Description

Technical Field

[0001] This utility model relates to the field of plastic particle cooling technology, specifically to a plastic particle noise reduction and cooling device. Background Technology

[0002] In the existing plastic granulation industry, granulated plastic granules are directly transported to the packaging station via dilute phase transport. Specifically, in existing technology, several cyclone separators (each equipped with a medium-pressure blower to convey the plastic granules) are connected by pipelines. When the hot plastic granules from the first cyclone separator are conveyed to the second cyclone separator, the cooling and conveying of the plastic granules is completed. Then, the medium-temperature plastic granules from the second cyclone separator continue to be conveyed to the third cyclone separator (at which point they arrive at the packaging station and are put into packaging bags).

[0003] Thus, during the process of conveying plastic granules through the cyclone bucket, some plastic granules may not be sufficiently cooled. Direct packaging can easily cause the plastic to clump together in the packaging bag, which is not conducive to factory storage. Utility Model Content

[0055] In this embodiment, the operator can add plastic granules into the screen cylinder 4 through the feeding hopper 2. Then, the operator can introduce air into the first air inlet pipe 7 and the blower pipe 9 through the second air inlet pipe 8, and simultaneously blow air onto the plastic granules through the blower nozzle. This cooling of the plastic granules is achieved through heat exchange between the air and the plastic granules. During the air cooling process, the operator controls the first motor 12 to operate. The operation of the first motor 12 drives the first gear 11 to rotate. Simultaneously, the meshing of the first gear 11 with the first gear ring 10 drives the first air inlet pipe 7 to rotate, thereby adjusting the position of the blower nozzle and improving cooling efficiency. At the same time, the rotation of the first air inlet pipe 7 drives the first bevel gear 13 to rotate around the second bevel gear 15. The meshing of the second bevel gear 15 with the first bevel gear 13 drives the first bevel gear 13 and the blower pipe 9 to rotate, thus facilitating the rotation of the stirring rod on the blower pipe 9. 16. The plastic granules are stirred to further improve the cooling efficiency. During the air cooling process, water can be supplied to the second support housing 18 and the spray pipe 20 through the water inlet pipe 19. Water can then be sprayed onto the plastic granules through the nozzles, and the plastic granules can be cooled through heat exchange between the water and the plastic granules. At the same time, the operator controls the second motor 24 to work. The operation of the second motor 24 can drive the drive rod and the third bevel gear to rotate. Simultaneously, the meshing of the third bevel gear with the second gear ring 22 and the meshing of the second gear 21 with the second gear ring 22 drives multiple second gears 21 and multiple spray pipes 20 to rotate, thereby adjusting the spray angle of the nozzles to improve the uniformity of the spray and further improve the water cooling efficiency of the plastic granules. After the plastic granules have cooled, the operator opens the discharge control valve, so that the plastic granules can be discharged from the screen cylinder 4 through the discharge port 5.
