A copper dissolving device with built-in efficiency-improving net cage

Abstract

This invention discloses a copper dissolving device with a built-in efficiency-enhancing mesh box for easy cleaning, belonging to the technical field of copper dissolving equipment. Through the rotation of a gear ring, the device drives a connecting shaft and externally spirally arranged blades to rotate at high speed. The blades interact with the grooves on the inner wall of the crushing box to create a shearing action, quickly crushing the input copper foil into small fragments. These fragments are then dispersed in the gaps between the inner and outer mesh boxes. As the crushing box continues its circular motion, its placement position changes continuously, allowing for multi-directional and uniform distribution of the crushed copper foil fragments into the gaps between the inner and outer mesh boxes. This overcomes the problem of localized accumulation caused by a single placement location, ensuring that all copper foil fragments are dispersed throughout the dissolving area. This method abandons the traditional method of stacking copper foil for dissolving, improving the uniformity of the dissolution concentration and increasing efficiency while meeting the needs of large-scale, high-efficiency production.

Description

Technical Field

[0001] This invention belongs to the technical field of copper melting equipment, and particularly relates to a copper melting device with a built-in efficiency-enhancing mesh box for easy cleaning. Background Technology

[0002] Copper dissolving equipment is a key piece of equipment in the fields of copper foil production and copper material processing, which realizes the dissolution of copper foil to prepare core products such as copper salt solution and copper electrolyte. Its working efficiency and ease of operation are directly related to the overall progress and cost control of subsequent production processes.

[0003] In existing technologies, conventional copper melting vessels mostly adopt a single-cavity structure. During operation, copper foil needs to be added into the copper melting vessel along with the copper foil, so that the copper foil is directly piled at the bottom of the inner cavity of the copper melting vessel for dissolution. After the copper foil is piled up, the contact area between the bottom copper foil and the copper melting medium is greatly compressed, and the circulation path of the medium is blocked, resulting in a slow dissolution rate of the bottom copper foil. Although the upper copper foil has relatively sufficient contact, it is prone to incomplete dissolution due to uneven local dissolution concentration. The overall copper melting cycle is significantly lengthened, making it difficult to meet the needs of large-scale, high-efficiency production. In order to solve the above problems, there is an urgent need for a copper melting vessel with a built-in efficiency-enhancing mesh box that is easy to clean. Summary of the Invention

[0004] The purpose of this invention is to address the problem that after copper foil is stacked, the contact area between the bottom copper foil and the copper dissolving medium is greatly reduced, the circulation path of the medium is blocked, resulting in a slow dissolution rate of the bottom copper foil, while the upper copper foil, although in relatively sufficient contact, is prone to incomplete dissolution due to uneven local dissolution concentration. Therefore, this invention proposes a copper dissolving device with a built-in efficiency-enhancing mesh box for easy cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A copper melting device with a built-in efficiency-enhancing mesh cage for easy cleaning includes: a copper melting tank, a base installed at the bottom of the copper melting tank and communicating with it, and an end cap installed at the top of the copper melting tank. The edge of the end cap is fixed to the copper melting tank by several bolts. A mesh plate is fixedly installed at the opening at the top of the base. A cage-type assembly is attached to the mesh plate. An inlet pipe is connected through the middle of the cage-type assembly. The bottom end of the inlet pipe passes through the mesh plate and the bottom of the base and is connected to a liquid injection assembly. A drive assembly is fixedly installed at the top of the end cap. The bottom end of the drive assembly penetrates the end cap and extends into the interior of the copper melting tank. Crushing boxes are fixedly connected to both sides of the bottom of the drive assembly. The bottom opening of the crushing box is located above the cage-type assembly. A hopper is connected to the top of the crushing box. The hopper penetrates the opening at the bottom of the end cap. Crushing components are installed inside the crushing box. One end of each of the two crushing components penetrates the crushing box and is engaged with a toothed ring. The toothed ring is fixedly connected to the upper part of the inner wall of the copper melting tank. Several grooves are provided on both sides of the inner wall of the crushing box corresponding to the positions of the crushing components.

[0006] As a further description of the above technical solution:

[0007] Handles are fixedly connected to the front and rear sides of the end cap, and feeding covers are installed on the two sides of the top of the end cap corresponding to the positions of the two hoppers. An observation port is provided on the outside of the copper melting tank, and a discharge valve is connected to the lower part of the outside of the base.

[0008] As a further description of the above technical solution:

[0009] The cage-type assembly includes an outer mesh box, with a disc fixed to the bottom of the outer mesh box. The disc has several circular holes. The bottom of the disc overlaps with the bottom of the copper melting tank and the mesh plate. Several limiting posts are fixed at the edge of the bottom of the disc. The limiting posts are inserted into slots in the bottom of the copper melting tank.

[0010] As a further description of the above technical solution:

[0011] The outer mesh cage is equipped with an outer stainless steel mesh cover, and the top opening of the outer mesh cage is equipped with a grid. Hanging rings are fixed around the four sides of the outer mesh cage.

[0012] As a further description of the above technical solution:

[0013] An inner mesh box is located at the center of the outer mesh box. The bottom of the inner mesh box is fixed to the disc. An inner stainless steel mesh cover is provided in the inner mesh box. A central cylinder is located at the center of the inner mesh box. The bottom end of the central cylinder is fixed to the disc. The top end of the inlet pipe passes through the disc and is located inside the central cylinder.

[0014] As a further description of the above technical solution:

[0015] The injection assembly includes a pump body, with a sulfuric acid inlet pipe and a guide pipe connected to both ends of the pump body, and a metering valve installed at the other end of the guide pipe. The end of the metering valve is connected to the inlet pipe.

[0016] As a further description of the above technical solution:

[0017] The drive assembly includes a motor mounted on the end cover. The output shaft of the motor is fixedly connected to a central shaft. A support bearing is rotatably sleeved on the outside of the central shaft. The support bearing is snapped into the middle of the end cover. The bottom end of the central shaft passes through the end cover and is fixedly mounted on a fixing frame. The two sides of the fixing frame are fixedly connected to the opposite sides of the two crushing boxes.

[0018] As a further description of the above technical solution:

[0019] The crushing assembly includes a connecting shaft, the two ends of which are rotatably connected to the crushing box via bushings. One end of the connecting shaft passes through the crushing box and is fixedly connected to a gear. The gear meshes with a gear ring. The outside of the connecting shaft is provided with several blades, which are arranged in a spiral shape and the position of each blade corresponds to the position of the cutting groove.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the fixed frame drives the two crushing boxes on both sides to rotate synchronously. Because the gears of the crushing assembly mesh with the gear ring fixed to the inner wall of the copper melting tank, the gears rotate under the action of the gear ring during the rotation of the crushing box. This, in turn, drives the connecting shaft and the externally spirally arranged blades to rotate at high speed. The blades cooperate with the grooves on the inner wall of the crushing box to form a shearing action, quickly crushing the input copper foil into small fragments, preventing the copper foil fragments from being too large and accumulating. The crushed copper foil fragments fall from the bottom opening of the crushing box into the cage-like assembly below, dispersing in the gap between the inner and outer mesh boxes. The crushing box... During the revolution, the bottom opening always faces the cage-shaped component. As the circular motion continues, the placement position of the crushing box changes continuously, allowing for the placement of crushed copper foil fragments into the gaps between the inner and outer mesh cages from multiple directions and evenly. This breaks the problem of local accumulation caused by a single placement position. As the copper foil fragments are evenly dispersed in the gaps between the inner and outer mesh cages under the action of gravity, all copper foil fragments can be dispersed in all dissolution areas. This eliminates the need for the traditional method of dissolving copper foil by stacking, improves the uniformity of the dissolution concentration, and enhances efficiency while meeting the needs of large-scale and high-efficiency production. 2. In this invention, by starting the pump, external sulfuric acid solution enters the pump through the sulfuric acid inlet pipe. After being pressurized, it is delivered to the metering valve through the conduit pipe. The metering valve precisely controls the sulfuric acid flow rate according to the copper dissolution requirements. Subsequently, the sulfuric acid is delivered to the central cylinder of the cage-type assembly through the inlet pipe and finally overflows from the top opening of the central cylinder. After overflowing, the sulfuric acid solution diffuses radially around the central cylinder, penetrating the inner stainless steel mesh cover, the space between the inner and outer mesh boxes, and the outer stainless steel mesh cover in sequence, uniformly covering the internal area of ​​the cage-type assembly, forming a central guiding and full-area coverage medium circulation mode, ensuring that the subsequently crushed copper foil can fully contact the sulfuric acid. Moreover, undissolved copper foil residue, reaction by-products, and other impurities are intercepted by the outer and inner stainless steel mesh covers of the cage-type assembly and cannot enter the base and copper dissolution medium flow pipeline. Using the lifting rings fixed around the outer mesh box, the entire cage-type assembly is lifted out of the copper dissolution tank as a whole. There is no need to disassemble the copper dissolution tank, the base, and the crushing assembly. The lifted-out cage-type assembly can be directly rinsed and cleaned, and impurities can be collected and treated centrally. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In its specific implementation, such as Figures 1-7 The present invention provides a technical solution:

[0025] A copper melting device with a built-in efficient mesh cage for easy cleaning includes: a copper melting tank 1, a base 2 installed at the bottom of the copper melting tank 1 and connected thereto, and an end cap 3 installed at the top of the copper melting tank 1. The edge of the end cap 3 is fixed to the copper melting tank 1 by several bolts. Handles 14 are fixedly connected to the front and rear sides of the end cap 3 respectively. By unscrewing the bolts on the edge of the end cap 3 and using the handles 14 fixed to the front and rear sides of the end cap 3, the end cap 3 can be removed from the top of the copper melting tank 1, thereby facilitating daily maintenance of the internal structure of the copper melting tank 1.

[0026] Feeding covers 15 are installed on both sides of the top of the end cap 3, corresponding to the positions of the two hoppers 10. An observation port 17 is provided on the outside of the copper melting tank 1. A discharge valve 16 is connected to the lower part of the outside of the base 2. Through the observation port 17 provided on the outside of the copper melting tank 1, the dissolution progress of the copper foil fragments and the state of the sulfuric acid solution in the tank can be viewed in real time, and abnormalities can be detected and dealt with in a timely manner.

[0027] A mesh plate 4 is fixedly installed at the opening at the top of the base 2. A cage-type component 5 overlaps on the mesh plate 4. An inlet pipe 6 is connected through the middle of the cage-type component 5. The cage-type component 5 includes an outer mesh box 501. A disc 502 is fixed at the bottom of the outer mesh box 501. Several circular holes 503 are opened in the disc 502. The bottom of the disc 502 overlaps with the bottom of the copper melting tank 1 and the mesh plate 4. Several limiting posts 506 are fixed at the edge of the bottom of the disc 502. Positioning posts 506 are inserted into slots at the bottom of the copper melting tank 1. By attaching the cage-type assembly 5 above the mesh plate 4, the disc 502 at the bottom of the outer mesh box 501 is tightly fitted with the mesh plate 4 and the bottom of the copper melting tank 1. At the same time, several positioning posts 506 at the bottom edge of the disc 502 are inserted into the pre-set slots at the bottom of the copper melting tank 1, so as to achieve dual circumferential and axial positioning of the cage-type assembly 5 and prevent rotation and displacement problems in subsequent copper melting and crushing operations.

[0028] The outer mesh box 501 is equipped with an outer stainless steel mesh cover 504, and the top opening of the outer mesh box 501 is equipped with a grid 505. The grid 505 facilitates the uniform distribution of copper foil and improves the copper dissolving efficiency. Lifting rings 507 are fixed around the outer mesh box 501. Using the lifting rings 507 fixed around the outer mesh box 501, the entire cage assembly 5 is lifted out of the copper dissolving tank 1. At this time, the undissolved copper foil residue, reaction impurities, etc. are all concentrated in the gap between the inner mesh box 508 and the outer mesh box 501 of the cage assembly 5, which facilitates the cleaning of residues and impurities.

[0029] An inner mesh box 508 is located at the center of the outer mesh box 501. The bottom of the inner mesh box 508 is fixed to the disc 502. An inner stainless steel mesh cover 509 is located in the inner mesh box 508. A central cylinder 510 is located at the center of the inner mesh box 508. The bottom end of the central cylinder 510 is fixed to the disc 502. The top end of the inlet pipe 6 passes through the disc 502 and is located inside the central cylinder 510. Sulfuric acid is transported to the central cylinder 510 of the cage assembly 5 through the inlet pipe 6 and finally overflows from the top opening of the central cylinder 510. After the sulfuric acid solution overflows, it diffuses radially in all directions along the central cylinder 510, and successively penetrates the inner stainless steel mesh cover 509, the space between the inner mesh box 508 and the outer mesh box 501, and the outer stainless steel mesh cover 504, evenly covering the internal area of ​​the cage assembly 5, so that the copper foil can fully contact the sulfuric acid and improve the dissolution effect.

[0030] The bottom end of the inlet pipe 6 passes through the bottom of the mesh plate 4 and the base 2 and is connected to the liquid injection component 7. The liquid injection component 7 includes a pump body 701. The two ends of the pump body 701 are respectively connected to a sulfuric acid inlet pipe 702 and a guide pipe 703. The other end of the guide pipe 703 is equipped with a metering valve 704. The end of the metering valve 704 is connected to the inlet pipe 6. The injection flow rate of the sulfuric acid solution can be flexibly adjusted through the metering valve 704 of the liquid injection component 7 to achieve precise control of the copper dissolving process.

[0031] A drive assembly 8 is fixedly installed on the top of the end cover 3. The bottom end of the drive assembly 8 penetrates the end cover 3 and extends into the interior of the copper melting tank 1. Crushing boxes 9 are fixedly connected to both sides of the bottom of the drive assembly 8. The bottom opening of the crushing box 9 is located above the cage-type assembly 5. A hopper 10 is connected to the top of the crushing box 9. The hopper 10 penetrates the bottom opening of the end cover 3. The drive assembly 8 includes a motor 801, which is mounted on the end cover 3. The output shaft of the motor 801 is fixedly connected to a central shaft 803. A support bearing 802 is rotatably sleeved on the outside of the central shaft 803. The central shaft 803 is snapped into the middle of the end cover 3. The bottom end of the central shaft 803 passes through the end cover 3 and is fixed with a fixing frame 804. The two sides of the fixing frame 804 are fixedly connected to the opposite surfaces of the two crushing boxes 9. The output shaft of the motor 801 drives the central shaft 803 to rotate. The central shaft 803 maintains stable rotation under the support of the support bearing 802. At the same time, the fixing frame 804 drives the crushing boxes 9 on both sides to revolve synchronously. Since the crushing component 11 is meshed with the gear ring 13, the crushing component 11 can work synchronously when the crushing boxes 9 revolve, without the need to provide an additional power source for the crushing component 11, thus reducing the cost of use.

[0032] The crushing box 9 is equipped with crushing components 11. One end of each of the two crushing components 11 passes through the crushing box 9 and is engaged with a toothed ring 13. The toothed ring 13 is fixedly connected to the upper part of the inner wall of the copper melting tank 1. Several grooves 12 are provided on both sides of the inner wall of the crushing box 9 corresponding to the positions of the crushing components 11.

[0033] The crushing assembly 11 includes a connecting shaft 111. Both ends of the connecting shaft 111 are rotatably connected to the crushing box 9 via bushings. One end of the connecting shaft 111 passes through the crushing box 9 and is fixedly connected to a gear 112. The gear 112 meshes with a gear ring 13. Several blades 113 are arranged spirally on the outside of the connecting shaft 111, and the position of each blade 113 corresponds to the position of the cutting groove 12. When the crushing box 9 revolves, the gear 112 rotates under the action of the gear ring 13, thereby driving the connecting shaft 111... The shaft 111 and the spirally arranged blades 113 rotate at high speed. The blades 113 cooperate with the grooves 12 on the inner wall of the crushing box 9 to form a shearing action, which quickly crushes the copper foil into small fragments and avoids the copper foil fragments from being too large and accumulating. During the revolution, the bottom opening of the crushing box 9 always faces the cage-type component 5. As the circular motion continues, the placement position of the crushing box 9 changes continuously, which can place the crushed copper foil fragments into the gap between the inner mesh box 508 and the outer mesh box 501 in multiple directions and evenly.

[0034] Working principle:

[0035] By fixing the mesh plate 4 to the opening connecting the bottom of the copper melting tank 1 and the base 2, it serves as a stable support surface for the cage-type component 5. Then, the cage-type component 5 is overlapped on top of the mesh plate 4, so that the disc 502 at the bottom of the outer mesh box 501 fits tightly with the mesh plate 4 and the bottom of the copper melting tank 1. At the same time, several limiting posts 506 on the bottom edge of the disc 502 are inserted into the preset slots at the bottom of the copper melting tank 1, so as to achieve dual circumferential and axial positioning of the cage-type component 5 and prevent rotation and displacement problems in subsequent copper melting and crushing operations. Next, the feeding cover 15 on the top of the end cover 3 is opened, and the copper foil to be dissolved is put into the crushing box 9 through the hopper 10. After the feeding is completed, the feeding cover 15 is closed. The copper foil that does not enter the crushing box 9 is temporarily stored in the hopper 10. When the drive component 8 is not started, the copper foil is also temporarily stored in the crushing box 9, waiting for crushing, to avoid the copper foil directly entering the bottom of the copper melting tank 1 and causing stacking.

[0036] By activating the pump body 701 of the injection component 7, the external sulfuric acid solution enters the pump body 701 through the sulfuric acid connection pipe 702. After being pressurized, it is delivered to the metering valve 704 through the guide pipe 703. The metering valve 704 precisely controls the sulfuric acid flow rate according to the copper dissolution requirements. Subsequently, the sulfuric acid is delivered to the central cylinder 510 of the cage component 5 through the inlet pipe 6. Finally, it overflows from the top opening of the central cylinder 510. After the sulfuric acid solution overflows, it spreads radially around the central cylinder 510, and in turn, it penetrates the inner stainless steel mesh cover 509, the space between the inner mesh box 508 and the outer mesh box 501, and the outer stainless steel mesh cover 504, uniformly covering the internal area of ​​the cage component 5.

[0037] Next, the motor 801 of the drive assembly 8 is started. The output shaft of the motor 801 drives the central shaft 803 to rotate. The central shaft 803 maintains stable rotation under the support of the support bearing 802. At the same time, the fixed frame 804 drives the crushing boxes 9 on both sides to revolve synchronously. Since the gear 112 of the crushing assembly 11 meshes with the gear ring 13 fixed on the inner wall of the copper melting tank 1, when the crushing box 9 revolves, the gear 112 rotates under the action of the gear ring 13, which in turn drives the connecting shaft 111 and the blades 113 arranged in a spiral shape to rotate at high speed. The blades 113 cooperate with the grooves 12 on the inner wall of the crushing box 9 to form a shearing action, which quickly crushes the copper foil into small fragments, avoiding the copper foil fragments from being too large and accumulating. The crushed copper foil fragments fall from the bottom opening of the crushing box 9 into the cage assembly 5 below, and are dispersed in the gap between the inner mesh box 508 and the outer mesh box 501.

[0038] During its revolution, the crushing box 9 always keeps its bottom opening facing the cage-shaped component 5. As the circular motion continues, the placement position of the crushing box 9 changes continuously, enabling it to place the crushed copper foil fragments into the gap between the inner cage 508 and the outer cage 501 from multiple directions and evenly. This breaks the problem of local accumulation caused by a single placement position. As the copper foil fragments are evenly dispersed in the gap between the inner cage 508 and the outer cage 501 under the action of gravity, all copper foil fragments can be dispersed in all dissolution areas.

[0039] During the dissolution process, the dissolution progress of copper foil fragments and the state of sulfuric acid solution can be observed in real time through the observation port 17 set on the outside of the copper dissolution tank 1. Abnormalities can be detected and dealt with in a timely manner. The injection flow rate of sulfuric acid solution can be flexibly adjusted by the metering valve 704 of the injection component 7 to achieve precise control of the copper dissolution process. The copper electrolyte generated by the dissolution of copper foil fragments will pass through the outer stainless steel mesh cover 504 of the outer mesh box 501, several round holes 503 on the disc 502, and the mesh plate 4 in sequence, and finally converge into the interior of the base 2. Incompletely dissolved copper foil residue, reaction by-products and other impurities are intercepted by the outer stainless steel mesh cover 504 and the inner stainless steel mesh cover 509 of the cage component 5 and cannot enter the base 2 and the copper dissolution medium flow pipeline. When the copper dissolution operation is completed and the copper electrolyte reaches the preset standard, the discharge valve 16 connected to the bottom of the outside of the base 2 can be opened to export the prepared qualified copper electrolyte to the subsequent production process, realizing convenient and rapid discharge of electrolyte.

[0040] After the copper melting operation is completed, wait for the internal pressure of the copper melting tank 1 to drop to normal pressure and the temperature to return to normal. Unscrew several bolts on the edge of the end cover 3 and remove the end cover 3 from the top of the copper melting tank 1 using the handles 14 fixed on the front and back sides of the end cover 3. Then, use the lifting rings 507 fixed around the outer mesh box 501 to lift the entire cage assembly 5 out of the copper melting tank 1. At this time, the undissolved copper foil residue, reaction impurities, etc. are all concentrated in the gap between the inner mesh box 508 and the outer mesh box 501 of the cage assembly 5. There is no need to disassemble the copper melting tank 1, the base 2, and the crushing component 11. After cleaning, the cage assembly 5 is re-stablely attached to the mesh plate 4, ensuring that the limit post 506 is inserted into the slot. Reset the end cover 3 and tighten the bolts. Check the connection of each component and complete the equipment maintenance and reset. The next round of copper melting operation can then be started.
