Abstract
The utility model relates to a novel rough filtration filter element for refueling, comprising an upper annular cover, a lower blocking cover, a connecting rod and an external filtering net, wherein an internal filtering net is arranged between the edges of the inner sides of the upper annular cover and the lower blocking cover, and a filtering layer is coaxially arranged between the external filtering net and the internal filtering net. According to the utility model, a bolt penetrating into the through hole of the connecting rod fixes the whole, the oil is filtered by the internal filtering net, the filtering layer and the external filtering net and is then discharged, various impurity particles are filtered, and a water absorbing membrane layer prevents the passing of water, thereby ensuring the safe and normal running of an automobile; and a great quantity of electric charge generated by contact and friction of the oil with the filter core is conducted to the ground by the upper annular cover, the lower blocking cover, the connecting rod, the internal filtering net and the external filtering net as well as a refueling machine body made of metal materials, thereby preventing fire caused by electrostatic discharge and ensuring the safe and normal work of the personnel and the gas station.
Description
Technical field
The utility model belongs to the fuel charger filtration art, especially a kind of Novel oiling coarse filtration filter core.
Background technology
Automobile needs constantly to replenish oil plant, the fuel charger that uses in each gas station is not quite similar, but oil plant generally all passes through coarse filtration and two processing procedures of fine filtering, wherein, a kind of common coarse filtration filter cartridge construction is as shown in Figure 1: comprise ring cowling 1, lower plug cover 5, connecting rod 7 and outer screen pack 3, outer screen pack is installed, the coaxial through hole 6 of making in coaxial installation one connecting rod on the lower plug cover, this connecting rod between upper ring cowling and the setting of lower plug cover parallel interval and the two outer ledge.During use, connecting rod is used for fixing, and oil plant is entered by upper ring cowling, discharges behind outer screen pack impurity screening.
Often be mixed with moisture in oil plant, these moisture can cause great corrosion to engine, can cause vibration, detonation even the damage of engine when serious.In addition, upper ring cowling, lower plug cover, connecting rod and outer screen pack are made by plastics, and oil plant is with after above-mentioned each parts repeatedly contact, rub, can produce a large amount of electric charges, if electric charge gathers too much, static discharge phenomenon can occur, the safety of personnel and gas station has been caused serious threat.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, the safe handling Novel oiling coarse filtration filter core.
The technical scheme that the utility model is taked is:
A kind of Novel oiling coarse filtration filter core, comprise ring cowling, lower plug cover, connecting rod and outer screen pack, outer screen pack is installed between the outer ledge of upper ring cowling and lower plug cover, coaxial installation connecting rod on the lower plug cover, it is characterized in that: between the inside edge of described upper ring cowling and lower plug cover filtering net is installed, outside coaxial installation filter course between screen pack and the filtering net.
And described upper ring cowling, lower plug cover, connecting rod, filtering net and outer screen pack are made by metal.
And, described filter course ring-shaped section and ring-shaped sawtooth pattern, surperficial near the filter course of filtering net is the suction rete, the filter course surface of close outer screen pack is filter paper layer.
And the seam crossing of described outer screen pack and filtering net is equipped with the seam baffle plate.
Advantage of the present utility model and good effect are:
In the utility model, the bolt that installs in the through hole of connecting rod is fixed integral body, oil plant is discharged after filtering net, filter course and outer screen pack filter, various impurity particles are by filtering, the suction rete stops passing through of moisture, guaranteed automobile safe, normally travel, when oil plant contacts with filter core, fricative a large amount of electric charges are made through metal material upper ring cowling, lower plug cover, connecting rod, filtering net and outer screen pack and fuel charger body conduct to the earth, prevent the fire that static discharge causes, guaranteed personnel and Safety of Gas Station, normal work.
Description of drawings
Fig. 1 is the outline drawing of prior art;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to sectional view;
Fig. 4 is the I section enlarged drawing of Fig. 3.
The specific embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of Novel oiling coarse filtration filter core, shown in Fig. 1～4, comprise ring cowling 1, lower plug cover 5, connecting rod 7 and outer screen pack 3, outer screen pack is installed between the outer ledge of upper ring cowling and lower plug cover, coaxial installation connecting rod on the lower plug cover is made a through hole 6 that runs through connecting rod in the connecting rod, innovation of the present utility model is: between the inside edge of described upper ring cowling and lower plug cover inner filtration is installed, 10, coaxial installation filter course 4 between screen pack and the filtering net outside.
In the present embodiment, filter course such as Fig. 3, shown in 4, its ring-shaped section and ring-shaped sawtooth pattern, filter course surface near filtering net is suction rete 9, filter course surface near outer screen pack is filter paper layer 8, to be filter course stack compacting mutually by suction rete and filter paper layer consists of, the suction rete adopts the compound high Fiber Materials of import, but its moment is moisture absorption, under the high pressure of fuel charger, and still can dehydration, when moisture in the oil plant greater than the suction rete absorbability the time, the suction rete can dwindle rapidly the filter bores aperture until complete closed is cut off the oil plant path, prevents that moisture from passing through.
For with oil plant contact, fricative charge-conduction to greatly, upper ring cowling, lower plug cover, connecting rod, filtering net and outer screen pack are made by metal, preferred anti-finger print steel plate.
Because filtering net and outer screen pack form by metal material coiling with holes, in order to prevent the contacted seam in two ends in transportation, destroyed when using, so the seam crossing of screen pack and filtering net is equipped with seam baffle plate 2 outside.
In the utility model, the bolt that installs in the through hole of connecting rod is fixed integral body, oil plant is discharged after filtering net, filter course and outer screen pack filter, various impurity particles are by filtering, the suction rete stops passing through of moisture, guaranteed automobile safe, normally travel, when oil plant contacts with filter core, fricative a large amount of electric charges are made through metal material upper ring cowling, lower plug cover, connecting rod, filtering net and outer screen pack and fuel charger body conduct to the earth, prevent the fire that static discharge causes, guaranteed personnel and Safety of Gas Station, normal work.
