Description

Technical Field

[0001] The utility model relates to the technical field of metal refining equipment, in particular to a vacuum suspension smelting device. Background Art

[0002] A vacuum levitation melting furnace is an industrial device commonly used for smelting and refining metals. Its principle is to separate metals from non-metals by utilizing electromagnetic force and buoyancy under vacuum or protective gas conditions. The furnace operates by placing metal and non-metal materials into the furnace and melting them at high temperatures. Electromagnetic force and buoyancy are then applied to separate the metals and non-metals. The main components of a levitation melting furnace include the furnace body, induction coil, and magnets. The furnace body is typically made of specialized materials that can withstand high temperatures and corrosion. The induction coil generates electromagnetic force. Currenting the coil creates a magnetic field, which exerts force on the metal materials within the furnace. The magnets adjust the strength and direction of the magnetic field to separate the metals from the non-metals. By properly adjusting the magnetic field, the metals can be lifted upward, while the non-metals are pressed to the bottom of the furnace. Due to the density difference between the metals and non-metals, the metals can be separated from the bottom of the furnace by buoyancy. This allows the metals and non-metals to be collected and processed separately.

[0003] Suspension melting furnaces efficiently separate metals from non-metals, improving smelting and refining efficiency. Furthermore, due to the use of electromagnetic forces and buoyancy, they eliminate the need for mechanical devices, reducing energy and material consumption and lowering equipment maintenance costs. Furthermore, suspension melting furnaces can adapt to the smelting requirements of different materials, offering significant flexibility and adaptability. Therefore, they are of great significance to the development of the metals industry.

[0004] At present, the nozzles used to cool the molten metal in mature vacuum levitation melting devices are generally direct-injection nozzles fixed to the bottom. This results in the sprayed cooling gas being unable to surround the separated molten metal, resulting in poor cooling effect. Moreover, jetting from a single direction will disrupt the force balance of the alloy melt in the magnetic field, causing the suspended molten metal to collide with the induction copper beam during the actual smelting process, resulting in molten metal contamination, thereby affecting the cleanliness of the molten metal. To solve the above problems, the utility model provides a vacuum levitation melting device that can spray cooling gas from multiple directions to the separated molten metal, preventing the molten metal from being subjected to an unbalanced force in the magnetic field caused by jetting from a single direction, resulting in contact between the molten metal and the induction coil, causing molten metal contamination. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum suspension melting device to solve the problem that the molten metal is subjected to unbalanced force during cooling, causing the molten metal to collide with the induction copper beam and thus cause contamination of the molten metal.

[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a vacuum suspension smelting device, comprising a furnace body, a furnace door is provided on the furnace body, a first connecting rod is provided in the furnace body, the first connecting rod passes through the top of the furnace body, an induction copper bundle is fixedly connected to the furnace body, the other end of the first connecting rod is fixedly connected to a support rod, the other end of the support rod is fixedly connected to a covering nozzle, the covering nozzle surrounds the induction copper bundle, a plurality of nozzle holes are provided on the covering nozzle, and a gas source hole is provided on the covering nozzle.

[0007] The working principle of the utility model is that when it is necessary to cool the molten metal separated from the suspension smelting furnace, the gas source pipe is first connected to the gas source hole on the sheathed nozzle, and then the cooling gas is allowed to enter the sheathed nozzle through the gas source pipe. Then, the cooling gas is sprayed toward the middle from several nozzle holes on the sheathed nozzle to cool the molten metal in the induction copper bundle and turn it into a metal ingot.

[0008] The beneficial effect of the present invention is that the present invention realizes cooling of the molten metal without affecting the cleanliness of the molten metal by surrounding the outer side of the induction coil with a covering nozzle. Compared with the cooling nozzle of the suspension smelting furnace in the prior art, this design of the covering nozzle can spray cooling gas from multiple directions to cool the molten metal, which can effectively avoid the problem that the traditional cooling nozzle sprays cooling gas from a single direction, causing the molten metal to be subjected to unbalanced force, causing the molten metal to collide with the induction copper beam and thus affecting the cleanliness of the alloy melt.

[0009] Option 2 is a preferred option of the basic option. The induction copper bundle is a hollow coil. A water inlet pipe and a water outlet pipe are fixedly connected to the furnace body. One end of the induction copper bundle is connected to the water inlet pipe, and the other end of the induction copper bundle is connected to the water outlet pipe, which can cool the induction copper bundle.

[0010] Option three is the preferred option of the basic option. An observation window is provided on the furnace body to facilitate staff to observe the situation inside the furnace and facilitate operation.

[0011] Option 4 is the preferred option of the basic option. A second connecting rod is passed through the furnace body. The other end of the second connecting rod is fixedly connected to a connecting plate. The other end of the connecting plate is fixedly connected to a placement rack. The placement rack is located directly below the induction copper beam. The placement rack can be used to place the cooled alloy ingots.

[0012] Option 5 is a preferred option of the basic option. The first connecting rod and the second connecting rod are both provided with handles on one end that passes through the furnace body to facilitate operation by staff.

[0013] Option six is ​​the preferred option of the basic option. The cooling medium in the encapsulated nozzle is gas, and the gas is argon. Using gas as a cooling medium has better cooling function than liquid, and argon is inactive and has good stability. BRIEF DESCRIPTION OF THE DRAWINGS

The furnace body 1 is provided with a furnace door 2. One end of the first connecting rod 3 passes through the top of the furnace body 1. The furnace body 1 is fixedly connected with a water inlet pipe 9 and a water outlet pipe 10. The water inlet pipe 9 is connected with an induction copper bundle 4. The water outlet pipe 10 is connected with the other end of the induction copper bundle 4. The induction copper bundle 4 is a hollow coil. An observation window 11 is provided on the furnace body 1. The other end of the first connecting rod 3 is fixedly connected to a support rod 5. The other end of the support rod 5 is fixedly connected to a covering The cooling gas in the enclosed nozzle 6 is argon. The enclosed nozzle 6 surrounds the induction copper bundle 4. A plurality of nozzle holes 7 are provided on the enclosed nozzle 6. A gas source hole 8 is provided on the enclosed nozzle 6.

[0022] The implementation method of this embodiment is as follows: when it is necessary to cool the molten metal separated from the suspension smelting device, the staff first holds the handle 15 on the first connecting rod 3 and rotates the first connecting rod 3, so that the first connecting rod 3 drives the sheathed nozzle 6 on the support rod 5 to rotate, and the staff observes in the observation window 11. When the sheathed nozzle 6 moves to just below the induction copper bundle 4, the first connecting rod 3 is pulled upward, so that the first connecting rod 3 drives the sheathed nozzle 6 on the support rod 5 to move upward. When the staff observes from the observation window 11 that the sheathed nozzle 6 surrounds the induction copper bundle 4, another staff member opens the valve of the argon gas tank to allow the argon gas to pass through the gas source pipe and the gas source hole 8 into the sheathed nozzle 6. In the nozzle 6, argon gas is then sprayed toward the center through several nozzle holes 7 on the sheathed nozzle 6 to cool the molten metal. After cooling is completed, the valve of the gas tank is first closed. Then the staff member holds the handle 15 on the second connecting rod 12 and rotates the second connecting rod 12 so that the second connecting rod 12 drives the connecting plate 13 to rotate, thereby moving the placement rack 14 upward. Then the power of the induction copper beam 4 is turned off, and the cooled metal solution can fall onto the placement rack 14. Then the staff member rotates the second connecting rod 12 in the opposite direction again so that the second connecting rod 12 drives the connecting plate 13 to rotate, thereby moving the placement rack 14 downward. Finally, the staff member opens the furnace door 2 and uses a clamp to take out the metal ingot.
