Description

Technical Field

[0001] This invention relates to the field of metal smelting technology, specifically an energy-saving smelting furnace and its usage method. Background Technology

[0002] A reduction distillation furnace, also known as a primary distillation furnace, usually refers to a reduction distillation furnace for sponge titanium. This type of equipment is mainly used for the reduction distillation treatment of sponge titanium. When using a primary distillation furnace, cooling treatment is required, mainly to ensure the safe operation of the equipment and improve the quality of the product.

[0003] The prior art discloses a Chinese patent with application number CN202411077428.6, which discloses a calcining furnace for metal manufacturing. The patent discloses a hydraulic cylinder driving traction component to control the tilting of the calcining furnace body. The calcining furnace body is driven to rotate by a drive motor, thereby causing the furnace body inside to rotate, so that the reaction liquid inside is tilted, thus avoiding premature sintering of the reaction liquid due to uneven heating.

[0004] Although the above-mentioned device can prevent sintering during metal smelting, it still has some drawbacks in use: When the steam oven is in use, the direct discharge of a large amount of heat energy will result in the waste of heat energy. Furthermore, when cooling the steam oven, since the hot air inside contains a large number of harmful substances, direct cooling through discharge can achieve cooling, but on the one hand, it will cause environmental pollution, and on the other hand, it will lead to a large loss of heat, thereby increasing the overall energy consumption of the device, which is not conducive to energy conservation and environmental protection. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving steam oven and its usage method, so as to solve the technical problem mentioned in the background art of recovering and utilizing heat during the cooling of the interior of the steam oven to improve energy efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions: An energy-saving smelting furnace includes a furnace body with a detachable sealing plate on the top and a cooling chamber.

[0010] Preferably, an air cylinder communicating with the interior of the air inlet pipe is provided on one side, a piston rod is slidably installed in the middle of the air cylinder, a motor is fixedly installed on one side of the furnace body, a cam is fixedly installed on the output end of the motor, a round shaft on one side of the cam slides at the bottom of the piston rod, an air collection box fixed to the furnace body is connected to one side of the air outlet pipe, a one-way valve is provided in both the air inlet pipe and the air outlet pipe, a preheating pipe is fixedly installed on the air collection box, and one end of the preheating pipe is fixedly connected to a threaded air pipe.

[0011] Preferably, a water outlet tank is fixedly installed on the furnace body, and a water outlet pipe is provided on the water outlet tank. An external component connected to the water outlet tank is fixedly installed on the outside of the water outlet pipe. A through rectangular groove is opened between the external component and the water outlet pipe. A baffle plate for controlling the water flow in the water outlet pipe is slidably installed in the rectangular groove. A connecting pipe communicating with the inside of the gas cylinder is provided at the upper end. A rectangular box is fixedly installed at one end of the connecting pipe. A movable plate is slidably installed on the rectangular box. The movable plate is connected to a rubber plug. A spring connected to the rectangular box is provided above the movable plate. A rubber plug located inside the connecting pipe is also provided on the movable plate.

[0012] Preferably, a water guide pipe is fixedly installed on one side of the water outlet pipe, and a water collection tank fixed to the furnace body is fixedly installed on the side of the water guide pipe away from the water outlet pipe. A circulation pipe is provided on the water collection tank, and one end of the circulation pipe is connected to a threaded water pipe.

[0013] Preferably, the emission unit includes multiple circumferentially arranged exhaust pipes, with a common circumferential pipe installed between the multiple exhaust pipes. A filter box is fixedly installed at one end of the circumferential pipe, and activated carbon is provided inside the filter box.

[0014] The furnace body is equipped with a bottom component, and a base is fixedly installed on the lower part of the bottom component. Multiple hydraulic rods are fixedly installed on the base, and the end of the hydraulic rod away from the base is fixedly connected to the furnace body.

[0015] Another object of the present invention is to provide a method of using an energy-saving steam oven, comprising the following steps: S1: Metal raw material processing: The holding unit places the metal material during processing, and the rotation of the holding unit can evenly disperse the metal material during smelting to avoid sintering. S2: Internal cooling of the furnace body: By injecting gas and liquid into the threaded gas pipe and threaded water pipe respectively, heat exchange can be achieved between the threaded gas pipe and the threaded water pipe, thereby cooling the furnace.

[0016] The beneficial effects of this invention are: 1. This invention, through the arrangement of threaded gas pipes and threaded water pipes, can, on the one hand, cool the interior of the furnace and recover the hot gas and hot water discharged from the heat exchange, allowing for secondary utilization of its thermal energy. On the other hand, the threaded gas pipes and threaded water pipes can also preheat the interior of the furnace before operation, thereby accelerating the rise in furnace temperature and reducing the overall energy consumption of the device. Through the arrangement of the holding unit, on the one hand, the metal raw materials can be placed during smelting, and on the other hand, the raw materials can be evenly turned over to ensure more complete reaction between the raw materials, improve reaction efficiency, and avoid clumping.

[0017] 2. This invention, through the arrangement of the holding unit, can place the metal raw materials during smelting and also evenly turn them over to ensure a more complete reaction, improve reaction efficiency, and prevent clumping. The cleaning component allows for simultaneous cleaning of the furnace interior by rotating the raw materials, removing dirt from the furnace walls and preventing acidic substances from adhering to the furnace for extended periods and causing corrosion. Compared to existing smelting furnaces, this invention can achieve cooling by exchanging heat with the furnace through threaded gas and water pipes during metal smelting, and also allows for the recovery and reuse of heat energy within the furnace, thereby reducing the overall energy consumption of the device.

[0018] 3. In this invention, when the holding rack moves up and down, the arc-shaped plate and the impact rod also move up and down accordingly. When the impact rod moves up and down, it can impact one side of the flipping plate. At this time, the flipping plate rotates along the axis of the shaft. When the flipping plate rotates, it synchronously drives the shaft and multiple flipping plates to rotate, thereby turning over the raw materials in the holding rack. Compared with the existing steam oven, this invention can turn over the metal raw materials during metal processing, so that they are heated evenly on the one hand and sintering is avoided on the other hand.

[0019] 4. This invention uses a motor to drive a cam to rotate. When the cam rotates, the circular shaft drives the piston rod to compress the gas inside the cylinder. When the gas inside the cylinder is compressed by the piston rod, the gas inside is transferred to the threaded gas pipe through the inlet pipe, thus completing the gas injection. Gas injection achieves air cooling. The high-temperature hot gas in the threaded gas pipe, after being impacted by the gas, is discharged through the outlet pipe to the gas collection box for storage. The gas collection box stores the recovered hot gas. The preheating pipe can also discharge the recovered hot gas into the threaded gas pipe to preheat the furnace body before use. The one-way valve prevents the hot gas in the threaded gas pipe from flowing towards the inlet pipe when the piston rod is drawing gas from inside the cylinder. Compared with existing devices, this invention can exchange heat with the high temperature inside the furnace body, thereby achieving a cooling effect without the need to discharge the high temperature inside the furnace body.

[0020] 5. When the gas cylinder of this invention is compressed by the piston rod, the gas inside can also impact the connecting pipe. After being impacted by the gas pressure, the rubber plug and the moving plate push the spring to move upward. At this time, the rubber plug moves out of the connecting pipe. When the moving plate moves upward, it simultaneously drives the barrier plate to move upward. When the barrier plate moves upward, it removes the blockage on the drain pipe. At this time, the liquid in the outlet tank is discharged to the inlet pipe through the drain pipe, and finally the liquid is transported to the threaded water pipe through the inlet pipe. By injecting liquid into the threaded water pipe, water cooling is achieved. The original high-temperature liquid in the threaded water pipe is discharged to the guide pipe through the outlet pipe and finally stored in the collection tank. The collection tank is equipped with a circulation pipe, which can transfer the high-temperature liquid back to the threaded water pipe for preheating of the furnace body when the device is used again. At this time, in conjunction with the gas collection box and the preheating pipe, the recovered hot gas is discharged into the threaded gas pipe, which can accelerate the preheating of the furnace body, thereby efficiently achieving energy saving when the device is in use.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As attached Figures 1-8 As shown, an energy-saving smelting furnace includes a furnace body 1. A sealing plate is detachably installed on the top of the furnace body 1, and a cooling chamber 10 is provided on the top. A threaded air pipe 31 is provided inside the cooling chamber 10, and a threaded water pipe 48 is provided outside the threaded air pipe 31. An air inlet pipe 30 and an air outlet pipe 36 are respectively installed at the upper and lower air inlet ends and the lower air outlet ends of the threaded air pipe 31. A water inlet pipe 40 connected to the threaded water pipe 48 is provided outside the air inlet pipe 30, and a water outlet pipe 47 connected to the threaded water pipe 48 is provided outside the air outlet pipe 36. A holding unit for placing smelting raw materials is provided on the upper part of the furnace body 1, and a cleaning component for cleaning the inner cavity of the furnace body 1 is provided below the holding unit.

[0025] The threaded gas pipe 31 and threaded water pipe 48 serve two purposes: firstly, they allow for cooling of the furnace body 1 and separate recovery of the hot gas and hot water discharged from the heat exchange, enabling secondary utilization of thermal energy; secondly, they preheat the furnace body 1 before operation, accelerating the temperature rise and reducing overall energy consumption. The holding unit allows for the placement of metal raw materials during smelting and ensures even agitation, guaranteeing a more complete reaction, improving efficiency, and preventing clumping. The cleaning components further enhance the cleaning process. The rotation of the raw materials simultaneously cleans the furnace interior, removing dirt from the furnace walls and preventing acidic substances from adhering to the furnace for extended periods and causing corrosion. Compared to existing steam furnaces, this invention enables heat exchange within the furnace during metal smelting via threaded gas pipes 31 and threaded water pipes 48, achieving cooling and recovering heat energy, thereby reducing overall energy consumption. The combination of a holding unit and a cleaning unit allows the rotation of the holding unit to scrape and clean the inner wall of the furnace body 1 while the raw materials are being evenly turned, thus removing internal dirt and improving heating efficiency.

[0026] As attached Figure 6 , Figure 7 As shown, the holding unit includes two symmetrically arranged support plates 20 that are rotatably connected to the inner wall of the furnace body 1 via electric sliders. A moving groove is provided on one side of the support plate 20, and an installation component 21 is slidably installed in the moving groove. A spring is provided below the installation component 21. A placement plate 22 is snapped onto the upper end of the installation component 21. A baffle 211 that is slidably connected to the installation component 21 is provided above the placement plate 22. A holding rack 23 is installed between the two placement plates 22. A connecting rod 224 is fixedly installed at the lower end of the placement plate 22. A bracket 225 for supporting the bottom of the holding rack 23 is installed between the two connecting rods 224.

[0027] By installing the placement plate 22 on the mounting component 21, and then moving the baffle 211 to block the top of the placement plate 22, the raw material is inverted into the holding rack 23. When the cylinder 223 extends and retracts, the holding rack 23 can be raised and lowered, so that the raw material inside is shaken and vibrated, so that the raw material inside can be heated evenly when it is processed in the furnace body 1.

[0028] The holding rack 23 has shafts 24 rotatably mounted on both sides. Multiple equally spaced flip plates 241 are installed between the two shafts 24. A brush plate is detachably installed on the inner wall of the flip plate 241. A flip plate 242 is fixedly installed at the end of the shaft 24. An arc plate 221 is fixedly installed on the placement plate 22 on one side. An impact rod 222 is fixedly installed below the arc plate 221. The placement plate 22 is provided with ear plates. A cylinder 223 is fixedly connected to the sealing plate above the ear plates.

[0029] When the holding rack 23 moves up and down, the arc plate 221 and the impact rod 222 also move up and down accordingly. When the impact rod 222 moves up and down, it can impact one side of the flip plate 242. At this time, the flip plate 242 rotates along the axis of the shaft 24. When the flip plate 242 rotates, it synchronously drives the shaft 24 and multiple flip plates 241 to rotate, thereby turning over the raw materials in the holding rack 23. Compared with the existing steam oven, the present invention can turn over the metal raw materials when processing metal, so as to make them heat evenly on the one hand and avoid sintering on the other hand.

[0030] As attached Figure 6 As shown, the cleaning assembly includes a hanging plate 25. A hollow frame 251 located in the middle of the furnace body 1 is fixedly installed on one side of the hanging plate 25. Multiple circumferentially arranged sleeve plates 252 are fixedly installed on the outer side of the hollow frame 251. An installation plate 253 is fixedly installed in the middle of the sleeve plate 252. A scraper 254 is fixedly installed on one side of the installation plate 253.

[0031] When the holding unit rotates inside the furnace body 1, the arrangement of the hanging plate 25, hollow frame 251 and sleeve plate 252 can drive multiple scrapers 254 to rotate synchronously, thereby scraping off and cleaning the dirt on the inner wall of the furnace body 1. By cleaning the inner wall of the furnace body 1, the efficiency of heat conduction inside the furnace can be improved on the one hand, and corrosion caused by scale buildup on the inner wall can be avoided on the other hand, thereby reducing the overall cleaning and maintenance costs of the device.

[0032] As attached Figure 2 As shown, an air cylinder 320 communicating with the interior of the air inlet pipe 30 is provided on one side. A piston rod 32 is slidably installed in the middle of the air cylinder 320. A motor 33 is fixedly installed on one side of the furnace body 1. A cam 34 is fixedly installed at the output end of the motor 33. A round shaft on one side of the cam 34 slides at the bottom of the piston rod 32. An air collection box 35 fixed to the furnace body 1 is connected to one side of the air outlet pipe 36. A one-way valve is provided in both the air inlet pipe 30 and the air outlet pipe 36. A preheating pipe 351 is fixedly installed on the air collection box 35. One end of the preheating pipe 351 is fixedly connected to the threaded air pipe 31.

[0033] When cooling is required inside the furnace body 1, the motor 33 is activated to rotate the cam 34. As the cam 34 rotates, the shaft drives the piston rod 32 to compress the gas inside the gas cylinder 320. When the gas inside the gas cylinder 320 is compressed by the piston rod 32, the gas inside is transferred through the inlet pipe 30 to the threaded gas pipe 31, thus completing the gas injection. Gas cooling is achieved through this gas injection. The high-temperature hot gas inside the threaded gas pipe 31, after being impacted by the gas, is discharged through the outlet pipe 36 to the gas collection box 35 for storage. The gas box 35 stores the recovered hot gas. The preheating pipe 351 can also discharge the recovered hot gas into the threaded gas pipe 31 to preheat the inside of the furnace body 1 before use. The one-way valve prevents the hot gas in the threaded gas pipe 31 from flowing towards the air inlet pipe 30 when the piston rod 32 is sucking inside the gas cylinder 320. Compared with the existing device, the present invention can exchange heat with the high temperature inside the furnace body 1, thereby achieving the effect of cooling without discharging the high temperature inside the furnace body 1.

[0034] As attached Figure 1 , Figure 8 As shown, a water outlet tank 41 is fixedly installed on the furnace body 1. A water outlet pipe 42 is provided on the water outlet tank 41. An external component 43 connected to the water outlet tank 41 is fixedly provided on the outside of the water outlet pipe 42. A through rectangular groove is opened between the external component 43 and the water outlet pipe 42. A baffle plate 462 for controlling the water flow of the water outlet pipe 42 is slidably installed in the rectangular groove. A connecting pipe 45 communicating with the inside of the air cylinder 320 is provided at the upper end. A rectangular box 44 is fixedly installed at one end of the connecting pipe 45. A movable plate 46 is slidably installed on the rectangular box 44. The movable plate 46 is connected to a rubber plug 461. A spring connected to the rectangular box 44 is provided above the movable plate 46. A rubber plug 461 located inside the connecting pipe 45 is also provided on the movable plate 46.

[0035] When the gas inside the cylinder 320 is compressed by the piston rod 32, the gas inside can also impact the connecting pipe 45. After being impacted by the gas pressure, the rubber stopper 461 and the moving plate 46 push the spring to move upward. At this time, the rubber stopper 461 moves out of the connecting pipe 45. When the moving plate 46 moves upward, it simultaneously drives the baffle plate 462 to move upward. When the baffle plate 462 moves upward, it releases the blockage on the drain pipe 42. At this time, the liquid in the outlet tank 41 is discharged through the drain pipe 42 to the inlet pipe 40, and finally the liquid is transported to the threaded water pipe 48 through the inlet pipe 40. Liquid is injected into the interior to achieve water cooling. The original high-temperature liquid in the threaded water pipe 48 is discharged to the water guide pipe 471 through the water outlet pipe 47 and finally stored in the water collection tank 472. The high-temperature liquid can be transferred back to the threaded water pipe 48 through the circulation pipe on the water collection tank 472 so that it can be used to preheat the furnace body 1 when the device is used again. At this time, in conjunction with the gas collection box 35 and the preheating pipe 351, the recovered hot gas is discharged into the threaded gas pipe 31, which can accelerate the preheating of the furnace body 1, thereby achieving energy saving when the device is used.

[0036] A water guide pipe 471 is fixedly installed on one side of the water outlet pipe 47. A water collection tank 472 fixed to the furnace body 1 is fixedly installed on the side of the water guide pipe 471 away from the water outlet pipe 47. A circulation pipe is provided on the water collection tank 472, and one end of the circulation pipe is connected to the threaded water pipe 48.

[0037] As attached Figure 3 As shown, the emission unit includes multiple circumferentially arranged exhaust pipes 51, and a circumferential pipe 52 is installed between the multiple exhaust pipes 51. A filter box 53 is fixedly installed at one end of the circumferential pipe 52, and activated carbon is provided inside the filter box 53.

[0038] When the gas inside the furnace body 1 is discharged, the gas inside the furnace body 1 can be discharged through the circumferential pipe 52 to the filter box 53 by opening the exhaust pipe 51. The activated carbon filters and adsorbs the harmful substances inside the gas. Finally, the gas is discharged outward through one side of the filter box 53. By controlling the number of times the exhaust pipe 51 is opened, the gas discharge rate inside the furnace body 1 can be controlled.

[0039] A bottom component 11 is provided below the furnace body 1. A base 12 is fixedly installed on the lower part of the bottom component 11. Multiple hydraulic rods 13 are fixedly installed on the base 12. The end of the hydraulic rod 13 away from the base 12 is fixedly connected to the furnace body 1.

[0040] Another object of the present invention is to provide a method of using an energy-saving steam oven, comprising the following steps: S1: Metal raw material processing: The holding unit places the metal material during processing, and the rotation of the holding unit can evenly disperse the metal material during smelting to avoid sintering. S2: Internal cooling of the furnace body: By injecting gas and liquid into the threaded gas pipe 31 and the threaded water pipe 48 respectively, heat exchange can be achieved between the threaded gas pipe 31 and the threaded water pipe 48, thereby achieving furnace cooling.

[0041] In use, the placement plate 22 is installed on the mounting component 21. Then, the baffle 211 is moved to block the top of the placement plate 22, inverting the raw material into the holding rack 23. The holding rack 23 is raised and lowered by the extension and retraction of the cylinder 223, causing the raw material inside to vibrate and shake, ensuring even heating during processing in the furnace 1. As the holding rack 23 moves up and down, the arc-shaped plate 221 and the impact rod 222 also move up and down. When the impact rod 222 moves up and down, it impacts one side of the flip plate 242, causing the flip plate 242 to rotate along the axis of the shaft 24. The rotation of the flip plate 242 synchronously drives the shaft. The 24 and multiple flipping plates 241 rotate to flip the raw materials in the holding rack 23. Compared with the existing steam oven, the present invention can flip the metal raw materials during metal processing, so as to make them heat evenly and avoid sintering. When the holding unit rotates in the furnace body 1, the setting of the hanging plate 25, hollow frame 251 and sleeve plate 252 can drive multiple scrapers 254 to rotate synchronously, thereby scraping off and cleaning the dirt on the inner wall of the furnace body 1. By cleaning the inner wall of the furnace body 1, the efficiency of heat conduction in the furnace can be improved, and corrosion caused by scale buildup on the inner wall can be avoided, thereby reducing the overall cleaning and maintenance costs of the device. When cooling is required inside the furnace body 1, the motor 33 is activated to rotate the cam 34. As the cam 34 rotates, the shaft drives the piston rod 32 to compress the gas inside the gas cylinder 320. When the gas inside the gas cylinder 320 is compressed by the piston rod 32, the gas inside is transferred through the inlet pipe 30 to the threaded gas pipe 31, thus completing the gas injection. Gas cooling is achieved through this gas injection. The high-temperature hot gas inside the threaded gas pipe 31, after being impacted by the gas, is discharged through the outlet pipe 36 to the gas collection box 35 for storage. The gas box 35 stores the recovered hot gas. The preheating pipe 351 can also discharge the recovered hot gas into the threaded gas pipe 31 to preheat the inside of the furnace body 1 before use. The one-way valve prevents the hot gas in the threaded gas pipe 31 from flowing towards the air inlet pipe 30 when the piston rod 32 is sucking inside the gas cylinder 320. Compared with the existing device, the present invention can exchange heat with the high temperature inside the furnace body 1, thereby achieving the effect of cooling without discharging the high temperature inside the furnace body 1. When the gas inside the cylinder 320 is compressed by the piston rod 32, the gas inside can also impact the connecting pipe 45. After being impacted by the gas pressure, the rubber stopper 461 and the moving plate 46 push the spring to move upward. At this time, the rubber stopper 461 moves out of the connecting pipe 45. When the moving plate 46 moves upward, it simultaneously drives the baffle plate 462 to move upward. When the baffle plate 462 moves upward, it removes the blockage on the drain pipe 42. At this time, the liquid in the outlet tank 41 is discharged to the inlet pipe 40 through the drain pipe 42. Finally, the liquid is transported to the threaded water pipe 48 through the inlet pipe 40. By injecting liquid into the threaded water pipe 48, water cooling is achieved. The original high-temperature liquid in the threaded water pipe 48 is discharged to the guide pipe 471 through the outlet pipe 47 and finally located in the... The water is stored in the water collection tank 472, and the high-temperature liquid can be transferred back to the threaded water pipe 48 through the circulation pipe on the water collection tank 472 so that the furnace body 1 can be preheated when the device is used again. At this time, in conjunction with the gas collection box 35 and the preheating pipe 351, the recovered hot gas is discharged into the threaded gas pipe 31, which can accelerate the preheating of the furnace body 1, thereby achieving energy saving when the device is used. By opening the exhaust pipe 51, the gas inside the furnace body 1 can be discharged to the filter box 53 through the annular pipe 52 to filter and adsorb harmful substances in the gas. Finally, the gas is discharged out through one side of the filter box 53. By controlling the number of times the exhaust pipe 51 is opened, the gas discharge rate inside the furnace body 1 can be controlled.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
