Description

RDF molding machine using waste resources {omitted}

The present invention is a solid fuel alternative fuel shaping device, which collects waste materials with high calorific value (4000㎉ / kg or more), and sorts and removes metals and other non-combustibles. It is a waste recycling solidifying device for molding the mixed waste to be 6000 ~ 8000 ㎉ / kg).

Conventional industrial wastes and municipal wastes have been generally incinerated and landfilled. However, this method has many problems such as NIMBY phenomenon and landfill shortage due to incineration not only in terms of environmental protection but also economic and social aspects. Proper and effective alternatives are urgently needed.

When waste treatment is required to solve the above problems, eco-friendly treatment of waste and use of it as alternative energy leads to the accumulation of national economic resources and productivity improvement in the industrial society, thus creating economic and social added value. It is expected.

Conventional waste disposal methods cause problems such as air pollution due to incomplete combustion and lack of prevention facilities, and soil pollution due to landfill. The same waste treatment system will have to be completely reconfigured.

In order to solve the above problems, a small amount of lime is added to a polymer compound (synthetic resin, synthetic rubber, synthetic fiber, PP, PE, etc.) that increases air pollution during incineration while maintaining high calorific value among industrial wastes and household wastes. It is added to make it a solid fuel to neutralize the harmful gases generated during combustion, and aims to promote waste recycling.

To achieve this goal, waste is recycled through systems such as sorting, crushing, drying and molding.

This system includes raw material storage to selectively collect and classify combustibles among industrial wastes and household wastes, sorting unit for transporting these wastes to sort non-combustibles, and shredding unit for crushing selected wastes. , A cutting device unit for cutting shredded waste, a drying device unit for drying the cut waste, a quantitative supply unit for quantitative supply thereof, a solidification molding unit for forming a molding process by receiving a quantitative supply, waste gas combustion and hot air heater unit, Cooling unit for cooling device, shredding for crushing and cutting cooled solid, cutting device, drying device, control device for controlling rotation speed and molding heating chamber temperature It is comprised by the heater apparatus etc. which heat to a chamber.

Hereinafter, a detailed description of the present invention by the accompanying drawings.

1 is a process chart for solidifying waste fuel by using the present invention, Figure 2 is a detailed view of the characteristic forming apparatus of the present invention, the polymer compound belonging to the high calorific value of industrial waste, waste synthetic resin, synthetic rubber. Belt for removing metals and non-combustibles from wastes carried in mixed input device (9) that mixes high calorific value, heavy calorific value and low calorific waste by collecting and stacking high calorific waste such as waste fiber, waste wood, waste paper and synthetic fiber Waste shredded in the shredding device 2 for shredding the waste sorted by the conveyor sorting device 1 is again cut in the cutting device 3 to adjust the size and state so that large pieces do not occur.

The cut waste has a non-uniform moisture content, but it is supplied to the drying apparatus 4 and dried to be uniformly hot to solidify in a fixed-quantity supply device 5 which supplies a predetermined amount by stirring the mixed waste to be evenly mixed. The solids supplied to the molding apparatus 6 and solidified are transferred to the cooling apparatus 8 to cool down, then crushed and transferred to the cutting apparatus 10.

In the sorting device (1) to remove the non-combustibles such as metals, glass bottles, stones, ceramics, etc. mixed in the waste to prevent wear and breakage of the crusher, cutter, molding screw and improve the production capacity.

In the sorting method, it is possible to remove impurities such as soil by first sorting by manpower and secondly sorting metals by using magnet and thirdly by vibrating screen conveyor.

The waste is crushed and cut into 5 to 10 cm in size through the shredding device 2 and the cutting device 3, and the mixing of the raw materials for each component is for homogeneous calorific value of the product after molding.

Drying device 4 for drying the crushed and cut waste is a device for completely removing and drying the moisture contained in the waste and the mixing function, the heat supplied to the waste gas combustion and hot air generator (7) The alternative energy can be used as a solidified fuel, and even if gas is generated, the harmful gas can be sufficiently removed through the secondary combustion device of the waste gas combustion and the hot air generator. In addition, the drying apparatus is equipped with a control device for adjusting the drying speed and temperature to fully exhibit the effect and function of drying.

The waste mixed and dried in the drying device 4 is supplied with a certain amount of raw material to the solidification molding device 6 through a fixed-quantity supply device 5 to uniformize the quality of the product and to automate the molding process. It is a device that lets you.

The molding apparatus 6 for solidifying the waste is formed of a molding double screw 21, as shown in detail in FIG. 2, and a heating coil plate 20 which encloses and heats an external screw case and accumulates heat of the molding machine. The pyrolysis gas generated in the heating chamber 22 and the molding process is sucked into the waste gas combustion and the hot air generator 7 through the pyrolysis gas suction duct 23 to be completely burned, and the calorific value of the hot air generator is further increased.

In addition, the molding double screw 21 is installed in the molding heating chamber 22 together with the heating coil plate 20, and the heating coil plate 20 heats the case of the molding double screw 21, and the heating device 12. ) Can generate high efficiency with little energy by heating to the molding heating chamber 22 from the outside. Molding heating chamber (22) temperature is maintained at 150 ~ 200 ° to be solidified in the state that is not melted, it is characterized by forming a void in the product to allow heat to penetrate into the void when used as desing energy. .

Since the molded product extruded from the solidification molding apparatus 6 is hot and is discharged softly when discharged, the molded product 6 is temporarily stored in a storage tank while operating and cooling a fan in the cooling apparatus 8 and then crushed and cut off from the first discharged (10). After the crushing and cutting process, the solidification fuel of alternative energy is discharged to where it is needed.

As described above, it is more effective to save resources and promote recycling by making it an alternative energy by burning it rather than burning it.
