Description

Technical Field

[0001] This utility model relates to the field of PET monofilament production technology, and in particular to a raw material drying device for PET monofilament production. Background Technology

[0002] In the production of PET monofilament, drying the raw materials is a crucial step because PET (polyethylene terephthalate) is hygroscopic, and moisture can affect its processing performance and the quality of the final product. The main function of the drying equipment is to reduce the moisture content of the PET raw materials to the level required by the process through heating and dehumidification.

[0003] This utility model, with publication number CN221992298U, provides a chemical raw material drying device, including a fixed frame. A first rotating shaft and a second rotating shaft are rotatably connected to the inner side of the fixed frame. A fixed sleeve is provided between the first and second rotating shafts. A material cylinder with a feed inlet at the top is fixedly mounted inside the fixed sleeve. A lifting mechanism is fixedly installed on the outer side of the fixed frame, and a movable seat located above the fixed frame is movably mounted on the outer side of the lifting mechanism. This chemical raw material drying device, driven by a first and second electric telescopic rod, can move the movable seat upwards along the axial direction of the first and second fixed rods, simultaneously opening the feed inlet at the top of the material cylinder. Driven by a second motor, it can also drive the material cylinder to rotate around the axial direction of the first and second rotating shafts, thereby discharging the chemical raw material inside the material cylinder from the feed inlet. At this point, the interior of the material cylinder is completely exposed, facilitating the cleaning of any residual chemical raw material inside the cylinder.

[0004] The device disclosed in the above utility model requires the first electric telescopic rod and the second telescopic rod to move the moving seat out synchronously, and then the second motor to discharge the material from the feed port at the top of the material cylinder. This method is inconvenient for feeding and discharging materials and has a high production cost. Utility Model Content

[0005] The purpose of this invention is to provide a raw material drying device for PET monofilament production, so as to solve the problems of inconvenient feeding and discharging and high production cost mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material drying device for PET monofilament production, including a mounting frame, a drying barrel mounted on the mounting frame, heating wires arranged around the drying barrel, a first motor mounted on the drying barrel, a stirring part mounted on the output shaft of the first motor, the end of the stirring part away from the first motor being located inside the drying barrel, a feed inlet on the drying barrel, a feed hopper mounted at the feed inlet, a conical bottom for the drying barrel, and a discharge outlet at its bottom end.

[0007] Preferably, the stirring part includes a drive shaft mounted on a first motor, a connecting seat is mounted at the bottom end of the drive shaft, and a plurality of stirring rods are circumferentially distributed on the connecting seat.

[0008] Preferably, the vertical coverage areas of the connecting seat and the feed inlet do not overlap.

[0009] Preferably, an insulation shell is installed around the drying drum, the heating wire is located between the drying drum and the insulation shell, and the bottom of the insulation shell is connected to the mounting frame.

[0010] Preferably, the drying drum is equipped with a vacuum pump, and the feed hopper and the discharge port are respectively equipped with a feed valve and a discharge valve.

[0011] Preferably, a conveying pipe is provided below the discharge port, and a screw rod is provided inside the conveying pipe. One end of the screw rod is connected to the output shaft of a second motor.

[0012] Preferably, a connecting plate is mounted on the mounting bracket, the second motor is mounted on the connecting plate, and the conveying pipe is mounted on the end of the connecting plate away from the second motor.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, raw materials are fed into a drying drum via a feeding hopper, and then heated by a heating wire to raise the temperature inside the drum, thereby reducing the humidity of the raw materials. Simultaneously, a first motor is activated, driving a stirring unit to agitate the raw materials within the drying drum, ensuring more even heating and further improving drying efficiency. The dried raw materials are then discharged from the device through the discharge port, completing the unified processing of the dried materials. This device, with its feeding inlet, feeding hopper, and discharge port, can handle the feeding and discharging of raw materials, avoiding the need for multiple drive components found in existing technologies. This effectively reduces production costs, simplifies the drying process, and further improves drying efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A raw material drying device for PET monofilament production includes a mounting frame 1, a drying barrel 2 mounted on the mounting frame 1, a heating wire 8 arranged around the drying barrel 2, a first motor 3 mounted on the drying barrel 2, a stirring part 4 mounted on the output shaft of the first motor 3, the end of the stirring part 4 away from the first motor 3 being located inside the drying barrel 2, a feed inlet 5 opened on the drying barrel 2, a feed hopper 6 installed at the feed inlet 5, and a conical bottom with a discharge outlet 7 at its bottom end.

[0022] In operation, the raw materials are fed into the drying drum 2 through the feed hopper 6. The drying drum 2 is then heated by the heating wire 8, raising the temperature inside and reducing the humidity of the raw materials. Simultaneously, the first motor 3 is activated, driving the stirring unit 4 to rotate and stir the raw materials in the drying drum 2, ensuring more even heating and further improving the drying efficiency. The dried raw materials are then discharged from the device through the discharge port 7, completing the unified processing of the dried materials. This device can complete the feeding and discharging of raw materials through the feed inlet, feed hopper, and discharge port, avoiding the need for multiple drive components in existing technologies. This effectively reduces production costs, simplifies the drying process, and further improves drying efficiency.

[0023] Specifically, in this embodiment, the stirring part 4 includes a drive shaft 9 mounted on the first motor 3. A connecting seat 10 is mounted at the bottom end of the drive shaft 9. Several stirring rods 11 are distributed around the connecting seat 10, so that when the first motor 3 drives the stirring part 4 to run, the drive shaft 9 will drive the connecting seat 10 to rotate synchronously, thereby driving the several stirring rods 11 to rotate, thereby achieving the purpose of stirring the raw materials in the drying barrel 2.

[0024] Specifically, in this embodiment, the vertical coverage of the connecting seat 10 and the feed inlet 5 do not overlap, so that the raw materials fed into the drying barrel 2 from the feed inlet 5 will fall directly into the drying barrel 2, thereby avoiding the situation where the raw materials fall onto the connecting seat 10, and ensuring that the raw materials in the drying barrel 2 are at the same degree of dryness.

[0025] Specifically, in this embodiment, an insulation shell 12 is installed around the drying drum 2, and the heating wire 8 is located between the drying drum 2 and the insulation shell 12. The bottom of the insulation shell 12 is connected to the mounting frame 1, so that the temperature generated by the heating wire 8 can be kept inside the insulation shell 12, so that the heat can be effectively absorbed by the drying drum 2 and heat loss can be avoided.

[0026] Specifically, in this embodiment, a vacuum pump 13 is installed on the drying drum 2, and a feed valve 14 and a discharge valve 15 are respectively installed on the feed hopper 6 and the discharge port 7. When the feed valve 14 and the discharge valve 15 are in conjunction with the operation of the vacuum pump 13, the drying drum 2 can be in a vacuum state, thereby extracting the moisture from the raw materials and improving the drying efficiency of the raw materials.

[0027] Specifically, in this embodiment, a conveying pipe 16 is provided below the discharge port 7, and a screw rod 17 is provided inside the conveying pipe 16. One end of the screw rod 17 is connected to the output shaft of the second motor 18, so that the raw material can enter the conveying pipe 16 through the discharge port 7 and fall on the screw rod 17. When the second motor 18 rotates, it can drive the screw rod 17 to rotate synchronously, thereby completing the quantitative conveying of the raw material.

[0028] Specifically, in this embodiment, a connecting plate 19 is installed on the mounting frame 1, the second motor 18 is installed on the connecting plate 19, and the conveying pipe 16 is installed on the end of the connecting plate 19 away from the second motor 18, so that the output end of the second motor 18 can be connected to the screw rod 17 through the connecting plate 19, thereby providing support for the second motor 18. At the same time, the setting of the connecting plate 19 makes the end of the conveying pipe 16 near the second motor 18 closed, thereby preventing raw materials from leaking from that point.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
