AI Technical Summary

Technical Problem

Existing methods of spraying flame retardants result in uneven distribution of the flame retardant on polyester filaments, with some areas being too thick or too thin, affecting product consistency and quality.

Method used

The system employs a mixing and spraying assembly within the spray box. The flame retardant is uniformly mixed using stirring blades. The reciprocating oscillation of the nozzle and the assistance of the brush ensure that the flame retardant is evenly distributed on the polyester filaments. The flame retardant is then recycled through a filter plate and a circulating pump.

Benefits of technology

It improves the uniformity of flame retardant distribution on polyester filament, enhances the consistency of flame retardant effect, increases the contact area between polyester filament and flame retardant, improves the coating effect and reduces production costs.

Abstract

The application discloses a production device of flame-retardant polyester filaments and relates to the technical field of flame-retardant polyester production and preparation. The application comprises a spraying box, one side of the spraying box is fixedly connected with a liquid storage tank, a plurality of feeding ports are evenly formed through the two sides of the spraying box, a liquid inlet is arranged at the top of the liquid storage tank, a mixing assembly is arranged in the liquid storage tank, a plurality of connecting pipes are rotatably connected through the inside of the spraying box, and a plurality of nozzles are fixedly connected to the connecting pipes. The spraying assembly is arranged, the spraying assembly can drive the connecting pipes and the nozzles to reciprocatingly swing in the spraying box, the reciprocating swing of the nozzles can ensure that the flame retardant is more uniformly distributed on the polyester filaments, the problems of local over-thickness or over-thinness are avoided, the consistency of the flame-retardant effect is improved, the contact area of the polyester filaments and the flame retardant is increased, more flame retardants can be covered on the polyester filaments, and the spraying effect is effectively improved.
