Description
Technical field
The utility model relates to an a kind of annex on the casing of the industry such as hydraulic pressure, lubrication, is specifically related to a kind of anti-dust air-strainer by multiple part combination.
Background technique
In hydraulic system, all need the oil box be designed with for holding fluid medium, for hydraulic system provides enough running fluid, oil box also has the function of cooling oil simultaneously.When system is from oil box oil suction, oil box can be made to form vacuum, tank pressure can be made during system oil return to increase, so an air-strainer must be designed with for the oil box of the hydraulic system of open type, be used for being communicated with fuel tank and air, when making to produce degree of vacuum and oil return during system oil suction, pressure increases.Air-strainer is oil box door together with air, plays the function of filtered air, does not allow air directly enter oil box, produces pollute fluid.Under common environment, air outside fuel tank is not quite contaminated, more existing air-strainer just can meet the filtering requirement to air, but in the environment that some dust are larger, common air-strainer is just difficult to meet the demands, filter not thorough, fluid is subject to pollution of atmosphere, often causes hydraulic fault.
Summary of the invention
Technical problem to be solved in the utility model is to provide the anti-dust of a kind of energy and the dismountable air-strainer of filter core.
The utility model solves the technological scheme that its technical problem adopts: a kind of anti-dust air-strainer, be made up of upper cover and lower casing, described lower casing is divided into two joints, upper joint is large cylinder, lower joint is little cylinder, large cylinder and little cylinder connecting place is porose communicates, coarse filtration net is provided with in the lower end of little cylinder, detachable filter core is provided with in large cylinder, described filter core is made up of metallic support cylinder and dust filtration net, the surrounding of described metallic support cylinder is provided with vent, described dust filtration net is arranged on metallic support cylinder, standing screw is provided with at the center of described large cylinder, the center of described upper cover is provided with the circular hole corresponding to standing screw, described standing screw from the circular hole of upper cover through rear by locking nut by upper cover locking.
As the improvement of technique scheme, described little cylinder is provided with the flange for being connected with casing or joint.
As another improvement of technique scheme, described little cylinder is provided with sealing gasket.
The beneficial effects of the utility model are: anti-dust air-strainer of the present utility model can prevent dust from entering mailbox through twice filtration effectively, improves the filter precision to air; In addition, filter core wherein can be changed and can reuse.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2, a kind of anti-dust air-strainer, be made up of upper cover 1 and lower casing 5, wherein, lower casing 5 is divided into two joints, upper joint is large cylinder 501, lower joint is little cylinder 502, large cylinder 501 and little cylinder 502 connecting place is porose communicates, be provided with coarse filtration net 7 in the lower end of little cylinder 502, in large cylinder 501, be provided with detachable filter core, filter core is made up of metallic support cylinder 4 and dust filtration net 2, the surrounding of metallic support cylinder 4 is provided with vent, and dust filtration net 2 is arranged on metallic support cylinder 4.Be provided with standing screw 8 at the center of large cylinder 501, the center of upper cover 1 is provided with the circular hole to standing screw 8 correspondence, and standing screw 8 passes the rear locking nut 3 that passes through by upper cover locking from the circular hole of upper cover.Little cylinder 502 is provided with the flange for being connected with casing or joint.In order to better sealing, little cylinder is provided with sealing gasket 6.As shown in Figure 2, air passes through the gap of upper cover 1 and lower casing 5 through dust filtration net 2, enters in large cylinder 501, through the coarse filtration net 7 of little cylinder 502 lower end, enters in casing.Air just enters casing through twice filtration, effectively prevents dust from entering casing, improves the filter precision to air.
Although describe mode of execution of the present utility model by reference to the accompanying drawings above, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
Claims (3)
