Description

Technical Field

[0001] The utility model relates to the technical field of anode copper casting, in particular to an emergency reset device for anode copper casting. Background Art

[0002] The anode copper casting equipment is a large-scale system equipment in the metallurgical industry. This equipment needs to be coordinated by multiple devices to complete the anode casting work. The anode copper casting equipment is mainly composed of a quantitative casting device, a tundish device, a spraying device, a die pressing and pre-lifting device, a waste anode device, a positive lifting device, an extractor device, a water tank, a driving device and other systems.

[0003] The molten copper liquid of the anode copper casting equipment is first continuously flowed from the furnace into the tundish through a fixed launder. When a certain amount of copper water is reached in the tundish, the copper water is poured into the casting ladle placed on the quantitative casting device. The weighing system continuously measures and weighs the injected copper water. When the copper water in the casting ladle reaches the set weight, the tundish automatically returns to the waiting position. When the empty mold on the disk stays at the casting position, the casting ladle starts to quantitatively cast copper water into the empty mold at the casting position at the same time. When the copper water in the mold reaches the single weight of the set anode plate, the casting ladle automatically returns to the waiting position, and the tundish injects a certain amount of copper water into the casting ladle. At the same time, the disk rotates one mold position, and the casting ladle quantitatively casts copper water into the next empty mold again. The casting system operates in such a cycle until the casting is completed.

[0004] However, the molten copper liquid cast by the anode copper casting equipment has a temperature of about 1200 °C. The temperature at the casting site is high, the water vapor is large, the on-site working conditions are complex, and the degree of automation of the equipment is high. Equipment failures are extremely likely to cause related accidents. Especially when the tundish and the casting ladle in the casting system fail, the tilting mechanism of the tundish and the casting ladle, which is similar to a cradle, pours out the copper liquid outward. If a power failure or other situations cannot be handled in a timely and effective manner, it will cause the molten copper liquid to overflow, leading to equipment and personnel injury accidents. Most copper smelting enterprises have experienced the above similar failures and accidents caused by the overflow of molten copper liquid. In view of this, an emergency reset device for anode copper casting is provided to overcome the above defects. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an emergency reset device for anode copper casting.

[0006] To achieve the above object, the utility model adopts the following technical solution: An emergency reset device for anode copper casting, comprising a PLC control cabinet and a casting ladle. The PLC control cabinet is electrically connected to a touch screen, a UPS power supply, an SLM rectification module, a servo driver, and a super capacitor. A hollow housing is fixedly connected to the rear of the top of the casting ladle. DC motors are fixedly connected to the left and right end faces of the hollow housing. A threaded rod is fixedly connected to the output end of the DC motor. A partition is rotatably connected to the inner top end of the threaded rod. A moving block is helically connected to the outer side of the threaded rod. A connecting rod is rotatably connected to the bottom of the moving block. The other end of the connecting rod is rotatably connected to a fixing plate. A solid ball is fixedly connected to the bottom of the fixing plate. A hollow ball is rotatably connected to the outer side of the solid ball.

[0007] As a further description of the above technical solution: The UPS power supply and the super capacitor supply power to the servo driver. The servo driver is electrically connected to the DC motor. The outer side of the partition is fixedly connected to the middle inside the hollow housing. The outer side of the moving block is slidably connected to the left and right sides inside the hollow housing. The outer side of the connecting rod is slidably connected to the middle below inside the hollow housing. The bottom of the hollow ball is fixedly connected to the top of the casting ladle, improving the safety performance of the anode copper casting equipment, increasing the reliability of the reset of the casting ladle and the tundish, eliminating the casting hidden dangers existing in the anode copper casting equipment, and reducing the failure rate of the equipment.

[0008] As a further description of the above technical solution: The casting ladle, the PLC control cabinet and all structures are integrated in the anode copper casting equipment. The number of the hollow housing, its internal structure, the solid ball and the hollow ball is two sets. The anode copper casting equipment is provided with a casting ladle and a tundish, and the hollow housing, its internal structure, the solid ball and the hollow ball are distributed above the casting ladle and above the tundish. When the anode copper casting equipment is working normally and the system suddenly loses power and the whole machine cannot continue to operate, the energy stored in the super capacitor and the UPS power supply provides a power source. Through the automatic setting of the PLC control cabinet and the transmission of the DC motor, the casting ladle and the tundish are automatically reset to the starting position.

[0009] As a further description of the above technical solution: The voltage of the UPS power supply is 380V, and the UPS power supply independently supplies power to the servo drivers of the tundish and the casting ladle. In the case of power failure of the system, in order to ensure the simultaneous reset of the tundish and the casting ladle, sufficient energy needs to be provided, and a UPS power supply with 380V power supply needs to be configured to independently supply power to the servo drivers of the tundish and the casting ladle.

[0010] As a further description of the above technical solution: The number of DC motors in the hollow housing is two, and the DC motors are distributed on the left and right sides of the hollow housing. The DC motor on the left side of the hollow housing drives the threaded rod to rotate clockwise, and the DC motor on the right side of the hollow housing drives the threaded rod to rotate counterclockwise. The DC motor can rotate forward and backward. When the servo driver drives the DC motor to start, the moving block on the outer side of the threaded rod moves inward, so that the casting ladle and the tundish are automatically reset. And during subsequent power supply, the DC motor rotates forward or backward together with the rotation of the casting ladle and the tundish.

[0011] As a further description of the above technical solution: A chute is provided in the middle of the bottom of the hollow housing, and the width of the chute in the middle of the bottom of the hollow housing matches the cross-sectional diameter of the connecting rod, which allows the moving block to drive the connecting rod to lift or retract the position of the solid ball together, realizing the reset operation of the casting ladle and the tundish in the case of power failure.

[0023] Referring to Figures 1-6 , an emergency reset device for anode copper casting provided by the present utility model includes a PLC control cabinet 1 and a casting ladle 7. The PLC control cabinet 1 is electrically connected to a touch screen 2, a UPS power supply 3, an SLM rectification module 4, a servo driver 5, and a super capacitor 6. A hollow housing 8 is welded to the rear of the top of the casting ladle 7. DC motors 9 are fixed to the left and right end faces of the hollow housing 8 by bolts. The output shaft of the output end of the DC motor 9 penetrates into the threaded rod 11 and is welded and fixed to the inside of the threaded rod 11. The inner top end of the threaded rod 11 is connected to the partition board 10 through a bearing. The threaded rod 11 penetrates through the inside of the moving block 12 and is screwed with the internal thread inside the moving block 12. The bottom of the moving block 12 is connected to the connecting rod 13 through a rotating shaft. The other end of the connecting rod 13 is connected to the fixed plate 14 through a rotating shaft. A solid ball 15 is welded to the bottom of the fixed plate 14. The outside of the solid ball 15 rotates and rotates in the hollow part inside the hollow ball 16. The UPS power supply 3 and the super capacitor 6 supply power to the servo driver 5. The servo driver 5 is electrically connected to the DC motor 9. The outside of the partition board 10 is fixedly connected to the middle inside the hollow housing 8. The outside of the moving block 12 is slidably connected to the left and right sides inside the hollow housing 8. The outside of the connecting rod 13 is slidably connected to the middle of the lower part inside the hollow housing 8. The bottom of the hollow ball 16 is fixedly connected to the top of the casting ladle 7, improving the safety performance of the anode copper casting equipment, increasing the reliability of the reset of the casting ladle 7 and the tundish, eliminating the casting hidden dangers existing in the anode copper casting equipment, and reducing the failure rate of the equipment.

[0024] As a further implementation of the above technical solution: The casting ladle 7, the PLC control cabinet 1 and all structures are integrated in the anode copper casting equipment. The number of the hollow shells 8, their internal structures, the solid balls 15 and the hollow balls 16 are both two sets. The anode copper casting equipment is provided with a casting ladle 7 and an intermediate ladle, and the hollow shells 8, their internal structures, the solid balls 15 and the hollow balls 16 are distributed above the casting ladle 7 and above the intermediate ladle. When the anode copper casting equipment is working normally and the system suddenly loses power and the whole machine cannot continue to operate, the energy stored in the super capacitor 6 and the UPS power supply 3 provides a power source. Through the automatic setting of the PLC control cabinet 1 and the transmission of the DC motor 9, the casting ladle 7 and the intermediate ladle are automatically reset to the starting position.

[0025] As a further implementation of the above technical solution: Since the number of super capacitors 6 that can be connected in parallel in the servo drive system is limited and is not enough to provide sufficient energy, in the case of power failure of the system, in order to ensure the simultaneous reset of the intermediate ladle and the casting ladle 7, sufficient energy needs to be provided. It is necessary to configure a UPS power supply 3 with V power supply to supply power to the servo drivers 5 of the intermediate ladle and the casting ladle 7 separately. The configured UPS power supply 3 and the SLM rectification module 4, the power supply of the intermediate ladle and the casting ladle 7 consists of: UPS power supply 3 + SLM rectification module 4 + servo driver 5 + super capacitor 6. When the system is working normally, the power supply supplies power to the SLM rectification module 4. When the system loses power, the transfer switch switches the power supply to the UPS power supply 3. After the transfer switch operates, the PLC control cabinet 1 automatically issues an instruction, and the intermediate ladle and the casting ladle 7 are reset to the initial state.

[0026] As a further implementation of the above technical solution: The number of DC motors 9 in the hollow shell 8 is two, and the DC motors 9 are distributed on the left and right sides of the hollow shell 8. The DC motor 9 on the left side of the hollow shell 8 drives the threaded rod 11 to rotate clockwise, and the DC motor 9 on the right side of the hollow shell 8 drives the threaded rod 11 to rotate counterclockwise. The DC motor 9 can rotate forward and backward. When the servo driver 5 drives the DC motor 9 to start, the moving block 12 outside the threaded rod 11 moves inward, so that the casting ladle 7 and the intermediate ladle are both automatically reset, and during subsequent power supply, the DC motor 9 rotates forward or backward together with the rotation of the casting ladle 7 and the intermediate ladle.

[0027] As a further implementation of the above technical solution: A chute is provided in the middle of the bottom of the hollow shell 8, and the width of the chute in the middle of the bottom of the hollow shell 8 matches the cross-sectional diameter of the connecting rod 13, which can be used for the moving block 12 to drive the connecting rod 13 to lift or retract the position of the solid ball 15 together, so as to realize the reset operation of the casting ladle 7 and the intermediate ladle in the case of power failure.

[0028] As a further implementation of the above technical solution: A groove is formed at the top of the hollow sphere 16, extending from the middle of the front side downward to the middle of the rear side downward, and the groove communicates with the hollow inside the hollow sphere 16. The bottom of the hollow sphere 16 is fixed at the rear position of the top of the ladle 7, allowing the solid sphere 15 to drive the fixed plate 14 to rotate forward and backward inside the hollow sphere 16 to adapt to any rotation angle of the ladle 7 and the tundish.

[0029] Working principle:

[0030] When using the present utility model, when the anode copper casting equipment is casting molten copper, the ladle 7 and the tundish need to pour by rotating the angle of the barrel body. When a power outage occurs during the pouring process of the ladle 7 and the tundish, the whole machine cannot continue to operate. At this time, the energy stored in the super capacitor 6 and the UPS power supply 3 provides the power source. Through the automatic setting of the PLC control cabinet 1, the SLM rectifier module 4 and the servo driver 5 start the DC motor 9. In order to ensure the simultaneous reset of the tundish and the ladle 7, sufficient energy needs to be provided. A UPS power supply 3 with V power supply is configured to supply power to the servo driver 5 of the tundish and the ladle 7 alone. At the same time, the configured UPS power supply 3 and the SLM rectifier module 4, the power supply composition of the tundish and the ladle 7 is: UPS power supply 3 + SLM rectifier module 4 + servo driver 5 + super capacitor 6. When the system is working normally, the power supply supplies power to the SLM rectifier module 4. When the system loses power, the switching switch switches the power supply to the UPS power supply 3. After the switching switch operates, the PLC control cabinet 1 automatically issues an instruction, and the DC motor 9 starts. The threaded rod 11 inside the hollow housing 8 rotates. At this time, the rotation direction of the threaded rod 11 drives the moving block 12 outside it to approach the left and right edges of the partition 10. At this time, the connecting rod 13 at the bottom of the moving block 12 drives the fixed plate 14 and the solid sphere 15 to extend downward. At this time, the solid sphere 15 drives the hollow sphere 16, the ladle 7 and the tundish to be pressed downward. At this time, the ladle 7 and the tundish are pressed from the original inclined state to the vertical state, preventing the molten copper in the ladle 7 and the tundish from continuing to pour and overflowing.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
