[0031] like Figure 5-10 As shown, this example can achieve the effect that the mineral oil is filtered multiple times by multiple cotton plates 404 after passing through multiple cotton plates 404 .

[0032] Since the transformer oil processing device includes a flat box 101, the left and right sides of the flat box 101 are open, a vertically arranged vertical plate 301 is welded in the middle of the flat box 101, and a lifting member 302 is vertically slidably connected to the vertical plate 301, and the left and right ends of the lifting member 302 are hinged with inclined plates 401, and the bottoms of the two inclined plates 401 are both placed on the upper side of the flat box 101, and each inclined plate 401 is provided with a plurality of cotton plates 404 from top to bottom, and the lifting member 302 can slide vertically on the vertical plate 301 to adjust the inclination of the two inclined plates 401. The greater the inclination of the two inclined plates 401, the easier it is for the mineral oil to flow downward. After the two inclined plates 401 are adjusted to a suitable inclination, the mineral oil is dripped from the upper side of the two inclined plates 401, and then the mineral oil flows downward along the two inclined plates 401. After passing through the plurality of cotton plates 404, the mineral oil is filtered multiple times by the plurality of cotton plates 404, and the particulate impurities contained in the mineral oil are fully removed.

[0033] like Figure 9-10 As shown, this example can achieve the effect of removing and replacing multiple cotton panels 404.

[0034] Since two threaded columns 403 are welded on the upper part of the inclined plate 401, the disassembly plate 402 is inserted into the two threaded columns 403, and nuts are threadedly connected on the threaded columns 403. Multiple cotton boards 404 are bonded to the disassembly plate 402 from top to bottom, and the disassembly plate 402 can be disassembled from the threaded columns 403. The nuts block the disassembly plate 402 to prevent the disassembly plate 402 from detaching from the threaded columns 403. After the disassembly plate 402 is removed, the multiple cotton boards 404 can be removed and replaced.

[0035] like Figure 5-8 As shown, this example can achieve the effect of driving the lifting member 302 to move up and down on the vertical plate 301.

[0036] Since the rear side of the flat box 101 is connected with a telescopic rod 104 by screws, the movable end of the telescopic rod 104 is connected to the rear of the lifting member 302 by screws. The lifting member 302 can be driven to rise and fall on the vertical plate 301 by the telescopic rod 104.

[0037] like Figure 7-8 As shown, this example can achieve the effect of conveniently removing impurities in mineral oil.

[0038] Since the front and rear ends of the upper side of the vertical plate 301 are connected with connecting strips 305 by screws, strip boxes 303 are welded between the left ends and the right ends of the two connecting strips 305, and an oil inlet pipe 304 is arranged on the upper part of the strip box 303, and a plurality of circular holes 306 are arranged on the lower side of the strip box 303 from front to back, and oil can be supplied into the strip box 303 through the oil inlet pipe 304, and then the mineral oil drips out from the plurality of circular holes 306, so that the mineral oil drips evenly from the plurality of circular holes 306 onto the upper part of the corresponding inclined plate 401, so as to facilitate the removal of impurities in the mineral oil.

[0039] like Figure 5-6 As shown, this example can achieve the effect of making the cotton tube 203 easier to absorb impurities.

[0041] like Figure 5-6 As shown, this example can achieve the effect of fully adsorbing the mineral oil on the flat box 101.

[0042] Since the front and rear ends of the lower side of the flat box 101 are connected to the support frame 102 by screws, a convex plate 106 is welded on the support frame 102 located on the rear side, the middle part of the cross column 105 is welded to the convex plate 106, and the left and right ends of the cross column 105 are slidably connected to the motor frame 205, and the two motors 204 are respectively connected to the upper parts of the two motor frames 205 by screws, and each motor frame 205 is connected to a telescopic rod 206 by screws, and the movable end of the telescopic rod 206 is connected to the convex plate 106 by screws. The motor frame 205 can be driven to move left and right on the cross column 105 through the telescopic rod 206, and then the motor 1 204, the cylinder 201 and the cotton cylinder 203 can be driven to move left and right, so that the cotton cylinder 203 rotates and moves left and right on the flat box 101, and the mineral oil on the flat box 101 is fully adsorbed.

[0043] like Figure 5-6 As shown in FIG. 11 , this example can achieve the effect that the mineral oil after impurities are removed is finally collected in the bottom box 501 .

[0044] Since the lower ends of the two support frames 102 are connected to the front and rear ends of the middle of the bottom box 501 by screws, the left and right sides of the bottom box 501 are provided with inclined surfaces 509, and the left and right ends of the flat box 101 are respectively located above the two inclined surfaces 509, and the front side of the bottom box 501 is provided with an outflow pipe 502, and a valve is provided on the outflow pipe 502, and the mineral oil on the flat box 101 will flow down from the left and right ends of the flat box 101, and the two inclined surfaces 509 respectively receive the mineral oil flowing down from the left and right ends of the flat box 101, and the mineral oil after removing impurities is finally collected in the bottom box 501. The outflow pipe 502 is provided with a valve, and the mineral oil in the bottom box 501 can be discharged by opening the valve.

[0045] like Fig.11 As shown, this example can achieve the effect of mixing the mineral oil and other additives in a large area on the upper side of the bottom box 501.

[0046] Since the transformer oil processing device also includes a cross frame 507, the two ends of the cross frame 507 are respectively connected to the two ends of the bottom box 501 by screws, the slider 505 is connected to the cross frame 507 in a transverse sliding manner, one end of the cross frame 507 is connected to a telescopic rod 3 508 by screws, the movable end of the telescopic rod 3 508 is connected to the slider 505 by screws, the slider 505 is connected to a motor 2 506 by screws, the output shaft of the motor 2 506 is connected to a turntable 503, a plurality of arc-shaped pieces 504 are welded in a ring shape on the turntable 503, and the plurality of arc-shaped pieces 504 are all in contact with the upper side of the bottom box 501. Other additives are added to the mineral oil in the bottom box 501, and then the turntable 503 is driven to rotate by the motor 2 506. When the turntable 503 rotates, it drives multiple arc-shaped plates 504 to rotate. The mineral oil and other additives are mixed through the rotation of the multiple arc-shaped plates 504. Then, the slider 505 is driven by the telescopic rod 3 508 to move left and right on the horizontal frame 507 to mix the mineral oil and other additives in a large area on the upper side of the bottom box 501.
