Technical Field

[0001] The utility model relates to the technical field of plastics, in particular to a drying device for processing plastic particles. Background Art

[0002] Plastics are macromolecules made from monomers through polyaddition or condensation reactions. Microplastics can harm human health. Their deformation resistance is moderate, between that of fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] After searching, Chinese patent application No. 202222475711.7 discloses a drying device for processing plastic particles, comprising a box body, the inner bottom wall of the box body is fixedly connected to a drive motor, the output end of the drive motor is fixedly connected to a bracket, a rotating net is provided inside the bracket, a plurality of first sliders are fixedly connected to the outer surface of the bracket, the inner wall of the box body is fixedly connected to a circular hole clamp, and the inner ring of the circular hole clamp is provided with a first slide groove. This drying device for processing plastic particles, through the cooperation of the drive motor on the inner bottom wall of the box body and the bracket, causes the bracket to drive the rotating net to rotate, and the moisture on the plastic particles placed in the rotating net is thrown out, so that the moisture on the surface of the plastic particles is reduced.

[0024] As a technical optimization solution of the present invention, through the coordinated use of the fan 12 and the air outlet slot 13, the wind force generated when the fan 12 is started can accelerate the heat generated by the heating tube 8 and the heating rod 7 to be dissipated to the interior of the drying cylinder 5, thereby improving the drying effect. By setting the filter 14, a blocking effect is played on the plastic particles, thereby preventing the plastic particles from entering the interior of the heating cylinder 6 and affecting the normal use of the device.

[0026] As a technical optimization solution of the present invention, by setting up the coordinated use of the electric telescopic rod 15, the second bracket 16 and the rotating shaft, the electric telescopic rod 15 can be started to extend when discharging, thereby raising the height of the left side of the drying cylinder 5, so that the plastic particles can be easily discharged from the first material pipe 10 and the second material pipe 11, which is convenient for users to use.

[0027] refer to Figure 2 The left and right sides of the top of the bottom plate 1 are fixedly connected with support brackets 18.

[0032] As a technical optimization solution of the present invention, by setting up a shock-absorbing plate 22, the vibration generated during the operation of the device can be absorbed and weakened, the resonance of the device can be reduced, and the operation can be smoother. By setting up an anti-slip groove 23, the friction between the bottom of the device and the ground is increased, avoiding the situation where the device shakes and moves during use, affecting the drying effect.

[0033] The working principle and usage process of the present invention are as follows: plastic particles of different sizes are added into the interior of the drying box through the second material pipe 11, and then the driving motor 4, the heating rod 7 and the heating tube 8 are started. The starting of the driving motor 4 drives the drying cylinder 5 to rotate, and the heating rod 7 and the heating tube 8 are used to heat the interior of the drying cylinder 5. When the drying cylinder 5 rotates, the plastic particles inside it follow the rotation, thereby accelerating the drying.
