[0013] 1. The automatic feeding machine for a submerged arc furnace described in this utility model supports the housing by setting up a support plate and support legs. A set of casters at the bottom of the support legs facilitates movement of the equipment. Operators can move the equipment directly above the submerged arc furnace. Since many submerged arc furnaces are now relatively small, this device can be pushed directly above the furnace. Material is then added to the feeding plate inside the housing via an existing feeding mechanism. A power unit controls the movement of a first movable plate to assist the feeding plate in dispensing material. The feeding plate has a pair of discharge ports, located on the far left and far right respectively. When material is fed into the housing and reaches the feeding plate, the power unit drives the first movable plate to move, pushing the material onto the feeding plate and causing it to fall into the submerged arc furnace.

During operation, the support plate 1 and support legs 2 can support the box 4, and the universal wheels 3 at the bottom end of the set of support legs 2 facilitate the movement of the equipment. The operator can move the equipment directly onto the submerged arc furnace. Because many electric arc furnaces are now relatively small, this device can be pushed directly above the furnace. Material is then added to the feeding plate 8 inside the housing 4 via the existing feeding mechanism. The power unit controls the movement of the first movable plate 9 to assist the feeding plate 8 in discharging material. The feeding plate 8 has a pair of discharge ports, located on the far left and far right respectively. When material is fed into the housing 4 and onto the feeding plate 8, the power unit moves the first movable plate 9, pushing the material on the feeding plate 8 and causing it to fall into the electric arc furnace. When the first movable plate 9 moves to the far left, material is added to the feeding plate 8 again. When the first movable plate 9 returns, it pushes the material to the far right, creating a regular feeding process and controlling the amount and speed of material feeding.

[0024] The power component includes a motor 10; the motor 10 is fixed to one side of the housing 4 via a fixing rod; the output end of the motor 10 is provided with a reciprocating screw 11, and one end of the reciprocating screw 11 passes through the interior of the housing 4 and is rotatably connected to one side of the interior of the housing 4; the first movable plate 9 is screw-connected to the reciprocating screw 11; a triangular baffle 12 is fixedly connected inside the housing 4. During operation, by fixing the motor 10 to one side of the housing 4 and setting the reciprocating screw 11 at the output end of the motor 10, the reciprocating screw 11 drives the first movable plate 9 to move, so that the first movable plate 9 can form a reciprocating motion on the feeding plate 8 to complete the feeding work of the electric arc furnace. The moving speed of the first movable plate 9 can be adjusted by the motor 10.

[0025] A first groove 13 is provided on one side of the box body 4; a second movable plate 14 is slidably connected in the first groove 13; a first connecting plate 15 is fixedly connected to both sides of the second movable plate 14; a pair of first connecting plates 15 are slidably connected to the inside of the box body 4 on both sides; a pair of fluidizing plates 16 are fixedly connected to the top of the second movable plate 14; a rotating shaft 17 is rotatably connected inside the box body 4, and one end of the rotating shaft 17 passes through the box body 4; a turntable 18 is fixedly connected to one end of the rotating shaft 17; a set of conical blocks 19 are fixedly connected to the turntable 18; a set of conical blocks 19 are rotatably connected to the bottom of the second movable plate 14; a transmission component is provided on one side of the box body 4; the transmission component... The component is used to drive the rotating shaft 17. During operation, a first groove 13 is opened on one side of the housing 4, and a second movable plate 14 is set in the first groove 13.

[0026] The transmission component includes a first synchronous pulley 20; the first synchronous pulley 20 is fixedly connected to the reciprocating lead screw 11; a second synchronous pulley 21 is fixedly connected to the rotating shaft 17; the first synchronous pulley 20 and the second synchronous pulley 21 are connected by a synchronous belt 22. During operation, by fixing the first synchronous pulley 20 to the reciprocating lead screw 11, fixing the rotating shaft 17 to the second synchronous pulley 21, and then driving through the synchronous belt 22, the overall structure of the system can be simplified, the number of transmission components and connecting parts can be reduced, thereby reducing the complexity and failure rate of the system.

[0027] Dust collection boxes 23 are fixedly connected to both sides of the box body 4; a pair of dust collection boxes 23 are fixedly connected to one side of each side of the box body 4; a pair of support columns 24 are fixedly connected to the support plate 1.

[0029] Working Principle: The support plate 1 and support legs 2 support the housing 4. A set of casters 3 at the bottom of the support legs 2 facilitates movement of the equipment. The operator can move the equipment directly above the electric arc furnace. Since many electric arc furnaces are now relatively small, this device can be pushed directly above them. Material is then added to the feeding plate 8 inside the housing 4 via the existing feeding mechanism. The power unit controls the movement of the first movable plate 9 to assist the feeding plate 8 in discharging material. The feeding plate 8 has a pair of discharge ports, located on the far left and far right respectively. Once the material is fed into the housing 4 and onto the feeding plate 8, the moving plate... The force-driven component moves the first movable plate 9, pushing the material on the feeding plate 8 and causing it to fall into the electric arc furnace. When the first movable plate 9 moves to the leftmost position, the feeding plate 8 is replenished with material. When the first movable plate 9 returns, it pushes the material to the rightmost position. This allows for a regular feeding process, controlling the amount and speed of material feeding. By fixing a motor 10 to one side of the housing 4 and setting a reciprocating screw 11 at the output end of the motor 10, the first movable plate 9 is moved, causing it to reciprocate on the feeding plate 8 to complete the feeding operation of the electric arc furnace. The moving speed of the first movable plate 9 can be adjusted by the motor 10. A first groove 13 is opened on one side of the housing 4, and a second movable plate 14 is set in the first groove 13. A pair of first connecting plates 15 can support the second movable plate 14. The material can enter the housing 4 through the second movable plate 14. A pair of fluidizing plates 16 can make the material form a flow trajectory on the second movable plate 14, preventing the material from falling onto the feeding plate 8 too quickly. The conical block 19 set on the turntable 18 can drive the transmission component to make the second movable plate 14 vibrate in the first groove 13, so that the material on the second movable plate 14 can flow normally on the second movable plate 14. There will be no blockage. By fixing the first synchronous pulley 20 to the reciprocating screw 11 and the second synchronous pulley 21 to the rotating shaft 17, and then driving through the synchronous belt 22, the overall structure of the system can be simplified, the number of transmission parts and connecting parts can be reduced, thereby reducing the complexity and failure rate of the system. By fixing the dust collection boxes 23 to both sides of the housing 4, the dust in the material can be adsorbed to prevent excessive dust from entering the electric arc furnace, avoiding hard slag formation in the electric arc furnace, increasing the erosion of the furnace lining and the difficulty of cleaning. By hinged a pair of sealing plates 25 at the top of the housing 4, the sealing plates 25 can be opened when needed, making it convenient for staff to maintain the inside of the equipment.
