Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass fiber reinforced plastic recycling, and particularly relates to a glass fiber reinforced plastic product production recycling device and method thereof. BACKGROUND

[0002] Glass fiber reinforced plastic (GFRP) as a kind of excellent performance composite material, has been widely used in aerospace, automobile manufacturing, building materials and many other fields. With the increasing application amount, the waste of GFRP products after reaching the service life is also increasing. If these wastes are not properly treated, not only the resources will be wasted, but also the environment will be seriously polluted. Therefore, it is of great practical significance to efficiently recycle the glass fiber reinforced plastic products.

[0003] In the existing glass fiber reinforced plastic product recycling process, drying and screening are two key links. In the drying link, the traditional drying equipment usually adopts a single heating method, such as electric heating or hot air direct blowing. However, these methods have many shortcomings. The electric heating method has high energy consumption, which increases the recycling cost; and the hot air direct blowing method is difficult to achieve uniform and efficient drying for the fibrous materials, especially the recycled materials of glass fiber reinforced plastic products. The materials are prone to clumping during the drying process, which makes it difficult to completely remove the moisture, affecting the efficiency and product quality of subsequent processing.

[0004] In the screening link, the fiber fragments in the glass fiber reinforced plastic recycled materials are prone to block the screen mesh. The traditional screening equipment has low screening efficiency when processing such materials, and needs to be frequently stopped for cleaning the screen, which not only reduces the production efficiency, but also increases the labor cost. Moreover, for the coarse materials that have not been screened, the traditional equipment lacks effective automatic recycling crushing mechanism, and often needs to manually take out and re-feed the coarse materials into the crushing equipment, which is tedious and has low automation degree. Therefore, it is necessary to design a glass fiber reinforced plastic product production recycling device and method thereof. SUMMARY
