[0027] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted.

[0028] As Figure 1 and Figure 2As shown, the embodiment of the utility model discloses a kind of feeding port docking device, the docking device is connected between supply pipeline 200 and heating pipeline 100 and provides sealing for both. The docking device includes: main part 10, third flange 30, first wear ring 21, second wear ring 22 etc.

[0029] Main part 10 includes: first flange 11, second flange 12, barrel 13 and elastic component. First flange 11 is arranged with interval with second flange 12, and the opposite side of first flange 11 and second flange 12 is formed with bushing 17, barrel 13 is between first flange 11 and second flange 12, barrel 13 is made of elastic, flexible material, and the cylinder wall of barrel 13 is configured as wave structure, which makes barrel 13 can contract when subjected to axial force, and the end of barrel 13 is sleeved on the bushing 17 of first flange 11 and second flange 12 respectively, and the end of barrel 13 and bushing 17 are fixed by throat clamp 18.

[0030] Elastic component includes a plurality of cylindrical springs 14, which are between first flange 11 and second flange 12 and are uniformly distributed in the circumferential direction, the edge of first flange 11 and second flange 12 is processed with a plurality of ear plates 16 arranged in the circumferential direction, each cylindrical spring 14 is between the ear plate 16 of first flange 11 and second flange 12, and each cylindrical spring 14 is provided with a guide rod 15, one end of the guide rod 15 is screwed into the ear plate 16 of first flange 11 to be fixed with first flange 11, and the other end of the guide rod 15 passes through the ear plate 16 of second flange 12, so that under the guidance of guide rod 15, first flange 11 and second flange 12 can be axially close or away by overcoming the elastic force of cylindrical spring 14.

[0031] The end of supply pipeline 200 is formed with fourth flange 40, which is docked with third flange 30 of main part 10 and fixed by fastener.

[0032] A third flange 30 is formed at the feed port of the heating pipe 100, and the first flange 11 of the main body part 10 is opposite to the third flange 30 of the heating pipe 100. The first wear ring 21 and the second wear ring 22 are made of wear-resistant material, for example, graphite-based material, the first wear ring 21 is fixed on the disc surface of the first flange 11 and protrudes from the disc surface of the first flange 11, and the second wear ring 22 is fixed on the disc surface of the third flange 30 and protrudes from the disc surface of the third flange 30. The relative axial positions of the heating pipe 100 and the supply pipe 200 are set so that the first wear ring 21 on the first flange 11 is pressed against the second wear ring 22 on the third flange 30, and each cylindrical spring 14 has a certain compression amount.
