The height of the bottom surface of each tank body arranged in sequence along the airflow direction is lowered in sequence, so that the liquid in the front tank body flows to the rear tank body through the pipe, and is discharged centrally through a unified drain port, which not only effectively reduces the consumption of high-pressure air during exhaust, improves the production efficiency of high-pressure air, reduces the operating cost, but also simplifies the control system, facilitates control operation, reduces the equipment cost, and improves the use experience.

[0005] As preferred, the inlet of the pipe is higher than the outlet, so that the liquid in the front tank can flow through the pipe and be delivered to the rear tank by gravity. The pipe receives the liquid and high-pressure air from the front tank through the inlet, and delivers them to the rear tank through the outlet, which is convenient for the delivery and storage of high-pressure air, and for the collection and delivery of liquid to the rear tank.

[0006] As preferred, the tank is provided with a cylindrical tank cavity, and the bottom of the tank cavity is provided with a conical cavity with a large top and a small bottom. The inlet of the pipe is connected to the bottom end of the conical cavity, and the liquid in the tank cavity flows downward and converges to the inlet through the conical cavity.

The conical cavity can guide the liquid on the side wall to converge to the inlet and be delivered to the rear.

[0007] As preferred, the outlet of the pipe is arranged on the side wall of the corresponding conical cavity of the tank, so that the liquid from the outlet converges downward along the side wall of the conical cavity and is discharged. In the same tank, the side wall of the conical cavity is provided with the outlet of the front pipe, and the bottom of the conical cavity is provided with the inlet of the rear pipe. The outlet of the front pipe is higher than the inlet of the rear pipe, which ensures that the liquid can flow in the predetermined direction under the action of gravity, and prevents the liquid from flowing in the opposite direction.

[0008] As preferred, the bottom surfaces of adjacent tanks have a height difference H1, H1≥5cm, which ensures that the inlet and outlet of the pipe have a height difference, guarantees that the liquid can flow in the predetermined direction in the pipe, and reserves a height between the outlet and the bottom surface of the corresponding tank, which prevents the liquid from flowing in the opposite direction.

[0009] As preferred, the tank has at least two, including a primary tank and a final tank.

By increasing the height difference between the bottom surface of the final tank and the bottom surface of the second last tank, the water collection space is increased, which is convenient for storing more liquid, prevents the liquid from flowing in the opposite direction due to flooding of the corresponding pipe, and effectively reduces the drainage frequency, thereby reducing the consumption of high-pressure air required for air discharge.

[0011] As preferred, the tank body comprises a middle-stage tank arranged between the primary tank and the final-stage tank, the bottom surface of the primary tank is higher than the bottom surface of the middle-stage tank, there is a height difference between the bottom surfaces of adjacent middle-stage tanks, and the bottom surface of the middle-stage tank is higher than the bottom surface of the final-stage tank. The middle-stage tank is arranged between the primary tank and the final-stage tank, and the bottom surfaces of the middle-stage tanks are sequentially lowered in stages, thereby guiding the liquid to converge to the final-stage tank.

[0012] An oxygen generator comprises a raw gas assembly, an adsorption tower assembly and a finished gas storage assembly. The raw gas assembly comprises an air compressor, a condenser and an air tank group. The raw gas assembly is used for producing and storing high-pressure air. The adsorption tower assembly separates the high-pressure air and delivers finished gas to the finished gas storage assembly, thereby completing gas preparation.

[0013] As preferred, the air tank group is one group, and the air compressor, the condenser and the air tank group are sequentially arranged in series from front to back. The air tank group is used for storing and draining the high-pressure air cooled by the condenser, thereby ensuring that the humidity of the high-pressure air meets the subsequent processing requirements.

[0014] As preferred, the air tank group is two groups, and the condenser is arranged between the air tank groups. The number of the air tank groups is increased to improve the drainage efficiency of the high-pressure air, thereby ensuring that the humidity of the high-pressure air meets the subsequent use requirements.

[0015] The utility model discloses a beneficial effect: the height of each tank body bottom surface arranged in sequence along the direction of air flow is lowered in sequence, so that the liquid in the front tank body is self-flowed to the rear tank body through the pipe fitting, and is concentrated and discharged through the unified drainage port, which not only effectively reduces the high-pressure air consumption during exhaust, improves the high-pressure air production efficiency and reduces the operation cost, but also simplifies the control system, facilitates control operation, reduces the equipment cost and improves the use experience.

[0020] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1:

[0022] This embodiment provides a heterogeneous honeycomb air compressor tank assembly.

[0023] like Figure 1 The illustrated compressed air tank assembly includes several tanks. The tanks, connected in series from front to back along the airflow direction, have progressively lower bottom heights. The bottom surface of the front tank is connected to the bottom sidewall of the rear tank via a pipe fitting 1, allowing liquid within the tanks to flow along the pipe fitting 1 under the influence of airflow and be centrally discharged. This progressively lower bottom height of the tanks along the airflow direction allows liquid in the front tank to flow by gravity through the pipe fitting 1 to the rear tank, and then be centrally discharged through a unified drain outlet 11. This effectively reduces high-pressure air consumption during exhaust, improves high-pressure air production efficiency, lowers operating costs, simplifies the control system, facilitates operation, reduces equipment costs, and enhances the user experience.

[0024] In this embodiment, there are at least two tanks, including a primary tank 6 and a final tank 7. An intermediate tank 8 can be added between the primary tank 6 and the final tank 7 to increase the capacity of the compressed air tank assembly. The tank assembly includes an intermediate tank 8 positioned between the primary tank 6 and the final tank 7. The bottom surface of the primary tank 6 is higher than the bottom surface of the intermediate tank 8, and there is a height difference between the bottom surfaces of adjacent intermediate tanks 8. The bottom surface of the intermediate tank 8 is higher than the bottom surface of the final tank 7. Preferably, there are five tanks, including a primary tank 6, a final tank 7, and three intermediate tanks 8. The bottom surfaces of each tank are progressively lowered according to a preset arrangement to ensure that the liquid in each tank flows towards the final tank 7 by gravity.

[0025] In this embodiment, adjacent tanks are connected by a pipe fitting 1, and the inlet 2 of the pipe fitting 1 is higher than the outlet 3 (e.g., Figure 2 As shown in the diagram, the liquid in the pre-stage tank is transported to the post-stage tank by gravity through pipe 1. Specifically, the bottom center of the primary tank 6 is connected to the inlet 2 of the corresponding pipe 1, and the bottom sidewall of the adjacent intermediate tank 8 is connected to the outlet 3 of the same pipe 1. This ensures that the liquid collected in the primary tank 6 can flow through pipe 1 to the adjacent intermediate tank 8. The adjacent intermediate tanks 8 and the intermediate tank 8 are all connected to the adjacent final tank 7 through corresponding pipe 1, guiding the liquid in each tank to the water collection space of the final tank 7. The liquid in each tank is transported to the water collection space. High-pressure air is present in the final tank 7. When the drain port 11 is opened, the liquid will be discharged through the drain port 11 under the compression of the high-pressure air. By reducing the number of drainages, the loss of high-pressure air is reduced, thereby effectively improving the high-pressure air production efficiency and reducing energy consumption.

[0026] In the embodiment, the tank body is provided with a cylindrical tank cavity 4, the bottom of the tank cavity 4 is provided with a conical cavity 5 with a large top and a small bottom, the inlet 2 of the pipe 1 is connected to the bottom end of the conical cavity 5, and the liquid in the tank cavity 4 flows downward and is collected and delivered to the inlet 2 through the conical cavity 5. The top surface diameter of the conical cavity 5 matches the diameter of the tank cavity 4, ensuring that the side wall edges of the two are smoothly connected, facilitating the downward flow and collection of the liquid.

[0027] In the embodiment, the outlet 3 of the pipe 1 is arranged on the side wall of the conical cavity 5 corresponding to the tank body, so that the liquid from the outlet 3 converges downward along the side wall of the conical cavity 5 and is discharged. The outlet 3 of the pipe 1 is horizontally arranged, and the liquid and air flow ejected from the outlet 3 will collide with the side wall of the conical cavity 5 and move upward, the liquid will fall back to the bottom of the tank due to its own gravity, and the high-pressure air will remain in the tank, playing a role in storing high-pressure air.

[0028] As a preferred, the bottom surfaces of adjacent tank bodies have a height difference H1, H1≥5cm, and preferably H1=8cm, to ensure that the corresponding pipes 1 of the adjacent tank bodies have installation space and ensure that the liquid can flow freely along the predetermined path. The bottom of the last-stage tank 7 forms a water collection space, and the bottom surfaces of the last-stage tank 7 and the adjacent tank bodies have a height difference H2, 20cm≤H2≤30cm, and preferably H2=25cm, to provide a larger water collection space for the liquid, thereby reducing the opening frequency of the drain port 11, which can not only discharge more water through a single opening of the drain port 11, but also reduce the loss of high-pressure air by reducing the number of drainage.

[0029] As a preferred, the top of the primary tank 6 is provided with an air inlet 9 (as shown in Figure 3 The top of the last-stage tank 7 is provided with an air outlet 10, and the bottom end of the last-stage tank 7 is provided with a drain port 11 connected to the outside. The air inlet 9 is used to receive high-pressure air, the air outlet 10 is used to discharge high-pressure air, and the drain port 11 is one and is arranged at the bottom of the last-stage tank 7, and is used to discharge the liquid in the water collection space.

[0030] Embodiment two:

[0031] The embodiment provides an oxygen generator.

[0032] An oxygen generator, which is composed of a raw gas assembly, an adsorption tower assembly and a finished gas storage assembly. The raw gas assembly includes an air compressor, a condenser and the air tank group. The raw gas assembly is used to produce and store high-pressure air, the adsorption tower assembly separates the high-pressure air and delivers the finished gas to the finished gas storage assembly, thereby completing the gas preparation.

[0033] In the embodiment, the air compression tank group is one or two groups, which can be adjusted according to the use requirement, and should be regarded as the specific embodiment of the embodiment. When the air compression tank group is one group, the air compressor, the condenser and the air compression tank group are sequentially connected from front to back. When the air compression tank group is two groups, the condenser is arranged between the air compression tank groups, so as to form the arrangement mode of air compressor, air compression tank group, condenser and air compression tank group.

[0034] In the embodiment, the air compression tank group can also be used in the preparation device of other similar gas, such as nitrogen making machine, which should also be regarded as the specific embodiment of the embodiment.

[0035] The other structure and effect of the air compression tank group in the embodiment are the same as those in the first embodiment, and will not be described again.
