DETAILED DESCRIPTION

[0056] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0057] like Figures 1 to 13 As shown, a PTFE-based superconducting water polypropylene filament production device in one embodiment of the present invention includes a shell 1, a plurality of first conveying rollers 2, an air intake mechanism 3 and a gas processing mechanism 5.

[0058] A pair of first partitions 101 are installed in the shell 1, and a high-temperature cavity, a low-temperature cavity and a buffer cavity are formed between the pair of first partitions 101 and the inner wall of the shell 1. The filament moves through the high-temperature cavity, the low-temperature cavity and the buffer cavity in sequence.

[0059] In addition, a flow slot 102 is provided through the first partition plate 101 , and the filaments in the high-temperature chamber enter the low-temperature chamber through the flow slot 102 , and then enter the buffer chamber through the flow slot 102 .

[0060] Specifically, a pair of side walls of the outer shell 1 are respectively provided with a feed port 103 and a discharge port 104, the feed port 103 is connected with the high-temperature chamber, and the discharge port 104 is connected with the buffer chamber. The filaments sprayed from the spinning nozzle of the spinning machine pass through the feed port 103 and enter the outer shell 1 for cooling. The cooled filaments are discharged through the discharge port 104, and after winding, coating and processing, they can become polypropylene filament products.

[0061] like Figures 4 to 10 As shown, a connecting pipe 105 is fixedly connected to the first baffle plate 101 at the lower side, one end of the connecting pipe 105 located in the low-temperature chamber is connected to a first gas collecting hood 106, and one end of the connecting pipe 105 located in the buffer chamber is connected to a gas distribution member 107, and a plurality of evenly distributed gas injection holes 108 are provided on the gas distribution member 107. As the gas in the low-temperature chamber gradually increases, part of the gas in the low-temperature chamber can enter the gas distribution member 107 through the first gas collecting hood 106 and the connecting pipe 105, and then be discharged to the buffer chamber through a plurality of gas injection holes 108, so as to cool down the filaments moving in the buffer chamber again to ensure the cooling effect of the filaments.

[0062] like Figures 1 to 10 As shown, a plurality of first conveying rollers 2 are rotatably connected to the high temperature chamber and the low temperature chamber respectively, and a plurality of second conveying rollers 201 are rotatably connected to the buffer chamber. The first conveying rollers 2 and the second conveying rollers 201 are both used to convey the filaments, so that the filaments can pass through the high temperature chamber, the low temperature chamber and the buffer chamber in sequence to achieve cooling of the filaments.

[0063] Preferably, the first conveying roller 2 and the second conveying roller 201 are both connected by a belt to ensure the movement of the filaments.

[0064] The first conveying roller 2 is hollow inside, and is provided with a number of evenly distributed cooling holes 202. A hollow tube 203 is connected to the first conveying roller 2, and the hollow tube 203 is rotatably connected to the outer shell 1. A pair of gas distribution covers 204 are connected to the side wall of the outer shell 1, and the pair of gas distribution covers 204 correspond to the high-temperature cavity and the low-temperature cavity respectively, and the gas distribution covers 204 cover the outside of the hollow tube 203. The gas in the gas distribution cover 204 can enter the first conveying roller 2 through the hollow tube 203, and then be discharged through the number of cooling holes 202. Since the filaments bypass the first conveying roller 2, the gas discharged from the first conveying roller 2 can directly act on the filaments, so as to improve the cooling efficiency of the filaments, and also ensure the uniformity of the cooling of the filaments.

[0065] In addition, a return pipe 205 is connected to the housing 1, and the low-temperature chamber is connected to the air inlet end of the first air pump 301 through the return pipe 205. Part of the gas in the low-temperature chamber can be re-absorbed by the first air pump 301 through the return pipe 205 to achieve repeated reuse of the gas in the low-temperature chamber, which can avoid waste of the low-temperature gas in the low-temperature chamber on the one hand, and avoid toxic and harmful substances carried in the gas from being discharged and causing environmental pollution on the other hand, thereby providing a good working environment for the staff.

[0066] like Figures 1 to 10 As shown, the air intake mechanism 3 is installed on the top of the shell 1, and the air intake mechanism 3 is used to transport low-temperature gas into the shell 1. The low-temperature gas can be used to efficiently cool the filaments moving in the shell 1.

[0067] The air intake mechanism 3 includes a first air pump 301, the air outlet of the first air pump 301 is connected to a cooling mechanism, the cooling mechanism is connected to an air delivery pipe 302, and the air delivery pipes 302 are respectively connected to a pair of air distribution covers 204. When the first air pump 301 is running, the gas extracted by the first air pump 301 is cooled by the cooling mechanism and can enter the pair of air distribution covers 204 through the air delivery pipe 302, so that the gas can enter the high-temperature cavity and the low-temperature cavity respectively.

[0068] In addition, a control valve is connected to the gas delivery pipe 302, and the control valve corresponds to the lower gas distribution hood 204. When the infrared thermometer 401 monitors that the temperature of the filament is still high, the control valve is opened, so that low-temperature gas also enters the lower gas distribution hood 204, and the gas enters the first conveying roller 2 through the hollow tube 203, and then sprays to the low-temperature cavity through a plurality of cooling holes 202, so as to further cool the filament moving in the low-temperature cavity.

[0069] If the temperature of the filament monitored by the infrared thermometer 401 is at room temperature, the control valve is closed, and low-temperature gas will not enter the lower gas distribution hood 204, so that a large amount of low-temperature gas will enter the low-temperature cavity, thereby greatly improving the utilization rate of the low-temperature gas, avoiding the waste of low-temperature gas, and reducing the overall energy consumption.

[0070] like Figures 1 to 10 As shown, the cooling mechanism includes a cooling box 303, a second partition 304 is provided in the cooling box 303, a connecting hole 305 is drilled on the second partition 304, a cooling chamber and a drying chamber are formed between the second partition 304 and the side wall of the cooling box 303, and the cooling chamber is connected to the drying chamber through the connecting hole 305.

At the same time, the cooling liquid 306 can also remove impurities in the gas to avoid the influence of impurities on the cooling of the filament, thereby ensuring the cooling quality of the filament.

[0072] Preferably, the cooling liquid 306 is water.

[0073] In addition, a first grid 307 is installed in the drying chamber, and a drying cotton 308 is arranged on the first grid 307. One end of the gas delivery pipe 302 is arranged at the lower side of the first grid 307. The cooled gas will pass through the drying cotton 308 for drying, which is used to remove water vapor in the gas to prevent the water vapor from affecting the filaments, that is, to prevent water drops or water film from remaining on the surface of the filaments, thereby ensuring the cooling effect of the filaments.

[0074] Specifically, the cooling box 303 is provided with a replenishing port 309, which corresponds to the cooling liquid 306. In order to further improve the cooling effect of the cooling liquid 306 on the gas, ice cubes can be added to the cooling liquid 306 through the replenishing port 309 to reduce the temperature of the cooling liquid 306, so that the temperature of the cooling liquid 306 is lower than the room temperature.

[0075] Preferably, the first air pump 301 is provided with a first liquid exchange pipe and a first cover door, the first liquid exchange pipe is connected with the cooling chamber, and the first cover door corresponds to the drying chamber.

[0079] like Figures 1 to 13As shown, the gas processing mechanism 5 is installed on the side wall of the shell 1, and the gas processing mechanism 5 is connected with the high-temperature chamber. The gas processing mechanism 5 is used to process the gas discharged from the high-temperature chamber. On the one hand, the gas can be purified to avoid direct discharge of toxic and harmful substances carried in the gas to pollute the air, thereby creating a good working environment for the staff. On the other hand, the heat in the gas can be recovered to avoid the waste of thermal energy resources in the gas and improve the overall environmental protection effect.

[0080] The gas processing mechanism 5 includes a processing box 501, a second air pump 502 is connected to the processing box 501, an air inlet end of the second air pump 502 is connected to an air extraction pipe 503, and one end of the air extraction pipe 503 is arranged in the high temperature chamber.

[0081] In addition, a second grid is provided under the second air pump 502, on which an activated carbon layer 504 is placed.

[0083] Specifically, a heat exchange liquid 505 is provided in the processing box 501, and the heat exchange liquid 505 is provided at the lower side of the second grid. The heat exchange liquid 505 is used to exchange heat with the gas subjected to adsorption treatment, so as to recover the heat in the gas and avoid the loss of heat in the gas. At the same time, it can also prevent the gas from causing the air temperature near the housing 1 to rise, thereby creating a good working environment for the staff.

[0084] Preferably, the heat exchange fluid 505 can be domestic water, such as tap water.

[0085] In addition, a second gas collecting hood 506 is connected to the second grid, and one end of the second gas collecting hood 506 is disposed in the heat exchange liquid 505 for collecting the gas adsorbed by the activated carbon layer 504 .

[0086] Preferably, a gas outlet is provided on the side wall of the processing box 501, and the height of the gas outlet is higher than the height of the heat exchange liquid 505, so that the gas that has undergone heat exchange in the processing box 501 can be discharged.

When the gas enters the heat exchange liquid 505 through the second gas collecting cover 506, the purification ball 508 moves irregularly at the bottom of the treatment box 501 under the action of the gas. When the purification ball 508 contacts the puncture needle 509, the puncture needle 509 punctures the inner film 5081 through the hole 5084, so that the gel liquid 5082 enters the heat exchange liquid 505. The gel liquid 5082 will wrap the impurities in the heat exchange liquid 505, so that the volume of the impurities increases.

The slag discharge pipe is used to discharge the sediment filtered at the bottom of the processing box 501, and the second liquid exchange pipe is used to discharge the heat exchange liquid 505 for the use of the heat exchange liquid 505.

[0091] like Figures 1 to 13 As shown, a plurality of puncture needles 509 are provided at the bottom of the processing box 501 for puncturing the inner film 5081 to release the gel liquid 5082 , and the gel liquid 5082 is used to wrap the impurities in the heat exchange liquid 505 .

[0092] The side wall of the treatment box 501 is connected with a sealing tube 510, and the sealing tube 510 is connected with an adding tube 511. The sealing tube 510 is connected with the inside of the treatment box 501 through the adding tube 511.

[0095] A method for producing PTFE-based superconducting polypropylene filaments comprises the following steps:

[0096] S1. Selecting a composite material of polypropylene plastic particles, PTFE and a waterproofing agent as a raw material, and pretreating the raw material, wherein the pretreatment process includes impurity removal, drying and mixing processes;

[0097] S2, placing the pretreated raw materials into a melting tank, melting them at high temperature to form a molten raw material liquid;

[0098] S3, the raw material liquid is sprayed out from the spinning nozzle of the spinning machine, stretched at the spinneret to form filaments, and then rapidly cooled by the housing 1 so that the filaments can be quickly solidified;

[0099] S4. The filaments are wound, coated and processed to become polypropylene filament products. The polypropylene filaments prepared by the present invention have good superconducting water effect due to the composite material of PTFE and waterproofing agent added, which meets the production requirements.

[0100] In S3, the specific use process of the shell 1 is as follows:

[0101] S301, the filament enters the housing 1 from the feed port 103, passes through the high temperature chamber, the low temperature chamber and the buffer chamber in sequence, and finally is discharged from the discharge port 104 to enter the subsequent process. When the filament moves in the housing 1, it will bypass a plurality of first conveying rollers 2 and a plurality of second conveying rollers 201 respectively;

[0102] S302, when the filament moves in the high-temperature chamber, the first air pump 301 is operated, and the first air pump 301 extracts external gas, and the gas first enters the cooling liquid 306 for cooling, and then enters the drying chamber through the connecting hole 305, and after being dried by the drying cotton 308, enters the upper side gas distribution cover 204 through the air delivery pipe 302, and the gas in the upper side gas distribution cover 204 enters the first conveying roller 2 through the hollow tube 203, and is discharged to the high-temperature chamber through a plurality of cooling holes 202. Since the filament bypasses the first conveying roller 2, the gas discharged through the first conveying roller 2 can directly act on the filament, which can not only ensure the cooling efficiency of the filament, but also ensure the cooling uniformity of the filament;

[0103] S303, when the filament passes through the infrared thermometer 401, the infrared thermometer 401 can detect the temperature of the filament. If the temperature of the filament is still high, the control valve is opened, and the gas extracted by the first air pump 301 will also enter the lower gas distribution cover 204. The gas in the lower gas distribution cover 204 enters the first conveying roller 2 through the hollow tube 203, and is discharged to the low-temperature cavity through a plurality of cooling holes 202. The gas discharged by the first conveying roller 2 is used to further cool the filament moving in the low-temperature cavity, so that the filament is cooled to room temperature;

[0104] S304, as the gas in the low-temperature chamber gradually increases, part of the gas in the low-temperature chamber enters the gas distribution part 107 through the first gas collecting cover 106 and the connecting pipe 105, and is sprayed toward the filaments in the buffer chamber through a plurality of spray holes 108, so as to achieve further cooling of the filaments;

[0105] S305, part of the gas in the low-temperature chamber will also be re-absorbed by the first gas pump 301 through the reflux pipe 205, so as to realize the repeated reuse of the gas in the low-temperature chamber, avoid the waste of low-temperature gas, and also avoid the toxic and harmful substances carried in the gas from being directly discharged to cause environmental pollution;

[0106] S306, the gas in the high temperature chamber enters the processing box 501 through the exhaust pipe 503 under the action of the second air pump 502, and after being adsorbed by the activated carbon layer 504, enters the heat exchange liquid 505 through the second gas collecting cover 506, and is discharged from the processing box 501 after heat exchange with the heat exchange liquid 505, so as to recover the heat in the gas discharged from the high temperature chamber and avoid the loss of heat in the gas;

[0107] S307. When the gas enters the heat exchange liquid 505 through the second gas collecting hood 506, the purification ball 508 moves irregularly at the bottom of the processing box 501 under the action of the gas. When the purification ball 508 contacts the needle 509, the needle 509 pierces the inner membrane 5081 through the hole 5084, so that the gel liquid 5082 enters the heat exchange liquid 505. The gel liquid 5082 will wrap the impurities in the heat exchange liquid 505, so that the volume of the impurities increases. The impurities with increased volume will be blocked by the filter cloth 507 and settle at the bottom of the processing box 501, so that the heat exchange liquid 505 remains pure for the subsequent use of the heat exchange liquid 505.
