The utility model can solve the problems that the turbulence can not be formed, the screening efficiency is lower and the energy consumption is higher in the prior art.
Description
Technical field
The utility model relates to the pulp and paper industry machinery technical field, specifically a kind of lug blade type screening rotor that is installed in the screening installation.
Background technology
At present, the screening rotor of installing in the conventional screen optional equipment, difference is vertically to connecting a plurality of strip fins on its rotor surface, during screening installation work, rotor drives the fin rotation and produces pressure slurry is got rid of to the screen cylinder that is arranged on the rotor outside, slurry by screen cylinder is good paper pulp, and the slurry by screen cylinder then is not a tail slurry or slag slurry.Because this kind fin is whole strip, it can only make slurry form laminar flow when rotated in screening installation, and can't form turbulent flow, cause the water in the slurry to be sifted out in a large number by screen cylinder, not only making slurry concentration become big, the mobile resistance that reduces, passes through screen cylinder thus increases, directly have influence on pulping rate and screening effeciency, and increased the consumption of the energy greatly.
Summary of the invention
The purpose of this utility model provides a kind of lug blade type screening rotor, and it can solve that prior art exists can't form turbulent flow, screening effeciency is lower, energy consumption is bigger problem.
The purpose of this utility model is achieved through the following technical solutions: lug blade type screening rotor, it comprises cylindrical shell, the circumferential wall surface of cylindrical shell from top to bottom respectively layering connect several projection blades, the projection blade has at interval each other, and the projection blade is a front end with drum surface apart from high, rear end and drum surface apart from low shape.
For further realizing the purpose of this utility model, also can finish by the following technical programs: described projection blade is made up of blade, middle blade, middle blade, middle lower blade, lower blade respectively, blade, middle blade, lower blade are separately positioned on the upper, middle and lower portion on cylindrical shell circumferential wall surface, and vertically to mutual correspondence; Between blade and the middle blade middle blade is set, middle blade reaches the vertical to mutual dislocation of middle blade with blade respectively, and middle lower blade is set between middle blade and the lower blade, and middle lower blade is vertical to mutual corresponding with middle blade.Blade nock distance is downward-sloping shape greater than the lower end distance, and its upper end is an acute angle; Middle blade anteriomedial distance is acute angle greater than the two ends distance in the middle of it; Lower blade front lower ends distance is that greater than the upper end distance shape that is inclined upwardly, its lower end are acute angle; The middle and upper part of middle blade front end is an acute angle, and the middle and lower part of middle lower blade front end is an acute angle.Be respectively provided to few step on the acute angle of blade, middle blade, middle blade, middle lower blade, lower blade.
The beneficial effect that the utility model can produce: because of screening rotor circumference wall surface from top to bottom respectively layering connect several projection blades, each projection blade is evenly distributed on to be had on the surface of screening the rotor circumference wall at interval each other, to substitute traditional strip fin, the projection blade is that front end and drum surface are apart from height, rear end and the low shape of drum surface distance, the projection blade is respectively by blade, middle blade, middle blade, middle lower blade, lower blade is formed, blade, middle blade, lower blade be separately positioned on cylindrical shell circumferential wall surface on, in, the bottom, and vertically to mutual correspondence; Between blade and the middle blade middle blade is set, middle blade reaches the vertical to mutual dislocation of middle blade with blade respectively, between middle blade and the lower blade middle lower blade is set, middle lower blade is vertical to mutual corresponding with middle blade, when so the screening rotor drives its rotation, can make slurry turbulization in screening installation, make slurry mix more fully, effectively reduce the concentration of slurry with this, reduced the resistance of slurry by screen cylinder, increased the quantity of slurry, so improved screening effeciency greatly, greatly reduce energy consumption by screen cylinder;
Because of blade nock distance is downward-sloping shape greater than the lower end distance, the upper end is an acute angle; Middle blade anteriomedial distance is greater than the two ends distance, and the centre is an acute angle; Lower blade front lower ends distance is that greater than the upper end distance shape that is inclined upwardly, lower end are acute angle; Middle blade front end middle and upper part is an acute angle, and middle lower blade front end middle and lower part is an acute angle, so it can make slurry form the better effects if of turbulent flow, slurry is more fully mixed, and further prevents its excessive concentration;
Be respectively provided to few step on the acute angle because of blade, middle blade, middle blade, middle lower blade, lower blade, to form the acute angle that is step shape respectively, so it can further increase the centrifugal action of slurry, increase further that fiber can be by the quantity of screen cylinder in the slurry.
The utility model is widely used on the screening installation of pulping and paper-making industry, can produce tangible society, economic benefit.
