Description

Low-resistance high-strength filtering support structure

Technical Field

The utility model relates to a filter core bearing structure technical field especially relates to the filtration bearing structure of low resistance high strength.

Background

The filter core filter material is usually regarded as to current filter core supporting mesh, provides bearing structure for the filter core, and it has porous confession fluid to pass through to open simultaneously, and the trompil that sets up on the current supporting mesh is simple planar structure, and when fluid flowed into the trompil, at the trompil edge formation vortex, the resistance is great, for the resistance that reduces the supporting mesh, and usual way is to increase hole quantity or area, and this kind of way has also reduced the intensity of support when reducing the resistance.

Therefore, a new support structure needs to be designed to reduce the resistance while ensuring the strength.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a filtration bearing structure of low resistance high strength solves the problem that the intensity that current supporting network caused reduces for reducing the resistance.

Its technical scheme is, filtration bearing structure of low resistivity high strength, including the supporting network, the supporting network surface sets up a plurality of trompils, each the trompil edge is bent along the liquid flow direction and is formed curved transition structure, and when the fluid passes through from the trompil, under curved transition structure effect, the vortex is eliminated, under the prerequisite that does not change original trompil quantity and trompil area, guarantee the supporting network intensity, the resistance is reduced.

Furthermore, the trompil is divided into a plurality of trompil units on the supporting network according to the sequence of arranging, and single trompil unit includes a row of trompil and two rows of trompils of arranging along the vertical direction of supporting network, each on a row of trompil and two rows of trompils the trompil is arranged and is staggered each other along vertical direction array, each the trompil unit is arranged along the supporting network periphery array, and keep the interval, avoid on the different trompil units trompil distance too close, influence supporting network intensity, this kind of trompil structural design, effective area on the ability make full use of supporting network, under the wall body of assurance intensity, increase trompil quantity as much as possible, realize better resistance effect that falls.

The utility model has the technical effects that a transition structure with the function of guiding flow and reducing resistance is added on the basis of the original hole, and the structure can effectively reduce the eddy generated around the hole when the fluid passes through the hole, thereby achieving the purpose of reducing resistance and ensuring the structure of the supporting net; the design of the optimized perforated structure is better than that of the original supporting net structure, and the better resistance reducing effect is realized.
