[0029] The suction hood 11 serves as the initial point of the system and is responsible for collecting harmful gases and dust generated in industrial production, the cyclone separator 12 separates large particles in the inhaled gas by centrifugal force, this pretreatment step helps to reduce the burden of the subsequent purification equipment, the heat exchanger 13 is used to adjust the temperature of the gas passing through the system, which is crucial for maintaining the ideal thermal balance state of the gas in the system and helps to improve the overall processing efficiency, the main function of the mist eliminator 14 is to capture and remove mist droplets in the gas, and the bag-type dust collector 15 uses filter bags to capture tiny dust particles and is the key equipment for deep purification of waste gas in the entire system.

[0030] The protection assembly comprises a limiting rail 21, a first protection plate 22, a first sliding block 23, a first square groove 24 and a first side plate 25.

[0031] The limiting rail 21 is fixed to the upper surface of the suction hood 11, the first protection plate 22 is installed on one side of the outer surface of the limiting rail 21, the first sliding block 23 is fixedly connected to the lower surface of the first protection plate 22, the first square groove 24 is opened on one side of the outer surface of the first protection plate 22, and the first side plate 25 is fixed on one side of the outer surface of the first protection plate 22.

[0032] The first protection plate 22 and the second protection plate 27 move under the guidance of the limiting rail 21, ensuring the smooth movement of the first protection plate 22 and the second protection plate 27, the first sliding block 23, the second sliding block 271, the first roller 26 and the second roller 29 ensure that the first protection plate 22 and the second protection plate 27 can slide smoothly, reducing wear and allowing quick adjustment.

[0033] The lower surface of the first protective plate 22 is provided with a first roller 26, the outer surface of the limiting rail 21 is provided with a second protective plate 27 on the other side, the lower surface of the second protective plate 27 is fixedly provided with a second sliding block 271, the outer surface of the second protective plate 27 is provided with a second square groove 272 on one side, the outer surface of the second protective plate 27 is fixedly provided with a second side plate 28, and the lower surface of the second protective plate 27 is rotatably provided with a second roller 29.

[0035] Working principle: when the smelting waste gas of the up-drawing furnace is being pumped, the worker first pushes the first protective plate 22 to the middle, the first roller 26 rotates on the ground, the first sliding block 23 moves in the limiting rail 21, and the limiting rail 21 extends out of the first square groove 24 after being pushed to a certain position; then push the second protective plate 27, the second protective plate 27 moves to the middle under the connection of the second roller 29, and the second sliding block 271 moves in the limiting rail 21; when the first side plate 25 contacts the second side plate 28, the upper part of the up-drawing furnace can be closed.

[0036] Through accurate operation of the first protective plate 22 and the second protective plate 27, flexible closure of the upper part of the up-drawing furnace can be achieved, which not only improves the efficiency of waste gas treatment, but also significantly reduces energy consumption.

[0037] Please refer to Figures 1-4 The embodiment further comprises

[0038] The locking assembly comprises a fixed plate 31, a fixed buckle 32, a connecting block 33, a connecting shaft 34, a first clamping block 35, a first spring 36, a second clamping block 37, and a second spring 38.

[0039] The fixed plate 31 is fixed on one side of the outer surface of the first side plate 25, the fixed buckle 32 is fixedly connected on one side of the outer surface of the fixed plate 31, the connecting block 33 is fixed on one side of the outer surface of the second side plate 28, the connecting shaft 34 penetrates through the outer surface of the connecting block 33, the first clamping block 35 penetrates through the outer surface of the connecting shaft 34, the first spring 36 is connected on the outer surface of the first clamping block 35, the second clamping block 37 penetrates through the outer surface of the connecting shaft 34, and the second spring 38 is connected on the outer surface of the second clamping block 37.

[0040] During the continuous pressing process, the first spring 36 and the second spring 38 are gradually compressed, and this compression causes the first clamping block 35 and the second clamping block 37 to open outward, thereby creating space for the fixed buckle 32 to enter the clamping block.

[0041] Working principle: when the first side plate 25 and the second side plate 28 are in contact, the first fixed buckle 32 will be in contact with the first clamping block 35 and the second clamping block 37, and in the process of continuous pressing, the first spring 36 and the second spring 38 will be compressed, the first clamping block 35 and the second clamping block 37 will be opened outward, the fixed buckle 32 will be clamped into the first clamping block 35 and the second clamping block 37, when the fixed buckle 32 enters the first clamping block 35 and the second clamping block 37, the first spring 36 and the second spring 38 will quickly recover the deformation, and the fixed buckle 32 will be clamped in the first clamping block 35 and the second clamping block 37, so that the first side plate 25 and the second side plate 28 are clamped together.

[0042] This step avoids that the first protective plate 22 and the second protective plate 27 are accidentally opened when the smelting waste gas is sucked, and guarantees the continuity and safety of the suction process.

[0043] The above examples are only used to illustrate the technical scheme of the utility model, and not limit it.
