Description

Technical Field

[0001] The utility model relates to the field of nylon production equipment, in particular to a raw material dehydration device used for nylon production. Background Art

[0002] In the production process of nylon pellets, the raw material nylon resin needs to be dried first to remove the internal moisture in order to ensure the quality and production efficiency of the pellets. Subsequently, the raw materials are processed into pellets of appropriate size through steps such as crushing and screening, and then mixed evenly with additives. Next, the mixed raw materials are heated and melted by a melting machine to form a flowing liquid substance, and then the impurities and unmelted particles are removed by a filter, and finally the cooling system is used to quickly cool it down and solidify it into pellets.

[0003] After searching, the publication number CN220135885U discloses a raw material dehydration device for nylon production, including a dehydration drying box, a pressure relief valve pipe is fixed on the top surface of the dehydration drying box, a heating pipe is installed inside the dehydration drying box, and multiple groups of brackets are slidably connected inside the dehydration drying box, mesh plates and grids are fixed on the surface of the brackets, and stacking rings and pulleys are fixed on the bottom surface of the brackets.

[0004] Hot air circulation ovens generally blow hot air from the side of the box body to the other side to form a circulation. However, due to the design limitations of the material frame, the material frame has only an opening on the top, resulting in poor air flow in the material frame. In particular, the nylon particles inside and at the bottom of the material frame are difficult to be evenly dried. The nylon particles in the material frame are tightly packed. Although the top opening allows hot air to enter, due to the limitation of the internal space of the material frame, it is difficult for the hot air to fully penetrate to the bottom and inside of the material frame, resulting in the nylon particles on the inner surface of the material frame being dehydrated and dried first, while the nylon particles inside and at the bottom are poorly dried due to lack of sufficient hot air contact, which reduces drying efficiency and increases energy consumption.
