Abstract
A spiral dual-embedded screen cylinder comprises a spiral rod, an external fixed ring, an internal fixed ring, a reinforced ring, an upper flange, a lower flange and a sealing ring; the spiral dual-embedded screen cylinder is characterized in that the spiral rod is embedded and positioned simultaneously by the external fixed ring and the internal fixed ring; the external fixed ring is a U-shaped material and the internal fixed ring is a flat bar; the external fixed ring is connected with the reinforced ring; two ends of the spiral rod are connected with the upper flange and the lower flange respectively; and the sealing ring is embedded on the lower flange. The screen cylinder and the manufacture method thereof have the advantages that as the spiral aperture is longer than the straight aperture, the screening aperture ratio is increased; as the spiral aperture leads the upstream type rod cylinder paper pulp easy to arise, the impurities are easy to be removed and not easy to block the screen seam or be thickened; the rotor resistance is reduced, the energy consumption is reduced and the productivity is improved; and the method for obtaining the spiral dual-embedded fixed rod by extending the sieve plate and rolling for forming is reliable and easy, the aperture precision is high and the stability is good.
Description
Technical field
The present invention relates to the excellent screen cylinder of a kind of paper-making pulping, relate in particular to a kind of spiral dual-embedded screen cylinder and manufacture method thereof.
Background technology
Pressurized screen is the visual plant of paper industry, wherein screen cylinder is critical component, also consumable accessory simultaneously, the excellent screen cylinder sieve of tradition seam is for arranged in a straight line, advance under paper pulp in screening process, when going out on impurity (bits), because revolving second, sieve seam and rotor drive that to be spiralling paper pulp direction inconsistent, the deslagging resistance is strengthened, the easy dehydration of paper pulp accommodating, concentration increases, easily the blocking screen seam reduces production efficiency, energy consumption increases, and it is high that when serious, easy large tracts of land seals the interior voltage rise of sieve seam (envelope cylinder) result, and the rod drum is destroyed.
Summary of the invention
The object of the present invention is to provide a kind of spiral dual-embedded screen cylinder and manufacture method thereof, the gap of its screen cylinder has lead angle and coincide with the screening paper pulp flow direction, reaches purpose energy-conservation, that lower consumption, increase production.
The present invention is achieved like this, it comprises spiral rod, outer retainer ring, interior retainer ring, reinforcing ring, upper flange, lower flange, sealing ring, it is characterized in that the spiral rod lived the location by the embedding simultaneously of outer retainer ring, interior retainer ring, outer retainer ring is U-shaped material, interior retainer ring is flat, outer retainer ring connection reinforcement ring, spiral rod two ends are connected with upper and lower flange respectively, embedding sealing circle on lower flange.
Manufacture method of the present invention is that inside and outside retainer ring is to be under the vertical bar state in expansion, and Dou cuts out the rod holddown groove in groups, and the line of holddown groove has the Dou angle, after being inserted, rod forms the rhombus sieve plate, then roll to shape to cylindric, make rod form helical angle, then docking, shaping.
Advantage of the present invention is: because spiral slit is longer than straight slot, increased the screening percent opening, easily risen because there is paper pulp in spiral slit, impurity is easily got rid of and is difficult for the blocking screen seam, is difficult for enrichment, and the rotor resistance reduces, Energy Intensity Reduction, and production capacity promotes; Adopt the expansion sieve plate to roll to shape, obtain the method that helical form and two build-ins are decided rod, reliably easily go, the gap precision is high, good stability.

Fig. 1 is the spiral dual-embedded excellent screen cylinder structural representation of the present invention.
Fig. 2 is sieve basket expanded view of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, the present invention is achieved like this, it comprises rod 1, outer retainer ring 2, interior retainer ring 3, reinforcing ring 4, upper flange 5, lower flange 6, sealing ring 7, it is characterized in that rod 1 lived the location by 3 embeddings simultaneously of outer retainer ring 2, interior retainer ring, outer retainer ring 2 is U-shaped material, and interior retainer ring 3 is flat, outer retainer ring connection reinforcement ring 4, roll up curved shaping, rod 1 two ends are connected with upper and lower flange 5,6 respectively, embedding sealing circle 7 on lower flange 6.Its manufacture method is: inside and outside retainer ring is that Dou cuts out rod 1 holddown groove launching to be under the vertical bar state in groups, the line of holddown groove has the Dou angle, after being inserted inside and outside retainer ring locating slot, rod 1 forms the rhombus sieve plate, then roll to shape to cylindric, make rod form helical angle, then docking, shaping.
Claims (1)
