[0029] A gas pipeline docking device according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0030] Referring to Figure 1 and Figure 2 , a gas pipeline docking device according to an embodiment of the present utility model includes a pipeline assembly, a sealing assembly, and a pressing assembly.

[0031] Among them, the pipeline assembly includes a connecting frame 100, an upper connecting pipe 110, and a lower connecting pipe 120. The connecting frame 100 is arranged on the outer wall of the furnace, the upper connecting pipe 110 is connected to the connecting frame 100, and the upper connecting pipe 110 and the lower connecting pipe 120 are docked up and down.

[0032] In some embodiments of the present utility model, a shock absorption assembly is further included. The shock absorption assembly includes a spring shock absorber 230, and the spring shock absorber 230 connects the upper connecting pipe 110 and the adapter ring 130.

[0033] Therefore, during the descent of the furnace, the upper connecting pipe 110 descends synchronously with the furnace. The adapter ring 130 is in direct contact with the end face of the lower connecting pipe 120. The spring damper 230 can suppress the impact generated by the contact between the adapter ring 130 and the lower connecting pipe 120, greatly reducing the damage of the upper connecting pipe 110 and the lower connecting pipe 120.

[0034] In some embodiments of the present invention, the upper connecting pipe 110 is provided with a connecting ring 240. The adapter ring 130 has an annular portion 250. The spring damper 230 connects the connecting ring 240 and the annular portion 250. A plurality of spring dampers 230 are provided, and the plurality of spring dampers 230 are arranged along the outer circumference of the connecting ring 240.

[0035] Therefore, by using a plurality of spring dampers 230 distributed outside the upper connecting pipe 110, when the upper connecting pipe 110 and the lower connecting pipe 120 are butted, the spring dampers 230 can evenly absorb the vibration generated by the butt joint.

[0036] In some embodiments of the present invention, the connecting frame 100 has a connecting plate 260. The connecting plate 260 is provided with a U-shaped groove 270. The U-shaped groove 270 accommodates the upper connecting pipe 110. The connecting plate 260 and the connecting ring 240 are connected by bolts 280.

[0037] Therefore, the upper connecting pipe 110 can be placed in the U-shaped groove 270, and the connecting plate 260 and the connecting ring 240 are locked by bolts 280. Thus, the upper connecting pipe 110 and the connecting frame 100 are connected and fixed, making the installation of the upper connecting pipe 110 convenient.

[0038] Wherein, a sealing assembly is arranged between the upper connecting pipe 110 and the lower connecting pipe 120, including an adapter ring 130, a first sealing ring 140 and a second sealing ring 150. The adapter ring 130 is slidably arranged up and down in the upper connecting pipe 110. The first sealing ring 140 is sleeved on the radial outer surface of the adapter ring 130. The adapter ring 130 is hermetically connected to the inside of the upper connecting pipe 110 through the first sealing ring 140. The second sealing ring 150 is arranged on the upper end face of the lower connecting pipe 120. The adapter ring 130 is hermetically connected to the lower connecting pipe 120 through the second sealing ring 150.

[0039] Wherein, the pressing assembly includes a first spring 160. The first spring 160 connects the upper connecting pipe 110 and the adapter ring 130, and the first spring 160 is sleeved on the upper connecting pipe 110.

[0040] In some embodiments of the present invention, the adapter ring 130 has a pipe portion 170 located inside the upper connecting pipe 110. A first annular groove 180 is arranged on the radial outer surface of the pipe portion 170. The first annular groove 180 accommodates the first sealing ring 140.

[0041] Therefore, the first sealing ring 140 is positioned by using the first annular groove 180 to prevent the first sealing ring 140 from detaching from the adapter ring 130 during the up-and-down movement of the adapter ring 130 within the upper connecting pipe 110.

[0042] In some embodiments of the present utility model, a first flange portion 190 is provided on the end face of the lower connecting pipe 120. The first flange portion 190 is provided with a second annular groove 200, and the second annular groove 200 accommodates the second sealing ring 150.

[0043] The area of the end face of the lower connecting pipe 120 is increased by using the first flange portion 190, enabling the second annular groove 200 to be formed and the second sealing ring 150 to be positioned in the second annular groove 200.

[0044] In some embodiments of the present utility model, a centering cone 210 is provided at the upper end of the lower connecting pipe 120. The centering cone 210 tapers in the direction approaching the upper connecting pipe 110, and the centering cone 210 is accommodated inside the adapter ring 130.

[0045] Therefore, during the docking process of the descent of the upper connecting pipe 110, the centering cone 210 gradually enters the inside of the adapter ring 130. The centering cone 210 is used to coaxially dock the upper connecting pipe 110 and the lower connecting pipe 120, ensuring accurate docking of the pipelines.

[0046] In some embodiments of the present utility model, referring to Figure 3 , the centering cone 210 is provided with an air guide channel 220. The air guide channel 220 communicates the upper connecting pipe 110 and the lower connecting pipe 120. Therefore, the gas in the lower connecting pipe 120 can enter the upper connecting pipe 110 through the air guide channel 220.

[0047] Therefore, the present embodiment has the following effects:

[0048] 1. By providing the connecting frame 100, the upper connecting pipe 110, and the lower connecting pipe 120, the upper connecting pipe 110 is fixed to the outer wall of the furnace through the connecting frame 100, and the lower connecting pipe 120 is used to supply gas. During the descent of the furnace, the upper connecting pipe 110 descends synchronously with the furnace, and the upper connecting pipe 110 and the lower connecting pipe 120 can be docked up and down. The docking method is simple and convenient.

[0049] 2. The utility model ensures that there is no leakage problem at the butt joint of the upper connecting pipe 110 and the lower connecting pipe 120 and is also conducive to improving the pipeline butt joint efficiency by arranging an adapter ring 130, a first sealing ring 140 and a second sealing ring 150. The adapter ring 130 can slide up and down inside the upper connecting pipe 110. There is a gap at the mating part between the adapter ring 130 and the inside of the upper connecting pipe 110. By sleeving the first sealing ring 140 on the adapter ring 130, the mating part between the adapter ring 130 and the upper connecting pipe 110 is hermetically connected. Moreover, there is also a gap at the contact surface between the adapter ring 130 and the lower connecting pipe 120. The second sealing ring 150 can be used to hermetically connect the contact surface between the adapter ring 130 and the lower connecting pipe 120.

[0050] 3. The utility model arranges a first spring 160. When the upper connecting pipe 110 and the lower connecting pipe 120 are butted up and down, the adapter ring 130 moves upward, and the first spring 160 is compressed under pressure. The first spring 160 can provide a downward pressure on the adapter ring 130 to ensure that the contact part between the adapter ring 130 and the lower connecting pipe 120 fits tightly. There is no need to use bolts 280 to connect and fix the upper connecting pipe 110 and the lower connecting pipe 120, and the pipeline can be quickly butted and installed, improving the efficiency of pipeline disassembly and assembly.

[0051] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples" or "some examples", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.
