Abstract
Description
Technical Field
[0001] The utility model relates to the field of cable machinery, in particular to a high-voltage cable circulating cooling trough. Background Art
[0002] During the extrusion production process, cold water is required to cool the extruded insulation or sheath of the cable to make it solidify and shape as quickly as possible to avoid extrusion and deformation during traction.
[0003] To conserve water, cable companies now use circulating water tanks for cooling water during extrusion. These tanks utilize natural cooling or the addition of cooling towers. Extruder discharge temperatures can reach as high as 170-190°C. During the summer heat, circulating water cooling is less effective. The water temperature in the cooling tank can reach as high as 50°C, resulting in poor cooling during extrusion. This often leads to cable flattening and damage. Furthermore, circulating water tanks are typically large, making them less suitable for cable production. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a high-voltage cable circulation cooling trough with a smaller footprint, good cooling effect and the ability to protect cables in a high-temperature state.
[0005] In order to solve the above technical problems, the utility model includes a trough body, which includes a belt conveyor device. A downward groove is formed at the upper position of the belt, and coolant is injected into the groove. The cable is arranged on the upper side of the belt and supported by two belt rollers. Part of the cable is immersed in the coolant, and the coolant is circulated through a refrigerator.
[0006] Preferably, the belt conveyor device includes two belt rollers located on both sides of the tank body, and the belt is wound around the two belt rollers. The belt rollers are shaped with a small diameter in the middle and large diameters at both ends, and the belt is loose.
[0007] In order to better maintain the groove, the outlet pipe and return pipe of the refrigerator are both extended into the groove, and rollers are installed on one side of the ends of the outlet pipe and return pipe extending into the groove, and the rollers are in contact with the top surface of the belt near the middle position.
[0008] Furthermore, the shaft of the roller is installed on a side close to the lower end of the outlet pipe and the return pipe through a shaft seat.
[0009] In order to better maintain the groove, several magnets are evenly spaced in an annular shape around the middle of the belt roller, and a steel wire rope is inserted through the middle of the belt.
[0010] In order to prevent the cable from rubbing against the upper sides of the two ends of the trough body, support rollers are installed near the upper ends of both ends of the trough body, and the cable is located on the upper side of the support rollers.
[0011] In order to ensure that the refrigerating machine does not enter impurities, the water outlet pipe and the return pipe port of the refrigerating machine are both installed with filters.
[0012] In summary, when the cable is used, a part of the cable is located in the groove, and is bent downward due to its own weight, and the bent part is immersed in the cooling liquid, and the belt can be driven to rotate as the cable advances, the belt can provide a surface support for the cable, and the cable is not easy to deform under high temperature, and the circulation of the cooling liquid in the groove is improved, and the cooling effect of the cable is improved. BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 2 It is Figure 1 A enlarged structural schematic diagram. DETAILED DESCRIPTION
[0016] Referring to the drawings Figure 1 And 2 The high-voltage cable circulating cooling tank comprises a tank body 1, a belt conveying device is arranged in the tank body 1, the belt conveying device comprises two belt rollers 2 arranged on the two sides in the tank body, a belt 3 is arranged on the two belt rollers, the belt roller 2 has a shape that the middle diameter is smaller and the two end diameters are larger, the belt is slack, and the design can form a downward groove at the upper position of the belt, cooling liquid 4 is injected into the groove, and a cable 5 is arranged on the upper side of the belt and supported by the two belt rollers, and a part of the cable is immersed in the cooling liquid for cooling.
[0017] The cooling liquid is circulated by a refrigerating machine, the water outlet pipe 6 and the return pipe 7 of the refrigerating machine are both inserted into the groove, the end portion of the water outlet pipe and the return pipe inserted into the groove is provided with a roller 8, the roller is in contact with the top surface of the belt close to the middle position, and the design can ensure that the cooling liquid in the groove keeps low temperature, and also ensure that the groove shape is stable during the advancement of the cable, so that the cooling liquid is prevented from spilling.
[0018] A plurality of magnets 11 are arranged in the middle part of the outer periphery of the belt roller, and a steel wire rope 9 is inserted in the middle of the belt, the steel wire rope can increase the tensile strength of the belt, and the middle position of the belt and the belt roller are better combined by the attraction of the magnets, so that the stability of the groove shape is further ensured.
[0019] Support rollers 10 are installed near the upper ends of both ends of the trough body 1, and the cables are located on the upper sides of the support rollers to ensure that the cables will not rub against the upper sides of both ends of the trough body, thereby improving the stability of the cable support.
