Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a closed cooling tower for preventing condensation. Background Technology

[0002] Closed-circuit cooling towers are widely used in chemical, power, and HVAC industries due to their closed-circuit cooling advantages, but condensation problems during operation limit their operational stability and service life.

[0003] Traditional closed-circuit cooling towers lack automatic cleaning devices for their air intake filter plates, making them prone to blockage due to impurities, leading to decreased air intake efficiency. High-humidity air inside the tower cannot be expelled in time, and the accumulated humidity easily causes condensation, affecting heat exchange efficiency and corroding the tower's metal structure. Furthermore, the tower's insulation panels are often installed using bolts or adhesives, which is cumbersome and inconvenient to replace, accelerating heat loss and increasing the temperature difference between the inside and outside air, further exacerbating condensation and even damaging components due to condensation and freezing. Moreover, existing anti-condensation designs often only control humidity or temperature difference, failing to form a synergistic anti-condensation system and failing to address the condensation problem at its root. Therefore, developing a closed-circuit cooling tower that combines a highly efficient and clean filtration structure, convenient insulation panel installation, and the ability to control condensation from both humidity and temperature difference perspectives has become a pressing technical challenge for the industry. Utility Model Content

[0004] The main purpose of this invention is to provide a closed-type cooling tower that prevents condensation, which can effectively solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A closed-type cooling tower with anti-condensation features includes a cooling tower body, an air inlet chamber fixedly connected to the top of the cooling tower body, a filter plate fixedly connected to the inner side of the air inlet chamber, a servo motor fixedly connected to one side of the air inlet chamber, a cleaning component provided inside the air inlet chamber, and a fixing component provided on the side of the cooling tower body.

[0006] Preferably, the cleaning component includes two sets of movable slots formed inside the air inlet chamber, a movable plate slidably connected between the two sets of movable slots, a squeezing rod slidably connected to the outside of the movable plate, a U-shaped frame fixedly connected to one end of the squeezing rod near the filter plate, and a cleaning roller rotatably connected to the inside of the U-shaped frame.

[0007] Preferably, a reset spring A is provided at the top of the U-shaped frame, and the reset spring A is sleeved on the outside of the compression rod.

[0008] Preferably, one set of the movable slots is rotatably connected to a threaded screw, and the threaded screw is threadedly connected to the inner side of one end of the movable plate; the other set of the movable slots is fixedly connected to a limit rod, and the limit rod is slidably connected to the inner side of the other end of the movable plate; the threaded screw extends to the outer side of the air inlet and is fixedly connected to the output shaft of the servo motor.

[0009] Preferably, the fixing assembly includes multiple sets of Z-shaped plates fixedly connected to the side of the cooling tower body, a sliding rod is slidably connected to the front of the Z-shaped plate, a pressing plate is fixedly connected to one end of the sliding rod extending to the inner side of the Z-shaped plate, and a reset spring B is fixedly connected between the sliding rod and the Z-shaped plate.

[0010] Preferably, the Z-shaped plate has a threaded rotating rod threadedly connected to its front side, and the threaded rotating rod extends to one end of the inner side of the Z-shaped plate and is fixedly connected to the extrusion plate.

[0011] Preferably, two sets of air ducts are fixedly connected to the top of the cooling tower body near the air inlet chamber, and an exhaust fan is installed inside the air duct.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The cleaning component is driven by a servo motor to rotate the threaded screw, which in turn drives the moving plate to reciprocate linearly along the limit rod. The linkage squeeze rod and U-shaped frame make the cleaning roller roll tightly against the filter plate for cleaning. The reset spring A can elastically compensate for the wear of the cleaning roller, which not only achieves full-area cleaning of the filter plate, effectively removes impurities and avoids filter plate blockage, ensuring the air intake efficiency of the air inlet chamber, but also prevents the accumulation of high humidity air in the tower due to poor air intake, reducing the core conditions for condensation from the perspective of humidity control. At the same time, the rolling cleaning method is more efficient than traditional wiping, and the elastic compensation design can maintain a long-term stable cleaning effect and reduce the frequency of equipment maintenance.

[0013] 2. The fixing component pushes the extrusion plate along the slide bar by rotating the threaded rod. The return spring B assists the extrusion plate in tightly fitting the insulation board, which can quickly fix the insulation board to the outside of the cooling tower body, wrapping the tower body to reduce heat loss and reduce the temperature difference between the air inside the tower and the cold air outside. From the perspective of temperature difference regulation, it avoids water vapor condensation. With the buffering effect of the return spring B, it can also prevent excessive extrusion from damaging the insulation board or tower structure, improve the flexibility and adaptability of the insulation board fixing, and further enhance the anti-condensation effect of the cooling tower.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-2 As shown, an anti-condensation closed cooling tower includes a cooling tower body 1, an air inlet chamber 2 fixedly connected to the top of the cooling tower body 1, a filter plate 5 fixedly connected to the inside of the air inlet chamber 2, a servo motor 8 fixedly connected to one side of the air inlet chamber 2, a cleaning component 3 provided inside the air inlet chamber 2, a fixing component 6 provided on the side of the cooling tower body 1, and two sets of air ducts 4 fixedly connected to the top of the cooling tower body 1 near the air inlet chamber 2, with an exhaust fan 7 provided inside the air ducts 4. As described above, the cooling tower body 1 serves as the core carrier, with the air inlet 2 fixed at its top providing a channel for airflow. The filter plate 5 inside the air inlet 2 filters impurities in the air, preventing them from entering the tower and causing dirt accumulation and condensation. The servo motor 8 on one side of the air inlet 2 drives the inner cleaning component 3 to operate, continuously cleaning the filter plate 5 to ensure airflow efficiency and prevent high humidity air accumulation inside the tower due to poor airflow. Two sets of air ducts 4 fixed at the top of the cooling tower body 1 near the air inlet 2 are equipped with exhaust fans 7. After the exhaust fans 7 are started, they accelerate the airflow circulation inside the tower. Outside air is filtered through the air inlet chamber 2 and then enters the cooling tower body 1 to exchange heat with the internal medium. The air after heat exchange is quickly discharged through the air duct 4, which promptly removes the high humidity air inside the tower, reducing condensation conditions at the source. The fixing components 6 on the side of the cooling tower body 1 can quickly fix the insulation board, wrapping the tower body to reduce heat loss and reduce the temperature difference between the air inside the tower and the cold air outside, further preventing water vapor from condensing into condensation. The components work together to form a closed-loop airflow circulation and insulation protection system, achieving closed-loop cooling while solving the condensation phenomenon from the aspects of humidity control and temperature difference regulation.

[0018] like Figures 3-4 As shown, the cleaning component 3 includes two sets of movable slots 301 opened inside the air inlet chamber 2. A movable plate 304 is slidably connected between the two sets of movable slots 301. A squeezing rod 305 is slidably connected to the outside of the movable plate 304. A U-shaped frame 306 is fixedly connected to one end of the squeezing rod 305 near the filter plate 5. A cleaning roller 307 is rotatably connected to the inside of the U-shaped frame 306. A reset spring A308 is provided on the top of the U-shaped frame 306 and is sleeved on the outside of the squeezing rod 305. A threaded screw 302 is rotatably connected to the inside of one set of movable slots 301 and is threadedly connected to the inside of one end of the movable plate 304. A limit rod 303 is fixedly connected to the inside of the other set of movable slots 301 and is slidably connected to the inside of the other end of the movable plate 304. The threaded screw 302 extends to one end outside the air inlet chamber 2 and is fixedly connected to the output shaft of the servo motor 8. As described above, after the servo motor 8 starts, it drives the threaded screw 302 to rotate. The threaded screw 302 drives the moving plate 304, which is threaded to it, to move linearly back and forth along the limit rod 303 in another set of movable grooves 301. When the moving plate 304 moves, it simultaneously drives the outer slidingly connected extrusion rod 305 and the U-shaped frame 306 fixed at the end of the extrusion rod 305 to move. The reset spring A308 sleeved on the outside of the extrusion rod 305 continuously applies pressure to the U-shaped frame 306, so that the cleaning roller 307 rotatably connected to the inner side of the U-shaped frame 306 always rolls in close contact with the surface of the filter plate 5. This removes impurities on the filter plate 5 through rolling friction, and the elasticity of the reset spring A308 compensates for the wear of the cleaning roller 307, ensuring that the cleaning effect does not decrease. This achieves full-area cleaning of the filter plate 5, ensures the air intake efficiency of the air inlet chamber 2, avoids the accumulation of humidity in the tower due to impurities clogging it, and reduces condensation conditions from the root.

[0019] like Figures 5-6 As shown, the fixing component 6 includes multiple Z-shaped plates 601 fixedly connected to the side of the cooling tower body 1. A sliding rod 602 is slidably connected to the front of the Z-shaped plate 601. A pressing plate 603 is fixedly connected to one end of the sliding rod 602 extending to the inner side of the Z-shaped plate 601. A reset spring B605 is fixedly connected between the sliding rod 602 and the Z-shaped plate 601. A threaded rotating rod 604 is threadedly connected to the front of the Z-shaped plate 601, and the threaded rotating rod 604 extends to one end of the inner side of the Z-shaped plate 601 and is fixedly connected to the pressing plate 603. As described above, when the threaded rotating rod 604 is rotated, it pushes the pressing plate 603, which extends to and is fixed to the inside of the Z-shaped plate 601, to move. The pressing plate 603 simultaneously drives the sliding rod 602, which is slidably connected to the Z-shaped plate 601, to move. The sliding rod 602 can limit the pressing plate 603 to move only in a straight line, ensuring accurate alignment. At the same time, the reset spring B605 between the sliding rod 602 and the Z-shaped plate 601 undergoes elastic deformation as the sliding rod 602 moves, applying auxiliary pressure to the pressing plate 603 to make it tightly fit the insulation board. Ultimately, the insulation boards inside the two adjacent Z-shaped plates 601 are quickly fixed to the outside of the cooling tower body 1, wrapping the tower body to reduce heat loss, reduce the temperature difference between the air inside the tower and the outside cold air, and prevent water vapor from condensing into dew. The reset spring B605 can also buffer the pressure to prevent excessive compression from damaging the insulation board structure.

[0020] The working principle of this utility model is as follows: First, the servo motor 8 drives the threaded screw 302 to rotate. The threaded screw 302 pulls the moving plate 304 to move linearly back and forth along the limiting rod 303 in another set of movable slots 301. The moving plate 304 simultaneously drives the extrusion rod 305 and the U-shaped frame 306 to move. The reset spring A308, which is sleeved on the outside of the extrusion rod 305, applies pressure, causing the cleaning roller 307 in the U-shaped frame 306 to roll and clean the filter plate 5 tightly. This removes impurities and compensates for wear through elasticity, ensuring air intake efficiency and preventing the accumulation of high-humidity air inside the tower. The two sets of air ducts 4 at the top of the cooling tower body 1, near the air inlet hopper 2, contain exhaust fans 7, which accelerate airflow circulation. After being filtered from the outside, the air enters the tower and exchanges heat with the internal medium. After the heat exchange, the high-humidity air is quickly discharged through the air duct 4, reducing condensation conditions from a humidity perspective. At the same time, the fixing component 6 on the side of the cooling tower body 1 assists in temperature control and condensation prevention. By rotating the threaded rod 604 on the Z-shaped plate 601, the extrusion plate 603 is pushed to move along the slide rod 602. The elastic deformation of the reset spring B605 assists the extrusion plate 603 to press tightly against the insulation plate, so that the insulation plate is quickly fixed on the outside of the tower body, reducing heat loss, reducing the temperature difference between the inside and outside of the tower, and preventing water vapor condensation. All components form a closed-loop linkage, achieving closed-loop cooling and condensation prevention effects from two dimensions: humidity control and temperature difference regulation.
