Description

Technical Field

[0001] The invention relates to the technical field of lead electrolysis anode copper scum removal treatment, and in particular to a lead electrolysis anode copper scum removal treatment device and method. Background Art

[0002] During the production of lead electrolytic anodes, scum containing metals such as copper is produced. If not properly treated, this scum not only wastes resources but also pollutes the environment. Currently, there are several technical challenges in the field of removing copper scum from lead electrolytic anodes that need to be addressed.

[0003] Existing lead electrolysis anode copper scum treatment devices and methods often suffer from insufficient scum decomposition during scum treatment. This is because the scum, after being introduced into the treatment device, cannot evenly contact the decomposition solution, resulting in low decomposition efficiency and affecting subsequent treatment results.

[0004] Another significant issue is poor filtration and separation. The existing filter structure is not designed properly, and during the filtration process, the screen holes are easily clogged by scum particles, resulting in slow filtration and even requiring frequent cleaning stops, which seriously affects the continuity of the process and production efficiency.

[0005] At the same time, existing devices lack an effective vibration screening mechanism when processing scum, which causes scum particles to accumulate during the filtration process, making it impossible to achieve sufficient graded filtration, resulting in low purity of the final collected product and making it difficult to meet production needs.

[0006] Furthermore, existing treatment methods suffer from uneven material distribution during material placement and distribution, which can lead to over-treatment of slag in some areas and incomplete treatment in others, further impacting overall treatment quality and efficiency.

DETAILED DESCRIPTION

[0027] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0028] This embodiment provides a technical solution: a device and method for removing copper scum from lead electrolysis anodes, such as Figure 1-12 As shown, it includes a cylindrical shell 11, a pair of annular grooves 14 are fixedly sleeved on the outer wall of which a plurality of evenly distributed exhaust holes 12 are opened in the annular grooves 14, and a material blocking net 13 is installed in the exhaust holes 12; the pair of annular grooves 14 are connected by an air collection pipe 15, and the air collection pipe 15 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 scum removal process of the lead electrolysis anode. The cooperation between the annular grooves 14 and the exhaust holes 12 can collect these gases in time and transport them to subsequent purification treatment devices through the air collection pipe 15 to avoid harmful gases being directly discharged into the environment to cause pollution. The material blocking net 13 is made of corrosion-resistant metal material, which can effectively block scum particles from entering the exhaust holes. At the same time, its corrosion-resistant properties can ensure that it can still work normally under long-term contact with corrosive gases and liquids, thereby extending the service life of the device.

[0029] A driving motor 16 is fixed to the bottom of the shell 11 by a mounting bracket, and a rotating shaft 17 is provided in the shell 11 above the motor. A card strip 19 distributed in a circumferential array is provided on the outer wall of the rotating shaft 17, and a blocking strip 18 distributed in a circumferential array is fixed to the inner wall of the shell. The card strip 19 is driven to rotate by the rotating shaft 17. When the card strip 19 collides with the blocking strip 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 the scum and the decomposition liquid, so that the scum particles can more comprehensively contact the decomposition liquid, thereby improving the decomposition efficiency; on the other hand, the vibration acts on the filter assembly 31 to prevent the sieve holes from being blocked by scum particles, ensuring the smooth progress of the filtration process and avoiding the problems of reduced processing efficiency and frequent shutdowns for cleaning due to sieve hole blockage.

[0030] The slag distributing mechanism 2 is installed on the top of the main structure 1, and includes a cover plate 21, the top center of which is connected to the distributing component 22 through a through hole, and a sealing cover 23 is provided above the distributing component 22; the cover plate 21 plays the role of supporting and fixing the distributing component 22, and the sealing cover 23 adopts a structural design with good sealing performance. It opens when the material is added and closes after the addition is completed. It can not only prevent gas from escaping during the addition process and maintain the sealed environment inside the device, but also prevent external debris from entering the interior of the device and affecting the slag treatment effect.

[0031] The scum treatment mechanism 3 is installed inside the main structure 1 and includes a support tube 32 fixed on the rotating shaft 17, on which are provided a circumferential array of filter components 31. A discharge component 33 is commonly provided inside the multiple filter components 31. The filter components 31 and the discharge component 33 cooperate to achieve the decomposition and step-by-step filtration of the scum. The support tube 32 and the rotating shaft 17 drive the rotation to ensure that the scum is in full contact with the decomposition liquid.

[0032] The rotating shaft 17 includes a shaft body 171, the lower end of which passes through the bottom of the shell 11 and is fixedly connected to the coupling on the output shaft of the drive motor 16, and is rotatably connected to the shell 11; the outer wall of the top end of the shaft body 171 is provided with a plurality of groove bodies 172 distributed in a circumferential array, in which a rotating arm 173 is rotatably connected through a rotating rod, and a wavy spring piece 174 is fixedly connected between the rotating arm 173 and the inner wall of the groove body 172; during the rotation process, the rotating arm 173 can elastically abut the blanking component 33 under the action of centrifugal force and elastic force, so as to The discharge assembly 33 provides dynamic pressure, which can assist in stabilizing the decomposition process of the scum. The clamping strip 19 is fixedly connected to the outer wall of the shaft 171. The shaft 171 is fixedly sleeved with a fixed sleeve located in the shell 11. The fixed sleeve is made of high-strength metal material and fits tightly with the shaft to ensure that the support tube 32 is stably installed and will not shake or deviate during rotation, thereby ensuring the normal operation of the filter assembly 31 and the discharge assembly 33 and avoiding affecting the scum treatment effect due to unstable installation.

[0033] like Figure 3 、 Figure 4 and Figure 12 As shown, the material distribution component 22 includes a funnel body 221 fixedly connected to the central through hole of the cover plate 21, and a plurality of discharge holes 222 distributed in a circumferential array are opened at the bottom end of the inner portion thereof, and a material guide inclined plate 223 fixedly connected to the bottom of the funnel body 221 and having a concave top and a convex bottom is provided at the lower end port of the hole, and a plurality of first convex strips are fixedly connected to the concave surface of the material guide inclined plate 223, and the inner edge of the funnel body 221 and the adjacent discharge holes 222 are all sloped, and the height decreases from the edge to the center, and the center is convex at the top and concave at the bottom; the edge of the discharge hole 222 is chamfered, and the sealing cover 23 is installed in the funnel body 221, and the inner edge of the funnel body 221 and the adjacent discharge holes are all sloped, and the height decreases from the edge to the center, and the center is convex at the top and concave at the bottom. This unique sloped structure The structural design allows the scum to slide naturally along the slope under the action of gravity. Since the height of the slope is evenly distributed, the scum will gather evenly toward the center. The concave top and convex bottom shape of the guide inclined plate 223 cooperates with the sloped funnel body 221 to further guide the flow direction of the scum, and the multiple first convex strips in the concave surface can effectively break up the accumulated scum clumps, avoid scum agglomeration, and ensure that the scum can evenly pass through each discharge hole 222 and fall into the processing mechanism 3 below, thereby achieving uniform delivery of the scum and laying a good foundation for subsequent sufficient decomposition. The chamfered design of the edge of the discharge hole 222 can reduce the friction resistance between the material and the edge of the hole, so that the scum can pass through the discharge hole more smoothly, avoid the occurrence of material jamming, and further ensure the uniformity and continuity of material distribution.

[0034] like Figures 4 to 11 As shown, the filter assembly 31 includes a filter outer frame 311 fixedly connected to the outer wall of the support tube 32, a filter bracket 314 is fixedly connected to the inside thereof, an arc-shaped scraper 312 fixedly connected to the outer end of the filter outer frame 311 and fitted with the inner wall of the shell 11, a weakening groove 313 is provided on the scraper, and the outer wall and inner wall of the outer end of the filter bracket 314 are fixedly connected with a curved outer guide spring piece 315 and an inner guide spring piece 316 respectively; when the arc-shaped scraper 312 rotates with the support tube 32, it collides with the blocking bar 18 on the inner wall of the shell 11. The weakening groove 313 weakens the structure at the groove 313 more easily during collision, thereby enhancing the vibration effect. The vibration force is transmitted to the filter bracket 314 and the filter frame 333 through the outer guide spring piece 315 and the inner guide spring piece 316. This elastic transmission method can make the vibration evenly distributed on the filter component 31, effectively preventing the screen holes from being blocked by scum particles. When the scum particles contact the screen, the vibration will prevent the particles from staying and accumulating on the screen, but will fall through the screen holes in time, keeping the screen holes unobstructed and ensuring the continuous filtration process.

[0035] Adjacent filter outer frames 311 are staggered to form triangular holes, and a mounting groove is provided at the top of the side wall connected to the support tube 32. The filter outer frame 311 and the arc scraper 312 are both curved. The support tube 32 is sleeved on the shaft 171, and its bottom is fitted with the fixed sleeve and installed between the fixed sleeve and the rotating arm 173. The outer wall of the support tube 32 is provided with a card slot that is clamped on the card strip 19; the outer walls of the filter outer frame 311 and the filter bracket 314 are both provided with reinforcing ribs, and the reinforcing ribs are made of the same high-strength material as the filter outer frame 311 and the filter bracket 314. Through reasonable layout design, the structural strength of the filter assembly 31 can be significantly improved, so that it will not be deformed or damaged when subjected to long-term vibration and scum pressure, thereby ensuring the stability and reliability of the filter assembly and extending the service life of the device.

[0036] The material discharge assembly 33 includes an upper sliding material cylinder 331 located below the guide inclined plate 223, the lower end of which is fixedly connected to a lower material cylinder 332 and a material filter frame 333 in sequence, the material filter frame 333 is located in the filter screen bracket 314, and a connecting baffle 334 is fixedly connected between adjacent upper sliding material cylinders 331. The upper sliding material cylinder 331 and the connecting baffle 334 form a material discharge tray that fits the inner wall of the shell 11. The lower sliding material cylinder 332 is inclined and the upper sliding material cylinder 331 is curved. This special shape design is based on According to the principles of fluid mechanics, the inclined downward sliding cylinder 332 can guide the scum to slide smoothly under the action of gravity, while the curved upward sliding cylinder 331 can adjust the falling direction of the scum so that the scum can fall evenly into the material holding filter frame 333. The discharge tray fits tightly against the inner wall of the shell 11, and a high-precision processing technology is used to ensure the fit. This can effectively prevent the scum from falling from the gap between the discharge tray and the shell, avoiding material waste, and at the same time ensure that all the scum enters the material holding filter frame 333 for processing, thereby improving processing efficiency.

[0037] The top of the locating ring 330 abuts against the bottom of the rotating arm 173, and the bottom of the locating ring 330 abuts against the bottom of the rotating arm 173. The guide post 336 is fixedly connected to the material guide post 336 inserted into the triangular hole. The material guide post 336 is inserted into the triangular hole, which can play a good positioning and stabilizing role, ensuring that the material tray will not be displaced or shaken during the rotation, and ensuring that the slag can accurately enter the material filter holder 333. At the same time, it also enhances the connection stability between the material filter holder 333 and the filter holder 31, making the entire device more reliable during operation. The outer end of the material filter holder 333 abuts against the inner guide spring piece 316, and the lower material cylinder 332 is inclined, and the upper material cylinder 331 is curved. The disc is made of hard material, and a plurality of reinforcing ribs are provided on the filter frame 333. The discharge disc is made of hard material with high hardness and strong wear resistance, such as wear-resistant alloy, which can withstand the impact and friction when the scum falls, is not easy to wear, and prolongs the service life of the discharge disc. The reinforcing ribs on the filter frame 333 are reasonably distributed, which can enhance the structural strength of the filter frame, so that it will not be deformed due to the pressure of the scum during the filtration process, thereby ensuring the stability of the filtration effect. The aperture of the sieve material on 311 is smaller than that of 314, and the aperture of the sieve material on 314 is smaller than that of 333. The step-by-step filtration aperture design {filter outer frame 311 < filter bracket 314 < discharge assembly 33} This step-by-step increasing sieve material aperture design forms a "coarse filtration- The filter holder 314 has a cylindrical shape, and the inner walls of the upper sliding cylinder 331 and the lower sliding cylinder 332 are inclined. The cylindrical structures of the filter holder 311, the filter holder 314 and the filter holder 333 can provide a large filtration area and improve filtration efficiency. The inclined inner walls of the upper sliding cylinder 331 and the lower sliding cylinder 332 help the scum to slide down smoothly under the action of gravity, reduce the adhesion and accumulation of scum on the cylinder wall, and ensure smooth discharge of materials.

[0038] The present application also provides a method for treating a lead electrolysis anode copper scum removal device, comprising the following steps: S1. Material feeding: Open the sealing cover 23, and feed the copper removal scum from the lead electrolysis anode into the filter cartridge 31 in the housing 11 through the material distribution assembly 22. The guide ramp 223 cooperates with the discharge tray to make the scum fall evenly. During the material feeding process, the operator should pay attention to controlling the feeding speed to avoid feeding too much scum at one time to avoid clogging the material distribution assembly 22. The sealing cover should be closed in time after the feeding is completed to ensure the sealing 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 ramp 223 and the discharge tray can evenly distribute the scum to each filter cartridge 31, avoiding excessive accumulation of scum in a certain area, providing good conditions for subsequent decomposition treatment, so that the scum in each area can fully contact the decomposition liquid, and improve the overall decomposition efficiency.

[0039] S2. Decomposition: The drive motor 16 is started to rotate the rotating shaft 17, the clamping bar 19, and the scum processing mechanism 3. Gas is collected through the air collection pipe 15. The scum is decomposed in the decomposition liquid. The arc-shaped scraper 312 contacts the blocking bar 18 and vibrates. The vibration force is transmitted to the filter bracket 314 and the material filter holder 333 through the outer guide spring piece 315 and the inner guide spring piece 316, thereby preventing the sieve holes from being blocked and achieving scum vibration screening. The choice of decomposition liquid should be adjusted according to the specific composition of the scum. For example, when the scum contains a large amount of copper oxide, an acidic decomposition liquid, such as sulfuric acid solution, can be used to increase the rate and completeness of the decomposition reaction. After the drive motor 16 is started, it should maintain a stable speed to ensure that the rotating shaft drives the slag processing mechanism to rotate smoothly, so that the slag and the decomposition liquid can be fully mixed and reacted. The gas collected by the air collection pipe 15 should be promptly transported to a special processing equipment for purification and discharged after meeting environmental emission standards. The collision frequency and vibration intensity of the curved scraper 312 and the blocking bar 18 should be moderate, ensuring sufficient vibration force to prevent sieve hole blockage and achieve slag vibration, while avoiding excessive vibration force that may cause damage to the device components. Through this decomposition treatment method, metals such as copper in the slag can be fully dissolved in the decomposition liquid, preparing for subsequent separation and recovery.

[0040] S3, filtration separation: the decomposed material is filtered step by step through the sieve holes of the material holding filter frame 333, the filter bracket 314 and the filter outer frame 311. The decomposed material is filtered through the sieve holes of the material holding filter frame 333. Larger particles will remain in the material holding filter frame 333, smaller particles and fine particles will enter the filter bracket 314, and then filtered by the sieve holes of the filter bracket 314. Fine particles enter the filter outer frame 311, and the decomposed liquid will enter the housing 11 through the sieve holes of the filter outer frame 311. During the filtration separation process, close attention should be paid to the filtration speed and the blockage of the sieve holes. If it is found that the filter is too large, the filter will be blocked. The filtration speed slows down significantly, which may be due to a slight blockage in the sieve holes. At this time, the device's own vibration mechanism will come into play, causing the blocked particles to fall off through vibration and restore the filtration speed. If the filtration speed continues to be too slow, it may be necessary to stop the machine for inspection and clean the impurities in the sieve holes. The step-by-step filtration method can ensure that particles of different particle sizes are effectively separated, and the solid impurity content in the liquid product is greatly reduced, thereby improving the purity of the liquid product and providing high-quality raw materials for subsequent metal recovery. At the same time, the separated solid particles of different particle sizes can also be further processed and utilized as needed to maximize resource utilization.

[0041] S4. Product collection: Stop the motor, open the bottom discharge port of the shell 11 to collect the liquid, press the rotating arm 173, remove the scum processing 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 discharge port of the shell, it should be opened slowly to control the outflow rate of the liquid to prevent liquid splashing. When pressing the rotating arm 173, apply force evenly to separate the rotating arm 173 from the positioning ring 330, and then smoothly remove the scum processing mechanism 3 to avoid collision and damage to the device components. The collected liquid and particles should be stored in dedicated containers respectively. The liquid can be used in the subsequent metal extraction process, and 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 completeness of product collection.
