The present invention is owing to having adopted above technical scheme, have significant technique effect: the present invention is by being combined with each other the different filtration panels of pore size and filtration main board, thereby making in filter process to be not easy stops up, and the resistance filtered also reduces greatly, reduce because cross-head pressure makes the advantages such as filter distortion.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Fig. 2 is the I section enlarged drawing in Fig. 1.
Fig. 3 is the left view of Fig. 1.
The toponym that in above accompanying drawing, each number designation refers to is as follows: 1-filtration panels, 2-filtration main board, 11-inferior filter bores, 21-main filter bores wherein.
The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment, the present invention is described in further detail:
Extruder filters and uses the various metals composite plate, as shown in Figure 1 to Figure 3, comprises filtration panels 1 and filters main board 2, and described filtration panels 1 is provided with time filter bores 11, filters main board 2 and is provided with main filter bores 21, and filtering main board 2 is metallic plate.Existing filter is monolithic, due to the restriction that is subject to processing condition, the aperture of filter bores is all more than 0.8mm, and the present invention is combined with each other by will and filtering main board with different pore size size filtration panels, in the structural strength that guarantees filter, make in filter process to be not easy to stop up, and the resistance filtered also reduces greatly, reduce because cross-head pressure makes the defect of filter distortion.
The thickness that filters main board 2 is 7-10mm, and the diameter of main filter bores 21 is 1.5-3mm.The thickness of filtration panels 1 is 1-3mm, and the diameter of inferior filter bores 11 is 0.01-0.5mm.
Extruder filters by various metals composite plate manufacture craft, comprises the following steps:
A, get the metallic plate that 7-10mm is thick, obtain filtering main board 2 after getting out main filter bores 21 by numerical control drilling machine; Get the metallic plate that 1-3mm is thick, by after laser boring machining time filter bores 11, obtaining filtration panels 1;
B, filtration main board 2 are composited with filtration panels 1 use energy storage type butt-welding machine.
Filter main board 2 apertures larger, therefore adopt numerical control drilling machine boring; Filtration panels 1 is by the laser boring machined, and the diameter of the inferior filter bores 11 of producing is 0.01-0.5mm.By double face slab and double-deck through hole, can effectively improve filter effect.
Filtering main board 2 is SKD61 or 38CrMoAlA hot die steel; Filtration panels 1 is wolfram steel or white steel or high-speed steel.Filtering main board 2 can be SKD61 or 38CrMoAlA and other heat treated special steels, and filtration panels 1 can be wolfram steel or white steel or high-speed steel and other heat treated special steels, its surfacing, and sturdy and durable, long service life, can adapt to more place.
