[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-7 The utility model provides a technical solution: a waste lubricating oil recycling and regeneration production device, including a filtering and processing box 1, a adding port 2, a fixed cylinder 3, a fixed bracket 4, an electric telescopic rod 5, a movable plug 6, a connecting mechanism 7, a movable plate 8, a protrusion 9, a filter screen 10, a fixed block 11, a support block 12, a limit plate 13, a spring 14, a movable column 15, a pull rod 16 and a valve 17.

[0033] When using the waste lubricating oil recycling and regeneration production device, if Figure 1 , Figure 2 and Figure 3 As shown, an addition port 2 is provided at the upper left end of the filtering and processing box 1, and waste lubricating oil is added to the inside of the filtering and processing box 1 through the addition port 2. After the addition is completed, the addition port 2 is blocked by engaging the external cover plate in the addition port 2, and the waste lubricating oil is filtered through the filter screen 10, and then the valve 17 installed at the lower end of the filtering and processing box 1 is opened, and the filtered lubricating oil is discharged downward through the valve 17, and then the filtered lubricating oil is collected through the container. At the same time, during the filtering process, the electric telescopic rod 5 installed in the middle of the fixed bracket 4 is started, and the electric telescopic rod 5 drives the movable plug 6 to move slowly downward. The movable plug 6 is fitted on the inner side wall of the fixed cylinder 3, thereby increasing the pressure in the filtering and processing box 1, thereby increasing the filtering speed of the waste lubricating oil through the filter screen 10, and greatly improving the actual filtering and processing efficiency of the waste lubricating oil;

The movable plug 6 drives the movable plate 8 to move outside the fixed bracket 4, and the movable plate 8 slides between the protrusion 9, thereby improving the stability of the movable plug 6 in the telescopic movement inside the fixed cylinder 3. When the filtering process is completed, as shown in FIG. Figure 5 , Figure 6 and Figure 7 As shown, by pulling the pull rod 16 downward, the pull rod 16 moves with the limit plate 13, and the pull rod 16 drives the movable column 15 to slide with the limit plate 13. At this time, the movable column 15 squeezes the spring 14, causing the spring 14 to undergo elastic deformation, and the movable column 15 is disengaged from the fixed block 11, thereby releasing the limit between the fixed block 11 and the limit plate 13, and then flipping the limit plate 13, the limit plate 13 is flipped on the support block 12, and the limit plate 13 is disengaged from the fixed block 11, thereby releasing the limit between the filter screen 10 and the filter treatment box 1, and then the filter screen 10 is pulled out of the filter treatment box 1, so as to facilitate the disassembly and cleaning of the filter screen 10 to prevent the filter screen 10 from being blocked during long-term use.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
