Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides an easy abluent filter, including quick-witted case 1, strain a 2 and scavenge pipe 3, wherein be provided with apron 18 at quick-witted case 1 top, as shown in figure 1, the welding of first half has support ring 6 in quick-witted case 1, and be provided with in the opening of support ring 6 and strain a 2, and strain a 2 top overcoat welding and have the solid fixed ring 7 that is located support ring 6 top, wherein gu fixed ring 7 passes through bolt locking on support ring 6, thereby will strain a 2 unsettled fixes in quick-witted case 1 of filter, be provided with intake pipe 4 that is located the below and be located the outlet duct 5 of top respectively on quick-witted case 1 lateral wall simultaneously, and intake pipe 4 and outlet duct 5 are located the quick-witted.

The air outlet pipe 5 is connected with an air inlet pipe of the engine, when the engine works, air is continuously extracted, air enters the case 1 from the air inlet pipe 4, the entered air penetrates through the filter cartridge 2 to filter particles in the air, and the filtered air enters the engine from the air outlet pipe 5.

As shown in fig. 1, the cleaning tube 3 is vertically disposed in the chassis 1, wherein the bottom end of the cleaning tube 3 is hermetically disposed and extends into the filter cartridge 2, a V-shaped connecting tube 11 is further disposed at the top end of the cleaning tube 3, the tube bodies at two ends of the connecting tube 11 are both provided with check valves 12, and two ends of the connecting tube 11 are further respectively provided with an air duct 13 and a water guide tube 14 penetrating through a cover plate 18 at the top of the chassis 1, meanwhile, sealing rings 15 disposed at upper and lower sides of the cover plate 18 are disposed on the air duct 13 and the water guide tube 14, and are sealed by the sealing rings 15, wherein the air duct 13 and the water guide tube 14 above the cover plate 18 are provided with threads 16, and nuts 17 connected with the threads 16 are further screwed on the air duct 13 and the.

Then when the air duct 13 and the water conduit 14 are installed, the lower sealing ring 15 is sleeved on the air duct 13 and the water conduit 14, the air duct 13 and the water conduit 14 are passed through the round hole on the cover plate 18, then, a sealing ring 15 is sleeved on the air duct 13 and the water guide pipe 14 above the cover plate 18, then, the screw threads 16 of the air duct 13 and the water guide pipe 14 are screwed with nuts 17, the air duct 13 and the water guide pipe 14 are locked and fixed on a cover plate 18 by the screw threads 16 and the nuts 17, the cleaning pipe 3 is extended into the filter cartridge 2, because of the two fulcrums of the air duct 13 and the water guide duct 14, the connection bending part between the water guide duct 13, the air duct 14 and the connecting pipe 11 and the nut 17 are clamped and fixed on the cover plate 18, therefore, the stability of the connecting pipe 11 and the cleaning pipe 3 suspended in the chassis 1 is enhanced, and the air duct 13 and the water guide pipe 14 are fixed on the cover plate 18 in a screwing and locking mode through the nut 17, so that the installation and the disassembly are convenient.

And the nut 17 compresses tightly the upper sealing ring 15 on the top of the cover plate 18, and the lower sealing ring 15 is compressed on the bottom of the cover plate 18 at the connection bent part between the water guide pipe 14 and the gas guide pipe 13 and the connecting pipe 11, so that the upper and lower sealing rings 15 play a sealing role, when liquid or gas is injected into the connecting pipe 11 through the water guide pipe 14 and the gas guide pipe 13 and flows into the cleaning pipe 3, one check valve 12 can prevent the liquid flowing in through the water guide pipe 14 from flowing back into the gas guide pipe 13, and on the contrary, the other check valve 12 can prevent the gas flowing in through the gas guide pipe 13 from flowing back into the water guide pipe 14.

Meanwhile, a plurality of circles of spray pipes 8 are sleeved outside the cleaning pipe 3 positioned in the filter cylinder 2, the diameters of the upper and lower circles of spray pipes 8 are smaller than the inner diameter of the opening at the top of the filter cylinder 2 so as to be convenient for the filter cylinder to slide into the filter cylinder 2, the diameter of the opening in the spray pipe 8 is larger than the diameter of the cleaning pipe 3, wherein the inner side wall of the spray pipe 8 is connected with the cleaning pipe 3 through a plurality of groups of communicating pipes 9, and the side wall of the spray pipe 8 is evenly provided with spray holes 10, so that the spray pipe 8 is connected with the cleaning pipe 3 through the communicating pipes 9 to suspend the cleaning pipe in the filter cartridge 2, and the liquid or gas in the cleaning pipe 3 is injected into the spray pipe 8 through the communicating pipes 9, because the bottom end of the cleaning tube 3 is sealed, the gas or the liquid filled in the spray tube 8 can not flow out from the bottom of the cleaning tube 3, and then the gas or the liquid is sprayed out from the spray holes 10 on the 360-degree side wall of the spray tube, thereby enlarging the spraying area and improving the spraying effect, and obviously enhancing the cleaning and drying efficiency of the filter cylinder 2.

As a preferable scheme, an outlet end of the air inlet pipe 4 located in the chassis 1 is bent downward, so that liquid sprayed from the spraying holes 10 is not easily sprinkled into the outlet end of the air inlet pipe 4, wherein a water outlet pipe 19 for discharging cleaning liquid is arranged at the bottom of the chassis 1.

When the invention is used: the air duct 13 is connected with a compressed air pipe, the water guide pipe 14 is connected with a water pipe, the air outlet pipe 5 is connected with an air inlet pipe of an engine, when the engine works, air is continuously pumped, the air enters the case 1 from the air inlet pipe 4, the entered air passes through the filter cartridge 2 to filter particles in the air, the filtered air enters the engine from the air outlet pipe 5, after long-time work, the filter cartridge 2 needs to be cleaned, at the moment, a valve on the air outlet pipe 5 is closed, flushing water is injected into the spray pipe 8 from the water guide pipe 14 through the connecting pipe 11, the cleaning pipe 3 and the communicating pipe 9, the water is sprayed out from a plurality of spray holes 10 on the side wall of the spray pipe 8 to back flush the filter cartridge 3, flushing water is discharged from the water outlet pipe 19, after flushing is finished, the heated compressed air enters through the air guide pipe 13 and then back flushing is carried, while back flushing, hot compressed air evaporates the water remaining from the flushing process. The invention realizes the cleaning purpose by flushing and back flushing the filter cylinder 2, and the filter does not need to be disassembled in the cleaning process, thereby greatly improving the cleaning efficiency.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
