Description
Technical Field
[0001] This application relates to the field of cable processing equipment technology, and in particular to a blow-suction drying device for efficiently drying materials. Background Technology
[0002] Cable fabrication is a critical step in cable manufacturing. After cabling, cables typically undergo cooling or cleaning in water tanks, leaving a significant amount of moisture on their surface. To ensure the quality of subsequent extrusion sheathing or wrapping processes and to prevent defects such as bubbles and reduced adhesion caused by residual moisture, the cable must be thoroughly dried after cabling.
[0003] In related technologies, the drying of the core wire insulation after extrusion and cooling, and the drying of the cable outer sheath after extrusion and cooling, often employ a blow-suction drying device for moisture removal. This involves setting up air-blowing pipes and water-suction pipes along the cable transport path. High-speed airflow from the air-blowing pipes disperses or peels away moisture from the cable surface, while a water-suction mechanism removes the moisture-containing airflow. However, in actual production, the following shortcomings exist: During cable transport, fluctuations in traction tension, radial runout of the guide rollers, and the release of internal stress generated during cable stranding inevitably cause the cable to vibrate vertically or horizontally. The positions of the air-blowing and water-suction inlets in existing blow-suction drying devices are usually fixed. When the cable vibrates and deviates from the predetermined reference position, the airflow from the air-blowing inlet cannot accurately act on the cable surface, resulting in ineffective removal of moisture from certain areas, leading to drying blind spots or uneven drying, severely affecting the final drying effect and product quality. Summary of the Invention
[0004] This application provides a blow-suction drying device for efficiently drying materials. The purpose is to enable the air outlet to compensate for the position of the cable in real time by following the cable's vibration, ensuring that the relative angle between the air outlet and the cable surface remains constant. This effectively eliminates airflow deviation and drying blind spots caused by cable positional deviations, allowing high-speed airflow to act precisely and evenly on the entire surface of the cable, thus significantly improving the efficiency of moisture removal from the cable surface and the thoroughness of drying.
[0005] This application provides a blowing and suction drying device for efficiently drying materials, which adopts the following technical solution: A blow-suction drying device for efficiently drying materials includes a frame with a feeding channel along its length. The frame has a first drying zone, a second drying zone, and a third drying zone arranged sequentially along the feeding direction of the feeding channel. The first drying zone includes a jet pump and an air inlet pipe. The jet pump has a feeding slot for cable insertion, and the feeding slot is connected to the feeding channel. One end of the air inlet pipe is connected to the jet pump, and the other end is connected to the outside air. The jet pump has multiple jet nozzles evenly spaced along its circumference, and these nozzles are connected to the feeding slot. The second drying zone includes a blowing pipe with a horizontal blowing slot inside, which is connected to the feeding channel. The third drying zone includes a suction pipe, which is connected to the feeding channel.
[0006] By adopting the above technical solution, specifically when drying the cable in the first drying zone, the jet pump draws in outside air through the air inlet pipe and sprays this air onto the surface of the cable through multiple jet nozzles. After the cable enters the jet pump through the feed trough in the feed channel, the air sprayed out through the jet nozzles completes the first drying of the cable.
[0007] After the cable is dried in the first drying zone, it is transported to the air blowing pipe through the feeding channel. The air blowing pipe blows air onto the cable through the air blowing groove, thus completing the second drying of the cable.
[0008] After the cable has been dried in the first and second drying zones, it passes through an air suction pipe to absorb any remaining moisture on the cable surface, thus completing the third drying process.
[0009] By using the first, second, and third drying zones to dry the cable multiple times, the high-speed airflow can act precisely and evenly on the entire surface of the cable, thereby significantly improving the efficiency of removing moisture from the cable surface and the thoroughness of drying.
[0010] Preferably, the jet direction of the jet nozzle is opposite to the feed direction of the cable.
[0011] By adopting the above technical solution, the reverse airflow can make more full contact with the cable surface, effectively breaking the surface tension of the water film, forcibly peeling off and blowing away the moisture. This is more effective than forward airflow in overcoming the adhesion of the water film, thereby achieving a faster drying speed and a more thorough water removal effect.
[0012] Preferably, the second drying zone is further provided with an air pump and an air supply pipe. There are two air inlet pipes. One end of the air supply pipe is connected to the air pump, and the other end of the air supply pipe is connected to the air blowing pipe.
[0013] By adopting the above technical solution, specifically when blowing air onto the cable, an air pump is used to send outside air into the air blowing pipe from the air supply pipe, and blow it onto the surface of the cable from the air blowing groove, thereby completing the air drying of the cable.
[0014] Preferably, the bottom of the air blowing pipe is provided with multiple sets of flow guiding components, which are evenly distributed at intervals along the feeding direction of the feeding channel. Each flow guiding component includes two flow guiding plates, which are movably installed at the bottom of the air blowing pipe in a vertical direction. The two flow guiding plates are distributed on the left and right sides of the air blowing groove, and the two flow guiding plates are used to adaptively adjust the air outlet direction of the air blowing groove.
[0015] By employing the above technical solution, the air outlet direction of the air blowing channel is adjusted using a guide plate, ensuring that the air outlet direction can compensate for the cable's vibration in real time. This effectively guarantees that the relative angle between the air outlet and the cable surface remains constant. Consequently, it effectively eliminates air blowing deviation and drying blind spots caused by cable positional deviations, allowing high-speed airflow to act precisely and evenly on the entire cable surface, thus significantly improving the efficiency of moisture removal and the thoroughness of drying the cable surface.
[0016] Preferably, the flow guiding assembly further includes two adjusting rollers, which are respectively installed vertically at the bottom of the two flow guiding plates. The adjusting rollers are used to drive the corresponding flow guiding plates to adjust their positions.
[0017] By adopting the above technical solution, the air outlet direction of the air blowing channel is changed by adjusting the position of the guide plate, so that the relative angle between the air outlet direction of the air blowing channel and the cable surface remains constant, thereby ensuring that the gas blown out of the air blowing channel can always act on the cable surface.
[0018] When the cable is transported within the feeding channel, two adjusting rollers are positioned on either side of the cable, providing slight restraint and effectively reducing cable vibration during transport. Simultaneously, the cable's inevitable vibrations will compress the adjusting rollers, causing them to shift and simultaneously displacing the corresponding guide plates. This adjustment of the guide plates alters the airflow direction from the blowing channel.
[0019] Preferably, the flow guiding assembly further includes two vertical support parts, each consisting of two vertical support rods. The tops of both vertical support rods are connected to the bottom of the air blowing pipe. A first rotating rod is inserted horizontally between the bottoms of the two vertical support rods. The first rotating rod is rotatably installed between the two vertical support rods. A rotating shaft is inserted vertically inside the adjusting roller. The first rotating rod passes through the rotating shaft. A transition plate is integrally connected to the side wall of the flow guiding plate horizontally. The transition plate is sleeved around the rotating shaft.
[0020] By adopting the above technical solution, when adjusting the position of the guide plate, after the cable squeezes the adjusting roller, the adjusting roller moves in the same direction through the rotating shaft and the adapter plate. This ensures that the direction of the guide plate's displacement is the same as the direction of the cable's offset, thereby ensuring that the air outlet direction of the air blowing channel can follow the cable's vibration in real time to compensate for its position, effectively ensuring that the relative angle between the air blowing port and the cable surface remains constant.
[0021] Meanwhile, by connecting the rotating shaft of the adjusting roller to the first rotating rod, the adjusting roller is rotated in the forward direction when the cable is squeezed.
[0022] Preferably, the flow guiding assembly further includes a lateral support portion, which consists of two lateral support rods. A second rotating rod is inserted horizontally between the left and right ends of the two lateral support rods, and the two second rotating rods pass through the rotating shafts of the two adjusting rollers respectively.
[0023] By adopting the above technical solution, during the displacement process, the bottom of the adjusting roller is driven to rotate synchronously by the two horizontal support rods and the two second rotating rods, thereby effectively ensuring that the upper and lower ends of the adjusting roller can always remain parallel, which helps to ensure that the adjusting roller can always keep the cable in a good limiting state.
[0024] Preferably, an air suction plate is installed horizontally inside the air suction pipe, a first air suction hole is opened at the bottom of the air suction pipe, a second air suction hole is opened on the surface of the air suction plate, the first air suction hole and the second air suction hole are kept in communication, and a plurality of air extraction pipes are connected below the air suction pipe, the air extraction pipes are kept in communication with the first air suction hole.
[0025] By adopting the above technical solution, when the cable is specifically being dried in the third drying zone, the suction pipe draws air into the suction pipe. During the suction process, the moisture remaining on the surface of the cable is drawn into the suction pipe through the second suction hole and the first suction hole, thereby completing the third drying of the cable.
[0026] Preferably, a return pipe is provided between the air extraction pipe and the air extraction pump.
[0027] By adopting the above technical solution, the air extraction pipe will simultaneously draw away the air inside the pipe while absorbing the moisture from the surface of the cable. The air drawn away by the air extraction pipe will flow back to the air pump through the return pipe, and the air pump will draw this air back into the air blowing pipe to blow air onto the cable. This allows the air in the air blowing pipe and the air extraction pipe to be recycled, which helps to improve the efficiency of drying the cable.
[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. Specifically, when drying the cable in the first drying zone, the jet pump draws in outside air through the air inlet pipe and sprays this air onto the surface of the cable through multiple jet nozzles. After the cable enters the jet pump through the feed trough in the feed channel, the air sprayed out through the jet nozzles completes the first drying of the cable.
[0029] After the cable is dried in the first drying zone, it is transported to the air blowing pipe through the feeding channel. The air blowing pipe blows air onto the cable through the air blowing groove, thus completing the second drying of the cable.
[0030] After the cable has been dried in the first and second drying zones, it passes through an air suction pipe to absorb any remaining moisture on the cable surface, thus completing the third drying process.
[0031] By using the first, second, and third drying zones to dry the cable multiple times, the high-speed airflow can act precisely and evenly on the entire surface of the cable, which in turn significantly improves the efficiency of removing moisture from the cable surface and the thoroughness of drying. 2. By using a guide plate to adjust the air outlet direction of the air blowing channel, the air outlet direction can be adjusted in real time to compensate for the vibration of the cable, thus effectively ensuring that the relative angle between the air outlet and the cable surface remains constant. This effectively eliminates air blowing deviation and drying blind spots caused by cable positional deviation, allowing high-speed airflow to act precisely and evenly on the entire surface of the cable, thereby significantly improving the efficiency of moisture removal and the thoroughness of drying the cable surface. 3. By adjusting the position of the guide plate, the air outlet direction of the air blowing channel is changed, so that the relative angle between the air outlet direction of the air blowing channel and the cable surface remains constant, thereby ensuring that the gas blown out of the air blowing channel can always act on the cable surface.
[0032] When the cable is transported within the feeding channel, two adjusting rollers are positioned on either side of the cable, providing slight restraint and effectively reducing cable vibration during transport. Simultaneously, the cable's inevitable vibrations will compress the adjusting rollers, causing them to shift and simultaneously displacing the corresponding guide plates. This adjustment of the guide plates alters the airflow direction from the blowing channel. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0036] Example: This application discloses a blowing and suction drying device for efficiently drying materials, referring to... Figure 1 and Figure 2The system includes a frame 1, with a feeding channel 2 along its length. After the cable is processed in the previous step, it is transported through the feeding channel 2 on the frame 1. Along the feeding direction of the feeding channel 2, the frame 1 is sequentially equipped with a first drying zone 3, a second drying zone 4, and a third drying zone 5. During the transport of the cable through the feeding channel 2, it passes through the first drying zone 3, the second drying zone 4, and the third drying zone 5 multiple times for drying, thereby effectively improving the final drying effect and product quality of the cable.
[0037] Reference Figure 1 and Figure 2 The first drying zone 3 is equipped with a jet pump 6 and an air inlet pipe 7. The jet pump 6 has a feed trough 8 for cable insertion, and the feed trough 8 is connected to the feed channel 2. One end of the air inlet pipe 7 is connected to the jet pump 6, and the other end of the air inlet pipe 7 is connected to the outside air. Multiple jet nozzles 9 are evenly spaced along the periphery of the jet pump 6, and the jet nozzles 9 are connected to the feed trough 8.
[0038] Specifically, when drying the cable in the first drying zone 3, the jet pump 6 draws in outside air through the air inlet pipe 7 and sprays this air onto the surface of the cable through multiple jet nozzles 9. After the cable enters the jet pump 6 through the feed trough 8 in the feed channel 2, the air sprayed out through the jet nozzles 9 completes the first drying of the cable.
[0039] Furthermore, the jet direction of the jet nozzle 9 is opposite to the feed direction of the cable.
[0040] The counter-current airflow can make more full contact with the cable surface, effectively breaking the surface tension of the water film, forcibly peeling off and blowing away the moisture. This is more effective than the forward airflow in overcoming the adhesion of the water film, thus achieving a faster drying speed and a more thorough dehydration effect.
[0041] Reference Figure 1 , Figure 2 as well as Figure 3 The second drying zone 4 includes an air blowing pipe 10, and an air blowing groove 11 is opened in the air blowing pipe 10 along the horizontal direction. The air blowing groove 11 is generally elongated and is connected to the feed channel 2.
[0042] After the cable is dried in the first drying zone 3, it is transported to the air blowing pipe 10 through the feeding channel 2. The air blowing pipe 10 blows air onto the cable through the air blowing groove 11, thereby completing the second drying of the cable.
[0043] Reference Figure 1 The third drying zone 5 includes an air suction pipe 12, which is connected to the feed channel 2. After the cable is dried in the first drying zone 3 and the second drying zone 4, the air suction pipe 12 absorbs any remaining moisture on the surface of the cable, thus completing the third drying process.
[0044] The cable is dried multiple times using the first drying zone 3, the second drying zone 4, and the third drying zone 5, so that the high-speed airflow can act precisely and evenly on the entire surface of the cable, which helps to significantly improve the efficiency of removing moisture from the cable surface and the thoroughness of drying.
[0045] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 The second drying zone 4 is also equipped with an air pump 13 and an air supply pipe 14. There are two air supply pipes 14. One end of the air supply pipe 14 is connected to the air pump 13, and the other end of the air supply pipe 14 is connected to the air blowing pipe 10. Specifically, when blowing air onto the cable, the air pump 13 sends outside air into the air blowing pipe 10 from the air supply pipe 14, and blows it onto the surface of the cable from the air blowing groove 11, thereby completing the air drying of the cable.
[0046] At the same time, refer to Figure 1 , Figure 3 as well as Figure 4 Multiple sets of flow guiding components are added to the bottom of the air blowing pipe 10, and the multiple sets of flow guiding components are evenly distributed at intervals along the feeding direction of the feeding channel 2. The flow guiding components include two flow guiding plates 15, which are movably installed at the bottom of the air blowing pipe 10 in the vertical direction, and the two flow guiding plates 15 are distributed on the left and right sides of the air blowing groove 11. The two flow guiding plates 15 are used to adaptively adjust the air outlet direction of the air blowing groove 11.
[0047] The air outlet direction of the air blowing channel 11 is adjusted by the guide plate 15, ensuring that the air outlet direction of the air blowing channel 11 can be compensated for in real time according to the vibration of the cable. This effectively ensures that the relative angle between the air outlet and the cable surface remains constant. This effectively eliminates air blowing deviation and drying blind spots caused by cable positional deviation, allowing the high-speed airflow to act precisely and evenly on the entire surface of the cable, thus significantly improving the efficiency of moisture removal and the thoroughness of drying the cable surface.
[0048] Specifically, refer to Figure 1 , Figure 3 as well as Figure 4 The airflow guiding assembly also includes two adjusting rollers 16, which are vertically mounted on the bottom of the two airflow guiding plates 15. The adjusting rollers 16 are used to drive the corresponding airflow guiding plates 15 to move, thereby adjusting the position of the airflow guiding plates 15. By adjusting the position of the airflow guiding plates 15, the air outlet direction of the air blowing channel 11 is changed, so that the relative angle between the air outlet direction of the air blowing channel 11 and the cable surface remains constant, thereby ensuring that the gas blown out of the air blowing channel 11 can always act on the cable surface.
[0049] When the cable is transported within the feeding channel 2, two adjusting rollers 16 are positioned on the left and right sides of the cable, providing slight restraint and effectively reducing the amplitude of cable vibration during transport. Simultaneously, the cable inevitably vibrates and compresses the adjusting rollers 16. This compression causes the rollers 16 to shift, which in turn moves the corresponding guide plate 15, thereby altering the airflow direction of the air blowing channel 11.
[0050] Specifically, refer to Figure 1 , Figure 3 as well as Figure 4 The flow guiding assembly also includes two vertical support sections, each composed of two vertical support rods 17. The tops of both vertical support rods 17 are connected to the bottom of the air blowing pipe 10. A first rotating rod 18 is horizontally inserted between the bottoms of the two vertical support rods 17, and is rotatably mounted between them. A rotating shaft 19 is vertically inserted inside the adjusting roller 16, and the first rotating rod 18 passes through the rotating shaft 19. A transition plate 20 is integrally connected to the side wall of the flow guiding plate 15 horizontally, and the transition plate 20 is fitted around the circumference of the rotating shaft 19.
[0051] Specifically, when adjusting the position of the guide plate 15, after the cable squeezes the adjusting roller 16, the adjusting roller 16 moves in the same direction through the rotating shaft 19 and the adapter plate 20. This ensures that the direction of the guide plate 15's displacement is the same as the direction of the cable's offset, thereby ensuring that the air outlet direction of the air blowing groove 11 can follow the cable's vibration in real time to compensate for its position, effectively ensuring that the relative angle between the air blowing port and the cable surface remains constant.
[0052] Meanwhile, by connecting the rotating shaft 19 of the adjusting roller 16 to the first rotating rod 18, the adjusting roller 16 will rotate in the forward direction when the cable is squeezed.
[0053] Specifically, refer to Figure 4 The flow guiding component also includes a lateral support section, which consists of two lateral support rods 21. A second rotating rod 22 is inserted horizontally between the left and right ends of the two lateral support rods 21. The two second rotating rods 22 pass through the rotating shafts 19 of the two adjusting rollers 16 respectively.
[0054] During the displacement process, the bottom of the adjusting roller 16 is driven to rotate synchronously by the two horizontal support rods 21 and the two second rotating rods 22, which effectively ensures that the upper and lower ends of the adjusting roller 16 can always remain parallel, thus helping to ensure that the adjusting roller 16 can always keep the cable in a good limiting state.
[0055] Specifically, refer to Figure 1 and Figure 5 An air suction plate 23 is installed horizontally inside the air suction pipe 12. A first air suction hole 24 is opened at the bottom of the air suction pipe 12, and a second air suction hole 25 is opened on the surface of the air suction plate 23. The first air suction hole 24 and the second air suction hole 25 are connected. At the same time, multiple suction pipes 26 are connected to the bottom of the air suction pipe 12, and the suction pipes 26 are connected to the first air suction hole 24.
[0056] When the cable is being dried in the third drying zone 5, the suction pipe 26 draws air into the suction pipe 12. During the suction process, the moisture remaining on the surface of the cable is drawn into the suction pipe 26 through the second suction hole 25 and the first suction hole 24, thus completing the third drying of the cable.
[0057] Furthermore, referring to Figure 1 A return pipe 27 is provided between the air extraction pipe 26 and the air extraction pump 13.
[0058] While the suction pipe 26 absorbs the moisture from the surface of the cable, it also simultaneously draws out the air from the suction pipe 12. The air drawn out by the suction pipe 26 will flow back to the suction pump 13 through the return pipe 27, and the suction pump 13 will draw this air back into the blowing pipe 10 to blow air onto the cable. This allows the air in the blowing pipe 10 and the suction pipe 12 to be recycled, which helps to improve the efficiency of drying the cable.
[0059] The implementation principle of the blowing and suction drying device for efficiently drying materials according to the embodiments of this application is as follows: The system includes a frame 1, with a feeding channel 2 extending along its length. After the cable has been processed in the previous step, it is transported through the feeding channel 2 on the frame 1. Along the feeding direction of the feeding channel 2, the frame 1 is sequentially equipped with a first drying zone 3, a second drying zone 4, and a third drying zone 5. During the transport of the cable through the feeding channel 2, it passes through the first drying zone 3, the second drying zone 4, and the third drying zone 5 multiple times for drying, thereby effectively improving the final drying effect and product quality of the cable.
[0060] The first drying zone 3 is equipped with a jet pump 6 and an air inlet pipe 7. The jet pump 6 has a feed trough 8 for cable insertion, and the feed trough 8 is connected to the feed channel 2. One end of the air inlet pipe 7 is connected to the jet pump 6, and the other end of the air inlet pipe 7 is connected to the outside air. Multiple jet nozzles 9 are evenly spaced along the periphery of the jet pump 6, and the jet nozzles 9 are connected to the feed trough 8.
[0061] Specifically, when drying the cable in the first drying zone 3, the jet pump 6 draws in outside air through the air inlet pipe 7 and sprays this air onto the surface of the cable through multiple jet nozzles 9. After the cable enters the jet pump 6 through the feed trough 8 in the feed channel 2, the air sprayed out through the jet nozzles 9 completes the first drying of the cable.
[0062] Furthermore, the jet direction of the jet nozzle 9 is opposite to the feed direction of the cable.
[0063] The counter-current airflow can make more full contact with the cable surface, effectively breaking the surface tension of the water film, forcibly peeling off and blowing away the moisture. This is more effective than the forward airflow in overcoming the adhesion of the water film, thus achieving a faster drying speed and a more thorough dehydration effect.
[0064] The second drying zone 4 includes an air blowing pipe 10, and an air blowing groove 11 is opened in the air blowing pipe 10 along the horizontal direction. The air blowing groove 11 is generally elongated and is connected to the feed channel 2.
[0065] After the cable is dried in the first drying zone 3, it is transported to the air blowing pipe 10 through the feeding channel 2. The air blowing pipe 10 blows air onto the cable through the air blowing groove 11, thereby completing the second drying of the cable.
[0066] The third drying zone 5 includes an air suction pipe 12, which is connected to the feed channel 2. After the cable has been dried in the first drying zone 3 and the second drying zone 4, the air suction pipe 12 absorbs any remaining moisture on the surface of the cable, thus completing the third drying process.
[0067] The cable is dried multiple times using the first drying zone 3, the second drying zone 4, and the third drying zone 5, so that the high-speed airflow can act precisely and evenly on the entire surface of the cable, which helps to significantly improve the efficiency of removing moisture from the cable surface and the thoroughness of drying.
[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
