Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to an exhaust device for an air compressor. Background Art

[0002] Air compressor is the abbreviation of air compressor, which is a device used to compress gas; air compressor is similar to water pump in structure; most air compressors are reciprocating piston type, rotating blades or rotating screws, among which screw air compressor is a rotary positive displacement compressor, in which two rotors with helical gears mesh with each other, so that the volume of the two rotors meshing from large to small, thereby compressing and discharging the gas; the exhaust device of the air compressor is its important component, and the effect of the exhaust device directly affects the working effect of the air compressor. The existing air compressor exhaust device will generate loud noise when exhausting because the airflow is compressed and passes rapidly through a smaller exhaust hole, thereby causing noise pollution.

[0003] For example, a Chinese patent with publication number CN219509778U discloses an air compressor exhaust device, comprising: an air compressor body, the surface of which is connected to an exhaust pipe; a noise reduction mechanism, wherein the noise reduction mechanism for reducing the noise of the air compressor during exhaust is arranged on the surface of the air compressor body; a filter in the device filters the incoming air, so that particulate impurities in the air are blocked, and particulate impurities in the air are prevented from colliding with the air in the noise reduction box, thereby causing excessive wind noise. Because the two sound-absorbing panels and sound-absorbing cotton in each group are in an eight-shaped shape, they are used to reduce the flow rate of wind in the exhaust pipe to the noise reduction box. The sound-absorbing panels and sound-absorbing cotton interact with each other to absorb most of the wind noise in the noise reduction box, and the air is discharged through the slow flow frame in turn, ensuring that the air compressor exhaust device does not generate loud noise when exhausting, avoiding noise pollution, and ensuring the comfort of the workers' working environment.

[0004] This patent has some shortcomings when used, such as: the device in this patent does not separate water and oil from the gas discharged by the air compressor. Since the gas compressed by the air compressor contains more liquids such as water and oil, if the compressed gas with water and oil directly enters the noise reduction box, it will cause the sound-absorbing board and the silencer to absorb more water, thereby reducing its own noise reduction effect; in addition, when the sound-absorbing board and the silencer need to be replaced due to absorbing excessive water, the device in this patent is not convenient for replacing them. In view of this, we propose an air compressor exhaust device. Utility Model Content

[0042] The liquefaction bucket 10 is fixedly installed in the inner cavity of the air compressor body 1 and is located directly above the guide ring 9. A cooling box 12 is arranged above the liquefaction bucket 10, and the lower surface of the cooling box 12 is in contact with the upper surface of the liquefaction bucket 10. An air guide pipe 13 is fixed on the top of the liquefaction bucket 10, and the other end of the air guide pipe 13 passes through the inner top surface of the drainage box 4 and extends to the outside.

[0043] The noise reduction box 20 is fixedly mounted at one end of the air duct 13 away from the drainage box 4. An opening is provided at the front side of the noise reduction box 20. A baffle 25 is slidably mounted at the front opening of the noise reduction box 20. A through groove is provided at the upper surface of the noise reduction box 20 near the left front side.

[0044] A noise reduction component, which is arranged in the inner cavity of the noise reduction box 20 and is used to reduce the noise of the gas discharged from the air compressor body 1;

[0045] A limit assembly, which is disposed in a through slot on the noise reduction box 20 and is used to constrain and limit the baffle 25;

[0046] In this embodiment, the noise reduction component includes:

[0047] From left to right, a dustproof net 21, a sound-absorbing board 22 and a sound-absorbing cotton 23 are arranged. The dustproof net 21, the sound-absorbing board 22 and the sound-absorbing cotton 23 are movably installed in the inner cavity of the noise reduction box 20. A plurality of evenly distributed resonance rods 24 are arranged in the noise reduction box 20 and on the right side of the sound-absorbing cotton 23. The resonance rods 24 are fixedly connected to the inner wall of the noise reduction box 20.

[0048] In this embodiment, the limiting component includes:

[0049] A fixing block 26 is fixedly installed in a through groove on the noise reduction box 20. A slide groove 27 is provided in the fixing block 26. A paddle 28 is slidably installed in the slide groove 27. A spring 29 is fixed between the paddle 28 and the inner wall of the slide groove 27. A limiting rod 30 is fixed to the side of the paddle 28 facing the baffle 25. A limiting hole 31 matched with the limiting rod 30 is provided on the baffle 25. The limiting rod 30 is plugged into the limiting hole 31. The top of the paddle 28 passes through the inner top surface of the slide groove 27 and extends to the outside.

[0050] Among them, the working principle of this device is as follows:

[0051] The air compressor body 1 discharges gas to the outside through the air outlet pipe 2, and the gas enters the bottom of the inner cavity of the drainage box 4 through the connecting pipe 3, and a plurality of protective mesh plates 19 are started to reheat the gas. The gas moves upward and moves toward the outer circumference of the storage bucket 7 along the slope of the lower surface of the storage bucket 7, and finally enters the upper part of the drainage box 4 through the air vent 8. Due to the effect of the cooling box 12, the temperature of the upper inner cavity of the drainage box 4 is relatively low. After the water vapor in the high-temperature gas enters the lower surface of the liquefaction bucket 10, it is quickly liquefied when it encounters cold, and begins to condense into liquid water droplets on the lower surface of the liquefaction bucket 10, and drips downward along the lower surface of the liquefaction bucket 10 and a plurality of condensation columns 11. A part of the water droplets drips on the upper surface of the guide ring 9, and then falls along the inclined surface of the guide ring 9 and falls into the inner cavity of the storage bucket 7, and another part of the water droplets directly drip into the inner cavity of the storage bucket 7. When it is necessary to discharge the liquid accumulated in the storage bucket 7, the operator opens the valve 17, and the liquid can be discharged to the outside along the drain pipe 16;

[0052] The dehumidified and cooled gas enters the noise reduction box 20 along the air duct 13, and passes through the dustproof net 21, the sound absorbing board 22 and the sound absorbing cotton 23 in sequence, wherein the impurities in the gas are filtered by the dustproof net 21, and the noise generated by the gas during the transportation process is absorbed and weakened by the sound absorbing board 22 and the sound absorbing cotton 23. Then, when the remaining noise passes through the multiple resonance rods 24, the resonance rods 24 are triggered to vibrate, and the resonance rods 24 absorb and offset the remaining sound wave capacity in the noise, so that the noise of the gas finally discharged from the noise reduction box 20 is low;

[0053] When it is necessary to replace or maintain the parts in the noise reduction box 20, the operator pushes the paddle 28 to the rear side, and the paddle 28 moves inward and squeezes the spring 29, and at the same time drives the limit rod 30 to retract into the slide groove 27. At this time, the limit rod 30 is no longer plugged into the limit hole 31 on the baffle 25. The operator slides the baffle 25 to the right to open the inner cavity of the noise reduction box 20. Then the operator can replace and maintain the dustproof net 21, the sound absorbing board 22 and the sound absorbing cotton 23 according to actual needs;

[0054] When the cooling liquid needs to be added to the cooling box 12 , the operator pulls the plug 15 upwards and injects the cooling liquid into the inner cavity of the cooling box 12 through the injection pipe 14 .

[0055] By setting up the drainage box 4, the coolant in the cooling box 12 is used to liquefy the gas entering the liquefaction bucket 10, so that the water vapor in the high-temperature gas can be quickly liquefied and condensed on the lower surface of the liquefaction bucket 10. The water droplets are heavier than air, so they cannot enter the noise reduction box 20 along the air guide pipe 13 and have an adverse effect on the dustproof net 21, the sound absorbing board 22 and the sound absorbing cotton 23, which greatly increases the service life of the dustproof net 21, the sound absorbing board 22 and the sound absorbing cotton 23. By setting up the electric heating pipe 18, the gas entering the bottom of the drainage box 4 can be further Heating can improve the liquefaction effect of the gas below the liquefaction bucket 10, so that the water vapor in the gas can be removed more fully; by setting a limit assembly, the limit rod 30 and the limit hole 31 are engaged to realize the constraint of the baffle 25. When it is necessary to open the inner cavity of the noise reduction box 20 and maintain and replace multiple parts in the noise reduction box 20, the operator only needs to push the paddle 28 to the rear side. The device has a simple structure and is easy to operate. It saves the time required for installation and disassembly for the operator to repair the parts in the noise reduction box 20 in the later stage.
