Description

Technical Field

[0001] This utility model relates to a cooling device, and more particularly to a cable sheath cooling device for cable production. Background Technology

[0002] In existing cable manufacturing processes, water-cooled tanks with injection and drainage components are typically used to cool and shape the cable sheath. The water-cooled tank maintains a relatively stable cooling environment by continuously injecting and draining cooling water, ensuring that the cable sheath can solidify at the appropriate temperature.

[0003] Traditional cooling methods are widely used in industrial production, providing basic support for efficient cable production and quality assurance. However, existing water-cooled tank cooling systems have some significant shortcomings. First, due to the lack of precise temperature control, the temperature of the cooling liquid is difficult to maintain constant, resulting in uneven cooling of the cable sheath and affecting product quality. Second, frequent water injection and drainage operations not only consume large amounts of water resources but also increase production costs, failing to meet the requirements of modern industrial energy conservation and emission reduction. Furthermore, this method has low cooling efficiency and cannot meet the demands of high-precision, high-quality cable production. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the background art, this utility model provides a cable sheath cooling device that reduces water consumption and precisely controls the cooling temperature.

[0005] A cable sheath cooling device includes a pipe, shrouds, a liquid collection frame, a drain pipe, a temperature detector, a temperature controller, a liquid transfer pump, a spray head, and an inlet pipe. The pipe contains a cooling channel, and at least two shrouds are spaced apart along the pipe. Each shroud has a spray chamber inside, which is connected to the cooling channel within the pipe. The cable to be cooled enters the pipe from the right end, passes through the cooling channel and the spray chambers inside the shrouds, and exits from the left end of the pipe. A liquid collection frame is located at the bottom of each shroud, and the internal space of the collection frame is connected to the internal space of the shroud. A drain pipe is located on one side of the front of each collection frame, and the drain pipe is connected to the internal space of the collection frame. A drain pipe is located on the right side of the pipe near each shroud. Temperature detectors are installed on all side pipes, with the detector probes pointing vertically downwards. Temperature controllers are installed at the front of each diaphragm, each with a liquid flow channel and an inlet pipe. Cooling liquid enters the temperature controller through the inlet pipe for temperature regulation. A transfer pump is installed at the top of the temperature controller, with its input end connected to the liquid flow channel inside the temperature controller. Several spray heads are evenly spaced on the top of each diaphragm, with one end of the spray nozzle pointing downwards into the diaphragm. The output end of the transfer pump is connected to the spray head on the same diaphragm via a connecting pipe. The transfer pump transfers the temperature-regulated liquid from the temperature controller into the spray head on the same diaphragm, and the spray head discharges the liquid inside the diaphragm.

[0006] Furthermore, it also includes a reflux pump, a reflux pipe, and a suction pipe. A reflux pump is provided on the lower front side of the diaphragm. The input end of the reflux pump is connected to the inside of the liquid collection frame on the same diaphragm through the suction pipe. The output end of the reflux pump is provided with a reflux pipe, one end of which is connected to the inside of the liquid inlet pipe on a nearby temperature controller.

[0007] Furthermore, it also includes a bellows, an air outlet pipe, and an air inlet connector. The bellows is located on the left side of the pipe, with the lower part of the bellows extending into the upper part of the pipe. Several air outlet pipes are arranged at the lower part of the bellows, with the outlets of the air outlet pipes facing downwards. An air inlet connector is located at the upper part of the bellows.

[0008] Furthermore, it also includes edge strips, with edge strips installed inside the pipe openings at both ends of the pipe.

[0009] Furthermore, it also includes a mounting frame, a cable transfer wheel 1, and a cable transfer wheel 2. The mounting frame is provided inside the enclosure. Two cable transfer wheels 1 are spaced apart on the left and right sides of the lower part of the mounting frame. Two cable transfer wheels 1 are spaced apart on the front and rear sides of the mounting frame. A cable transfer area is formed between cable transfer wheels 1 and cable transfer wheels 2. When the cable passes through the enclosure, it will pass through the cable transfer area between cable transfer wheels 1 and cable transfer wheels 2.

[0010] The beneficial effects are: by setting multiple spray zones on the cooling channel and gradually reducing the temperature of the spray liquid in each spray zone according to the direction of cable transmission, a stepped temperature control effect from high temperature to low temperature is formed, which ensures that the cable sheath is properly cooled at different stages, reduces water consumption, avoids quality problems caused by uneven cooling, ensures uniform curing of the cable sheath, and improves cooling efficiency and energy utilization.

[0011] This invention uses a reflux pump to return liquid at a certain temperature to the temperature controller. The spray liquid collected in the collection box is then reheated or cooled to the required temperature in the temperature controller before being sent back into the cooling channel, effectively saving water and energy.

[0012] This invention rationally arranges multiple cable conveyor rollers within the cooling channel to ensure that the cable can pass through each spray zone smoothly and in a straight line. The cable conveyor rollers are designed with low-friction materials and equipped with a precision guiding device, which keeps the cable stable during transmission and avoids uneven cooling and surface damage caused by cable shaking or deviation.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] A cable sheath cooling device, such as Figure 1-4 As shown, it includes a pipe 1, a shroud 2, a liquid collection frame 3, a drain pipe 31, a temperature detector 4, a temperature controller 5, a liquid transfer pump 51, a spray head 52, and a liquid inlet pipe 53. The pipe 1 is equipped with a cooling channel. Multiple shrouds 2 are spaced along the pipe 1. Each shroud 2 has a spray chamber inside. During processing, the cable that needs to be cooled is guided to enter from the right end of the pipe 1, pass through the cooling channel and the spray chambers in all the shrouds 2 to the right, and finally exit from the left end of the pipe 1. These spray chambers are all connected to the cooling channel in the pipe 1.

[0022] A temperature controller 5 is installed at the front of the diaphragm 2. The temperature controller 5 has a liquid flow channel inside and is equipped with an inlet pipe 53. Cooling liquid enters the liquid flow channel of the temperature controller 5 from the inlet pipe 53 for temperature regulation, ensuring that the temperature of the cooling liquid in each diaphragm 2 is kept within the optimal range. Multiple spray heads 52 are installed on the upper part of each diaphragm 2.

[0023] The temperature controller 5 is equipped with a liquid transfer pump 51 on its upper part. The input end of the liquid transfer pump 51 is connected to the liquid flow channel inside the temperature controller 5, and the output end of the liquid transfer pump 51 is connected to the spray head 52 through the connecting pipe. The temperature-adjusted cooling liquid is delivered to multiple spray heads 52 on the same partition 2 through the liquid transfer pump 51. One end of the spray nozzle of the spray head 52 is inserted downward into the partition 2. When the spray head 52 is working, the cooling liquid can be evenly sprayed on the surface of the cable in the cooling channel, ensuring that the cooling liquid can stably and evenly cover the entire spray area.

[0024] like Figure 1 and Figure 2 As shown, a temperature detector 4 is installed on the right side of each diaphragm 2 on the pipe 1. The detector probe is vertically downward. The temperature detector 4 monitors the temperature of the cables passing through the cooling channel in real time. Based on the data fed back by the temperature detector 4, the temperature controller 5 installed at the front of the diaphragm 2 on the left side can regulate the temperature of the cooling liquid entering the diaphragm 2. In addition, a liquid collection frame 3 is provided at the bottom of the diaphragm 2. The internal space of the liquid collection frame 3 is connected to the internal space of the diaphragm 2. After the sprayed liquid falls, it will collect in the liquid collection frame 3. A drain pipe 31 is provided on one side of the front of each liquid collection frame 3. The drain pipe 31 is connected to the internal space of the liquid collection frame 3. The liquid is discharged from the liquid collection frame 3 through the drain pipe 31.

[0025] In particular, multiple temperature controllers 5 perform stepped temperature control from right to left, and the temperature of the spray liquid in each spray zone gradually decreases, forming a stepped temperature control effect from high temperature to low temperature.

[0026] Specifically, the cable requiring cooling enters from the right end of pipe 1, passes through the cooling channel and the spray chamber inside the shroud 2, and finally exits from the left end of pipe 1. Cooling liquid enters the liquid flow channel inside the temperature controller 5 from the inlet pipe 53. The temperature controller 5 adjusts the temperature of the cooling liquid according to the data fed back by the temperature sensor 4 on its right side to reach the set value. The liquid pump 51 then delivers the temperature-adjusted cooling liquid from the temperature controller 5 through connecting pipes to multiple spray heads 52 on the same shroud 2. The spray heads 52 evenly spray the cooling liquid onto the surface of the cable, achieving a cooling effect. During this process, the cooling liquid flows into the collection box 3 and is discharged or recycled through the drain pipe 31. Along the cable transmission route, multiple temperature controllers 5 provide stepped temperature control from right to left, meaning the temperature of the spray liquid in each enclosure 2 gradually decreases, forming a gradient from high to low temperature. The cable passes through multiple spray zones sequentially, gradually cooling down until it reaches the ideal curing state. This stepped temperature control design avoids drastic temperature changes in the cable within a short period, preventing uneven cooling or surface damage caused by excessive temperature differences. Simultaneously, the gradual cooling method helps improve the curing quality of the cable sheath, ensuring its uniformity and stability.

[0027] Example 2

[0028] Based on Example 1, such as Figure 1 and Figure 2As shown, it also includes a reflux pump 6, a reflux pipe 61, and a liquid extraction pipe 62. Each of the lower front sides of the diaphragm 2 is equipped with a reflux pump 6. The input end of the reflux pump 6 is connected to the inside of the liquid collection frame 3 on the same diaphragm 2 through the liquid extraction pipe 62, and is used to extract the liquid in the liquid collection frame 3. The output end of the reflux pump 6 is equipped with a reflux pipe 61. One end of the reflux pipe 61 is connected to the inside of the liquid inlet pipe 53 on the adjacent thermostat 5, so that the cooling liquid with a certain temperature is reintroduced into the thermostat 5 for temperature adjustment again. Specifically, after the spray liquid flows into the liquid collection frame 3 and accumulates to a certain amount, the reflux pump 6 extracts it through the liquid extraction pipe 62 and delivers it to the liquid inlet pipe 53 of the adjacent thermostat 5 through the reflux pipe 61. During this process, according to the reflux flow rate of the reflux pump 6, the system can dynamically adjust the flow rate of the new cooling liquid introduced from the outside into the liquid inlet pipe 53 to ensure that the total amount of liquid and temperature in the system are always kept at the optimal state. In this way, the cooling system can operate more efficiently and avoid energy waste and temperature fluctuations caused by excessive introduction of new cooling liquid. In addition, the introduction of the reflux system enables the cooling liquid to form a closed loop circulation between different shrouds 2, further improving cooling efficiency and uniformity.

[0029] Among them, such as Figure 1 and Figure 3 As shown, it also includes a bellows 7, an air outlet 71, and an air inlet connector 72. The bellows 7 is located on the left side of the pipe 1, with its lower part inserted into the upper part of the pipe 1 to ensure precise and stable installation. Several air outlet ducts 71 are arranged at the lower part of the bellows 7, with their openings facing downwards, allowing cooling air to be directly sprayed onto the cable surface for additional cooling. An air inlet connector 72 is located at the upper part of the bellows 7, connecting to an external air source or fan to ensure a continuous and stable supply of cooling air. Simultaneously, the air outlet ducts 71 in the bellows 7 evenly spray cooling air onto the cable surface, further accelerating the cooling process. Because the openings of the air outlet ducts 71 face downwards, the cooling air can be concentrated on the parts of the cable that need cooling. Combined with residual liquid on the cable, this improves cooling efficiency. The combination of liquid and air cooling enhances the cooling effect. During processing, the cable transmission speed can be appropriately increased according to actual production needs, thereby improving production efficiency.

[0030] In addition, such as Figure 1 and Figure 2 As shown, it also includes a side strip 8. The pipe openings at both ends of the pipe 1 are provided with side strips 8. The side strips 8 form an effective annular barrier by tightly fitting against the inner wall of the pipe 1, preventing liquid leakage. This design not only reduces the waste of cooling liquid, but also avoids equipment failure or safety hazards that may be caused by liquid leakage. At the same time, the presence of the side strips 8 helps to maintain the sealing of the cooling environment.

[0031] Finally, as Figure 4 and Figure 5 As shown, the system also includes a mounting frame 9, a first transmission wheel 91, and a second transmission wheel 92. Each partition 2 contains a mounting frame 9. Two first transmission wheels 91 are spaced apart on the lower left and right sides and front and rear sides of each mounting frame 9. These first transmission wheels 91 are connected to the mounting frame 9 via bearings, ensuring free rotation and reducing cable friction during transmission. A transmission area is formed between the first transmission wheel 91 and the second transmission wheel 92, which are also fixed to the mounting frame 9. When the cable passes through the partition 2, it passes through this transmission area. Specifically, the design of the first transmission wheel 91 and the second transmission wheel 92 not only provides stable support for the cable but also effectively reduces cable vibration during transmission. Simultaneously, it ensures that the cable always stays on the optimal transmission path, avoiding quality problems caused by deviation or twisting. The surface of the transmission wheels is made of a highly wear-resistant material, maintaining low friction and high durability during long-term operation, further improving the stability and reliability of the system.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
