Description

Technical Field

[0001] The utility model relates to the technical field of coke oven smoke treatment, in particular to a joint connection structure of a coke oven smoke exhaust port. Background Art

[0002] Coke oven, a furnace usually made of refractory bricks and refractory blocks, used to refractory coal to produce coke. The kiln that uses coal to make coke is the main thermal equipment for coking.

[0003] The gas exhaust pipe is an important device of the small coke oven. It is the only channel for the coke oven to discharge the raw gas and the only outlet for the reactor to release the pressure. In the prior art, the gas exhaust port is connected to the chemical product recovery device, which is higher than the outlet of the coke oven reactor. Therefore, the two are connected by a metal winding pipe. However, the metal winding pipe will fall down during long-term use, and the diameter of the pipe will become smaller at the bend, which will cause a large amount of coal tar to gather and block the entire pipeline.

[0004] Blockage of the smoke exhaust pipe can easily cause the raw gas to break through the graphite sealing ring between the reactor and the reactor cover, causing raw gas leakage, thereby polluting the environment. In severe cases, it may cause gas poisoning to employees on duty and increase the pressure in the reactor, leading to explosion. Utility Model Content

[0026] A connecting strip 504 is fixedly connected to one end of the connecting tube 502 away from the fixed tube 4, and a fixing column 505 is fixedly connected to the outer surface of the connecting strip 504 near the middle of the side away from the fixed tube 4. A movable groove 506 is provided on the outer surface of one end of the fixing column 505, and a movable rod 507 and a spring 508 are arranged inside the movable groove 506. When the connecting tube 502 enters the interior of the internal threaded tube 501 and is connected thereto, the connecting strip 504 drives the fixing column 505 to move toward the interior of the curved tube 2 along with the connecting tube 502. When the movable rod 507 conflicts with the curved tube 2, the movable rod 507 squeezes the spring 508 under the action of the curved tube 2. One end of the spring 508 is fixedly connected to the movable groove 506, and the other end is fixedly connected to the movable rod 507.

[0027] The movable rod 507 is movably connected to the movable groove 506, and one end of the movable rod 507 passes through the outside of the movable groove 506, one end of the movable rod 507 is hinged with a movable plate 1 509 near the surrounding position, and a movable plate 2 510 is hinged on the outer surface of the fixed column 505 at a position corresponding to the movable plate 1 509, and a support plate 511 is arranged between the movable plate 1 509 and the movable plate 2 510, and the movable plate 2 510 is squeezed to push the support plate 511 in the direction away from the movable rod 507, and the support plate 511 contacts the inner surface of the bent pipe 2, thereby supporting the bent pipe 2, and the support plate 511 is hinged to the movable plate 1 509 and the movable plate 2 510.

[0028] Embodiment three:

[0029] like Figure 3 and Figure 4 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 lies in that a connecting ring 1 7 is fixedly connected to a position near one end of the outer surface of the connecting pipe 502, and a connecting ring 2 8 is fixedly connected to the outer surface of the fixed pipe 4, a clamping ring 9 is fixedly connected to the side of the outer surface of the connecting ring 1 7 near the connecting ring 2 8, and a clamping groove 10 is provided on the outer surface of the connecting ring 2 8 at a position corresponding to the clamping ring 9. When the connecting pipe 502 enters the interior of the internal threaded pipe 501 and is connected thereto, the clamping ring 9 enters the interior of the clamping groove 10, and a plurality of groups of sealing rings 11 are fixedly connected to the interior of the clamping groove 10, and a sealing groove 12 matching the sealing ring 11 is provided on the outer surface of the clamping ring 9.

[0030] The working process and principle of the utility model are as follows:

[0031] Step 1: When connecting the elbow pipe 2 to the fixed pipe 4, rotate the connecting ring to rotate the connecting pipe 502 toward the internal threaded pipe 501 and enter the internal threaded pipe 501 until the connecting pipe 502 cannot move, and then inject sealant at the connection between the connecting pipe 502 and the fixed pipe 4 to ensure the sealing of the pipeline connection;

[0032] Step 2: When the connecting pipe 502 enters the inner threaded pipe 501 and is connected thereto, the connecting strip 504 drives the fixing column 505 to move along with the connecting pipe 502 toward the inner side of the curved pipe 2. When the movable rod 507 contacts the curved pipe 2, the movable rod 507 compresses the spring 508 under the action of the curved pipe 2. At this time, the movable plate 2 510 is squeezed to push the supporting plate 511 away from the movable rod 507. The supporting plate 511 contacts the inner surface of the curved pipe 2, thereby supporting the curved pipe 2 to prevent the curved pipe 2 from falling during the smoke exhaust process, which results in the pipe diameter at the bend becoming smaller and a large amount of coal tar accumulating to block the entire smoke exhaust pipe 1.

[0033] Step 3: During the above process, the clamping ring 9 enters the interior of the clamping groove 10, and the sealing ring 11 enters the interior of the sealing groove 12 and fits in, further strengthening the sealing of the entire smoke exhaust pipe 1 to prevent smoke from being directly discharged and polluting the air.
