Technical Field
[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower sewage discharge device. Background Technology
[0002] Cooling towers are devices that use the contact between air and water (directly or indirectly) to cool water. They achieve the cooling effect by spraying circulating water onto the packing material, using the contact between water and air for heat exchange, and then using a fan to exhaust the hot air. Cooling towers are widely used in industrial manufacturing, commercial buildings, data centers and many other fields to provide cooling support for various equipment and processes.
[0003] Cooling towers utilize the principle of water evaporation to absorb heat and reduce the temperature of cooling water. However, during actual operation, the circulating cooling water continuously evaporates, leading to the accumulation of salts in the cooling water system. This results in scaling, corrosion, and equipment blockage, severely impacting the safe and stable operation of the system, reducing system efficiency, shortening equipment lifespan, and increasing system operation and maintenance costs. Therefore, this invention proposes a cooling tower drainage device to address these issues. Summary of the Invention

[0017] To deepen the understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a cooling tower sewage discharge device, including a collection tank 1, a settling hopper 2, and a water conveying chamber 3. The bottom of the collection tank 1 is provided with the settling hopper 2, and the outside of the collection tank 1 is welded to the water conveying chamber 3. A water outlet pipe 4 is connected to the outside of the water conveying chamber 3. A sewage discharge pipe 6 is connected to one side of the bottom of the settling hopper 2. The top of the collection tank 1 is provided with an overflow settling mechanism, and the inside of the settling hopper 2 is provided with a cleaning mechanism. Sewage discharged from the cooling tower is transported to the inside of the collection tank 1. The water flows downwards into the settling hopper 2, where scale in the wastewater settles at the bottom. Then, the clean water overflows upwards into the water tank 3 through the overflow settling mechanism, removing most of the scale. The water is then transported to an external storage device through the outlet pipe 4. The external storage device then filters the water through a pump and a filter element and returns it to the cooling tower, replenishing the consumed water. Finally, the scale at the bottom of the settling hopper 2 is cleaned out of the settling hopper 2 through the cleaning mechanism in conjunction with the drain pipe 6.
[0019] The overflow settling mechanism includes a baffle 16 and an overflow pipe 5. Multiple overflow pipes 5 are equidistantly connected to the top of the collection tank 1. The top of the settling hopper 2 is fixedly connected to the baffle 16. The top of the baffle 16 is provided with an arc-shaped notch at equal intervals. After the sewage enters the interior of the settling hopper 2, the scale settles at the bottom of the settling hopper 2, while the clean water floats up as the sewage is continuously injected until it passes over the arc-shaped notch on the baffle 16 and enters the top of the collection tank 1. Then, it overflows through the overflow pipe 5 into the interior of the water conveying chamber 3. Next, it is transported to the external storage device through the water outlet pipe 4. The external storage device then uses a pump to transport the clean water back to the interior of the cooling tower and replenish the water consumed.

The bottom end of the settling hopper 2 is rotatably connected to the rotating shaft 7, and the top end of the rotating shaft 7 is fixedly connected to the cleaning brush 8. The outer wall of the cleaning brush 8 is in close contact with the inner wall of the settling hopper 2.
[0021] The bottom end of the settling bucket 2 is fixedly connected to a fixing frame 12, and a self-locking motor 11 is fixedly installed on the top of one side of the fixing frame 12. A rotating mechanism is provided between the bottom end of the rotating shaft 7 and the self-locking motor 11.
[0022] The rotating mechanism includes pulleys 9 and belts 10. The bottom end of the settling hopper 2 and the bottom of one side of the fixed frame 12 are rotatably connected to pulleys 9. A belt 10 is connected between the two pulleys 9. The bottom end of the rotating shaft 7 passes through the bottom end of the settling hopper 2 and is fixedly connected to the top end of one of the pulleys 9. The self-locking motor 11 can drive the pulley 9 at its output end to rotate. The pulley 9 at the bottom end of the rotating shaft 7 is connected to the pulley 9 at the output end of the self-locking motor 11 through the belt 10. The self-locking motor 11 can drive the rotating shaft 7 to rotate at the bottom end of the settling hopper 2. The cleaning brush 8 is connected to the rotating shaft 7 as a whole. The rotating shaft 7 can drive the cleaning brush 8 to rotate inside the settling hopper 2. The cleaning brush 8 is in contact with the inner wall of the settling hopper 2 to scrape the scale on the inner wall of the settling hopper 2, preventing it from adhering to the settling hopper 2, and allowing it to be discharged to the outside of the settling hopper 2 along with the water flow through the drain pipe 6.
[0023] The rotating shaft 7 has a hollow structure inside, and multiple nozzles 15 are provided on the outside of the rotating shaft 7. A water conveying mechanism is provided below the settling hopper 2.
[0024] The water conveying mechanism includes a connecting pipe 13 and a water pump 14. The water pump 14 is located below the settling hopper 2. The output end of the water pump 14 is connected to the connecting pipe 13. The top end of the connecting pipe 13 is rotatably connected to the inside of the pulley 9, and the top end of the connecting pipe 13 is inserted into the inside of the rotating shaft 7. The input end of the water pump 14 is connected to an external water source. After the sewage is treated, the remaining water and settled scale inside the settling hopper 2 are discharged to the outside of the settling hopper 2 through the drain pipe 6. The water pump 14 and the connecting pipe 13 work together to deliver clean water from the outside into the inside of the rotating shaft 7. The rotating shaft 7 sprays water into the inside of the settling hopper 2 through the nozzle 15 to rinse the scale on the settling hopper 2, which plays an auxiliary role in cleaning the scale.
[0025] The cooling tower's sewage discharge device includes a self-locking motor 11 that drives the pulley 9 at its output end to rotate. The pulley 9 at the bottom of the rotating shaft 7 is connected to the pulley 9 at the output end of the self-locking motor 11 via a belt 10. The self-locking motor 11 drives the rotating shaft 7 to rotate at the bottom of the settling hopper 2. The cleaning brush 8 is integrated with the rotating shaft 7, and the rotating shaft 7 drives the cleaning brush 8 to rotate inside the settling hopper 2.
