After the external air pipe 600 conveys cooling air to the cavity 120, a part of the cooling air in the cavity 120 can blow to the L-shaped supporting member 200 through the vent holes 112, so that the L-shaped supporting plate 200 can be effectively cooled in the kiln burning process, and the problem that the strength of the L-shaped supporting plate 200 is reduced due to thermal deformation and cannot bear the big arch brick 4 is avoided.
As shown in fig. 3 and 5, in some embodiments of the present invention, a second through hole for the jackscrew 500 to pass through is provided on the steel frame 100, and a nut 132 matched with the jackscrew 500 is welded on the inner side wall of the H-beam 130 at a position corresponding to the second through hole; and a sealing gasket 133 is arranged on the outer side wall of the vertical section of the H-shaped steel 130 away from the L-shaped support 200 and corresponds to the second through hole. The tightening of the jackscrew 500 is adjustable by the nut 132 to control the distance of the backward expansion of the crown 4. In the baking kiln and the masonry process, besides the height of the main arch brick 4 is adjusted through the brace 3, the height of each ring brick can also be accurately adjusted through the jackscrew 500, so that the stability, firmness and safety of the whole main arch are ensured. The provision of the sealing gasket 133 prevents the cooling air supplied into the cavity 120 from flowing out of the second through hole to the outside and failing to cool the L-shaped support 200. It should be understood that the welding is only one preferable way to connect the nut 132 to the inner side wall of the H-beam 130 at a position corresponding to the second through hole, and the specific installation manner is not limited, and other manners such as adhesion may be used instead according to actual needs.
As shown in fig. 3 and 5, in some embodiments of the present invention, a sleeve 134 is sleeved outside the jackscrew 500, one end of the sleeve 134 abuts against the nut 132, and the other end of the sleeve 134 abuts against the rear inner sidewall of the H-beam 130. The sleeve 134 is matched with the nut 132, so that the jackscrew 500 can be screwed on the steel frame 100 more stably, and the sleeve 134 can avoid that water vapor in cooling air is stuck on the jackscrew 500 when the cooling air is conveyed into the cavity 120, so that the jackscrew 500 is rusted and is not easy to rotate.
In another embodiment of the present invention, the embodiment of the present invention is different from the above-mentioned embodiment in that a plurality of roller rods 400 are arranged at equal intervals, the roller rods 400 are embedded on the upper end surface of the supporting portion 111, and the roller rods 400 can rotate around the axis of the roller rods 400. Because the roller rod 400 can rotate around the shaft in situ, the friction force between the L-shaped support 200 and the roller rod 400 can be further reduced, so that the friction resistance of the expansion movement of the arch brick 4 can be reduced, the L-shaped support 200 can be pushed to stably move on the roller rod 400 when the arch brick 4 is heated to expand in the process of the roasting kiln, and the arch brick 4 is heated to uniformly expand backwards without being blocked.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
