Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for tamping coke ovens, and in particular to a purging device for the root of the riser pipe of a tamping coke oven. Background Technology

[0002] During the production process of a tamped coke oven, the raw coal gas contains carbonaceous components. Under high-temperature conditions, these carbonaceous components tend to gradually precipitate and deposit in areas such as the inner wall of the riser pipe root, forming graphite. Over time, the graphite accumulates and increases, narrowing the channel at the riser pipe root. Therefore, it is necessary to purge the riser pipe root of the tamped coke oven.

[0003] In the prior art, such as the announcement number CN215667827U, a graphite cleaning device for the root of the riser pipe is disclosed. This patent involves welding multiple air outlet pipes around the base of the riser pipe near the root of the coke oven, and blowing nitrogen gas through the air outlet pipes to clean the coal powder and graphite adhering to the root of the riser pipe.

[0004] However, in actual cleaning, since the end of the gas outlet pipe extends into the inside of the coking oven riser pipe, it is easily damaged or adhered due to the long-term high temperature environment and dust environment, requiring maintenance or cleaning. The gas outlet pipe that is fixedly welded to the side wall of the riser pipe in the above-mentioned patent is more difficult to maintain or clean.

[0005] In view of this, a purging device for the root of the coke oven riser pipe is proposed to solve the above problems. Utility Model Content

The inner wall of the rotating sleeve 303 is provided with a thread that matches the threaded groove on the surface of the mounting tube 2. Three handles 304 are fixedly connected around the surface of the rotating sleeve 303. The surface of the air supply pipe 4 is fixedly embedded in the center of the surface of the docking plate 301, and the surface of the air supply pipe 4 penetrates the interior of the docking plate 301.

[0022] Specifically, such as Figure 1 , 5 As shown in Figure 6: By means of the thread provided on the inner wall of the rotating sleeve 303 and the threaded groove provided on the surface of the mounting tube 2, the rotating sleeve 303 can be rotated and moved on the surface of the mounting tube 2 when the handle 304 is rotated.

[0023] In one embodiment, a side hole 401 is provided below the end of the gas supply pipe 4. The side hole 401 is inclined downward at 30°-45°. A bottom hole 402 is provided below the surface of the gas supply pipe 4 and near the side hole 401. The bottom hole 402 is vertically downward. Both the side hole 401 and the bottom hole 402 are located inside the tamping coke oven riser pipe 1.

[0024] Specifically, such as Figure 2 , 4As shown in Figure 6, nitrogen gas is discharged through the side hole 401 and bottom hole 402 at one end of the gas supply pipe 4 to purge and clean the rising pipe of the tamping coke oven. The side hole 401, which is set at an angle of 30°-45° downward, focuses on purging the graphite and tar adhering to the root side wall. The bottom hole 402, which is set vertically downward, can purge the debris deposited at the bottom of the root. The two work together to achieve all-round cleaning without dead angles.

[0025] In one embodiment, a plurality of mounting pipes 2 are circumferentially and equidistantly connected to the surface of the tamping coke oven riser pipe 1 and located above the base at the lower end of the tamping coke oven riser pipe 1.

[0026] Specifically, such as Figure 1-3 As shown: Multiple mounting pipes 2 can be adapted to surround the coke oven riser pipe 1 according to its diameter, so as to cover the circumferential trajectory above the root of the coke oven riser pipe 1.

[0027] In one embodiment, a first sealing gasket 6 is movably sleeved on the surface of the mounting tube 2, and one side of the first sealing gasket 6 is attached to one side of the connecting disc 201. A rotating sleeve 303 is threaded onto the surface of the mounting tube 2, and one end of the rotating sleeve 303 presses against the other side of the first sealing gasket 6.

[0028] Specifically, such as Figure 4 , 7 As shown in Figure 8, one end of the rotating sleeve 303 abuts against one side of the first sealing gasket 6 to achieve a compression seal.

[0029] In one embodiment, a second sealing gasket 7 is movably fitted inside the second annular groove 203. One side of the second sealing gasket 7 presses against one side of the docking plate 301. The second sealing gasket 7 is located inside the fixing ring 302 and is fitted onto the surface of the air supply pipe 4.

[0030] Specifically, such as Figure 3 , 8 As shown: one side of the second sealing gasket 7 presses against one side of the mating disc 301 to achieve a compression seal.

[0031] In one embodiment, the surfaces of the connecting plate 201 and the mating plate 301 are provided with a plurality of through holes, and the two opposite through holes are fastened together by fastening bolts 5.

[0032] Specifically, such as Figure 1-8 As shown: the fastening bolt 5 passes through the through hole of the connecting plate 201 and the mating plate 301 to fasten them, thereby completing the fastening between the connecting plate 201 and the mating plate 301.

[0033] Working principle: When using the purging device for the root of the coke oven riser pipe, the first sealing gasket 6 is first placed on the surface of the mounting pipe 2 and made to fit against one side of the connecting plate 201. The second sealing gasket 7 is placed inside the second annular groove 203. Then, the air supply pipe 4 is inserted into the mounting pipe 2 by holding the handle 304, and the rotating sleeve 303 is placed on the surface of the mounting pipe 2. Then, by rotating the handle 304, the rotating sleeve 303 rotates and moves at the part of the mounting pipe 2 with the threaded groove. At the same time, as the rotating sleeve 303 rotates and moves, it also drives the connecting plate 301 to move. Continue rotating until one end of the rotating sleeve 303 is tightly pressed against one side of the first sealing gasket 6 for a tight seal. At this time, the... One side of the receiving plate 301 will also be tightly sealed against the side of the second sealing gasket 7. Then, the fastening bolts 5 will be used to fasten the connecting plate 201 and the connecting plate 301 through the through holes on the surface of the connecting plate 201 and the connecting plate 301. After the installation is completed, one end of the gas supply pipe 4 will be connected to the external nitrogen supply pipe. Nitrogen will be discharged through the side hole 401 and the bottom hole 402 at one end of the gas supply pipe 4 to purge and clean the coke oven riser pipe. The side hole 401, which is inclined downward at 30°-45°, focuses on purging the graphite and tar adhering to the root side wall, while the bottom hole 402, which is vertically downward, can purge the debris deposited at the root bottom. The two work together to achieve all-round cleaning without dead angles.

[0034] With the above structure in place, the rotating sleeve 303 can be screwed and fastened to the surface of the mounting tube 2 by rotating the sleeve 303, and then the connecting plate 201 and the mating plate 301 can be tightened and fixed by fastening bolts 5. The double fixation prevents loosening. When replacement or cleaning is required, reverse the above operation to remove the rotating sleeve 303 and the docking plate 301 and pull out the air supply pipe 4. This method can remove the air supply pipe 4, making maintenance and cleaning more convenient.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
