And existing mylar filter element forms cylindrical shape jointly by multilayer planar formula screen pack, welding hexagon termination, one end, other end welding screwed pipe forms integral filtering element, and screen pack is non-dismountable, as shown in Figure 1.Existing filter is fixed on base plate by non-removable integral filtering element by its lower end screw thread, on base plate, uniform welding has column, the upper end of integral filtering element is coated with upper cover plate, and upper cover plate is provided with through hole and pillar hole, is fixedly connected with between upper cover plate and base plate by column.If screen pack remains a large amount of impurity, affect filtering accuracy, integral filtering element is just needed all to change, such replacing options causes the waste of material to a great extent, add scrap build cost, and the order time that filter core integral replacing needs is long, operating efficiency is low especially; Meanwhile, exoskeletal stay pipe in existing this mylar filter element, withstand voltage, shock-resistant ability, be very easily out of shape, service life is short; In addition, the screen pack of existing this mylar filter element is plane formula, and filter area is little, and retaining power is poor, and filtering accuracy is not high, affects resin quality.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provides a kind of filter core for mylar filter.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of filter core for mylar filter, and its special character is, comprises filtration net cover and filter tube, and it is inner that described filter tube is sleeved on described filtration net cover; Described filter tube top is welded with cylindrical projection, and the bottom periphery of described cylindrical projection is provided with external screw thread, and described filter tube bottom is welded with sealed groove; Described filter tube top closure, bottom end opening; The upper and lower two ends of described filtration net cover are welded with sealed circular ring respectively, and the sealed circular ring of described filtration net cover lower end is connected in the sealed groove of described filter tube bottom; Described filtration net cover has the fold of a series of interior connection, described fold have in succession, the fold that forms filtration net cover one external boundary is most advanced and sophisticated; Described filtration net cover and filter tube are fixed by fit sealing lid, and described fit sealing covers and is provided with screwed hole, and the internal thread of described screwed hole matches with the external screw thread bottom described cylindrical projection.
The beneficial effects of the utility model are:
1, stainless steel filter tube of the present utility model provides skeletal support for whole filter core, makes filter core not yielding, increases the service life, and also greatly improves high temperature resistant, the high pressure resistant and impact resistance of filter core.
2, filter tube of the present utility model is sleeved on filtration net cover inside, and dismounting and change is convenient, saves material.
3, filtration net cover of the present utility model is formed by multiple filtration net folding, surface is divergence expression crimp design, compared with plane formula screen pack, " triangle " crimp design be folded into can improve self stability, intensity and shock-resistant ability, not yielding, save stainless steel strip skeleton and the in-built firm annulus of filter screen that existing flat filter welds on the net, and add filter area, improve retaining power and filtering accuracy.
4, the utility model well solves the waste of material problem changed monolithic filter filter core and cause, and has saved financial cost, has shortened integral filter core ordering cycle, greatly increase work efficiency.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described filter tube is stainless steel.
The beneficial effect of above-mentioned further scheme is adopted to be improve withstand voltage, the shock-resistant ability of filter core, not yielding, long service life.
Further, outside the lower end of described sealed groove, described filter tube, positioning threads is arranged with.
The beneficial effect of above-mentioned further scheme is adopted to be arranged on the base plate of filter by screw thread by filter core, play fixation.
Further, the aperture of described filter tube is 6mm.
Further, described filtration net cover is formed by multiple filtration net folding.
The beneficial effect of above-mentioned further scheme is adopted to be that multiple filtration net folding can strengthen the intensity of filtration net cover self, not yielding.The filter tube larger with intensity coordinates, and more can improve withstand voltage, the impact-resistant ability of filter core, increase the service life.
Further, described filtration net cover is formed by three layer filtration net folding, and three layer filtration net is followed successively by 30 orders, 200 orders and 30 orders by aperture outside to inside.
The beneficial effect of above-mentioned further scheme is adopted to be that two-layer screen pack inside and outside, as catch net, can play firm support to filtration net cover itself, carries out available protecting to the filtration working net of centre simultaneously.
