[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0025] A power failure protection device for a copper rod horizontal continuous casting machine in this embodiment relates to the technical field of copper rod continuous casting. When the power supply is normal, the gas storage tank 220 is provided with gas and the air pressure is maintained. After an emergency power failure, the gas storage tank 220 can inject gas into the cylinder 210, immediately driving the ladle 100 to pour the copper liquid outside the crystallization wheel to prevent the copper liquid from damaging the crystallization wheel.

[0026] See also Figures 1 to 4 In this embodiment, a power outage protection device for a copper rod horizontal continuous casting machine includes a ladle 100 and a pneumatic top extension assembly 200. The ladle 100 is used to store molten copper and pour it onto a crystallization wheel. The pneumatic top extension assembly 200 can use the high-pressure air stored before the power outage to drive the ladle 100 to dump after the power outage, discharge the molten copper to the outside, and prevent the crystallization wheel from being damaged by the molten copper.

[0027] One end of the ladle 100 is provided with a copper outlet 110, positioned opposite the crystallization wheel. Molten copper in the ladle 100 can overflow from the outlet 110 into the crystallization wheel. A copper inlet 120 is provided at the other end of the ladle 100. Molten copper from the copper smelting furnace is fed into the ladle 100 through the inlet 120. During operation, the ladle 100 is positioned horizontally. Molten copper from the inlet 120 is stored in the ladle 100. When the ladle 100 overflows, it overflows from the outlet 110 and pours into the crystallization wheel. The ladle 100 cushions the impact of the molten copper and protects the crystallization wheel.

[0028] The pneumatic extension assembly 200 includes a cylinder 210 and an air storage tank 220. The bottom of the ladle 100 is hinged to the base at one end opposite to the copper inlet 120. The cylinder 210 is arranged at the bottom of the ladle 100 at one end opposite to the copper outlet 110. The two ends of the cylinder 210 are respectively connected to the base and the ladle 100. The air storage tank 220 is connected to the cylinder 210 through a pipeline. The air storage tank 220 can supply air relative to the cylinder 210 when the power is off. The cylinder 210 is affected by the air pressure and relatively extended, which can drive the ladle 100 to tilt relative to the copper inlet 120 and pour the molten copper outward in the opposite direction to prevent the crystallization wheel from being damaged and destroyed by the molten copper.

[0029] In some embodiments, see Figure 1 The pneumatic extension assembly 200 also includes a valve 230, which is arranged on the pipeline between the gas tank 220 and the cylinder 210. After a power outage, the valve 230 can be fed open to connect the gas tank 220 and the cylinder 210. The high-pressure gas from the gas tank 220 can drive the cylinder 210 to extend, drive the ladle 100 to tilt relative to the copper inlet 120, and pour the molten copper outward in the opposite direction to prevent the stopped crystallization wheel from being damaged and destroyed by the molten copper.

[0030] As one embodiment, valve 230 is a normally open solenoid valve that remains closed when power is on and remains open when power is off. The normally open solenoid valve is arranged on the pipeline between the gas tank 220 and the cylinder 210. The normally open solenoid valve is always connected to the main circuit of the factory and remains energized. The normally open solenoid valve can open when power is lost, connecting the gas tank 220 and the cylinder 210, providing air pressure for the operation of the cylinder 210, thereby driving the ladle 100 to tilt relative to the copper inlet 120, pouring molten copper outward in the opposite direction, and preventing the shut-down crystallization wheel from being damaged or destroyed by the molten copper.

[0031] In another embodiment, valve 230 is a manual switching valve, which is installed on the pipeline between the gas storage tank 220 and the air cylinder 210 and is kept in a normally closed state. In the event of a temporary power outage, an operator quickly operates the manual switching valve manually, opening it and connecting the gas storage tank 220 with the air cylinder 210. This provides air pressure for the operation of the air cylinder 210, thereby driving the ladle 100 to tilt relative to the copper inlet 120 and pouring the molten copper outward in the opposite direction, thus preventing the idle crystallization wheel from being damaged or destroyed by the molten copper.

[0032] It should be noted that: since the ladle 100 storing molten copper is extremely heavy, the driving power of the ordinary air compressor 310 and the air tank 220 of the air compressor 310 is insufficient and may not be able to effectively extend the ladle 100. By setting up the air tank 220 and storing gas in the air tank 220, the volume of the high-pressure gas can be increased and the driving power can be improved. In addition, the volume of the air tank 220 is at least 1m 3 , at least 1m 3 The high-pressure gas is sufficient to drive the cylinder 210 to complete the overturning and dumping of the ladle 100.

[0033] In some embodiments, see Figure 1The power failure protection device of the copper rod horizontal continuous casting machine also includes an air supply component 300, which includes an air compressor 310. The air compressor 310 is connected to the air tank 220 through a pipeline. The air compressor 310 is driven by electricity and can be started intermittently to fill the air tank 220 with air, so that the air tank 220 always stores air and the air is maintained at the set air pressure, ready to supply air to the cylinder 210 at any time after a power outage.

[0034] In some embodiments, see Figure 1 The power outage protection device of the copper rod horizontal continuous casting machine also includes a molten copper emergency pool 400. The molten copper emergency pool 400 is located opposite the copper inlet 120 of the ladle 100 and has a volume greater than the maximum volume of the ladle 100. The molten copper emergency pool 400 can accommodate molten copper poured from the ladle 100 and can also temporarily receive molten copper from the copper smelting furnace.

[0035] In some embodiments, see Figures 2 to 4 An elastic buffer unit 240 is provided between the ladle 100 and the base, and one end of the elastic buffer unit 240 is fixedly connected to the base. When the ladle 100 is working normally, the cylinder 210 remains in a contracted state, and the other end of the elastic buffer unit 240 abuts against the ladle 100, bearing the weight of the ladle 100, reducing the load of the cylinder 210, and avoiding the cylinder 210 from pushing the cylinder accident. After the cylinder 210 pushes the ladle 100 to pour the molten copper, as the air pressure slowly decreases, or the pressure is manually reduced, the ladle 100 needs to be reset and restarted after the power supply is restored. The elastic buffer unit 240 can cushion the falling ladle 100 to prevent the ladle 100 from serious collision and impact under the action of inertia.

[0036] It should be noted that the elastic buffer unit 240 is specifically an air buffer cylinder 210, which has supporting and buffering functions.

[0037] In some embodiments, see Figure 3 and Figure 4 A hinge structure is provided between the base and the bottom end of the ladle 100, facing the copper inlet 120. The hinge structure comprises two hinged plates, with their opposing ends fixedly connected to the ladle 100 and the base, respectively. Their facing ends are hinged via a hinge axis. The combined length of the two hinged plates, when overlapped, matches the minimum length of the elastic buffer unit 240. During normal use, the elastic buffer unit 240 and the hinge structure jointly support the ladle 100, keeping it level.

[0038] Workflow: During normal power supply use, please refer to Figure 3The ends of the ladle 100 are supported by elastic buffer units 240 and hinge structures, respectively. The ends of the cylinder 210 are also hinged to the ladle 100 and the base. The air compressor 310 operates intermittently to maintain the gas pressure in the gas tank 220. Molten copper from the copper smelting furnace enters the crystallization wheel through the ladle 100.

[0039] After a power outage, please refer to Figure 4 , the crystallization wheel stops running, the valve 230 located between the gas tank 220 and the cylinder 210 is opened, and the high-pressure gas from the gas tank 220 is input into the cylinder 210. The cylinder 210 drives the ladle 100 to tilt relative to the copper inlet 120, and pours the molten copper outward in the opposite direction to prevent the stopped crystallization wheel from being damaged and destroyed by the molten copper.

[0040] The above description is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the present invention.
