Description

Technical Field

[0001] This invention relates to the field of casting, and more particularly to a device for cleaning iron bricks from steel ladles. Background Technology

[0002] Ladle bricks are key refractory materials used for lining steel ladles in the steel smelting process. In steel production, steel ladles play a vital role, as they must not only bear the high-temperature molten steel and be transferred, but also meet the requirements of refining and other processes. Ladle bricks are the core element that ensures that the steel ladle can successfully complete these tasks. After casting, the surface of the ladle bricks needs to be cleaned by a cleaning device.

[0003] A search revealed Chinese patent application CN223455090U, which discloses a cleaning device for permeable bricks in steel ladles. The device includes a gas supply mechanism, a conveying mechanism, a blowing mechanism, an adjusting mechanism, and a display mechanism. The display mechanism is fixedly connected to the conveying mechanism, the blowing mechanism is fixedly connected to the conveying mechanism, and the conveying mechanism is fixedly connected to the gas supply mechanism. The adjusting mechanism includes an adjusting seat, an adjusting ring, a vertical rod, and an adjusting inner cylinder. The adjusting inner cylinder, when rotated by the adjusting ring, can change the direction of gas delivery within the conveying mechanism, thus enabling the delivery of different gases within the same pipeline. This design is simple to operate and solves the problems of requiring separate gas delivery for oxygen and nitrogen, the numerous connecting pipes, and the inconvenience of use.

[0004] Existing equipment typically cleans steel ladle sheet bricks by spraying gas. However, some impurities adhere to the surface of the steel ladle sheet bricks, making it ineffective to remove them simply by spraying gas. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel-clad iron sheet brick cleaning device includes a base, with a left conveyor belt and a right conveyor belt arranged on the left and right sides of the base. Cleaning mechanisms are respectively arranged on the left and right conveyor belts. A flipping mechanism is arranged on the top of the base, located between the left and right conveyor belts. The cleaning mechanism includes two connecting seats, two connecting shafts, a sleeve, a hydraulic cylinder, and a cleaning component. The two connecting shafts are arranged on one side of the two connecting seats. The two sides of the sleeve are fixedly connected to the two connecting shafts. The hydraulic cylinder is fixed inside the sleeve and connected to the cleaning component. The flipping mechanism includes two side plates, a rotating shaft, two connecting plates, and a flipping motor. Support plates are connected between the two side plates and the base. The two ends of the rotating shaft are rotatably connected to the side plates. The flipping motor is connected to the rotating shaft. The two connecting plates are symmetrically fixed on both sides of the rotating shaft. A storage groove is opened on one side of the connecting plate.

[0007] Preferably, the cleaning assembly includes a support plate, a scraper, and a cleaning plate. The top of the support plate is connected to a hydraulic cylinder, the scraper is fixed to one side of the support plate, the top of the support plate has a chip discharge port, one side of the chip discharge port is inclined, and the cleaning plate is fixed to the bottom of the support plate and has bristles.

[0008] Preferably, the cleaning mechanism is provided with a swing mechanism on both sides. The swing mechanism includes a support shaft, two pulleys, a belt, a shaft, a drive wheel, a driven wheel, a connecting rod, a half gear, and a rack. The support shaft is connected to the conveyor belt, the shaft is rotatably connected to the connecting seat, the two pulleys are respectively fixed to the support shaft and the shaft and connected by the belt, the drive wheel is fixed to the shaft, the connecting rod is rotatably connected to the connecting seat, the driven wheel and the half gear are fixed to the connecting rod, the drive wheel meshes with the driven wheel, and the rack is fixed under the slider and meshes with the half gear.

[0009] Preferably, each of the two connecting seats has a sliding opening on one side, and a slider is slidably connected inside the sliding opening. The slider is fixed to one side of the connecting shaft, and a buffer spring is provided between the slider and the inner wall of the sliding opening.

[0010] Preferably, the bottom of the left and right conveyor belts is provided with a chip removal mechanism, which includes a base plate and multiple scrapers. The base plate is fixed on the base, and the multiple scrapers are fixed on the base plate at equal intervals.

[0011] Preferably, the scraper is inclined, and its inclination direction is opposite to the movement direction of the corresponding conveyor belt.

[0012] Preferably, one side of the base plate is sloped to facilitate the discharge of impurities from the base.

[0013] Preferably, a sensor is installed inside the storage slot, and a controller is installed on one side of the base. The controller is electrically connected to the flipping motor and the sensor.

[0014] Preferably, both the left and right conveyor belts include a conveyor frame, two rotating rollers, a connecting belt, and a drive motor. The conveyor frame is fixed on the base, the two rotating rollers are rotatably connected to both sides of the conveyor frame and connected by the connecting belt, and the drive motor is connected to one of the rotating rollers.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention, through the arrangement of a left conveyor belt, a right conveyor belt, a flipping mechanism, and a cleaning mechanism, cleans the cast ladle sheet bricks. The ladle sheet bricks are placed on the left conveyor belt, which transports their surface. When the bricks reach below the cleaning mechanism, the cleaning mechanism cleans them. A scraper removes impurities adhering to the bricks, which are then moved upwards and discharged through a chip outlet. Brushes clean the removed impurities. The cooperation between the scraper and brushes improves the cleaning effect on the ladle sheet bricks, preventing the ineffectiveness of air jet cleaning, which often results in poor cleaning. After processing, the left conveyor belt continues to move the steel-clad iron brick. At this time, one end of the steel-clad iron brick is inserted into the receiving slot by the action of the left conveyor belt. The sensor will detect the insertion of the steel-clad iron brick and transmit a signal. The flipping motor will drive the rotating shaft and connecting plate to rotate, thereby transporting the steel-clad iron brick on the left conveyor belt to the right conveyor belt, thus achieving the flipping process of the steel-clad iron brick. The right conveyor belt will transport the steel-clad iron brick to the bottom of the cleaning mechanism, so that the other side of the steel-clad iron brick can be cleaned by the cleaning mechanism. Through the cooperation between the left conveyor belt, the right conveyor belt, the two cleaning mechanisms and the flipping mechanism, both sides of the steel-clad iron brick can be effectively cleaned, improving the cleaning effect of the device on the steel-clad iron brick.

[0017] 2. This invention, through the arrangement of a left conveyor belt, a right conveyor belt, a cleaning mechanism, and a swing mechanism, allows the support shaft to rotate along with the left and right conveyor belts when conveying steel-clad iron bricks. At this time, the engagement between the two pulleys and the belt causes the shaft to drive the drive wheel to rotate. Simultaneously, the drive wheel meshes with the driven wheel, causing the connecting rod to rotate synchronously. The half-gear rotates synchronously with the connecting rod. When the half-gear meshes with the rack, the rack, under the action of the half-gear, drives the cleaning component to move in the opposite direction to the side where the steel-clad iron bricks are moving. This significantly enhances the shearing and peeling effect of the scraper on impurities, thereby effectively improving the scraping effect of the scraper on impurities. Attached Figure Description

[0026] Example 1, referring to Figures 1-6 A steel ladle sheet brick cleaning device includes a base 1, a left conveyor belt 6 and a right conveyor belt 3 arranged on the left and right sides of the base 1, and two cleaning mechanisms 5. The left conveyor belt 6 and the right conveyor belt 3 are both fixed to the base 1 by bolts. The two cleaning mechanisms 5 are respectively arranged on the left conveyor belt 6 and the right conveyor belt 3. The two cleaning mechanisms 5 are in the same position on the left conveyor belt 6 and the right conveyor belt 3, and are both close to the rear side, so that there is a relative distance between the position of the steel ladle sheet brick conveying and the cleaning mechanism 5, so as to ensure the cleaning effect of the cleaning mechanism 5 on both sides of the steel ladle sheet brick. A flipping mechanism 2 is provided on the top of the base 1. The flipping mechanism 2 is located between the right conveyor belt 3 and the left conveyor belt 6, and is used to flip the steel ladle sheet brick for cleaning.

[0027] The cleaning mechanism 5 includes two connecting seats 15, two connecting shafts 18, a sleeve 20, a hydraulic cylinder 19, and a cleaning component 21. The two connecting shafts 18 are disposed on one side of the two connecting seats 15. The two sides of the sleeve 20 are welded to the two connecting shafts 18. The hydraulic cylinder 19 is fixedly sleeved inside the sleeve 20 and is fixedly connected to the cleaning component 21.

[0028] The cleaning assembly 21 consists of a support plate 23, a scraper 25, and a cleaning plate 26. The top of the support plate 23 is bolted to the hydraulic cylinder 19. The scraper 25 is bolted to one side of the support plate 23. A chip discharge port 24 is provided through one side of the top of the support plate 23. One side of the chip discharge port 24 is inclined. The bottom of the support plate 23 is bolted to the cleaning plate 26. Multiple brush bristles 27 are evenly arranged at the bottom of the cleaning plate 26.

[0029] The flipping mechanism 2 includes two side plates 8, a rotating shaft 11, two connecting plates 12, and a flipping motor 10. The two side plates 8 are connected to the base 1 by bolts with support plates 9. The flipping motor 10 is fixed to one side of one of the side plates 8 by bolts. The two ends of the rotating shaft 11 are rotatably connected to the two side plates 8 by bearings. One side of the flipping motor 10 is fixedly connected to the rotating shaft 11. The two connecting plates 12 are symmetrically fixed on both sides of the outer circumference of the rotating shaft 11. A storage groove 13 is provided on one side of the two connecting plates 12. The bottom of the storage groove 13 is on the same plane as the top of the left conveyor belt 6 and the right conveyor belt 3, ensuring that the steel-clad iron bricks can be accurately inserted into the storage groove 13 during transportation. A sensor is installed inside the storage groove 13. A controller is connected to one side of the base 1 by bolts. The controller is electrically connected to the flipping motor 10.

[0030] The working process of the flipping mechanism 2: When cleaning the cast ladle sheet bricks, the ladle sheet bricks are placed on the left conveyor belt 6, which transports the surface of the ladle sheet bricks. When the ladle sheet bricks move to the bottom of the cleaning mechanism 5, the cleaning mechanism 5 cleans them. The scraper 25 scrapes off the impurities adhering to the ladle sheet bricks. The impurities move upward through the scraper 25 and are discharged through the chip discharge port 24. The brush 27 cleans the scraped impurities. The cooperation between the scraper 25 and the brush 27 improves the cleaning effect of the device on the ladle sheet bricks, preventing the ineffective cleaning of the ladle sheet bricks by air jets. The cleaning of the bricks resulted in poor cleaning of the steel-clad iron bricks. After cleaning, the left conveyor belt 6 continued to move the steel-clad iron bricks. At this time, one end of the steel-clad iron bricks was inserted into the storage slot 13 by the action of the left conveyor belt 6. The sensor detected the insertion of the steel-clad iron bricks and transmitted a signal. The flipping motor 10 then drove the rotating shaft 11 and the connecting plate 12 to rotate, thereby transporting the steel-clad iron bricks on the left conveyor belt 6 to the right conveyor belt 3, thus achieving the flipping process of the steel-clad iron bricks. The right conveyor belt 3 transported the steel-clad iron bricks to the bottom of the cleaning mechanism 5, so that the other side of the steel-clad iron bricks could be cleaned by the cleaning mechanism 5.

[0031] In this invention, both the right conveyor belt 3 and the left conveyor belt 6 include a conveyor frame, two rotating rollers, a connecting belt, and a drive motor for driving the rotating rollers to rotate. The conveyor frame is fixed to the base 1 by bolts. The two rotating rollers are rotatably connected to both sides of the conveyor frame by bearings. The two rotating rollers are rotatably connected to the connecting belt. One side of the conveyor frame is connected to the drive motor by bolts. One side of the drive motor is fixedly connected to one of the rotating rollers.

[0032] In this invention, in order to alleviate the impact of steel-clad iron bricks on the cleaning component 21 during transportation, a sliding opening 16 is provided through one side of each of the two connecting seats 15. A slider 17 is slidably connected to the inner wall of the sliding opening 16. The slider 17 is fixed to one side of the connecting shaft 18 by bolts. A buffer spring 22 is welded between one side of the slider 17 and the sliding opening 16.

[0033] In this invention, the impurities after the cleaning mechanism 5 cleans the steel ladle bricks will fall onto the left conveyor belt 6 and the right conveyor belt 3. In order to facilitate the cleaning of impurities, a chip removal mechanism is provided at the bottom of the left conveyor belt 6 and the right conveyor belt 3. The chip removal mechanism consists of a base plate 4 and multiple scrapers 14. The base plate 4 is fixed to the base 1 by bolts, and the multiple scrapers 14 are fixed at equal distances on the base plate 4. At the same time, in order to facilitate the discharge of impurities from the base 1, one side of the base plate 4 is set as an inclined surface. In order to improve the processing effect of the scrapers 14 on impurities, the scrapers 14 are inclined in the opposite direction to the direction of movement of the right conveyor belt 3 and the left conveyor belt 6.

[0034] Example 2, refer to Figures 1-7 A steel-clad iron brick cleaning device, compared with Embodiment 1, is provided with a swing mechanism 7 on both sides of the two cleaning mechanisms 5. The swing mechanism 7 cooperates with the right conveyor belt 3 and the left conveyor belt 6 to improve the cleaning effect of the cleaning mechanism 5 on the steel-clad iron brick.

[0035] Based on the above, the swing mechanism 7 includes a support shaft 28, two pulleys 29, a belt 30, a shaft 31, a drive wheel 32, a driven wheel 33, a connecting rod 34, a half gear 35, and a rack 36. The support shaft 28 is welded to one side of the right conveyor belt 3 or the left conveyor belt 6. The shaft 31 is rotatably connected to one side of the connecting seat 15 via a bearing. The two pulleys 29 are respectively fixedly sleeved on the support shaft 28 and the shaft 31, and the two pulleys 29 are rotatably connected to the belt 30. The drive wheel 32 is fixedly sleeved on the outer circumference of the shaft 31. One end of the connecting rod 34 is rotatably connected to the connecting seat 15 via a bearing. The driven wheel 33 and the half gear 35 are both fixed on the connecting rod 34. The drive wheel 32 and the driven wheel 33 mesh with each other. The rack 36 is fixed to the bottom of the slider 17 by bolts, and the half gear 35 meshes with the rack 36.

[0036] The working process of the swing mechanism 7: When conveying steel-clad iron bricks through the left conveyor belt 6 and the right conveyor belt 3, the support shaft 28 will rotate with the rotation of the left conveyor belt 6 and the right conveyor belt 3. At this time, the shaft 31 drives the drive wheel 32 to rotate through the cooperation between the two pulleys 29 and the belt 30. While the drive wheel 32 is rotating, it drives the driven wheel 33 to drive the connecting rod 34 to rotate synchronously through meshing. The half gear 35 will rotate synchronously with the rotation of the connecting rod 34. At this time, when the half gear 35 is rotating and meshing with the rack 36, the rack 36 will drive the cleaning component 21 to move in the opposite direction to the side where the steel-clad iron bricks are moving under the action of the half gear 35. At this time, the shearing force and peeling effect of the scraper 25 on the impurities are significantly enhanced, thereby effectively improving the scraping effect of the scraper 25 on the impurities.

[0037] In summary, with the help of the above-mentioned technical solution of the present invention: when cleaning the cast ladle sheet bricks, the ladle sheet bricks are placed on the left conveyor belt 6, and the surface of the ladle sheet bricks is conveyed by the left conveyor belt 6. When the ladle sheet bricks move to the bottom of the cleaning mechanism 5, the cleaning mechanism 5 cleans the ladle sheet bricks. The scraper 25 scrapes off the impurities adhering to the ladle sheet bricks. The impurities move upward by the scraper 25 and are discharged through the chip discharge port 24. The brush 27 cleans the scraped impurities. The cleaning process, through the cooperation between the scraper 25 and the brush 27, improves the cleaning effect of the ladle iron bricks, preventing the ineffective cleaning of the ladle iron bricks caused by air jets. After cleaning, the left conveyor belt 6 continues to move the ladle iron bricks. At this time, one end of the ladle iron brick will be inserted into the storage slot 13 under the action of the left conveyor belt 6. The sensor will detect the insertion of the ladle iron brick and transmit a signal, which will drive the rotating shaft through the flipping motor 10. The support shaft 28 rotates along with the connecting plate 12, thereby conveying the steel-clad iron bricks on the left conveyor belt 6 to the right conveyor belt 3, thus achieving the flipping of the steel-clad iron bricks. The right conveyor belt 3 then conveys the steel-clad iron bricks to the area below the cleaning mechanism 5, where the cleaning mechanism 5 cleans the other side of the steel-clad iron bricks. While the steel-clad iron bricks are being conveyed by the left and right conveyor belts 6 and 3, the support shaft 28 rotates along with them. At this time, the shaft is activated by the interaction between the two pulleys 29 and the belt 30. The rod 31 drives the drive wheel 32 to rotate, and the drive wheel 32, while rotating, meshes with the driven wheel 33 to drive the connecting rod 34 to rotate synchronously. The half gear 35 rotates synchronously with the connecting rod 34. At this time, when the half gear 35 meshes with the rack 36 while rotating, the rack 36, under the action of the half gear 35, drives the cleaning component 21 to move in the opposite direction to the side where the steel ladle iron brick is moving. At this time, the shearing force and peeling effect of the scraper 25 on the impurities are significantly enhanced, thereby effectively improving the scraping effect of the scraper 25 on the impurities.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
