Description

A waste paper-plastic composite paper-plastic separation-plastic-skin granulation production system

technical field

The invention belongs to the technical field of waste carton treatment, in particular to a waste paper-plastic composite paper-plastic separation-plastic-skin granulation production system.

Background technique

With the rapid development of our country's economy, most of the packaging materials are made of various types of plastic films on cartons, which are printed and laminated. Paper-plastic composite materials are used. Applied to food packaging, the reuse of waste generated after being used has always been a big trouble that is difficult to deal with. Paper-coated and plastic-coated materials such as milk carton wrapping paper, coated paper, and PP bag labels must be removed during production or after use. Separated completely from plastic, otherwise it cannot be recycled.

The recycling and reuse of waste paper-plastic composite materials is an important way to regenerate resources, but due to the different properties of paper and plastic, this material cannot be directly processed and recycled: the first reason is that paper bags can be degraded, but plastics cannot be degraded; the second reason is that It is plastic that can be regenerated and granulated, but paper bags cannot be regenerated and granulated. If left untreated, both will cause environmental pollution and waste resources. To recycle, the paper and plastic must be separated first, and then processed separately. At present, the separation of paper and plastic in the market adopts the method of direct heating, and then manual tearing. There is a risk of burns in this method, and the separation is not complete, so that the performance of the product reproduced by using the recycled material in this method is greatly reduced, the labor intensity is high, and the efficiency is low. The previous wet processing method mainly relied on the impact force of water and the separation of humidity, the pulp could not be collected, and it occupied a large area; in order to separate the plastic skin and wood pulp fibers, most of the traditional pulpers used long-term and fully soaked pulp. method, but it is easy to cause waste and pollution of water resources, and the efficiency is not high.

At present, there are also paper-plastic separation systems imported from developed countries. As we all know, developed countries have a high degree of refinement in waste classification, and this paper-plastic separation system in developed countries selects different separation systems for processing according to different subdivided wastes. Domestic waste classification is still relatively extensive, most cities only use binary classification, and waste paper-plastic composite materials that can be recycled are often mixed with other materials, resulting in the import of paper-plastic separation systems in developed countries. The treatment of paper-plastic composite materials is not acclimatized: one is that the production efficiency is low due to the small feeding port; the other is that there are many other impurities in the waste paper-plastic composite materials, which often cause it to stop; many garbage disposal factories spend high A large number of imported paper-plastic separation systems purchased by foreign exchange are idle.

The plastic skin fragments after the separation of waste carton paper and plastic need to be recycled, but if they are not handled properly, it is easy to cause secondary pollution to the environment and waste of raw materials. The existing recycling method usually adopts the method of water separation and sorting, and the water consumption is particularly large. This process method has disadvantages such as high cost and large environmental pollution. After the separation of paper and plastic, during the extrusion molding process of waste plastics, due to the need for heating and the complexity of the components of waste plastics, a large amount of toxic fumes will be produced. The fumes contain toxic gases such as hydrogen chloride, methane, toluene, xylene and various heavy metals. compound. If these toxic gases are not treated effectively, they will cause secondary pollution to the atmosphere.

This utility model is suitable for the processing of directly collected waste plastics. When it is applied to the plastic processing after the separation of paper and plastic from waste cartons, due to its complex composition, only the physical treatment method of this utility model cannot be used for subsequent granulation processing. .
