Description
Technical field
The invention belongs to oil filter field, it is related to a kind of central tube, without metal environment-friendly filter element and rotatable filter,
More particularly to a kind of double-layered central pipe, the rotation without metal environment-friendly filter element and use the double-layered central pipe using the double-layered central pipe
Dress formula filter.
Background technique
Currently, the mounting means of many spinning oil filter is formal dress, i.e., the machine oil mouth entrance of rotary filter and go out
The direction of mouth is contrary with the earth's core, therefore under engine off condition, by gravity, machine oil automatic storage is in rotary filter
In clear device tank body, but still the installation direction for having very multiengined oil filter arrangement is the anti-dress (machine oil of rotary filter
Mouthful entrance and exit is towards the earth's core), therefore machine oil can return to oil sump due to gravity under shutdown status, when engine again
When secondary starting, machine oil is then each to engine by the oil delivery of filtering again firstly the need of the tank body for being full of rotary filter
Oil site, the machine oil due to being transported to oil site have delay, and disadvantage is it is clear that in order to solve this latency issue, part machine
Oil rectifier manufacturer increases the device of a check-valves in the clean side of machine oil of rotary filter, and work caused by this check-valves
Skill and cost can also increase therewith.
Chinese patent CN203321624U discloses a kind of rotary mounting engine oil filter for automobile, the rotation fitting type machine oil
The through-hole of more than two numbers is distributed in the tube wall of the central tube of filter, any one through-hole to central tube bottom face away from
Axial length from the half for being all larger than central tube.When the rotary mounting engine oil filter works, the part below through-hole, machine
Oil is through filtration core, after pipe outer wall rises to through-hole along center later, generates very more flow resistances, while inside and outside the filter material of through hole
Pressure difference is smaller, causes the utilization rate of entire filter core from top to bottom that cannot be fully exploited, poor filtration effect.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of central tube, without metal
Environment-friendly filter element and rotatable filter.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of central tube, including the inner barrel and outer barrel being coaxially arranged and bottom connects, between the inner cylinder and outer cylinder
Equipped with gap, multiple filtering windows are offered on outer tube side wall, inner cylinder side wall is continuous structure, and the height of inner cylinder is lower than the height of outer cylinder
Degree.
Preferably, multiple filtering windows are uniformly provided on outer tube side wall, a part of filtering window on outer tube side wall is located at interior
Cylinder top.
The area for being preferably located at the filtering window above inner cylinder accounts for the 1/5~1/3 of the filtering window gross area.
It is further preferred that the area for the filtering window being located above inner cylinder accounts for the 1/4 of the filtering window gross area.
Preferably, the filtering window is top cap window, and the percent opening of outer tube side wall is 90~95%.
Preferably, the inner cylinder is equal wall thickness tubular structure, and outer diameter is tapered from top to bottom, between outer cylinder and inner cylinder between
Gap becomes larger from top to bottom.
A kind of no metal environment-friendly filter element, including filter element body, the filter element body center are equipped with coaxial aperture, filter element body
Both ends be equipped with upper end cover and lower cover, the central tube is equipped in the coaxial aperture, the central tube is nonmetallic
Material central tube.
A kind of rotatable filter, tank body, setting including bottom end opening in the intracorporal filter core of the tank and are connected to this
The end cap of tank body bottom end, the filter core include filter element body, and the filter element body center is equipped with coaxial aperture, filter element body
Both ends are equipped with upper end cover and lower cover, and the central tube is equipped in the coaxial aperture, and end cap is equipped with machine oil import and machine
Oil export, machine oil outlet are connected with the inner cylinder of central tube.
Preferably, which further includes by-passing valve, and the top in outer cylinder is arranged in the by-passing valve.
The operation principle of the present invention is that:
Central tube of the invention is suitable for the anti-rotatable filter filled and (exports when installation equipped with machine oil import and machine oil
End cap is downward), using the rotatable filter of the central tube in the state that engine is shut down, the inner cylinder of central tube and inner cylinder top
Sealing area is formed between portion's tank body below, machine oil still can store in the sealing area, when engine is again started up,
Machine oil can be full of tank body, rapid delivery engine lubrication point after filtering within the very short time, to save dry in machine oil
The space of net side arrangement check-valves and cost.
Compared with prior art, the invention has the following advantages:
(1) structure is simple, safe and reliable: relative to needing to install check-valves in clean side, center tube structure is simple, arrangement
It is very convenient, reliable operation, the problem of being not present similar to non-return defective valve.
(2) filter efficiency is high: double-layered central pipe structure (inner and outer tubes) provides not only fluid into clean inner tube
Runner gap, and the utilization rate of filter core is more balanced, to help engine more energy-saving and emission-reduction.And in shutdown status
Under can store more machine oil, reduce the time that oil delivery is reached to after engine start each oil site；Outer cylinder and inner cylinder
Between gap become larger from top to bottom, further increase the machine oil amount of storage under shutdown status.
(3) use scope is wide: length, diameter and percent opening of outer tube filtering window of the inner tube of central tube etc. can be according to not
Same filter core carries out seriation exploitation.
(4) production cost is low: the central tube, which is avoided, installs check-valves in clean side, has saved production and assembling cost.
(5) long service life: the PA66+GF30 with excellent ageing-resistant ability can be used in central tube, is effectively ensured
Service life.
