The contents of the prior art include the problems of following the technology of developed countries, and the thermal expansion of air and thermal expansion of water when the US or Japan technology, which has excellent technology of sorting, crushing and drying process, is used in the material mixture of Korean renewable fuel. It is difficult to have a finished product having a shape due to the burst phenomenon, and when the solid recycled fuel (RDF) is extruded from the mixer, it has to be cut to a certain size and commercialized, and the recycled fuel has no value as a commodity. Defective products are also used as renewable fuel, but blown blanched products are difficult to remove the exothermic temperature, there is also a difficulty in work has a problem of low utility value.

The contents of the present invention will be described in detail with reference to the drawings in a manner applied to a single-phase screw type mixer.

1] is a perspective view of a mixer of the prior art, the inside of the mixer is heated by the heating device 20, there is a shaft of the screw 30, the shaft has a feed blade when the material is introduced into the rotational movement of the feed blade and As the tapered friction coefficient inside the mixer case 10 acts, the input materials are mixed and moved by the transfer distance of the transfer blade. In addition, since the mixer case part 10 and the screw 30 have a tapered shape, they are compressed and mixed while being heated and conveyed.

2] is an explanatory diagram of the bursting phenomenon caused by steam pressure, etc., which can find the cause of the prior art bursting phenomenon. The mixed material gathered in the output side forming frame 70 is sealed while the dissolved vinyl, plastic, and carbonized paper are mixed, and there is no input of material on the inlet side at a certain distance (time). As the material is introduced from the inlet side of (10), the material is constantly dissolved to block the inlet side, and the supporting force of the screw 30 transfer blade is added, so that the air or the steam gas 50 is thermally expanded therein. The only place where the thermally-expanded air or steam 50 acts as a pressure is the regenerated fuel forming mold 70 at the output side, so there is a pressure difference between the air pressure or steam pressure inside the mixer case 10 and the atmospheric pressure outside. A burst phenomenon occurs.

3 is an exemplary coupling of the secondary screw to the primary screw, the through-hole (60- compressed air or water vapor and gas to the outside of the center of the output side of the existing primary screw 30, which mixes, pressurizes and conveys the action. The groove 33 is formed so that the secondary screw 31 for forming a hole is coupled, and the secondary screw 31 is coupled to the groove 33 by a screw method, a welding method, and a primary screw. If attached using a method according to the manufacturing process during production, it is possible to prevent the burst phenomenon can produce a standardized recycled fuel (41). That is, since the recycled fuel extruded by the primary screw 30 is calculated while the secondary screw 31 is contained in the mold 70, the through hole 60 is rotated by the rotation of the secondary screw 31 inside the recycled fuel. Is formed, the steam or gas 50 is discharged out along the transfer blade of the secondary screw (31).

4] is an example of a square molding frame of the mixer case, the recycled fuel 40 produced by the output pipe forming mold of the circular pipe tube form of the prior art is easy to package in a firewood, but cut into a standard size to cut Difficult, there is a disadvantage in that the transfer storage operation is difficult in the present design constitutes the forming mold of the output unit of the square, hexagonal pipe tube form of the forming unit 70 of the output unit. According to the manufacturing method of the mixer case portion 10 to form a mold forming side 70. In the case of the circular molding die, while the recycled fuel 50 is being rotated, when the square or hexagon molding die 70 is used, the pressure-feeding rotational force by the primary screw 30 is square or hexagonal mold 70. It has the advantage that the density of the product is high because it acts as a part of the resistance by the pushing force, not the rotational force.

5 is an exemplary view of a solid recycled fuel, in the form of a square or hexagonal column in which a through hole 60 is formed by a forming mold 70. As the compression density is high and the characteristics of various work efficiency are not only excellent, the internal holes 60 are formed by the secondary screws 31, so that the ignition surface during combustion can be increased by the surface area of the internal holes, thereby increasing the exothermic temperature. By stably increasing the exothermic temperature, the action of burning air pollutants at high temperatures and the application of renewable energy 41 may be broadened.

FIG. 6 is an explanatory view of the pedestal of the regenerated fuel and the cooling system calculated by the forming die. When the regenerated fuel 41 is pushed out of the forming die 70, a plurality of rotating rollers 91 are placed on the horizontal support of the pedestal 90. The rotary roller 91 of the pedestal 90 having the combined configuration supports the weight of the regenerated fuel 41, and the rotary roller 91 rotates and moves by the force of the primary screw 30 acting as the discharge pressure. This prevents the recycled fuel 41 from breaking. If there is no pedestal 90, the product is broken by weight, so the standardization rate of the product is small, and if the standardization is small, the control range of the heating temperature is also narrowed.

In addition, when the regenerated fuel 41 is calculated by the forming mold 70 to the pedestal 90, the cooling time may be extended to the inside of the regenerated fuel by the present natural cooling, and thus there may be an operational risk. Thus, in the present invention, a cooling system that blows cool air (an apparatus for blowing air cooled by an 80-refrigerant through an operation of a blower or an operation of an air compressor) is installed on an upper portion of the pedestal 90 to cool the regenerated fuel 41. Let's do it. The cooled fuel thus cooled is safely cut to a certain size by the cutting operation of the cutter.

When the inside of the mixer is thermally expanded, the through-hole 60 formed by the secondary screw 31 of the present invention prevents the phenomenon of phenomena and increases the ratio of products that can be standardized, and the inner through-hole 60 increases the combustion efficiency during combustion. It improves the problem caused by incomplete combustion and increases the heat generation control range.

The secondary screw 31 is installed in the screw part 30 of the mixer to improve the quality by preventing bursting, improving combustion efficiency, high heat generation temperature, burning of pollutants by high temperature, etc., and forming the mixer mold in a cylindrical structure. In the case of forming a mold 70 having a hexagonal structure, the product can be standardized by increasing the density, facilitating transportation and loading, and by using a roller 91 pedestal 90 configured with a cooling system 80. Can be.
