Description

Filter element with improved filtering area structure

Technical Field

The utility model relates to a filter core, specially adapted hydraulic pressure filters the field, uses when filtering great flow hydraulic system working medium.

Background

At present, a filter element structure commonly used by hydraulic systems at home and abroad is a corrugated filter element structure, and the filter element has the characteristics of short processing period, large filtering area, long service life and the like. The filter element belongs to a consumable hydraulic element and cannot be reused. In order to meet the requirement of normal work of a hydraulic system, the filter element is required to be replaced in time after being blocked. Therefore, the service life of the filter element directly affects the maintenance cycle of the hydraulic system. The factors influencing the service life of the filter element mainly comprise: the pollution degree of the working medium of the hydraulic system and the filtering area of the filter element. The degree of contamination of the hydraulic system working medium is determined by the characteristics of the hydraulic system itself. A high filter area construction of the filter cartridge is needed to reduce maintenance cycles of the hydraulic system.

Disclosure of Invention

The utility model aims to provide an increase the pollutant carrying capacity of filter core, extension filter core life's a filter core that improves the filter area structure.

The utility model discloses a task is accomplished like this, its characterized in that: the filter core includes the exoskeleton, the inner frame, the exoskeleton provides the support for the outer filtering layer along lateral wall drilling, and the outer filtering layer comprises the filter media and is the corrugate and form along the axial commissure, has place the inner frame in the hole of exoskeleton, the inner frame provides the support for the inner filtering layer along lateral wall drilling, exoskeleton upper end surface mounting is fixed with the upper end cover, and just a lower end cover of exoskeleton and inner frame lower extreme surface sharing is connected fixedly, the inner filtering layer comprises the filter media and is the corrugate and form along the axial commissure. The upper end cover, the outer framework and the outer filter layer are fixedly connected through high-temperature glue and are bonded together through curing. The inner framework, the inner filtering layer and the inner end cover are connected and fixed together through high-temperature glue and solidification. The high-temperature adhesive is epoxy resin high-temperature adhesive. The filter material comprises glass fiber paper and stainless steel net, and the 2/1 department of outer filter layer hole has placed interior filter layer. The outer framework and the inner framework are made of stainless steel tubes.

The utility model discloses has following effect: this technical scheme enables the filter core and has bigger filter area under the same installation space, and then increases the pollutant carrying capacity of filter core, reduces the flow resistance, prolongs filter core life simultaneously, reduces hydraulic system's maintenance cost.

Description of the drawings: fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a cross-sectional view of FIG. 1; fig. 3 is a schematic view of the installation of fig. 1.

Description of the drawings: 1. the filter comprises an upper end cover, 2, an outer framework, 3, an outer filter layer, 4, an inner end cover, 5, an inner framework, 6, an inner filter layer, 7 and a lower end cover.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The concrete embodiment is as shown in fig. 1 and 2, the filter core includes outer skeleton, the inner frame, outer skeleton 2 provides the support for outer filtering layer 3 along the lateral wall drilling, and outer filtering layer 3 constitutes by the filter media and is the corrugate and form along the axial commissure, has place inner frame 5 in the hole of outer skeleton, inner frame is followed the lateral wall drilling and is provided the support for inner filtering layer 6, and inner filtering layer filter media material is the same with outer filtering layer, outer skeleton upper end surface mounting is fixed with upper end cover 2, and outer skeleton and inner frame lower extreme surface sharing a lower end cover 7 connect fixedly, inner filtering layer constitutes corrugate along the axial commissure by the filter media and constitutes.

The upper end cover 1, the outer framework 2 and the outer filtering layer 3 are fixedly connected through high-temperature glue and are bonded together through curing.

The inner end cover 4, the inner framework 5 and the inner filtering layer 6 are fixedly connected together through high-temperature glue bonding and solidification bonding.

The high-temperature adhesive is epoxy resin high-temperature adhesive which has high shear strength and high use temperature.

The outer framework and the inner framework are made of stainless steel tubes.

The filter material comprises glass fiber paper and stainless steel net, and the discharge capacity is strong, and the pollutant carrying capacity is big, and the inner filter layer has been placed to the 2/1 department of outer filter layer hole.

And the upper end cover, the inner end cover and the lower end cover are anodized by adopting the aviation aluminum alloy surface.

Because the lower ends of the outer framework, the outer filtering layer, the inner framework and the inner filtering layer are fixed by one lower end cover, the mounting space is reduced, the filtering area is increased, and the 1/5 filtering area is increased compared with the prior art.

In conclusion, the technical scheme overcomes the defects of small filtering area, short service life and the like in the prior art by the inner and outer filtering layers 6 and 3, the inner and outer frameworks 5 and 2, the upper end cover 1 and the lower end cover 7.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
