Description

A kind of centrifugal filter

Technical field

The utility model relates to filter manufacturing technologies, in particular to centrifugal filter.

Background technique

Centrifugal filter is the characteristic different with the density of oil product using the impurity in oil product, will be in oil product using centrifugal force Impurity separation, the pressure that power resources have the flowing of outer power and oil pipe to generate；

Application No. is CN201520679484.7, disclose a kind of centrifugal oil filter, it is characterized in that devise it is special Bend, structure is more complicated.

In actual application, centrifugal filter is compared to the filter using filter paper, and structure is more complicated, manufacturing cost It is higher, it is used in relatively in actual filtering, effect is suitable with common filter, therefore uses the ratio of centrifugal filter at present It is less, currently on the market or based on filter paper filter.

The structure of centrifugal filter is simplified, it is contemplated that target be to reduce manufacturing cost, to realize more common application.

Summary of the invention

The utility model against the above deficiency, proposes a kind of more easy centrifugal filter of structure.

A kind of centrifugal filter includes shell, bottom cover, fuel feed hole, central tube, blocking arm, channel, which is characterized in that described The upper surface of shell is provided with spiral lamination, and the bottom cover is arranged below shell and seals the shell, and fuel feed hole is located at institute Bottom cover center, the fuel feed hole and central tube connection are stated, two nozzle openings, the spray of nozzle opening is arranged in the upper side of the central tube Oily direction is inclined relative to the central tube, and the blocking arm is arranged above bottom cover, and one end is fixed at shell and bottom The infall of lid, other side tilt certain angle, spiral convex tract are arranged below the bottom cover, the side of spiral convex tract is provided Oilhole has the first oil outlet and the first oil outlet respectively.

Further, on the central tube be arranged two nozzle openings, the duct of nozzle opening be it is inclined, oil spout route with Circle tangent line approach at oil drop out.

The utility model designs simpler construction, shell in original centrifugal filter principle, and bottom cover uses punching press Construction, manufacturing cost is lower, and structure is also more compact.

Fig. 2 is the upper shell face schematic diagram of the utility model embodiment.

Fig. 3 is the bottom cover front view of bottom.

Fig. 4 is bottom cover sectional view.

Specific embodiment

The utility model is described in detail below with reference to specific embodiments and the drawings.

Fig. 1-5 is please referred to, centrifugal filter, such as Fig. 1 are shown, includes shell 1, bottom cover 2, fuel feed hole 3, central tube 4, blocking arm 5, channel 6, the upper surface of shell 1 are provided with spiral lamination 12, and bottom cover 2 is arranged below shell 1 and seals shell 1, fuel feed hole 3 Positioned at 2 center of bottom cover, two nozzle openings, the respectively first spray is arranged in fuel feed hole 3 and 4 connection of central tube, the upper side of central tube 4 Oilhole 41 and the second nozzle opening 42, channel 6 is interior to be arranged central tube 4, and through-hole 7 is arranged in channel 6.

Such as Fig. 2, the shape of spiral lamination 12 is illustrated, the effect of spiral lamination 12 is the oil product rotation driven in shell 1.

Oil spout direction p such as Fig. 5, the first nozzle opening 41 is inclined relative to central tube, and two oil spouts are arranged on central tube Hole, the duct of nozzle opening be it is inclined, oil spout route is approached with the circle tangent line at oil drop out, and the purpose is to be generated using oil spout Powered shell 1 rotate, the second nozzle opening 42 is identical as 41 structure of the first nozzle opening.

Specifically, blocking arm 5 is arranged above bottom cover 2, and one end is fixed at the infall of shell 1 Yu bottom cover 2, in addition Side tilts certain angle, and blocking arm is a upside down funnel shape, the purpose is to allow impurity without falling into in oil outlet, impurity is allowed to stop The edge for staying in shell forms a storage contaminant space.

Such as Fig. 3-4, spiral convex tract 21 is set, the side of spiral convex tract 21 is arranged oil outlet, there is first respectively below bottom cover 2 Oil outlet A and the first oil outlet B.During fuel-displaced, there is a reaction force, allow and bottom cover 2 is pushed to rotate, and then pushes shell Rotation, in shell 1 constantly rotary course, impurity under the action of the centrifugal force, is accumulated in the lower end of shell 1, is kept off by blocking arm 5 Firmly, clean oil product can be then fuel-displaced from the first oil outlet A and first toward flowing at center, then down into 2 top of bottom cover It is flowed out at the B of hole, when flowing outward, gives 2 reaction force of bottom cover.

It should be noted that the oil that nozzle opening sprays will push the rotation of shell 1, the first oil outlet A and the first oil outlet B spray Oil out can also push shell to rotate in reaction force, and the necessary direction of two active forces is consistent, can not if cancelling out each other Generate filtration.

Need to reduce to the greatest extent friction in rotary course, therefore outside needs that lubricating oil is arranged at fuel feed hole 3.

The implementation steps of the utility model are that fuel oil enters in filter, and fuel oil has certain pressure, oily from fuel feed hole 3 up move, and spray oil from the second nozzle opening 42 and the first nozzle opening 41, and there is certain inclination in oil spout direction, can push outer Shell 1, the utility model design simpler construction in original centrifugal filter principle, especially make full use of oil stream dynamic The pressure of generation pushes the shell constantly to rotate.

The utility model is most of to use stamping parts since main component structure is simpler, and manufacturing cost can drop significantly It is low.

Above disclosed is only a kind of preferred embodiment of the utility model, certainly cannot be practical to limit with this Novel interest field, therefore equivalent variations made according to the claim of the utility model still belong to what the utility model was covered Range.
