[0002] Pressure swing adsorption is a gas separation technology, mainly used for the production and purification of industrial gases, especially in occasions where high-purity gases are required, such as oxygen, nitrogen, etc. It utilizes the selective adsorption characteristics of solid adsorbents to achieve gas separation by periodically changing the pressure of the adsorption bed. Gas filtration is a separation technology aimed at removing solid particles, liquid droplets, microorganisms or certain gas impurities from the gas stream to purify the gas or protect downstream equipment from pollution. Silencing refers to the process of reducing or eliminating noise through various technical means.

[0003] For existing intake air filtering silencers, the filter and the silencer are generally two independent devices, and the installation steps are relatively complex. Moreover, when they are single devices, the device volume is generally large, the filtering effect is not good, the noise reduction effect is not good, and the gas volume required by the pressure swing adsorption device is large.

[0018] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but do not limit the present utility model.

[0019] A pressure swing adsorption oxygen production air inlet filtering and silencing device, as Figures 1 - 3As shown in the figure, it includes a mounting plate 1, a support frame 2, a connecting pipe 3, a flange 4, an intake pipe 5, a filter screen 6, a sound-absorbing block 7, a rotating ring 8, a handle 9, a clamping member 10 and a limiting block 11. On the front side of the left and right parts of the mounting plate 1, support frames 2 are connected respectively. In the middle of the mounting plate 1, a connecting pipe 3 is connected. At the rear side of the connecting pipe 3, a flange 4 is connected, which is convenient for connecting to an external pipeline. At the front side of the connecting pipe 3, an intake pipe 5 is connected. The intake pipe 5 is connected to the mounting plate 1. The diameter of the left part of the intake pipe 5 is larger than that of the right part. Inside the intake pipe 5, a sound-absorbing block 7 is connected. At the front part of the intake pipe 5, a rotating ring 8 is rotatably connected. On the outer side of the rotating ring 8, four handles 9 are connected, which is convenient for holding and rotating the rotating ring 8. The handles 9 are evenly distributed along the outer side of the rotating ring 8. On the rotating ring 8, four limiting blocks 11 are evenly distributed in a circular pattern. On each of the limiting blocks 11, a clamping member 10 is clamped. Between the clamping members 10, a filter screen 6 is connected. The filter screen 6 is in contact with the intake pipe 5.

[0020] When pressure swing adsorption needs to suck gas, this device can be used. Bring this device to the place where gas needs to be sucked, install this device through the mounting plate 1, then connect to an external pipeline through the flange 4, and then rotate the rotating ring 8 through the handle 9, thereby driving the limiting block 11 to rotate, so that the clamping member 10 on the filter screen 6 contacts the rotating ring 8, and then rotate the rotating ring 8 in the reverse direction, so that the limiting block 11 rotates in the reverse direction and is clamped with the clamping member 10, thus enabling the installation of the filter screen 6. The operation is simple, which is convenient for the replacement, loading and unloading of the filter screen 6, increases the service life of the equipment, and reduces the maintenance cost. Then make the gas enter the intake pipe 5 and then into the connecting pipe 3. The diameter of the left part of the intake pipe 5 is larger than that of the right part. When it is transported to other pipelines, when the gas enters the intake pipe 5, the gas will pass through the filter screen 6. The gas is filtered through the filter screen 6, increasing the gas cleanliness and reducing impurities such as dust and dirt. Then, the sound-absorbing block 7 is used to perform sound-absorbing treatment on the noise generated during air flow, so that the gas can be filtered and silenced at the same time, realizing the integration of filtration and silencing, occupying a small space, having a large air intake, good sound-absorbing effect, and improving the installation efficiency. When the filter screen 6 needs to be replaced, rotate the rotating ring 8 through the handle 9 to make the limiting block 11 disengage from the clamping member 10, then remove the filter screen 6, and then replace the filter.
