[0031] The application of one aspect of this embodiment is as follows: when the filter device 1 is in use, the petroleum crude oil is introduced into the filter cartridge 4 inside the filter device 1 through the introduction pipe 20, and the squeezing mechanism 16 is turned on by the switch to push forward and squeeze the petroleum crude oil. When the petroleum crude oil is squeezed, the liquid will be discharged through the mesh holes on the upper side of the filter cartridge 4, and the solid waste will continue to be pushed forward. When the solid waste accumulates to a certain amount, it will drive the tightening mechanism 7 to contract, thereby discharging the waste generated by the filtration through the discharge barrel 10, and the filtered crude oil will be introduced into the collection tank 14 and then discharged through the outlet pipe 15. During the filtration process, the cooling mechanism 21 can cool the end of the filter cartridge 4 to avoid high temperature and greater wear. The filter device 1 can increase the filtration area of ​​the crude oil and improve the filtration efficiency of the crude oil through the double barrel setting of the feed barrel 2 and the filter cartridge 4, and the crude oil is squeezed by the squeezing mechanism 16 to increase the pressure on the crude oil and improve the separation efficiency between the crude oil and the solid waste.

[0032] In this embodiment, the extrusion mechanism 16 is composed of an extrusion screw rod 3 and a power mechanism 19. The extrusion screw rod 3 is rotatably installed in the inner position of the feeding barrel 2. One end of the extrusion screw rod 3 passes through the feeding barrel 2 and is installed at the front end position of the power mechanism 19. The power mechanism 19 is installed on one side of the feeding barrel 2. When the extrusion mechanism 16 is in use, the extrusion screw rod 3 is driven to rotate by the power mechanism 19. The extrusion screw rod 3 will push the petroleum crude oil forward during the rotation. During the pushing process, as the blade pitch between the extrusion screw rods 3 and the diameter of the central axis increase, the pressure on the crude oil increases, and the solid and liquid can be squeezed and separated.

The circulation pipe 5 is installed at the outer side of one end of the feeding barrel 2, the outer shell 13 is installed at the outer side of the circulation pipe 5, and the connecting pipe 6 is installed at both ends of the circulation pipe 5. When the cooling mechanism 21 is in use, the cooling water is introduced into the circulation pipe 5 through the connecting pipe 6. The coolant entering the circulation pipe 5 will cool the inside of the feeding barrel 2. After absorbing heat, the cooling water is discharged through the connecting pipe 6 for cooling.

[0036] In this embodiment, a heat insulation board 12 is arranged inside the shell 13, and the heat insulation board 12 is fixed inside the shell 13 by bolts. The arrangement of the heat insulation board 12 can increase the heat insulation effect of the shell 13 and prevent the external temperature from affecting the inside of the cooling mechanism 21 during use.
