Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a pollution removal structure of a cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant, absorbs heat from the system and discharges it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. This is an evaporative heat dissipation device to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower. When the cooling tower is in use, water flows back into the water collecting tank, which stores water all year round and is very prone to dirt. It is necessary to provide a cooling tower decontamination structure to facilitate the cleaning of the cooling tower.

[0003] The existing cooling towers have the following problems when cleaning: first, most of the cleaning needs to be done manually, which is difficult and troublesome; second, the cleaning effect on the filler is relatively limited, resulting in a shortened service life of the filler. Therefore, a cooling tower decontamination structure is provided to solve the above problems. Utility Model Content

[0028] Please refer to Figures 1-6 , an embodiment provided by the present utility model: a sewage removal structure of a cooling tower, which includes a tower bin 1, a water collecting tank 2 is installed at the lower end of the tower bin 1, a return pipe 3 is connected between the water collecting tank 2 and the tower bin 1, a cooling water pipe 4 is installed on the return pipe 3, and spray heads 5 are distributed on the cooling water pipe 4, and packing 6 is arranged in the tower bin 1;

[0029] A drive motor 7 is installed on the outer wall of the tower bin 1, and a drive wheel 8 is connected to the output end of the drive motor 7. The drive wheel 8 is meshed with a rotating wheel 9, and the rotating wheel 9 is rotatably connected to the tower bin 1. A sealing ring is installed between the rotating wheel 9 and the tower bin 1. The rotating rotating wheel 9 drives the mounting bracket 10 installed thereon to rotate synchronously. The sealing ring installed between the rotating wheel 9 and the tower bin 1 is used to prevent water leakage, facilitating the rotation of the mounting bracket 10 on the inner wall of the water collecting tank 2. The rotating wheel 9 is installed near the drive wheel 8 of the tower bin 1. The rotating wheel 9 is connected to the mounting bracket 10, and a water pump 11 is installed on the mounting bracket 10. A cleaning pipe 17 is connected to the output end of the water pump 11, and cleaning nozzles 18 are distributed on the cleaning pipe 17;

[0030] Cleaning scrapers 15 and cleaning brushes 16 are respectively installed on both sides of the mounting bracket 10. A filter cotton 12 is arranged inside the upper half of the mounting bracket 10. The mounting bracket 10 is snap-connected to the filter cotton 12, and the filter cotton 12 can be detachably installed and replaced in time to facilitate the filtration of the water sucked into the mounting bracket 10, avoiding the blockage of the water pump 11 by the recycled water. Both the cleaning scraper 15 and the cleaning brush 16 are fixedly connected to the mounting bracket 10. The cleaning scraper 15 is made of rubber and is in close contact with the inner wall of the tower bin 1. The cleaning scrapers 15 and the cleaning brushes 16 on both sides of the mounting bracket 10 clean the dirt on the inner wall of the water collecting tank 2. A water suction pipe 13 is installed at the lower half of the mounting bracket 10, and shunt suction heads 14 are distributed on the water suction pipe 13. The shunt suction heads 14 are evenly distributed at equal intervals on the water suction pipe 13. The water suction pipe 13 is communicated with the water pump 11 through the inner cavity of the mounting bracket 10. The water pump 11 operates to suck the sewage into the filter cotton 12 through the water suction pipe 13, filter the sewage, and recycle the filtered sewage, fully cleaning the cooling tower to ensure the cooling efficiency.

[0031] A connecting frame 19 is installed on the cleaning pipe 17, and a bearing 20 is arranged in the middle of the connecting frame 19.

At the same time, it flushes the inner wall of the tower bin 1 after cleaning, maintaining the cleanliness inside the tower bin 1 and the water collecting tank 2.

[0032] The water flow circulation flows at the return pipe 3, and the flowing water flows out through the cooling water pipe 4 and sprays out from the water spray head 5. At this time, the water is atomized and sprayed towards the packing 6. The driving motor 7 drives the driving wheel 8 to engage and rotate the rotating wheel 9. The rotating rotating wheel 9 drives the mounting frame 10 to rotate. The cleaning pipe 17 connected to the mounting frame 10 by the water pump 11 rotates accordingly. The connecting frame 19 connected to the middle bearing 20 of the cleaning pipe 17 assists the cleaning pipe 17 to rotate stably. The cleaning scrapers 15 and cleaning brushes 16 on both sides of the mounting frame 10 clean the dirt on the inner wall of the water collecting tank 2. The water pump 11 operates to suck the cleaned water flow into the water suction pipe 13 through the shunt suction head 14. The water flow is introduced into the cleaning pipe 17 through the water pump 11 and flushes the lower end of the packing 6 through the cleaning nozzle 18, while completing the flushing and cleaning of the water collecting tank 2.
