Description

Technical Field

[0001] The invention relates to the technical field of sealed connection of folded pipes, in particular to a sealing structure and a VCM loading crane pipe to incinerator pipeline. Background Art

[0002] During the connection process of the VCM loading crane pipe, in order to achieve the extension of the pipeline, one end of the crane pipe is a folded pipe.

[0003] In the prior art, a sealed connection is usually used to connect the foldable tube and the rigid tube.

[0004] However, in actual use, the traditional sealing connection device lacks a buffer component, so when the folding tube is extended, the internal pressure decreases. When the folding tube is folded and stored, the tube becomes shorter and the internal pressure increases, causing the material in the tube to be squeezed, thereby causing the sealing connection to be compressed and deformed. With multiple folding and extension, the sealing connection position is continuously squeezed, causing the gap at the connection position to gradually increase, resulting in damage to the sealing. Summary of the Invention

The other end of the connecting end head 3 is sealed with the connecting pipe 1 through the ear seat 9. The sealed connection is achieved by providing the ear seat 9.

[0037] An inner lining tube 14 is provided at one end of the connecting end 3 close to the connecting pipe 1. The inner lining tube 14 is inserted into the stepped inner groove 5, and a sealing gasket 16 is fastened and pressed between the end of the inner lining tube 14 and the stepped inner groove 5. The sealing performance of the connection is further improved by providing the inner lining tube 14 and the sealing gasket 16.

[0038] A pair of inclined arc pieces 8 distributed in a circumferential array are provided on the inner wall of the buffer ring 2, and a first card groove 17 is formed between the inclined arc piece 8 and the inner wall of the connecting tube 1, and a pair of inner plug-in plates 12 distributed in a circumferential array are provided on the inner side of the connecting end 3, and the outer wall of the inner plug-in plate 12 is provided with an extrusion paddle 15 inclined outward, and the extrusion paddle 15 is rotatably engaged in the first card groove 17, one end of the inclined arc piece 8 is fixed on the inner wall of the buffer ring 2, and the other end of the inclined arc piece 8 is inclined toward the inner side of the buffer ring 2, the outer diameter of the inner plug-in plate 12 is smaller than the outer diameter of the inner liner tube 14, one end of the inner plug-in plate 12 is fixedly mounted on the inner liner tube 14, and the other end of the inner plug-in plate 12 is provided with an extrusion paddle 15 extending outward, and a circular second card groove 23 is formed between the extrusion paddle 15 and the outer wall of the inner plug-in plate 12, and the inclined arc piece 8 is engaged in the second card groove 23

[0039] By utilizing the rotational engagement of the extrusion paddle 15 and the inclined arc piece 8, staggered extrusion is formed to buffer the impact force along the flow direction of the connecting pipe 1, thereby achieving the purpose of maintaining the stability of the sealing device under repeated impacts of the internal pressure, improving the service life of the folded tube 4, and avoiding leakage.

[0040] A pair of side blocks 7 are provided on the arc outer wall of the connecting pipe 1, and an outer plug-in plate 10 plugged into the side blocks 7 is provided on one side of the connecting end 3. The outer plug-in plate and the side blocks 7 are plugged in together to facilitate the rotation adjustment of the extrusion paddle 15.

[0041] A VCM loading crane pipe to incinerator pipeline comprises the above-mentioned sealing structure.

[0042] Example 2:

[0043] On the basis of Example 1, in order to improve the position limitation of the rotation adjustment, the present application also has an inclined arc piece 8 that is a one-sixth circular arc piece, and the inner insert plate 12 is a one-sixth circular arc piece, and the side block 7 is slidably inserted with a pressure block 20 close to the side of the connecting end 3, and the outer insert plate 10 is provided with an inserting inner groove consisting of a vertical groove 11 and a rotating groove 13. The side block 7 is inserted into one side end of the rotating groove 13 along the vertical groove 11, and the side block 7 is squeezed and fixed to the other end of the rotating groove 13 through the rotation of the connecting end 3.

[0044] During the plug-in process, the side block 7 is plugged into the external plug-in board 10 along the vertical groove 11. At this time, the inclined arc piece 8 and the extrusion paddle 15 are staggered. As the side block 7 rotates on the rotation groove 13, the inclined arc piece 8 and the extrusion paddle 15 rotate and engage, and the ear seats 9 correspond to each other. The rotation angle is limited by the rotation groove 13 to achieve the purpose of precise adjustment.

[0045] Example 3:

[0046] On the basis of Example 2, in order to improve the stability after rotation adjustment and avoid falling off, the present application also has a spring 21 pressed between the pressure block 20 and the side block 7, a telescopic socket 18 is provided on the side block 7, and side plates 24 that slide and fit the outer wall of the side block 7 are provided at both ends of the pressure block 20. An insertion rod 19 is provided at one end of the pressure block 20, and the insertion rod 19 is slidably inserted in the telescopic socket 18. The spring 21 is sleeved on the insertion rod 19, and the two ends of the spring 21 are pressed between the pressure block 20 and the side block 7. The width of the pressure block 20 is equal to the width of the vertical groove 11, the length of the pressure block 20, the spring 21 and the length of the side block 7 are greater than the width of the rotating groove 13, and the length of the pressure block 20 and the side block 7 is less than the width of the rotating groove 13.

[0047] By utilizing the cooperation of the spring 21 and the insertion rod 19, the telescopic installation of the pressure block 20 is realized, so that when the side block 7 slides on the vertical groove 11, the spring 21 is squeezed through the vertical distribution with the rotating groove 13, so that the distance between the pressure block 20 and the side block 7 is reduced. The pressure block 20 and the side block 7 are pressed together in the rotating groove 13. Under the reset elastic force of the spring 21, the position of the side block 7 and the pressure block 20 is fixed, thereby avoiding the problem of self-rotation and falling off.
