Description

Technical Field

[0001] The present invention belongs to the technical field of alloy melting, and specifically relates to a vacuum alloy melting furnace. Background Art

[0002] A vacuum alloy melting furnace is a device that uses vacuum technology to heat alloy materials to a molten state in a highly vacuum environment; Currently, the traditional vacuum alloy melting furnace pours alloy materials into the inner cavity of the furnace, then seals it, and then drives a mechanical pump to extract the gas inside the furnace body to make its pressure reach the required vacuum degree. Then, it drives a heating element to make the materials in the furnace cavity reach the melting point, thereby completing the melting; However, in current industrial practices, the connection method between the mechanical pump and the furnace body mostly relies on a flange for fixed connection. However, under long-term exposure to high temperatures and various chemical and physical stresses generated during the melting process, the gasket inside the flange will age. Over time, the aged gasket can no longer provide an effective sealing effect. Especially in a working environment with a vacuum state, the gas inside the furnace body may leak out through these tiny gaps. Since gas leakage usually occurs in areas with poor sealing, and the gas flow in these areas is often very small, it is often difficult for operators to detect the leakage phenomenon in a timely manner. Without obvious visual or auditory cues, it is very difficult for operators to accurately judge the actual condition inside the furnace body, and thus they cannot adjust production parameters such as temperature, pressure, or gas flow in a timely manner according to the actual situation. This information asymmetry may lead to the accumulation of unstable factors during the production process, ultimately causing production interruptions or delays and affecting production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 10 As shown, the present invention provides a vacuum alloy melting furnace, comprising a base 1, a mounting plate 2 is fixedly installed on the top of the base 1, a driving device 3 is fixedly installed on one side of the mounting plate 2, a furnace body 4 is fixedly installed on the output end of the driving device 3, a furnace body 2 5 is arranged inside the furnace body 4, an exhaust pipe 6 is fixedly installed on one side of the outer surface of the furnace body 4, a mechanical pump 7 is arranged on the top of the base 1, an exhaust pipe 8 is fixedly installed on the output end of the mechanical pump 7, and flanges 9 are fixedly installed on one end of the exhaust pipe 6 and the exhaust pipe 8; A sealing assembly, which is arranged at the top of the base 1; An alarm mechanism is provided on the surface of the flange 9. The alarm mechanism includes a sealing sleeve 10 which is movably sleeved on the surface of the flange 9. At the bottom end of the outer surface of the sealing sleeve 10, a connecting pipe 11 is fixedly installed. One end of the connecting pipe 11 is fixedly installed with a housing 12. Inside the housing 12, an impeller 13 is rotatably connected. One end of the impeller 13 is fixedly installed with a cam 14. Inside the housing 12, a spring 15 is installed. One end of the spring 15 is fixedly installed with a sliding plate 16 located on one side of the cam 14. Inside the housing 12, a pressing plate 18 is fixedly installed. On the side of the sliding plate 16 close to the pressing plate 18, an impact plate 17 is fixedly installed.

[0019] Adopting the above solution: The operator puts the alloy material into the interior of the second furnace body 5, then connects the flanges 9 at one ends of the exhaust pipe 6 and the suction pipe 8 together. After the connection is completed, the sealing sleeve 10 can be sleeved on the surface of the flange 9, and then the sealing assembly is placed on the top of the first furnace body 4; Then, the mechanical pump 7 can be driven to extract the air inside the first furnace body 4 and the second furnace body 5 through the exhaust pipe 6 and the suction pipe 8. When the pressure inside the first furnace body 4 and the second furnace body 5 reaches the required vacuum degree, then the second furnace body 5 can be heated, and the temperature of the heating source is controlled so that the material inside the second furnace body 5 reaches the melting point; When the gasket between the two flanges 9 ages and leaks during long-term operation, the leaked gas will enter the interior of the sealing sleeve 10, and then the gas will enter the interior of the housing 12 along the connecting pipe 11. After the gas enters the interior of the housing 12, it will contact the fan blades on the surface of the impeller 13 and will push the impeller 13 to rotate. The impeller 13 will drive the cam 14 to rotate. During the rotation of the cam 14, its surface will contact the surface of the sliding plate 16 and will push the sliding plate 16 to move. When the sliding plate 16 moves, the spring 15 will be compressed. Then, due to the resilience of the spring 15, the sliding plate 16 will move reciprocally. The sliding plate 16 will drive the impact plate 17 to move. During the movement of the impact plate 17, it will strike the surface of the pressing plate 18 to make a sound, thereby warning the operator that the gas inside the first furnace body 4 leaks. Finally, the leaked gas pushes the impeller 13 to make the impact plate 17 strike the surface of the pressing plate 18 to issue an alarm, which can enable the operator to more accurately understand the gas state between the connections of the exhaust pipe 6 and the suction pipe 8, so as to timely adjust the production parameters and ensure the smooth progress of the smelting process. This helps to improve production efficiency and reduce production interruptions and delays caused by gas problems.

[0020] Such as Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, it further includes a rotating mechanism, which is arranged inside the first furnace body 4. The rotating mechanism includes a heating element 19. The heating element 19 is rotatably connected inside the first furnace body 4 and is designed around the surface of the second furnace body 5. A rotating rod 20 is fixedly installed at the bottom end of the heating element 19. A gear 21 is fixedly installed on the surface of the rotating rod 20. A rack 22 meshing with the gear 21 is slidably connected inside the first furnace body 4. A connecting ring 26 is fixedly installed at the bottom end of the rack 22. A telescopic cylinder 24 is fixedly installed inside the first furnace body 4. A swing rod 23 is rotatably connected inside the first furnace body 4, and one end of the swing rod 23 can slide inside the connecting ring 26. The output shaft of the telescopic cylinder 24 is fixedly installed with a hinge block 25 located on the surface of the swing rod 23, and the hinge block 25 is hinged to the swing rod 23.

[0021] With the above solution: Through the design of the rotating mechanism, after the first furnace body 4 is sealed, the heating element 19 can be driven, and then the heating element 19 can heat the surface of the second furnace body 5. During the heating process, the telescopic cylinder 24 can be driven to make its output shaft extend and retract. Then, the output shaft of the telescopic cylinder 24 will pull the hinge block 25 to move back and forth. Since the hinge block 25 is hinged to the swing rod 23, when the hinge block 25 moves, it can drive the swing rod 23 to rotate. One end of the swing rod 23 will slide inside the connecting ring 26. While sliding, it will drive the connecting ring 26 to move back and forth. The connecting ring 26 will drive the rack 22 to move back and forth inside the first furnace body 4. Because the rack 22 meshes with the gear 21, the reciprocating moving rack 22 can drive the gear 21 to rotate. The gear 21 will drive the rotating rod 20 to rotate. The rotating rod 20 will drive the pressing plate 18 to rotate back and forth. Finally, by driving the telescopic cylinder 24, the pressing plate 18 can rotate back and forth, so that the pressing plate 18 can cover a wider heating area and continuously change its position, thereby enabling all the alloy materials inside the second furnace body 5 to be evenly heated and improving its melting efficiency.

[0022] As Figure 2 and Figure 6 shown, the sealing assembly includes an electric push rod 31. The output shaft of the electric push rod 31 is fixedly installed with a sealing cover 32 located at the top of the first furnace body 4. The bottom end of the sealing cover 32 can be inserted into the first furnace body 4, and the surface of the sealing cover 32 is in contact with the inner wall of the first furnace body 4.

[0023] With the above solution: Through the design of the sealing assembly, after the alloy materials are added, the electric push rod 31 can be driven to make its output shaft pull the sealing cover 32 down. Then, the sealing cover 32 will contact the top of the first furnace body 4, and the bottom end of the sealing cover 32 will be inserted into the first furnace body 4. Since the surface of the sealing cover 32 is in contact with the inner wall of the first furnace body 4, the sealing effect of the first furnace body 4 can be ensured.

[0024] AsFigure 4 , Figure 9 and Figure 10 As shown in ,

[0025] , there is a fixing groove 27 inside the furnace body 1-4. A damping block 28 is fixedly installed inside the fixing groove 27. The number of damping blocks 28 is multiple, and the damping blocks 28 are arranged in an array inside the fixing groove 27. The surface of the damping block 28 is in contact with the surface of the rotating rod 20. Two support grooves 29 are opened on one side of the sealing sleeve 10. A support block 30 located inside the support groove 29 is fixedly installed on the side of the flange 9 close to the exhaust pipe 8. The support groove 29 and the support block 30 are designed to be longitudinally symmetric about the center of the exhaust pipe 8.

[0025] With the above scheme: Through the design of the fixing groove 27 and the damping block 28, since the surface of the damping block 28 is in contact with the surface of the rotating rod 20 and is arranged in an array inside the fixing groove 27, the damping effect of the rotating rod 20 can be increased, so that the heating element 19 and the rotating rod 20 rotate slowly, thereby improving the heating efficiency of the alloy material. Through the design of the support groove 29 and the support block 30, when the sealing sleeve 10 is sleeved on the surface of the flange 9, the support block 30 can be inserted into the support groove 29. Since the support groove 29 and the support block 30 are symmetrically designed, the sealing sleeve 10 can be supported to ensure that the leaked gas can smoothly enter the inside of the housing 12.

[0026] As Figure 1 and Figure 7 shown, a discharge pipe 36 is fixedly installed inside the furnace body 1-4 and the furnace body 2-5. Connecting strips 33 are fixedly installed on the surfaces of the furnace body 1-4 and the furnace body 2-5 on both sides of the discharge pipe 36. A plugging plate 34 is slidably connected inside the connecting strip 33. An electric push rod 2-35 is fixedly installed on one side of the outer surface of the furnace body 1-4, and the output shaft of the electric push rod 2-35 is fixedly connected to one side of the plugging plate 34.

[0027] With the above scheme: Through the design of the connecting strip 33, the plugging plate 34 and the electric push rod 2-35, after the alloy material is melted, the electric push rod 1-31 can be driven to move the sealing cover 32 away from the top of the furnace body 1-4. Then, the sealing sleeve 10 sleeved on the surface of the flange 9 can be removed. Then, the connecting parts on the surfaces of the two flanges 9 can be removed. Then, the device 3 can be driven to tilt the furnace body 1-4. During the tilting process, the mold can be placed at the bottom of the plugging plate 34. Then, the electric push rod 2-35 can be driven to make its output shaft pull the plugging plate 34 to slide inside the connecting strip 33. Then, the plugging plate 34 will cancel the plugging of the discharge pipe 36. Then, the molten alloy inside the furnace body 2-5 will flow from the discharge pipe 36 into the mold, thereby enabling the collection of the melted alloy.

[0028] As Figure 2 , Figure 6 and Figure 7As shown in the figure, a positioning plate 37 is fixedly installed on one side of the mounting plate 2 on the surface of the first furnace body 4. The positioning plate 37 is arc-shaped and its surface is fully attached to the first furnace body 4. An insulating plate 38 is fixedly installed inside the first furnace body 4. The insulating plate 38 is located at the top of the rotating mechanism, and the surface of the insulating plate 38 is attached to the inner wall of the first furnace body 4.

[0029] Adopting the above scheme: Through the design of the positioning plate 37, since the positioning plate 37 is arc-shaped and its surface is fully attached to the first furnace body 4, when the driving device 3 drives the first furnace body 4 to reset, the surface of the positioning plate 37 will contact the surface of the first furnace body 4, so that the positioning plate 37 can position the first furnace body 4. Through the design of the insulating plate 38, since the insulating plate 38 is arranged at the top of the rotating mechanism, it can isolate the temperature emitted by the heating element 19 and prevent the components of the rotating mechanism from being damaged by high temperature.

[0030] As Figure 4 、 Figure 6 and Figure 7 shown, the number of heating elements 19 is four, and they are arranged in an array inside the first furnace body 4. A gap is designed between the heating element 19 and the discharge pipe 36. The sealing sleeve 10 is made of rubber material, and the inner wall of the sealing sleeve 10 is fully attached to the surface of the flange 9. An air outlet is provided on one side of the housing 12.

[0031] Adopting the above scheme: Through the design of the heating element 19, since the number of heating elements 19 is four, the melting speed of the alloy material can be accelerated. And a gap is designed between the heating element 19 and the discharge pipe 36, so that when the heating element 19 rotates, the discharge pipe 36 will not interfere with the rotation of the heating element 19. Through the design of the sealing sleeve 10, since the sealing sleeve 10 is made of rubber material, it is convenient for the operator to put the sealing sleeve 10 on the surface of the flange 9. And an air outlet is provided on one side of the housing 12. After the leaked gas pushes the impeller 13 to rotate, it will be discharged from the inside of the air outlet.

[0032] The working principle and usage process of the present invention: First, the operator can pour the alloy material into the second furnace body 5. Then drive the first electric push rod 31 so that its output shaft pulls the sealing cover 32 to cover the top of the first furnace body 4, thereby sealing the first furnace body 4. Then the two flanges 9 can be connected together with bolts, and the sealing sleeve 10 can be put on the surface of the flange 9. At this time, the mechanical pump 7 can be driven to make the suction pipe 8 and the exhaust pipe 6 extract the air inside the first furnace body 4 to make the pressure inside reach the required vacuum degree; Next, the heating element 19 can be driven to heat the surface of the second furnace body 5. While heating, the telescopic cylinder 24 can be driven to extend and retract its output shaft. Then, the output shaft of the telescopic cylinder 24 will pull the hinge block 25 to move reciprocally. The hinge block 25 will drive the swing rod 23 to rotate. The rotating swing rod 23 will push the connecting ring 26 and the rack 22 to move reciprocally. The rack 22 will drive the gear 21, the rotating rod 20, and the heating element 19 to rotate reciprocally. Through the rotation of the heating element 19, the alloy material inside the second furnace body 5 can be evenly heated; When gas leakage occurs between the two flange plates 9 during long-term use of the equipment, the flowing gas will pass through the sealing sleeve 10 and the connecting pipe 11 and enter the interior of the housing 12. Then, the flowing gas will drive the impeller 13 to rotate. The impeller 13 will drive the cam 14 to rotate. The rotating cam 14 will contact the surface of the sliding plate 16 and push the sliding plate 16 to move. When the sliding plate 16 moves, the spring 15 will be compressed. Then, due to the resilience of the spring 15, the sliding plate 16 will move reciprocally. The sliding plate 16 will drive the impact plate 17 to strike the surface of the pressing plate 18 to make a sound, thereby warning the operator that gas leakage has occurred inside the first furnace body 4; After the alloy material is melted and refined, the electric push rod one 31 can be driven again to move the sealing cover 32 away from the top of the first furnace body 4. Then, the sealing sleeve 10 can be removed, and the connecting parts fixing the flange plates 9 can be removed. Next, the driving device 3 can be driven to tilt the first furnace body 4. Then, the mold can be placed at the bottom of the blocking plate 34. At this time, the electric push rod two 35 can be driven to pull its output shaft to make the blocking plate 34 slide inside the connecting bar 33. Then, the blocking of the discharge pipe 36 by the blocking plate 34 will be cancelled. Then, the alloy liquid inside the second furnace body 5 will flow into the mold from the discharge pipe 36, thereby being able to collect the melted and refined alloy, and finally completing the operation process.
