Description

Technical Field

[0001] The utility model relates to the technical field of square cross-flow cooling towers, in particular to a square cross-flow low-noise cooling tower. Background Art

[0002] The square cross-flow cooling tower uses air inlet on both sides and a fan on the top to allow the air to pass through the fillers on both sides of the tower to exchange media with hot water, and the hot and humid air is then discharged outside the tower. The water flow of the cross-flow cooling tower falls vertically from the top of the tower, and the air flows horizontally through the water-spraying fillers. The airflow and water flow are orthogonal to the cooling tower.

[0003] Some existing square cross-flow cooling towers usually pass water through the top to discharge the aqueous solution to be cooled into the cooling tower. During use, a lot of noise will be generated when the discharged water hits the inner wall of the cooling tower. At the same time, when the cooling water falls into the sump, it will also generate a lot of noise, causing noise pollution to the surrounding environment and causing great trouble to nearby residents. The practicality is low. In view of this, we propose a square cross-flow low-noise cooling tower to solve the above problems. Utility Model Content

When the water flow contacts the absorbent cotton net and the mounting frame 4, the impact force of the water flow will cause the mounting frame 4 to tilt downward between the two fixed blocks 5. At this time, the rotating shaft 6 will rotate, and the first torsion spring 8 will stretch, thereby achieving the purpose of reducing the impact force of the water flow and reducing noise. At the same time, the arrangement of the absorbent cotton net 9 can enable the fan inside the fan compartment 11 to draw out the water vapor inside the cooling tower body 1 when it is working. When the water vapor passes through the absorbent cotton net 9, part of the water vapor in the water vapor will be absorbed, thereby reducing the flow of water. loss and evaporation, the above structure solves the problem that some existing square cross-flow cooling towers will cause different degrees of noise pollution, and avoids the noise pollution caused by water flow impacting the inner wall of the cooling tower as much as possible. The impact of water flow on the cooling tower body 1 is gradually reduced by the setting of three mounting frames 4. At the same time, the setting of silencer cotton 10 can further reduce the noise generated by the impact of water flow on the mounting frame 4 itself, thereby reducing the generation of noise and the impact of the device on the environment. At the same time, the setting of the filling cavity 13 inside the fan compartment 11 also reduces the noise generated by the fan inside the fan compartment 11, and the practicability is relatively high.

[0029] In the above embodiment, sound insulation cotton may be provided on the inner wall of the cooling tower body 1 to absorb the noise generated inside the cooling tower body 1 .

[0030] Furthermore, a second cavity 14 is provided inside the mounting block 3, and a rotating rod 15 is rotatably connected inside the second cavity 14. The rotating rod 15 rotates and passes through the mounting block 3. A cam 16 is sleeved on the outer surface of the rotating rod 15. Two fixed rods 17 are provided inside the second cavity 14. The two fixed rods 17 are respectively located on both sides of the cam 16. Both fixed rods 17 slide through the mounting block 3.

[0033] When the staff needs to replace the absorbent cotton net 9 or the sound-absorbing cotton 10, the rotation of the cam 16 is driven by rotating the rotating rod 15, and the second torsion spring 19 will be stretched. At this time, the cam 16 will not squeeze the two fixing rods 17. At this time, relying on the elastic force of the reset spring 21 itself, the two fixing rods 17 will move to the middle, and then the two fixing rods 17 will no longer be located inside the two fixing grooves 18, and the mounting block 3 will no longer be fixed. At this time, the staff can disassemble the mounting block 3. When it is necessary to install the mounting block 3, the two fixing rods 17 are retracted into the mounting block 3 by rotating the rotating rod 15, and then the mounting block 3 is slid into the mounting groove 2, and then the rotating rod 15 is reset by relying on the elastic force of the second torsion spring 19 itself, and then the cam 16 will push the two fixing rods 17 to both sides, so that the fixing rods 17 are stuck in the fixing grooves 18. The above structure is convenient for the staff to disassemble and replace the absorbent cotton net 9 and the sound-absorbing cotton 10, further improving the flexibility and practicality of the device, simple operation, convenient and fast, and high disassembly efficiency.

[0034] Furthermore, ball grooves 22 are provided on the surfaces of the opposite sides of the two fixed rods 17, and movable balls 23 are movably connected inside the ball grooves 22. By making the movable balls 23 contact the surfaces of the cam 16, the friction between the cam 16 and the fixed rods 17 is reduced, thereby improving the smoothness and stability of the operation of the device and increasing the service life of the device.

[0035] Furthermore, a filter screen 25 is disposed on the upper surface of the exhaust duct 12 , and the filter screen 25 is effectively configured to prevent external dust from entering the interior of the cooling tower body 1 .

[0037] Working principle:

[0038] When the square cross-flow low-noise cooling tower is in use, cooling water is discharged from the water inlet 24 into the interior of the cooling tower body 1. At this time, the water flow will fall vertically. When the water flow contacts the absorbent cotton net and the mounting frame 4, the impact force of the water flow will cause the mounting frame 4 to tilt downward between the two fixed blocks 5. At this time, the rotating shaft 6 will rotate, and the first torsion spring 8 will stretch, thereby achieving the purpose of reducing the impact force of the water flow and reducing noise. At the same time, the absorbent cotton net 9 is arranged so that the fan inside the fan compartment 11 can draw out the water vapor inside the cooling tower body 1 when it is working. When the water vapor passes through the absorbent cotton net 9, part of the water vapor in the water vapor will be absorbed, thereby reducing the loss and evaporation of water.
