DETAILED DESCRIPTION

[0019] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0020] See also Figure 1-6 , the embodiment of the present application discloses a smelting furnace for recycling aluminum materials. Figure 1 and Figure 2 As shown, a melting furnace for aluminum material recovery includes a furnace body 1 and a cleaning unit 2. A feed port 11 is provided at the top of the furnace body 1, and a furnace cover 13 is provided at the feed port 11. The furnace cover 13 is buckled on the top of the furnace body 1 and is locked and fixed on the furnace body 1 by a buckle 14. The bottom of the furnace body 1 is funnel-shaped and provided with a discharge port 12. A sealing column 3 is inserted in the discharge port 12 in a vertical direction. After the aluminum liquid is smelted, the worker will open the furnace cover 13 and extract the aluminum liquid in the furnace body 1 by tools.

[0021] The cleaning unit 2 includes a bracket 21, on which two hydraulic cylinders 22 are installed directly above the furnace body 1, the piston rods of the hydraulic cylinders 22 extend in the vertical direction and are connected to a lifting seat 23, a reduction motor 24 is installed on the upper surface of the lifting seat 23, the output shaft of the reduction motor 24 is coaxially arranged with the furnace body 1 and coaxially connected to a rotating shaft 25, and a scraper member 26 is provided on the rotating shaft 25. The hydraulic cylinder 22 can drive the lifting seat 23 to rise and fall, the reduction motor 24 on the lifting seat 23 can drive the rotating shaft 25 to rotate, and the rotating shaft 25 can drive the scraper member 26 to rotate to scrape off the waste slag attached to the inner side wall of the furnace body 1, the inner bottom wall of the furnace body 1 and the wall of the discharge port 12.

[0022] like Figures 3 to 6As shown, an upper magnetic ring 31 is installed on the top of the sealing column 3. When the rotating shaft 25 descends to the bottom of the furnace body 1, the rotating shaft 25 will abut against the upper magnetic ring 31, and the upper magnetic ring 31 will adsorb and fix the rotating shaft 25. At this time, the rotating shaft 25 will press down the sealing column 3 during the process of continuing to descend, so that the sealing column 3 is separated from the discharge port 12, so that the waste slag scraped by the scraper 26 can be discharged through the discharge port 12.

[0023] A positioning plate 32 is installed at the bottom of the sealing column 3, and the lower surface area of ​​the positioning plate 32 is larger than the lower surface area of ​​the sealing column 3. When the rotating shaft 25 rises and resets, the rotating shaft 25 will drive the upper magnetic ring 31 and the sealing column 3 to rise synchronously until the positioning plate 32 is blocked by the bottom of the furnace body 1. At this time, the rotating shaft 25 will be separated from the upper magnetic ring 31 and continue to rise, and the sealing column 3 will be closed at the discharge port 12.

[0024] like Figure 2 and Figure 3 As shown, the scraper member 26 includes a mounting plate 264, a side scraper 261, a lower scraper 262 and an inner scraper 263. The mounting plate 264 is horizontally mounted on the side wall of the rotating shaft 25, the side scraper 261 is mounted on the lower scraper 262, and the side scraper 261 and the lower scraper 262 together form a "V"-shaped plate. Two limit rods 265 are installed on the lower scraper 262, and the limit rods 265 are slidably penetrated in the mounting plate 264 along the vertical direction, so that the lower scraper 262 and the side scraper 261 can only be lifted and lowered relative to the mounting plate 264; the lower scraper 262 and the mounting plate 264 are commonly connected to a vertically arranged first spring 266, and the inner scraper 263 is mounted on the side wall of the rotating shaft 25.

[0025] During the process of the rotating shaft 25 rotating and descending, the side scraper 261 will first scrape off the waste slag attached to the inner side wall of the furnace body 1; when the rotating shaft 25 moves to the bottom of the furnace body 1, the lower scraper 262 will scrape off the waste slag attached to the inner bottom wall of the furnace body 1. At this time, the lower scraper 262 and the side scraper 261 will no longer descend, and the first spring 266 will be gradually compressed; then the rotating shaft 25 will press down the sealing column 3, and the inner scraper 263 will be embedded in the discharge port 12 and scrape off the waste slag attached to the wall of the discharge port 12, thereby realizing the gradual cleaning of the waste slag from top to bottom, avoiding the ineffective wear of the scraper member 26 as much as possible, and thus improving the service life of the scraper member 26.

[0026] like Figures 4 to 6As shown, two symmetrical receiving grooves 33 are provided on the side wall of the sealing column 3, and a clamping block 34 is slidably embedded in the receiving groove 33 in the horizontal direction. The clamping block 34 is connected to the sealing column 3 through a second spring 35; a clamping groove 15 is provided on the wall of the discharge port 12. During the use of the furnace body 1, the clamping block 34 will be clamped in the clamping groove 15, at which time the second spring 35 will be in a natural state, and the sealing column 3 will be clamped and fixed and closed in the discharge port 12, thereby improving the stability of the sealing column 3 when it is closed in the discharge port 12.

[0027] It is worth mentioning that a sleeve 36 is installed on the lower surface of the positioning plate 32, and a square rod 54 is embedded in the sleeve 36 for sliding along the vertical direction. The square rod 54 can be fixed on any non-moving object. The sliding cooperation between the square rod 54 and the sleeve 36 prevents the sealing column 3 from being driven to rotate by the rotating shaft 25, so as to ensure that the block 34 can still be accurately inserted into the slot 15 after the sealing column 3 is raised or lowered.

[0028] A driving unit 4 is provided on the sealing column 3, and the driving unit 4 includes a slide groove 41 arranged at the top of the sealing column 3, the slide groove 41 is connected to the two accommodating grooves 33, and an upper slider 42 and a lower slider 43 are slidably embedded in the slide groove 41 along the vertical direction. The upper slider 42 and the lower slider 43 are connected by a vertically arranged connecting rod 44, the upper slider 42 is slidably embedded in the upper magnetic ring 31, and the upper slider 42 is connected to the sealing column 3 through a third spring 45, and the lower slider 43 is connected to the block 34 through a pull rope 46.

[0029] During the use of the furnace body 1, the third spring 45 will be in a natural state, the upper surface of the upper slider 42 will be flush with the upper surface of the upper magnetic ring 31, so that the waste slag in the furnace body 1 is not easy to enter the upper magnetic ring 31, and the lower slider 43 will be located below the block 34.

[0030] A pressure rod 27 is provided at the bottom of the rotating shaft 25, which can be slidably embedded in the upper magnetic ring 31 and the slide groove 41. When the rotating shaft 25 descends to the upper magnetic ring 31, the upper magnetic ring 31 will adsorb and fix the rotating shaft 25, and the pressure rod 27 will be downwardly embedded in the upper magnetic ring 31 and the slide groove 41. The upper sliding block 42 will be pressed down by the pressure rod 27 and drive the lower sliding block 43 to descend through the connecting rod 44. The lower sliding block 43 will drive the card block 34 to slide out of the card groove 15 through the pull rope 46. At this time, the rotating shaft 25 can press down the sealing column 3, so that the sealing column 3 is separated from the discharge port 12, so as to discharge the waste slag in the furnace body 1.

[0031] A top block 16 is slidably embedded in the slot 15, and the top block 16 is connected to the furnace body 1 through the fourth spring 17. When the rotating shaft 25 presses the sealing column 3 downward to disengage from the discharge port 12, the block 34 will slide and disengage from the slot 15. At this time, the fourth spring 17 will return to a natural state and drive the top block 16 to move, so that the side of the top block 16 facing the center of the discharge port 12 is located on the same annular surface as the wall of the discharge port 12, so that the waste residue in the discharge port 12 is not easy to enter the slot 15.

[0032] like Figures 3 to 5 As shown, an aggregate shell 5 is installed at the bottom of the furnace body 1, the top of the aggregate shell 5 is open and closed by the bottom of the furnace body 1, the discharge port 12 is connected to the top of the aggregate shell 5, the bottom of the aggregate shell 5 is funnel-shaped and is provided with a slag discharge port 51, and the waste slag discharged through the discharge port 12 will enter the aggregate shell 5 and be discharged through the slag discharge port 51.

[0033] A guide ring 53 is connected to the aggregate shell 5 through multiple support rods 52, and a square rod 54 is installed on the support rod 52. The height of the upper surface of the guide ring 53 gradually decreases from its center to its edge; the sealing column 3 is slidably embedded in the inner side of the guide ring 53 along the vertical direction, and a lower guide surface 342 inclined downward is provided on one end of the block 34 for embedding into the slot 15. During the process of the rotating shaft 25 pressing down the sealing column 3, the sealing column 3 will be embedded downward into the guide ring 53, and the upper surface of the guide ring 53 can press the block 34 into the accommodating groove 33 through the lower guide surface 342, so that the block 34 can be embedded into the inner side of the guide ring 53. At this time, the sealing column 3 will be separated from the discharge port 12, and the top of the sealing column 3 will also be embedded in the guide ring 53. The waste residue discharged from the discharge port 12 will directly fall to the bottom of the aggregate shell 5 through the upper surface of the guide ring 53, so as to prevent the waste residue in the discharge port 12 from adhering to the side of the sealing column 3 and the block 34.

[0034] A lower magnetic ring 55 is installed at the bottom of the guide ring 53. During the use of the furnace body 1, the clamping block 34 will be clamped in the clamping groove 15, so that the sealing column 3 is locked and fixed in the discharge port 12; at the same time, the positioning plate 32 will abut against the bottom of the guide ring 53, and the lower magnetic ring 55 will adsorb and fix the positioning plate 32, thereby improving the stability of the sealing column 3 in the discharge port 12 to prevent the sealing column 3 from sinking and detaching from the discharge port 12 due to the excessive weight of the aluminum liquid in the furnace body 1.

[0035] The aggregate shell 5, the discharge port 12 and the furnace body 1 are arranged coaxially, and a cleaning leaf 56 arranged in a "V" shape is arranged in the aggregate shell 5, and a magnetic block 57 is installed on the cleaning leaf 56, and the cleaning leaf 56 abuts against the upper surface of the guide ring 53 and the inner bottom wall of the aggregate shell 5; an annular guide rail 58 is installed at the bottom of the furnace body 1, and the guide rail 58 is located on the inner side of the aggregate shell 5. The cleaning leaf 56 slides on the guide rail 58, so that the cleaning leaf 56 rotates around the axis of the discharge port 12 and is connected to the furnace body 1. When the sealing column 3 is separated from the discharge port 12, so that the waste residue in the discharge port 12 is discharged, the inner scraper 263 will be located at the cleaning leaf 56, and the magnetic block 57 will adsorb and fix the inner scraper 263. At this time, the rotating shaft 25 will drive the cleaning leaf 56 to rotate and clean the upper surface of the guide ring 53 and the inner bottom wall of the aggregate shell 5 during the rotation process, so as to prevent the waste residue from adhering to the guide ring 53 and the aggregate shell 5.

[0036] An upper guide surface 341 inclined upward is provided on one end of the block 34 for embedding into the slot 15. When the sealing column 3 is embedded upward into the discharge port 12, the lower surface of the guide ring 53 and the bottom of the furnace body 1 can press the block 34 into the accommodating slot 33 through the upper guide surface 341, so that the sealing column 3 rises and returns to the discharge port 12.

[0037] The working principle of the present application is as follows: after the aluminum liquid in the furnace body 1 is discharged, the hydraulic cylinder 22 will drive the lifting seat 23 to descend, the reduction motor 24 on the lifting seat 23 will drive the rotating shaft 25 to rotate, and the rotating shaft 25 will drive the side scraper 261, the lower scraper 262 and the inner scraper 263 to rotate, the side scraper 261 first scrapes off the waste slag attached to the inner side wall of the furnace body 1, and the lower scraper 262 then scrapes off the waste slag attached to the inner bottom wall of the furnace body 1, and the inner scraper 263 is then embedded in the discharge port 12 and scrapes off the waste slag attached to the wall of the discharge port 12, thereby realizing the gradual cleaning of the waste slag from top to bottom.

[0038] During the process of the inner scraper 263 cleaning the waste slag, the pressure rod 27 will press down the upper slider 42, the upper slider 42 will drive the lower slider 43 to slide down through the connecting rod 44, and the lower slider 43 will drive the card block 34 to slide out of the card slot 15 through the pull rope 46; the upper magnetic ring 31 will adsorb and fix the rotating shaft 25, and the rotating shaft 25 will press down the upper magnetic ring 31 and the sealing column 3, so that the sealing column 3 is separated from the discharge port 12, and the scraped waste slag in the furnace body 1 will be discharged through the discharge port 12, and the fourth spring 17 will prompt the top block 16 to move to the notch of the card slot 15, so that the waste slag in the discharge port 12 cannot enter the card slot 15.

[0039] Afterwards, the top of the sealing column 3 will be embedded in the guide ring 53, and the waste slag in the discharge port 12 will fall to the bottom of the aggregate shell 5 through the guide ring 53, and be discharged through the slag discharge port 51 at the bottom of the aggregate shell 5; the block 34 and the sealing column 3 will be embedded in the inner side of the guide ring 53 to prevent the waste slag from adhering to the side of the sealing column 3 and the block 34; and the rotating shaft 25 will cause the cleaning leaf 56 to rotate through the adsorption force of the magnetic block 57 and the inner scraper 263, and the cleaning leaf 56 will rotate to clean the upper surface of the guide ring 53 and the inner bottom wall of the aggregate shell 5, thereby realizing the cleaning of the inside of the aggregate shell 5.

[0040] When the waste residue is cleaned, the hydraulic cylinder 22 will drive the lifting seat 23 to rise and reset, the lifting seat 23 will drive the reduction motor 24 and the rotating shaft 25 to rise and reset, and the rotating shaft 25 will drive the sealing column 3 to rise and reset into the discharge port 12 for subsequent use of the furnace body 1.

[0041] In summary, the present application can achieve comprehensive cleaning and collection of waste slag inside the furnace body 1 by controlling the hydraulic cylinder 22 and the reduction motor 24, thereby improving the cleaning efficiency of the waste slag.
