DETAILED DESCRIPTION

[0021] Reference Figures 1 to 4 As shown, the utility model provides a cutting fluid filter, comprising: a filter body 1 and a cleaning assembly 2, a filter element assembly 11 is arranged inside the filter body 1, and the filter element assembly 11 comprises an outer metal filter 111 and an inner microporous folded filter element 112, and an underwater electromagnet 113 is connected to the inner wall of the metal filter 111, the cleaning assembly 2 is arranged at the upper and lower ends of the filter body 1, and the cleaning assembly 2 comprises a sealing box 21, and a motor 22 and a reel 23 are arranged inside the sealing box 21, and a cleaning ring 25 is connected to the outer side of the reel 23 through a wire rope 24, and the cleaning ring 25 is slidably sleeved on the outer side of the metal filter 111.

[0022] In this embodiment, the filter body 1 and the cleaning assembly 2 constitute the overall structure of the cutting fluid filter involved in this application.

[0023] Specifically, the installation position of the sealing box 21 is staggered with the positions of the liquid inlet pipe 15 and the liquid outlet pipe 17 set below, so that the sealing box 21 is slightly tilted relative to the top center of the filter body 1, so the section of the wire rope 24 located in the sealing box 21 is in an inclined state.

[0024] Specifically, the outer diameter of the wire rope 24 is relatively thin, and two wire ropes are provided on the upper and lower sides of the cleaning ring 25 to connect with it, so that it has good stability when pulled up and down. At the same time, when the wire rope 24 passes through the outer shell of the filter body 1, the part connected with it is set as a seal embedded in the outer shell, so that when the wire rope 24 slides through the seal, it will not cause the seepage of the cutting fluid.

[0025] like Figure 1 and Figure 3 As shown, the filter body 1 includes an outer shell and an inner cavity, and a liquid inlet pipe 15 is connected to the upper end of the outer shell, and a liquid pump 16 is connected to the outer end of the liquid inlet pipe 15, and a liquid outlet pipe 17 is connected to the outer end of the outer shell of the filter body 1, and a filter box 18 is connected to the outer end of the liquid outlet pipe 17, and the liquid outlet pipe 17 is directly inserted into the outer shell and connected to the outlet opened at the lower end of the filter element assembly 11, a mobile power supply 13 is installed on the outer shell wall of the filter body 1, and the mobile power supply 13 is electrically connected to the underwater electromagnet 113 through a controller, and a discharge hole 14 is opened at the bottom of the outer shell of the filter body 1, and a solenoid valve is provided in the discharge hole 14, the microporous folded filter element 112 is set as a cylindrical structure, and the central cavity of the cylinder is set as a through hole 114, and the underwater electromagnet 113 is vertically inserted in the folded material layer of the microporous folded filter element 112.

[0026] Specifically, the filter box 18 has the same structure as the related components involved in the prior art reference document, and the cutting fluid coming out of the filter box 18 can be used directly.

[0027] Specifically, the pore size of the metal filter 111 is larger than the overall density of the wire brush 252 mentioned below, so that when the wire brush 252 contacts the metal filter 111, part of the brush can pass through the mesh to reach the outer wall of the microporous folded filter element 112.

[0028] Through the above technical solution, when the wire brush 252 moves back and forth up and down on the surface of the metal filter 111 and the microporous folded filter element 112, the original liquid containing cutting fluid enters the inner through hole 114 from the outside of the filter element assembly 11, so most of the impurities and metal particles are attached to the surface of the filter element assembly 11, thereby achieving a mobile cleaning effect.

[0029] like Figure 1 and Figure 4 As shown, the sealing box 21 is respectively fixed at the upper and lower ends of the filter body 1, and the wire rope 24 is respectively connected to the upper and lower sides of the cleaning ring 25, and the wire rope 24 slides through the outer shell of the filter body 1, the cleaning ring 25 includes a ring body 251, and a wire brush 252 is provided on the inner wall of the central ring hole of the ring body 251, and guide holes 253 are symmetrically opened on the outer side of the ring hole, and two guide rods 12 parallel to the filter element assembly 11 are symmetrically provided on the outer side, and the guide rods 12 slide through the guide holes 253.

[0030] Through the above technical solution, the guide hole 253 and the guide rod 12 are set to maintain the stability of the up and down reciprocating movement of the cleaning ring 25, and when cleaning, the liquid pump 16 can be connected to a clean water source so that the cleaned impurities can be flushed through the liquid inlet pipe 15, thereby accelerating the efficiency and thoroughness of discharge from the discharge hole 14.

[0031] It should be noted that when the filter element assembly 11 is cleaned many times inside the filter body 1, it is still necessary to disassemble and replace the filter element assembly 11 to ensure the filtering effect.

[0032] When in use, the cutting fluid introduced into the filter body from the liquid inlet pipe is initially filtered, and then finely filtered through the microporous folded filter element. In the process, the metal filter is synchronously magnetized by energizing the underwater electromagnet, which facilitates the adsorption and filtration of metal particles in the cutting fluid. When cleaning, the underwater electromagnet is first powered off, and then the motors located on the upper and lower sides of the filter body are started successively. The motor drives the reel to rotate, and then the cleaning ring is driven up and down by the wire rope. Then, the wire brush provided on the inner side of the cleaning ring is used to remove the metal particles adsorbed on the metal filter and the impurities on the surface of the microporous folded filter element, and then they are discharged by opening the discharge hole on the lower side.

[0033] The cutting fluid filter of the utility model can effectively solve the problems that the existing cutting fluid filters have poor filtering effect on metal particles and the cleaning process of the filter element is relatively troublesome. It achieves the effect of adsorbing and filtering metal particles on the basis of the existing cutting fluid filter technology, thereby improving the comprehensiveness of the filtration, and at the same time facilitates the cleaning of the filter element directly inside the filter, thereby improving the convenience of use.
