Embodiment

[0057] When in use, the first step is to clean up the recycled variegated polyester waste cloth to remove debris and dust for later use;

[0058] In the second step, put the cleaned variegated polyester waste cloth into the agglomerator 21, start the granulator 21 to work, and crush the variegated polyester waste cloth into tiny flakes. With the high-speed rotation of the granulator 21 blades, the When the temperature of the polyester material rises to 180°C or 200°C or 220°C (preferably 200°C), the softened polyester material is shrunk by spraying liquid nitrogen through the cooling liquid nitrogen supply device 20 to become pellets, which are crushed in the variegated polyester waste cloth During the process, the water vapor and dust generated by the polyester material are pumped out by a blower; this can reduce the degree of hydrolysis in the post-processing process;

[0059] The front end of the extrusion mixing system is an extrusion section 23 and is provided with a mixt...

Abstract

The invention discloses a spinning, vacuumizing and mixing extruder of dacron waste cloth. The spinning, vacuumizing and mixing extruder comprises an agglomeration machine, a reciprocating type mixing extruder and a single-screw-rod extruder in sequence along a line production direction, wherein the reciprocating type mixing extruder comprises an extruding and mixing system, a reciprocating driving system, an electric appliance control system and a temperature control system; the extruding and mixing system comprises a machine barrel which is arranged by sections, and a screw rod and a pin which are matched with each other and are arranged in the machine barrel; the machine barrel which is arranged by sections comprises an extruding section and a mixing section; the extruding section and/or the mixing section are/is provided with a vacuumizing hole; the vacuumizing hole is connected with vacuumizing equipment. By virtue of the equipment disclosed by the invention, the reciprocating type mixing extruder is innovatively used for mixing dacron materials before materials enter the single-screw-rod extruder, and steam and an oiling agent in the dacron materials, and auxiliary agents used in other spinning processes are pumped away, so that the degradation of the dacron is reduced, and the quality of regenerated dacron fiber yarns is improved.

Description

technical field [0001] The invention relates to a vacuum mixing extruder for spinning polyester waste cloth. Background technique [0002] As we all know, my country is a big country in the textile industry, and it is also a big country in textile consumption. Every year, my country's waste textiles are as high as tens of millions of tons. Polyester (PET) fabrics account for a considerable proportion of waste textiles. Therefore, how to recycle waste polyester fabrics through reasonable and effective methods has become an urgent problem to be solved. The existing polyester Almost all waste materials are buried and incinerated as garbage, causing damage to the environment, and the reuse rate is extremely low. In the existing polyester green treatment, the waste polyester fabric can be recycled and reprocessed to make it into recycled polyester fiber filaments. However, the existing polyester is often mixed and extruded directly through a single-screw extruder. Such mixing e...
