Description

Technical Field

[0001] This utility model relates to the field of recycled fiber production technology, and in particular to a multi-stage airflow drying device for a recycled fiber production line. Background Technology

[0002] Multi-stage airflow drying equipment for recycled fiber production lines is a device used to dry fibers during the recycled fiber production process. Based on the principle of airflow drying, it combines multiple drying structures to achieve a more efficient and uniform drying effect. It is mainly used in the recycled fiber production industry, such as the drying process of recycled polyester fiber, recycled cellulose fiber, and recycled protein fiber. In these production processes, fibers that have undergone spinning, stretching, and other processes usually contain a certain amount of moisture and need to be dried to improve their performance and quality to meet the requirements of subsequent processing and use. Multi-stage airflow drying equipment can provide efficient and high-quality drying services tailored to the characteristics of different types of recycled fibers and is one of the indispensable key pieces of equipment in recycled fiber production lines.

[0003] When workers need to dry recycled fibers, they pour the fibers into the feed inlet of the heating chamber. A fan draws hot air from the heater, which draws the recycled fibers into the first heating chamber. As the hot air continues to flow, the recycled fibers are drawn into the second heating chamber. Finally, the hot air carries the recycled fibers into the discharge cylinder. However, during the operation of existing drying equipment, the heat causes a large amount of harmful gases to be generated on the surface of the recycled fibers. The drying equipment also discharges these harmful gases along with the recycled fibers, which leads to a decrease in the air quality in the workshop. Utility Model Content

[0006] Preferably, the enclosed box is equipped with a feeding device, which includes a cylinder. The cylinder is fixedly connected to one side of the enclosed box, and a pusher plate is fixedly connected to the drive end of the cylinder. The cylinder can cooperate with the enclosed box to support the cylinder.

[0008] Preferably, the enclosed box has a material guide groove inside, and the pusher plate is slidably connected to the inner wall of the material guide groove. The material guide groove can cooperate with the enclosed box to achieve the purpose of temporarily storing materials.

[0009] Preferably, the sealed box is rotatably connected to a sealing gasket, and a limiting strip is fixedly connected to the bottom end of the sealing gasket. The limiting strip is placed on one side of the sealed box, and the sealing gasket can cooperate with the sealed box to prevent hot air from flowing out.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a filtration device, when the worker needs to deal with harmful gases, the feeding cylinder guides the material and hot air into the closed box. The worker starts the drive motor, which drives the fan blades. The fan blades rotate and draw in the gas inside the closed box. The gas passes through the cloth bag, which performs initial filtration. The gas then passes through the activated carbon plate, which deodorizes the gas.

[0012] 2. In this utility model, by setting up a feeding device, when the worker needs to feed materials, when the materials fall into the guide trough of the closed box, the baffle will prevent the materials from being sucked away by the filter device.
