[0003] Specifically, in the prior art, most of the hoods are fixed, that is, the hood is fixed on the bracket outside the trolley. The hood of the traditional technology is not movable, and the circulating flue gas hood is provided with a layer of insulation material. The lifting weight is also relatively heavy. Therefore, the disassembly process is complicated, time-consuming and labor-intensive, which brings great inconvenience to the maintenance work. In addition, when the trolley is repaired, the connecting bolts of the trolley hood need to be opened, the sealed hood needs to be disassembled and installed, and hoisted to the sintering platform. The trouble caused by this is that even if there is a small problem with the trolley, the hood needs to be disassembled and installed back and forth, and the surface temperature of the hood is relatively high. It is necessary to wait for the temperature of the hood to drop before construction can be carried out, which wastes a lot of maintenance time. In addition, the sealed hood used in the flue gas circulation technology center needs to be insulated. The insulation forms generally include external insulation of insulation panel + insulation cotton, and internal insulation of the inner surface of the sealed hood sprayed with insulation castables. Regardless of the insulation form, the insulation of the hood will be damaged to varying degrees when the sealed hood is hoisted.

[0004] Therefore, there is an urgent need for a movable sintering flue gas circulation trolley sealing cover that can solve the problems of trolley hood maintenance and repeated lifting of the hood, shorten the maintenance time, and protect the hood's thermal insulation function.
