Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower noise reduction auxiliary devices, in particular to a low-noise cooling tower. Background Art

[0002] A cooling tower is an evaporative heat dissipation device that uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat generated in industry or refrigeration and air conditioning to reduce the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] Cooling towers generate a lot of noise during operation. This noise is generally caused by the liquid being cooled being sprayed from the nozzles at the top of the tower. As the water droplets land in the sump at the bottom, they impact the accumulated water, creating a clattering sound. Another factor is the vibration of the fan during operation, which also generates noise. Existing cooling towers lack noise reduction devices, generating a significant amount of noise during operation, leading to noise pollution. Therefore, designing a low-noise cooling tower to address these technical issues is particularly important. Utility Model Content

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] The utility model provides a low-noise cooling tower, comprising a tower body 1, wherein the bottom of the tower body 1 is evenly distributed with supporting legs 102, the top of the tower body 1 is provided with an opening 101, a shell 2 is installed on the outside of the tower body 1, and sound insulation cotton 201 is filled between the tower body 1 and the shell 2, a bracket 3 is installed on the top of the tower body 1, the bracket 3 is located above the opening 101, and buffer rods 301 are symmetrically distributed on the bracket 3, the top of the buffer rod 301 is fixedly connected to the bracket 3, the bottom of the buffer rod 301 is fixedly connected to a rectangular plate 302, the outer wall of the buffer rod 301 is sleeved with a spring 303, and the rectangular plate 302 is fixedly connected A motor 304 is rotatably connected to a rotating shaft 305, and a fan blade 306 is fixedly connected to the rotating shaft 305. A hot air inlet 4 is installed on the left side of the tower body 1. A nozzle 5 is penetrated through the tower body 1, and nozzles 501 are evenly distributed on the nozzle 5. A pump station 502 is fixedly connected to the right side of the shell 2. A water tank 503 is installed on the top of the shell 2. The water tank 503 and the pump station 502 are connected by a suction pipe 504. The nozzle 5 and the pump station 502 are connected by a delivery pipe 505. A refrigerant supply port 506 is installed on the top of the water tank 503 to ensure that the water in the water tank 503 is kept at a relatively low temperature.

[0019] When the low-noise cooling tower is actually used, a shell 2 structure is installed at the outer position of the tower body 1, and a sound insulation cotton 201 structure is filled between the shell 2 and the tower body 1. At the same time, a bracket 3 structure is set at the position of the opening 101, and a buffer rod 301 structure is symmetrically set on the bracket 3. A rectangular plate 302 structure is installed at the bottom of the buffer rod 301, and a spring 303 structure is installed on the outer wall of the buffer rod 301. When the motor 304 under the rectangular plate 302 drives the shaft 305 to drive the fan blade 306 to rotate, the rotation generated, and The spring 303 cooperates with the buffer rod 301 to disperse and reduce the noise. First, the motor 304 on the bracket 3 drives the shaft 305 to drive the fan blade 306 to rotate, generating airflow at the opening 101 position, extracting the air inside the tower body 1, and then the water supply pump cooperates with the suction pipe 504 to extract the water in the water tank 503, and then the water is transported to the nozzle 5 position by the delivery pipe 505, and finally sprayed out from the multiple groups of nozzles 501 position. The water sprayed at the nozzle 501 position is low temperature water. At this time, the hot air is discharged to the tower from the hot air inlet 4 position. Hot air is transported inside the body 1, and the hot air contacts with low-temperature water to form a mist-like airflow, which is discharged from the tower body 1 under the action of the fan blades 306 at the opening 101. The condensed water generated during the operation of the tower body 1 falls onto the permeable plate 602. Since the permeable plate 602 is made of a flexible material as a whole, the noise generated by the impact of water droplets is greatly reduced compared to that of metal materials. Then, the condensed water flows to the discharge pipe 6 under the action of the guide plate 603, and finally controls the start and stop of the stop valve 601 to be discharged from the tower body 1. By installing the shell 2 structure at the outer position of the tower body 1 and filling the space between the shell 2 and the tower body 1 with a sound insulation cotton 201 structure, the noise generated during the operation of the cooling tower can be reduced. A buffer rod 301 and a spring 303 structure are then provided on the bracket 3 to timely buffer the noise generated by the motor 304 during operation. Compared with the conventional situation where no noise reduction device is provided, the technical solution adopted by the utility model can greatly reduce the noise generated during the operation of the cooling tower and reduce noise pollution. The overall structure is directly installed on the outer wall of the tower body 1 to optimize the existing working space.

[0020] like Figure 1-2 As shown, a discharge pipe 6 is installed at the bottom of the cooling tower, and a stop valve 601 is provided on the discharge pipe 6. A water-permeable plate 602 is installed in the cooling tower. The water-permeable plate 602 is made of a flexible material. A guide plate 603 is installed below the water-permeable plate 602 in the cooling tower.

[0021] The effect achieved by the entire embodiment 1 is that, during use, the condensed water generated by the tower body 1 during operation falls onto the permeable plate 602. Since the permeable plate 602 is made of a flexible material as a whole, the noise generated by the impact of water droplets is greatly reduced compared to that of metal materials, and then flows to the discharge pipe 6 under the action of the guide plate 603.

[0022] Working principle: A shell structure is installed at the outer position of the tower body, and a sound insulation cotton structure is filled between the shell and the tower body. At the same time, a bracket structure is set at the opening position, and a buffer rod structure is symmetrically set on the bracket. A rectangular plate structure is installed at the bottom of the buffer rod, and a spring structure is installed on the outer wall of the buffer rod. When the motor drive shaft under the rectangular plate drives the fan blades to rotate, the rotation generated is promptly dispersed by the spring and the buffer rod to reduce the noise. First, the motor drive shaft on the bracket drives the fan blades to rotate, generating airflow at the opening position, extracting the airflow inside the tower body, and then the water supply pump cooperates with the fan to generate airflow. The suction pipe draws the water out of the water tank, and then transports it to the nozzle position through the delivery pipe, and finally sprayed out from multiple groups of nozzle positions. The water sprayed from the nozzle position is low-temperature water. At this time, hot air is transported to the inside of the tower body from the hot air inlet position. The hot air and low-temperature water come into contact with each other to form a mist airflow, which is discharged from the tower body under the action of the fan blades at the opening position. The condensed water generated by the tower body during operation falls onto the permeable plate. Since the permeable plate is made of flexible material as a whole, the noise generated by water droplet impact is greatly reduced compared to metal material. Then it flows to the discharge pipe under the action of the guide plate, and finally controls the start and stop of the stop valve to discharge the tower body.
