Anti-corrosive and flame-retardant drying box for polyester filament yarn production

Abstract

The invention provides an anti-corrosive and flame-retardant drying box for polyester filament yarn production. The drying box comprises a box body, a rotating motor, a plurality of bearing plates, apower supply and a control main board. A partition plate is connected into the lower portion of the inner side of the box body. Two baffles are connected into the positions, corresponding to an upperpartition cavity, of the inner side of the box body and divide the upper partition cavity into a first chamber, a second chamber and a third chamber. The surfaces of the two baffles are each providedwith a plurality of cooling holes. The surface of a front face plate of the box body is provided with a box door. The surface of the partition plate is provided with a rotating hole. The rotating motor is arranged in the lower partition cavity. The output end of the rotating motor is connected with a rotating shaft. The rotating shaft is vertically arranged. The bearing plates are arranged on theinner side of the second chamber and sleeve the rotating shaft. The first chamber and the third chamber are each internally provided with an electric heating fan. The air outlet end of each electric heating fan faces the corresponding baffle. The power supply is arranged in a lower partition cavity. The control main board is arranged on the inner side of the lower partition cavity and electricallyconnected with the power supply. The front face plate of the box body is provided with a control opening. The drying box is convenient to operate, low in drying cost, high in drying efficiency and good in drying effect, and raw materials for polyester filament yarn production or produced intermediate materials can be effectively dried.

Description

technical field [0001] The invention belongs to the technical field of polyester filament production, and in particular relates to an anti-corrosion and flame-retardant drying box for polyester filament production. Background technique [0002] Polyester filament is made of polyester filament. Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation. , Polyethylene terephthalate (PET), fibers made by spinning and post-processing. The so-called polyester filament is a filament with a length of more than one kilometer, and the filament is wound into a ball. [0003] Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. Due to its flame retardancy, flame-retardant polyest...
