Description

Technical Field

[0001] The invention relates to the field of cable manufacturing, and in particular to a cooling and molding device for producing power cables. Background Art

[0002] The cooling and forming device for power cable production is a device that has a cooling effect during cable production. The power cable is produced by thermally forming the cable shell. Therefore, the cable needs to be quickly cooled after the cable shell is processed to form the cable. Therefore, the cooling and forming device for power cable production is the last step of cable production and is widely used in various power production occasions.

[0003] The Chinese patent with application number "CN201811426368.9" discloses "a low-voltage silane cross-linked cable cooling molding process, comprising the following steps: 1) allowing the cable to enter a first water tank for cooling, the first water tank being a heat-insulating circulating cooling water tank, the water temperature of the first water tank being 50-70°C; 2) the cable removed from the first water tank enters a static second water tank with a water temperature of 35-45°C;", although it can achieve the effect of "that is, the cooling molding process allows the cable to be cooled first under flowing hot water and then in a static water body, cooled by hot air and then by cold air, so as to reduce the internal stress of the insulating layer and the conductive layer, and obtain a low-voltage silane cross-linked cable with good weather resistance and controllable shrinkage", but when the cable is cooled, a water tank structure is used to cool the cable. The cable is placed in a water tank for continuous mobile cooling, but the water tank structure is large in size, resulting in a large footprint and is difficult to build and dismantle, making the device inconvenient to use. When the cable is placed in the water tank, the water pressure in the water tank is low, and the cable can only be cooled and shrunk by temperature. However, the cable is heated too much and expands too much during hot forming. The cable shell cannot be completely shrunk by cooling alone, which reduces the quality of cable forming. At the same time, the water tank is too large, and the water circulation speed inside it is slow, which can also cause heat accumulation, resulting in insufficient water cooling and affecting cable cooling. Finally, when the cable is discharged, air is required to blow off the water on the cable, but the cable is placed in and discharged from the water tank in parallel, and the air cannot blow and dewater the cable comprehensively, which is prone to water stains.

At the same time, the water can also enter the water tank base more quickly for circulation, preventing the heat accumulation caused by insufficient water cooling from affecting the cooling of the cable;

[0019] When the cable passes through the discharge pipe and the tapered pipe mouth for discharge, the air enters the annular nozzle through the air pipe joint and is ejected from the jet hole below to spray the water stains on the outside of the cable downwards, and the water then drips into the tapered pipe mouth. The jet holes arranged in an annular manner can fully spray water from the cable to prevent the problem of residual water stains after the cable is cooled, further facilitating the use of cable cooling and forming.

[0038] It should be noted that the present invention is a cooling and forming device for power cable production. When in use, cooling water is injected into the water tank base 1 and the cooling tank 10. The newly produced cable 41 passes through the inlet pipe 12 into the cooling tank 10 and is wound on the threaded groove 25 on the outside of the cable reel 23. The end of the cable 41 passes through the discharge pipe 30 and passes out from the upper end conical pipe 31 of the discharge pipe 30. Therefore, after the cable 41 enters the cooling tank 10, it contacts with water for cooling and forming. At the same time, the driving motor 16 The operation drives the driving gear 17 to rotate, and the driving gear 17 drives the rotating column 19 to rotate by meshing with the transmission gear 20.

[0039] After the water is cooled by the cooling box 6, it is transported to the circulating water pump 3 through the return water pipe 5. The circulating water pump 3 then transports the water to the delivery water pipe 37. The delivery water pipe 37 then transports the water to the drain pipe 39 through the rotary joint 38. Finally, the water is discharged by the multiple drainage nozzles 40 outside the drain pipe 39, so that the cooled water enters the cooling tank 10 again to cool the cable. The multiple drainage nozzles 40 are arranged in a spiral. When the water is discharged, thrust is generated to push the multiple drainage nozzles 40 and the drain pipe 39 to rotate around the rotary joint 38, so that the water in the cooling tank 10 moves in a spiral shape. The water passes through the water permeable holes 26 to the greatest extent and contacts the cable 41, thereby improving the cooling efficiency of the water contacting the cable 41. At the same time, the water can also enter the water tank base 1 more quickly for circulation.

[0040] When the cable 41 passes through the discharge pipe 30 and the tapered pipe mouth 31 for discharge, the cable 41 passes through from bottom to top, and at the same time, the cable 41 passes through the annular nozzle 33 and is connected to the air pipe by the air pipe joint 34, so that air enters the annular nozzle 33 through the air pipe joint 34 and is sprayed out from the jet hole 35 below to spray the water stains on the outside of the cable 41 downwards, and the water then drips into the tapered pipe mouth 31, thereby achieving comprehensive jet water removal for the cable 41.
