Description

Technical Field

[0001] This application relates to the field of weaving equipment, and particularly to an air supply device and an air-jet spinning machine. Background Art

[0002] An air-jet spinning machine is a device that uses high-speed air flow to stretch fibers into slender fibers and then spins them into yarns in a conical container rotating at high speed. It processes fibers by compressing and heating them with compressed air during the production process.

[0003] Therefore, an air compressor is required to supply air to the air-jet spinning machine. Since there are more impurities in the air in the factory area and the humidity in the air in factories in the south is relatively high, a purification and filtration device needs to be installed in the air supply pipeline of the air compressor to the air-jet spinning machine to control the oil content, water content, and dust content in the compressed air. However, due to the presence of the purification and filtration device, there is a relatively large pressure loss in the compressed air.

[0004] A common solution in the factory is to install a larger air compressor with stronger compression capacity to supply air. However, limited by the site, the volume of the air compressor also has a limit. Therefore, there will still be a problem of insufficient air supply pressure for the air-jet spinning machine. Summary of the Invention

[0005] To solve the problem that the traditional air purification step for the air-jet spinning machine after the air compression step results in too large a pressure loss of the compressed air, this application provides an air supply device and an air-jet spinning machine.

The intake chamber includes a dust removal chamber, an oil removal chamber, and a drying chamber. The dust removal chamber, the oil removal chamber, and the drying chamber are connected to each other. An intake fan is installed at the intake end of the intake chamber.

[0008] Through the above technical solution, before the air enters the air compressor, it first passes through the dust removal chamber, the oil removal chamber, and the drying chamber to remove dust, water, and oil in the air, making the air entering the air compressor relatively clean. Then, the compressed air output after being compressed by the air compressor only needs to be simply purified or even does not need to be purified to be used, greatly reducing the pressure loss generated during the process of transporting the output compressed air to the air-jet spinning machine, and making the pressure of the compressed air obtained by the air-jet spinning machine more sufficient and stable.

[0014] Optionally, the drying net bag includes a net bag body and a bracket, the bracket includes two mounting rings, the mounting rings are slidably mounted on the condensing pipe, the net bag body is located between the two mounting rings and is connected to the mounting rings, the condensing pipe is horizontal, the bag mouth of the net bag body faces upward, the drying agent is filled in the net bag body, a fixing member is further arranged on the net bag body for closing the bag mouth of the net bag body, a replacement opening is opened on the side wall of the second pipe, the replacement opening is used for extracting the net bag body to replace the drying agent, and a sealing mechanism is further arranged on the side wall of the second pipe for sealing the replacement opening.

[0015] Optionally, the diameter of the first air outlet pipe is smaller than that of the second pipe. The air outlet end of the second pipe is connected to the air inlet end of the third pipe through a second air outlet pipe, and the diameter of the second air outlet pipe is smaller than that of the third pipe.

[0016] Through the above technical solution, when the air enters the second pipe from the first air outlet pipe, the flow rate will be significantly slowed down to facilitate sufficient cooling and drying. Similarly, when the air enters the third pipe from the second air outlet pipe, the flow rate will also be significantly reduced to facilitate sufficient catalytic oxidation of the oil in the air.

[0020] To sum up, the present application pre-purifies the air entering the air compressor 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 to be used, greatly reducing the pressure loss of the compressed air output by the air compressor during the process of being transported to the rotor 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 polluted.

Detailed implementation manners

[0033] The following is combined with the attached Figure 1-10This application is described in further detail.

[0034] The embodiments of the present application disclose an air supply device and an air spinning machine.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Reference Figure 1, the drying chamber 4 includes a second pipe 41 with both ends closed. The second pipe 41 is fixedly installed on the frame 1 and is located above the filtering water tank 32.

[0041] Refer to Figure 1 and Figure 2 , the top wall of the filtering water tank 32 is fixedly connected to the lower end of the second pipe 41 through a first air outlet pipe 321. The air in the filtering water tank 32 enters the second pipe 41 through the first air outlet pipe.

[0042] Refer to Figure 2 , the diameter of the first air outlet pipe 321 is smaller than that 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 filtering water tank 32 is replaced through the mutual cooperation between the drain valve 37 and the water inlet valve 38, and the water passing through the filter screen of the water inlet valve 38 will backwash the main filtering part of the filter screen.

[0043] Refer to Figure 1 and Figure 3 , a condensation mechanism 6 is arranged in the second pipe 41. The condensation mechanism 6 includes a plurality of condensation pipes 61 which are arranged vertically and staggered in the second pipe 41. The condensation pipes 61 are horizontal, and both ends of the condensation pipes 61 are fixedly connected to the liquid outlet end and the liquid inlet end of the condenser respectively.

[0044] Refer to Figure 3 , a drying mesh bag 62 is arranged on the condensation pipe 61. The drying mesh bag 62 is filled with a desiccant. After the moisture in the air is condensed and solidified into a liquid state through the condensation pipe 61, it is absorbed by the desiccant in the drying mesh bag 62.

[0045] Refer to Figure 3 and Figure 5 , one end of the condensation pipe 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. An installation block 411 is welded on the side wall of the second pipe 41 at the other end of the condensation pipe 61. A rectangular replacement opening 412 is penetrated through the installation block 411, and the other end of the condensation pipe 61 passes through the replacement opening 412. The drying mesh bag 62 includes a mesh bag body 621 and a bracket. The bracket includes two mounting rings 622 which are slidably mounted on the condensation pipe 61. The condensation pipe 61 passes through the mesh bag body 621. The mounting rings 622 are located in two through holes of the mesh bag body 621 and are fixedly connected to the mesh bag body 621. The mounting rings 622 close the two through holes, and the desiccant is filled in the mesh bag body 621.

[0046] Refer to Figure 3 and Figure 5, a fixing member 7 is provided on the mesh bag body 621. The fixing member 7 includes an arc-shaped spring piece 71 and two support rods 72. The opening of the mesh bag body 621 faces upward. In the first solution of this application, the two support rods 72 are respectively fixedly installed on both sides of the bag mouth of the mesh bag body 621, and the support rods 72 are parallel to the condensing pipe 61. The arc-shaped spring piece 71 is installed at one end of the mesh bag body 621 facing the replacement port 412, and the axis of the arc-shaped spring piece 71 is parallel to the support rods 72.

[0047] Refer to Figure 3 and Figure 5 , the opening of the arc-shaped spring piece 71 faces upward, and both ends of the arc-shaped spring piece 71 are respectively fixedly connected to the two support rods 72. When one end of the arc-shaped spring piece 71 is pressed against the other end, the arc-shaped spring piece 71 drives the two support rods 72 to close the bag mouth of the mesh bag body 621.

[0048] Refer to Figure 3 and Figure 5 , the fixing member 7 includes a fixing block 73 slidably installed in the replacement port 412. A mounting hole 731 is opened in the middle of the fixing block 73, and the condensing pipe 61 coaxially passes through the mounting hole 731. One ends of the two support rods 72 facing the fixing block 73 cross each other, and the crossed ends of the two support rods 72 are staggered up and down. A limiting groove 732 is opened on the side wall of the fixing block 73, and the crossed ends of the two support rods 72 are located in the limiting groove 732.

[0049] Refer to Figure 10 , in another solution of this application, the connection between the crossed 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 less than the distance between the connection ends of the crossed ends of the support rods 72.

[0050] The support rods 72 are designed in the first solution and can only close the bag mouth of the mesh bag body 621 but cannot be completely closed. However, the capacity of the desiccant in the mesh bag is large, and there is a certain redundancy after the mesh bag is pressed. It is suitable for rod-shaped desiccants, so that the desiccant is not easily crushed. In the second solution, the support rods 72 can be tightly pressed against each other to completely close the bag mouth of the mesh bag body 621. It is suitable for granular desiccants that are easy to spill. The completely closed bag mouth of the mesh bag body 621 makes the desiccant in the mesh bag body 621 not easy to spill.

[0051] Refer to Figure 3 and Figure 6 , a limiting block 733 is detachably installed in the limiting groove 732 through a bolt. Two guiding holes 7331 are penetrated through the limiting block 733, and the two support rods 72 respectively slide through the two guiding holes 7331.

[0052] Refer toFigure 6 and Figure 7 One end of the support rods 72 that are bent and crossed with each other has a square cross-section. 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 formed on four side walls of the crossed section of the support rods 72 along the length direction of the support rods 72. The balls 7332 are installed in the guide grooves 721 in a rolling fit.

[0053] Referring to Figure 3 、 Figure 6 and Figure 7 After completely sliding the fixing block 73 into the replacement opening 412, the limiting block 733 pushes the crossed ends of the two support rods 72 to slide towards each other, thereby driving the parallel ends of the two support rods 72 to approach each other until they are tightly abutted to close the bag mouth of the mesh bag body 621. Due to the support of the balls 7332, the support rods 72 are not likely to get stuck during the sliding process.

[0054] Referring to Figure 3 and Figure 8 The fixing member 7 further includes a circular baffle 74 coaxially and slidably installed on the condensation pipe 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 surface of the baffle 74 facing the mesh bag. An annular groove 7411 is coaxially formed on the inner wall of the connecting ring 741. A circular connecting plate 75 is coaxially and fixedly installed at one 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. Under normal conditions, the support rod 72 pushes the two connecting plates 75 to be fitted and clamped in the annular groove 7411.

[0055] Referring to Figure 3 and Figure 8 When the limiting block 733 pushes the support rod 72 to slide, one end of the support rod 72 abuts against the baffle 74 through the connecting plate 75, so that the support rod 72 will not cause damage to the inner wall of the second pipe 41 during sliding. And since the baffle 74 is a flat plate, compared with the support rod 72 sliding on the arc-shaped inner wall of the second pipe 41, the support rod 72 is not likely to get stuck at the end during sliding.

[0056] Referring to Figure 3 and Figure 5 When the mesh bag body 621 is drawn out from the second pipe 41, the baffle 74 closes the replacement opening 412. Since the air pressure inside the second pipe 41 is greater than the outside air pressure during the air supply process, the baffle 74 will abut against the side wall of the mounting block 411 under the action of the air pressure to close the replacement opening 412. The gap between the baffle 74 and the condensation pipe 61 will leak cold air due to the high pressure inside the second pipe 41, making it difficult for the outside air to enter the second pipe 41 to pollute the air inside the second pipe 41.

[0057] Reference Figure 3 and Figure 5 On the side wall of the second pipeline 41, a sealing mechanism 8 is provided. The sealing mechanism 8 includes a sealing pipe 81, a sealing plate 82 and a sealing ring 83. The sealing ring 83 is fixedly installed on the side wall of the mounting block 411 and encloses the replacement opening 412. The sealing pipe 81 is coaxially and slidably installed on the condensation pipe 61. An external thread 9 is integrally provided on a section of the side wall of the condensation pipe 61 located in the replacement opening 412. An internal thread 10 that mates with the external thread 9 is integrally provided on the inner wall of the sealing pipe 81. The sealing pipe 81 is slidably installed in the mounting hole 731, and the sealing pipe 81 is threadedly and sealingly connected to the condensation pipe 61.

[0058] Reference Figure 3 and Figure 5 The sealing plate 82 is circular. The sealing plate 82 is coaxially and integrally provided at one end of the sealing pipe 81. A connecting pipe 821 is coaxially and integrally provided on the plate surface of the sealing plate 82. A circular connecting groove 413 is coaxially provided on the side wall of the mounting block 411. An internal thread 10 is also integrally provided on the inner wall of the connecting groove 413. An external thread 9 is integrally provided on the outer side wall of the connecting pipe 821. When the sealing pipe 81 is threadedly installed on the condensation pipe 61, the connecting pipe 821 is also threadedly installed in the connecting groove 413, and at this time the sealing plate 82 fits tightly against the sealing ring 83.

[0059] Sealing is formed between the sealing pipe 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 limiting block 733 on the support rod 72 is provided through the cooperation between the connecting pipe 821 and the connecting groove 413. Compared with providing pressure solely by the cooperation between the sealing pipe 81 and the condensation pipe 61, the sealed connection between the condensation pipe 61 and the second pipeline 41 is less likely to be damaged.

[0060] Reference Figure 3 and Figure 4 The sealing mechanism 8 further includes a bellows pipe 84. Annular first fixing plates 841 and second fixing plates 842 are respectively fixedly installed at both ends of the bellows pipe 84. The first fixing plate 841 is fixedly installed on the end face of the mounting block 411. The bellows pipe 84 is sleeved outside the mesh bag body 621 and the sealing plate 82. A horizontal sliding rod 85 is fixedly installed on the mounting block 411. The sliding rod 85 sequentially slides through the first fixing plate 841 and the second fixing plate 842.

[0061] 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 that mates with it is provided on the side wall of the sealing plate 82. The sealing plate 82 is screwed out from the mounting block 411, and then when the fixing block 73 is pulled out from the replacement opening 412 to a certain distance, 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. Then, the mesh bag body 621 is continuously pulled out. Since the bellows tube 84, the second fixing plate 842, and the sealing plate 82 still form a seal at the replacement opening 412 during the pulling process of the mesh bag body 621, before the baffle 74 abuts tightly against the mounting block 411 to close the replacement opening 412, external air is not likely to enter the second duct 41 through the replacement opening 412 to contaminate the air in the second duct 41.

[0062] Refer to Figure 4 , when it slides until the baffle 74 abuts tightly against the mounting block 411, then the sealing plate 82 is continuously rotated to screw out the sealing plate 82 from the second fixing plate 842, and the second fixing plate 842 is pushed to slide towards the first fixing plate 841. After the bellows tube 84 is folded, the desiccant in the mesh bag body 621 can be replaced continuously.

[0063] Refer to Figure 4 , a handle is fixedly installed on the sealing plate 82 to facilitate the rotation of the sealing plate 82.

[0064] Refer to Figure 1 , the lower end of the third duct 51 is fixedly connected to the upper end of the second duct 41 through a second air outlet pipe 414. The second air outlet pipe 414 is serpentinely bent, and the diameter of the second air outlet pipe 414 is smaller than that of the third duct 51. The air dried in the second duct 41 enters the third duct 51 through the second air outlet pipe 414, is heated, and then the oil in the air is decomposed under the action of the oil catalyst in the third duct 51 and then output.

[0065] Refer to Figure 1 and Figure 9 , a supply pipe 52 is fixedly installed at the upper end of the third duct 51. A cold water tank 13 and a gas storage bin 14 are fixedly installed on the frame 1. The cold water tank 13 contains cold water. The supply pipe 52 is serpentinely bent and passes through the cold water tank 13 and then is fixedly connected to the gas storage bin 14. A desiccant layer is laid on the inner wall of the gas storage bin 14. The hot air in the third duct 51 is cooled by the cold water tank 13 and then transported to the gas storage bin 14 for compression and temporary storage.

[0066] Refer to 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.
