Technical field

The utility model relates to a kind of three rank oil-water separation fuel strainers, especially can realize minute impurities in fuel oil, filtrating equipment that small water droplet is separated simultaneously.

Background technique

At present, known fuel oil-water separating and filtering device is made up of strainer (oil and water seperator), secondary filter two-stage filter usually.Fuel oil removes large particle in fuel oil and moisture through motor suction side strainer (oil and water seperator), the molecule on the pressure side secondary filter removing fuel oil.Current employing two-stage oil water separation filtering needs larger space, and cost is higher simultaneously.

Model utility content

The utility model is overcome in prior art to adopt two-stage filter to need the larger space shortcoming that cost is higher simultaneously, proposes a kind of three rank oil-water separation fuel strainers.

For achieving the above object, the utility model adopts following technological scheme:

A kind of three rank oil-water separation fuel strainers, is characterized in that: comprise filter box; The top of described filter box has intake layers; Fuel oil permeability tube is connected with in described intake layers; The bottom of described fuel oil permeability tube is for having the permeable formation of multiple permeability hole; The below of described fuel oil permeability tube is equipped with multilayer thick filtering net; The below of described thick filtering net arranges coalescence layer; The below of described coalescence layer is equipped with transport pipe; Described transport pipe divides multiple horizontal segment and vertical section, and the below of coalescence layer is the first horizontal segment transport pipe; Surface of contact between described first horizontal segment transport pipe and coalescence layer is permeable face; One end of described first horizontal segment transport pipe connects the first vertical section transport pipe, and the first vertical section transport pipe is positioned at the side of intake layers, thick filtering net and coalescence layer; Described first vertical section transport pipe connects the second horizontal segment transport pipe; The below of described second horizontal segment transport pipe arranges a separating layer; The surface of contact of described second horizontal segment transport pipe and separating layer is permeable face; The below of described separating layer is directly connected with the clean product pipe of access to engine; Described second horizontal segment transport pipe connects the second vertical section transport pipe; Described second vertical section transport pipe is directly connected to the liquid outlet of filter box.

Explanation and the further scheme of such scheme are as follows:

In such scheme, described first vertical section transport pipe and the second vertical section transport pipe are totally-enclosed transport pipe, there is not permeability hole.

Because technique scheme is used, the utility model compared with prior art has following advantages:

The utility model is by being integrated in the space can saving motor in a filter greatly by different filter mediums, simultaneously cost-saving.

Fig. 1 is structural representation of the present utility model.

In above accompanying drawing: 1, filter box; 2, fuel oil permeability tube; 3, thick filtering net; 4, coalescence layer; 5, the first horizontal segment transport pipe; 6, the first vertical section transport pipe; 7, the second horizontal segment transport pipe; 8, separating layer; 9, clean product pipe; 10, the second vertical section transport pipe.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described:

Embodiment: shown in Figure 1:

A kind of three rank oil-water separation fuel strainers, comprise filter box 1; The top of described filter box 1 has intake layers; Fuel oil permeability tube 2 is connected with in described intake layers; The bottom of described fuel oil permeability tube 2 is for having the permeable formation of multiple permeability hole; The below of described fuel oil permeability tube 2 is equipped with multilayer thick filtering net 3; The below of described thick filtering net 3 arranges coalescence layer 4; The below of described coalescence layer 4 is equipped with transport pipe; Described transport pipe divides multiple horizontal segment and vertical section, and the below of coalescence layer 4 is the first horizontal segment transport pipe 5; Surface of contact between described first horizontal segment transport pipe 5 and coalescence layer 4 is permeable face; One end of described first horizontal segment transport pipe 5 connects the side that the first vertical section transport pipe 6, first vertical section transport pipe 6 is positioned at intake layers, thick filtering net 3 and coalescence layer 4; Described first vertical section transport pipe 6 connects the second horizontal segment transport pipe 7; The below of described second horizontal segment transport pipe 7 arranges a separating layer 8; Described second horizontal segment transport pipe 7 is permeable face with the surface of contact of separating layer 8; The below of described separating layer 8 is directly connected with the clean product pipe 9 of access to engine; Described second horizontal segment transport pipe 7 connects the second vertical section transport pipe 10; Described second vertical section transport pipe 10 is directly connected to the liquid outlet of filter box 1; Described first vertical section transport pipe 6 and the second vertical section transport pipe 10 are totally-enclosed transport pipe, there is not permeability hole.

First layer filter medium is thick filtering net 3, and primary responsibility removes the large particle in fuel oil; Second layer filter medium is coalescence layer 4, also can be removed after the small water droplet in fuel oil returns and is combined into large water droplet gradually through this layer of filter medium time through medium sized solid impurity particle in filter medium simultaneously fuel oil; Third layer filter medium is separating layer 8, and after second layer filter medium, the large water droplet of coalescence can be stopped by hydrophobic separating layer 8 and to be separated by gravitational settling effect, and the fine solid particles impurity simultaneously in fuel oil also can be separated by separated layer.Finally clean fuel oil enters motor, in the collecting bowl that the liquid outlet that the moisture be filtered enters filter box 1 connects.

The utility model places three layer filtration medium in filter interior, fuel oil particle and moisture after this three layer filtration medium can be removed, thus ensure that clean fuel oil enters the inside of motor.

Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
