Description
Technical Field

[0002] The full name of a closed tower is a closed cooling tower, also known as an evaporative air cooler or a closed cooling tower. A tubular heat exchanger is placed inside the tower, and the cooling effect is ensured through the heat exchange of the flowing air, sprayed water, and circulating water. Since it is a closed cycle, it can ensure that the water quality is not polluted, well protecting the efficient operation of the main equipment and increasing the service life. When the outside air temperature is relatively low, the sprayed water system can be stopped to achieve water-saving effects. With the implementation of the national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in industries such as metallurgy, aviation, electric power, chemical engineering, and machinery in recent years.

However, when most existing closed towers are in use, they often lack corresponding cleaning mechanisms, resulting in a relatively short service life of their spraying systems. Moreover, most air cooling mechanisms are vertically installed inside the tower, which often affects the use of the air cooling mechanism during rainy and snowy weather and reduces the cooling efficiency.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the specification drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Referring to Figures 1-3 , an embodiment provided by the present utility model: A closed tower with a self-cleaning structure includes a tower body 1. The bottom of the inner wall of the tower body 1 is fixedly connected with a water tank 16. The water inlet of the water tank 16 is connected with a hopper 15. The side of the hopper 15 is fixedly connected to the inner wall of the tower body 1. A filter screen 17 is fixedly connected inside the water tank 16. A motor 9 is fixedly connected to one side of the tower body 1. The output end of the motor 9 penetrates the tower body 1 and is fixedly connected with a push rod 19 to the water tank 16. One end of the push rod 19 is fixedly connected with a fixed plate 18. A cleaning brush 20 is arranged on the side of the fixed plate 18 close to the filter screen 17. A cleaning brush 20 is arranged on the side of the fixed plate 18 close to the water outlet of the hopper 15. A filter screen is arranged at the water outlet of the hopper 15; A water pump 11 is fixedly connected to one side of the tower body 1. The water inlet of the water pump 11 is fixedly connected with a water inlet pipe 21. One end of the water inlet pipe 21 is connected inside the water tank 16. The water outlet of the water pump 11 is fixedly connected with a water pipe 10. The water outlets of the water pipe 10 are evenly fixedly connected with sprinkler heads 14.
[0023] Specifically, the cooling liquid sprayed out is recovered into the water tank 16 through the funnel 15. The operation of the motor 9 drives the push rod 19, which in turn drives the fixed plate 18 to perform linear motion back and forth. Thus, the cleaning brush 20 on the upper side of the fixed plate 18 is used to clean the filter screen at the water outlet of the funnel 15, and the cleaning brush 20 on the left side of the fixed plate 18 is used to clean the filter net 17 inside the water tank 16, achieving self-cleaning of the filtration system and improving the utilization efficiency of the cooling liquid. The cooling liquid is pumped out from the inside of the water tank 16 by the water pump 11 and sprayed on the coil 13 through multiple nozzles 14 at the water outlet of the water pipe 10, effectively cooling the object to be cooled inside the coil 13.
[0024] One side of the tower body 1 is fixedly connected with a fan 5. The output end of the fan 5 is fixedly connected with an air inlet pipe 22. An air filter screen is arranged at the air inlet of the fan 5. The bottom of the air inlet pipe 22 is located above the nozzle 14. The side of the air inlet pipe 22 is fixedly connected to the inner wall of the tower body 1. The middle of the air inlet pipe 22 is fixedly connected with an air outlet pipe 4. One side of the tower body 1 is fixedly connected with a feed pipe 6. One end of the feed pipe 6 is fixedly connected with a coil 13. One side of the tower body 1 is fixedly connected with a discharge pipe 7. One end of the discharge pipe 7 is fixedly connected with a coil 13. The surface of the coil 13 is located below the nozzle 14. One side of the tower body 1 is fixedly connected with a sewage discharge pipe 8. One end of the sewage discharge pipe 8 is located inside the water tank 16, and the other end of the sewage discharge pipe 8 is provided with a valve. The top of the inner wall of the tower body 1 is fixedly connected with a mist-catching net 12. The bottom of the mist-catching net 12 is located above the air inlet pipe 22. The middle of the mist-catching net 12 is fixedly connected with an air outlet pipe 4. One end of the air outlet pipe 4 penetrates through the tower body 1 and is fixedly connected to the top of the tower body 1. The top of the tower body 1 is evenly fixedly connected with supports 2, and the top ends of the supports 2 are fixedly connected with a protective cover 3.
[0025] Specifically, through the operation of the fan 5, air is sent into the inside of the box body 1 from the air inlet pipe 22, and the coil 13 is air-cooled from top to bottom. Heat exchange ventilation is carried out through the air outlet pipe 4. While air-cooling, it effectively avoids affecting the air-cooling efficiency in rainy and snowy weather. The object to be cooled is sent into the coil 13 through the feed pipe 6, and the object cooled in the coil 13 is sent out through the discharge pipe 7. After the fixed plate 18 is cleaned, the contaminated cooling liquid is discharged through the sewage discharge pipe 8. The mist generated by spraying the cooling liquid is intercepted by the mist-catching net 12, improving the utilization efficiency of the cooling liquid. The air outlet pipe 4 is protected to a certain extent by the protective cover 3 to prevent rain and snow from entering the air outlet pipe 4 in rainy and snowy weather.
[0026] Working principle: When using a closed cooling tower, the object to be cooled is sent into the coil 13 through the feed pipe 6. Then, the cooling liquid is pumped out from the inside of the water tank 16 by the water pump 11, and the coil 13 is sprayed through multiple nozzles 14 at the water outlet of the water pipe 10, which can effectively cool the object to be cooled inside the coil 13. Then, through the operation of the fan 5, the air is sent into the inside of the box body 1 from the air inlet pipe 22, and the coil 13 is cooled by air from top to bottom. Heat exchange ventilation is carried out through the air outlet pipe 4. While cooling by air, it effectively avoids affecting the air-cooling efficiency in rainy and snowy weather. The mist generated by the sprayed cooling liquid is intercepted by the mist-catching net 12, improving the utilization efficiency of the cooling liquid. The sprayed cooling liquid is recovered into the water tank 16 through the funnel 15. Through the operation of the motor 9, the push rod 19 is driven, and then the fixed plate 18 is driven to perform a linear movement back and forth. Thus, the filter screen at the water outlet of the funnel 15 is cleaned by the cleaning brush 20 on the upper side of the fixed plate 18, and the filter net 17 inside the water tank 16 is cleaned by the cleaning brush 20 on the left side of the fixed plate 18, which can achieve self-cleaning of the filtration system and improve the utilization efficiency of the cooling liquid. Then, the cooled object inside the coil 13 is sent out through the discharge pipe 7.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
