[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a cutting fluid filtration device for plunger milling, referring to... Figure 1-3 The system includes a collection tank 1, a storage tank 2, and a filtration mechanism. The filtration mechanism is connected between the collection tank 1 and the storage tank 2. A filter screen (not shown in the figure) is installed in the collection tank 1. The filtration mechanism includes a frame and a pressure assembly 3 and an iron removal assembly 4 mounted on the frame. The pressure assembly 3 is connected to the collection tank 1 and is used to deliver the cutting fluid into the iron removal assembly 4. The storage tank 2 is connected to the iron removal assembly 4. The iron removal assembly 4 includes a tank body 41, a top cover 42, a magnetic rod 43, a lifting frame 44, a lifting cylinder 45, a waste removal cylinder 46, and a scraper 47. The body 41 is fixed on the frame. A connecting pipe is connected between adjacent tanks 41. The adjacent connecting pipes are arranged at vertical intervals. The lifting cylinder 45 is vertically fixed on the frame and is used to drive the lifting frame 44 to move up and down. The lifting frame 44 is fixed with a top cover 42 corresponding to the position of the tank 41. The magnetic rod 43 is fixed at the bottom of the top cover 42. The waste removal cylinder 46 is fixed on the lifting frame 44. The scraper 47 is matched and sleeved on the surface of the magnetic rod 43. The waste removal cylinder 46 is used to drive the scraper 47 to move up and down. Sealing gaskets are fixed on both sides of the scraper 47 corresponding to the positions of the top cover 42 and the tank 41, respectively.

[0021] Reference Figure 1 and Figure 3The pressure assembly 3 includes a vertical cylinder 31, a vertical cylinder 32, and a piston 33. The middle of one side of the vertical cylinder 31 is connected to the liquid collection tank 1, and the height of the vertical cylinder 31 is higher than the height of the liquid collection tank 1. One side of the bottom of the vertical cylinder 31 is connected to the bottom of the tank body 41, and a one-way valve is installed in the pipeline connecting the vertical cylinder 31 and the tank body 41. The vertical cylinder 32 is fixed inside the vertical cylinder 31, and the piston 33 is fixed to the end of the piston rod of the vertical cylinder 32. The piston 33 includes an annular body 331, with symmetrical openings on both sides of the annular body 331. There is a through groove 332, and a sealing plate 333 is provided at the bottom of the through groove 332. One side of the sealing plate 333 is hinged to the annular body 331. When the piston 33 moves downward, the sealing plate 333 can be flipped up and attached to the annular body 331 under the action of water resistance. When the piston 33 moves upward, the liquid can flow through the through groove 332. An inspection port is provided on the side of the bottom end of the vertical cylinder 31, and a filter plate is provided at the position where the vertical cylinder 31 is connected to the tank 41. The filter plate can prevent large iron filings from entering the tank 41.

[0022] Reference Figure 2 The bottom of the frame is provided with a waste collection trough 5, and a guide plate 6 is provided on the surface of the waste collection trough 5. The guide plate 6 is slidably installed in the waste collection trough 5, and a thrust cylinder 7 for driving the guide plate 6 is also fixed in the waste collection trough 5.

[0023] With the waste collection trough 5 and the guide plate 6 installed, scrap iron filings can be directly scraped into the waste collection trough 5 in conjunction with the scraper 47, thus achieving automated waste removal.

[0024] The implementation principle of a cutting fluid filtration device for plunger milling in this application embodiment is as follows:

[0025] The cutting fluid carrying the waste chips flows into the collection tank 1, where large-volume iron chips are intercepted by the filter screen. The cutting fluid carrying the waste chips enters the vertical cylinder 31. The vertical cylinder 32 pushes the piston 33 downward. The sealing plate 333 in the piston 33 is laid flat at the bottom of the channel 332 under the action of resistance, so that the cutting fluid in the vertical cylinder 31 can be squeezed into the iron removal component 4. After flowing through several tanks 41, the cutting fluid enters the storage tank 2. During this process, the cutting fluid in the tank 41 can fully contact the magnetic rod 43. The magnetic rod 43 adsorbs the waste chips. After multiple layers of adsorption, the cutting fluid entering the storage tank 2 is relatively clean.

[0026] After the magnetic rod 43 has been adsorbing for a period of time, the pressure component 3 stops working, the lifting cylinder 45 drives the lifting frame 44 to rise, thereby lifting the magnetic rod 43. The thrust cylinder 7 pushes the guide plate 6 to move to the bottom of the magnetic rod 43. The waste removal cylinder 46 works to drive the scraper 47 to move downward, thereby scraping off the waste on the magnetic rod 43. The waste accumulates in the waste collection tank 5 on the guide plate 6.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
