Description

Technical Field

[0002] Air compressors, as devices used to produce compressed air, are widely used in industries such as steel, electronics, chemicals, automobiles, semiconductors, and power. During operation, air compressors periodically discharge condensate. This condensate contains a large amount of high-pressure compressed air and has a high pressure (up to 8.2 bar). Therefore, directly discharging the condensate to a ground-level containment dam causes problems such as splashing and significant noise. Utility Model Content

[0025] like Figure 1 and Figure 2 As shown, the auxiliary drainage device 100 provided in this embodiment of the present invention includes a housing 110 and a noise reduction component 120. The housing 110 is a hollow structure with an inner cavity 111. The housing 110 is also provided with a liquid inlet channel 112 and a liquid outlet channel 113 communicating with the inner cavity 111. The liquid inlet channel 112 is higher than the liquid outlet channel 113. The noise reduction component 120 is disposed in the inner cavity 111. The noise reduction component 120 is a flexible structure, and a mesh (not shown in the figure) is formed on the noise reduction component 120.

[0026] The auxiliary drainage device 100 is used to assist in draining the air compressor (not shown in the figure). In use, the inlet channel 112 on the housing 110 is connected to the outlet of the air compressor via a pipe. When the air compressor drains, the high-pressure condensate discharged from the outlet first enters the inner cavity 111 of the housing 110 along the pipe and the inlet channel 112, and then exits through the drainage channel 113. After entering the inner cavity 111, the high-pressure condensate releases at least some gas to reduce pressure. When the depressurized condensate exits through the drainage channel 113, it effectively reduces splashing and noise caused by excessive pressure. Furthermore, the noise reduction component 120 can reduce the noise generated by the high-pressure condensate and / or absorb the noise generated by the condensate. In other words, the application of the auxiliary drainage device 100 can effectively solve the splashing and noise problems during air compressor drainage in the prior art.

[0027] The structure of the auxiliary drainage device 100 will be further described below.

[0028] The housing 110 may include a bottom wall 114, side walls 115, and a top wall, wherein the bottom wall 114, the side walls 115, and the top wall are sequentially connected and enclose the inner cavity 111. It can be understood that in some examples, the housing 110 has a cubic structure, thus the number of side walls 115 is four; in other examples, the housing 110 may have a cylindrical structure, thus the side walls 115 are curved surfaces.

[0029] The drainage channel 113 can be located on the bottom wall 114, allowing the housing 110 to be placed directly above the ground dike. Condensate, after pressure reduction within the housing 110, can be directly discharged into the ground dike through the drainage channel 113 under gravity. The inlet channel 112 can be located on the side wall 115 or the top wall, but is generally located on the side wall 115. This is because the top wall preferably also forms at least partially an openable and closable cover to facilitate maintenance of the interior of the housing 110 and to allow for replacement of the noise reduction component 120 as needed.

[0030] Preferably, the bottom wall 114 and the side walls 115 are made of at least a metal material to make them robust and reliable, thereby giving the housing 110 a longer service life. Furthermore, the top wall 115 is also made of a metal material. Optional metal materials include, for example, stainless steel, more specifically, SUS304 stainless steel. Additionally, the thickness of the bottom wall 114, the side walls 115, and the top wall can be between 1.5 mm and 3 mm, for example, around 2 mm.

[0031] In some examples, the noise reduction component 120 includes a first noise reduction structure 121 and a second noise reduction structure 122. The cooperation of the first noise reduction structure 121 and the second noise reduction structure 122 effectively reduces the noise generated by high-pressure condensate in the inner cavity 111 of the housing 110.

[0032] The first noise reduction structure 121 may include multiple material components, which are stacked to form a loose three-dimensional shape. Alternatively, the first noise reduction structure 121 may include a long strip of material component, which is rolled or stacked to form a loose three-dimensional shape. The three-dimensional first noise reduction structure 121 is placed directly in the inner cavity 111, preferably facing the path of the liquid entering the inner cavity 111 from the liquid inlet channel 113. In this way, when the auxiliary drainage device 100 is used in conjunction with the air compressor, the high-pressure condensate entering the inner cavity 111 can directly impact the first noise reduction structure 121, reducing impact noise. Moreover, the splashing droplets generated by the impact of the condensate further impact the first noise reduction structure 121 and / or the second noise reduction structure, resulting in relatively low impact noise.

[0033] In practice, the material component may include at least one of a scouring pad, thermal insulation cotton, and sound insulation cotton. It is understood that when the material component includes a scouring pad, it also has the advantage of being inexpensive and readily available; when the material component includes thermal insulation cotton or sound insulation cotton, the first noise reduction structure 121 can better absorb the noise generated by condensate. Furthermore, it should be understood that the arrangement of the first noise reduction structure 121 should not obstruct the discharge of condensate from the drain channel 113.

[0034] The second noise reduction structure 122 is attached to at least a portion of the inner surface of the enclosure 110, for example, to the inner surface of all the side walls 115 of the enclosure 110, or to the inner surface of the bottom wall 114, or to all the inner surfaces of the enclosure 110. The provision of the second noise reduction structure 122 reduces the possibility of significant impact noise caused by condensate directly impacting the inner surface of the enclosure 110. In particular, when the second structure 122 is attached to all the inner surfaces of the enclosure 110, there is no impact of condensate on the inner surface of the enclosure 110, which further reduces the impact noise generated by condensate.

[0035] It should be understood that the second noise reduction structure 122 should not obstruct the condensate from entering the inner cavity 111 through the liquid inlet channel 112, nor should it obstruct the condensate from being discharged through the liquid outlet channel 113.

[0036] The second noise reduction structure 122 is made of materials such as thermal insulation cotton or sound insulation cotton. In this way, the second noise reduction structure 122 can better absorb the noise generated by condensation, thereby further reducing noise pollution.

[0037] The second noise reduction structure 122 should have an appropriate thickness. If the thickness of the second noise reduction structure 122 is too small, its sound absorption effect will be limited; if the thickness of the second noise reduction structure 122 is too large, it will be wasteful. Optionally, the thickness of the second noise reduction structure 122 can be selected in the range of 20mm to 50mm.

[0038] In other examples, the noise reduction component 120 may include only the first noise reduction structure 121, or only the second noise reduction structure 122.

[0039] Furthermore, this utility model also provides an air compressor assembly, which includes an air compressor and an auxiliary drainage device 100 as described above. The inlet channel 112 on the housing 110 of the auxiliary drainage device 100 is connected to the water outlet of the air compressor via a pipe.

[0040] It should be noted that the specific structure of the air compressor can be referred to in the prior art, and it is not related to the improvement points of this utility model, so it will not be described here.

[0041] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and variations.
