The existing ordinary suction equipment has a low suction tolerance temperature, and a grab bucket is usually used to grab high-temperature materials. However, due to the large impact force when the grab bucket grabs the material, it is easy to cause damage to the box plate in the furnace. Therefore, only the grab bucket is used to grab the thicker material on the upper layer, and the remaining material is sucked by the suction crane when it is cooled to below the tolerance temperature of the suction equipment. The problems that arise include: 1. The grab bucket grabs the material and transports it, which pollutes the environment; 2. The grab bucket has a large impact force, which is easy to cause damage to the box plate, and the grab bucket cannot complete the removal of all materials from the furnace, and needs to be used in conjunction with an ordinary suction crane; 3. There are many production processes, high labor intensity, and low efficiency.

During this process, the first bridge frame 3 and the second bridge frame 5 move according to a preset working trajectory.

[0044] Step S4, the suction process detects whether the second silo 9 is full. If it is full, record the position of the first bridge 3 and the second bridge 5 and the height of the suction pipe 11', then lift the suction pipe 11' to stop suction, and move the first bridge 3 and the second bridge 5 to the unloading position.

During the unloading process, the third valve 172 is started to realize the dust collection function of the unloading process, and the first cooler 15 and the second cooler 12 are started to cool the dust.

[0046] Step S6, during the unloading process, check whether the material in the second silo 9 has been unloaded. If not, continue unloading. If completed, lift the unloading pipe 16, start the first bridge 3 and the second bridge 5 to move to the target position, and repeat steps S3-S6 to complete all suction and unloading tasks.
