A filter device for polyester fiber processing

Abstract

The invention discloses a polyester fiber processing technology related to the polyester fiber processing field; the filtering device adopted in the process comprises an upper conduit, a lower conduit and a filter screen, and the upper conduit and the lower conduit are fixedly arranged on a screen changing box, and The filter screen is arranged in the screen changer box; the screen changer box at the communication position of the upper conduit and the lower conduit is provided with a circular arc sealing surface, a rotating shaft is arranged in the screen changer box, and four brackets are evenly fixed and distributed on the rotating shaft at equal angles. , The outer support plate and the inner support plate of the bracket are fixedly connected by the frame rod, the rotary contour surface of the outer support plate matches the outer contour of the circular arc sealing surface, and the position of the circular arc sealing surface and the rotating shaft on the same horizontal line is provided with a support block; One end of the rotating shaft passes through the screen changing box and is fixedly connected with the power piece, and the other end of the rotating shaft corresponding to the screen changing box wall plate is fixedly provided with a net feeding device; the present invention solves the problem that the traditional device has a small number of filter screens and low efficiency. technical issues.

Description

technical field [0001] The invention relates to the field of polyester fiber processing, in particular to a filter device for polyester fiber processing. Background technique [0002] During the extrusion process of hot-melt polyester fiber, the polyester fiber melt is plasticized and heated for a long time, and there will be decomposition residues in the melt, plus impurities in the raw materials, once they enter the extruder head , it will cause blockage of the flow channel, defects in plastic products, and even normal production; in order to filter out impurities and make the pure melt enter the extrusion molding head smoothly, it is usually between the screw head and the extrusion molding head. Set up a filter screen to prevent impurities and foreign matter from entering the molding head; as the extrusion time continues, the debris on the filter screen gradually accumulates, causing the head pressure to increase and the flow rate to decrease, and when a certain pressure ...

Problems solved by technology

[0006] The purpose of the present invention is to provide a filter device for polyester fiber processing, to solve the above-mentioned problems in the background technology, there are some screen changers that do not need to be shut down to change the screen on the market, but in the process of changing the screen, they are limited In fact, the number of nets that can be changed is very small, and the waste nets after the net change cannot be properly placed, which may pollute the hot-melt polyester fiber again.
