Abstract
The utility model discloses an air filter which comprises a protective casing component, a paper filter core and a safe filter core, and is characterized by comprising a sand receiving disc component which is laterally plugged in a hollow cavity between the protective casing component and the paper filter core. The air filter can prevent hydraulic oil in an oil tank from splashing to the paper filter core, prolongs the service span of the paper filter core, guarantees the balance of pressure in the oil tank and atmosphere pressure, can conveniently clear accumulated sand in the air filter, and effectively guarantees the cleanness of oil in the oil tank.
Description
Technical field
The utility model relates to a kind of air filter.
Background technology
At present; common empty filter dust storm enters into and is difficult to cleaning in the sky filter; and the air inlet position and the fuel tank liquid level difference in height that are provided with are very little, in case fuel tank takes place than big bang, hydraulic oil is easy to overflow in fuel tank; filter core is got wet; influence pressure and atmospheric pressure balance in the fuel tank, in a single day the hydraulic oil that overflows mix with the grains of sand that enter into the sky filter, and time one length will produce greasy filth; stop up air admission hole, and then influence the operate as normal of hydraulic system.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of can prevent that the hydraulic oil in the fuel tank is splashed on the paper filter element, but the while easy cleaning enters the empty filter of the sand and dust in the sky filter.
The utility model is realized by following measure:
Empty filter of the present utility model comprises protective acoustic cover assembly, paper filter element and safe filter core, it is characterized in that: comprise connecing the sand table assembly described connecing in the cavity of the horizontal shutoff of sand table assembly between protective acoustic cover assembly and paper filter element.
Empty filter of the present utility model, described connect between sand table assembly and the protective acoustic cover assembly and connect be equipped with the O RunddichtringO between sand table assembly and the paper filter element.
Empty filter of the present utility model, the described sand table assembly that connects is located between safety filter core and paper filter element.
The beneficial effects of the utility model are: can prevent that the hydraulic oil in the fuel tank is splashed on the paper filter element, prolongs the service life of paper filter element 1..2. pressure and the atmospheric pressure balance in the assurance fuel tank.3. can clear up the grains of sand of accumulating in the empty filter easily, effectively guarantee the cleannes of fuel tank inner fluid.
Description of drawings
Fig. 1 looks cross-sectional view for master of the present utility model.
Among the figure: 1 protective acoustic cover assembly, 2 paper filter elements, the 3O RunddichtringO, 4 connect the sand table assembly, 5 safe filter cores.
The specific embodiment
As shown in Figure 1, empty filter of the present utility model is exactly to transform on the basis of common empty filter, install one additional and connect sand table assembly 4, connect 4 shutoff of sand table assembly between protective acoustic cover assembly 1 and paper filter element 2 in the cavity, connect O type circle sealing 3 is arranged between sand table assembly 4 and protective acoustic cover assembly 1, the paper filter element 2, and it is used for blocking the oil that the below oil cylinder is splashed to the sky filter on the one hand, accepts the grains of sand that the top enters on the one hand, and it can adopt multiple material.
Its erection sequence is: be installed to protective acoustic cover assembly 1 on the fuel tank earlier, tightly live with cross recessed countersunk head sscrew, then successively with rubber washer, safe filter core 5, O type circle 3, connect sand table assembly 4, paper filter element 2, rubber washer etc. and put into protective acoustic cover assembly 1, end cap and protective acoustic cover assembly 1 are tightened got final product again.
Its operation principle is: extraneous air enters in the sky filter by A mouth uniform on the protective acoustic cover assembly 1, if be mingled with the grains of sand, buffering through internal structure, the grains of sand just fall into and connect sand table assembly 4, air because of connecing 3 sealings of O type circle arranged between sand table assembly 4 and protective acoustic cover assembly 1, the paper filter element 2, so can only enter in the fuel tank from paper filter element 2; Otherwise the air in the fuel tank is discharged from the A mouth on the protective acoustic cover assembly 1 by paper filter element 2.
Claims (3)
1. an empty filter comprises protective acoustic cover assembly (1), paper filter element (2) and safe filter core (5), it is characterized in that: comprise connecing sand table assembly (4) described connecing in the horizontal cavity of shutoff between protective acoustic cover assembly (1) and paper filter element (2) of sand table assembly (4).
2. empty filter according to claim 1 is characterized in that: described connect between sand table assembly (4) and the protective acoustic cover assembly (1) and connect between sand table assembly (4) and the paper filter element (2) be equipped with O RunddichtringO (3).
3. empty filter according to claim 1 and 2 is characterized in that: the described sand table assembly (4) that connects is positioned between safe filter core (5) and the paper filter element (2) and locates.
