Description

Silencer mounting reflection plate and compressor having silencer

The present invention relates to a silencer having a reflector and a compressor using the silencer. In particular, a plurality of resonant chambers having a circular shape are continuously connected to each other on both sides of the silencer, and reflectors are provided to reflect the noise in each of the resonant chambers. When the noise generated in the compression process passes through the resonance chamber, it is reflected on the side wall and the reflector of the resonance chamber to slow down its progress. Due to this structure, its size can be made small so that it is easy to manufacture and install. It relates to a silencer having a reflector and a compressor using the silencer.

There are various kinds of silencers according to the use, and as an embodiment of the present disclosure, a silencer that reduces noise generated when compressing air will be described.

Compression of air is generally performed by a piston compression air compressor, as shown in FIGS. 1 and 2. The air compressor 1 is installed on the head 2 and the upper part of the head 2 to suck and compress air. Connecting to raise and lower the manifold 3 which provides the flow path of the air sucked into the said head 2 and discharged from this head 2, and the piston 4 accommodated in the compression chamber of the said head 2. As shown in FIG. A pulley 6 connected to the rod 5, a motor (not shown) for providing power to rotate the pulley 6, and a storage tank 7 for storing compressed air discharged from the head 2; .

This air compressor is driven by the motor when the pulley (6) connected to the power transmission member rotates to lower the piston (4) of the head (2) the outside air is inlet (3a) of the manifold (3) Through the inlet 9 of the valve 8 to close the compression chamber of the head 2 and into the compression chamber of the head 2, and then to the piston by the continuous rotation of the pulley 6. (4) rises to compress the sucked air. The compressed air is discharged through the outlet 10 of the valve 8 through the outlet 11 of the manifold 3 and then transferred to the storage tank 7 through the supply pipe 12 connected to the outlet. And stored.

However, since the air sucked in the process of compressing the air is sucked into the suction port 9 while pressing the upper surface of the valve 8, the check valve 13 installed above the discharge port 10 is driven by the pressing force of the suction air. The outlet 10 is blocked, but the dull noise is largely generated. In addition, since the compressed air discharged by the compressed air is discharged to the discharge port 10 while pressing the bottom of the valve 8, the check valve 14 installed at the suction port 9 of the bottom face receives the suction port 9 by the pressing force of the discharge air. The noise is also generated at this time.

Such noise is continuously generated while compressing the air, thereby harming the working environment, such as sharpening the worker's nerves beyond the degree of noise pollution, and thus reducing the working efficiency. In addition, when working for a long time in such a noise-producing work environment, there was also a problem of deteriorating health such as hearing loss of the worker.

In order to solve these problems, a conventional silencer is also attached to the compressor, but the silencer was mostly composed of foam or glass fiber made of synthetic resin. Since the foam or glass fiber is installed at the inlet of the head to which air is introduced, it has a filtration function. Therefore, the noise blocking effect is very low. Actually, after the noise is measured and removed, The noise was measured, but the noise reduction effect was almost negligible, indicating that the emphasis was placed on the filtration function.

Therefore, there is an urgent need for a silencer that effectively removes such noise and a compressor equipped with the silencer.

Hereinafter, a configuration of a silencer having a reflector according to the present invention and a compressor using the silencer will be described in detail with reference to the accompanying drawings.

Figure 3 is a side view of a compressor equipped with a silencer according to the present invention, Figure 4 is a front view of a compressor equipped with a silencer according to the present invention, Figure 5 shows an exploded perspective view of the silencer according to the present invention.

As shown in the figure, the silencer 20 according to the present invention is largely equipped with a silencer 23 having a reflector 22 formed in the resonance chamber 21, and a flow path of air sucked into and discharged from the bottom of the silencer 23. The valve plate 24 is provided, and the cover 25 is attached to an upper surface of the silencer 23 to close the resonance chamber 21 while maintaining airtightness.

The noise plate 23 is to remove the noise, the configuration is as shown in Figures 5 to 12 a plurality of resonance chambers 21 are in communication with each other on the upper and lower sides of the plate-like body to form a flow path, the upper surface The first resonance chamber 21 of is in communication with the inlet 26 of the body and the last resonance chamber 21 of the upper surface is communicated by the first resonance chamber 21 of the lower surface and the passage 27 so that the upper and lower sides The resonant chamber of will form a single flow path.

Each resonance chamber 21 of the sound plate 23 is in communication with each other and arranged in a line by the incision 28, so that a large number can be formed by utilizing the narrow area, that is, in order to increase the density in the drawing It is preferable to arrange continuously in a zigzag form in a straight direction and a lateral direction as in the like to have a maze shape.

An inlet 26 for supplying air to the resonance chamber 21 is formed at the side of the silencer 23, and the inlet 26 is a guide passage continuous with the first resonance chamber 21 formed on the upper surface. (29). The inlet 26 is equipped with a filter C for filtering air.

The resonance chamber 21 is preferably recessed in a circular shape so that noise can be incident and reflected at the same angle, and is reflected in the cutout portion 28 connecting the resonance chambers 21 innumerably. Reflective plate 22 is formed to reflect and return the noise when the noise to perform the incident to the adjacent resonant chamber 21 through the incision (28).

In the first embodiment of the resonance chamber 21, as shown in Figs. 7 and 8, the inner wall on which the noise is reflected is smoothly processed while having a circular shape. In the resonance chamber 21, as shown in FIG. 16, the incident angle θ and the reflection angle θ 'of the noise are the same about the center of the resonance chamber 21, and thus, as shown in FIG. A circle 30 is formed on the path through which the noise tangentially meets the noise, and the circle 30 is a path through which all the reflected noise passes.

Therefore, the noise continuously performing the reflection while drawing such a trajectory gradually decreases as the reflection progresses, and this decrease becomes more severe each time it passes the resonance chamber 21, and finally the noise passes when the last resonance chamber 21 passes. Will be significantly reduced.

In the second embodiment of the resonance chamber 21, as shown in FIG. 9, a diffuse reflection surface 31 is formed to diffuse and reflect the noise reflected from the inner wall of the resonance chamber 21 in various directions. 31) consists of a myriad of slopes. Since the diffuse reflection surface 31 diffuses and reflects the noise in various directions, it has the effect of further reducing the noise by the diffuse reflection while satisfying the noise reduction effect as in the first embodiment.

In the third embodiment of the resonance chamber 21, as shown in FIG. 10, a ring shape is formed on a path through which all the noises reflected on the inner wall pass, that is, the noise is reflected and tangential to the predetermined circle 30. The sound absorbing agent 32 which has is provided. Since the sound absorbing agent 32 is formed in a state where the circular trajectory in which the noise is drawn is located concentrically with the center of the resonance chamber 21 and has a constant radius, the sound absorbing agent 32 may have the same radius as the radius.

Here, since the circular trajectory of the noise varies depending on the size of the resonance chamber 21 and the incident angle θ into which the noise is introduced, the ring-shaped sound absorbing agent 32 having a different size may be positioned inside the resonance chamber 21. Through experiments, when the noise is sharply reduced, the location where the sound absorbing agent 32 is disposed will be confirmed to be a circular trajectory. Therefore, through these experiments, even in the case of each resonant chamber 21 having a different size, it is easy to find a circular trajectory drawing noise.

The sound absorbing agent 32 is made of a material that can withstand air pressure while being strong against heat.

The reflection plate 22 is installed on the noise flow path consisting of the resonance chamber 21 to reflect the noise passing through the flow path to increase the noise reduction effect by reducing the traveling speed, and the noise is reflected as shown in the drawing It is preferable to be curved in an arc shape so that it is easy to return, and it arrange | positions so that a concave part may oppose a noise incident direction so as to collide with the incident noise.

In this case, the reflecting plate 22 is disposed at a central portion between the cutout portion 28 connecting the resonance chamber 21 and the center of the cutout portion 28 and the adjacent resonance chamber 21 to improve reflection efficiency. The two ends are sufficiently spaced apart from the inner wall of the resonance chamber 21 so as not to disturb the flow of the supply.

The valve plate 24 is attached to the lower surface of the silencer 23 to guide the supply of external air to the compression system, and to discharge the air discharged from the compression system to the outside.

The valve plate 24 is attached to the lower surface of the silencer 23 to close the resonance chamber 21 in a state of airtightness, and a position corresponding to the last resonance chamber 21 on the lower surface of the silencer 23. An inlet 33 through which the air passing through the sound absorbing plate 23 flows in is penetrated, and a lower surface of the body communicates with the inlet 33 to discharge air from the suction chamber 34 and the compression system. The discharge chamber 36 in which the discharge hole 35 for discharging the compressed air is formed is divided by the partition wall 37.

Here, both the suction chamber 34 and the discharge chamber 36 are located above the compression chamber of the compression system, so that the suction chamber 34 is the inlet 33 when the piston 4 of the compression chamber descends for air suction. The air introduced through the air is supplied to the compression chamber, and the discharge chamber 36 receives the compressed air and discharges it to the discharge hole 35 when the piston 4 rises to compress the air. The discharged air is not discharged to the suction chamber 34 by the check valve 14 of the compression system. This air flow will be described in detail in the compressor 100 to be described later, which is used as a compression system, and a detailed description thereof will be omitted.

The cover 25 is attached to the upper surface of the silencer 23 to seal the resonance chamber 21 to maintain airtightness, and has a plate-like body as shown in FIG. 5.

In addition, the silencer 23 and the cover 25 are provided with fastening holes 25a and 23a for fastening the bolts B to respective corners, and the valve plate 24 is fastening hole 25a. A screw hole 24a for fastening and fixing the sound absorbing plate 23 and the cover 25 is formed by the bolt B at a position corresponding to 23a.

Next will be described in detail the process of reducing the noise of the silencer 20 of the present invention configured as described above.

The cover 25 and the valve plate 24 are positioned above and below the silencer 23, and the bolts 25 are fastened to the fastening holes 25a and 23a and the screw holes 24a of the cover plate 25 and the cover 25. The silencer 20 is assembled by fastening the silencer 23 and the valve plate 24. The supply pipe 12 of the compressor 100 is connected to the discharge hole 35 of the silencer 20 thus assembled.

External air flows into the inlet 26 of the silencer 20 by the lifting and lowering drive of the piston 4 of the compressor 100. The air introduced as described above is introduced into the first resonance chamber 21 formed in the upper portion of the silencer 20 communicating with the inlet 26 through the guide passage 29 of the silencer 20 as shown in FIGS. 5 to 13. Passing through the resonance chamber 21 sequentially, through the passage 27 formed in the last resonance chamber 21 of the upper part sequentially passed through each of the lower resonance chamber 21, the inlet of the valve plate 24 ( 33 is introduced into the suction chamber 34, and is then supplied to the compression chamber of the compressor through the inlet 3a formed in the valve 8 of the compressor. When moving up and down, it passes through the valve 8 of the compressor and is discharged in a compressed state into the discharge chamber 36 formed in the valve plate 24 of the silencer 20. The discharged compressed air is discharged through the discharge hole 35 and the discharge. The transfer to the storage tank 7 through the pipe 12 connected to the ball 35 is performed continuously.

In the process of compressing the outside air by the compressor 100, the valve 8 is a check valve installed at the inlet 9 when the air sucked through the resonance chamber 21 of the silencer 20 flows into the compression chamber. 14 is open and the check valve 13 installed at the outlet 10 is closed, and the valve 8 of the compressor 100 is discharged so that the compressed air compressed in the compression chamber can be discharged to the outside. ) Check valve 13 is opened and the check valve 14 of the inlet (9) is cut off, at which time the noise generated by the check valve (14) 13 is opened and shut off Becomes The address sound generated by the check valves 14 and 13 is transmitted to the outside through the air passage, that is, the resonance chamber 21 of the silencer 20, to make the surrounding area noisy.

However, as a result of measuring the noise by attaching the silencer 20 of the present invention to the compressor 100, the mechanical noise of the compressor 100 itself, that is, the piston 4 in a state in which the valve 8 of the compressor 100 is removed. Noise was measured almost equal to the pure mechanical noise produced during this reciprocating motion. For reference, as a result of measuring the mechanical noise of the compressor in a state in which the valve 8 of the compressor was removed and the upper part of the piston 4 was opened, about 67Db was measured. After measuring the silencer 20 of the present invention, the compressor noise was measured. As a result, about 70Db was measured. This suggests that noise generated from the check valves 14 and 13 and others is significantly reduced by being absorbed or canceled while passing through the resonance chamber 21.

Next will be described the process by which the resonance chamber 21 reduced the noise in this way.

The loud noise generated by the check valves 14 and 13 of the compressor 100 proceeds in the opposite direction to the sucked air and sequentially passes through the resonance chamber 21 located at the lower portion of the sound absorbing plate 23. After passing through the resonance chamber 21 formed in the upper portion to exit the silencer 20. As such, the noise passing through the resonance chamber 21 is introduced into the first resonance chamber 21 at a predetermined angle of incidence angle θ. Since the resonance chamber 21 is formed in a circular shape, the incident noise is a resonance chamber. It hits and reflects on the side wall of 21 and is reflected at the same reflection angle θ 'as the incident angle θ as shown in FIGS. 16 to 17 around the center of the resonance chamber 21. It proceeds innumerable at. As the reflection proceeds, the first generated reflected wave and the later generated reflected wave cancel each other to reduce noise, and this phenomenon occurs continuously as the reflection continues, and the noise gradually decreases.

The reduced noise in the first resonance chamber 21 is introduced into the adjacent resonance chamber 21 through the incision 28 at a predetermined angle of incidence angle θ and reflected at the same angle. It passes through the last resonant chamber 21 and almost disappears.

In this way, the noise that proceeds sequentially through the resonance chamber 21 enters into the adjacent resonance chamber 21. At this time, the reflecting plate 22 is positioned in the cutout 28 of the incident resonance chamber 21. As a result, the reflection plate 22 is returned to the resonance chamber 21 before being incident again to be incident again, and further reduced while performing a myriad of reflections in the resonance chamber 21.

In addition, the silencer 20 of the present invention is because the resonance chamber 21 is formed in a circular shape to form a circle (30) consisting of a tangent, the trajectory is drawn while the noise is reflected, the ring installed at the position of the circle (30) Since the sound absorbent 32 of the shape absorbs the noise, the noise is significantly reduced.

In addition, since the side wall of the resonance chamber 21 in which the noise is reflected has a diffuse reflection surface 31 formed of an inclined surface as shown in FIG. 18, the reflected noise is diffusely reflected at various angles in the diffuse reflection surface 31 so that the reflection waves overlap each other. As the phenomenon increases, the noise decreases even more.

The silencer 20 of the present invention configured as described above provides a path through which the noise generated by the compressor 100 passes. Since the noise passing through the resonance chamber 21 is significantly reduced, the noise measurement value is described as described above. It was confirmed that it is about 70Db, which is close to the mechanical noise of the compressor itself.

Next will be described the compressor 100 using the silencer 20 of the present invention.

Compressor 100 to which the silencer 20 of the present invention is applied has a head 2 which sucks and compresses air as usual, and is mounted on the head 2 and sucked into the head 2, and the head 2 ), A manifold providing a flow path of air compressed and discharged, a pulley 6 connected to a connecting rod 5 so as to lift and lower the piston 4 accommodated in the cylinder of the head 2, and the pulley rotated. And a storage tank 7 for storing the compressed air discharged from the head 2.

As shown in the drawing, the head 2 of the compressor includes a piston 4 for performing compression in a compression chamber formed inside a cylinder, and a valve 8 for controlling the flow of air is installed and compressed above the compression chamber. The seal will be sealed. As described above, the valve 8 is provided with check valves 14 and 13 at the inlet 9 and the outlet 10 through which the air enters and exits, respectively.

In such a compressor, the compressor 100 of the present invention is characterized by replacing the manifold with the silencer 20 described above.

Here, the manifold has a plurality of resonance chambers 21 are in communication with each other on the upper and lower sides of the plate-shaped body to form a flow path, the first resonance chamber 21 of the upper surface is in communication with the inlet 26 of the body The last resonance chamber 21 of the upper surface is in communication with the first resonance chamber 21 of the lower surface so that the resonance chambers of the upper and lower sides are formed in the form of a single flow path; Attached to the lower surface of the silencer 23 to close the resonance chamber 21 in a state of confidentiality, the sound plate 23 in the position corresponding to the last resonance chamber 21 on the lower surface of the sound plate 23 An inlet 33 through which air flows in is passed through, and a lower surface of the body communicates with the inlet 33 to discharge air from the suction chamber 34 and the cylinder of the head 2 to supply air to the cylinder of the head 2. A valve plate 24 in which a compression chamber in which discharge holes 35 for discharging compressed air are formed is divided by partition walls 37; A cover 25 attached to an upper surface of the silencer 23 to close the resonance chamber 21 in a state of confidentiality; And the air introduced through the inlet 26 of the silencer 23 is sucked into the suction chamber 34 of the valve plate 24 by passing through the resonance chamber 21 forming the flow path, and the air in the compressor 100. The noise generated in the compressor 100 in the process of sucking the includes passing through the resonance chamber 21 in order to be reduced.

Here, the silencer 23, the valve plate 24, and the cover 25 constituting the manifold are the same as those of the silencer 20, and the description of the detailed structure is replaced by the structure of the silencer 20.

Compressor 100 of the present invention configured as described above is installed on the upper head (2) in which the piston (4) to perform the compression is reduced to reduce the noise generated when the head (2) to suck and compress the outside air Let's go.

This is because when the pulley 6 rotating by the driving of the motor rotates the connecting rod 5 of the piston 4, the piston 4 moves up and down as shown in FIGS. Suction is compressed into the compression chamber through the inlet of the valve 21 and the valve 8, and the compressed air is discharged through the outlet 10 of the valve 8 and the discharge hole 35 of the manifold to supply the pipe 12. It is stored in the storage tank (7) through.

In the process of compressing air in this way, when the air enters and exits the compression chamber, an address sound generated by the check valves 14 and 13 of the valve 8 of the compressor is formed in the resonance plate 23 of the sound absorbing plate 23 of the manifold ( When passing through 21) the manifold to reduce the noise passing through, since the noise reduction process has been described in detail in the muffler 20, a detailed description thereof will be omitted.

The silencer having the reflector of the present invention configured as described above has a resonance chamber formed in a circular shape so that the noise introduced into the resonance chamber is reflected at the same reflection angle as the incident angle, so that numerous reflections are generated in the resonance chamber. When the reflected waves overlap each other, the noise is reduced and an arc-shaped reflector is installed at the boundary of each resonance chamber to slow down the speed of the noise and increase the reduction effect. Also, the air absorbing agent and the diffuse reflection surface installed inside the resonance side are noise. By further reducing the noise effect is significantly improved compared to the conventional silencer.

This noise reduction effect has the advantage of protecting workers from noise pollution and improving the working environment.

In addition, since the silencer of the present invention reduces noise in the resonant chamber having a circular shape, since its structure is simple and can be manufactured in a small size, it is easy to handle and thus has the advantage of reducing manufacturing labor and cost.

Compressor using such a silencer is composed of a silencer, valve plate and cover having the same size as the manifold of the conventional compressor, with the original purpose of reducing the severe noise generated in the process of compressing the air to produce a compact compressor You will have the advantages.
