Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a masterbatch dryer for nylon filament production. Background Technology

[0002] The main type of nylon is aliphatic polyamide fiber, which can be synthesized from a single monomer, such as lactam or amino acid. In this case, the Arabic numerals after the name of nylon indicate the number of carbon atoms in the lactam or amino acid used, such as nylon 6, nylon 11, etc. The production of colored nylon 6 fiber generally adopts the method of adding colored masterbatch to polymer melt to spin colored fiber. In order to ensure the normal operation of the process, the masterbatch needs to be dried before being added, which is generally accomplished by a masterbatch dryer.

[0003] In existing technologies, some masterbatch dryers have poor drying efficiency, and the screw conveyor and motor of the masterbatch dryer are driven by gears or sprockets and chains, resulting in low transmission efficiency and unstable operation. To address these issues, application number 201320126971.1 discloses a novel masterbatch dryer for producing nylon 6 colored fibers. This dryer includes an outer support, a hopper, a screw feeding device, and a motor. The hopper is mounted on the outer support. The dryer also includes a lower base and a fan. The screw feeding device and motor are both fixed to the lower base. The motor shaft is connected to the screw feeding device via a coupling. The discharge port of the hopper is connected to the screw feeding device, and the discharge pipe of the screw feeding device passes through the lower base. An air duct is connected to the air outlet of the blower, and the other end of the air duct is connected to the hopper. A heating device is fitted over the air duct, and an exhaust port is also provided on the hopper. The novel masterbatch dryer for producing nylon 6 colored fiber obtained by this utility model has a good transmission effect between the motor and the screw feeding device, and the masterbatch conveying is more stable.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following drawbacks: Most existing methods involve air-drying the plastic masterbatch in the drying drum, after which the machine needs to be stopped to discharge the dried plastic masterbatch from the drying drum before the next batch of plastic masterbatch to be dried is transported into the drying drum. This results in the inability to continuously process the plastic masterbatch, significantly reducing processing efficiency, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a masterbatch dryer for nylon filament production, which has the effect of continuous drying of masterbatch.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a masterbatch dryer for nylon filament production, comprising a drying chamber, a drying mechanism, and a control panel for drying masterbatch used in nylon filament processing;

[0010] A further feature of this invention is that the hot air blower is connected to the control panel, and the hot air blower is controlled by a preset program in the control panel.

[0011] A further feature of this invention is that a horizontal plate is fixedly installed inside the drying chamber, the horizontal plate corresponds to the mesh belt, and a feed pipe is provided at the top of the drying chamber and located on one side of the horizontal plate. The horizontal plate can be used to push the masterbatch flat, thereby ensuring that the masterbatch is evenly laid on the mesh belt.

[0012] A further feature of this invention is that the top of the flow equalization plate has multiple exhaust holes, all of which correspond to the mesh belt, to facilitate the drying of the masterbatch.

[0013] A further feature of this invention is that both sides of the mesh belt are in contact with the drying chamber, and the mesh belt is adapted to the drying chamber to prevent masterbatch leakage.

[0014] A further feature of this invention is that a guide plate is fixedly installed at one end of the drying chamber, and one end of the guide plate is in contact with the mesh belt. A discharge hopper is fixedly installed at one end of the drying chamber, and the discharge hopper corresponds to the guide plate. The dried masterbatch is discharged from the drying chamber and transported to the discharge hopper by the action of the guide plate, and is then transported by the discharge hopper.

[0015] A further feature of this invention is that the top of the drying chamber is provided with multiple heat dissipation windows, and the top of the drying chamber is sealed with a square sleeve, which is fitted over the multiple heat dissipation windows. An exhaust pipe is sealed to the square sleeve for discharging hot steam.

[0016] A further feature of this invention is that an electric motor is fixedly installed on the drying chamber, and the output end of the electric motor is fixedly connected to one end of one of the two transmission rollers. Driven by the electric motor, the corresponding transmission roller rotates on the drying chamber and drives the mesh belt, so that the mesh belt conveys the masterbatch to the guide plate. The electric motor is connected to the control panel, and the electric motor is controlled by a preset program in the control panel.

[0017] The beneficial effects of this utility model are: through the coordinated design between the drying chamber, transmission roller, mesh belt, motor, drying mechanism, guide plate, discharge hopper and control panel, not only can the masterbatch be dried, but the dried masterbatch can also be automatically discharged. This achieves the effect of continuous processing of masterbatch by feeding and drying on one side and discharging the dried masterbatch on the other, which greatly improves the processing efficiency.

[0027] Reference Figures 1-5 A masterbatch dryer for nylon filament production includes a drying chamber 1 for drying masterbatch used in nylon filament processing, a drying mechanism, and a control panel 10.

[0028] Two drive rollers 2 are rotatably connected inside the drying chamber 1.

The drying chamber 1 is a drying mechanism for drying the masterbatch for nylon filament production. A control panel 10 is fixedly installed on one side of the drying chamber 1. The drying mechanism is connected to the control panel 10.

[0029] The drying mechanism includes a flow equalization plate 4, a turning plate 5, a hot air blower 7, and a horizontal plate 12. The flow equalization plate 4 is fixedly installed in the drying chamber 1, and the flow equalization plate 4 corresponds to the mesh belt 3. Multiple turning plates 5 are fixedly installed in the drying chamber 1, and one end of each turning plate 5 is in contact with the mesh belt 3. The multiple turning plates 5 are arranged alternately. Through the coordinated design between the drying chamber 1, the transmission roller 2, the mesh belt 3, the motor 6, the drying mechanism, the guide plate 8, the discharge hopper 9, and the control panel 10, not only can the masterbatch be dried, but the dried masterbatch can also be automatically discharged. This achieves the effect of continuous processing of masterbatch, which involves feeding and drying the masterbatch while discharging the dried masterbatch.

[0030] In this method, a hot air blower 7 is fixedly installed on the drying chamber 1. One end of the hot air blower 7 is sealed and connected to an air pipe, and the other end of the air pipe is sealed and connected to the flow equalization plate 4. Through the drive of the hot air blower 7 and the cooperation of the air pipe, hot air can be transported into the flow equalization plate 4. Then, it is discharged through multiple exhaust holes on the top of the flow equalization plate 4 and passes through the mesh belt 3 and acts on the masterbatch, thereby achieving the effect of drying the masterbatch.

[0031] In this method, the hot air blower 7 is connected to the control panel 10, and the hot air blower 7 is controlled by a preset program in the control panel 10.

[0032] In this method, a horizontal plate 12 is fixedly installed inside the drying chamber 1. The horizontal plate 12 corresponds to the mesh belt 3. The top of the drying chamber 1 is provided with a feed pipe located on one side of the horizontal plate 12. The horizontal plate 12 can be used to push the masterbatch flat, thereby making the masterbatch evenly laid on the mesh belt 3.

[0033] In this method, the top of the flow equalization plate 4 is provided with multiple exhaust holes, all of which correspond to the mesh belt 3, to facilitate the drying of the masterbatch.

[0034] In this method, both sides of the mesh belt 3 are in contact with the drying chamber 1, and the mesh belt 3 is adapted to the drying chamber 1 to avoid masterbatch leakage.

[0035] In this method, a guide plate 8 is fixedly installed at one end of the drying chamber 1. One end of the guide plate 8 is in contact with the mesh belt 3. The guide plate 8 and the mesh belt 3 are adapted to each other. A discharge hopper 9 is fixedly installed at one end of the drying chamber 1. The discharge hopper 9 corresponds to the guide plate 8. The dried masterbatch is discharged from the drying chamber 1 and transported to the discharge hopper 9 by the action of the guide plate 8. The discharge hopper 9 is used to transport the masterbatch. A valve is provided at one end of the discharge hopper 9.

[0036] In this method, the top of the drying chamber 1 is provided with multiple heat dissipation windows, and the top of the drying chamber 1 is sealed with a square sleeve 11, which is fitted onto the multiple heat dissipation windows. An exhaust pipe is sealed on the square sleeve 11 for discharging hot steam.

[0037] In this method, a motor 6 is fixedly installed on the drying chamber 1. The output end of the motor 6 is fixedly connected to one end of one of the two transmission rollers 2. Driven by the motor 6, the corresponding transmission roller 2 rotates on the drying chamber 1 and is driven by the mesh belt 3, so that the mesh belt 3 conveys the masterbatch to the guide plate 8. The motor 6 is connected to the control panel 10. The preset program in the control panel 10 controls the motor 6. The motor 6 is a servo motor, and the servo motor is connected to the control panel 10 along with the frequency converter.

[0038] Working principle: When in use, first connect the power supply and adjust the hot air blower 7 and the motor 6 through the preset program in the control panel 10;

[0039] First, the masterbatch is conveyed to the mesh belt 3 inside the drying chamber 1 through the feed pipe at the top of the drying chamber 1. At the same time, the corresponding transmission roller 2 is driven by the motor 6 to rotate on the drying chamber 1 and drive the mesh belt 3, so that the mesh belt 3 conveys the masterbatch to the guide plate 8. During this process, the cross plate 12 can be used to flatten the masterbatch, so that the masterbatch is evenly spread on the mesh belt 3. Then, the hot air is conveyed to the equalization plate 4 by the drive of the hot air fan 7 and the cooperation of the air pipe. Then, the hot air is discharged through multiple exhaust holes at the top of the equalization plate 4, passes through the mesh belt 3 and acts on the masterbatch, thereby achieving the effect of drying the masterbatch. During the process of conveying the masterbatch by the mesh belt 3, the masterbatch interacts with multiple turning plates 5 in sequence. At this time, since the multiple turning plates 5 are all conical, the masterbatch can be pushed to both sides, thereby achieving the effect of turning the masterbatch, further improving the drying efficiency of the masterbatch.

[0040] Finally, the dried masterbatch is discharged from the drying chamber 1 and transported to the discharge hopper 9 by the guide plate 8, and then transported by the discharge hopper 9.

[0041] The technological advancements of this invention compared to existing technologies are: through the cooperation of various components, continuous drying of masterbatch can be achieved, improving processing efficiency; moreover, the structure is simple and more practical.
