Because the disc structure is light, argon arc welding is needed when welding the outer circle of the disc, plasma welding can be adopted for the traditional disc, the argon arc welding has the advantage of small heat compared with the plasma welding, and the plasma welding can damage the sintering felt and destroy the integrity of the disc.
Furthermore, the isolation support comprises a support ring and a plurality of support rods which are arranged in an array mode in the circumferential direction of the support ring and are arranged in a radial mode, the size of the support ring is consistent with that of the edge-covering part, the isolation effect can be achieved, the inner ring of the disc can also serve as a sealing gasket, the isolation support and the disc are in a separated structural design, and the disc is convenient to clean after being used.
Furthermore, the inner edge covering structure is U-shaped at the inner side of the disc and respectively covers the end parts of the sintering felts at the two sides of the lining net, and the edge covering part and the sintering felts are pressed together by a special die.
Furthermore, the screen frame comprises a plurality of concentric rings, each filter is arranged in an array along the circumferential direction of each ring to form a plurality of annular filter groups, and the filters on two adjacent filter groups are arranged in a staggered mode in sequence, so that the flow resistance among the filter channels is reduced.
Furthermore, the filters are integrally rectangular, so that a filtrate channel formed among the filters is dovetail-shaped, the flow resistance is reduced, and the flow capacity is improved.
The invention has the technical effects that the three-dimensional formed lining net structure has large circulation and can deal with the filter medium with high viscosity; the weight of the filter disc is reduced; the thickness of the filter disc is reduced; compared with the traditional discs with heavy mass and large thickness, more discs can be arranged in the filter, so that the filtering area is effectively increased; the medium channel has no dead angle, a perfect structure close to no resistance can be achieved, and the service cycle of the disc is prolonged; the separation type structure design of the isolation bracket and the disc ensures that the disc is convenient to clean after being used.
