In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] In order to better understand the purpose, structure and function of the utility model, the utility model is described in further detail below in conjunction with the accompanying drawings, which is an easily disassembled waste oil dehydration and separation device.

[0036] like Figure 1-Figure 3 As shown, the utility model is an easily disassembled waste oil dehydration and separation device, which is composed of a flotation machine 1. At the same time, the flotation machine 1 is set as an upper open structure, and a rotatable hollow main shaft 11 is also provided inside the flotation machine 1. As the hollow main shaft 11 rotates, the pressurized air can pass through the hollow main shaft 11 of the flotation machine 1, so the air inside the flotation machine 1 forms many extremely fine bubbles. In the process of rising to the water surface, the waste oil can be brought to the water surface due to the surface tension of the bubbles.

[0037] Then, the dirty oil on the water surface can be scraped into the foam collecting tank 12 provided on the front of the flotation machine 1 by the rotating scraper 3, which can facilitate the subsequent processing. On both sides of the upper side of the flotation machine 1, opposite rotating seats 16 are provided, and a rotating shaft 2 that can rotate is provided between the two opposite rotating seats 16. The scrapers 3 located on both sides of the rotating shaft 2 are connected by a docking rod 21, and one end of the docking rod 21 is fixedly connected to the outer peripheral surface of the rotating shaft 2. Therefore, when the rotating shaft 2 rotates, the scrapers 3 can be rotated through the docking rod 21 to continuously scrape the foam on the water surface.

[0038] A pulley 13 is provided at one end of the rotating shaft 2, and the pulley 13 and the rotating shaft 2 are fixed by a pin shaft, and a driving component 14 is also provided on one side of the pulley 13, and a corresponding power transmission is formed between the driving component 14 and the pulley 13 through a belt 15. As the driving component 14 rotates, the pulley 13 can be rotated through the belt 15, and then the rotating shaft 2 can rotate together.

[0039] like Figure 3-Figure 5 As shown, a hollow cavity 22 is provided inwardly at one end of the rotating shaft 1 2, and a rotating shaft 2 5 capable of rotating independently is provided inside the hollow cavity 22, and a friction ring 23 is provided between the middle of the inner ring wall of the hollow cavity 22 and the outer peripheral surface of the rotating shaft 2 5, and the friction ring 23 can prevent the rotating shaft 2 5 from rotating by inertia. At the same time, the outer peripheral surface of the rotating shaft 1 2 is symmetrically penetrated along the middle on both sides, and the outer peripheral surface of the rotating shaft 2 5 is threadedly connected with a threaded sleeve 4, and the outer peripheral surface of the threaded sleeve 4 is provided with connecting arms 41 extending to the outside of the limiting slot 221 on both sides of the outer peripheral surface. A rotating block 52 is also provided at the end of the rotating shaft 2 5, and the rotating shaft 2 5 can be rotated by rotating the rotating block 52.

[0040] The scraper 3 and the connecting arm 41 are connected by a connecting rod 42. At the same time, a rotating groove 31 is opened in the middle of the scraper 3 to enable the connecting rod 42 to rotate. A positioning column 32 is extended downward from the top of the rotating groove 31, and one end of the positioning column 32 passes through the connecting rod 42.

[0041] A docking hole 211 is provided inwardly at one end of the docking rod 21, and a docking block 34 is provided extending from the opening corresponding to the docking hole 211 on one side of the surface of the scraper 3. Therefore, when the scraper 3 needs to be disassembled and replaced, the rotating shaft 2 5 can be rotated. When the rotating shaft 2 5 rotates, the threaded threads 51 provided on both sides are threadedly connected with the threaded sleeve 4, so that the two opposite threaded sleeves 4 can move toward the center at the same time, and then the scraper 3 can be pushed outward through the connecting rod 42, and then the docking block 34 can be separated from the docking rod 21, and then the scraper 3 can be pulled upward to be disassembled, and then the disassembly is convenient.

[0042] like Figure 4-Figure 9As shown, a piston block 6 capable of scraping off the oil stains at the opening of the docking hole 211 is provided inside the docking hole 211, and a pull rod 61 is provided at the bottom of the piston block 6 extending toward the bottom of the scraper 3, and a positioning column 2 33 is provided at the bottom of the scraper 3 opposite to the upper part of the pull rod 61. Therefore, when the scraper 3 needs to be disassembled, the scraper 3 can be pushed outwards by the connecting rod 42, and as the scraper 3 moves through the positioning column 2 33 and the pull rod 61, the piston block 6 can be continuously moved toward the opening of the docking hole 211 during movement, and then when the piston block 6 moves, the oil stains at the opening of the docking hole 211 can be cleaned. And after the docking block 34 is moved out of the docking hole 211, the gravity of the scraper 3 can be supported by the pull rod 61 and the connecting rod 42, so that the scraper 3 can be taken down upwards. At the same time, when installing, the corresponding positioning column 1 32 and positioning column 2 33 are used to prevent deviation during installation.

[0043] The working principle of a waste oil dehydration and separation device that is easy to disassemble: when the scraper 3 needs to be disassembled and replaced, the rotating shaft 25 can be rotated. When the rotating shaft 25 rotates, the threaded threads 51 provided on both sides are threadedly connected to the threaded sleeve 4, so that the two relative threaded sleeves 4 can move toward the center at the same time, and then the scraper 3 can be pushed outward through the connecting rod 42, so that the docking block 34 can be separated from the docking rod 21, and then the scraper 3 is pulled upward to disassemble the scraper 3, which is convenient for disassembly. At the same time, as the scraper 3 moves, the positioning column 233 and the pull rod 61 can be used to make the piston block 6 continuously move toward the opening of the docking hole 211 during movement, and then when the piston block 6 moves, the oil stains at the opening of the docking hole 211 can be cleaned. After the docking block 34 is moved out from the docking hole 211, the gravity of the scraper 3 can be supported by the pull rod 61 and the connecting rod 42, so that the scraper 3 can be taken down upwards. At the same time, during installation, the corresponding positioning column 1 32 and the positioning column 2 33 are used to prevent deviation in installation.
