Description

Technical Field

[0001] This invention relates to the field of batching bin technology, specifically to a raw material batching bin for an electric arc furnace equipped with a belt feeder. Background Technology

[0002] In the production of smelting in an electric arc furnace, the raw materials entering the furnace must be precisely mixed in proportion according to a specific formula, including different types of ores, reducing agents, and fluxes, to ensure that the chemical reaction in the furnace proceeds stably during the smelting process and to obtain qualified ferroalloys or other smelting products. Before entering the electric arc furnace, all kinds of raw materials must be crushed and screened to form powdery and lumpy materials with relatively uniform particle size. Then, they are transported to the batching bin for mixing according to the proportion requirements. The mixed materials are finally discharged through the bottom discharge port of the bin and sent to the electric arc furnace for smelting.

[0003] Existing raw material batching bins for electric arc furnaces typically adopt a vertical cylindrical or square structure. Multiple feed inlets are located at the top of the bin, corresponding to different types of raw material inputs. A stirring device is installed inside the bin, consisting of a stirring motor and stirring blades located inside the bin. The rotation of the blades stirs and mixes the various raw materials in the bin. A discharge port is located at the bottom of the bin, and a belt feeder is installed directly below the discharge port. The mixed material is discharged through the discharge port and falls directly onto the conveyor belt of the belt feeder, which then transports it to subsequent equipment and finally into the electric arc furnace.

[0004] However, the above-mentioned batching bins have the following technical limitations in actual use: After the raw materials for the electric arc furnace are crushed, some are in powder form, such as chromite powder and coke powder, while others are in the form of small pieces, such as coke blocks and silica blocks. During the mixing process, the mixing blades mainly rely on the pushing action generated by the rotation to make the materials move. However, the particle size difference between powder and crushed stone is large. Powder is fine and easy to flow, while crushed stone has a larger mass. When crushed stone and powder coexist, the mixing speed is generally slow in order to reduce the damage to the blades. The rotation of the mixing blades can only push the surface powder and a small amount of small crushed stone along the direction of blade movement. Large crushed stone, due to its large mass and low friction with the surrounding powder, often moves slightly at the bottom or edge of the bin and cannot be effectively driven to participate in the overall mixing. Unlike liquid raw materials, which are easy to stir and mix, the above situation ultimately makes it difficult to achieve uniform mixing of powder and crushed stone in the bin. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a raw material batching bin for an electric arc furnace equipped with a belt feeder, which can thoroughly agitate the crushed stone and powdered raw materials during mixing, resulting in a more uniform mixing of the raw materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a raw material batching bin for an electric arc furnace with a belt feeder, comprising a batching bin body and a conveyor belt located below the discharge port of the batching bin body. A cover plate is installed on the upper end of the batching bin body, and a feeding shell is installed on the upper end of the cover plate. A cylinder communicating with the feeding shell is fixedly installed inside the batching bin body. A discharge port is opened on the lower arc surface of the cylinder. A sealing cylinder is rotatably installed inside the cylinder. The sealing cylinder rotates in one direction. A tilting cylinder is rotatably installed inside the sealing cylinder. An opening and a connection port are respectively opened on the outer side of the sealing cylinder and the tilting cylinder. The opening, the discharge port, and the connection port are interconnected. A rotating shaft is fixedly installed at both ends of the tilting cylinder. A motor is provided on the outer side of the batching bin body. One of the rotating shafts is fixedly connected to the output end of the motor. A connecting piece is provided between the sealing cylinder and the tilting cylinder. After the opening and the connection port are connected, the sealing cylinder and the tilting cylinder are controlled to rotate synchronously for material discharge through the cooperation of the motor and the connecting piece.

[0007] Preferably, it further includes a stirring rod rotatably installed inside the mixing hopper, the stirring rod being equipped with a turning component, and a transmission component being provided between the stirring rod and the rotating shaft.

[0008] Preferably, the feed housing includes a funnel fixedly installed on the upper end of the cover plate, the lower end of the funnel is fixedly connected to an inclined guide housing, and a feed inlet is opened on one side of the cylinder, the feed inlet being fixedly connected to the guide housing.

[0009] Preferably, multiple spiral plates are fixedly installed on the inner wall of the material turning cylinder.

[0010] Preferably, both ends of the sealing cylinder are fixedly installed with fixing rings, both fixing rings are rotatably connected to the cylinder, and both fixing rings penetrate the cylinder and are rotatably connected to the batching hopper body through a one-way bearing.

[0011] Preferably, the two rotating shafts are rotatably connected to the mixing chamber body through corresponding fixing rings. The connecting component includes multiple arc-shaped push blocks that are fixedly installed at equal intervals on the outside of the rotating shafts. Multiple mounting grooves corresponding to the positions of the arc-shaped push blocks are opened at equal intervals on the inner side of the fixing rings. Arc-shaped limiting blocks are slidably arranged in the mounting grooves. A return spring is fixedly installed between the arc-shaped limiting blocks and the mounting grooves.

[0012] Preferably, a protective shell is fixedly installed on the outside of the batching hopper, the transmission component is located inside the protective shell, the motor is fixedly installed on the protective shell, and the transmission component includes two pulleys, which are respectively sleeved on the corresponding rotating shaft and stirring rod, and a transmission toothed belt is sleeved between the two pulleys.

[0013] Preferably, the agitation assembly includes a rotating rod rotatably mounted on a stirring rod, and an agitation plate is fixedly mounted on the outer end of the rotating rod.

[0014] Preferably, the agitation assembly further includes a fixed rod fixedly installed on the inner wall of the mixing hopper. One end of the agitation rod has a circular cavity, and one end of the fixed rod is located in the circular cavity and has multiple protrusions fixedly installed at equal intervals. The end of the rotating rod located in the circular cavity has a protruding ring that matches the protrusions.

[0015] Compared with the prior art, the present invention has the following beneficial effects: To achieve segmented feeding, sealed mixing, and directional discharge of materials within the batching silo, while ensuring the silo remains relatively sealed during mixing to prevent dust escape, this invention includes a unidirectional rotating sealed cylinder inside the cylindrical container. A tilting cylinder is rotatably installed inside the sealed cylinder. When the opening connects to the connection port, the sealed cylinder and the tilting cylinder rotate synchronously via a motor and connecting components. When the opening connects to both the connection port and the discharge port, the material is discharged through the discharge port. When the opening connects to both the connection port and the inlet port, the material is introduced into the tilting cylinder through the inlet port. As the sealed cylinder and the tilting cylinder continue to rotate synchronously for a full revolution, the opening is directly above, and both the inlet and discharge ports are sealed by the cylinder wall, resulting in a relatively sealed silo. In this state, the motor controls the tilting cylinder to rotate in the opposite direction. The sealed cylinder does not rotate, and the tilting cylinder rotates independently within the sealed silo, agitating and mixing the materials inside. The materials are thoroughly lifted, scattered, and redistributed within the tilting cylinder, resulting in a more thorough and uniform mixing effect. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0019] Please see Figures 1-9 A raw material batching bin for an electric arc furnace with a belt feeder includes a batching bin body 1 and a conveyor belt 2 located below the discharge port of the batching bin body 1 (the conveyor belt 2 is existing technology, facilitating the transport of mixed raw materials). A cover plate 3 is installed on the upper end of the batching bin body 1, and a feeding shell is installed on the upper end of the cover plate 3. A cylinder 25 communicating with the feeding shell is fixedly installed inside the batching bin body 1. The feeding shell includes a funnel 4 fixedly installed on the upper end of the cover plate 3 (the output ends of multiple raw materials can be neatly arranged above the funnel 4; external conveying equipment can be a screw feeder or other conveying equipment, transporting materials according to a corresponding ratio). An inclined guide shell 19 is fixedly connected to the lower end of the funnel 4. A feed inlet 5 is opened on one side of the cylinder 25, and the feed inlet 5 is fixedly connected to the guide shell 19 (see...). Figure 3 and Figure 4 Each raw material enters the cylinder 25 through the funnel 4 and the inclined guide shell 19 via the feed inlet 5; A discharge port 6 is provided on the lower arc surface of the cylinder 25. A sealing cylinder 13 is rotatably installed inside the cylinder 25. The sealing cylinder 13 rotates in one direction. A fixing ring 12 is fixedly installed at both ends of the sealing cylinder 13. Both fixing rings 12 are rotatably connected to the cylinder 25. Both fixing rings 12 penetrate the cylinder 25 and are rotatably connected to the feeding bin 1 through a one-way bearing. A tilting cylinder 7 is rotatably installed inside the sealing cylinder 13. An opening 14 and a connecting port 8 are respectively provided on the outer side of the sealing cylinder 13 and the tilting cylinder 7. The opening 14, the discharge port 6, and the connecting port 8 are interconnected. A rotating shaft 10 is fixedly installed at both ends of the tilting cylinder 7. The two rotating shafts 10 penetrate the opposite end of the cylinder. The corresponding fixing ring 12 is rotatably connected to the batching hopper 1. A motor 30 is installed on the outside of the batching hopper 1. One of the rotating shafts 10 is fixedly connected to the output end of the motor 30. A connecting piece is provided between the sealing cylinder 13 and the tipping cylinder 7. After the opening 14 and the connecting port 8 are connected, the sealing cylinder 13 and the tipping cylinder 7 are controlled to rotate synchronously to discharge materials through the cooperation of the motor 30 and the connecting piece. The connecting piece includes multiple arc-shaped push blocks 18 that are fixedly installed at equal intervals on the outside of the rotating shaft 10. Multiple mounting grooves 15 corresponding to the positions of the arc-shaped push blocks 18 are opened at equal intervals on the inner side of the fixing ring 12. Arc-shaped limit blocks 16 are slidably arranged in the mounting grooves 15 (see Figure 6 The arc-shaped limiting block 16 is cylindrical with a right-angle notch on one side. The outer arc surface of the arc-shaped push block 18 is opposite to the arc surface of the arc-shaped limiting block 16, and the right-angle surface of the arc-shaped push block 18 is opposite to the right-angle surface of the arc-shaped limiting block 16. The outer arc surface of the arc-shaped push block 18 is also in contact with the inner wall of the fixing ring 12. A return spring 17 is fixedly installed between the arc-shaped limiting block 16 and the mounting groove 15 (the arc-shaped limiting block 16 has a groove on one side inside the mounting groove 15, one end of the return spring 17 is fixedly connected to the inner wall of the groove, and the other end is fixedly connected to the inner wall of the mounting groove 15). See [link to relevant documentation]. Figure 3 The cylinder 25 is fixed, the discharge port 6 is located directly below, and the feed port 5 is located on one side and connected to the guide shell 19. The openings 14 and 8 of the sealing cylinder 13 and the turning cylinder 7 are located directly above. The sealing cylinder 13 is in a sealed state to the discharge port 6 and the feed port 5. After the internal material turning is completed, the motor 30 is started to control the rotating shaft 10 to rotate (counterclockwise rotation; the sealing cylinder 13 rotates in one direction, counterclockwise). The rotating shaft 10 pushes the arc-shaped limit block 16 through the arc-shaped push block 18. 6 drives the fixing ring 12, which in turn drives the sealing cylinder 13 and the tipping cylinder 7 to rotate synchronously. After the sealing cylinder 13 and the tipping cylinder 7 rotate half a turn, the connecting port 8 and the opening 14 connect with the discharge port 6. At this time, the tipped material is poured out of the tipping cylinder 7. Then, the motor 30 is started to continue controlling the rotating shaft 10 to rotate counterclockwise until the connecting port 8 and the opening 14 connect with the feed port 5. The corresponding material then enters the tipping cylinder 7. The motor 30 continues to control the rotating shaft 10 to rotate counterclockwise until the connecting port 8 and the opening 14 are directly above. At this point, the state is... Figure 3As shown in the diagram, motor 30 is then started to control the rotating shaft 10 to reverse (clockwise). Since the sealing cylinder 13 can only rotate counterclockwise in one direction, it remains stationary at this time, and the rotating shaft 10... During rotation, the arc-shaped pusher 18 continuously provides a clockwise frictional thrust to the fixed ring 12, so the fixed ring 12 will not automatically rotate counterclockwise. The rotating shaft 10 drives the turning cylinder 7 to rotate (when the rotating shaft 10 rotates clockwise, the turning cylinder 7 rotates independently, the arc surface of the arc-shaped pusher 18 contacts the arc surface of the arc-shaped limit block 16, and due to the arc surface contact, a radial component force is generated, pushing the arc-shaped limit block 16 into the mounting groove 15, compressing the reset spring 17, and thus passing over the arc-shaped limit block 16 without driving the sealing cylinder 13 to rotate), turning over the internal material. At this time, the turning cylinder 7 is in a relatively sealed state. During the turning process, the powdery material is lifted but will not be scattered and pollute the environment. Multiple spiral plates 9 are fixedly installed on the inner wall of the turning cylinder 7, so that the blocky material is turned over more thoroughly and all raw materials are mixed more evenly.

[0020] It also includes a stirring rod 21 rotatably installed inside the batching silo 1. The stirring rod 21 is equipped with a turning component. The stirring rod 21 drives the turning component to rotate, which can stir the mixed materials after they are evenly mixed, so as to avoid the bridging phenomenon of the mixed materials in the batching silo 1 at the discharge port, which would affect the feeding. Also, since the motor 30 is working, the batching silo 1 will vibrate. Turning can also prevent the mixed materials from separating into powder and block materials due to vibration. A transmission component is provided between the stirring rod 21 and the rotating shaft 10. A protective shell 11 is fixedly installed on the outside of the batching hopper 1. The transmission component is located inside the protective shell 11. The motor 30 is fixedly installed on the protective shell 11. The transmission component includes two pulleys 28, which are respectively sleeved on the corresponding rotating shaft 10 and stirring rod 21. A transmission toothed belt 29 is sleeved between the two pulleys 28. The transmission component drives the stirring rod 21 to rotate while the motor 30 is working, thus performing a tumbling operation. The speed of the motor 30 is relatively slow to avoid excessive tumbling and damage to the material turning cylinder 7 caused by the lumpy gravel. Therefore, the speed of the corresponding stirring rod 21 is also relatively slow, and only slight tumbling of the material is required. The size of the pulleys 28 on the rotating shaft 10 and the stirring rod 21 is not limited. They can be set to be the same size, or the diameter of the pulley 28 on the rotating shaft 10 can be smaller than the diameter of the pulley 28 on the stirring rod 21.

[0021] As a further technical solution of the present invention, the agitation assembly includes a rotating rod 22 rotatably mounted on the stirring rod 21, and an agitation plate 20 fixedly mounted on the outer end of the rotating rod 22. The agitation assembly also includes a fixing rod 26 fixedly mounted on the inner wall of the mixing chamber 1. One end of the stirring rod 21 has a circular cavity 27, and one end of the fixing rod 26 is located in the circular cavity 27 and has a plurality of protrusions 23 fixedly mounted at equal intervals. One end of the rotating rod 22 located in the circular cavity 27 has a protruding ring 24 that matches the protrusions 23 (the protruding ring 24 is a circular ring, and a plurality of limiting grooves that match the protrusions 23 are opened at equal intervals on the circumference of the circular ring). As the rotating rod 22 rotates, it will drive the rotating rod 22 to move, and the rotating rod 22 will drive the convex ring 24 to move. As the convex ring 24 moves, it will rotate on its own through the cooperation of the convex block 23. When the rotating rod 22 rotates, it will drive the flipping plate 20 to rotate, so as to flip the mixed materials. While the flipping plate 20 moves around with the stirring rod 21, it will continuously flip itself, and perform multi-angle and multi-directional flipping and loosening of the materials in the batching bin 1. This effectively breaks the ring flow limitation formed by the single rotational motion of the flipping plate 20, so that the relatively stationary gravel at the bottom and edge of the bin is continuously flipped up.

[0022] During work: I. Initial Equipment Status Before startup, the connection port 8 of the tipping cylinder 7 and the opening 14 of the sealing cylinder 13 are both located directly above (the connection port 8 and the opening 14 are not connected to the feed port 5 and the discharge port 6, see...). Figure 3 At this time, both the feed inlet 5 and the discharge outlet 6 are sealed by the wall of the sealing cylinder 13, and the inside of the tipping cylinder 7 is empty, waiting for feeding. The sealing cylinder 13 is rotatably connected to the batching bin 1 through the fixing ring 12 and the one-way bearing, and its rotation direction is counterclockwise. II. Feeding Stage The motor 30 is started and rotated counterclockwise (this is the only direction in which the sealing cylinder 13 can rotate). The motor 30 drives the rotating shaft 10 to rotate, and the arc-shaped push block 18 fixedly installed on the outside of the rotating shaft 10 rotates accordingly. The straight surface of the arc-shaped push block 18 abuts against the straight surface of the arc-shaped limit block 16 and pushes the arc-shaped limit block 16. The arc-shaped limit block 16 drives the fixing ring 12 and the sealing cylinder 13 to rotate counterclockwise synchronously with the turning cylinder 7. When the sealing cylinder 13 and the turning cylinder 7 rotate to the position where the connecting port 8, the opening 14 and the feed port 5 are connected, the motor 30 stops. At this time, the various raw materials for electric arc furnaces after crushing (including powdered raw materials such as chromite powder and coke powder, as well as lumpy raw materials such as coke blocks and silica blocks) are conveyed to the funnel 4 according to the proportion requirements through external screw feeders or other conveying equipment. Each raw material slides from the funnel 4 along the inclined guide shell 19 into the feed inlet 5 on one side of the cylinder 25, and falls into the tipping cylinder 7 through the opening 14 and the connecting port 8, thus completing the feeding. III. Sealing and Mixing Stage After feeding is completed, the motor 30 continues to drive the rotating shaft 10 counterclockwise, and the arc-shaped push block 18 continues to push the arc-shaped limit block 16, so that the sealing cylinder 13 and the turning cylinder 7 rotate synchronously until the opening 14 and the connecting port 8 are directly above (that is, rotate a full circle and return to the initial position). At this time, the feeding port 5 and the discharge port 6 are both sealed by the cylinder wall of the sealing cylinder 13, and a relatively closed mixing chamber is formed inside the turning cylinder 7. After both the feed inlet 5 and the discharge outlet 6 are sealed, the motor 30 switches to clockwise rotation. At this time, since the sealing cylinder 13 is connected by a one-way bearing, it can only rotate counterclockwise. Therefore, the sealing cylinder 13 does not rotate. However, the turning cylinder 7 rotates independently clockwise with the rotating shaft 10 under the drive of the motor 30. The multiple spiral plates 9 fixedly installed on the inner wall of the turning cylinder 7 force the material in the cylinder to turn during the rotation. During the turning process, the material is lifted, scattered, and falls, so that the powdery material and the lumpy material are repeatedly interwoven and mixed in the turning cylinder 7. The turning cylinder 7 rotates independently in the sealed state, and the powder will not escape and pollute the environment when it is lifted. The control motor 30 runs clockwise at a low speed, so that the material in the turning cylinder 7 is repeatedly turned over for a sufficient time under the action of the spiral plate 9 until the raw materials are evenly mixed. IV. Material Discharge Stage After the mixture is evenly mixed, the motor 30 switches to rotate counterclockwise again, the arc-shaped pusher 18 pushes the arc-shaped limit block 16 again, and the sealing cylinder 13 and the turning cylinder 7 rotate counterclockwise synchronously. When the turning cylinder 7 rotates to the half-turn position, the connecting port 8, the opening 14 and the discharge port 6 are connected, and the mixture in the turning cylinder 7 is discharged through the discharge port 6 under the action of gravity. After all the mixed materials in the tipping cylinder 7 are discharged, the motor 30 continues to drive the sealing cylinder 13 to rotate synchronously with the tipping cylinder 7 in a counterclockwise direction until the opening 14 and the connecting port 8 are connected to the feed port 5. Then, feed the materials according to the above steps. V. Assisted Turning Stage During the entire operation of the motor 30, the rotating shaft 10 and its connected pulley 28 rotate. The pulley 28 drives another pulley 28 to rotate through the transmission toothed belt 29. This pulley 28 drives the stirring rod 21 connected to it to rotate. The tumbling component installed on it assists in tumbling the mixture in the lower part of the batching bin 1. The turning process is as follows: the stirring rod 21 drives the rotating rod 22 and the turning plate 20 to move circumferentially around the axis of the stirring rod 21. At the same time, the convex ring 24 at the end of the stirring rod 21 moves synchronously. When the convex ring 24 moves, it cooperates with the convex block 23, so that the convex ring 24 rotates when it moves, which in turn drives the turning plate 20 to rotate when it moves. This process turns the material in the batching bin 1 at multiple angles, effectively breaking the limitation of the annular flow formed by the single rotational motion. This process continuously turns up the relatively stationary gravel at the bottom and edge of the bin, preventing the powder and gravel from separating due to vibration, and also preventing the mixed material from forming a bridge and blockage at the discharge port. VI. Unloading Stage Then the valve at the discharge port of the batching silo 1 can be opened, and the mixed materials can be transferred via the conveyor belt 2.

These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
