Detailed Description
The specific technical solution of the present invention will be described with reference to the embodiments.
As shown in fig. 1 and 2, the indirect heating rotary kiln rolling ring supporting device comprises a plurality of first supporting mechanisms and a plurality of second supporting mechanisms which are uniformly arranged between the inner wall of a rolling ring 1 and the outer wall of a kiln body 2;
the first supporting mechanism comprises a first rolling ring backing plate 11 and a first kiln body backing plate 21, the first rolling ring backing plate 11 is fixed on the inner wall of the rolling ring 1, the first kiln body backing plate 21 is fixed on the outer wall of the kiln body 2, the first rolling ring backing plate 11 and the first kiln body backing plate 21 correspond to each other one by one, and each group of the first rolling ring backing plate 11 and the first kiln body backing plate 21 which are opposite to each other are mutually clung to form a group of supporting blocks;
the second supporting mechanism include that second rolls a ring backing plate 12 and second kiln body backing plate 22, second rolls a ring backing plate 12 and fixes on the inner wall that rolls ring 1, and second kiln body backing plate 22 fixes on the outer wall of the kiln body 2, and second rolls a ring backing plate 12 and second kiln body backing plate 22 one-to-one to be fixed with slider 13 on the second rolls a ring backing plate 12, second kiln body backing plate 22 on be equipped with corresponding spout 23, spout 23 along kiln body 2 surface vertically set up, slider 13 be located spout 23 in form the sliding pair.
As shown in fig. 3, two ends of the sliding chute 23 are respectively provided with a baffle 24, and the length of the sliding block 13 along the longitudinal direction of the kiln body 2 is shorter than that of the sliding chute 23.
When the kiln body 2 longitudinally deforms and stretches, the first support mechanism and the plurality of second support mechanisms can slide relatively, wherein the sliding block 13 slides in the sliding groove 23, and the sliding range is limited by the baffle 24.
