Description

Technical Field

[0001] This invention pertains to slag removal technology for heat preservation furnaces, specifically an automatic slag removal mechanism for a lead-antimony alloy liquid heat preservation furnace. Background Technology

[0002] The current method for removing slag from lead-antimony alloy liquid holding furnace is as follows: First, open the furnace cover, sprinkle an appropriate amount of slag remover into the alloy liquid inside the holding furnace, and stir to fully mix the slag remover with the alloy liquid; then close the furnace cover and heat up to cause the oxides in the alloy liquid to float to the surface; after the reaction is complete, open the furnace cover again and use a strainer to remove the slag.

[0003] However, existing slag removal methods generally rely on manual operation, which is not only inefficient but also poses certain safety hazards. While some automatic slag removal equipment exists on the market with the development of automation technology, it is difficult to achieve efficient one-time slag removal in actual use, and it also lacks continuous heat preservation capabilities. As a result, some alloy liquid remains in the retrieved slag, making it difficult to recover and reuse, thus wasting resources.

[0004] Therefore, an automatic slag removal mechanism for a lead-antimony alloy liquid holding furnace with efficient slag removal and continuous heat preservation functions is designed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing devices that are not efficient enough in slag removal and do not have continuous heat preservation function, the technical problem is: to provide an automatic slag removal mechanism for a lead-antimony alloy liquid heat preservation furnace with efficient slag removal and continuous heat preservation function.

[0006] The technical solution of this invention is: an automatic slag removal mechanism for a lead-antimony alloy liquid holding furnace, comprising a base, a linear motor, a mounting base, a rotary drive device, and a scooping funnel. A linear motor is mounted on one side of the base, and a rotary drive device is mounted on the slider of the linear motor via the mounting base to drive the scooping funnel to flip and scoop slag inside the holding furnace. The scooping funnel is located at the power output end of the rotary drive device. The invention also includes a slag removal mechanism and a heat preservation structure. The slag removal mechanism is installed inside the scooping funnel for automatically scraping away any residue remaining inside the scooping funnel. The scum removal mechanism includes a push-pull frame, a scraper, a connecting shaft, a first cylinder, and an arc-shaped guide rail. The push-pull frame is axially slidably installed on the inner side of the retrieval funnel. A scraper is installed on one side of the push-pull frame and is in contact with the inner wall of the retrieval funnel. A connecting shaft is installed on the other side of the push-pull frame. A first cylinder is installed on the other side of the upper part of the mounting base. Arc-shaped guide rails are installed on the telescopic shaft ends of the first cylinder, and one end of the connecting shaft is movably sleeved in the guide groove of the arc-shaped guide rail. A heat insulation structure is also installed on the rotary drive device, and the heat insulation structure is located on the periphery of the retrieval funnel.

[0007] Furthermore, the rotation axis of the retrieval funnel is aligned with the central axis of the heat preservation furnace, so that when the retrieval funnel rotates, its rotation trajectory can completely cover the entire cross-section of the heat preservation furnace.

[0008] Furthermore, the insulation structure includes a connecting arm, an insulation frame, an insulation cover, and a limiting arm. A connecting arm is provided on one side of the upper part of the mounting base. The end of the connecting arm away from the mounting base is connected to the insulation frame. The insulation frame is arranged around the retrieval funnel, and the drive shaft rotates through the insulation frame. An opening and closing insulation cover is hinged to the upper side of the insulation frame. The limiting arm is located at the telescopic shaft end of the first cylinder and near the arc-shaped guide rail. An opening and a positioning groove are respectively opened on one side of the insulation frame and the insulation cover to engage with the limiting arm, which are used to lock the position of the insulation cover when scraping slag.

[0009] Furthermore, the rotary drive device includes a drive motor, drive teeth, driven teeth, and a transmission shaft. The drive motor is mounted on the upper part of the mounting base. The output shaft of the drive motor is connected to the drive teeth via a key. The transmission shaft is rotatably mounted on the connecting arm, and the retrieval funnel is connected to the output end of the transmission shaft. One end of the transmission shaft is connected to the driven teeth via a key, and the drive teeth mesh with the driven teeth to form a speed reduction transmission mechanism for driving the retrieval funnel to rotate and retrieve scum.

[0010] Furthermore, it also includes a collection box, a lower receiving frame, an upper receiving frame, and a filter screen. The collection box is located on the other side of the base, directly below the retrieval funnel. The collection box is equipped with a lower receiving frame and an upper receiving frame that can be pulled out and moved. The collection box contains a filter screen, which is located at the bottom of the upper receiving frame, for separating scum from molten alloy.

[0011] Furthermore, it also includes a lower receiving plate, an upper receiving plate, and a second cylinder. The lower receiving frame and the upper receiving frame are respectively connected to the outer side of the lower receiving frame and the upper receiving frame. The lower side of the lower receiving plate is in contact with the bottom of the collection box, and the lower side of the upper receiving plate is in contact with the surface of the filter screen. Two relatively staggered second cylinders are provided on the base, and the extension shafts of the two second cylinders are respectively connected to the lower receiving plate and the upper receiving plate.

[0012] Furthermore, the upper inner sides of the lower and upper receiving frames are respectively provided with slanted openings for guiding scum.

[0013] Furthermore, it also includes a servo motor, an adjusting arm, and a nozzle. A servo motor is installed on the front side of the insulation frame, and an adjusting arm is connected to the output shaft of the servo motor. A nozzle is connected to the adjusting arm and used to spray the slag-removing agent evenly into the insulation furnace through external pipelines.

[0014] The beneficial effects are as follows: By controlling the linear motor to move the retrieval funnel to the top of the holding furnace, the drive motor rotates the retrieval funnel 180 degrees through gear transmission, so that its opening cuts downward into the surface of the alloy liquid in the holding furnace for retrieval. This ensures that the rotation trajectory of the retrieval funnel can completely cover the cross-section of the furnace body, thereby achieving efficient and rapid removal of scum. Furthermore, during the retrieval process, the closing action of the insulation cover and insulation frame can seal and insulate the furnace opening and the retrieval funnel, effectively preventing the alloy liquid from solidifying and facilitating the rapid separation of the retrieved scum from the alloy liquid, thus improving the insulation sealing performance and the continuity of the operation.

Detailed Implementation

[0025] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Specific Embodiment 1: The present invention provides an automatic slag removal mechanism for a lead-antimony alloy liquid holding furnace, such as... Figures 1 to 5As shown, the device includes a base 1, a linear motor 2, a mounting base 3, a rotary drive device, a scooping funnel 7, a slag removal mechanism, and a heat preservation structure. A heat preservation furnace 100 and a linear motor 2 are integrated on the left and right sides of the base 1, respectively. A furnace cover 200 is hinged to the upper side of the heat preservation furnace 100, and a hydraulic cylinder 300 for automatic opening and closing is hinged to one side of the furnace cover 200. A mounting base 3 is mounted on the slider of the linear motor 2, and a rotary drive device is installed on the upper part of the mounting base 3 to drive the scooping funnel 7 to rotate and scoop slag from inside the heat preservation furnace 100. The retrieval funnel 7 is located at the power output end of the rotary drive device. A slag removal mechanism is installed inside the retrieval funnel 7 to automatically scrape away residual slag from the inside. The retrieval funnel 7 is a semi-circular tubular structure with perforations, and its rotation axis is aligned with the central axis of the holding furnace 100. When the retrieval funnel 7 rotates, its rotation trajectory completely covers the entire cross-section of the holding furnace 100. When the linear motor 2 drives the retrieval funnel 7 to move horizontally above the holding furnace 100, the rotary drive device drives the retrieval funnel 7 to automatically remove residual slag. The scooping funnel 7 rotates 180 degrees, causing its opening to cut downwards into the alloy liquid surface, thus completing the slag removal. Since the rotation trajectory of the scooping funnel 7 completely covers the entire cross-section of the holding furnace 100, it ensures comprehensive and efficient removal of the slag. The slag removal mechanism includes a push-pull frame 8, a scraper 9, a connecting shaft 12, a first cylinder 10, and an arc-shaped guide rail 11. The push-pull frame 8 is axially slidably mounted on the inner side of the scooping funnel 7. A scraper 9 is mounted on one side of the push-pull frame 8, and the scraper 9 is in contact with the inner wall of the scooping funnel 7. The other side of the push-pull frame 8 is... A connecting shaft 12 is provided, and a first cylinder 10 is provided on the other side of the upper part of the mounting base 3. The telescopic shaft end of the first cylinder 10 is respectively provided with an arc-shaped guide rail 11, and one end of the connecting shaft 12 is movably sleeved in the guide groove of the arc-shaped guide rail 11. The first cylinder 10 controls the connecting shaft 12, the push-pull bracket 8 and the scraper 9 to move back and forth synchronously, so that the scraper 9 automatically scrapes off the scum remaining on the inner wall of the retrieval funnel 7. The rotary drive device is also provided with a heat preservation structure, which is located on the periphery of the retrieval funnel 7 and is used to keep the retrieval funnel 7 warm during retrieval to prevent the alloy liquid from solidifying.

[0027] like Figures 1 to 5As shown, the insulation structure includes a connecting arm 5, an insulation frame 13, an insulation cover 14, and a limiting arm 15. The connecting arm 5 is provided on one side of the upper part of the mounting base 3. The end of the connecting arm 5 away from the mounting base 3 is connected to the insulation frame 13. The insulation frame 13 is arranged around the salvage funnel 7, and the drive shaft 6 rotatably passes through the insulation frame 13. The insulation cover 14, which can be opened and closed, is hinged to the upper side of the insulation frame 13. The limiting arm 15 is located at the telescopic shaft end of the first cylinder 10 and near the arc-shaped guide rail 11. The insulation frame 13 and the insulation cover 14 are respectively provided with an opening 130 and a positioning groove 140 that engage with the limiting arm 15, which are used to lock the position of the insulation cover 14 when scraping slag. The insulation structure, through the opening and closing design of the insulation frame 13 and the insulation cover 14, effectively prevents the alloy liquid from solidifying during the salvage process, ensuring the continuity and stability of the production process, and at the same time facilitating the subsequent cleaning and maintenance of the inner and outer sides of the salvage funnel 7.

[0028] like Figures 1 to 5 As shown, the rotary drive device includes a drive motor 4, a drive gear 40, a driven gear 41, and a transmission shaft 6. The drive motor 4 is mounted on the upper part of the mounting base 3. The output shaft end of the drive motor 4 is connected to the drive gear 40 via a key. The transmission shaft 6 is rotatably mounted on the connecting arm 5, and the scooping funnel 7 is connected to the output end of the transmission shaft 6. One end of the transmission shaft 6 is connected to the driven gear 41 via a key, and the drive gear 40 and the driven gear 41 mesh to form a reduction transmission mechanism for driving the scooping funnel 7 to rotate and scoop up scum.

[0029] When it is necessary to remove scum from the holding furnace 100, first start the linear motor 2, causing its slider to move the mounting base 3 and the rotary drive device horizontally, moving the scum removal funnel 7 directly above the holding furnace 100; then start the drive motor 4, which, through the meshing transmission of the drive gear 40 and the driven gear 41, drives the scum removal funnel 7 to rotate 180 degrees around the drive shaft 6, so that the opening of the scum removal funnel 7 cuts into the alloy liquid surface inside the holding furnace 100, and begins the rotary scum removal operation inside the holding furnace 100; after the scum removal funnel 7 enters the alloy liquid surface, the rotary drive device continues to control the scum removal funnel 7 to rotate slowly, ensuring that its rotation trajectory completely covers the entire cross-section of the holding furnace 100, thereby achieving a comprehensive and efficient scum removal operation; at the same time, the insulation cover 14 and the insulation frame 13 keep the furnace closed. In its closed state, the insulation cover 14 can shield and seal the insulation furnace 100 during the slag removal process, thus achieving the purpose of heat preservation. Furthermore, when the slag-removed hopper 7 is moved directly above the collection box 16, the closed insulation cover 14 and insulation frame 13 can insulate the hopper 7, facilitating the separation of slag and molten alloy. This effectively prevents the remaining molten alloy from prematurely solidifying in the hopper 7, causing separation difficulties and subsequent cleaning inconvenience. To prevent some molten alloy from solidifying in the outer filter holes of the hopper 7, the first cylinder 10 can be controlled to move the limiting arm 15 and the arc-shaped guide rail 11 synchronously, so that the limiting arm 15 separates from the opening 130 and the positioning groove 140 respectively, releasing the locking restriction on the insulation cover 14 (e.g., Figure 3 As shown), flip the insulation cover 14 upwards to remove the alloy liquid solidified in the filter hole outside the salvage funnel 7. After completion, return the insulation cover 14 to its original position and control the first cylinder 10 to drive the limiting arm 15 and the arc-shaped guide rail 11 to reset. The limiting arm 15 and the positioning groove 140 can lock and limit the insulation cover 14, thereby improving the insulation performance of the insulation structure.

[0030] Specific Implementation Example 2: Based on Specific Implementation Example 1, such as Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a collection box 16, a lower receiving frame 17, an upper receiving frame 18, and a filter screen 20. The collection box 16 is located on the other side of the base 1, directly below the retrieval funnel 7. The collection box 16 is equipped with a lower receiving frame 17 and an upper receiving frame 18 that can be pulled and moved. The collection box 16 is equipped with a filter screen 20, and the filter screen 20 is located at the bottom of the upper receiving frame 18 for separating scum from alloy liquid. The upper inner sides of the lower receiving frame 17 and the upper receiving frame 18 are respectively provided with inclined openings 19 for guiding scum.

[0031] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a lower receiving plate 21, an upper receiving plate 22, and a second cylinder 23. The lower receiving frame 17 and the upper receiving frame 18 are respectively connected to the lower receiving plate 21 and the upper receiving plate 22 on their outer sides. The lower side of the lower receiving plate 21 is in contact with the bottom of the collection box 16, and the lower side of the upper receiving plate 22 is in contact with the surface of the filter screen 20. Two relatively staggered second cylinders 23 are provided on the base 1, and the telescopic shafts of the two second cylinders 23 are respectively connected to the lower receiving plate 21 and the upper receiving plate 22.

[0032] like Figure 1 and Figure 9 As shown, it also includes a servo motor 24, an adjusting arm 25, and a nozzle 26. The servo motor 24 is installed on the front side of the insulation frame 13. The output shaft of the servo motor 24 is connected to the adjusting arm 25, and the nozzle 26 is connected to the adjusting arm 25. The nozzle 26 is used to spray the slag remover evenly into the insulation furnace 100 through the external pipeline to assist in slag removal. When it is necessary to add slag remover to the insulation furnace 100, the slag remover is automatically adsorbed and sprayed into the insulation furnace 100 through the external pipeline at one end of the nozzle 26. By controlling the servo motor 24 to rotate alternately in both directions, the adjusting arm 25 and the nozzle 26 are driven to swing back and forth to spray the slag remover evenly into the insulation furnace 100. This helps to save manpower, further assist in slag removal, improve the slag removal effect, and effectively ensure the uniformity of the slag remover spraying.

[0033] After the scum is removed, control the linear motor 2 to move its slider, which in turn moves the mounting base 3 and the rotary drive device horizontally to their reset positions, moving the scum removal funnel 7 directly above the collection box 16. Then, control the drive motor 4 to rotate the scum removal funnel 7 180 degrees in the opposite direction to its reset position, so that its opening faces downwards and the removed scum is poured onto the filter screen 20 of the upper receiving frame 18. The filter screen 20 filters and separates the scum and the attached molten alloy, keeping the scum on the screen while the molten alloy drips to the bottom of the collection box 16. The molten alloy at the bottom of the collection box 16 then solidifies. After solidification, a solid lead-antimony alloy is formed. At this point, the second cylinder 23 is first controlled to move the lower receiving plate 21 and the lower receiving frame 17 outward, so that the lower receiving frame 17 can push out the solidified lead-antimony alloy at the bottom of the collection box 16. Then, the other second cylinder 23 is controlled to move the upper receiving plate 22 and the upper receiving frame 18 outward, so that the upper receiving frame 18 can scrape off and clean the scum on the filter screen 20. After the operation is completed, it is only necessary to control the two second cylinders 23 respectively to move the lower receiving plate 21 and the lower receiving frame 17, as well as the upper receiving plate 22 and the upper receiving frame 18, back to their original positions.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
