Specific embodiments

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1 to 3As shown, a diesel supply filtering device described in an embodiment of the present invention includes a diesel generator body 1; an oil filling pipe 12 is fixedly connected to the top of the diesel generator body 1; a connecting plate 18 is fixedly connected to the side wall of the oil filling pipe 12; a connecting pipe 13 is fixedly connected to the other end of the connecting plate 18; a pair of diverter pipes 14 are fixedly connected to the side wall of the connecting pipe 13; a filter pipe 16 is detachably installed between the diverter pipe 14 and the oil filling pipe 12; a filter element 17 is detachably installed inside the filter pipe 16; valves 15 are fixedly connected to the middle of the diverter pipe 14 and the oil filling pipe 12; a plurality of valves 15 are respectively located at both ends of the filter pipe 16; when working, by rotating the plurality of valves 15 to close one filter pipe 16 and open the other filter pipe 16, the diesel supply pipeline is connected to the connecting pipe 13. The pipe fitting 13 is connected, and the supplied diesel will pass through the open filter tube 16. Inside the filter tube 16, impurities in the diesel will be filtered by the filter element 17, so that relatively pure diesel will enter the diesel generator body 1. When there are more impurities attached to the surface of the filter element 17 where diesel flows and affects the diesel supply, the pair of valves 15 corresponding to this filter tube 16 will be closed, and the other pair of valves 15 will be opened. At this time, the diesel will flow from the other filter tube 16 and be closed by the other filter tube 16. At this time, the filter tube 16 with impurities inside can be removed from between the oil filling pipe 12 and the diversion pipe 14 for cleaning or replacement. In this process, there is no need to interrupt the diesel supply to the diesel generator body 1, so that the diesel generator body 1 can continue to perform power generation operations, thereby improving the convenience of use of the device.

[0026] like Figures 1 to 4 As shown, the inner wall of the filter tube 16 is symmetrically provided with a pair of T-shaped slots 2; a connecting rod 21 is slidably connected to the middle of the T-shaped slot 2; a shaft rod 22 is rotatably connected to the middle of the connecting rod 21; a vane 23 is fixedly connected to the middle of the shaft rod 22; the end of the shaft rod 22 is fixedly connected to a first scraper 24; the first scraper 24 contacts the end face of the filter element 17; when working, the diesel entering the filter tube 16 will impact the surface of the vane 23, thereby driving the first scraper 24 to rotate, scraping off impurities attached to the surface of the filter element 17, reducing the accumulation of impurities on the surface of the filter element 17 and causing blockage, which leads to a decrease in the filtering effect of the filter element 17. When the filter element 17 needs to be cleaned or replaced, the connecting rod 21 can be slid out of the middle of the T-shaped slot 2 to remove the vane 23 and the first scraper 24, and the filter element 17 can be removed for maintenance. Through the above structure, the situation of the filter element 17 being clogged by impurities and causing a decrease in the filtering effect can be reduced.

[0027] like Figures 1 to 4As shown in the figure, a first screw sleeve 3 is rotatably connected to one end of the filter pipe 16 facing the fuel injection pipe 12; the first screw sleeve 3 is threadedly connected to the middle of the T-shaped groove 2; one end of the filter pipe 16 facing the shunt pipe 14 is slidably connected to an extension pipe 31; a second screw sleeve 32 is rotatably connected to the middle of the extension pipe 31; the second screw sleeve 32 is threadedly connected to the middle of the shunt pipe 14; during operation, when installing the filter pipe 16, align the end of the filter pipe 16 with the interface in the middle of the fuel injection pipe 12, and then rotate the first screw sleeve 3 to complete the connection between the fuel injection pipe 12 and the filter pipe 16. Then, pull the second screw sleeve 32 towards the end of the shunt pipe 14 to make the extension pipe 31 extend from the middle of the filter pipe 16. Then, rotate the second screw sleeve 32 to make the end of the extension pipe 31 closely fit the end of the shunt pipe 14, thereby completing the installation of the filter pipe 16. Through the above structure, the filter pipe 16 can be quickly and conveniently disassembled, improving the convenience of use of the device.

[0028] As Figures 1 to 3 shown in the figure, a fixing ring 4 is fixedly connected to the middle of the shaft rod 22; a second scraper 41 is fixedly connected to the side wall of the fixing ring 4; the second scraper 41 is arranged in a spiral shape, and the inner side of the second scraper 41 contacts the middle surface of the filter element 17; during operation, the second scraper 41 will rotate with the shaft rod 22. At this time, the second scraper 41 can scrape off the impurities attached to the middle of the filter element 17, thereby further reducing the situation where the filtering effect decreases due to the accumulation of impurities on the surface of the filter element 17.

[0029] As Figures 3 to 5 shown in the figure, a waste discharge pipe 5 is fixedly connected to the middle of the filter pipe 16; a plug 51 is threadedly connected to the end of the waste discharge pipe 5; during operation, before removing the filter pipe 16, the plug 51 can be rotated to remove the plug 51 from the end of the waste discharge pipe 5. The residual diesel in the filter pipe 16 will flow out from the waste discharge pipe 5, and a container can be used to catch the flowing diesel, reducing the situation where the residual diesel falls on the diesel generator body 1 when the filter pipe 16 is disassembled.

[0030] As Figure 5 shown in the figure, a fixing rod 6 is fixedly connected to the side wall of the plug 51; a plurality of brush hairs 61 are fixedly connected to the middle of the fixing rod 6; during operation, when the inside of the waste discharge pipe 5 is blocked by impurities, removing the waste discharge pipe 5 can enable the plurality of brush hairs 61 to clean the impurities inside the waste discharge pipe 5, thereby increasing the speed of discharging the residual diesel.

[0031] As Figure 4 shown in the figure, an elastic membrane sleeve 7 is fixedly connected to the side wall of the extension pipe 31; the other end of the elastic membrane sleeve 7 is fixedly connected to the end of the filter pipe 16; a rubber pad 71 is fixedly connected to the side wall of the extension pipe 31; through the above structure, the situation of diesel leakage can be reduced.

[0032] As Figure 1As shown, a diesel generator comprises the diesel generator body 1 described in any one of the above items.

[0033] During operation, by rotating multiple valves 15, one filter tube 16 is closed and the other filter tube 16 is opened, and then the diesel supply pipeline is connected to the connecting pipe 13. The supplied diesel will pass through the inside of the opened filter tube 16. Inside the filter tube 16, impurities in the diesel will be filtered by the filter element 17, so that relatively pure diesel can enter the diesel generator body 1. When there are more impurities attached to the surface of the filter element 17 where diesel flows and affects the diesel supply, the pair of valves 15 corresponding to this filter tube 16 is closed, and the other pair of valves 15 is opened. At this time, the diesel will flow from the other filter tube 16 and be closed by the other filter tube 16. At this time, the filter tube 16 with impurities inside can be removed from between the oil filling pipe 12 and the diversion pipe 14 for cleaning or replacement. The diesel entering the filter tube 16 will impact the surface of the vane 23, thereby driving the first scraper 24 to rotate, scraping off the impurities attached to the surface of the filter element 17, reducing the accumulation of impurities on the surface of the filter element 17 to cause blockage and lead to the filtration of the filter element 17 If the effect is reduced, and when the filter element 17 needs to be cleaned or replaced, the connecting rod 21 can be slid out from the middle of the T-slot 2 to remove the blade 23 and the first scraper 24, and the filter element 17 can be removed for maintenance. When installing the filter tube 16, align the end of the filter tube 16 with the interface in the middle of the oil filling pipe 12, and then rotate the first screw sleeve 3 to complete the connection between the oil filling pipe 12 and the filter tube 16, and then pull the second screw sleeve 32 toward the end of the diverter pipe 14 to make the extension pipe 31 extend from the filter. The middle part of the filter tube 16 is extended, and then the second screw sleeve 32 is rotated to make the end of the extension tube 31 fit tightly with the end of the diversion tube 14, thereby completing the installation of the filter tube 16. The second scraper 41 will rotate with the shaft 22. At this time, the second scraper 41 can scrape off the impurities attached to the middle part of the filter element 17. Before removing the filter tube 16, the plug 51 can be rotated to remove the plug 51 from the end of the exhaust pipe 5. The diesel remaining in the filter tube 16 will flow out of the exhaust pipe 5, and a container can be used to catch the flowing diesel.
