DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a method for recycling a waste plastic according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a process of a waste vinyl recycling method according to the present invention in order.

As shown in the drawings, the present invention can recycle various kinds of fertilizer collected in rural areas or a plastic bag containing feedstuffs or compost, and is mainly composed of a wet grinding step, a first washing step, a first dewatering step, 2 washing steps, a second dewatering step, a drying step, a melting step, an extrusion step, a cooling step and a chip forming step.

Therefore, in the present invention, first, the vinyl or vinyl bag collected by using the conveyor is supplied to the pulverizer, and the pulverizer is supplied with the washing water from the upper part thereof, so that the foreign substances attached to the vinyl or the vinyl bag to be supplied are separated So that the pulverization of the vinyl can be performed at a predetermined size.

The pulverized vinyl pulverized material is dropped to the bottom of the pulverizer by the washing and pulverizing of the vinyl material by water supply, and the dropped vinyl pulverized material is conveyed to the first washing means by the screw driving of the first conveying means.

Since the vinyl crushed materials supplied to the first cleaning means are attached with many foreign substances such as soil, they are moved through the transfer screw of the first cleaning means while being cleaned by the washing water supplied from the upper portion, Make sure that it is discharged downward through a string.

The first cleaning means is formed so as to be inclined at a predetermined angle so that the cleaning water is supplied to the vinyl crushed materials moving upward by the screw so that the foreign materials are separated from the vinyl crushed materials and discharged downward through the bottom clamping net, The vinyl crushed material can be stably moved upwards by the driving of the feed screw.

The vinyl mills which are cleaned by the first cleaning means and move upward are supplied to the first dehydrator to perform dehydration.

The first dehydrator is provided with a cylindrical net, which is rotatably provided in the first dehydrator, to supply the cleaned vinyl crushed material, and the cylindrical net is rotated so that the foreign materials attached to the vinyl crushed material are separated by the centrifugal force and discharged to the outside.

The dehydrated vinyl powders are supplied to the centrifugal separator by the blowing power of the blower. In the centrifugal separator, the vinyl impregnated products are descended downward while moving in a helical manner along the inner circumferential surface where the diameter gradually decreases downward.

In this case, foreign matter attached to the vinyl crushed material is separated by the action of downward movement from the centrifugal separator to the sprinkled vinyl, and falls to the lower tank.

The vinyl crushed material and the foreign substances separated from the centrifugal separator and supplied to the water tank are floated on the water surface by the water filled in the water tank, and the foreign substances are submerged. At this time, So that the rotation of the agitating blades causes the vinyl grindstones to float on the water surface to move.

That is, when the agitating blades of the water tank are rotated, the vinyl pulverized materials which are supplied to the water tank and floated on the water surface are moved to one side. At this time, the foreign materials attached to the vinyl pulverized materials are separated from the vinyl pulverized materials, do.

The vinyl crushed materials that have been washed through the water tank are placed on one end of a conveyor provided so that one end of the water tank is immersed in the water, and the vinyl pulverized material washed through the conveyor is supplied to the second dehydrator.

The second dehydrator is constructed in the same manner as the first dehydrator so that water is removed from the vinyl pulverizations received therein by centrifugal force.

The vinyl mills dewatered in the second dehydrator are dried while being moved by the wind power of the blower so that the wind power to be blown from the second dehydrator is stronger than the wind power to be blown from the first dehydrator desirable.

In other words, the vinyl pulverized material transferred from the second dehydrator is dried by the wind power.

The blast-dried vinyl mills are fed to an extruder and in an extruder, the vinyl mills being transported are melted by electric heating while being moved by an extrusion screw.

However, the vinyl crushed materials are melted in the kneaded state and extruded to a certain thickness by the extrusion screw.

The molten material thus melt-extruded is simultaneously extruded through a plurality of holes through a perforated plate nozzle having a predetermined diameter so as to be provided at the tip of the extruder while maintaining the molten state of the dough constant.

The extrudate to be extruded through the perforated plate nozzle is extruded through the diameter of the hole formed in the perforated plate nozzle and the number of the holes, and the extrudate to be extruded is cured while passing through the cooling water.

When the extrudate is cured and passes through the cooling water having a predetermined length, the extrudate is drawn upward so as to be naturally cooled and dried in the air.

Thus, depending on the temperature of the extrudate, the extrudate is allowed to pass through the cooling length by the cooling water or from the cooling water to allow the extrudate to pass over the optimum length for natural cooling and drying in the atmosphere.

The cooled and dried extrudate is passed through a cutter to allow the extrudate to be cut to a size that is easy to recycle, thereby forming a recycled chip.

Meanwhile, in the manufacturing process according to the present invention, the washing water discharged together with the foreign substances by the first washing step and the first dewatering step may remove the foreign substances while being subjected to the purification step, It is also possible to supply it.

Through this process, the waste vinyl is made to be easy to recycle, and at the same time, the components of the recycled chip are made more pure by the complete cleaning of the foreign materials.

That is, if a chip is manufactured by removing impurities, it is possible to obtain better physical properties in the field of recycling by using the chip.
