Specific embodiment
Referring to figs. 1 to Fig. 4, the embodiment of the multistage grease filter that this utility model band bypasses is described further.
A kind of multistage grease filter with bypass, including the filter of defecator, housing 1, interface channel 2 and at least two-stage
Cored structure 3, described filter cartridge construction 3 includes filter element 4, filter element cover 5, filter element import 6 and filter cartridge outlet 7, the filter element import 6 of upper level
It is provided with the bypass 8 opened in filter cartridge construction 3 blocking of upper level and the filter element import 6 of next stage between.
Described defecator includes housing 1, and described housing 1 is respectively provided on two sides with oils and fatss import and grease outlets, described
Oils and fatss import is connected with oils and fatss intake channel, and described grease outlets are connected with grease outlets passage, and described oils and fatss import is led to
Road is connected with filter cartridge construction 3, and described filter cartridge construction 3 includes filter element 4 and filter element cover 5；Described filter element cover 5 is enclosed within filter element 4
Periphery, described filter element mouth end face is additionally provided with filter element mouth sealing ring, and described multistage filter cartridge construction 3 is gone here and there by interface channel 2
Connection connects.
Filter element 4 in described filter cartridge construction 3 can be cylindrical filter cartridge, and the number of described filter element 4 is several, described
Cylindrical filter cartridge be set with one by one.
Filter element 4 in described filter cartridge construction 3 can also be chip filter element, and described filter element 4 number is several, described
Chip filter element be superimposed one by one.
By adopting technique scheme, when there is blocking in the filter cartridge construction 3 of upper level, the filter element import 6 of upper level
Place pressure increase, reach bypass 8 setting value when, bypass 8 connection, oils and fatss from bypass 8 entrance next stage filter element imports 6, so
Continue afterwards to filter, the filter cartridge construction 3 of rear class can be made full use of, reduce the working clearance, realize the high efficiency of filter process and hold
Continuous property.
For example, it is provided with altogether the filter cartridge construction 3 of three-level, respectively first order filter cartridge construction 3, second level filter cartridge construction 3 and
Third level filter cartridge construction 3, when there is blocking in second level filter cartridge construction 3, second level filter cartridge construction 3 and third level filter cartridge construction 3
Between bypass 8 connect, skip second level filter cartridge construction 3, oils and fatss be directly entered third level filter cartridge construction 3 proceed filter.
Preferably, described bypass 8 includes overflow valve 9 to the present embodiment, and the filter element of upper level is led in one end of described overflow valve 9
Import 6, its effluent head leads to the filter element import 6 of next stage.
By adopting technique scheme, when there is blocking in the filter cartridge construction 3 of upper level, the filter element import 6 of upper level
Place's pressure increases, and when reaching the setting value of overflow valve 9 in bypass 8, overflow valve 9 is opened, and oils and fatss are from the filter of bypass 8 entrance next stage
Core import 6, then proceedes to filter, can make full use of the filter cartridge construction 3 of rear class, reduce the working clearance, realize filter process
High efficiency and persistence；Overflow valve 9 can be with remotely control, and structure is simple, it is easy to accomplish the break-make of bypass 8.
Preferably, described bypass 8 also includes pressure regulator valve 10 to the present embodiment, described pressure regulator valve 10 be arranged at overflow valve 9 with
Between the filter element import 6 of one-level.
By adopting technique scheme, after bypass 8 is connected, pressure regulator valve 10 can adjust in bypass 8 as needed
Pressure of grease, prevent pressure excessive and the filter cartridge construction 3 of next stage is caused excessive filtration bear and affect filter effect or
The filter cartridge construction 3 causing next stage blocks.
