Description

field

[0002] The present invention relates to an oxygen generator for preparing gas from air. background

[0004] The existing method of producing oxygen is to utilize the different boiling points of oxygen and nitrogen to separate the oxygen by liquefying air and evaporating and condensing it multiple times. This method has high output, but requires large equipment and is costly. Summary of the invention

[0005] The problem to be solved by the present invention is: adopting a method to prepare oxygen with low cost.

[0006] In order to solve the above problems, the working principle of the present invention is as follows: air with a certain pressure is sent into a hollow separation tube with a certain curvature, and a partition is inserted into the outlet part of the tube; at this time, the air entering the separation tube is subjected to the centrifugal force, and since the mass of oxygen is greater than that of nitrogen, the oxygen is on the outside of the separation tube, while the nitrogen is on the inside of the separation tube; the oxygen in the separation tube is allowed to flow out from the outside of the partition, while the nitrogen is allowed to flow out from the inside; the outflowing oxygen is sent to a desired place through an air outlet pipe, thereby obtaining oxygen.

[0007] After adopting the above method, since oxygen can be obtained by simply pressurizing the air and sending it into the separation tube, the equipment cost is low and the power consumption is low, so the overall cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 4 The first embodiment of an oxygen concentrator of the present invention is attached Figure 3 Section view. Example

[0012] In the attached Figure 1 To Attachment Figure 4In the first embodiment shown, an oxygen concentrator of the present invention comprises a power part (1), a separation part (2) and a support part (3), wherein the power part (1) comprises a fan (1-1), a connecting pipe (1-2), a sealing ring (1-3), a bolt (1-4) and a nut (1-5); the separation part (2) comprises a separation pipe (2-1), a partition (2-2), an air outlet pipe (2-3) and a support shaft (2-4); and the support part (3) comprises a base frame (3-1), a support frame (3-2), a washer (3-3), a nut (3-4), a fixing bolt (3-5) and a fixing nut (3-6). The fan (1-1) is fixed to the base frame (3-1) by bolts (1-4) and nuts (1-5); one end of the connecting pipe (1-2) is connected to the fan (1-1) by bolts (1-4) and nuts (1-5); the other end is connected to the separation pipe (2-1); a sealing ring (1-3) is placed in the middle; the separation pipe (2-1) is sleeved on the support shaft (2-4); the support frame (3-2) is sleeved on both ends of the support shaft (2-4); the washer (3-3) is sleeved on the support shaft (2-4); the nut (3-4) is screwed on; the support frame (3-2) is installed on the base frame (3-1) by fixing bolts (3-5) and fixing nuts (3-6); the partition plate (2-2) is inserted into the outlet end of the separation pipe (2-1) and welded to the wall; the air outlet pipe (2-3) is welded to the partition plate (2-2) and the separation pipe (2-1). When in use, the fan (1-1) is powered on, the fan (1-1) enters, and flows out along the outlet of the separation tube (2-1). In this process, because the separation tube (2-1) is wound in a circular shape, the oxygen and nitrogen in the air are affected by centrifugal force during the flow process. Because oxygen is heavier than nitrogen, oxygen will gradually move to the outside of the separation tube (2-1) under the action of centrifugal force, while nitrogen will be inside; and the gas in the air outlet pipe (2-3) connected to the outside of the separation tube (2-1) is oxygen, while nitrogen flows out from the outlet inside the separation tube (2-1), and the air outlet pipe (2-3) leads to a desired place.

[0013] The present invention is not limited to the above forms. When the separation tube (2-1) has multiple layers; when there is no support in the separation tube (2-1); when the cross section of the separation tube (2-1) is made into other shapes, it is also within the scope of the present invention.

[0014] When the gas outlet pipe (2-3) is connected to the other side of the partition (2-2), nitrogen can be obtained.

[0015] The present invention can be used not only for producing oxygen, but also for producing nitrogen; and can also be used for producing both.
