Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, and more specifically, to a smelting furnace slag cleaning device. Background Technology

[0002] A smelting furnace is a device that melts metal ingots and some scrap metals and adds necessary alloying components. After slag removal, refining and other operations, it melts them into the required alloy. After the smelting furnace is used, some residue will adhere to the inner wall of the furnace. At this time, it is necessary to pour in refining agent to reduce the adhesion of the residue, and then scrape off the slag with shovels and iron rods.

[0003] The existing publicly available technology, application number CN202221964877.9, describes a slag cleaning device for industrial residue smelting. This device, through a cleaning mechanism, activates a motor. The motor, via a T-shaped rod, drives an L-shaped telescopic sleeve rod to rotate, causing a side scraper to scrape the area around the inner wall of the smelting furnace, thus dislodging the slag adhering to it. Similarly, a collection box scrapes the bottom of the inner wall of the smelting furnace, pushing the slag accumulated therein into the collection box. This process effectively collects the slag, increasing the efficiency of cleaning the furnace's inner wall while reducing the workload of workers.

[0004] However, the above-mentioned patent still has certain drawbacks in use: the side scraper structure used for cleaning and slag removal has a fixed size, and the types of smelting furnaces it can be adapted to are relatively limited. It cannot well meet the needs of smelting furnaces of different sizes, thus limiting the scope of application of the structure, reducing its practicality, and the overall use effect is not ideal, leaving room for improvement.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a slag cleaning device for smelting furnaces, which has the advantages of wide applicability, convenient adjustment, and strong practicality, thereby solving the problems mentioned in the background technology.

[0007] To achieve the aforementioned advantages of wide applicability, convenient adjustment, and strong practicality, the specific technical solution adopted by this utility model is as follows: A slag cleaning device for a smelting furnace includes a movable platform and a rotating disk. A fixed arm is welded to the middle of the top of the movable platform. An adjusting arm is slidably connected to the inside of the fixed arm. A movable arm is welded to the top of the adjusting arm. A fixed plate is welded to the top of one side surface of the movable arm. A motor is installed on one side of the top of the fixed plate. The output end of the motor passes through one side of the fixed plate and is connected to the rotating disk. Several sets of adjusting grooves are evenly opened at the bottom of the rotating disk. A movable seat is slidably connected to the inside of the adjusting groove. A base plate is welded to the bottom of the movable seat. An extension plate is installed at the bottom of the base plate.

[0008] Furthermore, both the bottom of the base plate and the bottom of the expansion plate are provided with mating grooves.

[0009] Furthermore, a mating strip is installed at the top of the expansion plate.

[0010] Furthermore, scrapers are installed on the sides of both the base plate and the expansion plate.

[0011] Furthermore, positioning holes are provided on the surfaces of the fixed arm, the adjusting arm, the rotating disk, the moving seat, the base plate, and the extension plate, and the positioning holes are fixed by fasteners.

[0012] Furthermore, several sets of lockable casters are symmetrically installed on both sides of the bottom of the mobile platform.

[0013] Furthermore, the rotating disk has a circular structure.

[0014] Furthermore, the docking groove has the same structure as the docking strip.

[0015] Compared with the prior art, the present invention provides a slag cleaning device for smelting furnaces, which has the following beneficial effects: This invention utilizes a base plate and extension plate that can be spliced ​​and expanded to adjust the length of the entire cleaning component, thus adapting to smelting furnaces of different depths. Furthermore, by adjusting the spacing of the moving base, the spacing between multiple sets of plates can be changed, allowing for use with smelting furnaces of different inner diameters. The combined use of these two components effectively expands the overall applicability of the device, facilitating better operation. After structural adjustments are completed, the device can be easily moved to the side of the smelting furnace via the moving platform. Adjusting the adjusting arm allows the scraper to insert into the furnace and conform to the inner wall. Subsequently, the motor drives the scraper to scrape and remove the slag inside. The overall structure is flexible and adjustable, expanding the effective range without requiring excessive manual operation, reducing the intensity of use. It boasts advantages such as wide applicability, convenient adjustment, and high practicality. Attached Figure Description

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a slag cleaning device for a smelting furnace is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a slag cleaning device for a smelting furnace according to an embodiment of the present invention includes a movable platform 1 and a rotating disk 9. A fixed arm 2 is welded to the middle of the top of the movable platform 1. An adjusting arm 3 is slidably connected to the inside of the fixed arm 2. A movable arm 4 is welded to the top of the adjusting arm 3. A fixed plate 5 is welded to the top of one side of the movable arm 4. A motor 7 is installed on one side of the top of the fixed plate 5. The output end of the motor 7 passes through one side of the fixed plate 5 and is connected to the rotating disk 9. Several sets of adjusting grooves 6 are evenly opened at the bottom of the rotating disk 9. A movable seat 8 is slidably connected to the inside of the adjusting groove 6. A base plate 11 is welded to the bottom of the movable seat 8. An extension plate 15 is installed at the bottom of the base plate 11. A fixed arm 4 is welded to the middle of the top of the movable platform 1. Arm 2, the fixed arm 2 is made of vertical steel, and the welding surface adopts a full welding process to ensure that there is no bending deformation when bearing the cleaning components and slag impact. The fixed arm 2 serves as the sliding base for the adjusting arm 3, and its inner wall is polished to reduce the frictional resistance when the adjusting arm 3 slides. The welding position of the fixed arm 2 and the moving platform 1 is located near the center line of the moving platform 1, which, in conjunction with the weight distribution of the subsequent cleaning components, avoids the device tilting due to force on one side. The rigid connection between the moving platform 1 and the fixed arm 2 bears the total weight of the motor 7, the rotating disk 9, and the cleaning components, ensuring no significant deflection when the scraper 12 scrapes slag, and ensuring the stability of the cleaning operation. The adjusting arm 3 is inserted into the fixed arm 2 to form a sliding connection. The adjusting arm 3 can slide up and down along the inner wall of the fixed arm 2 to achieve high-speed adjustment of the cleaning components. The adjustable arm 3 and the fixed arm 2 are both equipped with positioning holes 10. When the adjustable arm 3 slides to the target height and the scraper 12 can be inserted into the furnace, the adjustable arm 3 and the fixed arm 2 are fixed by fasteners, such as bolts, through the aligned positioning holes 10 to prevent the adjustable arm 3 from sliding down during operation. The top of the adjustable arm 3 is welded with a moving arm 4, which is a horizontal steel arm. The welding direction is perpendicular to the adjustable arm 3 and consistent with the opening direction of the furnace to ensure that the subsequent cleaning components can be aligned with the center of the furnace. The top of the side of the moving arm 4 away from the adjustable arm 3 is welded with a fixing plate 5, which is a rectangular steel plate with threaded holes for installing the motor 7. The positioning holes 10 of the fixed arm 2 and the adjustable arm 3 are evenly distributed along the height direction with appropriate spacing. With common smelting furnace depths, the positioning holes 10 align when the adjusting arm 3 slides, ensuring that the scraper 12 can accurately fit the furnace wall after being inserted into the furnace, with no missed areas. The welding of the moving arm 4 to the adjusting arm 3 and the fixed plate 5 to the moving arm 4 are all full welds, ensuring that when the motor 7 drives the rotating disk 9, the power transmission is lossless and there is no loosening of the welding points. There is no vibration or deviation when the scraper 12 rotates to scrape slag. The height adjustment of the adjusting arm 3 can adapt to smelting furnaces of different depths, such as from small laboratory furnaces to large industrial furnaces, solving the problem of "single-adaptability" of traditional fixed height devices. The horizontal extension design of the moving arm 4 allows the cleaning components to cross the edge of the smelting furnace, avoiding collision between the main body of the device and the furnace body, while ensuring that the scraper 12 can cover the entire circumference of the furnace wall, reducing cleaning dead corners.

[0022] like Figure 1 and Figure 2 As shown, both the bottom of the base plate 11 and the bottom of the extension plate 15 are provided with mating grooves 14. The bottom of the base plate 11 is provided with mating grooves 14, and the top of the extension plate 15 is welded with mating strips 13. The mating grooves 14 and mating strips 13 have the same structure, both being rectangular or T-shaped. The extension plate 15 can be spliced ​​by inserting the mating strips 13 into the mating grooves 14 of the base plate 11. If the melting furnace is deep, mating grooves 14 can be opened at the bottom of the extension plate 15, and multiple sets of extension plates 15 can be stacked. After splicing, the positioning holes 10 on the surfaces of the base plate 11 and the extension plate 15 are aligned and fixed with fasteners to ensure that there is no looseness at the splice.

[0023] like Figure 1 and Figure 2 As shown, a connecting strip 13 is installed at the top of the expansion plate 15. The connecting groove 14 has the same structure as the connecting strip 13, ensuring that multiple sets of expansion plates 15 can be spliced ​​indefinitely, as long as the furnace depth allows. After splicing, the cleaning assembly is vertical and without bending, and the scraper 12 can always keep in contact with the furnace wall to scrape slag continuously. The splicing design of the expansion plate 15 can adjust the total height of the cleaning assembly according to the depth of the smelting furnace, adapting to different types such as shallow furnaces and deep furnaces, solving the problem of traditional fixed-length scrapers 12 being "unreachable in deep furnaces and wasted in shallow furnaces".

[0024] like Figure 1 and Figure 2 As shown, scrapers 12 are installed on the sides of the base plate 11 and the expansion plate 15. Scrapers 12 are welded to the sides of both the base plate 11 and the expansion plate 15. The scrapers 12 are made of arc-shaped wear-resistant steel plates with an arc that matches the inner wall of the smelting furnace. The welding surface is fully welded, and the edges of the scrapers 12 are quenched to improve wear resistance and prevent edge wear caused by long-term slag scraping. The arc design of the scrapers 12 is consistent with the arc of the furnace wall, which avoids excessive local pressure that scratches the furnace wall or insufficient pressure that fails to scrape off slag. The wear-resistant scrapers 12 work in conjunction with the rotating power to quickly remove slag adhering to the furnace wall. Moreover, the scrapers 12 can be replaced individually after wear, without replacing the entire cleaning assembly, thus reducing maintenance costs.

[0025] like Figure 1-4As shown, positioning holes 10 are provided on the surfaces of the fixed arm 2, adjusting arm 3, rotating disk 9, moving seat 8, base plate 11, and extension plate 15. These positioning holes 10 are fixed by fasteners. The positioning holes 10 are typically circular through holes, evenly spaced (usually 50-100mm) to accommodate different adjustment needs. The fasteners are high-strength bolts or pins that can be inserted into the aligned positioning holes 10 to lock the adjusted components in place. After the height of the adjusting arm 3 is adjusted, the fixed arm 2 and the adjusting arm 3 are... Align the positioning holes 10 of the arm 3 and insert fasteners to lock the height; after the spacing of the movable seat 8 is adjusted, align the rotating disk 9 with the positioning holes 10 of the movable seat 8 and insert fasteners to lock the spacing; after the extension plate 15 is spliced, align the base plate 11 with the positioning holes 10 of the extension plate 15 and insert fasteners to lock the splicing joint; ensure adjustment stability: the positioning holes 10 and fasteners cooperate to fix the adjustment position of each component, avoiding position displacement due to vibration during operation, such as the adjustment arm 3 sliding down or the movable seat 8 shifting, ensuring slag scraping accuracy; improve operation convenience: no complicated tools are required, only the fasteners need to be inserted and removed to complete the adjustment and locking, which improves the adjustment efficiency compared to the traditional welding and fixing device.

[0026] like Figure 1 As shown, several sets of lockable casters 16 are symmetrically installed on both sides of the bottom of the mobile platform 1. The mobile platform 1 serves as the core of the entire device, and several sets of lockable casters 16 are symmetrically installed on both sides of its bottom. The casters are fastened to the pre-set threaded holes on the bottom of the mobile platform 1 by bolts. The wheel body is made of wear-resistant rubber and has a built-in foot-operated brake lock. When unlocked, the device can move freely on the workshop floor to adapt to different smelting furnaces. When locked, the lock plate fits tightly with the wheel body to ensure that the device does not shift during cleaning operations, avoiding incomplete cleaning or scratching of the furnace wall due to shaking when the scraper 12 scrapes slag. The lockable casters 16 are rectangularly distributed, usually in 4 sets, located at the four corners of the bottom of the mobile platform 1, to ensure that the force is evenly distributed and there is no jamming when the device moves. After the brake lock is locked, the friction between the wheel body and the ground increases, resisting the reaction force generated when the scraper 12 rotates. The lockable casters 16 get rid of the site restrictions of traditional fixed cleaning devices, and the device can be quickly transferred between multiple smelting furnaces to meet the needs of alternating cleaning of multiple furnaces in the workshop and improve equipment utilization.

[0027] like Figure 1 and Figure 3As shown, the rotating disk 9 has a circular structure. The motor 7 is fixed to the top of the fixed plate 5 by bolts. The output end of the motor 7 passes through the fixed plate 5, and a bearing is installed at the passage to reduce rotational resistance. It is welded and fixed to the center of the rotating disk 9. The rotating disk 9 is a circular steel plate with several sets of adjustment grooves 6 evenly opened along the circumference of the bottom. The adjustment grooves 6 are rectangular through grooves with polished walls, allowing the movable seats 8 to slide. The movable seats 8 are rectangular steel blocks that are embedded in the adjustment grooves 6 to form a sliding connection. The movable seats 8 can slide radially along the adjustment grooves 6 to change the spacing between multiple sets of movable seats 8. A base plate 11 is welded to the bottom of the movable seats 8. The base plate 11 is a vertical steel plate that serves as the splicing base for the extension plate 15 and the mounting carrier for the scraper 12. The rectangular structure of the adjustment grooves 6 limits... The movable seat 8 slides only radially without circumferential offset, ensuring that when multiple sets of movable seats 8 are adjusted synchronously, the base plate 11 is always radially distributed and adapted to the circular inner wall of the smelting furnace, and the scraper 12 can evenly cover the furnace wall; the motor 7 drives the rotating disk 9 to rotate, and the speed can be adjusted by the speed regulator, driving the base plate 11, the extension plate 15 and the scraper 12 to rotate synchronously. The friction generated by the scraper 12 against the furnace wall scrapes off the slag, replacing the manual scraping of slag with a shovel and reducing labor intensity; the movable seat 8 slides along the adjustment groove 6, which can change the circumferential distance between the scrapers 12 to adapt to smelting furnaces with different inner diameters. For example, the distance between the movable seats 8 can be reduced for a furnace body with an inner diameter of 1m, and the distance can be increased for a furnace body with an inner diameter of 2m, ensuring that the scraper 12 can always be in contact with the furnace wall.

[0028] like Figure 1 and Figure 2 As shown, the docking groove 14 and the docking strip 13 have the same structure. Adaptation and adjustment: According to the inner diameter of the smelting furnace, adjust the spacing of the sliding moving seat 8, and fix it with fasteners after aligning the positioning holes 10; According to the furnace depth, insert the extension plate 15 into the docking groove 14 of the base plate 11 through the docking strip 13, and fix it after aligning the positioning holes 10, forming a suitable cleaning assembly; Movement and alignment: Unlock the lockable moving wheel 16, push the device to the side of the smelting furnace, and lock the wheel; Slide the adjusting arm 3 to allow the scraper 12 to extend into the furnace and fit against the furnace wall, and fix the adjusting arm 3 after aligning the positioning holes 10; Rotation and slag scraping: Start the motor 7, the rotating disk 9 drives the scraper 12 to rotate, and the scraper 12 scrapes the slag along the furnace wall. The scraped slag is discharged through the slag discharge port of the furnace body; Reset and transfer: After cleaning, turn off the motor 7, loosen the fastener of the adjusting arm 3, lift the adjusting arm 3 to make the scraper 12 disengage from the furnace body, unlock the wheels and transfer the device to the next furnace body; Wide range of applications: The movable seat 8 can be adjusted to accommodate different inner diameters, and the extension plate 15 can be spliced ​​to accommodate different depths, covering multiple types of industrial smelting furnaces; Convenient adjustment: The entire process is adjusted by sliding + locking through the positioning hole 10, without disassembly or welding, and can be operated by a single person; High practicality: The movable design is suitable for multi-furnace operation, the wear-resistant scraper 12 + stable power ensures efficient slag scraping, low maintenance cost, and is suitable for long-term industrial use.

[0029] Working principle: In actual use, personnel can select an appropriate number of extension plates 15 according to the size of the smelting furnace that needs slag cleaning. Then, the extension plates 15 are connected to each other and to the base plate 11 through the mating groove 14 and the mating strip 13, and then tightened with bolts to improve the connection strength between the structures and ensure the strength and stability of the use. Then, by sliding the movable seat 8, the spacing between multiple sets of base plates 11 can be changed to adapt to smelting furnaces with different inner diameters. After the structure is adjusted, it can be moved by locking casters. The mobile platform 1 is moved to the side of the smelting furnace where slag cleaning is required. Then, by adjusting the up and down movement of the adjusting arm 3, the base plate 11 and the extension plate 15 can be inserted into the smelting furnace, and the scrapers 12 on their surfaces can contact the inner wall of the smelting furnace. Then, the operation of the motor 7 can drive the rotating disk 9 to rotate, so that the scrapers 12 rotate inside the smelting furnace, thereby removing the slag attached to the inside. The removed slag can be discharged through the slag discharge port of the smelting furnace. The device as a whole has the advantages of wide applicability, convenient adjustment and strong practicality.
