Description

Technical Field

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

[0002] The application background of plastic granule drying equipment in plastic production is mainly to meet the need for drying plastic granules during the plastic production process. During plastic processing, plastic granules need to maintain a certain degree of dryness to ensure product quality and performance. Therefore, plastic granule drying equipment is required in plastic production to remove moisture from the granules. These drying devices typically employ a hot air circulation system, using heating and circulating fans to evaporate and remove moisture from the plastic granules to achieve the predetermined target moisture content.

[0003] For example, the prior art Chinese patent publication number "CN221834741U" provides a plastic granule drying device for plastic production, including a placement rack, an air inlet duct, a connecting box, a heating wire mesh, a fixing plate, a drying tube, a drying box, a front door, a rotating shaft, a motor, a drying tray, and a ventilation duct. The connecting box is fixed to the left side of the top surface of the placement rack. The air inlet duct is fixedly connected to the left end of the connecting box, and the right end is connected and fixed to the drying box fixed to the right side of the top surface of the placement rack. The fixing plate is fixed to the left part of the inner cavity of the connecting box. The heating wire mesh fixed inside the connecting box is provided on the left side of the fixing plate. Several drying tubes are provided inside the connecting box. The left and right ends of the drying tubes pass through the fixing plate and the left side wall of the drying box, respectively.

[0004] The device drives a motor to rotate the drying tray. All the plastic granules placed in the drying tray can quickly dry their own moisture under the hot air and rotation. They are then discharged out of the drying chamber through the ventilation duct, improving drying efficiency and saving time.

[0005] Existing plastic pellet drying equipment in plastic production suffers from insufficient and prolonged tumbling of the pellets within the drying unit. This inadequate drying process, particularly the repeated rotation and tumbling of hot air, results in small debris that fails to dissipate during the tumbling process, thus reducing the quality of the pellets.

[0006] Therefore, a drying device for plastic pellets in plastic production is proposed. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies where plastic granules do not tumble sufficiently and continuously inside the drying device, and fail to achieve repeated rotation and tumbling of a large number of plastic granules by blowing hot air. Therefore, this invention proposes a plastic granule drying device for plastic production.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Design a plastic pellet drying device for plastic production, including a base, a support leg fixed to the top of the base, a connecting plate fixed to the top of the support leg, a drying cylinder mounted on the side of the connecting plate, a cylinder cover mounted on one end of the drying cylinder, a first bolt connecting the surface of the cylinder cover and the end face of the drying cylinder, a rotating rod rotating through the inside of the drying cylinder, a spiral turning blade fixed to the surface of the rotating rod, a driven gear fixed to the bottom end of the rotating rod, a driving gear meshing with one side of the driven gear, support plates rotatably mounted on both sides of the driving gear, a servo motor mounted on one end of the support plates, and chip removal holes evenly distributed at the bottom end of the drying cylinder.

[0010] Furthermore, the top of the drying cylinder has an air inlet, a hot air box is installed at the top of the cylinder, an air outlet pipe is fixed at the bottom of the hot air box, the air outlet pipe is inserted into the air inlet, and a second bolt connects the bottom of both sides of the hot air box to the top of the drying cylinder.

[0011] Furthermore, a cover is connected to the top of the hot air box, a dust filter is connected to the top of the inside of the hot air box, an electric heating mesh is fixed to the bottom of the inside of the hot air box, a blower is installed at the top of the base, a blower pipe is connected to the top of the blower, and the top of the blower pipe passes through the cover and is inserted into the top of the inside of the hot air box.

[0012] Furthermore, the base is horizontally positioned, the support legs are vertically positioned, the connecting plate is horizontally positioned, and the drying cylinder is inclined, with a rectangular structure on the outside and a circular cylindrical structure on the inside.

[0013] Furthermore, the rotating rod is inclined and rotates through the cylinder cover; both the driven gear and the driving gear are inclined and mesh with each other for transmission; and the support plate is fixed to the top of the base.

[0014] Furthermore, the hot air box has a rectangular box structure and is set at an angle, while the dust filter is set horizontally and close to the box cover.

[0015] Furthermore, the electric heating mesh is horizontally positioned below the dust filter and at the top of the air outlet duct, and the bottom of the hot air box is tightly fitted with the top of the drying cylinder.

[0016] Furthermore, a feed pipe is connected to the top of the drying cylinder, and a discharge pipe is connected to the bottom of the drying cylinder.

[0017] The plastic granule drying device proposed in this utility model has the following advantages:

[0018] 1. This utility model uses an inclined drying cylinder with a rotating rod and spiral turning blades installed inside. During the drying process of plastic granules, a servo motor drives the drive gear to rotate, which in turn drives the driven gear to rotate. This causes the rotating rod and spiral turning blades to rotate inside the drying cylinder, continuously turning the plastic granules spirally. Simultaneously, hot air, heated by an electric heating mesh and filtered by a dust filter, enters the drying cylinder to dry the plastic granules. This continuous upward spiral turning of the granules increases the drying time. Furthermore, the servo motor drives the drive gear to rotate in the opposite direction, which in turn drives the driven gear, rotating rod, and spiral turning blades to rotate in the opposite direction, thus accelerating the discharge speed of the plastic granules from the drying cylinder.

[0019] 2. This utility model has chip discharge holes evenly arranged at the bottom of the drying cylinder. During the process of the plastic granules being turned over by the spiral turning blades inside the drying cylinder, the small chips produced will fall from the chip discharge holes, reducing the small chips mixed in with the plastic granules and improving the quality of the plastic granules.

A support leg 3 is fixed to the top of the base 1, and a connecting plate 5 is fixed to the top of the support leg 3. A drying cylinder 6 is installed on the side of the connecting plate 5. A cylinder cover 11 is installed at one end of the drying cylinder 6. A first bolt 18 is connected between the surface of the cylinder cover 11 and the end face of the drying cylinder 6.

[0029] The top of the drying cylinder 6 has an air inlet 17, and a hot air box 9 is installed at the top of the cylinder. An air outlet pipe 24 is fixed at the bottom of the hot air box 9. The air outlet pipe 24 is inserted into the air inlet 17. Second bolts 10 are connected between the bottom ends of both sides of the hot air box 9 and the top of the drying cylinder 6.

[0030] By tilting the drying cylinder 6 and rotating the rotating rod 20 and the spiral turning blade 19 inside the drying cylinder 6, the servo motor 15 drives the drive gear 16 to rotate during the drying process of the plastic granules entering the drying cylinder 6, and the drive gear 13 is driven to rotate through the meshing transmission. This causes the rotating rod 20 and the spiral turning blade 19 to rotate inside the drying cylinder 6 and continuously turn the plastic granules in a spiral.

[0031] Meanwhile, the hot air, heated by the electric heating mesh 23 and filtered by the dust filter mesh 22, enters the drying cylinder 6 to dry the plastic granules. This allows the plastic granules to be continuously spiraled upwards during drying, increasing the drying time. Furthermore, the servo motor 15 drives the drive gear 16 to rotate in the opposite direction, which in turn drives the driven gear 13, the rotating rod 20, and the spiral turning blades 19 to rotate in the opposite direction, thereby facilitating faster discharge of plastic granules from the drying cylinder 6.

[0032] The top of the hot air box 9 is connected to a box cover 8. The top of the inside of the hot air box 9 is connected to a dust filter screen 22. The bottom of the inside of the hot air box 9 is fixed with an electric heating screen 23. The top of the base 1 is equipped with a blower 2. The top of the blower 2 is connected to a blower pipe 4.

[0033] The base 1 is horizontally positioned, the support leg 3 is vertically positioned, the connecting plate 5 is horizontally positioned, and the drying cylinder 6 is inclined, with a rectangular structure on the outside and a circular cylinder structure on the inside.

[0034] The rotating rod 20 is inclined and rotates through the cylinder cover 11. The driven gear 13 and the driving gear 16 are both inclined and mesh with each other for transmission. The support plate 14 is fixed to the top of the base 1.

[0035] The hot air box 9 has a rectangular box structure and is set at an angle. The dust filter 22 is set horizontally and close to the box cover 8.

[0036] The electric heating mesh 23 is horizontally positioned below the dust filter mesh 22 and at the top of the air outlet duct 24. The bottom of the hot air box 9 is tightly fitted with the top of the drying cylinder 6.

[0038] Example 2

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The figure shows a plastic pellet drying device for plastic production, including a base 1. A support leg 3 is fixed to the top of the base 1, and a connecting plate 5 is fixed to the top of the support leg 3. A drying cylinder 6 is installed on the side of the connecting plate 5. A cylinder cover 11 is installed at one end of the drying cylinder 6. A first bolt 18 is connected between the surface of the cylinder cover 11 and the end face of the drying cylinder 6. A rotating rod 20 rotates through the inside of the drying cylinder 6. A spiral turning blade 19 is fixed to the surface of the rotating rod 20.

Support plates 14 are rotatably installed on both sides of the driving gear 16, and a servo motor 15 is installed at one end of each support plate 14. Chip discharge holes 21 are evenly opened at the bottom end of the drying cylinder 6.

[0040] Chip discharge holes 21 are evenly arranged at the bottom of the drying cylinder 6. During the process of the plastic pellets being turned over by the spiral turning blades 19 inside the drying cylinder 6, the small chips produced will fall from the chip discharge holes 21, reducing the small chips mixed in with the plastic pellets and improving the quality of the plastic pellets.

[0041] The top of the drying cylinder 6 has an air inlet 17, and a hot air box 9 is installed at the top of the cylinder. An air outlet pipe 24 is fixed at the bottom of the hot air box 9. The air outlet pipe 24 is inserted into the air inlet 17. Second bolts 10 are connected between the bottom ends of both sides of the hot air box 9 and the top of the drying cylinder 6.

[0042] Working method: The drying cylinder 6 is set at an inclination, and a rotating rod 20 and a spiral turning blade 19 are installed inside the drying cylinder 6. During the drying process of plastic granules entering the drying cylinder 6, the servo motor 15 drives the drive gear 16 to rotate, and meshes with the driven gear 13 to rotate, thereby driving the rotating rod 20 and the spiral turning blade 19 to rotate inside the drying cylinder 6 and continuously turn the plastic granules in a spiral.

[0043] Meanwhile, the hot air, heated by the electric heating mesh 23 and filtered by the dust filter mesh 22, enters the drying cylinder 6 to dry the plastic granules. This allows the plastic granules to be continuously spiraled upwards during drying, increasing the drying time. Furthermore, the servo motor 15 drives the drive gear 16 to rotate in the opposite direction, which in turn drives the driven gear 13, the rotating rod 20, and the spiral turning blades 19 to rotate in the opposite direction, thereby facilitating faster discharge of plastic granules from the drying cylinder 6.

[0044] Chip discharge holes 21 are evenly arranged at the bottom of the drying cylinder 6. During the process of the plastic pellets being turned over by the spiral turning blades 19 inside the drying cylinder 6, the small chips produced will fall from the chip discharge holes 21, reducing the small chips mixed in with the plastic pellets and improving the quality of the plastic pellets.
