[0030] In this embodiment, a filter screen is inserted into the upper surface of the vent 3 , and the outer diameter of the top of the filter screen is larger than the inner diameter of the vent 3 . The filter screen can prevent dust in the air from entering.

[0031] See also Figure 2In order to evenly spray the filler 2, the spray mechanism 4 in this embodiment includes a sealing box 41, a motor 42, a rotating rod 43, a hollow rod 44, two spur gears 45, a turntable 46, a water tank 47, a water pump 48 and a water spray disc 49. The sealing box 41 is fixed to the lower surface of the inner top wall of the cooling tower body 1. The sealing box 41 can prevent hot air from directly contacting the spur gear 45, thereby protecting the service life of the spur gear 45. The motor 42 is fixed to the left end of the upper surface of the cooling tower body 1, and the output shaft of the motor 42 passes through the inner top wall of the cooling tower body 1. It extends to the inner cavity of the cooling tower body 1 and is fixed to the rotating rod 43. The hollow rod 44 is rotatably connected to the inner bottom wall of the sealing box 41 through a bearing. Two spur gears 45 are respectively fixed to the outer surfaces of the rotating rod 43 and the hollow rod 44. The two spur gears 45 are meshed and connected. When the motor 42 is started, the output shaft of the motor 42 rotates to drive the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the spur gear 45 fixed on its surface to rotate. Since the two spur gears 45 are meshed and connected, the spur gear 45 on the right can drive the hollow rod 44 to rotate.

[0032] The lower surface of the hollow rod 44 passes through the inner bottom wall of the sealing box 41 and extends to the lower side of the sealing box 41 and is fixed to the turntable 46. The water tank 47 is fixed on the right side of the cooling tower body 1, and the water pump 48 is fixed on the left end of the upper surface of the water tank 47. The spray disc 49 is fixed on the lower surface of the turntable 46. The rotation of the hollow rod 44 can drive the turntable 46 to rotate. The rotation of the turntable 46 causes the spray disc 49 fixed on its lower surface to rotate. The water entering the inner cavity of the hollow rod 44 can enter the inner cavity of the spray disc 49 along the guidance of the hollow rod 44.

[0033] In this embodiment, the rotating rod 43 is rotatably connected to the inner bottom wall of the sealing box 41 through a bearing, and the lower surface of the hollow rod 44 is connected to the inner cavity of the water spray plate 49. The water spray plate 49 includes a plurality of annular tubes with different outer diameters. The lower surface of the annular tube is connected to a plurality of evenly distributed nozzles. The plurality of annular tubes are connected by a guide pipe. The water flowing into the inner cavity of the water spray plate 49 flows into the inner cavity of the plurality of annular tubes through the guidance of each guide pipe, and then flows out from the nozzle.

The other end of the outlet pipe passes through the cooling tower body 1 and extends to the inner cavity of the sealing box 41 and is rotatably connected to the hollow rod 44 through a sealed bearing. When the water pump 48 is started, the water inlet end of the water pump 48 draws water into the inner cavity of the water tank 47 to the water outlet end of the water pump 48, and then flows into the inner cavity of the outlet pipe through the water outlet end of the water pump 48, and then flows into the inner cavity of the hollow rod 44.

[0035] It should be noted that the water spray disc 49 is driven by the turntable 46 to spray the filler 2 evenly and over a wide range, thereby facilitating cooling and greatly improving the spraying effect on the filler 2 .

[0036] See also Figures 3-4 In order to avoid waste of water resources, the filtering mechanism 5 in this embodiment includes a support box 51, two limit blocks 52, an outer frame 53 and a filter layer 54. The support box 51 is fixed on the lower surface of the cooling tower body 1. A plurality of water guide holes 55 are provided on the upper surface of the support box 51 and the lower surface of the cooling tower body 1. The two limit blocks 52 are fixed in the middle between the opposite sides of the left and right side walls of the inner cavity of the support box 51. The filter layer 54 is fixed in the inner cavity of the outer frame 53. The cooled water can enter the inner cavity of the support box 51 from the water guide holes 55 opened on the inner bottom wall of the cooling tower body 1 through the water guide holes 55 opened on the upper surface of the support box 51, and then flow out of the inner cavity of the support box 51 through the drainage pipe after being filtered by the filter layer 54, which is convenient for collection by the staff.

[0037] In this embodiment, the cross-sectional shape of the limit block 52 is an inverted T-shape, and limit grooves are provided on both the left and right sides of the outer frame 53. The size of the inner cavity of the limit groove is adapted to the size of the limit block 52. The front of the support box 51 is sealed with a sealing plate, and the bottom of the front of the sealing plate is connected to a drainage tube with one end passing through and extending to the inner cavity of the support box 51.

[0038] It should be noted that the sealing plate is pulled out of the inner cavity of the support box 51, and then the outer frame 53 is pulled outward, so that the limit grooves opened on the left and right sides of the outer frame 53 slide on the outer surface of the limit block 52 until it is completely pulled out, and the filter layer 54 can be cleaned.

[0039] It can be understood that recycling can be achieved, thereby avoiding the waste of water resources. The set limit block 52 can clean the surface of the filter layer 54, further improving the filtering effect and filtering efficiency.

[0040] The working principle of the above embodiment is:

[0041] (1) When in use, water can be added to the inner cavity of the water tank 47 through the water inlet, and then the water pump 48 is started. The water inlet end of the water pump 48 draws water from the inner cavity of the water tank 47 to the water outlet end of the water pump 48, and then flows into the inner cavity of the outlet pipe through the water outlet end of the water pump 48, and then flows into the inner cavity of the hollow rod 44. At this time, the motor 42 is started, and the output shaft of the motor 42 rotates to drive the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the spur gear 45 fixed on its surface to rotate. Since the two spur gears 45 are engaged, The spur gear 45 on the right side drives the hollow rod 44 to rotate, and the rotation of the hollow rod 44 drives the turntable 46 to rotate. The rotation of the turntable 46 causes the water spray disc 49 fixed on its lower surface to rotate. The water entering the inner cavity of the hollow rod 44 can enter the inner cavity of the water spray disc 49 as guided by the hollow rod 44, and then flow into the inner cavity of multiple annular tubes through the guidance of each guide pipe, and then flow out from the nozzle. The rotation of the water spray disc 49 can make the sprayed water flow down evenly, and the filler 2 can be evenly sprayed.

[0042] (2) The cooled water can enter the inner cavity of the support box 51 from the water guide hole 55 opened on the inner bottom wall of the cooling tower body 1 through the water guide hole 55 opened on the upper surface of the support box 51, and then flow out of the inner cavity of the support box 51 through the drainage pipe after being filtered by the filter layer 54, so that the staff can collect it. In order to facilitate the staff to clean the filter layer 54 regularly, the sealing plate can be pulled out of the inner cavity of the support box 51, and then the outer frame 53 can be pulled out so that the limit grooves opened on the left and right sides of the outer frame 53 slide on the outer surface of the limit block 52 until they are all pulled out, and the filter layer 54 can be cleaned.
