[0062] It should be noted that, in order to express the figure simply, Figure 3 、 Figure 4 、 Figure 5 and Figure 6 the fixed plate, the anchor rack, the sliding shaft, the rotating shaft of the second valve control assembly are omitted, and only the third bevel gear 73 and the fourth bevel gear 74 are schematically shown, but this does not mean that the present application does not contain the above-mentioned elements.

[0063] In some more specific embodiments, as shown in Figure 5 , the cylinder cover lifting assembly comprises a first hydraulic cylinder 81, which may, for example, be a multi-section hydraulic cylinder in some more specific examples, connected with the horizontal moving assembly, and the piston rod 811 of the first hydraulic cylinder 81 is connected with the cylinder cover 3, so as to drive the cylinder cover 3 and the ion exchange resin container 2 to move in the height direction through the extension and retraction of the piston rod 811 of the first hydraulic cylinder.

[0064] In addition, as shown in Figure 5 and Figure 6As shown, the cylinder cover lifting assembly further comprises: a pair of first connecting rods 82, the lower end of each first connecting rod is hinged to the cylinder cover 3 through a corresponding first hinge shaft 821, and the upper end of each first connecting rod is connected to the horizontal moving assembly. A pair of support plates 5, each of which is provided with a vertical guide slot 51 and an inclined guide slot 52. A pair of second connecting rods 83, the lower end of each second connecting rod 83 is hinged to the cylinder cover 3 through a corresponding roller shaft, and the upper end of each second connecting rod 83 is connected to the horizontal moving assembly; a roller 831 is sleeved on each roller shaft.

[0065] As shown in Figure 4 and Figure 5 As shown, when the cylinder cover 3 and the ion exchange resin container 2 need to be taken out of the cylinder body 1, the cylinder cover 3 is first lifted, at this time the roller 831 slides upward along the vertical guide slot 51 until the roller 831 is disengaged from the vertical guide slot 51, then the cylinder cover 3 and the ion exchange resin container 2 are moved a distance in the horizontal direction by the horizontal moving assembly, then the cylinder cover 3 and the ion exchange resin container 2 are lowered, in this process, the roller 831 slides obliquely downward along the inclined guide slot 52 until it slides to the lower end of the inclined guide slot 52, at this position the ion exchange resin in the ion exchange resin container 2 can be replaced, after replacement, return along the original path, then the cylinder cover 3 and the ion exchange resin container 2 can be put back into the cylinder body.

[0066] Continuing to refer to Figure 5 In some embodiments, the horizontal moving assembly can include: a pair of horizontally extending tracks 91 fixedly arranged, a hydraulic cylinder fixing block 84 is embedded in the track 91, and the hydraulic cylinder fixing block 84 is fixedly connected with the first hydraulic cylinder 81. A pair of sliding blocks 92, the rear end of each sliding block 92 is hinged to the upper end of the corresponding second connecting rod 83 through a second hinge shaft 832, and the front end of each sliding block 92 is hingedly connected to the upper end of the corresponding first connecting rod 82 through a third hinge shaft 822. A second hydraulic cylinder 94 fixedly arranged through a hydraulic cylinder fixing plate 93, the piston rod 941 of the second hydraulic cylinder 94 is connected with the two sliding blocks 92, and the extension and retraction of the piston rod 941 of the second hydraulic cylinder drives the sliding blocks to slide along the tracks 91.

[0067] Continuing to refer to Figure 5In some preferred embodiments, the intelligent device for reducing the conductivity of cutting fluid based on ion exchange of the present application further comprises a pressure gauge 10 for detecting the pressure drop of fluid on the ion exchange resin in the ion exchange resin container, so as to determine whether the ion exchange resin needs to be regenerated or replaced. In some more specific embodiments, the pressure gauge 10 penetrates through the inside of the support rod 4 and extends into the ion exchange resin through the hole 21 on the ion exchange resin container 2. When the ion exchange resin is saturated, the resistance of water flow through the ion exchange resin will increase, so that the saturation state of the ion exchange resin can be determined by measuring the pressure drop of fluid on the ion exchange resin. If the pressure drop exceeds a certain value, it means that the ion exchange resin has been saturated and needs to be regenerated or replaced.

[0068] When the intelligent device for reducing the conductivity of cutting fluid based on ion exchange is working:

[0069] When the cutting fluid needs to be regenerated, the first ball valve 111 and the third ball valve 131 are opened by rotating the anchor rack, at this time the second ball valve 121 and the fourth ball valve 141 are closed, the cutting fluid is introduced into the ion exchange resin container 2 through the cutting fluid inlet pipe 11, and the ion exchange resin is used to regenerate the cutting fluid, and the regenerated cutting fluid flows out through the cutting fluid outlet pipe 13.

[0070] When the pressure gauge 10 detects that the ion exchange resin has been saturated, the first ball valve 111 is closed and the second ball valve 121 is opened by rotating the anchor rack, and the regeneration liquid is introduced into the ion exchange resin container 2 to regenerate the ion exchange resin.

[0071] When the ion exchange resin is used for a period of time and its performance is completely lost and cannot be regenerated, the first hydraulic cylinder 81 drives the cylinder cover 3 to vertically rise, and the second connecting rod 83 vertically rises along the vertical guide groove 51 of the support plate 5 through the roller 831. When the cylinder cover 3 and the ion exchange resin container 2 rise to the highest point, i.e. the roller 831 is detached from the vertical guide groove 51, the second hydraulic cylinder 94 drives its piston rod 941 to laterally contract, thereby driving the sliding block 92 to horizontally move along the track 91, and then driving the cylinder cover 3 and the hydraulic cylinder fixed block 84 to horizontally move a distance through the first connecting rod 82 and the second connecting rod 83. Then, the roller 831 slides obliquely downward along the oblique guide groove 52 until it slides to the lower end of the oblique guide groove 52. At this position, the ion exchange resin in the ion exchange resin container 2 can be replaced. After the replacement is completed, it returns along the original path, so that the ion exchange resin container 2 can be placed back into the cylinder body and the cylinder cover 3 is covered.
