Description

Technical Field

[0001] This utility model relates to the field of counterflow cooling tower technology, specifically to a novel counterflow all-steel cooling tower. Background Technology

[0002] A counter-flow cooling tower is a cooling device that lowers water temperature by exchanging heat between air and water. It works by having water flow vertically down inside the tower, with the airflow direction opposite to the water flow direction. The water exchanges heat and mass with the flowing air inside, causing the water temperature to drop.

[0003] A search revealed that patent document CN207850118U discloses a counter-flow cooling tower. In this cooling tower, when the circulating water flows through the packing, the rotation of the packing causes the circulating water to adhere to the packing wall, which prolongs the time that the circulating water stays in the packing and improves the cooling effect.

[0004] However, the air volume provided by the bottom fan of the above-mentioned cooling tower is fixed when in use. When the water flow rate discharged from the nozzle is large, the cooling air blown out by the fan cannot fully exchange heat and cool the water, thus reducing the cooling effect. Summary of the Invention

[0005] In view of the problems existing in the current counter-flow all-steel cooling tower, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a new type of counter-flow all-steel cooling tower, which solves the problem that the air volume of the bottom fan of the existing cooling tower is fixed and cannot be adjusted according to the amount of water sprayed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel counter-flow all-steel cooling tower includes an all-steel tower body and an exhaust pipe located at the top of the all-steel tower body. A water pipe is fixedly installed on the side of the all-steel tower body, and a nozzle is connected to the opening of the water pipe. Packing material is fixedly installed on the upper end of the inner wall of the all-steel tower body. A main fan is fixedly installed at the center of the bottom of the all-steel tower body, and auxiliary fans are fixedly embedded at the bottom of the all-steel tower body on both sides of the main fan.

[0009] The main fan and the auxiliary fan are respectively equipped with a main shaft and an auxiliary shaft inside, and a connecting transmission mechanism is provided between the main shaft and the auxiliary shaft;

[0010] The upper end of the inner wall of the all-steel tower body is provided with a starting mechanism, and the lower end of the outer wall of the all-steel tower body is fixedly provided with a PLC controller. The PLC controller is electrically connected to the starting mechanism and the connecting transmission mechanism.

[0011] Preferably, the connecting transmission mechanism includes a vertical plate, which is fixedly disposed at the bottom of the all-steel tower body and has a support cylinder fixedly disposed inside it. A fixed electromagnetic ring is fixedly disposed on the inner side wall of the support cylinder, and a movable electromagnetic ring is slidably disposed on the inner wall of the support cylinder. A transmission shaft is rotatably disposed inside the movable electromagnetic ring, and the shaft wall of the transmission shaft is slidably disposed on the side of the support cylinder. A first driving bevel gear and a first transmission bevel gear are fixedly disposed at one end of the transmission shaft and the auxiliary shaft respectively. An installation plate is fixedly disposed at the bottom of the main fan, and a rotating rod is rotatably disposed inside the installation plate. A telescopic rod is fixedly disposed between the rotating rod and the transmission shaft. A second driving bevel gear and a second transmission bevel gear are fixedly disposed at one end of the rotating rod and the main shaft respectively. The second driving bevel gear and the second transmission bevel gear are configured to cooperate with each other.

[0012] Preferably, the telescopic rod is a square telescopic rod.

[0013] Preferably, the support cylinder has two symmetrically arranged strip holes on its side, and a sliding plate slides through the strip holes. The sliding plate is fixedly connected to the movable electromagnetic ring.

[0014] Furthermore, the starting mechanism includes an impeller, a support rod is fixedly provided on the upper side of the inner wall of the all-steel tower body, the impeller is rotatably sleeved on the outside of the support rod, a detection ring is fixedly provided on the outer wall of the impeller, a speed sensor is fixedly sleeved on the outer wall of the support rod, and the detection ring is sleeved on the outside of the speed sensor.

[0015] Preferably, the movable electromagnetic ring is rotatably engaged with the shaft wall of the transmission shaft via its internal bearing.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] This utility model, through its all-steel tower body, nozzles, main fan, auxiliary fan, connecting transmission mechanism, and starting mechanism, can drive both auxiliary fans to start simultaneously when the water volume is large, thus cooperating with the main fan to quickly exchange heat with the water and improve the cooling effect of the cooling tower. At the same time, it can operate with only the main fan when the water volume is small, reducing excessive resource consumption.

[0018] This invention, through its set start-up mechanism, nozzle, and PLC controller, can accurately detect the water spray volume of the nozzle, thereby controlling the main and auxiliary fans to work in tandem. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a novel counter-flow all-steel cooling tower.

[0028] This utility model provides, for example Figure 1-4 The novel counter-flow all-steel cooling tower shown includes an all-steel tower body 1 and an exhaust pipe 2 located at the top of the all-steel tower body 1. A water pipe 3 is fixedly installed on the side of the all-steel tower body 1, and a nozzle 4 is connected to the pipe opening of the water pipe 3. A packing 5 is fixedly installed on the upper end of the inner wall of the all-steel tower body 1. A main fan 6 is fixedly installed at the center of the bottom of the all-steel tower body 1. Auxiliary fans 7 are fixedly embedded at the bottom of the all-steel tower body 1 and on both sides of the main fan 6.

[0029] The main fan 6 and the auxiliary fan 7 are respectively equipped with a main shaft 8 and an auxiliary shaft 9, and a connecting transmission mechanism is provided between the main shaft 8 and the auxiliary shaft 9;

[0030] The upper end of the inner wall of the all-steel tower body 1 is provided with a starting mechanism, and the lower end of the outer wall of the all-steel tower body 1 is fixedly provided with a PLC controller 10. The PLC controller 10 is electrically connected to the starting mechanism and the connecting transmission mechanism.

[0031] When the cooling tower is in use, the water pipe 3 is connected to an external water pump or other water pumping equipment, so that the water is sprayed out through the nozzle 4. Then the main fan 6 starts to blow air into the tower, so that the cooling airflow comes into contact with the water to complete the heat exchange and cooling. When the amount of water sprayed out of the nozzle 4 increases, the starting mechanism runs, and in conjunction with the PLC controller 10, the auxiliary fans 7 on both sides start to increase the air volume and improve the heat exchange efficiency.

[0032] In order to enable the auxiliary fan 7 to start and cooperate with the main fan 6 to supply air when the water volume increases, such as Figure 2-4 As shown, the starting mechanism includes an impeller 24, a support rod 25 is fixedly installed on the upper side of the inner wall of the all-steel tower body 1, the impeller 24 is rotatably sleeved on the outside of the support rod 25, a detection ring 26 is fixedly installed on the outer wall of the impeller 24, a speed sensor 27 is fixedly sleeved on the outer wall of the support rod 25, and the detection ring 26 is sleeved on the outside of the speed sensor 27.

[0033] The connecting transmission mechanism includes a vertical plate 11, which is fixedly installed at the bottom of the all-steel tower body 1. A support cylinder 12 is fixedly installed inside the vertical plate 11. A fixed electromagnetic ring 13 is fixedly installed on the inner wall of the support cylinder 12. A movable electromagnetic ring 14 slides through the inner wall of the support cylinder 12. Two symmetrically arranged strip holes are opened on the side of the support cylinder 12. A sliding plate 23 slides through the strip holes and is fixedly connected to the movable electromagnetic ring 14. A transmission shaft 15 is rotatably installed inside the movable electromagnetic ring 14. The movable electromagnetic ring 14 rotates with the shaft wall of the transmission shaft 15 through its internal bearing. The shaft wall of 15 slides through the side of the support cylinder 12. The first drive bevel gear 16 and the first transmission bevel gear 17 are fixedly installed at the close ends of the drive shaft 15 and the auxiliary shaft 9, respectively. The bottom of the main fan 6 is fixedly provided with a mounting plate 18. A rotating rod 19 is rotatably installed inside the mounting plate 18. A telescopic rod 20 is fixed between the rotating rod 19 and the drive shaft 15. The telescopic rod 20 is a square telescopic rod. The second drive bevel gear 21 and the second transmission bevel gear 22 are fixedly installed at the close ends of the rotating rod 19 and the main shaft 8, respectively. The second drive bevel gear 21 and the second transmission bevel gear 22 are configured to cooperate with each other.

[0034] When the water volume increases, the velocity of the water sprayed from inside the nozzle 4 increases, thereby increasing the thrust of the water on the impeller 24. This causes the impeller 24 to rotate rapidly around the support rod 25. At this time, the speed sensor 27 monitors the speed of the detection ring 26. The speed sensor 27 can be a magnetoelectric speed sensor. When the detected speed increases, the internal resistance of the sensor decreases, which is existing technology and will not be elaborated further. This increases the current of the fixed electromagnetic ring 13 connected in the same circuit, thereby improving the current between the moving electromagnetic ring 14 and the fixed electromagnetic ring 13. The magnetic field strength causes the movable electromagnetic ring 14 to move laterally, which in turn drives the transmission shaft 15 away from the fixed electromagnetic ring 13. At this time, the first drive bevel gear 16 and the second transmission bevel gear 17 mesh. As the main fan 6 is running, its internal main shaft 8 rotates. Under the meshing of the second drive bevel gear 21 and the second transmission bevel gear 22, the rotating rod 19 rotates. Thus, under the connection of the telescopic rod 20, the transmission shaft 15 rotates stably and drives the auxiliary shaft 9 to rotate, thereby driving the auxiliary fan 7 to run and cooperate with the main fan 6 to increase the air volume and improve the heat exchange and cooling effect on the water.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
