Description

Technical Field

[0001] This invention relates to the field of converter metallurgy technology, and more specifically, to a raw material feeding device based on a metallurgical converter. Background Technology

[0002] In the process of converter smelting, various bulk metallurgical converter raw materials (including iron ore, coke, limestone and other metallurgical converter raw materials) need to be added to the converter through raw material feeding equipment. The feeding process usually involves using a conveying device to transport the bulk metallurgical converter raw materials directly from the silo to the discharge port at the end of the conveying device, and then introducing them into the converter through the raw material feeding equipment.

[0003] Currently, many raw material feeding devices on the market suffer from the following technical problems during use: Existing raw material feeding equipment often adds large quantities of ground and pulverized metallurgical converter raw materials directly into the converter at once. This results in uneven distribution of the raw materials within the converter, with some materials failing to fully participate in the reaction. Consequently, this wastes raw materials and reduces the efficiency of the entire metallurgical process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a raw material feeding device for metallurgical converters that enables intermittent discharge throughout the entire process, avoiding large-scale discharge at once. This prevents the raw materials from undergoing sufficient metallurgical reactions within the converter. Intermittent discharge not only avoids the large-scale addition of raw materials at once but also ensures uniform distribution of raw materials within the converter, thereby improving the efficiency of the metallurgical reaction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A raw material feeding device based on a metallurgical converter includes an installation assembly mounted on the metallurgical converter, on which a feeding assembly is slidably fitted.

[0011] The present invention is further configured such that: a top plate is fixed to each of the two outer sides of the storage box near the top, a support column is fixed to the bottom of each of the two top plates, and a limit nut is threadedly fitted to the bottom of each of the two support columns.

[0012] The bottom of the discharge cylinder is fixed with a discharge hopper, and two symmetrical extension plates are fixed on the outer periphery of the discharge hopper. The bottom of both extension plates is provided with sliding holes that are slidably fitted onto the support column.

[0013] The present invention is further configured such that: the mounting assembly includes a mounting base plate, a T-shaped base plate is fixed to the top of the mounting base plate, two symmetrical columns are fixed to the top of the T-shaped base plate, a mounting side plate is fixed to the side of the T-shaped base plate, a drive motor is fixed to the side of the mounting side plate, a lead screw is fixed to the output shaft of the drive motor, a rectangular groove is provided through the top of the T-shaped base plate, a hinge seat that is threadedly connected to the lead screw is slidably disposed inside the rectangular groove, a lifting arm is hingedly fitted inside the hinge seat, and a pin hole is provided through the side of the lifting arm.

[0014] The top of the T-shaped slide plate has guide holes that slide and fit on the two columns respectively. The side of the T-shaped slide plate has a rotating groove, and the inner wall of the rotating groove has a pin that rotates and fits with the pin hole.

[0015] The present invention is further configured such that: a support plate is fixed on one outer side of the storage box, a rotating rod is rotatably coupled to the support plate through a bearing, a main gear is fixed on the top of the rotating rod, a lever is fixed on the bottom of the rotating rod, and a second lever is fixed on the bottom of the lever.

[0016] The outer side of the storage box is connected to a guide cylinder extending into the interior of the storage box, located below the support plate. A transverse guide rod is slidably fitted inside the guide cylinder.

[0017] The invention is further configured such that: a contact ball is fixed at the end of the transverse guide rod inside the storage box; a side baffle is fixed at the end of the transverse guide rod outside the storage box; a sliding horizontal plate is fixed at the top of the side baffle; a swing groove is provided through the top of the sliding horizontal plate to slide with the second lever; and a second spring is fixed between the side baffle and the storage box.

[0018] The present invention is further configured such that: a conical guide body is fixed at the top of the discharge cylinder inside the storage box and in contact with the contact ball; a second slide cylinder is fixed at the top of the conical guide body and slidably fitted on the first slide cylinder; an extension hole extending into the discharge cylinder is provided through the bottom of the second slide cylinder; and the extension hole is slidably fitted with the guide rod.

[0019] The present invention is further configured such that a limiting ring is fixed near the top of the inner wall of the feed hopper.

[0020] The anti-stacking component includes two symmetrical semi-circular rotating rings. Each of the two semi-circular rotating rings has a connecting lug fixed to its end. The two connecting lugs are fixedly connected by bolts. Each of the two semi-circular rotating rings has an annular limiting groove on its outer wall that rotates and engages with a limiting ring. Each of the two semi-circular rotating rings has a semi-circular gear ring fixed to its top that meshes with the main gear. Each of the two semi-circular rotating rings has an extension plate fixed to its inner wall. Each of the two extension plates has an anti-stacking agitator that extends into the storage tank fixed to its bottom.

[0021] The advantages of this invention are: 1. By sliding the discharge cylinder up and down inside the guide cylinder, the discharge ports that are opened through the circumference of the discharge cylinder repeatedly leak out and close from the guide cylinder. This allows the metallurgical converter raw materials temporarily stored inside the storage box to be discharged intermittently from the discharge ports and finally enter the metallurgical converter through the discharge cylinder. This achieves an intermittent discharge process throughout the entire process, avoiding a large-scale discharge at once, which would result in an excessive amount of metallurgical converter raw materials being discharged, preventing them from undergoing sufficient metallurgical reaction inside the metallurgical converter. The intermittent discharge process not only avoids the large-scale addition of metallurgical converter raw materials at once, but also ensures the uniform distribution of metallurgical converter raw materials inside the converter, thereby improving the efficiency of the metallurgical reaction.

[0022] 2. In this invention, several sliding balls repeatedly slide and contact the surface of a conical column, causing the first spring, which is fixedly connected between the circular plate and the inclined support, to be repeatedly compressed. Combined with the elastic force of the first spring, this causes the anti-blocking cones fixed at the other ends of several sliding rods to reciprocate and clear the obstruction inside the several inclined supports set above several discharge ports. This prevents the raw materials of the metallurgical converter from clogging inside the discharge ports during intermittent discharge, thus preventing them from affecting the subsequent intermittent discharge process and improving the metallurgical efficiency of the metallurgical converter.

[0023] 3. This invention utilizes the reciprocating sliding of the swing groove on the circumferential side of the second lever to drive the lever plate fixed at the top of the second lever to reciprocate within a certain angle range. This allows the rotating rod to swing back and forth at a certain angle on the support plate, ultimately driving the main gear fixed at the top of the rotating rod to reciprocate back and forth. This causes the two semi-circular gear rings meshing with the gear to reciprocate back and forth on the limiting ring, thereby driving the entire anti-stacking component to reciprocate forward and reverse inside the storage box. This prevents the metallurgical converter raw materials entering the storage box from accumulating excessively in a certain area of ​​the storage box, ensuring that the metallurgical converter raw materials are evenly distributed inside the storage box, avoiding any impact on the subsequent discharge process, and improving the metallurgical efficiency of the entire process.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0042] Example 1, please refer to Figure 1-13 The present invention provides the following technical solutions: A raw material feeding device based on a metallurgical converter, specifically, includes an installation assembly 1 mounted on the metallurgical converter, with a feeding assembly 2 slidably fitted on the installation assembly 1; the feeding assembly 2 includes a storage component 3, a guide component 4 slidably fitted inside the storage component 3, and an anti-stacking component 5 rotatably fitted inside the storage component 3; the storage component 3 includes a storage box 301, a guide cylinder 302 connected to the bottom of the storage box 301, a feed hopper 303 fixed to the top of the storage box 301, a horizontal plate 304 fixed to the inner wall of the feed hopper 303 near the bottom, a guide rod 305 fixed to the center of the bottom of the horizontal plate 304, and a first sliding cylinder 306 fixed to the center of the bottom of the horizontal plate 304. A conical column 307 is fixed at the bottom; the guide component 4 includes a discharge cylinder 401 that is slidably fitted inside the guide cylinder 302. Several discharge ports 402 are opened through the periphery of the discharge cylinder 401. Several inclined supports 403 are fixed on the inner wall of the discharge cylinder 401 above the discharge ports 402. Sliding rods 404 are slidably fitted through the interior of each of the inclined supports 403. A circular plate 405 is fixed at one end of the sliding rod 404. A sliding ball 406 that slidably fits with the conical column 307 is fixed at the end of the circular plate 405. A first spring 407 that is sleeved and fitted between the circular plate 405 and the inclined supports 403 is fixed on the periphery of the sliding rod 404. An anti-blocking cone 408 is fixed at the other end of each of the sliding rods 404.

[0043] The specific application of this embodiment is as follows: During the metallurgical operation in the metallurgical converter, the raw materials for the metallurgical converter are first crushed by a grinding and pulverizing device. The crushed raw materials are then transported from the feed hopper 303 into the storage bin 301 for storage via a raw material conveying device (the grinding and pulverizing device and the raw material conveying device are existing technologies and are not shown in the figure, so they will not be elaborated on here). After the raw materials enter the storage bin 301, they are initially dispersed and evenly spread inside the storage bin 301. Subsequently, the discharge cylinder 401 slides up and down inside the guide cylinder 302, causing the several openings that penetrate the circumference of the discharge cylinder 401 to be... The dry discharge port 402 repeatedly leaks from and closes through the guide cylinder 302, allowing the metallurgical converter raw materials temporarily stored inside the storage box 301 to be intermittently discharged from several discharge ports 402 and finally enter the interior of the metallurgical converter through the discharge cylinder 401. This achieves intermittent discharge throughout the process, avoiding a large-scale discharge at once, which would result in an excessive amount of raw material being discharged, preventing the metallurgical converter raw materials from undergoing sufficient metallurgical reactions inside the converter. The intermittent discharge throughout the process not only avoids the large-scale addition of metallurgical converter raw materials at once but also ensures the uniform distribution of metallurgical converter raw materials within the converter, thereby improving the efficiency of the metallurgical reaction. During the intermittent discharge process, as the discharge cylinder 401 slides up and down inside the guide cylinder 302, several sliding balls 406 repeatedly slide and contact the surface of the conical column 307, causing the first spring 407, which is fixedly connected between the circular plate 405 and the inclined support 403, to be repeatedly compressed. Combined with the elastic force of the first spring 407, this causes the anti-blocking cones 408, which are respectively fixed at the other end of several sliding rods 404, to reciprocate and clear the obstruction inside the several inclined supports 403 set above several discharge ports 402. This prevents the raw materials of the metallurgical converter from clogging inside the several discharge ports 402 during the intermittent discharge, thus preventing them from affecting the subsequent intermittent discharge process and improving the metallurgical efficiency of the metallurgical converter.

[0044] Example 2, please refer to Figure 1-13This second embodiment is an improvement on the first embodiment. Specifically, a transverse plate 409 is fixed to the outer periphery of the discharge cylinder 401 below several discharge ports 402, and a transverse groove 410 is formed through the side of the transverse plate 409; a T-shaped slide plate 308 is fixed to one outer side of the storage box 301, and an L-shaped side plate 309 extending downward is fixed to the bottom of the T-shaped slide plate 308. A servo motor 310 is fixed to the inner wall of the L-shaped side plate 309, and a rotating arm 3 is fixed to the output shaft of the servo motor. 11. A first lever 312, which slides within the transverse groove 410, is fixed to the side of the rotating arm 311; a top plate 313 is fixed to both outer sides of the storage box 301 near the top, and a support column 314 is fixed to the bottom of both top plates 313, with a limit nut 315 threadedly fitted to the bottom of both support columns 314; a discharge hopper 411 is fixed to the bottom of the discharge cylinder 401, and two symmetrical extension plates 412 are fixed to the outer periphery of the discharge hopper 411, with the bottom of both extension plates 412... A sliding hole 413 is provided through the support column 314 for sliding engagement; the mounting assembly 1 includes a mounting base plate 101, a T-shaped base plate 102 is fixed to the top of the mounting base plate 101, two symmetrical columns 103 are fixed to the top of the T-shaped base plate 102, a mounting side plate 104 is fixed to the side of the T-shaped base plate 102, a drive motor 105 is fixed to the side of the mounting side plate 104, a lead screw 106 is fixed to the output shaft of the drive motor 105, and a rectangular groove is provided through the top of the T-shaped base plate 102. 107. A hinge seat 108 is slidably connected to the lead screw 106 inside the rectangular groove 107. A lifting arm 109 is hinged inside the hinge seat 108. A pin hole 110 is opened through the side of the lifting arm 109. A guide hole 316 is opened through the top of the T-shaped slide plate 308 and is slidably engaged with the two columns 103 respectively. A rotating groove 317 is opened on the side of the T-shaped slide plate 308. A pin 318 is fixed on the inner wall of the rotating groove 317 and is rotatably engaged with the pin hole 110.

[0045] The specific application of this embodiment 2 is as follows: Before metallurgical operation, when the entire equipment is installed and positioned at the feed inlet of the metallurgical converter, the drive motor 105 is started, which drives the lead screw 106 fixed to the output shaft of the drive motor 105 to rotate, so that the hinge seat 108 moves linearly inside the rectangular groove 107, which drives the lifting arm 109, which is hinged between the hinge seat 108 and the pin 318, to rotate downwards. This causes the two guide holes 316 through the top of the T-shaped slide plate 308 to move vertically on the two columns 103, which in turn drives the storage box 301 to move downwards synchronously, and causes the discharge cylinder 401, which is slidably fitted inside the guide cylinder 302, to move downwards synchronously. Finally, the bottom end of the discharge cylinder 401 is moved to a position close to the feed inlet of the metallurgical converter for the subsequent feeding process. During the feeding process, the servo motor 310 fixed to the inner wall of the L-shaped side plate 309 is activated, which drives the rotating arm 311 fixed to the output shaft of the servo motor 310 to rotate. This causes the first lever 312 fixed to the side of the rotating arm 311 to slide inside the transverse groove 410, thereby driving the transverse plate 409 to move up and down reciprocally in the vertical direction. This provides power for the intermittent discharge process in the metallurgical process, so that the raw materials of the metallurgical converter can enter the metallurgical converter intermittently during metallurgical operations, thus avoiding its impact on the subsequent metallurgical process.

[0046] Example 3, please refer to Figure 1-13 This third embodiment is an improvement on the first embodiment as follows: Specifically, a support plate 319 is fixed to one outer side of the storage box 301. A rotating rod 320 is rotatably fitted onto the support plate 319 via a bearing. A main gear 321 is fixed to the top of the rotating rod 320, and a lever 322 is fixed to the bottom of the rotating rod 320. A second lever 323 is fixed to the bottom of the lever 322. A guide cross cylinder 32 extending into the interior of the storage box 301 is connected through one outer side of the storage box 301 below the support plate 319. 4. A transverse guide rod 325 is slidably fitted inside the guide cylinder 324; a contact ball 326 is fixed at the end of the transverse guide rod 325 inside the storage box 301, and a side baffle 327 is fixed at the end of the transverse guide rod 325 outside the storage box 301. A sliding cross plate 328 is fixed at the top of the side baffle 327, and a swing groove 329 is provided through the top of the sliding cross plate 328 to slide with the second lever 323. A second spring 330 is fixed between the side baffle 327 and the storage box 301; discharge cylinder 40 1. A conical guide body 414 is fixed inside the storage bin 301 at the top, in contact with the contact ball 326. A second slide cylinder 415 is fixed at the top of the conical guide body 414 and slidably fitted on the first slide cylinder 306. An extension hole 416 extending into the discharge cylinder 401 is opened through the bottom of the second slide cylinder 415. The extension hole 416 is slidably fitted with the guide rod 305. A limit ring 331 is fixed near the top of the inner wall of the feed hopper 303. The anti-stacking component 5 includes two symmetrical semi-circular rotating rings 501. Each of the two semicircular rotating rings 501 has a connecting ear plate 502 fixed at its end. The two connecting ear plates 502 are fixedly connected by bolts. The outer walls of the two semicircular rotating rings 501 are provided with annular limiting grooves 503 that rotate and engage with the limiting rings 331. The tops of the two semicircular rotating rings 501 are fixed with semicircular gear rings 504 that mesh with the main gear 321. The inner walls of the two semicircular rotating rings 501 are fixed with extension plates 505. The bottoms of the two extension plates 505 are fixed with anti-stacking agitators 506 that extend into the storage bin 301.

[0047] The specific application of this embodiment three is as follows: When this equipment intermittently feeds raw materials to a metallurgical converter, the reciprocating up-and-down sliding of the discharge cylinder 401 inside the guide cylinder 302 drives the conical guide body 414 fixed at the top of the discharge cylinder 401 to reciprocate up-and-down sliding inside the storage box 301. When the conical guide body 414 reciprocates up-and-down sliding inside the storage box 301, it combines with the elastic force of the second spring 330 fixedly connected between the side baffle 327 and the storage box 301 to... The contact ball 326, which is in contact with the surface of the tapered guide 414, reciprocates inside the storage box 301, causing the transverse guide rod 325 to reciprocate horizontally inside the guide cylinder 324. (When the transverse guide rod 325 reciprocates horizontally inside the guide cylinder 324, two symmetrical rectangular limiting rails are fixed to its circumferential side, and two rectangular limiting grooves are opened on the inner wall of the guide cylinder 324, which respectively slide and engage with the two rectangular limiting rails, preventing horizontal movement.) When the guide rod 325 moves horizontally back and forth inside the guide cylinder 324, its transverse guide rod 325 rotates circumferentially, thereby causing the swing groove 329 through the top of the sliding plate 328 to slide on the circumferential side of the second lever 323. This causes the lever plate 322 fixed to the top of the second lever 323 to swing within a certain angle range, allowing the rotating rod 320 to swing back and forth on the support plate 319 at a certain angle, ultimately causing the lever plate 322 fixed to the top of the rotating rod 320 to swing back and forth on the support plate 319. The fixed main gear 321 reciprocates, causing the two semi-circular gear rings 504 meshing with it to reciprocate on the limiting ring 331. This drives the entire anti-stacking component 5 to reciprocate in both directions inside the storage box 301, preventing the metallurgical converter raw materials entering the storage box 301 from accumulating excessively in a certain area of ​​the storage box 301. This ensures that the metallurgical converter raw materials are evenly distributed inside the storage box 301, avoiding any impact on the subsequent discharge process and improving the overall metallurgical efficiency.
