[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 4 An apparatus for recycling electrical discharge machining (EDM) waste liquid, comprising:

[0029] Reference Figure 1 、 Figure 2 As shown in the figure, the filtering mechanism 4 further comprises a first filter plate 402 and a second filter plate 403 arranged in the collecting tank 401, the filter holes of the first filter plate 402 are larger than those of the second filter plate 403, the first filter plate 402 is a positive V-shaped plate, the second filter plate 403 is an inverted V-shaped plate, first slag discharge ports 4011 are arranged on the front and rear sides of the collecting tank 401, and first collecting boxes 404 for collecting waste slag on the first filter plate 402 are arranged at the first slag discharge ports 4011; second slag discharge ports 4012 are arranged on the left and right sides of the collecting tank 401, and second collecting boxes 405 for collecting waste slag on the second filter plate 403 are arranged at the second slag discharge ports 4012; an installation frame 407 is arranged on the upper surface of the collecting tank 401, a cleaning brush 408 for cleaning the waste slag on the first filter plate 402 to the first collecting boxes 404 on both sides is slidably arranged on the installation frame 407, and the first collecting boxes 404 and the second collecting boxes 405 are slidably arranged on the collecting tank 401 through sliding blocks 406.

[0030] It should be noted that, compared with the traditional single plane filter, the two V-shaped filter plates improve the filtering area and the interception efficiency, effectively remove the solid impurities in the waste liquid, and the impurities can slide along the inclined surface of the V-shaped filter plate, which is conducive to the collection of the impurities; the impurities on the first filter plate 402 are concentrated in the middle of the filter plate, and the impurities can be cleaned into the first collecting box 404 through the sliding cleaning brush 408, and the impurities on the second filter plate 403 directly slide along the inclined surface into the second collecting box 405, thereby improving the collection efficiency of the waste slag.

[0032] It should be noted that when the centrifugal cylinder 506 rotates at high speed, the oil and water will be subjected to different centrifugal forces due to the different densities of the oil and water. The density of water is greater than that of oil, so water is more easily thrown to the outside of the centrifugal cylinder 506 into the water cylinder 501. The oil will gather in the area where the centrifugal force is relatively small because of its smaller density. At this time, the oil will gather near the hollow shaft 507, and the design of the oil holes 5071 facilitates the oil after centrifugation to pass through the oil holes 5071 into the hollow shaft 507, and when the centrifugation is finished, the oil flows into the lower end of the hollow shaft 507 and is guided out through the oil guide pipe 509.

[0033] Reference Figure 1 , Figure 3 , Figure 4 As shown, the adsorption mechanism 6 includes a water tank 601, the water tank 601 is arranged on the bottom plate 1, the lower end of the water cylinder 501 is connected with a water outlet pipe 7, the water outlet pipe 7 is used to introduce the water after centrifugation into the water tank 601; two insertion slots 6011 are arranged at intervals along the height direction of the water tank 601, a pull plate 602 is inserted in each insertion slot 6011, the pull plate 602 is provided with filter holes, and the first adsorption layer 603 and the second adsorption layer 604 for removing harmful substances in water are respectively placed in the two pull plates 602.

[0034] It should be noted that the first adsorption layer 603 and the second adsorption layer 604 can remove the harmful substances such as additive decomposition products and trace metal ions in water by using their adsorption characteristics, and finally obtain relatively pure water which can be further treated or discharged.

[0035] The working principle of the device for recycling electric spark waste liquid is as follows:

[0036] Waste liquid filtration: firstly, the generated electric spark waste liquid is poured into the collecting pool 401. The first filter plate 402 filters relatively coarse solid impurities such as large-size metal scraps and large-size carbides; the second filter plate 403 further removes small particle impurities. In this process, the operator can slide the cleaning brush 408 to regularly clean the waste residues accumulated on the first filter plate 402 to the first collecting box 404 on both sides, and the waste residues on the second filter plate 403 fall into the second collecting box 405 through the inclined surface thereof, facilitating subsequent treatment of the waste residues.

[0037] Oil-water separation stage: the filtered waste liquid flows into the centrifugal cylinder 506 through the water inlet pipe 8. The motor 505 is started to drive the centrifugal cylinder 506 to rotate at high speed. Due to the different densities of oil and water, under the action of centrifugal force, the water is thrown into the water cylinder 501, while the oil flows into the hollow shaft 507 through the oil hole 5071 on the surface of the hollow shaft 507, and the collected oil can be guided out of the collection through the oil guide pipe 509.

[0038] Adsorption purification: after oil-water separation, the water in the water cylinder 501 enters the water tank 601 through the water outlet pipe 7. The first adsorption layer 603 and the second adsorption layer 604 can effectively remove harmful substances remaining in the water, and finally obtain relatively pure water which can be further treated or discharged.
