(6) According to the waste recycling plant according to the fourth aspect, as a sorting machine, processing is performed on a sorting block in which a plurality of rotating rotors in which a plurality of large and small rings are alternately arranged in the axial direction are arranged in a plurality of inclined shapes. A slanted rotor sorter that sorts the material into at least three types of material that has passed through the sieve, the material that has fallen downward, and the lightweight material that has been conveyed upwards is used. , And continuously sorted into three types: a material passing through a sieve, an upper conveyed lighter weight product, and a lower falling weight material. That is, paper, sheet, plate, PE that does not pass through a sieve
Light objects such as T-bottles are conveyed upward, heavy objects such as stones, cans and metal pieces that do not pass through the screen fall down, and small objects such as earth and sand, leftovers and crushed fruits that pass through the screen are removed. It can drop from the sorting block without clogging and can be sorted into three types. Furthermore, if the inclination of the sorting block can be adjusted, the branch point between the light and heavy objects can be moved and set according to the type of waste. (7) According to the waste treatment plant according to the fifth aspect, as a sorting machine, a processed material is placed on a sorting block in which a plurality of rotating rotors in which a plurality of large and small rings are alternately arranged in the axial direction are horizontally arranged. We use a horizontal rotor sorter that separates at least two types of materials into a sieve passing material and a conveyed material, such as paper, sheets, plates, PET bottles, etc. For waste mixed with spoiled fermentation products such as leftovers and garbage, a large amount of continuous and large quantities of lightly conveyed material can be produced without vibration in a relatively small installation place without any clogging. It can be sorted into two types. (8) According to the waste recycling plant according to claim 6, the sorting machine is provided with a push-up section that pushes up the rotor at the intermediate portion of the sorting block to invert the processed material, and the inside of the opened bag. The solidified garbage can be disintegrated well and scattered on the sorting block to increase the sorting accuracy.

And a preheating stirrer that heats and stirs a light weight object after removing aluminum by a fixed amount, so that the aluminum sorting machine can collect aluminum resources that consume a large amount of electric power during manufacturing. (11) According to the waste recycling plant of the ninth aspect, the preheating stirrer is constituted by a screw press crusher that receives the supply of the conveyed material, crushes and kneads with a spiral, pulverizes with a mortar pressing unit, and generates heat by compression. Even if the crushed material becomes wet with putrefactive fermentable waste such as garbage, the size of the crushed material used as solid fuel can be made uniform and the temperature can be increased by the heat of compression without heating from the outside. Drying equipment can be miniaturized and energy consumption can be reduced. (12) According to the waste recycling plant according to the tenth aspect, the preheating stirrer has a structure capable of receiving and mixing and agitating quick lime supplied from another quantitative feeder by a fixed amount, and the preheat stirrer is supplied from the quantitative feeder. It is possible to receive and mix the quicklime supplied in increments and preheat it by the chemical reaction of quicklime and moisture, and to appropriately increase the ash content to appropriately suppress the calorific value of solid fuels including plastics with dislikes that are too high with a preheating stirrer. . Further, quick lime can absorb chlorine contained in vinyl chloride and the like, thereby preventing generation of chlorine gas at high temperatures. In addition, the pre-heating of the chemical reaction between quicklime and water can be used to eliminate the subsequent dryer. (13) According to the waste recycling plant according to claim 11, as a subsequent device of the preheating stirrer, a dryer combined with a hot air generator is provided, and a dryer combined with the hot air generator is provided, It is possible to reliably remove the moisture that inhibits the solidification of the fuel in the solid fuel molding machine for the processing that is wet with moisture coming from garbage and the like.
