Description

Technical Field

[0001] This utility model relates to the technical field of oxygen-free copper rod continuous casting machines, specifically a vertical oxygen-free copper tube vacuum continuous casting equipment. Background Technology

[0002] The upward-drawing oxygen-free copper rod continuous casting unit is used to produce long, bright oxygen-free copper rods, long, bright oxygen-free copper tubes, and long, bright oxygen-free copper flat billets. The upward-drawing oxygen-free copper rod continuous casting unit can directly produce rods, tubes, flat billets, or other special-shaped profiles of different specifications from electrolytic copper through continuous melting and casting.

[0003] A search revealed that patent application number 202223350151.9 discloses an upward-drawing oxygen-free copper rod continuous casting unit, comprising a unit body, three crystallizers fixedly connected to the upper front side of the unit body, each of the three crystallizers having a copper rod body at its upper end, a connecting gas pipe fixedly connected to the rear end of the unit body, three cooling devices at the front of the connecting gas pipe, a traction roller assembly fixedly connected to the upper end of the unit body, a guide wheel frame mechanism fixedly connected to the upper end of the traction roller assembly, the three copper rod bodies extending through the traction roller assembly into the guide wheel frame mechanism, and the three cooling devices located on the outer surface of the three copper rod bodies respectively;

[0004] Although the upward-drawing oxygen-free copper rod continuous casting unit uses a cooling device on the outer surface of the copper rod, and the two air guides on the cooling device can concentrate the gas to the outer surface of the copper rod to promote cooling, the cooling effect of the upward-drawing oxygen-free copper rod continuous casting unit is poor because it cools the copper rod by blowing gas onto the surface of the copper rod.

[0005] Therefore, we propose a vertical oxygen-free copper tube vacuum continuous casting equipment. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a vertical oxygen-free copper tube vacuum continuous casting equipment, which solves the problem that existing devices, which cool the copper rod surface by blowing gas, have poor cooling effects.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a vertical oxygen-free copper tube vacuum continuous casting equipment, including a unit body, a crystallizer and a traction roller assembly, wherein three crystallizers are fixedly connected to the top surface of the unit body, an L-shaped plate is fixedly installed on the rear side of the top surface of the unit body, and a traction roller assembly is fixedly installed on the top surface of the L-shaped plate.

[0008] The L-shaped plate is provided with a cooling component for cooling the copper tubes discharged from the crystallizer.

[0009] The cooling assembly includes three hollow cooling tubes coaxially arranged with the crystallizer. Adjacent cooling tubes are connected by a connecting pipe. The connecting pipe is hollow inside and its two ends are fixedly installed at the top of the side wall of the adjacent cooling tube. The connecting pipe is connected to the inner cavity of the cooling tube. A water tank is fixedly installed on the back of the L-shaped plate. A water pump is fixedly installed on the right side wall of the water tank. The input end of the water pump is connected to the bottom of the inner cavity of the water tank. The output end of the water pump is fixedly connected to an inlet pipe. The end of the inlet pipe away from the water pump is fixedly installed at the bottom of the rightmost cooling tube side wall. A return pipe is fixedly connected to the bottom of the rightmost cooling tube side wall. The end of the return pipe away from the cooling tube is fixedly installed on the left side wall of the water pump.

[0010] Preferably, the top and bottom surfaces of the water tank are provided with evenly distributed through holes, and the interior of the water tank is provided with heat dissipation pipes corresponding to the number of through holes. The two ends of the heat dissipation pipes are respectively fixedly fitted onto the inner wall of the through holes on the same side. The temperature of the coolant inside the water tank is conducted to the heat dissipation pipes and then dissipated to the outside through the heat dissipation pipes.

[0011] Preferably, a U-shaped plate is fixedly installed on the top surface of the water tank, and three cooling fans are fixedly installed on the inner wall of the U-shaped plate. The cooling fans can increase the air circulation rate inside the heat dissipation pipe, thereby accelerating the heat dissipation efficiency of the heat dissipation pipe and thus rapidly cooling the coolant inside the water tank.

[0012] Preferably, both the heat dissipation pipe and the cooling pipe are made of copper, which has excellent thermal conductivity to facilitate heat exchange.

[0013] Preferably, a fixing plate is fixedly installed on the front side wall of the unit body, and three fixing rods corresponding to the positions of the cooling pipes are fixedly installed on the front side wall of the fixing plate. The end of the fixing rod away from the fixing plate is fixedly installed on the side wall of the cooling pipe. The fixing plate and fixing rods are used to support the cooling pipe.

[0014] This utility model provides a vertical oxygen-free copper tube vacuum continuous casting equipment. It has the following beneficial effects:

[0015] 1. This vertical oxygen-free copper tube vacuum continuous casting equipment uses a water pump to deliver coolant from the water tank to the inlet pipe. The coolant then enters the cooling tubes. Through the connection pipes, all three cooling tubes are filled with coolant, which cools the copper tubes and allows for heat exchange between the copper tubes and the coolant. This cooling effect is improved, solving the problem of poor cooling effect in existing devices that use gas to cool the copper tube surface.

[0016] 2. This vertical oxygen-free copper tube vacuum continuous casting equipment transports the cooled liquid after heat exchange back to the inside of the water tank through the return pipe. The temperature of the cooled liquid inside the water tank is conducted to the heat dissipation pipe. The cooling fan increases the air circulation rate inside the heat dissipation pipe to keep the cooled liquid at a low temperature and allows the cooled liquid to be recycled.

The bottom of the side wall of the rightmost cooling pipe 41 is fixedly connected to the return pipe 46. The end of the return pipe 46 away from the cooling pipe 41 is fixedly installed on the left side wall of the water pump 44. The water pump 44 delivers the coolant inside the water tank 45 to the inlet pipe 43. Then the coolant in the inlet pipe 43 enters the interior of the cooling pipe 41. Through the setting of the connecting pipe 42, all three cooling pipes 41 are filled with coolant, which cools the copper pipe and allows the copper pipe to exchange heat with the coolant. The cooling effect of the copper pipe is improved by the cooling effect of the coolant.

[0025] Example 2:

[0026] like Figure 1-4 As shown: The top and bottom surfaces of the water tank 45 are provided with evenly distributed through holes 451. The interior of the water tank 45 is provided with heat dissipation pipes 49 corresponding to the number of through holes 451. The two ends of the heat dissipation pipes 49 are respectively fixedly fitted onto the inner wall of the through holes 451 on the same side.

During the traction process, the water pump 44 is started to transport the coolant inside the water tank 45 to the inlet pipe 43. The coolant in the inlet pipe 43 then enters the interior of the cooling pipes 41. Through the setting of the connecting pipe 42, all three cooling pipes 41 are filled with coolant, which cools the copper tubes and allows the copper tubes to exchange heat with the coolant. Then, the coolant after heat exchange is transported back to the interior of the water tank 45 through the return pipe 46. The temperature of the coolant inside the water tank 45 is conducted to the heat dissipation pipe 49, and then the cooling fan 411 is started to increase the air circulation rate inside the heat dissipation pipe 49. The coolant then exchanges heat with the outside air through the heat dissipation pipe 49, keeping the coolant at a low temperature.
