Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to the structure of a variable diameter spiral cooling tower spray pipe. Background Technology

[0002] A cooling tower is a heat dissipation device that transfers waste heat generated in industrial production or refrigeration and air conditioning into the atmosphere through direct or indirect contact between water and air, thereby lowering the water temperature and allowing the water to be recycled. It is like a giant refrigerator that "cools down" industrial processes or building air conditioning systems, but its cooling target is water, not air. There is usually a problem of directional deviation during the water spraying process, that is, the spray angle needs to be adjusted according to the needs to adapt to different air cooling requirements. However, the existing spray devices for spraying water are all fixed and do not have angle adjustment settings.

[0003] Therefore, we designed a variable diameter spiral cooling tower spray pipe structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the spray angle needs to be adjusted according to the requirements to adapt to different air cooling needs, and proposes a variable diameter spiral cooling tower spray pipe structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The variable diameter spiral cooling tower spray pipe structure includes a cooling tower body, a drive mechanism inside the cooling tower body, an outlet pipe and an inlet pipe on the cooling tower body, and control valves on both the outlet pipe and the inlet pipe. A spraying device is installed inside the cooling tower body, including a spray pipe, which is installed inside the cooling tower body via a mounting base. The spray pipe is connected to the inlet pipe via a water guide pipe. A water spray side pipe is inserted into the spray pipe, and a movable tilting plate for spraying water is installed at the end of the water spray side pipe. Multiple water spray holes are vertically opened on the movable tilting plate.

[0006] Preferably, the spray pipe is provided with a first fan blade and a second fan blade at both ends, and the first fan blade and the second fan blade rotate coaxially at both ends of the spray pipe via a first rotating base and a second rotating base, respectively.

[0007] Preferably, a polygonal platform is fixed to the outer wall of the spray pipe, and a water spraying side pipe is inserted into the side wall of the polygonal platform and communicates with the spray pipe.

[0008] Preferably, one end of the water spray side pipe is vertically provided with an end pipe that communicates with the water spray side pipe, and the end pipe is also provided with a movable pipe. The movable flip plate flips inside the movable pipe through the side rotating shaft, and a rotating gear is coaxially fixed on the side rotating shaft.

[0009] Preferably, the inner wall of the movable tube is provided with a U-shaped side cavity, and a support plate is movable in the side cavity. The two ends of the support plate are provided with racks that mesh with the rotating gear.

[0010] Preferably, a pressure rod is provided on the support plate, and the pressure rod moves coaxially up and down on the end tube by means of a return spring. An impact plate is also provided on the pressure rod.

[0011] The beneficial effects of this utility model are as follows: 1. In this utility model, the impact of water flow on the impact plate can drive the impact plate to descend. The greater the water flow speed, the greater the impact force on the impact plate, and the greater the downward pressure of the pressure rod driven by the impact plate. Therefore, the downward pressure of the pressure rod can be controlled by controlling the water flow speed.

[0012] 2. The greater the downward pressure of the lowering rod of this utility model, the greater the rotation amplitude of the rack and the rotating gear meshing, which in turn drives the movable flip plate to flip. The flip amplitude of the movable flip plate is controlled by the water flow speed, and finally the spray angle of the water body is controlled, thereby controlling the degree of air cooling. The greater the angle of inclination of the spray with respect to the horizontal plane, the longer the contact time between the water body and the air, and the better the air cooling effect.

[0015] Reference Figures 1-6 The variable diameter spiral cooling tower spray pipe structure includes a cooling tower body 1, a drive mechanism is installed inside the cooling tower body 1, and a water outlet pipe 2 and a water inlet pipe 3 are installed on the cooling tower body 1. Both the water outlet pipe 2 and the water inlet pipe 3 are equipped with control valves 4. The water inlet pipe 3 is used to introduce water to be cooled into the cooling tower body 1. The cooled water is discharged from the water outlet pipe 2. The flow rate of the water discharged from the water outlet pipe 2 is adjusted according to the water temperature by the control valves 4. The control valves 4 are existing technology and will not be described in detail here.

[0016] The cooling tower body 1 is equipped with a spraying device, which includes a spray pipe 6. The spray pipe 6 is connected to the water inlet pipe 3 through a water guide pipe 5. In this way, the water entering from the water inlet pipe 3 will first enter the spray pipe 6. A water spray side pipe 13 is inserted on the spray pipe 6, and then it will be discharged from the water spray side pipe 13, thus completing the spraying operation of the water.

[0017] The spray pipe 6 is provided with a first fan blade 7 and a second fan blade 8 at both ends. The first fan blade 7 and the second fan blade 8 rotate coaxially at both ends of the spray pipe 6 via a first rotating base 9 and a second rotating base 10, respectively. The first fan blade 7 and the second fan blade 8 are driven by a driving mechanism, which in turn drives the first fan blade 7 and the second fan blade 8 to rotate, thereby completing the air cooling operation of the water.

[0018] The spray pipe 6 is installed inside the cooling tower body 1 via the mounting base 11. A polygonal platform 12 is fixed to the outer wall of the spray pipe 6. The water spray side pipe 13 is inserted into the side wall of the polygonal platform 12 and communicates with the spray pipe 6, so water enters the water spray side pipe 13 from the spray pipe 6. One end of the water spray side pipe 13 is vertically provided with an end pipe 14 communicating with the water spray side pipe 13, and a movable pipe 15 is also provided on the end pipe 14. The movable flip plate 16 flips inside the movable pipe 15 via the side rotating shaft 21. The end of the water spray side pipe 13 is provided with a movable flip plate 16 for spraying water. Multiple water spray holes 20 are vertically opened on the movable flip plate 16, so that the movable flip plate 16 can be flipped inside the movable pipe 15, thereby adjusting the swing angle of the movable flip plate 16. Figure 3 In the state where the spray pipe 6 rotates, it can also rotate the polygonal platform 12 and the water spray side pipe 13 on the side wall together, and the water sprayed from the water spray side pipe 13 will also be sprayed out along with the rotation.

[0019] A downward pressure rod 19 is provided on the support plate 25. The downward pressure rod 19 is raised and lowered coaxially on the end tube 14 by a return spring 18. An impact plate 17 is also provided on the downward pressure rod 19. Therefore, when the water flow impacts the impact plate 17, it can drive the impact plate 17 to descend. The greater the water flow speed, the greater the impact force on the impact plate 17, and the greater the downward pressure of the downward pressure rod 19 driven by the impact plate 17. Therefore, the downward pressure of the downward pressure rod 19 can be controlled by controlling the water flow speed.

[0020] A rotating gear 22 is coaxially fixed on the side rotating shaft 21. The inner wall of the movable tube 15 is provided with a U-shaped side cavity 24, and a support plate 25 is movable in the side cavity 24. The two ends of the support plate 25 are provided with racks 23 that mesh with the rotating gear 22. It should be noted that the greater the downward pressure of the pressing rod 19, the greater the rotation amplitude of the rack 23 meshing with the rotating gear 22, which in turn drives the movable flip plate 16 to flip. The flip amplitude of the movable flip plate 16 is controlled by the water flow rate, which ultimately controls the spray angle of the water and thus the degree of air cooling. The greater the angle of inclination of the spray with respect to the horizontal plane, the longer the contact time between the water and the air, and the better the air cooling effect.

[0021] The working principle of this utility model is as follows: The inlet pipe 3 is used to introduce water to be cooled into the cooling tower body 1. After being cooled, the water is discharged from the outlet pipe 2. The flow rate of the water discharged from the outlet pipe 2 is adjusted according to the water temperature by the control valve 4. Then, the rotation amplitude of the movable tilting plate 16 is controlled by controlling the water flow rate, and finally the spray angle of the water is controlled, thereby controlling the degree of air cooling. The larger the angle of the spray with respect to the horizontal plane, the longer the contact time between the water and the air, and the better the air cooling effect.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
