Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to an electric furnace carbonization device. Background Art

[0002] The timing of artificial carbon addition is incorrect. For example, concentrated large-scale carbon addition in the early stage will cause the molten steel in the ladle to boil, which is easy to cause safety incidents. For example, unclear instructions received by furnace workers will cause insufficient or excessive carbon addition. At the same time, the labor intensity is high and the working environment is bad. The specific manifestations are as follows:

[0003] 1. During the electric furnace production process, it is difficult to accurately control the amount of carbon added during artificial carbon addition, which may lead to unstable composition of molten steel and affect the quality of steel.

[0005] 3. The artificial carbon addition process may produce dust and exhaust gas, causing certain pollution to the environment.

[0006] 4. Artificial carbonization requires operators to have high skills and experience, otherwise it may affect the carbonization effect. Utility Model Content

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1 As shown, an electric furnace carbon increasing device described in the utility model is installed on the equipment platform of the ladle 6, including: a carbon powder bin 1 for storing a carbon increaser, and a first gate valve 2 is provided at the discharge port of the carbon powder bin 1; a weighing hopper 9 is arranged at the discharge port of the carbon powder bin 1 for receiving the carbon increaser in the carbon powder bin 1 and weighing it; a second gate valve 3 is provided at the discharge port of the weighing hopper 9; a vibration mechanism 4 is also provided at the bottom of the weighing hopper 9; a distributor 5 is arranged at the discharge port of the weighing hopper 9, a valve 11 is provided at the discharge port of the distributor 5, and the discharge port is connected to a chute 7, and the chute 7 is arranged obliquely;

[0028] Furthermore, it also includes a control system 10, which is electrically connected to the first gate valve 2, the second gate valve 3 and the valve 11 respectively.

[0029] In this embodiment, the weighing hopper is provided with a weighing sensor 8, and the weighing sensor 8 is electrically connected to the control system 10. In this embodiment, the number of the weighing sensors 8 is two, which are symmetrically arranged on both sides of the weighing hopper 9.

[0030] Preferably, the vibration mechanism 4 includes a vibration motor and a vibration plate, the vibration plate is arranged on the side of the weighing hopper 9, the vibration plate is connected to the vibration motor, the vibration motor drives the vibration plate to vibrate, and the vibration motor is electrically connected to the control system 10.

[0031] Furthermore, the control system 10 includes a processor and a weighing module, a valve control module and a valve plate control module connected to the processor. The weighing module is used to receive the signal of the weighing sensor 8; the valve control module is used to control the opening of the valve 11, and the valve plate control module is used to control the opening and closing of the first gate valve 2 and the first gate valve 3; when the weighing module receives the signal of the weighing sensor 8, it sends it to the processor, and the processor then drives the motor control module, the valve control module and the valve plate control module to work.

[0032] Specifically, the vibration motor is connected to the motor control module of the control system 10. When the weighing sensor 8 senses that the carburizer in the weighing hopper 9 has reached a set amount, the processor controls the vibration motor to start by controlling the motor control module. The vibration plate driven by the vibration motor transports the carburizer to the distributor 5, and then the distributor 5 transports the carburizer to the chute 7.

[0033] Furthermore, the first gate valve 2 and the second gate valve 3 are both pneumatic gate valves, and the pneumatic gate valves include a cylinder and a gate, and the telescopic end of the cylinder is connected to the gate. When the telescopic rod of the cylinder is extended, the gate is controlled to be pushed out to block the discharge ports of the toner bin 1 and the weighing hopper 9, and when the telescopic rod of the cylinder is retracted, the gate is controlled to retract to open the discharge ports of the toner bin 1 and the weighing hopper 9.

[0034] Furthermore, the angle between the chute 7 and the horizontal direction is 60°. The angle design of the chute 7 facilitates the carburizer to flow smoothly from the distributor 5 into the ladle 6.

[0035] Preferably, the distributor 5 is a funnel structure, which is helpful for the convergence and outflow of the additive.

[0036] During operation, first, the carburizer is put into the carbon powder bin 1, and the control system in the operating room gives the data of the carburizer to be added. The control system 10 controls the first gate valve 2 to open, and the carburizer enters the weighing hopper 9. The weighing sensor 8 weighs the carburizer. When the target weight is reached, the first gate valve 2 is closed, and the second gate valve 3 is opened. The weighing hopper 9 discharges the material. The control system 10 controls the vibration plate driven by the vibration motor to transport the carburizer to the distributor 5, and then the distributor 5 transports the carburizer to the chute 7. Since the chute 7 is inclined at 60°, the carburizer can directly reach the discharge port through the chute 7, and evenly increase the carburizer into the ladle 6 at a suitable speed through the discharge port, thereby ensuring the process requirements and safety requirements, while reducing the burden of human labor.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
