[0002] Polyethylene is a thermoplastic resin obtained through the polymerization reaction of ethylene monomers, referred to as PE material. It has excellent low-temperature resistance, good chemical stability, is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation.
[0003] As a thermoplastic resin, polyethylene needs to be processed at high temperature. This makes the produced polyethylene often have a high temperature. The produced polyethylene resin needs to be cooled. The existing cooling equipment generally cools by water cooling. Since the density of polyethylene resin is smaller than that of water, it will float on the surface of cooling water. In this way, polyethylene gathers on the surface of cooling water during cooling, making the water temperature on the surface of cooling water higher, and the cooling effect on polyethylene is poor, and the polyethylene cannot be fully cooled.
[0004] Based on this, the present invention designs a multi-stage cooling device and cooling method for polyethylene resin material for power cables to solve the problem that the polyethylene resin floats on the surface of cooling water, resulting in poor cooling effect. Summary of the invention

[0017] See also Figure 1-7The present invention provides a technical solution: a multi-stage cooling device for polyethylene resin material for power cable, comprising a cooling water tank 1, one end of the cooling water tank 1 is fixedly connected to a feeding barrel 4, the rear end of the cooling water tank 1 is fixedly connected to a feeding plate 5, a conveying frame 8 is arranged on the rear side of the feeding plate 5, a wind cooling frame 7 is fixedly connected to the top of the conveying frame 8, both sides of the cooling water tank 1 are rotatably connected to a connecting frame 2, a fixed shaft 10 is fixedly connected to the cooling water tank 1, a fixed frame 12 is rotatably connected to the connecting frame 2, a horizontal flip assembly is arranged on the fixed frame 12, and the horizontal flip assembly is used to keep the fixed frame 12 in a horizontal position when the connecting frame 2 rotates, and rotate with the connecting frame 2; When the above scheme is put into practical use, the produced polyethylene resin material is transported to the inside of the cooling water tank 1 through the feeding tube 4, and the fixed frame 12 is driven to rotate by the connecting frame 2, so that the polyethylene resin floating on the liquid surface inside the cooling water tank 1 is pressed into the cooling water tank 1 for cooling. During the process, the connecting frame 2 drives the fixed frame 12 to rotate through the horizontal flip assembly, so that the fixed frame 12 can always maintain a horizontal downward position while rotating with the connecting frame 2, pressing the polyethylene resin to slide inside the cooling water tank 1. After cooling, the polyethylene resin will be transported to the inside of the conveying frame 8 through the feeding plate 5. While being transported inside the conveying frame 8, the polyethylene is further cooled by the air cooling frame 7 to air-dry the surface moisture. The advantage of this is that the polyethylene resin is pressed to slide inside the cooling water tank 1 by the fixed frame 12, and the horizontal flip group drives the fixed frame 12 to rotate horizontally downward inside the cooling water tank 1, so that the polyethylene resin at the bottom of the fixed frame 12 can fully contact with the cooling water inside the cooling water tank 1 for cooling, thereby improving the cooling effect on the polyethylene resin.
[0018] As a further solution of the present invention, the horizontal flip assembly includes a fixed gear 15, the fixed gear 15 is fixedly arranged at one end of the fixed shaft 10, the connecting frame 2 is rotatably connected to a second gear 14 meshing with the fixed gear 15, the connecting frame 2 is rotatably connected to a first gear 9 meshing with the second gear 14, the first gear 9 is fixedly connected to the center of the front end outer wall of the fixed frame 12, the top rear side of the fixed frame 12 is rotatably connected to a folding plate 6, the front end of the folding plate 6 is fixedly connected to a telescopic rod 16, the upper end of the cooling water tank 1 is fixedly connected to a limiting rod 3, and one side of the limiting rod 3 is provided with a slide groove 19 for docking with the telescopic rod 16; When the above scheme is put into practical use, after the polyethylene resin enters the cooling water tank 1 through the feeding tube 4, as shown in the cooling water tank 1 and the limit rod 3 in the figure, the connecting frame 2 drives the fixed frame 12 to rotate together in the cooling water tank 1 along the counterclockwise direction as shown in the limit rod 3 in the figure. Since the fixed gear 15 and the fixed shaft 10 are fixed inside the cooling water tank 1, when the connecting frame 2 rotates, the second gear 14 will rotate around the fixed gear 15, and the rotation of the second gear 14 will drive the first gear 9 to rotate together, and the first gear 9 will drive the fixed frame 12 to flip, so that the connecting frame 2 When the rotation is continued, the fixed frame 12 is continuously flipped, and the compensation amount of the flipping of the fixed frame 12 makes the flipping angle of the fixed frame 12 driven by the connecting frame 2 to be zero, that is, the fixed frame 12 is always in a horizontal position compared to the horizontal plane. The purpose of this is that after the fixed frame 12 covers the polyethylene resin from the upper end of the polyethylene resin, the polyethylene resin can be transported in the cooling water tank 1 in a horizontal position. Because the density of the polyethylene resin is less than that of water, once the fixed frame 12 is deflected, the polyethylene resin material will be piled up under the action of buoyancy, affecting the cooling effect; When the fixed frame 12 rotates to the top of the cooling water tank 1 again, that is, the fixed frame 12 has been separated from the liquid surface inside the cooling water tank 1, the polyethylene resin will remain on the liquid surface, and the connecting frame 2 continues to rotate so that the bottom fixed frame 12 rotates upward and gradually contacts the polyethylene resin through the top folding plate 6. When the fixed frame 12 rotates to the position where the telescopic rod 16 contacts the slide groove 19, the fixed frame 12 continues to rotate and the telescopic rod 16 slides along the slide groove 19, so that the top folding plate 6 will flip around the rear side of the fixed frame 12 at a certain angle, pushing the polyethylene resin on the surface of the folding plate 6 into the feeding plate 5, and then transported to the inside of the conveying rack 8 through the feeding plate 5. After being air-cooled and dried by the conveying rack 8, the cooling is completed.
[0019] As a further solution of the present invention, the tops of the fixing frames 12 on both sides of the folding plate 6 are respectively fixedly connected with baffles 11; When the above solution is put into actual use, the polyethylene resin is limited by the baffle 11 so that it can be fully located above the folding plate 6 and then transported through the folding plate 6.
[0020] As a further solution of the present invention, the folding plate 6 and the fixed frame 12 are respectively provided with a plurality of equally spaced drainage openings 17, and the bottom of the fixed frame 12 is fixedly connected with a plurality of equally spaced separation rods 18; When the above scheme is put into actual use, the drain port 17 is used to allow the cooling water inside the cooling water tank 1 to better pass through the fixed frame 12 when the fixed frame 12 rotates inside the cooling water tank 1, and fully contact with the polyethylene resin for cooling, while the separation rod 18 is used to limit the polyethylene resin so that the polyethylene resin can be evenly distributed inside the fixed frame 12, avoiding the water flow from causing the polyethylene resin to move and accumulate.
[0021] As a further solution of the present invention, the vertical plane where the telescopic rod 16 is located does not intersect with the vertical plane where the second gear 14 is located; When the above solution is put into actual use, since the fixed frame 12 is always horizontal, the second gear 14 rotates compared to the telescopic rod 16. The second gear 14 and the telescopic rod 16 are not located in the same vertical plane so that the telescopic rod 16 will not hinder the rotation of the second gear 14.
[0022] As a further solution of the present invention, the outer wall of the feeding plate 5 is a smooth wall, and a vibration motor is fixedly connected to the bottom of the feeding plate 5; When the above solution is put into practical use, the polyethylene is further transported by the vibration motor to prevent it from being blocked on the feeding plate 5.
[0023] As a further solution of the present invention, one end of the cooling water tank 1 is fixedly connected to a first motor, the output shaft of the first motor passes through the cooling water tank 1 and is fixedly connected to the connecting frame 2, and one end of the conveying frame 8 is fixedly connected to a second motor; When the above solution is put into actual use, the first motor drives the connecting frame 2 to rotate, and the polyethylene resin material is transported to the interior of the cooling water tank 1 for sufficient cooling treatment.
[0024] A multi-stage cooling method for polyethylene resin material for power cable, applicable to any multi-stage cooling device for polyethylene resin material for power cable according to claims 1-7, characterized in that the method comprises the following steps: Step 1: discharge the produced polyethylene resin into the cooling water tank 1 through the feeding cylinder 4; Step 2: Flip the assembly horizontally so that the fixing frame 12 pushes the polyethylene resin to be fully cooled inside the cooling water tank 1; Step 3: The cooled vinyl resin is transported to the conveying rack 8 via the feeding plate 5; Step 4: Finally, transport the product on the conveyor rack 8 and pass through the air cooling rack 7 for further cooling and drying.
[0025] Working principle: The produced polyethylene resin material is transported to the inside of the cooling water tank 1 through the feeding barrel 4, and the connecting frame 2 drives the fixed frame 12 to rotate together in the cooling water tank 1 along the counterclockwise direction as shown by the limit rod 3 in the figure. Since the fixed gear 15 and the fixed shaft 10 are fixed in the cooling water tank 1, the second gear 14 will rotate around the fixed gear 15 when the connecting frame 2 rotates, and the rotation of the second gear 14 drives the first gear 9 to rotate together, and the first gear 9 will drive the fixed frame 12 to flip. In this way, when the connecting frame 2 continues to rotate, the fixed frame 12 continues to flip, and the compensation amount of the flipping of the fixed frame 12 makes the flipping angle of the fixed frame 12 driven by the connecting frame 2 to be zero, that is, the fixed frame 12 is always in a horizontal position compared to the horizontal plane. The purpose of this is that after the fixed frame 12 covers the polyethylene resin from the upper end of the polyethylene resin, the polyethylene resin can be transported in the cooling water tank 1 in a horizontal position. Because the density of polyethylene resin is less than that of water, once the fixed frame 12 is deflected, the polyethylene resin material will pile up under the action of buoyancy, affecting the cooling effect; When the fixed frame 12 rotates to the top of the cooling water tank 1 again, that is, the fixed frame 12 has been separated from the liquid surface inside the cooling water tank 1, the polyethylene resin will remain on the liquid surface, and the connecting frame 2 continues to rotate so that the bottom fixed frame 12 rotates upward and gradually contacts the polyethylene resin through the top folding plate 6. When the fixed frame 12 rotates to the position where the telescopic rod 16 contacts the slide groove 19, the fixed frame 12 continues to rotate and the telescopic rod 16 slides along the slide groove 19, so that the top folding plate 6 will flip around the rear side of the fixed frame 12 at a certain angle, pushing the polyethylene resin on the surface of the folding plate 6 into the feeding plate 5, and then transported to the inside of the conveying rack 8 through the feeding plate 5. After being air-cooled and dried by the conveying rack 8, the cooling is completed.
