Description

Technical Field

[0001] This utility model relates to the field of alloy furnace technology, specifically to an electromagnetic stirring device for molten aluminum in an alloy furnace. Background Technology

[0002] In the field of aluminum alloy production and processing, the alloy furnace is the core equipment for aluminum melting and composition adjustment, and the uniformity of the molten aluminum directly determines the mechanical properties and quality stability of the subsequent castings.

[0003] Currently, most alloy furnaces employ a fixed furnace structure. During material feeding, the furnace body must be tilted or a specialized scooping device must be used to remove molten aluminum. Furthermore, the alloy furnace generates a large amount of high-temperature waste gas containing dust and harmful gases during the smelting process. Direct emission of this waste gas not only causes environmental pollution but also results in significant energy waste. While some existing alloy furnaces are equipped with waste gas treatment devices, they mostly employ simple filtration and direct emission methods, lacking effective waste heat recovery structures and resulting in low energy utilization. Simultaneously, the filter components are mostly fixed installations, and their filtration efficiency decreases after long-term use. The entire treatment device must be disassembled for cleaning or replacement, making operation complex and maintenance costs high, severely impacting the continuous and stable operation of the alloy furnace. Utility Model Content

An air outlet pipe is provided, with a filter cartridge fixedly connected to the outer wall of one end of the air outlet pipe extending from the top of the cover plate. A sealing end cap is installed on the inner wall of the filter cartridge at the end away from the air outlet pipe. Symmetrically distributed threaded sleeves are rotatably connected to the filter cartridge. A stud is threadedly connected to the inner wall of the threaded sleeve. A square locking block is fixedly connected to one end of the stud extending from the threaded sleeve, and the square locking block engages with the sealing end cap. Symmetrically distributed connecting rods are fixedly connected to the side of the sealing end cap near the air outlet pipe. A positioning block is fixedly connected to the other end of the connecting rod. A filter plate is fixedly connected between the two positioning blocks.

[0006] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace is provided, which further includes: a conveying hose fixedly connected to the sealed end cover, and a heat exchanger fixedly connected to the other end of the conveying hose, and the heat exchanger fixedly connected to a U-shaped frame, and a fan fixedly connected to the side of the heat exchanger away from the conveying hose.

[0007] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace further includes: symmetrically distributed square slots on both sides of the sealing end cover, the square slots being adapted to square blocks. The square slots and square blocks limit the sealing end cover when the square blocks enter the square slots.

[0008] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace is provided, which further includes: symmetrically distributed sliding grooves on both sides of the inner wall of the filter cylinder, and the inner wall of the sliding groove is slidably connected to a square locking block.

[0009] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for aluminum molten metal in an alloy furnace is provided, which further includes: a second bevel gear rotatably connected to the outer wall of the filter cylinder, a first bevel gear symmetrically distributed meshing on one side of the second bevel gear, and the inner wall of the first bevel gear being fixedly connected to a threaded sleeve.

[0010] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace is provided, which further includes: symmetrically distributed positioning grooves on the inner wall of the filter cylinder, and the inner wall of the positioning groove is slidably connected to the positioning block.

[0011] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace is provided, which further includes: a discharge port is provided on one side of the top of the alloy furnace body, and a sealing block is fixedly connected to one side of the bottom of the cover plate, and the sealing block is adapted to the discharge port.

[0012] For example, in at least one embodiment of the present invention, an electromagnetic stirring device for molten aluminum in an alloy furnace is provided, which further includes: symmetrically distributed support plates fixedly connected to both sides of the U-shaped frame, symmetrically distributed cylinders provided on the side of the two vertical plates that are far apart from each other, and the driving end of the cylinders being fixedly connected to the support plates.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, during use, the fan is started, and the fan causes the waste gas generated in the alloy furnace body to enter the filter cartridge through the exhaust pipe. When the waste gas flows through the filter plate, the impurities are filtered out by the filter plate. Then, it is transported to the heat exchanger through the conveying hose for heat exchange, realizing waste heat recovery, and is discharged by the fan. 2. In this utility model, during cleaning, rotating one of the threaded sleeves causes the first bevel gear to rotate. The first bevel gear drives the other first bevel gear to rotate through the second bevel gear, causing the two threaded sleeves to rotate synchronously. The rotation of the threaded sleeves causes the stud to move, which in turn causes the square locking block to move along the slide groove. The two square locking blocks move away from each other and disengage from the square locking groove, causing the square locking block to lose its limiting effect on the sealing end cover. The sealing end cover can then be pulled out, allowing it to move the filter plate out of the filter cylinder through the connecting rod and positioning block, thus cleaning the filter plate. This makes it easy to install and disassemble, and easy to clean. Attached Figure Description

The device includes an alloy furnace body 1, an electromagnetic stirrer 2 mounted on the bottom outer wall of the alloy furnace body 1, rotating shafts 3 fixedly connected to both outer walls of the alloy furnace body 1, symmetrically distributed upright plates 4 on both sides of the alloy furnace body 1, and the upright plates 4 rotatably connected to the rotating shafts 3. A cover plate 10 abuts against the top of the alloy furnace body 1, a connecting column 29 fixedly connected to the top of the cover plate 10, and a U-shaped frame 9 slidably connected to the top of the connecting column 29. An exhaust pipe 15 is fixedly connected inside the cover plate 10, and a filter cylinder 14 is fixedly connected to the outer wall of one end of the exhaust pipe 15 extending from the top of the cover plate 10. A filter cylinder 14 is installed on the inner wall of the end of the filter cylinder 14 furthest from the exhaust pipe 15. A symmetrically distributed threaded sleeve 27 is rotatably connected to the sealing end cap 19 and the filter cylinder 14. A stud 25 is threadedly connected to the inner wall of the threaded sleeve 27. A square locking block 23 is fixedly connected to one end of the stud 25 extending out of the threaded sleeve 27, and the square locking block 23 is engaged with the sealing end cap 19. A symmetrically distributed connecting rod 18 is fixedly connected to the side of the sealing end cap 19 near the gas outlet pipe 15. A positioning block 22 is fixedly connected to the other end of the connecting rod 18. A filter plate 16 is fixedly connected between the two positioning blocks 22. The electromagnetic stirring of the molten aluminum in the alloy furnace body 1 is achieved by the electromagnetic stirrer 2. The alloy furnace body 1 is rotatably connected to the vertical plate 4 by the rotating shafts 3 on both sides of the alloy furnace body 1, so that the alloy furnace body 1 can rotate. That is, the alloy furnace body 1 can be rotated to feed the molten aluminum when feeding.

[0026] The electromagnetic stirrer 2 adopts a medium-frequency electromagnetic stirring structure with a stirring power of 5-15kW, a magnetic field strength of 0.1-0.3T, and a working frequency of 50-200Hz. The electromagnetic stirrer 2 is fixedly connected to the bottom of the alloy furnace body 1 through a high-temperature resistant insulating gasket to avoid interference of the magnetic field on the metal structure of the alloy furnace body 1.

[0027] The filter plate 16 adopts a double-layer high-temperature resistant ceramic filter element. The inner layer has a pore size of 5-10μm (filtering fine dust) and the outer layer has a pore size of 50-100μm (filtering coarse impurities).

The positioning block 22 and the positioning groove 17 of the filter cylinder 14 are fitted with a clearance (the clearance is 0.1-0.2mm).

[0028] In some examples, a conveying hose 13 is fixedly connected to the sealed end cap 19, and a heat exchanger 11 is fixedly connected to the other end of the conveying hose 13. The heat exchanger 11 is fixedly connected to the U-shaped frame 9. A fan 12 is fixedly connected to the side of the heat exchanger 11 away from the conveying hose 13. The fan 12 is a CF-4-4 model. The fan 12 draws air from the alloy furnace body 1, so that the exhaust gas in the alloy furnace body 1 enters the filter cartridge 14 through the exhaust pipe 15, is filtered by the filter plate 16 and conveyed to the conveying hose 13. After heat exchange through the conveying hose 13, it is discharged by the fan 12 after treatment and discharge.

[0029] The heat exchanger 11 is a plate heat exchanger, the heat exchange medium is industrial water, the heat exchange area is 2-5㎡, the flow channel of the heat exchanger 11 is made of 316L stainless steel, which is resistant to high temperature and corrosion; the hot water after waste heat recovery is transported to the raw material preheating chamber of the alloy furnace through pipeline to realize the recycling of heat energy. The heat exchanger 11 is fixed to the U-shaped frame 9 by bolts, and vibration damping pads are provided at the connection.

[0030] In some examples, symmetrically distributed square slots 21 are provided on both sides of the sealing end cap 19. The square slots 21 are adapted to the square blocks 23. The square slots 21 and the square blocks 23 limit the sealing end cap 19 when the square blocks 23 enter the square slots 21.

[0031] In some examples, the inner walls of both sides of the filter cartridge 14 are provided with symmetrically distributed grooves 24, and the inner walls of the grooves 24 are slidably connected to the square blocks 23, guiding the square blocks 23 through the grooves 24.

[0032] In some examples, the outer wall of the filter cartridge 14 is rotatably connected to a second bevel gear 28, and a symmetrically distributed first bevel gear 26 meshes with one side of the second bevel gear 28. The inner wall of the first bevel gear 26 is fixedly connected to a threaded sleeve 27. The first bevel gear 26 is rotated by the rotation of the threaded sleeve 27, and then the second bevel gear 28 is used for transmission, so that the other first bevel gear 26 and the threaded sleeve 27 rotate, thereby realizing that the two square blocks 23 are close to each other or far away from each other.

[0033] In some examples, the inner wall of the filter cartridge 14 is provided with symmetrically distributed positioning grooves 17, and the inner wall of the positioning grooves 17 is slidably connected to the positioning block 22. The positioning grooves 17 facilitate the installation and positioning of the filter plate 16.

[0034] In some examples, a discharge port 20 is provided on one side of the top of the alloy furnace body 1, and a sealing block 30 is fixedly connected to one side of the bottom of the cover plate 10. The sealing block 30 is adapted to the discharge port 20, and the discharge port 20 facilitates the discharge of molten aluminum when the alloy furnace body 1 is tilted.

[0035] In some examples, symmetrically distributed support plates 8 are fixedly connected to both sides of the U-shaped frame 9. Cylinders 7 are symmetrically distributed on the side of the two vertical plates 4 that are far apart from each other. The driving end of the cylinder 7 is fixedly connected to the support plate 8. The model of the cylinder 7 is CQ2B63-50. The support plate 8 is moved by the cylinder 7, which in turn causes the U-shaped frame 9 to move the cover plate 10. This prevents the cover plate 10 and the U-shaped frame 9 from obstructing the alloy furnace body 1 when it is tilted to unload the material.

[0036] In some examples, the two upright plates 4 are fixedly connected to the side away from each other by a support plate 6, and the top of the support plate 6 is fixedly connected to the cylinder 7, so that the cylinder 7 is supported by the support plate 6.

[0037] In some examples, a motor 5 is fixedly connected to one of the upright plates 4. The output shaft of the motor 5 is fixedly connected to the rotating shaft 3. The model of the motor 5 is 130ST-M06025. The rotating shaft 3 is driven to rotate by the motor 5, which in turn causes the alloy furnace body 1 to rotate, making it convenient for the alloy furnace body 1 to tilt and unload materials.

[0038] In actual use, a controller can be installed on one of the upright plates 4. The controller is electrically connected to the motor 5, cylinder 7, and fan 12 respectively. The controller is not shown in the figure.

[0039] Working principle and usage process of this utility model: In this application, when in use, the electromagnetic stirrer 2 is started, which causes the molten aluminum in the alloy furnace body 1 to rotate, thereby achieving electromagnetic stirring. When feeding, the cylinder 7 is started, and the drive end of the cylinder 7 drives the support plate 8 to move, thereby causing the U-shaped frame 9 to move upward. The U-shaped frame 9 drives the cover plate 10 to move upward through the connecting column 29. Then, the motor 5 is started, and the drive end of the motor 5 drives the rotating shaft 3 to rotate, thereby causing the alloy furnace body 1 to rotate, causing the alloy furnace body 1 to tilt, thereby causing the molten aluminum to be discharged through the discharge port 20. In this application, during use, the blower 12 is started, and the blower 12 causes the waste gas generated in the alloy furnace body 1 to enter the filter cartridge 14 through the exhaust pipe 15. When the waste gas flows through the filter plate 16, the impurities are filtered out by the filter plate 16, and then it is transported to the heat exchanger 11 through the conveying hose 13 for heat exchange, realizing waste heat recovery, and then discharged through the blower 12. In this application, during cleaning, rotating one of the threaded sleeves 27 causes the first bevel gear 26 to rotate. The first bevel gear 26 drives the other first bevel gear 26 to rotate through the second bevel gear 28, causing the two threaded sleeves 27 to rotate synchronously. The rotation of the threaded sleeves 27 causes the stud 25 to move, which in turn causes the square locking block 23 to move along the slide groove 24. The two square locking blocks 23 move away from each other and disengage from the square locking groove 21, causing the square locking block 23 to fail to limit the sealing end cover 19. The sealing end cover 19 can then be pulled out, causing the sealing end cover 19 to move the filter plate 16 out of the filter cylinder 14 through the connecting rod 18 and the positioning block 22, so that the filter plate 16 can be cleaned. This facilitates assembly and disassembly and cleaning.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
