The core function of the centrifugal forced cross-flow cooling tower is to cool the circulating water carrying heat.

[0003] Hot water is sprayed evenly from the water distribution system on the upper part of the tower body to the packing components to form a water film. The centrifugal blower inhales outside air from the side of the tower body, and the air passes through the packing horizontally to fully exchange heat with the water film. In this process, the heat of the hot water is transferred to the air, and the heated air is discharged from the other side of the tower body. The cooled water is collected in the water collection tank at the bottom of the tower body, and then transported to the equipment or system to be cooled to achieve circulating cooling.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 9 As shown, the present invention provides an embodiment: a secondary temperature control device for a centrifugal blast cross-flow cooling tower, comprising a tower body 1, a water collecting seat 2 is fixedly connected to the bottom of the tower body 1, and further comprising: The air supply assembly 3 is located at the top of the tower body 1 and is used to draw outside air into the tower body 1; The adjusting assembly 5 is symmetrically arranged inside the tower body 1. The adjusting assembly 5 includes a clamping sleeve 51 and a movable plate 52. The number of the clamping sleeve 51 and the movable plate 52 is set to be several. The movable plate 52 is slidably connected to the inside of the clamping sleeve 51. The clamping sleeve 51 is rotatably connected to the inside of the tower body 1 through the installation shaft 57. The outer side walls of several clamping sleeves 51 are symmetrically rotatably connected to the connecting seats 55. The two connecting seats 55 are fixedly connected to the side away from each other with a connecting block 56. The outer side wall of the connecting block 56 is rotatably connected to a push rod 53. The outer side wall of the push rod 53 is rotatably connected to a slider 54. The inner wall of the tower body 1 is symmetrically provided with sliding grooves, the connecting seat 55 is slidably connected in the sliding grooves, the connecting block 56 passes through the sliding grooves and is fixedly connected to the connecting seat 55, and the outer side of the movable plate 52 is symmetrically fixedly connected to the limit strip 58; The transmission component 4 is arranged at the top of the tower body 1, so that the air supply component 3 controls the regulating component 5 through the transmission component 4 to adjust the air intake; The water distribution assembly 6 is symmetrically arranged inside the tower body 1 to increase the contact area between cooling water and air.

[0022] In practical application, the embodiment of the present invention is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, first, the air supply component 3 is started to draw outside air into the tower body 1. When the cooling tower needs to be temperature-adjusted for the second time, the transmission component 4 drives the push rod 53 to move under the drive of the air supply component 3. The slider 54 at one end of the push rod 53 moves under a specific motion trajectory. Since the push rod 53 is rotatably connected with the connecting block 56, the connecting block 56 is fixed to the connecting seat 55 and the connecting seat 55 slides in the slide groove of the inner wall of the tower body 1. This linkage makes the connecting seat 55 slide in the slide groove with the movement of the push rod 53. The sliding of the connecting seat 55 further drives the ferrule 51 to rotate around the mounting shaft 57. The movable plate 52 in the ferrule 51 slides relative to the ferrule 51 under the restriction of the limit bar 58, thereby changing the overall state of the adjustment component 5 and realizing the adjustment of the air intake amount. At the same time, Figure 2 and Figure 3 As shown, the water distribution component 6 evenly distributes the cooling water inside the tower body 1, so that the cooling water forms a suitable water film or water droplets. By adjusting the air intake, the heat exchange efficiency between the air and the cooling water is changed. When the air intake increases, more cold air enters the tower body 1 and fully contacts with the cooling water, which can enhance the cooling effect and reduce the water temperature more quickly, meeting the need for rapid cooling when the cooling water temperature is high; on the contrary, when the air intake decreases, the degree of heat exchange decreases, and the temperature drop of the cooling water decreases, which is suitable for situations where the cooling water temperature is close to the target temperature or needs to be maintained within a certain temperature range. In this way, secondary temperature adjustment of the centrifugal forced draft cross-flow cooling tower is achieved, ensuring that the cooling water temperature can accurately meet the cooling water temperature requirements of different industrial equipment, improving the temperature control accuracy and cooling efficiency of the entire cooling tower, and ensuring the stable operation of equipment in industrial production.

[0023] like Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the air supply component 3 includes a mounting base 31 fixedly connected to the inside of the tower body 1, a support frame 34 is symmetrically fixedly connected inside the mounting base 31, a mounting plate 35 is symmetrically fixedly connected between the two support frames 34, a motor 32 is fixedly connected to the lower surface of the mounting plate 35 at the bottom, the insides of the two mounting plates 35 are both rotatably connected to a connecting shaft 36, the top of the connecting shaft 36 is fixedly connected to a fan blade 33, the air supply component 3 also includes a guide plate 39 symmetrically fixedly connected to the outside of the connecting shaft 36, a push block 37 is symmetrically slidably connected inside the connecting shaft 36, and a spring 38 is fixedly connected between the two push blocks 37.

[0024] In actual application of the embodiment of the present invention, the motor 32 is started, driving the connecting shaft 36 connected thereto to rotate, and the connecting shaft 36 further drives the fan blades 33 at the top to rotate. The rotation of the fan blades 33 causes the outside air to be drawn into the tower body 1, providing the necessary airflow conditions for the heat exchange process in the cooling tower; During the rotation of the connecting shaft 36, the guide plate 39 fixed on the outside thereof also rotates accordingly. At the same time, the push block 37 slidably connected inside the connecting shaft 36 is displaced under the action of centrifugal force. Since a spring 38 is connected between the two push blocks 37, the elastic force of the spring 38 interacts with the centrifugal force, so that the push block 37 is in a specific position in the connecting shaft 36, so that the position state of the push block 37 can be changed according to the change in the speed of the connecting shaft 36, that is, the change in the speed of the motor 32, so as to control the adjustment component 5 through the transmission component 4 to realize the adjustment of the air intake volume, provide reliable air supply for the stable operation of the cooling tower, ensure that the air and cooling water are fully and efficiently exchanged with each other in the tower body 1, and improve the overall performance of the cooling tower.

[0025] like Figures 3 to 6 As shown, the transmission assembly 4 includes a mounting frame 41 symmetrically fixedly connected to the top of the tower body 1, a bidirectional screw rod 42 is symmetrically rotatably connected between the two mounting frames 41, a screw pair transmission is formed between the sliders 54 and the bidirectional screw rod 42, a gear 43 is fixedly connected to the outer side of the bidirectional screw rod 42, a rack 44 is slidably connected to the inside of the support frame 34, the gear 43 and the rack 44 are meshed with each other, a protrusion 45 and a limit block 47 are symmetrically fixedly connected to the outer side of the rack 44, a spring 2 46 is fixedly connected between the protrusion 45 and the inner wall of the support frame 34, a plurality of annular grooves are opened on the side of the guide plate 39 close to the rack 44, and the plurality of annular grooves are connected by transverse grooves, and the limit blocks 47 are slidably connected in the annular grooves and the transverse grooves.

[0026] In actual application, as the guide plate 39 rotates, the position of the limit block 47 slidably connected in the annular groove and the transverse groove thereof changes accordingly. Since the limit block 47 is connected to the rack 44, and the rack 44 is meshed with the gear 43, and the gear 43 is fixed on the bidirectional screw rod 42, when the position of the limit block 47 changes, the position of the rack 44 in the support frame 34 will also change. Under the action of the spring 46 and the protrusion 45, the movement of the rack 44 is more stable and has a certain elastic buffer, and the movement of the rack 44 drives the gear 43 to rotate. The two-way screw rod 42 rotates, and the spiral pair transmission between the two-way screw rod 42 and the slider 54 starts to work. Since the slider 54 is connected to the push rod 53, the push rod 53 is associated with the connecting block 56, the connecting seat 55, the ferrule 51 and the movable plate 52 in the adjusting component 5, thereby realizing the control of the adjusting component 5 by the air supply component 3, so as to adjust the adjusting component 5 according to the working state of the air supply component 3, change the air intake amount, and meet the cooling tower under different working conditions, to ensure that the heat exchange efficiency between cooling water and air reaches the best state.

[0027] like Figure 2 and Figure 3 As shown, the water distribution assembly 6 includes a water tank 61 symmetrically fixedly connected to the inside of the tower body 1, the bottom of the water tank 61 is evenly connected with a nozzle 66, the top of the tower body 1 is fixedly connected with a water inlet pipe connected to the water tank 61, a plurality of fillers 62 are arranged between the water tank 61 and the water collecting seat 2, the fillers 62 are connected by a plurality of heat exchange coils 63, a water baffle 64 is fixedly connected between the water tank 61 and the water collecting seat 2, and a splash plate 65 is evenly fixedly connected to the inside of the tower body 1.

[0028] In actual application, the cooling water enters the water tank 61 from the water inlet pipe at the top of the tower body 1, and then is sprayed out through the nozzles 66 evenly distributed at the bottom of the water tank 61. The nozzles 66 can evenly sprinkle the cooling water downward, ensuring that the cooling water forms a uniform water film or water droplets on the filler 62. A plurality of fillers 62 are distributed between the water tank 61 and the water collecting seat 2, increasing the contact area and contact time between the cooling water and the air, and the heat exchange coils 63 connected between the fillers 62 further improve the heat exchange efficiency. When the air flows in the cooling tower, it will fully contact the cooling water on the fillers 62 and the heat exchange coils 63, and the heat of the cooling water is transferred to the air to achieve cooling. Among them, the water baffle 64 can effectively block the water vapor or small water droplets generated during the cooling process, preventing them from flowing out of the cooling tower with the air, thereby reducing the loss of cooling water. The splash guard 65 can prevent excessive splashing of cooling water due to impact during spraying and falling, thereby ensuring the normal flow of cooling water and heat exchange process in the tower.
