Abstract
The utility model discloses a filter core for an air filter. The filter core is characterized by comprising a filter core upper cover (2) arranged on the upper part of the filter core and a filter core lower cover (1) arranged on the lower part of the filter core, wherein a filter screen (4) for filtering and a filter core framework (3) for supporting are arranged between the filter core cupper cover (2) and the filter core lower cover (1); and the periphery of the filter core lower cover (1) is provided with an oil blocking groove (5). The filter core for the air filter has a simple and practical structure, high sealing performance and novel and attractive appearance; and the oil blocking groove on the filter core can be used for preventing oil mist and oil drops from leaking, so that the oil mist and the oil drops can be recycled during air filtering.
Description
Technical field
The utility model relates to the air cleaner cartridge that uses in the hydraulic system.
Background technology
At present, the air cleaner cartridge that hydraulic system is used at work, only play the effect of filtered air, to since in the hydraulic system mist of oil and the oil droplet that produce can't collect, cause mist of oil and oil droplet to leak outside and spatter outward, not only causing the fuel tank outer surface all is greasy dirt and leakage, and also environment and fuel tank internal pollute to external world.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, reclaim mist of oil and oil droplet, airfiltering air cleaner cartridge.
The technical solution adopted in the utility model is as follows:
A kind of air cleaner cartridge, it is characterized in that it comprises filter core loam cake that is positioned at filter core top and the filter core lower cover that is positioned at the filter core bottom, be provided with the filter screen and the passive frame of filter element of filtration between filter core loam cake and filter core lower cover, the periphery of described filter core lower cover is provided with the retaining oil groove.
Adopt glue bond to fix between described filter core loam cake, filter core lower cover and filter screen and the frame of filter element, filter core is become one.
Described filter core loam cake and filter core lower cover adopt black oil resistant butadiene-acrylonitrile elastomeric material to make, and energy oil resistant, gas have excellent sealing performance.
The beneficial effects of the utility model have:
Simple and practical, good seal performance, the outward appearance novel and beautiful, the retaining oil groove on the filter core can make the pollution that can not leak outside of mist of oil and oil droplet, can also play the effect of reclaiming mist of oil and oil droplet in the airfiltering while.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model generally is installed in air filter inside, it comprises filter core loam cake 2 that is positioned at filter core top and the filter core lower cover 1 that is positioned at the filter core bottom, the outer retaining oil groove 5 that is with at filter core lower cover 1 filter core, between filter core loam cake 2 and filter core lower cover 1 filter screen 4 and the passive frame of filter element 3 of filtration, adopt glue bond to fix between filter core loam cake 2 and filter core lower cover 1 and filter screen 4 and the frame of filter element 3, filter core is become one.
The course of work of the present utility model is as follows:
In the hydraulic work system process, temperature constantly raises, forming the gentle mixture of oil in fuel tank is mist of oil, variation up and down with the fuel tank internal pasta, mist of oil passes through from the filter core of air filter, stopped by filter screen on the filter core 4 and frame of filter element 3, cooling back mist of oil separates, oil is stayed on the filter screen 4, air, forms oil droplet and flows down along filter screen 4 after the oil on the filter screen 4 runs up to a certain degree smoothly by filter screen 4, because the periphery of filter core lower cover 1 has retaining oil groove 5, oil droplet is got back to the inboard of filter core, gets back to fuel tank internal, realizes the recycling of mist of oil and oil droplet.
Other undeclared part that the utility model relates to is same as the prior art.
