Abstract
The utility model provides a coarse-screening rotor and aims to optimize the structure of a rotor in paper pulp screening equipment in the prior art. The coarse-screening rotor comprises a rotary drum, a cover plate and blades arranged on the outer side of the rotary drum. The utility model is characterized in that the blades are strip-shaped, and the blades are vertically mounted along the generating line of the rotary drum; and flow guide vanes are obliquely arranged between two blades on the outer side of the rotary drum, and turbulence vanes are obliquely arranged on the inner side of the rotary drum. In the utility model, the blades play the screen plate cleaning function and the flow guide vanes play the pulp lifting function, so as to moderately screen the coarse paper pulp with high efficiency. The utility model is particularly suitable for the paper pulp with high content of large-grain foreign substances.
Description
Technical field
The utility model relates to a kind of rotor that is applicable in the paper-making pulping coarse sizing equipment, specifically a kind of scalping rotor.
Background technology
Blade in traditional pulp sifting rotor all is to have some tilting projection blades to constitute, by blade is designed to tilt or be arranged to tilt, make the blade when stirring, to realize rising the purpose of slurry.Blade provides two kinds of functions in rotor, promptly rise slurry and stirring, generally all is to generate by tilting blade.
The utility model content
The purpose of this utility model is to provide a kind of scalping rotor, and rising the slurry function has different parts to realize respectively with agitating function.
The technical scheme in the invention for solving the technical problem is: a kind of scalping rotor comprises rotating cylinder, cover plate and is arranged on the blade in the rotating cylinder outside that it is characterized in that described blade is a strip, described blade is provided with along cylinder bus vertical direction; Between two blades of the described rotating cylinder outside, be obliquely installed flow deflector.
Described rotating cylinder inboard is obliquely installed spoiler.
Connected mode between described flow deflector and the rotating cylinder is welding, and the connected mode between described spoiler and the rotating cylinder also is welding.
The beneficial effects of the utility model are: the cleaning sieve plate function of rotor and liter slurry function are realized by blade and flow deflector respectively, have realized crude pulp is provided the purpose of the screening of efficient gentleness.When increasing production capacity and screening effeciency, it is about 30%～50% to reduce spinner velocity, and the expense that cuts down the consumption of energy is about 40%, can be particularly useful for the high paper pulp of coarse impurities content up to 3% the dense operation down of slurry.
Description of drawings
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a front view of the present utility model;
Among the figure: 1 rotating cylinder, 2 cover plates, 3 blades, 4 flow deflectors, 5 spoilers.
The specific embodiment
As shown in Figure 1 and Figure 2,
A kind of scalping rotor comprises rotating cylinder 1, the cover plate 2 of stainless steel and is arranged on the blade 3 in the rotating cylinder outside.Rotating cylinder 1 is installed in by transition apparatus on the main shaft of driving mechanism, and cover plate 2 is arranged on the end face of rotating cylinder.Blade is a strip, and blade 3 is along the welding of rotating cylinder 1 bus vertical direction, and blade is a multi-disc, and the uniform rotating cylinder external circumferential that is arranged in forms array of vanes.Welding flow deflector 4 tilts between two blades of rotating cylinder 1 outside, flow deflector is a multi-disc, the uniform rotating cylinder external circumferential that is arranged in, form the flow deflector array, flow deflector 4 and rotating drum shaft are to angled welding, can help slurry to break away from the screening zone as early as possible, be unlikely to produce concentration phenomena, improve effective sieve area.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
