Abstract

The invention discloses a waste film recycling and cleaning process. The waste film recycling and cleaning process comprises the following specific steps of firstly, conveying waste films into a breaking machine for breaking treatment through a conveying system, so that a waste film fine material is obtained; then, conveying the waste film fine material into a double-screw cleaning machine for cleaning treatment, so that impurities in the waste film fine material are removed; subsequently, feeding the cleaned waste film fine material into a centrifugal dewatering machine for dewatering treatment through a feeding device, so that moisture in the waste film fine material is removed; and finally, introducing the waste film fine material obtained through dewatering treatment into a drying box body for drying treatment, and outputting a finished product through a material bin. In this way, by means of the waste film recycling and cleaning process, the waste films can be recycled and cleaned efficiently and rapidly; and in addition, the recycled product is high in purity and good in quality.

Description

A kind of useless film recovery and rinsing technique

Technical field

The present invention relates to a kind of size reduction machinery, particularly to a kind of useless film recovery and rinsing technique.

Background technology

In recent years, thermal contraction packaging film was developed rapidly, just expanded PET, PE, PP/ to from single PVC shrink film The multi items film such as PVDC, being continually changing of the market demand, positive multi-level, the feature direction of heat-shrinkable film is developed, and occurs Many new technologies and new product, but current all kinds of films usually recycle to it after a procedure, but existing rank Section is relatively low to the useless film rate of recovery, and is usually mingled with more impurity in the useless film reclaiming, after product remanufacturing is reclaimed in impact End product quality.

Content of the invention

The invention mainly solves the technical problem of provide a kind of useless film recovery and rinsing technique, can efficiently, rapidly to useless film Reclaimed and cleaned, and the product purity height being reclaimed, quality are good.

For solving above-mentioned technical problem, one aspect of the present invention is:A kind of useless film recovery and rinsing work is provided Skill, specifically includes following steps:

(1), by induction system, useless film is delivered in breakage device and carries out break process, obtain useless film fines;

(2), above-mentioned useless film fines transmitted be carried out processing to twin-screw cleaning machine, remove the impurity in useless film fines, In described twin-screw cleaning machine, water temperature controls at 25-35 DEG C, and scavenging period is 10-20min;

(3), the useless film fines after above-mentioned cleaning be fed in dewaterer by feeding device carry out processed, described dehydration By the way of centrifugal dehydration, rotating speed is 150-250r/min to machine, for removing the moisture in useless film fines;

(4), the useless film fines after above-mentioned processed be passed through drying box be dried process, export to eventually through feed bin Product.

In a preferred embodiment of the present invention, described feeding device is bolt feeder.

In a preferred embodiment of the present invention, described induction system is band magnetic frame.

In a preferred embodiment of the present invention, the drying temperature in described drying box is 40-60 DEG C.

The invention has the beneficial effects as follows:The present invention can efficiently, rapidly to useless film be reclaimed and be cleaned, and returned The product purity received is high, quality is good.
