Description

Efficient mixing extruder system for spinning waste polyester cloth

Technical Field

The utility model relates to a high-efficiency mixing extruder system for spinning waste polyester cloth.

Background

The existing spinning technology of the waste terylene cloth is a two-step method, wherein color master batches are needed to be prepared firstly, then the color master batches and raw materials are mixed by a mixer, and then the mixture is melted by a common single screw to be spun (the single screw has no mixing function). In the method, the melt viscosity is reduced, the viscosity of 0.70cp meeting the requirement is difficult to achieve, sometimes the viscosity is reduced to only 0.65cp, and the melt quality is not good; and this approach is also inefficient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide an efficient mixing extruder system for spinning waste polyester cloth, which does not reduce viscosity compared with the conventional spinning mode, changes the mode of the conventional extruder, adopts a mode of matching a reciprocating mixing extruder with a spinning box, and has the advantages of high efficiency, large high-speed spinning supply and good melt quality.

In order to achieve the aim, the utility model adopts the technical scheme that the efficient mixing extruder system for spinning the waste polyester cloth comprises a raw material bin and a pigment bin, wherein discharge holes of the raw material bin and the pigment bin are connected with a feed inlet of a reciprocating mixing extruder;

a discharge port of the reciprocating mixing extruder is connected with a spinning box; or the discharge port of the reciprocating mixing extruder is connected with the spinning box after passing through the first melt filter, the buffer tank, the axe bottom melt pump and the second melt filter in sequence. The method changes the prior method of firstly matching colors and then adopting an extruder and then spinning the mixture in a spinning box, but directly adopts a compound mixing extruder, and the raw materials and the pigment are added at the same time, so that the melt viscosity reaches the requirement of 0.70cp, and the method has the advantages of high working efficiency, large high-speed spinning supply and good melt quality. The prior pigment is subjected to two times of melting processing, so that the pigment is damaged, only one time of processing is needed at present, the pigment is directly added by a one-step method, and the mixing and melting are finished by a reciprocating single screw, so that the pigment is uniformly distributed and dispersed. That is, less pigment can be added to achieve the same vividness. The pigment cost is saved. And handling costs.

The further technical scheme is that the raw material bin and the pigment bin are arranged side by side, and the raw material bin and the pigment bin are both provided with a metering scale. The metering scale is arranged to ensure that the amount of raw materials and pigment entering the compounding extruder is satisfactory.

The further technical proposal is that the pigment bin comprises a carbon black bin; and a granulating machine and an air-cooled vibrating screen are sequentially arranged in front of a feeding port of the raw material bin according to the feeding direction, wherein the granulating machine is used for feeding shredded waste polyester cloth, and the air-cooled vibrating screen is used for screening large lump materials. The granule machine can crush and granulate torn waste terylene cloth, and the air-cooled vibrating screen can absorb and cool raw materials entering the reciprocating mixing extruder, so as to ensure the accuracy of the raw material proportion of the reciprocating mixing extruder. The air-cooled vibrating screen is used for screening large blocks, and the large blocks need to pass through the pulverizer and then enter the raw material bin.

The further technical scheme is that a vacuumizing port for exhausting air in the buffer tank and a laser sensor for detecting the liquid level of the melt are arranged on the top of the buffer tank. After the laser sensor detects the melt level, the yield of the main machine and the metering scale can be adjusted.

The further technical scheme is that the laser sensor is electrically connected with the metering scale and is electrically connected with the aggregate machine.

The utility model has the advantages and beneficial effects that: compared with the prior spinning mode, the viscosity is not reduced, the mode of the prior extruder is changed, and the mode of using a reciprocating mixing extruder to match a spinning box is changed, so that the efficiency is high, the high-speed spinning supply is large, and the melt quality is good. The method changes the prior method of firstly matching colors and then adopting an extruder and then spinning the mixture in a spinning box, but directly adopts a compound mixing extruder, and the raw materials and the pigment are added at the same time, so that the melt viscosity reaches the requirement of 0.70cp, and the method has the advantages of high working efficiency, large high-speed spinning supply and good melt quality. The metering scale is arranged to ensure that the amount of raw materials and pigment entering the compounding extruder is satisfactory. The granule machine can crush and granulate torn waste terylene cloth, and the air-cooled vibrating screen can absorb and cool raw materials entering the reciprocating mixing extruder, so as to ensure the accuracy of the raw material proportion of the reciprocating mixing extruder. After the laser sensor detects the melt level, the yield of the main machine and the metering scale can be adjusted. The prior pigments are subjected to two melt processes, which are detrimental to the pigments, and now only one process is required, i.e. less pigment can be added to achieve the same vividness. The pigment cost is saved. And handling costs.
