Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a structure for unblocking and preventing clogging of a bottom drainage pipe with a water seal. Background Technology

[0002] Coke oven gas from coking plants, blast furnace gas from steel plants, converter gas, and gas produced by coal gasification units all contain a significant amount of water. Accumulated water in pipelines increases the load on pipeline supports and reduces the flow area, affecting gas delivery. Therefore, it is necessary to drain the water from the pipelines promptly. To ensure timely drainage without gas leakage, a gas pipeline drainer is required. Water seals are widely used in the main gas pipelines of steel enterprises. Water seals are often applied after butterfly valves, and water injection reliably shuts off the gas supply. Because water accumulates at the bottom of the water seal during normal gas flow, a drainer needs to be installed at the bottom to drain this water. The water in the water-sealed pipeline flows into the drainer through a vertical drainage pipe at the bottom of the pipeline. Gas also enters the drainer simultaneously. Since the gas pressure is lower than the static pressure of the water in the drainer, the gas is blocked by the water column and cannot flow forward. The water in the gas pipeline flows into the drainer and is discharged through an overflow pipe.

[0003] When steel plant gas pipelines transport gas, they often carry wastewater, tar, and other impurities. When passing through V-shaped or U-shaped water seals, these impurities accumulate at the bottom of the water seal, clogging the drain pipe and preventing proper drainage. This results in condensation of the gas at the bottom of the water seal; excessive condensation can completely block the seal, preventing gas flow and impacting production. Existing methods for clearing blockages at the bottom of the water seal require cutting off the pipeline at the bottom and performing the work online, posing a safety hazard such as gas leakage. Therefore, to address this hazard and ensure no gas leakage before clearing the pipeline, this invention proposes a structure for clearing and preventing blockages in the drain pipe at the bottom of water seals.

[0015] The technical solution of this utility model embodiment achieves efficient unblocking of the bottom drain pipe of the water seal by setting up a structure of unblocking pipe, nozzle and adjustment component. The unblocking pipe can directly penetrate into the easily blocked area, the nozzle can accurately spray water flow, and the adjustment component can adjust the water flow pressure to make it fluctuate, so that the pressure change of the water flow generates shear force and vibration effect.

[0021] like Figures 1 to 4 As shown, the present invention proposes a structure for unblocking and preventing blockage of the bottom drain pipe of a water seal, comprising: a water seal 1, a first connecting pipe 2 connected to the outer wall of the water seal 1, a primary valve 3 connected to one end of the first connecting pipe 2, a second connecting pipe 4 connected to one end of the primary valve 3, the second connecting pipe 4 being a straight pipe or a 90-degree bend, and the primary valve 3 being able to control the connection between the first connecting pipe 2 and the second connecting pipe 4.

[0022] Furthermore, a dredging pipe 5 is fixedly installed through the second connecting pipe 4. The dredging pipe 5 is a straight pipe or a 45-degree bend, which can be selected according to the second connecting pipe 4 to improve the applicability. A valve 6 is connected to one end of the dredging pipe 5, and a third connecting pipe 7 is connected to one end of the valve 6. The valve 6 can control the opening and closing of the dredging pipe 5 and the third connecting pipe 7. A connector 8 is connected to one end of the third connecting pipe 7, and a nozzle 9 is provided at one end of the dredging pipe 5. The nozzle 9 is easy to connect to water source equipment.

[0023] like Figure 4 and Figure 5 As shown, the unblocking pipe 5 is internally equipped with an adjustment component 10 for regulating the water pressure of the nozzle 9. The adjustment component 10 includes a fixed collar 101 disposed inside the unblocking pipe 5. Multiple support rods 102 are fixedly disposed on the outer wall of the fixed collar 101, and the multiple support rods 102 are arranged in a ring array on the outer wall of the fixed collar 101. One end of the support rods 102 is fixedly connected to the inner wall of the unblocking pipe 5, which can provide stable support for the fixed collar 101. A connecting shaft 103 is movably sleeved on the fixed collar 101, which can make the connecting shaft 103 rotate stably on the fixed collar 101. One end of the connecting shaft 103 is fixedly connected to a connecting rod 17, and one end of the connecting rod 17 is fixedly connected to a locking block 18, which can make the connecting shaft 103 drive the locking block 18 to rotate simultaneously through the connecting rod 17. A turbine 104 is fixedly connected to the lower end of the shaft 103. The turbine 104 can be driven to rotate by the water flow inside the drain pipe 5, thereby providing power to the connecting shaft 103. An adjusting plate 105 is provided at the other end of the connecting shaft 103. The adjusting plate 105 is a disc structure. A connecting block 19 is fixedly provided on the bottom surface of the adjusting plate 105. A slot 20 is opened on the bottom surface of the connecting block 19. The slot 20 can be engaged with the slot block 18, so that the connecting shaft 103 drives the adjusting plate 105 to rotate. Multiple water holes 106 are opened on the upper surface of the adjusting plate 105. The multiple water holes 106 are arranged in a ring array on the upper surface of the adjusting plate 105. A guide collar 21 is fixedly sleeved on the outer wall of the adjusting plate 105. The diameter of the water holes 106 is different, which can adjust the size of the water flow.

[0024] Furthermore, the adjusting assembly 10 also includes a sealing baffle 107 fixedly installed on the inner wall of the unblocking pipe 5. The sealing baffle 107 is located on one side of the adjusting plate 105 and can block the water passage hole 106 on the adjusting plate 105. The upper surface of the sealing baffle 107 is provided with a water outlet hole 108, which can communicate with the water passage hole 106 on the adjusting plate 105, allowing water to flow out from the nozzle 9. The bottom surface of the sealing baffle 107 is fixedly provided with a limiting collar 109. The inner wall of the limiting collar 109 is provided with a guide groove 22. The guide collar 21 is slidably connected to the guide groove 22, which can limit the adjustment plate 105 and ensure the stability of rotation.

[0025] As Figure 2 , Figure 3 and Figure 6 shown, a collar 11 is fixedly sleeved on the outer wall of the dredging pipe 5. Slide grooves 23 are respectively formed on both sides of the collar 11. A plurality of guide frames 12 are fixedly arranged on the outer wall of the collar 11. The guide frames 12 are arranged in a "C" - shaped structure, and the plurality of guide frames 12 are arranged in an annular array on the outer wall of the collar 11. A guide rod 13 is movably penetrated through the guide frame 12. One end of the guide rod 13 is fixedly connected with a limiting block 14. The limiting block 14 can provide a limit for the guide rod 13 to prevent the guide rod 13 from detaching from the guide frame 12. Slide blocks 24 are respectively fixedly arranged on both sides of the limiting block 14. The slide blocks 24 are slidably connected with the slide grooves 23, which can provide guidance for the guide rod 13 to make its movement more stable. The other end of the guide rod 13 is fixedly connected with a fixing block 15. The fixing block 15 is arranged in an arc - shaped structure, and its outer arc surface is provided with anti - slip lines, which can closely adhere to the inner wall of the second communication pipe 4. A spring 16 is sleeved on the outer wall of the guide rod 13. One end of the spring 16 is fixedly connected with the guide frame 12, and the other end of the spring 16 is fixedly connected with the limiting block 14. The spring 16 can provide a thrust for the fixing block 15 to make the fixing block 15 stably fit with the inner wall of the second communication pipe 4.

[0026] The working principle of this embodiment is as follows: First, select the installation of the corresponding dredging pipe 5 according to the second communication pipe 4 on the water seal 1. When the second communication pipe 4 is a bent pipe, select the dredging pipe 5 as a straight pipe. Align one end of the dredging pipe 5 with the preset through - hole at the bending part of the second communication pipe 4, and slowly push the dredging pipe 5 into the interior of the second communication pipe 4. After pushing it to the appropriate position, seal - weld the alignment at the through - hole.

[0027] When the second communication pipe 4 is a straight pipe, select the dredging pipe 5 as a bent pipe. Make the bent part of the dredging pipe 5 insert into the interior from the preset through - hole on the second communication pipe 4 at an appropriate angle. After inserting it to the appropriate position, seal - weld the through - hole.

[0028] Next, connect connector 8 to the external water source equipment and open valve 6. The water will then flow through the third connecting pipe 7 and valve 6 into the unblocking pipe 5. The water flow in the unblocking pipe 5 will drive the turbine 104 to rotate. The turbine 104 will drive the connecting shaft 103 to rotate. The connecting shaft 103 will cooperate with the slot 20 of the connecting block 19 through the connecting rod 17 and the locking block 18, driving the adjusting plate 105 to rotate within the limiting collar 109. Because the water passage holes 106 on the regulating plate 105 have different diameters, during its rotation, the water passage holes 106 with different diameters will connect with the water outlet holes 108 of the sealing baffle 107. This causes a sudden pressure change in the water flow, generating shear force and vibration effect. When the pressure increases suddenly, a strong impact is generated. When the pressure drops suddenly, the slight negative pressure of the reverse flow of water helps to peel off the loose dirt. This can more effectively remove the bonding force between the hard scale layer and the pipe wall, accurately remove sewage, tar and other debris deposited in the bottom drain pipe of the water seal 1, avoid blockage that prevents the water seal 1 from draining normally, and ensure smooth gas transmission.

[0029] When water flows through the nozzle 9 and impacts the blockage in the drain pipe, the reaction force generated by the water impact causes the drain pipe 5 to sway. The collar 11 sways along with the drain pipe 5, and the guide frame 12 also moves accordingly. The guide rod 13, because one end is fixed to the external structure or the second connecting pipe 4 by the fixing block 15, will slide relative to the guide frame 12. During this process, the spring 16 will be compressed or stretched due to the relative displacement of the guide frame 12 and the limiting block 14. The elastic force generated will act in the opposite direction on the guide frame 12 and the limiting block 14, offsetting part of the impact force, thereby effectively buffering the impact on the drain pipe 5. At the same time, the sliding trajectory of the guide rod 13 within the guide frame 12 is strictly limited, and it can only move along the axial direction of the guide rod 13, preventing it from swinging significantly in other irregular directions. This effectively avoids violent shaking of the drain pipe 5 due to excessive impact force, ensuring that the unblocking operation is always stable.

[0030] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
