Description
Technical field
The present invention relates to a kind of scalping, belong to paper-making pulping special equipment field.
Background technology
In papermaking pulping system, screening slagging-off link is most important, and the screening degree direct influence of slurry to the quality of paper, and then has influence on production efficiency and the profit of enterprise.At the screening stage of various waste paper pulp, the unrivaled works fine performance that pressurized screen has due to himself and reliable, become the first-selected screening installation of increasing client.
Scalping is placed in the conventional screening installation before fine screen and net fore worker in pulping system, is used for removing impurity larger in paper pulp, as a scrap of paper, plastic sheet etc.The scalping of present domestic production adopts single screen cylinder, housing to be the design of cylinder-like structure mostly, in use find that such scalping screening effect is poor, energy consumption is large, screening concentration is low, production efficiency is low, have a long way to go compared with same kind of products at abroad.Market competition more and more strong and user, paper is required to the today of day by day improving, be more and more difficult to meet the accreditation of client to this kind equipment.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of compact conformation reasonable, operate steadily, can improve the scalping of screening quality.
Scalping of the present invention, comprise upper shell and lower house, bottom lower house, supporting leg is set, on, arrange respectively in lower house, lower screen cylinder, on, lower screen cylinder is all fixed on by pressure ring, on lower house, the pressure ring of fixing upper screen cylinder is positioned at bottom screen cylinder, the pressure ring of fixing lower screen cylinder is positioned at the top of lower screen cylinder, on, in lower screen cylinder, rotor is set, rotor bottom arranges belt wheel, belt wheel connects motor by driving belt, motor is arranged on end rail, on, between lower house, respective rotor arranges charging aperture and the outlet of good slurry, upper shell top and lower house bottom arrange tail slurry mouth respectively.
Upper shell can be arranged to trapezoidal, and lower house can be symmetrical arranged with upper shell, makes good slurry chamber little, broad in the middle up and down, makes screening pressure balanced, operates steadily; Compact conformation is reasonable, and stress equalization, can improve screening effect; The machine adopts outer-flowing type structure, under a complete totally enclosed state, and the equipment of band pressure step sizing; Slurry enters in sieve nest with certain pressure from tangent line in the middle part of casing, slurry is divided into two parts, and a part flows to upper screen cylinder, and a part flows to lower screen cylinder, rotate the effect of the pressure differential inside and outside the positive negative pulse stuffing and screen cylinder produced at rotor under, good pulp fibres is got married and start a new life by screen cylinder and is starched mouth discharge.Do not discharged from upper and lower two tangential tail slurry mouths by the tail slurry of sieve aperture.Like this, effectively shorten the time of staying of impurity in sieve district on the one hand, reduce the possibility of impurity recycling, improve screening effeciency; Prevent heavy seeds from causing damage to rotor, screen cylinder on the other hand, the service life of extension device.
Described upper and lower screen cylinder includes screen cylinder body, and screen cylinder body is set to corrugated, and corrugated screen cylinder body comprises rod, arranges through hole between rod, and rod is all positioned at inside corrugated screen cylinder body, and corrugated screen cylinder body peripheral is distributed with reinforcing ring.Screen cylinder body surface is designed to ripple type, the contact surface of slurry and screen cylinder body can be increased, the cleaning performance of screen cylinder is good, good slurry is reduced by the resistance of screen cylinder body, increase good slurry throughput, make whole screen cylinder be utilized most effectively, the setting of reinforcing ring ensure that the intensity of screen cylinder body simultaneously; Through the test in paper plant, the screening capacity of corrugated screen cylinder improves 5% to 10% than traditional screen cylinder, there has also been service life and significantly improves.
Described rotor comprises symmetrically arranged rotor top and rotor bottom, in between rotor top and rotor bottom, installing hole is set, on the lateral wall of rotor top and rotor bottom all on have end to end smooth curve rotor, at the end to end place of adjacent smooth curve rotor to being welded with wearing layer.The sidewall of rotor top and rotor bottom is distributed with up and down end to end smooth curve rotor, impurity can be avoided too much to cause rotor serious wear, substantially increase service life; Line, the long impurity of rope class can not hang on smooth curve rotor, equipment are run more steady; Prevent smooth curve rotor from smashing impurity and by screen cylinder, causing the energy consumption of follow-up equipment to increase; Slurry is mixed, avoids concentration phenomena, make slurry faster by screen cylinder, improve production efficiency; Curvilinear motion is level and smooth, and produce uninterrupted action of low-voltage pulse during smooth curve rotor rotational, negative pressure is little and the duration is long, is conducive to clean screen cylinder, improves output; Can rotor life be improved to being welded with wearing layer, reducing production cost.
Described motor is arranged on electric machine support, installs and regulate jackscrew between electric machine support and end rail, and driving belt is V-belt.Electric machine support bottom is fixed on end rail, by regulating the elasticity of jackscrew adjustment V-belt, and then the normal operation of the equipment of guarantee.
Described upper shell top arranges cover, and cover both sides arrange hanger.Hanger is arranged at cover top, can facilitate the dismounting of cover, is convenient to the maintenance of the cleaning of device interior, the replacing of screen cylinder and equipment.
The invention has the beneficial effects as follows:
Rational in infrastructure compact, operate steadily, screening quality can be improved; In screening effect, production capacity, have great raising, energy consumption obviously reduces; Adopt corrugated screen cylinder, the contact surface of slurry and screen cylinder can be increased, to improve cleaning performance; Rotor is distributed with end to end smooth curve rotor up and down, impurity can be avoided too much to cause rotor serious wear, substantially increase service life; Line, the long impurity of rope class can not hang on smooth curve rotor, equipment are run more steady; Prevent smooth curve rotor from smashing impurity and by screen cylinder, causing the energy consumption of follow-up equipment to increase; Slurry is mixed, avoids concentration phenomena, make slurry faster by screen cylinder, improve production efficiency, reduce production cost.
