≪ RTI ID = 0.0 > [0001] < / RTI > A regenerated fuel manufacturing equipment having a waste aspiration structure for treatment,

The present invention relates to a regeneration fuel production apparatus for molding combustible wastes among general wastes such as households and industrial wastes by densification through firing and compression processes, And more particularly to a regeneration fuel production apparatus provided with a waste aspiration structure for treatment of an improved production apparatus for regenerated fuel.

Regenerative fuels of flammable wastes are subjected to a predetermined sorting process in various wastes such as households or industrial wastes to burn and dry flammable wastes that have been removed from incombustible wastes or metals, It is a solid fuel made.

The apparatus for producing such a combustible regenerated fuel is mainly a high-temperature firing and extrusion molding system, in which flammable wastes introduced through a hopper are placed in a superheated case of a heat-generating unit, Through the use of a ribbon screw shaft equipped with an auxiliary heating unit that helps the pyrolysis and firing of the inner side of the combustible waste while the heating medium is forcibly circulated by a separate heater in a tubular shape, it is conveyed, sintered and compressed, And is molded into a regenerated fuel solidified by a series of extrusion equations. At this time, the regenerated fuel is extruded into a rod shape, cut into a suitable length by using a separate cutting device, and is produced in the form of a lump using a pellet-type or roll-forging method.

However, in this apparatus for producing reclaimed fuel, flammable wastes supplied by the free fall method by its own weight are not constantly introduced into the case, that is, empty threaded bolls are not filled because the flammable waste is not supplied to the screw thread of the ribbon screw shaft. The supply of flammable waste becomes uneven due to a phenomenon in which the waste is not introduced into the ribbon screw shaft and idling occurs. Therefore, such uneven supply is fatal to the densification of the product and bubbles occur, leading to deterioration of the quality of the regenerated fuel .

Thus, the waste introduced into the hopper through the lower side of the hopper is supplied to the side of the ribbon screw using the pusher of the pressurizing type. However, the waste toner is not completely prevented from being filled with the flammable waste, The inner diameter of the inlet end is closely adjacent to the outer diameter of the ribbon screw shaft, and thus the adjacent inlet end has many problems such as jaw catching phenomenon, and the incoming waste does not enter the ribbon screw shaft, to be.
