Hereinafter, the operation process of the solid fuel production apparatus using the household waste according to the present invention configured as described above and the solid fuel production method using the household waste will be described in detail.

First, when the ruckle crane 10 is operated to inject the household waste into the inlet 12, the household waste is transported on the first conveyor belt 14. At this time, the electromagnet 16 mounted on the upper part of the first conveyor belt 14 separates the ferrous metal mixed in the household waste.

Thereafter, the municipal waste from which the ferrous metal is separated is coarsely crushed while passing through the first crusher 20, and then crushed in the middle while passing through the second crusher 22, and is then heated by the second conveyor belt 24. Is transferred to).

The household waste conveyed to the heating compressor 30 is transported by the conveying screw 34 of the compression pipe 32, and at the same time, the household waste is at least 10% or more of moisture by the heat generated by the electric heating unit 36. As it decreases, it has a uniform moisture content.

Thereafter, the household waste having a uniform moisture content is crushed in the third crusher 40 mounted on one side of the heating compressor 30 and then transported on the third conveyor belt 42.

The living waste conveyed on the third conveyor belt 42 is crushed again by the fourth crusher 50 and then transported to the scattering cutting type rotary dryer 60 by the fourth conveyor belt 52.

The household waste conveyed to the scattering cutting rotary dryer 60 is introduced into the rotary drum 62 by the input screw 64 to be rotated by the rotational force of the rotary drum 62.

At this time, the living waste rotated along the rotary drum 62 is transported while being finely cut by the cutting blade 66 and the auxiliary cutting blade 67 of the scattering cutting assembly 65 which is mounted on the rotary shaft 63 and rotates at high speed. At the same time, the domestic waste is dried by hot air discharged from the hot air blower 68.

In this way, since the cutting blade 66 and the auxiliary cutting blade 67 for cutting household waste are inclined in a direction opposite to the rotational direction of the rotary shaft 63, the household waste is rotated on the blades 66 and 67 at the time of rotation. Can be prevented.

Thereafter, the finely cut and dried household waste is moved to the discharge screw 70 under the guidance of the air discharged from the guide blower 69, and the moved household waste is discharged through the discharge screw 70 to be conveyed to the fifth conveyor. The belt 72 is transported to the solid fuel molding machine 100.

The municipal waste conveyed to the solid fuel molding machine 100 is mixed with the neutralizing agent introduced from the neutralizing agent supply means 80.

That is, when the electric motor 87 whose rotation speed is adjusted by the inverter 88 rotates, the feeder screw 84 rotates by the rotational force, and the neutralizing agent in the neutralizing agent supply container 82 is fed to the feeder screw ( The hopper portion 85 and the discharge portion 86 of the 84 is transferred to the vibrating net 89 in a state where the pressure is reduced, and the transferred neutralizer is evenly mixed with the household waste by the vibration of the vibrating net 89. .

The neutralizer added as described above neutralizes the acid gas generated when the solid fuel 110 is burned.

In addition, the calorific value of the solid fuel 110 may be increased by selectively mixing the waste plastic crushed in the neutralizing agent mixing vessel.

Thereafter, the domestic waste mixed with the neutralizing agent is transferred to the end face shrinkage compression section 91 by the forming screw 93 in the forming tube 92, and the endowment waste passing through the end face shrinkage compression section 91 is a temperature control section 97. Moisture is completely removed by the heat emitted from the electric heating wire 95 set at a predetermined temperature by the < RTI ID = 0.0 >), < / RTI > The inner hole 112 is formed to have a shape as the solid fuel 110.

At this time, the temperature control unit 97 serves to prevent the loss of energy because the temperature of the electric heating wire 95 can be adjusted according to the state of the molding process, the heat insulating material 96 on the outside of the electric heating wire 95. Because it is covered, it not only prevents heat loss but also improves molding performance.

Subsequently, when the domestic waste mixed with the neutralizing agent passes completely through the cross-sectional shrinkage compression unit 91, the solid fuel 110 in which the internal holes 112 are formed is generated, and the internal holes 112 of the formed solid fuel 110 are burned. It acts as a passage for air, and thus serves to improve combustion performance.

As described above, the present invention has the effect of energy reproduction and environmental preservation by manufacturing household waste into a solid fuel of high heat emission without pollution through a multi-step process.

Although the present invention has been described above using embodiments of the present invention, it will be apparent to those skilled in the art that various modifications may be made without departing from the spirit of the present invention.
