Description

Technical Field

[0001] This utility model relates to the field of gas storage tanks, specifically a gas storage tank with a drainage structure. Background Technology

[0002] An air tank is a pressure vessel used to store compressed air or other gases. Its core functions include stabilizing the supply pressure, buffering system fluctuations, separating impurities, and saving energy and reducing consumption. It is widely used in industries, energy, medical fields, and other fields.

[0003] In the prior art, such as in publication number CN216743818U, a gas storage tank is disclosed, which includes: a shell having a gas storage cavity inside; a first sub-tank, a second sub-tank, and a third sub-tank disposed in the gas storage cavity; a connecting pipe, which includes a first sub-pipe connecting the first sub-tank and the second sub-tank, and a second sub-pipe connecting the second sub-tank and the third sub-tank; a first electrically controlled valve disposed on the first sub-pipe; and a second electrically controlled valve disposed on the second sub-pipe.

[0004] Although the aforementioned patent has a simple structure and can store multiple gases simultaneously as needed, water vapor remains inside the gas storage tank when it is filled with gas. As the water vapor accumulates, it affects the use of the gas inside the tank and also increases the weight of the tank itself. Furthermore, it cannot release the water vapor on a timed basis, and when releasing the water vapor, the gas inside the tank must be released as well, resulting in gas waste. Therefore, a gas storage tank with a drainage structure is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, when gas is filled into a gas storage tank, water vapor remains inside. As the water vapor accumulates, it affects the use of the gas inside the tank and increases the weight of the tank itself. Furthermore, it is impossible to release the water vapor on a timed basis, and when releasing the water vapor, the gas inside the tank must be released at the same time, resulting in gas waste. This utility model proposes a gas storage tank with a drainage structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The gas storage tank with a drainage structure of this utility model includes a tank body; a conical disc is fixedly connected to the bottom of the tank body, a water leakage groove is opened at the bottom of the conical disc, a check valve is installed inside the water leakage groove, and a conical cover is connected through the bottom of the check valve; a water storage pan is provided at the bottom of the tank body, a sliding groove is opened on the inner side wall of the water storage pan, a sliding plate is slidably connected inside the sliding groove, a fixing ring is fixedly connected to the back of the sliding plate, an airbag buoyancy ball is sleeved inside the fixing ring, a sealing disc is fixedly connected to the bottom of the sliding plate, an elastic sealing ring is provided on the surface of the sealing disc, a drain hole is opened on the side of the water storage pan, and a drain pipe is connected through the surface of the drain hole.

[0007] Preferably, an air outlet pipe is provided at the top of the tank, and an air inlet pipe is provided at the bottom of the tank, with the axes of the air outlet pipe and the air inlet pipe perpendicular to the central axis of the tank.

[0008] Preferably, the cross-section of the elastic sealing ring is V-shaped, and the V-shaped opening faces the drain hole and is vulcanized and bonded to the sealing disc.

[0009] Preferably, the conical cover is made of polytetrafluoroethylene and the inner wall surface is polished, and the taper angle of the conical cover is greater than the taper angle of the conical disk.

[0010] Preferably, the inner wall of the slide groove is coated with a wear-resistant lubricating coating, and a self-lubricating nylon slider is embedded in the contact surface between the slide plate and the slide groove.

[0011] Preferably, the airbag buoyancy ball is made of butyl rubber and filled with inert gas, and the fixing ring is fastened to the airbag buoyancy ball by a clamp.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves efficient separation of water vapor and one-way drainage in the gas storage tank through the coordinated design of the conical disc and the check valve. The condensate flows into the water storage pan through the drain trough, and the check valve blocks the backflow of gas, which solves the problem of gas discharge required for drainage in traditional gas storage tanks, avoids gas waste and maintains stable pressure inside the tank.

[0014] 2. This utility model uses a linkage structure design between an airbag buoyancy ball and a sliding plate. When the water level in the water storage pan rises, the buoyancy ball drives the sliding plate to move upward along the slide groove, and the sealing plate disengages from the drain hole to automatically drain water. This solves the problems of cumbersome manual operation and delayed drainage, and realizes unattended intelligent drainage control. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1-4 As shown, a gas storage tank with a drainage structure includes a tank body 1; a conical disc 2 is fixedly connected to the bottom of the tank body 1, a water leakage groove 3 is opened at the bottom of the conical disc 2, a check valve 4 is installed inside the water leakage groove 3, and a conical cover 5 is connected through the bottom of the check valve 4; a water storage pan 6 is provided at the bottom of the tank body 1, a sliding groove 7 is opened on the inner side wall of the water storage pan 6, a sliding plate 8 is slidably connected inside the sliding groove 7, a fixing ring 9 is fixedly connected to the back of the sliding plate 8, an airbag buoyancy ball 10 is sleeved inside the fixing ring 9, a sealing disc 11 is fixedly connected to the bottom of the sliding plate 8, an elastic sealing ring 12 is provided on the surface of the sealing disc 11, a drain hole 13 is opened on the side of the water storage pan 6, and a drain pipe 14 is connected through the surface of the drain hole 13.

[0023] During operation, condensate flows along the inner wall of tank 1 to conical disc 2, then through drain groove 3, through check valve 4, and into water storage pan 6. When the water level rises, the buoyancy ball 10 of the airbag is pushed by buoyancy to slide plate 8 along slide groove 7, and sealing disc 11 disengages from drain hole 13 to open drainage. After the water level drops, the buoyancy ball 10 drives sealing disc 11 to reset and close drain hole 13. Elastic sealing ring 12 is compressed and sealed, realizing automatic drainage of the gas storage tank and zero gas leakage, solving the energy waste problem caused by the need for depressurization in traditional drainage.

[0024] Furthermore, an exhaust pipe 15 is provided at the top of the tank body 1, and an intake pipe 16 is provided at the bottom of the tank body 1. The axes of the exhaust pipe 15 and the intake pipe 16 are perpendicular to the central axis of the tank body 1.

[0025] During operation, the exhaust pipe 15 is vertically installed at the top of the tank 1, and the intake pipe 16 is vertically installed at the bottom. After the gas is filled through the intake pipe 16, it is evenly distributed by the conical disk 2. When draining, the gas is stably output through the exhaust pipe 15. The vertical pipe layout reduces airflow disturbance, improves gas storage and output efficiency, and facilitates equipment integration and installation.

[0026] Furthermore, the cross-section of the elastic sealing ring 12 is V-shaped, with the V-shaped opening facing the drain hole 13 and being vulcanized and bonded to the sealing disc 11.

[0027] During operation, the V-shaped elastic sealing ring 12 expands outward under water pressure when the sealing disc 11 is closed. The V-shaped opening tightly adheres to the inner wall of the drain hole 13 to form multiple seals. The vulcanization bonding ensures that the elastic sealing ring 12 and the sealing disc 11 are in long-term contact. The V-shaped structure dynamically adapts to changes in water pressure, extending the sealing life and reducing the frequency of maintenance.

[0028] Furthermore, the conical cover 5 is made of polytetrafluoroethylene and its inner wall surface is polished. The taper angle of the conical cover 5 is greater than that of the conical disk 2.

[0029] During operation, the inner wall of the PTFE conical cover 5 is mirror-polished, and the condensate slides quickly into the water storage pan 6 along the inclined surface of the conical cover 5. Its taper angle is greater than that of the conical pan 2 to accelerate the water flow away. The smooth surface and taper difference design prevent scale deposition and reduce the risk of drainage channel blockage.

[0030] Furthermore, the inner wall of the slide groove 7 is coated with a wear-resistant lubricating coating, and a self-lubricating nylon slider is embedded in the contact surface between the slide plate 8 and the slide groove 7.

[0031] During operation, the inner wall of the slide groove 7 is coated with a molybdenum disulfide wear-resistant coating, and the self-lubricating nylon slider is embedded in the contact surface of the slide plate 8. The coefficient of friction between the slider and the coating is less than 0.1, which enables the slide plate 8 to lift with low resistance. The wear-resistant coating and the self-lubricating slider work together to extend the service life of the slide groove 7 and make the adjustment smooth and without jamming.

[0032] Furthermore, the airbag buoyancy ball 10 is made of butyl rubber and filled with inert gas, and the fixing ring 9 is fastened to the airbag buoyancy ball 10 by a clamp.

[0033] During operation, the butyl rubber airbag buoyancy ball 10 is filled with nitrogen gas. The clamp locks the airbag buoyancy ball 10 into the fixing ring 9. The tightness of the clamp thread is adjusted to adapt to the volume change of the airbag buoyancy ball 10. The inert gas filling avoids buoyancy attenuation. The clamp fixation prevents the airbag buoyancy ball 10 from falling off.

[0034] Working principle: The condensate of compressed gas in tank 1 flows into water storage pan 6 through water leakage groove 3 along the surface of conical disc 2. Check valve 4 blocks gas backflow. When the water level rises, the airbag buoyancy ball 10 is driven by buoyancy to move the slide plate 8 up along the slide groove 7. The sealing disc 11 disengages from the drain hole 13 to drain water. After the water level drops, the slide plate 8 resets and closes the drain hole 13. The V-shaped elastic sealing ring 12 is pressed tightly against the hole wall to seal. The coating of slide groove 7 and nylon slider reduce friction. The surface of conical cover 5 is smooth to guide flow and prevent blockage. The airbag buoyancy ball 10 is fixed by clamps to ensure buoyancy stability, realizing integrated control of water vapor separation and automatic drainage of the gas storage tank.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
