Description

Technical Field

[0001] This invention belongs to the field of aluminum-zinc alloy waste recycling and metal smelting technology, specifically relating to a vacuum separation furnace that facilitates the separation of molten aluminum-zinc metal liquid. Background Technology

[0002] In the fields of aluminum-zinc alloy waste recycling and metal smelting, vacuum separation furnaces are key equipment for achieving efficient separation of molten aluminum and zinc. Their working principle utilizes the significant difference in boiling points between aluminum and zinc under vacuum conditions. By heating, zinc volatilizes into vapor, which is then condensed and recovered, while aluminum remains in liquid form, thus completing the separation and purification of both.

[0003] Existing vacuum separation furnaces typically have a rigid furnace body, requiring placement on a foundation surface such as a workshop floor or temporary work area during installation. However, in practical applications, ground conditions vary significantly across different locations:

[0004] Cement floors may become locally tilted due to uneven settlement during pouring, or develop cracks and bulges due to long-term use;

[0005] The workshop floor tiles may have unevenness due to insufficient laying precision or loose tiles.

[0006] Temporary sites (such as outdoor recycling stations) are mostly unpaved surfaces, which are easily affected by geological conditions to form natural slopes.

[0007] When the furnace body is placed on uneven ground, it will cause the entire furnace body to tilt, which will lead to a series of problems affecting the separation effect. The specific reasons are as follows:

[0008] Uneven distribution of molten metal: The core working area of ​​the separation furnace (separation chamber) must be kept horizontal to ensure that the molten aluminum and zinc form a uniform liquid layer within the chamber. If the furnace is tilted, the molten metal will accumulate on the lower side, resulting in uneven liquid layer thickness (thinner on the higher side, thicker on the lower side). Since the heat transfer efficiency in the molten metal is directly related to the liquid layer thickness, the thin liquid layer area heats up faster, and the excessively high zinc volatilization rate is easily accompanied by trace amounts of aluminum volatilization; the thick liquid layer area heats up slowly, and zinc volatilization is insufficient, ultimately leading to incomplete separation of aluminum and zinc and a decrease in product purity.

[0009] Vacuum flow path deviation: In a vacuum environment, zinc vapor needs to enter the condensation zone along a preset path. Tilting the furnace body will cause the relative position of the vapor guiding structure (such as baffles and channels) in the separation chamber to shift from the surface of the molten metal. The molten metal that accumulates on the lower side may block part of the vapor outlet, while on the higher side, the vapor will carry more aluminum droplets due to the thin liquid layer, resulting in aluminum impurities mixed in with the condensed zinc product.

[0010] Decreased equipment operational stability: When tilted, uneven stress occurs at the connection points between the furnace body and the vacuum system and heating components, which may lead to localized wear of the seals and compromise the airtightness of the vacuum environment. At the same time, the relative positional shift between the heating elements and the separation chamber can cause localized overheating, exacerbating the thermal fatigue of the furnace body materials and shortening the equipment's service life.

[0011] In existing technologies, the problem of uneven ground is usually addressed by using simple methods such as inserting metal sheets or stones to level it. However, such methods have poor stability (they are prone to displacement due to vibration), low leveling accuracy (it is difficult to control the horizontal error within ±5mm), and cannot adapt to the need for rapid switching between various sites. This seriously restricts the separation efficiency and product quality of vacuum separators under complex working conditions.

[0012] Therefore, developing an external structure for a vacuum separation furnace that can adapt to different ground conditions and achieve precise horizontal calibration of the furnace body is key to solving the problem of uneven separation of molten aluminum and zinc and improving the applicability of the equipment. Summary of the Invention

[0013] To address the problems in existing vacuum separation furnaces caused by uneven ground leading to tilting, resulting in poor separation efficiency, low equipment stability, and weak site adaptability, this invention provides a vacuum separation furnace that facilitates the separation of molten aluminum and zinc. By optimizing the external structural design, the furnace body achieves precise horizontal calibration, thereby improving separation efficiency and equipment applicability.

[0014] To achieve the above objectives, the present invention provides the following technical solution: a vacuum separation furnace for facilitating the separation of molten aluminum and zinc, comprising a vacuum separation furnace, a furnace body placement rack for placing and protecting the vacuum separation furnace, and a fixed placement box fixed to the ground;

[0015] The bottom of the furnace body placement frame is symmetrically provided with four mounting blocks in pairs. Each mounting block is equipped with a caster wheel at its bottom. The furnace body placement frame is connected to the four caster wheels through the four mounting blocks to slide on the ground. Each mounting block is provided with a fixing hole for fixing its position.

[0016] The fixed placement box is provided with a driving structure, a fixing structure, a lifting structure and an adjusting structure. The driving structure is installed in the fixed placement box. There are four sets of each of the fixing structure, lifting structure and adjusting structure. The four sets of fixing structure, the four sets of lifting structure and the four sets of adjusting structure are all connected to the working end of the driving structure.

[0017] The four sets of fixing structures are symmetrically installed in pairs on the fixed placement box, and all four sets of fixing structures can move horizontally on the fixed placement box. Each set of fixing structures can fix the position of one of the mounting blocks.

[0018] The four lifting structures are symmetrically installed in pairs on the fixed placement box, and all four lifting structures can move vertically on the fixed placement box. The four casters at the bottom of the furnace body placement frame are respectively located on one of the lifting structures. The four lifting structures can drive the four casters to rise under the drive of the drive structure, so that the furnace body placement frame and the vacuum separation furnace rise synchronously.

[0019] The four sets of adjustment structures are symmetrically installed on the drive structure in pairs, and each set of adjustment structures is connected to the lifting structure on the drive structure. The four sets of lifting structures can rise or fall synchronously under the drive of the drive structure, and each set of adjustment structures can drive one set of lifting structures to rise or fall independently.

[0020] Furthermore, the fixed placement box has four symmetrically arranged transverse openings in pairs, and each transverse opening is provided with a limiting assembly plate. The four sets of fixed structures are slidably installed on the fixed placement box through the four transverse openings and the four limiting assembly plates.

[0021] The fixed placement box is also provided with four longitudinal openings symmetrically arranged in pairs. Each longitudinal opening is provided with a limit assembly rod. The four sets of lifting structures are slidably installed on the fixed placement box through the four longitudinal openings and the four limit assembly rods.

[0022] Furthermore, the driving structure includes a driving component, two sets of transmission components one and two sets of transmission components two. The driving component is installed on the bottom end inside the fixed placement box. The two sets of transmission components one and the two sets of transmission components two are symmetrically installed at both ends of the driving component. The driving component can drive the two sets of transmission components one and the two sets of transmission components two to move in opposite directions.

[0023] Each set of transmission components one is connected to two sets of fixed structures, and each set of transmission components two is connected to two sets of lifting structures. The two sets of transmission components one can drive the four sets of fixed structures to move horizontally, and the two sets of transmission components two can drive the four sets of lifting structures to move vertically.

[0024] Furthermore, the driving component includes a driving rod, a driving mounting bracket, a driving placement bracket, a bevel gear set, two threaded rods, and two sets of limiting rods. The driving rod is rotatably mounted on the side end of the fixed placement box, with one end of the driving rod located outside the fixed placement box and able to be connected to the driving power supply, and the other end located inside the fixed placement box. The driving mounting bracket is mounted on the bottom end inside the fixed placement box, and the driving placement bracket is positioned in the middle of the driving mounting bracket.

[0025] The bevel gear set includes three meshing bevel gears, all of which are rotatably mounted in the drive placement frame. One of the bevel gears is connected to one end of the drive rod located inside the fixed placement box, and can be driven by the drive rod to drive the other two bevel gears to rotate in the opposite direction.

[0026] Two threaded rods are symmetrically arranged on both sides of the drive placement frame, and are rotatably installed between the drive placement frame and the drive mounting frame, and are respectively connected to the other two bevel gears; two sets of limiting rods are respectively located on both sides of the two threaded rods, and are rotatably installed between the drive placement frame and the drive mounting frame.

[0027] Furthermore, each set of the transmission components includes a movable connecting frame, a movable connecting plate, two mounting columns, two sliding rods, and two rotating connecting rods. The movable connecting frame is slidably assembled on a set of the limiting rods and threadedly connected to the threaded rod, and can move horizontally on the limiting rod as the threaded rod rotates.

[0028] The movable connecting plate is installed on the upper end of the movable connecting frame, and its two sides pass through the two transverse openings and are slidably connected to the limiting assembly plate in the transverse openings; the two mounting columns are symmetrically arranged on both sides of the movable connecting plate and located outside the fixed placement box; the bottom end of each sliding rod is slidably installed in one of the mounting columns, and each rotating connecting rod is installed on the top end of one of the sliding rods; the two sets of fixed structures are installed outside the fixed placement box through the two rotating connecting rods.

[0029] Furthermore, each set of the transmission components includes a movable slider, a movable lifting frame, and two sets of limiting rods. The movable slider is slidably mounted on the limiting rod and threadedly connected to the threaded rod, located on one side of the movable connecting frame, and its top end is an inclined surface.

[0030] The movable lifting frame is located inside the fixed placement box and between the two sets of lifting structures, above the drive mounting frame. An assembly opening is provided in the middle of the frame, and the top of the assembly opening is inclined and matches the inclined surface of the top of the movable slider.

[0031] The movable lifting frame has symmetrically arranged assembly slots on both sides. Each set of limiting rods is installed in one of the assembly slots. The movable lifting frame is connected to two sets of lifting structures through the limiting rods on both sides. Each set of adjusting structures is connected to one set of lifting structures in one of the assembly slots.

[0032] Furthermore, each set of the fixing structure includes a rotating mounting sleeve, a U-shaped assembly frame, and a fixed assembly rod. The rotating mounting sleeve is mounted on the rotating connecting rod and there is frictional resistance between the two. The U-shaped assembly frame is mounted on one side of the rotating mounting sleeve, and the fixed assembly rod is mounted inside the U-shaped assembly frame, which can correspond and cooperate with the fixing hole on the mounting block.

[0033] Furthermore, each lifting structure includes a lifting plate, a fixed connecting plate, and a connecting assembly plate. The lifting plate is located outside the fixed placement box and on the ground, and is provided with a pulley groove for positioning the caster wheels.

[0034] The fixed connecting plate is located in the longitudinal opening and is slidably connected to the limiting assembly rod. One side of the plate is connected to the lifting plate, and the other side is connected to the connecting assembly plate.

[0035] The connecting assembly plate is located inside the fixed placement box and in the assembly slot on one side of the movable lifting frame. It is slidably connected to the second limiting rod. A threaded sleeve is provided at the connection point between the plate and the working end of the adjusting structure, and the plate is connected to the adjusting structure through the threaded sleeve.

[0036] Furthermore, each set of adjustment structures includes a threaded rod II, a transmission rod, a nut, a rotating connecting plate, and two sliding assembly blocks. The threaded rod II is rotatably disposed in the assembly groove on one side of the movable lifting frame and is threadedly connected to the threaded sleeve.

[0037] The bottom end of the transmission rod is connected to the top end of the threaded rod II, and the top end extends outward through the top of the fixed placement box, with two sliding assembly slots symmetrically opened on it.

[0038] The nut is sleeved on the transmission rod and located above the fixed placement box. Its bottom end is rotatably mounted on the top of the fixed placement box through the rotating connecting plate. Two sliding assembly blocks are symmetrically arranged on the inner side, and each sliding assembly block is located in a sliding assembly groove.

[0039] In summary, the present invention has the following main beneficial effects:

[0040] 1. In existing technologies, the height adjustments of each support point (base material) interfere with each other during ground leveling, making it difficult to achieve independent fine-tuning. This invention, through the coordination of "a drive structure driving four sets of lifting structures to rise synchronously → four sets of adjustment structures independently controlling the lifting of a single set of lifting structures", first raises the entire furnace body to a unified reference height, and then achieves precise height compensation for each support point through independent adjustment. It can specifically correct tilt in any direction and greatly improve the level calibration accuracy (far exceeding the ±5mm error range of existing technologies).

[0041] 2. In existing technologies, when leveling directly on the ground, the furnace support point is in direct contact with uneven ground (such as cracks, protrusions, and loose floor tiles), and the leveling accuracy is limited by local defects in the ground. This invention completely lifts the furnace placement frame off the ground through a lifting structure, and the support point is transformed into a controllable lifting structure, completely eliminating the interference of the original state of the ground. From the support foundation, it ensures that the leveling is not affected by the difference in elevation of the site, settlement and other problems.

[0042] 3. Existing technology only uses a mat for leveling, and the furnace body is not rigidly connected to the ground. The mat is easily displaced due to equipment vibration or external force, which can damage the leveled state. This invention uses the cooperation of "fixed structure to preferentially connect furnace body placement frame and lifting structure" to rigidly fix the furnace body and lifting system before lifting. During subsequent adjustment, the furnace body and lifting structure always remain relatively stationary, avoiding leveling deviation caused by furnace body sliding during adjustment.

[0043] 4. Existing technologies require finding suitable paving materials when switching between different sites (such as cement floors or temporary unpaved surfaces), and differences in ground flatness may lead to completely different leveling logic. This invention, through the combination of "omnidirectional wheel movement + standardized docking of fixed placement boxes", allows the furnace body to be quickly transferred to a fixed placement box in any site. Leveling is completed through a unified "fixing → lifting → adjusting" process, without relying on the site's own conditions, significantly improving the efficiency and stability of cross-site operations.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] The embodiments of the present invention will now be described.

[0056] Example 1

[0057] Please see Figures 1-9 The present invention provides a technical solution:

[0058] A vacuum separation furnace for facilitating the separation of molten aluminum and zinc metal includes a vacuum separation furnace 1, a furnace body placement rack 2, and a fixed placement box 3, wherein:

[0059] Furnace body placement frame 2: used to support the vacuum separation furnace. Four mounting blocks 21 are symmetrically welded to the bottom of the frame. Each mounting block 21 is fixed with casters 22 by bolts, so that the furnace body placement frame 2 can slide on the ground. Each mounting block 21 has a fixing hole 211 on its side, which is used to cooperate with the fixing structure 5 to achieve positioning.

[0060] Fixed placement box 3: It is fixed to the ground by expansion bolts. The internal drive structure 4 is integrated. The external four fixed structures 5 and four lifting structures 6 are installed through the horizontal opening 31, the limiting assembly plate 32, the longitudinal opening 33 and the limiting assembly rod 34. The four adjusting structures 7 are inserted through the top of the fixed placement box 3 and connected to the lifting structures 6.

[0061] The specific assembly and working process of drive structure 4:

[0062] In the drive component 41, the drive mounting bracket 412 is welded to the bottom of the fixed placement box 3, and the drive placement bracket 413 is bolted to the middle of the drive mounting bracket 412; the three bevel gears of the bevel gear set 414 are rotatably mounted in the drive placement bracket 413 through bearings, one of the bevel gears is keyed to the drive rod 411 (extending to the outside of the box), and the other two bevel gears are keyed to one end of the two threaded rods 415 respectively, and the other end of the threaded rods 415 is rotatably supported on the drive mounting bracket 412 through bearings; the two sets of limit rods 416 are parallel to the threaded rods 415, and their two ends are welded to the drive placement bracket 413 and the drive mounting bracket 412 respectively.

[0063] When the drive rod 411 is driven to rotate by an external drive source (such as a motor or manual crank), it is transmitted through the bevel gear set 414, causing the two threaded rods 415 to rotate synchronously in opposite directions, thereby driving the transmission component 42 and the transmission component 43 to move.

[0064] The fit between transmission component 42 and fixed structure 5:

[0065] The movable connecting frame 421 is threadedly connected to the threaded rod 415 and sleeved on the limiting rod 416, and moves horizontally as the threaded rod 415 rotates; the movable connecting plate 422 is welded to the top of the movable connecting frame 421, and passes through the transverse opening 31 on both sides and slides in cooperation with the limiting assembly plate 32 (welded to the inner wall of the transverse opening 31); two mounting columns 423 are welded to both sides (outside the box) of the movable connecting plate 422, the bottom end of the sliding rod 424 is inserted into the mounting column 423 (can slide up and down), and the top end is welded to the rotating connecting rod 425.

[0066] In the fixed structure 5, the rotating mounting sleeve 51 is fitted onto the rotating connecting rod 425 (interference fit, with frictional resistance), the U-shaped assembly frame 52 is welded to the side of the rotating mounting sleeve 51, and the fixed assembly rod 53 is welded to the inside of the U-shaped assembly frame 52. When the moving connecting frame 421 drives the rotating connecting rod 425 to move horizontally, the U-shaped assembly frame 52 approaches the mounting block 21, the fixed assembly rod 53 is inserted into the fixing hole 211, and at the same time, the U-shaped assembly frame 52 clamps the mounting block 21 from both sides, realizing the rigid fixation between the furnace body placement frame 2 and the lifting structure 6; when not in use, the rotating mounting sleeve 51 can be rotated to make the U-shaped assembly frame 52 perpendicular to the box wall, so as not to hinder the movement of the furnace body placement frame 2.

[0067] The connection between transmission component 43 and lifting structure 6:

[0068] The movable slider 431 is threadedly connected to the threaded rod 415 and sleeved on the limiting rod 416 (located outside the movable connecting frame 421), with its top end being a 45° inclined surface; the movable lifting frame 432 is located above the drive mounting frame 412, with the top end of the central mounting opening 433 being a matching 45° inclined surface, and the limiting rod 435 is welded into the mounting grooves 434 on both sides.

[0069] In the lifting structure 6, the lifting plate 61 is located on the ground outside the box, and its surface is provided with a pulley groove 611 that matches the universal wheel 22. The pulley groove 611 can not only restrict the universal wheel 22 from sliding laterally during the lifting process, but also ensure that when the furnace body placement frame 2 moves onto the lifting plate 61, the position of the universal wheel 22 and the lifting structure 6 are precisely aligned, providing a positioning reference for the subsequent docking of the fixing structure 5 and the mounting block 21. One end of the fixing connecting plate 62 is welded to the lifting plate 61, and the other end passes through the longitudinal opening 33 and is welded to the connecting assembly plate 63, and slides in cooperation with the limiting assembly rod 34 (welded to the hole wall) in the longitudinal opening 33. The connecting assembly plate 63 is sleeved on the limiting rod 435 and can slide up and down along it, and a threaded sleeve 64 is welded to the side.

[0070] When the threaded rod 415 drives the movable slider 431 to move towards the movable lifting frame 432, the inclined surface at the top of the movable slider 431 fits against the inclined surface at the top of the assembly opening 433. As the movable slider 431 continues to move, the movable lifting frame 432 is lifted up (it cannot move horizontally due to the limitation of the lifting structures 6 on both sides). Then, through the limit rod 435, the connecting assembly plate 63, the fixed connecting plate 62 and the lifting plate 61 rise synchronously, realizing the overall lifting of the furnace body placement frame 2.

[0071] The leveling process of adjusting structure 7:

[0072] The threaded rod 71 is rotatably mounted in the assembly groove 434 via a bearing and is threadedly connected to the threaded sleeve 64; the bottom end of the transmission rod 72 is welded to the top end of the threaded rod 71, and the top end passes through the top of the fixed placement box 3, with sliding assembly grooves 721 on both sides; the nut 73 is mounted on the top of the fixed placement box 3 via a rotating connecting plate 74 (bearing connection), and the inner sliding assembly block 75 is embedded in the sliding assembly groove 721.

[0073] When the furnace body placement frame 2 is lifted off the ground, the rotating nut 73 drives the transmission rod 72 to rotate through the cooperation of the sliding assembly block 75 and the sliding assembly groove 721, thereby driving the threaded rod 71 to rotate. The threaded sleeve 64 drives the connecting assembly plate 63 to rise and fall along the limit rod 435, realizing the independent height adjustment of a single lifting structure 6. The furnace body is leveled through the cooperation of four sets of adjustment structures 7.

[0074] Auxiliary support: After the furnace body is leveled, rubber pads, wooden blocks and other support components are inserted into the bottom of the lifting plate 61 to share the load of the lifting structure 6 and extend the service life of the equipment.

[0075] Through the above-mentioned structural combination, the present invention achieves precise horizontal calibration of the vacuum separation furnace under different ground conditions, effectively solving the problems of poor separation effect, low stability and weak adaptability in the prior art, and significantly improving the aluminum-zinc separation efficiency and equipment durability.

[0076] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
