In the paper-making pulping process, if the raw material paper pulp through size degradation directly enters scalping, to contain a large amount of heavy slags in the slurry, especially the paper pulp made of waste paper recycling, easily pulping equipment is produced serious wearing and tearing, shorten the service life of pulping equipment, also have a large amount of light slags also to have a significant impact for the paper products quality of making.
Scummer is that a kind of centrifugal principle that utilizes is removed the equipment that density in the slurry is different from the impurity of slurry, and stainless steel is adopted on scummer top, and the bottom is that polyurethane material is injection molded, and main body inner wall designs for screw cone.
Scummer can be used in the various slurry purification system.Comprise: mainly remove density in the slurry and be called the heavy scummer greater than the scummer of the heavy seeds such as the sandstone of slurry, iron filings; Mainly remove density and be called light dregs-removing device less than the scummer of the light impurities such as the mixing sicker of slurry, paraffin, hot melt adhesive, plastic sheet, foam, gas, ink particle.
Scummer complex structure, the slagging-off rate of prior art be low, the slagging-off weak effect, therefore demands providing a kind of simple in structure, the slagging-off rate high, fiber loss is few scummer urgently.
Summary of the invention
The utility model has overcome defective of the prior art, and the dregs removing from paper pulp that a kind of simple in structure, slagging-off rate is high, fiber loss is few is provided.
The purpose of this utility model is realized by following technical scheme:
A kind of dregs removing from paper pulp, comprise cylindrical shell, the cylindrical shell middle part is provided with feed head, feed head is provided with charging aperture, vortex pulp-inlet pipe and vortex is set in the cylindrical shell very starches pipe, and vortex pulp-inlet pipe and charging aperture are communicated with, vortex is very starched the inside that pipe is positioned at the vortex pulp-inlet pipe, vortex very starches the pipe lower end and vortex pulp-inlet pipe lower end is communicated with, and vortex is very starched the pipe upper end good slurry outlet is set, and vortex pulp-inlet pipe lower end arranges slag-draining device.
Further, feed head is the turbine type feed head.
Further, slag-draining device comprises deslagging box and the slag-discharging device that is communicated with deslagging box bottom, and slag-discharging device is provided with slag-drip opening.
Further, deslagging box bottom arranges Clean-plug.
Further, good slurry outlet is positioned at cylindrical shell near the place, top.
Further, charging aperture is positioned at the middle part of cylindrical shell.
The beneficial effects of the utility model are:
The utility model adopts vortex very to starch the inside that pipe is positioned at the vortex pulp-inlet pipe, two pipe boxes together and the lower end be communicated with, slurry enters the vortex pulp-inlet pipe downwards from the tangential direction of vortex pulp-inlet pipe cross section annulus, the good slurry outlet that good slurry is very starched the setting of pipe upper end from vortex is discharged, the slag-draining device that waste residue arranges from vortex pulp-inlet pipe lower end is discharged, effect of the present utility model is to remove heavy seeds by centrifugal force, the slagging-off rate is high, prevent that effectively heavy seeds is to the wearing and tearing of equipment, extension device service life, fiber loss is few, saves material, and simple in structure, easy for installation.
