[0004] Therefore, the utility model takes the following technical scheme:

[0005] A metallurgical furnace feeding smoke stop device, including the feeding pipe, be equipped with the pivot in the feeding pipe, the pivot is supported on the lateral wall of the feeding pipe and the one end of pivot is from the lateral wall of the feeding pipe, be equipped with the dust baffle that can rotate with the pivot on the pivot, the shape of dust baffle is consistent with the cross section at the pivot position of feeding pipe, the outer end of pivot is connected with the connecting rod for driving the pivot rotation, the one end of connecting rod away from the pivot is fixed with the counterweight, the lateral wall of the feeding pipe away from the pivot is equipped with the limit block, the one end of dust baffle away from the pivot is supported on the bottom of limit block.

[0006] Further, the pivot is horizontally arranged.

[0007] Further, the connecting rod and the dust baffle form an included angle of 30-60 degrees.

[0008] Further, the connecting rod and the pivot are arranged perpendicularly.

[0009] Further, the cross section of the feeding pipe is rectangular.

[0010] The utility model has the advantages that: the dust baffle is arranged in the feeding pipe and rotates through the connecting rod and the counterweight, and the opening and closing of the dust baffle do not need to be controlled artificially during feeding, which saves time and effort, is convenient and fast, the dust baffle can block the feeding pipe quickly after the material falls, the overflow and diffusion of smoke dust caused by untimely blocking can be effectively prevented, and the use effect is good; the structure is simple, and the manufacturing cost is low.

[0016] The present invention will now be described in detail with reference to the accompanying drawings:

[0017] like Figures 1-3 As shown, a metallurgical furnace charging and fume-blocking device includes a charging pipe 1 for charging the metallurgical furnace. The charging pipe 1 has a rectangular cross-section. A horizontally arranged rotating shaft 2 is provided inside the charging pipe 1. The rotating shaft 2 abuts against the side wall of the charging pipe 1, and one end of the rotating shaft 2 protrudes from the side wall of the charging pipe 1. A dust baffle 3 is provided on the rotating shaft 2 and can rotate with the rotating shaft 2. The shape of the dust baffle 3 is consistent with the cross-section of the charging pipe 1 at the position of the rotating shaft 2. When the dust baffle 3 is in a horizontal state, it can block the charging pipe 1, preventing the smoke and dust generated inside the charging pipe 1 during charging from spreading outward from the charging pipe 1 and polluting the surrounding environment. The outer end of the rotating shaft 2 is connected to a device for driving the charging device. The connecting rod 4 rotates the shaft 2. The connecting rod 4 is perpendicular to the shaft 2 and forms an angle of 30-60 degrees with the dust baffle 3. In this embodiment, the angle is 30 degrees. A counterweight 5 is fixed to the end of the connecting rod 4 away from the shaft 2. The counterweight 5 is used to apply external force to the connecting rod 4, so that the connecting rod 4 drives the shaft 2 to rotate. A limiting block 6 is provided on the side wall of the feeding pipe 1 away from the shaft 2. When the dust baffle 3 is in a horizontal state and blocks the feeding pipe 1, the end of the dust baffle 3 away from the shaft 2 abuts against the bottom of the limiting block 6. The limiting block 6 can restrict the dust baffle 3 from rotating upward under the drive of the connecting rod 4, and prevent it from blocking the feeding pipe 1.

[0018] The method of using this utility model is as follows:

[0019] When adding material into the kiln through the feeding pipe 1, the material is poured into the feeding pipe 1 from the top. After the material enters the feeding pipe 1 and comes into contact with the dust baffle 3, a downward external force is applied to the dust baffle 3. Under the action of the external force, the dust baffle 3 rotates downward around the pivot 2 (e.g., Figure 3When the material falls to the bottom of the hopper, the weight 5 exerts a downward force on the connecting rod 4, which in turn rotates the connecting rod 4, the rotating shaft 2 and the dust baffle 3 upward and abuts against the bottom of the limiting block 6, so that the dust baffle 3 blocks the charging pipe 1, effectively preventing smoke overflow and polluting the surrounding environment. Since the connecting rod 4 and the dust baffle 3 form an included angle, the weight 5 and the dust baffle 3 are located in the same vertical plane when the dust baffle 3 is in a vertical state, so that the connecting rod 4 cannot drive the rotating shaft 2 and the dust baffle 3 to rotate, affecting normal use.

[0020] The device is convenient to use and does not need to manually control the opening and closing of the dust baffle 3, saving time and effort. After the material falls, the dust baffle 3 can quickly block the charging pipe 1, effectively preventing smoke overflow and spreading due to untimely blocking.
