Technical Field

[0001] The utility model relates to the field of metal smelting furnaces, in particular to a rapid cooling metal smelting furnace. Background Art

[0002] A metal melting furnace is a device used to melt metal, usually made of high-temperature resistant materials. Its main function is to heat solid metal to its melting point, turning it into liquid for further processing and treatment.

[0003] During the operation of a metal smelting furnace, the metal is heated to high temperatures, causing a sharp rise in internal furnace temperatures. If heat is not dissipated promptly, the furnace may overheat and damage, even leading to safety accidents. Furthermore, the furnace is at high risk of damage and cracking due to unexpected circumstances during use. During smelting, the high-temperature melt can come into contact with large amounts of cooling water, causing splashing or explosions, potentially damaging the equipment and the environment. Therefore, overcoming these existing technical problems and drawbacks has become a key issue that needs to be addressed. Utility Model Content

[0005] To achieve the aforementioned objectives, the present invention provides a technical solution: a rapid cooling metal smelting furnace comprising a furnace frame, on which a furnace body is hingedly mounted. A heat dissipation unit is disposed within the furnace body to cool the furnace body. An isolation plate is provided between the heat dissipation unit and the furnace body to prevent contact between the molten metal and the liquid, which could lead to explosion risk. A cooling box is disposed on the side of the furnace frame, connected to the heat dissipation unit, and within the cooling box is a cooling unit for rapidly cooling the heat dissipation medium, thereby achieving rapid heat dissipation from the furnace.

[0006] In the aforementioned rapid cooling metal smelting furnace, the furnace body comprises a furnace body hingedly connected to a furnace frame, enabling the furnace body to swing, facilitating the pouring of molten metal after smelting.

Therefore, they cannot be understood as limitations on the present invention.

[0025] See also Figure 1-Figure 3The rapid cooling metal smelting furnace of this embodiment can rapidly cool down the furnace by spraying liquid into the furnace. It can also rapidly cool down the high-temperature heated liquid by combining multiple methods to form a cooling cycle, continuously and rapidly cooling the furnace to ensure normal operation of the furnace. It can also isolate the interior of the furnace to prevent splashing and explosions caused by unexpected contact between high-temperature solution and liquid, which could damage the equipment and the outside world. In this embodiment, it mainly includes a furnace frame 1, on which a furnace body 2 is hingedly mounted. The furnace body 2 includes a furnace body 21 hingedly mounted to the furnace frame 1, which allows the furnace body 21 to swing and facilitate the pouring of the molten metal after smelting. A removable liner 22 is provided inside the furnace body 21. The liner 22 is made of refractory material and is used to place metal for smelting. A heating element 23 is provided on the furnace body 21 between the liner 22 and the furnace body 21. The heating element 23 is a mature existing technology and will not be described in detail here. The metal solution is heated by the heating element 23 , which can be achieved by arc discharge, induction heating, gas combustion, high-frequency electromagnetic waves, and the like.

[0026] To achieve rapid cooling of the furnace. Figure 2 In this embodiment, a heat dissipation unit 3 is installed within the furnace body 2 to cool the furnace body 2. An isolation plate 4 is installed between the heat dissipation unit 3 and the furnace body 2. The isolation plate 4 is made of refractory material and isolates the furnace interior to prevent splashing and explosions caused by unexpected high-temperature solution contact with liquid, which could damage the equipment and the outside world. The heat dissipation unit 3 includes a heat dissipation box 31, located within the furnace body 21 and designed to conform to the liner 22. The isolation plate 4 is installed on the heat dissipation box 31 between the heat dissipation box 31 and the liner 22, and fits closely with the liner 22, thereby facilitating rapid heat transfer and subsequent heat dissipation. An annular nozzle 32 is fixed to the top of the heat dissipation box 31. The nozzle 32 is equipped with multiple nozzles 33 facing the isolation plate 4. The nozzles 33 spray liquid onto the inner wall of the heat dissipation box 31 in contact with the isolation plate 4, quickly removing heat from the isolation plate 4 and rapidly cooling the liner 22.

[0027] In order to achieve continuous cooling of the furnace. In this embodiment, see Figure 3A cooling box 5 is mounted on the side of the grate 1 and is connected to the heat dissipation unit 3. The cooling chamber 61 is filled with liquid. A cooling unit 6 is installed inside the cooling box 5 to rapidly cool the heat dissipation medium. A water storage tank 7 is mounted on the side of the cooling box 5 and is filled with liquid. The cooling unit 6 includes a cooling chamber 61 defined within the cooling box 5. A spiral water pipe 62 is fixedly installed within the cooling chamber 61. The top of the water pipe 62 extends through the cooling box 5 and connects to the interior of the water storage tank 7. The bottom of the water pipe 62 extends through the bottom end of the cooling box 5 and connects to the bottom end of the heat dissipation box 31. A first liquid pump 63 is fixedly installed at the bottom of the water pipe 62. The first liquid pump 63 pumps the high-temperature liquid in the heat dissipation box 31 into the water pipe 62. The high-temperature liquid in the water pipe 62 then transfers heat to the liquid in the cooling chamber 61, cooling the liquid. During this process, the spiral water pipe 62 extends the heat dissipation time. The cooling box 5 has a ventilation chamber 64 enclosing the cooling chamber 61. The ventilation chamber 64 has a spiral air duct 65. The spiral air duct 65 increases the contact area between the flowing air and the cooling chamber 61, thereby improving the cooling efficiency. The bottom of the cooling box 5 has multiple vents 66 connected to the ventilation chamber 64. The bottom of the cooling box 5 is fixed with a blower 67 connected to the ventilation chamber 64. When the liquid in the water pipe 62 is cooled, the temperature of the liquid in the cooling chamber 61 gradually increases. At this time, the blower 67 ventilates the ventilation chamber 64. At this time, the wind passes through the air duct 65 and carries away the temperature in the cooling chamber 61 through the vents 66, thereby cooling the liquid.

[0028] The cooling box 5 is connected to the top and bottom of the water tank 7 via water exchange pipes 71 at its top and bottom, respectively. A second liquid pump 68 is fixedly mounted on the water exchange pipe 71 at the bottom, capable of circulating the liquid between the cooling box 5 and the water tank 7, thereby rapidly cooling the liquid. A cooler 69 is fixedly mounted at the bottom end of the water tank 7 and inserted into the interior of the water tank 7. This cooler 69 is a mature existing technology and will not be described in detail here. The cooler 69 can be of an immersion liquid type, a semiconductor type, a liquid nitrogen type, or the like. This cools the liquid in the water tank 7 again. The water tank 7 is connected to the nozzle 32 via a water supply pipe 72 connected to its interior. A third liquid pump 70 is fixedly mounted on the water supply pipe 72. The third liquid pump 70 supplies the cooled liquid into the nozzle 32 to re-cool the liner 22, thereby circulating the liquid and achieving continuous cooling of the furnace.

[0029] The method of using the rapid cooling metal melting furnace of the present invention is as follows: first, the metal material is placed in the bushing 22, and the metal is melted by the heating body. During this process, the first liquid pump 63, the second liquid pump 68, the third liquid pump 70, the blower 67 and the refrigerator 69 are controlled to work. At this time, the cooled liquid is supplied to the inside of the nozzle 32 by the third liquid pump 70, and the nozzle 32 sprays the liquid to the inner wall of the heat sink 31 in contact with the isolation plate 4 through the nozzle 33, thereby quickly taking away the heat on the isolation plate 4 and realizing rapid cooling of the bushing 22. The liquid accumulates to the bottom of the heat sink 31. At this time, the high-temperature liquid inside the heat sink 31 is pumped into the water pipe 62 by the first liquid pump 63. The high-temperature liquid in the water pipe 62 transfers heat through the liquid in the cooling chamber 61 to achieve temperature cooling.

[0030] At the same time, the temperature of the liquid in the cooling chamber 61 gradually increases. At this time, the blower 67 ventilates the inside of the ventilation chamber 64. At this time, the wind passes through the air duct 65 and takes away the temperature in the cooling chamber 61 through the vent 66, thereby cooling the liquid. At this time, the refrigerator 69 cools the liquid in the water tank 7 again, thereby cooling the liquid. The second liquid pump 68 circulates the liquid between the cooling chamber 61 and the water tank 7 through the water exchange pipe 71, and supplies the cooled liquid to the inside of the nozzle 32 through the third liquid pump 70 to cool the bushing 22 again, thereby circulating the liquid and achieving continuous cooling of the furnace. In this process, the interior of the furnace is isolated by the isolation plate 4 to avoid splashing and explosion caused by the contact of high-temperature solution with the liquid due to unexpected circumstances, which may cause damage to the equipment and the outside world.
