Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a high-titanium slag raw material pretreatment device. Background Art

[0002] High-titanium slag is the common name for titanium ore enrichment formed through a physical production process. Specifically, it is a high-titanium dioxide enrichment obtained by melting titanium ore in an electric furnace to separate titanium dioxide and iron in the titanium ore. High-titanium slag is an indispensable material in the fields of coatings, inks, papermaking, plastics and rubber, chemical fibers, ceramics, etc. It is also a basic raw material for the titanium industry. At present, in the processing of high-titanium slag, in order to prevent the high-titanium slag from exploding due to rapid temperature rise after entering the molten pool, the high-titanium slag needs to be preheated.

[0003] The utility model patent with the authorization announcement number CN217929812U discloses an energy-saving raw material preheating equipment for a high-titanium slag smelting system, which includes a preheating table and a support frame. A preheating cavity is arranged on one side of the top of the preheating table, and a plurality of electromagnetic heating coils are installed at equal distances on the inner wall of the preheating cavity. A slide rail groove is arranged on the other side of the top of the preheating table, and a transverse driving mechanism is installed in the slide rail groove. The transverse driving mechanism includes a first nut seat, and the top of the first nut seat is connected to the bottom of the support frame. The support frame is a cavity structure and a sliding groove is arranged near one end of the preheating cavity. A longitudinal driving mechanism is installed inside the support frame, and the longitudinal driving mechanism includes a second nut seat, and the side of the second nut seat is connected to the support arm. Two connecting rods are installed at the bottom of the support arm, and the bottom of the two connecting rods are both installed with a first high-temperature resistant metal frame, and the first high-temperature resistant metal frame is at the same vertical section as the preheating cavity. The horizontal driving mechanism and the longitudinal driving mechanism can realize the left and right movement of the support frame and the lifting movement of the support arm, so that the titanium slag in the high-temperature resistant metal frame enters the preheating cavity and is electromagnetically preheated by the electromagnetic heating coil, so as to prevent the titanium slag from directly entering the molten pool and bursting due to rapid temperature rise, which may cause a dangerous situation; first, the titanium slag is placed in the second high-temperature resistant metal frame, and then the second high-temperature resistant metal frame is placed in the first high-temperature resistant metal frame, and then the first servo motor is started to operate to rotate the first screw rod, and the first nut seat moves the support frame in the slide rail groove. When the support arm is located at the top of the preheating cavity, the first servo motor is stopped to operate the second servo motor, so that the second nut seat drives the support arm and the high-temperature resistant metal frame to descend, and then the electromagnetic heating coil is started to electromagnetically preheat the titanium slag in the high-temperature resistant metal frame. After the heating is completed, the support arm is raised in the same way, and the support frame moves to the other end of the preheating table. The operation is simple and does not require too much manual operation, and it is highly practical.

[0004] Although the energy-saving high-titanium slag smelting system uses raw material preheating equipment to facilitate the preheating of high-titanium slag, the device still has the following problems in actual use: during the preheating process of the device, the high-titanium slag needs to be sent into the preheating cavity through the longitudinal drive mechanism, and after the preheating is completed, it needs to rely on this mechanism to lift it out and carry out subsequent transfer. This design not only makes the preheating process of high-titanium slag cumbersome and complicated, thus affecting the overall processing efficiency; moreover, the frequent lifting and transfer of high-titanium slag also invisibly increases the safety risks in the operation process. In view of this, we propose a high-titanium slag raw material pretreatment device. Utility Model Content
