Abstract

The utility model discloses a filter element assembly, comprising a center pipe. The outer side of the center pipe is provided with a filter net in a surrounding mode, and the upper end and the lower end of the center pipe and the filter net are correspondingly provided with an upper end cover and a lower end cover. The upper end cover and the lower end cover are provided with magnet bodies at intervals in the positions corresponding to the relevant end surface of the filter net. The filter element assembly effectively solves the technical problem that a lot of impurities block outer filter net meshes. When fuel oil flows to the filter net by the center pipe, large particles of impurities mingled in the fuel oil are absorbed by the magnet bodies, so that the impurities flowing to the filter net are reduced. After an oiling machine filter adopts the filter element assembly, after a period of time of using, the filter can be disassembled, a filter element is cleaned, and the cleaned filter element can be repeatedly used, so the pollution of the discarded filter element of the existing filter for environment is reduced. The filter element assembly has the advantages of simple structure, economy and practicality.

Description

A kind of filter core assembly

Technical field

The utility model relates to a kind of filter core assembly, particularly a kind ofly is applied to the filter core assembly that filter fuel is used in the fuel charger.

Background technology

In oiling machine hydraulic system, filter is the reliability that guarantees clarifying fuel oil, the work of raising fuel charger, the key components that prolong service life of equipment, be mainly used in and filter product oil impurity, make oil product pure, guarantee oil quality, reduce the wearing and tearing of fuel charger flowmeter simultaneously, guarantee measuring accuracy.Domestic fuel charger major part all adopts spin-on filter, life cycle is 1-February only, the statistics of present domestic gas station sum shows more than 100,000,4,000,000 of the consumptions of annual fuel charger filter cause the environmental pollution of a large amount of wastings of resources and waste and old filter (no recovery value).

Filter core assembly generally includes central tube, and central tube is provided with the open-work of the fuel oil that is used to circulate, and is surrounded with screen pack in the central tube outside, and the upper/lower terminal correspondence of this central tube and screen pack is provided with upper and lower two end caps.During use, fuel oil enters central tube by oil-in, flows to screen pack through central tube, flows out behind the net filtration after filtration.

Because the filtration to fuel oil has higher requirement, and the screen pack in the above-mentioned filter core assembly is a single layer structure, in order to guarantee filter effect, the order number of individual layer filter screen is bigger usually, often stop up the filter efficiency that the screen pack mesh has reduced filter core in a large number so in use for some time because of impurity, thereby reduced the flow velocity of fuel oil, influenced the flow of fuel charger, further influenced the functional reliability of fuel charger.

The utility model content

The purpose of this utility model provides a kind of filter core assembly, uses this filter core assembly can solve the technical problem that impurity in the prior art stops up filter screen in a large number.

The technical solution of the utility model is: a kind of filter core assembly, comprise central tube, the described central tube outside is surrounded with screen pack, upper/lower terminal correspondence at central tube and screen pack is provided with upper and lower end cap, and upper and lower end covers in the position corresponding with the screen pack corresponding end-faces and is laid with the magnet body at interval.

Be formed with magnet body containing groove on the inner surface of described upper and lower end cap, each magnet body is positioned at corresponding magnet body containing groove.

The magnet body that described upper and lower end covers is all along the circumferential direction evenly laid.

Described screen pack by outer filter and in the inner filter screen that is lining in the outer filter constitute, the order number of this inner filter screen is less than the order number of outer filter.

Described magnet body is by stacked the forming of plural circular magnet sheet.

The utility model can effectively solve the technical problem that impurity stops up the outer filter mesh in a large number, when fuel oil when central tube flows to screen pack, the large granular impurity that is mixed in the fuel oil will be adsorbed by the magnet body, so just reduce the impurity that flows to screen pack.After the fuel charger filter adopts the utility model filter core assembly, use a period of time filter assembly can be taken apart, cleaning filter core, reusable behind the cleaning filter core, reduced of the pollution of the discarded filter core of existing filter to environment.The utility model is simple in structure, and is economical and practical.

The containing groove that matches with the magnet body in the integrally formed setting of upper and lower end cap medial surface can easily be realized the positioning and fixing of magnet; The upper and lower end cap of this structure is simple in structure, can be by the punching press one-shot forming, and production cost is low.

Because fuel oil flows to screen pack by central tube, so in outer filter behind the less inner filter screen of sidelining order number, can fall by the contaminant filter of inner filter screen the larger particles in the fuel oil, and filter impurity than granule by the bigger outer filter of outer order number, prevent that outer filter is blocked, so just improve the utilization rate of outer filter, and prolonged the outer filter maintenance period, further improved service efficiency.

The magnet body can further be strengthened big material impurity in the filter fuel like this by stacked the forming of plural circular magnet sheet.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

The specific embodiment

Figure 1 shows that a kind of embodiment of the utility model filter core assembly, this filter core assembly comprises central tube 3, this central tube 3 is provided with the open-work 6 of the fuel oil that is used to circulate, be surrounded with screen pack 2 in the outside of central tube 3, described screen pack 2 comprises outer filter and the inner filter screen of liner on the outer filter medial surface, wherein the order number of inner filter screen is less than the order number of outer filter 2, on central tube 3 and screen pack 2, following two ends correspondence is provided with upper end cover 1 and bottom end cover 8, on, bottom end cover is laid with magnet body 7 at interval in the position corresponding with the screen pack corresponding end-faces, on described, be formed with magnet body containing groove 9 on the inner surface of bottom end cover, each magnet body 7 is positioned at corresponding magnet body containing groove 9, and described magnet body 7 can evenly be laid around circumferencial direction.

During concrete enforcement, magnet body 7 can be a monoblock magnet body, also can be by some stacked the forming of circular magnet sheet, and the quantity of circular magnet sheet can be set according to concrete needs.In addition, the cross section of magnet body 7 also can be square or trapezoidal other shapes that waits.

During concrete enforcement, inside and outside two-layer filter screen order number differs can be bigger, select 220 order stainless (steel) wires for use such as outer filter, and inner filter screen can be selected 30 purpose steel wires for use, so both can reach the purpose of effective removing impurities particle, also improve the utilization rate of inside and outside two-layer filter screen.

Recycle after inside and outside metafiltration net in the utility model filter core assembly is capable of washing, recycle after magnet is also capable of washing.
