Description

Technical Field

[0001] This utility model belongs to the field of noise reduction device technology, specifically relating to a noise reduction device for industrial chillers. Background Technology

[0002] Industrial chillers are widely used in many industrial production fields, such as chemical, pharmaceutical, and plastics processing. Their main function is to provide a stable low-temperature cooling medium to production equipment through a refrigeration cycle system, ensuring that the production process can be carried out in a suitable temperature environment, thus guaranteeing product quality and production efficiency.

[0003] However, significant noise is inevitably generated during the operation of a chiller. This noise primarily originates from several internal components. First, the compressor, as the core power component of the chiller, experiences strong mechanical vibrations during high-speed operation due to the rotation of its motor and the reciprocating motion of its piston. This vibration is transmitted throughout the chiller body via its connection structure, thus generating noise that radiates into the surrounding environment. Second, the circulating water pump, driving the flow of the cooling medium, also generates vibration noise due to the interaction between its blades and the medium, as well as the mechanical operation of the pump itself.

[0004] Traditional industrial chillers often rely solely on simple soundproof enclosures for noise reduction. While these enclosures can block noise transmission to some extent, their effectiveness in reducing mechanical vibration noise from internal components is very limited. With increasingly stringent noise control requirements in industrial production environments, and growing public concern for work comfort and safety, existing simple noise reduction methods are no longer sufficient.

By installing a first rectangular clamping plate and a second rectangular plate inside as a clamping mechanism, the chiller device is clamped. During the operation of the chiller device, the mechanical vibration of the chiller device is weakened and buffered by the displacement buffer of the first rectangular clamping plate and the second rectangular plate, thereby effectively reducing the vibration noise of the chiller device.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a noise reduction device for an industrial chiller includes a main body 1. An inlet / outlet is located on one side of the main body 1, and two protective doors 3 are rotatably connected inside the inlet / outlet. A handle 4 is fixedly connected to one side of each of the two protective doors 3. Two first rectangular clamping plates 9 are installed inside the main body 1. Multiple return springs 11 are fixedly connected to one side of each of the two first rectangular clamping plates 9, and one side of each return spring 11 is fixedly connected to the inner wall of the main body 1. First telescopic damping rods 12 are fixedly connected to the inner walls on both sides of the main body 1. A piston head at one end of each first telescopic damping rod 12 abuts against the first rectangular clamping plate 9. The first telescopic damping rod 12 is located at... Inside the return spring 11, two first rectangular clamping plates 9 are provided with positioning grooves on opposite sides. A chiller device 5 is fixedly connected inside the two positioning grooves. A second rectangular plate 10 is screwed to the lower side of the chiller device 5. Multiple shock-absorbing springs 14 are fixedly connected to the lower side of the second rectangular plate 10. A first rectangular plate 18 is fixedly connected to the lower side of the multiple shock-absorbing springs 14. A second telescopic damping rod 15 is fixedly connected to the first rectangular plate 18. The piston head at the upper end of the second telescopic damping rod 15 abuts against the lower side of the second rectangular plate 10. A sliding guide is fixedly connected to the lower side of the first rectangular plate 18. The sliding guide is fixedly connected to the lower inner wall of the noise reduction device body 1.

[0026] In use, firstly, pull out the second rectangular plate 10 and the first rectangular plate 18 through the sliding guide, and fix the chiller device 5 to the second rectangular plate 10 with screws. After installation, align the chiller device 5 with the positioning groove between the two first rectangular clamping plates 9 and slowly push it in. At this time, the multiple return springs 11 on one side of the two first rectangular clamping plates 9 will contract due to the compression of the chiller device 5. The elastic force provided by the return springs 11 can make the two first rectangular clamping plates 9 tightly clamp the chiller device 5, playing a preliminary fixing and buffering role, preventing the chiller device 5 from shaking significantly during operation. The first telescopic damping rod 12 can provide damping force during the extension or compression of the return springs 11, avoiding excessive extension or compression of the return springs 11, which would lead to increased shaking. This makes the movement of the chiller unit 5 in the lateral direction more stable, reducing vibration and noise. At the same time, the multiple shock-absorbing springs 14 between the second rectangular plate 10 and the first rectangular plate 18 can effectively reduce the vertical vibration transmission generated during the operation of the chiller unit 5. The second telescopic damping rod 15 can provide damping force during the extension or compression of the shock-absorbing springs 14, avoiding excessive extension or compression of the shock-absorbing springs 14 and resulting in increased shaking. This makes the operation of the chiller unit 5 in the vertical direction more stable, reducing vibration and noise. After the chiller unit 5 is installed, the user can pull the two handles 4 to close the two protective doors 3, thereby sealing the interior of the noise reduction device body 1, increasing the noise isolation generated when the chiller unit 5 is working, and reducing the outward transmission of noise.

[0027] like Figure 4 , Figure 5 As shown, an auxiliary housing 19 is fixedly connected to one side of the main body 1 of the noise reduction device. The auxiliary housing 19 has a hollow structure. A vacuum pump 16 is fixedly connected inside the auxiliary housing 19. An exhaust pipe 13 is fixedly connected to the outlet end of the vacuum pump 16 and extends to the outside of the auxiliary housing 19. A delivery pipe 2 is fixedly connected to the inlet end of the vacuum pump 16. One end of the delivery pipe 2 is connected to the inside of the main body 1 of the noise reduction device. When in use, the vacuum pump 16 is started. The vacuum pump 16 can extract the space inside the main body 1 of the noise reduction device through the delivery pipe 2. The extracted air is discharged through the exhaust pipe 13, thereby realizing that the inside of the main body 1 of the noise reduction device is in a vacuum state, thereby further reducing the noise generated by the chiller device 5 when it is working, thereby further improving the noise reduction effect of the main body 1 of the noise reduction device and increasing the acoustic comfort of the user's surrounding environment.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the sliding guide includes two guide rails 7, which are fixedly connected inside the main body 1 of the noise reduction device. The guide rails 7 are provided with grooves, and sliders 8 are slidably connected in both grooves. The upper side of the sliders 8 is fixedly connected to the first rectangular plate 18. In use, the first rectangular plate 18 is moved horizontally by the close cooperation between the sliders 8 and the grooves, thereby increasing the accuracy of the movement of the first rectangular plate 18.

[0029] like Figure 4 , Figure 5 As shown, sound-absorbing cotton is fixedly connected inside both positioning slots. When in use, the sound-absorbing cotton, due to its porous and loose structure, will absorb the noise generated by the chiller device 5 when it is working. When the noise is transmitted to the sound-absorbing cotton, the noise waves will enter the pores inside the sound-absorbing cotton. After multiple reflections and friction, the sound energy will be continuously converted into heat energy and consumed, thereby effectively absorbing the noise directly transmitted to the positioning slots by the chiller device 5, reducing the outward reflection and diffusion of this noise, and further improving the noise reduction effect of the entire noise reduction device body 1.

[0030] like Figure 5 As shown, a circular hole is provided on the main body 1 of the noise reduction device. One end of the delivery pipe 2 is inserted into the interior of the main body 1 of the noise reduction device through the circular hole. A sealing ring 17 is fixedly connected to the circular hole. The sealing ring 17 is sleeved on the outside of the delivery pipe 2. In use, the sealing ring 17 can effectively prevent the gas in the main body 1 of the noise reduction device from leaking from the gap between the circular hole and the delivery pipe 2, ensuring the sealing of the entire gas delivery passage in the main body 1 of the noise reduction device. At the same time, it also helps to maintain the stable gas pressure inside the main body 1 of the noise reduction device, ensuring that the vacuum pump 16 can work normally and efficiently, and increasing the good noise reduction effect of the main body 1 of the noise reduction device.

[0031] like Figure 5 As shown, a mounting hole is provided on the first rectangular plate 18, and a first electric push rod 20 is fixedly connected in the mounting hole. The piston rod of the first electric push rod 20 abuts against the lower side of the second rectangular plate 10. In use, the first electric push rod 20 is started. During the extension and retraction of the piston rod of the first electric push rod 20, the chiller device 5 can be pushed into the height that matches the positioning groove of the two first rectangular clamping plates 9 through the second rectangular plate 10, thereby realizing the compatibility between the positioning groove and the chiller device 5. After the first rectangular clamping plates 9 have clamped the chiller device 5, the piston head of the first electric push rod 20 is reset, releasing the first electric push rod 20 from limiting the second rectangular plate 10.

[0032] like Figure 1 , Figure 4 , Figure 5As shown, a second electric push rod 21 is fixedly connected to both sides of the noise reduction device body 1. The piston rod of the second electric push rod 21 extends into the body 1 of the noise reduction device and is fixedly connected to an electromagnet. A magnetic block is fixedly connected to the first rectangular clamping plate 9. When the electromagnet is energized, it can magnetically attract the magnetic block. When in use, the electromagnet is energized, and the energized electromagnet will generate a magnetic field. It magnetically attracts the magnetic block on the first rectangular clamping plate 9 by means of its magnetic force. Then, through the extension and retraction of the piston rod of the second electric push rod 21 and the attraction between the electromagnet and the magnetic block, the position movement of the first rectangular clamping plate 9 can be more precisely controlled, so as to clamp or release the chiller device 5 when the first rectangular clamping plate 9 moves.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
