Description

Technical Field

[0001] This utility model relates to the field of iron removal equipment technology, specifically a carbonized slag iron removal device. Background Technology

[0002] High-temperature carbonization production lines for titanium-containing blast furnace slag are used to convert TiO2-containing blast furnace slag into TiC-containing carbide slag. However, due to the higher viscosity of titanium-containing blast furnace slag compared to ordinary blast furnace slag, the slag-iron separation effect is poor, resulting in a relatively high metallic iron content in the titanium-containing blast furnace slag. To reduce the metallic iron inclusions in the carbide slag and provide higher-quality TiC-containing raw materials for downstream processes, it is necessary to perform magnetic separation for iron removal during the storage and transportation of the carbide slag. To solve this technical problem, a carbide slag iron removal device is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the iron removal device for carbonized slag according to an embodiment of the present invention. Figure 1High-temperature carbonization production lines for titanium-containing blast furnace slag are used to convert TiO2-containing blast furnace slag into TiC-containing carbide slag. However, due to the higher viscosity of titanium-containing blast furnace slag compared to ordinary blast furnace slag, the slag-iron separation effect is poor, resulting in a relatively high metallic iron content in the titanium-containing blast furnace slag. To reduce the metallic iron inclusions in the carbide slag and provide higher-quality TiC-containing raw materials for downstream processes, it is necessary to perform magnetic separation for iron removal during the storage and transportation of the carbide slag. To solve this technical problem, a carbide slag iron removal device is proposed.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Example 1

[0023] Please see Figure 1 The present invention provides a structural diagram of a carbonized slag iron removal device according to Embodiment 1. The carbonized slag iron removal device includes: a storage bin 1, an electromagnetic suction ring 2, and a feeding device 3; the electromagnetic suction ring 2 is installed on the outer wall of the storage bin 1; the feeding device 3 is installed on the top of the storage bin 1, and the output end of the feeding device 3 is located above the opening at the top of the storage bin 1.

[0024] The feeding device 3 of this invention inputs carbide slag into the storage silo 1 at a set conveying speed. Simultaneously, the electromagnetic suction ring 2 is energized, performing slag removal treatment on the carbide slag passing through the storage silo 1, adsorbing the iron slag onto the side wall of the storage silo 1. After the feeding device 3 completes its conveying operation, it stops working, and the electromagnetic suction ring 2 is de-energized, removing the adsorbed iron slag. By installing electromagnetic suction rings on the outer wall of the storage silo 1, magnetic separation is performed on the carbide slag to remove iron, thereby reducing the metallic iron content in the slag. After magnetic separation, the metallic iron mixed in with the carbide slag can be effectively removed, reducing the metallic iron content in the carbide slag to ≤1.2%, which can improve the TiC grade in the carbide slag and provide higher-quality raw materials for downstream processes.

[0025] In a preferred embodiment of this invention, the feeding device 3 can be a variable frequency screw feeder. This allows for adjustment of the conveying speed as needed. The rotational speed of the feeding device 3 is 25–100 r / m.

[0026] The feeding device 3 includes a housing and a rotating auger rotatably disposed inside the housing. Both ends of the auger are mounted on the housing. One end of the housing has an input port, and the other end has an output port, located above the top opening of the storage hopper 1. The feeding device 3 also includes a variable frequency motor, which is fixedly mounted on the housing. The output end of the variable frequency motor is connected to the auger drive, thus achieving the variable frequency function.

[0027] In another preferred embodiment of this utility model, the feeding device 3 can also be a variable frequency conveyor belt. This allows the conveying speed to be adjusted as needed.

[0028] like Figure 1 As shown in the preferred embodiment of this utility model, the two side walls of the storage bin 1 are gradually tapered from top to bottom towards the middle, which facilitates the adsorption of iron slag by the electromagnetic suction ring 2.

[0029] In a preferred embodiment of the present invention, the electromagnetic suction ring 2 is installed on the outer side wall of the storage bin 1 by bolts.

[0030] In a preferred embodiment of this utility model, the electromagnetic chuck 2 includes an electromagnet, a battery core, and a power source; the battery core is disposed in the battery iron, the electromagnet is electrically connected to the power source, and the power source includes a current regulating device, thus facilitating the adjustment of the electromagnet current to meet the requirements of different magnetic strengths. The field strength of the electromagnetic chuck 2 is 500–3000 GS.

[0031] It should be noted that the electromagnetic chuck 2 is a device that operates using electromagnetic principles. It attracts objects by generating a magnetic force when electricity is applied, and releases them when the power is turned off, as the magnetic force disappears. The electromagnetic chuck mainly consists of an electromagnet, an iron core, and a power source. The electromagnet is the core component, controlling the generation and disappearance of the magnetic force by applying and removing electricity. The working principle of the electromagnetic chuck is that the current activates the coil inside the electromagnet. The current in the coil generates a magnetic field, which magnetizes the iron core and the soft iron plate at the bottom of the suction cup, thus generating a strong attraction force. When an object needs to be attracted, electricity is applied to activate the magnetic field; when the object needs to be released, the power is turned off to eliminate the magnetic field, allowing the object to be released smoothly.

[0032] In use, storage bin 1 can be transferred to a tank truck. Once storage bin 1 is emptied, the electromagnetic suction ring 2 is de-energized, and the metal loses its electromagnetic attraction, falling back into storage bin 1 for further collection.
