Technical Field
[0001] This utility model relates to the field of sodium chloride evaporation and crystallization, and in particular to a sodium chloride evaporation and crystallization tank. Background Technology
[0002] In the chemical production field, sodium chloride, as an important chemical raw material and basic chemical, is widely used in evaporation crystallization processes in many industries such as chlor-alkali industry, food processing, and pharmaceutical manufacturing. The sodium chloride evaporation crystallization process is a key step in achieving the separation and purification of sodium chloride and obtaining high-quality crystalline products, and the sodium chloride evaporation crystallization tank, as the core equipment, plays a vital role in the entire production process.
[0003] Currently, existing sodium chloride evaporation crystallizers have many problems in practical use. On the one hand, during the evaporation crystallization process, sodium chloride crystals and dirt easily adhere to the inner wall and bottom of the tank. Over time, the accumulation of large amounts of crystals and dirt not only affects the heat transfer efficiency of the crystallizer and reduces the production efficiency of evaporation crystallization, but may also cause safety hazards due to local overheating. However, the existing crystallizer cleaning structure is often quite complex, making it inconvenient to disassemble and replace cleaning parts, and difficult to achieve timely and effective cleaning. On the other hand, in the sodium chloride crystallization discharge stage, most crystallizers lack an effective structure for precisely controlling the discharge amount, usually relying solely on manual experience for judgment and operation. This method easily leads to unstable discharge amounts. When the discharge amount is too high, it causes difficulties in subsequent collection and processing; when the discharge amount is too low, it affects production efficiency and cannot meet the needs of modern industrial production for precise control and high-efficiency production. To address this technical problem, this application proposes a sodium chloride evaporation crystallizer. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sodium chloride evaporation crystallization tank. In use, the support plate is connected to a scraper (or cleaning roller) via a tenon-and-mortise structure, a semi-circular threaded column, and a threaded cap, effectively cleaning the crystals (or dirt) on the inner wall and bottom of the tank. Compared to traditional manual cleaning and tool disassembly, this device is more convenient and faster. Sodium chloride crystals fall into a transparent storage tube through the discharge pipe. The storage tube is controlled by an electric push rod to move a sliding plate along a slide rail. When the required quantity is reached, the storage tube on the sliding plate moves away and blocks the discharge, achieving precise quantitative control.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sodium chloride evaporation and crystallization tank, comprising a sodium chloride evaporation and crystallization tank body, a motor is provided on the top outer wall of the sodium chloride evaporation and crystallization tank body, a fixing rod is provided at the bottom of the motor, a support plate is fixedly connected to the top outer wall of the fixing rod, a scraper is provided inside the top of the support plate, a semi-circular threaded column is fixedly connected to the outer wall of both the support plate and the scraper, a threaded cap is threadedly connected to the outer wall of the semi-circular threaded column, a discharge pipe is fixedly connected to the bottom of the sodium chloride evaporation and crystallization tank body, a bracket is provided on the outer wall of the discharge pipe, a slide rail is fixedly connected to the bottom of the bracket, a sliding plate is slidably connected inside the slide rail, a transparent storage tube is provided inside the sliding plate, an L-shaped base is provided at the bottom of the transparent storage tube, and the slide rail and the sliding plate are connected by an electric push rod.
[0006] Furthermore, a storage box is provided outside the motor, and a handle is provided on the outer wall of the storage box.
[0007] Furthermore, a movable plate is provided on the inner top wall of the sodium chloride evaporation crystallizer body, and a handle is fixedly connected to the outer wall of the movable plate.
[0008] Furthermore, a feed pipe is provided on the inner wall of the top of the sodium chloride evaporation crystallization tank body, and a steam outlet is provided on the inner wall of the top of the sodium chloride evaporation crystallization tank body.
[0009] Furthermore, a fixing block is fixedly connected to the outer wall of the side of the sodium chloride evaporation crystallizer body, and a support leg is provided on the outer wall of the fixing block.
[0010] Furthermore, a cleaning roller is provided inside the top of the support plate.
[0011] Furthermore, the bottom outer wall of the fixing rod is provided with fan blades.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, when using the sodium chloride evaporation crystallizer, the crystals and dirt attached to the inner wall and bottom of the sodium chloride evaporation crystallizer can be collected and cleaned by replacing the scraper or cleaning roller connected to the support plate. The support plate and scraper are connected to the semi-circular threaded column at the top through a tenon and mortise structure. Compared with traditional manual cleaning and disassembly with tools, this device is more labor-saving and faster.
[0014] 2. In this utility model, when the sodium chloride evaporation crystallizer is in use, the sodium chloride crystals fall into the transparent storage tube through the discharge pipe. Since the sliding plate and the slide rail on the transparent storage tube are connected by an electric push rod, when the amount of sodium chloride crystals in the transparent storage tube reaches the required amount, the electric push rod is activated. At this time, the transparent storage tube on the sliding plate moves away from the discharge pipe, and the sliding plate moves to the lower end of the discharge pipe to prevent the discharge pipe from continuing to discharge, thereby controlling the amount of sodium chloride crystals discharged.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figures 1-3A sodium chloride evaporation crystallization tank includes a tank body 1. A motor 2 is mounted on the top outer wall of the tank body 1. A fixing rod 3 is mounted on the bottom of the motor 2. A support plate 5 is fixedly connected to the top outer wall of the fixing rod 3. A scraper 6 is mounted inside the top of the support plate 5, and the scraper 6 is in close contact with the inside of the tank body to scrape off sodium chloride crystals adhering to the inner wall of the tank. Semi-circular threaded columns 7 are fixedly connected to the outer walls of both the support plate 5 and the scraper 6. A threaded cap 8 is threaded onto the outer wall of the semi-circular threaded column 7. A groove is formed at the top of the support plate 5. After the scraper 6 is installed in the groove of the support plate 5, the semi-circular threaded column 7 connected to the outer wall will align with the entire threaded column. The threaded cap 8 can then be manually tightened to secure it (because there is not much centrifugal force during stirring, manual tightening will not cause significant centrifugal force). (In case of detachment risk), the bottom of the sodium chloride evaporation crystallizer body 1 is fixedly connected to the discharge pipe 9. The outer wall of the discharge pipe 9 is provided with a support 10. The bottom of the support 10 is fixedly connected to the slide rail 11. The slide rail 11 is slidably connected to the slide plate 12. The slide plate 12 is provided with a transparent storage tube 14. The transparent storage tube 14 allows the operator to observe the storage status in real time. When the transparent storage tube 14 receives the required amount, the slide plate 12 can be slid along the slide rail 11 by the electric push rod 13 to remove the transparent storage tube 14 containing crystals. The bottom of the transparent storage tube 14 is provided with an L-shaped base 15, which provides stable support for the storage tube. The slide rail 11 and the slide plate 12 are connected by the electric push rod 13, which can flexibly adjust the position of the transparent storage tube 14.
[0023] Reference Figure 1 , Figure 2 , Figure 4The motor 2 is equipped with a placement box 16 on its exterior, and a handle 17 is provided on the outer wall of the placement box 16. The placement box 16 can also protect the motor 2 to a certain extent from damage caused by collisions, and the handle 17 facilitates opening and closing the placement box. The top inner wall of the sodium chloride evaporation crystallizer body 1 is equipped with a movable plate 21, and a handle 20 is fixedly connected to the outer wall of the movable plate 21. When the crystallization process is over or when the tank needs to be cleaned, the operator can pull the movable plate 21 through the handle 20. The scraper 6 and cleaning roller 24 can be easily installed through the opening of the movable plate 21. The top inner wall of the sodium chloride evaporation crystallizer body 1 is equipped with a feed pipe 18 and a steam outlet 19. The steam generated by evaporation is discharged through the steam outlet 19. The tank body ensures stable internal pressure and maintains a normal evaporation and crystallization environment. A fixing block 22 is fixedly connected to the outer wall of the side of the sodium chloride evaporation and crystallization tank body 1. The outer wall of the fixing block 22 is equipped with a support leg 23, which provides stable support for the entire equipment, ensuring that the equipment remains balanced during operation and avoiding the impact of shaking on the evaporation and crystallization effect and equipment safety. A cleaning roller 24 is installed inside the top of the support plate 5. When the tank needs to be cleaned, the cleaning roller 24 is installed to clean the stains attached to the inner wall of the tank, ensuring the cleanliness of the tank and avoiding the impact of crystallization stains on the service life and evaporation effect of the tank. A fan blade 4 is installed on the outer wall of the bottom of the fixing rod 3. The fan blade 4 stirs the solution, making the solution heat more evenly and accelerating the evaporation and crystallization process.
[0024] Working principle: When using this device, the sodium chloride evaporation crystallization tank body 1 is self-heating. After the sodium chloride solution to be treated is poured into the sodium chloride evaporation crystallization tank body 1 through the feed pipe 18, the heating is turned on and the motor 2 is started, which drives the fixed rod 3 to rotate. The fan blade 4 at the bottom of the fixed rod 3 stirs the solution, making the solution flow fully in the tank and heat more evenly, thereby accelerating the evaporation crystallization process. As the evaporation process proceeds, water evaporates continuously, and the generated steam is discharged from the tank through the steam outlet 19 to maintain stable pressure inside the tank and ensure a normal evaporation crystallization environment. After evaporation, some sodium chloride crystals will adhere to the inner wall of the tank. At this time, the fixed rod 3 drives the support plate 5 to rotate, and the scraper 6 installed on the support plate 5 is close to the inner wall of the tank. During the rotation, the attached sodium chloride crystals are scraped off. After crystallization is completed, the crystallized sodium chloride is discharged through the discharge pipe 9. The slide rail 11, slide plate 12, electric push rod 13, and transparent storage tube 14 located below the discharge pipe 9 work together. The electric push rod 13 pushes the slide plate 12 to slide on the slide rail 11, so that the transparent storage tube 14 on the slide plate 12 is accurately moved below the discharge pipe 9 to receive crystals. The operator can observe the storage status in real time through the transparent storage tube 14. When the required amount is reached, the electric push rod 13 moves again to remove the transparent storage tube 14 containing crystals. The slide plate 12 moves below the discharge pipe 9, so that the discharge pipe 9 will not continue to discharge. The L-shaped base 15 at the bottom of the storage tube 14 provides stable support for it. In addition, when the crystallization process is over or the tank needs to be cleaned, the operator can pull the movable plate 21 through the handle 20 to open the top opening and replace the scraper 6 with a cleaning roller 24. The installation method is similar to that of the scraper 6, and it is fixed by mortise and tenon structure and semi-circular threaded column 7 and threaded cap 8. The cleaning roller 24 rotates under the drive of the fixed rod 3 to clean the stains attached to the inner wall of the tank, ensuring the cleanliness of the tank and extending its service life. The external placement box 16 of the motor 2 can protect the motor 2 from collision damage. The handle 17 makes it convenient for operators to open and close the placement box 16. The fixed block 22 and support leg 23 on the side of the sodium chloride evaporation crystallization tank body 1 provide stable support for the entire equipment, ensuring the balance during the operation of the equipment and avoiding the impact of shaking on the evaporation crystallization effect and equipment safety.
