Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a water-saving and antifreeze device for cooling towers. Background Technology

[0002] A cooling tower is a device used to cool hot water in industrial processes or air conditioning systems. It lowers the water temperature by exposing the hot water to air, utilizing physical processes such as evaporation and convection.

[0003] During the operation of a cooling tower, although exhaust fans are used to remove heat and water vapor, sometimes the water vapor content in the air is too high, and the exhaust fans cannot completely remove all the water vapor. In this case, some water vapor condenses at the top of the cooling tower, forming water droplets. These condensed water droplets are not effectively utilized, which is detrimental to water conservation. Utility Model Content

[0004] The purpose of this invention is to provide a water-saving and antifreeze device for cooling towers. By using this device, the problem of water droplets condensed at the top of the cooling tower not being effectively utilized, which is not conducive to water conservation, is solved.

One end of the double-ended pipe is fixedly inserted into the collection box, and the other end of the double-ended pipe is fixedly inserted into the tower body. The first water pipe is fixedly inserted through the tower body, and the spray pipe is located inside the tower body.

Body 1, gear 54 and rack 56 are meshed and connected, the top of guide plate 58 is in contact with the bottom of collection plate 57. By setting collection plate 57, water droplets will accumulate at the bottom of collection plate 57. The first motor 52 drives the rotating rod 53 and gear 54 to rotate. The rotation of gear 54 drives rack 56 to move, thereby driving connecting plate 55 and collection plate 57 to move. During the movement of collection plate 57, it continuously contacts guide plate 58, so that the top edge of guide plate 58 scrapes away the water droplets at the bottom of collection plate 57. The scraped water droplets flow into collection box 59 along guide plate 58 to achieve centralized collection of water droplets, improve utilization rate and help save water.

[0027] A circulation assembly 6 is provided on the outer surface of the tower body 1. The circulation assembly 6 includes a second mounting plate 61 fixedly connected to one side of the tower body 1, a water pump 62 fixedly installed on the top of the second mounting plate 61, a first water pipe 63 fixedly connected to the output end of the water pump 62, a spray pipe 64 fixedly connected to one end of the first water pipe 63, a nozzle 65 fixedly connected to the outer surface of the spray pipe 64, a second water pipe 66 fixedly connected to the input end of the water pump 62, and a double-ended pipe 67 fixedly connected to one end of the second water pipe 66. One end of the double-ended pipe 67 is fixedly inserted into the collection box 59. The other end is fixedly inserted into the tower body 1, the first water pipe 63 is fixedly inserted through the tower body 1, the spray pipe 64 is set inside the tower body 1, and the nozzle 65 is set above the coil 2, so that water can be evenly sprayed on the outer surface of the coil 2 to cool the fluid inside the coil 2. The sprayed water flows into the bottom of the tower body 1. Under the action of the water pump 62, the water inside the bottom of the tower body 1 and the collection box 59 enters the spray pipe 64 through the double-ended pipe 67, the second water pipe 66 and the first water pipe 63 in sequence, and is sprayed out again through the nozzle 65, which is convenient for recycling and helps to save water.

[0028] The tower body 1 is equipped with a cooling assembly 4. The cooling assembly 4 includes a second motor 41 fixedly connected to the bottom end of the tower body 1, a threaded rod 42 fixedly connected to the output end of the second motor 41, a first connecting ring 43 threadedly connected to the outer surface of the threaded rod 42, an air inlet box 44 fixedly connected to one end of the first connecting ring 43, an air outlet pipe 45 fixedly connected to one side of the air inlet box 44, a blower 46 and a heating box 47 fixedly installed on one side of the tower body 1, a first connecting pipe 461 fixedly connected between the blower 46 and the heating box 47, a heating pipe 48 fixedly connected inside the heating box 47, and a second connecting pipe 49 fixedly connected between the heating box 47 and the air inlet box 44. The second connecting pipe 49 is movably connected through... A threaded rod 42 rotates through the tower body 1. A first connecting ring 43 is located inside the tower body 1. A second connecting pipe 49 is a telescopic flexible hose. Under the action of a blower 46, gas enters the heating box 47 through the first connecting pipe 461. The heating pipe 48 inside the heating box 47 heats the gas, raising its temperature. The heated gas enters the air inlet box 44 through the second connecting pipe 49 and is finally blown onto the outer surface of the coil 2 through the air outlet pipe 45 to prevent the cooling fluid inside the coil 2 from freezing. The threaded rod 42 is rotated by the second motor 41, which in turn moves the first connecting ring 43 and the air inlet box 44 up and down, expanding the spray range of the air outlet pipe 45 to ensure that all parts of the coil 2 are heated evenly.

[0029] A cover 471 is movably connected to one side of the heating chamber 47, and a filter plate 472 is movably connected inside the heating chamber 47. The filter plate 472 is located below the heating tube 48. The gas entering the heating chamber 47 is first filtered through the filter plate 472 to remove impurities and dust, ensuring that the gas entering the heating chamber 47 is clean and extending the service life of the heating tube 48.

[0030] A slide rod 8 is fixedly connected inside the tower body 1. A second connecting ring 81 is slidably connected to the outer surface of the slide rod 8. The second connecting ring 81 is fixedly connected to the air inlet box 44. When the threaded rod 42 rotates, it drives the first connecting ring 43 to move up and down. As the air inlet box 44 moves up and down, the second connecting ring 81 slides along the outer surface of the slide rod 8, which plays a guiding role.

[0031] The outer surface of the guide plate 58 is provided with a guide groove 581, which facilitates the provision of a clear water flow path, allowing water droplets to slide down the guide plate 58 more quickly.

[0032] In use, the fluid being cooled inside coil 2 flows to carry away heat and achieve cooling. Water droplets accumulate at the bottom of collection plate 57. The first motor 52 drives the rotating rod 53 and gear 54 to rotate. The gear 54 rotates, causing the rack 56 to move, which in turn moves the connecting plate 55 and collection plate 57. During this movement, collection plate 57 continuously contacts guide plate 58, causing the top edge of guide plate 58 to scrape away water droplets from the bottom of collection plate 57. The scraped water droplets flow along guide plate 58 into collection box 59 for concentrated collection. Spray nozzle 65 evenly sprays water onto the outer surface of coil 2 to cool the fluid inside. The sprayed water flows into the bottom of tower body 1. Under the action of water pump 62, the bottom of tower body 1... Water from the end and collection box 59 enters the spray pipe 64 through the double-ended pipe 67, the second water pipe 66, and the first water pipe 63, and is sprayed out again through the nozzle 65 for easy recycling. When the temperature is low, the blower 46 is started. At this time, the gas enters the heating box 47 through the first connecting pipe 461. The heating pipe 48 inside the heating box 47 heats the gas, raising its temperature. The heated gas enters the air inlet box 44 through the second connecting pipe 49, and finally blows onto the outer surface of the coil 2 through the air outlet pipe 45 to prevent the cooling fluid inside the coil 2 from freezing. The second motor 41 drives the threaded rod 42 to rotate, thereby driving the first connecting ring 43 and the air inlet box 44 to move up and down, which expands the spray range of the air outlet pipe 45 to ensure that all parts of the coil 2 are heated evenly and to prevent freezing.
