Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-cooled equipment technology, and in particular to a water-cooled crystallization tank with air-drying function. Background Technology
[0002] The copper sulfate water-cooled crystallization tank is a rapid cooling crystallization device for the electrolytic solution in copper sulfate production. It mainly consists of a stirring device, tank cover, tank body, and inner water jacket. The inner water jacket is equipped with cooling water inlet and outlet pipes, which improves heat exchange efficiency and greatly increases output. By coordinating and adjusting the flow rate of cooling water and the rotation speed of the stirring paddle, the cooling process can be effectively controlled, improving product quality. The amount of cooling water consumed in production is significantly reduced, and the power consumption of the cooling circulating water is also reduced, achieving the goal of energy saving and consumption reduction.
[0003] In existing copper sulfate water-cooled crystallization tanks, the basic principle of the device is to use stirring to cause copper ions and sulfate ions to form nuclei and aggregate for growth. During the stirring process, it is inevitable that these nuclei will adhere to the inner wall of the device. Once attached, these nuclei will continuously rub and collide with the stirring paddle and other components as stirring continues. This long-term mechanical action accelerates the wear and tear on the inner wall and stirring components, shortening the equipment's lifespan.
[0004] To address the issue of crystal nuclei adhering to the inner wall of the apparatus, a scraper is connected to the stirring mechanism. This scraper adheres closely to the inner wall, ensuring that while crystal nuclei precipitate during stirring, no nuclei remain inside the apparatus. The scraper promptly removes any adhering nuclei from the inner wall back into the solution, allowing them to re-participate in the crystallization process. This accelerates nucleation and growth, improves overall crystallization efficiency, and shortens the production cycle.
[0005] However, in the current process of extracting crystals, because the liquid and crystals fall simultaneously after the valve is opened, the solution that has not yet crystallized is wasted. The uncrystallized solution contains a certain amount of copper sulfate solute, which is lost with the waste liquid discharge. The waste of solute means an indirect waste of raw materials, increasing the pressure on resource extraction and the environmental burden. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-cooled crystallization tank with a drying function, which solves the problem of crystal nuclei adhering to the inner wall of the device.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A water-cooled crystallization tank with air-drying function includes a tank body. A rotary motor is mounted at the top of the tank body, and a connecting rod is fixedly connected to the output end of the motor. Multiple series plates are fixedly connected to the outer end of the connecting rod. Scrapers are fixedly connected to the ends of the series plates away from the connecting rod. The scrapers are used to clean the inner wall of the tank body. Several air vents are drilled through the interior of each scraper for drying the inner wall of the tank body. The connecting rod allows for simultaneous stirring of the copper sulfate solution and anti-adhesion treatment of the inner wall. The air vents generate airflow to rapidly dry the device after the nucleation crystals and copper sulfate solution are released through the valve.
[0009] As a further improvement of this utility model, a funnel inlet is fixedly connected to the top of the water-cooled crystallization tank body, a sealing plug is movably connected to the top of the funnel inlet, and a control valve is provided at the bottom of the water-cooled crystallization tank body. The control valve is used to close and open the opening at the bottom of the water-cooled crystallization tank body.
[0010] As a further improvement of this utility model, a protective frame is fixedly connected to the top center of the water-cooled crystallization tank body, the rotary motor is fixedly connected to the top inside of the protective frame, and several stirring blades are uniformly fixedly connected to the connecting rod on the outer surface of the bottom end of the series plate.
[0011] As a further improvement of this utility model, a liquid storage frame is fixedly connected to the bottom end of the water-cooled crystallization tank body. An inlet is opened at the top of the liquid storage frame corresponding to the water-cooled crystallization tank body. A nucleus collection frame is slidably connected inside the liquid storage frame. A handle is fixedly connected to the side of the nucleus collection frame away from the inside of the liquid storage frame. Several leakage holes are opened through the bottom end of the nucleus collection frame. The leakage holes allow the nucleus to be separated from the copper sulfate solution.
[0012] As a further improvement of this utility model, a liquid storage tank is provided inside the liquid storage frame at the bottom of the leakage hole, and an outlet pipe is fixedly connected to the side of the liquid storage frame at the side of the liquid storage tank. The outlet pipe allows the copper sulfate solution to be collected and reused.
[0013] Compared with the prior art, the advantages of this utility model are as follows:
[0014] 1. The scraper, while stirring the copper sulfate solution with the agitator, also moves along the inner wall of the water-cooled crystallization tank. This achieves the effect of stirring and precipitating crystals from the copper sulfate solution, while preventing crystals or copper sulfate solution from adhering to the inner wall surface of the water-cooled crystallization tank.
[0015] 2. By using the leakage hole, copper sulfate crystals and copper sulfate solution are separated, thus preventing the waste of copper sulfate solution, avoiding prolonged immersion of crystals in the solution, reducing the possibility of impurities adsorbed on the crystal surface, and ensuring the cleanliness of the crystals.
[0016] 3. By using the airflow generated by the rotation through the air vents, the drying capacity can be greatly accelerated, allowing the water-cooled crystallization tank to reach a dry state that can be reused more quickly, shortening the entire production cycle and increasing the number of production batches and output per unit time.

Detailed Implementation
[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0026] See attached document Figure 1 -Appendix Figure 6 A water-cooled crystallization tank with air-drying function includes a water-cooled crystallization tank body 101, a rotary motor 106, a scraper 109, a stirring plate 110, a vent 111, a liquid storage frame 201, a crystal collection frame 203, a leakage hole 205, and a liquid storage tank 206.
[0027] In use, the copper sulfate solution to be crystallized is first poured into the water-cooled crystallization tank body 101 through the funnel inlet 102. Then, the rotary motor 106 is started, which drives the connecting rod 107 to rotate. Since the outer surface of the connecting rod 107 is fixedly connected to the scraper 109 through the connecting plate 108, and several stirring blades 110 are fixedly connected to the outside of the connecting rod 107, the start of the rotary motor 106 will drive the stirring blades 110 to stir the copper sulfate solution, and at the same time, it will also drive the scraper 109 to scrape along the inner wall of the water-cooled crystallization tank body 101. This achieves the effect of stirring and crystallizing the copper sulfate solution while preventing crystals or copper sulfate solution from adhering to the inner wall surface of the water-cooled crystallization tank body 101. Preventing crystals from adhering to the inner wall of the water-cooled crystallization tank body 101 makes the stirring more uniform and efficient. During stirring, the solution flows fully, allowing copper and sulfate ions to diffuse and collide more rapidly throughout the system, increasing the nucleation rate and accelerating crystal formation and growth. This shortens the overall crystallization cycle and increases yield per unit time. Furthermore, the absence of crystal deposits on the inner wall of the water-cooled crystallization tank 101 prevents equipment malfunctions and blockages caused by crystal buildup, ensuring a stable and continuous crystallization process. This reduces production interruptions due to equipment cleaning or maintenance, improving production continuity and stability.
[0028] After copper sulfate solution is stirred and crystals precipitate inside the water-cooled crystallization tank 101, the control valve 104 is opened, allowing both the copper sulfate solution and crystals to fall through the inlet 202 into the crystal collection frame 203. The copper sulfate solution then leaks completely into the storage tank 206 through the drain hole 205. The crystal collection frame 203 is then pulled out using the handle 204 to obtain copper sulfate crystals. The copper sulfate solution in the storage tank 206 is then discharged through the outlet pipe 207, resulting in a solution with incompletely precipitated copper and sulfate ions. This prevents waste of the copper sulfate solution and ensures the cleanliness of the copper sulfate crystals. The solution with incompletely precipitated copper and sulfate ions, after flowing out of the storage tank 206 through the outlet pipe 207, can be recycled back to the processing stage as raw material to continue participating in the crystallization process. This recycling method avoids one-time discharge of the solution and maximizes the recovery of solutes from the solution. Furthermore, the copper sulfate solution and crystals fall into the crystal collection frame 203 through the inlet 202, and then the solution leaks into the storage tank 206 through the drain hole 205, achieving initial separation of the crystals and the solution. Subsequently, the crystals are extracted from the crystal collection frame 203 by the handle 204. This process avoids the crystals from being immersed in the solution for a long time, reduces the possibility of impurities adsorbed on the crystal surface, and ensures the cleanliness of the crystals.
[0029] After the crystallization and copper sulfate solution leak into the storage frame 201 through the control valve 104, the rotation of the connecting rod 107 does not stop immediately. The rotation of the connecting rod 107 drives the scraper 109 to continue rotating along the inner wall of the water-cooled crystallization tank body 101. Because of the air vent 111 penetrating inside the scraper 109, a gas storage tank is installed at the bottom of the connecting rod 107. The middle of the connecting rod 107 and the gas storage tank are connected by a sealed rotating connector. The control valve 104 simultaneously controls the opening of the gas storage tank. Inside the gas storage tank... Compressed air is transmitted to the air inlet 111 through air passages opened at the bottom of the connecting rod 107 and the middle of 108. This generates airflow along the inner wall of the water-cooled crystallization tank body 101 under the rotation of the rotary motor 106. The air inlet 111 is designed to be at a 30°-45° angle to the plane of the scraper 109, ensuring the blown airflow moves tangentially to the inner wall of the water-cooled crystallization tank body 101, reducing airflow rebound and enhancing water droplet removal. This results in rapid drying of the inner wall of the water-cooled crystallization tank body 101. Rapid drying of the inner wall reduces the time interval between the crystallization process and the next production preparation. Utilizing the airflow generated by rotation significantly accelerates moisture evaporation, allowing the equipment to reach a dry state for reuse more quickly, shortening the overall production cycle, and increasing the number of batches and output per unit time. Furthermore, the inner wall of the water-cooled crystallization tank body 101 is prone to corrosion if it remains damp for an extended period after contact with copper sulfate solution. The rapid drying of the inner wall of the water-cooled crystallization tank body 101 can remove moisture in time, reduce the risk of corrosion of the inner wall of the water-cooled crystallization tank body 101, thereby extending the service life of the equipment and reducing the frequency of equipment maintenance and replacement.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
