Improve as one of the present utility model, the circular slab that described stainless steel shrouding adopts corrosion resistant plate blanking to be processed into, inside offers through hole, and offers the groove of 2.5 × 45 ° in the side of stainless steel shrouding, so that weld assembled, opposite side offers two circular grooves.
Improve as one of the present utility model, be provided with O RunddichtringO in described circular groove, for sealing, preventing unfiltered cooling water from entering in filter screen from filter screen bottom affects filter effect.
Improve as one of the present utility model, described filter screen is the double-layer stainless steel filter screen adopting stainless steel material to make, and effectively raises filtering accuracy.
Improve as one of the present utility model, the order number scope of described double-layer stainless steel filter screen is at 40 ~ 90 orders, and the specification preferably adopted is every square feet of 50 orders, and its filtering accuracy is moderate.
Improve as one of the present utility model, the through-hole aperture on described stainless steel shrouding and the internal diameter of described inner sleeve are consistent, and preferably, both are Φ 34.
Improve as one of the present utility model, described overcoat all adopts argon arc welding to weld with each pad between inner sleeve and between overcoat with stainless steel shrouding.
Relative to prior art, the filter core overall construction design that the utility model proposes is ingenious, is fixed by filter screen by overcoat and inner sleeve, and bottom filter core, adopts the shutoff of stainless steel shrouding and welding, improves the overall resistance to pressure of filter core; Change filter screen into bilayer by original individual layer, make the filtering accuracy of filter core turn improve 25% on original basis; Because filter core entirety all adopts stainless steel, thus invar iron rust can be avoided to lose and the water quality of impact filtration cooling water; That this filter core has simple and reliable for structure, easy to process, low cost of manufacture, use is changed is convenient, long service life and be convenient to advantages such as depositing, is easy to promote the use of.
