A heavy oil adsorption plate is arranged in the second treatment tank.

[0004] Although existing wastewater treatment oil removal and skimming devices have completed the oil removal work, the oil cannot be quickly collected and cleaned up during the oil removal process, causing the oil to remain attached to the components of the oil removal equipment, which in turn leads to a gradual decrease in the oil removal effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the oil stains cannot be quickly collected and cleaned during the oil removal process, resulting in the oil stains always adhering to the parts of the oil removal equipment and thus causing the oil removal effect to gradually decrease. Therefore, this invention proposes an oil removal and slag skimming device for sewage treatment plants.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil removal and skimming device for a sewage treatment plant, comprising a treatment tank, a water conveying mechanism at the top of the treatment tank, a filtration mechanism at one end of the inner side of the treatment tank, a residue collection mechanism at one end of the treatment tank, an oil removal mechanism at the top of the treatment tank, and an oil collection mechanism at the other end of the treatment tank. The treatment tank includes a tank body, the water conveying mechanism includes a sewage inlet pipe positioned above the tank body, and the filtration mechanism includes a filter frame. The filter frame is positioned directly below the sewage inlet pipe. The oil removal mechanism includes an oil removal frame, on which lifting cylinders are symmetrically mounted. A connecting frame is connected to the bottom of each lifting cylinder. An oil removal roller is movably mounted on the inner side of the connecting frame. An oil removal motor is mounted at one end of the connecting frame, and the output end of the oil removal motor is connected to one end of the oil removal roller. Guide rails are movably connected to both ends of the oil removal frame. A lead screw is mounted on the inner side of each guide rail, and the outer wall of the lead screw is threaded to one end of the oil removal frame. A translation motor is mounted at one end of the guide rail.

[0007] Preferably, a connecting block is fixedly connected to one side of the filter frame, a rotating shaft is installed through the inner side of the connecting block, and a flip motor is provided at one end of the rotating shaft.

[0008] Preferably, the residue collection mechanism includes a residue collection box, and a steering shaft is rotatably mounted at the four corners of the bottom of the residue collection box.

[0009] Preferably, a bogie is connected to the bottom of the steering shaft, and a movable wheel is movably mounted on the inner side of the bogie.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the oil removal frame provides installation support for the lifting cylinder. The lifting cylinder lifting control connecting frame realizes the lifting adjustment function. The connecting frame is connected to the oil removal roller, and one end of the connecting frame is equipped with an oil removal motor to drive the oil removal roller to rotate. The oil removal frame is slidably installed at both ends through guide rails, and cooperates with the translation motor to drive the screw to rotate, thereby driving the oil removal frame and the oil removal roller to move.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0028] like Figures 1-6As shown, this utility model provides a technical solution: an oil removal and slag skimming device for a sewage treatment plant, including a treatment tank 1, a water conveying mechanism 2 at the top of the treatment tank 1, a filtration mechanism 3 at one end of the inner side of the treatment tank 1, a residue collection mechanism 4 at one end of the treatment tank 1, an oil removal mechanism 5 at the top of the treatment tank 1, and an oil collection mechanism 6 at the other end of the treatment tank 1.

The oil collection mechanism 6 includes an oil collection tank 601. The oil collection tank 601... A side support rod 602 is fixedly installed on the inner side, and an oil scraper 603 is fixedly connected to one end of the side support rod 602. Several through holes 604 are evenly distributed on the oil scraper 603. An oil drain port 605 is opened at the center of the bottom of the oil collection tank 601.

The oil removal frame 501 is slidably mounted at both ends via guide rails 506, and a translation motor 508 drives a lead screw 507 to rotate, thereby moving the oil removal frame 501 and the oil removal roller 504. This facilitates moving the oil removal roller 504 to the inner side of the tank 101, bringing it closer to the floating oil in the wastewater. The oil removal motor 505 drives the oil removal roller 504 to rotate, thus adsorbing the oil onto the roller 504, providing efficient oil removal and cleaning. After the oil removal roller 504 has adsorbed a certain amount of oil, the translation motor 508 controls the lead screw 507 to rotate, thereby moving the oil removal roller 504 closer to the inner side of the tank. Near the scraper 603, the oil removal motor 505 drives the oil removal roller 504 to rotate, which, in conjunction with the connecting frame 503, scrapes off the oil on the oil removal roller 504, achieving high-efficiency oil removal and reducing oil adhesion, thereby improving the subsequent oil removal effect. The filter frame 301 is connected via the connecting block 303, and the rotating shaft 304 is connected to the tilting motor 305 for further rotation adjustment. This allows the tilting motor 305 to drive the connecting block 303 and the filter frame 301 to tilt, facilitating the automatic and efficient emptying of residue from the filter frame 301 into the residue collection box 401 when it is full. During the process, the guide plate 306 provides guiding and conveying to ensure the accuracy of dumping. The residue is collected centrally by the residue collection box 401, and the bottom of the residue collection box 401 is connected and supported by the steering shaft 402 and the bogie 403, and can be moved, thus facilitating efficient transfer after collection. The inner side support rod 602 of the oil collection box 601 can support the oil scraper 603, and the oil scraper 603 has several through holes 604, thus facilitating efficient oil scraping function to ensure the oil removal effect in the later stage.
