Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning cooling circulating water systems, in particular to a condenser rubber ball cleaning device which prevents ball leakage. Background Art

[0002] After long-term use, the cooling water circulation system of a central air conditioner is prone to fouling the heat exchange tube walls of the condenser, reducing the heat transfer efficiency of the heat exchanger and increasing the system's energy consumption. Therefore, it is necessary to clean the condenser. Currently, condenser cleaning methods are divided into chemical cleaning and physical cleaning. Although chemical cleaning methods can quickly remove dirt in some cases, their inherent shortcomings, such as incomplete cleaning, potential corrosion to equipment materials, and the complexity of subsequent sewage treatment, limit their widespread application. In view of this, the industry generally tends to use physical cleaning methods, especially cleaning technologies centered around rubber ball cleaning devices, which are highly favored due to their environmental friendliness, high efficiency, and minimal damage to equipment.

[0003] The traditional rubber ball cleaning device mainly includes components such as a ball storage device, a ball delivery pipeline, a condenser, a ball catcher and a ball return pipeline. The device introduces the rubber balls in the ball storage device into the water inlet end of the condenser through the ball delivery pipeline. Then, under the action of water flow pressure, the rubber balls roll along the inner wall of the heat exchange tube, effectively scraping and removing the dirt on the tube wall. The rubber balls that complete the cleaning task are then captured by the ball catcher set at the water outlet end of the condenser and returned to the ball storage device through the ball return pipeline for use in the next round of cleaning cycle.

[0004] However, the quality of the rubber balls currently circulating on the market is uneven. Some rubber balls will gradually reduce in size due to wear in the early stages of cleaning, and traditional ball catchers often use ball catchers with fixed apertures. In order to ensure water flow, the aperture size is usually large. Therefore, when faced with rubber balls with reduced volume, they are often unable to effectively capture them, resulting in frequent ball leakage. This not only reduces cleaning efficiency and increases cleaning costs, but may also have an adverse effect on the long-term stable operation of the condenser. Utility Model Content

[0010] The tank body is provided with a driving mechanism, which is used to drive the rotating rod to rotate, so as to drive the ball blocking rod to move to the middle of the ball blocking hole, thereby dividing the ball blocking hole into two small ball blocking areas.

DETAILED DESCRIPTION

[0028] The specific technical solutions of the present invention are further described below so that those skilled in the art can further understand the present invention, but it does not constitute a limitation to their rights.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the utility model.

[0030] Please refer to Figure 1-2 A leak-proof condenser rubber ball cleaning device comprises a ball storage device 1 and a ball catcher 2. The ball storage device 1 is arranged at the water inlet end of the condenser 26, and the ball catcher 2 is arranged at the water outlet end of the condenser 26. The ball storage device 1 is provided with a water inlet, a ball outlet and a ball return port. The water inlet and the ball outlet are connected to the water inlet pipe of the condenser 26 through a water inlet branch pipe 3 and a ball outlet branch pipe 4 respectively.

[0031] The ball catcher 2 includes a tank body 5 fixedly mounted on the water outlet pipe of the condenser, a ball catcher cover 6 in the shape of an inverted cone coaxially arranged in the tank body 5, the ball catcher cover 6 is fixedly connected to the inner wall of the tank body 5, the lower end of the ball catcher cover 6 is connected to a ball collecting chamber 7, one side of the ball collecting chamber 7 is provided with an outlet, and the outlet is connected to the ball return port of the ball storage device 1 through a ball return branch pipe 8;

[0032] Please refer to Figure 3-5The ball-catching cover 6 is circumferentially arranged with several rows of ball-blocking holes 9 (in this embodiment, there are 18 rows, each row containing 6 balls). The diameter of these holes 9 is smaller than the diameter of the rubber balls, enabling them to intercept and capture rubber balls in the water flow. A rotating rod 10 is coaxially mounted in the center of the ball-catching cover 6. An annular frame 11 is fixedly attached to the outer side of the rotating rod 10. A plurality of ball-blocking rods 12 are evenly distributed circumferentially on the annular frame 11. Each ball-blocking rod 12 is attached to the inner wall of the ball-catching cover 6 and corresponds to a row of ball-blocking holes 9. Therefore, the number of ball-blocking rods 12 is the same as the number of rows of ball-blocking holes 9.

[0033] The tank body 5 is provided with a driving mechanism for driving the rotating rod 10. The driving mechanism drives the rotating rod 10 to rotate, and the rotating rod 10 drives the annular frame 11 and the ball blocking rod 12 to move, so that the ball blocking hole 9 of the original fixed aperture can be effectively divided into two smaller ball blocking areas, thereby improving the ability to capture the rubber ball of reduced size.

[0034] Please refer to Figure 1 To achieve pipeline opening and closing control, the water inlet valve 13 is installed on the water diversion branch pipe 3, and a ball pump 14 is installed between the water inlet valve 13 and the ball reservoir 1. The ball outlet branch pipe 4 is equipped with a ball outlet valve 15, and the ball return branch pipe 8 is equipped with a ball return valve 16. A ball return pump 17 is installed between the ball return valve 16 and the ball reservoir 1. In this way, the opening and closing of the cleaning device pipeline can be controlled by the water inlet valve 13, the water outlet valve, and the ball return valve 16. The ball pump 14 and the ball return pump 17 provide additional power for ball delivery and collection, maintaining stable operation of the device even when the water flow rate is low.

[0035] To achieve automatic adjustment of the ball-blocking rod 12, a ball counter 18 is provided on the ball-returning branch pipe 8. This includes a controller 19, which is in communication with both the ball counter 18 and the drive mechanism and can control the start and stop of the drive mechanism based on the output of the ball counter 18. When the controller 19 detects that the number of balls returned is lower than the set number of balls pitched, indicating ball leakage, the controller 19 automatically activates the drive motor 27, moving the ball-blocking rod 12 to the ball-blocking hole 9 for enhanced interception. Otherwise, the rod 12 is maintained or adjusted to a spaced position to reduce water flow resistance and automatically optimize ball capture efficiency. While the ball counter 18 is conventional, a photoelectric detection ball counter 18 such as that described in CN115077293A is preferred.

[0036] In the above structure, the water inlet valve 13, the ball outlet valve 15 and the ball return valve 16 are all electric valves, and the controller 19 is communicated with the water inlet valve 13, the ball outlet valve 15, the ball return valve 16, the ball pump 14 and the ball return pump 17 respectively.

[0037] Please refer to Figure 2An upper shaft seat 20 is fixed to the upper end of the ball catching cover 6, and a lower shaft seat 21 is fixed to the lower end of the ball collecting chamber 7. The two ends of the rotating rod 10 are respectively rotatably installed in the upper shaft seat 20 and the lower shaft seat 21 to ensure that the rotating rod 10 can rotate smoothly.

[0038] In the above structure, a transmission box 22 is fixedly mounted on the upper end of the ball-catching cover 6. The upper shaft seat 20 is fixedly mounted within the transmission box 22. A drive motor 27, which can be a servo motor, is fixedly mounted on the tank 5 on one side of the transmission box 22. The output end of the drive motor 27 is connected to a transmission shaft. The other end of the transmission shaft extends into the transmission box 22 and is connected to the rotating rod 10 via a bevel gear structure. To reduce water resistance, the top of the transmission box 22 is provided with a curved top.

[0039] Please refer to Figure 5 The annular frame 11 includes at least two upper and lower mounting rings 23 (three upper, middle and lower ones are provided in this embodiment), each mounting ring 23 is fixedly connected to the rotating rod 10 through a connecting rod 24 (five in this embodiment), and the ball blocking rod 12 is fixedly set on the mounting ring 23. The mounting ring 23 can keep the annular frame 11 and the ball blocking rod 12 stable during rotation.

[0040] In the above structure, the ball blocking rod 12 includes a main body fixedly connected to the mounting ring 23, and a cleaning sponge 25 mounted on the outside of the main body and abutting against the inner wall of the ball catcher 6. To clean the ball catcher 6, there is no need to remove it. Simply start the drive motor 27, causing the rotating rod 10 to rotate the annular frame 11 and the ball blocking rod 12. Because the cleaning sponge 25 is mounted on the ball blocking rod 12, as the rod 12 rotates, the cleaning sponge 25 rubs against the inner wall of the ball catcher 6, thereby removing dirt and impurities adhering to the inner wall. This not only improves cleaning efficiency but also avoids the risk of sealing degradation or damage that could occur due to frequent disassembly and assembly of the ball catcher 6.

[0041] Working Principle: This utility model provides a leak-proof condenser ball cleaning device. To use it, the number of balls to be dispensed is input into controller 19, which then activates the device. Controller 19 first opens water inlet valve 13, allowing cooling water to enter ball reservoir 1. Ball pump 14 then activates, pumping the balls and water from reservoir 1 through ball outlet branch pipe 4 into the condenser's water inlet pipe. At this point, ball outlet valve 15 also opens, ensuring that the balls and water flow smoothly into condenser 26 for cleaning.

[0042] Inside the condenser 26, the rubber balls flow into the heat exchange tubes with the water, using their elasticity and hardness to clean the tube walls, removing attached dirt and microorganisms. The cleaned rubber balls and the water flow continue to flow forward, eventually entering the ball catcher 2 located at the water outlet of the condenser.

[0043] After being intercepted by the ball-catching cover 6 in the ball trap 2 and passing through its ball-blocking hole 9, the rubber balls fall into the ball-collecting chamber 7 below. They are then pumped back into the ball reservoir 1 via the ball-returning branch pipe 8 by the ball-returning pump 17. At this point, the ball-returning valve 16 opens, allowing the rubber balls and water to pass through. The rubber ball counter 18 continuously records the number of balls returned during the current round and provides real-time feedback to the controller 19, enabling it to monitor and adjust the cleaning process.

[0044] When the cleaning cycle is complete, the controller 19 determines whether the number of returned balls matches the number of balls injected based on the feedback from the ball counter 18. If not, this indicates a "ball leak" phenomenon. The controller 19 then activates the drive motor 27, driving the rotating rod 10 to rotate. This rotation of the rotating rod 10 drives the ball blocking rod 12 to move to the middle of the ball blocking hole, thereby changing the effective diameter of the ball blocking hole 9. This enhances the interception capability for shrinking balls and ensures that all balls are effectively captured.

[0045] When all the rubber balls are recovered and re-enter the ball storage container 1, the controller 19 controls the water inlet valve 13, the ball outlet valve 15 and the ball return valve 16 to close, and stops the ball delivery pump 14 and the ball return pump 17. At this point, the cleaning process is completed, and the controller 19 returns to the standby state, waiting for the next cleaning instruction.

[0046] To keep the ball catcher 2 clean and operating efficiently, the device also features an automatic cleaning function. When cleaning the ball catcher 6 is needed, the motor 27 rotates the annular frame 11 and the ball blocking rod 12. Cleaning pads 25 mounted on the outside of the ball blocking rod 12 rub against the inner wall of the ball catcher 6, removing dirt and impurities adhering to the inner wall.

[0047] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
