Technical Field

[0001] The present invention relates to the technical field of non-ferrous metal processing, and particularly to an energy-saving and efficiency-increasing treatment method for the raw materials of a copper rod vertical furnace. Background Art

[0002] The raw materials used in a copper rod vertical furnace are generally bundled copper plates. In the prior art, when producing copper rods, it is necessary for a forklift driven by a worker to transport the copper plates from the storage yard to the feeding area in the workshop. After multiple transfers, the feeding machine is used for feeding. This link not only consumes a large amount of manpower, but also has low operation efficiency. At the same time, due to the relatively harsh working environment and many risk factors, using a large amount of manpower easily leads to production accidents; in the link of melting copper plates, because the copper plates are closely attached to each other and have small gaps, it is difficult for heat to conduct, the melting efficiency is low, resulting in high gas consumption, so it is not conducive to energy conservation and emission reduction. Summary of the Invention

[0006] Among them, in the above Step 2, a manual forklift stacks the copper plates at the input end of the first conveyor line of the energy-saving and efficiency-increasing treatment production line, uses the hydraulic centering mechanism on the first conveyor line for centering, then transports the stack of copper plates to the lifting scale, the lifting scale weighs and records the tare weight, then removes the bundling steel belt of the stack of copper plates, and finally the lifting scale weighs the stack of copper plates again and records the net weight;

[0007] Among them, in the above Step 3, the first conveyor line transports the stack of copper plates after removing the steel belt to the unstacking station, and the unstacking equipment splits the stack of copper plates into single copper plates and places them on the second conveyor line;

[0009] Among them, in the above Step 5, the second conveyor line transports the indented and bent copper plates to the second stacking platform for waiting for transfer. The transfer methods include the following two: one is to transfer by forklift to offline storage, and the other is to stack by the lifting stack transporter to the third stacking platform for waiting for subsequent production;

[0010] In the above step six, after the copper plates on the third stacking table are stacked to the set height, they are conveyed to the third conveyor line. The third conveyor line conveys the copper plates to the traversable chain conveyor, and the traversable chain conveyor conveys the copper plates to the hopper of the feeder.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the attached Figure 1 - attached Figure 2 , an embodiment provided by the present invention: a method for energy-saving and efficiency-increasing treatment of raw materials for a copper rod shaft furnace, including the following steps: Step 1, arranging the production line; Step 2, weighing and removing the steel strip; Step 3, unstacking the copper plates; Step 4, indentation and bending; Step 5, intermediate transportation; Step 6, automatic feeding;

[0026] Among them, in the above Step 1, an energy-saving and efficiency-increasing treatment production line is arranged in the feeding area of the raw materials for the copper rod shaft furnace. The energy-saving and efficiency-increasing treatment production line includes a first conveyor line 1, a lifting scale 11, a steel strip cutting manipulator 12, a steel strip pressing machine 13, a cleaning device 14, a suction cup manipulator 2, a pushing manipulator 21, a first stacking table 22, a second conveyor line 23, a hydraulic pressing machine 3, a second stacking table 4, a lifting stacking transport machine 5, a third stacking table 6, a third conveyor line 7, a horizontally movable chain conveyor 8, and a feeder hopper 9; the specific method for arranging the energy-saving and efficiency-increasing treatment production line is: arranging the lifting scale 11, the steel strip cutting manipulator 12, and the cleaning device 14 on the first conveyor line 1, arranging the suction cup manipulator 2, the pushing manipulator 21, and the first stacking table 22 at the output end of the first conveyor line 1, arranging the second conveyor line 23 on one side of the first stacking table 22, arranging the hydraulic pressing machine 3 on the second conveyor line 23, arranging the second stacking table 4 at the output end of the second conveyor line 23, arranging the lifting stacking transport machine 5 on one side of the second stacking table 4, arranging the third stacking table 6 at the output end of the lifting stacking transport machine 5, arranging the third conveyor line 7 on one side of the third stacking table 6, arranging the horizontally movable chain conveyor 8 at the output end of the third conveyor line 7, and arranging the feeder hopper 9 at the output end of the horizontally movable chain conveyor 8. Among them, a hydraulic centering mechanism is provided at the input end of the first conveyor line 1, and a steel strip pressing machine 13 is provided on one side of the steel strip cutting manipulator 12;

[0027] In the above step two, the manual forklift stacks the copper plates at the input end of the first conveyor line 1 of the energy-saving and efficiency-enhancing treatment production line, aligns them using the hydraulic centering mechanism on the first conveyor line 1, and then transports the stack of copper plates to the lifting scale 11. The lifting scale 11 weighs and records the tare weight, then removes the bundling steel strips of the stack of copper plates, and finally the lifting scale 11 weighs the stack of copper plates again and records the net weight. Among them, removing the bundling steel strips includes two methods: machine removal and manual removal. For machine removal, the steel strip shear manipulator 12 identifies the steel strip through machine vision, then uses the hydraulic cylinder to drive the blade to insert into the gap between the lowermost copper plate and the steel strip, and cuts off various forms of bundling steel strips forcefully along the diagonal direction of the copper plate at one time. Then, the steel strip is sucked by the magnet suction cup, and after being withdrawn, it is put into the steel strip briquetting machine 13. When the set quantity is accumulated, briquetting treatment is carried out. For manual removal, when the machine removal fails, the steel strip is manually cut and collected by workers. After removing the bundling steel strips, the copper plates are purged using the cleaning device 14, and the dust and floating rust cleared are collected through the negative pressure suction system.

[0028] In the above step three, the first conveyor line 1 transports the stack of copper plates after removing the steel strips to the unstacking station, and the unstacking equipment splits the stack of copper plates into single copper plates and places them on the second conveyor line 23. The unstacking equipment consists of a suction cup manipulator 2, a pushing manipulator 21, and a first stacking table 22. For single-style copper plates, the suction cup manipulator 2 sucks the upper copper plate and places it on the second conveyor line 23. For folded-style copper plates, the upper copper plate is pushed out. The first stacking table 22 rises successively, and the pushing manipulator 21 successively pushes the upper copper plate onto the second conveyor line 23.

[0029] In the above step four, the split copper plates are transported by the second conveyor line 23 into the hydraulic profiling machine 3, and the split copper plates are subjected to indentation and bending. The indentation and bending adopt the form of the lower stamping die moving upward and the upper stamping die being fixed. The lower stamping die lifts the copper plate to contact the upper stamping die to form corrugations. The indentation and bending include the following two methods: one is to bend each copper plate, and the other is intermittent indentation and bending. Intermittent indentation and bending is to perform partial indentation and bending on the copper plates in the same bundle according to a set ratio.

[0030] In the above step five, the second conveyor line 23 transports the copper plates after indentation and bending to the second stacking table 4 for transfer. The transfer methods include the following two: one is to be transported by a forklift to off-line storage, and the other is to be stacked by the lifting stacker transporter 5 onto the third stacking table 6 and wait for subsequent production.

[0031] In the above step six, when the copper plates on the third stacking table 6 are stacked to a set height, they are transported to the third conveyor line 7. The third conveyor line 7 transports the copper plates to the translatable chain conveyor 8. The translatable chain conveyor 8 transports the copper plates to the hopper of the feeding machine 9. Among them, the translatable chain conveyor 8 can move horizontally to switch positions, so as to avoid the forklift and facilitate the feeding of other raw materials.

[0032] Based on the above, the advantages of the present invention are as follows. When the invention is used, in terms of handling and feeding, an automated production line operation is adopted, which greatly reduces the use of labor and forklifts, reduces the labor cost, improves the working environment, and reduces potential accident hazards. Through the design of automated feeding, the feeding process is more closely connected and the operation is more precise, thus improving the feeding efficiency, ensuring the continuous and stable operation of the production line, and increasing the overall production capacity. By performing indentation and bending on the copper plates, the gap between the copper plates is artificially increased. In the copper plate melting process, the heat conduction in the furnace is smoother, the melting speed is accelerated, the fuel consumption is reduced, and the single fuel consumption of the shaft furnace is reduced by 1.5 - 2m 3 / t, effectively solving the problems of low copper plate melting efficiency and high gas consumption. Moreover, the bent copper plates do not require the use of U-shaped hoppers during feeding, reducing the weight of the hopper by about 1t, reducing the load of the feeder during upward and downward movement, thereby reducing power consumption, facilitating energy conservation and emission reduction, and alleviating the pressure on the enterprise in terms of energy-saving transformation.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed by the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
