Problems solved by technology

The top-blowing gas-assisted desulfurization slag removal device of the hot metal tank needs to use the clamping device to lower or lift the blowing pipe, which is inconvenient to use, and the blowing pipe takes up a lot of space during the movement process and is inconvenient to install.
At the same time, the molten iron tank will rotate during the slag removal process, and the inclination angle of the molten iron tank will change, while the position and angle of the air blowing pipe cannot be adjusted, which reduces the slag removal efficiency

Embodiment Construction

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Such as figure 1 , figure 2 As shown, the blowing type slag gathering device of the present invention includes a frame 5, a first driving device 6, a swing arm 3, a connecting rod 4, a control arm 2 and an air spray gun 1.

[0018] The first driving device 6 is fixed on the frame 5, and the swing arm 3 is driven to rotate by the first driving device 6. The first driving device 6 may be an electric motor, a hydraulic motor or the like. The connecting rod 4 is hinged on the frame 5, and the two ends of the control arm 2 are respectively hinged with the connecting rod 4 and the swing arm 3. The frame 5, the swing arm 3, the connecting rod 4 and the control arm 2 form a four-bar mechanism, which is a double-rocker...

Abstract

The invention relates to a blow-boiling-type slag gathering device which is characterized by comprising a frame (5), a first driving device (6), a swing arm (3), a connecting rod (4), a control arm (2) and an air injection gun (1), wherein the connecting rod (4) is hinged on the frame (5); the first driving device (6) is fixed on the frame (5); the first driving device (6) is used for driving the swing arm (3) to rotate; two ends of the control arm (2) are respectively hinged with the connecting rod (4) and the swing arm (3); the frame (5), the swing arm (3), the connecting rod (4) and the control arm (2) form a four-rod mechanism; and the air injection gun (1) is fixedly connected with the control arm (2).

Description

technical field [0001] The invention relates to the field of molten iron pretreatment, and more specifically relates to a boiling-type slag collecting device. Background technique [0002] In the current steelmaking process, after the desulfurization of molten iron, slag removal treatment is carried out, and the slag removal treatment is all carried out with a slag removal machine. In the later stage of slag removal, because the slag is less and scattered, part of the molten iron will inevitably be removed at the same time during the slag removal process, resulting in the loss of molten iron. At the same time, due to the lack of dross in the later stage, the degree of difficulty in removing dross increases, and the dross is difficult to remove. The time for removing dross is long, which also greatly increases the sulfur return rate in the molten iron converter. [0003] The Chinese patent with the authorized notification number CN202181313 discloses a gas-assisted desulfuri...
