Description

Technical Field

[0001] This invention relates to the field of slag cleaning technology for melting furnaces, and more particularly to a slag cleaning device for melting furnaces. Background Technology

[0002] A melting furnace is an industrial device used to heat and melt metals or alloys. The melting furnace is responsible for heating metal raw materials such as aluminum ingots to a molten state, providing molten metal liquid for subsequent casting processes. This is the first step in manufacturing blanks for components such as cylinder heads.

[0003] Under high temperature conditions, the slag is in a molten or semi-molten state and will gradually seep into the micropores and cracks on the surface of the furnace wall refractory material. After cooling, the slag and refractory material are tightly bonded together to form a strong composite. If manual cleaning is carried out by swinging a hammer or prying with a steel chisel, the force will be dispersed and it will be difficult to apply force accurately. In addition, the operation will be inefficient, time-consuming and labor-intensive, and the operators will also face high safety risks. Summary of the Invention

[0042] 3.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] This embodiment relates to a slag cleaning device for a melting furnace, see reference. Figures 1 to 9 As shown, the system includes a support 1, with connecting parts at both ends for bolting to the melting furnace. The connecting parts include a slide 7, a connecting frame 8, a first threaded hole 9, a second threaded hole 10, a third threaded hole 11, a connecting plate 12, a fourth threaded hole 13, a connecting groove 14, and a fifth threaded hole 15. Each of the first threaded hole 9, second threaded hole 10, third threaded hole 11, fourth threaded hole 13, and fifth threaded hole 15 is fitted with corresponding bolts and nuts. The components are configured as follows:

[0056] The slide groove 7 is located on both sides of the support 1. The connecting frame 8 is slidably installed in the slide groove 7. The connecting frame 8 is a hollow rectangular plate structure with one end open. The first threaded hole 9 is opened on the inner wall of the slide groove 7 and penetrates the side wall of the support 1. There are at least 6 first threaded holes 9. The second threaded hole 10 is opened on one end of the connecting frame 8 located in the slide groove 7. The structure and position of the first threaded hole 9 correspond to the second threaded hole 10. The opening of the slide groove 7 enables the connecting frame 8 to have good position adjustment capability, allowing the connecting frame 8 to move along the slide groove 7 for a certain stroke. By adjusting the distance between the two connecting frames 8, it can be adapted to the width of different specifications of melting furnaces, thereby significantly improving the applicability of the device. After determining the appropriate position, the connecting frame 8 can be reliably fixed and limited in the slide groove 7 by using bolts and nuts with the first threaded hole 9 and the second threaded hole 10, which helps to ensure the stability of the device.

[0057] The third threaded hole 11 is provided on the connecting frame 8, and at least three third threaded holes 11 are provided. The connecting plate 12 is slidably installed in the connecting frame 8. The fourth threaded hole 13 is provided on the connecting plate 12. Through the sliding connection between the connecting frame 8 and the connecting plate 12, the connecting plate 12 can move along the connecting frame 8 for a certain stroke. By adjusting the distance between the support 1 and the melting furnace, the device can be adapted to melting furnaces of different specifications, which helps to improve the applicability of the device. After determining the appropriate position, the connecting plate 12 can be reliably fixed and limited in the connecting frame 8 by using bolts and nuts with the third threaded hole 11 and the fourth threaded hole 13, which helps to ensure the stability of the device.

[0058] The connecting groove 14 is opened on the end of the connecting plate 12 away from the fourth threaded hole 13, and the fifth threaded hole 15 is opened on the inner wall of the connecting groove 14 and penetrates the side wall of the connecting plate 12. It should be noted that a connecting rectangular block adapted to the connecting groove 14 is installed on the melting furnace by bolts, and the connecting rectangular block has a threaded hole corresponding to the fifth threaded hole 15.

[0059] The bracket 1 is equipped with an xy-axis moving platform 2, which consists of two sets of lead screw slides with different installation directions. The two lead screw slides are orthogonally arranged, with one lead screw slide installed along the x-axis and the other along the y-axis. It should be noted that the lead screw slides are equipped with telescopic dust covers.

[0060] A mounting frame 4, driven by an xy-axis moving platform 2, is installed on the bracket 1. A mounting block 5 is slidably mounted on the mounting frame 4. The mounting frame 4 is equipped with a drive unit for driving the mounting block 5. The telescopic component 3 has the same structure as the drive unit. The telescopic component 3, driven by the drive unit, is fixedly mounted on the mounting block 5. A motor 6 is detachably connected to the output end of the telescopic component 3. Both the motor 6 and the telescopic component 3 are industrial-grade equipment. In this embodiment, the specific models of the motor 6 and the telescopic component 3 are not limited, as long as they can operate in a working environment such as furnace slag cleaning. In this embodiment, the specific fixing method between the telescopic component 3 and the motor 6 is not limited, as long as they can be detachably connected. For example, the telescopic component 3 and the motor 6 can be connected by flange bolts or by key connection with locking nuts. The drive unit includes a mounting sleeve 16, a first electric cylinder 17, a push plate 18, a hydraulic plate 19, a telescopic push rod 20, and a buffer spring 21. The components are configured as follows:

[0061] Mounting sleeve 16 is fixedly mounted on mounting bracket 4. First electric cylinder 17 is fixedly mounted within mounting sleeve 16. Push plate 18 is fixedly connected to the output end of first electric cylinder 17. First electric cylinder 17 is equipped with a displacement sensor, which is used to monitor and precisely control its stroke in real time. The maximum value of this stroke needs to be adapted according to the actual specifications of the melting furnace cavity to ensure that the operating range of first electric cylinder 17 matches the size of the furnace cavity. Hydraulic plate 19 is slidably fitted within mounting sleeve 16. Hydraulic oil is filled between push plate 18 and hydraulic plate 19. Due to the incompressible nature of hydraulic oil and the damping effect generated during its flow, [the system achieves the desired effect]. It helps absorb and dissipate the impact and vibration generated during the progressive cutting process, and avoids reverse impact and cumulative damage to the first electric cylinder 17 during operation. The telescopic push rod 20 is fixedly connected to the hydraulic plate 19. The telescopic push rod 20 passes through and extends to the outside of the mounting sleeve 16. The telescopic push rod 20 is fixedly connected to the mounting block 5. The buffer spring 21 is fixedly connected between the hydraulic plate 19 and the mounting sleeve 16. The buffer spring 21 is movably fitted on the telescopic push rod 20. The buffer spring 21 further enhances the shock absorption and buffering performance of the hydraulic oil system through its elastic deformation, thereby forming a composite damping mechanism, which helps to improve the impact resistance of the drive unit.

[0062] The motor 6 is detachably connected to the progressive cutting section or bucket 30 via a flexible coupling. The progressive cutting section includes a connecting block 22, a dustproof cylinder 23, a second electric cylinder 24, a sealing plate 25, a connecting rod 26, a first cutting blade 27, a second cutting blade 28, and a third cutting blade 29. The components are arranged as follows:

[0063] Connecting block 22 is connected to the output end of motor 6 via a flexible coupling. The flexible coupling effectively compensates for axial, radial, and angular deviations between motor 6 and connecting block 22, while absorbing vibrations and impacts during operation, reducing the load on the bearings of motor 6, and helping to extend the service life of the equipment. Dustproof cylinder 23 is fixedly installed on connecting block 22, and second electric cylinder 24 is fixedly installed in dustproof cylinder 23. Sealing plate 25 is slidably installed in dustproof cylinder 23, and sealing plate 25 is fixedly connected to the output end of second electric cylinder 24. The sealing plate 25 and dustproof cylinder 23 create a relatively sealed installation environment for second electric cylinder 24. To effectively prevent dust intrusion, it should be noted that the dustproof cylinder 23 is made of copper. Utilizing copper's excellent thermal conductivity, it effectively dissipates heat from the second electric cylinder 24, improving both the dustproof and heat dissipation performance of the second electric cylinder 24. The connecting rod 26 is fixedly connected to the sealing plate 25, extending through and beyond the dustproof cylinder 23. The first cutting blade 27 is detachably connected to the connecting rod 26. The first cutting blade 27 is a grinding wheel structure. The grinding wheel has a certain degree of micro-elasticity and can undergo slight deformation under pressure. Therefore, the first cutting blade 27 can better conform to the curved and concave surfaces of the furnace wall. The pits and irregular contours can be smoothed and ground by a grinding wheel to produce a relatively flatter and more uniform furnace wall surface, providing a good foundation for the next melting. A pressure sensor is provided at the connection between the connecting rod 26 and the first cutting blade 27. The pressure sensor can directly sense the force on the working end of the first cutting blade 27 without intermediate structural losses, which helps to improve the dynamic response speed of the pressure sensor. This embodiment does not limit the specific model of the pressure sensor, but it is required to have high temperature resistance and support wireless signal transmission or slip ring power supply to meet the requirements of the working environment of the first cutting blade 27. The pressure sensor monitors the first cutting blade 27 in real time. 7. During operation, when the first cutting blade 27 encounters an exceptionally hard slag or protrusion, the pressure signal monitored by the pressure sensor will change dramatically. The second electric cylinder 24 will control the first cutting blade 27 to temporarily retract, which helps to prevent the first cutting blade 27 from chipping when it comes into contact with these exceptionally hard slag or protrusion. At this time, the first electric cylinder 17 will automatically reduce its operating speed to keep in sync with the grinding rhythm of the first cutting blade 27. The connecting block 22, the dustproof cylinder 23, the second electric cylinder 24, the sealing plate 25, and the connecting rod 26 together constitute a set of execution units. At least one set of execution units is provided.

[0064] The second cutting blade 28 is detachably connected to the connecting block 22. The outer edge of the second cutting blade 28 has an arc-shaped blade, thus generating a continuous cutting surface during rotation. This provides a stable scraping force and prevents excessive wedging that could cause jamming. The second cutting blade 28 has 3 to 6 chip removal grooves on the side near the first cutting blade 27 to guide away scraped slag, keeping the blade surface clean. The thickness of the second cutting blade 28 gradually increases from the inside to the outside on the side near the first cutting blade 27, which helps guide the scraped slag to the outside during rotation, preventing it from being scraped off during the first cutting blade 27. Accumulation occurs on the surface of the second cutting blade 28. The second cutting blade 28 has a clearance groove for avoiding the dustproof cylinder 23. The third cutting blade 29 is detachably connected to the second cutting blade 28. The outer edge of the third cutting blade 29 has a large wedge-shaped tooth structure. When the large wedge-shaped tooth structure contacts the slag, its sharp tip concentrates the impact force at a very small contact point, generating extremely high local pressure. This pressure instantly exceeds the slag's compressive strength and indents initial cracks at the slag's weak points. As the large wedge-shaped tooth structure further wedges in, the steep slopes on both sides apply strong lateral compressive force to the cracks, causing the material to... The tensile and shear deformation ultimately causes large pieces of slag to macroscopically fragment along their own crystal or structural defects. The diameter of the second cutting blade 28 is 1.3 times the diameter of the first cutting blade 27, and the diameter of the third cutting blade 29 is 1.3 times the diameter of the second cutting blade 28. Through the large diameter difference between the first cutting blade 27, the second cutting blade 28, and the third cutting blade 29, the scraping surface of the second cutting blade 28 can effectively cover the area broken by the third cutting blade 29, and a reasonable allowance is reserved for the fine finishing of the first cutting blade 27. It should be noted that the diameters of the first cutting blade 27, the second cutting blade 28, and the third cutting blade 29 are significantly different. All three cutting blades 29 are detachable, allowing for quick and individual replacement when the first cutting blade 27, second cutting blade 28, and third cutting blade 29 are worn or damaged. This helps reduce downtime and maintenance costs. In this embodiment, the specific installation method of the first cutting blade 27, second cutting blade 28, and third cutting blade 29 is not limited, as long as a detachable and fixed connection can be achieved. The first cutting blade 27, second cutting blade 28, and third cutting blade 29 together constitute a cutting assembly, and only one cutting assembly is provided.

[0065] In this embodiment, the position of the connecting frame 8 in the slide 7 is adjusted according to the specifications of the melting furnace. After the adjustment is completed, the connecting frame 8 is fixed in the slide 7 by bolts and nuts engaging the first threaded hole 9 and the second threaded hole 10. The position of the connecting plate 12 in the connecting frame 8 is adjusted. After the adjustment is completed, the connecting plate 12 is fixed in the connecting frame 8 by bolts and nuts engaging the third threaded hole 11 and the fourth threaded hole 13. Finally, the connecting rectangular block on the melting furnace is inserted into the connecting groove 14, and the connection between the device and the melting furnace is completed by bolts and nuts engaging the fifth threaded hole 15.

[0066] The xy-axis moving platform 2 and the telescopic component 3 are activated to adjust the spatial position of the progressive cutting section, allowing it to enter the furnace cavity. The motor 6 is then activated, causing the progressive cutting section to rotate. The xy-axis moving platform 2 drives the progressive cutting section to move and abut against the inner walls on both sides of the furnace cavity. At this time, the third cutting blade 29 first contacts the slag attached to the inner walls on both sides of the furnace cavity, and the second cutting blade 28 and the first cutting blade 27 then contact the slag attached to the inner walls on both sides of the furnace cavity in sequence. This avoids the need for manual intervention in the slag removal operation. During the process of the progressive cutting section cutting the slag attached to the inner walls on both sides of the furnace cavity, the cutting stroke is adjusted by the first electric cylinder 17 to ensure the integrity of slag removal.

[0067] When the first cutting blade 27 encounters an exceptionally hard slag or protrusion, the pressure signal monitored by the pressure sensor at the connection between the connecting rod 26 and the first cutting blade 27 will change dramatically. The second electric cylinder 24 will control the first cutting blade 27 to temporarily retract, which helps to prevent the first cutting blade 27 from chipping when it comes into contact with these exceptionally hard slag or protrusions. At this time, the first electric cylinder 17 will automatically reduce its operating speed to keep in sync with the grinding rhythm of the first cutting blade 27.

[0068] After the inner walls on both sides of the furnace cavity are completely cleaned, the progressive cutting part is removed from the output end of the motor 6. Then, the bucket 30 is installed on the output end of the motor 6 through the flexible coupling. Finally, the spatial position of the bucket 30 is controlled by the xy axis moving platform 2 and the telescopic component 3, so as to complete the removal of slag in the furnace cavity through the bucket 30.

[0069] 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.
