Description

Method for recycling recyclable scrapped materials}

The present invention relates to a manufacturing method for the recycling of waste resources, and more particularly, to provide a manufacturing method for recycling waste resources such as waste cellulose, waste vinyl, and waste plastics, thereby preventing environmental pollution by treating the waste resources. Preventing, simplifying the process, reducing energy consumption, and reducing unnecessary equipment, along with low energy consumption, low-cost recycling technology, and simple facility structure, recycle renewable resources very effectively, thereby producing various recycled products. It relates to a manufacturing method for the recycling of waste resources to be used in.

In recent years, in order to recycle the environment and resources, devices for recycling agricultural or industrial waste vinyl by heating again have been developed.

Looking briefly at the configuration of such a device, on one side, a cylinder in which a hopper for injecting waste vinyl is installed, and a screw for transporting waste vinyl in the interior of the cylinder. I have the same problem.

The waste vinyl is put into the hopper as it contains a large amount of water due to the nature that needs to be washed for recycling, and there is no separate drain hole in the cylinder, so a large amount of water remains in the cylinder. The larger the amount of water remaining in the cylinder, the more bubbles are generated in the cylinder, thereby lowering the thermal efficiency when heating the waste vinyl, and causing a problem such as the possibility of explosion due to sudden expansion of water vapor.

On the other hand, in particular, due to the rapid development of the petrochemical industry, hazardous industrial wastes such as waste plastics, waste vinyls, waste PVC, and waste cellulose (waste paper) are rapidly increasing, threatening the survival of humanity.

Whether or not such harmful hazardous wastes can be properly disposed of environmentally is becoming a challenge for all humanity. In the case of wastes such as waste PVC, waste plastics, waste vinyl and waste cellulose, environmental pollution and harmful effects on the human body, and in the reality that petroleum resources are depleted and prices are rising as of now, it has value as a valuable resource, but Due to its difficulty in handling itself, it has emerged as a key issue in solving the waste problem.

In particular, the use of plastics and vinyls is increasing in the amount of plastics and vinyls (PE) in plastic bottles, garbage bags, and various product packaging areas for daily use, and the amount of waste vinyls in the process of operating the multi-covering and plastic house for agriculture is rapidly increasing. In addition, the amount of use is increasing in various containers and packaging for business use. Simple trashing and illegal disposal of waste plastic, waste vinyl, and waste PVC waste acts as an environmental pollution source that increases air pollution, soil pollution, and overall environmental load.

In particular, as air pollution, it acts as a source of dioxin, harmful gas and odor due to the incineration of waste PVC waste plastics and waste plastics. In particular, it has low performance to not incinerate or dispose of certain wastes, plastic wastes. Increasing the amount of dioxin hidden in the atmospheric environment, such as illegal incineration in incinerators, is also becoming a serious source of soil contamination by reducing soil porosity and preventing microbial traffic by being buried in the soil. In particular, in rural areas, there is a large amount of garbage left in the soil, and the source of healthy food production is fundamentally contaminated, which poses a fundamental problem that threatens human life. In addition, the volume is large, but the weight is small, which consumes a lot of money for collection and transportation, and collection from private collectors is avoided. Therefore, it is impossible to utilize resources as resources. In particular, the value as a resource is gradually losing due to the decrease in added value in resource regeneration. The use of vinyl is increasing due to the implementation of the volume-based waste disposal system, and the pollution of the landfill site is further increased by simply placing the waste in plastic bags. In addition, as a policy of segregation of wastes, renewable wastes are collected separately, but there is a tendency to become simple wastes due to collection avoidance and inefficiency of treatment.

Therefore, there is a problem in that plastic wastes that are difficult to be separated and collected are left unattended. Waste resources such as waste plastics and waste vinyl waste PVC are being discharged in huge quantities as described above, but most of them are trashed and are simply left to landfill or illegal incineration. Actually, since the amount of recycled waste resources such as waste plastic and waste vinyl is very small compared to the amount of discharge, it is a situation that pollutes the soil and the atmosphere because huge amounts of hazardous waste cannot be resourced and illegally disposed of.

The present invention is to solve the problems as described above, by providing a manufacturing method for recycling waste resources such as waste cellulose, waste vinyl, waste plastics, and the like, to prevent environmental pollution by the treatment of the waste resources, and simplify the process In addition, with the effect of reducing energy consumption and reducing unnecessary equipment, low energy consumption, inexpensive renewable technology, and simple facility structure regenerate renewable resources very effectively, resulting in recycled raw materials used to produce various recycled products. It is an object to provide a manufacturing method for the regeneration of.

The present invention provides a method for recycling waste resources such as waste cellulose, waste vinyl, and waste mixed plastics, thereby preventing environmental pollution caused by treatment of the waste resources, simplifying processes, reducing energy consumption, and reducing unnecessary equipment. In addition to the effect, low energy consumption, low-cost renewable technology, and simple facility structure make it possible to recycle renewable resources very effectively, thereby making recycled raw materials a very useful invention to be used in the production of various recycled products.

The present invention for achieving the above object and effect will be described in more detail through preferred embodiments as follows.

The manufacturing method for the recycling of waste resources proposed in the present invention comprises sorting, crushing and rolling waste materials such as waste cellulose, waste vinyl, waste mixed plastic, and waste materials such as waste wood, waste fibers, and waste leather; In addition, it is an object to realize a recycled product having strong elasticity and tension by mixing and compressing the waste mixture and the waste.

The manufacturing method for the recycling of waste resources according to the present invention comprises: separating and pulverizing waste cellulose, waste vinyl, and waste mixed plastic, respectively; Discharging the waste mixture by mixing the pulverized waste cellulose, waste vinyl, and waste plastic mixture at a constant ratio; After grinding the discharged waste mixture, it is melted, followed by compression molding with a press.

In addition, the waste material is crushed into a chip of a predetermined size by crushing it with a crusher, and then it is configured to be mixed with pulverized waste cellulose, waste vinyl, and waste mixed plastic at a predetermined ratio.

After the waste cellulose, waste vinyl, and waste plastics are sorted, they are crushed by a crusher and then transferred to a conveying device to be pulverized with a grinder.

In addition, it is preferable to add a process of crushing the waste material into chips of about 5 to 10 cm with a crushing machine, and then transferring the chips of the crushed waste material to a rolling machine to roll with an embossing roller. This is to ensure that the mixture and waste materials are mixed smoothly.

The mixture of the waste cellulose, waste vinyl, and waste plastic mixture and waste materials are mixed at a certain ratio, then crushed through a grinding or agitator for a homogenization process, and additives are added to improve the homogenization process as necessary. You can also use

The agitated or grinded mixture is melted with a pressurized melt reader, compressed in a press, and molded into various products.

Hereinafter, a detailed process of the present invention will be described.

First, waste mixtures of waste cellulose, waste vinyl, and waste plastics are sorted, put into a crusher, and finely crushed, and then pulverized into fine particles that are put in a crushing mixer. At this time, it is possible to remove the soil and the foreign substances in the waste mixture by separate washing process, but it is expensive and secondary waste water pollution occurs, and it is difficult to process large-capacity. The generated soil and foreign matter can be mixed with waste materials without being discharged.

Next, waste materials of waste wood, waste fiber, and waste leather are put in a crusher, and then crushed to a size of about 5 to 10 cm. At this time, if the water content of the waste material is too low, many fine chips are formed upon crushing, and if the water content is too high, energy is consumed in the drying process after manufacturing the chip, so that the water content of the material is adjusted to be 35-50%.

Next, the chip of the crushed waste material is rolled with an embossed roller to spread it thinly to increase the surface area so that the chips are adhered to each other in many areas when they are compressed, and also, the melted waste mixture resin penetrates well into the chip, creating strong adhesion and elasticity After increasing the over-bending strength, the rolled chips are then dried in a heat drying furnace at a temperature of 200° C. to lower the water content to about 3 to 6% to prevent air bubbles from forming during press compression.

Next, the pulverized waste mixture and the chips of the waste material are put into a stirrer at a desired mixing ratio according to the characteristics of the product, such as 2:8 to 5:5, and stirred so that they can be homogenized. Hide and implement so that the whole has a uniform color.

Next, a process of melting the agitated mixture with a pressurized melting reader is melted through a sequential pressurization process that gives a change in pressurization temperature, and the melted mixture is prepared by compression molding with a press.

The recycled raw materials manufactured as described above are provided in various forms through compression molding or injection molding, and thus, pallets, bulk bins, various files, substitute materials, road central separators, outdoor benches, sidewalk blocks, roof tiles, bricks, interior and exterior materials, etc. It can be used for a variety of purposes.
