Description

Technical Field

[0001] The utility model relates to the field of waste gas pipelines, in particular to a sewage and waste gas collecting pipeline. Background Art

[0002] There are many waste gases in the wastewater generated by paper mills. Odors such as hydrogen sulfide in these waste gases will spread outward. In order to prevent these waste gases from spreading outward and polluting the environment, it is necessary to use a gas collecting hood to absorb and collect the waste gases, and then transport them along the pipeline to the waste gas treatment system for treatment. The FRP pipes for transporting waste gases are mainly fixed by end-to-end splicing. The seal is not tight when splicing, and the splicing socket connection of the FRP pipe is easily loosened when it is disturbed and shaken by the internal waste gas airflow, causing waste gas leakage and affecting the surrounding environment. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a sewage and waste gas collecting pipeline.

[0004] The utility model is realized through the following technical solutions:

[0005] A sewage and waste gas collection pipeline comprises a glass fiber reinforced plastic pipeline and a socket at the front end thereof. The inner side of the socket is provided with a plurality of annular sealing grooves, and each sealing groove is provided with an inflatable telescopic sealing component.

[0006] Further optionally, the inflatable telescopic sealing assembly includes a supporting frame arranged on the inner wall of the sealing groove, an inflatable annular ring is arranged on the inner side of the supporting frame, and the inflatable annular ring is bound and connected to the supporting frame through a plurality of rubber rings.

[0007] Further optionally, an inflatable air nozzle is provided on the inflatable annular ring, and the air nozzle extends outward through a through hole provided on the sealing groove.

[0008] Further optionally, the inflatable annular ring is entirely located within the sealing groove when not inflated.

[0009] Further optionally, the supporting frame is arranged by a semi-elliptical elastic metal grid.

[0010] Compared with the existing technology, the beneficial effect of the utility model is as follows: the utility model can realize the sealed connection of the socket of the FRP pipe by arranging multiple sealing grooves in the socket of the FRP pipe through which the exhaust gas passes, and arranging an inflatable telescopic sealing component in the sealing groove, thereby preventing the exhaust gas leakage in the FRP pipe. At the same time, the inflatable telescopic sealing component can also buffer the shaking caused by the exhaust gas disturbance, avoid the loosening of the connection between two adjacent FRP pipes, and ensure the sealing of the FRP pipe connection.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0017] like Figure 1 As shown, a sewage and waste gas collection pipeline includes a glass fiber reinforced plastic pipeline 1 and a socket 2 at the front end thereof, a plurality of annular sealing grooves 3 are arranged on the inner side of the socket 2, and an inflatable telescopic sealing component 4 is arranged in each sealing groove 3.

[0018] like Figure 3 , 4 As shown, the inflatable telescopic sealing component 4 includes a supporting skeleton 5 arranged on the inner wall of the sealing groove 3, and an inflatable annular ring 7 is arranged on the inner side of the supporting skeleton 5. The inflatable annular ring 7 is bound and connected to the supporting skeleton 5 through a plurality of rubber rings 6. The inflatable annular ring 7 is fixed by the supporting skeleton 5 and its outer rubber ring 6 to prevent the inflatable annular ring 7 from detaching from the sealing groove 3, thereby ensuring that the inflatable annular ring 7 is tightly fitted and sealed with the FRP pipe 1 after inflation, and the inflatable annular ring 7 has better supporting stability for the FRP pipe 1.

[0019] like Figure 2 As shown, an inflatable air nozzle 8 is provided on the inflatable annular ring 7 , and the air nozzle 8 extends outward through a through hole 301 provided on the sealing groove 3 , and the inflatable seal is achieved through the air nozzle 8 .

[0020] like Figure 2 As shown, when the inflatable annular ring 7 is not inflated, it is completely inside the sealing groove 3. When the FRP pipe is installed and plugged in at the end, its plug-in end will not interfere with the inflatable telescopic sealing component 4 in the sealing groove 3, avoiding the risk of wear and tear due to installation.

[0021] The supporting frame 5 is provided with a semi-elliptical elastic metal grid frame, and is provided with spring steel so as to have better toughness.

[0022] The implementation principle of a sewage and waste gas collection pipeline in the embodiment of the present application is:

[0023] A multi-channel inflatable telescopic sealing component 4 is arranged in the socket 2 at the head and tail interface of the FRP pipe 1, and the inflatable annular ring 7 of the inflatable telescopic sealing component 4 is inflated through the air nozzle 8 to expand it. The inflated annular ring 7 fills the entire sealing groove 3 and fits tightly with the outer wall of the FRP pipe 1, thereby achieving a sealed connection of the socket 2 of the FRP pipe 1, thereby preventing the exhaust gas in the FRP pipe 1 from leaking;

[0024] The inflatable annular ring 7 is supported by a supporting frame 5 arranged in the sealing groove 3 to prevent the inflatable annular ring 7 from detaching from the sealing groove 3, thereby ensuring the stability of its position. In addition, the inflatable telescopic sealing assembly 4 in the multi-channel sealing groove 3 can also buffer the shaking caused by the exhaust gas disturbance, thereby preventing the connection between two adjacent FRP pipes 1 from loosening, thereby ensuring the sealing of the connection of the FRP pipe 1.
