Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and specifically discloses a drying device for recycled plastic granules. Background Technology
[0002] Recycled plastic pellets have a wide range of applications. In agriculture, they can be used to make agricultural films, water pipes, agricultural machinery, fertilizer bags, and cement bags. Furthermore, recycled pellets are widely used in the electrical and telecommunications industries. However, recycled plastic pellets are easily exposed to moisture. Plastic products made from damp recycled plastic pellets will have significantly reduced chemical properties, affecting product quality. Therefore, loose recycled plastic pellets need to be dried before being processed into plastic products.
[0003] Traditional drying equipment generally suffers from insufficient heating of materials, resulting in low drying efficiency and high energy consumption. Furthermore, existing equipment often employs simple spreading or static drying methods, which easily leads to particle accumulation and clumping, affecting drying uniformity and potentially causing plastic particle denaturation due to localized overheating. Therefore, a drying device for recycled plastic particles is needed to solve this problem. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0022] Please see Figure 1-4 A drying device for recycled plastic granules includes a box body 1, a hopper 2 is provided on the upper end face of the box body 1, a material leveling mechanism and a drying mechanism are provided inside the box body 1, the material leveling mechanism includes a feeding cylinder 3 fixedly connected between the front and rear end faces inside the box body 1 and communicating with the hopper 2, the lower end face of the feeding cylinder 3 is provided with a strip-shaped discharge port 4 arranged along its length direction, a drive motor 5 is installed on the outer wall of the box body 1, the output end of the drive motor 5 extends into the interior of the feeding cylinder 3 and is fixedly connected to a rotating shaft 6, and a spiral blade 7 is fixedly connected to the outer wall of the rotating shaft 6;
[0023] The drying mechanism includes multiple hot air blowers 8 installed on the upper surface of the box 1 and connected to the air outlet of the box 1. A vibrating plate 9 is installed inside the box 1. Multiple evenly distributed screen holes 13 are opened on one side of the vibrating plate 9. A receiving plate 12 located below the screen holes 13 is fixedly connected to the lower end of the vibrating plate 9 by bolts. One side of both the vibrating plate 9 and the receiving plate 12 extends to the outside of the box 1 and is provided with a discharge port.
[0024] In this embodiment: plastic granules are poured into hopper 2 and flow downwards into feed cylinder 3. Drive motor 5 is started, which drives shaft 6 to rotate, thereby driving spiral blades 7 to rotate. This causes the plastic granules in feed cylinder 3 to move to both ends and fall evenly downwards onto vibrating plate 9 through strip-shaped discharge port 4. Vibration of vibrating plate 9 disperses clumps of plastic granules, which then move to the other side of vibrating plate 9. Hot air is blown out by multiple hot air blowers 8 to dry the plastic granules. Qualified plastic granules fall into receiving tray 12 through sieve holes 13 and are discharged through discharge port. Clumps of plastic granules are filtered onto vibrating plate 9 and discharged through discharge port for collection and further processing. This utility model, through the uniform material distribution mechanism and drying mechanism, allows the plastic granules to fully contact the hot air, resulting in uniform drying of the plastic granules. It can also screen clumps of plastic granules, resulting in good performance.
[0025] As a technical optimization of this utility model, elastic components 11 are provided at the four corners of the lower end face of the vibratory plate 9 and between the lower end face inside the box 1, and a vibration motor 10 is installed on the lower end face of the vibratory plate 9.
[0026] In this embodiment: the vibration motor 10 is started, and the vibration motor 10 drives the vibratory plate 9 to vibrate under the action of the elastic component 11, so as to convey and disperse the plastic particles.
[0027] As a technical optimization of this utility model, a plurality of evenly distributed triangular plates 14 are fixedly connected to the upper end face of the vibratory plate 9.
[0028] In this embodiment: by fixing multiple evenly distributed triangular plates 14 to the upper end face of the vibratory plate 9, the time that the plastic particles stay on the vibratory plate 9 is increased, and the plastic particles are evenly distributed on the vibratory plate 9, so that the hot air can fully contact the plastic particles.
[0029] As a technical optimization of this utility model, the vibratory plate 9 is set at an angle.
[0030] In this embodiment, the vibratory feeder 9 is tilted to facilitate material feeding.
[0031] As a technical optimization of this utility model, the spiral directions at both ends of the spiral blade 7 are opposite.
[0032] In this embodiment, by setting the spiral directions at both ends of the spiral blade 7 to be opposite, the plastic particles can move towards both ends under the action of the spiral blade 7.
[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of the housing 1, and the drive motor 5, the hot air blower 8 and the vibration motor 10 are all electrically connected to the controller.
[0034] In this embodiment, the controller facilitates the normal operation of the drive motor 5, the hot air blower 8, and the vibration motor 10.
[0035] The working principle and usage process of this utility model are as follows: Plastic granules are poured into the hopper 2 and flow downwards into the feeding cylinder 3. Then, the drive motor 5, hot air blower 8, and vibration motor 10 are started. The drive motor 5 drives the rotating shaft 6 to rotate, which in turn drives the spiral blades 7 to rotate, causing the plastic granules in the feeding cylinder 3 to move to both ends and fall evenly downwards onto the vibrating plate 9 through the strip-shaped discharge port 4. The vibration motor 10 drives the vibrating plate 9 to vibrate under the action of the elastic component 11, breaking up any clumps of plastic granules and moving them to the other side of the vibrating plate 9. Multiple hot air blowers 8 blow hot air to dry the plastic granules. Qualified plastic granules fall through the sieve holes 13 into the receiving tray 12 and are discharged through the discharge port. Clumps of plastic granules are filtered onto the vibrating plate 9 and discharged through the discharge port for collection and further processing. This utility model, through its equalization mechanism and drying mechanism, allows the plastic granules to fully contact the hot air, resulting in uniform drying. It can also screen clumps of plastic granules, achieving good usage results.
