Description

Technical Field

[0001] This utility model relates to the field of crucible furnace technology, and in particular to a crucible furnace safety protection device. Background Technology

[0002] Crucible furnaces, as a commonly used heat treatment device, are widely used in industrial settings such as metal smelting, casting, and material heating. Their working principle involves heating the material placed inside the crucible through fuel combustion or electric heating elements to meet the requirements of the production process.

[0003] In actual use, the surface of the crucible furnace and the area surrounding the crucible reach extremely high temperatures, sometimes hundreds or even thousands of degrees Celsius. Operators are highly susceptible to severe burns if they accidentally come into contact with these high-temperature components while adding materials, moving the crucible, or inspecting equipment. Furthermore, when the material inside the crucible is heated to a molten state, uneven heating, crucible aging or damage, or improper operation can cause molten material to splash out, damaging surrounding equipment and posing a serious threat to the safety of operators.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. By fixing a first protective sleeve to the bottom of both the first and second connecting rings, the cooperation of the two sets of first protective sleeves can prevent operators from directly contacting the outer wall of the crucible furnace body, thereby preventing burns to the workers. Since protective components are provided at the top of both the first and second connecting rings, the two sets of protective components (receiving ring and second protective sleeve) can increase the overall height of the crucible furnace body, thereby preventing molten material from splashing out of the crucible furnace body and ensuring the safety of surrounding equipment and personnel. Utility Model Content

[0012] Preferably, the top of the movable plate is fixed with a connecting ear, the outer wall of the connecting ear is provided with a threaded hole, a threaded clamp rod is threadedly connected in the threaded hole, and a rotating wheel is fixed at one end of the threaded clamp rod; Limiting holes are provided on the outer wall of the crucible furnace body.

[0013] The beneficial effects of this utility model are: 1. First, engage the first and second locking blocks into the first and second locking slots respectively. This will connect the first and second connecting rings to the outer wall of the crucible furnace body. Then, rotate the rotary wheel. The rotary wheel will drive the threaded locking rod to move within the threaded hole. When one end of the threaded locking rod disengages from the limiting hole, the spring will drive the telescopic rod to extend. The telescopic rod will then drive the movable plate to move within the movable slot. The movable plate will drive the connecting plate, the first locking pin, and the second locking pin to move. When the first and second locking pins are engaged in the corresponding locking holes, that is... The first and second connecting rings can be fixed in place. By fixing a first protective sleeve to the bottom of both the first and second connecting rings, the operation can be prevented from directly contacting the outer wall of the crucible furnace body, thus avoiding burns to the workers. Since protective components are provided at the top of both the first and second connecting rings, the two sets of protective components (receiving ring and second protective sleeve) can increase the overall height of the crucible furnace body, thereby preventing molten material from splashing out of the crucible furnace body and ensuring the safety of surrounding equipment and workers.

The telescopic rod will then drive the movable plate to move in the movable slot. The movable plate will drive the connecting plate, the first locking pin, and the second locking pin to move. When the first and second locking pins are engaged in the corresponding locking holes, the first and second connecting rings can be fixed. When disassembling the two sets of first protective sleeves and two sets of protective components (receiving ring and second protective sleeve), first move the movable plate in the movable slot. At this time, the spring and the telescopic rod will retract. When the movable plate moves, it drives the connecting plate to move. After the first and second locking pins disengage from the first and second locking holes respectively, the rotating wheel drives the threaded locking rod to move within the threaded hole. When one end of the threaded locking rod engages with the limiting hole, the installation components (telescopic rod, spring, movable plate, connecting plate, first locking pin, second locking pin) can be fixed, preventing the installation components from affecting the disassembly of the two sets of first protective sleeves and two sets of protective components (receiving ring, second protective sleeve). Then, the first and second connecting rings are driven to separate. After the first locking block disengages from the first locking groove and the second locking block disengages from the second locking groove, the two sets of first protective sleeves and two sets of protective components (receiving ring, second protective sleeve) can be disassembled. In summary, this utility model facilitates the installation and disassembly of the two sets of first protective sleeves and two sets of protective components (receiving ring, second protective sleeve), making it convenient to use.

Please see Figures 1-4 As shown, this embodiment is a crucible furnace safety protection device, including: a protection component 200, including a first connecting ring 201 and a second connecting ring 202 correspondingly disposed on the outer wall of the crucible furnace body 100, two sets of first protective sleeves 203 correspondingly fixed to the bottom of the first connecting ring 201 and the second connecting ring 202, and two sets of protective members correspondingly disposed on the top of the first connecting ring 201 and the second connecting ring 202; the two sets of protective members include two sets of connecting blocks 204 correspondingly fixed to the top of the first connecting ring 201 and the second connecting ring 202, two sets of receiving rings 205 correspondingly fixed to the top of the two sets of connecting blocks 204, and two sets of second protective sleeves 206 correspondingly fixed to the outer wall of the two sets of receiving rings 205, wherein the two sets of first protective sleeves 203 and the two sets of second protective sleeves 206 are all made of thermally insulating material; First, engage the first locking block 208 and the second locking block 210 into the first locking groove 207 and the second locking groove 209 respectively. This will connect the first connecting ring 201 and the second connecting ring 202 to the outer wall of the crucible furnace body 100. Then, rotate the rotating wheel 313. The rotating wheel 313 will drive the threaded locking rod 312 to move in the threaded hole 311. When one end of the threaded locking rod 312 disengages from the limiting hole 314, the spring 306 will drive the telescopic rod 305 to stretch. The telescopic rod 305 will then drive the movable plate 304 to move in the movable groove 303. The movable plate 304 will drive the connecting plate 307, the first locking pin 308, and the second locking pin 309 to move. When the first locking pin 308 and the second locking pin 309 are engaged in the corresponding positions... After being inserted into the first locking hole 301 and the second locking hole 302, the first connecting ring 201 and the second connecting ring 202 can be fixed. By fixing the first protective sleeve 203 at the bottom of both the first connecting ring 201 and the second connecting ring 202, the cooperation of the two sets of first protective sleeves 203 can prevent the operator from directly contacting the outer wall of the crucible furnace body 100, thereby preventing the operator from being burned. Since protective parts are provided at the top of both the first connecting ring 201 and the second connecting ring 202, the two sets of protective parts (receiving ring 205 and second protective sleeve 206) can increase the overall height of the crucible furnace body 100, thereby preventing the molten material from splashing out of the crucible furnace body 100 and ensuring the safety of surrounding equipment and personnel.

When one end of the threaded locking rod 312 disengages from the limiting hole 314, the telescopic rod 305 will be driven to stretch under the action of the spring 306. The telescopic rod 305 then drives the movable plate 304 to move within the movable groove 303. The movable plate 304 will then move the connecting plate 307, the first locking pin 308, and the second locking pin 309. When the first locking pin 308 and the second locking pin 309 are engaged with the first locking hole 301 and the second locking hole 302 respectively, the first connecting ring 201 and the second connecting ring 202 can be fixed. When disassembling the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206), the movable plate 304 is first moved within the movable groove 303. At this time, the spring 306 and the telescopic rod 305 will... During the retraction movement, the movable plate 304 moves, causing the connecting plate 307 to move. After the first locking pin 308 and the second locking pin 309 disengage from the first locking hole 301 and the second locking hole 302 respectively, the rotating wheel 313 drives the threaded locking rod 312 to move within the threaded hole 311. When one end of the threaded locking rod 312 engages with the limiting hole 314, the mounting assembly 300 (telescopic rod 305, spring 306, movable plate 304, connecting plate 307, first locking pin 308, second locking pin 309) is fixed, preventing the mounting assembly 300 from affecting the two sets of first protective sleeves 203 and the two... The disassembly of the protective components (receiving ring 205, second protective sleeve 206) causes an impact, and then the first connecting ring 201 and the second connecting ring 202 are driven to separate. After the first locking block 208 is disengaged from the first locking groove 207 and the second locking block 210 is disengaged from the second locking groove 209, the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205, second protective sleeve 206) can be disassembled. In summary, this utility model facilitates the installation and disassembly of the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205, second protective sleeve 206), and is relatively convenient to use.

[0020] In summary, please refer to the following: Figures 1-4First, engage the first locking block 208 and the second locking block 210 into the first locking slot 207 and the second locking slot 209 respectively. This will connect the first connecting ring 201 and the second connecting ring 202 to the outer wall of the crucible furnace body 100. Then, rotate the rotating wheel 313. The rotating wheel 313 will drive the threaded locking rod 312 to move in the threaded hole 311. When one end of the threaded locking rod 312 disengages from the limiting hole 314, the spring 306 will drive the telescopic rod 305 to perform a stretching movement. The telescopic rod 305 will then drive the movable plate 304 to move in the movable groove 303. The movable plate 304 will drive the connecting plate 307. The first locking pin 308 and the second locking pin 309 move, and when they engage with the first locking hole 301 and the second locking hole 302 respectively, the first connecting ring 201 and the second connecting ring 202 can be fixed. Because the bottom of both the first connecting ring 201 and the second connecting ring 202 is fixed with a first protective sleeve 203, the cooperation of the two sets of first protective sleeves 203 can prevent the operator from directly contacting the outer wall of the crucible furnace body 100, thus preventing burns. Since protective parts are provided at the top of both the first connecting ring 201 and the second connecting ring 202, the two... The protective components (receiving ring 205, second protective sleeve 206) can increase the overall height of the crucible furnace body 100, thereby preventing molten material from splashing out of the crucible furnace body 100 and ensuring the safety of surrounding equipment and personnel. When installing the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205, second protective sleeve 206), firstly, engage the first locking block 208 and the second locking block 210 into the first locking groove 207 and the second locking groove 209 respectively, then connect the first connecting ring 201 and the second connecting ring 202 to the outer wall of the crucible furnace body 100, and then rotate the rotating wheel 31. 3. The rotating wheel 313 will drive the threaded clamp 312 to move in the threaded hole 311. When one end of the threaded clamp 312 is disengaged from the limiting hole 314, the spring 306 will drive the telescopic rod 305 to stretch. The telescopic rod 305 will then drive the movable plate 304 to move in the movable groove 303. The movable plate 304 will drive the connecting plate 307, the first clamping post 308, and the second clamping post 309 to move. When the first clamping post 308 and the second clamping post 309 are engaged in the first clamping hole 301 and the second clamping hole 302 respectively, the first connecting ring 201 and the second connecting ring 202 can be fixed.When disassembling the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206), firstly, the movable plate 304 is moved within the movable groove 303. At this time, the spring 306 and the telescopic rod 305 will retract. When the movable plate 304 moves, it will drive the connecting plate 307 to move. After the first locking pin 308 and the second locking pin 309 are disengaged from the first locking hole 301 and the second locking hole 302 respectively, the rotating wheel 313 drives the threaded locking rod 312 to move within the threaded hole 311. When one end of the threaded locking rod 312 is engaged within the limiting hole 314, the installation assembly 300 (telescopic rod 305, spring 306, movable plate 304, connecting plate 307, first locking pin 306, second locking rod 307, and second locking rod 308) can be installed. 08. The second locking post 309 is fixed to prevent the installation component 300 from affecting the disassembly of the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206). Then, the first connecting ring 201 and the second connecting ring 202 are driven to separate. After the first locking block 208 is disengaged from the first locking groove 207 and the second locking block 210 is disengaged from the second locking groove 209, the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206) can be disassembled. In summary, this utility model facilitates the installation and disassembly of the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206), and is relatively convenient to use.

[0021] As can be seen from Embodiments 1 and 2, on the one hand, by fixing the first protective sleeve 203 to the bottom of both the first connecting ring 201 and the second connecting ring 202, the cooperation of the two sets of first protective sleeves 203 can prevent the operator from directly contacting the outer wall of the crucible furnace body 100, thereby preventing the operator from being burned; since protective components are provided at the top of both the first connecting ring 201 and the second connecting ring 202, the two sets of protective components (receiving ring 205 and second protective sleeve 206) can increase the overall height of the crucible furnace body 100, thereby preventing the molten material from splashing out of the crucible furnace body 100, ensuring the safety of surrounding equipment and personnel; on the other hand, it is convenient to install and disassemble the two sets of first protective sleeves 203 and the two sets of protective components (receiving ring 205 and second protective sleeve 206), making it more convenient to use.
