The input waste oil flows through the other end of the oil inlet filter, and a detachable filtering and crushing mechanism is provided in the other end to play a filtering role. The crushing effect is adopted when too much internal residue accumulates and causes poor oil extraction. The large internal residue is crushed so that the waste oil can be continuously pumped in. The filtered waste oil enters the gear pump 14 through the oil inlet docking end, enters the oil outlet pipe 19 through the oil outlet end of the gear pump 14 and docks with the output pipe, and the waste oil is input into the storage barrel.

[0036] The protective member includes a bottom connecting frame 3 fixedly connected to the lower end of the rectangular shell 1, and the side of the bottom connecting frame 3 is fixedly connected to the side connecting plate 4 through a plurality of connecting cross bars. A rectangular groove is opened at the upper end of the side connecting plate 4, and a limit plate 13 is fixedly connected in the rectangular groove. The limit plate 13 is sleeved on the outer side of the oil outlet pipe 19 to realize the limiting fixation of the oil outlet pipe 19.

[0037] The bottom connecting frame 3 protects the oil inlet docking end and the oil inlet filter. The side connecting plate 4 is connected to the bottom connecting frame 3 as a whole. When pumping oil, the bottom end can be placed on the oil drum for use, without the need for handheld operation, thus saving manpower.

The oil inlet filter includes a vertical tube body 17 arranged vertically, and the side of the vertical tube body 17 is fixedly connected to an inclined tube body 18, and the vertical tube body 17 and the inclined tube An oil inlet 28 is provided at the connection of the body 18, the inclined tube body 18 is inclined, and the angle between the inclined tube body 18 and the vertical tube body 17 is 30°-60°, and the filtering and crushing mechanism is installed at the bottom end of the vertical tube body 17, and the filtering and crushing mechanism includes a sealing end 11 that is sealed and screwed with the lower end of the vertical tube body 17, and a micro motor 25 is arranged inside the sealing end 11, and the output end of the micro motor 25 is docked with a crushing piece, and the inside of the crushing piece is rotatably connected with a filter element, and the upper end of the filter element is docked with the positioning protrusion to achieve positioning.

[0039] Please refer to Figure 1 , 2 3. The filter element includes a filter screen cylinder 24 rotatably connected to the crushing element, the upper end of the filter screen cylinder 24 is fixedly connected to the docking end 23, a filtering space is formed between the docking end 23 and the vertical tube body 17, the upper end of the vertical tube body 17 is arranged above the oil inlet 28, so that the waste oil entering through the oil inlet 28 flows from the filtering space below and enters the inside of the oil inlet plate 16 through the filter screen cylinder 24, the crushing element includes a connecting seat 26 fixedly connected to the output end of the micro motor 25, and a plurality of vertical strip grooves are opened on the side of the connecting seat 26, and a spiral blade 27 is fixedly connected to the outer side of the connecting seat 26.

[0040] Suction is generated by the gear pump 14, and waste oil is sucked in through the oil suction pipe 9. The sucked waste oil enters through the inclined tube body 18 and the oil inlet 28. Due to the shielding effect of the docking end 23, the waste oil passes through the filter space and enters through the vertical strip groove on the side of the connecting seat 26, and is filtered by the filter screen cylinder 24. The residue is filtered on the outside of the connecting seat 26. The spiral blade 27 on the outside of the connecting seat 26 plays a partial role.

The lower end of the docking protrusion 21 is fixedly connected with a positioning magnetic ring 22, and the positioning magnetic ring 22 is magnetically connected to the docking end 23 to achieve positioning.

[0043] The positioning magnetic ring 22 is magnetically positioned with the butt end 23 at the upper end of the filter screen cylinder 24, so that the filter screen cylinder 24 can remain relatively stable when the connecting seat 26 and the spiral blade 27 rotate and crush.

[0044] A control panel 5 is installed on the side of the rectangular housing 1 , and the control panel 5 is electrically connected to the gear pump 14 and the micro motor 25 . The control panel 5 , the gear pump 14 and the micro motor 25 are connected to an external power source through wires.

[0045] The whole device can be fixed through the control panel 5, and the power supply of the whole device is used through an external power supply through a wire, or a built-in battery can be used outdoors. The battery can be placed inside the top connection frame 2.

[0046] Embodiment 2, in actual use, valves can also be set on the oil outlet pipe 19 and the inclined tube body 18. The valves can be manual valves or solenoid valves. The use of solenoid valves makes it easier to operate. The oil inlet pipe 15 can also be equipped with a flow regulating valve to regulate the oil intake.
