The device includes a first chamber and a second chamber. A cover plate is detachably connected to the top surface of the second chamber. A partition plate is fixed inside the second chamber and on its bottom wall. The front chamber is connected to the first chamber. A surrounding plate is fixed to the rear end face of the partition plate. A cavity is formed between the surrounding plate, the partition plate, and the bottom wall of the second chamber. A first U-shaped groove communicating with the cavity is formed on the end face of the partition plate, and a second U-shaped groove communicating with the cavity is formed on the end face of the surrounding plate. A shell is fixed to the top surface of the cover plate. The inner cavity of the shell is connected to the cavity. A through groove communicating with the inner cavity is formed on the right side wall of the shell. A channel steel inclined to the right and downward is welded into the through groove. The device has a compact structure, greatly improves the oil separation efficiency in the coolant, and is easy to operate. This application provides an oil-water separation device with a different structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a grinding fluid oil-water separation device in response to the above-mentioned technical deficiencies.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grinding fluid oil-water separation device, including a box with an open upper part, a motor is arranged above the box, a rotating wheel is arranged on the rotating shaft of the motor, an oil-adhesive strip is hung on the rotating wheel, the lower end of the oil-adhesive strip hangs into the box, and also includes at least one oil collection box located above the box, the upper part of the oil collection box is open and a scraper is arranged on one side of the opening, the scraper gradually tilts upward from the direction of approaching to moving away from the oil collection box, and the upper end of the scraper contacts the oil-adhesive strip.

[0006] To further optimize this technical solution, a top plate is also provided above the box body, and a pressing component is slidably connected to the top plate. A pressure roller is rotatably connected to the lower end of the pressing component, and the pressure roller presses the upper part of the oil-adhesive strip onto the rotating wheel.

[0007] To further optimize this technical solution, both ends of the pressure roller are provided with retaining edges, and the distance between the two retaining edges is greater than the length of the roller and the width of the oil-adhesive strip.

[0008] To further optimize this technical solution, a first groove is provided on the pressure roller, and a second groove is provided on the rotating wheel.

[0009] To further optimize this technical solution, an oil outlet pipe is provided on one side of the oil collection box.

[0010] To further optimize this technical solution, the number of oil accumulation boxes is two, and they are located on the inner and outer sides of the oil-adhesive strip, respectively.

[0011] Compared with the prior art, the present invention has the following advantages: an oil-adhesive strip is hung on a wheel set on the motor shaft, and the lower end of the oil-adhesive strip hangs into the grinding fluid inside the housing. The rotation of the motor can drive the oil-adhesive strip to rotate, and the scraper scrapes off the oil on the oil-adhesive strip, thereby separating the oil from the grinding fluid to prevent excessive oil in the grinding fluid. It has a reliable oil removal effect, and the structure is relatively simple and the cost is low. Attached Figure Description

[0014] In the diagram: 1. Box body; 2. Oil-adhesive strip; 3. Oil collection box; 31. Scraper; 4. Motor; 5. Top plate; 6. Pressing assembly; 61. Pressure roller; 611. First groove; 612. Side guard; 7. Rotary wheel; 71. Second groove. Detailed Implementation

[0015] To make the structure and function of this utility model clearer, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] Detailed implementation method: combined with Figure 1-2As shown, a grinding fluid oil-water separation device includes a housing 1 with an open top. A motor 4 is mounted above the housing 1, and a rotating wheel 7 is mounted on the shaft of the motor 4. The axis of the rotating wheel 7 preferably extends horizontally. An oil-adhesive strip 2 is hung on the rotating wheel 7, and the oil-adhesive strip 2 is looped end to end, resembling a belt. The oil-adhesive strip 2 is made of an oleophilic and hydrophobic material and is relatively thin. The lower end of the oil-adhesive strip 2 hangs into the housing 1. The device also includes at least one oil collection box 3 located above the housing 1. The upper part of the oil collection box 3 is open, and a scraper 31 is mounted on one side of the opening. The scraper 31 gradually tilts upward from near to far from the oil collection box 3, and the upper end of the scraper 31 contacts the oil-adhesive strip 2. In use, combined with... Figure 1 As shown, the grinding fluid is contained in the housing 1. The lower end of the oil-adhesive belt 2 hangs into the grinding fluid. Oil can adhere to the surface of the oil-adhesive belt 2. The motor 4 drives the rotary wheel 7 to rotate clockwise, causing the oil-adhesive belt 2 to rotate clockwise as well. The oil adhering to one side of the oil-adhesive belt 2 is scraped off by the scraper 31 and flows into the oil collection box 3, thereby reducing the amount of oil in the grinding fluid. When grinding the roll, the grinding fluid containing oil generated during grinding is continuously added to the housing 1 from the upper right side. The grinding fluid in the housing 1 flows out from the outlet pipe on one side of the housing 1. The motor 4 runs continuously, constantly separating the oil from the grinding fluid, so that the oil content in the grinding fluid is low and does not increase.

[0017] Furthermore, a top plate 5 is provided above the box body 1, and a pressing component 6 is slidably connected to the top plate 5. A pressure roller 61 is rotatably connected to the lower end of the pressing component 6. The pressure roller 61 presses the upper part of the oil-adhesive tape 2 onto the rotating wheel 7, making it less likely for the oil-adhesive tape 2 to slip relative to the rotating wheel 7.

[0018] Furthermore, both ends of the pressure roller 61 are provided with retaining edges 612. The distance between the two retaining edges 612 is greater than the length of the roller 7 and the width of the oil-adhesive strip 2, so that the oil-adhesive strip 2 will not fall off the roller 7.

[0019] Furthermore, the pressure roller 61 is provided with a first groove 611, and the rotating roller 7 is provided with a second groove 71. The width of the first groove 611 and the second groove 71 is larger and smaller than the width of the oil-adhesive strip 2. The presence of these two grooves makes it easier for the oil on the oil-adhesive strip 2 to pass between the rotating roller 7 and the pressure roller 61.

[0020] Furthermore, an oil outlet pipe is provided on one side of the oil collection box 3, and the oil outlet pipe is connected to the oil collection tank through a flexible hose, so that the oil collection box 3 does not need to be cleaned regularly.

[0021] Furthermore, there are two oil collection boxes 3, which are located on the inner and outer sides of the oil-adhesive strip 2, respectively, which improves the separation efficiency.

[0022] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
