At this time, a first storage tank 110, in which waste is stored, may be connected to the front end of the barb 120. The first storage tank 110 serves as a buffer for waste movement, Take a structure that can store large quantities of waste. The first storage tank 110 is formed with a first inlet 110a as a portion into which waste is drawn. In addition, a first crane 110b for gripping and moving the waste to move the internal waste to the next stage, and a first adjusting chamber 110c for adjusting the first crane 110b are installed.

The first storage tank 110 may be connected to the first storage tank 110 sequentially through a leachate settling tank 111 and a leachate storage tank 112. At this time, the leachate settling tank (111) is a water tank in which the water leached from the waste flows into the tank, and the leachate storage tank (112) is a tank for storing the leached water from which the precipitate is removed. In addition, the leachate storage tank 112 may be connected to the flow rate adjusting tank so that the leachate can flow when the stored amount exceeds the predetermined storage amount. In the leachate flow between the leachate settling tank 111 and the flow rate adjusting tank, .

The breaker 120 includes a breaker hopper 121 for receiving the waste wrapped by the seal member, a breaker 122 provided in the breaker hopper 121 to break the seal member, and a breaking hopper 121 And a quantitative feed conveyor 123 for quantitatively feeding waste into the feed conveyor 123. At this time, the sealing member is collectively referred to as a plastic bag for wrapping the waste, a member for partially or totally sealing the waste such as a string to bind the waste in a certain amount.

Here, the breaking hopper 121 is disposed inside the rear end side of the first storage tank 110, and this breaking hopper 121 guides the waste held by the first crane 110b securely to the conveyor .

Here, the breaking-off blade 122c includes a blade body B having a rotation shaft 122b fitted therein, and a plurality of blade cutters C projecting radially from the blade body B and linearly extending and projecting from the blade body B .

Specifically, the protruding length of the radial blade cutter C from the blade body B may be designed to be smaller than the distance from the center of the rotating shaft 122b to the outer circumferential surface of the radial blade body B, Since it is intended to break the sealing member of the waste rather than crushing the waste passing through the pipe 122.

The distance between the end of the blade cutter C mounted on the one rotary shaft 122b and the rotary shaft 122b on the other side is larger than the projecting length of the radial blade cutter C from the blade body B, 122b may be designed to be smaller than the protruding length of the radial breaking-breaking blade 122c by increasing the distance between the end of one blade edge and the rotational axis 122b of the other blade edge by a predetermined distance or more , The waste passing through the breaker 122 is scarcely broken and only the sealing member of the waste breaks.

At this time, the steel material among the contaminants can be sold again, and other objects can be recycled according to the use.

In addition, a second storage tank 140 may be connected to a rear end of the sorting and crushing unit 130 to store the crushed waste to be stored therein.

Specifically, the second storage tank 140 functions as a buffer for the movement of the waste in the path along which the waste is sorted and crushed as described above, and a structure capable of storing a large amount of waste therein is provided. The second reservoir 140 is formed with a second inlet 140a as a portion into which the waste is introduced. In addition, a second crane 140b for holding and moving the waste to move the internal waste to the next stage, and a second adjusting chamber 140c for adjusting the second crane 140b are installed. In addition, a storage hopper 140d is disposed inside the rear end side, and this storage hopper 140d guides the waste held by the second crane 140b to be safely secured to the conveyor.

For reference, the waste can be moved by a conveyor as shown in the figure in order to sequentially move the respective components of the above-described crushing and sorting unit 130, without being limited by the present invention, It is needless to say that any conventional transportation member such as a bogie can be utilized.

In the course of drying the waste, The harmful gas generated is separated and then released to the atmosphere. For reference, the path through which the noxious gas moves in the drying unit 150 is moved through the duct as shown in the figure.

The quantitative feeder 154 serves to quantitatively supply waste discharged from each of the dryer 152 and the dust collector 153a. The waste supplied to the dryer 152 and the dust collected by the dust collector 153, And receives the waste and supplies it to the gasification furnace 210 in the next progress stage by a predetermined amount.

As a result, in order to increase the contact area and increase the amount of heat when the fuel is used as fuel in waste such as household waste, wood chips, bio materials, etc., It acts to remove residual water after pulverizing the remaining waste.

Thus, the fuel producing means 100 has the advantage that the waste heat can be processed into a non-forming solid fuel of low calorific value so that the waste can be used in the gasification furnace 210 of the next process.
