The present invention relates to an apparatus for removing fuel residues of waste plastic fuel tanks for automobiles, and more particularly, to impregnating waste plastic fuel tanks by using an inclined cylindrical continuous friction rotary washing machine and ultrasonic nucleic acid washing machine using a conveyor belt. The present invention relates to a fuel residue removal device for a waste plastic fuel tank for automobiles capable of removing fuel residues.

The process for recycling plastic fuel tanks in waste vehicles is similar to the general plastic recycling pretreatment process in that it undergoes shredding, ferrous and non-ferrous separation, and impurities removal.

The plastic fuel tank recycling process of the waste vehicle requires a process of removing fuel impregnated in the fuel tank, unlike a general plastic recycling pretreatment process.

In other words, the process in which the fuel residue removal device is used is the most essential process in the plastic fuel tank pretreatment process and removes the fuel residue in the waste plastic pulverized product.

The waste plastic resin from which the fuel residue is removed is eventually recycled to resin in pellet form through extrusion molding.

On the other hand, the existing fuel residue removal device is to perform a single process of the steam process, the air stripping and steam process, the mixing process of the hexane extraction process, and the supercritical carbon dioxide extraction process.

As such, the fuel residue is firstly removed from the fuel residue removing apparatus through an air stripping and steam process, and finally, the fuel residue is removed through the hexane extraction process.

That is, when the waste plastic fuel tank crushed product is put into the fuel residue removing apparatus, the fuel residue is removed by steam or hot air introduced from one side of the fuel residue removing apparatus, and the fuel residue After about four hours, the crushed powder is stored and discharged through the outlet.

Then, the hexane extraction process is performed, and the pulverized product is stored in the removal apparatus for 1 hour, and the remaining fuel residue is extracted and discharged using hexane.

However, when the fuel residue of the waste plastic fuel tank pulverization is removed by the conventional fuel residue removal apparatus, there are the following problems.

2) In the fuel residue removal apparatus, in the continuous treatment of the fuel tank pulverization, due to the characteristics of the apparatus, the pulverized substance from which the fuel residue has been removed and the pulverized substance not removed are simultaneously discharged, thereby reducing the efficiency of removing the fuel residue there is a problem.

3) Steam and air stripping and hexane extraction processes are suitable for batch or semi-batch forms, and there is a difficulty in controlling the reaction time in the continuous treatment of a large amount of fuel tank grinds.

4) Waste plastic fuel tank is not easy to remove because fuel is impregnated into the fuel tank due to long-term vehicle operation, and it is difficult to transfer hexane to extract fuel residue in the pore of crushed powder when hexane is extracted. There is a problem of lowering the removal efficiency.

The present invention has been made in view of the above, the fuel tank pulverized through the inlet of the upper left of the housing using a continuous friction rotary washing machine installed inclined with a propeller mounted inside and rotating in a cylindrical shape. And the fuel residue is first washed while the water rotates in opposition to the housing and the propeller, and the ultrasonic tank is mounted in the housing filled with hexane solution, and the fuel tank crushed material is transferred through the porous conveyor belt. The purpose of the present invention is to provide a fuel residue removal device for a waste plastic fuel tank for an automobile in which a hexane bubble generated by ultrasonic waves penetrates into pores of a fuel tank pulverization and removes fuel residues by using an ultrasonic hexane cleaner installed as a structure. There is this.
