Description

Technical Field

[0001] This invention relates to the field of metal smelting technology, and in particular to a device and method for replacing the inductor of an industrial frequency electric furnace without shutting down the furnace. Background Technology

[0002] Zinc smelting commonly uses an industrial frequency cored electric furnace for melting and casting zinc sheets. When the inductor malfunctions and leaks zinc, it needs to be removed and replaced. During the replacement process, the molten zinc in the furnace needs to be emptied before replacement. Disadvantages include: long replacement cycle, high labor intensity for personnel, low start-up rate, inventory backlog, and problems such as using natural gas to melt zinc ingots when resuming production.

[0003] According to Chinese Patent Publication No. CN210980773U, an auxiliary device for replacing the inductor in an industrial frequency induction furnace is disclosed, relating to the field of metal smelting technology. It includes a water jacket, an inlet pipe, and an outlet pipe, with the inlet and outlet pipes mounted on the water jacket. A lifting device connected to the water jacket is also included. The lifting device is used to insert the water jacket along the inner wall of the furnace to the front of the inductor. Circulating cold water is passed through the water jacket to lower the temperature of the molten zinc around the inductor inside the furnace, causing the surrounding zinc to solidify and form a natural seal with the furnace wall. This facilitates the replacement of the inductor without affecting the normal operation of the other inductor. Compared to traditional methods, this eliminates the step of scooping out molten zinc, reducing labor intensity, maintenance and replacement time, and saving costs.

[0004] The aforementioned patent has the advantages of reducing labor intensity, reducing maintenance and replacement time, and saving costs. However, after the inductor malfunctions and leaks zinc, it needs to be removed and replaced. During the replacement process, the zinc liquid in the furnace needs to be emptied before replacement. The disadvantages are: long replacement cycle, high labor intensity for personnel, low start-up rate, inventory backlog, and problems such as using natural gas to melt zinc ingots when resuming production. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for replacing the inductor of an industrial frequency electric furnace without shutting down the furnace. This device solves the problem of not needing to clean the zinc liquid inside the furnace, allowing for direct power-on production after replacement, shortening replacement time, eliminating the need to rebuild the molten pool, improving the overall working efficiency of the device, and facilitating the observation of the liquid level inside the furnace.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a device for replacing the inductor of an industrial frequency electric furnace without shutting down the furnace, comprising a furnace body, a zinc ingot opening on one side of the furnace body, an L-shaped rod fixedly connected to the outer surface of the furnace body, a first cylinder fixedly connected to the upper surface of the L-shaped rod, a first telescopic rod fixedly connected to the output end of the first cylinder, a U-shaped rod fixedly connected to the outer surface of the first cylinder, a second cylinder fixedly connected to the lower surface of the U-shaped rod, a second telescopic rod fixedly connected to the output end of the second cylinder, a clamping ring fixedly connected to the lower surface of the second telescopic rod, and a soft pad provided on the outer surface of the clamping ring.

[0007] By adopting the above technical solution, after the inductor leaks, the user cleans the zinc slag in the furnace, adjusts the second switch to lower the liquid level to be level with the inductor's melting channel opening, and waits for the zinc slurry temperature in the furnace to drop to a certain degree. The user then drives the first cylinder to extend and retract the first telescopic rod, which in turn moves the soft zinc ingot container. The soft zinc ingot container then inserts the zinc ingot delivery pipe into the furnace through the zinc ingot opening. The user first opens the first switch, then drives the second cylinder to extend and retract the second telescopic rod, which in turn moves the clamping ring up and down. There are two second cylinders. The soft pad presses down the soft zinc ingot container, causing the zinc slurry inside to flow into the melting channel opening of the leaking inductor. This allows the zinc ingot to be added, causing the zinc slurry in the leaking inductor's melting channel opening to solidify quickly. At the same time, the normal inductor remains in a low-speed operation and its melting channel does not solidify. After adding an appropriate amount of zinc ingot and waiting for half of the volume in the furnace to solidify, the faulty inductor can be removed.

[0008] A further provision of the present invention is that: a soft zinc ingot container is provided on the outer surface of the soft pad, and a zinc ingot conveying pipe is provided on the outer surface of the soft zinc ingot container.

[0009] By adopting the above technical solution, the user turns the handle to drive the sealing block to rotate, and the sealing block drives the bolt to disengage from the screw hole, thereby disengaging from the sensor.

[0010] A further feature of the present invention is that a first switch is provided on the outer surface of the zinc ingot conveying pipe, and an insertion hole is provided on the outer surface of the furnace body.

[0011] By adopting the above technical solution, after all the bolts are removed, the crane can lift it off. If lifting is difficult and the inductor can still be powered, the connection between the inductor and the furnace body can be melted by powering on the inductor.

[0012] A further feature of the present invention is that a sealing block is inserted into the inner wall of the insertion hole, an inductor is provided inside the furnace body, a screw hole is provided on the outer surface of the inductor, a bolt is fixedly connected to the outer surface of the sealing block, and the outer surface of the bolt is threadedly connected to the inner wall of the screw hole.

[0013] By adopting the above technical solution, the power cord can be immediately removed and the device lifted after the process is observed to be detachable. After lifting, the connection parts are processed, smoothed, and a new sensor is replaced. The replacement can generally be completed within an hour.

[0014] A further feature of the present invention is that a vertical rod is fixedly connected to the upper surface of the sealing block, and a handle is fixedly connected to the outer surface of the vertical rod.

[0015] By adopting the above technical solution, after the replacement is completed, the good inductor increases its speed to melt the solidified zinc in the furnace. After the zinc solution enters the replaced inductor, the replaced inductor is powered on and gradually increases its speed to normal production, thereby improving the overall working efficiency of the device.

[0016] A further feature of the present invention is that an anti-slip pad is fixedly connected to the outer surface of the handle, and scale lines are provided on the outer surface of the furnace body.

[0017] By adopting the above technical solution, the anti-slip pad on the handle makes it easier to remove the bolts, and the scale lines make it easier for users to observe the changes in the liquid level inside the furnace.

[0018] A further feature of the present invention is that a liquid outlet pipe is provided on one side of the furnace body, and a second switch is provided on the outer surface of the liquid outlet pipe.

[0019] By adopting the above technical solution, the liquid outlet pipe can easily lower the liquid level to be level with the inlet of the sensor, thus improving the overall convenience of the device.

[0020] A further feature of the present invention is that a support is fixedly connected to the lower surface of the furnace body, and a pulley is fixedly connected to the lower surface of the support.

[0021] By adopting the above technical solution, the pulley makes it easy for the user to move this device.

[0022] A method for using a device for replacing the inductor of a power frequency electric furnace without shutting down the furnace includes the following steps: Step 1: First, after the inductor leaks, clean the zinc liquid slag inside the furnace. Adjust the second switch on the outer surface of the outlet pipe to lower the liquid level to the level of the inductor's melting channel. When the temperature of the zinc liquid inside the furnace drops to a certain degree, drive the first cylinder to extend and retract the first telescopic rod. The first telescopic rod moves the soft zinc ingot container. The soft zinc ingot container moves the zinc ingot conveying pipe on its outer surface and inserts it into the furnace from the zinc ingot opening on one side of the furnace. First, open the first switch. Step Two: Then, drive the second cylinder to extend and retract the second telescopic rod. The second telescopic rod drives the clamping ring to move up and down. There are two second cylinders. The soft pad on the outer surface of the clamping ring presses down on the soft zinc ingot container, so that the zinc liquid in the soft zinc ingot container flows into the melting channel of the leaking inductor. Then, zinc ingots are put in to make the zinc liquid in the melting channel of the leaking inductor solidify quickly. At the same time, the normal inductor keeps running at a low speed and the melting channel does not solidify. After an appropriate amount of zinc ingots are put in, after half of the volume in the furnace has solidified, the faulty inductor can be removed. Step 3: Next, turn the handle. The handle is fixed to the outer surface of the vertical rod. The handle drives the sealing block to rotate. The sealing block drives the bolts fixed to its outer surface to disengage from the screw holes on the outer surface of the inductor body, thus separating it from the inductor body. After all the bolts are removed, the crane will lift it away. If it is difficult to lift it away and the inductor body can still be powered, the power will be turned on to melt the part where the inductor body is connected to the furnace body. During the process, observe that it can be separated. Immediately after that, disconnect the power cord and lift it away. After lifting it away, process the connection part, grind it smooth and replace it with a new inductor body. Step 4: Finally, after the replacement is completed, the good inductor increases its power level to melt the solidified zinc in the furnace. After the zinc solution enters the replaced inductor, the replaced inductor is powered on and gradually increased to normal production.

[0023] The beneficial effects of this invention are: 1. This invention, through the coordinated arrangement of the furnace body, zinc ingot inlet, L-shaped rod, first cylinder, first telescopic rod, U-shaped rod, second cylinder, second telescopic rod, clamping ring, and soft pad, enables the device to function effectively. In the event of leakage from the inductor, the user cleans the zinc molten slag from the furnace body, adjusts the second switch to lower the liquid level to the level of the inductor's melting channel, and waits for the zinc molten molten slurry temperature to drop. Then, the user drives the first cylinder to extend or retract the first telescopic rod, which in turn moves the soft zinc ingot container. The soft zinc ingot container then moves the zinc ingot conveying pipe from the zinc ingot... The inlet is inserted into the furnace body. The user first turns on the first switch, then drives the second cylinder to extend and retract the second telescopic rod. The second telescopic rod drives the clamping ring to move up and down. There are two second cylinders. The soft pad presses down the soft zinc ingot container, so that the zinc ingot liquid inside flows into the melting channel of the leaking inductor. Then, zinc ingots are added to quickly solidify the zinc liquid in the melting channel of the leaking inductor. At the same time, the normal inductor keeps running at a low speed and the melting channel does not solidify. After adding an appropriate amount of zinc ingots, once half of the volume inside the furnace has solidified, the faulty inductor can be removed.

[0024] 2. This invention, through the coordinated arrangement of the soft zinc ingot container, zinc ingot conveying pipe, first switch, insertion hole, sealing block, inductor, screw hole, bolt, vertical rod, and handle, allows the user to rotate the handle during use, causing the sealing block to rotate. The sealing block then causes the bolt to disengage from the screw hole, thereby detaching from the inductor. After all bolts are removed, a crane can lift it off. If lifting is difficult and the inductor can still be powered, the connection between the inductor and the furnace body can be melted by applying electricity. During the process, once separation is observed, the power cord is immediately disconnected and the inductor is lifted off. After lifting, the connection area is cleaned, smoothed, and a new inductor is replaced. Replacement can generally be completed within an hour. After replacement, the new inductor increases its speed to melt the solidified zinc in the furnace. The zinc solution enters the replaced inductor, which is then powered on and gradually increased to normal production, thus improving the overall working efficiency of the device.

[0025] 3. The present invention, through the coordinated arrangement of anti-slip pads, scale lines, liquid outlet pipes, second switches, brackets, and pulleys, enables the device to be used in a way that makes it easier to remove bolts with the anti-slip pads on the handles, facilitates the user's observation of the liquid level changes in the furnace, makes it easier to lower the liquid level to the level of the inductor, thus improving the overall convenience of the device, and makes it easier for the user to move the device.

[0030] Reference Figure 1-6A device for replacing the inductor of an industrial frequency electric furnace without shutting down the furnace includes a furnace body 1. A zinc ingot inlet 2 is opened on one side of the furnace body 1. An L-shaped rod 3 is fixedly connected to the outer surface of the furnace body 1. A first cylinder 4 is fixedly connected to the upper surface of the L-shaped rod 3. A first telescopic rod 5 is fixedly connected to the output end of the first cylinder 4. A U-shaped rod 26 is fixedly connected to the outer surface of the first cylinder 4. A second cylinder 6 is fixedly connected to the lower surface of the U-shaped rod 26. A second telescopic rod 7 is fixedly connected to the output end of the second cylinder 6. A clamping ring 8 is fixedly connected to the lower surface of the second telescopic rod 7. A soft pad 20 is provided on the outer surface of the clamping ring 8. After leakage of the inductor 15, the user cleans the zinc slag inside the furnace body 1, adjusts the second switch 22 to lower the liquid level to be level with the inductor 15's melting channel opening, and waits until the temperature of the zinc molten metal inside the furnace body 1 drops to 360 degrees Celsius. The user then drives the first cylinder 4 to extend and retract the first telescopic rod 5. The flexible zinc ingot container 9 moves, causing the zinc ingot conveying pipe 10 to be inserted into the furnace body 1 through the zinc ingot port 2. The user first turns on the first switch 11, then drives the second cylinder 6 to extend and retract the second telescopic rod 7. The second telescopic rod 7 causes the clamping ring 8 to move up and down. There are two second cylinders 6. The soft pad 20 presses down the flexible zinc ingot container 9, causing the molten zinc inside to flow into the melting channel of the leaking sensor 15. This allows the zinc ingot to be added, causing the molten zinc in the melting channel of the leaking sensor 15 to solidify quickly. At the same time, the normal sensor 15 remains in a low-speed operation and the melting channel does not solidify. After adding an appropriate amount of zinc ingots, once half of the volume inside the furnace body 1 has solidified, the faulty sensor 15 can be removed. The flexible zinc ingot container 9 is installed on the outer surface of the soft pad 20, the zinc ingot conveying pipe 10 is installed on the outer surface of the flexible zinc ingot container 9, and the first switch 11 is installed on the outer surface of the zinc ingot conveying pipe 10.A socket 12 is provided on the outer surface of the furnace body 1. A sealing block 13 is inserted into the inner wall of the socket 12. An inductor 15 is installed inside the furnace body 1. A screw hole 16 is provided on the outer surface of the inductor 15. A bolt 14 is fixedly connected to the outer surface of the sealing block 13. The outer surface of the bolt 14 is threaded to the inner wall of the screw hole 16. A vertical rod 17 is fixedly connected to the upper surface of the sealing block 13. A handle 18 is fixedly connected to the outer surface of the vertical rod 17. When the user turns the handle 18, the sealing block 13 rotates, causing the bolt 14 to disengage from the screw hole 16, thereby disengaging from the inductor 15. After all bolts 14 are removed, a crane is used to lift it off. If lifting is difficult and the inductor 15 can still be powered, electricity can be applied to melt the connection between the inductor 15 and the furnace body 1. During the process, observe that it can be separated, immediately disconnect the power cord and lift it off. After lifting, the connection area is cleaned, ground smooth, and a new inductor 15 is replaced. Replacement can generally be completed within 24 hours. After replacement, the new sensor 15 increases its speed to melt the solidified zinc inside the furnace body 1. The zinc solution enters the replaced sensor 15, which is then powered on and gradually increases its speed to normal production, improving the overall efficiency of the device. The handle 18 has an anti-slip pad 19 fixedly attached to its outer surface. The furnace body 1 has graduation lines 25 on its outer surface. A liquid outlet pipe 21 is located on one side of the furnace body 1, and a second switch 22 is located on the outer surface of the liquid outlet pipe 21. A bracket 23 is fixedly attached to the lower surface of the furnace body 1, and a pulley 24 is fixedly attached to the lower surface of the bracket 23. The anti-slip pad 19 on the handle 18 makes it easier to remove the bolt 14. The graduation lines 25 allow users to observe the liquid level changes inside the furnace body 1. The liquid outlet pipe 21 allows the liquid level to be lowered to the level of the sensor 15's melting channel, improving the overall ease of use. The pulley 24 facilitates the user's movement of the device.

[0031] Please refer to this carefully. Figure 1-4 A method for using a device for replacing the inductor of an industrial frequency electric furnace without shutting down the furnace includes the following steps: Step 1: First, after the leakage of the inductor 15, clean the zinc liquid scum inside the furnace body 1, adjust the second switch 22 set on the outer surface of the liquid outlet pipe 21 to lower the liquid level to be level with the melting channel opening of the inductor 15, and when the temperature of the zinc liquid inside the furnace body 1 drops to 360 degrees, drive the first cylinder 4 to drive the first telescopic rod 5 to extend and retract, the first telescopic rod 5 drives the soft zinc ingot container 9 to move, and the soft zinc ingot container 9 drives the zinc ingot conveying pipe 10 set on its outer surface to be inserted into the furnace body 1 from the zinc ingot opening 2 on one side of the furnace body 1. First, open the first switch 11. Step 2: Then, drive the second cylinder 6 to extend and retract the second telescopic rod 7. The second telescopic rod 7 drives the clamping ring 8 to move up and down. There are two second cylinders 6. The soft pad 20 on the outer surface of the clamping ring 8 presses down the soft zinc ingot container 9, so that the zinc liquid in the soft zinc ingot container 9 flows into the melting channel of the leaking inductor 15. Then, zinc ingots are put in to make the zinc liquid in the melting channel of the leaking inductor 15 solidify quickly. At the same time, the normal inductor 15 keeps running at a low speed and the melting channel does not solidify. After an appropriate amount of zinc ingots are put in, after half of the volume in the furnace body 1 has solidified, the faulty inductor 15 can be removed. Step 3: Next, rotate handle 18. Handle 18 is fixedly connected to the outer surface of vertical rod 17. Handle 18 drives sealing block 13 to rotate. Sealing block 13 drives bolt 14 fixedly connected to its outer surface to disengage from screw hole 16 on outer surface of inductor 15, thereby disengaging inductor 15. After all bolts 14 are removed, crane is used to lift it away. If lifting is difficult and inductor 15 can still be powered, power is supplied to melt the part where inductor 15 is connected to furnace body 1. During the process, observe that it can be separated and immediately disconnect the power line and lift it away. After lifting away, process the connection part, grind it flat and replace it with a new inductor 15. Step 4: Finally, after the replacement is completed, the good inductor 15 increases its power level to melt the solidified zinc in the furnace body 1. After the zinc solution enters the replaced inductor 15, the replaced inductor 15 is powered on and gradually increases its power level to normal production.

[0032] In this invention, through the coordinated arrangement of the furnace body 1, zinc ingot opening 2, L-shaped rod 3, first cylinder 4, first telescopic rod 5, U-shaped rod 26, second cylinder 6, second telescopic rod 7, clamping ring 8, and soft pad 20, the device can, during use, after leakage of the sensor 15, allow the user to clean the zinc liquid scum inside the furnace body 1, adjust the second switch 22 to lower the liquid level to be level with the melting channel opening of the sensor 15, and wait until the temperature of the zinc liquid inside the furnace body 1 drops to 360 degrees Celsius. The user then drives the first cylinder 4 to extend or retract the first telescopic rod 5, which in turn moves the soft zinc ingot container 9. The soft zinc ingot container 9 then moves the zinc ingot delivery pipe 10 from the zinc ingot opening 2 into the furnace body 1. First, turn on the first switch 11. Then, drive the second cylinder 6 to extend and retract the second telescopic rod 7. The second telescopic rod 7 drives the clamping ring 8 to move up and down. There are two second cylinders 6. The soft pad 20 presses down the soft zinc ingot container 9, causing the molten zinc inside to flow into the melting channel of the leaking sensor 15. This allows zinc ingots to be added, causing the molten zinc in the melting channel of the leaking sensor 15 to solidify quickly. At the same time, the normal sensor 15 remains in a low-speed operation and the melting channel does not solidify. After adding an appropriate amount of zinc ingots, once half of the volume inside the furnace body 1 has solidified, the faulty sensor 15 can be removed. The process involves the soft zinc ingot container 9, the zinc ingot conveying pipe 10, the first switch 11, the insertion hole 12, and the sealing block 13. The fitting arrangement between the inductor 15, screw hole 16, bolt 14, vertical rod 17, and handle 18 allows the user to rotate the handle 18 during use, causing the sealing block 13 to rotate. The sealing block 13 then disengages the bolt 14 from the screw hole 16, thus separating it from the inductor 15. After all bolts 14 are removed, a crane can lift it off. If lifting is difficult and the inductor 15 can still be powered, the connection between the inductor 15 and the furnace body 1 can be melted. During the process, observe that separation is possible, immediately disconnect the power cord and lift it off. After lifting, the connection area should be cleaned, smoothed, and a new inductor 15 replaced. Replacement is generally completed within 24 hours. After replacement, a good inductor... The inductor 15 is upgraded to melt the solidified zinc inside the furnace body 1. After the zinc solution enters the replacement inductor 15, the replacement inductor 15 is powered on and gradually upgraded to normal production, which improves the overall working efficiency of the device. Through the coordinated arrangement of the anti-slip pad 19, scale line 25, liquid outlet pipe 21, second switch 22, bracket 23, and pulley 24, the anti-slip pad 19 on the handle 18 makes it easier to remove the bolt 14 when using the device. The scale line 25 makes it easy for the user to observe the liquid level changes inside the furnace body 1. The liquid outlet pipe 21 makes it easy to lower the liquid level to be level with the melting channel of the inductor 15, which improves the overall convenience of the device. The pulley 24 makes it easy for the user to move the device.

The sealing block (13) drives the bolt (14) fixedly connected to its outer surface to disengage from the screw hole (16) on the outer surface of the inductor (15), thereby disengaging from the inductor (15). After all the bolts (14) are removed, the crane lifts it away. If it is difficult to lift away and the inductor (15) can still be powered, the part connecting the inductor (15) to the furnace body (1) is melted by power. During the process, observe that it can be separated and immediately disconnect the power line and lift it away. After lifting away, process the connection part, grind it flat and replace it with a new inductor (15). Step 4: Finally, after the replacement is completed, the good inductor (15) increases the gear to melt the solidified zinc in the furnace body (1). After the zinc solution enters the replaced inductor (15), the replaced inductor (15) is powered on and gradually increases the gear to normal production.
