Abstract
The invention discloses a kind of plastic bottle recovery methods, comprising the following steps: pretreatment, according to color by plastic bottle carry out classification and by bottle cap and plastic bottle status from；It crushes, sorted plastics body is crushed；The plastics body crushed is carried out boiling by boiling；It is dry, the plastic bottle after boiling is dried respectively；Separation is separated the plastics body of crushing with the impurity such as sandstone therein, soil, iron filings are mixed in using cyclone separator；Melting, is placed on melting extrusion in melt extruder for the crushing plastics body separated.The present invention has the advantage that recycling quality is high, recovery efficiency is high.
Description
Technical field
The invention belongs to plastics recovery fields, and in particular to a kind of plastic bottle recovery method.
Background technique
Plastic bottle is a kind of common packaging, had both met the recycling of waste plastic bottle the requirement of environmental protection, and had also complied with
Economic interests during recycled plastic bottle, in order to improve the purity of plastic bottle, will not only be removed in recycled plastic bottle
Label, glue and beverage residue, also separate bottle cap.In traditional mineral water bottle recovery technology, since processing is set
Standby simple and crude and processing method is coarse, and not only production efficiency is low, but also plastics recovery is of low quality.
Summary of the invention
It is an object of the invention to: a kind of plastic bottle recovery method is provided, solves that existing plastic bottle recycling quality is low, recycling
The problem of low efficiency.
The technical solution adopted by the invention is as follows:
A kind of plastic bottle recovery method, comprising the following steps:
A. pre-process, according to color by plastic bottle carry out classification and by bottle cap and plastic bottle status from；
B. it crushes, sorted plastics body is crushed；
The plastics body crushed is carried out boiling by c. boiling；
D. it dries, the plastic bottle after boiling is dried respectively；
E. separate, using cyclone separator by the plastics body of crushing with to be mixed in sandstone therein, soil, iron filings etc. miscellaneous
Matter separates；
F. it melts, the crushing plastics body separated is placed on melting extrusion in melt extruder.
Preferably, in the step c, the boiling temperature is 80 to 100 DEG C.
Preferably, it in the step c, is stirred during the cooking process.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
After the present invention is by the crushing of particle body, boiling, drying, some impurity in plastic bottle can be tentatively removed,
The large granular impurities such as plastic bottle and iron filings, sandstone are removed by cyclone separator again, the plastic bottle purity that entire method obtains
It is high, high-efficient.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention, i.e., described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Therefore, based on the embodiment of the present invention, those skilled in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It should be noted that the relational terms of term " first " and " second " or the like be used merely to an entity or
Operation is distinguished with another entity or operation, and without necessarily requiring or implying between these entities or operation, there are any
This actual relationship or sequence.Moreover, the terms "include", "comprise" or its any other variant be intended to it is non-exclusive
Property include so that include a series of elements process, method, article or equipment not only include those elements, but also
Further include other elements that are not explicitly listed, or further include for this process, method, article or equipment it is intrinsic
Element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that including described
There is also other identical elements in the process, method, article or equipment of element.
For the existing plastic bottle recycling problem that quality is low, recovery efficiency is low.The present invention provides a kind of plastic bottle recycling side
Method, comprising the following steps:
A. pre-process, according to color by plastic bottle carry out classification and by bottle cap and plastic bottle status from；
B. it crushes, sorted plastics body is crushed；
The plastics body crushed is carried out boiling by c. boiling；
D. it dries, the plastic bottle after boiling is dried respectively；
E. separate, using cyclone separator by the plastics body of crushing with to be mixed in sandstone therein, soil, iron filings etc. miscellaneous
Matter separates；
F. it melts, the crushing plastics body separated is placed on melting extrusion in melt extruder.
Plastics body is separated with bottle cap first, boiling is carried out after plastics body is then ground into fragment, in the mistake of boiling
The viscosity of the label on plastics bottle fragment and Liquid Residue viscosity are removed in journey, then plastics bottle fragment is dried, it will
Plastics bottle fragment after drying carries out cyclonic separation, using specific gravity difference, the impurity such as sandstone, soil, iron filings and plastic bottle are broken
Piece separates, and obtains the higher plastics bottle fragment of purity, and plastic flakes after purification are then carried out melting extrusion.The present invention is logical
It crosses after the crushing of particle body, boiling, drying, can tentatively remove some impurity in plastic bottle, then pass through cyclone separator
The large granular impurities such as plastic bottle and iron filings, sandstone are removed, the plastic bottle that entire method obtains is with high purity, high-efficient.
Feature and performance of the invention are described in further detail with reference to embodiments.
Embodiment 1
A kind of plastic bottle recovery method that present pre-ferred embodiments provide, in the step c, the boiling temperature is
80 to 100 DEG C.
The working principle of the present embodiment: temperature setting has certain bactericidal effect at 80 to 100 DEG C, is on the other hand conducive to
The viscosity of label on plastics bottle fragment and Liquid Residue viscosity are removed.
Embodiment 2
Present pre-ferred embodiments provide a kind of plastic bottle recovery method, in the step c, during the cooking process into
Row stirring.
The working principle of the present embodiment: stirring is conducive to the viscosity of the label on plastics bottle fragment and Liquid Residue viscosity
Removal.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
