Description

Technical Field

[0001] The utility model relates to the field of blast furnace smelting, in particular to an acidic slag smelting device. Background Art

[0002] Blast furnace is an important equipment for smelting steel, which has the following functions:

[0003] 1. The blast furnace can reduce the iron oxide in the iron ore to metallic iron. In the blast furnace, coal and air enter through nozzles and react with the iron ore under high temperature conditions to reduce the iron oxide to metallic iron;

[0004] 2. Through the high temperature and smelting process of the blast furnace, the metallic iron reduced from the ore is melted into liquid iron, which is convenient for subsequent casting and molding processing;

[0005] 3. The slag generated in the blast furnace can absorb impurities such as non-ferrous metals, eventually forming slag and molten iron separated, and further processed in the converter or other smelting equipment.

[0006] In the existing technology, although a certain blast furnace smelting effect can be achieved during use, there is a defect: the existing slag smelting device lacks the function of conveniently replacing the catalyst and increasing the catalyst reaction area, resulting in low efficiency of the positive reaction during use and inability to obtain effective processing. In view of this, we propose an acidic slag smelting device to solve the above problems. Utility Model Content

[0007] The utility model aims to provide an acidic slag smelting device in view of the problems existing in the background technology.

[0008] The technical solution of the utility model is as follows: an acidic slag smelting device, comprising a box, a rotating plate and a fixed plate, wherein a rotating plate is arranged inside the box, a mounting frame 1 is arranged at the upper end of the rotating plate, a screw 2 is arranged on the outer wall of the mounting frame 1, the screw 2 is rotatably plugged into the rotating plate, a mounting frame 2 is arranged at the lower end of the rotating plate, a fixed plate is arranged on the outer wall of one side of the rotating plate, and the fixed plate is fixedly connected to the rotating plate by screw 1;

[0009] When the device is in use, the raw materials to be processed and smelted can be introduced into the interior from the feed port at the upper end of the box body, the motor and the heater are started, and under the heating treatment of the heating plate, the motor drives the rotating plate to slowly stir the internal materials. The fixed plate on one side of the rotating plate can be removed, and the catalyst to be used can be added to the rotating plate. Under the effect of continuous paving and rotation, the contact area between the catalyst and the reactant is maximized, and the forward reaction rate is optimized. When the catalyst is used up, the staff can enter from the feed port and loosen screws one and two. After screw two is loosened, the rotating plate can be rotated longitudinally by a certain angle to facilitate the pouring out of the catalyst inside the rotating plate. After adding again, screws one and two can be restored for the next step.

[0010] Preferably, a motor is disposed at the upper end of the box body, a rotating shaft is disposed at an upper end of the mounting frame, and an output shaft of the motor is fixedly connected to the upper end of the rotating shaft.

[0015] Preferably, a positioning shaft is provided at the lower end of the second mounting frame, and the positioning shaft is plugged into the bottom end of the box body.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The utility model can utilize a motor to drive the rotating plate to rotate slowly, thereby increasing the reaction area between the catalyst and the raw materials inside the box, and having a stirring effect.

[0018] 2. Based on beneficial effect 1, when replacing the catalyst, the device can open screw 2 to allow the rotating plate to rotate longitudinally to a certain angle, thereby facilitating the rapid replacement of the catalyst.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
