Description

Technical Field

[0001] The present invention relates to the technical field of gas water seal equipment, in particular to a U-shaped bidirectional gas water seal structure. Background Art

[0002] Coal gas is a combustible gas produced by processing coal. Depending on the processing method, gas properties, and application, it can be categorized as water gas, semi-water gas, air gas, coke oven gas, and blast furnace gas. As a major byproduct energy source, coal gas is increasingly used in industrial enterprises. Furthermore, the utilization of byproduct gas is becoming increasingly important from the perspectives of energy conservation and environmental protection, leading to the continuous development and application of various new equipment. The "Safety Regulations for Coal Gas in Industrial Enterprises" (GB6222-2005) mandates that reliable isolation devices be installed in areas subject to frequent maintenance. A water seal is a reliable isolation device only when used in series with other isolation devices.

[0003] Although there are gas water seal devices, existing industrial enterprises mostly design gas water seals by opening a hole on the inlet side of the gas pipeline to install a water seal inlet pipe, and opening a hole on the outlet side to install a water seal overflow pipe, and using the water seal water replenishment height to seal the gas. When gas is flowing normally in the pipeline, but the water supply pipe fails and the water is cut off, gas may leak from the water replenishment port of the water seal overflow pipe, causing a safety accident. Summary of the Invention

[0004] The object of the present invention is to provide a U-shaped bidirectional gas water seal structure to solve the problems raised in the above background technology.

[0006] The inner wall of the U-shaped water seal pipe is provided with a downward pressure groove, and the inner wall of the U-shaped water seal pipe is provided with a sliding groove.

[0007] The water inlet and outlet mechanism includes a drainage pump, which is connected to a U-shaped water seal pipe through a water suction pipe. The water suction pipe is connected to a drainage valve. The water outlet of the drainage pump is connected to a water outlet pipe. The water inlet pipe is connected to an inlet pump. An induction groove is provided on the surface of the U-shaped water seal pipe, and a sensor is fixedly connected to the inner wall of the induction groove.

[0008] There are two water inlet pipes, which are connected via a connecting pipe.

[0009] The sealing mechanism includes a threaded rod, the end of which is rotatably connected to a support ring, and the two ends of the support ring are fixedly connected to the inner wall of the U-shaped water seal tube; one end of the transmission rod extends into the U-shaped water seal tube and is coaxially fixed to the threaded rod; A threaded ring is threadedly connected to the threaded rod, and a limiting elastic rod is provided between the threaded ring and the inner wall of the U-shaped water seal pipe; the threaded ring is fixedly connected to the passive frame, and the threaded ring is hinged with a merging rod, which is hinged to the sealing plate.

[0010] A sealing gasket is fixedly connected to the surface of the sealing plate.

[0011] The isolation mechanism includes a lower push rod, the lower push rod is hinged with a sliding frame, the sliding frame is fixedly connected to the push rod, the lower push rod is hinged with the passive frame, and the sliding frame is slidably connected to the inner wall of the lower pressure groove; The isolation plate is hinged with a driven frame, and the driven frame is fixedly connected to the inner wall of the U-shaped water seal pipe; an elastic plate is connected between the two isolation plates, and the push rod is fixedly connected to the elastic plate.

[0012] It also includes a support rod, the lower end of which is fixedly connected to a support slider, which is slidably connected to the sliding groove; the upper end of the support rod contacts the bottom of one of the isolation plates; and a support elastic rod is provided between the support rod and the U-shaped water seal pipe.

[0013] The present invention has the following beneficial effects: The present invention is provided with a water inlet and outlet mechanism. When the water in the U-shaped water seal pipe needs to be replaced, the drain valve is first opened, and then the drain pump is started to extract the water inside the U-shaped water seal pipe through the suction pipe, and then the water is discharged through the outlet pipe. When the water inside the U-shaped water seal pipe is lower than the sensor, the sensor is triggered and the motor is started. When water needs to be added, the water inlet valve is first opened and then the water inlet pump is started. Water is added into the U-shaped water seal pipe through the water inlet pipe. Two water inlet pipes are provided, and water can be added at the same time, so that the U-shaped water seal pipe is effectively and quickly added with water, and the water adding efficiency is improved.

[0014] The present invention provides a sealing mechanism, which drives the transmission rod to rotate when the motor is started, and drives the threaded rod to rotate when the transmission rod rotates. When the threaded rod rotates, the threaded ring moves on the surface of the threaded rod toward the sensor, and squeezes the limiting elastic rod when the threaded rod moves. When the threaded ring moves, it drives the passive frame to move toward the sensor, and when the threaded ring moves, it pulls the merging rod to move toward the limiting elastic rod. When the merging rod moves, it pulls the sealing plate toward each other, and when the sealing plate moves, it pushes the sealing gasket toward each other, and when the sealing plate moves, it pulls the passive contraction rod to extend toward each other. The sealing gasket is squeezed by the sealing plate, which can effectively prevent gas from entering the pipeline when the water is replaced in the U-shaped water seal pipe, thereby preventing gas leakage.

[0015] When the support rod moves downward, it squeezes the supporting elastic rod downward and limits the position when it reaches a certain position. It can effectively isolate the coal balls remaining in the U-shaped water seal pipe when replacing water in the U-shaped water seal pipe, and prevent leakage at the water supply port of the water seal overflow pipe.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1 - Figure 8 As shown, the present invention is a U-shaped bidirectional gas water seal structure, comprising a U-shaped water seal pipe 1, a support plate 2 fixedly connected to the surface of the U-shaped water seal pipe 1, a motor 3 fixedly connected to the surface of the support plate 2, a transmission rod 4 fixedly connected to the output end of the motor 3, which drives the transmission rod 4 to rotate when the motor 3 is started, a sealing connection ring 5 fixedly connected to both ends of the U-shaped water seal pipe 1, a force block 6 fixedly connected to the inner wall of the U-shaped water seal pipe 1, and further comprising; The water inlet and outlet mechanism 10 includes a water inlet pipe 15, which is provided with a water inlet valve 16. When water needs to be added, the water inlet valve 16 is first opened and then the water inlet pump 18 is started to add water into the interior of the U-shaped water seal pipe 1 through the water inlet pipe 15.

[0022] The sealing mechanism 30 comprises at least two sealing plates 37, each slidably connected to the sealing connection ring 5, to which a corresponding fixing ring 38 is fixed. When the merging rod 36 moves, it pulls the sealing plates 37 toward each other. A passive retractable rod 39 is provided between the sealing plates 37 and the sealing connection ring 5. Its ends are fixedly connected to the sealing plates 37 and the sealing connection ring 5, respectively.

[0023] Isolation mechanism 50 comprises two isolation plates 55. An elastic plate 54 drives isolation plates 55 to rotate downward. Seal holes are defined on the surfaces of isolation plates 55. When one side of isolation plate 55 contacts force-bearing block 6, the two isolation plates 55 merge together to provide isolation. A sealing ring gasket 56 is fixedly attached to the inner wall of the sealing hole.

[0024] There are two motors 3, which are symmetrically arranged on the surface of the support plate 2. A downward pressure groove is provided on the inner wall of the U-shaped water seal tube 1. There are two sealing connection rings 5, which are symmetrically arranged with the support plate 2 as the center. A sliding groove is provided on the inner wall of the U-shaped water seal tube 1.

[0025] The water inlet and outlet mechanism 10 includes a drain pump 11. The water inlet of the drain pump 11 is connected to a water pumping pipe 12, and the water pumping pipe 12 is provided with a drain valve 13. When the water in the U-shaped water seal pipe 1 needs to be replaced, the drain valve 13 is first opened, and the water outlet of the drain pump 11 is connected to a water outlet pipe 14, through which the water is discharged.

[0026] The water inlet pipe 15 is connected to a water inlet pump 18. An induction groove is provided on the surface of the U-shaped water seal pipe 1. A sensor 19 is fixedly connected to the inner wall of the induction groove. Two water inlet pipes 15 are provided, and water can be added at the same time, effectively and quickly adding water to the U-shaped water seal pipe 1 and improving the water adding efficiency.

[0027] The two water inlet pipes 15 are connected through a connecting pipe 17, and the end of the water inlet pipe 15 is connected to the U-shaped water seal pipe 1. The water extraction pipe 12 is connected to the U-shaped water seal pipe 1. The drainage pump 11 is started to extract the water inside the U-shaped water seal pipe 1 through the water extraction pipe 12.

[0028] One end of the sensor 19 away from the sensing groove is fixedly connected to the motor 3. When the water inside the U-shaped water seal pipe 1 is lower than the sensor 19, the sensor 19 is triggered and the motor 3 is started.

[0029] The sealing mechanism 30 includes a threaded rod 31. The transmission rod 4 extends into the U-shaped water seal tube 1 and is coaxially fixedly connected to the threaded rod 31. When the transmission rod 4 rotates, it also drives the threaded rod 31 to rotate. The end of the threaded rod 31 is rotatably connected to the support ring 32. The two ends of the support ring 32 are fixedly connected to the inner wall of the U-shaped water seal tube 1.

[0030] The surface of the threaded rod 31 is threadedly connected to a threaded ring 33, and the surface of the threaded ring 33 is fixedly connected to a limiting elastic rod 34, which squeezes the limiting elastic rod 34 when the threaded ring 33 moves. The surface of the threaded ring 33 is fixedly connected to a passive frame 35, which drives the passive frame 35 to move toward the direction of the sensor 19 when the threaded ring 33 moves. A merging rod 36 is hinged to the threaded ring 33, and the end of the merging rod 36 away from the threaded ring 33 is hinged to the sealing plate 37. The surface of the sealing plate 37 is fixedly connected to a sealing gasket 40, which pushes the sealing gasket 40 to move in a direction close to each other when the sealing plate 37 moves. The squeezing of the sealing gasket 40 by the sealing plate 37 can effectively prevent gas from entering the pipeline when the water in the U-shaped water seal pipe 1 is replaced, thereby preventing gas leakage.

[0031] The end of the limiting elastic rod 34 away from the threaded ring 33 is fixedly connected to the inner wall of the U-shaped water seal pipe 1. When the threaded ring 33 moves, it pulls the merging rod 36 toward the limiting elastic rod 34. When the threaded rod 31 rotates, the threaded ring 33 moves on the surface of the threaded rod 31 toward the sensor 19.

[0032] When the sealing plate 37 moves, the passive contraction rod 39 is pulled to extend in a direction of approaching each other, and the surface of the sealing plate 37 can contact the end of the U-shaped water seal pipe 1.

[0033] The isolation mechanism 50 includes a lower push rod 51. When the passive frame 35 moves, the lower push rod 51 is pushed downward. The end of the lower push rod 51 is hinged to a sliding frame 52, and a push rod 53 is fixedly connected to the sliding frame 52. The sealing ring gasket 56 on the isolation plate 55 squeezes and seals the push rod 53.

[0034] The end of the push rod 53 away from the sliding frame 52 is fixedly connected to the elastic plate 54. When the push rod 53 moves, the elastic plate 54 is pushed downward. The isolation plate 55 is hinged to the driven frame 57. The end of the driven frame 57 away from the isolation plate 55 is fixedly connected to the inner wall of the U-shaped water seal pipe 1.

[0035] A support rod 58 is provided at the bottom of one of the isolation plates 55, contacting the support plate. A support slider 59 is fixedly connected to the end of the support rod 58 away from the isolation plate 55. When the support rod 58 moves downward, it pushes the support slider 59 downward along the inner wall of the sliding groove. A support elastic rod 60 is fixedly connected to the bottom of the support rod 58. As the support rod 58 moves downward, it squeezes the support elastic rod 60 downward, limiting its position when it reaches a certain position. This effectively isolates any residual gas inside the U-shaped water seal pipe 1 when the water is replaced, preventing it from leaking into the water supply port of the water seal overflow pipe.

[0036] The end of the lower push rod 51, away from the sliding frame 52, is hinged to the passive frame 35. When the lower push rod 51 moves downward, it pushes the sliding frame 52 to slide downward along the inner wall of the lower pressure groove. The ends of the elastic plate 54 are fixedly connected to the bottoms of the two isolation plates 55. The sliding frame 52 is slidably connected to the inner wall of the lower pressure groove, and when the sliding frame 52 slides downward, it drives the push rod 53 downward. The end of the supporting elastic rod 60, away from the support rod 58, is fixedly connected to the inner wall of the U-shaped water seal pipe 1. When the isolation plates 55 rotate downward, they push the support rod 58 downward.

[0037] During use, when the water in the U-shaped water seal pipe 1 needs to be replaced, the drain valve 13 is first opened, and then the drain pump 11 is started to extract the water inside the U-shaped water seal pipe 1 through the water extraction pipe 12, and then the water is discharged through the water outlet pipe 14. When water needs to be added, the water inlet valve 16 is first opened and then the water inlet pump 18 is started, and then water is added to the interior of the U-shaped water seal pipe 1 through the water inlet pipe 15. There are two water inlet pipes 15 so that water can be added simultaneously.

[0038] When the water level inside the U-shaped water seal tube 1 drops below the level of the sensor 19, the sensor 19 is triggered and the motor 3 is started. When the motor 3 is started, it drives the transmission rod 4 to rotate, which in turn drives the threaded rod 31 to rotate. As the threaded rod 31 rotates, the threaded ring 33 moves on the surface of the threaded rod 31 toward the sensor 19. As the threaded ring 33 moves, it squeezes the limit elastic rod 34, which in turn drives the passive frame 35 toward the sensor 19.

[0039] When the threaded ring 33 moves, it pulls the merging rod 36 to move in the direction of the limiting elastic rod 34. When the merging rod 36 moves, it pulls the sealing plate 37 to move in the direction of approaching each other. When the sealing plate 37 moves, the sealing gasket 40 thereon moves in the direction of approaching each other.

[0040] The movement of the sealing plate 37 pulls the passive retractable rod 39 toward each other, extending it. The movement of the passive frame 35 also pushes the lower push rod 51 downward. This downward movement of the lower push rod 51 pushes the sliding frame 52 downward along the inner wall of the lower pressure groove. The downward movement of the sliding frame 52 also drives the push rod 53 downward. The movement of the push rod 53 also pushes the deformed elastic plate 54 downward, causing the elastic plate 54 to rotate downward. When one side of the isolation plate 55 contacts the load-bearing block 6, the two isolation plates 55 merge, effectively isolating the components.

[0041] The sealing ring gasket 56 on the isolation plate 55 squeezes and seals the push rod 53. When the isolation plate 55 rotates downward, it pushes the support rod 58 downward. When the support rod 58 moves downward, it pushes the support slider 59 to slide downward on the inner wall of the sliding groove. When the support rod 58 moves downward, it squeezes the support elastic rod 60 downward, and stops when it reaches a certain position.
