Description
Technical field
The invention belongs to art of filters, specifically, it is with regard to a kind of detachable rotary filter of modified model and its mistake
The method of filter fluid.
Background technology
Rotary filter is the cleaner kind with filter paper as filter material growing up nineteen seventies, rotary filter
Clear device compact conformation, lightweight, using reliability, maintaining is convenient, is widely used in electromotor and hydraulic system.According to existing
There is data incomplete statistics, using rotary filter more than 90% in automobile engine, using spinning on engineering machinery engine
Cleaner is also above 80%.
But rotary filter also has obvious defect, as shown in figure 1, rotary filter generally includes sealing ring 1, threaded cap
Plate 2, filter housing 3, filter element 4 and spring 5, described filter element 4 includes inner frame 42, bypass valve 43, filter material 41 and end cap 44, these zero
Part be all by riveting, welding, cementing by way of connect into an entirety.When filter element 4 blocks, rotary filter palpus is overall more
Change, so that the other parts originally being continuing with addition to filter material 41 is also replaced, cause greatly to waste, meanwhile, filter housing 3
The medium that interior federation residual is filtered, to environment after discarding.
In order to solve the above problems, Chinese patent cn2051117442u discloses a kind of detachable rotary filter, including
Filter housing 10, sealing gasket 11, coupling head 12 and the filter element 13 located at coupling head 12 lower section, described sealing gasket 11 is crushed on coupling head 12
And filter housing 10 between, coupling head 12 and filter housing 10 are threaded connection, and are provided with some fuel feed holes 14, center in described coupling head 12

In 12 centre bore 15 and the endoporus 133 of filter element 13.But this patent there are the following problems:
1st, its installation and removal is inconvenient, during filter element replacing, needs first filter element 13 to be backed out from coupling head 12, if interior
Have on skeleton 17 and be carried out in addition it is also necessary to pull down inner frame 17 during pollutant;During installation, need for inner frame 17 to insert connection
12 centre bore 15, then filter element 13 is entangled inner frame 17, and by the screw thread on the end cap 131 of filter element 13 and coupling head 12
Screwed tight, it is complicated that it entirely mounts and dismounts process;
2nd, because bypass valve is arranged in the counterbore 16 of coupling head 12, lead to the volume of bypass valve less than normal, excessively stream effect is not
Enough ideals.
Therefore, it is necessary to designing, a kind of excessively stream effect is good, mount and dismount convenient rotary filter.
