Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
In the description of the present invention, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "secured" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In a gas cleaning device of a tire inflation system as shown in fig. 1 to 3, an air inlet seat 1 is screwed with a cover body 3, and a first sealing ring 2 is arranged at the joint for ensuring tightness. An air inlet is arranged on one side of the air inlet seat, an air outlet is symmetrically arranged on the air inlet seat relative to the central axis of the air inlet seat, and the air inlet and the air outlet are not communicated. A vent hole communicated with the air outlet is arranged at the center of the air inlet seat, and the opening of the vent hole extends into the cavity of the cover body 3. The air inlet is isolated from the vent hole but communicates with the hood 3. The sleeve 10 with the filtering holes is arranged in the cover body 3, and the filtering holes can isolate particulate impurities in the air so as to ensure the air cleanliness. The inner cavity of the sleeve is communicated with the vent hole and isolates the vent hole from the inner cavity of the cover body 3. One end of the sleeve 10 is in contact connection with the air inlet seat 1, the other end of the sleeve 10 is connected with the end cover 9, and the end cover 9 and the sleeve 10 are fixed on one side, close to the cover body, of the air inlet seat 1 through screws.
An isolation cylinder 11 is arranged between the sleeve 10 and the cover body 3, a plurality of guide vanes are arranged on the outer surface of the isolation cylinder 11, the guide vanes enable air entering the cover body 3 to rotate along the tangential direction of the vanes, and water vapor, oil drops and other impurities mixed in the air are separated out under the action of centrifugal force.
An elastic isolation plate 4 is installed in the cover body 3, and the edge part of the elastic isolation plate 4 is contacted with the inner wall of the cover body, so that the inner diameter of the cover body 3 is gradually reduced from top to bottom. The lower part of the elastic isolation plate 4 is a needle-shaped body, the outer part of the needle-shaped body is sleeved in a drainage channel of the sealing seat 5, and the drainage channel protrudes out of the lower end of the cover body 3. A second sealing ring 6 is arranged between the sealing seat 5 and the inner wall of the cover body and between the needle-shaped body and the drainage channel. The sealing seat 5 is detachably connected with the cover body 3 through a screw 7.
Compressed air enters the cover body 3 from the air inlet, rotates at a high speed along the tangential direction of the guide vane, and vapor, oil drops and other impurities mixed in the air are separated out under the action of centrifugal force and thrown to the inner wall of the cover body 3 to flow downwards along the inner wall of the cover body. The cleaned gas after the removal of impurities is further filtered by the sleeve 10 to remove fine particle impurities, and the cleaned compressed air is discharged from the air outlet and enters the passage of the inflation system. The elastic isolation plate 4 divides the inner cavity of the cover body into an upper part and a lower part, when compressed air is discharged from the air outlet, the air pressure at the upper part of the elastic isolation plate 4 in the inner cavity of the cover body 3 is smaller than the air pressure at the lower part of the elastic isolation plate 4, the elastic isolation plate 4 moves upwards under the action of pressure difference, because the inner diameter at the upper part of the cover body 3 is larger than the inner diameter at the lower part, a gap is formed between the elastic isolation plate 4 and the inner wall of the cover body 3 in the upward moving process, water drops and oil drops flow into the lower space of the elastic isolation plate 4 from the gap, at the moment, the needle-shaped body is separated from the drainage channel, and the drainage channel is in an open state. When compressed air enters from the air inlet, the air pressure at the upper part of the elastic isolation plate 4 in the inner cavity of the cover body 3 is larger than the air pressure at the lower part of the elastic isolation plate 4, the elastic isolation plate 4 moves downwards under the action of pressure difference, the gap between the elastic isolation plate 4 and the cover body 3 is gradually reduced, water, oil and other liquid at the inner wall of the cover body are brought into the cavity at the lower part of the elastic isolation plate 4, and meanwhile, the air pressure in the cover body 3 is higher than the external atmospheric pressure in the downward operation process of the elastic isolation plate, so that the water, oil and other liquid impurities stored in the cavity at the lower part of the elastic isolation plate 4 are discharged into the atmosphere from the drainage channel, the needle body is gradually reset and matched with the drainage channel, and the drainage channel is gradually closed.
It should be noted that the gap between the elastic isolation plate 4 and the cover 3 in this device is not a gap in the conventional sense, and the gap distance only allows water and oil at the upper part of the elastic isolation plate 4 in the inner cavity of the cover 3 to enter the lower part of the elastic isolation plate 4 under the action of pressure, but water and oil in the lower space of the elastic isolation plate 4 will not recoil into the upper space.
It should be noted that the device is suitable for use in an inflatable system having a pressure in the range of 0.2-1.6 MPa.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
