Description

Technical Field

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

[0002] In the production process of plastic products, the drying of raw material particles is an important link. Plastic particles with too high humidity are prone to quality problems such as bubbles and deformation during processing. Therefore, drying equipment is needed to dry the plastic particles.

[0003] However, during the use of the existing plastic particle drying equipment, due to the insufficient residence time of the plastic particles in the drying box, the plastic particles are prone to incomplete drying, and thus the plastic particles cannot be dried fully and evenly, resulting in poor drying effect. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a particle drying device for plastic product processing, which effectively solves the problem that during the use of the existing particle drying device for plastic product processing, due to the insufficient residence time of the plastic particles in the drying box, the plastic particles are prone to incomplete drying, and thus the plastic particles cannot be dried fully and evenly, resulting in poor drying effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A particle drying device for plastic product processing includes a drying box, a hot air drying mechanism and a plastic particle conveying mechanism;

[0007] The hot air drying mechanism includes four conveyor belts installed in the drying box and distributed alternately at equal distances, a fan support welded to the outer wall of the lower part of one side of the drying box, a hot air blower fixedly installed on the top outer wall of the fan support through bolts, and four air diffuser covers fixedly communicated with one side of the drying box and distributed at equal distances;

Through the setting of the air purification component, the hot air sent in can be filtered and purified, so as to avoid bringing external dust into the drying box during hot air drying and polluting the internal plastic particles.

[0009] As a preferred technical solution, a box door is hinged to the front of the drying box, and a moisture exhaust fan is installed on the box door. Through the moisture exhaust fan, the moisture generated during the drying process can be quickly discharged from the drying box, improving the moisture exhaust efficiency and indirectly also being beneficial to improving the drying efficiency.

[0010] As a preferred technical solution, the plastic particle conveying mechanism includes a support seat welded to the outer wall of the top of the drying box, a conveying cylinder welded to the outer wall of the top of the support seat, a motor support welded to the side wall of the conveying cylinder, a conveying motor fixedly installed on the side wall of the motor support by bolts, a transmission shaft rotatably installed in the conveying cylinder, and a auger fixedly connected to the outer wall of the transmission shaft and located inside the conveying cylinder. Through the plastic particle conveying mechanism, the plastic particles to be dried can be fed into the drying box little by little, making the feeding more convenient.

[0011] As a preferred technical solution, one end of the top of the conveying cylinder close to the motor support is fixedly communicated with a feeding hopper, and the other end of the bottom of the conveying cylinder far from the motor support is communicated with the top of the drying box through a feeding pipe.

[0012] As a preferred technical solution, the output shaft of the conveying motor penetrates through the motor support and is coaxially connected to one end of the transmission shaft through a coupling.

[0013] As a preferred technical solution, one end of the bottom of the drying box far from the fan support is fixedly communicated with a discharging hopper, and support legs are welded to the outer walls of the four corners of the bottom of the drying box.

[0014] The beneficial effects of the present utility model are as follows:

[0015] When the plastic particle drying equipment for plastic product processing is in use, the plastic particles to be dried are fed into the drying box little by little through the plastic particle conveying mechanism. The entering plastic particles will be sequentially conveyed by the four conveyor belts in an orderly manner, thereby effectively extending the residence time of the plastic particles in the drying box. And through the cooperation of the shunt pipe and the four equally spaced air diffuser covers, the hot air sent out by the hot air blower can be evenly sent into the drying box. In this way, through the above series of operations, the plastic particles entering the drying box can be fully and evenly dried, improving the drying effect. Description of the Drawings
