Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum induction melting furnace technology, and specifically to a vacuum induction melting furnace. Background Technology
[0002] Vacuum induction melting furnace is a high-precision metallurgical equipment that melts metals using the principle of electromagnetic induction heating in a vacuum or inert gas environment. It mainly consists of a vacuum system, induction coil, refractory crucible and computer control system. The equipment uses a high-frequency alternating magnetic field to induce eddy current heating and melt the metal material. It can effectively avoid air pollution and accurately control the alloy composition. It is particularly suitable for the purification and precision casting of high-value-added metals such as titanium alloys, high-temperature alloys and magnetic materials. It is widely used in high-end manufacturing fields such as aerospace, nuclear power and medical devices. It has significant advantages such as uniform composition, low gas content and few inclusions.
[0003] However, the waste gas generated during the use of existing vacuum induction melting furnaces is directly emitted into the atmosphere, which leads to air pollution and affects the surrounding air environment. To address this, we propose a vacuum induction melting furnace. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vacuum induction melting furnace to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution:
[0006] A vacuum induction melting furnace includes a furnace body, a fixed base fixedly connected to the bottom of the furnace body, a heat recovery component fixedly connected to the top of the furnace body, filter boxes fixedly connected to the top of the furnace body and on both sides of the heat recovery component, a recovery conversion box fixedly connected to the top of the heat recovery component, and a battery fixedly connected to the top of the recovery conversion box. The filter boxes and activated carbon balls facilitate the filtration of exhaust gas, preventing the release of toxic gases that could pollute the environment and surrounding working conditions. Simultaneously, the unidirectional air inlet core at the top of the filter box allows the exhaust gas inside the filter box to be cooled by external air, preventing damage to the filter box due to excessive temperature.
[0007] Furthermore, the heat recovery assembly has a recovery cavity inside, an air inlet at the bottom, and exhaust pipes on both sides of the heat recovery assembly where they connect to the filter box. A sealing plug is movably fitted inside the recovery cavity, and a spring is movably connected to the top of the sealing plug.
[0008] Furthermore, support rods are fixedly connected to both sides of the bottom of the sealing plug, and a telescopic rod is fixedly connected to the top of the sealing plug and the middle of the spring. A rack rod is fixedly connected to the top of the telescopic rod. The rack rod is located inside the recycling conversion box, and gear sets are driven to both sides of the rack rod. The gear sets are movably sleeved inside the recycling conversion box. By providing a heat recovery component and a recycling conversion box, it is beneficial to convert the waste gas discharged from the vacuum induction melting furnace body, thereby causing the sealing plug to move up and down. This causes the gear sets inside the recycling conversion box to drive the electromagnetic component to rotate, thereby causing the electromagnetic component to convert the waste gas into electrical energy for recovery.
[0009] Furthermore, the recycling conversion box has an internal cavity located at the position of the movable connecting gear set, and electromagnetic components are fixedly sleeved inside the gear set.
[0010] Furthermore, the filter box is equipped with regularly arranged activated carbon balls.
[0011] Furthermore, the filter box has regularly arranged exhaust slots on the surface away from the heat recovery component, and circular through holes are provided on the surface of the filter box near the heat recovery component.
[0012] Furthermore, a one-way air intake core is movably connected to the top of the filter box, and an arc-shaped baffle is provided on one side of the bottom of the movably connected one-way air intake core in the filter box.
[0013] Furthermore, the gear set meshes with the rack rod fixedly connected to the top of the telescopic rod.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model, by incorporating a filter box and activated carbon balls, facilitates the filtration of exhaust gas, preventing the release of toxic gases that could pollute the environment and surrounding working conditions. Simultaneously, the one-way air intake core at the top of the filter box allows the exhaust gas inside to be cooled by external air, preventing damage to the filter box due to excessively high temperatures.
[0016] 2. This utility model, by providing a heat recovery component and a recovery conversion box, facilitates the conversion of the waste gas discharged from the vacuum induction melting furnace body, thereby causing the sealing plug to move up and down, which in turn causes the gear set inside the recovery conversion box to drive the electromagnetic component to rotate, thereby enabling the electromagnetic component to convert the waste gas into electrical energy for recovery.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] Reference Figures 1-5 As shown, this utility model provides a vacuum induction melting furnace, including a vacuum induction melting furnace body 1, a fixed base 2 fixedly connected to the bottom of the vacuum induction melting furnace body 1, a heat recovery component 3 fixedly connected to the top of the vacuum induction melting furnace body 1, filter boxes 4 fixedly connected to the top of the vacuum induction melting furnace body 1 and on both sides of the heat recovery component 3, a recovery conversion box 5 fixedly connected to the top of the heat recovery component 3, and a storage battery 6 fixedly connected to the top of the recovery conversion box 5. By providing filter boxes 4 and activated carbon balls 10, it is beneficial to filter the exhaust gas to prevent the release of toxic gases from polluting the environment and the surrounding working environment. At the same time, through the one-way air inlet core 11 at the top of the filter box 4, the exhaust gas inside the filter box 4 is cooled by the outside air, preventing the filter box 4 from being damaged by excessively high temperature.
[0028] The heat recovery component 3 has a recovery cavity 301 inside, an air inlet 303 at the bottom, and exhaust pipes 302 on both sides of the heat recovery component 3 where it connects to the filter box 4. A sealing plug 7 is movably fitted inside the recovery cavity 301, and a spring 8 is movably connected to the top of the sealing plug 7.
[0029] The sealing plug 7 has support rods 701 fixedly connected to both sides of its bottom. A telescopic rod 702 is fixedly connected to the top of the sealing plug 7 and to the middle of the spring 8. A rack rod 703 is fixedly connected to the top of the telescopic rod 702. The rack rod 703 is located inside the recycling conversion box 5. Gear sets 9 are driven to both sides of the surface of the rack rod 703. The gear sets 9 are movably sleeved inside the recycling conversion box 5. With the heat recovery component 3 and the recycling conversion box 5, the exhaust gas discharged from the vacuum induction melting furnace body 1 is converted, which causes the sealing plug 7 to move up and down. This causes the gear sets 9 inside the recycling conversion box 5 to drive the electromagnetic component 10 to rotate, which in turn causes the electromagnetic component 10 to convert the exhaust gas into electrical energy for recovery.
[0030] The recycling conversion box 5 has an inner cavity 501 located at the position of the movable connecting gear set 9, and the electromagnetic component 10 is fixedly sleeved inside the gear set 9.
[0031] The filter box 4 has a regularly arranged set of activated carbon balls 12 inside.
[0032] The filter box 4 has regularly arranged exhaust slots 401 on the surface away from the heat recovery component 3, and circular through holes 402 on the surface of the filter box 4 near the heat recovery component 3.
[0033] Among them, a one-way air intake core 11 is movably connected to the top of the filter box 4, and an arc baffle 403 is provided on the bottom side of the filter box 4 where the one-way air intake core 11 is movably connected.
[0034] Among them, the gear set 9 meshes with the rack rod 703 fixedly connected to the top of the telescopic rod 702.
[0035] The working principle of this utility model:
[0036] First, when the vacuum induction melting furnace body 1 is operating and generating exhaust gas, the high-temperature exhaust gas inside the vacuum induction melting furnace body 1 enters the recovery inner cavity 301 through the air inlet 303. Then, the high-temperature exhaust gas pushes the sealing plug 7 upward. At this time, the rising of the sealing plug 7 compresses the spring 8. Then, the sealing plug 7 drives the telescopic rod 702 and the rack rod 703 to rise. Then, the rising of the rack rod 703 drives the gear set 9 inside the inner cavity 501 of the recovery conversion box 5 to rotate. Then, the rotation of the gear set 9 causes the electromagnetic component 10 to generate electrical energy. Electrical energy is stored in the battery 6 at the top of the heat recovery conversion box 5. Then, when the sealing plug 7 is lifted to the position of the exhaust pipe 302 on both sides of the surface of the heat recovery component 3, the high temperature exhaust gas enters the circular through hole 402 of the filter box 4 through the exhaust pipe 302. At this time, the sealing plug 7 is lowered due to the pressure of the gas. At this time, the spring 8 pushes the sealing plug 7 to fall. At this time, the exhaust pipe 302 no longer discharges exhaust gas. Then, when the sealing plug 7 falls, it drives the rack rod 703 to fall, which in turn drives the gear set 9 to rotate again. At this time, the electromagnetic component 10 generates electrical energy again due to rotation and sends it to the battery 6 for storage.
[0037] The exhaust gas entering the circular through-hole 402 is then filtered and adsorbed by the activated carbon balls 12, which adsorbs and filters particulate dust and toxic gases in the exhaust gas. The filtered exhaust gas is then discharged through the exhaust slot 401. At the same time as the exhaust gas is discharged, the airflow inside the filter box 4 creates a certain negative pressure inside the filter box 4. The one-way air inlet core 11 is then driven to flip to the other side of the arc-shaped baffle 403, allowing outside air to enter the filter box 4. The exhaust gas inside the filter box 4 is then cooled. The cooled exhaust gas then enters and exits through the exhaust slot 401. This process is repeated to allow the heat energy inside the exhaust gas to be utilized to generate electricity during the filtration and purification process, thereby achieving the purpose of protecting the environment and saving energy.
[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
