Technical Field

[0001] This utility model relates to the field of gas storage tank technology, and in particular to a gas storage tank sewage discharge device. Background Technology

[0002] Gas tanks are devices specifically designed to store gases and also serve to stabilize system pressure. Based on the pressure they can withstand, gas tanks can be classified as high-pressure gas tanks, low-pressure gas tanks, and atmospheric pressure gas tanks.

[0003] A sewage discharge device for a gas storage tank is disclosed in CN219243329U. This application includes a gas storage tank, an exhaust pipe fixedly installed on one side of the tank, a control valve fixedly installed on the side of the exhaust pipe near the tank, a pressure gauge installed on the side of the tank away from the exhaust pipe, a connector rotatably installed on the side of the exhaust pipe away from the tank, an inlet pipe threaded onto one side of the inner wall of the connector, a filter box fixedly installed on the side of the inlet pipe away from the connector, an outlet pipe fixedly installed on the side of the filter box away from the inlet pipe, an outlet cover threaded onto the side of the outlet pipe away from the filter box, a connecting block fixedly installed on the side of the filter box near a fixed rod, and a fixing bolt installed on the side of the connecting block away from the filter box.

[0004] The aforementioned device removes impurities from the exhaust gas through the filter box, ensuring the exhaust gas is free of contaminants. However, during the filtration process, as impurities accumulate on the filter screen, its ventilation efficiency decreases. At this point, workers need to replace the filter screen promptly to maintain filtration effectiveness. Unfortunately, the device currently relies on manual judgment of the filter screen's ventilation rate. This means workers cannot directly and accurately observe changes in the filter screen's ventilation efficiency, leading to a failure to quickly detect and replace the filter screen when its ventilation efficiency significantly decreases, thus affecting the normal exhaust operation of the gas storage tank. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-6 A gas storage tank sewage discharge device includes an exhaust tank 1, an exhaust pipe 2 fixedly connected to the bottom surface of the exhaust tank 1, a valve 3 installed inside the exhaust pipe 2, a connecting horizontal pipe 4 fixedly connected to the inner wall of the exhaust pipe 2, a sewage discharge box 5 fixedly connected to the right end of the connecting horizontal pipe 4, and a filter plate 10 placed inside the sewage discharge box 5. The valve 3 can be used to control whether the exhaust pipe 2 exhausts gas. After the gas enters the sewage discharge box 5, it can be filtered by the filter plate 10 to remove impurities or dirt.

[0019] A connecting rod 6 is fixedly connected to the bottom surface of the exhaust tank 1. The bottom end of the connecting rod 6 is fixedly connected to the upper surface of the sewage tank 5. By using the connecting rod 6, the sewage tank 5 and the exhaust tank 1 can be connected.

[0020] The sewage tank 5 has a front cover 8 inside. There are two hinges 7 on the front of the sewage tank 5. The front cover 8 is connected to the sewage tank 5 through the two hinges 7. There is a pull rod on the front of the front cover 8, which can be pulled to rotate the front cover 8. Pulling the pull rod can open the front cover 8.

[0021] The front of the sewage tank 5 is provided with a limiting mechanism 9. The limiting mechanism 9 includes a support shaft 905. The rear end of the support shaft 905 is fixedly connected to the sewage tank 5. A support plate 904 is rotatably connected to the outer surface of the support shaft 905. By using the support shaft 905, the rotation of the support plate 904 can be supported. The support plate 904 can rotate about the center point of the cross section of the support shaft 905.

[0022] The inner wall of the support plate 904 is threadedly connected to a threaded rotating rod 902. The front end of the threaded rotating rod 902 is fixedly connected to a rotating plate 901, and the rear end of the threaded rotating rod 902 is fixedly connected to an abutment plate 903. The back of the abutment plate 903 abuts against the front cover 8. By rotating the rotating plate 901, the threaded rotating rod 902 can be rotated, so that the abutment plate 903 is no longer pressed against the front cover 8. Then the support plate 904 can be rotated so that the abutment plate 903 no longer obstructs the front cover 8, and the front cover 8 can be opened to replace the filter plate 10.

[0023] A judgment box 11 is fixedly connected to the right side of the front cover 8. A rotating shaft 13 is rotatably connected to the inner bottom wall of the judgment box 11. The rotating shaft 13 passes through the upper surface of the judgment box 11 and extends to the top of the judgment box 11. The outer surface of the rotating shaft 13 is rotatably connected to the inner top wall of the judgment box 11. A judgment mark 14 is fixedly connected to the top of the rotating shaft 13. A wind-receiving plate 12 is fixedly connected to the outer surface of the rotating shaft 13. Figure 4 As shown, the air receiving plate 12 is located at an eccentric position between the ventilation holes of the sewage box 5 and the judgment box 11, making it easier for the air to blow the air receiving plate 12 to rotate. When the air receiving plate 12 rotates, it can drive the rotating shaft 13 and the judgment mark 14 to rotate, making it convenient for workers to judge whether the air flow is affected by the filter plate 10 with dirt attached.

[0024] An elliptical block 15 is fixedly connected to the outer surface of the wind-receiving plate 12. A blocking mechanism 16 is provided on the front side of the elliptical block 15. The blocking mechanism 16 includes a sliding panel 1601. An external connecting pipe 17 is fixedly connected to the right side of the judgment box 11. The outer surfaces of the elliptical block 15 and the sliding panel 1601 are relatively smooth. When the elliptical block 15 rotates, it will slightly touch the sliding panel 1601 to slow down the rotation speed of the shaft 13 and prevent the wind-receiving plate 12 and the shaft 13 from rotating rapidly even with a slight breeze, which would affect the worker's judgment.

[0025] A support rod 1602 is slidably connected to a slot on the front of the sliding panel 1601. The front end of the support rod 1602 is fixedly connected to the inner wall of the judgment box 11. Figure 6 As shown, the front of the sliding panel 1601 has a slot in which the support rod 1602 can be inserted. When the elliptical block 15 touches the bottom sliding panel 1601, the sliding panel 1601 will move forward, and the support rod 1602 will be inserted into a deeper position inside the sliding panel 1601.

[0026] A spring 1603 is wound around the outer surface of the support rod 1602. The front and rear ends of the spring 1603 are fixedly connected to the sliding panel 1601 and the judgment box 11, respectively. By using the elastic force of the spring 1603, the sliding panel 1601, which is pushed by the elliptical block 15, can be reset, so that the sliding panel 1601 can be ready to be touched by the elliptical block 15 again.

[0027] Working principle: Opening valve 3 allows the gas inside exhaust tank 1 to enter the interior of sewage tank 5 through exhaust pipe 2 and connecting horizontal pipe 4. Under the filtering action of filter plate 10, the dirt attached to the gas can be filtered. After the gas enters the interior of judgment box 11, it will blow the air receiving plate 12 to rotate. By observing the rotation of judgment mark 14, the worker can quickly and intuitively judge the ventilation efficiency of filter plate 10. The air receiving plate 12 can drive the rotating shaft 13 and the elliptical block 15 to rotate. When the elliptical block 15 rotates, it will periodically touch the sliding panel 1601. The sliding panel 1601 will move forward and retract part of the support rod 1602 into the interior of the sliding panel 1601. Under the elastic force of the spring 1603, the sliding panel 1601 can be reset to prepare for the next impact. The contact between the elliptical block 15 and the sliding panel 1601 can slow down the rotation of the rotating shaft 13, increase the difficulty of rotating the judgment mark 14, and make it more difficult to blow the air receiving plate 12. This prevents a small breeze from causing the judgment mark 14 to rotate many times, making it difficult for workers to judge the ventilation efficiency of the filter plate 10.
