The utility model comprises a base, a drive device, a rotor device, a sieve drum, a canister and an upper cover. The rotor rotates at outer side of the sieve drum, impeller of the rotor has thin impeller shape, pulp collection chamber has semi-ellipse shape, has smooth transition and has no dead angle, pulp outlet is designed into conic shape, new bar type corrugated sieve drum is used, support of bearing set has reverse conic shape. The utility model has the effects of simple structure, convenient operation, low equipping power, stable pulp discharge, small pulse, less blockage, stable performance and long operational life.
Description
Affiliated technical field:
The utility model relates to a kind of in-flow net fore worker, especially the screening plant of pulping and paper-making industry paper machine approach system low concentration slurry.
Background technology:
At present, equipment commonly used before the paper industry paper machine is the outer-flowing type pressurized screen, and rotor is arranged in the screen cylinder inboard, and the paper pulp tangent line enters the screen cylinder inboard, pressure official post acceptable fiber by the screen cylinder both sides flows to the screen cylinder outside by sieve aperture or sieve seam, discharges from the grout outlet at equipment middle part; Staying slag slurry in the screen cylinder moves downward through the tail slurry mouth and discharges.This mode easily makes impurity and fibre bundle get rid of to screen cylinder under action of centrifugal force, thereby stop up the sieve seam, reduce throughput, increase power consumption, screen cylinder, rotor wear and tear very fast, and partial impurities is passed through screen cylinder easily, cause pulp quality to reduce, and the pulp pulse is big, and online evenness is poor, influences the quality of manufacturing paper with pulp of paper machine.
Summary of the invention:
The purpose of the utility model in-flow net fore worker, provide a kind of in-flow net fore worker, it is to take the paper pulp tangent line to enter in the cavity between cylindrical shell and the screen cylinder, under the effect of high speed rotor rotated, paper pulp fiber is fluidization, pressure official post acceptable fiber by the screen cylinder both sides flows in the screen cylinder by sieve aperture or sieve seam, discharges from the grout outlet of equipment bottom; Staying the outer slag slurry of screen cylinder moves downward through the tail slurry mouth and discharges.The high speed rotation of rotor plays the self-cleaning effect to screen cylinder.
The utility model in-flow net fore worker takes following technical scheme to realize, it is to be made of support, transmission device, rotor arrangement, screen cylinder, cylindrical shell, loam cake.Support plays a supportive role to whole equipment, and accepts the good slurry by screen cylinder, offsets the pulse of slurry stream.Connect the slurry chamber and be the semiellipse shape, the slick and sly no dead angle of transition is beneficial to slurry and flows; Grout outlet is designed to cone shape, and to slow, the pulse of slurry stream is little by anxious for the pulp flow velocity.Transmission device is made of bearing bracket, bearing block, bearing, mechanical seal, main shaft, is used for support fixation screen cylinder and rotor arrangement, drives the rotor arrangement rotation.Reduce slurry enrichment phenomenon, bearing bracket is the reverse taper shape.Rotor blades is the slim vane shape, sideway swivel outside screen cylinder.Screen cylinder works to isolate impurity, purifies slurry, and the size of sieve aperture or sieve seam has determined the quality of good slurry.Screen cylinder adopts the stainless steel strip assembling welding of special shape to make, and effectively perforated area is big, and the surperficial rill that forms, and makes slurry stream at screen cylinder surface generation microturbulence, prevents that the wadding of fiber is poly-, increases throughput.The screen cylinder surface has strengthened ABRASION RESISTANCE than common screen cylinder after chromium plating is handled, improve service life.Cylindrical shell by corrosion resistant plate, go up lower flange and be welded, connect loam cake and support, the main region of carrying out for screening operation.Cylindrical shell is provided with stock inlet, and is furnished with pressure gauge connection.Loam cake is welded by flange and end socket, and the upper end is provided with exhaust outlet, so that in use discharge the air in the machine.
The effect of the utility model in-flow net fore worker is simple in structure, and is easy to operate, and it is low to be equipped with power, and the steady pulse of pulp is little, is difficult for stopping up stable performance, long service life.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is the structural representation of the utility model in-flow net fore worker.
1---support 2---transmission device 3---rotor arrangement 4---screen cylinder 5---cylindrical shell 6---loam cake
The specific embodiment:
With reference to accompanying drawing, the utility model in-flow net fore worker, it is to be made of support 1, transmission device 2, rotor arrangement 3, screen cylinder 4, cylindrical shell 5, loam cake 6.1 pair of whole equipment of support plays a supportive role, and accepts the good slurry by screen cylinder 4, offsets the pulse of slurry stream.Connect the slurry chamber and be the semiellipse shape, the slick and sly no dead angle of transition is beneficial to slurry and flows; Grout outlet is designed to cone shape, and to slow, the pulse of slurry stream is little by anxious for the pulp flow velocity.Transmission device 2 is made of bearing bracket, bearing block, bearing, mechanical seal, main shaft, is used for support fixation screen cylinder 4 and rotor arrangement 3, drives rotor arrangement 3 rotations.Reduce slurry enrichment phenomenon, bearing bracket is the reverse taper shape.Rotor blades is the slim vane shape, sideway swivel outside screen cylinder 4.4 of screen cylinders are isolated impurity, purify the effect of slurry, and the size of sieve aperture or sieve seam has determined the quality of good slurry.Screen cylinder 4 adopts the stainless steel strip assembling welding of special shape to make, and effectively perforated area is big, and the surperficial rill that forms, and makes slurry stream at screen cylinder surface generation microturbulence, prevents that the wadding of fiber is poly-, increases throughput.Screen cylinder 4 surfaces have strengthened ABRASION RESISTANCE than common screen cylinder after chromium plating is handled, improve service life.Cylindrical shell 5 by corrosion resistant plate, go up lower flange and be welded, connect loam cake 6 and support 1, the main region of carrying out for screening operation.Cylindrical shell 5 is provided with stock inlet, and is furnished with pressure gauge connection.Loam cake 6 is welded by flange and end socket, and the upper end is provided with exhaust outlet, so that in use discharge the air in the machine.
