Description

Technical Field

[0001] The invention relates to the technical field of stirring furnaces, and in particular to an ultra-high temperature corrosion-resistant vacuum heating stirring furnace. Background Art

[0002] A furnace is an appliance that can heat and melt objects. It is widely used in industries such as industry, laboratories, and smelting. In smelting and other industries, the furnace is the main equipment used to melt materials. It can melt ores and other materials by heating and reducing them. Furnaces are generally divided into two types: external heating and internal heating. External heating furnaces heat internal materials through external heat sources, while internal heating furnaces use chemical reactions inside the materials to generate heat to melt them.

[0003] Common stirring furnaces are generally heated by electromagnetic heating. Due to the electromagnetic heating method, it is difficult to accurately control the heating and cooling curves. At the same time, when the stirring furnace is smelting corrosive materials, the corrosive substances may corrode the furnace wall, agitator and other components during the mixing process with the charge, which will cause material loss and equipment damage. In addition, some corrosive substances will decompose or release harmful gases at high temperatures.

[0082] The following will be combined with 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.

[0083] like Figures 1 to 12As shown, this embodiment proposes an ultra-high temperature corrosion-resistant vacuum heating stirring furnace, including a furnace body 1, a cover plate 2 is detachably installed on the top of the furnace body 1, and also includes a furnace cover 3, a kettle cover lining 4, an insulation component, a reactor 5, a gas protection component, an exhaust component, a heating component and a stirring component. The furnace cover 3 is detachably installed on the top of the cover plate 2, and the kettle cover lining 4 is fixedly installed on the bottom of the furnace cover 3. The insulation component is installed inside the furnace body 1 for insulation. The insulation component includes a sealing ring 6, an anti-corrosion smoke retaining ring 7, a mounting ring 8 and an anti-corrosion smoke guide ring 9 The sealing ring 6 is fixedly installed on the top of the cover plate 2, and the upper part of the sealing ring 6 abuts against the kettle cover lining 4. The anti-corrosion smoke retaining ring 7 is fixedly installed inside the furnace body 1, and the top of the anti-corrosion smoke retaining ring 7 abuts against the kettle cover lining 4. The mounting ring 8 is fixedly installed inside the furnace body 1, and the mounting ring 8 is located and abuts against the anti-corrosion smoke retaining ring 7. The reactor 5 is arranged in the mounting ring 8, wherein the outer edge of the reactor 5 abuts against the top of the mounting ring 8, and the anti-corrosion smoke guide ring 9 is detachably installed on the anti-corrosion smoke retaining ring 7, and the bottom of the anti-corrosion smoke guide ring 9 abuts against the reactor 5.

[0084] Specifically, when it is necessary to melt the materials, first put the materials into the reactor 5. These materials can be metals, non-metals, compounds or other substances, depending on the final product to be produced. At this time, the driving device is connected to the stirring component, and the materials are stirred by the stirring component to make them evenly mixed. The stirring speed and time can be adjusted as needed. When the raw materials are fully mixed, start the heating component to heat them to an appropriate temperature until the materials are completely melted. The setting of the insulation component can avoid heat loss. At this time, the exhaust component can also be set to make the inside of the reactor 5 in a vacuum state. Since the inside of the reactor 5 is in a vacuum state and is not affected by atmospheric pressure, it can withstand higher temperatures, reduce the generation of oxides, reduce oxidation losses, and help prevent impurity contamination and improve product purity. After the smelting is completed, the finished product can be discharged into the next link.

[0085] It should be added that if the material smelted in the reactor 5 is corrosive, the anti-corrosion flue gas guide ring 9, the anti-corrosion flue gas retaining ring 7 and the sealing ring 6 are provided, and two sealing rings 6 are provided, so that the sealing is improved, and the corrosive flue gas generated in the reaction process can be introduced into the exhaust component and then discharged outside the furnace body 1.

[0086] like Figure 5 , Figure 6 As shown, the reactor 5 is installed inside the insulation component, and the gas protection component is installed inside the insulation component for protecting the equipment. The gas protection component includes a fixed ring 10, a support ring 11, an annular pipe 12 and an exhaust part. The fixed ring 10 is fixedly installed on the inner bottom wall of the furnace body 1, the support ring 11 is fixedly installed on the top of the fixed ring 10, the annular pipe 12 is fixedly installed on the fixed ring 10, and the exhaust part is installed on the annular pipe 12 for discharging inert gas.

[0087] Specifically, in order to reduce the influence of the corrosive gas generated during the reaction of the reactor 5 on the heating wire 23, the gas source is connected to the annular tube 12, and the inert gas is filled into the annular tube 12. Through the setting of the exhaust part, the inert gas is sent into the gap between the insulation tube 20 and the reactor 5 to form an inert gas protective layer to prevent the heating wire 23 from being damaged by contacting the corrosive gas.

[0088] It should be added that the structures such as the anti-corrosion smoke retaining ring 7, the mounting ring 8, the anti-corrosion smoke guide ring 9, the fixing ring 10, the supporting ring 11, etc. are all treated with anti-corrosion.

[0089] The above, such as Figure 6 As shown, the exhaust part includes an air intake heating device 13, which is fixedly mounted on the furnace body 1, and also includes an air intake pipe 14 and a diffuser 15. The air intake pipe 14 is connected to the annular pipe 12; the air intake pipe 14 is located inside the air intake heating device 13, and the annular pipe 12 is connected with a plurality of diffusers 15 at equal angles in a circular shape, and the top end of the diffuser 15 is fixedly mounted on the support ring 11.

[0090] Specifically, when the inert gas is filled into the air between the insulation tube 20 and the reactor 5, the gas source is connected to the air inlet pipe 14, the inert gas enters the annular tube 12 through the air inlet pipe 14, and finally enters between the insulation tube 20 and the reactor 5 through the setting of the diffuser 15 to protect the heating wire 23. In this process, the air intake heating device 13 is started, and the appropriate inert gas and temperature range are selected according to the specific application situation to ensure the best protection effect.

[0091] It should be added that the temperature of the inert gas is an important factor. Generally, as the temperature increases, the solubility of the gas increases, that is, at a higher temperature, a lower concentration of inert gas can be used to achieve the same protective effect, making the protective effect better.

[0092] like Figure 4 , Figure 5 As shown, the exhaust assembly is installed on the furnace cover 3 for exhausting gas and adding materials. The exhaust assembly includes a peephole 16, a feeding port 17, a smoke exhaust pipe 18 and a vacuum port 19. The peephole 16 is opened on the top of the furnace cover 3, the feeding port 17 is opened on the top of the furnace cover 3, the smoke exhaust pipe 18 is fixedly installed on the top of the furnace cover 3, the smoke exhaust pipe 18 is connected to the furnace cover 3, and the vacuum port 19 is fixedly installed on the top of the furnace cover 3.

[0093] Specifically, during the reaction process, the reaction situation can be observed through the setting of the peephole 16. When vacuuming, the equipment is connected to the vacuum port 19, and the smoke exhaust pipe 18 and the feeding port 17 are sealed, and vacuuming can be started. When the corrosive gas is discharged, it will be discharged through the smoke exhaust port.

[0094] like Figure 5 , Figure 7 As shown, the heating component is installed on the furnace body 1 and is used to heat the reactor 5. The heating component includes an insulation tube 20, a mounting groove 21, a junction box 22, an electric heating wire 23, a sensor 24 and a discharge part. The insulation tube 20 is fixedly installed between the support ring 11 and the mounting ring 8. The insulation tube 20 is set to an aluminum silicate material, wherein the outlet of the diffuser 15 is located in the gap between the insulation tube 20 and the reactor 5. A mounting groove 21 is opened inside the insulation tube 20. The junction box 22 is fixedly installed on the furnace body 1. The electric heating wire 23 is fixedly installed inside the mounting groove 21. The electric heating wire 23 is electrically connected to the junction box 22. A plurality of sensors 24 are fixedly installed at equal distances on the furnace body 1. The working end of the sensor 24 is connected to the insulation tube 20. The discharge part is installed at the bottom of the furnace body 1 for discharging.

[0095] Specifically, during the heating process, the material in the reactor 5 is heated by the setting of the junction box 22 using the heating wire 23. During the heating process, the temperature of the reactor 5 is monitored by the setting of the sensor 24, thereby forming a furnace temperature closed-loop control with the heating wire 23 and the electrical control components. By calculating and comparing the data of multiple sensors 24, the heating and cooling curves in the reactor 5 are accurately controlled to meet the material's requirements for the heating and cooling process.

[0096] The above, such as Figure 8 As shown, the discharge part includes a valve body heater 25, a discharge valve 26, a discharge pipe 27 and a pipe heater 28. The valve body heater 25 is fixedly installed on the inner bottom wall of the furnace body 1, and the valve body heater 25 is located inside the fixing ring 10. The discharge valve 26 is fixedly installed on the bottom of the reactor 5. The input end of the discharge valve 26 is connected with the bottom of the reactor 5. The discharge valve 26 is located inside the valve body heater 25. The discharge pipe 27 is fixedly installed on the bottom of the furnace body 1. The discharge pipe 27 is connected with the output end of the discharge valve 26. The pipe heater 28 is fixedly installed on the discharge pipe 27.

[0097] Specifically, after the reaction is completed, the material in the reactor 5 needs to be discharged. At this time, the discharge valve 26 is opened to allow the material in the reactor 5 to flow into the discharge pipe 27 and then be sent to the storage position. During this process, the valve body heater 25 and the pipe heater 28 are turned on to keep the discharge pipe 27 and the discharge valve 26 higher than the ambient temperature, which is conducive to the discharge of the material.

[0098] like Figures 9 to 12As shown, the stirring assembly is installed on the furnace cover 3 for stirring. The stirring assembly includes a stirring shaft 29, a transmission shaft 30, a stirring frame 31 and a connecting portion. The stirring shaft 29 is rotatably installed on the furnace cover 3, the transmission shaft 30 is arranged at the lower part of the stirring shaft 29, and the stirring frame 31 is fixedly installed at the bottom of the transmission shaft 30. The stirring frame 31 is in sliding contact with the inner wall of the reactor 5, and the connecting portion is installed at the lower part of the stirring shaft 29 for connecting the transmission shaft 30.

[0099] Specifically, during the stirring process, the stirring shaft 29 is connected to the driving device to drive the stirring shaft 29 to stir. The stirring shaft 29 drives the transmission shaft 30 to rotate through the setting of the connecting part, thereby driving the stirring frame 31 to rotate, and the material in the reactor 5 can be stirred.

[0100] The above, such as Figures 9 to 12 As shown, the connection portion includes a connecting tube 32, a slide groove 33, a guide groove 34, a slider 35 and an arc groove 36. The upper and lower ends of the connecting tube 32 are respectively slidably matched with the stirring shaft 29 and the transmission shaft 30. The bottom end of the stirring shaft 29 and the top end of the transmission shaft 30 are both circularly provided with a plurality of slide grooves 33 at equal angles. Guide grooves 34 are provided on both sides of each slide groove 33. A slider 35 is slidably installed on each slide groove 33. The slider 35 is slidably matched with the guide groove 34. The connecting tube 32 is provided with a plurality of slide grooves 33. The upper and lower sides of the part are provided with a plurality of arc grooves 36 at equal angles in a circular shape, and the plurality of arc grooves 36 correspond one-to-one to the plurality of sliders 35. The part also includes a positioning block 37, a plug-in groove 38 and a conical block 39. The positioning block 37 is fixedly installed inside the connecting cylinder 32, and the bottom of the stirring shaft 29 and the top of the transmission shaft 30 are provided with a plug-in groove 38. Conical blocks 39 are fixedly installed at the upper and lower ends of the positioning block 37, and the conical block 39 is adapted to the plug-in groove 38, and the conical block 39 abuts against the slider 35.

[0101] Specifically, when the stirring shaft 29 and the transmission shaft 30 are connected, the bottom of the stirring shaft 29 and the top of the transmission shaft 30 are respectively inserted into the connecting tube 32. At this time, the slider 35 is located in the slide groove 33. As the stirring shaft 29 and the transmission shaft 30 move, the plug-in groove 38 moves toward the direction of the positioning block 37. Through the setting of the tapered block 39, when the slider 35 contacts the tapered block 39, the slider 35 moves in the slide groove 33 along the guide groove 34 until the slider 35 moves into the arc groove 36, and the stirring shaft can be connected. 29 and the transmission shaft 30 are installed in place. During the rotation of the stirring shaft 29, the stirring shaft 29 drives the transmission shaft 30 to rotate through the connecting tube 32 through the cooperation of the slider 35 and the arc groove 36. There is a certain gap between the slider 35 and the arc groove 36, and there is a certain space during the reaction process, which can reduce the influence of the high temperature during the reaction process on the connection between the stirring shaft 29 and the transmission shaft 30, improve the quality of the connection and the stability during stirring, and the stirring shaft 29, the mixer and the transmission shaft 30 are all treated with corrosion protection.

[0102] To sum up, when it is necessary to melt the material, first put the material into the reactor 5 through the feeding port 17. These materials can be metals, non-metals, compounds or other substances, depending on the final product to be produced. At this time, the driving device is connected to the stirring shaft 29. The stirring shaft 29 drives the transmission shaft 30 to rotate through the connecting tube 32 through the cooperation of the slider 35 and the arc groove 36. There is a certain gap between the slider 35 and the arc groove 36, and there is a certain space during the reaction process, which can reduce the influence of the high temperature during the reaction process on the connection between the stirring shaft 29 and the transmission shaft 30, improve the quality of the connection and the stability during stirring, stir the material to make it evenly mixed, and the stirring speed and time can be adjusted as needed.

[0103] After the raw materials are fully mixed, they need to be heated to an appropriate temperature. Through the setting of the junction box 22, the heating wire 23 is used to heat the materials in the reactor 5. During the heating process, the temperature of the reactor 5 is monitored through the setting of the sensor 24, thereby forming a furnace temperature closed-loop control with the heating wire 23 and the electrical control components. Through the calculation and comparison of the data of multiple sensors 24, the heating and cooling curves in the reactor 5 are accurately controlled to meet the material's requirements for the heating and cooling process until the material is completely melted. The setting of the insulation component can avoid heat loss. At this time, the equipment is connected to the vacuum port 19, and the exhaust pipe 18 and the feeding port 17 are sealed, and vacuuming can be started to put the inside of the reactor 5 in a vacuum state. Since the inside of the reactor 5 is in a vacuum state, there is no influence of atmospheric pressure, so it can withstand higher temperatures, and reduces the generation of oxides, reduces oxidation losses, and helps to prevent impurity contamination and improve product purity.

[0104] In order to reduce the influence of the corrosive gas generated during the reaction of the reactor 5 on the heating wire 23, the gas source is connected to the air inlet pipe 14, and the inert gas enters the annular tube 12 through the air inlet pipe 14, and finally enters between the insulation tube 20 and the reactor 5 through the setting of the diffuser 15, forming an inert gas protection layer to prevent the heating wire 23 from being damaged by contact with the corrosive gas, thereby protecting the heating wire 23. In this process, the air intake heating device 13 is started, and the appropriate inert gas and temperature range are selected according to the specific application to ensure the best protection effect.

[0105] After the reaction is completed, the material in the reactor 5 needs to be discharged. At this time, the discharge valve 26 is opened to allow the material in the reactor 5 to flow into the discharge pipe 27 and then be sent to the storage position. During this process, the valve body heater 25 and the pipe heater 28 are turned on to keep the discharge pipe 27 and the discharge valve 26 higher than the ambient temperature, which is conducive to the discharge of the material.

[0106] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
