Abstract
A screen drum is used for solving the problem that existing screen drums are easy to be blocked. The screen drum comprises a screen cylinder, and filter slits are uniformly distributed on the screen cylinder circumferentially along the generatrix direction. The screen drum is characterized in that each filter slit is a continuous slotted hole from top to down, a triangular projection and a flat bottom are respectively formed on two sides of each slotted hole on the inner side of the screen cylinder when in observation from the cross section of a screen, and increased trapezoidal opening is arranged on the periphery of each slotted hole on the outer side of screen cylinder. The screen drum produces micro-turbulence which is strong enough through proper corrugated angles, thereby preventing fibers netting on the surface of the screen cylinder. The flat bottoms elongates route of the micro-turbulence to weaken the micro-turbulence so as to prevent deformable adhesive substances from deforming to pass through the screen cylinder.
Description
Technical field
The utility model relates to the screen cylinder in a kind of pulp sifting machine, the higher screen cylinder of specifically a kind of filter efficiency.
Background technology
In the existing pulp sifting equipment the agent structure of screen cylinder all be one and have the tubular that filters the slit that offer the ripple that the height of triangle rises and falls in the inboard of filtering the slit, the turbulence effect when being used to improve work increases filter efficiency.Wherein, the quality of corrugated design has directly determined the height of screen cylinder operating efficiency.
The utility model content
The purpose of this utility model is in order to improve screening effeciency, cuts down the consumption of energy and a kind of screen cylinder of designing, its advantage is the screening effeciency height, fiber loss is few, power consumption is low, long service life, be difficult for sticking with paste sieve, stock quality is good.
The technical scheme in the invention for solving the technical problem is: a kind of screen cylinder, it comprises that the upper and lower port place is provided with the screen drum of flange, described screen drum circumferentially is evenly equipped with the filtration slit of offering along generatrix direction, it is characterized in that, described filtration slit is a continuous from top to bottom strip hole, on the screen drum cross section, observe, described screen drum inboard is respectively denation and flat along the strip hole both sides, described denation and flatly show as corresponding strip hole arrange at interval successively on inboard wall of riddle drum; The described screen drum outside is the trapezoid-shaped openings that increases gradually along the strip hole periphery.
Described screen drum outside above-below direction has been welded with the reinforcing ring muscle of reinforced structure effect.
The beneficial effects of the utility model are: suitable ripple angle make to produce enough strong microturbulence, prevents that fiber from knotting on the screen drum surface.Wherein, flat place has elongated the route of microturbulence, and microturbulence is weakened, and passes through screen drum to prevent yielding gluing thing from changing profile.
This flat screen drum structural design alternate with the triangle ripple increased the actual percent opening of screen cylinder under running status, can obtain bigger throughput, improved screening effeciency greatly, and this structure can higher concentration (5%) down operation can not block up sieve, be particularly useful for the screening of high concentration paper pulp.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the sectional deployed condition in A-A place among Fig. 1;
Fig. 3～Fig. 4 filters the corrugated at place, slit for existing screen drum;
Among the figure: 1 screen drum, 2 upper flanges, 3 lower flanges, 4 strip holes, 5 reinforcing ring muscle, 6 denations, 7 is flat, 8 trapezoid-shaped openings.
The specific embodiment
Shown in Fig. 1～2,
A kind of screen cylinder, main body are the screen drum 1 of a stainless steel, and the upper and lower side of screen drum welds upper flange 2 and lower flange 3 respectively, and flange is used for installing.Screen drum circumferentially is evenly equipped with the filtration slit of offering along generatrix direction, and this filters slit is a continuous from top to bottom strip hole 4, and the mode by milling processes.For increasing the bulk strength of screen drum, above-below direction has been welded with the reinforcing ring muscle 5 of reinforced structure effect outside screen drum, and the reinforcing ring muscle is circular corrosion resistant plate, is fixed on the screen drum by the mode of welding.
Observe on the screen cloth cross section, described screen drum inboard is respectively denation 6 and flat 7 along the strip hole both sides, and denation and flatly show as corresponding strip hole arrange at interval successively on inboard wall of riddle drum forms the corrugated that height rises and falls.The screen drum outside is the trapezoid-shaped openings 8 that increases gradually along the strip hole periphery, and usefulness is added to the mobile performance of the slurry after the screening.In working order down, denation makes fluid produce enough strong microturbulence, prevent that fiber from knotting on the screen drum surface, and flat place has elongated the route of microturbulence, and microturbulence is weakened, and passes through screen drum 1 to prevent yielding gluing thing from changing profile.
The utility model is optimized the streamline of slurry and the Energy distribution of screen cylinder working face by optimizing the size of denation, flat, strip hole, can obtain better effect.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (2)
1. screen cylinder, it comprises that the upper and lower port place is provided with the screen drum of flange, described screen drum circumferentially is evenly equipped with the filtration slit of offering along generatrix direction, it is characterized in that, described filtration slit is a continuous from top to bottom strip hole, observe on the screen drum cross section, described screen drum inboard is respectively denation and flat along the strip hole both sides; The described screen drum outside is the trapezoid-shaped openings that increases gradually along the strip hole periphery.
2. a kind of screen cylinder according to claim 1 is characterized in that, described screen drum outside above-below direction has been welded with the reinforcing ring muscle of reinforced structure effect.
