Description

Technical Field

[0001] The utility model relates to the technical field of compressed air tanks, in particular to an automatic drainage device for a compressed air tank used in a power plant. Background Art

[0002] Compressed air tanks are devices that can store compressed gas. Usually, they are made of steel and can withstand high-pressure gas. They are widely used in various fields such as industry, construction, agriculture, transportation and aviation. However, compressed air tanks used in power plants will have some liquid accumulation, so the liquid inside the compressed air tanks needs to be discharged.

[0003] When draining existing compressed air tanks, the valve needs to be opened manually, and the valve needs to be closed manually after all the liquid is drained. However, manual switching will cause internal gas leakage. Once there is flammable and explosive gas in the tank, if it is not closed in time, it will cause the risk of explosion. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic drainage device for a compressed air tank used in a power plant, so as to solve the problems raised in the above-mentioned background technology.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution: Figure 1-Figure 5The shown embodiment is an automatic drainage device for a compressed air tank for a power plant, comprising a tank body 1, a drain pipe 2 fixedly connected to the inner side of the tank body 1 near the bottom, a drain outlet 3 opened on the inner side of the drain pipe 2 near the bottom, a plurality of drain outlets 3 arranged in a circular array outside the drain pipe 2, a sliding rod 4 slidably connected to the inside of the drain pipe 2, a suspension plate 5 fixedly connected to the top of the sliding rod 4, a limiting assembly arranged inside the sliding rod 4 and the suspension plate 5, the limiting assembly comprising a positioning rod 6, the positioning rod 6 fixedly connected to the inner side of the tank body 1 near the top, the sliding rod 4 and the suspension plate 5 slidably connected to the outside of the positioning rod 6, and a limiting plate 8 fixedly connected to the outside of the positioning rod 6 near the top of the suspension plate 5.

[0020] During operation, after gas is injected into the tank body 1, liquid will precipitate under the high-pressure environment inside the tank body 1, and liquid will accumulate inside the tank body 1 under long-term use. When the liquid reaches the bottom of the suspension plate 5, the liquid level continues to rise, which will drive the suspension plate 5 and the sliding rod 4 to slide along the outside of the positioning rod 6. The limit plate 8 can prevent the sliding rod 4 from detaching from the inside of the drain pipe 2, and the sliding rod 4 will leave the inside of the drain pipe 2. In this way, the liquid will be discharged along the drain outlet 3, and the impact force of the water flow will prevent the sliding rod 4 and the suspension plate 5 from falling back. When the impact force of the liquid is lost, the sliding rod 4 will re-seal the drain outlet 3, achieving the effect of fast and automatic drainage, solving the problem of manual opening and closing of the valve in the past, which resulted in failure to close in time and caused the risk of explosion, and improving the safety during drainage.

[0021] See also Figure 2 and Figure 3 In the figure, the limit plate 8 is fixedly connected to the side of the suspension plate 5, and the end of the spring 7 away from the limit plate 8 is fixedly connected to the top of the suspension plate 5. The spring 7 is sleeved on the outside of the positioning rod 6. A pulling assembly is provided at the bottom of the sliding rod 4. The pulling assembly includes a pull rope 11, which is fixedly connected to the bottom of the sliding rod 4. The end of the pull rope 11 away from the sliding rod 4 is fixedly connected to a pull ring 12.

[0022] During operation, after the liquid is discharged, the impact force of the drain outlet 3 is not enough to support the sliding rod 4 and the suspension plate 5. At this time, the spring 7 will push the sliding rod 4 and the suspension plate 5 to reset, thus achieving a stable manual closing effect. If the internal pressure of the tank body 1 is too large and the spring 7 cannot push the suspension plate 5 to reset, you can pull the pull ring 12, thereby driving the pull rope 11 to make the sliding rod 4 slide along the inside of the drain pipe 2, and manually close the drain outlet 3, thereby improving the overall safety of use and the automatic closing effect.

[0023] See also Figure 1 、 Figure 2 and Figure 3In the figure, an air inlet 9 is fixedly connected to the outside of the tank body 1 near the top, and an exhaust port 10 is fixedly connected to the side of the outside of the tank body 1 away from the air inlet 9. The air inlet 9 and the exhaust port 10 are connected to the interior of the tank body 1. A support assembly is provided at the bottom of the tank body 1, and the support assembly includes a support plate 13. The support plate 13 is fixedly connected to the bottom of the tank body 1, and the pull rope 11 is slidably connected to the inside of the support plate 13. Support legs 14 are fixedly connected to the outside of the bottom of the tank body 1, and there are multiple groups of support legs 14 in a circular array at the bottom of the tank body 1.

[0024] During operation, gas is injected into the tank body 1 through the air inlet 9 to pressurize it. At this time, the pressurized gas can be discharged through the exhaust port 10. When draining, if manual closure is required, the pull ring 12 can be pulled to drive the pull rope 11 to slide along the outside of the support plate 13, thereby ensuring the smoothness of the pulling of the pull rope 11, and the support legs 14 can support the tank body 1.

[0025] Working principle: After the gas is injected into the tank body 1, liquid will precipitate under the high-pressure environment inside the tank body 1, and liquid will accumulate inside the tank body 1 under long-term use. When the liquid reaches the bottom of the suspension plate 5, the liquid level continues to rise, which will drive the suspension plate 5 and the sliding rod 4 to slide along the outside of the positioning rod 6. The limit plate 8 can prevent the sliding rod 4 from detaching from the inside of the drain pipe 2, and the sliding rod 4 will leave the inside of the drain pipe 2, so that the liquid will be discharged along the drain outlet 3, and the impact force of the water flow will prevent the sliding rod 4 and the suspension plate 5 from falling back. When the impact force of the liquid is lost, the sliding rod 4 will re-seal the drain outlet 3, achieving the effect of fast and automatic drainage, solving the problem of manual opening and closing the valve in the past, which resulted in failure to close in time and caused the risk of explosion, and improving the safety during drainage. After the liquid is discharged, the impact force of the drain outlet 3 is not It is enough to support the sliding rod 4 and the suspension plate 5. At this time, the spring 7 will push the sliding rod 4 and the suspension plate 5 to reset, thus achieving a stable manual closing effect. If the internal pressure of the tank body 1 is too large and the spring 7 cannot push the suspension plate 5 to reset, the pull ring 12 can be pulled to drive the pull rope 11 to make the sliding rod 4 slide along the inside of the drain pipe 2, and the drain outlet 3 is manually closed, which improves the overall safety of use and the automatic closing effect. Gas is injected into the tank body 1 through the air inlet 9 to increase the pressure. At this time, the pressurized gas can be discharged through the exhaust port 10. When draining, if manual closure is required, the pull ring 12 can be pulled to drive the pull rope 11 to slide along the outside of the support plate 13, thereby ensuring the smoothness of the pulling of the pull rope 11, and the support legs 14 can support the tank body 1.
