Therefore, air storage tanks generally have a water drain switch.

[0003] Existing gas tanks require personnel to drain water at regular intervals, or solenoid valves to automatically drain water at regular intervals. However, the scheduled drainage cannot automatically drain water according to the water volume. When the water volume is very low, it will continue to automatically drain water, resulting in excessive waste of compressed gas. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 A high-strength compressed air storage tank comprises a shell 1 and legs 2, wherein a plurality of legs 2 are respectively fixedly connected to the lower end surface of the shell 1, and the shell 1 is made of high-strength steel, so the strength of the device is very high;

[0023] A control component is arranged in the shell 1, and the control component includes a sealing plug 4, a counterweight 5, a buoyancy plate 6, a control box 7, a wedge block 8, and an L-shaped block 9. A drainage bucket 3 is fixedly connected to the bottom of the shell 1, and the sealing plug 4 is slidably connected to the drainage bucket 3. As the gas is continuously injected into the storage tank, the liquid level at the bottom of the shell 1 becomes higher and higher. The counterweight 5 is fixedly connected to the upper end surface of the sealing plug 4, and the buoyancy plate 6 is fixedly connected to the upper end surface of the counterweight 5. The sealing plug 4 seals the drainage bucket 3, and the counterweight 5 applies a certain pressure to the buoyancy plate 6, so that when the liquid level just rises and contacts the buoyancy plate 6, the buoyancy plate 6 will not rise immediately, and the liquid The body will prevent gas leakage before it flows out. The control box 7 is fixedly connected to the side wall of the shell 1. The side wall of the control box 7 is provided with a slide groove. The wedge block 8 is fixedly connected in the slide groove. The side wall of the wedge block 8 has a certain inclination angle. An extrusion spring 14 is fixedly connected between the wedge block 8 and the control box 7. The wedge block 8 slides horizontally in the slide groove. The side wall of the control box 7 is provided with a slide. The L-shaped block 9 is slidably connected in the slide. The L-shaped block 9 slides up and down in the slide. The side wall of the wedge block 8 is provided with a lock hole. The L-shaped block 9 is slidably connected in the lock hole. The upper end surface of the L-shaped block 9 is fixedly connected to the limit rod 12. The control box A limiting groove is provided on the side wall of 7, and the limiting rod 12 is slidably connected in the limiting groove. A reset spring 13 is fixedly connected between the L-shaped block 9 and the control box 7. Under normal conditions, the lower end of the L-shaped block 9 is stuck in the lock hole of the side wall of the wedge block 8 to limit the wedge block 8. The wedge block 8 is stored in the control box 7. The buoyancy plate 6 will not contact the wedge block 8 when it rises. When the buoyancy plate 6 rises and contacts the L-shaped block 9, it drives the L-shaped block 9 to rise, and the limitation on the wedge block 8 is released. The wedge block 8 moves forward under the action of the extrusion spring 14 and moves to the bottom of the buoyancy plate 6. At this time, the sealing plug 4 just leaves the drainage bucket 3. The liquid flows out from the drainage bucket 3. At this time, the buoyancy is slightly smaller than the gravity of the counterweight block 5 and the buoyancy plate 6, so the wedge block 8 cannot be pushed. As the liquid level continues to drop, when the elastic force of the extrusion spring 14 is smaller than the horizontal component of the buoyancy plate 6 on the wedge block 8, the wedge block 8 is retracted inward into the control box 7. The L-shaped block 9 slides into the locking block under the action of the reset spring 13, and the wedge block 8 is re-locked. The buoyancy plate 6 moves downward to drive the sealing plug 4 to move downward, and the drainage bucket 3 is re-sealed. Water no longer flows out. At this time, there is still a certain amount of liquid left in the tank. The liquid will prevent the gas from leaking before it flows out, and no compressed gas will be wasted.

[0024] The control assembly also includes a fixed block 10 and a slide bar 11. The fixed block 10 is fixedly connected to the side wall of the shell 1. The two slide bars 11 are fixedly connected to the upper end surface of the buoyancy plate 6. The slide bar 11 is slidably connected in the fixed block 10. The slide bar 11 limits the buoyancy plate 6 so that it can go straight up and down without deviation when floating, avoiding the buoyancy plate 6 from being able to align with the control box 7 and the sealing plug 4 from being able to align with the drainage bucket 3 after the horizontal position moves.

[0025] A rotating rod 15 is rotatably connected inside the sealing plug 4, and an impeller blade 16 is fixedly connected to the rotating rod 15. A stirring paddle 17 is fixedly connected to the outer surface of the rotating rod 15. A scraper is provided on the side wall of the stirring paddle 17. When the liquid flows outward, the impeller blade 16 is driven to rotate, and the impeller blade 16 drives the rotating rod 15 and the stirring paddle 17 to rotate. The scraper on the stirring paddle 17 scrapes off the impurities attached to the drainage bucket 3 to prevent the impurities from adhering to the drainage bucket 3, thereby preventing the sealing plug 4 from losing the sealing effect, thereby ensuring the airtightness of the device.

[0026] In the utility model, when a certain amount of water condenses in the tank body during use, the water will gather at the bottom of the tank, and the liquid level will continue to rise and overflow the buoyancy plate 6. The buoyancy plate 6 floats up under the action of buoyancy and drives the counterweight block 5 and the sealing plug 4 to move up. At this time, the sealing plug 4 still seals the drainage bucket 3. The water level continues to rise and drives the buoyancy plate 6 to rise and contact the L-shaped block 9. The buoyancy plate 6 drives the L-shaped block 9 to move up, so that the L-shaped block 9 releases the limit on the wedge block 8. The wedge block 8 is pushed out of the control box 7 under the action of the extrusion spring 14. At this time, the sealing plug 4 is separated from the drainage bucket 3, and water flows out of the drainage bucket 3. The water flow drives the impeller blade 16 to rotate, and the impeller blade 16 drives the rotating rod 15 and the stirring paddle 17 to rotate. The scraper on the stirring paddle 17 removes the impurities attached to the drainage bucket 3. The quality is scraped off to prevent impurities from adhering to the drainage bucket 3 and to avoid the sealing plug 4 from losing its sealing effect, thereby ensuring the airtightness of the device. At the same time, as the liquid level drops, the buoyancy plate 6 moves down and contacts the wedge block 8. At this time, the buoyancy is slightly smaller than the gravity of the counterweight block 5 and the buoyancy plate 6 itself, so the wedge block 8 cannot be pushed. As the water level continues to drop, the buoyancy also continues to decrease. When the wedge block 8 cannot support the buoyancy plate 6, the wedge block 8 is retracted into the control box 7. The buoyancy plate 6 moves down to drive the sealing plug 4 to move down, and the drainage bucket 3 is resealed. The water no longer flows out, realizing the function of automatic drainage according to the amount of water. At this time, there is still a certain amount of water in the tank body, so the compressed gas will not be wasted during the drainage process, avoiding excessive drainage to reduce the pressure in the tank body.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
