Abstract
Description
Technical Field
[0001] This application relates to the field of oxygen generation equipment technology, and in particular to an adsorption device and method for a horizontal vehicle-mounted oxygen generator with short-circuit protection. Background Technology
[0002] With increasing emphasis on health and the continuous development of in-vehicle devices, in-vehicle oxygen generators have been widely used in car travel, providing convenient oxygen supply for passengers. The adsorption device is one of the core components of an in-vehicle oxygen generator; its main function is to adsorb gases such as nitrogen from the air using an adsorbent, thereby producing a high concentration of oxygen.
[0003] Currently, most mainstream vehicle-mounted oxygen generators use a vertical adsorption structure. However, vertical adsorption devices do not make efficient use of space in a vehicle environment, often occupying a significant amount of vertical space. In the relatively compact interior environment of a vehicle, this can easily lead to layout conflicts with other components, hindering the optimization of the overall structure.
[0004] Meanwhile, existing adsorption devices, including some that attempt horizontal designs but haven't adequately addressed short-circuit prevention, are prone to molecular sieve pulverization during prolonged use, leading to gas short-circuiting. This short-circuiting causes some insufficiently adsorbed air to directly enter subsequent gas production stages, reducing the concentration of produced oxygen and affecting the oxygen generator's efficiency. Furthermore, short-circuiting can also reduce adsorbent utilization, increasing energy consumption and operating costs.
[0005] Furthermore, the vehicle environment has certain unique characteristics. Bumps and vibrations during vehicle operation can affect the stability of the adsorption device, further increasing the risk of gas short circuits. Existing adsorption devices do not adequately consider short-circuit protection and adaptation to vehicle vibration environments in their structural design, making it difficult to meet practical application requirements. Summary of the Invention
[0006] The purpose of this application is to provide a short-circuit-proof horizontal vehicle-mounted oxygen generator adsorption device and method, which can effectively prevent gas short-circuit phenomena.
[0007] To achieve the above objectives, this application provides a short-circuit-proof horizontal vehicle-mounted oxygen generator adsorption device, comprising: an adsorption column and a short-circuit-proof component;
[0008] The adsorption column has a hollow structure;
[0009] The short-circuit protection component includes a first elastic element and a partition. The partition is disposed inside the adsorption column and is connected to the inner wall of the adsorption column through the first elastic element. The partition divides the interior of the adsorption column into an adsorption cavity and an empty cavity, and the adsorption cavity is filled with an adsorbent.
[0010] In some embodiments, the adsorption column is placed horizontally, and both ends of the adsorption column are provided with end caps, one of the end caps being an air inlet and the other end cap being an air outlet.
[0011] In some embodiments, the short-circuit protection assembly further includes a sealing strip, which is fixedly connected to the side wall of the partition and is in close contact with the side wall of the adsorption column.
[0012] In some embodiments, the sealing strip is flexible, and a second elastic element is provided between the sealing strip and the partition, the second elastic element being used to push the sealing strip to always be in close contact with the inner wall of the adsorption column.
[0013] In some embodiments, there are multiple second elastic elements, which are evenly spaced between the sealing strip and the partition.
[0014] In some embodiments, there are multiple first elastic elements, which are evenly distributed at intervals between the inner wall of the adsorption column and the partition.
[0015] In some embodiments, a horizontal fixing plate is provided on the inner wall of the adsorption column, and the inner wall of the adsorption column is connected to the first elastic member through the horizontal fixing plate.
[0016] In some embodiments, the air inlet of the adsorption column is provided with an airflow distribution plate, and the airflow distribution plate is provided with a plurality of spaced ventilation holes.
[0017] In some embodiments, the adsorption column is made of a pressure-resistant and shock-resistant material.
[0018] An adsorption method for a short-circuit-resistant horizontal vehicle-mounted oxygen concentrator, applied to the aforementioned short-circuit-resistant horizontal vehicle-mounted oxygen concentrator, includes the following steps:
[0019] The airflow is evenly distributed. The gas is introduced into the adsorption column through the air inlet. The gas passes through the airflow distribution plate and enters the adsorption chamber. The airflow distribution plate makes the air evenly dispersed in the adsorption chamber.
[0020] Full adsorption occurs when the gas comes into contact with the adsorbent in the adsorption chamber, thus completing the adsorption process to produce oxygen.
[0021] The gas is discharged, driving the adsorbed gas to exit the adsorption column from the outlet.
[0022] Compared to the aforementioned background technology, the short-circuit-preventing horizontal vehicle-mounted oxygen concentrator adsorption device provided in this application includes an adsorption column and a short-circuit-preventing component. The adsorption column is a hollow structure, and the short-circuit-preventing component includes a first elastic element and a partition. The partition is disposed inside the adsorption column and is connected to the inner wall of the adsorption column through the first elastic element. The partition divides the interior of the adsorption column into an adsorption chamber and an empty chamber, with the adsorption chamber filled with adsorbent. The first elastic element is always in a compressed state, applying a pushing force to the partition, thereby causing the partition to compress the adsorbent in the adsorption chamber. This compression makes the adsorbent in the adsorption chamber dense, preventing relative movement between adsorbent particles even during vehicle vibration, thus preventing adsorbent friction and pulverization, ensuring sufficient contact between the gas and the adsorbent, and preventing gas short circuits. The short-circuit-preventing horizontal vehicle-mounted oxygen concentrator adsorption device and method of this application can adapt to confined vehicle spaces and prevent adsorbent pulverization during vibration, thereby preventing gas short circuits, ensuring adsorbent utilization efficiency, reducing energy consumption, and lowering operating costs.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.
[0035] Example 1:
[0036] like Figures 1 to 3 As shown, the anti-short-circuit horizontal vehicle-mounted oxygen generator adsorption device provided in this application embodiment includes an adsorption column 1 and an anti-short-circuit component 2. The adsorption column 1 is a hollow structure. The anti-short-circuit component 2 includes a first elastic element 21 and a partition 22. The partition 22 is disposed inside the adsorption column 1. The partition 22 is connected to the inner wall of the adsorption column 1 through the first elastic element 21. The partition 22 divides the inside of the adsorption column 1 into an adsorption chamber and an empty cavity. The adsorption chamber is filled with an adsorbent 3.
[0037] Specifically, the adsorption column 1 has a cylindrical inner cavity structure. The partition 22 is connected to the top surface of the adsorption column 1 through the first elastic element 21, which can be a spring. The partition 22 divides the cylindrical inner cavity structure into an adsorption cavity and an empty cavity. The volume of the adsorption cavity is larger than the volume of the empty cavity. The adsorption cavity is located below the partition 22, and the empty cavity is located above the partition 22. The first elastic element 21 is located in the empty cavity. The adsorption cavity is filled with an adsorbent 3, which can be a molecular sieve for oxygen production. The molecular sieve for oxygen production has a spherical structure.
[0038] It is understandable that the first elastic element 21 is always in a compressed state. The first elastic element 21 applies a pushing force to the partition 22, thereby causing the partition 22 to compress the adsorbent 3 in the adsorption chamber, thus making the adsorbent 3 in the adsorption chamber dense. Even if the vehicle vibrates during driving, it can prevent relative movement between the adsorbents 3, thereby preventing the adsorbents 3 from rubbing and pulverizing, so that the gas can fully contact the adsorbent 3 and prevent gas circuit break.
[0039] In some embodiments, the adsorption column 1 is placed horizontally, with end caps 4 at both ends, one end cap 4 having an air inlet 5 and the other end cap 4 having an air outlet 6.
[0040] Specifically, the two end caps 4 are detachably installed at both ends of the adsorption column 1 by bolts. The outer contour of the end cap 4 is the same as the cross section of the adsorption column 1. The end cap 4 can be fitted onto the adsorption column 1. The two end caps 4 are symmetrically distributed at both ends of the adsorption column 1. One end cap 4 has an air inlet 5 at its center and the other end cap 4 has an air outlet 6 at its center. The air inlet 5 and the air outlet 6 are symmetrically distributed.
[0041] It is understood that by placing the adsorption column 1 horizontally, the vertical space occupied by the adsorption column 1 can be reduced, thereby allowing the adsorption column 1 to be placed in vehicles with low heights, improving the versatility of the adsorption column 1. At the same time, placing the adsorption column 1 horizontally can also avoid layout conflicts with other components, which is beneficial to the overall structural optimization. It is understood that in some other embodiments, the shape of the adsorption column 1 can be cylindrical, cuboid, polygonal, or other shapes adapted to the interior space of the vehicle.
[0042] In some embodiments, the anti-short circuit component 2 further includes a sealing strip 23, which is fixedly connected to the side wall of the partition 22 and is in close contact with the side wall of the adsorption column 1.
[0043] Specifically, the sealing strip 23 can be a ring structure. The sealing strip 23 is installed on the periphery of the partition 22. The partition 22 is tightly attached to the side wall of the adsorption column 1 through the sealing strip 23, thereby achieving a sealing fit between the partition 22 and the inner wall of the adsorption column 1.
[0044] It is understandable that setting a sealing strip 23 around the partition 22 can maintain the airtightness of the adsorption chamber and prevent the adsorbent 3 or the gas to be adsorbed from entering the cavity.
[0045] Preferably, the sealing strip 23 is flexible, and a second elastic element 24 is provided between the sealing strip 23 and the partition 22. The second elastic element 24 is used to push the sealing strip 23 to always be in close contact with the inner wall of the adsorption column 1.
[0046] Specifically, the sealing strip 23 can be a high-temperature resistant and aging-resistant rubber ring. The sealing strip 23 is flexible and can deform under force. The side wall of the partition 22 has a first mating groove, which surrounds the periphery of the partition 22. The sealing strip 23 has an annular structure and can be embedded in the first mating groove. The sealing strip 23 has a second mating groove near the side wall of the partition 22. The second elastic element 24 is located in the second mating groove. The second elastic element 24 can be a spring. One end of the second elastic element 24 is fixedly connected to the partition 22, and the other end is fixedly connected to the sealing strip 23.
[0047] Understandably, the second elastic element 24 is always in a compressed state. The second elastic element 24 can provide thrust to the sealing strip 23, thereby pushing the sealing strip 23 to always be in close contact with the inner wall of the adsorption column 1. The contact position between the sealing strip 23 and the adsorption column 1 is deformed due to compression, thereby making the sealing strip 23 tightly fit with the inner wall of the adsorption column 1. Even if the partition 22 moves up and down due to vibration, the sealing strip 23 can still be in close contact with the inner wall of the adsorption column 1 under the thrust of the second elastic element 24, thus ensuring that the adsorption chamber can still be sealed under vibration.
[0048] Based on the above embodiments, there are multiple second elastic elements 24, which are evenly distributed between the sealing strip 23 and the partition plate 22.
[0049] It is understandable that by setting multiple second elastic elements 24, the pressure on a single second elastic element 24 can be reduced, and the sealing strip 23 can be subjected to force evenly, thus avoiding premature aging of the sealing strip 23 due to uneven force.
[0050] In some embodiments, there are multiple first elastic elements 21, which are evenly distributed between the inner wall of the adsorption column 1 and the partition 22, and the interval between adjacent first elastic elements 21 is 5 cm.
[0051] It is understandable that by setting multiple first elastic elements 21, the pressure on a single first elastic element 21 can be reduced, thereby increasing the service life of the first elastic element 21.
[0052] Based on the above embodiments, a horizontal fixing plate 7 is provided on the inner wall of the adsorption column 1, and the inner wall of the adsorption column 1 is connected to the first elastic member 21 through the horizontal fixing plate 7.
[0053] Specifically, the horizontal fixing plate 7 is fixedly installed at the top of the cavity of the adsorption column 1. The bottom surface of the horizontal fixing plate 7 is horizontally distributed and parallel to the partition plate 22. One end of the first elastic member 21 is connected to the horizontal fixing plate 7, and the other end is connected to the partition plate 22.
[0054] It is understandable that the distance between any position of the horizontal fixed plate 7 and the partition plate 22 is equal, so that the multiple first elastic elements 21 are subjected to uniform force. Therefore, springs of the same model can be used as the first elastic elements 21 to save costs.
[0055] In some embodiments, an airflow distribution plate 8 is provided at the inlet of the adsorption column 1, and the airflow distribution plate 8 is provided with a plurality of spaced ventilation holes.
[0056] Specifically, the airflow distribution plate 8 has the same shape as the inner cavity of the adsorption column 1. The airflow distribution plate 8 is fixedly installed in the inner cavity of the adsorption column 1. The top of the airflow distribution plate 8 has a baffle 81, the shape of which is the same as the cross-section of the cavity. The baffle 81 can seal the cavity, and when the partition plate 22 moves up and down, its sidewall is always in close contact with the baffle 81. Other areas of the airflow distribution plate 8 are provided with multiple vent holes of the same size, which are evenly distributed on the airflow distribution plate 8.
[0057] It is understandable that when the gas enters the adsorption column 1 from the inlet 5, the baffle 81 can prevent the gas from entering the cavity, and the airflow distribution plate 8 can evenly disperse the gas so that the gas is evenly dispersed into the adsorption cavity, thereby increasing the contact area between the gas and the adsorbent 3 in the adsorption cavity and thus improving the adsorption efficiency.
[0058] In some embodiments, the adsorption column 1 is made of a pressure-resistant and shock-resistant material.
[0059] Understandably, pressure-resistant and shock-resistant materials can be die-cast aluminum alloys.
[0060] Example 2:
[0061] like Figures 4 to 6 As shown, the short-circuit-proof horizontal vehicle-mounted oxygen generator adsorption device provided in this application includes an adsorption column 1 and a short-circuit-proof component 2. The adsorption column 1 is a rectangular hollow structure. The short-circuit-proof component 2 includes a first elastic element 21 and a partition 22. Multiple first elastic elements 21 are evenly distributed between the partition 22 and the top surface of the adsorption column 1. The first elastic element 21 can be a spring, one end of which is fixedly connected to the top surface of the adsorption column 1, and the other end of which is fixedly connected to the partition 22. The partition 22 divides the inner cavity of the adsorption column 1 into a cavity and an adsorption cavity. The cavity is located above the partition 22, and the adsorption cavity is located below the partition 22. The adsorption cavity is filled with an adsorbent 3, which can be a molecular sieve for oxygen generation.
[0062] Compared with Embodiment 1, in this embodiment, since the adsorption column 1 itself is a cuboid structure with its top surface horizontally arranged, the first elastic element 21 can be directly connected to the top surface of the adsorption column 1. At the same time, since the two side walls of the adsorption column 1 are distributed in parallel and spaced apart, the side wall of the partition plate 22 can always be in close contact with the side wall of the adsorption column 1, and there is no need to set the sealing strip 23 and the second elastic element 24 as in Embodiment 1.
[0063] The adsorption method for the anti-short-circuit horizontal vehicle-mounted oxygen generator provided in this application includes the following steps:
[0064] With uniform airflow, after the vehicle-mounted oxygen generator is started, the gas enters the adsorption column 1 from the air inlet 5, passes through the airflow distribution plate 8 and enters the adsorption chamber. The airflow distribution plate 8 makes the air evenly dispersed in the adsorption chamber.
[0065] Fully adsorbed, the uniformly dispersed gas comes into full contact with adsorbent 3 to complete the adsorption and oxygen production;
[0066] The gas is discharged, and the adsorbed oxygen-rich gas is discharged from the outlet 6 of the adsorption column 1.
[0067] In summary, the short-circuit-preventing horizontal vehicle-mounted oxygen generator adsorption device and method of this application can adapt to the confined space of a vehicle and can prevent the adsorbent 3 from pulverizing during vibration, thereby avoiding gas short circuits, ensuring the utilization efficiency of the adsorbent 3, reducing energy consumption, and lowering operating costs. It should be noted that in this specification, relational terms such as "first" and "second" are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0068] The above provides a detailed description of the anti-short-circuit horizontal vehicle-mounted oxygen generator adsorption device and method provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
