[0027] As a preferred scheme of the embodiment: the sealing mechanism 2 comprises a partition plate 201, a rotating shaft 202, a first through hole 203, a rotating plate 204, a spring 205, a worm wheel 206, a sliding groove 207, a second through hole 208 and a first sealing block 209, the inside of the partition plate 201 is provided with a plurality of first through holes 203, the middle position of the bottom of the partition plate 201 is provided with the rotating shaft 202, the bottom of the rotating shaft 202 is provided with the worm wheel 206, the outside of the rotating shaft 202 is provided with the rotating plate 204, the inside of the rotating plate 204 is provided with two groups of second through holes 208, the two sides of the inside of the second through hole 208 are provided with the sliding groove 207, the inside of the sliding groove 207 is slidably provided with the first sealing block 209, and the two sides of the bottom of the first sealing block 209 are provided with the spring 205, so that the lower bridge pipe 10 can be sealed.

[0028] As a preferred scheme of the embodiment: one side of the worm 6 extends to the inside of the lower bridge pipe 10, the worm 6 and the worm wheel 206 are meshed with each other, and the worm wheel 206 is driven to rotate.

[0029] As a preferred scheme of the embodiment: the output end of the hydraulic rod 9 extends to the inside of the sleeve 13, and the piston 15 and the sleeve 13 are matched with each other, so that the sleeve 13 can be pulled.

[0030] One side of the connecting rod 3 close to the hydraulic rod 9 is fixedly connected with the hydraulic rod 9, the connecting rod 3 is provided with two groups, so that the sliding ring 20 moves along with the hydraulic rod 9.

[0031] The outer side of the annular brush 19 is in contact with the inner side of the fixed cup 11. The annular brush 19 is connected to the sliding ring 20 through the fixed rod to clean the inner side of the fixed cup 11.

[0032] The cross-section of the first sealing block 209 is trapezoidal. The first sealing block 209 and the first through hole 203 are adapted to each other so that the inclined side of the first sealing block 209 contacts the edge of the first through hole 203 and can move out from inside the first through hole 203.

[0033] As a preferred embodiment, an air collection pipe is provided at the bottom of the lower bridge pipe 10.

[0034] As a preferred embodiment, the number of first through holes 203 and second through holes 208 is the same, and the first through holes 203 and the second through holes 208 correspond one-to-one, which facilitates sealing of the first through holes 203.

[0035] Example 1, such as Figures 4-5 When the hydraulic rod 9 is opened, it drives the sliding ring 20 to slide up and down inside the annular seat 22 through the two sets of connecting rods 3. This causes the annular seat 22 to move the ventilation groove 21 inside the ammonia water, increasing or decreasing the gap between the ventilation groove 21 and the water level. This increases or decreases the ventilation area, which in turn decreases or increases the resistance when raw coal gas passes through. By controlling the depth of the ventilation groove 21 submerged in the liquid and the airflow, the pressure can be controlled.

[0036] Example 2, as Figures 4-5 As shown, when maintenance is required on the gas collecting pipe, the worm gear 6 is rotated, which drives the worm wheel 206 to rotate. The worm wheel 206 drives the rotating plate 204 to rotate through the rotating shaft 202, causing the rotating plate 204 to move the first sealing block 209. When the first sealing block 209 moves to the first through hole 203, the two sets of springs 205 push the first sealing block 209 upward inside the sliding groove 207, so that the first sealing block 209 seals the first through hole 203. At this time, a seal is formed between the partition plate 201 and the rotating plate 204, sealing the lower bridge pipe 10.

[0037] Working principle: in different time periods of coking, different pressure needs to be kept in the carbonization chamber of coke oven, at this time the hydraulic rod 9 can be opened to work, at this time the hydraulic rod 9 drives the sliding ring 20 to slide up and down in the inside of the annular seat 22 through two groups of connecting rods 3, so that the annular seat 22 drives the air passage 21 to move in the inside of ammonia water, so that the gap between the air passage 21 and the water level increases or decreases, so that the air passage area also increases or decreases, so that the resistance of the raw coal gas passing through decreases or increases, controlling the depth of the air passage 21 immersed in the liquid surface and the air flow, the pressure can be controlled, through the closing mechanism 2, the inside of the lower bridge pipe 10 can be sealed, when the gas collecting pipe is maintained, the leakage of the raw coal gas can be prevented, when the hydraulic rod 9 drives the piston 15 to move upwards, the sealing cone 16 is driven to move upwards through the sleeve 13, so that the sealing cone 16 and the first outlet 14 are separated from each other, at the same time, the second sealing block 12 is driven to move out of the inside of the second outlet 18 by the telescopic rod 17, so that the raw coal gas flows through the second outlet 18 and the first outlet 14.

[0038] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, and is not a limitation on the protection scope of the present application. Simple modifications or equivalent replacements of the technical solutions of the present application made by those skilled in the art do not deviate from the essence and scope of the technical solutions of the present application.
