Detailed description of the invention
As shown in the figure, a kind of cylindrical shape turns round the anchor structure of hot equipment high-temperature hot conversion zone, adopts " V " shape metal anchorage 1, " Y " shape metal anchorage 2 and thrust beam 4 associating anchoring;
The set-up mode of described " V " shape metal anchorage 1 and " Y " shape metal anchorage 2 is: adopt " V " shape metal anchorage 1 and " Y " shape metal anchorage 2 to be crisscross arranged and carry out anchoring, anchor force is dispensed on " V " shape metal anchorage 1 height top, on joint three differing heights of " Y " shape metal anchorage 2 height top and " Y " shape metal anchorage 2 upper-lower section, " V " shape metal anchorage 1 and " Y " shape metal anchorage 2 top are opened and mutual in the plane at right angle setting, the extension 3 that described " Y " shape metal anchorage 2 joint has certain length is again in a certain angle in addition opening in the plane, thus the anchoring formed in three height and three planes,
The length direction that described thrust beam 4 turns round hot equipment along cylindrical shape is arranged, and is anchored on equipment inner wall by high-temperature metal anchoring piece by some unconnected nonmetal thrust bricks 5 each other.
The plane that described extension 3 is formed perpendicular to " Y " shape metal anchorage 2, thus form an anchoring plane.
Height on the height on above-mentioned three height highly referring to " V " shape metal anchorage 1 top, " Y " shape metal anchorage 2 top and " Y " shape metal anchorage 2 residing for extension 3, described three planes refer to the plane that on the plane on " V " shape metal anchorage 1 top, the plane on " Y " shape metal anchorage 2 top and " Y " shape metal anchorage 2, extension 3 is formed.
The quantity of described thrust beam 4 is arranged according to the diameter of stove, is generally 3-4 bar, and is uniformly distributed along the inwall of hot equipment.
The top of " V " of the present invention shape metal anchorage 1 and " Y " shape metal anchorage 2 for having the extension extended to " V " shape or " Y " shape both sides, thus forms stable anchoring plane.When arranging anchor point, by staggered to " V " shape metal anchorage 1 and " Y " shape metal anchorage 2, and the setting direction of adjacent " V " shape metal anchorage 1 and " Y " shape metal anchorage 2 is perpendicular.
The preferred arrangement mode of one of " Y " shape metal anchorage 2 is: along nearest two " Y " shape metal anchorages 2 of the hot equipment circumferential distance of revolution extension 3 towards relatively.
By above setting, after installing kiln lining, the anchor force effect that kiln lining is subject to three height and three planes comes off to prevent it: three height are followed successively by by the export-oriented kiln lining of kiln lining: the height residing for the extension 3 in the middle part of " Y " shape top of " Y " shape metal anchorage 2, " V " shape top of " V " shape metal anchorage 1 and " Y " shape of " Y " shape metal anchorage 2; Three planes are the planes corresponding to above-mentioned three height;
Meanwhile, due to the existence of thrust beam 4, limit kiln lining due to the sliding transfer that centrifugal force causes it to produce in stove rotation process, thus further enhancing the bond strength of kiln lining.
