Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a cooling device for cable production, belonging to the technical field of cable production. Background Art

[0002] Cables are an indispensable infrastructure in modern power, communication and other technological fields. They are usually composed of one or more conductors (usually copper or aluminum) wrapped in insulating materials to prevent current loss or short circuits with other conductors. Cables are used to transmit power and signals, including but not limited to home and commercial power supply, telecommunications, rail transportation and industrial automation.

[0003] Cooling is one of the important processes in the cable production process. Cable insulation materials are usually covered on the conductor by extrusion or casting. During the extrusion process, the insulation material melts at high temperature and evenly covers the conductor. After the construction of the insulation layer is completed, it is necessary to solidify the insulation layer by cooling to make it a hard insulator.

[0004] Traditionally, when cooling cables, room temperature water is mostly used to directly cool the cables after extrusion. Since the temperature difference between water and cable is usually large, although cooling can be completed quickly, the mechanical strength and insulation performance of the cable insulation layer are easily affected. In addition, a large amount of water stains will remain on the surface of the cable after water cooling, which can easily pollute the production environment. Therefore, a cooling device for cable production is proposed. Utility Model Content

[0057] When the utility model is in operation, the extruded cables are placed in the hot water bin 102, the normal temperature water bin 103 and the cold water bin 104, and sequentially pass through the driving conical roller 205 and the supporting conical roller 206 to complete the cable arrangement operation.

[0058] When the cable needs to be transported, the output shaft of the driving motor 201 drives the belt driving wheel 202 to rotate, and the rotating belt driving wheel 202 drives the belt driven wheel 204 to rotate using the transmission belt 203. The rotating belt driven wheel 204 drives the driving conical roller 205 to transport the cable, and the supporting conical roller 206 is provided to support the bottom of the cable.

[0059] High-pressure air is injected into the vortex tube 303 through the variable frequency air pump 302, and then the vortex tube 303 is used to separate the high-pressure air into cold and hot air flows, and then the hot air flow is guided to the inside of the hot water tank 102 through the heat transfer conduit 304, and the water in the hot water tank 102 is heated by the heat transfer conduit 304 to reduce the temperature difference between the water in the hot water tank 102 and the cable, so as to perform a preliminary cooling treatment on the cable, and then the cable is subjected to a secondary cooling treatment using the normal temperature water in the normal temperature water tank 103, and then the cold air flow is guided into the inside of the cold water tank 104 through the cold transfer conduit 305, so as to absorb the heat of the water in the cold water tank 104 through the cold transfer conduit 305, so as to cool the water in the cold water tank 104, so as to perform a tertiary cooling treatment on the cable using the cooled water in the cold water tank 104, so that its temperature is finally reduced to a normal temperature state.

[0061] The temperature data of the water in the cold water bin 104 is detected by the set temperature sensor 501, and the data detected by the temperature sensor 501 is received by the frequency conversion controller 503. When the data detected by the temperature sensor 501 is lower than the threshold value, the frequency conversion controller 503 controls the frequency conversion air pump 302 to operate at a low frequency. When the data detected by the temperature sensor 501 is higher than the threshold value, the frequency conversion controller 503 controls the frequency conversion air pump 302 to operate at a high frequency, so as to control the temperature in the cold water bin 104.
