Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipes, and in particular relates to an exhaust pipe connection with a staggered corrugated arrangement structure. Background Art

[0002] In the prior art, the working environment of the exhaust pipe is harsh, with high temperature, high pressure and high frequency vibration. Therefore, the exhaust pipe usually adopts a bellows to absorb vibration and prevent local rupture caused by rigid connection between the exhaust pipes. However, when the bellows is installed, the space occupied will be much larger than the straight pipe exhaust pipe of the same displacement. Especially when the space is limited, how to save the space required for arranging the exhaust pipe while ensuring that the bellows can absorb vibration is a technical problem that needs to be solved urgently. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the utility model provides an exhaust pipe having a staggered corrugated arrangement structure to solve the technical problem of insufficient installation space for the exhaust pipe due to the installation of a bellows.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] An exhaust pipe with a staggered corrugated arrangement structure includes an exhaust pipe assembly and flange bases arranged at both ends of the exhaust pipe assembly. The exhaust pipe assembly includes a plurality of exhaust units. The exhaust unit includes an exhaust pipe and an air connection pipe body. The air connection pipe body is fixed on one of the flange bases. The air connection pipe bodies in two adjacent exhaust units are staggered.

[0006] The inner end of the exhaust pipe is connected to the inner end of the air connection pipe body. The exhaust pipe and the interior of the air connection pipe body form an exhaust cavity. The flange base is provided with an air delivery hole connected to the exhaust cavity.

[0007] Furthermore, the main body of the gas connection pipe comprises an outer sleeve and an inner conduit. The outer sleeve is a corrugated pipe, and the inner conduit is a gas transmission joint pipe. The corrugated pipe is sleeved on the periphery of the gas transmission joint pipe, and the two ends are welded and fixed to the gas transmission joint pipe.

[0008] Furthermore, the gas transmission joint pipe comprises an inner end joint pipe, a middle joint pipe and an outer end joint pipe which are connected in sequence.

[0009] Furthermore, the inner ends of the inner and outer joint tubes are respectively connected to the two ends of the middle joint tube, and the outer end of the outer joint tube is welded and fixed to the inner wall of the corresponding gas transmission hole.

[0010] Furthermore, the inner end of the exhaust pipe and the inner end section pipe are fixed by welding.

[0011] Furthermore, the exhaust pipe also includes a connector. The connector adopts a ring structure. The connector is sleeved on the end of the exhaust pipe connected to the inner end section pipe and is welded and fixed to the corrugated pipe outside the inner end section pipe.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model staggers the positions of the bellows in two adjacent exhaust units by staggering the two air connection pipe bodies on each flange base, thereby ensuring that the bellows absorb vibrations while reducing the space occupied by the arrangement of multiple bellows.

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 and 2 As shown, an exhaust pipe with a staggered corrugated arrangement structure includes an exhaust pipe assembly and a flange base 1 arranged at both ends of the exhaust pipe assembly. The exhaust pipe assembly includes two exhaust units 2. The exhaust unit 2 includes an exhaust pipe 3, a connector 4 and an air pipe body 5. The inner end of the exhaust pipe 3 is connected to the inner end of the air pipe body 5 and is fixed by welding through the connector 4. The interior of the exhaust pipe 3 and the air pipe body 5 constitute an exhaust cavity. The flange base 1 is provided with a gas transmission hole connected to the exhaust cavity.

[0020] like Figure 3 As shown, the air connection pipe body 5 includes an outer sleeve and an inner conduit. The outer sleeve is a bellows 5-1, and the inner conduit is a gas transmission joint pipe 5-2. The bellows 5-1 is sleeved on the outer periphery of the gas transmission joint pipe 5-2, and both ends are welded and fixed to the gas transmission joint pipe 5-2. By setting the bellows, the vibration of the exhaust pipe can be absorbed to a certain extent, and a small radial or axial displacement of the exhaust pipe can be achieved.

[0021] The gas transmission joint pipe 5-2 includes an inner end joint pipe 5-2-1, a middle joint pipe 5-2-2 and an outer end joint pipe 5-2-3 which are connected in sequence. The inner ends of the inner end joint pipe 5-2-1 and the outer end joint pipe 5-2-3 are respectively connected with the two ends of the middle joint pipe 5-2-2. The outer end of the inner end joint pipe 5-2-1 is welded and fixed to the inner end of the exhaust pipe 3. The outer end of the outer end joint pipe 5-2-3 is welded and fixed to the inner wall of the corresponding gas transmission through hole. Dividing the gas transmission joint pipe 5-2 into multiple sections can effectively avoid the gas transmission joint pipe 5-2 from being difficult to extend to the end of the bellows 5-1 due to the bellows 5-1 being too long.

[0022] In addition, the connecting piece 4 adopts a ring sleeve structure. After the exhaust pipe 3 and the inner end section pipe 5-2-1 are welded, the connecting piece 4 is sleeved on the end portion where the exhaust pipe 3 and the inner end section pipe 5-2-1 are connected, and is welded and fixed to the corrugated pipe of the outer ring of the inner end section pipe 5-2-1.

[0023] In this embodiment, two exhaust units 2 are staggered. Specifically, the bellows 5-1 in one exhaust unit 2 is arranged side by side with the exhaust pipe 3 in another exhaust unit 2. The staggered arrangement saves space when multiple exhaust units 2 are installed.

[0024] In this embodiment, in the two exhaust units 2, the outer end of the exhaust pipe 3 is welded and fixed to the inner wall of the gas delivery hole on the corresponding flange base 1, and the outer end of the bellows 5-1 is welded and fixed to the inner wall of the gas delivery hole on the other flange base 1.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
