Specific implementation manner

[0017] Refer to Figures 1 to 4 As shown in the figure, the present utility model provides a cutting fluid filtration and oil removal device, including: a filtration tank 1, the bottom of the inner cavity of the filtration tank 1 is fixedly connected with an electric rod 2, and the filtration component 3 is slidably connected inside the inner cavity of the filtration tank 1 through the electric rod 2, and the upper surface of the filtration tank 1 is fixedly connected with an oil removal tank 5 through a support column 4, and the filtration tank 1 and the oil removal tank 5 are communicated through a connecting pipe. At the same time, the upper ends of the side surfaces of the inner cavity of the oil removal tank 5 are symmetrically connected with liquid level sensors 6, and the upper surface of the oil removal tank 5 is fixedly connected with a protective shell 11. A through hole is correspondingly opened at a position on the upper surface of the oil removal tank 5 located inside the protective shell 11, and the top of the protective shell 11 is fixedly connected with a servo electric cylinder 12. The telescopic rod of the servo electric cylinder 12 passes through the through hole and is fixedly connected to the outer shell of the main motor 10, and the output shaft of the main motor 10 is fixedly connected to the rotating plate 9. The rotating plate 9 is movably connected to the oil absorption cotton 7 through the fixed plate 8.

[0018] In this embodiment, the cutting fluid to be processed is injected into the oil removal tank 5 from the feeding port. When the liquid level in the oil removal tank 5 submerges the liquid level sensor 6, the liquid level sensor 6 will send a signal to the electrically connected PLC component, and the PLC component will light up the electrically connected warning light, facilitating the worker to stop injecting the cutting fluid. After closing the feeding port, the switch of the servo cylinder 12 is activated. The telescopic rod of the servo cylinder 12 pushes the main motor 10, the rotating plate 9, and the oil absorbing cotton 7 to move downward synchronously. The loading and unloading door panel of the oil removal tank 5 is made of transparent material, facilitating the worker to confirm the descending position of the oil absorbing cotton 7 in real time. When the oil absorbing cotton 7 descends to a suitable position, the switch of the main motor 10 is activated. The output shaft of the main motor 10 drives the fixedly connected rotating plate 9 to rotate, and the rotating plate 9 drives the oil absorbing cotton 7 to rotate synchronously through the fixing plate 8. Therefore, the oil absorbing cotton 7 can perform corresponding adsorption treatment on the floating oil on the surface of the cutting fluid inside the oil removal tank 5, thereby realizing rapid oil removal of the cutting fluid. Then, the solenoid valve switch of the connecting pipe is opened, and the cutting fluid in the oil removal tank 5 can be injected into the filtration tank 1 through the connecting pipe and discharged from the drain port provided at the bottom of the filtration tank 1. During the flowing process of the cutting fluid, it will sequentially pass through the upper filter plate 18 and the lower filter plate 16 in the filtration component 3, enabling the filtration component 3 to perform corresponding filtration treatment on solid impurities of different sizes carried in the cutting fluid, thereby effectively reducing the probability of the filtration component 3 being blocked by solid impurities. When the oil absorbing cotton 7 needs to be replaced, the loading and unloading door panel is opened, and the oil absorbing cotton 7 and the fixing plate 8 can be quickly pulled out. After the fitting plate of the fixing plate 8 of the new oil absorbing cotton 7 is inserted into the fitting groove opened on the rotating plate 9, the loading and unloading door panel is closed, and the loading and unloading of the rotating plate 9 and the oil absorbing cotton 7 can be completed, improving the oil removal efficiency of the device. Through the box door opened on the filtration tank 1, each component of the filtration component 3 can be sequentially disassembled, facilitating the rapid cleaning of the filtration component 3 and reducing the subsequent cleaning difficulty of the device.

[0019] As a preferred embodiment, the filtration tank 1 has a cuboid structure. The four groups of support columns 4 symmetrically connected to the upper surface of the filtration tank 1 are all cylindrical structures, and the oil removal tank 5 has a cylindrical structure. At the same time, the protective shell 11 fixedly connected to the upper surface of the oil removal tank 5 has a concave structure, and the warning light and the PLC component are respectively fixedly connected to the upper surface of the oil removal tank 5.

[0020] In this embodiment, as Figure 1 and Figure 3 , the setting of the support columns 4 can assist in enhancing the stability of the connection between the filtration tank 1 and the oil removal tank 5, and ensure that the solenoid valve can be smoothly installed on the connecting pipe between the oil removal tank 5 and the filtration tank 1, thereby facilitating the worker to control the flowing time of the cutting fluid inside the oil removal tank 5.

[0022] In this embodiment, as shown in Figure 1 and Figure 4 , the arrangement of the moving frame 14 and the fixing frame 13 enables the filtering component 3 to be pushed by the electric rod 2, thus facilitating the loading and unloading of the filtering component 3. The electric rod 2 adopts a waterproof model. At the same time, the outer side surface of the moving frame 14 is adapted to the inner cavity size of the filtering box 1, which can assist in enhancing the stability of the moving frame 14 during movement.

[0023] As a preferred embodiment, the four groups of positioning rods 15 symmetrically connected to the upper surface of the moving frame 14 are all cylindrical structures. The upper ends of the positioning rods 15 are all provided with threaded structures. The thickness of the moving frame 14 is greater than that of the fixing frame 13.

Moreover, the positioning rods 15 can further enhance the fastening of the connection between the components within the filtering component 3 through the screwed nuts.

[0025] As a preferred embodiment, both the lower filtering plate 16 and the upper filtering plate 18 have a square structure.

The pressure-bearing ring 17 has a rectangular structure with an opening in the middle. At the same time, the groove in the middle of the upper surface of the upper filtering plate 18 has a spherical structure.

[0026] In this embodiment, as shown in Figure 1 and Figure 4 , the aperture of the filtering holes of the upper filtering plate 18 is larger than that of the lower filtering plate 16. Therefore, solid impurities of different sizes in the cutting fluid can be filtered by the upper filtering plate 18 and the lower filtering plate 16 respectively, effectively reducing the probability of the upper filtering plate 18 and the lower filtering plate 16 being blocked. At the same time, the pressure-bearing ring 17 is made of soft rubber material, which can effectively enhance the sealing effect of the contact surface between the lower filtering plate 16 and the upper filtering plate 18.

At the same time, the cross-section formed by combining the rotating plate 9 and the fitting groove is a concave-shaped structure.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the arc surfaces at both ends of the rotating plate 9 are mutually attached to the arc surfaces of the inner cavity of the oil removal tank 5, thereby effectively enhancing the stability of the rotating plate 9 during rotation and ensuring that the oil-absorbing cotton 7 can stably adsorb the floating oil in the oil removal tank 5.

[0029] As a preferred embodiment, the fixing plate 8 has a strip-shaped structure.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the oil-absorbing cotton 7 can be made of polyurethane sponge, thereby enhancing the adsorption effect of the oil-absorbing cotton 7 on the floating oil. At the same time, the sizes of the fixing plate 8 and the rotating plate 9 are adapted to each other. Therefore, driven by the rotating plate 9, the fixing plate 8 and the oil-absorbing cotton 7 can also rotate stably in the oil removal tank 5, ensuring that the oil-absorbing cotton 7 can smoothly adsorb the floating oil on the surface of the cutting fluid.
