Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper sulfate mother liquor purification technology, and more specifically, it relates to a copper sulfate mother liquor purification device. Background Technology
[0002] In the chemical industry, the purification of copper sulfate mother liquor is a crucial step that directly affects product quality and production efficiency. However, the copper sulfate mother liquor purification devices currently on the market still have serious technical defects in practical applications. These problems not only affect processing efficiency but may also lead to equipment damage and environmental pollution.
[0003] The primary problem is the scaling on the inner wall of the treatment tank. During the treatment of copper sulfate mother liquor, the solution contains a large number of impurities and metal ions, which easily form stubborn scale on the inner wall of the treatment tank. This scaling not only reduces heat transfer efficiency and affects the treatment effect, but may also lead to equipment corrosion and shorten its service life. More seriously, the lack of an effective scaling removal mechanism in the existing technology makes this problem increasingly serious. As the scaling layer continues to thicken, it will not only affect the volume of the treatment tank, but may also cause pipeline blockage and even safety accidents. In addition, manual cleaning is not only time-consuming and labor-intensive, but may also damage the equipment due to improper operation.
[0004] Secondly, low solid-liquid separation efficiency is another prominent problem. In the purification process of copper sulfate mother liquor, effective separation of solid impurities and liquid is a key step to ensure the purification effect. However, the separation mechanism in the existing technology is often inefficient and cannot achieve automated and continuous operation. This requires additional manual operation to complete the solid-liquid separation, which not only increases labor intensity and production costs, but may also lead to incomplete separation due to human factors, affecting the quality of the final product. In addition, frequent manual intervention also increases the risk of operators coming into contact with harmful substances, posing potential safety hazards.
[0005] Finally, existing equipment has significant shortcomings in heating control. Temperature control is crucial for reaction efficiency and product quality during the processing of copper sulfate mother liquor. However, existing heating devices are often simple in structure. This crude heating method not only fails to guarantee the temperature stability of the process, but may also lead to local overheating or uneven heating, affecting the reaction effect. More seriously, unstable temperature control may trigger side reactions, produce harmful gases, or reduce product purity. In addition, low energy efficiency is also a common problem, increasing production costs and environmental burden. Utility Model Content

[0016] Compared with the prior art, the present invention provides a copper sulfate mother liquor purification device, which has the following beneficial effects:
[0017] 1. The innovative design of the treatment device cleverly solves the problem of difficult scaling removal from the inner wall of the treatment tank. Through the precise coordination of the rotating shaft, scraper, scraper block, and mixing plate, a reliable automatic cleaning system is formed. The motor drives the rotating shaft to rotate, which drives the mixing plate to stir. This not only promotes heat transfer inside the solution and avoids local overheating, but also enhances the convection transfer of substances and improves the reaction rate. The scraper block on the outside of the mixing plate can continuously remove the scaling from the inner wall of the treatment tank during rotation. At the same time, the scraper at the bottom of the rotating shaft can also effectively remove the scaling from the inner wall of the conical part at the bottom of the treatment tank. This design not only avoids the tediousness and risks of manual cleaning, but also prevents the deposition of solid particles through continuous stirring, fundamentally reducing the possibility of scaling on the equipment.
[0018] 2. The innovative design of the separation device solves the problem of low efficiency in solid-liquid separation. Through the ingenious combination of the separation chamber, processing chamber, conveying pipe, conveying chamber, guide block, and filter holes, a highly efficient automatic separation system is formed. After the reaction is completed, the valve is opened to allow the reaction liquid to enter the separation chamber. The inclined structure design of the guide block allows the liquid and solid to flow automatically to the filter hole side. The liquid enters the conveying chamber through the filter hole and is transported to the subsequent processing equipment through the conveying pipe, while the solid is effectively intercepted in the separation chamber. This design not only realizes the automation and continuous operation of solid-liquid separation, but also avoids manual intervention, greatly improves the separation efficiency, and reduces the risk of operators coming into contact with harmful substances.
[0019] 3. The design of the heating device effectively solves the problem of unstable heating control. Through the precise coordination of heat exchange tubes, input tubes, output tubes, and heaters, a stable and controllable heating system is formed. After the heater heats the hot water to a suitable temperature, the hot water is transported to the heat exchange tubes arranged in a spiral structure by a delivery pump. The unique spiral structure design of the heat exchange tubes ensures uniform heating of the treatment tank and avoids local overheating. This design achieves precise temperature control. The setting of re-transporting the used hot water to the heater through the output tube connected to the output end of the heat exchange tubes improves energy utilization efficiency. At the same time, the spiral heat exchange structure increases the heat exchange area, ensuring the stability and uniformity of the heating effect. Attached Figure Description

The processing tank 2 is detachably mounted on the support frame 1, the tank cover 3 is detachably mounted on the top of the processing tank 2, the rotating shaft 4 is rotatably mounted inside the processing tank 2, the scraper 5 is connected to the outer side of the bottom end of the rotating shaft 4, the scraper block 6 is fixedly mounted on the outer side of the mixing plate 7, the mixing plate 7 is detachably mounted on the outer side of the rotating shaft 4, a heating device is installed on the outer side of the processing tank 2, and a separation device is provided below the processing tank 2. The separation device includes a separation chamber 8, a processing chamber 9, a conveying pipe 10, a conveying chamber 11, a guide block 12, and filter holes 13.

[0030] The bottom of the processing tank 2 is detachably connected to a valve 14, and the bottom of the valve 14 is detachably connected to the top of the separation chamber 8.
[0031] The top of the can lid 3 is fixedly provided with a feeding hopper 15, and a detachable cover 16 is provided above the feeding hopper 15.
[0032] A handle 17 is fixedly provided on the top of the cover 16 and on one side of the separation compartment 8.
[0033] The top of the can lid 3 is detachably equipped with a motor 18, and the output end of the motor 18 is connected to the top of the rotating shaft 4.
[0034] Both the outer side of scraper 6 and the outer side of scraper 5 are in contact with the inner wall of treatment tank 2.
[0035] In this embodiment, when the equipment is needed, the cover 16 is first removed from the feed hopper 15 using handle 17. Then, the raw material is added to the processing tank 2 through the feed hopper 15. The cover 16 is then reinstalled onto the feed hopper 15. The motor 18 is then turned on, causing the rotating shaft 4 connected to the output end of the motor 18 to rotate. This rotating shaft 4 drives the mixing plate 7 to rotate, thus stirring the raw material, promoting heat transfer within the solution, preventing localized overheating, ensuring uniform overall temperature, enhancing convection transfer of substances, increasing contact opportunities between reactants, accelerating the reaction rate, and preventing solid particle deposition, reducing equipment scaling. Furthermore, the mixing plate 7 drives the scraper 6 on the outer side to rotate, causing the scraper 6 to remove scale from the inner wall of the processing tank 2. During the scraping process, the rotating shaft 4 drives the scraper 5 at the bottom to rotate, and the scraper 5 scrapes away the scale on the inner wall of the conical part at the bottom of the treatment tank 2, effectively cleaning the scale. After the reaction is complete, the valve 14 at the bottom of the treatment tank 2 is opened, and the reacted liquid and solid will enter the separation chamber 8 in the treatment chamber 9 through the valve 14. Due to the inclined structure design of the guide block 12, the liquid and solid will move together to the side near the filter hole 13 of the separation chamber 8. Then the liquid enters the conveying chamber 11 through the filter hole 13, while the solid is intercepted inside the separation chamber 8, achieving solid-liquid separation. The liquid that enters the conveying chamber 11 will be transported to the subsequent external treatment equipment through the conveying pipe 10 connected to one side of the conveying chamber 11.
[0036] Please see Figure 1 , Figure 2 and Figure 5 As one embodiment of the heating device: the heating device includes a heat exchange tube 19, an input tube 20 and an output tube 21. The heat exchange tube 19 is arranged in a spiral structure on the outside of the processing tank 2. One end of the input tube 20 is detachably connected to the input end of the heat exchange tube 19, and one end of the output tube 21 is detachably connected to the output end of the heat exchange tube 19.
[0037] A heater 22 is detachably installed on one side of the bracket 1. The output end of the heater 22 is connected to the other end of the input pipe 20, and the input end of the heater 22 is connected to the other end of the output pipe 21.
[0038] More specifically, when the equipment is in use, the heater 22 is first turned on to heat the hot water inside the heater 22 to a suitable temperature. Then, the built-in delivery pump in the heater 22 is turned on, allowing the heater 22 to deliver the heated hot water to the input pipe 20, and then to the heat exchange tube 19 located on the outside of the treatment tank 2. The heat exchange tube 19 exchanges heat with the treatment tank 2, heating the side wall of the treatment tank 2, thereby heating the inside of the treatment tank 2. Due to the unique spiral structure design of the heat exchange tube 19, stable and uniform heating of the treatment tank 2 is achieved, ensuring the treatment effect. After use, the hot water is returned to the heater 22 through the output pipe 21 connected to the output end of the heat exchange tube 19, realizing resource recycling.
[0039] In summary, when using or operating the equipment: First, remove the hopper cover 16 from the feed hopper 15 using handle 17. Then, add the raw materials into the processing tank 2 through the feed hopper 15. Next, reinstall the hopper cover 16 onto the feed hopper 15. Then, turn on the motor 18, causing the rotating shaft 4 connected to the output end of the motor 18 to rotate. This rotating shaft 4 then drives the mixing plate 7 to rotate, thus agitating the raw materials, promoting heat transfer within the solution, preventing localized overheating, ensuring uniform overall temperature, enhancing convection transfer of substances, increasing contact opportunities between reactants, accelerating the reaction rate, and continuous agitation prevents solid particle deposition and reduces equipment scaling. Furthermore, the mixing plate 7 drives the scraper 6 on the outer side to rotate, causing the scraper 6 to scrape the inner wall of the processing tank 2. The scale is scraped off, and the rotating shaft 4 drives the scraper 5 at the bottom to rotate. The scraper 5 scrapes off the scale on the inner wall of the conical part at the bottom of the treatment tank 2, achieving effective cleaning of the scale. After the reaction is completed, the valve 14 at the bottom of the treatment tank 2 is opened. The reacted liquid and solid will then enter the separation chamber 8 in the treatment chamber 9 through the valve 14. Due to the inclined structure design of the guide block 12, the liquid and solid will move together to the side near the filter hole 13 in the separation chamber 8. The liquid will then enter the conveying chamber 11 through the filter hole 13, while the solid will be intercepted inside the separation chamber 8, achieving solid-liquid separation. The liquid that enters the conveying chamber 11 will then be conveyed to the subsequent external treatment equipment through the conveying pipe 10 connected to one side of the conveying chamber 11.
[0040] When the equipment is in use, the heater 22 is first turned on to heat the hot water inside the heater 22 to a suitable temperature. Then, the built-in delivery pump in the heater 22 is turned on, allowing the heater 22 to deliver the heated hot water to the input pipe 20, and then to the heat exchange tube 19 located on the outside of the treatment tank 2. The heat exchange tube 19 exchanges heat with the treatment tank 2, heating the side wall of the treatment tank 2, thereby heating the inside of the treatment tank 2. Due to the unique spiral structure design of the heat exchange tube 19, stable and uniform heating of the treatment tank 2 is achieved, ensuring the treatment effect. After use, the hot water is returned to the heater 22 through the output pipe 21 connected to the output end of the heat exchange tube 19, realizing resource recycling.
