Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment, specifically to a multi-stage cooling and shaping device for a cable grouting extruder. Background Technology

[0002] In the field of cable grouting extrusion molding, the cable protective layer extruded at high temperatures needs to be cooled and shaped to ensure its physical properties. In the past, due to the high price of electrical control equipment and online measuring equipment, the mainstream cooling method was open water tank cooling, which involves introducing the cable into a continuous cooling water tank and achieving cooling through natural convection of the water.

[0003] Theoretically, to avoid thermal stress caused by rapid temperature changes, multi-stage cooling is needed for optimal cooling of the cable protective layer. This involves setting a higher cooling water temperature at the very beginning of the cooling tank and gradually controlling the temperature decrease in a gradient, keeping the temperature difference between the cable protective layer and the cooling water within an optimal range. Different cooling methods should be used at different cooling water temperatures. However, in traditional cooling tanks, due to the continuous connection of the tank body, a high-temperature zone forms at the cable inlet, while a medium-low temperature zone forms at the middle and rear ends of the cable. The high-temperature zone and the medium-low temperature zone are in direct contact with the water, and heat is rapidly conducted through the water medium, resulting in a generally high water temperature throughout the tank. This leads to poor cooling in the middle and rear sections of the cable. Increasing the amount of new cooling water to lower the overall tank temperature results in an excessively low cooling water temperature at the cable inlet. This is the contradiction in the use of existing cooling tanks.

[0004] Therefore, in order to manufacture higher quality cables, a multi-stage cooling and shaping device for cable grouting extruders was designed. Multi-stage cooling was achieved by using electrical control equipment and online measuring equipment, thereby improving the physical properties of the cable protective layer after cooling and improving cable quality. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage cooling and shaping device for a cable grouting extruder to solve the problems described in the background art.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A multi-stage cooling and shaping device for a cable grouting extruder includes an outer water tank with a raised bottom and an open top. A controller is located outside the outer water tank. The device is characterized by: multiple blocking components dividing the interior of the outer water tank from left to right into multiple separate and non-communicating compartments; each compartment has a water outlet pipe connected to its bottom; and each compartment contains a cooling pool. The cooling pool includes one rear cooling pool and at least two front cooling pools. The rear cooling pool is located in the last compartment on the right side of the outer water tank. The cooling pools in the compartments to the left of the rear cooling pool are all front cooling pools. Multiple external guide rollers are rotatably mounted in each compartment, with their front and rear ends rotatably passing through the front and rear side walls of the outer water tank, respectively. An online infrared thermometer is located between two adjacent cooling pools on the right side of each front cooling pool. The left and right sides of each cooling pool have a first opening from the top downwards. The left and right inner side walls of each cooling pool also have top-opening placement compartments, whose walls also have openings from the top downwards. The second opening, together with the first and second openings, forms an insertion channel. A removable, top-to-bottom-insertion overflow buffer is inserted into the placement chamber. This buffer elastically wraps around the cable and slows the rate at which liquid overflows from the cooling pool through the insertion channel. Overflow holes are also provided on the front or rear sidewall of the cooling pool. A temperature sensor is installed inside the cooling pool. A second water inlet pipe is located at the top of the cooling pool, with one end extending into the cooling pool and the other end connected to a second water pump located outside the outer pool. The cooling tank is also equipped with a first water inlet pipe. One end of the first water inlet pipe extends into the front cooling tank and is connected to a water spray assembly for spraying water onto the outer surface of the cable. The other end of the first water inlet pipe is also connected to a first water pump located outside the outer water tank. The rear cooling tank is also equipped with multiple inner guide rollers arranged at intervals in the left-right direction. The front and rear ends of the inner guide rollers are respectively rotatably inserted into the front and rear side walls of the rear cooling tank. The first water pump, the second water pump, the temperature sensor, and the online infrared thermometer are all electrically connected to the controller.

[0008] A further technical solution is that the blocking component is a pair of first partitions, each pair of first partitions comprising two first partitions spaced apart from each other, with a gap formed between the two first partitions to isolate the conduction of liquid heat between adjacent compartments.

[0009] A further technical solution is that two bottom plates are fixedly installed inside the cooling pool. The left side of one bottom plate is fixedly connected to the left side wall of the cooling pool, and the right side of the other bottom plate is fixedly connected to the right side wall of the cooling pool. The front and rear ends of the two bottom plates are respectively fixedly connected to the front and rear side walls of the cooling pool. A second partition is also fixedly installed on the right side of the upper end face of the bottom plate located on the left side inside the cooling pool, and a second partition is also fixedly installed on the left side of the upper end face of the bottom plate located on the right side inside the cooling pool. A second opening is opened downward at the top of the second partition. The first opening and the second opening cooperate to form the placement channel. The second partition, the bottom plate and the side wall of the cooling pool together form the placement chamber.

[0010] A further technical solution is that the overflow buffer includes an upper baffle and a lower baffle. The bottom of the upper baffle has an upper semi-circular groove, and the top of the lower baffle has a lower semi-circular groove. Semi-circular foam is fixed on the surface of both the upper and lower semi-circular grooves. The lower baffle is first placed in the placement chamber and placed at the bottom of the placement chamber. The upper baffle is placed above the lower baffle. The upper and lower semi-circular grooves together form a circular groove, and the central axis of the circular groove extends in the left-right direction.

[0011] A further technical solution is that the water spray assembly includes a water distribution network and four straight water supply pipes. The four water supply pipes are respectively located around the cable in the cooling pool. The central axis of the water supply pipes extends in the left-right direction. The four water supply pipes are arranged at equal angles with the central axis of the cable as the axis. At the same time, the top of the water distribution network is left with a cable laying port to facilitate the smooth introduction of the cable. The water supply pipes are also located in a position that does not interfere with the cable laying port. Multiple branch pipes are also connected to the pipe wall of the water supply pipes. Duckbill nozzles are installed on the branch pipes. The duckbill nozzles are inclined to the outer wall of the cable and spray onto the cable.

[0012] A further technical solution is that the spray angle of the duckbill nozzle is 30-35° with the central axis of the cable.

[0013] A further technical solution is to fix a water pipe support at the bottom of the pre-cooling pool, which is used to fix two of the four water supply pipes.

[0014] A further technical solution is to place the overflow hole 5-8 centimeters higher than the top of the cable.

[0015] A further technical solution is that mounting brackets are also fixed on the front or rear sidewall of the outer water tank. The number of mounting brackets is the same as the number of pre-cooling tanks. Each pre-cooling tank has a mounting bracket on its right side. An online infrared thermometer is installed on the mounting bracket. The online infrared thermometer is used to test the external temperature of the cable passing between two adjacent cooling tanks.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Multi-stage cooling and independent control: The outer water pool is divided into multiple independent compartments by multiple pairs of first partitions. Each compartment is equipped with a cooling pool to achieve multi-stage cooling. The heat transfer between different cooling pools is isolated, and the temperature of each cooling pool can be controlled independently to meet the needs of different cooling stages.

[0018] 2. Flexible adaptation to different cable specifications: The number of chambers and the number of pre-cooling pools can be adjusted according to the outer diameter of the cable to be cooled. The larger the outer diameter, the more pre-cooling pools there are and the longer the post-cooling pool is, which can flexibly adapt to different cable specifications.

[0019] 3. Precise temperature measurement and intelligent control: An online infrared thermometer is set up to measure the external temperature of the cable between adjacent cooling pools, and a temperature sensor is installed inside the cooling pool to measure the liquid temperature. Both are electrically connected to the controller, which can realize precise temperature measurement and intelligent control of the coolant temperature according to the preset temperature.

[0020] 4. High-efficiency cooling structure: The pre-cooling pool is equipped with a first water inlet pipe, water distribution network, water supply pipe and duckbill nozzles. The duckbill nozzles spray at an angle toward the outer wall of the cable, which can remove the high-temperature coating water layer and water vapor, improve the exchange rate between the cooling water and the outer wall of the cable, and enhance the cooling effect.

[0021] 5. Effective anti-overflow design: The cooling pool is equipped with a first opening and a second opening to form an insertion channel. The placement chamber is equipped with a slow-overflow component that elastically wraps the cable and slows down the liquid overflow speed. It is also equipped with an overflow hole to ensure that the liquid level in the cooling pool submerges the cable and prevents a large amount of liquid from overflowing. Attached Figure Description

Detailed Implementation

[0029] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0030] See Figures 1 to 6 A multi-stage cooling and shaping device for a cable grouting extruder includes an outer water tank 1, which is a cuboid container with an open top and an elevated bottom.

[0031] For ease of description and understanding, unless otherwise specified, the left and right directions (including but not limited to the left side direction, right side direction, left end direction, and right end direction) refer to the horizontal directions extending left and right along the length of the outer water tank 1, and the front and rear directions (including but not limited to the front side direction, rear side direction, front end direction, and rear end direction) refer to the horizontal directions that are perpendicular to the left and right directions.

[0032] The outer water tank 1 is internally equipped with multiple pairs of first partitions 3. Each pair of first partitions 3 includes two first partitions 3 spaced apart from each other on the left and right. The multiple pairs of first partitions 3 are spaced apart in the left and right direction, dividing the interior of the outer water tank 1 into multiple separate and non-connected compartments. An air gap 4 is formed between each pair of first partitions 3 to isolate the liquid heat conduction between adjacent compartments. The bottom of each compartment is connected to a water outlet pipe 7, which is connected to an external return water collection device.

[0033] It should be noted that the water return collection device refers to a device used to recover the water discharged from the external water tank 1 and transport the recovered water to the external cooling equipment. The water return collection device is a commonly used technical means in the prior art. It can be a water storage tank or water storage pool lower than the external water tank 1 plus a water pump. The external cooling equipment can be an electric cooling device, a cooling tower, or other cooling water devices commonly used in industry. The specific structure and principle of the water return collection device and the external cooling equipment will not be described in this disclosure. Those skilled in the art can configure the water return collection device and the external cooling equipment according to the existing technical means.

[0034] Each compartment is equipped with a cooling pool. The cooling pool is divided into a front cooling pool 9 and a rear cooling pool 10. The rear cooling pool 10 is located in the last compartment on the right side of the outer water pool 1. The cooling pools in the compartments to the left of the rear cooling pool 10 are all considered as front cooling pools 9.

[0035] It should be noted that the number of tanks and the number of pre-cooling pools 9 are adjusted according to the outer diameter of the cable 8 to be cooled. In principle, the larger the outer diameter of the cable 8 to be cooled, the more pre-cooling pools 9 there are and the longer the post-cooling pool 10 is. In principle, the number of pre-cooling pools 9 should not be less than two.

[0036] Multiple outer guide rollers 2 are rotatably installed inside the silo. The front and rear ends of the outer guide rollers 2 are respectively rotatably inserted into the front and rear side walls of the outer water tank 1. The middle part of the outer guide rollers 2 is a U-shaped or V-shaped structure that gradually inwards, used to receive the cable 8, providing support and rightward movement for the cable 8 (it also provides leftward movement, but in this disclosure, the rightward movement function is mainly used). The outer guide rollers 2 are located inside the silo and outside the cooling tank.

[0037] An installation bracket 5 is also fixed on the front or rear side wall of the outer water tank 1. The number of installation brackets 5 is the same as the number of pre-cooling tanks 9. An installation bracket 5 is provided on the right side of each pre-cooling tank 9. An online infrared thermometer 6 is installed on the installation bracket 5. The online infrared thermometer 6 is used to test the external temperature of the cable 8 passing between two adjacent cooling tanks.

[0038] The outer water tank 1 is also equipped with a controller 31. The controller 31 is an STM32 microcontroller or a SMART200 PLC controller 31. The online infrared thermometer 6 is electrically connected to the controller 31.

[0039] The left and right walls of the cooling pool are provided with a first opening 32 that opens downward from the top. Two bottom plates 21 are also fixed inside the cooling pool. The left side of one bottom plate 21 is fixedly connected to the left side wall of the cooling pool, and the right side of the other bottom plate 21 is fixedly connected to the right side wall of the cooling pool. The front and rear ends of the two bottom plates 21 are respectively fixedly connected to the front and rear side walls of the cooling pool. A second partition 12 is also fixedly provided on the right side of the upper end face of the bottom plate 21 located on the left side of the cooling pool. A second partition 12 is also fixedly provided on the left side of the upper end face of the bottom plate 21 located on the right side of the cooling pool. A second opening 33 is opened downward from the top of the second partition 12. The first opening 32 and the second opening 33 cooperate to form an insertion channel. The second partition 12, the bottom plate 21 and the side wall of the cooling pool together form a placement compartment.

[0040] A removable, top-to-bottom-inserted overflow buffer 13 is placed inside the placement chamber. The cable 8 is placed into the cooling pool through the placement channel. The overflow buffer 13 is used to elastically wrap the outside of the cable 8 and slow down the rate at which the liquid in the cooling pool overflows from the placement channel, so that the liquid level in the cooling pool can be higher than the bottom of the first opening 32 and the second opening 33 and submerge the cable 8.

[0041] Specifically, the overflow buffer 13 includes an upper baffle 24 and a lower baffle 25. The bottom of the upper baffle 24 is provided with an upper semi-circular groove 26, and the top of the lower baffle 25 is provided with a lower semi-circular groove 27. The surfaces of the upper semi-circular groove 26 and the lower semi-circular groove 27 are both bonded with semi-circular foam 28. The lower baffle 25 is first placed in the placement chamber and placed at the bottom of the placement chamber. The upper baffle 24 is placed above the lower baffle 25. The upper semi-circular groove 26 and the lower semi-circular groove 27 together form a circular groove, and the central axis of the circular groove extends in the left and right direction.

[0042] During installation, first insert the lower stop block 25 into the placement chamber, then introduce the cable 8 along the insertion channel and place it in the lower semi-circular groove 27, and finally insert the upper stop block 24 to complete the enclosure. The liquid in the cooling pool that is higher than the first opening 32 and the second opening 33 overflows into the outer water pool 1 through the foam 28 and the gap between the overflow buffer 13 and the placement chamber.

[0043] It should be noted that the outer wall of the overflow buffer 13 does not need to be completely fitted to the wall of the storage chamber to form a closed state. In the design, it is only necessary to ensure that the amount of water overflowing through the overflow buffer 13 is less than the amount of water entering the cooling pool.

[0044] An overflow hole 17 is also provided on the front or rear side wall of the cooling pool. The height of the overflow hole 17 should be higher than the top of the cable 8. The optimal setting is that the height of the overflow hole 17 is 5-8 cm higher than the top of the cable 8. When the liquid in the cooling pool is higher than the overflow hole 17, it overflows into the outer water pool 1 through the overflow hole 17.

[0045] A second water inlet pipe 16 is also provided at the top of the cooling pool. One end of the second water inlet pipe 16 extends into the cooling pool, and the other end is connected to a second water pump 23. The second water pump 23 is located outside the outer water pool 1, and its inlet is connected to the outlet of the external cooling equipment. Each cooling pool corresponds to a separate second water pump 23, which is electrically connected to the controller 31. The second water inlet pipe 16 can be installed on the top of the cooling pool or fixed using appropriate support components; these are conventional technical methods and will not be described in detail here.

[0046] A temperature sensor 14 is also installed in the cooling pool. The temperature sensor 14 can be a thermocouple temperature sensor 14. The temperature sensor 14 is used to test the liquid temperature in the cooling pool. The temperature sensor 14 is electrically connected to the controller 31.

[0047] The difference between the pre-cooling tank 9 and the post-cooling tank 10 is that the pre-cooling tank 9 is also equipped with a first water inlet pipe 15. One end of the first water inlet pipe 15 extends into the pre-cooling tank 9 and is connected to a water distribution network 29. Four straight water supply pipes 18 are connected to the water distribution network 29. The four water supply pipes 18 are respectively located around the cable 8 in the cooling tank. The central axis of the water supply pipes 18 extends in the left-right direction. The four water supply pipes 18 are arranged at equal angles with the central axis of the cable 8 as the axis. At the same time, the top of the water distribution network 29 is left with a cable laying port 30 to facilitate the smooth introduction of the cable 8. The water supply pipes 18 are also located in a position that does not interfere with the cable laying port 30. Multiple branch pipes 19 are also connected to the pipe wall of the water supply pipes 18. Duckbill nozzles 20 are installed on the branch pipes 19. The duckbill nozzles 20 are inclined to the outer wall of the cable 8 and spray onto the cable 8. The other end of the first water inlet pipe 15 is also connected to the first water pump 22. The first water pump 22 is located outside the outer water tank 1. The water inlet of the first water pump 22 is connected to the water outlet of the external cooling equipment. The first water pump 22 is electrically connected to the controller 31.

[0048] Preferably, the spray angle of the duckbill nozzle 20 is 30-35° with the central axis of the cable 8.

[0049] Preferably, a water pipe bracket 34 is fixed at the bottom of the pre-cooling pool 9. The water pipe bracket 34 is used to fix two of the four water supply pipes 18. The water supply pipes 18, the water distribution network 29, and the first water inlet pipe 15 are rigidly connected. Due to the characteristics of the rigid structure, the positions of the water supply pipes 18, the water distribution network 29, and the first water inlet pipe 15 can be fixed by fixing two water supply pipes 18. Of course, other methods can also be used to fix the water supply pipes 18, the water distribution network 29, and the first water inlet pipe 15. These are conventional technical means and will not be described in detail here.

[0050] It should also be noted that there are multiple ways to connect the water distribution network 29. The attached diagram only provides one more practical and common connection method, which is characterized by a cable laying port 30 reserved at the top. Those skilled in the art can also adjust the connection structure of the water distribution network 29 according to the actual situation, just pay attention to the reserved cable laying port 30.

[0051] The post-cooling tank 10 does not have a water supply pipe 18, a water distribution network 29, or a first water inlet pipe 15. Instead, it is equipped with multiple inner guide rollers 11 arranged at intervals in the left-right direction. The front and rear ends of the inner guide rollers 11 are respectively rotatably inserted into the front and rear side walls of the post-cooling tank 10. The middle part of the inner guide rollers 11 is a U-shaped or V-shaped structure that gradually inwards, used to receive the cable 8 and provide support and rightward movement for the cable 8 (it also provides leftward movement, but the rightward movement function is mainly used in this disclosure).

[0052] The operating principle of this device is as follows: Taking a cable 8 as an example, after the grout is extruded from the cable 8, it first enters the upper part of the outer water tank 1, then passes through multiple pre-cooling tanks 9, and finally exits through the post-cooling tank 10. The temperature range of the outer sheath of the cable 8 after grout extrusion is 150℃-180℃. When passing through the cooling tanks, the temperature difference between the coolant in the cooling tank and the external temperature of the cable 8 needs to be set to 70-90℃, with a minimum of ambient temperature ±5℃. When passing through the first pre-cooling tank 9, the temperature of the coolant in the first pre-cooling tank 9 needs to be set to 80-90℃. The coolant temperatures of subsequent pre-cooling tanks 9 and post-cooling tanks 10 are adjusted based on subsequent actual measurements.

[0053] When a cable 8 passes through the first pre-cooling tank 9 on the left, the first water pump 22 supplies water to the first inlet pipe 15. The water flows through the distribution network 29 into the supply pipe 18 and is sprayed from the duckbill nozzle 20, spraying onto the outer wall of the cable 8 to remove the high-temperature coating of water and moisture formed on its surface. By increasing the exchange rate between the cooling water and the outer wall of the cable 8, the cooling effect of the cable 8 is improved. The temperature sensor 14 in the pre-cooling tank 9 measures the water temperature and feeds it back to the controller 31. The controller 31, based on the preset temperature, controls the second water pump 23 to supply water to the second inlet pipe 16 to control the temperature of the coolant in the pre-cooling tank 9. The heated coolant flows into the outer water tank 1 through the overflow component 13, the opening, and the overflow hole 17, and is discharged through the outlet pipe 7 at the bottom of the outer water tank 1. By setting the first partition 3 to form an isolation section 4, the water temperature between different compartments is prevented from affecting each other, which is more conducive to the individual control of the coolant temperature in each cooling tank.

[0054] After cable 8 exits from the first pre-cooling tank 9, the outer surface temperature of cable 8 between the first and second pre-cooling tanks 9 is measured by an online infrared thermometer 6. The temperature of the coolant in the second pre-cooling tank 9 is set based on the measured outer surface temperature of cable 8. For example, if the outer surface temperature of cable 8 is measured to be 125℃ after passing through the first pre-cooling tank 9, then the second pre-cooling tank 9 needs to control the coolant temperature between 35℃ and 55℃. Generally, a higher temperature is selected, i.e., 55℃. The smaller the temperature difference between the coolant and cable 8 within the range, the better the cooling effect on the protective layer of cable 8 (the cooling effect here does not refer to cooling efficiency, but rather the physical properties of the protective layer of cable 8 after cooling).

[0055] When the external temperature of cable 8 is below 80°C, the pre-cooling pool 9 will no longer be installed, and the post-cooling pool 10 will be used for cooling instead.

[0056] It should be noted that when the cooling principle of this device is applied in practice, the configuration needs to be adjusted according to actual parameters such as the length of the pre-cooling pool 9, the spray flow rate of the duckbill nozzle 20, and the specifications of the cable 8. These can be achieved by those skilled in the art through a limited number of experiments or calculations. Therefore, detailed device parameters are not given in this disclosure.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
