The through-hole 81 of connection, the diameter range of through-hole 81 are 0.5-3mm.Pure diesel oil is just from through-hole after the filtering of third filter layer 33
81 enter diversion pipe 8, then are discharged outward by 8 water conservancy diversion of diversion pipe to oil outlet 12.
As shown in figure 3, the filter paper of the second filter layer 32 is wound on an outside filter core central tube 34, and the first filter layer 31
It is sheathed on the outside of the second filter layer 32, to form external filter core.The side wall of external filter core central tube 34 is hollow out wall, by first
Filter layer 31 and the filtered diesel oil of the second filter layer 32 just can continue through third filter layer 33, with by third filter layer 33 after
It is continuous to be filtered.The upper end of external filter core is provided with a upper end cover 35, and the lower end of external filter core is provided with a lower cover
36, external filter core is sheathed on outside internal core in a manner of it can dismantle, i.e., side of the external filter core central tube 34 can dismantle
Formula is sheathed on outside internal core skeleton 39, is located at innermost first filter layer 31 in this way and is crossed filter layer positioned at the second of outside
32 and third filter layer 33 can separate, in order to part dismounting and replacement.Upper end cover 35 can be by glue bonding or
Hot plate welding is Nian Jie with the upper end of the first filter layer 31, the second filter layer 32 and external filter core central tube 34, and upper end cover 35
Cooperated between outer wall and the inner wall of filter block sub-unit 1 by sealing ring.Lower cover 36 be also possible to by glue be bonded or
Person's hot plate welding is Nian Jie with the lower end of the first filter layer 31, the second filter layer 32 and external filter core central tube 34, and lower cover 36
Outer wall and shell 1 inner wall between cooperated by sealing ring.Further alternative, upper end cover 35 is provided with gas vent,
Venting plug 37 is provided in gas vent.It is further optional, same circumference is provided with several gas vents on upper end cover 35,
And a retaining ring 38 is provided on upper end cover 35 in a manner of it can dismantle, retaining ring 38 blocks venting plug 37, avoids venting plug 37
It falls.Further, since the filter paper for impregnating oil is more difficult through gas, and fuel system is inevitable there are gas
, thus venting plug 37 can by gas before filter faster be discharged to filtering after, can to avoid the too many gas of accumulation before filter and
Filter area is caused to reduce.
Continue as shown in figure 3, the lower end of element kit 3 is circumferentially equally spacedly provided with several first overhead kicks 7, first
Overhead kick 7 can be directly arranged on lower cover 36, and if the lower end of the inner cavity of shell 1 be accordingly circumferentially equally spacedly provided with
Dry the second overhead kick, element kit 3 can control the locking of itself and shell 1 by the cooperation of the first overhead kick 7 and the second overhead kick
Or it unclamps；When element kit 3 turns to gap of first overhead kick 7 between the second overhead kick, element kit 3 can take upwards
Out, when element kit 3, which turns to the first overhead kick 7, to be located at below the second overhead kick, two overhead kicks, which mutually block, is leaned on, element kit 3
Just it cannot take out upwards.When replacing element kit 3, when removing shell 2 from filter block sub-unit 1, shell 2 passes through the first overhead kick
7 and second the cooperation of overhead kick 7 element kit 3 can directly be taken out of together, to avoid remaining fuel oil one on element kit 3
It directly drips, to avoid fuel oil waste, and prevents pollution environment.It can make to be also by similar between external filter core and internal core
Overhead kick cooperation, and flange collar is provided on internal core, flange collar and external filter core are interference fitted to form sealing structure.Upper end cover
35 can also be cooperated with retaining ring 38 by overhead kick, with easy to disassemble.
As shown in figure 5, the connection and reasonable arrangement of the utility model, compact-sized, three-stage filtration, combustion are realized by three filter layers
When oil passes through the first filter layer 31, solid particle is blocked, and solid particle just cannot reach the second mistake after being blocked
Filtering layer 32, to achieve the effect that filtering solid particles by the first filter layer 31, and solid particle is not easy to folding tubular
First filter layer 31 has an impact.And the bulky grain water (free water) in water impurity drips when can penetrate the first filter layer 31, greatly
Particle water droplet forms bulky grain water droplet in the aggregation of the second filter layer 32；And the little particle water droplet (emulsified water) in water impurity passes through the
When one filter layer, little particle water droplet is assembled to form bigger particle water droplet, by becoming bigger particle when the second filter layer
Water droplet.Third filter layer 33 again filters down bulky grain water droplet, so as to prevent particle water from entering downstream, to reach thorough
Filter the effect of particle water impurity.Therefore, the utility model can effective filter small particles water droplet, be not susceptible to solid particle
It influences, so that oil water separator water-oil separating efficiency with higher in use be effectively ensured.Optionally, shell 2
Lower end is additionally provided with a valve module 4 that discharges water for the water that element kit 3 is filtered out from fuel oil to be discharged outward.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can be realized and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
