Description

Technical Field

[0001] The utility model relates to the technical field of steam-water separators, in particular to a steam-water separator for a molecular sieve oxygen generator. Background Art

[0002] Molecular sieve oxygen concentrators are common medical devices in hospitals, producing oxygen at a specific concentration. They typically utilize a pressurized adsorption and atmospheric pressure desorption (HP) method, with two adsorption towers each performing the same cycle to achieve continuous air supply. The entire system is fully automatically controlled by a single-chip microcomputer. However, when using molecular sieve oxygen concentrators, the incoming air must be moisture-free, so a dehumidifier is used to dry the air.

[0003] After drying the air, most existing steam-water separators directly discharge it or use it in the next step. However, after the air is dried, there is no good humidity detection. Once the air drying does not meet the standards, it is used directly, which will affect the oxygen production effect of the molecular sieve oxygen generator, resulting in certain limitations in the use of the device. Utility Model Content

[0004] The main purpose of the utility model is to provide a steam-water separator for a molecular sieve oxygen generator, which can effectively solve the problem that the steam-water separator cannot perform humidity detection well after drying the air.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A steam-water separator for a molecular sieve oxygen concentrator comprises a support base, a steam-water separator housing is mounted on the left upper end of the support base, an air inlet is mounted on the lower left end of the steam-water separator housing, a sealing cover is mounted on the upper end of the steam-water separator housing, a No. 1 connecting pipe is mounted on the upper right end of the steam-water separator housing, a storage box is mounted on the right upper end of the support base, and a detection device is mounted on the lower front end of the storage box.

[0007] Preferably, a support frame is mounted within the water-steam separator housing, an adsorption pad is mounted on the upper end of the support frame, a drain port is mounted in the middle portion of the lower end of the water-steam separator housing, an opening is formed at the left portion of the upper end of the support frame, the drain port is located within the opening, and a connecting groove is formed at the upper end of the air inlet. External air is introduced into the water-steam separator housing through the air inlet, whereupon the air passes through the adsorption pad to adsorb and filter moisture within the housing. The dried air then enters the storage box through the first and second connecting pipes for storage. Furthermore, by opening the sealing cover, the adsorption pad can be directly removed because it is placed on the support frame, thereby facilitating replacement and cleaning of the adsorption pad.

[0008] Preferably, the storage box is provided with a No. 2 fan installed at the lower right end of the storage box, a No. 1 fan installed at the upper end of the storage box, an extraction pipe installed between the right end of the No. 1 fan and the storage box, a return pipe installed at the left end of the No. 1 fan, and the return pipe is connected to the air inlet via a connecting groove, and a No. 2 connecting pipe is installed at the upper left end of the storage box. The No. 1 fan is activated by a controller, and the extraction pipe on the No. 1 fan extracts the air in the storage box and sends it into the air inlet through the return pipe, thereby re-drying the air. After the humidity sensor detects that the air meets the standard, the No. 2 fan is activated by the controller to discharge the air in the storage box into the molecular sieve oxygen concentrator.

[0009] Preferably, the detection device includes a controller, a display screen is installed at the front end of the controller, a humidity sensor is installed at the right end of the controller, and the humidity sensor is located in the storage box. The humidity of the dried air is detected by the humidity sensor, and the humidity information is transmitted to the controller.

[0010] Preferably, the No. 1 connecting pipe and the No. 2 connecting pipe are of the same height and are flange-connected.

[0011] Preferably, the controller is electrically connected to both the No. 1 and No. 2 wind turbines.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Introduce external air into the steam-water separator shell through the air inlet. At this time, the air passes through the adsorption pad to absorb and filter the moisture inside. The dried air enters the storage box through the No. 1 connecting pipe and the No. 2 connecting pipe for storage. At this time, the humidity of the dried air is detected by the humidity sensor on the detection device, and the humidity information is transmitted to the controller. When the air dryness does not meet the standard, the No. 1 fan is started by the controller, and the extraction pipe on the No. 1 fan extracts the air in the storage box and sends it into the air inlet through the return pipe, so as to dry the air again. After the humidity sensor detects that it meets the standard, the No. 2 fan is started by the controller to discharge the air in the storage box into the molecular sieve oxygen generator.

[0014] 2. When the steam-water separator has been used for a long time, by opening the sealing cover, the adsorption pad is placed on the support frame, so the adsorption pad can be directly taken out, which makes it easier to replace and clean the adsorption pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-4As shown, a steam-water separator of a molecular sieve oxygen concentrator includes a support base 1, a steam-water separator housing 2 is installed on the left upper end of the support base 1, an air inlet 6 is installed on the lower left end of the steam-water separator housing 2, a sealing cover 5 is installed on the upper end of the steam-water separator housing 2, a No. 1 connecting pipe 7 is installed on the upper right end of the steam-water separator housing 2, a storage box 3 is installed on the right upper end of the support base 1, and a detection device 4 is installed on the lower front end of the storage box 3.

[0024] A support frame 20 is mounted within the separator housing 2. An adsorption pad 21 is mounted on the upper end of the support frame 20. A drain port 23 is mounted in the middle portion of the lower end of the separator housing 2. An opening 24 is formed on the left side of the upper end of the support base 1. The drain port 23 is located within the opening 24. A connecting slot 22 is formed at the upper end of the air inlet 6. External air is introduced into the separator housing 2 through the air inlet 6. At this point, the air passes through the adsorption pad 21, where it absorbs and filters the moisture within. The dried air then flows through the No. 1 connecting pipe 7 and the No. 2 connecting pipe 33 and enters the storage box 3 for storage. Furthermore, by opening the sealing cover 5, the adsorption pad 21, which is placed on the support frame 20, can be directly removed, making it easier to replace and clean the adsorption pad 21.

[0025] The storage box 3 has a No. 2 fan 34 installed at the lower right end of the storage box 3, and a No. 1 fan 30 installed at the upper end of the storage box 3. An extraction pipe 31 is installed between the right end of the No. 1 fan 30 and the storage box 3. A return pipe 32 is installed at the left end of the No. 1 fan 30, and the return pipe 32 is connected to the air inlet 6 through the connecting groove 22. A No. 2 connecting pipe 33 is installed at the upper left end of the storage box 3. The No. 1 connecting pipe 7 is at the same height as the No. 2 connecting pipe 33 and is flange-connected. When the air dryness does not meet the standard, the No. 1 fan 30 is activated by the controller 40, and the extraction pipe 31 on the No. 1 fan 30 further extracts the air from the storage box 3 and sends it to the air inlet 6 through the return pipe 32, thereby re-drying the air. After the humidity sensor 41 detects that it meets the standard, the No. 2 fan 34 is activated by the controller 40 to discharge the air in the storage box 3 into the molecular sieve oxygen generator.

[0026] The detection device 4 includes a controller 40 with a display screen 42 mounted on the front end. A humidity sensor 41 is mounted on the right end of the controller 40 and is located within the storage box 3. The controller 40 is electrically connected to both the first and second fans 30, 34. The humidity sensor 41 detects the humidity of the dried air and transmits the humidity information to the controller 40.

[0027] It should be noted that the present invention is a water-gas separator for a molecular sieve oxygen concentrator. External air is introduced into the water-gas separator housing 2 through the air inlet 6. At this time, the air passes through the adsorption pad 21 to absorb and filter the moisture inside. The dried air passes through the No. 1 connecting pipe 7 and the No. 2 connecting pipe 33 and enters the storage box 3 for storage. At this time, the humidity of the dried air is detected by the humidity sensor 41 on the detection device 4, and the humidity information is transmitted to the controller 40. When the air dryness does not meet the standard, the controller 40 starts the No. 1 connecting pipe 7 and the No. 2 connecting pipe 33. The fan 30 and the extraction pipe 31 on the No. 1 fan 30 extract the air in the storage box 3 and send it into the air inlet 6 through the return pipe 32, so as to re-dry the air until the humidity sensor 41 detects that it meets the standard. The controller 40 starts the No. 2 fan 34 to discharge the air in the storage box 3 into the molecular sieve oxygen generator. When the steam-water separator has been used for a long time, by opening the sealing cover 5, the adsorption pad 21 is placed on the support frame 20, so the adsorption pad 21 can be directly taken out, which facilitates the replacement and cleaning of the adsorption pad 21.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
