AI Technical Summary
In existing plastic masterbatch drying devices, when too much plastic masterbatch is added at once, it accumulates at the bottom and is isolated from the hot air, resulting in uneven drying of some plastic masterbatch. Furthermore, the dried masterbatch particles are prone to agglomerate, affecting their use.
It adopts a dual drying tray structure, which distributes plastic masterbatch through a rotating shaft and a deflector plate. Combined with a hot air box and a blower, hot air is delivered. A motor-driven auger breaks up large pieces of masterbatch, controls the discharge rate, and avoids sticking.
This method achieves uniform drying of plastic masterbatch, reduces uneven drying, prevents masterbatch from clumping together, and improves drying efficiency and product quality.

Description
Technical Field

[0002] Plastic masterbatch is a concentrated color masterbatch or functional masterbatch added during the production of plastic products to give them specific properties or colors. After the plastic masterbatch is formed, it needs to undergo screening processes such as pickling to filter out impurities.
[0003] Existing processing methods mostly involve drying the plastic masterbatch using a drying device before pickling. However, this method presents the following problems in actual operation:
[0004] 1) Usually, plastic masterbatch is sent into a sealed drying tank and hot air is supplied into the tank to dry the plastic masterbatch. However, when too much plastic masterbatch is added at once, the plastic masterbatch piled at the bottom is isolated from the hot air, resulting in uneven drying of some plastic masterbatch and affecting the drying effect.
[0005] 2) After drying, the plastic masterbatch in the drying tank is discharged directly through the discharge port. However, during the evaporation of moisture from the plastic masterbatch, the masterbatch particles are prone to sticking together, forming large clumps, which affects the subsequent uniform dispersion and use.

The output of the first motor 6 can drive the dial plate 7 to rotate on the first drying tray 3 and the second drying tray 4 with the rotating shaft 5 as the center.
[0032] Both the bottom of the first drying tray 3 and the second drying tray 4 are equipped with a discharge solenoid valve 8, and the first drying tray 3 is connected to the second drying tray 4 through the discharge solenoid valve 8. A guide plate 9 is also fixedly installed in the drying tank 2, and the guide plate 9 is located below the second drying tray 4.

[0034] A hot air box 12 and an air pump 13 are fixedly installed on the outside of the drying tank 2. The hot air box 12 is connected to the air pump 13 through a pipe.

[0038] In operation, the plastic masterbatch to be dried is fed into the first drying tray 3 in the drying tank 2 through the feed pipe 10. The output shaft of the first motor 6 drives the rotating shaft 5 to rotate, causing the paddle plate 7 connected to the rotating shaft 5 to rotate around the rotating shaft 5 on the first drying tray 3, distributing the plastic masterbatch accumulated on the first drying tray 3. At the same time, the paddle plate 7 rotates around the rotating shaft 5 on the second drying tray 4, further distributing the plastic masterbatch accumulated on the second drying tray 4, thereby reducing the probability of the plastic masterbatch being isolated from the hot air and ensuring drying efficiency. During this process, the discharge solenoid valve 8 connected by an electrical signal controls the connection between the plastic masterbatch on the first drying tray 3 and the second drying tray 4. Finally, the plastic masterbatch is conveyed to the guide plate 9 through the discharge solenoid valve 8 on the second drying tray 4. The guide plate 9 guides the plastic masterbatch to one side of the discharge pipe 11, and finally through the discharge pipe 11. 1. The plastic masterbatch is discharged from the drying tank 2, thereby controlling the discharge rate of the plastic masterbatch and reducing the probability of blockage in the drying tank 2. During this process, the gas is drawn in through the hot air box 12 and heated by electric heating. The drying gas in the hot air box 12 is transported to the drying tank 2 through the air duct 14 by the air pump 13 connected by the pipeline. The plastic masterbatch distributed on the first drying tray 3 and the second drying tray 4 is heated by blowing air through the first branch pipe 15 and the second branch pipe 16, so that the plastic masterbatch is dried more thoroughly. The plastic masterbatch enters the conveying tank 18 through the feeding port 19. The output shaft of the second motor 21 drives the auger 20 to rotate. Hot air is provided to the conveying tank 18 through the third branch pipe 17 connected to the air duct 14, thereby breaking up large pieces of plastic masterbatch to avoid secondary adhesion. Finally, it is discharged from the discharge port 22.
