Description

Technical Field

[0001] The utility model relates to the field of cooling towers, and specifically to a water-saving closed cooling tower. Background Art

[0002] A closed cooling tower places a tube heat exchanger inside the tower. Through the heat exchange of the flowing air, the water sprayed outside the tubes and the circulating water inside the tubes, the cooling effect is ensured. Since the circulating water is in a closed loop inside the tubes, 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 spray water system can be stopped to achieve water-saving effects. With the implementation of the country's energy conservation and emission reduction policies and the increasing scarcity of water resources, in recent years, closed cooling towers have been widely used in industries such as iron and steel metallurgy, power electronics, machining, and air conditioning systems.

Most water-saving closed cooling towers generally directly discharge the water vapor outside the cooling tower. However, this method will cause some water to be directly dissipated into the air, easily losing some water, with poor water collection performance, resulting in a certain amount of resource waste. And most of the nozzles of water-saving closed cooling towers are fixedly installed, and it may be impossible to spray the pipelines at the corners, reducing the working efficiency of the cooling tower.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments 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 making creative efforts belong to the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4 As shown in the figure, this embodiment provides a water-saving closed cooling tower, including a cooling tower body 1 and a water storage tank 2. The water storage tank 2 is placed on one side of the cooling tower body 1. A first filter plate 3 is fixedly connected to the inner wall of the cooling tower body 1. By setting the first filter plate 3, when water vapor passes through the first filter plate 3, the first filter plate 3 will separate the water vapor. The water droplets will fall to the bottom of the tower under the action of gravity, and some will also gather below the first filter plate 3. An auxiliary mechanism 4 is rotatably connected to the inner wall of the cooling tower body 1, which is used to scrape off the water gathered below the first filter plate 3, facilitating the rapid collection of water droplets. A cooling mechanism 5 for cold treatment of hot water is fixedly connected to the inner wall of the cooling tower body 1. A rotating mechanism 6 is rotatably connected to the inner wall of the cooling tower body 1, which is used to drive the cooling mechanism 5 to rotate, improving the spraying range of the device.

[0022] The improvement of this embodiment lies in:

[0023] When the cooling tower cools down the hot water, a large amount of water vapor will be generated. Most water-saving closed cooling towers generally discharge the water vapor directly outside the cooling tower. However, this method will cause some water to be directly dissipated into the air, resulting in the loss of some water and poor water collection performance, causing certain resource waste. Moreover, the nozzles of most water-saving closed cooling towers are fixedly installed, and it may be impossible to spray the pipes at the corners, reducing the working efficiency of the cooling tower. Therefore, an auxiliary mechanism 4 is provided to scrape off the water droplets gathered under the first filter plate 3, facilitating the rapid collection of water droplets, making the device have better water-saving and environmental protection effects, thus reducing the loss of cooling water. And a cooling mechanism 5 and a rotating mechanism 6 are provided to drive the cooling mechanism 5 to rotate, making the spraying range of the device wider and improving the cooling effect of the device.

[0024] Considering the need to quickly collect the water droplets gathered under the first filter plate 3, the structure of the auxiliary mechanism 4 is further disclosed as follows Figure 3 and Figure 4 As shown, the auxiliary mechanism 4 includes a reciprocating screw rod 41 rotatably connected to the inner wall of the cooling tower body 1, and one side of the reciprocating screw rod 41 penetrates through the cooling tower body 1. A driving motor 42 is fixedly installed on the side of the reciprocating screw rod 41 penetrating through the cooling tower body 1. Starting the driving motor 42 drives the reciprocating screw rod 41 to rotate. A slider 43 is screwed on the reciprocating screw rod 41. When the reciprocating screw rod 41 rotates, it drives the slider 43 to move. The top of the slider 43 is fixedly connected with a scraping rod 44, and the top of the scraping rod 44 is in contact with the bottom of the first filter plate 3. The movement of the slider 43 drives the scraping rod 44 to move, scraping off the water droplets under the first filter plate 3 and realizing the rapid collection of water droplets.

[0025] Considering the need to cool down the hot water entering the cooling tower body 1, the structure of the cooling mechanism 5 is further disclosed as follows Figure 3 and Figure 4 As shown, the cooling mechanism 5 includes a fixed rod 51 fixedly connected to the inner wall of the cooling tower body 1. The bottom of the fixed rod 51 is rotatably connected with a cross rod 52. A plurality of spray nozzles 53 are installed at the bottom of the cross rod 52. When the cross rod 52 rotates, it drives the spray nozzles 53 to rotate and spray. Cavities are opened inside both the fixed rod 51 and the cross rod 52. A first water pump 54 is fixedly installed on the top of the water storage tank 2. One side of the first water pump 54 is communicated with the water storage tank 2, and the other side of the first water pump 54 penetrates through the cooling tower body 1 and is connected to the fixed rod 51. Starting the first water pump 54 pumps the cooling water inside the water storage tank 2 into the cavities inside the fixed rod 51 and the cross rod 52, and then sprays it out from the spray nozzles 53 to cool down the hot water entering the cooling tower body 1.

[0026] Considering the need to drive the spray nozzles 53 to rotate, the structure of the rotating mechanism 6 is further disclosed as follows Figure 4As shown in the figure, the rotating mechanism 6 includes a worm 61 rotatably connected to the inner wall of the cooling tower body 1, and one side of the worm 61 penetrates through the cooling tower body 1. A belt 62 is sleeved on one side of the reciprocating screw rod 41 passing through the cooling tower body 1, and the belt 62 is sleeved on the side of the worm 61 penetrating through the cooling tower body 1 away from the reciprocating screw rod 41. When the driving motor 42 rotates, it drives the worm 61 to rotate in cooperation with the belt 62. A worm gear 63 is fixedly connected to the outer wall of the cross rod 52, and the worm gear 63 is meshed with the worm 61. When the worm 61 rotates, it drives the worm gear 63 to rotate, thereby driving the cross rod 52 and the spray head 53 in the cooling mechanism 5 to rotate, making the spraying range wider and improving the cooling effect of the device.

[0027] Considering that the sprayed water needs to be collected and reused, a water collecting tank 8 is fixedly connected to the inner bottom of the cooling tower body 1. A second filter plate 9 is fixedly connected to the inner wall of the water collecting tank 8. The sprayed water falls above the second filter plate 9, is filtered by the second filter plate 9, and then falls into the water collecting tank 8. A second water pump 10 is placed between the cooling tower body 1 and the water storage tank 2. One side of the second water pump 10 is communicated with the water storage tank 2, and the other side of the second water pump 10 penetrates through the cooling tower body 1 and is connected to the water collecting tank 8. Starting the second water pump 10 pumps the water in the water collecting tank 8 into the water storage tank 2 for recycling, achieving the effect of water saving and environmental protection.

[0028] In order to draw the air outside the cooling tower body 1 into the cooling tower body 1, an air outlet is opened at the top of the cooling tower body 1.

Hot water is introduced into the water pipe 13 to realize the cooling treatment of the hot water.

[0029] In order to scrape off the water droplets on the surface of the fixed rod 51, a connecting rod 11 is fixedly connected below the scraping rod 44, and the bottom of the connecting rod 11 is attached to the top of the fixed rod 51. When the scraping rod 44 moves, it can drive the connecting rod 11 to move and scrape off the water droplets on the top of the fixed rod 51, improving the use effect of the device. A protective box 12 is fixedly connected to the outer wall of the fixed rod 51. The protective box 12 is sleeved outside the worm 61 and the worm gear 63, and the protective box 12 is rotatably connected to the worm 61, preventing water droplets from falling into the teeth of the worm 61 and the worm gear 63 and polluting the water droplets.

[0030] When the water-saving closed cooling tower of the utility model is specifically used, first start the fan 7 to draw the air outside the cooling tower body 1 into the cooling tower body 1 through the air inlet. Then start the first water pump 54 to draw the cooling water inside the water storage tank 2 into the fixed rod 51 and the cross rod 52, and then spray it out from the spray head 53 to cool the hot water inside the water pipe 13. At this time, the evaporated water vapor passes through the first filter plate 3 under the suction of the fan 7. The first filter plate 3 separates the water vapor. The water droplets fall to the bottom of the tower under the action of gravity, and some will also gather under the first filter plate 3;

[0031] Then start the driving motor 42 to drive the reciprocating screw rod 41 to rotate, so as to drive the slider 43 to linearly move on the reciprocating screw rod 41, and then drive the scraping rod 44 to scrape off the water droplets under the first filter plate 3. When the driving motor 42 rotates, it cooperates with the belt 62 to drive the worm 61 to rotate, so as to drive the worm gear 63 to rotate, and then drive the cross rod 52 to rotate. The rotation of the cross rod 52 drives the spray head 53 to rotate and spray, spraying more comprehensively to the corners of the water pipe 13, improving the cooling effect of the device.
