 001 in the present solution comprises two parallel conveying belts 02, which can adopt the structure of a rotary sprocket, two ears 2 are in contact with the corresponding conveying belts 02, the residual pole plate 01 is hung on the conveying belts 02, and is transported; a guide section 03 is arranged outside the corresponding conveying belt 02 and is parallel to the length direction of the conveying belt 02 in the length direction; a closing section 04 is arranged at the end of the guide section 03 and is located at the inlet of the conveying belt 02, and the distance between the two opposite closing sections 04 gradually decreases in the movement direction of the conveying belt 02; the ear 2 is transported along the conveying belt 02 and is in contact with the closing section 04 at the outer side end of the ear 2, the two ears 2 gradually approach to be in contact with the guide section 03 at the outer side end of the ear 2, and the plate body 1 is disengaged from the ear 2. In the present embodiment, the ear 2 is supported on the corresponding conveying belt 02, the two conveying belts 02 synchronously move to drive the ear 2 to move linearly, when the outer side end of the ear 2 is in contact with the closing section 04, the two ears 2 approach to each other, the elastic member 4 is compressed to be disengaged from the sliding block 22 and the sliding groove 13, at this time, the plate body 1 falls under the influence of its own weight into the pulverizer below the conveying belt 02, the pulverizer pulverizes the plate body 1 for subsequent melting, and the ear 2 is continuously conveyed to the outlet by the conveying belt 02 and is taken out by a mechanical arm, which is convenient for subsequent cooperation of the ear 2 with other recast plate bodies 1.

[0021] Referring to Figure 4 In some possible embodiments, the conveying belt 02 is provided with baffles 05 at equal intervals; the two adjacent baffles 05 are used for limiting the ear 2. The baffle 05 is fixed on the chain link, the ear 2 is limited between the two baffles 05, the residual pole plate 01 is limited to vertically transport on the conveying belt 02, and it is ensured that the two ears 2 always maintain a vertical state without deviation in the transportation process; it should be noted that the residual pole plate 1 can be hung between the two baffles 05 by a hoisting mechanism for limiting.

[0022] Referring to Figure 4 In some possible embodiments, in order to facilitate the ears to be taken out from the outlet of the conveying belt, the embodiment is provided with flared sections 06 near the outlet of the conveying belt 02, and the distance between the opposite flared sections 06 gradually increases in the direction of movement of the conveying belt 02. In the embodiment, the elastic member 4 is in a compressed state during the ears 2 pass through the guide section 03; when the ears 2 pass through the flared section 06, the elastic member 4 gradually elongates, and the two ears 2 gradually move away from each other, at which time the mechanical arm at the outlet can easily grab the ears.

[0023] Referring to Figure 4 In some possible embodiments, in order to better realize the cooperation between the outer side end of the ear and the converging section, the embodiment is provided with a guide slope 23 on the outer side end of the ear 2, which matches the converging section 04. In the embodiment, the inner side wall at the converging section is in an inclined state, and the inner side wall of the converging section 04 is in surface contact with the guide slope 23, so as to ensure that the two ears 2 can gradually shrink inward.

[0024] It should be noted that, since the plate body 1 is in contact with the inner side wall of the conveying belt 02 on both sides for limiting, when the two ears 2 move to the middle of the avoidance 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, and the situation that only one ear 2 is separated from the plate body 1 and the other ear 2 is not separated from the plate body 1 occurs.

[0025] Referring to Figure 2 The outer end top surface of the sliding block 22 is provided with a chamfer 24, and the chamfer 24 is arranged to gradually separate the sliding groove 13 from the sliding block 22 to the opening of the sliding groove 13 and contact the chamfer of the sliding block 22 when the plate body 1 needs to be separated from the ear 2, at which time the elastic member 4 can be compressed by relying on the gravity of the plate body 1 and the cooperation with the chamfer 24, instead of only relying on the converging section 04 to compress the elastic member 4.

[0026] Referring to Figure 5 The embodiment also discloses a crushing and conveying system, which comprises a crusher 002, the connection position of the converging section 04 and the guide section 03 is above a feeding port of the crusher 002, a smelting furnace 005 is arranged on the right side of the crusher 002, a material channel 003 is arranged between the outlet of the crusher 002 and the inlet of the smelting furnace 005, and a lime hopper 004 is arranged on the left side of the crusher 002 and is used for feeding limestone into the smelting furnace 005 as a slagging agent through the material channel.

[0027] The residual electrode plate split conveying device 001 is arranged directly above the crusher 002. Specifically, the connecting position of the guide section 03 and the closing section 04 of the residual electrode plate split conveying device is directly above the top material dropping port of the crusher 002. After the plate body 1 is separated from the lug 2, the plate body 1 falls into the crusher 002 from the material dropping port under the action of gravity, and the crusher 002 crushes the plate body 1, which is then conveyed into the smelting furnace 005 through the material channel 003.

[0028] Based on the above ideal embodiments of the present application, the above description can be varied and modified without deviating from the technical concept of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined according to the scope of the claims.
