Description

Technical Field

[0001] This utility model relates to the field of copper wire annealing technology, and in particular to an oil cooling system for copper wire annealing. Background Technology

[0002] In the production of copper wire for cables, the copper wire typically needs to be drawn first, pulled to the required diameter using a die. During the drawing process, the diameter of the copper wire gradually decreases as it is squeezed by the die. This deformation generates internal stress within the copper wire. Therefore, an annealing process is performed immediately after drawing to eliminate this internal stress. However, currently, the coolant supplied after annealing the copper wire from the drawing machine is mainly passed into a cooling tank for natural cooling or water cooling before being pumped back to the drawing machine. In mass production, the cooling efficiency and effect cannot keep up with the production speed, failing to meet the requirements of copper wire annealing.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0021] This utility model discloses an oil cooling system for copper wire annealing, comprising a storage tank 1, a cooling tank 2, a water-cooled unit, and a chiller unit.

The storage tank 1 and the cooling tank 2 are respectively located in an outdoor environment, allowing outdoor air to exchange heat with the oil. Furthermore, the inlet of the storage tank 1 is connected to the oil tank on the wire drawing machine for copper wire annealing, and the outlet of the cooling tank 2 is connected to the oil tank on the wire drawing machine for copper wire annealing. The oil in the cooling pool 2 is cooled by the heat exchanger 3, and the heat exchanger 3, the cooling tower 4 and the cooling water pool 5 form a water-cooled circuit to continuously supply coolant to the heat exchanger 3. If mass production is required, the chiller unit can be turned on for auxiliary cooling. The oil in the storage pool 1 enters the cooling pool 2 after being cooled by the chiller unit. With multiple cooling methods, the oil cooling system disclosed in this application improves the cooling efficiency and cooling effect of the oil, ensuring the normal progress of copper wire annealing and the quality of the copper wire.

[0022] The chiller unit includes a compressor, an evaporator, a condenser, and an expansion valve. The evaporator is provided with a liquid inlet, an air outlet, a water inlet, and a water outlet.

[0023] The oil cooling system also includes a water purification device 6, which includes a water pump 61, a water storage tank 62, a filter 63, and a water purifier 64. The water pump 61 connects the cooling water pool 5 and the inlet of the water storage tank 62. The filter 63 is located inside the water storage tank 62 on the side near the inlet. The water purifier 64 connects the outlet of the water storage tank 62 and the inlet of the heat exchanger 3. The water pump 61 pumps water from the cooling water pool 5 into the water storage tank 62. The water entering the water storage tank 62 passes through the filter 63 and the water purifier 64 in sequence to remove scale, impurities, and heavy metals from the water, preventing them from depositing in the heat exchanger 3 and the cooling tower 4 and affecting the heat exchange effect.

[0024] The water storage tank 62 has multiple snap-fit ​​seats 65 on its inner upper circumference. The filtration device 63 includes a sleeve 631, two filter screens 632, and a filter layer 633.

The tourmaline ceramic layer can generate negative ions. The water is instantly negatively ionized, and the rich minerals and trace elements activate the water, filtering out rust, red worms, algae, and various suspended solids. The nano-metal cluster particle layer effectively removes residual chlorine from tap water and efficiently removes heavy metal ions such as lead, cadmium, chromium, and arsenic. It effectively reduces the concentration of organic micro-pollutants and ions such as mercury and fluoride in the water. During use, it can effectively inhibit and kill bacteria, turning hard water into soft water and preventing heavy metals from accumulating and forming scale in the water pipes of the heat exchanger 3 or the cooling tower 4, thus avoiding affecting the heat exchange effect.

[0026] The cooling tower 4 includes a tower body, a heat exchange coil, a fan, two spray heads, an air inlet, and an air outlet. The air inlet and the air outlet are located opposite each other on both sides of the tower body. The heat exchange coil is located on the side of the tower body closer to the air outlet. The fan is located on the side of the tower body closer to the air inlet. The two spray heads are located on the upper and lower sides of the middle part of the tower body, respectively, and are inclined towards one side of the heat exchange coil. The heat exchange coil is connected to the heat exchanger 3 and the cooling water pool 5. The two spray heads spray water mist outwards, and the fan drives air circulation. That is, the humid air passes through the heat exchange coil for heat exchange, thereby cooling the water in the heat exchange coil and improving the heat exchange effect.
