The water seal seat is an annular structure characterized by a U-shaped groove. The upper end of the outer ring of the U-shaped groove has a water inlet pipe, which can be filled with liquids such as water or oil to achieve the purpose of water sealing the flue gas pipe. This design effectively solves the problem of gas leakage, prevents the leakage of harmful gases, and can also recover these gases as industrial raw materials, thus solving environmental pollution problems and realizing resource recycling.

[0003] After a period of use, the water seal seat will age and wear, requiring timely replacement. However, most existing water seal seats are installed by welding or bolting, which makes disassembly and assembly inconvenient when replacement is needed, affecting the subsequent use of the coke oven and needs to be improved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a flue gas water seal seat that enables convenient disassembly and replacement of the water seal seat, thereby solving the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flue gas water seal seat, comprising a furnace ring disposed on the flue gas guide hole of a coke oven, a sealing cover disposed on the furnace ring, a water seal seat disposed on the outer top of the coke oven around the flue gas guide hole, and a liftable flue gas pipe inserted into a U-shaped groove containing water seal liquid on the water seal seat. The bottom of the water seal seat is fixed with a plurality of mounting blocks evenly distributed in a circular pattern. A first arc-shaped groove is formed on the outer side of the mounting block, and an mounting groove is formed on the outer top of the coke oven corresponding to the mounting block. A second arc-shaped groove is formed on the side of the mounting groove away from the flue gas guide hole. A motor is built into the coke oven below the second arc-shaped groove. The output shaft of the motor extends upward into the second arc-shaped groove and is fixedly connected to a rotating plate. The mounting block is inserted into the corresponding mounting groove. The first arc-shaped groove communicates with the corresponding second arc-shaped groove and forms a rotating cavity of the corresponding rotating plate. The rotating plate can rotate into the first arc-shaped groove to engage with the corresponding mounting block.

[0006] Preferably, the mounting block is adapted to the corresponding mounting slot.

[0007] Preferably, both the first arc-shaped groove and the second arc-shaped groove are adapted to the rotation trajectory of the rotating plate.

[0008] Preferably, a sealing gasket is fixed at the bottom of the water seal seat.

[0009] Preferably, an elastic rubber pad is fixed to the bottom of the rotating plate.

[0010] Preferably, the smoke guide pipe includes an upper fixed section, a lower lifting section, and a telescopic corrugated pipe fixedly connected between the fixed section and the lifting section. Several hydraulic cylinders are fixedly mounted on the bottom of the fixed section around the telescopic corrugated pipe, and the piston rods of the hydraulic cylinders face downward and are fixedly connected to the top of the lifting section.

[0011] Preferably, a water injection pipe is fixedly connected to the upper part of one side of the water seal seat, and a water supply pipe is fixedly provided on the top of the coke oven on one side of the water injection pipe.

[0013] The beneficial effects of this utility model are as follows: When the water seal seat needs to be replaced due to aging and wear after a period of use in a coke oven, it can be done while the machine is stopped. First, raise the flue pipe to a suitable height and disconnect the connection between the water seal seat and the corresponding water supply pipe. Then, run the motor to rotate the rotating plate 180 degrees, moving it from the first arc groove to the second arc groove. This releases the locking and fixing of the mounting block. Then, pull out the mounting block to remove the entire water seal seat. Afterward, take a new water seal seat, align its mounting block with the corresponding mounting groove, and insert it into place, connecting the first arc groove with the corresponding second arc groove. Then, run the motor to rotate the corresponding rotating plate 180 degrees, moving it from the second arc groove to the first arc groove, locking and fixing the mounting block.

[0024] like Figures 1 to 8 As shown, a flue gas water seal seat includes a furnace ring 3 on the flue gas guide hole 2 of a coke oven 1, a sealing cover 4 on the furnace ring 3, a water seal seat 5 on the outer top of the coke oven 1 around the flue gas guide hole 3, and a liftable flue gas pipe 7 inserted into a U-shaped groove 6 containing water seal liquid on the water seal seat 5. Several mounting blocks 8 are fixedly provided at circumferential intervals at the bottom of the water seal seat 5, and a first arc-shaped groove 9 is formed on the outer side of each mounting block 8. An mounting groove 10 is formed on the outer top of the coke oven 1 corresponding to the mounting block 8. A second arc-shaped groove 11 is formed on the side of the mounting groove 10 away from the flue gas guide hole 2. A motor 12 is built into the coke oven 1 below the second arc-shaped groove 11, and the output shaft of the motor 12 extends upward into the second arc-shaped groove 11 and is fixedly connected to a rotating plate 13. The mounting block 8 is inserted into the corresponding mounting slot 10. The first arc-shaped slot 9 is connected to the corresponding second arc-shaped slot 11 and forms a rotating cavity of the corresponding rotating plate 13. The rotating plate 13 can be rotated into the first arc-shaped slot 9 to engage with the corresponding mounting block 8.

[0025] When the water seal seat 5 needs to be replaced due to aging and wear after the coke oven 1 has been used for a period of time, it can be done in the shutdown state by first raising the flue pipe 7 to a suitable height and disconnecting the connection between the water seal seat 5 and the corresponding water supply pipe 21. Then, the motor 12 is run to drive the rotating plate 13 to rotate 180 degrees, moving the rotating plate 13 from the first arc groove 9 to the second arc groove 11, thereby releasing the locking and fixing of the mounting block 8. Then, the mounting block 8 can be pulled out to remove the entire water seal seat 5. After that, a new water seal seat 5 is taken, and the mounting block 8 on it is aligned with the corresponding mounting groove 10 and inserted into place, so that the first arc groove 9 is connected to the corresponding second arc groove 11. Then, the motor 12 is run to drive the corresponding rotating plate 13 to rotate 180 degrees, moving the rotating plate 13 from the second arc groove 11 to the first arc groove 9, locking and fixing the mounting block 8. This completes the installation and fixing of the entire water seal seat 5, and the fixing is more stable and reliable, without affecting subsequent use. Then, connect the water seal seat 5 to the water supply pipe 21, lower the flue pipe 7 back to the qualified position, and inject an appropriate amount of water seal liquid into the U-shaped groove 6 of the water seal seat 5 through the water supply pipe 21. Then, it can continue to be used. This allows for flexible and convenient disassembly and replacement of the entire water seal seat 5, making its overall use more flexible and convenient, more beneficial for subsequent coke oven production, and more practical. The coke oven 1, flue pipe 2, furnace ring 3, sealing cover 4, water seal seat 5, and flue pipe 7 can all use existing technology; their specific structures and working principles are also existing technologies and will not be detailed here.

[0026] In this embodiment, the mounting block 8 is adapted to the corresponding mounting groove 10 to ensure that the mounting block 8 is smoothly inserted into place. This facilitates the smooth positioning and installation of the water seal seat 5.

[0027] In this embodiment, the first arc groove 9 and the second arc groove 11 are both adapted to the rotation trajectory of the rotating plate 13 to ensure that the rotating plate 13 rotates smoothly and cooperates to achieve smooth positioning and fixing of the water seal seat 5.

[0028] In this embodiment, a sealing gasket 14 is fixedly provided at the bottom of the water seal seat 5 to ensure the sealing effect between the water seal seat 5 and the coke oven 1 after installation, so as not to affect subsequent operation.

[0029] In this embodiment, an elastic rubber pad 15 is fixed at the bottom of the rotating plate 13, which can produce elastic deformation to ensure that the rotating plate 13 rotates smoothly in the first arc groove 9 and the second arc groove 11. When the rotating plate 13 rotates into the first arc groove 9 to achieve the snap-fit ​​and fixation of the mounting block 8, the elastic deformation force of the elastic rubber pad 15 can be used to further press the mounting block 8, which can better ensure the stability and reliability of the water seal seat 5 installation and fixation.

[0030] In this embodiment, the smoke guide pipe 7 includes an upper fixed section 16, a lower lifting section 17, and a telescopic corrugated pipe 18 fixedly connected between the fixed section 16 and the lifting section 17. Several hydraulic cylinders 19 are fixedly mounted on the bottom of the fixed section 16 around the telescopic corrugated pipe 18. The piston rod of the hydraulic cylinder 19 faces downward and is fixedly connected to the top of the lifting section 17, so that in actual use, the lifting section 17 of the smoke guide pipe 7 can be driven to rise and fall by the extension and retraction of the piston rod of the hydraulic cylinder 19 in conjunction with the telescopic corrugated pipe 18.

[0031] In this embodiment, a water injection pipe 20 is fixedly connected to the upper part of one side of the water seal seat 5. A water supply pipe 21 is fixedly installed on the top of the coke oven 1 on one side of the water injection pipe 20. A flexible hose 22 is fixedly connected to the end of the water supply pipe 21, and a connecting pipe 23 is fixedly connected to the end of the flexible hose 22. The connecting pipe 23 is connected to the water injection pipe 20 through a quick connector 24. In actual use, the water supply pipe 21 and the water injection pipe 20 can be quickly connected and disconnected through the cooperation of the flexible hose 22 and the quick connector 24, so as to ensure convenient disassembly and replacement of the entire water seal seat 5. A water seal liquid source is connected to the water supply pipe 21, so that in actual use, the corresponding water seal liquid can be added to the U-shaped groove 6 of the water seal seat 5 through the cooperation of the water supply pipe 21, flexible hose 22, connecting pipe 23 and water injection pipe 20 to achieve water seal operation.

[0032] In this embodiment, a solenoid valve 25 is provided on the connecting pipe 23, and an inverted L-shaped support rod 26 is fixedly connected to the top of the connecting pipe 23. The tail end of the horizontal part of the support rod 26 is located above the U-shaped groove 6 of the water seal seat 5, and a non-contact level gauge 27 is installed at the bottom of the tail end. A controller 28 is fixedly provided on the outer top of the coke oven 1.
