Description

Technical Field

[0001] This utility model relates to the field of drying, and more specifically, it relates to a raw material drying device for processing PET photovoltaic backsheet film. Background Technology

[0002] PET photovoltaic backsheet film is a material specifically used for the protection of the back of solar photovoltaic modules. Its main functions are to provide electrical insulation, waterproofing, moisture protection, and resistance to ultraviolet aging. Due to the hygroscopic nature of PET, PET raw materials may become damp during transportation and storage. To ensure the quality of the finished PET photovoltaic backsheet film, the damp raw materials are dried. Existing drying equipment dries the raw materials by means of hot air or electric heating wire. However, in existing drying equipment, the raw materials are mostly piled together, which leads to uneven heating of the raw materials on the inside and outside of the pile. The raw materials on the inside are more difficult to dry, resulting in low drying efficiency.

[0003] Based on the above, the purpose of this utility model is to provide a raw material drying equipment for PET photovoltaic backsheet film processing, so as to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a raw material drying device for PET photovoltaic backsheet film processing. This invention involves setting the drying drum into a sideways cylindrical shape, and then setting multiple buckets that circulate and move around the inner cavity of the drying drum. Each bucket has several perforations. The buckets scoop up the raw materials, and as the raw materials move with the buckets, they gradually fall downwards through the multiple perforations, causing the raw materials to disperse and increasing the contact area between the raw material particles and the hot air in the inner cavity, thus making the raw material particles heat more evenly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a raw material drying device for PET photovoltaic backsheet film processing, including a support frame, a drying barrel is provided on the support frame, the drying barrel is provided with a feed inlet, a discharge pipe and a heater, the drying barrel is a side-lying cylinder, the support frame is provided with a rotating shaft and a drive mechanism for driving the rotating shaft to rotate, the rotating shaft passes through the center of the drying barrel, and a plurality of support rods are provided on the part of the rotating shaft located inside the drying barrel, one end of which is fixedly connected to the support rod, and the other end of the support rod is fixedly connected to a bucket, the bucket being provided with a plurality of drainage holes.

[0006] By adopting the above technical solution, when PET raw materials need to be dried, the raw materials are poured into the drying drum through the feed inlet, and then the temperature inside the drying drum is raised by the heater to dry the raw materials. During this process, the drive mechanism drives the rotating shaft to rotate, and the rotating shaft will drive the bucket to circulate inside the drying drum. With this setting, the bucket will scoop up the raw materials, and the raw materials will gradually fall down through multiple holes as they move with the bucket. This not only prevents the raw materials from accumulating and making it difficult for the internal raw materials to be heated, but also disperses the raw materials, increases the contact area between the raw material particles and the hot air inside the cavity, and makes the raw material particles heat more evenly.

[0007] The present invention is further configured such that: an installation ring is rotatably connected to the outer wall of the drying drum, a plurality of transport buckets are fixedly connected to the installation ring, and a transport mechanism for driving the installation ring to rotate is provided on the support frame.

[0008] The present invention is further configured such that: the conveying mechanism includes a plurality of connecting rods, one end of which is fixedly connected to the rotating shaft, and the other end of the connecting rod is fixedly connected to the mounting ring.

[0009] The present invention is further configured such that: the driving mechanism includes a motor fixedly connected to the support frame, and a belt pulley transmission assembly is provided between the motor and the rotating shaft.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This invention features a drying drum shaped like a sideways cylinder, with multiple buckets circulating around its inner cavity. Each bucket has several perforations. The buckets scoop up the raw material, which then gradually falls through the perforations as it moves, spreading out the material and increasing the contact area between the raw material particles and the hot air inside the cavity, resulting in more even heating. Several rotating transport buckets are also connected to the drying drum. Workers simply pour the raw material to be dried into the transport buckets, which then deliver it to the feed inlet, making loading more convenient. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A raw material drying device for processing PET photovoltaic backsheet film, such as Figure 1-2 As shown, the device includes a support frame 1, on which a drying drum 2 is fixedly connected. The drying drum 2 is provided with an inlet 3, an outlet pipe 4, and a heater 5. A valve is installed on the outlet pipe. The heater is one or more of an electric heating wire and a hot air blower. The electric heating wire is embedded in the inner wall of the drying drum. The hot air blower can be installed on the side of the drying drum or on the support frame. Several ventilation slots connected to the hot air blower are opened on the side wall of the drying drum. The drying drum 2 is a cylindrical shape lying on its side. A rotating shaft 6 and a drive mechanism for driving the rotating shaft 6 to rotate are rotatably connected to the support frame 1. The rotating shaft 6 passes through the center of the drying drum 2. Several support rods 7 are provided on the part of the rotating shaft 6 located inside the drying drum 2, with one end fixedly connected to it. The other end of the support rod 7 is fixedly connected to a bucket 8, and several drainage holes 9 are opened on the bucket 8.

[0020] Furthermore, an installation ring 10 is rotatably connected to the circular outer wall of the drying drum 2, and several transport buckets 11 are fixedly connected to the installation ring 10. The transport buckets and the digging buckets are staggered. The support frame 1 is equipped with a handling mechanism that drives the installation ring 10 to rotate.

[0021] Furthermore, the conveying mechanism includes several connecting rods 12, one end of which is fixedly connected to the rotating shaft 6, and the other end of the connecting rod 12 is fixedly connected to the mounting ring 10.

[0022] Furthermore, the drive mechanism includes a motor 13 fixedly connected to the support frame 1. A belt pulley transmission assembly 14 is installed between the motor 13 and the rotating shaft 6. The belt pulley transmission assembly includes two pulleys fixedly connected to the motor output shaft and the rotating shaft respectively, and several transmission belts are sleeved between the two pulleys.

[0023] Working principle: When PET raw materials need to be dried, the worker pours the raw materials into the conveyor hopper. Then, the temperature of the inner cavity of the drying drum 2 is raised by the heater 5. The rotating shaft 6 is driven to rotate by the motor 13 and the belt pulley transmission assembly 14. The rotating shaft 6 will drive multiple conveyor hoppers and digging buckets 8 to rotate. The rotating conveyor hoppers will carry the raw materials up until the raw materials slide through the feed inlet 3 and enter the inner cavity of the drying drum 2 due to inertia. The rotating digging buckets 8 will scoop up the raw materials. As the raw materials move with the digging buckets 8, they will gradually fall down through multiple holes 9. This prevents the raw materials from piling up and making it difficult for the internal raw materials to be heated. It also disperses the raw materials, increases the contact area between the raw material particles and the hot air in the inner cavity, and makes the raw material particles heat more evenly.
