CN224004111U - Raw material drying equipment for PET (polyethylene terephthalate) photovoltaic backboard film processing - Google Patents

Abstract

This utility model discloses a raw material drying device for PET photovoltaic backsheet film processing, aiming to solve the problem that in existing drying equipment, raw materials are mostly piled up together, which leads to uneven heating of the raw materials on the inside and outside of the pile, and the raw materials on the inside are more difficult to dry, resulting in low drying efficiency. This utility model sets the drying drum into a sideways cylindrical shape, and then sets multiple buckets that circulate around the inner cavity of the drying drum. The buckets are equipped with several holes. The buckets scoop up the raw materials, and as the raw materials move with the buckets, they are gradually sprinkled down through the multiple holes, which disperses the raw materials and increases the contact area between the raw material particles and the hot air in the inner cavity, making the raw material particles more evenly heated. Several rotating transport buckets are also rotatably connected to the drying drum. Workers only need to pour the raw materials to be dried into the transport buckets, and the transport buckets will send the raw materials into the feed inlet, making the feeding more convenient.
