The specific embodiment

As shown in Figure 1 and Figure 2, single barrel of formula diesel oil of the three cores pre-filtrating equipment of described band bypass, comprise staving 2, bung 10, be arranged on absolute oil chamber 11, filter chamber 12 and three double-stage filtering filter cores 1 that are laid in staving 2 inside symmetrically of staving 2 inside, and be arranged on oil-in 3 on staving 2 shells, oil-out 4 and sewage draining exit 5, wherein double-stage filtering filter core 1 adopts the double medium filtration structure, and 12 of absolute oil chamber 11 and filter chambers are the boundary with dividing plate 8, and absolute oil chamber 11 is positioned at filter chamber 12 bottoms.Staving 2 is cylindrical staving, bung 10 usefulness bolts 15 are fixedly mounted on the staving 2, be useful on mobile suspension ring 13 in bung 10 outer setting, these suspension ring 13 make that also operation is lighter when opening bung 10 on the other hand, be provided with bracing frame 14 in staving 2 bottom outside in addition, make the integral filter device place more firm, more convenient operation.

Absolute oil chamber 11 is positioned at the bottom of staving 2, three double-stage filtering filter cores 1 are positioned at 11 tops, absolute oil chamber and are installed on each self-corresponding filter core mount pad 6, filter core mount pad 7 is installed in construction opening place corresponding on 11 upper baffle plates 8 of absolute oil chamber, and the inner chamber of double-stage filtering filter core 1 communicates with absolute oil chamber 11 by filter core mount pad 7.Bung 10 is provided with the exhaust outlet 6 that communicates with filter chamber 12 in addition, oil-in 3 is positioned at staving 2 middle and upper parts and communicates with filter chamber 12, oil-out 4 communicates with absolute oil chamber 11, and sewage draining exit 5 be arranged in parallel with filter core mount pad 7, also is provided with differential pressure transmitter device 9 on the staving 2 simultaneously.Solderless wrapped connection one by-pass line 16 between staving 2 outsides, oil-in 3 and oil-out 4 in addition, an end of by-pass line 16 is provided with valve 17, and oil-in 3 is provided with valve 17 with oil-out 4 ends.This by-pass line 16 can be implemented under the situation that continues fuel feeding and carries out more renew cartridge.

The course of work of single barrel of formula diesel oil of the three cores pre-filtrating equipment of this band bypass is: when at first restarting work at its first task or after changing inner filter core, open oil-in 3 and oil-out 4, close sewage draining exit 5, open the exhaust outlet 6 that is provided with on the bung 10 simultaneously, the gas of original existence in staving 2 inside and oil-out 4 pipelines is all discharged gradually, after treating that internal gas is all discharged, close exhaust outlet 6, this moment, this pre-filtrating equipment began operate as normal.Oil-in 3 and oil-out 4 are arranged on the valve 17 of oil-in 3 and oil-out 4 ends, control the break-make of oil-in 3 and oil-out 4 respectively.Diesel oil is after oil-in 3 flows into staving 2 inside, behind the ectonexine double-filtration through double-stage filtering filter core 1, enter double-stage filtering filter core 1 inside, and the dividing plate 8 that is provided with between double-stage filtering filter core 1 bottom and filter core mount pad 6 flows into absolute oil chambeies 11, the most after filtration, the diesel oil after purifying discharges and the input diesel engine is that it is used through oil-out 4.When normal filtration, the valve 17 that by-pass line 16 ends are provided with is in closed condition, and by-pass line 16 is disconnected.

In the whole process that single barrel of formula diesel oil of the three cores pre-filtrating equipment of this band bypass filters, be arranged on the pressure of 9 pairs of absolute oil chambeies of differential pressure transmitter device 11 and filter chamber 12 inner diesel oil on the staving 2, be unfiltered diesel oil and filter after the pressure of diesel oil detect and analyze pressure reduction between the two in real time, when the pressure reduction between the two reaches the alarming value of setting, differential pressure transmitter device 9 in time gives the alarm, and illustrates that this moment, double-stage filtering filter core 1 blocked need were in time changed.At this moment, close oil-in 3, open bung 10, take out inner blocked double-stage filtering filter core 1 and, open sewage draining exit 5 simultaneously, in time discharge being deposited in impurity around dividing plate 8 tops, the filter core mount pad 7, moisture etc. with its replacing.When changing double-stage filtering filter core 1, open the valve 17 of by-pass line 16 ends and connect by-pass line 16, thereby when changing double-stage filtering filter core 1, continue fuel feeding by by-pass line 16.

The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
