Abstract
The utility model provides a double-layer filter. The double-layer filter comprises a shell and a filter material, wherein the filter material is arranged in the shell. The double-layer filter is characterized in that the filter material comprises two layers, a support framework is arranged at the inner part of the filter material, a rough filtration material is installed outside the support framework, and a second-layer support framework is installed at the periphery of the rough filtration material, a refined filtration material is installed outside the second-layer support framework, and an interval of the rough filtration material is larger than that of the refined filtration material. When the double-layer filter is in use, large particles in liquids or gases can be filtered and removed by the rough filtration materials of the filter, and small particles are filtered by the refined filter material, so that the high filter precision is achieved while the service life is not affected.
Description
Technical field
The utility model relates to filter, is specifically related to a kind of bilayer filter.
Background technology
Filter has only one deck now, and filter material can't reach long-life and high-precision requirement.
The utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of bilayer filter.
Concrete technical scheme is following:
A kind of bilayer filter comprises shell and filter material, and filter material is installed in the enclosure; It is characterized in that: said filter material comprises two-layer, an inner circle support frame, and support frame is outward the coarse filtration filter material; Coarse filtration filter material periphery is installed second layer support frame again, and second layer support frame is installed smart filter filter material outward; Coarse filtration filter material gap is greater than the essence filter material.
Beneficial effect:
The bilayer filter of the utility model in use, but filters little particle by essence filter filter material behind the big particle in the outer coarse filtration filter material filtering liquid of filter or the gas, when not influencing the life-span, reaches higher filtering accuracy.
Description of drawings
Fig. 1 is the utility model bilayer filter filter medium structure sketch map.
Among the figure: 1-support frame, 2-support frame, 3-second layer support frame, the smart filter of 4-filter material.
The specific embodiment
In conjunction with accompanying drawing the utility model is done and to be further described.
A kind of bilayer filter comprises shell and filter material, and filter material is installed in the enclosure; Said filter material comprises two-layer, and an inner circle support frame 1 is a coarse filtration filter material 2 outside the support frame 1; Coarse filtration filter material 2 peripheries are installed second layer support frame 3 again, the second layer support frame 3 outer essence filter filter materials 4 of installing; Coarse filtration filter material 2 gaps are greater than essence filter filter material 4.
At last, it is also to be noted that what more than enumerate only is the practical implementation example of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought the protection domain of the utility model.
