Abstract
Description
Technical Field
[0001] This invention relates to the field of nylon production technology, specifically to a highly efficient apparatus and method for preparing nylon masterbatch. Background Technology
[0002] Nylon generally refers to synthetic fiber. It was developed by the distinguished American scientist Carlos Carothers and his research team, and was the world's first synthetic fiber. The advent of nylon revolutionized textiles; its synthesis was a major breakthrough in the synthetic fiber industry and a significant milestone in polymer chemistry. Nylon raw material production typically involves processing nylon raw materials into strips, water-cooling them to form shapes, and then cutting them into sheets to become nylon granules. Due to nylon's high water absorption, the nylon granules need to be dried to ultimately form nylon masterbatch (the finished raw material).
[0003] Traditional drying equipment typically involves placing nylon granules in a drying chamber and using internal heating and stirring devices to dehumidify and dry them. However, because the nylon granules tend to clump together, it's difficult to ensure even heating and drying. Furthermore, the clumping results in longer drying times and lower efficiency, hindering the production of nylon masterbatch. Additionally, nylon granules may stick together due to moisture or other factors, and traditional drying equipment cannot effectively separate these clumps, further complicating the drying and subsequent use of the nylon granules.
[0004] Based on this, a highly efficient apparatus and method for preparing nylon masterbatch are provided, which can eliminate the drawbacks of existing apparatus. Summary of the Invention

[0034] In one embodiment, such as Figures 1-9 As shown, a high-efficiency preparation device for nylon masterbatch includes a drying chamber 11. A mounting base plate 23 is fixedly provided at the lower end of the drying chamber 11, and several supporting legs are fixedly provided at the lower end of the mounting base plate 23. A rotating plate 12 is fitted inside the drying chamber 11, with one end rotatably mounted inside the drying chamber 11. Several through holes are provided at the upper end of the rotating plate 12. The rotating plate 12 is inclined. A cam 13 is fitted at the lower end of the rotating plate 12, with its two ends rotating shafts rotatably mounted inside the drying chamber 11. One end of the rotating shaft of the cam 13 is connected to the output end of a first motor 14. The first motor 14 is fixedly mounted on one side of the drying chamber 11. The bottom of the drying chamber 11 is equipped with a drying assembly for drying nylon granules. One end of the discharge port on one side of the drying chamber 11 is connected to one end of the guide pipe 34, and the other end of the guide pipe 34 is connected to the inlet end of the storage tank 35. The storage tank 35 is fixedly mounted in a circular mounting hole at the top of the drying chamber 11. A valve is connected to the output end of the storage tank 35. The drying chamber 11 is connected to the output end of the mixing tank 24 through the first discharge pipe. The mixing tank 24 is fixedly mounted on top of the storage tank 35, and a valve is connected to the mixing tank 24. The mixing chamber 24 has an inlet pipe. A filter plate 25 is fixedly installed inside the mixing chamber 24. A sleeve shaft 27 is rotatably mounted within a circular perforation at the upper end of the mixing chamber 24. A fixed frame is symmetrically mounted at one end of the sleeve shaft 27, and a rotating roller 26 is fitted onto the fixed frame. Several stirring rods are mounted on the sleeve shaft 27. A drive shaft 29 is rotatably mounted within a circular perforation at one end of the sleeve shaft 27. One end of the drive shaft 29 is rotatably connected to the bottom of the storage tank 35. An external spline is provided at the other end of the drive shaft 29. An internal spline is provided at the other end of the sleeve shaft 27 at a position corresponding to the external spline. The upper end of the mixing chamber 24 has a design for facilitating the adjustment of the sleeve shaft. 27. A support and separation assembly for support and separation; one end of the drive shaft 29 is provided with a drive assembly to facilitate the rotation of the drive shaft 29; the drying chamber 11 is provided with a condensation mechanism to facilitate the condensation and collection of moisture in the air inside the nylon granule drying chamber 11; the storage box 35 is provided with a conveying mechanism for conveying nylon granules for multiple drying operations; the condensation mechanism facilitates the condensation and collection of moisture in the air inside the drying chamber 11, facilitating the reuse of the air inside the drying chamber 11; the conveying mechanism facilitates the detection of dried nylon granules and the conveying of nylon granules for multiple drying operations.
[0035] The drying assembly includes two fans 16, which are fixedly installed inside the lower end of the drying chamber 11. The output end of each fan 16 is connected to a heating chamber 15, and the output end of the heating chamber 15 is connected to an air outlet box. The upper end of the air outlet box has several air outlet holes. The input end of each fan 16 is connected to one end of a gas transmission pipe 17, and the other end of the gas transmission pipe 17 is connected to the upper end of the drying chamber 11. In use, when the nylon granules fall through the first discharge pipe to the upper end of the rotating plate 12, the fans 16 are started. The fans 16 deliver air to the interior of the heating chamber 15, which heats the air through internal heating wires. The heated air enters the air outlet box and is then discharged through the air outlet holes at the upper end of the air outlet box. The heated air heats and dehumidifies the nylon granules on the upper end of the rotating plate 12. The heated air is then reused through the gas transmission pipe 17, which facilitates rapid heating of the air.
[0036] The support separation assembly includes a rotating ring rotatably mounted on the sleeve shaft 27. The rotating ring is symmetrically provided with extension plates. The lower end of the extension plates is fixedly connected to the output end of the electric push rod 28. The electric push rod 28 is fixedly mounted on the upper end of the drying chamber 11. When the sleeve shaft 27 is not in use, the electric push rod 28 is started, and the electric push rod 28 drives the sleeve shaft 27 to move. When the inner spline at one end of the sleeve shaft 27 disengages from the outer spline at one end of the drive shaft 29, the sleeve shaft 27 stops rotating. At the same time, the rotating roller 26 is in close contact with the upper end of the filter plate 25.
[0037] The drive assembly includes a worm gear 30, which is fixedly mounted on one end of the transmission shaft 29. A worm 31 is fitted onto the worm gear 30. One end of the worm 31 is rotatably mounted on one side of the regulating box 33, which is fixedly mounted on the upper end of the mixing box 24. The other end of the worm 31 is fixedly connected to the output end of the second motor 32, which is fixedly mounted inside the regulating box 33. In use, the second motor 32 is started, and its output shaft drives the worm 31 to rotate. The worm 31 meshes with the worm gear 30 and rotates, which in turn drives the transmission shaft 29 to rotate. The transmission shaft 29 then drives the sleeve shaft 27 to rotate via an external spline.
[0038] The condensation mechanism includes two symmetrically arranged condensing plates 18, both ends of which are fixed inside the drying chamber 11. The condensing plates 18 are inclined, and a plurality of cooling fins 19 are provided on one side of each condensing plate 18. A guide plate 20 is provided on the other side of the condensing plate 18, and the guide plate 20 is also inclined. The condensing plates 18 and the guide plate 20 together form a guide channel. A liquid outlet is provided on one side of the drying chamber 11 at a position corresponding to the guide channel. During use, the used hot gas rises to the drying chamber 11. At the top, the cooling chip 19 is activated, and the cooling chip 19 cools the condenser plate 18. When hot air containing water comes into contact with one side of the condenser plate 18, the condenser plate 18 condenses the water in the hot air. The condensed water gathers on the surface of the condenser plate 18. Since the condenser plate 18 is inclined, the water droplets flow along the surface of the condenser plate 18. At the same time, the guide plate 20 can prevent the water droplets from falling into the drying chamber 11. Subsequently, the water droplets fall between the condenser plate 18 and the guide plate 20. A collection component is provided on one side of the drying chamber 11 to facilitate the collection of condensate.
[0039] The collection assembly includes a connecting pipe 21, which is positioned at the outlet on one side of the drying chamber 11. A conduit is connected to the lower end of the connecting pipe 21, and one end of the conduit is connected to a collection box 22. The collection box 22 is mounted on a mounting frame on one side of the drying chamber 11. In use, the condensed water flows into the connecting pipe 21 through the outlet and then into the collection box 22 through the conduit. The collection box 22 collects the condensed water.
[0040] The collection box 22 is equipped with an observation window made of transparent material, which allows staff to easily observe the liquid level inside the collection box 22 during use.
[0041] The conveying mechanism includes a spiral plate 37, which is fixedly mounted on a drive shaft 29. A transmission cylinder 36 is fitted onto the spiral plate 37 and is fixedly mounted inside the upper part of the storage box 35. The transmission cylinder 36 is connected to the drying chamber 11 through a second discharge pipe. A rotating sleeve 38 is rotatably mounted at the lower end of the transmission cylinder 36. The rotating sleeve 38 is fixedly connected to the drive shaft 29 through a connecting rod. The rotating sleeve 38 has an inlet. In use, when it is necessary to repeatedly dry the nylon granules, the drive shaft 29 rotates in the opposite direction. The reverse rotation of the drive shaft 29 drives the spiral plate 37 to rotate. The spiral plate 37 and the transmission cylinder 36 cooperate to transport the nylon granules through the second discharge pipe into the drying chamber 11 for re-drying.
[0042] A humidity sensor 39 is fitted onto the rotating sleeve 38. When in use, the rotating sleeve 38 rotates, causing the humidity sensor 39 to rotate as well. The rotation of the humidity sensor 39 facilitates the detection of the humidity of the nylon particles inside the storage bin 35, ensuring the accuracy of the detection data. The output end of the humidity sensor 39 is electrically connected to the remote control terminal, and the humidity sensor 39 transmits the detected values to the input end of the remote control terminal for easy viewing by the staff.
[0043] The rotating sleeve 38 is provided with an arc-shaped deflector 40. The arc-shaped deflector 40 is arc-shaped. When the drive shaft 29 transmits nylon particles, the arc-shaped deflector 40 can move the nylon particles into the feed port on one side of the rotating sleeve 38. When it is necessary to discharge the nylon particles, the rotating sleeve 38 rotates, and the arc-shaped deflector 40 can move the nylon masterbatch to the discharge port, so as to facilitate the discharge of the nylon masterbatch.
[0044] The above embodiment discloses a method for using a high-efficiency nylon masterbatch preparation device. When drying the nylon granules is required, the nylon granules are added into the mixing chamber 24 through the feed pipe. Simultaneously, the second motor 32 is started. The output shaft of the second motor 32 drives the worm gear 31 to rotate. The worm gear 31 meshes with the worm wheel 30 and rotates. The worm wheel 30 drives the transmission shaft 29 to rotate. The transmission shaft 29 drives the sleeve shaft 27 to rotate via an external spline. The sleeve shaft 27 drives the stirring rod and the rotating roller 26 to rotate. The rotating roller 26 can crush and break up the agglomerated granules. Subsequently, the nylon granules fall through the filter holes at the upper end of the filter screen 25 and... The material then falls through the first discharge pipe to the upper end of the rotating plate 12. The first motor 14 and fan 16 are then started. The first motor 14 drives the cam 13 to rotate, and the cam 13 causes the rotating plate 12 to vibrate. This vibration facilitates the movement of the nylon particles at the upper end of the rotating plate 12. The fan 16 delivers air to the heating chamber 15, where it heats the air using internal heating wires. The heated air enters the air outlet box and is then discharged through the air outlet at the upper end of the air outlet box. This heated air dehumidifies the nylon particles at the upper end of the rotating plate 12. The used hot air rises to the upper end of the drying chamber 11, and the process is then initiated. Cooling element 19 cools condenser plate 18. When hot air containing water comes into contact with one side of condenser plate 18, condenser plate 18 condenses the water in the hot air. The condensed water collects on the surface of condenser plate 18. Since condenser plate 18 is inclined, water droplets flow along its surface. At the same time, guide plate 20 prevents water droplets from falling into the drying chamber 11. Subsequently, water droplets fall between condenser plate 18 and guide plate 20. The condensed water flows into connecting pipe 21 through liquid outlet, and then into collection box 22 through conduit. Collection box 22 collects the condensed water, and then the dehumidified water is discharged through gas transmission pipe 17. The air is reused to facilitate rapid heating. The dried nylon granules enter the storage bin 35 through the feed pipe 34. The drive shaft 29 drives the rotating sleeve 38 to rotate, which in turn drives the humidity sensor 39. The humidity sensor 39's rotation allows for accurate detection of the humidity of the nylon granules inside the storage bin 35. The output of the humidity sensor 39 is electrically connected to a remote control terminal, transmitting the detected values to the input of the remote control terminal for easy viewing by personnel. When all the nylon granules in the mixing box 24 have entered the drying box 11, the electric push rod 28 is activated.The electric push rod 28 drives the sleeve shaft 27 to move. When the internal spline at one end of the sleeve shaft 27 disengages from the external spline at one end of the drive shaft 29, the sleeve shaft 27 stops rotating. At the same time, the rotating roller 26 is in close contact with the upper end of the filter screen plate 25. If the nylon granules do not meet the specifications, the second motor 32 rotates in the reverse direction, driving the drive shaft 29 to rotate in the reverse direction. The reverse rotation of the drive shaft 29 drives the spiral auger 37 to rotate. The spiral auger 37, in conjunction with the transmission cylinder 36, transports the nylon granules through the second discharge pipe to the drying chamber 11 for re-drying. When the nylon granules meet the standards, the second motor 32 rotates forward, the spiral auger 37 stops transporting the nylon granules, and the valve is opened. The arc-shaped deflector 40 can move the nylon masterbatch to the discharge port for easy discharge.

The worm wheel (30) drives the transmission shaft (29) to rotate. The transmission shaft (29) drives the sleeve shaft (27) to rotate through the external spline. The sleeve shaft (27) drives the stirring rod and the rotating roller (26) to rotate. The nylon granules pass through the filter holes at the top of the filter screen plate (25). The air falls and then falls through the first discharge pipe to the upper end of the rotating plate (12). Then the first motor (14) and the fan (16) are started. The first motor (14) drives the cam (13) to rotate, and the fan (16) delivers air to the heating box (15). The heating box (15) heats the air through the internal heating wire. The heated air enters the air outlet box and then the heated air is discharged through the air outlet at the upper end of the air outlet box. The heated air heats and dehumidifies the nylon particles at the upper end of the rotating plate (12). Step 2: Start the cooling chip (19). The cooling chip (19) cools the condenser plate (18). The condenser plate (18) condenses the water in the hot air. The condensed water gathers on the surface of the condenser plate (18). The water droplets flow along the surface of the condenser plate (18). Then the water droplets fall between the condenser plate (18) and the guide plate (20). The condensed water flows into the connecting pipe (21) through the liquid outlet hole, and then flows into the collection box (22) through the conduit. Step 3: Nylon granules enter the storage box (35) through the feed pipe (34). The drive shaft (29) drives the rotating sleeve (38) to rotate. When the rotating sleeve (38) rotates, it drives the humidity sensor (39) to rotate. When the humidity sensor (39) rotates, it is convenient to detect the humidity of the nylon granules inside the storage box (35). Step 4: When all the nylon particles inside the mixing box (24) have entered the drying box (11), start the electric push rod (28). The electric push rod (28) drives the sleeve shaft (27) to move. When the inner spline at one end of the sleeve shaft (27) disengages from the outer spline at one end of the drive shaft (29), the sleeve shaft (27) stops rotating. Step 5: When the nylon masterbatch needs to be re-dried, the second motor (32) rotates in the reverse direction. The second motor (32) drives the transmission shaft (29) to rotate in the reverse direction. The transmission shaft (29) rotates in the reverse direction and drives the spiral auger (37) to rotate. The spiral auger (37) cooperates with the transmission cylinder (36) to transport the nylon particles through the second discharge pipe to the drying box (11) for re-drying. Step 6: When it is necessary to discharge the nylon masterbatch, the second motor (32) rotates forward, the spiral winch (37) stops conveying the nylon particles, and at the same time the valve is opened, the arc-shaped deflector (40) can move the nylon masterbatch to the discharge port.
