Description

Technical Field

[0001] This invention belongs to the field of power cable manufacturing technology, specifically a cooling process for manufacturing environmentally friendly fire-resistant aluminum alloy power cables. Background Technology

[0002] Cables refer to materials used for power, electrical, and related transmission purposes. There is no strict boundary between "wires" and "cables." Generally, products with fewer cores, smaller diameters, and simpler structures are called wires, while those without insulation are called bare wires, and others are called cables. The cable industry is a basic industry with a wide variety of products and a very wide range of applications, involving industries such as power, construction, communications, and manufacturing. It is an indispensable basic material for transmitting electrical energy, transmitting information, and manufacturing various motors, instruments, and meters to realize electromagnetic energy conversion. It is a necessary basic product for future electrification and informatization.

[0003] During the manufacturing process of environmentally friendly fire-resistant aluminum alloy power cables, cooling is required. Traditional cooling involves immersing the cable in water. However, sudden immersion in water can cause excessive stress or defects due to rapid cooling. Furthermore, the water temperature in the cooling pool gradually increases during continuous cooling, affecting the subsequent cooling effect. After cooling, the cable surface usually carries moisture. As the moisture dries slowly, water stains remain on the cable surface. If these water droplets are carried to the next process, they can also affect subsequent work.

[0004] Therefore, we propose an environmentally friendly cooling process for manufacturing fire-resistant aluminum alloy power cables to solve the problems encountered above. Summary of the Invention

[0005] The purpose of this invention is to address the challenges of cooling environmentally friendly fire-resistant aluminum alloy power cables during manufacturing. Traditional cooling methods involve immersing the cable in water, which can cause excessive stress or defects due to sudden cooling. Furthermore, the water temperature in the cooling tank gradually increases during continuous cooling, affecting subsequent cooling effects. After cooling, the cable surface often carries moisture, which can leave water stains after slow drying. If these water droplets are carried to the next process, they can also affect subsequent operations. Therefore, this invention proposes an environmentally friendly cooling process for manufacturing fire-resistant aluminum alloy power cables.

[0006] The objective of this invention can be achieved through the following technical solution: A cooling process for manufacturing environmentally friendly fire-resistant aluminum alloy power cables includes the following steps;

[0007] Step 1, Pre-cooling treatment: The cable enters the interior of the cooling box through the inlet and outlet holes at the left end of the cooling box. It first passes through the annular spray pipe of the water mist spraying mechanism, so that when the water mist spraying mechanism is working, it sprays water mist on the outer circumference of the cable, thus initially cooling the cable.

[0008] Step 2, Immersion Cooling Treatment: Next, the cable passes through the limiting guide roller on the left side of the cooling pool in sequence. Then, the pressure roller presses the middle part of the cable into the water. After that, the cable moves to the right out of the cooling pool through the limiting guide roller on the right side. When the cable passes through the inside of the cooling pool, it comes into contact with the cooling water in the cooling pool, which can conduct heat to the water and realize the cooling of the cable.

[0009] Step 3, Surface Dehydration: After cooling, the cable is then moved to the bottom of the dehydration mechanism, so that the two sets of water-absorbing sponges in the middle contact the front and back of the cable respectively. As the cable is moved to the right, the water-absorbing sponges will remove the water droplets remaining on the surface of the cable.

[0010] Step 4: Discharge: The cable, after surface dehydration, is removed from the cooling box through the inlet / outlet hole on the right side of the cooling box, allowing it to proceed with subsequent operations.

[0013] In a preferred embodiment of the present invention, pressure rollers are rotatably installed inside both the left and right sides of the cooling pool, and the lower end of the pressure rollers abuts against the upper surface of the cable. Annular mounting plates are rotatably connected to the outer walls of both the left and right ends of the rotating drum, and the annular mounting plates are fixedly installed inside the cooling pool by mounting rods.

[0014] In a preferred embodiment of the present invention, a water tank is provided on the rear side of the cooling box, and a water pump is provided on the upper right end of the water tank. The rear end of the water pump is connected to the bottom of the water tank through a water pumping pipe, the front end of the water pump is connected to the upper right end of the cooling pool through a water inlet pipe, and the lower left end of the cooling pool is connected to the upper left end of the water tank through a water outlet pipe. The height of the water tank is lower than the height of the cooling pool.

[0015] In a preferred embodiment of the present invention, the dewatering mechanism includes a square mounting plate and a square hollow plate. A second motor is provided on the left side of the upper surface of the square mounting plate. A first spur gear is driven to the power output end of the second motor. The first spur gear meshes with a second spur gear. The second spur gear meshes with a U-shaped toothed belt. Push blocks are provided on the outer surface of the U-shaped toothed belt, and four sets of push blocks are arranged in a circumferential array. A vertical rod is provided in the middle of the four sets of push blocks. An L-shaped mounting plate is provided at the lower end of the vertical rod. A water-absorbing sponge is provided inside the L-shaped mounting plate. Two water-absorbing sponges located in the middle are in contact with the outer surfaces of the front and rear ends of the cable, respectively.

[0016] In a preferred embodiment of the present invention, the upper surfaces of the square mounting plate and the square hollow plate are fixedly connected to the inner top wall of the cooling box by a fixed connecting rod. The square mounting plate is disposed inside the square hollow plate, and a U-shaped movable slot is provided between the square mounting plate and the square hollow plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) By setting up an immersion cooling mechanism, the water around the cable can be stirred when the cable is immersed in water for cooling, so that the cable will not exchange heat with the water in the same area. It also generates a leftward thrust in the cooling pool, and the water carrying heat is discharged through the outlet pipe. New cooling water enters the cooling pool, so that the cooling pool is always in a strong cooling effect, which improves the cooling efficiency and cooling effect of the cable.

[0022] (2) The water removal mechanism can remove the moisture from the surface of the cooled cable. During the continuous water removal process, the water-absorbing sponge can be switched and the sponge that has absorbed more water can be squeezed out to get a drier sponge, so as to facilitate the subsequent replacement work. This will maintain a strong water removal effect and prevent residual moisture on the cable surface from affecting the appearance and subsequent work.

[0023] (3) The water mist spraying mechanism and exhaust pipe can be used to pre-treat the cable, so that the cable temperature is reduced before it is submerged in water, thus avoiding the negative impact of sudden cooling and improving the quality of the finished cable.

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 - Figure 7 As shown, an environmentally friendly cooling process for manufacturing fire-resistant aluminum alloy power cables includes pre-cooling treatment, immersion cooling treatment, surface dehydration, and discharge. The process is based on an environmentally friendly cooling device for manufacturing fire-resistant aluminum alloy power cables. The device includes a cooling box 1. Inside the cooling box 1, from left to right, there are a water mist spraying mechanism 2, an immersion cooling mechanism 3, and a dehydration mechanism 4. Two sets of dehydration mechanisms 4 are symmetrically arranged. A cable 7 is placed in the middle of the interior of the cooling box 1. Inlet and outlet holes 5 are opened at both ends of the cooling box 1. The left and right ends of the cable 7 pass through the two inlet and outlet holes 5 respectively. The diameter of the inlet and outlet holes 5 is larger than the diameter of the cable 7, so that the cable 7 can smoothly enter or exit the cooling box 1 through the inlet and outlet holes 5. The left end of the cable 7 passes through the middle of the lower end of the water mist spraying mechanism 2. The middle part of the cable 7 is located inside the immersion cooling mechanism 3. The right side of the cable 7 is located below the dehydration mechanism 4. An exhaust pipe 6 is set at the upper left end of the cooling box 1, and the exhaust pipe 6 is located to the right of the water mist spraying mechanism 2.

[0035] It should be noted that the water mist spraying mechanism 2 consists of a ring-shaped spray pipe and a water injection pipe. The water injection pipe extends from the top of the cooling box 1 to the outside, connecting to an external water pipe to provide cooling water. This allows the water mist spraying mechanism 2 to smoothly spray water mist onto the outer circumference of the cable 7 during operation. The water mist spraying mechanism 2 is characterized by the mixing of compressed air and water to form a fine mist. Utilizing the principle of evaporative heat absorption, it significantly improves cooling efficiency and reduces cooling water consumption. The exhaust pipe 6 connects to an external air pump. When the air pump is working, the exhaust pipe 6 sprays water onto the cooling box. 1. Internal ventilation removes water vapor generated when water mist comes into contact with the surface of cable 7 during spraying, preventing water vapor from accumulating inside the cooling box 1 and condensing, which would then re-adhere to the surface of cable 7 and affect subsequent dehydration. At the same time, when the exhaust pipe 6 draws air from inside the cooling box 1, because the interior of the cooling box 1 is a relatively enclosed space, outside air can only enter the cooling box 1 through the inlet and outlet holes 5, resulting in a faster gas flow at the inlet and outlet holes 5. This pre-treats the cable 7, preventing excessive stress or defects caused by the sudden cooling of the high-temperature melt, and improving the finished product quality of cable 7.

[0036] The immersion cooling mechanism 3 includes a cooling pool 301, which is located in the middle of the bottom of the cooling box 1. Limiting guide rollers 302 are provided on both the left and right sides of the upper end of the cooling pool 301. The inner ends of the two sets of limiting guide rollers 302 abut against the upper and lower sides of the cable 7, respectively. The limiting guide rollers 302 can limit and guide the cable 7 inside the cooling box 1, preventing the cable 7 from shifting during transport. They also provide a thrust to the cable 7, making it move more stably to the right. Pressure rollers 303 are rotatably installed inside the left and right sides of the cooling pool 301, with the lower end of the pressure rollers 303 abutting against the upper surface of the cable 7. The pressure rollers 303 can press down the middle of the cable 7, causing it to be submerged in the water. Then, as the cable 7 is transported from left to right... During the process, the device will be cooled by cooling water. A motor 304 is connected to the front end of the right-side lower limit guide roller 302, and the motor 304 is located on the front right side of the cooling pool 301. The rear end of the right-side lower limit guide roller 302 is connected to a gearbox 306 via a synchronous belt mechanism 305. A worm gear 307 is connected to the output end of the gearbox 306. The front end of the worm gear 307 is rotatably mounted inside the cooling pool 301, and a worm wheel 308 is meshed with the lower end of the worm gear 307. A rotating drum 309 is located in the middle of the worm wheel 308. The gearbox 306 is designed to adjust the rotation speed. Because the cable 7 will not move too fast during transport, while the rotating drum 309 requires a relatively high speed, the gearbox 306 adjusts the rotation speed accordingly. The design prevents the cable 7 from moving too fast, while allowing the rotating drum 309 to rotate rapidly and agitate the water inside the cooling pool 301. The inner wall of the rotating drum 309 is arrayed with several spiral blades 310. The middle part of the cable 7 is positioned inside the rotating drum 309 but does not contact the spiral blades 310. The spiral blades 310 agitate the water inside the cooling pool 301, and their proximity to the cable 7 intensifies the agitation of the water around the cable 7. This prevents the cable 7 from only contacting the surrounding water during cooling, allowing for faster heat exchange and improved cooling efficiency. Annular mounting plates are rotatably connected to the outer walls of both ends of the rotating drum 309. The plate is fixedly installed inside the cooling pool 301 by the mounting rod 311. The ring-shaped mounting plate and the mounting rod 311 can support the rotating drum 309 without affecting its rotation. A water tank 312 is provided on the rear side of the cooling box 1. A radiator is provided on the surface of the water tank 312 to dissipate heat quickly. A water pump 313 is provided on the upper right end of the water tank 312. The rear end of the water pump 313 is connected to the bottom of the water tank 312 through a water pumping pipe. The front end of the water pump 313 is connected to the upper right end of the cooling pool 301 through a water inlet pipe 314. The lower left end of the cooling pool 301 is connected to the upper left end of the water tank 312 through a water outlet pipe 315. The height of the water tank 312 is lower than the height of the cooling pool 301.

[0037] It should be noted that when the spiral blade 310 rotates, it will cause the water inside the cooling pool 301 to generate a leftward thrust. Since the height of the outlet pipe 315 is higher than that of the water tank 312, the water with heat inside the cooling pool 301 will be discharged into the water tank 312 through the outlet pipe 315. At the same time, the water pump 313 works to inject the cooling water inside the water tank 312 into the cooling pool 301 through the inlet pipe 314. This ensures that the water injection and drainage speeds inside the cooling pool 301 are the same, allowing the water inside the cooling pool 301 to be replaced while the water level is always higher than that of the cable 7, thereby cooling the cable 7 more efficiently.

[0038] The water removal mechanism 4 includes a square mounting plate 401 and a square hollow plate 402. The upper surfaces of the square mounting plate 401 and the square hollow plate 402 are fixedly connected to the inner top wall of the cooling box 1 via a fixed connecting rod 8. A second motor 403 is installed on the left side of the upper surface of the square mounting plate 401. The power output end of the second motor 403 is connected to a first spur gear 404. The first spur gear 404 meshes with a second spur gear 405. The second spur gear 405 meshes with a U-shaped toothed belt 406. Driven gears are meshed at the other three inner corners of the U-shaped toothed belt 406. The second spur gear 405 and the three driven gears are all rotatably mounted via a rotating rod. Inside the square mounting plate 401, a U-shaped movable groove is formed. Spur gear 1 404, spur gear 2 405, three driven gears, and the U-shaped toothed belt 406 are all housed within this groove, providing installation and rotation space for these components. Push blocks 407 are provided on the outer surface of the U-shaped toothed belt 406, and four sets of push blocks 407 are arranged in a circumferential array. A vertical rod 408 is located in the center of each of the four sets of push blocks 407. The push blocks 407 and the vertical rod 408 are fixedly connected, thus creating the U-shaped... When the toothed belt 406 drives the push block 407 to move, the vertical rod 408 moves along with the push block 407. Simultaneously, the vertical rod 408 does not rotate. The square mounting plate 401 is located inside the square hollow plate 402, and a U-shaped moving slot 412 is provided between the square mounting plate 401 and the square hollow plate 402. All four vertical rods 408 are slidably installed inside the U-shaped moving slot 412. The U-shaped moving slot 412 provides space for the push block 407 and the vertical rods 408 to move smoothly within the U-shaped moving slot 412. Furthermore, both the upper and lower ends of the vertical rods 408 are equipped with… The limit block 411 improves the stability of the vertical rod 408, making it less likely for the vertical rod 408 to detach from the push block 407. An L-shaped mounting plate 409 is provided at the lower end of the vertical rod 408. The L-shaped mounting plate 409 contains a water-absorbing sponge 410. The two water-absorbing sponges 410 located in the middle contact the outer surfaces of the front and rear ends of the cable 7, respectively. This allows the two water-absorbing sponges 410 to absorb the moisture on the surface of the cable 7 when it is moved from left to right, preventing water stains from forming on the surface of the cable 7 when it dries, or water droplets from falling into the working environment and causing unnecessary trouble.

[0039] A motor 413 is positioned in the center of a square mounting plate 401. The power output end of the motor 413 is connected to a rotating shaft 414. An intermittent gear 415 is mounted on the circumferential surface of the upper end of the rotating shaft 414. A toothed plate 416 is meshed with one side of the intermittent gear 415. The toothed plate 416 is hollow, and its inner walls on both sides are provided with teeth that mesh with the intermittent gear 415. When the intermittent gear 415 meshes with the teeth on one side, it will not mesh with the teeth on the other side. This allows the intermittent gear 415 to drive the toothed plate 416 through its teeth during continuous rotation. The toothed plate 416 moves back and forth. A vertical plate 417 is provided at the end of the toothed plate 416 away from the cable 7. A pressing block 418 is provided on the side wall of the lower end of the vertical plate 417. One side of the pressing block 418 is in contact with a water-absorbing sponge 410 away from the cable 7. A groove 420 is provided on the upper surface of the square mounting plate 401. A positioning slider 419 is slidably installed inside the groove 420. The upper end of the positioning slider 419 is fixedly connected to the lower surface of the toothed plate 416. The positioning slider 419 can limit and support the toothed plate 416 without affecting the horizontal movement of the toothed plate 416.

[0040] The process of this invention, when used, specifically includes:

[0041] Step 1, Pre-cooling treatment: Cable 7 enters the interior of cooling box 1 through the inlet / outlet hole 5 at the left end of cooling box 1. First, start the air pump so that the exhaust pipe 6 draws air into the interior of cooling box 1. The inlet / outlet holes 5 on both sides of cooling box 1 generate negative pressure, thereby generating air that flows rapidly into the interior of cooling box 1. The rapid airflow can pre-treat the surface of cable 7, first reducing the surface temperature of cable 7. Then, it passes through the annular spray pipe of water mist spraying mechanism 2. When water mist spraying mechanism 2 is working, it can spray water mist onto the outer circumference of cable 7, so that the outer circumference of cable 7 is initially cooled.

[0042] Step 2, Immersion Cooling Treatment: Next, cable 7 passes sequentially through the left-side limiting guide roller 302 of the cooling pool 301. Then, pressure roller 303 presses the middle portion of cable 7 into the water. Afterward, cable 7 moves to the right and exits the cooling pool 301 via the right-side limiting guide roller 302. At this time, motor 304 operates, driving the lower right-side limiting guide roller 302 to rotate, providing a rightward traction force to cable 7. Simultaneously, the synchronous belt mechanism 305 drives the gearbox 306 and worm gear 307 to rotate. The worm gear 307 rotates... The worm gear 308 drives the rotating drum 309 and the spiral blade 310 to rotate, which agitates the water around the cable 7 and accelerates the heat exchange between the cable 7 and the water inside the cooling pool 301. At the same time, the rotation of the spiral blade 310 generates a leftward thrust, which allows the water to carry heat and flow out from the left outlet pipe 315 and then into the water tank 312. Meanwhile, the water pump 313 on the right works to pump the cooling water inside the water tank 312 into the cooling pool 301, so that the cooling effect inside the cooling pool 301 is always in a strong state.

[0043] Step 3, Surface Dehydration: After cooling, the cable 7 will continue to move to the right carrying some moisture. During this movement, it will come into contact with the two sets of absorbent sponges 410 in the middle. The absorbent sponges 410 will remove the residual moisture from the surface of the cable 7. After absorbing water for a period of time, the middle absorbent sponge 410 will start motor 2 403. Motor 2 403 will drive spur gear 1 404 to rotate. The rotation of spur gear 1 404 will drive spur gear 2 405 to rotate the U-shaped toothed belt 406. The U-shaped toothed belt 406 will drive the vertical rod 408, L-shaped mounting plate 409, and absorbent sponge 410 to move inside the U-shaped moving channel 412 through push block 407. When the middle absorbent sponge 410 moves to the leftmost end, it is still in contact with the surface of the cable 7. At this time, the absorbent sponge 410 on the right side moves towards the cable 7 and comes into contact with the surface of the cable 7. The first set of absorbent sponges 410 will move away from the cable 7. The absorbent sponge 410 that just came into contact with the cable 7 will move to the middle of the U-shaped moving channel 412 near the cable 7, completing the replacement of the absorbent sponge 410. This allows the absorbent sponge 410 that has absorbed more water to be removed, and the relatively dry absorbent sponge 410 to be moved to the dewatering position for dewatering. Then, the motor 3 413 will be started. The motor 3 413 will drive the rotating shaft 414 and the intermittent gear 415 to rotate. The rotation of the intermittent gear 415 will drive the toothed plate 416 to move back and forth. This will cause the toothed plate 416 to drive the vertical plate 417 and the front and rear edges of the squeezing block 418 to move back and forth. The squeezing block 418 can squeeze the absorbent sponge 410 that is furthest from the cable 7, squeezing out the water inside the absorbent sponge 410, thus obtaining a relatively dry absorbent sponge 410, which is convenient for subsequent replacement.

[0044] Step 4, Discharge: The cable 7, after surface dehydration, is removed from the cooling box 1 through the inlet / outlet hole 5 at the right end of the cooling box 1, so that it can proceed with subsequent work.
