Abstract
The invention belongs to a sort of stick drum that has circle preload stress, referring to the amelioration of important equipment pressure sieve technique in the papermaking pulping process. It comprising upper flange, nether flange, stick and seal ring, the stick embedding in the locating slot of grooved seal ring, forming sifting gap between sticks, the embedded part of stick forming head (or glue joint) by rivet to fix the stick, glue joining with circle prestress by glue outside the head, conjoined the dispersed head of the same fixed ring, consequently increasing the fixed reliability of stick, embedding stiffening ring in the hatch of grooved seal ring according to needs, the two ends of stick separately joining with the upper and nether flange. So the stick and seal ring do not need welded fastening, conquering the disadvantageous influence of weld, at the same time improving the anti-stress and fatigue resistance ability of screen cylinder, improving accuracy of manufacture and prolonging life duration. Because glue joining the head (or embedded part) of the same grooved lining retainer ring to integer by circle prestress, and part glue liquid entering the gap of locating slot, all increasing the fixed reliability of stick.
Description
Technical field
The invention belongs to a kind of rod drum that has shrink ring, relate to the improvement of the visual plant pressurized screen technology in the paper-making pulping process.
Background technology
Pressurized screen is the visual plant in paper industry papermaking and the pulping process, and wherein screen cylinder is again crucial consumable accessory.The cylindrical shape screen cylinder in use bears system pressure, and the rotation of rotor makes screen cylinder bear outwards (extruding) and inside (absorption) periodically variable load again, requires screen cylinder tension stress and anti-fatigue performance good in the use.
Bar-shaped slotted screen drum is the regeneration product of milling screen cylinder, and on the market bar-shaped slotted screen drum rod and retainer ring adopt welding method to fix, because welding stress is big, easily produce distortion, crackle etc., cause screen cylinder gap inequality, rod initial failure form such as come off causes screen cylinder to be scrapped.External existing pulp-screening device, patent of invention as application number 96180453.x, though with rammer riveting rod (filter screen silk) base portion (or in base portion spot welding) rod (filter screen silk) being fixed on flute profile props up in the backing member, but because of heading (or base portion weld) props up in the backing member in same flute profile is self-existent, also easily produces rod (filter screen silk) in the use and comes off.The same negative effect that has welding of base portion welding.
Summary of the invention
Purpose of the present invention: be that a kind of new rod drum structure will be provided, change assembly method, avoid the negative effect of welding, overcome the drawback that rod comes off simultaneously.
Technical scheme of the present invention is: upper flange, lower flange, rod and sealing ring are drawn together in excellent bulge, rod embeds in the locating slot of grooved retainer ring, make and form the screening slit between the rod, the rod Embedded Division forms heading (or splicing) through the rammer riveting rod is fixed, heading external application glue in the flute profile retainer ring glueds joint mutually with shrink ring, the heading of each dispersion is fused, can be embedded with reinforcing ring as required at the opening part of grooved retainer ring, the two ends of rod join with upper flange, lower flange respectively.
Advantage of the present invention is: it is fixing that the present invention need not weld rod and retainer ring, overcome the adverse effect of welding.Improved the anti-Zhang Nengli and the anti-fatigue ability of screen cylinder, improved the accuracy of manufacture and increased the service life.Because heading (or Embedded Division) splicing of same flute profile being propped up in the lining retainer ring by shrink ring is linked to be integral body, the part glue also enters in the slot of location simultaneously, has all increased the rod reliability of fixation again.
Description of drawings
Accompanying drawing 1 is a rod drum structure cutaway view;
Accompanying drawing 2 is the detail drawings of I in the accompanying drawing 1.
Among the figure: 1-upper flange, 2-lower flange, 3-sealing ring, 4-rod, 5-grooved retainer ring, 6-heading, 7-shrink ring, 8-reinforcing ring, 9-glue.
The specific embodiment
1,2 couples of the present invention are described in further details below in conjunction with accompanying drawing.A kind of rod drum that has shrink ring, it comprises upper flange 1, lower flange 2, rod 4 and sealing ring 3, form the screening slit in the locating slot of rod 4 embedding grooved retainer rings 5, rod 4 Embedded Divisions form heading 6 (or splicing) with rod 4 location through the rammer riveting, glued joint mutually with shrink ring 7 at heading 6 external application glue 9, each heading 6 that disperses in the same flute profile retainer ring 5 is fused, opening part at grooved retainer ring 5 can be embedded with reinforcing ring 8 as required, and the two ends of rod 4 join with upper and lower flange respectively.
Glued joint among the present invention with glue to be that high strength structural adhesion 9 should have water-fast, chemical-resistant stability, corrosion-resistant, ageing resistance good, heatproof is not less than 180 ℃, shearing strength 〉=15Mpa after solidifying, shrink ring 7 adopts stainless steel flat filament or round steel wire or other load materials, can be a circle or a multi-turn, also can form one with reinforcing ring 8, prestressing force can apply by mechanical means, and reinforcing ring 8 is finished shrink ring 7 splicing back installations.Other parts are except that sealing ring 3, and material adopts the material of SUS316L or SUS304 stainless steel or similar performance to make.
Claims (3)
