By preheating the charge, the energy consumption in the smelting process can be significantly reduced, the smelting time can be shortened, and the oxidation loss of the molten metal in a high temperature environment can be reduced, thereby improving the metal yield. This allows the charge preheater to be heated in a more uniform manner, at a higher temperature and in a shorter process. However, there are still some problems in the use of the existing charge processing preheating device: First, the device is not equipped with a charge stirring component. When the charge is in a piled state, there are a lot of gaps and dead angles inside. The bottom layer and internal charge are difficult to fully contact with the heat source, resulting in overheating of the outer layer and underheating of the inner layer, thus reducing the preheating effect of its preheating device.

[0025] The upper surface of the conveying pipe 34 is connected to a feed hopper 37, and the upper surface of the feed hopper 37 is movably connected to a dust cover 36. The feed hopper 37 is matched with the dust cover 36 to reduce dust from being blown out. The lower surface of the conveying pipe 34 is connected to a discharge pipe 303. The discharge pipe 303 facilitates the discharge of the furnace charge inside the conveying pipe 34. The upper surface of the preheating furnace body 5 is provided with a feed port 302 for use with the discharge pipe 303.

[0033] After the charge enters the preheating furnace body 5, the preheating furnace body 5 heats the charge through the built-in electric heating element, starts the servo motor 21 in the stirring assembly 2, and the output end of the servo motor 21 drives the sprocket 26 fixedly connected to it to rotate. The multiple sprockets 26 are engaged and connected by the chain 25, thereby driving the multiple stirring rods 24 to rotate. The sealing ring 27 installed on the upper surface of the preheating furnace body 5 ensures the sealing of the stirring rod 24 during rotation to prevent heat and gas leakage.

[0034] The bottom end of the stirring rod 24 is rotatably connected to the inner cavity of the preheating furnace body 5, and the stirring member 23 fixedly sleeved on the outer surface thereof rotates accordingly to stir the charge so that the charge is heated more evenly in the preheating furnace body 5.

[0035] The insulation component 4 on the outer surface of the preheating furnace body 5 is composed of a high-temperature resistant insulation material cushion cover 41, a vacuum insulation cushion cover 42, a metal reflective cushion cover 43 and a composite reflective insulation coating cushion cover 44 from the inside to the outside, which can effectively reduce heat loss, ensure the temperature inside the preheating furnace body 5, and improve the preheating efficiency.

[0036] During the preheating process, if it is necessary to discharge the gas in the preheating furnace body 5, the sealing plug 6 at the top of the exhaust pipe 7 can be opened to discharge the gas.

[0037] The operator can observe the preheating condition of the charge through the high temperature resistant glass observation window 9 in the mounting groove 8 on one side of the preheating furnace body 5 so as to adjust the preheating parameters in time.

[0038] When the charge preheating is completed, the blocking cover 11 on one side of the discharge pipe 10 is opened, and the preheated charge is discharged from the preheating furnace body 5 through the discharge pipe 10, completing the entire charge preheating process.
