Description

Technical Field

[0001] The utility model relates to the technical field of pressure swing adsorption oxygen production, and particularly relates to a pressure swing adsorption oxygen production device. Background Art

[0002] The pressure swing adsorption oxygen production device is mainly based on the principle of physical adsorption. By using a specific adsorbent (such as zeolite molecular sieve), the adsorption capacity of impurities such as nitrogen under pressurized conditions is much greater than that of oxygen, thereby realizing the separation and purification of oxygen. During the adsorption process, as the pressure changes, the adsorption amount of nitrogen by the adsorbent also changes, so as to continuously produce oxygen.

[0003] When producing oxygen, air needs to be conveyed into the adsorption tank. Since water dust and oil in the air during oxygen production will affect oxygen production, a filtering device is installed at the air inlet end of the adsorption tank to filter impurities. In order to make the replacement of the filtering device more convenient and enhance the air diversion effect and filtering effect, the Chinese utility model patent with the publication number "CN214495734U" discloses "a new type of energy-saving pressure swing adsorption oxygen production device". This device facilitates the installation and disassembly of the filter screen by setting a limiting rod, makes the disassembly and installation of the dehumidification box more convenient by setting a first groove, a second groove, a connecting rod and a fixing plate, and makes the dehumidification box more firmly fixed after installation by setting a telescopic rod and the spring. However, when replacing the filter screen of this device, the operation needs to be stopped and the handle needs to be rotated to replace the filter screen. Stopping the operation causes the oxygen production process to stop, affecting the continuous oxygen supply of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pressure swing adsorption oxygen production device to solve the problem that when replacing the filter screen, the operation needs to be stopped, resulting in the oxygen production process must stop, affecting the continuous oxygen supply of the device.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] A pressure swing adsorption oxygen production device includes a box body and a filtering component arranged in the box body. The filtering component includes a diversion cover, a filter plate and a mounting net. The diversion cover is fixedly connected to the inner wall of the box body, the mounting net is fixedly connected to the inner wall of the diversion cover, the filter plate is placed on the lower surface of the mounting net. Openings for the filter plate to penetrate into the box body are relatively arranged on both sides of the box body. A slideway capable of supporting the sliding of the filter plate is fixedly arranged on the inner wall of the box body. The slideway is at the same horizontal level as the opening and opposite to the opening. A spare track is movably connected to the outside of the box body, and the spare track is opposite to the opening of the box body.

[0007] The basic principle of the above technical solution is as follows: When it is necessary to replace the old filter plate in the box body, place the new filter plate on the spare track, push the new filter plate into the box body through the opening, the new filter plate is pushed into the slideway in the box body, and the new filter plate pushes the old filter plate in the box body out of the box body through another outlet. When the new filter plate is completely pushed into the box body, the old filter plate is pushed out of the box body.

[0008] The beneficial effect of the above technical solution is as follows: Compared with the existing situation where the device needs to stop working and rotate the handle to replace the filter screen, in this technical solution, the new filter plate pushes the old filter plate, and the old filter plate is pushed out of the box body from the slideway. During the process of alternately replacing the new and old filter plates, there is always a filter plate in the box body, and this device does not need to stop working, so that the oxygen production process continues without affecting the continuous oxygen supply of the device.

[0009] Further, the outside of the box body is hinged with a spare track through a rotating shaft, and a hook is hung on the upper part outside the box body. When the spare track is used up, the spare track can be rotated to fit the outer wall of the box body and then hooked by the hook, so that the spare track can be stored. On the one hand, it reduces the occupied space of the spare track, and on the other hand, it avoids the spare track being damaged and protects the spare track.

[0010] Further, a sealing block capable of blocking the opening is fixedly hung at the lower part of the box body through a hanging rope. After the old filter plate in the box body is replaced, take the sealing block to block the opening, so that the box body is in a closed state, which is more convenient for the box body to carry out adsorption oxygen production operation.

[0011] Further, there are two spare tracks in total, and the two spare tracks are symmetrically located on both sides of the box body respectively. One of the two symmetrical spare tracks is used to push the new filter plate, and the other is used to receive the old filter plate replaced from the box body.

[0012] Further, an air inlet pipe is fixedly provided on one side of the box body, an exhaust pipe is fixedly provided on the other side of the box body far away from the air inlet pipe, and a mesh cylinder is fixedly provided at the air inlet end of the air inlet pipe. Air is inhaled into the box body through the air inlet pipe, and the mesh cylinder first filters out the large impurities in the air.

[0013] Further, a handle is provided on the side of the filter plate. It is convenient to push the filter plate through the handle. Brief Description of the Drawings

An air inlet pipe 11 is fixedly provided on the lower left side of the box body 1, and an exhaust pipe 12 is fixedly provided on the upper right side of the box body 1 away from the air inlet pipe 11. A mesh cylinder 13 is fixedly provided at the air inlet end of the air inlet pipe 11.

[0021] The specific implementation process is as follows:

[0022] When it is necessary to replace the old filter plate in the box body 1, place the new filter plate on the spare track 8, adjust the handles 7 on the old filter plate and the new filter plate to be in a relative state through the spare tracks 8 on the left and right sides of the box body 1, and push the new filter plate into the box body 1 through the opening 5. The new filter plate is pushed into the slideway 6 in the box body 1, and the new filter plate pushes the old filter plate 3 in the box body 1 out of the box body 1 from another outlet. When the new filter plate is completely pushed into the box body 1, the old filter plate is pushed out of the box body 1. This device pushes the old filter plate through the new filter plate and pushes the old filter plate out of the box body 1 from the slideway 6. During the process of alternately replacing the old and new filter plates, there is always a filter plate in the box body 1. This device does not need to stop working, so that the oxygen generation process continues and does not affect the continuous oxygen supply of the device.
