Description

Technical Field

[0001] This utility model belongs to the field of noise reduction technology for circulating cooling water towers, specifically relating to a sound insulation and noise reduction device for circulating cooling water towers. Background Technology

[0002] In industrial production, circulating cooling towers are indispensable key components among numerous pieces of equipment, especially widely used in industries such as chemical, power, and metallurgy. Their core function is to dissipate the large amounts of heat generated during industrial production through heat exchange between water and air, thereby ensuring stable operation of the equipment in a suitable temperature environment and guaranteeing the continuity and efficiency of the entire production process.

[0003] However, circulating cooling towers inevitably generate a series of problems during operation, among which noise and vibration are particularly prominent. Circulating cooling towers are typically equipped with power equipment such as fans. When the fans rotate at high speed, they drive airflow, generating strong aerodynamic noise. Simultaneously, the impact and splashing of water inside the tower, as well as the friction and vibration between equipment components, also cause mechanical noise. These noises are often high in intensity and have a wide propagation range, causing serious noise pollution to the surrounding environment. Prolonged exposure to high noise levels not only affects the physical and mental health of workers, leading to hearing loss and neurasthenia, but also disrupts normal production order and reduces work efficiency. Furthermore, during the operation of circulating cooling towers, factors such as fan operation, uneven water flow impact, and unstable equipment foundations all cause varying degrees of vibration in the tower body. This vibration not only accelerates the wear and aging of equipment components, shortens the equipment's lifespan, increases maintenance costs and production downtime, but also generates noise. Therefore, this application proposes a sound insulation and noise reduction device for circulating cooling towers. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment provides a sound insulation and noise reduction device for circulating cooling towers, the structural schematic diagram of which is shown below. Figures 1-4 As shown, it includes a circulating cooling tower body 1, a vibration isolation base 2, a fan 3, and an air intake noise reduction mechanism 4.

[0021] In this embodiment, the vibration isolation base 2 is disposed at the bottom of the circulating cooling tower body 1. The vibration isolation base 2 is used to support the circulating cooling tower body 1 and absorb and disperse the vibration energy generated during the operation of the circulating cooling tower body 1, so as to reduce the noise generated by vibration. The vibration isolation base 2 includes an upper plate 5, a lower plate 6, and a vibration isolation plate 7. The upper plate 5 is horizontally disposed above the lower plate 6, and the circulating cooling tower body 1 is assembled onto the upper plate 5 by conventional methods such as bolts. The vibration isolation plate 7 is sandwiched between the upper plate 5 and the lower plate 6, and the vibration isolation plate 7 has elastic deformation properties and can be made of elastic materials such as rubber.

[0022] Furthermore, the vibration isolation plate 7 has several horizontally arranged pressure relief holes 9, which are crisscrossed and interconnected within the plate. The end of each pressure relief hole 9 penetrates the side of the vibration isolation plate 7. This structural design allows the internal pressure to be balanced through the pressure relief holes 9 when the vibration isolation plate 7 is deformed under pressure, further improving the vibration isolation effect. Simultaneously, a first sound-absorbing cotton 12 is attached to the inner wall of each pressure relief hole 9. The first sound-absorbing cotton 12 can absorb some of the noise generated by vibration, further reducing noise propagation.

[0023] In this embodiment, to enhance the connection stability between the upper plate 5 and the lower plate 6, multiple rivets 8 are connected between the upper plate 5 and the lower plate 6. The rivets 8 penetrate the vibration isolation plate 7, firmly connecting the upper plate 5, the vibration isolation plate 7, and the lower plate 6 together. Mounting strips 10 are provided on both sides of the lower plate 6, and mounting holes 11 are provided on the mounting strips 10. Through the mounting holes 11, the entire vibration isolation base 2 can be fixed to the ground or other supporting structure, ensuring the stability of the device.

[0024] As a preferred technical solution in this embodiment, the top of the circulating cooling tower body 1 has a fan 3, and an air intake noise reduction mechanism 4 is provided above the fan 3. The air intake noise reduction mechanism 4 includes a ring seat 13 fixed to the top of the fan 3, and a protruding edge 14 is provided at the bottom end of the ring seat 13. The protruding edge 14 is used to connect with the fan 3, which can be done by bolt connection or snap-fit ​​connection.

[0025] The ring seat 13 contains a dustproof mesh 15 and a second sound-absorbing cotton 16. Both the dustproof mesh 15 and the sound-absorbing cotton 16 are fitted with assembly rings 17. A retaining ring 18 is also provided inside the ring seat 13. The assembly rings 17 allow the dustproof mesh 15 and the second sound-absorbing cotton 16 to be stacked on top of the retaining ring 18 on the inner wall of the ring seat 13. The dustproof mesh 15 prevents dust and other impurities in the air from entering the circulating cooling tower 1, ensuring the cleanliness of the tower's interior. The second sound-absorbing cotton 16 absorbs the noise generated by the fan 3 during operation, reducing noise transmission through the air inlet. Furthermore, a third sound-absorbing cotton 19 is also provided on the inner wall of the ring seat 13, located below the retaining ring 18, further enhancing the noise reduction effect of the air intake noise reduction mechanism 4.

[0026] Working principle: When the circulating cooling tower 1 is in operation, vibrations will occur. The vibration isolation plates 7 in the vibration isolation base 2, due to their elastic deformation properties, can absorb and disperse the vibration energy generated by the circulating cooling tower 1. During vibration, the vibration isolation plates 7 deform, and their internal pressure relief holes 9 can balance the internal pressure, preventing damage to the vibration isolation plates 7 due to uneven pressure, while ensuring the vibration isolation effect. The upper plate 5 and the lower plate 6 are connected by rivets 8 to form a stable whole, transmitting the vibration of the circulating cooling tower 1 to the lower plate 6, which is then fixed to the ground by the mounting strips 10 on both sides of the lower plate 6, reducing the propagation of vibration to the surrounding environment.

[0027] In terms of sound absorption, the first sound-absorbing cotton 12 on the inner wall of the pressure relief hole 9 inside the vibration isolation plate 7 can absorb some of the noise generated by vibration. The second sound-absorbing cotton 16 and the third sound-absorbing cotton 19 in the air intake noise reduction mechanism 4 can absorb the noise generated by the fan 3 during operation, reducing the noise transmitted to the outside through the air intake. The dust filter 15, while blocking dust, can also block and reflect sound to a certain extent, further reducing the transmission of noise.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
