Dynamic connection, the bottom of the driving pulley 20 is fixedly connected with a threaded rod 13, the middle and upper outer part of the threaded rod 13 is threadedly connected with a movable plate 21, the left side of the movable plate 21 is fixedly connected with a pressure plate 14, the bottom of the pressure plate 14 is installed with a sealing ring 12, and the front side of the body 1 is provided with a cleaning mechanism 2; the right side of the movable plate 21 is fixedly connected with a slider 22, the left side of the inner wall of the fixed frame 17 is provided with a slide groove 18, and the slider 22 is slidably connected with the slide groove 18; the outer side of the arc tube 11 is fixedly connected with a fixing bolt 9, and the outer side of the fixing bolt 9 is threadedly connected with a connecting flange 10;

[0038] Specifically, during the operation of the entire equipment, the driving motor 19 plays a vital role; it drives the active pulley 20 to rotate, thereby starting the entire transmission system; the rotation of the active pulley 20 is transmitted to the driven pulley 15 through the connecting belt 16, so that the two rotate synchronously; this process makes full use of the stability and reliability of the belt transmission to ensure the stability and reliability of the equipment operation; while the active pulley 20 rotates, the threaded rod 13 also rotates; this design cleverly transmits the rotational power of the pulley to the threaded rod 13, and drives the movable plate 21 to move up and down; the movement of the movable plate 21 drives the pressure plate 14 to move synchronously, further realizing the coordinated work of various components inside the equipment ; In order to ensure the stability and safety of the movable plate 21 when it is lifted and lowered, a slider 22 and a slide groove 18 are also provided in the equipment; the slider 22 slides in the slide groove 18, which plays a limiting role and avoids excessive displacement of the movable plate 21 during the lifting and lowering process; at the same time, this design also plans a precise trajectory for the movement of the movable plate 21, ensuring the accuracy and reliability of the equipment operation; after the movable plate 21 moves to the appropriate position, the pressure plate 14 will be moved to the upper position of the end cover for sealing; at this time, the sealing ring 12 will seal the edge, effectively preventing medium leakage and greatly improving the sealing performance of the end cover; this design fully demonstrates that the equipment attaches great importance to safety and reliability while ensuring operating efficiency.

[0039] Reference Figure 1 and Figure 3 The cleaning mechanism 2 includes a connecting rod 202, the top of which is fixedly connected to the bottom of the driven pulley 15, the bottom of which is fixedly connected to a fixing block 203, the bottom of which is threadedly connected to a fixing plate 201 via a connecting bolt 204, the bottom of which is fixedly connected to a fixing column 205, and a cleaning brush 206 is installed on the outer side of the fixing column 205;

[0040] Specifically, first insert the fixing column 205 into the storage bucket, and then let the driven pulley 15 start to rotate; at this time, the connecting rod 202 will rotate synchronously with the fixing block 203; through this design, the fixing disk 201, the fixing column 205 and the cleaning brush 206 can rotate together; in this process, the cleaning brush 206 will effectively clean the inside of the storage bucket; the design advantage of this equipment is that it does not need to replace other equipment for cleaning work, thereby reducing production costs and improving work efficiency; when the cleaning brush 206 needs to be removed, only the connecting bolt 204 needs to be removed; this design makes cleaning work more convenient and greatly reduces maintenance costs.

[0041] Reference Figure 1The top of the machine body 1 is connected with an oil drain pipe 7; the front side of the machine body 1 is connected with a drain pipe 3, and a valve 4 is installed on the outside of the drain pipe 3; the front side of the machine body 1 is installed with a control button 8, and the control button 8 is electrically connected to the drive motor 19 and the machine body 1 respectively; the bottom of the machine body 1 is fixedly connected with legs 5 on all sides;

[0042] Specifically, the separated grease is discharged through the oil drain pipe 7, and at the same time, the valve 4 is opened to discharge the sewage through the drain pipe 3. Pressing the control button 8 can control the opening and closing of the machine body 1 drive motor 19 and the machine body 1. The equipment can be supported by the support legs 5, which increases the stability of the equipment.

[0043] Working principle: Turn on the driving motor 19 to drive the active pulley 20 to rotate. The rotation of the active pulley 20 drives the driven pulley 15 to rotate synchronously through the connecting belt 16. When the active pulley 20 rotates, the threaded rod 13 is also rotated, so that the movable plate 21 is driven to move up and down through the rotation of the threaded rod 13, so that the movable plate 21 and the pressure plate 14 are moved synchronously. When the movable plate 21 moves, the slider 22 is driven to slide in the slide groove 18, which is used for the limit work when the movable plate 21 is lifted and lowered. At the same time, the moving trajectory of the movable plate 21 is planned to move the pressure plate 14 to the upper side of the end cover. The square position is closed, and the sealing ring 12 seals the edge, thereby increasing the sealing performance of the end cover to meet the use requirements, and the fixing column 205 is inserted into the storage bucket. When the driven pulley 15 rotates, the connecting rod 202 and the fixing block 203 are rotated synchronously, so that the fixing disk 201, the fixing column 205 and the cleaning brush 206 are rotated synchronously, and the inside of the storage bucket is cleaned by the cleaning brush 206. There is no need to replace the equipment to clean the storage bucket. When the cleaning brush 206 needs to be removed, the connecting bolt 204 can be removed, which brings convenience to use.
