Abstract
The utility model relates to a dewatering anti-static rough-filtration filter element used for an oiling machine. The dewatering anti-static rough-filtration filter element comprises an upper annular cover, a lower blocking cover and an outer filtering net, wherein the outer filtering net is arranged between the outer side edges of the upper annular cover and the lower blocking cover, an inner filtering net is arranged between the inner side edges of the upper annular cover and the lower blocking cover, and a filtering layer is coaxially arranged between the outer filtering net and the inner filtering net. According to the dewatering anti-static rough-filtration filter element, the inner filtering net, the outer filtering net and the filtering layer are matched with one another; after rough filtration treatment, impurity particles left in oil can be further removed by filtering, and absorbent cotton prevents water from passing, thereby avoiding the damage to an engine caused by the oil containing water; and since the upper annular cover, the lower blocking cover, the inner filtering net and the outer filtering net are all made of a metal material, generated electric charges can be conducted to the ground by an oiling machine body, thereby preventing fire caused by electrostatic discharge and ensuring the safe and normal work of personnel and a filling station.
Description
Technical field
The utility model belongs to the fuel charger filtration art, and especially a kind of fuel charger is with the antistatic coarse filtration filter core that dewaters.
Background technology
Automobile is when refueling, impurity in the oil plant etc. enters the fuel tank of automobile, filter is installed in fuel charger, two kinds of filter cores of coarse filtration and fine filtering are installed in it, wherein, the filter cartridge construction of fine filtering is as shown in Figure 1: comprise ring cowling 1, lower plug cover 5 and outer screen pack 3, upper ring cowling and lower plug cover parallel interval arrange and the two outer ledge between outer screen pack is installed.During use, oil plant is entered by upper ring cowling, discharges behind outer screen pack impurity screening.
Owing to reasons such as condensations, often by moisture contamination, these moisture can cause great corrosion to engine at oil plant, can cause vibration, detonation even the damage of engine when serious.In addition, upper ring cowling, lower plug cover 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, provides a kind of fuel charger of rational in infrastructure, safe handling with the antistatic coarse filtration filter core that dewaters.
The technical scheme that the utility model is taked is:
A kind of fuel charger is with the antistatic coarse filtration filter core that dewaters, comprise ring cowling, lower plug cover and outer screen pack, outer screen pack is installed between the outer ledge of upper ring cowling and lower plug cover, it is characterized in that: between the inside edge between described upper ring cowling and the 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, 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, filtering net, outer screen pack and filter course three cooperatively interact, after coarse filtration is processed, remaining impurity particle in the further filtering oil plant, absorbent wool stops passing through of moisture, has avoided containing the oil plant of moisture to the damage of engine, upper ring cowling, lower plug cover, filtering net and outer screen pack are metal material and make, the electric charge that produces is conducted to the earth through the fuel charger body, 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 that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the I section enlarged drawing of Fig. 2.
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 fuel charger is with the antistatic coarse filtration filter core that dewaters, shown in Fig. 1～3, comprise ring cowling 1, lower plug cover 5 and outer screen pack 3, outer screen pack is installed between the outer ledge of upper ring cowling and lower plug cover, innovation of the present utility model is: filtering net 8, outside coaxial installation filter course 4 between screen pack and the filtering net are installed between the inside edge between described upper ring cowling and the lower plug cover.
In the present embodiment, filter course is shown in Fig. 2,3, and its ring-shaped section and ring-shaped sawtooth pattern is suction rete 7 near the filter course of filtering net surface, is filter paper layer 6 near the filter course surface of outer screen pack.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 with moisture absorption, under the high pressure of fuel charger, still can dehydration, when moisture in the oil plant during greater than the absorbability of suction rete, the suction rete can dwindle rapidly the filter bores aperture until complete closed, the oil plant path is cut off, prevent that moisture from passing through.
For with oil plant contact, fricative charge-conduction to greatly, upper ring cowling, lower plug cover, 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, filtering net, outer screen pack and filter course three cooperatively interact, after coarse filtration is processed, remaining impurity particle in the further filtering oil plant, absorbent wool stops passing through of moisture, has avoided containing the oil plant of moisture to the damage of engine, upper ring cowling, lower plug cover, filtering net and outer screen pack are metal material and make, the electric charge that produces is conducted to the earth through the fuel charger body, prevent the fire that static discharge causes, guaranteed personnel and Safety of Gas Station, normal work.
