[0027] Reference Figure 1 As shown, this utility model provides a technical solution: a multi-stage oil mist collector, including a collection box 1, a side plate 2 detachably installed on the side wall of the collection box 1, a primary pre-filter plate 3, a secondary primary filter screen 4 and a tertiary oil mist filter cotton 5 fixedly installed on the inner side of the collection box 1, a cotton cloth filter screen on the surface of the primary pre-filter plate 3, a shaking structure 6 on the surface of the collection box 1, and an installation structure 7 on the surface of the collection box 1.

[0028] The specific settings and functions of its shaking structure 6 and mounting structure 7 will be explained in detail below.

[0029] Reference Figures 1-4As shown in this embodiment: the shaking structure 6 includes a rectangular frame 601 connected to the upper surface of the collection box 1. A slider 605 is slidably connected to the inner side of the rectangular frame 601. A connecting rope 611 is fixedly connected between the slider 605 and the filter screen on the surface of the primary pre-filter plate 3. By setting the shaking structure 6, the filter screen on the connecting rope 611 can be shaken by sliding the slider 605, which can shake off impurities stuck on the filter screen, thereby improving the performance of the primary pre-filter plate 3. A folded tube 602 is fixedly connected to the side wall of the rectangular frame 601. The other end of the folded tube 602 is fixedly connected to the connecting shell 603. The folded tube 602 on the side wall of the rectangular frame 601 can move and extend with the slider 605 to avoid structural jamming. A first rectangular block 606 is fixedly connected to the upper surface of the rectangular frame 601, and a second rectangular block 607 is fixedly connected to the upper side of the connecting shell 603. A drawer plate 608 is slidably connected inside the second rectangular block 607, and the drawer plate 608 is fixedly connected to the surface of the first rectangular block 606. The first rectangular block 606, the second rectangular block 607, and the drawer plate 608 cooperate to adjust the movement range of the slider 605. A bolt 609 is threadedly connected inside the second rectangular block 607. Several insertion holes 610 are formed on the surface of the drawer plate 608, and the size of the insertion holes 610 is adapted to the size of the bolts 609. The bolts 609 are inserted into different insertion holes 610 on the surface of the drawer plate 608 to fix the position of the drawer plate 608 and ensure that the vibration amplitude is controllable. A drive rod 604 is threadedly connected inside the connecting shell 603, and the drive rod 604 is rotatably connected to the slider 605. Rotating the drive rod 604 can drive the slider 605.

[0030] Reference Figures 1-2 and Figures 5-6 As shown, specifically, the mounting structure 7 includes four pins 74 fixedly connected to the side wall of the collection box 1, and the side plate 2 slidably connected to the surface of the four pins 74. The side plate 2 can be quickly removed through the mounting structure 7. The pins 74, which are slidably connected to the surface of the four pins 74 on the side wall of the collection box 1, serve as positioning guides. Two mounting blocks 71 are fixedly connected to the side wall of the collection box 1. A retaining frame 72 is slidably connected inside the mounting block 71. The retaining frame 72 has a rectangular ring structure, and a sloped structure is provided on the side of the retaining frame 72 away from the collection box 1. A spring 73 is fixedly connected between the retaining frame 72 and the mounting block 71. The spring 73 between the retaining frame 72 and the mounting block 71 always provides elastic force, so that the retaining frame 72 locks the edge of the side plate 2. A sealing gasket 75, which has a rectangular ring structure, is glued to the surface of the collection box 1. The rectangular annular sealing gasket 75 on the surface of the collection box 1 can fill the gap after the side plate 2 is installed, preventing unfiltered oil mist from leaking from the connection between the side plate 2 and the collection box 1, thus ensuring the sealing performance of the equipment.

[0031] Working principle: During long-term filtration, impurities easily get stuck on the filter screen of the primary pre-filter plate 3, affecting filtration efficiency. This problem can be solved by operating the shaking structure 6. Rotating the drive rod 604 inside the connecting shell 603 causes the drive rod 604 to rotate and connect with the slide bar 605, causing the slide bar 605 to slide inside the rectangular frame 601. The slide bar 605 is connected to the filter screen via a connecting rope 611. The sliding of the slide bar 605 pulls the connecting rope 611, causing the filter screen to shake. At the same time, the folded tube 602 on the side wall of the rectangular frame 601 can extend and retract with the movement of the slide bar 605, avoiding... Without structural jamming, the first rectangular block 606 and the second rectangular block 607 cooperate with the pull plate 608 to adjust the movement range of the slide bar 605. The bolt 609 is inserted into different holes 610 on the surface of the pull plate 608 to fix the position of the pull plate 608, ensuring that the shaking amplitude is controllable. Ultimately, it can shake off the impurities on the filter screen and maintain the filtration performance of the first-stage pre-filter plate 3. By setting the shaking structure 6, the filter screen on the connecting rope 611 can be shaken by sliding the slide bar 605, which can shake off the impurities stuck on the filter screen, thereby improving the performance of the first-stage pre-filter plate 3.

[0032] When it is necessary to replace or clean the filter components at each stage, the side plate 2 can be quickly removed through the mounting structure 7. The side plate 2 is slidably connected to the surface of four pins 74 on the side wall of the collection box 1. The pins 74 serve as positioning guides. A retaining frame 72 is slidably connected inside the mounting block 71 on the side wall of the collection box 1. The spring 73 between the retaining frame 72 and the mounting block 71 always provides elastic force, so that the retaining frame 72 locks the edge of the side plate 2, thereby fixing the side plate 2. When disassembling, pull the retaining frame 72 away from the collection box 1, and the spring 73 will compress. When the clip 72 is disengaged from the side plate 2, the side plate 2 can be removed along the direction of the pin 74. In addition, the rectangular annular sealing gasket 75 on the surface of the collection box 1 can fill the gap after the side plate 2 is installed, preventing unfiltered oil mist from leaking from the connection between the side plate 2 and the collection box 1, thus ensuring the sealing performance of the equipment. By setting the installation structure 7, the side plate 2 can be flexibly installed using a locking mechanism, which facilitates the subsequent regular maintenance of the primary pre-filter plate 3, the secondary primary filter screen 4, and the tertiary oil mist filter cotton 5.
