Problems solved by technology

In order to overcome the above problems, it is necessary to solve the compatibility problem between garbage plastics and between garbage plastics and fillers first, so it is necessary to develop a new type of multifunctional composite modifier, which must have a compatibilizer and a coupling agent. In order to improve the compatibility between waste plastics and between waste plastics and fillers, a new production process can be designed

Embodiment 1

[0022] Embodiment 1, the garbage plastic sorting and rough processing process of the present invention includes plastics and impurities separation, plastic air-drying, granulation and other processes; the garbage plastic raw materials are first sent to the crushing equipment to be broken into flakes, and then the broken Garbage plastic flakes are fed into the winnowing equipment, and the plastic flakes and impurities in them are propulsed with the spiral of hot air flow, because vibration will be generated during the propulsion process, and due to the density difference between plastics and impurities, the plastics and impurities are completely separated And fall in different positions to select plastic flakes and remove impurities. At the same time, due to the accelerated vaporization of water under the action of hot air, the dry and clean plastic flakes selected by wind are sent to granulation equipment to make reusable particles. The crushing equipment, winnowing equipment ...

Embodiment 2

[0023] Embodiment 2, the control system of the present invention is connected with feeding conveying device, crushing device, winnowing equipment, impurity removing device and granulation equipment respectively; Utilize the principle of belt conveyor to sort out the waste dump under the control of computer Garbage plastics are sent to the crushing system. By measuring the content of moisture and impurities, the computer controls the speed of the conveyor belt to ensure uniform feeding and drying of the flakes; the sawtooth-shaped rotating blade is used to tear the garbage plastics, The film is made into flakes, and the flakes are sent to the drying system by the blower. Because the density of the plastic flakes and impurities is different, the flakes with low density are sent out, and the impurities with higher density fall into the impurity removal system to achieve crushing and the first The second impurity removal process; the heat generated by the hot air stove is used to c...

Embodiment 3

[0024] Embodiment 3, the special equipment used in the washing-free recovery method of garbage plastics according to the present invention includes feeding conveying device, crushing device, winnowing equipment, impurity removing device, granulating equipment, control system, and the control system is connected with feeding conveying device respectively , crushing device, air separation equipment, impurity removal device and granulation equipment are connected; the feeding conveying device adopts a belt conveyor, the crushing device adopts a sawtooth rotating blade, the air separation equipment includes a hot blast stove, a blower, and the impurity removal device includes air separation equipment At the bottom of the chamber, the granulation equipment includes a screw feeding device, a vibrating device and a granulation device installed on the feeding port; the control system includes an industrial computer and an induction device; a heating device can also be installed at the o...

Abstract

The invention discloses a method for recycling garbage plastics and special equipment, belonging to a method for recycling garbage plastics and mainly solving the technical problems of high water consumption, high operating cost and higher pollution to the environment and the like in the traditional water separation process. The method is characterized by comprising procedures of separation for plastics and impurities, air drying for plastics, granulation, modification of plastics and re-granulation. The method specifically comprises the following steps of: firstly, conveying the raw materials of the garbage plastics into a crushing apparatus, and crushing into sheet-like materials; secondly, conveying the crushed garbage plastic sheets into a wind separator, spirally propelling plastic sheet materials and impurities therein along with the hot air flow, generating vibration during the propelling, completely separating the plastics from the impurities and falling on different positions due to density difference between the plastics and the impurities, picking out the plastic sheet materials and removing impurities; simultaneously, accelerating vaporization of moisture in the action of hot wind, sending the dried and clean plastic sheet materials subjected to the air separation to a granulation device and making into reusable particles; and finally, adding a modifier with compatible and coupling property to the garbage plastic particles, mixing and then making into plastic particle materials for producing products. According to the invention, the garbage plastics can be recycled, and the method is relatively simple and the pollution to the environment is little. The treated recycled plastics comprise garbage plastics capable of being used for manufacturing of cast-in-place reinforced concrete core moulds and raw production materials such as granulation materials and the like, or manufacturing industry, building and articles for daily life and the like.

Description

technical field [0001] The invention relates to a process for recycling waste plastics, in particular to a process for recycling, processing and reusing waste plastics. Background technique [0002] It is relatively easy to recycle and dispose of relatively large waste plastics that have a good overall recovery from the society, and the utilization rate is also the highest; There are many impurities, the treatment process is complicated, and the cost is high. Therefore, the scattered plastic daily necessities contained in domestic waste are basically not recycled. They are generally disposed of by landfill or incineration, which not only causes waste of resources, but also easily pollute the environment. Even if the scattered plastic daily necessities contained in domestic garbage are sorted out for reuse, the existing recycling method usually adopts the method of water separation and sorting, which consumes a lot of water. This process has high cost and great environmental...
