Description

Technical Field

[0001] This utility model relates to the technical field of converter equipment, specifically a converter equipment that facilitates material feeding and discharging. Background Technology

[0002] Converter steelmaking is a traditional steelmaking method, primarily achieved through an oxygen converter. It is an indispensable part of the modern steel industry and holds a significant position in global steel production. With technological advancements, converter steelmaking is continuously being optimized and improved to meet the demands for more efficient and environmentally friendly production.

[0003] In converter steelmaking, steel is usually poured directly into the converter. However, pouring too much steel at once can sometimes hinder melting, and the varying impurities in the steel make it difficult to control the amount of steel tapped each time. Deoxidation and alloying during tapping is a relatively independent yet crucial step. To ensure successful casting or refining in the next stage, a certain amount of deoxidizing alloy is added during tapping, depending on the steel grade, to achieve the specified deoxidation level. Simultaneously, the content of silicon, manganese, and other elements in the molten steel must meet the required specifications to achieve alloying. In traditional steelmaking process control, the amount of alloy added is usually determined by operators' experience and calculated using ratios, resulting in significant errors. Utility Model Content

[0004] The purpose of this invention is to provide a converter device that facilitates material feeding and discharging, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a converter device for convenient feeding and discharging, comprising a furnace body, wherein the furnace body is composed of a converter and a top plate, and a control unit is provided on the top surface of the top plate;

[0006] The control unit includes:

[0007] The positioning rod is used for vertical positioning when the control panel descends;

[0008] The cylinder is used to control the panel to move vertically downwards stably, and it is also used to connect the top plate to the control panel.

[0009] The hopper is used to feed steel through the control panel into the converter.

[0010] The fixed plate is used to control the amount of steel entering the converter.

[0011] Preferably, a positioning rod is fixedly connected to the top surface of the top plate, and a control panel is slidably connected to the top end of the positioning rod. When the steel material is fed into the hopper by the conveying equipment, the sealing plate will approach the axis of the control panel, and the six sets of sealing plates will completely seal the control panel, so that the steel material cannot pass through the control panel and enter the converter. A cylinder is fixedly connected to the top surface of the top plate, and the output shaft of the cylinder is fixedly connected to the bottom surface of the control panel.

[0012] Preferably, a hopper is fixedly connected to the top surface of the control panel, a fixed plate is fixedly connected inside the control panel, a turntable is rotatably connected inside the control panel, and a turning groove is provided on the top surface of the turntable.

[0013] Preferably, a sealing plate is slidably connected through the inner side of the fixed disk. When the cylinder rises, the spring pushes the rotating sleeve to reset, causing the rotating sleeve to rotate in the opposite direction. Then the sealing plate will seal the control disk again. By starting the cylinder and rotating the rotating sleeve at a fixed angle each time, the sealing plate can be opened and closed stably, thereby achieving the effect of quantitatively feeding steel into the converter. A lever is slidably connected through the bottom surface of the sealing plate, and the bottom end of the lever is inserted into the inner side of the lever groove.

[0014] Preferably, a sleeve is fixedly connected to the bottom surface of the control panel, and an abutment rod is fixedly connected to the inner side of the sleeve. When the cylinder is activated, the output shaft of the cylinder pulls the control panel downward. As the control panel moves downward, the turntable inside the control panel moves downward along with the rotating sleeve via a support rod and a spring. After the ball bearings on the bottom surface of the base plate are in contact with the top plate, the control panel continues to move downward, which in turn moves the abutment rod inside the sleeve downward. A support rod is fixedly connected to the bottom surface of the turntable, and the bottom end of the support rod passes through and is slidably connected to the rotating sleeve. A spring is fixedly connected between the support rod and the inner side of the rotating sleeve.

[0015] Preferably, the outer surface of the rotating sleeve is provided with an arc-shaped groove. When the control disk continues to move downward, it will drive the abutment rod on the inner side of the sleeve to move downward together. The abutment rod is inserted into the arc-shaped groove, so that the abutment rod abuts against the arc-shaped groove and forces the rotating sleeve to rotate. When the rotating sleeve rotates, it will drive the turntable to rotate through the support rod. The abutment rod is inserted into the arc-shaped groove opened on the surface of the rotating sleeve. The bottom surface of the rotating sleeve is fixedly connected to a base plate, and the bottom surface of the base plate is provided with ball bearings.

[0016] Preferably, a discharge pipe extends through the surface of the converter, a baffle is fixedly connected to the discharge pipe, and a discharge through hole is provided on the inner side of the discharge pipe.

[0017] Compared with the prior art, this utility model provides a converter device that facilitates material feeding and discharging, and has the following beneficial effects:

[0018] 1. This convenient converter device for feeding and discharging materials, when the turntable rotates, will drive the actuating groove on the top surface to actuate the lever, causing the lever to gradually move the sealing plate from inside the fixed plate to the outside of the fixed plate. This allows the six sets of sealing plates to gradually unseal the control plate, so that the steel can fall into the converter. When the cylinder rises, the spring will push the rotating sleeve to reset, causing the rotating sleeve to rotate in the opposite direction. Then the sealing plate will reseal the control plate. By starting the cylinder and rotating the rotating sleeve at a fixed angle each time, the sealing plates can be opened and closed stably, thus achieving the effect of quantitatively feeding steel into the converter. This avoids the accumulation of steel due to excessive steel feeding at one time, which makes it difficult to melt. At the same time, it can also more accurately control the amount of steel to be melted.

[0019] 2. This converter device, which facilitates material loading and unloading, allows deoxidizing alloys to be placed into the hopper after steelmaking. By quantitatively adding deoxidizing alloys, the manual calculation of the ratio of total molten steel to deoxidizing alloys can be reduced. This ensures that deoxidizing alloys are added quantitatively and gradually each time, which is more effective in guaranteeing deoxidation and alloying during steel tapping. It also avoids the problem of uncoordinated ratio control due to adding deoxidizing alloys during tapping, which would affect the quality of the tapped steel. Attached Figure Description

[0026] like Figures 1-5As shown, this utility model provides a technical solution: a converter device for convenient feeding and discharging, including a furnace body, which is composed of a converter 1 and a top plate 3. The top surface of the top plate 3 is provided with a control unit 2. The control unit 2 includes: a positioning rod 21, a control disc 22, a cylinder 23, a hopper 24, a fixed disc 25, a turntable 26, a turning groove 27, a sealing plate 28, a turning rod 29, a sleeve 210, a rotating sleeve 211, a support rod 212, a spring 213, an arc groove 214, a bottom plate 215, a ball bearing 216, a discharge pipe 217, a baffle 218, a discharge through hole 219, and a contact rod 220.

[0027] A positioning rod 21 is fixedly connected to the top surface of the top plate 3. The top end of the positioning rod 21 is slidably connected to a control disk 22. Steel is fed into the hopper 24 by a conveying device. At this time, the sealing plate 28 will approach the axis of the control disk 22, and the six sets of sealing plates 28 will completely seal the control disk 22, preventing the steel from passing through the control disk 22 and entering the converter 1. A cylinder 23 is fixedly connected to the top surface of the top plate 3, and the output shaft of the cylinder 23 is fixedly connected to the bottom surface of the control disk 22. The hopper 24 is fixedly connected to the top surface of the control disk 22. A fixed disk 25 is fixedly connected inside the control disk 22, and a turntable 26 is rotatably connected inside the control disk 22. The top surface of the turntable 26 has a toggle groove 27. A sealing plate 28 is slidably connected through the inner side of the fixed plate 25. When the cylinder 23 is raised, the spring 213 will push the rotating sleeve 211 to reset, causing the rotating sleeve 211 to rotate in the opposite direction. Then the sealing plate 28 will seal the control plate 22 again. By starting the cylinder 23 and rotating the rotating sleeve 211 at a fixed angle each time, the sealing plate 28 can be opened and closed stably, thereby achieving the effect of quantitatively feeding steel into the converter 1. A lever 29 is slidably connected through the bottom surface of the sealing plate 28. The bottom end of the lever 29 is inserted into the inner side of the lever groove 27. A sleeve 210 is fixedly connected to the bottom surface of the control panel 22. An abutment rod 220 is fixedly connected to the inner side of the sleeve 210. When the cylinder 23 is activated, the output shaft of the cylinder 23 pulls the control panel 22 downward. As the control panel 22 moves downward, the turntable 26 inside the control panel 22 will drive the rotating sleeve 211 to move downward together through the support rod 212 and the spring 213. After the ball bearing 216 on the bottom surface of the base plate 215 is in contact with the top plate 3, the control panel 22 continues to move downward, which will drive the abutment rod 220 on the inner side of the sleeve 210 to move downward together. The support rod 212 is fixedly connected to the bottom surface of the turntable 26. The bottom end of the support rod 212 passes through and is slidably connected to the rotating sleeve 211. A spring 213 is fixedly connected between the support rod 212 and the inner side of the rotating sleeve 211. An arc-shaped groove 214 is formed on the outer surface of the rotating sleeve 211. As the control disc 22 continues to move downward, it will cause the abutment rod 220 on the inner side of the sleeve 210 to move downward as well. The abutment rod 220 is inserted into the arc-shaped groove 214, causing the abutment rod 220 to abut against the arc-shaped groove 214 and forcing the rotating sleeve 211 to rotate. When the rotating sleeve 211 rotates, it will drive the turntable 26 to rotate through the support rod 212. The abutment rod 220 is inserted into the arc-shaped groove 214 formed on the surface of the rotating sleeve 211. A base plate 215 is fixedly connected to the bottom surface of the rotating sleeve 211, and a ball bearing 216 is provided on the bottom surface of the base plate 215. A discharge pipe 217 penetrates through the surface of the converter 1. A cover 218 is fixedly connected to the discharge pipe 217, and a discharge through hole 219 is formed on the inner side of the discharge pipe 217.

[0028] Based on the above implementation method, when using the converter device, the converter 1 is first connected to the steelmaking equipment. When feeding scrap steel, the steel is fed into the hopper 24 by the conveying equipment. At this time, the sealing plate 28 will approach the axis of the control plate 22, and the six sets of sealing plates 28 will completely seal the control plate 22, so that the steel cannot pass through the control plate 22 and enter the converter 1. Then, the cylinder 23 is activated, so that the output shaft of the cylinder 23 pulls the control plate 22 downward. At the same time as the control plate 22 moves downward, the turntable 26 inside the control plate 22 will drive the rotating sleeve 211 to move downward together through the support rod 212 and the spring 213. After the ball bearing 216 on the bottom surface of the bottom plate 215 is in contact with the top plate 3, the control plate 22 continues to move downward, which will drive the abutment rod 220 on the inner side of the sleeve 210 to move downward together. The abutment rod 220 is inserted into the arc groove 214, so that the abutment rod 220 abuts the arc groove 214 and forces it downward. The rotating sleeve 211 rotates, which in turn drives the turntable 26 to rotate via the support rod 212. The turntable 26 then rotates, causing the actuating groove 27 on the top surface to actuate the lever 29. This causes the lever 29 to move the sealing plate 28 gradually from inside the fixed plate 25 to the outside of the fixed plate 25. As a result, the six sets of sealing plates 28 gradually stop sealing the control plate 22, allowing the steel to fall into the converter 1. When the cylinder 23 rises, the spring 213 pushes the rotating sleeve 211 back to its original position, causing it to rotate in the opposite direction. The sealing plates 28 then re-seal the control plate 22. By starting the cylinder 23 and rotating the rotating sleeve 211 at a fixed angle each time, the sealing plates 28 can open and close stably, achieving the effect of quantitatively feeding steel into the converter 1. This avoids excessive steel input at once, which can lead to steel accumulation and difficulty in smelting, and also allows for more accurate control of the amount of steel smelted.

[0029] After steelmaking is completed, deoxidizing alloy can be placed into hopper 24. By quantitatively adding deoxidizing alloy, the manual calculation of the ratio of total molten steel to deoxidizing alloy can be reduced. This allows for quantitative and gradual addition of deoxidizing alloy each time, which more effectively ensures deoxidation and alloying during steel tapping and avoids the uncoordinated ratio control caused by adding deoxidizing alloy during tapping, thus affecting the quality of the tapped steel.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
