Description
Technical field
The utility model belongs to the feed separation technology, particularly relates to a kind of horizontal continuous separation process system of aluminium plastic composite packaging material that can carry out to aluminium plastic composite packaging material the shaftless spiral of employing of the continuous separating treatment of industrialization.
Background technology
The paper plastic-aluminum composite packing material is a kind of common packaging material, is widely used in the packings such as milk and soft drink.Raising and lack of raw materials along with people's environmental consciousness, it is very necessary that the regeneration of paper plastic combined package becomes, when paper plastic combined package is carried out regeneration, normally with after the paper substrate separation wherein, the more remaining material that is formed by aluminium foil and plastics is separated again.
Wherein, the regenerative use technology of paper plastic-aluminum composite packing waste mainly comprises two classes, and a class is the Direct Regeneration technology, is about to the paper plastic-aluminum composite packing Integral-crushing and processes the rear new raw material of regeneration; Another kind of is the separation regeneration technology, is about to recycle respectively after three kinds of materials separation in the paper plastic-aluminum composite packing.Relative separation regeneration techniques, Direct Regeneration technology are mainly moulded wood and color happy plate as main to produce extrusion molding, and it can't reclaim paper pulp, plastics and aluminium effectively, does not embody the self-value of paper fiber, aluminium foil and plastics.
The separation regeneration technology can be divided into two parts according to its separation process, at first is paper and the separating of plastic-aluminum, i.e. the paper pulp isolation technics; Next is separating of aluminium foil and plastics, i.e. aluminum-plastic separation technology.Paper separates with plastic-aluminum, and the method by hydraulic pulping can realize that the present comparative maturity of this technology is used more extensive.Removed key and the difficult point that is the separation regeneration technology of separating of the aluminium foil of the aluminium plastic composite packaging material behind the paper pulp and plastics.
At present, when the aluminium plastic composite packaging material that aluminium foil and plastics are compounded to form separates, usually adopt the wet separation technology, being about to aluminium plastic composite packaging material is soaked in the release agent, thereby the cohesive force that destroys between each layer by dissolving or swelling action makes aluminium, moulds separately, realize the Chemical Decomposition of plastic-aluminum, this process also can be described as the Chemical Decomposition reaction of plastic-aluminum; And then dry, physical separation that separation etc. realizes plastic-aluminum.For this reason, prior art has proposed a kind of realization aluminium plastic composite packaging material continuous separating system, comprise and soak separator, centrigugal swing dryer and cylinder centrifugal dressing machine, wherein, be provided with the axle spiral in the immersion separator and transmitted material, its separation process may further comprise the steps: (1) is dropped into aluminium plastic composite packaging material and is loaded with in this immersion separator of release agent, and process is carried out Chemical Decomposition, and by there being the axle spiral to transfer to centrigugal swing dryer; (2) centrigugal swing dryer can dry processing with the chemically separated material of the process of sending into, and removes release agent wherein, and the material after drying is sent to centrifugal dressing machine; (3) centrifugal dressing machine utilizes under the center rotor effect of high speed rotating, aluminium foil is separated with plastics, and be expelled to respectively plastic granulator and eddy current sorter, and the eddy current sorter can be connected with the aluminium smelting apparatus and obtains aluminium.
