Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a smelting high-temperature slag screening device. Background Art

[0002] Slag is also called molten slag. It is a melt floating on the surface of liquid materials such as metals generated during the pyrometallurgical process. It is mainly composed of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal. Slag has a wide range of uses and can be used to make cement or various fertilizers. Since slag is burned at high temperatures, it forms particles of different sizes and needs to be screened before use.

[0003] According to a Chinese patent document with announcement number CN212168135U, a screening device for high-temperature smelting slag is disclosed, which includes a base, a screening box is arranged above the base, and the screening box is connected to the base through a driving mechanism, the driving mechanism includes a support column, a connecting piece, a rotating shaft, an L-shaped connecting rod, a screw, a driving motor and a fixed plate, the screening box is movably connected to the support column and the L-shaped connecting rod through the connecting piece using a rotating shaft, the L-shaped connecting rod is threadedly connected to the screw, and the inner side of the screening box is provided with a first grading screen, a second grading screen and a holding tank. In the screening device for high-temperature smelting slag of the utility model, the driving motor drives the screw to rotate and then drives the L-shaped connecting rod to move vertically, thereby driving the screening box to swing continuously under the support of the support column, which can speed up the screening speed of the slag and thus improve the screening efficiency of the slag, and the slag is screened layer by layer through the first grading screen and the second grading screen, which can realize the function of multi-level separation of slag, and the screening effect is good.

[0004] Based on the search of the above patents and in combination with the screening devices in the prior art, it is found that when the above device is in use, the driving motor drives the screw to rotate, so that the L-shaped connecting rod moves vertically, and then the screening box is pushed to swing continuously under the support of the support column, which can speed up the screening speed of the slag and thus improve the screening efficiency of the slag. However, in actual use, it can only be carried out by moving the L-shaped connecting rod on one side, which makes the screening box shake, causing the screening box to tilt, and the unscreened slag to pile up together, resulting in a decrease in the screening speed, and the screened slag is all piled up on one side. When collecting, it is easy to cause the slag on one side to scatter, thereby reducing practicality. Utility Model Content
