Description

Technical Field

[0001] The utility model relates to the field of ultrafine crystal production equipment, in particular to a melting device with a protection mechanism for producing ultrafine crystal strips. Background Art

[0002] The traditional method for preparing ultrafine crystal strips is to melt the metal into liquid through a smelting device, pour the molten metal into a tundish, bottom-fill it into a spray bag, and spray the molten metal through a nozzle onto a high-speed rotating crystallization roller, where it instantly solidifies into an ultrafine crystal strip with a thickness of 25 to 30 microns.

[0003] However, in the use of the smelting device in the prior art, the cover of the furnace chamber needs to be manually taken and placed, and the molten metal is discharged from the bottom after smelting. Although a cooling device is used to reduce the temperature of the smelting device, it takes a certain amount of time to cool down. If the cover is opened during this period, it is easy to cause high temperature burns to the workers, and it is difficult to ensure the safety of the smelting device when in use;

[0004] After one processing is completed, the cover needs to be opened to feed materials into the furnace chamber for further processing. When the cover is opened, steam sprays out from the furnace chamber to the surroundings, which can easily cause burns to the operator, and it is difficult to protect the operator when opening the cover.

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0006] The utility model aims to provide a melting device for producing ultrafine crystal ribbons with a protective mechanism, so as to solve the problems that opening the cover during processing in the existing melting device can easily scald the staff, making it difficult to ensure the safety during use and difficult to protect the operator when opening the cover.

[0007] The purpose of the utility model can be achieved through the following technical scheme: a melting device for producing ultrafine crystal strips with a protective mechanism, comprising a fixed frame, a furnace body is fixedly installed on the fixed frame, a protrusion is fixedly installed on the top of the furnace body, a locking mechanism is fixedly installed inside the protrusion, a cover body is fixedly connected to the top of the furnace body through the locking mechanism, a rotating rod is movably installed on the fixed frame, and a rotating wheel is fixedly installed on the end of the rotating rod away from the fixed frame.

[0008] Preferably, the locking mechanism includes a plurality of bases and movable rods, the bases are fixedly mounted in the inner wall of the furnace body, the movable rods are movably mounted in the bases, the interior of the bases is filled with carbon dioxide gas, and locking blocks are movably mounted inside the protrusions.

[0009] Preferably, a locking hole is provided on the outer wall of the protrusion, the locking hole is located at the end of the locking block away from the base, a slope is provided on the bottom of the locking block, the slope fits with the top of the moving rod, and a plurality of locking grooves are provided on the inner wall of the cover, the positions of the locking grooves are adapted to the locking block.

[0010] Preferably, a driving gear is fixedly mounted on one end of the rotating rod away from the rotating wheel, the driving gear is located inside the fixing frame, a rack is movably mounted inside the fixing frame, the rack is located on one side of the driving gear and meshes with the driving gear.

[0011] Preferably, a lifting rod is fixedly connected to the top of the rack, a baffle is movably installed on the top of the fixed frame, and the bottom of the baffle is fixedly connected to an end of the lifting rod away from the rack.

[0012] Preferably, a cavity is opened inside the furnace body, a heating coil is fixedly installed inside the furnace body, the heating coil is spirally wound on the cavity, and a discharge pipe is fixedly connected to the bottom of the cavity.

[0013] The beneficial effects of the utility model are as follows:

[0014] (1) The utility model uses a locking mechanism to first put the raw materials into the furnace body, and then place the cover body on the top of the furnace body. As the heating coil is energized, the temperature inside the furnace body gradually increases. As the temperature of the furnace body increases, the temperature of the carbon dioxide inside the base also gradually increases. As the temperature increases, the volume of carbon dioxide gradually expands, thereby pushing the moving rod to move toward the locking block. When the moving rod moves, its top will abut against the bottom inclined surface of the locking block. Under the action of the moving rod, the locking block gradually rotates until one end of the locking block passes through the locking hole and enters the locking groove, thereby fixing the cover body. After the processing is completed, the molten metal is discharged from the discharge pipe at the bottom of the cavity. At this time, due to the high temperature inside the cavity, the locking block is always locked with the locking groove until the temperature inside the cavity drops to the threshold, the volume of carbon dioxide inside the base is restored, the moving rod is reset, and the locking block and the locking groove are unlocked. At this time, opening the cover body will not cause burns to the workers, thereby ensuring the safety of the smelting device when in use;

[0015] (2) The utility model uses a rotating rod and a baffle in coordination. In the initial state, the bottom of the baffle fits against the top of the fixing frame. When the cover needs to be opened, the rotating wheels on both sides are rotated, and the driving gear and the rack are used to drive the lifting rod to move upward, thereby driving the baffle to move upward until the baffle moves to both sides of the cover. At this time, the cover is opened. When steam sprays to the surroundings, the baffle blocks the steam, thereby protecting the operator when the cover is opened.

[0016] In summary, the utility model not only ensures the safety of the smelting device during use, but also protects the operator when the cover is opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] This embodiment is used to solve the problem that during the use of the smelting device in the prior art, the cover of the furnace chamber needs to be manually taken and placed, and the molten metal is discharged from the bottom after smelting. Although a cooling device is used to reduce the temperature of the smelting device, it takes a certain amount of time to cool down. If the cover is opened during this period, it is easy to cause high temperature burns to the workers, and it is difficult to ensure the safety of the smelting device during use.

[0029] First, the raw materials are put into the furnace body 2, and then the cover body 4 is placed on the top of the furnace body 2. As the heating coil 203 is energized, the temperature inside the furnace body 2 gradually increases. As the temperature of the furnace body 2 increases, the temperature of the carbon dioxide inside the base 301 also gradually increases. As the temperature increases, the volume of the carbon dioxide gradually expands, thereby pushing the moving rod 302 to move toward the locking block 303. When the moving rod 302 moves, its top will abut against the bottom inclined surface 305 of the locking block 303. The locking block 303 gradually rotates under the action of the moving rod 302 until One end of the locking block 303 passes through the locking hole 304 and enters the locking groove 306 to fix the cover body 4. After the processing is completed, the molten metal is discharged from the discharge pipe 204 at the bottom of the cavity 202. At this time, due to the high temperature inside the cavity 202, the locking block 303 is always locked with the locking groove 306 until the temperature inside the cavity 202 drops to the threshold value, the volume of carbon dioxide inside the base 301 is restored, the moving rod 302 is reset, and the locking block 303 and the locking groove 306 are unlocked. At this time, opening the cover body 4 will not cause burns to the workers.

[0031] Embodiment 2:

[0032] This embodiment is used to solve the problem that after one processing is completed, it is necessary to open the cover to feed materials into the furnace chamber for re-processing. When the cover is opened, steam sprays out from the inside of the furnace chamber to the surroundings, which can easily cause burns to the operator and it is difficult to protect the operator when opening the cover.

[0033] See also Figure 6As shown, the utility model also includes a rotating rod 5, which is movably mounted on the fixed frame 1, and a rotating wheel 501 is fixedly mounted on the end of the rotating rod 5 away from the fixed frame 1, and a driving gear 502 is fixedly mounted on the end of the rotating rod 5 away from the rotating wheel 501, and the driving gear 502 is located inside the fixed frame 1, and a rack 503 is movably mounted inside the fixed frame 1, and the rack 503 is located on one side of the driving gear 502 and meshes with the driving gear 502, and a lifting rod 504 is fixedly connected to the top of the rack 503, and a baffle 505 is movably mounted on the top of the fixed frame 1, and the bottom of the baffle 505 is fixedly connected to the end of the lifting rod 504 away from the rack 503.

[0034] In the initial state, the bottom of the baffle 505 is in contact with the top of the fixing frame 1. When the cover body 4 needs to be opened, the rotating wheels 501 on both sides are rotated, and the driving gear 502 and the rack 503 are used to drive the lifting rod 504 to move upward, thereby driving the baffle 505 to move upward until the baffle 505 moves to both sides of the cover body 4. At this time, the cover body 4 is opened, and when the steam is sprayed to the surroundings, the baffle 505 blocks the steam.

[0035] By using the rotating rod 5 and the baffle 505 in coordination, the operator can be protected when the cover body 4 is opened.

[0036] In combination with Example 1 and Example 2, through the locking mechanism 3, when the temperature inside the furnace body 2 is high, carbon dioxide is used to push the moving rod 302 to resist the locking block 303, so that the locking block 303 is engaged and locked with the locking groove 306, until the temperature inside the furnace body 2 drops to a safe range, and the moving rod 302 is reset. At this time, opening the cover body 4 will not cause burns to the workers, effectively ensuring the safety of the smelting device when in use. At the same time, when the cover body 4 is opened, the wheel 501 is rotated, and the driving gear 502 is used to drive the baffle 505 to move upward, so as to block the steam and protect the operator when the cover body 4 is opened.

[0038] First, the raw materials are put into the furnace body 2, and then the cover body 4 is placed on the top of the furnace body 2. As the heating coil 203 is energized, the temperature inside the furnace body 2 gradually increases. As the temperature of the furnace body 2 increases, the temperature of the carbon dioxide inside the base 301 also gradually increases. As the temperature increases, the volume of the carbon dioxide gradually expands, thereby pushing the moving rod 302 to move toward the locking block 303. When the moving rod 302 moves, its top will abut against the bottom inclined surface 305 of the locking block 303. The locking block 303 gradually rotates under the action of the moving rod 302 until one end of the locking block 303 The locking block 303 passes through the locking hole 304 and enters the locking groove 306 to fix the cover 4. After the processing is completed, the molten metal is discharged from the discharge pipe 204 at the bottom of the cavity 202. At this time, due to the high temperature inside the cavity 202, the locking block 303 is always locked with the locking groove 306 until the temperature inside the cavity 202 drops to the threshold, the volume of carbon dioxide inside the base 301 is restored, the moving rod 302 is reset, and the locking block 303 and the locking groove 306 are unlocked. At this time, opening the cover 4 will not cause burns to the workers, ensuring the safety of the smelting device when in use;

[0039] When the cover 4 needs to be opened, the rotating wheels 501 on both sides are rotated, and the driving gear 502 and the rack 503 are used to drive the lifting rod 504 to move upward, thereby driving the baffle 505 to move upward until the baffle 505 moves to both sides of the cover 4. At this time, the cover 4 is opened, and when steam is sprayed to the surroundings, the baffle 505 blocks the steam, thereby protecting the operator when the cover 4 is opened;

[0040] The utility model ensures the safety of the smelting device when in use by cooperating with the locking mechanism 3, the rotating rod 5 and the baffle 505, and also protects the operator when the cover body 4 is opened.
