Abstract
The utility model discloses a feeding fabric pulp spiral of double-roller pulp washer, which comprises a tube cover shaped housing, a feeding hole disposed on the housing, spiral blades disposed in the housing, a spiral shaft for connecting middle shaft of each spiral blade, and a drive device disposed at one end of the spiral shaft; the diameters of a series of spiral blades of the feeding fabric pulp spiral are gradually changed at different parts on the spiral shaft, the blade located in the middle of the spiral shaft has a minimum diameter and two maximum ends; the feeding hole is disposed in the middle of the housing; and the screwing directions of the series of the spiral blades at both sides of the feeding hole are opposite to each other. The diameters of the spiral blades of the feeding fabric pulp spiral are configured to be gradually changed, the diameter of the spiral blade on an inlet is minimal and that of the spiral blade on an outlet is maximal, so the materials are relatively uniformly distributed on the whole spiral section and are difficult to cause blockage and pulp reflowing.
Description
Technical field
The utility model relates to papermaking equipment, relates in particular to the charging cloth slurry spiral of two roller wash engines that a kind of paper mill paper pulp displacement washing uses.
Background technology
At present, the displacement washing of paper mill paper pulp adopts wash engine mostly.The filtration washing that is used for natural color pulp and bleached pulp to remove solid content, organic matter and the inorganic matter that dissolves in the slurry, guarantees the uniformity on the slurry concentration with concentrated.The charging mortar distributor is one of vitals of wash engine, and whether charging cloth slurry evenly influences the displacement washing effect along perfectly straight connecing.
The charging mortar distributor of two roller wash engines of prior art is exactly to adopt pipeline nature flow-guiding cloth slurry or charging cloth slurry spiral usually; The charging cloth of prior art slurry spiral, its structure comprise shroud shape housing, be located at charging aperture on the housing, be located at series helix blade, the helical axis that connects each helical blade axis that the equal diameter in the housing equidistantly is uniformly distributed with, the drive unit of being located at helical axis one end.During use, helical blade does not stop rotation by drive device drives, and the promotion slurry divides to fall when shroud shape housing advances and is transported to pressurizing unit.
Adopt such technology certainly to realize the charging cloth slurry of paper pulp; But because amount of slurry is different with the local inventory of outlet section (being divided by leading portion) at inducer (not dividing as yet), and helical blade to be equal diameter equidistantly be uniformly distributed with, thereby cloth is starched even inadequately; Can cause the closer to charging aperture and divide the more defectives of material that fall; And the too little meeting of blade causes slurry to pour in down a chimney, and blade too greatly then is prone to cause putty, and cloth slurry effect is desirable not enough.
The utility model content
For overcoming the deficiency of prior art, the utility model provides a kind of slurry amount of dividing that makes even relatively at whole spiral section, can not cause slurry to pour in down a chimney and putty, the charging cloth slurry spiral of two roller wash engines of cloth slurry better effects if.
The utility model is to reach the technical scheme that above-mentioned technical purpose adopts to be: the charging cloth slurry spiral of a kind of pair of roller wash engine, comprise shroud shape housing, be located at charging aperture on the housing, be located at helical blade in the housing, connect each helical blade axis helical axis, be located at the drive unit of helical axis one end; It is gradual change setting that its diameter of series helix blade of described charging cloth slurry spiral does not exist together on helical axis, and the blade diameter that is positioned at the helical axis middle part is minimum, and two ends are maximum, and charging aperture is arranged at the middle part of housing; Its precession direction of the series helix blade on charging aperture both sides is opposite.
The beneficial effect of the utility model is: because the helical blade diameter of charging cloth slurry spiral is a gradual change setting, import department is minimum, and the exit is maximum, distributes relatively evenly and is difficult for resulting in blockage and slurry pours in down a chimney at whole spiral section material.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.Wherein:
Fig. 1 is the sketch map of the utility model.
The specific embodiment
The structure of the utility model embodiment; As shown in Figure 1; The charging cloth of a kind of pair of roller wash engine slurry spiral, comprise shroud shape housing, be located at charging aperture on the housing, be located at helical blade 1 in the housing, connect each helical blade 1 axis helical axis 2, be located at the drive unit of helical axis 2 one ends; It is gradual change setting that series helix blade 1 its diameter of described charging cloth slurry spiral does not exist together on helical axis 2, and the blade diameter that is positioned at helical axis 2 middle parts is minimum, and two ends are maximum, and charging aperture is arranged at the middle part of housing; Series helix blade 1 its precession direction on charging aperture both sides is opposite.
Its operation principle is: because series helix blade 1 its diameter of charging cloth slurry spiral does not exist together on helical axis 2 is gradual change setting, and the blade diameter that is positioned at helical axis 2 middle parts is minimum, and two ends are maximum, and charging aperture is arranged at the middle part of housing; Series helix blade 1 its precession direction on charging aperture both sides is opposite.
At inducer, though material is many, blade diameter is little, and shroud shape housing and interlobate gap are big, are difficult for resulting in blockage; This moment is little owing to the little then blade of blade diameter pushes away the branch dynamics, and this section is also little by the percentage that the material under dividing accounts for this section total amount.
At outlet section, though blade diameter is big, shroud shape housing and interlobate gap are little, and material is few, also is difficult for resulting in blockage; This moment since blade diameter greatly then blade push away the branch great efforts, this section is also big by the percentage that the material under dividing accounts for this section total amount; This moment since blade diameter greatly then the little slurry that can not cause of housing and interlobate gap pour in down a chimney, like this, just distribute relatively evenly and be difficult for resulting in blockage and slurry pours in down a chimney at whole spiral section material.
The accommodation of version is set as helical blade 1 Diameter Gradual Change; The diameter that can also be the helical axis 2 of each helical blade 1 of connection is a gradual change setting; Helical axis 2 can be solid, and it is hollow also can to make the loudspeaker tubular, and each blade of equidimension is pressed the setting of spiral path arrayed.
The application of form as an alternative can also be the end that charging aperture is located at charging cloth slurry spiral, and then helical blade 1 diameter is pressed folk prescription and got final product to the gradual change setting.
Claims (1)
1. the charging cloth of two roller wash engines slurry spiral, comprise shroud shape housing, be located at charging aperture on the housing, be located at helical blade in the housing, connect each helical blade axis helical axis, be located at the drive unit of helical axis one end; It is characterized in that: it is gradual change setting that its diameter of series helix blade of described charging cloth slurry spiral does not exist together on helical axis, and the blade diameter that is positioned at the helical axis middle part is minimum, and two ends are maximum, and charging aperture is arranged at the middle part of housing; Its precession direction of the series helix blade on charging aperture both sides is opposite.
