It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products, or devices.

[0034] Reference Figure 1 The present embodiment provides a negative pressure centralized filtration system, which includes a filtration mechanism 1, a storage mechanism 2 and an oil removal mechanism 3. The filtrate on the filtration mechanism 1 is transferred to the storage mechanism 2, and the storage box on the storage mechanism 2 is connected to the oil removal tank 31 in the oil removal mechanism 3.

[0035] The oil removal mechanism 3 includes the above-mentioned oil removal tank 31 and an oil removal assembly 32 disposed at the opening of the oil removal tank 31. Figure 2 The oil removal assembly 32 includes a fixing member 321 disposed on one side of the oil removal tank 31 and a rotating wheel 322 disposed on the fixing member 321. In addition, the wheel surface of the rotating wheel 322 is in contact with the oil layer in the oil removal tank 31, and the axis of the rotating wheel 322 is rotationally connected to the fixing member 321. In the embodiment of the present application, the rotation of the rotating wheel 322 can bring the upper surface of the oil layer out of the oil removal tank 31; and the fixing member 321 supports the rotating wheel 322, which helps the rotating wheel 322 to play a supporting role during the oil removal process. Specifically, a motor is provided on the fixing member 321, and the output end of the motor is fixedly connected to the axis of the rotating wheel 322, thereby improving the convenience of the operation of the rotating wheel 322.

[0036] In addition, a cover 311 is provided at the box opening of the de-oiling tank 31. A connecting groove 312 for the rotating wheel 322 to pass through is provided on the cover 311. One side of the rotating wheel 322 is exposed outside the de-oiling tank 31, and the other side of the rotating wheel 322 extends into the de-oiling tank 31. Since the rotating wheel 322 will bring out the oil stains in the oil layer and generate splashes during the rotation process, and then return to the de-oiling tank 31, the design of the cover 311 is adopted to isolate the oil stains outside the de-oiling tank 31. On the other hand, the design of the cover 311 can isolate the dust outside or the odor of the oil layer in the de-oiling tank 31, thereby improving the practicality of the de-oiling tank 31. And combined with Figure 1 In addition, a cover plate 313 is provided on the oil tank 31, and the cover plate 313 is covered and fixed on the cover 311, thereby reducing the splashing caused by the oil pollution being brought out and protecting the cleanliness of the production environment.

[0037] Reference Figure 3 The cover 311 is symmetrically provided with oil scraping blades 314 on both sides of the connection groove 312. One side of the two oil scraping blades 314 abuts against the rotating wheel 322 exposed outside the oil tank 31, and the other side of the oil scraping blades 314 is fixed to the cover 311 on both sides of the connection groove 312 by screws. In addition, a guide member 315 is fixedly connected to the cover 311. The guide member 315 is a bent metal plate, which forms a guide groove for guiding oil. The guide groove can be used to drain the oil from the oil scraping blades 314. When the rotating wheel 322 brings out the oil from the oil layer during rotation, splashing will occur. The oil scraping blades 314 are used to abut against the rotating wheel 322 exposed outside the oil tank 31, so that the oil can flow out along the oil scraping blades 314. The oil drained by the oil scraping blades 314 is guided and discharged, reducing the accumulation of oil, thereby facilitating the continuous degreasing of the degreasing mechanism 3.

[0038] Reference Figure 3 Furthermore, a fixing plate 316 is provided on the cover 311 to improve the stability of the guide member 315, and the guide member 315 is also fixed to the fixing plate 316 by means of screws (not clearly shown in the view angle in the figure).

[0039] On the other hand, an oil storage tank 317 is formed on one side of the cover 311, and one end of the guide tank is connected to the oil storage tank 317, which accumulates oil pollution during the degreasing process, which is helpful for the collection and discharge of oil pollution. At the same time, an oil drain hole 318 for draining oil pollution is opened on one wall of the oil storage tank 317, and the oil drain hole 318 is connected to an external oil drain pipe, so as to facilitate the unified treatment of the collected oil pollution.
