Description

Technical Field

[0001] This utility model relates to the field of aluminum-chromium alloy preparation technology, and specifically to an aluminum-chromium alloy preparation apparatus. Background Technology

[0002] Aluminum-chromium alloy is a metal alloy with aluminum and chromium as the main components. It is usually made by melting in a specific ratio and may add small amounts of other elements to optimize its performance. It is widely used in many fields because of its high temperature resistance, corrosion resistance and high mechanical properties. In the preparation and production process of aluminum-chromium alloy, the prepared raw materials need to be melted and processed.

[0003] A search revealed an existing patent (publication number: CN210773397U) disclosing an energy-saving smelting furnace for aluminum alloy production. The furnace includes a fixed base, with fixed plates fixed to both sides of the top outer wall of the fixed base. Each of the two fixed plates has a rotating shaft rotatably connected to its opposite outer wall via bearings. A fixed frame is fixed between the opposite outer walls of the two rotating shafts. The inner wall of the fixed frame houses the furnace body. A drain pipe is located on one outer wall of the furnace body. The inner wall of the fixed frame has evenly spaced fixing teeth. Threaded holes are formed on both outer walls of the fixed frame, and fastening bolts are threaded into the inner walls of both threaded holes. This invention facilitates the pouring out of the molten metal, improves the safety of furnace operation, prevents heat loss from reducing melting efficiency, and prevents the furnace from falling off the fixed frame due to its own weight, thus preventing accidental injury to nearby operators.

[0004] However, the above solution makes it inconvenient to disassemble and replace the crucible. After use, the inner wall of the crucible needs to be cleaned and protected, and it also needs to be replaced after long-term use. However, the above solution makes disassembly and replacement inconvenient, which will increase the difficulty of disassembly and replacement for workers and make it inconvenient to use.

[0005] In view of this, the present invention proposes a preparation apparatus for aluminum-chromium alloys. Utility Model Content

[0006] This invention proposes a preparation device for aluminum-chromium alloys, which solves the problem of inconvenience in disassembling and replacing crucibles in related technologies.

[0007] The technical solution of this utility model is as follows: A preparation device for aluminum-chromium alloy includes a fixed frame; a controller fixedly connected to one side of the fixed frame; a furnace body rotatably connected to the upper end of the inner wall of the fixed frame; a heating groove is provided inside the furnace body; a groove is provided at the top of the furnace body at one end of the heating groove; an electromagnetic stirrer is fixedly connected to the inner bottom wall of the heating groove; a crucible is provided inside the heating groove at the top of the electromagnetic stirrer; a guide seat is fixedly connected to one end of the top of the crucible; an installation assembly mounted on the top of the furnace body, the installation assembly being used to assemble and disassemble the crucible; a reduction motor fixedly connected to the upper end of one side of the fixed frame; the output end of the reduction motor being fixedly connected to one side of the furnace body via a coupling; a furnace cover movably connected to the top of the furnace body; and a lifting assembly mounted on the other side of the fixed frame, the lifting assembly being used to adjust the furnace cover up and down.

[0008] The installation assembly includes: a limiting groove formed at an equal angle at the top of the crucible, the inner bottom wall of the limiting groove having bolt holes; and a limiting block fixedly connected at an equal angle to the top of the crucible surface, the top of the limiting block having a reserved groove, the inner bottom wall of the reserved groove being movably connected to a fixing bolt that is threaded into the bolt holes.

[0009] Preferably, the limiting block and the limiting groove form an engaging structure, and the limiting block and the limiting groove are convex in shape.

[0010] Preferably, the top of the crucible has placement grooves on both sides, and the placement grooves are arc-shaped.

[0011] Preferably, the cross-sectional area of ​​the furnace cover is larger than the cross-sectional area of ​​the internal opening of the crucible, and one side of the furnace cover is inverted L-shaped.

[0012] Preferably, a slot is provided on one side of the inner wall of the guide seat, a filter plate is movably connected to one side of the inside of the guide seat, and a locking block is fixedly connected to both ends of the filter plate.

[0013] Preferably, the filter plate is arc-shaped, and the inner wall of the guide seat is Y-shaped.

[0014] Preferably, the card block and the inside of the card slot form an engaging structure, and the shape of the card slot and the card block is an isosceles trapezoid.

[0015] Preferably, the lifting assembly includes: a fixed base fixedly connected to the upper end of the other side of the fixed frame; a hydraulic cylinder fixedly connected to the top of the fixed base, the output end of the hydraulic cylinder being fixedly connected to a sliding frame, and one side of the sliding frame being fixedly connected to the surface of the furnace cover.

[0016] Preferably, two ends of the bottom side of the sliding frame are fixedly connected to sliding rods, and the other side of the fixed frame is provided with a sliding groove that slides and engages with one end of the sliding rod.

[0017] Preferably, the upper end of the inner wall of the fixed frame is provided with symmetrically arranged auxiliary grooves in a ring, and the two sides of the furnace body are fixedly connected at equal angles with auxiliary blocks that slide and cooperate with the inside of the auxiliary grooves.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes an electromagnetic stirrer to agitate the molten metal inside the crucible without contact, facilitating faster and more uniform melting. The non-contact nature of the stirrer also prevents contamination of the molten metal. Furthermore, the engagement of the limiting block with the limiting groove, along with the threaded connection between the fixing bolt and the bolt hole, allows for easy disassembly and assembly of the crucible from the heating tank. This facilitates the removal of the crucible after melting for cleaning its inner wall, maintenance, and replacement, thus enhancing its practicality.

[0020] In this invention, the furnace body rotates due to the rotation of a geared motor. The molten metal is filtered through an arc-shaped filter plate and then guided out by a guide seat. The filter plate prevents slag from being discharged along with the molten metal, thus avoiding affecting the quality of the final product. Furthermore, after the furnace body rotates in the opposite direction at a certain angle, the slag is more likely to fall off the filter plate, reducing the possibility of slag clogging the filter plate. After smelting is completed, the filter plate can be pulled to allow the locking block to slide out of the slot, making it easy to remove the filter plate for cleaning and to prevent clogging.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0030] A preferred embodiment of the aluminum-chromium alloy preparation apparatus provided by this utility model is, for example... Figures 1 to 5 As shown: A preparation apparatus for aluminum-chromium alloy includes a fixed frame 4; a controller 9 fixedly connected to one side of the fixed frame 4; a furnace body 7 rotatably connected to the upper end of the inner wall of the fixed frame 4; a heating groove 12 is provided inside the furnace body 7; a groove 14 is provided at the top of the furnace body 7 at one end of the heating groove 12; an electromagnetic stirrer 8 is fixedly connected to the inner bottom wall of the heating groove 12; a crucible 3 is provided inside the heating groove 12 at the top of the electromagnetic stirrer 8; a guide seat 13 is fixedly connected to one end of the top of the crucible 3; an installation assembly 10 is assembled at the top of the furnace body 7, which is used to assemble and disassemble the crucible 3; a reduction motor 5 is fixedly connected to the upper end of one side of the fixed frame 4; the output end of the reduction motor 5 is fixedly connected to one side of the furnace body 7 through a coupling; a furnace cover 2 is movably connected to the top of the furnace body 7; and a lifting assembly 1 is assembled on the other side of the fixed frame 4, which is used to adjust the furnace cover 2 by sliding it up and down.

[0031] The mounting assembly 10 includes: a limiting groove 1006 formed at an equal angle at the top of the crucible 3, with bolt holes 1005 formed in the inner bottom wall of the limiting groove 1006; and a limiting block 1002 fixedly connected at an equal angle to the top of the surface of the crucible 3, with a reserved groove 1001 formed at the top of the limiting block 1002, and a fixing bolt 1003 movably connected to the inner bottom wall of the reserved groove 1001, which is threadedly engaged with the inside of the bolt hole 1005.

[0032] In this embodiment, the fixing bolt 1003 is rotated with a hex wrench or other tools until it is completely disengaged from the bolt hole 1005. Then, clamps are inserted into the placement groove 1004 and clamped onto the protrusions on both sides of the crucible 3, so that the crucible 3 can be removed from the heating tank 12, which facilitates cleaning of the inner wall of the crucible 3 or direct maintenance and replacement.

[0033] In a further preferred embodiment of the present invention, the limiting block 1002 and the limiting groove 1006 form an engaging structure, and the limiting block 1002 and the limiting groove 1006 are convex in shape.

[0034] In this embodiment, the engagement between the convex limiting block 1002 and the inside of the limiting groove 1006 is used to improve the firmness and stability of the crucible 3 when it is placed into the engaging installation.

[0035] In a further preferred embodiment of the present invention, placement grooves 1004 are provided on both sides of the top of the crucible 3, and the shape of the placement grooves 1004 is arc-shaped.

[0036] In this embodiment, the arc-shaped placement groove 1004 is used to facilitate the insertion of clamps to clamp the protrusions on both sides of the crucible 3.

[0037] In a further preferred embodiment of this utility model, the cross-sectional area of ​​the furnace cover 2 is larger than the cross-sectional area of ​​the internal opening of the crucible 3, and one side of the furnace cover 2 is inverted L-shaped.

[0038] In this embodiment, a furnace cover 2 with a large area and an inverted L-shape on one side is used to completely cover the top of the crucible 3 and one end of the guide seat 13, thus preventing heat leakage. Example

[0039] Based on Example 1, a preferred embodiment of the aluminum-chromium alloy preparation apparatus provided by this utility model is as follows: Figures 1 to 5 As shown: A slot 15 is provided on one side of the inner wall of the guide seat 13, and a filter plate 16 is movably connected to one side inside the guide seat 13. The two ends of the filter plate 16 are fixedly connected to the locking blocks 17.

[0040] In this embodiment, the filter plate 16 is used to filter the metal slag to prevent the slag from being discharged together and affecting the quality of the final product. At the same time, after the smelting is completed, the filter plate 16 can be pulled to make the locking block 17 slide out of the locking groove 15, so that the filter plate 16 can be taken out for cleaning and anti-clogging.

[0041] In a further preferred embodiment of this utility model, the filter plate 16 is arc-shaped, and the inner wall of the guide seat 13 is Y-shaped.

[0042] In this embodiment, the Y-shaped guide seat 13 is used to guide the molten metal, making it easier to guide and discharge. The arc-shaped filter plate 16 is used to make it less likely for slag to adhere to the surface of the filter plate 16 and easier to fall off.

[0043] In a further preferred embodiment of the present invention, the card block 17 and the card slot 15 form an engaging structure, and the card slot 15 and the card block 17 are in the shape of an isosceles trapezoid.

[0044] In this embodiment, the engagement of the isosceles trapezoidal locking block 17 with the slot 15 improves the firmness and stability of the filter plate 16 during installation.

[0045] In a further preferred embodiment of the present invention, the lifting assembly 1 includes: a fixed seat 104 fixedly connected to the upper end of the other side of the fixed frame 4; a hydraulic cylinder 102 fixedly connected to the top of the fixed seat 104, and a sliding frame 101 fixedly connected to the output end of the hydraulic cylinder 102, with one side of the sliding frame 101 fixedly connected to the surface of the furnace cover 2.

[0046] In this embodiment, the sliding frame 101 is raised by activating the hydraulic cylinder 102, which in turn raises the furnace cover 2, making it easier to disassemble the crucible 3. After the furnace cover 2 is lowered, it can cover the top of the crucible 3 to prevent heat leakage.

[0047] In a further preferred embodiment of the present invention, two ends of a sliding rod 103 are fixedly connected to one end of the bottom of the sliding frame 101, and a sliding groove 105 is provided on the other side of the fixed frame 4 to slide and cooperate with one end of the sliding rod 103.

[0048] In this embodiment, the sliding of the sliding rod 103 inside the sliding groove 105 is used to improve the stability of the sliding frame 101 and the furnace cover 2 sliding up and down.

[0049] In a further preferred embodiment of this utility model, an auxiliary groove 6 is symmetrically and annularly provided on the upper end of the inner wall of the fixing frame 4, and auxiliary blocks 11 that slide and cooperate with the inside of the auxiliary groove 6 are fixedly connected at equal angles on both sides of the furnace body 7.

[0050] In this embodiment, the stability of the furnace body 7 when it rotates and tilts is improved by utilizing the sliding between the auxiliary block 11 and the inside of the auxiliary groove 6.

[0051] The working principle of this utility model is as follows: First, suitable aluminum and chromium metal powders are added into the crucible 3. Then, the hydraulic cylinder 102 is activated to lower the sliding frame 101, which in turn drives the furnace cover 2 to cover the top of the crucible 3. The heating tube inside the furnace body 7 is then used to heat the material inside the crucible 3. After melting for a period of time, the electromagnetic stirrer 8 is used to stir the molten metal inside the crucible 3 without contact, making the melting rate faster and more uniform. After melting is completed, the hydraulic cylinder 102 is activated to raise the furnace cover 2 and open one end of the guide seat 13. Then, the reduction motor 5 is activated to make the furnace body 7 rotate slowly, so that the molten metal inside the crucible 3 can be filtered through the arc-shaped filter plate 16 and then guided out by the guide seat 13.

[0052] Furthermore, the geared motor 5 can be restarted to make the furnace body 7 rotate in the opposite direction by a certain angle, so that the slag on the filter plate 16 falls off due to gravity, reducing the possibility of the slag clogging the filter plate 16. At the same time, after the smelting is completed, the filter plate 16 can be pulled to make the locking block 17 slide out of the slot 15, making it easy to remove the filter plate 16 for cleaning and to prevent clogging.

[0053] Simultaneously, the fixing bolt 1003 can be rotated with tools such as a hex wrench until it is completely disengaged from the bolt hole 1005. Then, clamps are inserted into the placement groove 1004 and held on the protrusions on both sides of the crucible 3, so that the crucible 3 can be removed from the heating tank 12 for easy cleaning or direct maintenance and replacement of the inner wall of the crucible 3. During installation, the crucible 3 is placed into the heating tank 12, and the limiting block 1002 is engaged with the limiting groove 1006. Then, the fixing bolt 1003 is placed into the reserved groove 1001 and tightened into the bolt hole 1005.

[0054] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
