Description

Technical Field

[0001] The utility model relates to atomizing spraying and cooling equipment for cable production. Background Art

[0002] The cable is formed by injection molding. After injection molding, the surface of the cable is in a high temperature state. Before coiling the cable later, the cable needs to be cooled to room temperature to avoid deformation due to the high temperature of the cable when it is not fully hardened.

[0003] There are two main existing cooling methods, one is water cooling and the other is air cooling. Air cooling has a lower cooling efficiency and is therefore less commonly used, while water cooling has a higher efficiency and is more widely used.

[0004] In the prior art, water cooling is performed through a water tank. When the cable passes through the water tank, it contacts with water for heat exchange, thereby achieving cable cooling.

[0005] We found in actual operation that with this cooling method, the heat of the cable is completely absorbed by the water, causing the water in the cooling tank to heat up rapidly, and a very high water change rate is required to maintain the low temperature of the water.

[0006] Therefore, we designed a cable production atomizing spray cooling equipment that can achieve cable cooling and reduce the water change rate. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a cable production atomizing spray cooling device which can realize cable cooling and reduce the water replacement rate.

[0008] The utility model is realized by the following technical solutions:

[0009] A cable production atomizing spray cooling equipment comprises a cooling trough, a water inlet pipe and an overflow pipe are arranged on the side of the cooling trough, the height of the overflow pipe is lower than the height of the water inlet pipe, a valve is installed at the water inlet pipe, a cooling channel is arranged inside the cooling trough, both ends of the cooling channel pass through the cooling trough, guide wheel structures are installed at both ends of the cooling trough, the cable to be cooled is rotatably supported by the guide wheel structures at both ends and passes through the cooling channel, a water pump is installed outside the cooling trough, a water pumping pipe is connected between the water pump and the cooling trough, and a water supply pipe is connected between the water pump and the cooling channel.

[0010] Preferably, the cooling channel includes an outer tube and an inner tube, the length of the inner tube is smaller than that of the outer tube, the inner tube is assembled inside the outer tube, a water tank is formed between the inner tube and the outer tube, a plurality of atomizing nozzles are installed inside the inner tube, the inner wall of the outer tube is provided with water stop grooves at both ends of the inner tube, a water discharge hole is provided at the bottom of the water stop groove, the water discharge hole corresponds to the interior of the cooling tank, the water supply pipe is connected to the outer tube, and is connected to the water tank.

[0011] Preferably, a negative pressure fan is arranged above the outer tube, the negative pressure fan is connected to two air inlet pipes, the air inlet pipes are connected to the outer tube and are located at both ends of the inner tube, and the negative pressure fan discharges air downward.

[0012] Preferably, a ventilation hole is provided on the outer wall of the cooling tank near the top.

[0013] Preferably, the guide wheel structure includes a guide wheel bracket and a wheel axle fixed by the guide wheel bracket, the wheel axle is rotatably engaged with the guide wheel, and a wheel groove for positioning the cable is provided on the outer wall of the guide wheel.

[0014] Preferably, a tank cover is buckled on the top of the cooling tank.

[0015] The beneficial effects of the utility model are:

[0016] When the device cools the cable, the cable is not immersed in water, but cooled by atomizing spray. During the atomizing spraying process, the water mist contacts the surface of the cable evenly, and evaporates after contacting the high-temperature cable to take away the heat. After the temperature of the cable drops, the water after the atomizing spray condenses into larger water droplets after contacting the cable, and flows back to the cooling tank along the outer tube, and most of the heat can be taken away by volatilization. Therefore, the heat in the refluxed water is relatively small, which reduces the water change rate in the cooling tank. Secondly, the water in the cooling tank can be cooled by air cooling, and the volatilized water vapor can be captured under negative pressure and sent back to the cooling tank, reducing the waste of water resources.

[0017] Using a longer cooling channel can extend the contact time with the cable and improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1The cable production atomization spray cooling equipment shown in the figure comprises a cooling tank 1, the length of the cooling tank 1 is 2 to 4 meters. In the present embodiment, the length of the cooling tank 1 is 3 meters, the height is 1 meter, and the width is 0.8 meters. The cooling tank 1 is made of a stainless steel tank with a wall thickness of 8 mm. An inlet pipe 101 and an overflow pipe 102 are arranged on the side of the cooling tank 1. The height of the overflow pipe 102 is lower than the height of the inlet pipe 101. A valve 103 is installed at the inlet pipe 101. When in use, the inlet pipe 101 is always kept in a small flow of water, and the overflow pipe 102 is connected to the back A water pipe is used to recover the continuously overflowing water. A cooling channel 2 is arranged inside the cooling tank 1. The height of the cooling channel 2 is higher than the height of the overflow pipe 102. Both ends of the cooling channel 2 pass through the cooling tank 1. Guide wheel structures 3 are installed at both ends of the cooling tank 1. The cable to be cooled is rotatably supported by the guide wheel structures 3 at both ends and passes through the cooling channel 2. A water pump 4 is installed outside the cooling tank 1. A water pumping pipe 41 is connected between the water pump 4 and the cooling tank 1, and a water delivery pipe 42 is connected between the water pump 4 and the cooling channel 2.

[0028] In the above technical solution, the cable to be cooled is cooled through the cooling channel 2, the cooling time is longer, and the cooling effect is better.

[0029] See also Figure 2 and Figure 3 As shown, the cooling channel 2 includes an outer tube 21 and an inner tube 22. The length of the inner tube 22 is smaller than that of the outer tube 21. The inner tube 22 is assembled in the outer tube 21. A water tank 23 is formed between the inner tube 22 and the outer tube 21. A plurality of atomizing nozzles 24 are installed inside the inner tube 22. The inner wall of the outer tube 21 is provided with water stop grooves 25 at both ends of the inner tube 22. A water discharge hole 26 is provided at the bottom of the water stop groove 25. The water discharge hole 26 corresponds to the interior of the cooling tank 1. The water supply pipe 42 is connected to the outer tube 21 and communicates with the water tank 23.

[0030] In the above technical solution, the cable can be effectively cooled by long-distance atomization spraying. Water flows through the inside of the outer tube, is intercepted by the water stop groove 25, and then flows back into the cooling groove 1, thereby avoiding the outflow of water and realizing the recycling of water.

[0031] See also Figure 2 As shown, a negative pressure fan 221 is arranged above the outer tube 21, and the negative pressure fan 221 is connected to two air intake pipes 222. The air intake pipes 222 are connected to the outer tube 21 and are located at both ends of the inner tube 22. The negative pressure fan 221 discharges air downward.

[0032] Negative pressure can be formed at the outer tube and the inner tube through the negative pressure fan 221, driving air flow and avoiding heat accumulation in the outer tube and inside the outer tube, which is helpful for cooling the cable. Secondly, it can absorb atomized water vapor, which is discharged back into the cooling tank 1, realizing air cooling of the stored water in the cooling tank 1 and reducing the waste of water resources.

[0033] See also Figure 2 As shown, a ventilation hole 133 is provided near the top of the outer wall of the cooling tank 1 .

[0034] The provision of the ventilation holes 133 helps to discharge heat.

[0035] See also Figure 2 As shown, the guide wheel structure 3 includes a guide wheel bracket 31 and a wheel axle 32 fixed by the guide wheel bracket 31, and a guide wheel 33 is rotatably engaged with the wheel axle 32, and a wheel groove 34 for positioning the cable is provided on the outer wall of the guide wheel 33.

[0036] In the above technical solution, the guide wheel 33 can rotate independently, so as to rotate along with the movement of the cable and reduce the movement resistance of the cable.

[0037] See also Figure 1 As shown, a tank cover 199 is buckled on the top of the cooling tank 1.

[0038] The provision of the tank cover 199 can reduce the entry of dust and keep the interior of the cooling tank 1 clean.

[0039] The implementation method is as follows:

[0040] First, open the valve and inject water into the cooling tank through the water inlet pipe until the water overflows from the overflow pipe. At this time, reduce the opening of the valve and maintain a small amount of water inlet. An electronic thermometer can be installed in the cooling tank to monitor the water temperature. Turn on the water pump. At this time, a water mist channel is formed in the inner tube. The cable passes through the inner tube and is cooled by the water mist. The water flows back into the cooling tank and the temperature of the electronic thermometer is observed. When the temperature rises, further open the valve until the return water does not cause the water temperature to rise. After debugging is completed, the cable cooling operation can be realized.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
