Specific implementation

[0027] The utility model will be further explained in detail below in combination with the drawings and specific embodiments

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Indicated, the oil inlet oil-water separation device for excavator of the embodiment, including the machine shell seat 1 for being fixed on the upside of oil tank, the oil storage cavity 2 being located in the machine shell seat 1, a plurality of oil holes 3 being located in the lower side of oil storage cavity 2 and being used for connecting oil storage cavity 2 and oil tank and being arranged at interval along the circumference, a plurality of oil-water separation assemblies 4 being detachably connected with each oil hole 3 and being used for making the oil in oil storage cavity 2 pass through oil hole 3 alone, and the oil-water adding and discharging assembly 5 being located on the machine shell seat 1 and being used for adding oil or discharging water in oil storage cavity 2;

[0029] Each oil-water separation assembly 4 includes the mounting sleeve 41 being screwed with the corresponding oil hole 3, the support strip 42 being fixed on the upper side of mounting sleeve 41 and being arranged at two opposite places along the height direction, the upper fixed plate 43 being arranged above support strip 42 and being fixedly connected with the top of two side support strips 42 at the lower side, the middle limiting ring 44 being fixed between the middle segments of two side support strips 42, and the oil-water separation membrane 45 being fixed in middle limiting ring 44;

[0030] The upper end of the oil-water separation membrane 45 is fixedly connected to the lower side of the upper fixed plate 43, and the lower end is fixedly connected to the lower side of the mounting sleeve 41.

[0031] The oil-water drainage assembly 5 includes a casing cover 51 detachably arranged above the casing seat 1, an oil filling pipe 52 arranged on the side wall of the casing cover 51 and arranged in a horizontal direction, a drainage pipe 53 arranged at the lower part of the casing seat 1 and arranged in a horizontal direction, and a sealing plug 54 detachably arranged on the end of the drainage pipe 53 away from the casing seat 1.

[0032] In use, the casing seat 1 is welded to the oil tank, the oil hole 3 is arranged between the oil filling holes of the oil tank, then the casing cover 51 is mounted on the casing seat 1, the oil pipe is connected to the oil filling pipe 52, and the oil-water mixture is filled into the oil storage cavity 2 through the oil filling pipe 52. At this time, the operator rotates the opening cover 13 and pays attention to the change of the liquid level in the internal oil storage cavity 2. When the liquid level is too high, the oil pipe input is stopped. At this time, the oil in the oil-water mixture in the oil storage cavity 2 enters the oil hole 3 through the oil-water separation membrane 45, so that pure oil is added to the oil tank, and the water is separated outside the oil-water separation membrane 45 and stored in the oil storage cavity 2. When the operator observes that the liquid level in the oil storage cavity 2 no longer decreases, the oil-water mixture can be continuously added by operating the oil pipe, and the above process is repeatedly performed until the oil tank is filled, or the operator observes that the liquid level remains at a high position for a long time and no longer decreases. The sealing plug 54 is unscrewed and removed. At this time, the accumulated water in the oil storage cavity 2 is discharged outward through the drainage pipe 53 arranged, so as to empty the oil storage cavity 2, facilitate the next oil filling, reduce the load of the oil tank, and reduce the excess power consumption. After emptying, the sealing plug 54 is tightened and installed back to prevent the newly added oil-water mixture in the oil storage cavity 2 from flowing out, so that the oil added to the oil tank is relatively pure oil, and the mixed water is discharged.

[0033] As shown in Figure 1 and Figure 4 , the sealing ring 6 is arranged on the bottom of the outer wall of each mounting sleeve 41.

[0034] In use, when the mounting sleeve 41 is continuously tightened and installed into the oil hole 3 during installation of the oil-water separation assembly 4, the distance between the bottom of the outer wall of the mounting sleeve 41 and the oil storage cavity 2 is continuously reduced, so as to continuously extrude the sealing ring 6, thereby preventing the oil-water mixture from flowing into the oil tank through the distance between the lower edge of the outer wall of the mounting sleeve 41 and the oil hole 3.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the upper side of the casing base 1 is arranged with a plurality of threaded mounting holes 7 in a circumferential interval, and the casing cover 51 is arranged with threaded alignment holes 8 corresponding to each threaded mounting hole 7. Each threaded mounting hole 7 is threadedly connected with a fastening screw 9.

[0036] In use, the product is fastened and connected by aligning each threaded alignment hole 8 with the threaded mounting hole 7, installing and tightening each fastening screw 9, and fastening the casing cover 51 with the casing base 1, thereby preventing the oil storage cavity 2 from being exposed.

[0037] As shown in Figure 1 , Figure 3 and Figure 5 , the upper side of the casing base 1 is arranged with an alignment groove 10, and the bottom of the casing cover 51 is fixedly arranged with an alignment ring 11 that is slidably arranged in the alignment groove 10.

[0038] In use, the product is fastened and connected by embedding the lower alignment ring 11 in the alignment groove 10 when installing the casing cover 51, so that the threaded alignment hole 8 and the threaded mounting hole 7 are on the same circular ring, and then rotating the casing cover 51 to drive the alignment ring 11 to rotate circumferentially in the alignment groove 10, so that the operator can complete the alignment after aligning the threaded alignment hole 8 with the threaded mounting hole 7, thereby facilitating the installation operation of the operator.

[0039] As shown in Figure 1 , Figure 2 and Figure 5 , the upper side of the casing cover 51 is arranged with an observation hole 12, and the casing cover 51 is hingedly arranged with a cover 13 for shielding the observation hole 12.

[0040] In use, the operator shields or opens the observation hole 12 by rotating the cover 13.

[0041] As shown in Figure 1 , Figure 3 and Figure 4 , the edge of each upper fixed plate 43 is fixedly arranged with a plurality of anti-skid strips 14.

[0042] In use, when disassembling the oil-water separation assembly 4, the surface of the upper fixed plate 43 is often attached with an oil-water film due to the long-term oil-wrapped environment of the oil-water separation assembly 4. The anti-skid strips 14 are arranged to increase the friction when rotating and loosening, thereby facilitating the disassembly and replacement of the operator.

[0043] As shown in Figure 1 and Figure 2 , the sealing plug 54 and the drainage pipeline 53 are threadedly detachably connected.

[0044] In use, when it is necessary to discharge the water in the oil storage cavity 2, the sealing plug 53 is loosened and removed by a tool such as a handle, so that the water in the oil storage cavity 2 flows out.

[0045] The working principle of the device is:

[0046] The first step is to weld the casing base 1 on the oil tank, and place the oil hole 3 between the oil tank oil filling hole, then embed the positioning ring 11 on the lower side of the casing cover 51 into the positioning groove 10, then rotate the casing cover 51 until each threaded positioning hole 8 corresponds to each threaded mounting hole 7, at this time, each fastening screw 9 is inserted and tightened in turn at an angle, so that the casing cover 51 is fixedly connected with the casing base 1.

[0047] The second step is to connect the oil pipe with the oil filling pipe 52, and fill the oil-water mixture into the oil storage cavity 2 through the oil filling pipe 52, at this time, the operator rotates the opening cover 13 and pays attention to the change of the liquid level in the internal oil storage cavity 2, when the liquid level is too high, stop the input of the oil pipe, at this time, the oil in the oil-water mixture in the oil storage cavity 2 enters the oil hole 3 through the oil-water separation membrane 45, so that the pure oil is added into the oil tank, and the water is separated outside the oil-water separation membrane 45 and stored in the oil storage cavity 2, when the operator observes that the liquid level in the oil storage cavity 2 no longer decreases, the oil-water mixture can be continuously added and the above process is repeatedly performed.

[0048] The third step is to fill the oil tank until the liquid level is observed to be at a high position for a long time and no longer decreases, the sealing plug 54 is unscrewed and removed, at this time, the water accumulated in the oil storage cavity 2 is discharged outward through the drainage pipe 53 arranged, so as to empty the oil storage cavity 2, facilitate the next oil filling, reduce the load of the oil tank and reduce the excess power consumption, after emptying, the sealing plug 54 is screwed and installed back to prevent the newly added oil-water mixture in the oil storage cavity 2 from flowing out.

[0049] The fourth step is that after a long time of use, the surface of the oil-water separation membrane 45 is easy to be blocked and other problems, which need to be replaced, at this time, the operator unscrews each fastening screw 9 and removes the casing cover 51, then the operator holds the edge of the upper fixed plate 43 of the oil-water separation assembly 4 to be replaced, and increases the friction force between the hand and the upper fixed plate 43 through the anti-skid strip 14, then rotates the upper fixed plate 43 to separate the installation sleeve 41 at the bottom and the threaded connection with the oil hole 3, then replaces a new oil-water separation assembly 4 for subsequent use.
