[0002] In the steelmaking process, the precise and efficient addition of auxiliary materials plays a crucial role in ensuring steel quality and optimizing the steelmaking process. In practical applications, auxiliary material addition devices for steelmaking typically require the following technologies:
[0003] 1. Precise metering technology: Using equipment such as electronic scales and volumetric measuring instruments to accurately measure the quantity of added auxiliary materials;
[0004] 2. Conveying technology: Pneumatic conveying, screw conveying and other methods are used to transport the metered auxiliary materials into the steelmaking furnace.
[0005] Existing Chinese patent: An automated auxiliary material adding device for steelmaking converters, publication number: CN217077667U, includes an auxiliary material adding device body. A fixing plate is provided on the upper surface of the auxiliary material adding device body, and a connecting pipe is provided on the upper surface of the auxiliary material adding device body. The metering mechanism is located on the upper surface of the connecting pipe. This automated auxiliary material adding device for steelmaking converters, by setting a feeding cup, allows for accurate addition of auxiliary materials. First, by pushing the handle, the insert plate closes at the bottom of the feeding cup. Then, the auxiliary material is added inside the feeding cup. A scale is provided on the outside of the feeding cup for easy observation of the quantity inside. This device facilitates accurate addition of auxiliary materials.
[0006] However, during the implementation of the above technical solution, at least the following technical problems were found: The above-mentioned adding device requires manual control of the opening and closing of the material cup by inserting and unplugging the insert plate so that the auxiliary material can enter and exit the material cup. The degree of automation is low, which increases the labor intensity and labor costs. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a steelmaking auxiliary material adding device, which solves the technical problem that the above-mentioned adding devices require manual control of the opening and closing of the material cup by inserting and pulling the insert plate to allow the auxiliary material to enter and exit the material cup, resulting in low automation, increased labor intensity, and higher labor costs.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A steelmaking auxiliary material adding device includes a base, a spiral feeding cylinder rotatably mounted on the base, a spiral feeding rod fixedly mounted inside the spiral feeding cylinder, a first stepper motor fixedly mounted on the side end of the spiral feeding cylinder, a bevel gear set installed between the output end of the first stepper motor and the spiral feeding rod, storage bins evenly fixedly mounted on the base, supports evenly fixedly mounted on the base, quartz tubes fixedly mounted on the supports, insert plates symmetrically slidably mounted at both ends of the supports, pull rods rotatably mounted on the side ends of the insert plates, a second stepper motor fixedly mounted on the supports, a pull tube fixedly mounted on the output shaft of the second stepper motor, the two pull rods and the pull tube slidably connected, a collar slidably mounted on the supports, a laser emitter fixedly mounted on the collar, and a photosensitive sensor fixedly mounted on the collar.
[0010] Preferably, a threaded rod is rotatably mounted on the support.
[0011] Preferred: Threaded rod and collar threaded connection.
[0012] Preferably, a support wheel is rotatably mounted on the spiral feed cylinder.
[0013] Preferably, a third motor is fixedly installed on the base.
[0014] Preferably, a spur gear set is installed between the third motor and the screw feed cylinder.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. After the opening of the spiral feed cylinder is aligned with the support, the second stepper motor starts to drive the tube to rotate clockwise. Figure 4(View from above) Rotating the pull tube clockwise will cause the upper pull rod to slide the insert plate to the right, while the lower pull rod will push the lower insert plate to the left. The upper insert plate sliding to the right will open the opening at the top of the quartz tube, and the lower insert plate sliding to the left will close the opening at the bottom of the quartz tube. After the top of the support is open, the auxiliary material in the storage bucket will enter the quartz tube along the top of the quartz tube. The light emitted by the laser emitter will pass through the quartz tube and reach the photosensitive sensor. The photosensitive sensor will determine that the required quantity has not been reached when it receives the light emitted by the laser emitter. When the auxiliary material in the quartz tube accumulates to the required height, the auxiliary material will block the light emitted by the laser emitter. After the photosensitive sensor no longer receives the light emitted by the laser emitter, it will... Once the material quantity is determined to be within the standard range, the second stepper motor drives the pull tube to rotate counterclockwise. The pull tube will cause the two insert plates to reset, at which point the top of the quartz tube will be closed and the bottom of the quartz tube will be opened. At this point, the auxiliary material in the storage bucket will no longer enter the quartz tube, while the auxiliary material in the quartz tube will enter through the opening of the spiral feeding cylinder. The rotating spiral feeding rod will feed the auxiliary material into the steelmaking furnace. Since the threaded rod is threadedly connected to the collar, rotating the threaded rod can cause the collar to slide, thus controlling the height of the collar to control the quantity of auxiliary material. The laser emitter automatically adjusts the position of the two insert plates and controls the opening and closing of the openings at both ends of the quartz tube, achieving the effect of reducing labor intensity and labor costs.
[0017] II. During operation, the first stepper motor starts and drives the screw feeder to rotate via a bevel gear set. The third motor starts and drives the screw feeder cylinder to rotate via a spur gear set, aligning the feed hole of the screw feeder cylinder with different supports. After the supports open, the auxiliary materials can enter the screw feeder cylinder. The rotating screw feeder will discharge the incoming auxiliary materials through the opening at the end of the screw feeder cylinder towards the steelmaking furnace for addition. The third motor starts and drives the screw feeder cylinder to rotate via a spur gear set, which can make the feed hole of the screw feeder cylinder align with different supports, so that various auxiliary materials can be added without moving the device.

[0026] This application embodiment provides a steelmaking auxiliary material adding device, which effectively solves the technical problems of the above-mentioned adding devices, which require manual control of the opening and closing of the material cup by inserting and pulling the insert plate to allow the auxiliary material to enter and exit the material cup, resulting in low automation, increased labor intensity, and increased labor costs. After the opening of the spiral feeding cylinder is aligned with the support, the second stepper motor starts to drive the pulling tube to rotate clockwise. Figure 4(View angle) Rotating the pull tube clockwise will cause the upper pull rod to slide the insert plate to the right, while the lower pull rod will push the lower insert plate to the left. The upper insert plate sliding to the right will open the opening at the top of the quartz tube, and the lower insert plate sliding to the left will close the opening at the bottom of the quartz tube. After the top of the support is open, the auxiliary material in the storage bucket will enter the quartz tube along the top of the quartz tube. The light emitted by the laser emitter will pass through the quartz tube and reach the photosensitive sensor. The photosensitive sensor will receive the light emitted by the laser emitter and determine its position. If the required quantity is not reached, when the auxiliary material in the quartz tube accumulates to the required height, it will block the light emitted by the laser emitter. Once the photosensitive sensor no longer receives the laser light, it will determine that the material quantity has reached the standard. At this point, the second stepper motor drives the tube puller to rotate counterclockwise. The puller will cause the two insert plates to reset, sealing the top of the quartz tube and opening the bottom. At this time, the auxiliary material in the storage bin will no longer enter the quartz tube, and the auxiliary material in the quartz tube will move along the spiral feed cylinder... The rotating screw feeder delivers auxiliary materials into the steelmaking furnace through an opening. Because the screw feeder is threadedly connected to the collar, rotating the screw feeder causes the collar to slide, controlling its height and thus the quantity of auxiliary materials. A laser emitter automatically adjusts the position of the two insert plates and controls the opening and closing of the quartz tube, reducing labor intensity and costs. During operation, the first stepper motor drives the screw feeder to rotate via a bevel gear set. The third motor then drives the screw feeder cylinder to rotate via a spur gear set, aligning the feed hole of the screw feeder cylinder with different supports. Once the supports open, the auxiliary materials enter the screw feeder cylinder. The rotating screw feeder then discharges the incoming auxiliary materials through the opening at the end of the screw feeder cylinder into the steelmaking furnace. The third motor's operation, with the spur gear set aligning the feed hole with different supports, allows for the addition of various auxiliary materials without moving the device.
[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem that the above-mentioned adding device requires manual control of the opening and closing of the material cup by inserting and unplugging the insert plate to allow the auxiliary material to enter and exit the material cup. This results in a low degree of automation, increased labor intensity, and higher labor costs. The overall idea is as follows:
[0029] To address the problems existing in the prior art, this utility model provides a steelmaking auxiliary material adding device, including a base 1, a spiral feeding cylinder 2 rotatably mounted on the base 1, a spiral feeding rod 3 fixedly mounted inside the spiral feeding cylinder 2, a first stepper motor 4 fixedly mounted on the side end of the spiral feeding cylinder 2, a bevel gear set 5 installed between the output end of the first stepper motor 4 and the spiral feeding rod 3, storage bins 6 evenly fixedly mounted on the base 1, and support seats 7 evenly fixedly mounted on the base 1.
[0030] A quartz tube 8 is fixedly installed on the support 7. Insert plates 9 are symmetrically slidably installed at both ends of the support 7. A pull rod 11 is rotatably installed on the side end of the insert plate 9. A second stepper motor 12 is fixedly installed on the support 7. A pull tube 13 is fixedly installed on the output shaft of the second stepper motor 12. The two pull rods 11 and the pull tube 13 are slidably connected.
[0031] A collar 14 is slidably mounted on the support 7. A laser emitter 15 is fixedly mounted on the collar 14. A photosensitive sensor 16 is fixedly mounted on the collar 14. A threaded rod 17 is rotatably mounted on the support 7. The threaded rod 17 and the collar 14 are threadedly connected. A support wheel 18 is rotatably mounted on the spiral feed cylinder 2. A third motor 19 is fixedly mounted on the base 1. A spur gear set 21 is installed between the third motor 19 and the spiral feed cylinder 2.
[0032] Base 1: Serves as the basic support structure for the entire device, providing installation positions for other components such as the screw feeder 2, storage tank 6, and support 7, ensuring the overall stability of the device.
[0033] Spiral feed cylinder 2: It can discharge the auxiliary materials entering the cylinder to the steelmaking furnace through the end opening, realizing the conveying and addition of auxiliary materials. At the same time, it rotates under the drive of the third motor 19 and the spur gear set 21, so that the feed hole is aligned with different support 7 to receive the auxiliary materials in different storage tanks 6. The support wheel 18 is rotatably installed on the spiral feed cylinder 2, which helps it to rotate smoothly.
[0034] Spiral feeder 3: Driven by the first stepper motor 4 through the bevel gear set 5, it rotates and pushes the auxiliary material entering the spiral feeder cylinder 2 along the cylinder body and discharges it from the end opening, thus completing the action of adding auxiliary material to the steelmaking furnace.
[0035] Step 1: After starting, the stepper motor 4 transmits power to the screw feed rod 3 through the bevel gear set 5, driving the screw feed rod 3 to rotate, thereby realizing the conveying of auxiliary materials;
[0036] Bevel gear set 5: Changes the direction of power transmission, so that the first stepper motor 4 can effectively drive the screw feed rod 3 to rotate;
[0037] Storage hopper 6: Used to store different types of steelmaking auxiliary materials, providing a material source for the entire addition process;
[0038] Support 7: Supports the quartz tube 8. Insert plates 9 can be slidably installed at both ends of the support. It is equipped with components such as the second stepper motor 12, the pull tube 13, and the threaded rod 17. It is one of the key structures for controlling the entry of auxiliary materials into the screw feed cylinder 2.
[0039] Quartz tube 8: Serves as a channel for auxiliary materials to enter the spiral feed cylinder 2. Its top and bottom openings are controlled by the insert plate 9. When the top opening is open and the bottom opening is closed, the auxiliary materials in the storage tank 6 can enter the quartz tube 8. When the top opening is closed and the bottom opening is open, the auxiliary materials in the quartz tube 8 can enter the spiral feed cylinder 2.
[0040] Insert plate 9: Connected to pull tube 13 via pull rod 11, it controls the opening and closing of the top and bottom openings of quartz tube 8 under the drive of the second stepper motor 12, thereby controlling the entry and exit of auxiliary materials;
[0041] Pull rod 11: Driven by pull tube 13, it pulls or pushes insert plate 9 to slide, thereby controlling the opening of quartz tube 8;
[0042] The second stepper motor 12: after starting, drives the pull tube 13 to rotate, and drives the insert plate 9 to slide through the pull rod 11, thereby controlling the opening and closing of the openings at both ends of the quartz tube 8, realizing the automated control of the auxiliary materials entering and leaving the quartz tube 8.
[0043] Pull tube 13: When rotating, it pulls or pushes the insert plate 9 through the sliding connection with the pull rod 11 to complete the control action of the opening of the quartz tube 8;
[0044] Collar 14: can slide up and down under the drive of threaded rod 17, used to adjust the height of laser emitter 15 and photosensitive sensor 16, thereby controlling the amount of auxiliary material entering quartz tube 8;
[0045] Laser emitter 15: The emitted light passes through the quartz tube 8 and is directed to the photosensitive sensor 16. When the height of the auxiliary material inside the quartz tube 8 reaches a certain level and blocks the light, the photosensitive sensor 16 triggers the adjustment of the position of the insert plate 9, thereby realizing the automatic control of the opening of the quartz tube 8 and thus controlling the amount of auxiliary material added.
[0046] Photosensitive sensor 16: Receives the light emitted by laser emitter 15. When the light is blocked by the auxiliary material in quartz tube 8 and cannot be received, it determines that the feeding quantity has reached the standard, feeds back a signal to the control system, causes the second stepper motor 12 to move, controls the insert plate 9 to reset, and completes the automatic detection and control of the amount of auxiliary material added.
[0047] Threaded rod 17: When rotated, the collar 14 can slide up and down along the support 7, thereby adjusting the height of the laser emitter 15 and the photosensitive sensor 16, so as to control the amount of auxiliary material entering the quartz tube 8;
[0048] Support wheel 18: Provides support for the rotation of the screw feed cylinder 2, making it more stable during rotation and ensuring the stability of auxiliary material conveying;
[0049] The third motor 19: After starting, it drives the spiral feeding cylinder 2 to rotate through the spur gear set 21, so that the feeding hole of the spiral feeding cylinder 2 can be aligned with different support seats 7 to realize the addition of different auxiliary materials.
[0050] Spur gear set 21: Connects the third motor 19 and the screw feed cylinder 2, and transmits the power of the third motor 19 to the screw feed cylinder 2 to drive it to rotate, so that the screw feed cylinder 2 can be accurately aligned with different support 7 to meet the needs of adding different auxiliary materials.
[0051] Working principle:
[0052] The first step involves connecting the first stepper motor 4, the second stepper motor 12, the laser emitter 15, the photosensitive sensor 16, and the third motor 19 to the PLC control system. Different auxiliary materials are added to the three storage bins 6 on the base 1. During use, the first stepper motor 4 starts and drives the spiral feeding rod 3 to rotate through the bevel gear set 5. After the third motor 19 starts, it drives the spiral feeding cylinder 2 to rotate through the spur gear set 21, so that the feed hole of the spiral feeding cylinder 2 can be aligned with different support seats 7. After the support seats 7 open, the auxiliary materials can enter the spiral feeding cylinder 2. The rotating spiral feeding rod 3 will discharge the entered auxiliary materials along the opening at the end of the spiral feeding cylinder 2 towards the steelmaking furnace to complete the addition. The third motor 19 starts and drives the spiral feeding cylinder 2 to rotate through the spur gear set 21, which can make the feed hole of the spiral feeding cylinder 2 aligned with different support seats 7, so that various auxiliary materials can be added without moving the device.
[0053] In the second step, after the opening of the spiral feed cylinder 2 is aligned with the support 7, the second stepper motor 12 starts to drive the pull tube 13 to rotate clockwise. Figure 4(View angle) When the pull tube 13 rotates clockwise, it will pull the upper pull rod 11 to slide the insert plate 9 to the right, and at the same time, it will push the lower insert plate 9 to slide to the left via the lower pull rod 11. The upper insert plate 9 sliding to the right will cause the opening at the top of the quartz tube 8 to open, and the lower insert plate 9 sliding to the left will cause the opening at the bottom of the quartz tube 8 to close. After the top of the support 7 opens, the auxiliary material in the storage bucket 6 will enter the quartz tube 8 along the top of the quartz tube 8. The light emitted by the laser emitter 15 will pass through the quartz tube 8 and be directed to the photosensitive sensor 16. The photosensitive sensor 16 will determine that the light emitted by the laser emitter 15 has not reached the specified quantity when it receives the light emitted by the laser emitter 15. When the auxiliary material in the quartz tube 8 accumulates to the required height, the auxiliary material in the quartz tube 8 will block the light emitted by the laser emitter 15. After the photosensitive sensor 16 no longer receives the light emitted by the laser emitter 15, When the material quantity reaches the standard, the second stepper motor 12 drives the pull tube 13 to rotate counterclockwise. The pull tube 13 will cause the two insert plates 9 to reset. At this time, the top end of the quartz tube 8 will be closed and the bottom end of the quartz tube 8 will be opened. At this time, the auxiliary material in the storage bucket 6 will no longer enter the quartz tube 8. At the same time, the auxiliary material in the quartz tube 8 will enter through the opening of the spiral feeding cylinder 2. The rotating spiral feeding rod 3 will send the auxiliary material into the steelmaking furnace. Since the threaded rod 17 is threadedly connected to the collar 14, rotating the threaded rod 17 can cause the collar 14 to slide, and the height of the collar 14 can be slid to control the quantity of auxiliary material. The laser emitter 15 automatically adjusts the position of the two insert plates 9 and controls the opening and closing of the openings at both ends of the quartz tube 8, thereby reducing labor intensity and labor costs.
[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
