Description

Technical Field

[0001] This invention relates to the field of copper removal slag treatment technology for lead electrolytic anodes, and specifically to a treatment device and method for removing copper slag from lead electrolytic anodes. Background Technology

[0002] The production process of lead electrolytic anodes generates dross containing metals such as copper. If this dross is not properly treated, it will not only waste resources but may also pollute the environment. Currently, there are several technical problems that urgently need to be solved in the treatment of copper-containing dross from lead electrolytic anodes.

[0003] Existing lead electrolysis anode copper removal slag treatment devices and methods often suffer from insufficient slag decomposition. This is because the slag cannot come into uniform contact with the decomposition solution after being added to the treatment device, resulting in low decomposition efficiency and affecting the subsequent treatment effect.

[0004] Moreover, poor filtration and separation efficiency is a significant problem. The existing filtration structure design is not reasonable enough. During the filtration process, the screen holes are easily clogged by scum particles, resulting in slow filtration speed and even requiring frequent shutdowns for cleaning, which seriously affects the continuity of the processing flow and production efficiency.

[0005] Meanwhile, existing equipment lacks an effective sieving mechanism when processing scum. This leads to the accumulation of scum particles during filtration, preventing sufficient grading and resulting in low purity of the final collected product, which is insufficient to meet production requirements.

[0006] Furthermore, existing processing methods suffer from uneven material distribution during the material feeding and dispensing process. This leads to over-treatment of scum in some areas and incomplete treatment in others, further impacting the overall processing quality and efficiency.

[0007] In summary, existing lead electrolytic anode copper slag removal devices and methods have many shortcomings in slag decomposition, filtration and separation, sieving and material distribution, and there is an urgent need for a new type of treatment device and method that can solve the above problems. Summary of the Invention

Adjacent filter screen frames intersect to form triangular holes. An installation groove is provided at the top of the side wall connected to the support tube. Both the filter screen frame and the arc-shaped scraper are curved. The support tube is sleeved on the shaft, and its bottom fits against the fixed sleeve. It is installed between the fixed sleeve and the rotating arm. A slot for engaging with a clip is provided on the outer wall of the support tube. Reinforcing ribs are provided on the outer walls of both the filter screen frame and the filter screen bracket.

[0013] Preferably, the feeding assembly includes an upper sliding cylinder located below the guide inclined plate, with a lower sliding cylinder and a material holding filter frame fixedly connected to its lower end in sequence. The material holding filter frame is located inside the filter screen support. A connecting baffle is fixedly connected between adjacent upper sliding cylinders.

[0016] Preferably, the filter screen outer frame, filter screen support, and material holding filter frame are all cylindrical, and the inner walls of the upper material sliding cylinder and the lower material sliding cylinder are inclined.

[0017] This application also provides a method for treating copper slag removal from lead electrolytic anodes, comprising the following steps:

[0018] S1. Material feeding: Open the sealed cover and feed the copper removal slag from the lead electrolytic anode into the filter assembly inside the shell through the feeding component. The guide plate and the feeding plate work together to make the slag fall evenly.

[0019] S2. Decomposition Processing: Start the drive motor to drive the rotating shaft, clamping strip and scum treatment mechanism to rotate. Collect gas through the gas collection pipe. The scum decomposes in the decomposition liquid. The arc-shaped scraper contacts the blocking strip to generate vibration. The vibration force is transmitted to the filter screen support and the material holding filter frame through the outer and inner force guiding springs to avoid clogging of the screen holes and realize the scum vibration screen.

[0020] S3. Filtration and separation: The decomposed material is filtered step by step through the screen holes of the material holding filter frame, filter screen support and filter screen outer frame, and the liquid enters the shell.

[0021] S4. Product collection: Stop the motor, open the discharge port at the bottom of the shell to collect the liquid, press the rotating arm to remove the scum treatment mechanism and collect the internal particles.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a shell, the present invention provides a closed space for the copper slag removal treatment of lead electrolytic anodes, avoids the leakage of harmful gases, and utilizes the cooperation of its internal structural components to promote the full mixing and reaction of slag and decomposition liquid.

[0023] By setting up a scum distribution mechanism, the scum can be evenly dispersed and guided, avoiding scum clumping and jamming, ensuring uniform and continuous distribution, and providing good conditions for subsequent processing.

[0024] By setting up a scum treatment mechanism, the scum can be efficiently decomposed, filtered, and separated, promoting thorough mixing of the scum and the decomposition liquid, improving decomposition efficiency, and preventing clogging of the screen holes, thus ensuring the continuous operation of the filtration process.

[0025] By combining the slag distribution mechanism and the slag treatment mechanism, the copper removal slag from lead electrolytic anodes is efficiently treated. From the uniform distribution of slag to the continuous operation of decomposition and filtration, a complete and efficient processing flow is formed, which improves processing efficiency and product purity, reduces equipment wear, and extends the service life of the equipment.

Detailed Implementation

[0041] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0042] This embodiment provides a technical solution: a treatment device and method for removing copper slag from lead electrolytic anodes, such as... Figure 1-12 As shown, the device includes a cylindrical shell 11 with a pair of annular grooves 14 fixedly fitted on its outer wall. Multiple evenly distributed vent holes 12 are opened within the annular grooves 14, and a material-blocking mesh 13 is installed within each vent hole 12. The pair of annular grooves 14 are connected by a gas-collecting pipe 15, which is fixed to the outer wall of the shell 11. This design is because harmful gases such as sulfur dioxide may be generated during the copper slag removal process at the lead electrolytic anode. The combination of the annular grooves 14 and the vent holes 12 allows these gases to be collected in a timely manner and transported to the subsequent purification treatment device through the gas-collecting pipe 15, preventing the direct emission of harmful gases into the environment and causing pollution. The material-blocking mesh 13 is made of corrosion-resistant metal, effectively blocking slag particles from entering the vent holes. Its corrosion resistance ensures normal operation even under long-term contact with corrosive gases and liquids, extending the service life of the device.

[0043] A drive motor 16 is fixed below the housing 11 by a mounting bracket. A rotating shaft 17 is provided inside the housing 11 above the motor. The outer wall of the rotating shaft 17 is provided with a circumferentially arranged array of retaining strips 19. A circumferentially arranged array of blocking strips 18 is fixed to the inner wall of the housing. The rotating shaft 17 drives the retaining strips 19 to rotate. When the retaining strips 19 collide with the blocking strips 18, a continuous vibration force is generated. This vibration force is transmitted inside the device. On the one hand, it can promote the full mixing of scum and decomposition liquid, so that the scum particles can come into more comprehensive contact with the decomposition liquid, thereby improving the decomposition efficiency. On the other hand, the vibration acts on the filter assembly 31, which can prevent the screen holes from being blocked by scum particles, ensure the smooth progress of the filtration process, and avoid the problems of reduced processing efficiency and frequent shutdowns for cleaning caused by screen hole blockage.

[0044] The scum distribution mechanism 2 is installed on the top of the main structure 1 and includes a cover plate 21. The top center of the cover plate is connected to the distribution component 22 through a through hole. A sealing cover 23 is provided above the distribution component 22. The cover plate 21 serves to support and fix the distribution component 22. The sealing cover 23 adopts a structure design with good sealing performance. It is opened when the material is fed and closed after the feeding is completed. This not only prevents gas from escaping during the feeding process and maintains a sealed environment inside the device, but also prevents external debris from entering the device and affecting the scum treatment effect.

[0045] The scum treatment mechanism 3 is installed inside the main structure 1 and includes a support pipe 32 fixed on the rotating shaft 17. The support pipe 32 is equipped with a circumferentially arrayed filter assembly 31. Multiple filter assemblies 31 are equipped with a feeding assembly 33. The filter assembly 31 and the feeding assembly 33 work together to decompose and filter the scum step by step. The support pipe 32 and the rotating shaft 17 drive the rotation to ensure that the scum and the decomposition liquid are in full contact.

[0046] The rotating shaft 17 includes a shaft body 171, the lower end of which passes through the bottom of the housing 11 and is fixedly connected to a coupling on the output shaft of the drive motor 16, and is rotatably connected to the housing 11; the outer wall of the top end of the shaft body 171 has multiple circumferentially arranged grooves 172, and a rotating arm 173 is rotatably connected to the grooves through a rotating rod; a wave-shaped spring piece 174 is fixedly connected between the rotating arm 173 and the inner wall of the groove 172; during rotation, the rotating arm 173 can elastically abut against the feeding assembly 33 under the action of centrifugal force and elastic force, providing... The feeding assembly 33 provides dynamic pressure, which helps stabilize the decomposition process of scum. The clamping strip 19 is fixedly connected to the outer wall of the shaft 171. A fixing sleeve located inside the housing 11 is fixedly sleeved on the shaft 171. The fixing sleeve is made of high-strength metal material and fits tightly with the shaft to ensure that the support tube 32 is installed stably and will not shake or shift during rotation, thereby ensuring the normal operation of the filter assembly 31 and the feeding assembly 33 and avoiding the impact of unstable installation on the scum treatment effect.

[0047] like Figure 3 , Figure 4 and Figure 12 As shown, the material distribution assembly 22 includes a funnel body 221 fixedly connected to the central through hole of the cover plate 21. Multiple circularly arranged discharge holes 222 are opened at the bottom of the funnel body 221. A guide plate 223, which is concave at the top and convex at the bottom, is fixedly connected to the bottom of the funnel body 221 at the lower end of each hole. Multiple first convex strips are fixedly connected to the concave surface of the guide plate 223. The inner edge of the funnel body 221 and the area between adjacent discharge holes 222 are all sloped, with the height decreasing from the edge to the center, and the center being convex at the top and concave at the bottom. The edges of the discharge holes 222 are chamfered. A sealing cap 23 is installed inside the funnel body 221. The unique sloped structure of the funnel body 221, with its inner edge and the area between adjacent discharge holes all sloped and with the height decreasing from the edge to the center, creates a unique sloping structure. The structural design allows the scum to slide naturally down the slope under gravity. Due to the uniform height distribution of the slope, the scum will evenly gather towards the center. The concave top and convex bottom shape of the guide plate 223 matches the slope-shaped funnel body 221, further guiding the flow direction of the scum. The multiple first convex strips in the concave surface can effectively break up the gathered scum clumps, preventing scum from clumping and ensuring that the scum can fall evenly into the processing mechanism 3 below through each discharge hole 222, thereby achieving uniform scum delivery and laying a good foundation for subsequent full decomposition. The chamfered design of the edge of the discharge hole 222 can reduce the frictional resistance between the material and the edge of the hole, allowing the scum to pass through the discharge hole more smoothly and avoiding material jamming, further ensuring the uniformity and continuity of material distribution.

[0048] like Figures 4 to 11 As shown, the filter assembly 31 includes a filter screen frame 311 fixedly connected to the outer wall of the support tube 32, and a filter screen support 314 fixedly connected inside it. An arc-shaped scraper 312 that fits against the inner wall of the housing 11 is fixedly connected to the outer end of the filter screen frame 311. The scraper has a weakening groove 313. Curved outer force guiding springs 315 and inner force guiding springs 316 are fixedly connected to the outer and inner walls of the outer end of the filter screen support 314, respectively. When the arc-shaped scraper 312 rotates with the support tube 32, it will collide with the blocking strip 18 on the inner wall of the housing 11. Because the scraper has a weakening groove 313, the scraper will be able to withstand the impact of the friction. The structure of the weakening tank 313 is more prone to deformation during collision, thereby enhancing the vibration effect. The vibration force is transmitted to the filter screen support 314 and the material holding filter frame 333 through the outer force guiding spring 315 and the inner force guiding spring 316. This elastic transmission method can make the vibration evenly distributed on the filter assembly 31, effectively preventing the screen holes from being blocked by scum particles. When scum particles come into contact with the screen, the vibration will prevent the particles from staying and accumulating on the screen, but instead allow them to fall through the screen holes in time, keeping the screen holes unobstructed and ensuring the continuous operation of the filtration process.

[0049] Adjacent filter screen frames 311 form staggered triangular holes, and the top of the side wall connecting to the support tube 32 is provided with an installation groove. Both the filter screen frame 311 and the arc-shaped scraper 312 are curved. The support tube 32 is sleeved on the shaft 171, and its bottom fits against the fixed sleeve. It is installed between the fixed sleeve and the rotating arm 173. The outer wall of the support tube 32 is provided with a slot for engaging with the clip 19. The outer walls of the filter screen frame 311 and the filter screen support 314 are provided with reinforcing ribs. The reinforcing ribs are made of the same high-strength material as the filter screen frame 311 and the filter screen support 314. Through reasonable layout design, the structural strength of the filter assembly 31 can be significantly improved, so that it will not deform or be damaged under long-term vibration and scum pressure, ensuring the stability and reliability of the filter assembly and extending the service life of the device.

[0050] The feeding assembly 33 includes an upper sliding cylinder 331 located below the guide inclined plate 223. A lower sliding cylinder 332 and a material holding filter 333 are sequentially fixedly connected to its lower end. The material holding filter 333 is located within the filter screen support 314. A connecting baffle 334 is fixedly connected between adjacent upper sliding cylinders 331. The upper sliding cylinder 331 and the connecting baffle 334 form a feeding tray that fits against the inner wall of the housing 11. The lower sliding cylinder 332 is inclined, and the upper sliding cylinder 331 is curved. This special shape design is based on... Based on fluid mechanics principles, the inclined sliding material cylinder 332 guides the scum to slide smoothly under gravity, while the curved upward sliding material cylinder 331 adjusts the falling direction of the scum, allowing it to fall evenly into the material collection filter frame 333. The material discharge plate is tightly fitted to the inner wall of the shell 11, and high-precision processing technology ensures a tight fit. This effectively prevents the scum from falling through the gap between the material discharge plate and the shell, avoiding material waste, while ensuring that all the scum enters the material collection filter frame 333 for processing, thus improving processing efficiency.

[0051] A positioning ring 330 is fixedly connected to the center of the feeding tray via a round hole, abutting against the mounting groove. The top of the positioning ring 330 abuts against the bottom of the rotating arm 173, and its lower end is fixedly connected to a guide column 336 inserted into a triangular hole. The guide column 336, inserted into the triangular hole, provides good positioning and stabilization, ensuring that the feeding tray will not shift or shake during rotation, guaranteeing that the scum can accurately enter the material-collecting filter frame 333. It also enhances the connection stability between the feeding assembly 33 and the filter assembly 31, making the entire device more reliable during operation. The outer end of the material-collecting filter frame 333 abuts against the inner force-guiding spring 316. The sliding material cylinder 332 is inclined, and the upper sliding material cylinder 331 is curved. The feeding tray is made of a rigid material. The material-holding filter frame 333 is equipped with multiple reinforcing ribs. The feeding tray is made of a hard material with high hardness and wear resistance, such as wear-resistant alloy, which can withstand the impact and friction of falling scum, is not easily worn, and extends the service life of the feeding tray. The reinforcing ribs on the material-holding filter frame 333 are reasonably distributed, which can enhance the structural strength of the filter frame and prevent it from deforming under the pressure of scum during the filtration process, ensuring the stability of the filtration effect. The sieve hole diameter on the filter screen outer frame 311 is smaller than the hole diameter on the filter screen support 314, and the sieve hole diameter on the filter screen support 314 is smaller than the hole diameter on the material-holding filter frame 333. This step-by-step filtration hole diameter design {filter screen outer frame 311 < filter screen support 314 < material-holding filter frame 333} forms a "coarse filtration - The graded filtration system of "medium-fine filtration" has a larger pore size in the material holding filter frame, which filters out larger scum particles first; the pore size of the filter screen support is next, filtering out medium-sized particles; and the pore size of the filter screen outer frame is the smallest, filtering out fine particles and impurities. This graded filtration method can ensure efficient separation of the decomposed liquid and solid particles, accurately separating particles of different sizes, thereby improving the purity of the liquid product and meeting production requirements. The filter screen outer frame 311, filter screen support 314, and material holding filter frame 333 are all cylindrical. The inner walls of the upper sliding long cylinder 331 and the lower sliding long cylinder 332 are inclined. The cylindrical structure of the filter screen outer frame 311, filter screen support 314, and material holding filter frame 333 can provide a larger filtration area and improve filtration efficiency. The inclined inner walls of the upper sliding long cylinder 331 and the lower sliding long cylinder 332 help the scum to slide smoothly under gravity, reducing the adhesion and accumulation of scum on the cylinder wall and ensuring smooth material flow.

[0052] This application also provides a method for treating copper slag removal from lead electrolytic anodes, comprising the following steps:

[0053] S1. Material Feeding: Open the sealing cover 23 and feed the copper removal slag from the lead electrolytic anode into the filter assembly 31 inside the shell 11 through the distribution component 22. The guide plate 223 and the feeding tray work together to ensure that the slag falls evenly. During the material feeding process, the operator should pay attention to controlling the feeding speed to avoid feeding too much slag at once, so as not to cause blockage of the distribution component 22. The sealing cover should be closed in time after feeding to ensure the airtightness of the device and maintain a stable environment inside the device. This not only prevents gas from escaping, but also prevents outside air from entering and affecting the decomposition reaction. The precise cooperation between the guide plate 223 and the feeding tray can evenly distribute the slag into each filter assembly 31, avoiding excessive accumulation of slag in a certain area, providing good conditions for subsequent decomposition processing, and ensuring that the slag in each area can fully contact the decomposition liquid, thereby improving the overall decomposition efficiency.

[0054] S2. Decomposition Processing: Start the drive motor 16 to drive the rotating shaft 17, the clamping bar 19, and the scum treatment mechanism 3 to rotate. Collect gas through the gas collection pipe 15. Decompose the scum in the decomposition liquid. The arc-shaped scraper 312 contacts the blocking bar 18 to generate vibration. The vibration force is transmitted to the filter screen support 314 and the material holding filter frame 333 through the outer force guiding spring 315 and the inner force guiding spring 316 to avoid clogging of the screen holes and to achieve scum vibration screening. The selection of the decomposition liquid should be adjusted according to the specific composition of the scum. For example, when the scum contains a lot of copper oxide, an acidic decomposition liquid, such as sulfuric acid solution, can be used to improve the rate and completeness of the decomposition reaction. After the drive motor 16 starts, it should maintain a stable speed to ensure that the rotating shaft drives the scum treatment mechanism to rotate smoothly, so that the scum and decomposition liquid can be fully mixed and reacted. The gas collected by the gas collection pipe 15 should be promptly transported to a special treatment equipment for purification treatment, and then discharged after meeting environmental emission standards. The collision frequency and vibration intensity of the arc scraper 312 and the baffle bar 18 should be moderate. It should ensure sufficient vibration force to prevent screen hole blockage and achieve scum screening, while avoiding excessive vibration force to prevent damage to the device components. Through this decomposition treatment method, metals such as copper in the scum can be fully dissolved into the decomposition liquid, preparing for subsequent separation and recovery.

[0055] S3. Filtration and Separation: The decomposed material is filtered step-by-step through the sieve holes of the feeding filter 333, the filter screen support 314, and the outer filter screen frame 311. Larger particles remain in the feeding filter 333, while smaller and finer particles enter the filter screen support 314 and are then filtered through the sieve holes. Fine particles enter the outer filter screen frame 311. The decomposed liquid enters the housing 11 through the sieve holes of the outer filter screen frame 311. During the filtration and separation process, close attention should be paid to the filtration speed and the clogging of the sieve holes. If clogging is detected... A significant slowdown in filtration speed may indicate slight blockage of the sieve openings. In this case, the device's own vibrating sieve mechanism will kick in, dislodging the blocked particles through vibration and restoring the filtration speed. If the filtration speed remains too slow, it may be necessary to stop the machine for inspection and cleaning of impurities from the sieve openings. The step-by-step filtration method ensures that particles of different sizes are effectively separated, greatly reducing the content of solid impurities in the liquid product and improving the purity of the liquid product. This provides high-quality raw materials for subsequent metal recovery. At the same time, the separated solid particles of different sizes can be further processed and utilized as needed, maximizing resource utilization.

[0056] S4. Product Collection: Stop the motor, open the bottom outlet of the housing 11 to collect the liquid, press the rotating arm 173, remove the scum treatment mechanism 3 and collect the internal particles. When collecting the product, the operator should pay attention to safety, wear necessary protective equipment, and avoid contact with the decomposition liquid and scum particles. When opening the bottom outlet of the housing, it should be opened slowly to control the flow rate of the liquid and prevent liquid splashing. When pressing the rotating arm 173, force should be applied evenly to separate the rotating arm 173 from the positioning ring 330, and then the scum treatment mechanism 3 should be removed smoothly to avoid collision and damage to the device parts. The collected liquid and particles should be stored separately in dedicated containers. The liquid can be used for subsequent metal extraction processes, while the particles can be further processed or recycled according to their composition and particle size. This convenient collection method reduces the complexity and labor intensity of manual operation, improves production efficiency, and also ensures the accuracy and integrity of product collection.
