Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically a high-efficiency cooling tower system for aluminum alloy production lines. Background Technology

[0002] As is well known, cooling towers are a crucial component in aluminum alloy production, ensuring stable operation of production equipment and improving product quality. Cooling towers lower the temperature of high-temperature equipment or materials through heat exchange between cooling water and the outside air, thereby meeting the requirements of the production process. However, in practical applications, traditional cooling tower systems suffer from the following problems.

[0003] Impurities such as calcium and magnesium ion crystals and suspended solids may precipitate in the cooling water. These impurities will gradually deposit on the bottom and side walls of the cooling tower, forming scale. The accumulation of scale will not only affect the flow of cooling water and heat exchange efficiency, but may also cause wear and corrosion on the inner wall of the cooling tower, shortening the service life of the equipment. Traditional cooling tower cleaning methods usually rely on manual operation, which requires manual cleaning after shutdown, which is time-consuming and labor-intensive. As scale accumulates, the flow of cooling water is obstructed, and the heat exchange efficiency drops significantly, causing the cooling tower to fail to meet the high-efficiency cooling requirements of the aluminum alloy production line.

The descaling device includes a first motor, a central column, scrapers, a discharge trough, a second motor, a rotating shaft, a spiral conveyor wheel, a discharge pipe, and a control valve. The first motor is installed on the bottom wall of the cooling tower body. The output end of the first motor penetrates the bottom wall of the cooling tower body and extends to the central column installed inside the cooling tower body. Scrapers are installed at both ends of the central column. The bottom and side walls of the scrapers are tapered. The discharge trough is provided inside the cooling tower body.

[0023] 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.

[0024] Please see Figure 1-4A high-efficiency cooling tower system for aluminum alloy production lines includes a cooling tower body 1 and a descaling device. The descaling device is installed on the inner bottom wall of the cooling tower body 1, and a support frame 2 is installed on the outer bottom wall of the cooling tower body 1. The descaling device includes a first motor 3, a central column 4, scrapers 5, a discharge trough 6, a second motor 7, a rotating shaft 8, a spiral conveyor wheel 9, a discharge pipe 10, and a control valve 11. The first motor 3 is installed on the bottom wall of the cooling tower body 1, and the output end of the first motor 3 penetrates the bottom wall of the cooling tower body 1 and extends into the cooling tower body 1 where the central column 4 is installed. Scrapers 5 are installed at both ends of the central column 4. The bottom and side walls of plate 5 are both tapered. A discharge trough 6 is provided inside the cooling tower body 1. A rotating shaft 8 is rotatably installed inside the discharge trough 6. The second motor 7 is installed at one end of the rotating shaft 8 near the central column 4. A spiral conveyor wheel 9 is installed on the outer wall of the rotating shaft 8. A discharge pipe 10 is installed through the side wall of the cooling tower body 1, and a control valve 11 is installed on the outer wall of the discharge pipe 10. In this embodiment, during normal operation, the cooling water in the cooling tower body 1 circulates through a water pump, exchanging heat with the outside air to lower the temperature. During the cooling process, impurities such as calcium and magnesium ions may precipitate in the cooling water. Crystals and suspended solids gradually deposit at the bottom of the cooling tower body 1. When the scale buildup at the bottom of the cooling tower body 1 reaches a certain thickness, the descaling device is activated through the control system. The output of the first motor 3 drives the central column 4 to rotate, causing the scraper 5 to rotate and move along the bottom wall of the cooling tower body 1. Since the bottom and side walls of the scraper 5 are designed to be conical, it can effectively scrape up the dirt deposited at the bottom and side walls of the cooling tower body 1 and push it into the discharge trough 6 through the rotation of the scraper 5. The dirt then enters the discharge trough 6 due to gravity. At the same time, the second motor 7 is activated and the control valve 11 is opened. The second motor 7 drives the rotating shaft 8 to rotate, which in turn drives the screw conveyor wheel 9 to rotate. The screw conveyor wheel 9 then... The dirt collected from the scraper 5 is gradually pushed along the discharge chute 6 to the discharge pipe 10. The dirt is discharged from the outside of the cooling tower body 1 through the discharge pipe 10. After cleaning is completed, the control valve 11 is closed. After the cleaning device stops working, the cooling tower body 1 resumes normal cooling function. The conical bottom wall and side wall design of the scraper 5 can fully cover the bottom surface of the cooling tower body 1, ensuring that the dirt is cleaned without dead corners. The scraper 5 is driven by the first motor 3, and the screw conveyor wheel 9 is driven by the second motor 7 to realize the automatic collection and transportation of dirt without manual intervention, which improves work efficiency. The cleaning device can remove dirt in time, reduce wear and corrosion on the inner wall of the cooling tower body 1, and extend the service life of the equipment.

[0025] Preferably, in this embodiment, a climbing frame 12 is installed on one side wall of the cooling tower body 1. The climbing frame 12 provides a safe and convenient passage for workers to enter the cooling tower for inspection and maintenance operations without the need for additional ladders or other tools. Compared with temporary ladders, the fixed climbing frame 12 is more stable and reduces the safety risks caused by equipment instability.

[0026] Preferably, in this embodiment, the top end of the scraper 5 is provided with a groove 13. By providing a groove 13 at the top end of the scraper 5, the water flow resistance is reduced, thereby reducing the energy consumption of the first motor 3.

[0027] Preferably, in this embodiment, two sets of reinforcing rods 14 are symmetrically installed in the groove 13. The symmetrical installation of two sets of reinforcing rods 14 in the groove 13 can effectively enhance the overall rigidity of the scraper 5, prevent it from bending or breaking during operation, and thus extend the service life of the scraper 5. The symmetrical design of the reinforcing rods 14 makes the scraper 5 more evenly stressed, avoiding deviation or tilting caused by excessive stress on one side.

[0028] Preferably, in this embodiment, both the first motor 3 and the second motor 7 are servo motors. When the first motor 3 drives the scraper 5, the servo motor can achieve precise position, speed and torque control. The rotation angle and speed of the scraper 5 can be precisely controlled by the servo motor to ensure that the cleaning process is uniform and efficient. When the second motor 7 drives the spiral conveyor wheel 9, the rotation speed can be precisely adjusted to ensure the stability and accuracy of dirt conveying.

[0029] Preferably, in this embodiment, the control valve 11 is a ball valve. The ball valve can be fully opened or closed by rotating 90°, which is simple and quick to operate. During the cooling tower cleaning process, when it is necessary to discharge the dirt in time, the ball valve can be opened quickly to ensure that the dirt is discharged smoothly. The discharge pipe 10 in the cooling tower system needs to withstand a certain pressure for a long time. The high sealing performance of the ball valve can effectively prevent leakage and ensure the stability of the system.

[0030] Preferably, in this embodiment, support legs 15 are installed at the four corners of the bottom wall of the support frame 2. The support legs 15 are evenly distributed at the four corners of the support frame 2, which can evenly distribute the weight of the cooling tower to the ground. Cooling towers are usually large in volume and heavy in weight. The design of installing support legs 15 at the four corners can significantly improve the stability of the entire system and prevent the risk of tipping over due to the shift of the center of gravity or uneven ground.

[0031] Preferably, in this embodiment, the bottom wall of the support leg 15 is equipped with an mounting plate 16, and the mounting plate 16 has multiple sets of mounting holes 17. The mounting plate 16 is connected to the ground or other fixed structures (such as concrete foundations or steel frame platforms) through the multiple sets of mounting holes 17 to form a stable support. The multiple sets of mounting holes 17 can be used to firmly fix the mounting plate 16 to the ground with bolts or anchors to prevent the cooling tower from being affected by the outside world.
