Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nylon chip drying, in particular to a nylon chip drying device. BACKGROUND

[0002] The nylon chip drying device is mainly used for removing water in nylon chips (i.e. nylon chips) in the production process to meet the drying standard suitable for subsequent processing, and the nylon is a synthetic fiber material widely used in the fields of textiles, carpets, automobiles, shoes, etc. In the production process of nylon, chips or particles with water are usually generated, which will affect the subsequent processing process, such as melt spinning, stretching, dyeing, etc. Therefore, effective drying treatment is required. The nylon chip usually contains a certain amount of water after forming, and the water content is usually required to be controlled between 0.1% and 0.3%, which is crucial to ensure the quality of the nylon product. Too high water content will cause bubbles, broken wires or other processing problems during melt processing, while too low water content will increase the brittleness of the raw material, affecting its subsequent processability.

[0003] As disclosed in the patent CN111854364A, a continuous drying device for nylon wet chips is disclosed, the inside of the box is provided with a partition plate, and the gap between the inside bottom end of the box and the partition plate forms a water draining layer. An inner container is fixed on the upper position of the partition plate in the inside of the box, and the gap between the inside of the box and the outside of the inner container forms a heat preservation cavity. A first speed regulating motor is installed on the upper center position of the box. The present application has novel design and simple structure. The annular hot air mechanism can realize full-area hot air circulation sweeping without dead angle, improve the overall air flow rate, so that any surface of the nylon wet chip can be swept by hot air, accelerate the drying speed, and the material circulating and turning mechanism can transport the bottom nylon wet chip upward and then discharge it from the discharge pipe. The discharged material can be swept by hot air again in the air, which shortens the drying time, improves the drying effect, and avoids the problem of insufficient drying of the bottom accumulated nylon wet chips.

[0004] Although the above-mentioned patent can achieve a certain degree of drying treatment, the hot air mechanism of the device has the problem of high energy consumption, lacks an effective waste heat recovery mechanism, and a large amount of heat energy is wasted, which fails to fully utilize the generated heat, thereby reducing the overall energy utilization efficiency.
