Silent tank structure for air compressors

Abstract

This utility model relates to the field of aerodynamic drive equipment technology, and in particular to a silent tank structure for an air compressor. It includes an air tank and a mounting base plate fixed to the top of the air tank. An air inlet channel is formed in the middle of the air tank, penetrating the tank and extending to a mating space at its inner end. The air storage chamber of the air tank is relatively sealed to the air inlet channel. The compressor is completely sealed within the mating space, and the noise generated by the compressor is completely contained within this space, significantly reducing noise outside the mating space. In practical applications, the air drawn in by the compressor first enters the mating space from the bottom of the air tank through the air inlet channel. Then, the compressor draws air from the mating space back into the air tank. This air extraction process not only improves the compressor's heat dissipation, allowing cool air to enter the mating space from the bottom through the air inlet channel, but also effectively solves the noise overflow problem, resulting in lower overall noise and better quietness.

Description

Technical Field

[0001] This utility model relates to the field of aerodynamic drive equipment technology, and in particular to a silent tank structure for an air compressor. Background Technology

[0002] An air compressor, also known as an air compressor unit, is a key industrial device used to compress gas, increase gas pressure, and deliver gas. It is widely used in manufacturing, construction, chemical, and medical fields, providing power for various pneumatic tools and equipment. Currently, common air compressors on the market typically consist of an air compressor and an air tank that serves as both a base and a storage unit. The air compressor is directly bolted to the top of the air tank. This integrated "top-mounted" design offers advantages such as compact structure and small footprint. However, this traditional design has significant inherent drawbacks, primarily in the conflicting issues of noise and heat dissipation, which are difficult to balance effectively.

[0003] First, noise is a significant problem. When an air compressor is working, its internal motor and compression mechanism (such as pistons and screws) generate strong mechanical vibrations and aerodynamic noise. Because the main unit is rigidly fixed directly to the air tank, its vibrations are transmitted to the entire air tank shell without any attenuation, making the air tank act like a huge "amplifier," producing strong resonance and resulting in a very high overall noise level. This causes serious noise pollution to the working environment and harms the health of operators.

[0004] Secondly, the heat dissipation performance is poor. During the air compressor's compression process, the motor and compression components generate a significant amount of heat. In existing technology, the main unit is tightly mounted above the air tank, with its bottom in close contact with the top surface of the tank. This layout severely hinders heat dissipation from the main unit, especially from its bottom and sides. Poor airflow around the main unit creates a localized "heat accumulation" area, resulting in low heat dissipation efficiency.

[0005] More importantly, noise reduction and heat dissipation are difficult to achieve simultaneously. To reduce the aforementioned noise, those skilled in the art typically consider adding soundproof covers or sound-absorbing materials to the main unit. However, this approach further worsens the heat dissipation conditions of the main unit, leading to heat buildup. Prolonged high-temperature operation significantly reduces the insulation performance, lubrication effect, and operating efficiency of the main unit, accelerating the wear and aging of motors and moving parts, and shortening the lifespan of the equipment. Conversely, if high-powered fans or numerous ventilation holes are used to improve heat dissipation, noise will propagate outwards without obstruction, greatly reducing the noise reduction effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a silent air compressor that can significantly reduce the noise of the air compressor during operation and effectively improve the heat dissipation problem.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a silent tank structure for an air compressor, comprising an air storage tank and a mounting plate fixed to the top of the air storage tank. The air storage tank is a vertically placed cylinder. A sealing cover is installed on the top of the air storage tank. The mounting plate for mounting the compressor is located in the space formed by the sealing cover and the top of the air storage tank. An air inlet channel is opened in the middle of the air storage tank, penetrating the air storage tank and extending to the mating space. The air storage chamber of the air storage tank is relatively sealed to the air inlet channel. The inner diameter of the air storage tank is 5 to 10 times the inner diameter of the air inlet channel.

[0008] Preferably, the air inlet of the air tank is located at the top of the air tank, and the air inlet is connected to the air outlet of the compressor through an air inlet pipe, which is completely sealed within the space formed by the sealing cover and the top of the air tank.

[0009] Preferably, the inner diameter of the air intake channel is greater than 3 cm, and the inner diameter of the air intake channel is 6 to 10 times the inner diameter of the air intake nozzle.

[0010] Preferably, the upper end of the air intake channel is located below the mounting base plate, the lower end of the air intake channel is located in the middle of the bottom surface of the air tank, and the air tank is provided with support parts around its perimeter.

[0011] Preferably, the support portion is formed by extending downward from the edge of the gas storage tank, and the support portion has multiple air inlets.

[0012] Preferably, the air intake channel is filled with filter cotton.

[0013] Preferably, a soft rubber ring is provided at the mating connection between the sealing cap and the top of the gas storage tank.

[0014] Preferably, the inner wall of the sealing cover is lined with sound-absorbing cotton.

[0015] Preferably, the top of the sealing cover is provided with a ventilation hole, and a ventilation fan is installed in the ventilation hole.

[0016] Preferably, the upper outer wall of the gas storage tank is equipped with a pressure gauge for detecting the gas pressure inside the gas storage tank, and the lower outer wall of the gas storage tank is equipped with a pressure relief valve.

[0017] The beneficial effects of this utility model are as follows: This utility model provides a silent tank structure for an air compressor. When the silent tank structure of this utility model is assembled into an air compressor device, the compressor is fixedly mounted on the mounting base plate. In the actual operation of the air compressor, the compressor is completely sealed within the mating space, and the noise generated by the compressor is completely contained within the mating space, significantly reducing the noise outside the mating space. The air drawn in by the compressor first enters the mating space from the bottom of the air tank through the air intake channel, and then the compressor draws the air from the mating space into the air tank. This air extraction process not only improves the heat dissipation of the compressor, but also effectively solves the problem of noise overflow, resulting in lower overall noise and better quietness.

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figures 1 to 3 As shown, a silent tank structure for an air compressor includes an air tank 1 and a mounting plate 14 fixed to the top of the air tank 1. The air tank 1 is a vertically placed cylinder. A sealing cover 3 is installed on the top of the air tank 1. The mounting plate 14 for mounting the compressor 2 is located in the space formed by the sealing cover 3 and the top of the air tank 1. An air inlet channel 12 is opened in the middle of the air tank 1, penetrating the air tank 1 and extending to the mating space at its inner end. The air storage chamber of the air tank 1 is relatively sealed to the air inlet channel 12. The inner diameter of the air tank 1 is 5 to 10 times the inner diameter of the air inlet channel 12.

[0023] When the silent tank structure of this utility model is assembled into an air compressor, the compressor 2 is fixedly mounted on the mounting base plate 14. During actual operation of the air compressor, the compressor 2 is completely sealed within the mating space, and the noise generated by the compressor 2 is completely contained within this space, significantly reducing noise outside the mating space. The air drawn in by the compressor 2 enters the mating space from the bottom of the air tank 1 through the intake channel 12, and then the compressor 2 draws the air from the mating space back into the air tank 1. This air extraction process not only improves the heat dissipation of the compressor 2, allowing cool air to enter the mating space from the bottom through the intake channel 12, but also effectively solves the noise overflow problem, resulting in lower overall noise and better quietness.

[0024] In this embodiment, the air inlet 13 of the air storage tank 1 is located on the top of the air storage tank 1. The air inlet 13 is connected to the air outlet of the compressor 2 through an air intake pipe. This air intake pipe is completely sealed within the space formed by the sealing cover 3 and the top of the air storage tank 1. The inner diameter of the air intake channel 12 is 6 to 10 times the inner diameter of the air inlet 13. The air inlet 13 and the air intake pipe are completely sealed within the mating space, effectively preventing noise transmission and ensuring a reliable noise reduction effect. At the same time, it reduces the exposure of pipelines, resulting in higher safety and reliability, and a more aesthetically pleasing and neat appearance. Setting the inner diameter of the air intake channel 12 to be much larger than the inner diameter of the air inlet 13 avoids excessively fast gas flow in the air intake channel 12, which could generate new noise, resulting in a significant noise reduction effect.

[0025] In this embodiment, the inner diameter of the air intake channel 12 is greater than 3 cm, and the inner diameter of the air intake channel 12 is 6 to 10 times the inner diameter of the air intake nozzle 13. The inner diameter of the air intake channel 12 is greater than 3 cm to ensure that the air intake channel 12 has a completely sufficient airflow, and under this premise, to reduce the gas flow velocity in the air intake channel 12, reduce noise generation, and at the same time avoid the air intake channel 12 occupying too much internal space of the air storage tank 1, thus affecting the space utilization rate of the air storage tank 1.

[0026] In this embodiment, a mounting base plate 14 is provided on the top of the gas storage tank 1, and the fixing feet 21 of the compressor 2 are fixedly connected to the mounting base plate 14. The soft sound-absorbing pad 11 is located in the gap between the mounting base plate 14 and the fixing feet 21. While improving the installation firmness of the compressor 2, the resonance between the tank body of the gas storage tank 1 and the compressor 2 is effectively reduced, the generation of noise is suppressed, and the noise pollution is lower.

[0027] In this embodiment, the upper end of the air intake channel 12 is located below the mounting base plate 14, and the lower end of the air intake channel 12 is located in the middle of the bottom surface of the air storage tank 1. Support portions 15 are provided around the air storage tank 1. Specifically, the support portion 15 extends downward from the edge of the air storage tank 1, and the support portion 15 has multiple air intake holes 19. This not only solves the problems of supporting and leveling the air storage tank 1, avoiding direct contact between the air storage tank 1 and the ground and causing wear, but also effectively solves the problems of concealing the air intake and low noise. The structure is simple, the noise is low, and it is highly practical.

[0028] In this embodiment, the air intake channel 12 is filled with filter cotton. On the one hand, it prevents external dust from entering the mating space through the air intake channel 12, ensuring the cleanliness of the compressor 2 in the mating space and preventing the compressor 2 from sucking in dust and affecting its service life. On the other hand, it effectively prevents noise from being transmitted from the mating space, further improving the quietness effect.

[0029] In this embodiment, a soft rubber ring 18 is provided at the mating connection between the sealing cap 3 and the top of the gas tank 1, which improves the sealing performance between the top of the gas tank 1 and the sealing cap 3, and the noise is strictly sealed within the mating space, resulting in less external noise pollution.

[0030] In this embodiment, the top of the sealing cover 3 is provided with a ventilation hole 32, which is equipped with a ventilation fan 31 to draw the air out of the mating space, accelerate the air flow in the mating space, draw out the hot air around the compressor 2, improve the heat dissipation effect of the compressor 2, and make it stable and reliable.

[0031] In this embodiment, a pressure gauge 16 for detecting the gas pressure inside the gas tank 1 is installed on the upper outer wall of the gas tank 1, which allows the user to monitor the gas pressure inside the gas tank 1 at any time. A pressure relief valve 17 is installed on the lower outer wall of the gas tank 1 to prevent excessive gas pressure inside the gas tank 1 from damaging the tank structure, thus improving reliability.
