Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment technology, specifically an energy-saving modular oxygen generator. Background Technology

[0002] An oxygen generator is a device that uses air as a raw material and employs pressure swing adsorption to separate oxygen and nitrogen from the air in order to obtain a high concentration of oxygen. It is widely used in the field of industrial oxygen production.

[0023] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples:

[0024] This utility model discloses an energy-saving modular oxygen generator, such as Figures 1-4 As shown, the oxygen concentrator includes an electrical control component 1, an air handling module 2, and an oxygen generation component 3. These three components are respectively housed within a first housing 4, a second housing 5, and a third housing 6. The first housing 4, second housing 5, and third housing 6 are sequentially connected along the height of the oxygen concentrator, arranged from low to high. The oxygen generation component 3 includes several oxygen tanks 31 and a gas transmission structure 32. Several insertion ports 61 are provided on both sides of the third housing 6. The oxygen tanks 31 are inserted into and fixed within the third housing 6 through the insertion ports 61. The transmission structure 32 is distributed inside the bottom and top of the third housing 6 outside the oxygen generator 31. The air inlet at the bottom of the oxygen generator 31 and the air outlet at the top of the oxygen generator 31 are respectively connected to the portions of the gas transmission structure 32 distributed at the bottom and top of the third housing 6. A top cover 7 is fixedly connected to the top of the third housing 6. At least one connector 8 is provided at the top of the top cover 7. The connector 8 is connected to the portions of the gas transmission structure 32 distributed at the top of the third housing 6. A control panel 9 is provided on one side wall of the third housing 6. The control panel 9 is electrically connected to the electrical control component 1, the air handling module 2, and the oxygen generator 3.

[0025] It should be noted that users can input control commands on the control panel 9. These commands are transmitted to the electrical control component 1, which then controls the oxygen generator's operation. Specifically, the electrical control component 1 controls the air handling module 2 and the oxygen generating component 3. The air handling module 2 processes the air and generates high-pressure air, which is then transmitted to the oxygen tank 31 via the gas transmission structure 32 in the oxygen generating component 3 to produce oxygen. The oxygen obtained in the oxygen tank 31 using the PSA oxygen generation process is then transmitted to connector 8 via the gas transmission structure 32. Connector 8 can be connected to a pipe to transmit the produced oxygen to a gas storage tank (not shown in the figure), thus enabling the oxygen generator to produce oxygen. The oxygen generator using the PSA oxygen generation process has a low air consumption ratio and high oxygen production efficiency. The multiple oxygen generators in the oxygen generating component 3... The tank 31 can work with the gas transmission structure 32 to simultaneously produce oxygen, thereby producing oxygen in a short time. Alternatively, the gas transmission structure 32 can control the air handling module 2 to transmit air raw materials to the oxygen generating component 3 and output oxygen to the connector 8, achieving precise control over the oxygen production volume and time of the oxygen generator, making the oxygen generator more flexible in use. Moreover, the electrical control component 1, the air handling module 2, and the oxygen generating component 3 are respectively housed in the first housing 4, the second housing 5, and the third housing 6. The three housings are connected to form the overall outer shell structure of the oxygen generator, and these three parts are independently distributed at different heights. When maintaining the oxygen generator, the faulty component can be accurately located at the corresponding position in these three parts, facilitating maintenance. At the same time, the modular component design makes the oxygen generator more compact and smaller in size.

[0026] It needs to be further explained that, such as Figures 3-5 As shown, the gas transmission structure 32 includes a first outer shell 321, a first gas delivery pipe 322, a first metering pump 323, and a first main unit 324. The first outer shell 321 is fixedly connected to the wall at the bottom of the middle part of the third shell 6. One end of the first gas delivery pipe 322 is connected to the output end of the air handling module 2. The first metering pump 323 is fixedly connected to the wall outside the oxygen generator 31 of the first outer shell 321. The other end of the first gas delivery pipe 322 passes through the third shell 6 and is connected to the first metering pump 323 through a branch. The output end of the first metering pump 323 is connected to the air inlet at the bottom of the oxygen generator 31 through a pipe. The first main unit 324 is fixedly connected above the first outer shell 321 and is electrically connected to the electrical control component 1 and the first metering pump 323, respectively.

[0027] During oxygen production, the user controls the first metering pump 323 corresponding to the oxygen generating tank 31 at different locations in the third housing 6 by inputting command signals on the control panel 9. After the command signal is transmitted to the electrical control component 1, the electrical control component 1 generates a corresponding control command based on the command signal and transmits it to the first host 324. The first host 324 controls the first metering pump 323 at the designated location to pump the high-pressure air in the first gas delivery pipe 322 into the corresponding oxygen generating tank 31, thereby realizing the oxygen production operation of a single oxygen generating tank 31 or multiple oxygen generating tanks 31 to meet different oxygen production needs; and the first The metering pump 323 can calculate the amount of high-pressure air input into the oxygen generator 31 and feed back the signal to the first host 324. Then, the first host 324 feeds back the signal to the electrical control component 1. The electrical control component 1 generates a control command signal based on the feedback signal and sends it to the first host 324. The first host 324 controls the operation of the first metering pump 323 according to the control command. After the specified value of the amount of high-pressure air transmitted to the oxygen generator 31 is reached in the control command input on the control panel 9, the electrical control component 1 will control the corresponding first metering pump 323 to shut down, thereby achieving control over the oxygen production of the oxygen generator 31.

[0028] Specifically, such as Figure 3 and Figure 5 As shown, the first gas supply pipe 322 extends from the second housing 5 into the third housing 6, and the portion located inside the third housing 6 is connected to a first electrically controlled valve 325, which is electrically connected to the first main unit 324.

[0029] In this system, the user controls the first electrically controlled valve 325 by inputting command signals into the control panel 9. After the command signal is transmitted to the electrical control component 1, the electrical control component 1 generates a control command signal to the first host 324 based on the command signal. The first host 324 controls the first electrically controlled valve 325 to close based on the control command signal, thereby blocking the operation of the air handling module 2 to transmit high-pressure air to the oxygen generator 31 through the first air supply pipe 322, and thus controlling the working status of the oxygen generator.

[0030] It needs to be further explained that, such as Figures 3-6As shown, the gas transmission structure 32 further includes a second host 326, a second housing 327, a second gas transmission pipe 328, and a second metering pump 329. The second host 326 is fixedly connected to the wall at the top of the middle part of the third housing 6. The second housing 327 is fixedly connected above the second host 326. The second gas transmission pipe 328 is branched and connected to the output end of the top of the oxygen generator 31 and extends into the second housing 327. The second metering pump 329 is connected to the portion of the second gas transmission pipe 328 that extends from the transmission end of the oxygen generator 31 into the second housing 327. The portion of the second gas transmission pipe 328 located inside the second housing 327 sequentially passes through the wall at the end of the second housing 327 and the top surface of the top cover 7 and is connected to the connector 8. The second host 326 is electrically connected to the electrical control component 1 and the second metering pump 329, respectively.

[0031] The user controls the second metering pump 329 corresponding to the oxygen generator 31 at different locations in the third housing 6 by inputting command signals on the control panel 9. After the command signal is transmitted to the electrical control component 1, the electrical control component 1 generates a corresponding control command based on the command signal and transmits it to the second host 326. The second host 326 controls the second metering pump 329 at the designated location to pump the oxygen from the oxygen generator 31 into the second gas delivery pipe 328 inside the second housing 327. The oxygen is then delivered to the connector 8 for output using the second gas delivery pipe 328 inside the second housing 327, thus realizing the output of the generated oxygen from the oxygen generator to the outside of the machine. The operation is as follows: the second metering pump 329 can calculate the amount of high-pressure air input into the oxygen tank 31 and feed back the signal to the second host 326. Then, the second host 326 feeds back the signal to the electrical control component 1. The electrical control component 1 generates a control command signal based on the feedback signal and sends it to the second host 326. The second host 326 controls the operation of the second metering pump 329 according to the control command. After the specified value for the output of oxygen tank 31 to the second gas pipeline 328 is reached in the control command input to the control panel 9, the electrical control component 1 will control the corresponding second metering pump 329 to shut down, thereby achieving control over the amount of oxygen output from the oxygen generator.

[0032] Specifically, such as Figure 3 and Figure 6 As shown, the portion of the second gas pipeline 328 located between the second housing 327 and the top cover 7 is connected to a second electrically controlled valve 3210, which is electrically connected to the second main unit 326.

[0033] In this system, the user controls the second electrically controlled valve 3210 by inputting command signals into the control panel 9. After the command signal is transmitted to the electrical control component 1, the electrical control component 1 generates a control command signal to the second host 326 based on the command signal. The second host 326 controls the second electrically controlled valve 3210 to close based on the control command signal, thereby blocking the operation of the air handling module 2 to output oxygen to the control connector 8 through the second air supply pipe 328, and thus controlling the output oxygen amount of the oxygen generator.

[0034] It needs to be further explained that, such as Figure 2 and Figure 7 As shown, one side wall of the third housing 6 is provided with a first through hole 62, and the wall of the third housing 6 located outside the first through hole 62 is provided with a first mating groove 63. A first fixing plate 64 is fitted in the first mating groove 63. A second through hole 641 is provided in the middle of the first fixing plate 64. A first exhaust fan 10 with an air outlet facing the second through hole 641 is fixedly connected to the inner wall of the first fixing plate 64.

[0035] The first exhaust fan 10 can extract hot air from the third housing 6, preventing the temperature inside the third housing 6 from becoming too high and affecting the normal operation of the oxygen generating component 3. The first through hole 62 allows the first exhaust fan 10 to be easily installed into the third housing 6 through the first through hole 62, or to be easily removed from the third housing 6 through the first through hole 62 when it is being removed from the third housing 6.

[0036] It needs to be further explained that, such as Figure 1 and Figure 2 As shown, a third through hole 51 is provided on one side wall of the second housing 5, and a second mating groove 52 is provided on the wall outside the third through hole 51. A second fixing plate 53 is fitted in the second mating groove 52, and a fourth through hole 531 is provided in the middle of the second fixing plate 53. A second exhaust fan 11 with an air outlet facing the fourth through hole 531 is fixedly connected to the inner wall of the second fixing plate 53.

[0037] The second exhaust fan 11 can extract hot air from the second housing 5, preventing the temperature inside the second housing 5 from becoming too high and affecting the normal operation of the air handling module 2. The third through hole 51 allows the second exhaust fan 11 to be easily installed into the third housing 6 through the third through hole 51 when it is installed into the second housing 5, or to be easily removed from the third housing 6 through the third through hole 51 when it is removed from the second housing 5.

[0038] It needs to be further explained that, such as Figure 1and Figure 7 As shown in the figure, a door 12 is provided on one side wall of the first housing 4 and the third housing 6.

[0039] When maintenance personnel are performing maintenance on the electrical control component 1 and the oxygen generating component 3, they can open the machine door 12 to expose the electrical control component 1 in the first housing 4 and the oxygen generating component 3 in the third housing 6 to the outside, thus facilitating maintenance personnel to perform maintenance on the electrical control component 1 and the oxygen generating component 3.

[0040] It needs to be further explained that, such as Figure 1 As shown, four corners of the bottom of the first housing 4 are fixedly connected with casters 13.

[0041] The oxygen concentrator can be moved using the 13-wheel mechanism, and its position can be fixed after it has been moved to a designated location, making the adjustment of the oxygen concentrator's position more convenient.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
