Then, the can 71 is placed in the box 51 of the compressing device 5 and located under the compression disk 54. Then, the control valve 57 is started to control the pneumatic pump 55 to drive the piston rod 53 to move outward to move the compression disk 54 toward the can 71 so as to compress the can 71 as shown in FIG. 15. Finally, the compressed can 71, the bottom plate 72, the filter unit 73, the upper cover 75, the lower cover 74 and filter net 76 are collected and processed respectively.
Accordingly, all of the parts of the used engine oil filter 7 can be divided and reused respectively, thereby efficiently achieving the resource recycling purpose, and thereby preventing the used engine oil filter 7 from causing environmental pollution.
