Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, a double-deck socket joint formula chimney, includes a plurality of sections chimney sections 1, chimney section 1 includes inner tube 2 and urceolus 3, the bottom of inner tube 2 is provided with socket 5, the top of inner tube 2 is provided with bellmouth 4, and inner tube 2 between two adjacent chimney sections 1 passes through bellmouth 4 and socket 5 plug-in connection, the junction of bellmouth 4 and socket 5 is provided with sealing washer 6, be connected through supporting component between inner tube 2 and the urceolus 3, supporting component includes the bearing support group 7 on a plurality of layers that set up from last to down on the outer wall of inner tube 2, supporting component still including set up on the inner wall of urceolus 3 and with bearing support group 7 complex bearing ear group 8.

According to the double-layer socket chimney, each section of the chimney section 1 is about 8-16 meters, the chimney section 1 is divided into the inner barrel 2 and the outer barrel 3, and the chimney is manufactured into a whole in a factory.
