Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and more specifically, to a water-saving cooling tower spray structure with a spiral baffle. Background Technology

[0002] The production of flame retardant masterbatch for thin films typically involves processes such as high-temperature extrusion and granulation. During these processes, a large amount of cooling water is required to rapidly cool the equipment (such as twin-screw extruders and pelletizers) and the products. A closed-loop cooling tower is used to employ a closed circulation system, which reduces evaporation loss through air-water heat exchange and avoids water pollution. This system is suitable for the production of flame retardant masterbatch with high water quality requirements.

[0003] In actual use, during the spraying of cooling water in a closed-circuit cooling tower, the direction of the cooling water spray is relatively fixed. During the long-term spraying process, the contact area between the cooling water and the cooling pipe is fixed, which will reduce the cooling efficiency of the cooling water on the hot water in the cooling pipe. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-saving cooling tower spray structure with spiral baffles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water-saving cooling tower spray structure with spiral baffles includes a tower body, with multiple fixed brackets fixedly connected to the inner side of the tower body. An inlet pipe and an outlet pipe are fixedly connected to one side of the tower body, with a cooling pipe fixedly connected to one end of each pipe. Three air outlet pipes are fixedly connected to the top of the tower body, with a fan installed on the top of each outlet pipe. A water supply pipe is connected to one side of the tower body, with a water pump fixedly connected to the outside of the water supply pipe. A water pipe is fixedly connected to one end of the water supply pipe. A swing spraying mechanism is installed inside the tower body. A cooling mechanism is also installed inside the tower body.

[0007] By adopting the above technical solution: using the air outlet pipe and fan to maintain airflow inside the tower, and using the water supply pipe and water pump to transport cooling water inside the tower.

[0008] As a further description of the above technical solution: the oscillating spraying mechanism includes multiple water supply pipes II, one end of each water supply pipe II is connected to one side of a water pipe, the outer side of each water supply pipe II is fixedly connected to the inner side of multiple fixed brackets, multiple connecting pipes are fixedly connected to the bottom of each water supply pipe II, a flexible hose is fixedly connected to the bottom of each connecting pipe, a water mist nozzle is fixedly connected to the bottom of the flexible hose, and two first fixed rods are fixedly connected to the top of each water mist nozzle. The outer side of each first fixed rod is hinged to the bottom of the water supply pipe II, and multiple connecting rods are fixedly connected to the outer side of each first fixed rod. A connecting rod is rotatably connected to a turntable at one end. A rotating shaft is fixedly connected to one side of the turntable. The outer side of the rotating shaft is rotatably connected to the inner side of the tower body. One end of the rotating shaft passes through the inner side of the tower body and extends to the outer side of the tower body. A gear one is fixedly connected to one end of the rotating shaft. A servo motor is fixedly connected to the outer side of the tower body. A gear two is fixedly connected to the output end of the servo motor. A crossbar is fixedly connected to one side of the tower body. A sliding frame is slidably connected to the outer side of the crossbar. A toothed groove is provided at the top of the sliding frame. A protruding tooth is provided at the bottom of the sliding frame. The inner side of the toothed groove meshes with the outer side of the gear two.

[0009] By adopting the above technical solution: using a servo motor and gear two to reciprocate the sliding frame, and then using three gears one, a rotating shaft and a turntable to reciprocate the three sets of connecting rods, so that multiple water mist nozzles can spray the water inside the water supply pipe two reciprocally inside the tower.

[0010] As a further description of the above technical solution: the cooling mechanism includes a second fixed rod, the outer side of the second fixed rod is fixedly connected to the inner side of the tower body, a spiral baffle is fixedly connected to the outer side of the second fixed rod, the outer side of the spiral baffle is fixedly connected to the inner wall of the tower body, and multiple slots are opened on the inner side of the spiral baffle.

[0011] By adopting the above technical solution, the contact area between the sprayed water and the spiral baffle and the water is increased by using spiral baffles and slots, avoiding the water from falling directly and improving the cooling efficiency of the water flow.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up an oscillating spraying mechanism, compared with the existing technology, the reciprocating transmission of multiple water mist nozzles is achieved by using a servo motor and gears, and by using the bending of the hose for delivery. This allows the three water mist nozzles to keep oscillating synchronously, so that the water is sprayed back and forth on the inside of the tower as the water mist nozzles oscillate. This improves the uniformity of water flow spraying inside the tower and ensures that all areas of the tower are evenly wetted.

[0014] 2. By setting up a cooling mechanism, compared with the existing technology, the spiral arrangement of the spiral baffle and the multiple slots on its surface increase the contact time between water and the surface of the spiral baffle, enhance the adhesion of the water film, prevent the water from falling directly, and improve the heat exchange efficiency of the water flow to the cooling pipe and the spiral baffle.

[0024] The embodiments disclosed in this application are as follows: Figure 1-7The water-saving cooling tower spray structure with spiral baffles shown includes a tower body 1. Multiple fixed brackets 2 are fixedly connected to the inner side of the tower body 1. A water inlet pipe 3 and a water outlet pipe 5 are fixedly connected to one side of the tower body 1.

A fan 7 is installed on the top of the air outlet pipes 6. A water supply pipe 8 is connected to one side of the tower body 1. A water pump 9 is fixedly connected to the outside of the water supply pipe 8. A water pipe 10 is fixedly connected to one end of the water supply pipe 8. An oscillating spraying mechanism is provided inside the tower body 1. A cooling mechanism is provided inside the tower body 1. The air inside the tower body 1 is output to the outside using the three air outlet pipes 6 and the fan 7, and the cooling water at the bottom of the tower body 1 is transported through the water pump 9 and the water supply pipe 8.

[0025] Reference Figure 3 , Figure 5 and Figure 6 As shown, the oscillating spraying mechanism includes multiple water supply pipes 11. One end of each water supply pipe 11 is connected to one side of a water pipe 10. The outer side of each water supply pipe 11 is fixedly connected to the inner side of multiple fixed brackets 2. Multiple connecting pipes 12 are fixedly connected to the bottom of each water supply pipe 11. A flexible hose 13 is fixedly connected to the bottom of each connecting pipe 12. A water mist nozzle 14 is fixedly connected to the bottom of each flexible hose 13. Two first fixed rods 15 are fixedly connected to the top of each water mist nozzle 14. The outer side of each first fixed rod 15 is hinged to the bottom of the water supply pipe 11. Multiple connecting rods 16 are fixedly connected to the outer side of each first fixed rod 15. One end of one connecting rod 16 is rotatably connected to a turntable 17. A rotating shaft 18 is fixedly connected to one side of the turntable 17. The outer side of the rotating shaft 18 is rotatably connected to the inner side of the tower body 1. One end of the rotating shaft 18 passes through the inner side of the tower body 1 and extends to the outer side of the tower body 1. Gear 19 is fixedly connected. A servo motor 20 is fixedly connected to the outside of the tower body 1. Gear 21 is fixedly connected to the output end of the servo motor 20. A crossbar 22 is fixedly connected to one side of the tower body 1. A sliding frame 23 is slidably connected to the outside of the crossbar 22. The top of the sliding frame 23 has a toothed groove 24 and the bottom of the sliding frame 23 has a protruding tooth. The inner side of the toothed groove 24 meshes with the outer side of the gear 21. The servo motor 20 and the gear 21 reciprocate to mesh with the toothed groove 24 at the top of the sliding frame 23. The sliding frame 23 drives the three gears 19 to mesh, so that the three gears 19, the rotating shaft 18 and the turntable 17 reciprocate to swing with the three sets of connecting rods 16. Then, the connecting rods 16 drive the water mist nozzles 14 to rotate under the support of the corresponding first fixed rod 15, so that multiple water mist nozzles 14 reciprocate to swing and spray.

[0026] Reference Figure 1 and Figure 4As shown, the cooling mechanism includes a second fixed rod 25, the outer side of which is fixedly connected to the inner side of the tower body 1. A spiral baffle 26 is fixedly connected to the outer side of the second fixed rod 25. The outer side of the spiral baffle 26 is fixedly connected to the inner wall of the tower body 1. Multiple slots 27 are provided on the inner side of the spiral baffle 26. By utilizing the spiral of the spiral baffle 26 and the slots 27, the contact time between the sprayed water and the cooling pipe 4 and the second fixed rod 25 is increased.

[0027] The working principle of this utility model is as follows: When using the water-saving cooling tower, the hot water pipe is connected to the inlet pipe 3, allowing hot water to enter the interior of the cooling pipe 4 through the inlet pipe 3. The cold water pipe is connected to one end of the outlet pipe 5, allowing the hot water to circulate from top to bottom within the cooling pipe 4. Simultaneously, the cooling water at the bottom of the tower body 1 is pumped upwards into the water pipe 10 via the water pump 9 and the first water pipe 8. The cooling water is then fed into multiple second water pipes 11 via the water pipe 10. Afterwards, the servo motor 20 drives the second gear 21 to reciprocate through the toothed groove 24 at the top of the sliding frame 23, causing the sliding frame 23 to reciprocate outside the crossbar 22. Then, the protruding teeth at the bottom of the sliding frame 23 reciprocate through the multiple first gears 19 at the bottom. Finally, the three first gears 19 drive the rotating shaft 1. The 8 and turntable 17 reciprocate, and then multiple connecting rods 16 drive multiple first fixed rods 15 to reciprocate the corresponding water mist nozzles 14. Under the deflection of the corresponding two first fixed rods 15, the water mist nozzles 14 reciprocate at the bottom of the hose 13. Then, the water inside the water supply pipe 11 enters the inside of the hose 13 through multiple connecting pipes 12, and is transported to the inside of the water mist nozzles 14 through the hose 13. Then, the water mist nozzles 14 reciprocate and spray the cooling pipes 4 and the surface of the spiral baffle 26 inside the tower body 1. The air inside the tower body 1 is discharged to the outside by the fan 7 and the air outlet pipe 6. Finally, the spiral surface and grooves 27 of the spiral baffle 26 increase the air-water contact time, thereby enhancing the water film adhesion and improving the cooling efficiency.
