Description

Technical Field

[0001] The present invention relates to the technical field of anhydrous taphole mud slicing, in particular to a mud slicing device and a slicing method for producing anhydrous taphole mud. Background Art

[0002] Anhydrous taphole clay is a key refractory material used to seal the tapholes of ironmaking blast furnaces. Its performance directly impacts blast furnace safety and operational efficiency. Compared to aqueous taphole clay, anhydrous taphole clay offers advantages such as high-temperature resistance, corrosion resistance, and excellent volume stability, making it particularly suitable for the intensified smelting needs of large blast furnaces. After production, most anhydrous taphole clay requires slicing to facilitate storage and sale. Slicing anhydrous taphole clay requires a slicing device.

[0003] Chinese patent CN217777258U discloses a taphole mud slicer for blast furnace anhydrous taphole mud. The slicer comprises a conveying assembly for conveying the anhydrous taphole mud, an extrusion assembly for extruding the anhydrous taphole mud, and a cutting assembly for cutting the anhydrous taphole mud. This utility model stirs the taphole mud before cutting, resulting in uniform texture and high-quality cut taphole mud. The utility model can cut taphole mud of varying lengths, offering wide applicability. Furthermore, the cut taphole mud is driven by a drive assembly, which moves the cutting blade along the length of the mounting platform, pushing the cut taphole mud out of a guide groove, thereby preserving the quality of the subsequently extruded taphole mud.

[0004] The above technical solution drives the extrusion head toward the extrusion port through the No. 1 electric cylinder to extrude the waterless cannon clay. After the waterless cannon clay is extruded to the required length, the No. 2 electric cylinder drives the cutting knife to move downward to cut the waterless cannon clay. This method causes the spiral blade to be unable to feed the material into the extrusion barrel when the extrusion head is extruding the waterless cannon clay, thereby causing an idle period in the extrusion equipment. When the length of the waterless cannon clay to be cut is longer, it means that the idle period of the spiral blade will also be longer. This method will greatly reduce the batch slicing of the waterless cannon clay. In addition, when the cutting knife in the above technical solution cuts the freshly extruded waterless cannon clay, due to the high viscosity of the waterless cannon clay at this time, some of the waterless cannon clay will stick to the cutting knife, resulting in material waste.

[0020] S2, driving the speed change gear to move by the electric push rod, thereby replacing the speed change gear that drives the reciprocating drive assembly, thereby changing the speed of the reciprocating drive assembly, and thus reducing the speed of the up and down reciprocating movement of the cutter;

[0021] S3. The reciprocating drive assembly is driven by a driving motor to operate, thereby driving the cutter to move up and down through the reciprocating drive assembly to slice the extruded anhydrous taphole mud. When the reciprocating drive assembly drives the cutter to move upward, the scraper removes the anhydrous taphole mud adhering to the surface of the cutter, and the nozzle 52 blows off the anhydrous taphole mud on the scraper. Then the conveyor belt transports the sliced ​​anhydrous taphole mud.

[0022] Compared with the prior art, the present invention provides a mud slicing device and a slicing method for producing anhydrous taphole mud, which have the following beneficial effects:

[0023] 1. The present invention, when slicing the anhydrous cannon mud, drives the speed gear to rotate by the driving motor, and the speed gear rotates to drive the reciprocating drive assembly to operate, and the reciprocating drive assembly operates to drive the cutter to move back and forth up and down, and then the anhydrous cannon mud is extruded by the extrusion mechanism. At this time, the cutter slices the extruded anhydrous cannon mud, and the cut anhydrous cannon mud falls onto the conveyor belt and is transported away by the conveyor belt. When the slice length needs to be adjusted, the speed gear is driven to move by the electric push rod, thereby replacing the speed gear that drives the reciprocating drive assembly to operate. The speed of the reciprocating drive component slows down, and the frequency of the up and down movement of the cutter becomes lower. At this time, since the movement stroke of the cutter remains unchanged and the extrusion speed of the extrusion mechanism remains unchanged, the frequency of the movement of the cutter is reduced, so that the length of the waterless cannon mud extruded by the extrusion mechanism cut by the cutter becomes longer, thereby realizing the adjustment of the cutting length, and when slicing the waterless cannon mud, there will be no long idle time, thereby avoiding the problem of a long idle period in the extrusion mechanism due to the adjustment of the slicing length of the waterless cannon mud, thereby reducing the slicing efficiency of the waterless cannon mud.

[0024] 2. In the present invention, when the reciprocating drive assembly drives the cutter to move downward, the linkage assembly drives the scraper and the nozzle to flip 90 degrees. At this time, the scraper is separated from the cutter. At this time, the nozzle blows air to the scraper, thereby blowing the anhydrous cannon mud attached to the scraper onto the conveyor belt, thereby realizing the collection of the anhydrous cannon mud. When the cutter completes cutting and moves upward, the linkage assembly drives the scraper and the nozzle to flip to the original position. At this time, the scraper contacts the surface of the cutter. At this time, as the cutter moves upward, the scraper scrapes off the anhydrous cannon mud attached to the surface of the cutter, and the nozzle can blow air to the connection between the scraper and the cutter, thereby blowing the anhydrous cannon mud scraped off by the scraper onto the conveyor belt, which is convenient for subsequent collection and greatly reduces the probability of anhydrous cannon mud adhering to the scraper.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] As introduced in the background technology, in order to solve the deficiencies in the prior art and the above technical problems, this application proposes a mud slicing device and a slicing method for the production of waterless cannon mud.

[0039] Example 1: Please refer to Figures 1-11 , the mud slicing device includes an extrusion mechanism 1, a gantry 2 and a conveyor belt 3. The center lines of the extrusion mechanism 1, the gantry 2 and the conveyor belt 3 are on the same horizontal line. The extrusion mechanism 1 is used to extrude the anhydrous taphole mud, and the conveyor belt 3 is used to transport the sliced ​​anhydrous taphole mud;

[0040] The gantry 2 is provided with a slicing mechanism 4 and a cleaning mechanism 5. The slicing mechanism 4 includes a drive motor 41, an electric push rod 42, a reciprocating drive assembly 43 and a cutter 44. A plurality of speed change gears 45 with a gradually increasing number of outer ring teeth are horizontally arranged on the output shaft of the drive motor 41. The drive motor 41 is used to drive the reciprocating drive assembly 43 to operate. The electric push rod 42 is used to adjust the position of the speed change gear 45. The reciprocating drive assembly 43 is used to drive the cutter 44 to move back and forth. The speed change gear 45 is used to adjust the speed of the reciprocating drive assembly 43.

[0041] The cleaning mechanism 5 includes a scraper 51, a nozzle 52 and a linkage assembly 53. The scraper 51 is used to scrape the surface of the cutter 44, the nozzle 52 is used to clean the surface of the scraper 51, and the linkage assembly 53 is used to drive the scraper 51 and the nozzle 52 to rotate.

[0042] When the reciprocating drive assembly 43 drives the cutter 44 to move upward, the scraper 51 can remove the anhydrous taphole mud attached to the outside of the cutter 44, and the nozzle 52 can blow air to the connection between the scraper 51 and the cutter 44.

[0043] During use, the speed change gear 45 is driven to rotate by the driving motor 41, and the speed change gear 45 rotates to drive the reciprocating drive assembly 43 to operate. The reciprocating drive assembly 43 operates to drive the cutter 44 to move back and forth along the gantry 2, and then the waterless taphole mud is extruded through the extrusion mechanism 1. At this time, the cutter 44 cuts the extruded waterless taphole mud, and the cut waterless taphole mud falls onto the conveyor belt 3. At this time, the conveyor belt 3 transports the cut waterless taphole mud. When the cutting length of the waterless taphole mud needs to be adjusted, the speed change gear 45 is driven to move by the electric push rod 42, thereby replacing the speed change gear 45 that drives the reciprocating drive assembly 43 to operate, and then adjusting the speed of the reciprocating drive assembly 43. At this time, the frequency of the up and down movement of the cutter 44 becomes lower. At this time, since the movement stroke of the cutter 44 remains unchanged and the extrusion speed of the extrusion mechanism 1 remains unchanged, the frequency of the movement of the cutter 44 is reduced, so that the length of the waterless taphole mud cut by the cutter 44 by the extrusion mechanism 1 becomes longer, thereby realizing the adjustment of the cutting length.

[0044] When the reciprocating drive assembly 43 drives the cutter 44 to move downward, the linkage assembly 53 drives the scraper 51 and the nozzle 52 to flip 90 degrees. At this time, the scraper 51 is separated from the cutter 44. At this time, the nozzle 52 blows air to the scraper 51, thereby blowing the anhydrous cannon mud attached to the scraper 51 onto the conveyor belt 3, thereby collecting the anhydrous cannon mud. When the cutter 44 completes the cutting of the anhydrous cannon mud and moves upward, the linkage assembly 53 drives the scraper 51 and the nozzle 52 to flip to their original position. At this time, the scraper 51 contacts the surface of the cutter 44. Since the position of the scraper 51 is fixed, as the cutter 44 moves upward, the scraper 51 scrapes off the anhydrous cannon mud attached to the surface of the cutter 44, and the nozzle 52 blows air to the connection between the scraper 51 and the cutter 44, so that the anhydrous cannon mud scraped off by the scraper 51 is blown onto the conveyor belt 3, which is convenient for subsequent collection and can also reduce the probability of the anhydrous cannon mud adhering to the scraper 51, thereby achieving the ability to slice the anhydrous cannon mud while greatly reducing the idle period when adjusting the cutting length of the anhydrous cannon mud, thereby avoiding the problem of affecting the efficiency of slicing the anhydrous cannon mud, and can also clean the surface of the cutter 44, thereby avoiding the problem of anhydrous cannon mud adhering to the cutter 44.

[0045] Example 2: See Figures 1-11, which is different from the above-mentioned embodiment 1, the extrusion mechanism 1 includes an extruder housing 11 and an extrusion motor 12. A feed port 13 is provided on the top of the extruder housing 11, and a control box 14 is provided on the outside of the extruder housing 11. The control box 14 is used to control the opening and closing of the extrusion motor 12, the drive motor 41 and the electric push rod 42. A step plate is fixedly connected to the bottom of the extruder housing 11. The control box 14, the gantry 2 and the conveyor belt 3 are all arranged on the step plate. A worm gear reducer 15 is provided on the output shaft of the extrusion motor 12, and a screw rod is connected to the inner side of the worm gear reducer 15. 16, the screw rod 16 is distributed inside the extruder housing 11, and the extruder housing 11 is also provided with an extrusion port 111. A transmission gear 17 is fixedly connected to the screw rod 16, and a fixed gear 18 is fixedly connected to the outside of the transmission gear 17. The fixed gear 18 is rotatably connected to the extruder housing 11 through a bearing seat. A stirring gear 19 is meshed with the outside of the fixed gear 18. The stirring gears 19 are distributed on both sides of the screw rod 16, and the stirring gears 19 are meshed with each other. A stirring shaft 110 is fixedly connected to the stirring gear 19, and the stirring shaft 110 is distributed inside the extruder housing 11;

[0046] During use, the extrusion motor 12 is controlled to operate, and the operation of the extrusion motor 12 drives the worm gear reducer 15 to rotate. The rotation of the worm gear reducer 15 drives the screw rod 16 to rotate. The rotation of the screw rod 16 drives the transmission gear 17 to rotate. The rotation of the transmission gear 17 drives the fixed gear 18 to rotate. The rotation of the fixed gear 18 drives the stirring shaft 110 in the extruder housing 11 to rotate. At this time, the user pours the anhydrous cannon mud into the feed port 13 on the extruder housing 11. At this time, the anhydrous cannon mud enters the extruder housing 11. At this time, the stirring shaft 110 in the extruder housing 11 stirs and stretches the anhydrous cannon mud, thereby improving the subsequent molding quality of the anhydrous cannon mud. After that, the anhydrous cannon mud falls to the bottom of the extruder housing 11 under the action of gravity. At this time, the screw rod 16 stirs and transports the anhydrous cannon mud, and then extrude it through the extrusion port 111.

[0047] Example 3, see Figures 1-11, which is different from the above-mentioned embodiment 2, is that a key slot 411 is provided on the inner side of the output shaft of the driving motor 41, a key shaft 412 is inserted into the inner side of the key slot 411, and the speed change gear 45 is fixedly connected to the key shaft 412, and a mounting plate 413 is provided on the end of the key shaft 412 away from the key slot 411. The key shaft 412 is mounted on the mounting plate 413 through a bearing, and the output shaft of the electric push rod 42 is fixedly connected to the mounting plate 413. The gantry 2 is fixedly connected to the fixed plate 21, and the driving motor 41 and the electric push rod 42 are both fixedly connected to the fixed plate 21. The reciprocating drive assembly 43 includes a transmission shaft 431 and a limiting groove 432. The transmission shaft 431 is rotatably connected to the gantry 2 through a bearing seat, and the end of the transmission shaft 431 away from the gantry 2 is fixedly connected to the driving gear 433. The gear 433 is meshed with the speed change gear 45. A cam 434 is fixedly connected to the transmission shaft 431. The cam 434 is distributed between the driving gear 433 and the gantry 2. A limiting groove 432 is provided on the gantry 2, and the limiting grooves 432 are distributed on both sides of the gantry 2. The inner side of the limiting groove 432 is fixedly connected to a limiting rod 435. A slide 436 is slidably connected to the limiting rod 435. The slide 436 is provided with an arc groove 437. The arc groove 437 and the cam 434 are distributed on the same vertical line. The cutter 44 is fixedly connected to the bottom of the slide 436. The bottom of the slide 436 is also fixedly connected to a return spring 438. The return spring 438 is distributed inside the limiting groove 432, and the end of the return spring 438 away from the slide 436 is fixedly connected to the inside of the limiting groove 432.

[0048] When in use, the control driving motor 41 is operated, the driving motor 41 is operated to drive the key slot 411 to rotate, the key slot 411 is rotated to drive the key shaft 412 to rotate, the key shaft 412 is rotated to drive the speed change gear 45 to rotate, the speed change gear 45 is rotated to drive the driving gear 433 to rotate, the driving gear 433 is rotated to drive the cam 434 to rotate through the transmission shaft 431, and the cam 434 is rotated and contacts the circular arc groove 437 on the slide plate 436, and squeezes the circular arc groove 437 under the action of the rotational force, at this time the slide plate 436 moves down along the limit rod 435 under the cooperation of the cam 434 and the circular arc groove 437, and the slide plate 436 moves down to squeeze The return spring 438 is pressed, the slide plate 436 moves down and drives the cutter 44 to move down. The cutter 44 moves down to cut the waterless taphole mud extruded by the extrusion mechanism 1, and then the cam 434 separates from the arc groove 437. At this time, the slide plate 436 returns to its original position under the action of the elastic force of the return spring 438. At this time, the cutter 44 follows the slide plate 436 to move up, thereby returning to its original position. Then the cam 434 rotates again until it contacts the arc groove 437. Similarly, the cam 434 forces the slide plate 436 and the cutter 44 to move down. At this time, the cutter 44 cuts the waterless taphole mud again. Then the cam 434 separates from the slide plate 436 again. At this time, the cutter 44 is in the reset position. Under the action of spring 438, it returns to its original position again. At this time, with the continuous rotation of cam 434, slide plate 436 and cutter 44 move back and forth, thereby slicing the waterless cannon mud. When the cutting length of the waterless cannon mud needs to be adjusted, the user drives the mounting plate 413 to move through the electric push rod 42. The movement of the mounting plate 413 drives the key shaft 412 and the speed change gear 45 to move toward the drive motor 41. At this time, the key shaft 412 gradually penetrates into the key groove 411, and the original speed change gear 45 is separated from the driving gear 433. After that, the other speed change gear 45 on the key shaft 412 moves to a position meshing with the driving gear 433. The gear 433 is rotated at this time, and the speed change gear 45 drives the driving gear 433 to rotate. Since the number of teeth of the speed change gear 45 is reduced at this time, as the driving motor 41 is running, the speed change gear 45 rotates, the speed of the driving gear 433 is reduced, and the speed of the cam 434 is reduced. As a result, the frequency of movement of the slide 436 and the cutter 44 is reduced. Since the movement stroke of the cutter 44 remains unchanged and the extrusion speed of the extrusion mechanism 1 remains unchanged, the frequency of movement of the cutter 44 is reduced, which will make the cut length of the waterless taphole mud extruded by the extrusion mechanism 1 longer, and the cutter 44 can cut the waterless taphole mud, thereby realizing the adjustment of the cutting length.

[0049] Example 4, see Figures 1-11, different from the above-mentioned embodiment 3, the linkage assembly 53 includes a rack 531, the rack 531 is fixedly connected to the slide 436, and the racks 531 are distributed on both sides of the slide 436, the outer side of the rack 531 is meshed with a cleaning gear 532, and the cleaning gear 532 is fixedly connected to a rotating shaft 533, which is distributed on the inner side of the gantry 2, and the two ends of the rotating shaft 533 extend out of the gantry 2 respectively, and both ends of the rotating shaft 533 are rotatably connected to the gantry 2, the scraper 51 is fixedly connected to the rotating shaft 533, and the nozzles 52 are distributed in an array on the scraper 51, and the outer side of the nozzle 52 is fixedly connected to a spring tube 521, and the end of the spring tube 521 away from the nozzle 52 is fixedly connected to a connecting pipe 522, and the connecting pipe 522 has an electric valve built in. The end of the connecting pipe 522 away from the spring tube 521 is fixedly connected to an air pump 523, and the air pump 523 is fixedly connected to the top surface of the gantry 2;

[0050] When in use, start the air pump 523, and the air pump 523 works to deliver compressed air to the nozzle 52 through the connecting pipe 522 and the spring tube 521. When the reciprocating drive assembly 43 drives the cutter 44 to move downward, the slide plate 436 drives the rack 531 to move downward, and the rack 531 moves downward to drive the cleaning gear 532 to rotate. The rotation of the cleaning gear 532 drives the rotating shaft 533 to rotate in a circle. The rotation of the rotating shaft 533 drives the scraper 51 to rotate. The rotation of the scraper 51 drives the nozzle 52 to rotate, thereby turning the scraper 51 to an inclined state. In this process, the nozzle 52 continues to blow air to the surface of the scraper 51, thereby blowing a small amount of waterless cannon mud attached to the scraper 51 onto the conveyor belt 3 and onto the cutter 44. When the cutter 44 moves upward, the rack 531 drives the cleaning gear 532 to rotate in the opposite direction. Similarly, the scraper 51 and the nozzle 52 are flipped to their original positions. At this time, the scraper 51 contacts the cutter 44. Since the positions of the scraper 51 and the nozzle 52 are fixed relative to the cutter 44, when the cutter 44 moves upward, the scraper 51 can remove the anhydrous cannon mud adhering to the surface of the cutter 44, and the removed anhydrous cannon mud falls onto the conveyor belt 3 again. In this process, the nozzle 52 continuously blows air to the scraper 51, thereby blowing the anhydrous cannon mud scraped off by the scraper 51 onto the conveyor belt 3, thereby achieving cleaning of the cutter 44 while greatly reducing the risk of anhydrous cannon mud adhering to the scraper 51.

[0051] The slicing method for producing anhydrous taphole mud, using the above-mentioned mud slicing device, comprises the following steps:

[0052] S1, firstly extrude the anhydrous taphole mud through the extrusion mechanism 1;

[0053] S2. The electric push rod 42 is operated to drive the speed change gear 45 to move, thereby replacing the speed change gear 45 that drives the reciprocating drive assembly 43, thereby changing the speed of the reciprocating drive assembly 43, and thereby reducing the speed of the up and down reciprocating movement of the cutter 44;

[0054] S3. The reciprocating drive assembly 43 is driven by the drive motor 41 to operate, thereby driving the cutter 44 to move up and down through the reciprocating drive assembly 43 to slice the extruded anhydrous taphole mud.
