A noise reduction air compressor

Technical Field

The utility model relates to the technical field of air compressors, in particular to a noise reduction type air compressor.

Background Art

An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The air compressor is the main body of the gas source device. It is a device that converts the mechanical energy of the motor into gas pressure energy. It is mainly driven directly by the motor. The connecting rod causes the piston to reciprocate, causing the cylinder volume to change, thereby inhaling, compressing and exhausting air.

During the working process, the existing air compressor has low stability, strong vibration, and generates noise when completing the repetitive work of suction, compression and exhaust. The noise is loud and affects the working environment of the staff. A solution is proposed below to solve the above problems.

DETAILED DESCRIPTION

The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

As shown in Figures 1 and 2, a noise reduction type air compressor includes a noise reduction box 1 and an air compressor body 2. A mounting plate 3 is slidably arranged inside the noise reduction box 1, a silencer plate 4 is installed on the top of the mounting plate 3, the air compressor body 2 is installed on the top of the silencer plate 4 by bolts, a soundproof door 6 is also installed on the side wall of the noise reduction box 1, and a plurality of sealing strips are installed on the door frame of the soundproof door 6. By installing the air compressor body 2 into the noise reduction box 1 for use, not only can the noise of the air compressor body 2 be reduced, but also the air compressor can be prevented from being damaged by bumps. A soundproof glass 15 is also provided on the soundproof door 6, and the operating status of the air compressor body 2 in the noise reduction box 1 can be observed through the soundproof glass 15.

Two limit support plates 11 are symmetrically installed on the top of the silencer plate 4. The top of the limit support plate 11 is an arc-shaped structure. Rubber pads are installed on the limit support plates 11. The limit support plates 11 are in contact with the side walls of the air compressor body 2 through the rubber pads. By installing the upper limit support plates 11 on both sides of the silencer plate 4, the air compressor body 2 can be better limited and supported.

A plurality of shock absorbing members 5 are installed between the mounting plate 3 and the inner bottom wall of the noise reduction box 1. The shock absorbing members 5 are spring dampers. The air compressor body 2 will vibrate during operation. By installing the spring dampers at the bottom of the noise reduction box 1, a shock absorbing effect is achieved. When the vibration of the air compressor body 2 is reduced, the noise generated by the air compressor can also be reduced.

The inner wall of the noise reduction box 1 is also provided with a noise reduction component 7 for reducing the noise generated by the air compressor body 2. By installing the noise reduction component 7 inside the noise reduction box 1, the noise generated by the air compressor can be reduced, thereby improving the working environment of the operator.

The noise reduction component 7 includes a sound insulation board 8 and sound absorbing cotton 9. The sound insulation board 8 is installed on the side walls and the top wall of the noise reduction box 1. The sound absorbing cotton 9 is installed on the side of the sound insulation board 8 away from the noise reduction box 1. A plurality of sound absorbing wedges 10 are also installed on the sound absorbing cotton 9. By installing sound insulation boards 8, sound absorbing cotton 9, sound absorbing wedges 10 and other sound absorbing and sound insulation materials on the inner wall of the noise reduction box 1, the noise generated by the air compressor body 2 can be reduced to the maximum extent.

An air inlet 12 is also provided on the side wall of the noise reduction box 1, and a filter is installed in the air inlet 12. An electric fan 13 is installed on the air inlet 12. By starting the electric fan 13, the electric fan 13 can discharge external gas into the noise reduction box 1 for use by the air compressor body 2. The filter is installed on the hole so that the incoming air can be filtered. A number of heat dissipation holes 14 are symmetrically provided on the bottom side wall of the noise reduction box 1. The heat dissipation holes 14 correspond to the gas tank structure at the bottom of the air compressor body 2. Since the gas tank generates less noise during operation, the heat dissipation holes 14 can be made to correspond to the gas tank so as to reduce the discharge of noise from the heat dissipation holes 14.

For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
