Description

Technical Field

[0001] This utility model relates to the field of vacuum melting furnace technology, and specifically to a novel vacuum melting furnace. Background Technology

[0002] Currently, with the continuous development of synthetic materials, composite materials, and smart materials, the requirements for manufacturing processes and equipment are becoming increasingly stringent. In particular, vacuum melting equipment is widely used. A vacuum melting furnace is a type of vacuum melting equipment that can melt metals in a vacuum environment. During operation, due to differences in material properties and requirements, the timing and sequence of alloy material addition vary. During operation, multiple additions of materials are required according to the material preparation process. However, such multiple additions can easily disrupt the vacuum environment of the vacuum melting furnace, affecting the melting effect.

[0003] A search revealed that Chinese Patent CN217083283U discloses a novel multi-feeding mechanism for a vacuum melting furnace. This mechanism allows the guide trough to swing between the feeding and non-feeding positions above the melting crucible within the furnace chamber, avoiding the crucible. However, during operation, air remains in the gaps between the materials, which can enter the furnace chamber and affect metal melting. Furthermore, existing technologies use a method of adding a vacuum chamber for multi-feeding. First, the material is placed in the outer cavity of the feeding device, the valve connecting the outer cavity to the outside is closed, and then a vacuum is applied to the outer cavity to achieve a vacuum level similar to that of the vacuum melting furnace. Afterward, the valve between the outer cavity and the furnace is opened, allowing the material to enter the furnace. However, this method still suffers from the problem of air leakage between the materials.

[0004] To address the aforementioned problems, this utility model proposes a novel vacuum melting furnace. Utility Model Content

The output end of the winding motor drives the winding wheel to rotate, which in turn winds the pull rope, causing one end of the pull rope to move the slider downward until the sealing plug contacts the top rod. As the slider continues to move, under the action of the top rod, the sealing plug, sealing block and slider separate, exposing the material passage hole, so that the material falls from the material passage hole and enters the furnace body along the hose and bottom pipe, thus enabling the vacuum melting furnace to feed different materials multiple times.

[0035] The following is in conjunction with the appendix Figure 1-10 The present invention will be further illustrated by the embodiments:

[0036] like Figure 1-10As shown, a novel vacuum melting furnace is used for metal melting. During multiple feedings into the furnace body 1, air trapped between powdery materials prevents it from affecting the melting quality. The furnace body 1 includes a furnace body 1, a furnace cover 2 at one end, a vacuum pipe 3 connected to a vacuum pump fixedly connected to the surface of the furnace body 1, a heating assembly 4 fixedly connected inside the furnace body 1, a crucible 5 inside the furnace body 1, a support frame 6 fixedly connected to the surface of the furnace body 1, a feeding section 7 fixedly connected to the upper surface of the support frame 6, a feed pipe 8 connected to the feeding section 7 on the inner bottom wall of the support frame 6, the bottom end of the feed pipe 8 extending to the furnace body 1 and facing the crucible 5, an inlet pipe 9 for injecting inert gas fixedly connected to the surface of the feed pipe 8, a one-way valve 10 at the top of the feeding section 7, and a distribution plate 11 fixedly connected to the bottom end of the feed pipe 8 for dispersing materials into the crucible 5.

[0037] Specifically, by setting up an air inlet pipe 9 to connect with an external inert gas supply device, inert gas is passed into the feed pipe 8. The inert gas compresses the air present in the material gaps and discharges it through the one-way valve 10 to the feeding section 7, thus preventing the air present in the material gaps from affecting the melting quality. This allows the vacuum melting furnace to reduce the impact of air in the material gaps on the melting quality. The inert gas is preferably nitrogen. It is connected to an external vacuum pump through a vacuum pipe 3 to create a vacuum environment inside the furnace body 1.

[0038] The distributing tray 11 includes a conical tray 111. Several distributing grooves 112 are respectively opened on the surface of the tray 111. The distributing grooves 112 are evenly arranged in a circumferential array on the surface of the tray 111. By setting the distributing tray 11, the material can be dispersed into the crucible 5 from different positions, preventing the molten liquid in the crucible 5 from splashing due to a large amount of material being added from one position. By setting the distributing grooves 112, the material is dispersed into several distributing grooves 112 before falling into the crucible 5, preventing the phenomenon of molten liquid splashing.

[0039] The inner bottom wall of the support frame 6 is provided with a sliding groove, and a connecting seat 12 is slidably connected to the inner wall of the sliding groove. The connecting seat 12 is right-angled. One end of the connecting seat 12 is fixedly connected to the feed pipe 8. A vibration spring 13 is fixedly connected to the outer side of the connecting seat 12. The other end of the vibration spring 13 is fixedly connected to the inner wall of the sliding groove. A driving part is fixedly connected to the inner bottom wall of the support frame 6. The driving part is used to drive the feed pipe 8 to vibrate to prevent the material from clumping.

The vibration motor 16 drives the eccentric block 15 to rotate, intermittently pushing the corresponding connecting seat 12. By setting the drive unit to intermittently push the corresponding connecting seat 12 to move, the feed pipe 8 is moved. With the cooperation of the vibration spring 13, the feed pipe 8 vibrates, so as to remove the clumps of material in the feed pipe 8. The material is broken up to prevent it from clumping, which in turn prevents clumped material from falling into the molten liquid and causing splashing. This gives the vacuum melting furnace the effect of preventing molten liquid splashing. The output end of the vibration motor 16 drives the eccentric block 15 to rotate, which in turn drives the corresponding connecting seat 12 to move. In turn, with the cooperation of the vibration spring 13, the feed pipe 8 vibrates, which changes the gap between the materials. This helps to open up the originally relatively closed small space, making it easier for inert gas to enter these gaps, releasing and expelling the air between the materials, and improving the air replacement effect.

By setting the hose 802, vibration is prevented from being transmitted to the bottom pipe 803 and affecting the stability of the furnace body 1.

[0042] The feeding unit 7 includes a feeding box 701. A rotating shaft 702 is rotatably connected to the inner bottom wall of the feeding box 701. Several partitions 703 are fixedly connected to the surface of the rotating shaft 702.

The feeding port 706 is connected to the feeding pipe 8, and the inner diameter of the feeding port 706 is smaller than the inner diameter of the feeding pipe 8. A rotary motor 704 is fixedly connected to the inner bottom wall of the support frame 6. The output end of 04 is fixedly connected to the rotating shaft 702. The upper surface of the feed box 701 is detachably connected to the box cover 705. The one-way valve 10 is installed on the upper surface of the box cover 705. The output end of the rotating motor 704 drives the rotating shaft 702 to rotate, which in turn drives the partition 703 to rotate, so that the material stored in the adjacent partition 703 can be sent to the feed port 706. By setting the detachable box cover 705, it is convenient to put materials into the feed box 701.

[0043] A slider 17 is slidably connected to the inner wall of the feed pipe 8. A feed hole 18 is formed on the upper surface of the slider 17. A sealing plug 19 is provided in the feed hole 18. A sealing block 20 for closing the feed inlet 706 is fixedly connected to the upper surface of the sealing plug 19. An inclined surface 21 is formed on the inner wall of the feed hole 18, penetrating the upper surface of the slider 17. An installation groove is formed on the inclined surface 21, and an end seat 22 is fixedly connected to the inner wall of the installation groove. The top of the end seat 22 is flush with the inclined surface 21. A sliding base 23 is slidably connected to the inner wall of the installation groove. A sliding rod 24 is fixedly connected to the upper surface of 23. The top end of the sliding rod 24 passes through the end seat 22 and is fixedly connected to a connecting block 25. The connecting block 25 is fixedly connected to the sealing plug 19. A tension spring 26 is sleeved on the surface of the sliding rod 24. The bottom end of the tension spring 26 is fixedly connected to the sliding base 23, and the top end of the tension spring 26 is fixedly connected to the end seat 22. A top rod 27 is fixedly connected to the top end of the distributing plate 11. By setting the slider 17, the sealing plug 19 and the sealing block 20, the feed port 706 can be closed so that the target material can be fed.

[0044] A limiting block 28 is fixedly connected to the inner wall of the jacking pipe 801. A through hole is formed on the upper surface of the limiting block 28, and the inner wall of the through hole is arc-shaped. A pull rope 29 is fixedly connected to the bottom of the sealing plug 19. The bottom end of the pull rope 29 passes through the through hole and through the surface of the jacking pipe 801. A support plate 30 is fixedly connected to the bottom of the connecting seat 12. A winding wheel 31 is rotatably connected to the back of the support plate 30. One end of the pull rope 29 is fixedly connected to the winding wheel 31. A winding motor 32 is fixedly connected to the front of the support plate 30. The output end of the winding motor 32 is fixedly connected to the winding wheel 31. A return spring 33 is sleeved on the surface of the pull rope 29. The top end of the spring 33 is fixedly connected to the sealing plug 19, and the bottom end of the return spring 33 is fixedly connected to the limiting block 28. The output end of the winding motor 32 drives the winding wheel 31 to rotate, thereby winding the pull rope 29. This causes one end of the pull rope 29 to drive the slider 17 to move downward until the sealing plug 19 contacts the top rod 27. As the slider 17 continues to move, under the action of the top rod 27, the sealing plug 19, the sealing block 20 and the slider 17 are separated, exposing the material passage hole 18 so that the material falls from the material passage hole 18 and enters the furnace body 1 along the hose 802 and the bottom pipe 803, thereby allowing the vacuum melting furnace to feed different materials multiple times.

[0045] A support base 34 is fixedly connected to the inner bottom wall of the furnace body 1. A guide rail 35 is fixedly connected to the upper surface of the support base 34. A movable plate 36 is slidably connected to the upper surface of the guide rail 35. A limit ring 37 is fixedly connected to the upper surface of the movable plate 36. The crucible 5 is placed inside the limit ring 37. By setting the guide rail 35 and the movable plate 36, it is convenient to put the crucible 5 into the furnace body 1.

[0046] Working principle: When using this vacuum melting furnace, first push the moving plate 36 to place the crucible 5 into the furnace body 1, then close the furnace cover 2, and start the external vacuum pump to create a vacuum environment in the furnace body 1 and the feed pipe 8. Then, pour the material into the space formed by the two adjacent partitions 703 in the feed box 701, then close the box cover 705, and start the heating component 4 to melt the metal. When additional material is needed, start the rotary motor 704. The rotary motor 704 drives the rotating shaft 702 to rotate, and the rotating shaft 702 drives the partitions 703 to rotate, thus adding the corresponding material. The material is moved to the position corresponding to the feed inlet 706, and then the winding motor 32, the vibrating motor 16, and the external inert gas injection equipment are started. The output end of the winding motor 32 drives the winding wheel 31 to rotate, and the winding wheel 31 winds up the pull rope 29. One end of the pull rope 29 drives the slider 17 to move downward until the sealing plug 19 contacts the top rod 27. As the slider 17 continues to move, under the action of the top rod 27, the sealing plug 19 and the sealing block 20 are separated from the slider 17, exposing the material passage hole 18. The material falls from the material passage hole 18 through the feed inlet 706 and along... The material flows through the hose 802 and the bottom pipe 803. When it reaches the distribution plate 11, the distribution trough 112 disperses the material from different positions into the crucible 5, preventing the molten liquid in the crucible 5 from splashing due to a large amount of material being added from one position. The air inlet pipe 9 passes inert gas into the feed pipe 8. The inert gas compresses the air present in the gaps between the materials and discharges it through the one-way valve 10 to the feeding section 7, preventing the air present in the gaps between the materials from affecting the melting quality. At the same time, the rotary motor 704 drives the eccentric block 15 to rotate. The rotation of the eccentric block 15 pushes the corresponding connecting seat 12 to move, thereby vibrating the spring. With the cooperation of spring 13, the feed pipe 8 vibrates. On the one hand, it breaks up the clumps of material in the feed pipe 8, preventing them from clumping together and thus preventing them from falling into the molten liquid and causing splashing. On the other hand, the vibration of the feed pipe 8 changes the gaps between the materials, which helps to open up the originally relatively closed small spaces, making it easier for inert gas to enter these gaps, releasing the air between the materials and improving the air replacement effect. Other materials are added into the furnace body 1 in the same way, so that the vacuum melting furnace can reduce the impact of air in the gaps between materials on the melting quality.
