Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and more specifically, to a multi-stage cooling mechanism for copper strip processing. Background Technology

[0002] When rolling copper strip, a crystallizer is often used to hot roll the molten copper material to form copper strip. However, the temperature at which the copper strip is produced is too high, so a cooling process is required before it can proceed to the next step.

[0003] Currently, commonly used copper strip cooling devices have poor cooling effect when cooling copper strips, and coolant will flow out of the device through the copper strip surface from the inlet and outlet, causing inconvenience to users. For example, CN117884479A discloses an energy-saving multi-stage cooling device for copper strip processing, which includes a housing, and a first rotating roller evenly distributed inside the housing.

[0004] As can be seen from the above-disclosed scheme, the multi-stage cooling of the cooling device uses the same cooling method, resulting in poor cooling effect. Moreover, during the cooling process, since the height of the copper strip inside the device is higher than the height of the copper strip at both ends of the device's inlet and outlet, the coolant will flow along the surface of the copper strip to both ends, causing the coolant to leak out and requiring frequent cleaning by staff, which brings great inconvenience to users. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a multi-stage cooling mechanism for copper strip processing. This multi-stage cooling mechanism for copper strip processing, through the setting of a first cooling chamber, a second cooling chamber, and a third cooling chamber, can gradually cool the copper strip through different cooling methods, greatly improving the cooling effect. Furthermore, through the setting of a drying mechanism, not only can the surface of the copper strip be cooled, but residual coolant on the surface can also be removed, preventing coolant from flowing out through the inlet and outlet of the copper strip, thus improving the convenience of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A multi-stage cooling mechanism for copper strip processing includes a cooling mechanism body with an inlet and an outlet at both ends. Guide rollers are rotatably connected to the inner walls of both the inlet and outlet, and copper strips are movably connected to the surfaces of the guide rollers. Two baffles are fixedly connected to the inner wall of the cooling mechanism body, dividing the interior of the cooling mechanism body into a first cooling chamber, a second cooling chamber, and a third cooling chamber. A spray mechanism is fixedly installed on the inner wall of the first cooling chamber, a limit roller is rotatably connected to the inner wall of the second cooling chamber, and a drying mechanism is fixedly installed on the inner wall of the third cooling chamber. This multi-stage cooling mechanism for copper strip processing, through the first, second, and third cooling chambers, allows for gradual cooling of the copper strip using different cooling methods, greatly improving the cooling effect. Furthermore, the drying mechanism not only cools the surface of the copper strip but also removes residual coolant, preventing coolant from flowing out through the inlet and outlet of the copper strip, thus improving ease of use.

[0008] Furthermore, the spraying mechanism includes a spray box with a first through hole on its surface. An upper spray head and a lower spray head are fixedly installed on the inner wall of the first through hole. One end of the upper spray head is fixedly connected to a first conveying pipe, and one end of the lower spray head is fixedly connected to a connecting pipe. Both the upper and lower spray heads are atomizing spray heads, which can cool the copper strip by atomizing and spraying coolant.

[0009] Furthermore, the drying mechanism includes a drying box, the inner wall of which is fixedly connected to a partition, the partition and the inner wall of the drying box enclosing a fabric chamber, the inner wall of which is fixedly connected to a short pipe, one end of which is fixedly connected to a second conveying pipe, and one end of which is connected to a nitrogen conveying pipe, which can convey nitrogen into the fabric chamber.

[0010] Furthermore, a second through hole is opened in the middle of the partition plate, and a spray hole is opened on the inner wall of the second through hole. One end of the spray hole is connected to the cloth chamber, and the spray hole can blow nitrogen gas in the cloth chamber evenly onto the upper and lower surfaces of the copper strip for cooling.

[0011] Furthermore, the surface of the baffle has a rectangular hole, and a protective roller is rotatably connected to the inner wall of the rectangular hole. Limiting rings are fixedly connected to both ends of the protective roller. The protective roller can prevent the copper strip from contacting the baffle, while the limiting rings can restrict the copper strip from moving to both sides.

[0012] Furthermore, one end of the connecting pipe is fixedly connected to the surface of the first conveying pipe, the surface of the first conveying pipe is fixedly connected to the surface of the cooling mechanism body, and one end of the first conveying pipe is connected to a circulation pump, which can circulate the coolant.

[0013] Furthermore, the second cooling chamber contains coolant, the level of which is higher than the height of the limiting roller, facilitating the immersion of the copper strip in the coolant for cooling.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This scheme, by setting up a first cooling chamber, a second cooling chamber and a third cooling chamber, can gradually cool the copper strip through different cooling methods, which greatly improves the cooling effect.

[0016] (2) The drying mechanism in this solution can not only cool the surface of the copper strip, but also remove the residual coolant on the surface, thus preventing the coolant from flowing out through the inlet and outlet of the copper strip and improving the ease of use.

[0025] Example 1

[0026] Please see Figure 1-5 A multi-stage cooling mechanism for copper strip processing includes a cooling mechanism body 1. The cooling mechanism body 1 has an inlet 11 and an outlet 12 at both ends. Guide rollers 13 are rotatably connected to the inner walls of both the inlet 11 and outlet 12. A copper strip 2 is movably connected to the surface of the guide rollers 13. Feeding and receiving mechanisms are provided at both ends of the copper strip 2 to facilitate cooling of the copper strip 2 through the cooling device. Two baffles 5 are fixedly connected to the inner wall of the cooling mechanism body 1, dividing the interior of the cooling mechanism body 1 into a first cooling chamber 14, a second cooling chamber 15, and a third cooling chamber 16. Each of the first, second, and third cooling chambers 14 and 16 is equipped with a feeding nozzle and a discharging nozzle, which is prior art. The second cooling chamber 15 is connected to a refrigeration mechanism and a turbulence assembly, which can cool and turbulently flow the internal coolant to increase the cooling effect. A spray mechanism 3 is fixedly installed on the inner wall of the first cooling chamber 14. The spray mechanism 3 includes a spray box 31, and a first through hole 32 is opened on the surface of the spray box 31. An upper nozzle 35 and a lower nozzle 36 are fixedly installed on the inner wall. One end of the upper nozzle 35 is fixedly connected to a first conveying pipe 33, and one end of the lower nozzle 36 is fixedly connected to a connecting pipe 34. Both the upper nozzle 35 and the lower nozzle 36 are atomizing nozzles, which can cool the copper strip 2 by atomizing and spraying coolant. A limit roller 17 is rotatably connected to the inner wall of the second cooling chamber 15. A drying mechanism 4 is fixedly installed on the inner wall of the third cooling chamber 16. The drying mechanism 4 includes a drying box 41, and the inner wall of the drying box 41 is fixedly connected to a limit roller 17. A partition 44 is connected, and the partition 44 and the inner wall of the drying box 41 enclose a cloth-feeding chamber 45. A short pipe 43 is fixedly connected to the inner wall of the cloth-feeding chamber 45. One end of the short pipe 43 is fixedly connected to a second conveying pipe 42. One end of the second conveying pipe 42 is connected to a nitrogen conveying pipe, which can deliver nitrogen into the cloth-feeding chamber 45. The drying mechanism 4 cools the surface of the copper strip 2 with nitrogen. The surface of the copper strip 2 is blown with nitrogen to remove residual moisture. At the same time, the low temperature characteristics of nitrogen are used for cooling to prevent the copper strip 2 from oxidizing.

[0027] A second through hole 47 is opened in the middle of the partition 44. A spray hole 46 is opened on the inner wall of the second through hole 47. One end of the spray hole 46 is connected to the cloth chamber 45. The spray hole 46 can blow nitrogen gas in the cloth chamber 45 evenly onto the upper and lower surfaces of the copper strip 2 for cooling. A rectangular hole 51 is opened on the surface of the baffle 5. A protective roller 52 is rotatably connected to the inner wall of the rectangular hole 51. Limiting rings 53 are fixedly connected to both ends of the protective roller 52. The protective roller 52 can prevent the copper strip 2 from contacting the baffle 5. At the same time, the limiting rings 53 can restrict the copper strip 2 from moving to both sides.

[0028] One end of the connecting pipe 34 is fixedly connected to the surface of the first conveying pipe 33, and the surface of the first conveying pipe 33 is fixedly connected to the surface of the cooling mechanism body 1. One end of the first conveying pipe 33 is connected to a circulation pump, which can circulate the coolant. The second cooling chamber 15 stores coolant, and the level of the coolant is higher than the height of the limiting roller 17, so that the copper strip 2 can be immersed in the coolant for cooling.

[0029] In operation, the multi-stage cooling mechanism for copper strip processing involves the copper strip 2 entering the first cooling chamber 14 through inlet 11. As the copper strip 2 passes through the first through-hole 32, atomized coolant sprayed from the upper nozzle 35 and lower nozzle 36 provides initial cooling to the surface of the copper strip 2. After initial cooling, the copper strip 2 moves to the right into the second cooling chamber 15, where it is immersed in the coolant stored for further cooling. After completing the second cooling, the copper strip 2 moves to the right, exiting the coolant surface and entering the third cooling chamber 16. When the copper strip 2 enters the second through-hole 47 to the right, nitrogen gas is supplied to the cloth-feeding chamber 45 via the second conveying pipe 42. The nitrogen gas passes through the second... The spray holes 46 on the upper and lower inner walls of the through hole 47 blow and cool the upper and lower surfaces of the copper strip 2, while drying the residual liquid. After cooling and drying, the copper strip 2 moves to the right through the outlet 12 out of the cooling mechanism body 1. Through the first cooling chamber 14, the second cooling chamber 15 and the third cooling chamber 16, the copper strip 2 can be cooled step by step through different cooling methods, which greatly improves the cooling effect. In addition, the drying mechanism 4 can not only cool the surface of the copper strip 2, but also remove the residual coolant on the surface, preventing the coolant from flowing out through the inlet and outlet of the copper strip 2, thus improving the convenience of use.
