Description

Technical Field

[0001] This utility model belongs to the technical field of cable production, and in particular relates to a cooling pipe structure for cable production. Background Technology

[0002] In cable production, cooling is typically achieved through cooling tanks to lower the cable temperature. Current technology often employs non-enclosed structures in these tanks. When the water flow rate is high, cooling water can easily splash out of the tank, leading to water waste and environmental impact. Furthermore, the non-enclosed structure limits the use of ambient temperature water for cooling. To ensure effective cooling, it is necessary to rely on lower-temperature circulating water, which increases the cooling requirements of the circulating water refrigeration system and results in relatively higher energy consumption. Summary of the Invention

[0003] In order to overcome the technical problems described in the background, this utility model provides a cooling pipe structure for cable production, which uses a relatively sealed main cooling pipe to replace the traditional cold water tank, can withstand higher water pressure, and achieves better cooling capacity.

[0004] The technical solution of this utility model is as follows: a cooling pipe structure for cable production, including a water inlet port, a rear vertical pipe, a rear isolation block, a main cooling pipe, a front vertical pipe, a drain port, a front isolation block, a front overflow drain pipe, a rear overflow drain pipe, and a sealing cover. The front end of the main cooling pipe has a downwardly extending front vertical pipe. The lower end of the front vertical pipe has a front isolation block embedded from bottom to top. The front isolation block divides the interior of the front vertical pipe into a first front cavity and a first rear cavity. The first rear cavity communicates with the main cooling pipe. A drain port communicating with the first rear cavity is provided on the side wall of the front vertical pipe. The rear end of the main cooling pipe is fixedly provided with... The vertically extending rear vertical pipe has sealing covers at both ends and at the lower end of the front vertical pipe. A rear isolation block is embedded in the upper end of the rear vertical pipe from top to bottom. The rear isolation block divides the rear vertical pipe into a second front cavity and a second rear cavity. The second front cavity is connected to the main cooling pipe. The part of the rear vertical pipe that extends beyond the upper side of the main cooling pipe has a water inlet corresponding to the second front cavity. The water inlet, the second front cavity, the main cooling pipe, the first rear cavity, and the main cooling pipe form a cooling water flow path. The cable passes through the front vertical pipe, the front isolation block, the main cooling pipe, the rear isolation block, and the rear vertical pipe in sequence to complete the cooling.

[0005] Furthermore, a front overflow drain pipe is provided at the bottom of the front vertical pipe sidewall corresponding to the first front cavity, and a rear overflow drain pipe is provided at the bottom of the rear vertical pipe sidewall corresponding to the second rear cavity.

[0006] Furthermore, the front riser is provided with a cable inlet for the running cable to pass through, the front isolation block is provided with a front sleeve hole for allowing the cable to pass through, the rear isolation block is provided with a rear sleeve hole for allowing the cable to pass through, and the rear riser is provided with a cable outlet for allowing the cable to pass through.

[0007] Furthermore, the sealing cover includes a top cover, a rear bottom sleeve, and a front bottom sleeve. The top cover is nested in the upper end of the rear vertical tube via a threaded connection, and the rear bottom sleeve and the front bottom sleeve are nested in the lower end of the rear vertical tube and the lower end of the front vertical tube via threaded connections, respectively.

[0008] Furthermore, the inlet and outlet ports are connected to the drain and return ports of the external circulating water cooling system via flange connections, respectively.

[0009] The beneficial effects of this invention due to the adoption of the above-mentioned technology are as follows: This invention uses a relatively sealed main cooling pipe to cool the cable, with a high water flow rate, which has better cooling capacity than traditional open tanks. In particular, the high-efficiency cooling reduces the requirement for low temperature cooling water. Water at room temperature or slightly below room temperature can meet most needs, greatly reducing the load on the refrigeration system and significantly reducing overall energy consumption. In addition, the closed circulation system, combined with the overflow recovery structure separated by the front and rear isolation blocks, can effectively prevent water splashing and waste, and keep the production environment dry.

[0016] Example 1: As Figures 1-5As shown, this utility model provides a cooling pipe structure for cable production, including a water inlet port 1, a rear vertical pipe 3, a rear isolation block 15, a main cooling pipe 6, a front vertical pipe 12, a drain port 8, a front isolation block 13, a front overflow drain pipe 10, a rear overflow drain pipe 4, and a sealing cover. The main cooling pipe 6 serves as the main part for cable cooling. The main cooling pipe 6 is placed horizontally and has a triangular bracket 7 in the middle for support. The front end of the main cooling pipe 6 has a downward-extending front vertical pipe 12. The lower end of the front vertical pipe 12 is embedded with a front isolation block 13 from bottom to top. The front isolation block 13 divides the front vertical pipe 12 into a first front cavity and a first rear cavity. The first rear cavity is connected to the main cooling pipe 6. The side wall of the front vertical pipe 12 has a drain port 8 that communicates with the first rear cavity. The rear end of the main cooling pipe 6 is fixedly installed. There is a vertically extending rear vertical pipe 3. The upper and lower ends of the rear vertical pipe 3 and the lower end of the front vertical pipe 12 are respectively covered with sealing covers. The upper end of the rear vertical pipe 3 is embedded with a rear isolation block 15 from top to bottom. The rear isolation block 15 divides the rear vertical pipe 3 into a second front cavity and a second rear cavity. The second front cavity is connected to the main cooling pipe 6. The part of the rear vertical pipe 3 that extends beyond the upper side of the main cooling pipe 6 is provided with a water inlet port 1 corresponding to the second front cavity. The water inlet port 1, the second front cavity, the main cooling pipe 6, the first rear cavity and the main cooling pipe 6 form a cooling water flow path. The cable passes through the front vertical pipe 12, the front isolation block 13, the main cooling pipe 6, the rear isolation block 15 and the rear vertical pipe 3 in sequence to complete the cooling. Due to the relatively sealed characteristics inside the main cooling pipe 6, it can accept a large water pressure, which makes the water flow speed faster and the cooling capacity stronger.

[0017] Specifically, let L be the effective length of the cable within the main cooling pipe 6, and let A be its heat dissipation area. The relationship between the cable temperature and time can be expressed as: , in This indicates the temperature of the cable at time t, expressed in Kelvin (K). Indicates the initial temperature of the cable, in Kelvin (K). This indicates the temperature of the cooling medium, expressed in Kelvin (K). Represents the cooling time constant, expressed as: ; This indicates the density of the cable material, expressed in kg / m³. This indicates the specific heat capacity of the cable material, expressed in J / (kg·K). This indicates the volume of the cable within the cooling section, expressed in m³. This indicates the heat dissipation area of ​​the cable within the cooling section, expressed in m². This represents the convective heat transfer coefficient, with units of W / (m²·K), and its value depends on the flow rate of the cooling water. Its physical properties are determined by; This indicates the velocity of water flow, measured in m / s. This indicates the density of water, expressed in kg / m³. The dynamic viscosity of water is expressed in Pa·s. This represents the thermal conductivity of water, expressed in W / (m·K). This represents the specific heat capacity of water, expressed in J / (kg·K).

[0018] From the above formula, we can see that the time constant... The smaller the value, the faster the cable cools down; and due to the convective heat transfer coefficient... With water flow velocity The water flow velocity increases with the increase of [something], therefore [something] increases. The larger the size, the stronger the cooling capacity.

[0019] To prevent water from overflowing from the main cooling pipe 6 into the factory area when the cable passes through the front isolation block 13 and the rear isolation block 15, the first front cavity and the second rear cavity are used as collection parts for the overflow water. A front overflow drain pipe 10 is provided at the bottom of the side wall of the front vertical pipe 12 corresponding to the first front cavity and communicating with the first front cavity. A rear overflow drain pipe 4 is provided at the bottom of the side wall of the rear vertical pipe 3 corresponding to the second rear cavity and communicating with the second rear cavity. The rear overflow drain pipe 4 and the front overflow drain pipe 10 are respectively connected to the return water port of the external circulating water cooling system.

[0020] The front vertical pipe 12 is provided with a cable inlet 11 for the running cable to pass through, the front isolation block 13 is provided with a front sleeve hole 14 for the cable to pass through, the rear isolation block 15 is provided with a rear sleeve hole 17 for the cable to pass through, and the rear vertical pipe 3 is provided with a cable outlet 16 for the cable to pass through. The centers of the cable outlet 16, the rear sleeve hole 17, the front sleeve hole 14 and the cable inlet 11 are on the same horizontal straight line. The inner diameter of the cable outlet 16 and the cable inlet 11 is about 2mm-5mm larger than the outer diameter of the cable to avoid the cable from contacting the cable outlet 16 or the cable inlet 11. The inner diameter of the rear sleeve hole 17 and the front sleeve hole 14 is about equal to the outer diameter of the cable to minimize the overflow of water from the rear sleeve hole 17 and the front sleeve hole 14. However, due to friction during long-term operation, water will inevitably overflow from the rear sleeve hole 17 and the front sleeve hole 14 under the action of water pressure in the main cooling pipe 6. Therefore, the first front cavity and the second rear cavity are needed as collection parts for overflowing water.

[0021] The sealing cover includes a top cover 2, a rear bottom sleeve 5, and a front bottom sleeve 9. The top cover 2 is nested in the upper end of the rear vertical pipe 3 by a threaded connection, and the rear bottom sleeve 5 and the front bottom sleeve 9 are nested in the lower end of the rear vertical pipe 3 and the lower end of the front vertical pipe 12 by threaded connections, respectively.

[0022] The inlet port 1 and the outlet port 8 are respectively connected to the outlet and return port of the external circulating water cooling system via flanges.

[0023] The external circulating water cooling system includes a return water tank, a water temperature sensor, a semiconductor cooling module, a water pump, and a PLC controller. The return water inlet of the return water tank is connected to the drain port 8, the rear overflow drain pipe 4, and the front overflow drain pipe 10 through pipes. The PLC controller monitors the water temperature in the return water tank through the water temperature sensor and controls the semiconductor cooling module to cool the water in the return water tank. The water pump is connected to the outlet of the return water tank and can pump water into the inlet port 1.
