Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ceramic production, in particular to a device for preventing smoke leakage. Background Art
[0002] At present, with the changes in the market, the output of ceramic factories has declined in recent years, and some kilns have stopped production, but some kilns are still in normal production. However, the existing flue gas valves have more or less leakage. The untreated kiln flue gas after leakage will flow back to the unproduced kiln along the existing flue gas pipeline, causing corrosion to the kiln. In view of this situation, a device to prevent flue gas leakage is designed and installed on the flue gas pipeline of the unproduced kiln to prevent the untreated flue gas from flowing back and affecting the kiln. This device has a certain application market. Summary of the invention
[0003] The utility model aims to provide a device for preventing smoke leakage which is installed on the smoke pipeline of an unproduced kiln to prevent the backflow of untreated smoke from affecting the kiln and facilitates the maintenance of the fan.
[0004] The device for preventing smoke leakage of the utility model is realized in this way, comprising a smoke damper door arranged on the front section smoke pipeline, a non-metallic expansion joint connected to the inlet end of the rear section smoke pipeline, a side flange connected to the outlet end of the front section smoke pipeline, and a partition located at the side flange and driven by a hanger to move up and down, wherein the inlet end of the non-metallic expansion joint is connected to a flange with a sealing gasket.
[0005] When the air duct is in normal use, the partition is lifted by the hanger, the side flange at the outlet end of the front section of the smoke pipe is connected to the flange of the non-metallic expansion joint with bolts, and the smoke damper door is opened. In this state, the smoke can circulate normally; when it is necessary to stop, first close the front smoke damper door, pull the non-metallic expansion joint away from the outlet end of the front section of the smoke pipe, and then put down the partition, and firmly connect it to the side flange at the outlet end of the front section of the smoke pipe. At this time, the smoke will no longer leak, which plays a blocking role. Since the outlet end of the front section of the smoke pipe is closed by the partition, the smoke cannot leak from the front section of the smoke pipe.
[0006] Preferably, a circular ring is fixedly connected to the inlet end of the rear flue gas pipeline, a non-metallic expansion joint is fixedly connected to the circular ring, and a plurality of screws are fixedly connected to the back of the flange along the front end of the non-metallic expansion joint. After the screw passes through the circular ring, a nut is screwed on, and a spring is sleeved on the screw between the circular ring and the flange. When in use, the length between the circular ring and the flange is adjusted by the nut, thereby controlling the flange to lean against the side flange or to stay away from the side flange. The use of screws, nuts and springs facilitates the adjustment of the position of the flange.
[0007] Compared with the prior art, the utility model has the advantages of being installed on the smoke pipeline of an unproduced kiln, preventing the backflow of untreated smoke from affecting the kiln and facilitating the maintenance of the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The device for preventing smoke leakage of the utility model is now described in further detail with reference to the accompanying drawings and embodiments:
[0012] like Figure 1-2 As shown, the device for preventing smoke leakage of the utility model is implemented as follows, including a smoke damper door 2 arranged on a front smoke pipeline 1, a non-metallic expansion joint 4 connected to the inlet end of a rear smoke pipeline 3, a side flange 5 connected to the outlet end of the front smoke pipeline 1, and a partition 7 located at the side flange 5 and driven by a hanger 6 to move up and down. The inlet end of the non-metallic expansion joint 4 is connected to a flange 9 with a sealing gasket 8.
[0013] Preferably, a circular ring 10 is fixedly connected to the inlet end of the rear-stage flue gas pipeline 3, and the non-metallic expansion joint 4 is fixedly connected to the circular ring 10. A number of screws 11 are fixedly connected to the back side of the flange 9 along the front end of the non-metallic expansion joint 4. After the screws 11 pass through the circular ring 10, nuts 12 are screwed on them. A spring 13 is sleeved on the screws 11 between the circular ring 10 and the flange 9.
[0014] When in use, the length between the ring and the flange is adjusted by the nut, thereby controlling the flange to be close to the side flange or away from the side flange. The screw, nut and spring are used to facilitate the adjustment of the flange position.
[0015] When the air duct is used normally, the partition 7 is lifted by the hanger 6, and the length between the ring 10 and the flange 9 is adjusted by the nut 12, so as to control the flange 9 to lean against the side flange 5, and the side flange 5 at the outlet end of the front section of the flue gas pipeline 1 is bolted to the flange 9 of the non-metallic expansion joint 4, and the flue gas damper door 2 is opened. In this state, the flue gas can flow normally;
[0016] When it is necessary to stop, first close the baffle door 2 on the front section of the flue gas pipeline 1, adjust the length between the ring 10 and the flange 9 by the nut 12, and then control the flange 9 to be away from the side flange 5 of the front section of the flue gas pipeline 1, pull the non-metallic expansion joint away from the outlet end of the front section of the flue gas pipeline, lower the partition 7 by the hanger 6, and firmly connect it to the side flange 5 at the outlet end of the front section of the flue gas pipeline 1 by bolts. At this time, the flue gas will no longer leak, and a blocking effect will be achieved.
