The specific embodiment

First preferred implementation, as Fig. 1, shown in Figure 2, the parallel diesel oil pre-filtrating equipment of described rectangle twelve-core, compose in parallel by two separate rectangle twelve-core diesel oil pre-filtrating equipments, its each diesel oil pre-filtrating equipment includes upper end open and floor space is the cube housing 2 of rectangle, case lid 10, be arranged on the absolute oil chamber 11 of housing 2 inside, filter chamber 12 and 12 double-stage filtering filter cores 1 that are laid in housing 2 inside symmetrically, and be arranged on oil-in 3 on the housing 2, oil-out 4 and sewage draining exit 5, wherein 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.Case lid 10 usefulness bolts 15 are fixedly mounted on the housing 2, and the bottom outside of housing 2 sidewalls is provided with the hook 16 of mobile usefulness.Be provided with bracing frame 14 in housing 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 housing 2,12 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, and oil-in 3 is positioned at housing 2 middle and upper parts and communicates with filter chamber 12, and oil-out 4 communicates with absolute oil chamber 11, and sewage draining exit 5 be arranged in parallel with filter core mount pad 7.Be interconnected between the oil-in 3 of two diesel oil pre-filtrating equipments simultaneously, be interconnected between the oil-out 4, and on housing 2, also be provided with differential pressure transmitter device 9.

The course of work of the parallel diesel oil pre-filtrating equipment of this rectangle twelve-core is: for each diesel oil pre-filtrating equipment, 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 on the bung 10 exhaust outlet 6 that is provided with simultaneously, the gas of original existence in housing 2 inside and oil-out 4 pipelines all discharged gradually, treat that internal gas is all discharged after, close exhaust outlet 6, this moment, this pre-filtrating equipment began operate as normal.Diesel oil is after oil-in 3 flows into housing 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 is discharged and is input to through oil-out 4 needs the occasion that uninterruptedly carry out quick filtration treatment to diesel oil and need big flow supply clean diesel.

In the whole process that the parallel diesel oil pre-filtrating equipment of this rectangle twelve-core 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 housing 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.Two diesel oil pre-filtrating equipments can work alone separately, also can work simultaneously.When one of them diesel oil pre-filtrating equipment is changed double-stage filtering filter core 1, another diesel oil pre-filtrating equipment can continue operate as normal, thereby be implemented under the situation that continues to filter and change double-stage filtering filter core 1, guarantee to continue, filter incessantly and fuel feeding.

Second preferred implementation, as shown in Figure 3, differential pressure transmitter device 9 on the housing 2 of the parallel diesel oil pre-filtrating equipment of described rectangle twelve-core in corresponding first preferred implementation, be provided with the pressure indicator 13 with positive and negative deixis, other part-structures, the course of work are identical with first preferred implementation.This pressure indicator 13 detects the pressure of filter chamber 12 with absolute oil chamber 11 inner diesel oil respectively, and shows the pressure reduction between the two.When double-stage filtering filter core 1 does not stop up, the pressure reduction during its normal filtration between filter chamber 12 and the absolute oil chamber 11 be on the occasion of, this moment pressure indicator 13 indicated value be on the occasion of; Blocked and can't normal filtration the time when double-stage filtering filter core 1, because filter chamber 12 is a negative value with pressure reduction between the absolute oil chamber 11, the indicated value of pressure indicator 13 be a negative value at this moment.In the whole process that the parallel diesel oil pre-filtrating equipment of this rectangle twelve-core filters,, illustrate that double-stage filtering filter core 1 blocked need in time change if when the indicated value of pressure indicator 13 is negative value.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.

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.
