Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle processing, and specifically relates to a plastic pelletizer drying device. Background Art

[0002] After the plastic pellets are formed and pelletized, they need to be dried in time to remove moisture from the pellets through drying and heating, which helps to improve the quality and stability of the plastic pellets. Removing moisture can reduce the generation of bubbles in the pellets during subsequent processing, while improving their physical properties and chemical stability, ensuring that the final product meets the required quality standards.

[0003] In the existing drying equipment for plastic particles, the process time from the plastic particles entering the drying box to being discharged is relatively short, and the temperature inside the drying box is not enough to dry all the moisture on the plastic particles. If some plastic particles are piled up and clumped together, there will still be moisture on the surface of the plastic particles inside, which will affect the subsequent processing and also reduce the processing quality of the plastic particles. Utility Model Content

[0004] The purpose of the utility model is to provide a plastic pelletizer drying device, which can increase the contact time between plastic particles and hot air flow, and the plastic particles roll during the falling process, which can also increase the heating surface and increase the drying efficiency of the plastic particles.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 5As shown, a plastic pelletizer drying device comprises a drying box 1, the bottom end of the drying box 1 is conical, a feed pipe 2 is fixedly connected to the top of the drying box 1, a guide plate 3 is fixedly connected to the inner wall of the drying box 1, the cross section of the guide plate 3 is L-shaped, and the guide plate 3 is spirally distributed; in order to extend the falling time of the plastic particles and increase the contact time between the plastic particles and the hot air flow, a feed assembly is arranged on the top of the drying box 1, a round shell 10 is fixedly connected to the inner wall of the drying box 1 near the bottom end, a heating tube 11 is fixedly connected to the inner wall of the round shell 10, a plurality of through holes 12 are opened on the side wall of the round shell 10, an air circulation assembly is arranged on the side wall of the drying box 1, and a bracket 16 is fixedly connected to the bottom of the drying box 1.

[0023] like Figure 2 and Figure 3 As shown, the feeding assembly includes a feeding box 4 assembled on the top of the drying box 1, the bottom of the feeding box 4 is set in a cone shape, the side wall of the feeding box 4 is fixedly connected to a feeding pipe 5, the inner wall of the feeding pipe 5 is rotatably connected to a spiral blade 6, the side wall of the feeding box 4 is fixedly installed with a motor 7, the output end of the motor 7 is fixedly connected to the spiral blade 6, the side wall of the feeding pipe 5 is fixedly connected to a discharge pipe 8, and the discharge pipe 8 is connected to the feeding pipe 2.

[0024] Among them, in actual application, the user can set the speed of the motor 7 according to the needs to control the feeding speed of the spiral blade 6 to the plastic particles; and in the application of this scheme, it can be set on one side of the pelletizing equipment. After the pelletizing is completed, the plastic particles can be directly transported to the feed box 4 for timely drying treatment to achieve the purpose of rapid production.

[0025] like Figure 1 and Figure 2 As shown, the air circulation component includes a fan 13 mounted on the side wall of the drying box 1, and the air outlet end of the fan 13 is fixedly connected to an air outlet pipe 14, the air outlet pipe 14 runs through the drying box 1 and is connected to the circular shell 10, and the air inlet end of the fan 13 is fixedly connected to an air inlet pipe 15, and the other end of the air inlet pipe 15 extends to the top of the drying box 1 and is connected thereto.

[0026] Specifically, by setting up an air circulation component, the hot air flow inside the drying box 1 can be easily circulated. On the one hand, the energy consumption of the heating tube 11 is reduced, and at the same time, the deformation or melting of the plastic particles caused by excessive temperature can be avoided. On the other hand, the balance of the hot air flow is ensured. The air inlet position is on the round shell 10, and the direction is toward the guide plate 3. The air outlet position is located at the top of the drying box 1, so that the lower air flow can easily flow upward and bring out water vapor or moisture.

[0027] like Figure 4 As shown, the side wall of the guide plate 3 is provided with a plurality of circular holes 17. The circular holes 17 are provided to increase the air permeability of the guide plate 3, so that the airflow can enter the inner side of the guide plate 3 during the falling process of the plastic particles, so as to achieve the purpose of rapid drying, which is beneficial to improve the fluidity of the hot airflow inside the drying box 1.

[0028] like Figure 1 and Figure 2 As shown, a cover plate 9 is provided on the top of the feed box 4, and a handle is fixedly connected to the top surface of the cover plate 9.

[0029] When a large number of plastic particles need to be dried at one time, the plastic particles can be put into the feed box 4 and sealed with a cover plate 9 to prevent dust and impurities from entering the external environment during the drying process and affecting the surface cleanliness of the plastic particles.

[0030] The working principle of the utility model is as follows: first, the plastic particles after cooling and pelletizing can be introduced into the feed box 4. At this time, the fan 13 and the heating tube 11 are started. The fan 13 conveys the hot air flow in the drying box 1 to the air outlet 14, and recirculates to the inside of the round shell 10. The heat generated by the heating tube 11 is used to form a hot air flow and blown out from the through hole 12. After the temperature inside the drying box 1 reaches the set temperature, the motor 7 is then started to drive the spiral blade 6 to rotate to convey the plastic particles. The plastic particles fall on the guide plate 3 through the feed pipe 2. The plastic particles can fall with the spiral downward. During the falling process, the hot air flow is blown out in the direction of the guide plate 3 to evenly dry the plastic particles, prolong the contact time between the plastic particles and the hot air flow, and ensure that the surface of the plastic particles is in a dry state after being discharged.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
