Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic pellet drying, and more specifically, to a raw material drying device for plastic pellet production. Background Art

After the masterbatch enters the drying equipment, it enters multiple guide plates in a graded manner. By improving the flow path of the masterbatch, the effective drying time of the masterbatch is increased. However, plastic particles tend to accumulate in large quantities when wet, causing the plastic particles to squeeze each other, making the plastic particles stick to each other, making them unable to disperse after drying, and the masterbatch falls directly along the guide plate, with a fast flow rate, affecting the drying time, resulting in poor drying effect.

[0025] Further, such as Figure 1As shown, the drying device also includes a plurality of guide plates 2, a vibrating member 3 and a hot air conveying assembly 4; wherein the plurality of guide plates 2 are arranged obliquely from top to bottom in the drying box 1, and the bottom end of the upper guide plate 2 is located above the top end of the lower guide plate 2, so that the plurality of guide plates 2 form a plastic pellet conveying path, which facilitates the plastic pellets to roll through each guide plate 2 in turn for guiding and heat dissipation; the vibrating member 3 is installed in the drying box 1 and connected to the guide plate 2, and is used to drive the guide plate 2 to vibrate, thereby avoiding the accumulation of plastic pellets on the guide plate 2, and ensuring that the plastic pellets The hot air conveying assembly 4 comprises a hot air blower 41 and a plurality of air outlet nozzles 42 connected to the output end of the hot air blower 41; each air outlet nozzle 42 is respectively installed in the drying box 1, and points to the bottom end of each guide plate one by one, so as to blow the hot air from the bottom end to the top end of the guide plate, so that the wind direction of the hot air is opposite to the falling direction of the plastic particles, which is convenient for slowing down the falling speed of the plastic particles, ensuring the drying time of the plastic particles, and being able to blow the rolling plastic particles comprehensively to improve the drying effect.
[0026] like Figure 2 and Figure 3 As shown, in order to improve the evacuation effect of the plastic particles on the guide plate, a plurality of guide channels 21 for conveying the plastic particles are evenly arrayed on the surface of the guide plate, so that the plastic particles can be arranged and dried along each guide channel 21 on the guide plate, which is convenient for uniform arrangement and reduces the accumulation of plastic particles.
[0027] Furthermore, an S-shaped arrangement is formed between the connection of two adjacent guide channels 21 and the guide channels 21 to guide the plastic particles to fall into the guide channels 21; at the same time, the spacing between two adjacent guide channels 21 is smaller than the diameter of the plastic particles, so that the plastic particles can fall into the guide channels 21 along the S-shaped structure and fall evenly, thereby improving the uniformity of the dispersion and drying of the plastic particles, reducing the accumulation of plastic particles, and thereby improving the drying effect.
[0028] In some embodiments, Figure 1 and Figure 2 As shown, in order to facilitate the vibration of the guide plate 2, a guide groove 11 is provided on the inner wall of the drying box 1 for the guide plate 2 to reciprocate in the horizontal direction; the vibrating member 3 is installed on one side of the guide groove 11; the other side of the guide groove 11 is installed with an elastic member 6 connected to the guide plate 2, so that the vibrating member 3 drives the guide plate 2 to reciprocate in the horizontal direction, and cooperates with the elastic member 6 to facilitate the vibration reset of the guide plate 2, thereby improving the vibration effect. Furthermore, a guide column 12 is installed in the guide groove 11; the guide column 12 passes through the top of the guide plate 2, so that the guide plate 2 can move along the guide column 12; the elastic member 6 is a reciprocating spring sleeved on the guide column 12; the guide plate 2 is guided to move by the guide column 12, and the elastic member 6 is sleeved, so as to facilitate the improvement of the horizontal vibration stability of the guide plate 2, and then facilitate the dispersion of the plastic particles on the guide plate 2 to prevent the accumulation of plastic particles.
[0029] In this embodiment, the vibrating element 3 is a vibration motor, which is convenient to use after being powered on, thereby improving the convenience of use.
[0030] In some embodiments, Figure 1 As shown, in order to facilitate the discharge of water vapor generated by drying, a plurality of exhaust fans 5 are installed on the side wall of the drying box 1, and each exhaust fan 5 is respectively directed toward the top of each guide plate to discharge the air flow with water vapor, thereby preventing the water vapor generated by the drying of the plastic particles on the guide plate from flowing upward and affecting the drying effect of the plastic particles above.
[0031] Furthermore, a heat conduction cavity 15 is formed in the inner wall of the drying box body 1; the air outlets of each of the exhaust fans 5 are connected to the heat conduction cavity 15 to send the recovered hot air into the heat conduction cavity 15, thereby ensuring the internal temperature of the drying box body 1 and saving heat energy loss; further, a filter element 16 is arranged in the heat conduction cavity 15, and an exhaust port 17 is arranged at the top of the heat conduction cavity 15, so that the recovered hot air can be discharged from the exhaust port 17 after being filtered by the filter element 16. The filter element 16 can be arranged in combination with activated carbon and cooling water. On the one hand, impurities are filtered by the activated carbon, and on the other hand, the airflow is cooled by the cooling water and then sent out, so as to prevent the temperature of the factory from being too high.
[0032] In some embodiments, Figure 1 As shown, the bottom of the drying box 1 is provided with a discharge port 14 and an inclined surface 13 inclined downward toward the discharge port 14; the output end of the hot air blower 41 is also connected to a feeding air outlet terminal 43; the feeding air outlet terminal 43 is installed on the inner wall of the drying box and aligned with the discharge port 14 of the inclined surface 13, so that the plastic particles that have fallen and dried after passing through the guide plate can be quickly sent to the discharge port 14 for delivery, and avoid being accumulated at the bottom of the drying box 1. At the same time, the plastic particles delivered from the discharge port 14 can be circulated into the drying box 1 through the circulatory feeding mechanism 10 for drying, and the drying is circulated for multiple times until the completely dried plastic particles are discharged through the discharge port 14, thereby improving the drying effect.
[0033] The embodiment of the present application discloses a raw material drying device for the production of plastic pellets, which can guide the plastic pellets to roll and fall through the guide plate 2, and vibrate with the vibrating member 3, so that the plastic pellets are evenly dispersed in each guide channel 21 of the guide plate 2, thereby avoiding the accumulation or uneven distribution of the plastic pellets on the guide plate 2. When the hot air blower 41 is used to blow hot air to each guide plate 2 one by one, the plastic pellets can be evenly dried by the hot air, and the accumulated plastic pellets cannot be dried by the wind. At the same time, the falling speed of the plastic pellets on the guide plate can be slowed down to ensure that the plastic pellets are uniformly dried. Comprehensive drying improves the drying effect; the plastic pellets that fall to the bottom of the drying box 1 are discharged through the feeding outlet end 43 at the bottom, so that the hot air blows the plastic pellets toward the discharge port 14, which is not only convenient and quick to discharge, but also can be further dried with the hot air, further improving the drying effect; the plastic pellets that enter the discharge port 14 can be circulated and sent into the drying box 1 again through the circulating feeding mechanism 10 for drying, until the plastic pellets are completely dried, the circulating feeding mechanism 10 is shut down and the discharge port 14 is opened, so that the plastic pellets are sent out through the discharge port 14, completing the entire drying operation. Through this solution, the accumulation of plastic pellets can be prevented during the drying process, and the contact time between the plastic pellets and the hot air can be increased, thereby achieving the advantages of increasing the drying speed and drying effect.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
