Abstract

The utility model relates to a dewatering and static-proof filter core which comprises an upper ring cover, a lower blockage cover and an outer filter screen, wherein the outer filter screen is arranged between the upper ring cover and the outer side edge of the lower blockage cover; the upper ring cover is coaxially provided with a sealing gasket; the bottom surface of the lower blockage cover is provided with a pressure spring; an inner filter screen is arranged between the upper ring cover and the inner side edge of the lower blockage cover; and a filter layer is arranged between the inner filter screen and the outer filter screen. According to the dewatering and static-proof filter core, the filter core is integrally arranged in a shell; the pressure spring presses the upper ring cover on an oil injection port of the shell; an oil material enters from the upper ring cover and is sequentially processed through the inner filter screen, the filter layer and an outer filter layer and then is discharged while various granular impurities and moisture are filtered, so that the cleanliness of the oil material is ensured, and an engine of an automobile is protected; and a large quantity of charges generated through the contact and the friction of the oil material are conducted to the ground through the upper ring cover, the lower blockage cover, the inner filter screen and the outer filter screen, so that the problem of fire hazards caused by static discharge is solved, and the safety of personnel and an oil filling station is ensured.

Description

A kind of filter core of the antistatic that dewaters

Technical field

The utility model belongs to the fuel charger filtration art, especially a kind of filter core of the antistatic that dewaters.

Background technology

The gas station provides oil plant to buy for automobile, these oil plants are in transportation or when storage, can be because the reasons such as condensation be sneaked into moisture, if not treated and directly add the mailbox of automobile, the oil plant that is mixed with moisture can corrode engine, can cause the vibration of engine, detonation even to damage when serious.And the filter core in common filter as shown in Figure 1: comprise ring cowling 2, lower plug cover 6, outer screen pack 4, outer screen pack is arranged between ring cowling and lower plug cover, covers coaxial installation seal washer 1 in pressed on ring, at lower plug cover bottom surface installation stage clip 7.During use, the filter core integral installation is in housing, and stage clip is pressed on upper ring cowling on the pouring orifice of housing, and oil plant enters from upper ring cowling, and after outer screen pack was processed, made oil-out was discharged from the housing.

From above-mentioned processing procedure as can be known, oil plant is the processing of the outer screen pack of process just, the moisture of sneaking in it can't filtering, very easily cause the damage of the engine of automobile, and, because upper ring cowling, outer screen pack and lower plug cover are made by plastics, oil plant contact, fricative electric charge gather very easily in a large number, and the personnel of gas station, the safety of equipment have been caused serious threat.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of a kind of filter core of the antistatic that dewaters of rational in infrastructure, safe handling is provided.

The technical scheme that the utility model is taked is:

A kind of filter core of the antistatic that dewaters, comprise ring cowling, lower plug cover, outer screen pack, outer screen pack is arranged between ring cowling and lower plug cover outer ledge, cover coaxial installation seal washer in pressed on ring, at lower plug cover bottom surface installation stage clip, it is characterized in that: a filtering net is installed between described upper ring cowling and lower plug cover inside edge, between filtering net and outer screen pack, filter course is installed.

And described upper ring cowling, lower plug cover, outer screen pack and filtering net are made by metal material.

And, the uniform a plurality of punchings of making that tilt of described filtering net.

And described filter course ring-shaped section and ring-shaped zigzag type is the suction rete near the filter course of filtering net surface, is filter paper layer near the filter course surface of outer screen pack.

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 filter core integral installation is in housing, stage clip is pressed on upper ring cowling on the pouring orifice of housing, oil plant enters from upper ring cowling, through filtering net, filter course and outer filter course are processed rear discharge successively, in this process, various granule foreigns, moisture is all by filtering, guaranteed the cleaning of oil plant, protected the engine of automobile, and, the oil plant contact, fricative a large amount of electric charge is through upper ring cowling, lower plug cover, filtering net and outer screen pack conduct to the earth, solved the disaster hidden-trouble problem that static discharge causes, guaranteed the safety of personnel and gas station.

The specific embodiment

Below in conjunction with embodiment, the utility model is further illustrated, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.

A kind of filter core of the antistatic that dewaters, as shown in Fig. 1～6, comprise ring cowling 2, lower plug cover 6, outer screen pack 4, outer screen pack is arranged between ring cowling and lower plug cover outer ledge, cover coaxial installation seal washer 1 in pressed on ring, stage clip 7 is installed in the lower plug cover bottom surface, and innovation of the present utility model is: between described upper ring cowling and lower plug cover inside edge, a filtering net 8 is installed, filter course 5 is installed between filtering net and outer screen pack.

In the present embodiment, filtering net is as shown in Fig. 2～4, in the filtering net uniform a plurality of punchings 9 of making that tilt, when filtering net is rolled up tubular, the uniform punching of tilting joins end to end and forms a spirality, as shown in the arrow in Fig. 4, oil plant enters through gap, punching both sides, then processes through filtering layer.

Filter course is as shown in Fig. 5,6, its ring-shaped section and ring-shaped zigzag type, surperficial near the filter course of filtering net is suction rete 11, filter course surface near outer screen pack is filter paper layer 10, to be filter course stack compacting mutually by suction rete and filter paper layer consists of, the suction rete stops passing through of moisture, but can allow passing through of oil plant.

For with oil plant contact, fricative charge-conduction to greatly, upper ring cowling, lower plug cover, filtering net and outer screen pack all conduct electricity, the preferred anti-finger print steel plate of its material.

Because filtering net and outer screen pack form by the metal material coiling, 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.
