And it moves to the second washing space (B) through the gap between the second end portions 67 of the second plate. The waste vinyl introduced into the second washing space (B) is stirred for a certain period of time. And it moves to the third washing space (C) through the gap between the second ridges of the third plate. In this way, the fourth and fifth washing spaces D and E are sequentially moved, and finally discharged to the outside through the discharge pipe 15.

In this way, the waste vinyl introduced into the washing container is uniformly maintained for a certain period of time, and is sequentially moved and washed, so that foreign matters such as soil attached to the waste vinyl can be effectively removed.

The foreign substance discharge means is installed under the washing container 20 and is installed on the bottom of the foreign substance collection tank 70 and the foreign substance collection tank 70, which gradually narrows the distance therebetween, and a screw conveyor that transports foreign substances to the outside. It is provided on the outside of the housing (73) and the housing 10, the discharge casing (75) is inserted into one side of the screw conveyor (73). The discharge casing 75 is formed with a discharge port through which foreign substances are discharged.

The debris collection tank 70 is made of a structure opened toward the top. Therefore, foreign substances such as soil separated from the waste vinyl in the washing container 20 settles downward and accumulates on the bottom of the foreign substance collection tank 70. When the screw conveyor 73 rotates, the foreign matter accumulated on the floor moves toward the discharge casing 75 and is discharged to the outside through the discharge port.

An electric motor 77 is installed to rotate the screw conveyor 73. The pulley 78 coupled to the screw conveyor 73 and the electric motor 77 are connected by a belt 79.
