Description

Technical Field

[0001] This utility model relates to the field of metallurgical production technology, specifically to a shell-breaking device for hot steel ladles used in copper smelting. Background Technology

[0002] In the copper synthesis furnace of the non-ferrous metallurgical industry, in the bottom-blown furnace + converter + anode furnace, matte is transferred to the ladle using a molten metal crane. Due to the high grade of the synthesis furnace and bottom-blown furnace, the matte becomes sticky during the hoisting process after being discharged into the ladle. Upon contact with air, it slowly cools and forms a crust. When the matte is added to the PS converter, it only flows out from the ladle nozzle, while the rest of the ladle is completely crusted. After the empty ladle is heated, it is transferred back to the front of the copper synthesis furnace for discharge again. Because of the crust on the top of the ladle, the molten metal washes over the crust surface during copper discharge and sprays outwards, falling into the adjacent ladle room. The sprayed matte increases with the number of discharges, which subsequently affects the normal operation of the ladle car. At the same time, the working environment is harsh and the labor intensity is high when the ladle room is cleaned manually every week. Utility Model Content

[0003] This invention provides a shell-breaking device for hot steel ladles in copper smelting to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A shell-breaking device for hot steel ladles in copper smelting includes a machine body, a furnace door on the side of the machine body, a hammer box movably mounted on the bottom of the outer wall of the machine body, a hammer tip at the bottom of the hammer box, a gearbox and a clutch on the bottom of the inner side of the machine body, a trolley on the inner wall of the machine body, and multiple guide rails on the side wall of the furnace door, with the trolley and guide rails slidably connected. Both the gearbox and the trolley are connected to a PLC controller.

[0005] Furthermore, the hammer box is equipped with a counterweight iron block, and the bottom of the hammer box is surrounded by a splash guard, which covers the hammer tip.

[0006] Furthermore, a chain is vertically installed inside the machine body, with both ends of the chain connected to gears, and the chain is connected to the hammer box.

[0007] This utility model has the following beneficial effects: This utility model provides a shell-breaking device for hot steel ladles in copper smelting. The chain is connected to the upper part of a hammer box via a fixed iron block at its middle position. A bottom gear connects to the power input end, with power provided by an electric motor, a gearbox, and a clutch. A PLC controller controls the lifting height of the hammer box and the clutch, allowing power to be transmitted through the chain to lift the hammer box to a certain height. Then, the clutch is released, and the hammer box strikes the shell-forming area of ​​the ladle below, achieving the shell-breaking effect. A trolley, powered by another electric motor, moves the entire mechanism parallel to the shell-breaking position via pulleys and guide rails after the shell-breaking operation. Finally, once the copper matte is full, a metallurgical crane lifts the ladle away. This device achieves rapid and precise shell breaking of the entire ladle, solving the problem of low efficiency in shell breaking and cleaning of the top of hot steel ladles in copper smelting due to the lack of specialized equipment.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1 As shown, a shell-breaking device for hot steel ladles in copper smelting includes a body 10, a furnace door 11 on the side of the body 10, a hammer box 1 movably mounted on the bottom of the outer wall of the body 10, a hammer tip 3 at the bottom of the hammer box 1, a reduction gearbox 6 and a clutch 14 on the bottom of the inner side of the body 10, a trolley 8 on the inner wall of the body 10, and multiple guide rails 9 on the side wall of the furnace door 11, with the trolley 8 and the guide rails 9 slidably connected. The reduction gearbox 6 and the trolley 8 are both connected to a PLC controller 13.

[0012] The hammer box 1 is equipped with a counterweight block 12, and the bottom of the hammer box 1 is surrounded by a splash guard 2, which covers the hammer tip 3.

[0013] A chain 7 is vertically installed inside the machine body 10. Both ends of the chain 7 are connected to gears 5, and the chain 7 is connected to the hammer box 1.

[0014] In practical application, after the machine body 10 is powered on, it is in the standby area. The guide rail 9 is above the furnace door 11. The first guide rail 9 is 200mm above the door, and the second guide rail 9 is 1600mm above the door. The drop hammer main unit is placed in the guide rail 9. Proximity switches and other electrical limit components are installed above the first guide rail 9. The dimensions of the machine body 10 are 00x700x1800mm. The weight of the hammer box 1 is 100KG, and the landing force is 4 tons. The dimensions of the hammer box 1 are 700x250x700mm. The lifting height of the hammer box 1 is 1800mm, the falling height of the hammer box 1 is 1800mm, the working frequency is 20 times / min, and the power is selected by a 3.0KW motor with a power of 5.0KW. The chain 7 travels between the upper and lower gears 5, with a fixed iron block connecting it to the upper structure of the hammer box 1 in the middle. The bottom gear 5 is connected to the power input. The PLC controller 13 controls the lifting height of the hammer box 1 and the clutch 14 through a preset program. Power is provided by an electric motor in conjunction with the reduction gearbox 6 and the clutch 14. The power is transmitted through the chain 7 to lift the hammer box 1 to a certain height, and then the clutch 14 is released. The hammer box 1 strikes the shelled area of ​​the ladle 4 below, achieving the shell-breaking effect. The trolley 8 is powered by another electric motor. After completing the shell-breaking operation, the entire mechanism is moved parallel to the ground via pulleys and guide rails 9, moving away from the shell-breaking position and returning to the standby area, avoiding the transport range above the copper ladle. After the copper matte is filled, the ladle 4 can be lifted away by a metallurgical crane. This completes the entire shell-breaking operation of the ladle 4, effectively reducing the impact of shell formation on the ladle 4 caused by the high-grade smelting furnace, and meeting the requirements of environmental protection, high efficiency, and low cost. Therefore, this device has good practicality.
