The specific embodiment

First preferred implementation, as Fig. 1, Fig. 2 and shown in Figure 3, described square 16 core diesel oil pre-filtrating equipments, comprise that upper end open and floor space are foursquare cube housing 2, case lid 10, be arranged on the absolute oil chamber 11 and filter chamber 12 of enclosure interior, and 16 double-stage filtering filter cores 1 that are laid in housing 2 inside symmetrically, offer oil-in 3 on the wherein said housing 2, oil-out 4 and

sewage draining exit

Described 16 double-stage filtering filter cores 1 are laid in housing 2 inside symmetrically, and housing 2 sidewalls are provided with differential pressure transmitter device 9 simultaneously, and the bottom outside of housing 2 sidewalls is provided with the hook 14 of mobile usefulness.Case lid 10 is fixedly mounted on the housing 2 by bolt 15, constitutes the shell structure of sealing, and housing 2 bottom outside are provided with bracing frame 16 simultaneously.

The course of work of these square 16 core diesel oil pre-filtrating equipments 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 case lid 10 simultaneously, the gas of original existence in housing 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 of oil-in 3 and oil-out 4 ends, control the break-make of oil-in 3 and oil-out 4 respectively.After diesel oil enters filter chamber 12, 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 chamber 11, the most after filtration, the diesel oil after purifying discharges through oil-out 4, and be input to and need carry out quick filtration treatment and need the occasion of big flow supply clean diesel diesel oil.

Carry out in the whole process of normal filtration at these square 16 core diesel oil pre-filtrating equipments, be arranged on the differential pressure transmitter device 9 on housing 2 sidewalls, to the pressure of absolute oil chamber 11 with filter chamber 12 inner diesel oil, 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.When double-stage filtering filter core 1 blocked need are in time changed, close oil-in 3, open case lid 10, take out inner blocked double-stage filtering filter core 1 and its replacing, open sewage draining exit 5 simultaneously, in time discharge being deposited in impurity around dividing plate 8 tops, filter core mount pad 7, moisture etc.

Second preferred implementation, differential pressure transmitter device 9 in corresponding first preferred implementation of these square 16 core diesel oil pre-filtrating equipments, be provided with the pressure indicator with positive and negative deixis, other part-structures, the course of work are identical with first preferred implementation.This pressure indicator 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 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 be a negative value at this moment.In the whole process that this square 16 core diesel oil pre-filtrating equipments filter,, illustrate that double-stage filtering filter core 1 blocked need in time change if when the indicated value of pressure indicator 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.
