Description

Technical Field

[0001] This invention relates to the field of cable production equipment technology, and in particular to a three-stage progressive high-efficiency cable surface drying system and its working method. Background Technology

[0002] After the cables are extruded, they need to be cooled in a water tank, so a lot of cooling water will adhere to the surface. Currently, there are three main methods for drying the surface of cables in the industry: blowing, hot air drying and wiping.

[0003] Hot air drying equipment consumes a lot of energy, and continuous heating generates a large amount of electricity costs. Moreover, the plastic that has just cooled is prone to softening, bulging, and stickiness when heated. When the machine is stopped, the residual heat continues to bake the cables, which can easily cause batch defects in appearance. Therefore, drying equipment usually cannot be used alone and must be used in conjunction with a pre-air knife to blow away more than 90% of the water.

[0004] Wiping methods such as sponges, felts, and absorbent rollers are only suitable for low-speed cables. Once the sponge is saturated with water, it will become completely ineffective and needs to be replaced frequently, which consumes a lot of labor costs. At the same time, sponge fibers and lint are easy to fall off and stick to the surface of the cable, causing dirt. In addition, during high-speed production, fine threads are easily scratched by the sponge, resulting in scratches that affect the appearance.

[0005] Drying is widely used in production. However, as cable production speed continues to increase, traditional annular air knives can no longer meet the water removal requirements under high-speed production conditions. Therefore, there is an urgent need to develop a new type of high-efficiency drying device with optimized structure, adaptability to high-speed cables, low energy consumption, and no damage to the cable surface. Summary of the Invention

[0006] This invention provides a three-stage progressive high-efficiency cable surface drying system and its working method, which solves the problems of high energy consumption, easy damage to cables, and inability to adapt to high-speed production in existing cable drying processes. With pneumatic dehydration and circulating drying as the core, it makes full use of fluid dynamics structure to achieve efficient drying of cable surfaces without dead angles or damage.

[0007] The solution of the present invention to the above-mentioned technical problems is as follows: In the first aspect, a three-stage progressive high-efficiency drying system for cable surfaces and its working method are disclosed, comprising a drying device body, an air-water separation device, an air pump, and a corrugated pipe assembly.

[0008] The main body of the drying device is a closed box, inside which a water blower group, an air blower, and a water absorption plate group are arranged sequentially along the cable travel direction. The main body of the drying device also contains a water baffle group and several cable stabilizers. The water blower group consists of several quick-release square water blowers arranged in series. The air outlet of the air blower is set as a Laval nozzle structure. The bottom of the water absorption plate group has multiple sets of vent holes. The water baffle group divides the inner cavity of the main body of the drying device into multiple independent working chambers.

[0009] The gas-liquid separation device includes a cyclone barrel body, inside which is a spiral impeller and at the top is a filter element.

[0010] The corrugated pipe assembly includes a first corrugated pipe, a second corrugated pipe, and a third corrugated pipe. The first corrugated pipe is connected at both ends to the cavity below the water absorption plate assembly and the lower air inlet of the cyclone barrel. The second corrugated pipe is connected at both ends to the air outlet of the filter element and the air inlet of the air pump. The third corrugated pipe is connected at both ends to the output of the air pump and the air inlet of the blower. Through this closed box structure and the ingenious air path connection of the three corrugated pipes, a complete closed-loop circulating airflow system is constructed, from water absorption and suction to air-water separation, then to air pump pressurization, and finally backflow purging. This greatly reduces the dependence on external compressed air sources and reduces energy consumption.

[0011] Furthermore, the blower assembly consists of several quick-release square blowers arranged in series, and each blower is independently equipped with a solenoid valve to control the airflow. By arranging three blowers in series, a large amount of water adhering to the surface of high-speed cables can be swept away step by step and in stages, significantly improving the water removal efficiency. With the independently controlled solenoid valve, the air volume of a single or combined blower can be precisely adjusted according to the production line speed or the actual water stains on the cable surface. At the same time, the quick-release structure greatly facilitates subsequent individual maintenance and replacement, reducing downtime maintenance costs.

[0012] Furthermore, there are four cable stabilizers, two of which are symmetrically installed on the left and right sides of the blower, and the other two are respectively assembled in the independent working chambers corresponding to the water blower group. By setting full-process guide limits in the key areas of blowing away water and cleaning up residual film, the high-speed cable can be effectively restrained, preventing it from vibrating at high frequency or swaying left and right under the impact of high-pressure airflow. This avoids physical friction between the cable and internal components, thus preventing scratches and ensuring that the cable always travels in a straight line smoothly and accurately. It is particularly suitable for high-speed cable production.

[0013] Furthermore, the inside of the blower assembly is also equipped with a centering adjustment mechanism for correcting the cable's travel position. This centering adjustment mechanism can actively correct the cable's trajectory when the high-pressure airflow acts on the cable, ensuring that the cable is always located in the center of each blower, and ensuring that the high-pressure airflow can evenly wrap around and blow the cable surface in 360 degrees, eliminating dead angles in water removal caused by cable deviation.

[0014] Furthermore, the bottom of the cyclone tank is equipped with a Venturi automatic drainage device. By setting up the Venturi automatic drainage device, the liquid water that has been separated and collected at the bottom of the tank can be automatically discharged to the outside of the system without the need for additional electrical drive equipment. This achieves automated drainage, effectively prevents water from flooding the exhaust channel, and significantly reduces the frequency of manual inspection and cleaning.

[0015] Furthermore, the outer wall of the main body of the drying device adopts a composite structure, which includes a perforated plate, a sound-absorbing cotton layer, and an external heat insulation plate from the inside out. The combination of the perforated plate and the sound-absorbing cotton layer can effectively absorb the aerodynamic noise generated by the operation of the air pump and the high-pressure airflow, significantly reducing noise pollution in the workshop. The external heat insulation plate can isolate the heat generated by the internal airflow from dissipating outward, while preventing the external surface temperature of the equipment from becoming too high, effectively ensuring the safety of the operators.

[0016] Secondly, the present invention also provides a working method based on the above-mentioned three-stage progressive cable surface high-efficiency drying system, comprising the following steps: The cable is fed into the main body of the drying device and passes sequentially through a straight channel formed by a water blower group, an air blower, and a water absorption plate group. The water blower group sprays high-pressure airflow to blow away a large amount of water adhering to the surface of the cable. The cable enters the air blower, where a high-speed airflow from the Laval structure at the end of the air blower powerfully sweeps away the residual water film on the surface of the cable. When the cable reaches the water absorption plate group, the trace amounts of residual water on the surface of the cable are adsorbed by negative pressure through the slanted vents at the bottom of the water absorption plate group, completing the three-stage water removal. This working method forms an all-round, dead-angle-free, and damage-free cleaning path for large amounts of water droplets, sheet-like water films, and extremely small water droplets through a progressive combination of "high-pressure physical removal of large amounts of water, high-speed air curtain of Laval structure to disperse residual water film, and negative pressure adsorption of trace amounts of residual water in dead corners". It has high drying efficiency and does not produce thermal damage.

[0017] During the dehydration process, the water-containing mixed airflow drawn out by the suction plate assembly is sent into the cyclone separator of the air-water separation device through the first corrugated pipe. As the water-containing airflow rises inside the cyclone separator, it is guided by the fixed spiral impeller to form a high-speed rotating airflow. The centrifugal force generated by the rotation of the airflow throws water droplets against the barrel wall, causing them to collect downwards on the inner wall of the cyclone separator. The dried airflow, after the liquid water has been removed, moves upwards and passes through the filter element to filter out fine water mist before entering the air pump through the second corrugated pipe. The air pump pressurizes the dried airflow, and the pressurized clean airflow is sent back to the air inlet of the blower through the third corrugated pipe, realizing the closed-loop recycling of the airflow within the system. The dried gas after gas-liquid separation is directly pressurized and reused, which greatly saves the consumption of external compressed air and significantly reduces production energy consumption. At the same time, the dual protection of the spiral impeller centrifugal force and the filter element ensures the high cleanliness of the circulating airflow and prevents residual impurities from secondary contaminating the cable surface.

[0018] The beneficial effects of this invention are as follows: This invention provides a three-stage progressive high-efficiency drying system for cable surfaces and its working method, which has the following advantages: 1. Highly efficient and thorough water removal: An innovative three-stage progressive water removal structure is proposed. The water blower group handles large amounts of standing water, the Laval blower handles sheet-like water films, and the suction plate group, in conjunction with negative pressure, treats residual water in dead corners. This progressive approach results in extremely high drying efficiency and no blind spots in the drying process.

[0019] 2. Significant energy saving and consumption reduction: The system adopts a Sacramento air-water separator combined with three sets of corrugated pipes to form a closed-loop air circuit. The separated dry air is pressurized by an air pump and then recycled, which can significantly reduce the consumption of external air sources and significantly save the factory's compressed air costs.

[0020] 3. Adapts to high-speed production and protects cables: Through the full-process constraint of the cable stabilizer and the centering adjustment mechanism inside the blower, the cable can remain centered and stable under high-speed travel and high-pressure airflow impact, effectively preventing cable swaying, shaking and the resulting scratches or abrasions.

[0021] 4. Low noise, automation, and easy maintenance: The composite sound insulation structure on the outer wall of the enclosure significantly reduces working noise and improves the production environment; the Venturi automatic drainage device enables automatic drainage without power, and combined with the quick-release design of the blower and independent solenoid valve control, the system has a high degree of automation and extremely low post-maintenance costs.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 13 As shown, the present invention provides a three-stage progressive high-efficiency drying system for cable surfaces and its working method, which is mainly composed of a drying device body 1, an air-water separation device 2, an air pump 3, and a corrugated pipe assembly 4. The drying device body 1 and the air-water separation device 2 are sealed and connected through the corrugated pipe assembly 4 to form a complete closed-loop airflow dewatering circulation structure.

[0029] Specifically, the main body 1 of the drying device is a closed box, serving as the mounting base for all internal functional components. Inside, along the cable travel direction, are arranged a water blower assembly 101, a blower tube 102, and a water absorption plate assembly 103. Additionally, the box also includes a water baffle assembly 104 for space separation and a cable stabilizer 105 for limiting cable position. Figure 2 , Figure 3 and Figure 8 As shown, the blower assembly 101 consists of three sets of quick-release square blowers arranged in series along the cable conveying path. Each square blower is independently equipped with a solenoid valve to control the airflow. Each blower's corresponding independent unit cavity is also equipped with cable stabilizing accessories and a centering adjustment mechanism, which can maintain the cable's center position while correcting its travel position. The blower 102 is located downstream of the blower assembly 101, and its nozzle adopts a Laval nozzle structure (e.g., ...). Figure 6 , Figure 7 As shown), it can effectively increase the purging flow rate. The water suction plate assembly 103 is arranged downstream of the blower 102, and its bottom has multiple sets of oblique air vents (such as...). Figure 10 , Figure 11 As shown), the baffle plate group 104 consists of multiple water-proof baffles, which are respectively set between the three sets of water blowers, air blowers 102 and water absorption plate group 103, dividing the internal space of the box into independent chambers.

[0030] Furthermore, the number of line stabilizers 105 is four, combined with Figure 2 It can be seen that two cable stabilizers 105 are symmetrically installed on the left and right sides of the blower 102, and the remaining two cable stabilizers 105 are respectively installed inside the unit cavity corresponding to the first and second water blowers. The cable is ensured to travel in a straight line through full-process constraint, preventing the cable from deviating and touching the water blowing or water suction components during high-speed operation.

[0031] The air-water separator 2 includes a cyclone separator 201, an air pump 3, and three corrugated pipes, combined with... Figure 4 , Figure 5 and Figure 12 As shown, the inside of the cyclone tank 201 is equipped with a spiral impeller 202, and the upper part of the tank is equipped with a filter element 203. The bottom of the cyclone tank 201 is also equipped with a Venturi automatic drainage device 204 for automatically draining the separated water. The air pump 3 is located on the outside of the cyclone tank 201.

[0032] In this embodiment, the corrugated pipe assembly 4 mainly includes a first corrugated pipe 401, a second corrugated pipe 402, and a third corrugated pipe 403. The two ends of the first corrugated pipe 401 are respectively connected to the air intake chamber below the water absorption plate assembly 103 in the box (i.e., the main body of the drying device 1) and the lower air inlet of the cyclone barrel 201, for drawing water-containing mixed airflow generated at the water absorption plate. The two ends of the second corrugated pipe 402 are respectively connected to the air outlet of the filter element 203 on the upper part of the cyclone barrel 201 and the air inlet of the air pump 3, for conveying the separated and filtered dry gas to the air pump 3. The two ends of the third corrugated pipe 403 are respectively connected to the output end of the air pump 3 and the air inlet of the blower 102, realizing the recycling of clean airflow.

[0033] The specific implementation process for the working method of this system is as follows: After the cable passes through the previous cooling process, a large amount of water stains adhere to its outer surface. The cable is continuously fed into the main body 1 of the drying device at high speed and undergoes multi-stage dehydration treatment along a preset straight channel. First, the cable enters three sets of square water blowers arranged in series (i.e., water blower group 101). Each set of water blowers is controlled by a separate solenoid valve to output high-pressure airflow. When the cable passes through the cavity of a single set of water blowers, the centering adjustment mechanism inside the cavity automatically corrects the position of the cable. With the help of the built-in small cable stabilizing component, the cable is ensured to be transported in the center. The water blower sprays high-pressure airflow to blow away most of the water adhering to the surface of the cable. During this process, a cable stabilizer 105 is installed inside the first and second sets of water blower cavities to continuously limit the cable and prevent the cable from swinging or deviating.

[0034] After the cable leaves the third set of water blowers, it enters the downstream air blower area (i.e., air blower 102). Two cable stabilizers 105 are symmetrically set on both sides of the air blower 102 to further constrain the cable's trajectory. The Laval nozzle at the end of the air blower 102 outputs high-speed compressed airflow to powerfully sweep away the residual water mist on the surface of the cable. The functional areas inside the box are separated by a baffle plate group 104. The splashing water mist and accumulated water generated by the water blowing are blocked by the baffle plate in the corresponding cavity and will not enter other process areas to cause secondary water contamination.

[0035] After the cleaning is completed, the cable continues to the position of the water absorption plate group 103. The water absorption plate group 103 has slanted ventilation holes at the bottom. The air-water separation device 2 generates negative pressure at the same time, and the airflow is drawn upward from the bottom of the water absorption plate group 103 to absorb the trace residual water on the surface of the cable that is difficult to blow off. After the water is removed, the cable is sent out from the end of the box and enters the next production process.

[0036] While the chamber is dewatering, the air-water separation device 2 continues to operate in a continuous cycle: the water-containing mixed airflow generated by the suction plate assembly 103 is transported to the inside of the cyclone barrel 201 through the first corrugated pipe 401. After the water-containing airflow enters the cyclone barrel 201, it is transformed into a high-speed rotating upward airflow under the guidance of the fixed spiral impeller 202. Relying on the centrifugal force generated by the rotation of the airflow, the liquid water droplets carried in the airflow are thrown to the inner wall of the cyclone barrel 201. The water droplets collect downwards along the barrel wall to the bottom of the barrel. The accumulated water is collected and automatically discharged by the Venturi automatic drainage device 204. The airflow after removing the liquid water flows upward and passes through the filter element 203 on the upper part of the barrel to filter fine water mist impurities. The purified dry airflow is transported to the input end of the air pump 3 through the second corrugated pipe 402. After the air pump 3 pressurizes the clean airflow, it is transported to the inside of the blower 102 through the third corrugated pipe 403. The separated and recovered airflow is then put back into the cable purging process, realizing the recycling of airflow and greatly reducing the consumption of air source.

[0037] In addition, to ensure a smooth operating experience under high-intensity pneumatic conditions, the outer wall of the main body 1 of the drying unit adopts a composite structure, which includes a perforated plate, a sound-absorbing cotton layer, and an external heat insulation plate from the inside out. The combination of the perforated plate and the sound-absorbing cotton layer effectively absorbs the pneumatic noise generated by the operation of the air pump and the high-pressure airflow, significantly reducing noise pollution in the workshop. The external heat insulation plate isolates the heat generated by the internal airflow from dissipating outward, preventing the external surface temperature of the equipment from becoming too high and effectively ensuring the safety of the operators.
