Description

Technical Field

[0001] The present application relates to the field of weaving equipment, and in particular to an air supply device and an air spinning machine. Background Art

[0002] The air-spinning machine is a device that uses high-speed airflow to stretch fibers into long and thin fibers, which are then spun into yarns in a high-speed rotating conical container. It processes fibers by compressing and heating compressed air during the production process.

[0003] Therefore, the air spinning machine needs an air compressor to supply air to the air spinning machine. Since there are more impurities in the air in the factory area and the humidity in the air in the factory in the south is higher, it is necessary to install a purification and filtering device in the air supply pipeline of the air compressor to the air spinning machine to control the oil content, water content and dust content in the compressed air. However, due to the existence of the purification and filtering device, there is a large pressure loss in the compressed air.

[0004] A common solution in factories is to install larger air compressors with stronger compression capabilities to supply air. However, due to limited space, the size of the air compressor is also limited, so there is still a problem of insufficient pressure supply to the air-spinning machine. Summary of the invention

[0005] In order to solve the problem that the air purification step of the conventional air-jet spinning machine causes excessive pressure loss of compressed air after the air compression step, the present application provides an air supply device and an air-jet spinning machine.

[0007] Through the above technical solution, before the air enters the air compressor, it first passes through the dust removal chamber, oil removal chamber and drying chamber to remove dust, water and oil in the air, so that the air entering the air compressor is relatively clean. Then, the compressed air output after being compressed by the air compressor only needs simple purification or even no purification before use, which greatly reduces the pressure loss generated in the process of transporting the output compressed air to the air spinning machine, so that the pressure of the compressed air obtained by the air spinning machine is more sufficient and stable.

[0018] To summarize, the present application purifies the air entering the air compressor in advance by setting up a dust removal chamber, a drying chamber and an oil removal chamber, so that the compressed air output by the air compressor only needs simple purification or no purification before use, which greatly reduces the pressure lost in the process of transporting the compressed air output by the air compressor to the air spinning machine. At the same time, since the third pipe that needs to be heated is located above the second pipe that needs to be cooled, the air between the third pipe and the second pipe is not easy to circulate with each other, resulting in the air in the third pipe being contaminated.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-10 This application is described in further detail.

[0032] The embodiments of the present application disclose an air supply device and an air spinning machine.

[0033] First, refer to Figure 1 The embodiment of the present application discloses an air supply device including a frame 1, which is fixedly mounted on the ground. An air compressor 11 is fixedly mounted on the frame 1, and an air intake chamber 2 is also arranged on the mounting frame. The air intake chamber 2 includes a dust removal chamber 3, an oil removal chamber 5 and a drying chamber 4. The air is purified by the dust removal chamber 3, the oil removal chamber 5 and the drying chamber 4 and then input into the air compressor 11 for compression, so that the compressed air output by the air compressor 11 can be directly used by the air-jet spinning machine without further purification, thereby greatly reducing the pressure loss during the transportation of the compressed air.

[0034] Reference Figure 1 The dust removal chamber 3 includes a first pipe 31 fixedly mounted on the frame 1. The first pipe 31 is vertical, the lower end of the first pipe 31 is closed, the air inlet end of the first pipe 31 is the upper end and is horizontal, and an air intake fan 12 is fixedly mounted in the air inlet end of the first pipe 31 for air supply. A horizontal filter water tank 32 is fixedly mounted on the frame 1, and the filter water tank 32 contains clean water for filtration. A connecting valve 33 and a drain valve 37 are fixedly mounted on the bottom wall of the filter water tank 32, and the lower end of the first pipe 31 is fixedly connected to the connecting valve 33 through a pipe.

[0035] Reference Figure 1 and Figure 2 A plurality of mutually parallel jet pipes 36 are fixedly installed on the bottom wall of the filtered water tank 32. The jet pipes 36 are laid on the bottom wall of the filtered water tank 32 to form a jet pipe 36 network. The jet pipes 36 are horizontal, and a plurality of air outlet holes 361 are evenly spaced along the length direction of the jet pipes 36 on the side walls.

[0036] Reference Figure 2 A plurality of vertical cutting strips 35 are fixedly installed in the filtered water tank 32. The cutting strips 35 are distributed in a network shape, and the lower side of the cutting strips 35 is in a blade shape.

[0037] After the connecting valve 33 is opened, the air in the first pipe 31 enters the air jet pipe 36 through the connecting valve 33, and then is ejected from the air outlet 361. The smaller bubbles ejected from the air outlet 361 are cut by the cutting strip 35 to form smaller bubbles. After fully contacting with the clean water, the dust in the air and some impurities dissolved in the water are filtered out from the water. A filter screen is also provided on the inner top wall of the filtered water tank 32 to filter the remaining fine dust in the air.

[0038] Reference Figure 1The drying chamber 4 includes a second pipe 41, both ends of the second pipe 41 are closed, and the second pipe 41 is fixedly mounted on the frame 1 and located above the filtered water tank 32. Reference Figure 1 and Figure 2 The top wall of the filtered water tank 32 is fixedly connected to the lower end of the second pipe 41 through the first air outlet pipe 321, and the air in the filtered water tank 32 enters the second pipe 41 through the first air outlet pipe.

[0039] Reference Figure 2 The diameter of the first air outlet pipe 321 is smaller than the diameter of the second pipe 41. A water inlet valve 38 is fixedly installed on the side wall of the first air outlet pipe 321. The water in the filtered water tank 32 is replaced through the cooperation between the drain valve 37 and the water inlet valve 38, and the water from the water inlet valve 38 will backwash the main filtering part of the filter when passing through the filter.

[0040] Reference Figure 1 and Figure 3 A condensation mechanism 6 is arranged in the second pipe 41, and the condensation mechanism 6 includes a plurality of condensation tubes 61. The condensation tubes 61 are staggered in the second pipe 41 along the vertical direction, and the condensation tubes 61 are horizontal. The two ends of the condensation tubes 61 are respectively fixedly connected to the liquid outlet and the liquid inlet of the condenser.

[0041] Reference Figure 3 A drying mesh bag 62 is arranged on the condenser tube 61 , and the drying mesh bag 62 is filled with a desiccant. After the moisture in the air is condensed into liquid through the condenser tube 61 , it is absorbed by the desiccant in the drying mesh bag 62 .

[0042] Reference Figure 3 and Figure 5 One end of the condenser tube 61 passes through the side wall of the second pipe 41 and is fixedly and sealedly connected to the side wall of the second pipe 41. A mounting block 411 is welded on the side wall of the second pipe 41 at the other end of the condenser tube 61. A rectangular replacement port 412 is formed through the mounting block 411. The other end of the condenser tube 61 passes through the replacement port 412. The drying mesh bag 62 includes a mesh bag body 621 and a bracket. The bracket includes two mounting rings 622. The mounting ring 622 is slidably mounted on the condenser tube 61. The condenser tube 61 passes through the mesh bag body 621. The mounting ring 622 is located in the two perforations of the mesh bag body 621 and is fixedly connected to the mesh bag body 621. The mounting ring 622 closes the two perforations. The desiccant is filled in the mesh bag body 621.

[0043] Reference Figure 3 and Figure 5The mesh bag body 621 is provided with a fixing member 7, which includes an arc-shaped spring sheet 71 and two support rods 72. The opening of the mesh bag body 621 faces upward. In the first solution of the present application, the two support rods 72 are respectively fixedly installed on both sides of the bag opening of the mesh bag body 621, and the support rods 72 are parallel to the condenser tube 61. The arc-shaped spring sheet 71 is installed on one end of the mesh bag body 621 facing the replacement port 412, and the axis of the arc-shaped spring sheet 71 is parallel to the support rod 72.

[0044] Reference Figure 3 and Figure 5 The opening of the arc spring piece 71 faces upward, and the two ends of the arc spring piece 71 are fixedly connected to the two support rods 72 respectively. When one end of the arc spring piece 71 is pressed against the other end, the arc spring piece 71 drives the two support rods 72 to close the bag opening of the net bag body 621.

[0045] Reference Figure 3 and Figure 5 The fixing member 7 includes a fixing block 73 slidably mounted in the replacement port 412. A mounting hole 731 is provided in the middle of the fixing block 73. The condenser tube 61 coaxially passes through the mounting hole 731. Two support rods 72 cross each other at one end facing the fixing block 73. The ends of the two support rods 72 that cross each other are staggered up and down. A limiting groove 732 is provided on the side wall of the fixing block 73. The ends of the two support rods 72 that cross each other are located in the limiting groove 732.

[0046] Reference Fig.10 In another embodiment of the present application, the connection between the intersecting ends of the support rods 72 and the parallel ends of the support rods 72 is bent, and the distance between the parallel ends of the support rods 72 is smaller than the distance between the intersecting ends of the support rods 72 and the connection ends of the intersecting ends of the support rods 72.

[0047] The support rods 72 are designed in the first solution, which can only close the opening of the net bag body 621 but not completely close it. However, the capacity of the desiccant in the net bag is relatively large, and there is a certain redundancy after the net bag is compressed, which is suitable for rod-shaped desiccant, so that the desiccant is not easily crushed. In the second solution, the support rods 72 can press against each other to completely close the opening of the net bag body 621, which is suitable for granular desiccant that is easy to spill out. The completely closed opening of the net bag body 621 makes it difficult for the desiccant in the net bag body 621 to spill out.

[0048] Reference Figure 3 and Figure 6 A limiting block 733 is detachably provided in the limiting groove 732 by means of bolts. Two guide holes 7331 are formed through the limiting block 733 . The two support rods 72 slide through the two guide holes 7331 , respectively.

[0049] Reference Figure 6 and Figure 7 The cross-section of one end of the support rod 72 that is bent and crossed is square, and a plurality of balls 7332 are rotatably installed on the inner wall of the guide hole 7331 along the axial direction of the guide hole 7331. Guide grooves 721 are opened on the four side walls of the intersection section of the support rod 72 along the length direction of the support rod 72, and the balls 7332 are rollingly installed in the guide grooves 721.

[0050] Reference Figure 3 , Figure 6 and Figure 7 After the fixing block 73 is completely slid and pushed into the replacement port 412, the limit block 733 pushes the cross ends of the two support rods 72 to slide toward each other, thereby driving the parallel ends of the two support rods 72 to move closer to each other until they are pressed against each other to close the bag opening of the net bag body 621. Due to the support of the ball bearing 7332, the support rod 72 is not easy to get stuck during the sliding process.

[0051] Reference Figure 3 and Figure 8 The fixing member 7 also includes a circular baffle 74 coaxially slidably installed on the condenser tube 61, the mesh bag body 621 is located between the baffle 74 and the mounting block 411, a connecting ring 741 is coaxially and integrally provided on the side of the baffle 74 facing the mesh bag, an annular groove 7411 is coaxially provided on the inner wall of the connecting ring 741, a circular connecting plate 75 is coaxially fixedly installed on the end of the support rod 72 facing the baffle 74, the plate surface of the connecting plate 75 is flush with the end surface of the support rod 72, and the support rod 72 under normal conditions pushes the two connecting plates 75 to fit in the annular groove 7411.

[0052] Reference Figure 3 and Figure 8 When the limit block 733 pushes the support rod 72 to slide, one end of the support rod 72 is pressed against the baffle 74 through the connecting plate 75, so that the support rod 72 will not damage the inner wall of the second pipe 41 when sliding. Moreover, since the baffle 74 is a flat plate, compared with the support rod 72 sliding on the curved inner wall of the second pipe 41, the support rod 72 is not prone to end jamming when sliding.

[0053] Reference Figure 3 and Figure 5 When the net bag body 621 is pulled out of the second pipe 41, the baffle 74 closes the replacement port 412. Since the air pressure inside the second pipe 41 is greater than the external air pressure during the air supply process, the baffle 74 will press against the side wall of the mounting block 411 under the action of the air pressure to close the replacement port 412. The gap between the baffle 74 and the condenser tube 61 will leak cold air due to the high pressure in the second pipe 41, making it difficult for external air to enter the second pipe 41 and pollute the air in the second pipe 41.

[0054] Reference Figure 3 and Figure 5 The side wall of the second pipe 41 is provided with a sealing mechanism 8, which includes a sealing tube 81, a sealing plate 82 and a sealing ring 83. The sealing ring 83 is fixedly mounted on the side wall of the mounting block 411 and encloses the replacement port 412. The sealing tube 81 is coaxially slidably mounted on the condenser tube 61. An external thread 9 is integrally arranged on a section of the side wall of the condenser tube 61 located in the replacement port 412. An internal thread 10 matching the external thread 9 is integrally arranged on the inner wall of the sealing tube 81. The sealing tube 81 is slidably mounted in the mounting hole 731, and the sealing tube 81 is threadedly sealed with the condenser tube 61.

[0055] Reference Figure 3 and Figure 5 The sealing plate 82 is circular and coaxially and integrally arranged on one end of the sealing tube 81. A connecting tube 821 is coaxially and integrally arranged on the plate surface of the sealing plate 82. An annular connecting groove 413 is coaxially opened on the side wall of the mounting block 411. An internal thread 10 is also integrally arranged on the inner wall of the connecting groove 413. An external thread 9 is integrally arranged on the outer wall of the connecting tube 821. When the sealing tube 81 is threadedly installed on the condenser tube 61, the connecting tube 821 is also threadedly installed in the connecting groove 413, and at this time, the sealing plate 82 is tightly fitted against the sealing ring 83. A seal is formed between the sealing tube 81 and the fixed block 73 through the cooperation between the sealing plate 82 and the sealing ring 83. At the same time, the pressure of the limit block 733 on the support rod 72 is provided by the cooperation between the connecting tube 821 and the connecting groove 413. Compared with the pressure provided purely by the cooperation between the sealing tube 81 and the condenser 61, the sealed connection between the condenser 61 and the second pipe 41 is less likely to be damaged.

[0056] Reference Figure 3 and Figure 4 The sealing mechanism 8 also includes an organ pipe 84, on both ends of which are fixedly mounted a first annular fixing plate 841 and a second annular fixing plate 842, respectively. The first fixing plate 841 is fixedly mounted on the end surface of the mounting block 411, and the organ pipe 84 is sleeved outside the mesh bag body 621 and the sealing plate 82. A horizontal sliding rod 85 is fixedly mounted on the mounting block 411, and the sliding rod 85 slides through the first fixing plate 841 and the second fixing plate 842 in sequence.

[0057] Reference Figure 3 , Figure 4 and Figure 5, an internal thread 10 is provided in the inner hole of the second fixing plate 842, and an external thread 9 matching therewith is provided on the side wall of the sealing plate 82. The sealing plate 82 is unscrewed from the mounting block 411, and then the fixing block 73 is pulled out from the replacement port 412 to a certain distance, and the sealing plate 82 abuts against the second fixing plate 842. At this time, the sealing plate 82 is rotated so that the sealing plate 82 is threadedly installed in the inner hole of the second fixing plate 842, and then the mesh bag body 621 is pulled out. During the pulling process of the mesh bag body 621, the organ pipe 84, the second fixing plate 842 and the sealing plate 82 still form a seal on the replacement port 412, so that before the baffle 74 abuts against the mounting block 411 to form a closure on the replacement port 412, it is not easy for outside air to enter the second pipe 41 from the replacement port 412 to pollute the air in the second pipe 41.

[0058] Reference Figure 4 When the baffle plate 74 slides to the mounting block 411, the sealing plate 82 is rotated to unscrew the sealing plate 82 from the second fixing plate 842, and the second fixing plate 842 is pushed to slide toward the first fixing plate 841. After the organ pipe 84 is folded, the desiccant in the mesh bag body 621 can be replaced.

[0059] Reference Figure 4 A handle is fixedly mounted on the sealing plate 82 to facilitate the rotation of the sealing plate 82 .

[0060] Reference Figure 1 The lower end of the third pipeline 51 is fixedly connected to the upper end of the second pipeline 41 through the second outlet pipe 414. The second outlet pipe 414 is serpentine and has a diameter smaller than the third pipeline 51. The air dried in the second pipeline 41 enters the third pipeline 51 through the second outlet pipe 414 and is heated. Then, the oil in the air is decomposed and outputted under the action of the oil catalyst in the third pipeline 51.

[0061] Reference Figure 1 and Fig. 9 An air supply pipe 52 is fixedly installed at the upper end of the third pipe 51, and a cold water tank 13 and an air storage bin 14 are fixedly installed on the frame 1. The cold water tank 13 contains cold water, and the air supply pipe 52 is bent in a serpentine shape and passes through the cold water tank 13 and is fixedly connected to the air storage bin 14. A desiccant layer is laid on the inner wall of the air storage bin 14, and the hot air in the third pipe 51 is cooled by the cold water tank 13 and then transported to the air storage bin 14 for compression and temporary storage.

[0062] Reference Figure 1The air storage bin 14 is fixedly connected to the air inlet end of the air compressor 11 through a pipeline. The air storage bin 14 is used to ensure sufficient air supply to the air inlet end of the air compressor 11. Since the oil in the air decomposes to produce water, the water in the air cooled by the cold water tank 13 will liquefy and then be absorbed by the desiccant layer in the air storage bin 14 to further purify the air.

[0063] Reference Figure 1 A first water pipe 131 and a second water pipe 132 are fixedly installed on the cold water tank 13. The first water pipe 131 is connected to a water source, and the second water pipe 132 is used to output hot water.

[0064] Reference Figure 1 Insulation layers 15 are laid on the side walls of the second pipe 41 and the third pipe 51 for heat preservation.

[0065] The implementation principle of an air supply device in an embodiment of the present application is as follows: after the air is filtered by the filter water tank 32, it is condensed and dried and then heated to catalytically oxidize the oil, and then the clean air is temporarily stored in the air storage bin 14 and supplied to the air compressor 11 for use.

[0066] When the air is condensed in the second pipe 41, the liquid water produced by the condensation will be promptly absorbed by the desiccant on the condenser tube 61. When the desiccant needs to be replaced, loosen the sealing tube 81 and the sealing plate 82, separate the sealing tube 81 and the sealing plate 82 from the fixing block 73, and then slide the fixing block 73 out of the replacement port 412. When the fixing block 73 slides to the sealing plate 82 and abuts against the second fixing plate 842, rotate the sealing plate 82 until the sealing plate 82 and the second fixing plate 842 are threadedly connected, and then continue to pull the sealing plate 82 by the handle to slide the fixing block 73, the support rod 72 and the mesh bag body 621 out of the replacement port 412. Then, after separating the connecting plate 75 from the connecting ring 741, pull out the mesh bag body 621, and then rotate the mesh bag body 621 to pour out the expired desiccant and put in a new desiccant, and then install the mesh bag body 621 by reversing the above operation.

[0067] In a second aspect, an embodiment of the present application discloses an air-jet spinning machine, comprising a spinning machine body, which is supplied with air by the above-mentioned air supply device.
