In general, many household garbage is generated during the life of our society, and general household garbage such as plastic garbage, paper, wood, and plastic garbage is generated.

There are many common household garbage generated in family life, such as paper and wood, which rot when buried in the ground. On the other hand, many garbage that does not decay when buried in the ground like vinyl and plastic. In large poultry houses or farm houses, , A lot of livestock manure excreted by chickens is emitted.

Among these, waste of paper and wood can be buried and incinerated in the ground. However, vinyl and plastic waste do not decay when buried in the ground, but when they are incinerated, many harmful gases are generated in large quantities. It is expensive.

In addition, when organic wastes including food waste and livestock manure are buried in the ground, they flow into ground water and smell bad when using ground water. As a result, not only water pollution but also surrounding environment are seriously polluted. Therefore, It can be said that it is preferable not to be buried in the ground.

However, organic wastes from food waste and livestock manure have accumulated for a long period of time, and when they are fermented naturally, various perennial germs propagate vigorously, and the compost produced by these uses causes the crops to become sick easily and weeds become vigorous due to the pernicious bacteria .

Therefore, when compost is made from organic waste of food waste or livestock manure, fermentation drying method that mixes with moisture regulator periodically in the fermentation tank of the fermentation drying room should be used to make a compost which has a large amount of aerobic microorganisms cultured. The cost is increased.

FIG. 2 is a block diagram showing a process of manufacturing an alternative fuel according to the present invention. Hereinafter, a process of manufacturing an alternative fuel using the manufacturing apparatus of the present invention will be described in detail.

The first step (preparation of raw material)

In the first step (S100), various general household garbage (food waste, vinyl garbage, paper, wood, plastic material garbage) generated in our society is collected, cut into pieces, cut into pieces, and prepared.

The size of the main raw material to be cut as described above is preferably within 1 to 3 cm. If it is too large, extrusion molding is difficult because it does not clump well. When the size of less than 1 cm is too hard, do.

Step 2 (mixing of the raw material and the sub ingredient)

In the second step (S200), the mixture is prepared by mixing the manure prepared in the cut to a predetermined size and manure produced in the livestock (hereinafter referred to as 'livestock manure') as a minor ingredient at a predetermined ratio.

The mixing ratio of the main raw material and the auxiliary raw material is preferably 70 to 80: 20 to 30% by weight, and the livestock manure is a mixture of the water used in the process of raising livestock, urine, Refers to a state in which water is mixed with the above-mentioned minute and yaw so that it is moist.

Therefore, the mixture of the main ingredient and the additive material is well-packed like a dough which is dewatered by moisture-containing livestock manure.

The third step (compression transfer step of the mixture)

The third step S300 is a step of putting the mixture, which has been rolled up, into the inlet 110 of the molding machine 100 and pushing the mixture to the nozzle forming part 150 by the conveying extrusion part 130.

Since the mixture is rolled up, it is strongly compressed while being conveyed through the conveying extrusion part 130.

Step 4 (heating step of the mixture)

The fourth step S400 is a step of heating the mixture to be compressed and conveyed to a high temperature of 150 to 200 DEG C just before passing through the nozzle forming part 150. [

If the heating temperature is lower than 150 ° C., the vinyl garbage and plastic garbage do not melt well. If the heating temperature is higher than 200 ° C., the plastic garbage and the plastic garbage tend to burn.

During the heating step, the vinyl waste and plastic waste pieces melt in a liquid state and permeate between the particles of the mixture to act as an adhesive. At this time, the animal waste mixed with the liquid between the main materials is 85 ~ 95% Is also evaporated, it also acts as an adhesive to improve the moldability in the following fifth step.

The food garbage is carbonized and charred like the charcoal by heating, so that it does not decay for a long time, and odor and gas are not generated.

Step 5 (extrusion molding and cutting step of the mixture)

In the fifth step S500, when the mixture passing through the fourth step is extruded into a predetermined shape when passing through the nozzle forming part 150, the extruded molded product is cut into a predetermined size at the cutting part 160 to be.

In the extrusion molding, the vinyl and plastic liquid melted in liquid form and the animal manure hardened by moisture evaporation act as adhesives between cutting particles of general household waste including food waste, so that the molding is hardened hardly, Is kept very good.

That is, the molded product is cut into a certain size such as a briquette to form a favorable form of the alternative fuel. The alternative fuel molding has residual molding heat at a considerable temperature and contains a little moisture.

Step 6 (curing drying step)

In the sixth step S600, the molding heat remaining in the molding cut to the predetermined size is dissipated from the drying curing part 170, and is cured to maintain the molded shape, and the moisture remaining in the molding is completely dried To complete the alternative fuel.

The curing and drying of the molded article may be performed from the outside with general natural wind at room temperature, but it takes time to cure and dry, so that it is preferable to provide a drying chamber equipped with hot air and a cooling fan to rapidly cure and dry.

In the present invention, 85 to 95% of the moisture of the mixture is evaporated at the heating step of melting the plastic waste or plastic waste before extrusion molding, and the remaining moisture is removed at the last curing and drying step.

According to the present invention, the alternative fuels made of general household waste including food waste can be used as fuel, such as vinyl garbage, plastic garbage, and carbonized food garbage, which are melted and absorbed in a liquid phase, And chemical additives are not required.
