Description

Technical Field

[0001] This invention relates to the field of copper rod production technology, specifically to a copper rod production process and its crystallizer. Background Technology

[0002] Copper rods are a raw material used in the production of wires and cables.

[0003] According to patent application number CN202023050016.3, a molded sleeve is provided at the bottom of the main pipe, an inner sleeve is fitted on the outside of the main pipe, and an outer sleeve is fitted on the outside of the inner sleeve. A cooling chamber is enclosed between the inner sleeve and the main pipe, and a water inlet chamber is enclosed between the inner sleeve and the outer sleeve. A notch is provided at the bottom of the inner sleeve for connecting the water inlet chamber and the cooling chamber. An air extraction pipe is provided on the upper side of the main pipe, which is connected to the inside of the main pipe. The air extraction pipe passes through the inner sleeve and the outer sleeve and extends to the outside of the outer sleeve. The inner sleeve has a water outlet pipe on its upper side, which passes through the outer sleeve and extends to the inside of the outer sleeve. The water outlet pipe is connected to the cooling chamber. The outer sleeve has multiple water inlet pipes, which are connected to the water inlet chamber. The upper and middle parts of the inner sleeve have multiple through holes. By extracting the internal air, oxidation of the copper rod surface is avoided. The multiple water inlet pipes increase the amount of cooling water entering the cooling chamber. The through holes replenish the cooling water to the upper and middle parts of the cooling chamber, improving the cooling effect on the upper and middle parts of the main pipe, reducing problems such as loose copper rod structure, cold shuts, and cracks, and improving the quality of the copper rod.

[0004] In the aforementioned patent, cooling water is introduced between the main pipe and the inner sleeve to achieve a cooling effect. However, under long-term use, due to the high hardness of the water, dirt easily accumulates between the outer and inner pipes, adhering to the pipe walls and increasing the wall thickness, which affects the cooling effect of the copper rod. Impurities in the water can also easily cause wear on the pipe walls. Existing technology requires disassembling the inner and outer pipes and then using a cleaning device to clean the dirt on the pipe walls. This method is time-consuming and labor-intensive, and it is difficult to achieve automatic cleaning of the pipe walls inside the crystallizer, which increases the labor intensity. Therefore, in view of the above shortcomings, the present invention makes the following improvements. Summary of the Invention

[0040] In this embodiment of the invention, the limiting component 8 includes a ball block 81 fixedly disposed at the top of the vertical rod 74, a buffer spring 82 fixedly connected to the top of the upper section tube 3, and an annular plate 83 fixedly connected to the top of the buffer spring 82.

[0041] In this embodiment of the invention, the bottom of the annular plate 83 is fixedly connected to an extrusion rod 84 that penetrates into the interior of the upper section tube 3, and a semi-circular block adapted to the ball block 81 is fixedly disposed on the surface of the extrusion rod 84 inside the upper section tube 3.

[0042] In this embodiment of the invention, a support rod is fixedly connected to the top end of the upper section pipe 3. There are two support rods arranged symmetrically on the left and right. A baffle 85 is rotatably connected to the surface of the support rod. The top and bottom ends of the inner pipe 2 are fixedly connected to the surfaces of the upper section pipe 3 and the lower section pipe 4, respectively. A graphite sleeve 9 is fixedly installed at the bottom end of the inner pipe 2.

[0043] In this embodiment of the invention, a discharge trough is provided at the bottom of the lower section pipe 4, and a solenoid valve 10 is fixedly connected inside the discharge trough. A water circulation mechanism 11 is provided on the surface of the water tank 1, and a cooler is provided inside the water tank 1. The cooler is an existing device and will not be described in detail in this application. The water circulation mechanism 11 includes a pressure pump 111 and a water inlet pipe 112 connected to the bottom of one side of the water tank 1. A first one-way valve is fixedly provided inside the water inlet pipe 112. The first one-way valve can prevent water from flowing back into the water tank 1. One end of the water inlet pipe 112 is connected to one side of the surface of the upper section pipe 3.

[0044] In this embodiment of the invention, a drain pipe 113 is connected to one side of the surface of the lower section pipe 4, and one end of the drain pipe 113 is connected to the inlet of the pressure pump 111. The outlet of the pressure pump 111 is connected to a heat dissipation pipe 114.

[0045] In this embodiment of the invention, the top end of the heat dissipation pipe 114 is connected to the bottom of the water tank 1 through the vertical pipe 115. A second one-way valve is fixedly connected inside the vertical pipe 115. The setting of the second one-way valve can prevent water from flowing back into the heat dissipation pipe 114.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] In use, the bottom end of the inner tube 2 is connected to the heat preservation furnace through the graphite sleeve 9. The cooler inside the water tank 1 is turned on in advance to cool the water inside the water tank 1. The cooled water is then transported through the inlet pipe 112 to the cavity formed between the outer tube and the inner tube 2. The copper liquid flows upward from the bottom end of the inner tube 2. The cooling water inside the cavity absorbs the heat of the copper liquid in the inner tube 2, causing the copper liquid to gradually solidify. During the cooling process, the pressure pump 111 is started, which transports the water that has absorbed enough heat inside the outer tube to the heat dissipation pipe 114 through the drain pipe 113. The heat is dissipated in advance through the heat dissipation pipe 114. Then, the water is transported back to the water tank 1 through the vertical pipe 115 under pressure. The water is cooled again by the cooler inside the water tank 1, thus forming a circulation loop to save water resources. A separate traction mechanism is set above the inner tube 2 to continuously pull out and transport the copper rod after the copper liquid has been cooled and solidified.

[0048] After the copper rod forming process is completed, the baffle 85 is rotated along the vertical rod 74 until it disengages from the limiting fixation of the annular plate 83. Once the annular plate 83 is released from its limiting position, the buffer spring 82 generates an upward reaction force, causing the annular plate 83 to move the extrusion rod 84 upward. This releases the semicircular block on the extrusion rod 84 from its limiting position on the ball block 81. At this point, the vertical rod 74 moves closer to the surface of the inner tube 2 under the force of the spring rod 73 until the cleaning brush 75 on the vertical rod 74 contacts the surface of the inner tube 2, thus initiating the process. Motor 71 drives gear 76 to rotate, which in turn drives rotating ring 77 to rotate through its teeth. Consequently, annular block 5 rotates synchronously. During the rotation of annular block 5, cleaning brush 75 on its surface can be driven to rotate through T-shaped rod 72. Subsequently, vertical rod 74 and cleaning brush 75 on its surface rotate synchronously. During the rotation, the surface of inner tube 2 and the inner wall of outer tube come into contact, thereby cleaning the tube wall. Finally, the cleaned impurities are discharged through discharge chute. All structures inside the outer tube are treated with anti-rust treatment.
