Description

Technical Field

[0001] This invention relates to the field of gravure printing roller processing, and in particular to an automated polishing copper grinding water circulation system and method for printing rollers. Background Technology

[0002] Polishing is a crucial step in the manufacturing of printing rollers, used to improve the smoothness and precision of the roller surface. Traditional polishing processes typically generate large amounts of copper-grinding wastewater, which contains copper particles, abrasives, and other impurities. With increasingly stringent environmental regulations, how to efficiently treat this wastewater has become an important issue in the industry. Currently, the industry mainly treats copper-grinding wastewater through physical sedimentation, chemical treatment, and filtration. However, these methods suffer from low treatment efficiency, high costs, and secondary pollution. Furthermore, with the development of automation technology, more and more companies are introducing automated polishing equipment, but the demand for supporting wastewater treatment systems is also becoming increasingly urgent.

[0003] However, the existing methods for treating copper grinding water often have the following problems: copper grinding water contains a certain amount of metal particles, which are quite hard and easily clog the screen. Directly processing the copper grinding water by separating it with a centrifuge can easily cause wear and tear on the internal parts of the machine.

[0004] Therefore, there is an urgent need for an automated copper polishing water circulation system and method for printing rollers. Summary of the Invention

[0013] On the other hand, this application also provides an automated polishing copper grinding water circulation treatment method for printing rollers, the specific steps of which are as follows: S1. Introducing copper grinding water: The user introduces copper grinding water into the dispersion box using the copper grinding water introductory tube, activates the first motor to rotate the first shaft, and uses the dispersion plate to evenly disperse the copper grinding water and internal impurity particles, and pours it into the magnetic suction box through the first and second diversion tubes respectively. S2. Magnetic particle separation: The user uses the second motor to rotate the magnetic suction rod to magnetically attract the copper grinding water flowing out from the first and second diversion pipes. At the same time, a magnetic grid is used for secondary attraction. The attracted copper grinding water flows into the first fluid pipe according to gravity. S3. Impurity Flocculation and Screening: The adsorbed copper grinding water flows into the filter box from the first fluid pipe. Flocculant is slowly added to the adsorbed copper grinding water through the seepage block under the feed hopper to promote the flocculation and precipitation of copper ions. The adsorbed and flocculated copper grinding water is triple-screened using a coarse screen, a fine screen, and a carbon filter. At this time, the third motor is activated to rotate the transmission wheel, which drives the third rotating shaft to rotate the guide plate. This allows the copper grinding water that has just been added with flocculant to be mixed with other copper grinding water through the guide plate. The displacement of the push-pull rod by the cylinder continuously changes the addition point of the flocculant. At the same time, the top of the coarse screen is cleaned by a scraper to avoid blockage. The upward flow of liquid from the guide plate cleans the area of ​​the coarse screen at the bottom of the third rotating shaft, floating the impurities on the top of the coarse screen and throwing them to the periphery by centrifugal force. The impurities are then collected and cleaned to the left and right sides of the filter box by the scraper. S4. Returning filtered water: The filtered copper polishing water flows out in a concentrated manner through the second fluid pipe and the guide and limit plate. It is then purified through multiple processes, including centrifugal separation and activated carbon filter. The treated clean water is sent back to the polishing equipment for recycling.

[0014] In summary, the present invention provides an automated copper polishing water circulation system and method for printing rollers, which has the following beneficial effects: 1. This automated polishing copper polishing water circulation system and method for printing rollers involves introducing copper polishing water through a copper polishing water inlet pipe, followed by dispersion through a dispersion unit. A first rotating shaft drives a dispersion plate to agitate the copper polishing water and disperse internal impurities, preventing blockages caused by impurity accumulation during transport. Simultaneously, even when the dispersion box is not completely filled with liquid, or the flow rate of the copper polishing water inlet pipe is low, the flow is evenly divided into three streams for convenient transport and subsequent work. A distribution plate holds the newly introduced copper polishing water above it, ensuring that the dispersed water falls below its outer surface after being dispersed by the dispersion plate, preventing it from returning to the distribution plate's area. This ensures that even when the flow rate is insufficient... In this case, the efficiency and stability of the uniform dispersion can be further accelerated. The copper grinding water then enters the magnetic adsorption unit, where the metal particles in the copper grinding water are adsorbed by the magnetic adsorption rod. The falling copper grinding water is adsorbed again by the magnetic grid. At the same time, the metal particles in the copper grinding water that were previously dispersed can remain evenly on the magnetic adsorption rod and the magnetic grid, which can avoid the accumulation of metal particles in the same place when they are not dispersed, which would make it difficult to clean later. When metal particles accumulate, the metal particles at the bottom will gradually increase with adsorption and sedimentation, causing the water level of the copper grinding water that flows in later to rise higher and higher. The water level is detected by the liquid level detector and the alarm is triggered in time to prevent the copper grinding water from overflowing.

[0015] 2. The automated copper polishing water circulation system and method for this roller polishing system involves the copper polishing water entering the stirring unit. Power from the third motor is transmitted to multiple drive wheels via a transmission belt. The incoming copper polishing water is guided by guide vanes on the surface of the third rotating shaft, causing the liquid in the center to surge upwards. During this process, centrifugal force generated by rotation disperses the copper polishing water outwards, making the composition of the copper polishing water more uniform and providing favorable conditions for subsequent filtration. Then, auxiliary materials required for filtration, including flocculants, are added through a permeate block. During this process, the flocculants are quickly and evenly dispersed into the copper polishing water by the rotation of the guide vanes, improving the filtration effect and preventing the flocculants from being repeatedly added to the same area, which would hinder their rapid effectiveness on the copper polishing water in other areas.

[0016] 3. The automated copper polishing water circulation system and method for this printing roller involves filtering the copper polishing water through a triple filtration process while it is flocculating. The scraper, driven by the push-pull rod, scrapes the surface of the coarse screen to prevent clogging. Simultaneously, during the movement of the guide vanes, impurities trapped or blocked in the top area of ​​the coarse screen, located at the bottom of the third rotating shaft, are thrown out by the water flow and pushed to the left and right sides of the filter box by the reciprocating motion of the scraper. Impurities at this location are furthest from the guide vanes and experience relatively less traction, allowing them to gradually accumulate in the same spot for easy cleaning by staff, preventing clogging, reduced filtration efficiency, and decreased flow rate.

[0019] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the present invention provides a technical solution: an automated polishing copper grinding water circulation system for printing rollers, including a copper grinding water inlet pipe 1, a filter mechanism 2 is provided on the right side of the copper grinding water inlet pipe 1, and the left side of the filter mechanism 2 is adapted to the right side of the copper grinding water inlet pipe 1. The filtration mechanism 2 includes a dispersion unit 21, a magnetic suction unit 22 is provided on the right side of the dispersion unit 21, and the left side of the dispersion unit 21 is adapted to the right side of the copper grinding water inlet pipe 1. The magnetic suction unit 22 is used in conjunction with the dispersion unit 21. The filtration mechanism 2 also includes a stirring unit 23, and a filtration unit 24 is provided inside the stirring unit 23. The left side of the stirring unit 23 is adapted to the right side of the magnetic suction unit 22, and the filtration unit 24 is used in conjunction with the stirring unit 23.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the dispersion unit 21 includes a dispersion box 2101. The right side of the copper grinding water inlet pipe 1 is fixedly connected to the left side of the dispersion box 2101. A first motor 2102 is fixedly connected to the top of the dispersion box 2101. A first rotating shaft 2103 is fixedly connected to the bottom of the first motor 2102. Multiple dispersion plates 2104 are fixedly connected to the outer surface of the first rotating shaft 2103. The multiple dispersion plates 2104 are arranged in a circular array around the first rotating shaft 2103. A first diversion pipe 21 is fixedly connected to the right side of the dispersion box 2101. 06. The front and rear sides of the dispersion box 2101 are respectively fixedly connected with the second diversion pipe 2107. The copper grinding water is contained in the dispersion box 2101, and the copper grinding water and internal impurities are dispersed by the stirring of the dispersion plate 2104 driven by the first rotating shaft 2103. This can prevent the blockage caused by the accumulation of impurities in the copper grinding water during transportation. At the same time, when the dispersion box 2101 is not full of liquid and the flow rate of the copper grinding water inlet pipe 1 is not large, the flow rate can be evenly divided into three streams, which is convenient for transportation and subsequent work.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a diversion plate 2105 is fixedly connected to the bottom of the inner wall of the dispersion box 2101. The top of the diversion plate 2105 is attached to the bottom of the copper grinding water inlet pipe 1. The outer surface of the diversion plate 2105 is adapted to the first diversion pipe 2106 and the second diversion pipe 2107 respectively. The diversion plate 2105 holds the copper grinding water that has just been introduced above it, so that after the dispersion plate 2104 disperses it, it falls under the outer surface of the diversion plate 2105 and will not return to the range of the diversion plate 2105. When the flow rate is not sufficient, it can further accelerate the efficiency and stability of uniform dispersion.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the magnetic suction unit 22 includes a magnetic suction box 2201. The left side of the magnetic suction box 2201 is fixedly connected to the right side of the first diversion pipe 2106 and the second diversion pipe 2107, respectively. A second motor 2202 is fixedly connected to the front of the magnetic suction box 2201, and a magnetic suction rod 2203 is fixedly connected to the back of the second motor 2202. A magnetic grid 2206 is fixedly connected to the bottom of the inner wall of the magnetic suction box 2201. A first fluid pipe 2209 is fixedly connected to the right side of the magnetic suction box 2201, and multiple support columns 2210 are fixedly connected to the bottom of the magnetic suction box 2201. The magnetic suction rod 2203 adsorbs the metal particles in the copper grinding water. The falling copper grinding water is adsorbed again by the magnetic grid 2206. At the same time, the metal particles in the copper grinding water that were previously dispersed can be evenly left on the magnetic suction rod 2203 and the magnetic grid 2206, which can prevent the metal particles from accumulating in the same place when the water is not diverted, making it difficult to clean later.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a bearing 2205 is fixedly connected to the front of the inner wall of the magnetic suction box 2201. A second rotating shaft 2204 is rotatably connected inside the bearing 2205. The front of the second rotating shaft 2204 is fixedly connected to the back of the magnetic suction rod 2203. A liquid level detector 2207 is fixedly connected to the inside of the right side of the magnetic suction box 2201. An alarm 2208 is fixedly connected to the top of the liquid level detector 2207. The alarm 2208 is electrically connected to the liquid level detector 2207. When metal particles accumulate, the metal particles at the bottom will gradually increase with adsorption and sedimentation, causing the level of the copper grinding water that flows in later to rise higher and higher. The liquid level detector 2207 detects the water level and the alarm 2208 promptly sounds an alarm to prevent the copper grinding water from overflowing.

[0025] like Figure 1 , Figure 4 and Figure 5As shown, the stirring unit 23 includes a filter box 2301. The left side of the filter box 2301 is fixedly connected to the right side of the first fluid pipe 2209. A mounting plate 2302 is fixedly connected to the top of the filter box 2301. A support plate 2303 is fixedly connected to the top of the mounting plate 2302. A third motor 2304 is fixedly connected to the top of the support plate 2303. A transmission wheel 2305 is fixedly connected to the bottom of the third motor 2304. Multiple transmission wheels 2305 are provided, and the surfaces of multiple transmission wheels 2305 are all meshed with the same transmission belt 2306. Limiting rings 2307 are fixedly connected to the bottom of multiple transmission wheels 2305. The bottom of each of the 307 is attached to the top of the same mounting plate 2302. The bottom of each of the multiple limiting rings 2307 is fixedly connected to a third rotating shaft 2308. The outer surface of each of the multiple third rotating shafts 2308 is fixedly connected to a guide plate 2309. The power of the third motor 2304 is transmitted to multiple transmission wheels 2305 through the transmission belt 2306. The guide plate 2309 on the surface of the third rotating shaft 2308 guides the incoming copper grinding water, causing the liquid in the center to surge upward. During this process, the centrifugal force generated by the rotation rotates the copper grinding water to the outside, making the composition of the copper grinding water more uniform and providing favorable conditions for subsequent filtration operations.

[0026] like Figure 1 , Figure 4 and Figure 6 As shown, the filter unit 24 includes a cylinder 2401. The left side of the cylinder 2401 is fixedly connected to the right side of the filter box 2301. A push-pull rod 2402 is fixedly connected to the left side of the cylinder 2401. A seepage block 2404 is provided on the top of the push-pull rod 2402. A feed hopper 2405 is fixedly connected to the top of the seepage block 2404. The outer side of the seepage block 2404 is adapted to the guide plate 2309. The auxiliary materials required for filtration, including flocculant, are added through the seepage block 2404. In this process, the flocculant can be quickly and evenly dispersed into the copper grinding water by the rotation of the guide plate 2309, thereby improving the filtration effect.

[0027] like Figure 1 , Figure 4 and Figure 6As shown, a scraper 2403 is fixedly connected to the left side of the push-pull rod 2402. The left side of the scraper 2403 is fixedly connected to the right side of the seepage block 2404. A coarse screen 2406 is fixedly connected to the inner wall of the filter box 2301. The top of the coarse screen 2406 is in contact with the bottom of the scraper 2403. A fine screen 2407 is provided at the bottom of the coarse screen 2406. A carbon filter 2408 is provided at the bottom of the fine screen 2407. An inclined plate 2409 is provided at the bottom of the carbon filter 2408. The bottom of the inclined plate 2409 is fixedly connected to the top of the filter box 2301. A second fluid pipe 2410 is provided on the right side of the inclined plate 2409. The right side of the second fluid pipe 2410 penetrates the inner wall of the filter box 2301 and extends to the right side of the filter box 2301. A limiting frame 2411 is fixedly connected to the right side of the filter box 2301. The limiting frame 2411 is adapted to the second fluid pipe 2410. The scraper 2403 scrapes the surface of the coarse screen 2406 under the movement of the push-pull rod 2402 to prevent impurities from clogging. The copper grinding water is filtered through triple filtration. At the same time, during the movement of the guide plate 2309, the impurities that are retained or blocked in the bottom area of ​​the third rotating shaft 2308 and the top area of ​​the coarse screen 2406 can be thrown out by the water flow and pushed to the left and right sides of the filter box 2301 by the reciprocating motion of the scraper 2403. The impurities at this position are farthest from the guide plate 2309 and are subject to relatively less traction force. They can gradually accumulate in the same position, making it convenient for staff to clean them up. Example

[0028] like Figure 7 As shown, the present invention provides another technical solution, a method for automated polishing of printing rollers using copper grinding water circulation, the specific steps of which are as follows: S1. Introducing copper grinding water: The user introduces copper grinding water into the dispersion box 2101 through the copper grinding water inlet pipe 1, activates the first motor 2102 to rotate the first rotating shaft 2103, and uses the dispersion plate 2104 to evenly disperse the copper grinding water and internal impurity particles, and pours it into the magnetic suction box 2201 through the first diversion pipe 2106 and the second diversion pipe 2107 respectively. S2, Magnetic Particle Separation: The user uses the second motor 2202 to rotate the magnetic suction rod 2203 to magnetically attract the copper grinding water flowing out from the first diversion pipe 2106 and the second diversion pipe 2107. At the same time, the magnetic grid 2206 performs secondary attraction. The attracted copper grinding water flows into the first fluid pipe 2209 according to gravity. S3. Impurity Flocculation and Screening: The adsorbed copper-grinding water flows into the filter box 2301 from the first fluid pipe 2209. Flocculant is slowly added to the adsorbed copper-grinding water through the seepage block 2404 under the feed hopper 2405 to promote copper ion flocculation and precipitation. The adsorbed and flocculated copper-grinding water is triple-screened using a coarse screen 2406, a fine screen 2407, and a carbon filter 2408. At this time, the third motor 2304 is activated to rotate the transmission wheel 2305, which drives the third rotating shaft 2308 to rotate the guide vane 2309, allowing the newly added flocculated... The copper-based liquid is stirred evenly in the other copper-based liquid by the guide plate 2309, and the disposition of the push-pull rod 2402 by the cylinder 2401 continuously changes the dosing point of the flocculant. At the same time, the scraper 2403 cleans the top of the coarse screen 2406 to prevent blockage. The upward flow of liquid from the guide plate 2309 cleans the area of ​​the coarse screen 2406 at the bottom of the third rotating shaft 2308, floats the impurities on the top of the coarse screen 2406 and throws them to the periphery according to the centrifugal force, and is then concentrated and cleaned to the left and right sides of the filter box 2301 by the scraper 2403. S4. Return of filtered water: The filtered copper polishing water flows out in a concentrated manner through the second fluid pipe 2410 and the inclined plate 2409. It is then purified through multiple processes of centrifugal separation and activated carbon filter. The treated clean water is sent back to the polishing equipment for recycling.

[0029] In use, copper grinding water is introduced through the copper grinding water inlet pipe 1 and then dispersed by the dispersion unit 21. The first rotating shaft 2103 drives the dispersion plate 2104 to agitate the copper grinding water and disperse internal impurities, preventing blockages caused by impurities accumulating during transportation. Simultaneously, even when the dispersion box 2101 is not completely filled with liquid and the flow rate of the copper grinding water inlet pipe 1 is low, the flow is evenly divided into three streams, facilitating transportation and subsequent work. The diversion plate 2105 holds the newly introduced copper grinding water above it, ensuring that the dispersed water falls below its outer surface after being dispersed by the dispersion plate 2104, preventing it from returning to the diversion plate 2105's area. In cases of insufficient flow, the efficiency and stability of uniform dispersion can be further accelerated. The copper grinding water then enters the magnetic adsorption unit 22, where the metal particles in the copper grinding water are adsorbed by the magnetic adsorption rod 2203. The falling copper grinding water undergoes secondary adsorption through the magnetic grid 2206. Simultaneously, the metal particles in the previously dispersed copper grinding water can remain evenly on the magnetic adsorption rod 2203 and the magnetic grid 2206, preventing the accumulation of metal particles in one place when not diverted, which would make subsequent cleaning difficult. When metal particles accumulate, the metal particles at the bottom will gradually increase with adsorption and sedimentation, causing the water level of the subsequently flowing copper grinding water to rise higher and higher. The water level is detected by the level detector 2207 and then... Alarm 2208 promptly alerts and prevents copper-grinding water from overflowing. The copper-grinding water then enters the stirring unit 23, where the power of the third motor 2304 is transmitted to multiple drive wheels 2305 via the transmission belt 2306. The guide vanes 2309 on the surface of the third rotating shaft 2308 guide the incoming copper-grinding water, causing the liquid in the center to surge upwards. During this process, the centrifugal force generated by the rotation disperses the copper-grinding water outwards, making the composition of the copper-grinding water more uniform and providing favorable conditions for subsequent filtration. Then, auxiliary materials required for filtration, including flocculant, are added through the permeate block 2404. During this process, the flocculant itself is rapidly and uniformly dispersed by the rotation of the guide vanes 2309. The filtration effect is improved by dispersing the copper grinding water. While the copper grinding water is flocculating, it is also filtered through triple filtration. The scraper 2403 scrapes the surface of the coarse screen 2406 under the movement of the push-pull rod 2402 to prevent impurities from clogging. At the same time, during the movement of the guide plate 2309, the impurities that are trapped or blocked in the top area of ​​the coarse screen 2406, located at the bottom area of ​​the third rotating shaft 2308, can be thrown out by the water flow and pushed to the left and right sides of the filter box 2301 by the reciprocating motion of the scraper 2403. The impurities at this position are farthest from the guide plate 2309 and are subject to relatively less traction force, so they can gradually accumulate in the same position, making it easier for staff to clean them up.

9. A method for automated copper polishing and water recycling of printing rollers, applicable to the automated copper polishing and water recycling system for printing rollers as described in any one of claims 1-8, characterized in that: The specific steps are as follows: S1. Introducing copper grinding water: The user introduces copper grinding water into the dispersion box (2101) using the copper grinding water inlet tube (1), activates the first motor (2102) to rotate the first shaft (2103), and uses the dispersion plate (2104) to evenly disperse the copper grinding water and internal impurity particles, and pours it into the magnetic suction box (2201) through the first diversion tube (2106) and the second diversion tube (2107) respectively. S2, Magnetic Particle Separation: The user uses the second motor (2202) to rotate the magnetic suction rod (2203) to magnetically attract the copper grinding water flowing out from the first diversion pipe (2106) and the second diversion pipe (2107). At the same time, a magnetic grid (2206) is used for secondary attraction. The attracted copper grinding water flows into the first fluid pipe (2209) according to gravity. S3. Impurity Flocculation and Screening: The adsorbed copper grinding water flows into the filter box (2301) from the first fluid pipe (2209). The flocculant is slowly added to the adsorbed copper grinding water through the seepage block (2404) under the feed hopper (2405) to promote the flocculation and precipitation of copper ions. The adsorbed copper grinding water is triple-screened using a coarse screen (2406), a fine screen (2407), and a carbon filter (2408). At this time, the third motor (2304) is activated to rotate the transmission wheel (2305), which drives the third rotating shaft (2308) to rotate the guide plate (2309), so that the newly added flocculated water can be screened. The copper-based flocculant is stirred in the guide vane (2309) and mixed with other copper-based flocculants. The displacement of the push-pull rod (2402) by the cylinder (2401) continuously changes the dosing point of the flocculant. At the same time, the scraper (2403) cleans the top of the coarse screen (2406) to prevent blockage. The upward flow of liquid from the guide vane (2309) cleans the area of ​​the coarse screen (2406) at the bottom of the third rotating shaft (2308), floats the impurities on the top of the coarse screen (2406) and throws them to the periphery according to the centrifugal force. The scraper (2403) then concentrates and cleans them to the left and right sides of the filter box (2301). S4. Returning filtered water: The filtered copper polishing water flows out in a concentrated manner through the second fluid pipe (2410) and the inclined plate (2409). It is then purified through multiple processes, including centrifugal separation and activated carbon filter. The treated clean water is then returned to the polishing equipment for recycling.
