In lubrication management, it is essential to strengthen the regular and scientific replacement of lubricating oil. Since every enterprise is equipped with a certain number of devices, a considerable amount of lubricating oil needs to be replaced every year, which we call "waste oil".

[0003] To reduce enterprise costs and minimize the environmental impact of waste oil, it is necessary to use waste oil recycling devices for recovery. For example, the patent number CN211570591U2 published on the China Patent Network is titled "A Waste Oil Purification Device". However, the existing waste oil recycling equipment has a relatively complex structure, occupies a large space, and cannot perform centralized and rapid separation and filtration of waste oil, thus affecting the waste oil treatment efficiency.

[0004] Therefore, it is necessary to design and modify the purification equipment for waste oil regeneration. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention aims to provide a waste oil regeneration purification device and its usage method, which has the advantage of rapid recycling and purification of waste oil. It solves the problems of existing waste oil recycling equipment having a complex structure, occupying a large space, and being unable to perform centralized and rapid separation and filtration of waste oil, thus affecting the efficiency of waste oil treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a purification device for waste oil regeneration and its usage method, comprising a housing;

[0007] The housing contains a collection box, and a filter element is located at the bottom of the collection box. The top of the filter element penetrates the collection box and extends into its interior. A bellows pipe is connected to the bottom of the filter element. An oil drain pipe is connected to the bottom of the housing. The end of the bellows away from the filter element is connected to the oil drain pipe. A bidirectional screw is located on the right side of the housing. The left end of the bidirectional screw penetrates the housing and is movably connected to it. Screw sleeves are threaded onto both the left and right sides of the surface of the bidirectional screw. A crank is movably connected to the surface of the screw sleeves via a pin. A connecting block is fixedly connected to the surface of the collection box. The side of the crank away from the screw sleeve is movably connected to the connecting block via a pin.

[0008] As a preferred embodiment of the present invention, a guide rod is fixedly connected inside the housing, the guide rod is located at the bottom of the bidirectional screw, and the screw sleeve is sleeved on the surface of the guide rod and slidably connected to the guide rod.

[0009] As a preferred embodiment of the present invention, a spring plate is fixedly connected to the inner side of the crank, and the side of the spring plate away from the crank contacts the inner surface of the housing, and the spring plate is elastic.

[0010] As a preferred embodiment of the present invention, a column is fixedly connected to the bottom of the inner wall of the housing, the top of the column penetrates through the collection box and extends into the interior of the collection box, and the collection box is slidably connected to the column.

[0011] As a preferred embodiment of the present invention, protective covers are fixedly connected to both sides of the threaded sleeve, and the side of the protective cover away from the threaded sleeve is fixedly connected to the inner surface of the shell, and the protective cover is elastic.
