Description

Technical Field

[0001] The utility model relates to the technical field of recycled plastic particle processing, in particular to a recycled plastic particle circulation drying mechanism. Background Art

[0002] Recycled plastics are the reuse of plastics. After being crushed by mechanical blades, the plastics are reused. Recycled plastics refer to plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. It is the reuse of plastics.

[0003] In the prior art, a Chinese patent with publication number "CN207894175U" discloses a rotary plastic particle drying device. By providing a spiral feeding device, the plastic particles can be dried while being sent to a drying chamber, thereby improving the drying efficiency of the plastic particles. By providing a heating device and a first heater, the drying efficiency and quality of the plastic particles are greatly improved, and the problem that the existing drying devices all dry the plastics after placing them in a centralized manner, the drying effect of the plastic particles close to the heating device is good, and the effect of the plastic particles far away from the heating device is relatively poor, which can easily cause uneven drying of the plastic and low drying efficiency.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] After plastics are processed and pelletized, a certain amount of moisture will remain on the surface of the plastic particles. If they are not dried in time, the quality of the plastics will be affected to a certain extent. When drying plastic particles, most of the plastic particles are put into a tank, and then stirred by a stirring rod, and then ventilated into the box to dry the plastic particles. However, this drying method makes it difficult for the plastic particles at the bottom of the tank to contact with the hot air flow. Although there is a stirring effect of the stirring rod, the stirring rod cannot effectively stir the plastic particles at the bottom, which will affect the drying effect of the device.

[0031] A stirring assembly is provided in the tank body 1, and the plastic particles in the tank body 1 are turned over by the stirring assembly. The stirring assembly includes a motor 6 and a driving slot 7, and the driving slot 7 is in a state of communication with the interior of the tank body 1. A stirring shaft 8 is fixedly installed at the output end of the motor 6, and a driving gear 9 and a stirring blade 10 are installed on the stirring shaft 8;

[0032] A driven gear 11 is rotatably installed inside the driving groove 7, a rotating ring 12 is rotatably installed on the inner side of the driving groove 7, a ring-shaped tooth block 13 and a toggle block 14 are fixedly installed on the inner side of the rotating ring 12, the driving gear 9 is meshed with the driven gear 11, the driven gear 11 is meshed with the tooth block 13, the driving gear 9 and the tooth block 13 are located inside the driving groove 7, and the stirring blade 10 and the toggle block 14 are located inside the tank body 1.

[0034] Embodiment 2:

[0035] On the basis of Example 1, in order to facilitate the discharge of the dried plastic particles in the tank body 1, a flip assembly is used to improve the efficiency and effect of the plastic particle discharge. A flip assembly is provided on the support plate 2, and the plastic particles in the tank body 1 can be easily discharged from the tank body 1 through the flip assembly.

The tank body 1 in the tilted state will cause the internal plastic particles to be completely discharged from the discharge port, thereby improving the practicality of the drying mechanism.

[0037] Working principle:

[0038] When in use, the feed door 24 is opened, and then the plastic particles to be dried are put into the tank body 1, and then the feed door 24 is closed again, and the hot air blower 3 is turned on, and the hot air blower 3 passes the hot air flow into the tank body 1 through the exhaust pipe, and at the same time, the stirring shaft 8 is driven by the motor 6 to rotate, and the stirring shaft 8 drives the stirring blades 10 to stir the plastic particles in the tank body 1 when rotating.

The moving block 19 moves on the inclined block 16 during movement. Through the action of the inclined block 16, the tank body 1 will change state through the connecting block 21, so that the tank body 1 is in an inclined state. The tank body 1 in an inclined state will cause all the plastic particles inside to be discharged from the discharge port, thereby improving the practicality of the drying mechanism.
