Description

Can remove the scummer of plurality of impurities

Technical field

The utility model relates to a kind of pulp processing equipment, especially relates to a kind of scummer that can remove plurality of impurities.

Background technology

Scummer the '20s just is applied to paper industry, has obtained extensive use since nineteen fifty.At present, in the pulping and paper-making production process, for sand, dust geometric ratio heavy phase the majority that separates of less heavy seeds and light impurities such as plastic sheet, wax, foam is adopted two kinds of scummers, be heavy scummer and lightweight scummer, and use these two kinds of scummers generally to have following drawback simultaneously: 1, floor space is big, the power consumption height; 2, not thorough for the separation of fine impurities, the fibre stream vector is big; 3, advance to starch flow low, efficient is low.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of simple in structure, power consumption is few, can thoroughly separate various impurity, the scummer that can remove plurality of impurities that efficient is high.

The technical scheme that its technical problem that solves the utility model adopts is: comprise the scummer housing, described scummer housing is by last, in, three parts are formed down, its top is the garden tubular, in, the awl tubular of lower diameter convergent, its design feature is to be provided with a mozzle at scummer housing internal upper part, the sidewall of scummer housing is provided with into slurry inlet, the upper end of scummer housing, the top of advancing the slurry inlet is provided with the last mozzle of a diameter convergent, on the sidewall of last mozzle, be provided with good slurry outlet, in the described scummer housing, the bottom is the notch cuttype spiral awl tubular of tapered diameter, and bottom, scummer housing lower end is provided with the heavy seeds discharger.

As to improvement of the present utility model, described its import department of advancing to starch to enter the mouth is cylindric, pars intermedia is the rectangular-shaped of bore convergent, tangentially be communicated with screw line with the connecting portion of scummer housing, help slurry and enter the stable vortex of rapid formation in the scummer, slurry is fully separated in scummer; Be provided with the light impurity outlet at last mozzle roof, reach in the mozzle under this light impurity outlet; The sidewall of described heavy seeds discharger is provided with the heavy seeds outlet, and its bottom is provided with than the light impurity outlet; Or the sidewall of described heavy seeds discharger is provided with the clear water import, heavy seeds exports, and its bottom is provided with the recycled fiber outlet.

After adopting said structure, the slurry that enters scummer is done more stable vortex, the time that slurry stops in scummer is longer, by last, in, the scummer housing that following three parts are formed, wherein, notch cuttype spiral awl tubular structure is adopted in the bottom, be convenient to separate impurities, improve the slagging-off effect, the fibre stream vector reduces greatly, import department is cylindric, pars intermedia is that the rectangular-shaped slurry inlet that advances of bore convergent tangentially is communicated with the scummer housing with screw line, help slurry and enter the stable vortex of rapid formation in the scummer, slurry is fully separated in scummer, and slurry can form stable vortex under less pressure, reduced the power consumption of system, the bottom, lower end of this device can connect various forms of heavy seeds dischargers respectively, once can remove light simultaneously, heavy seeds, it is simple in structure, invest little, the efficient height.

The specific embodiment

Fig. 1, the scummer that can remove plurality of impurities shown in Figure 2, scummer housing 9 is made up of upper, middle, and lower part, be stainless steel, its top 6 is the garden tubular, middle part 7 is the notch cuttype spiral awl tubular of tapered diameter, bottom 8 is the notch cuttype spiral awl tubular of tapered diameter, two-stage notch cuttype spiral awl tube is set, be that slurry enters scummer with certain pressure along the hand of spiral, heavy seeds is bigger because of proportion, assembles downwards gradually, after running into the notch cuttype spiral awl tube of tapered diameter, separate once more, good slurry is upwards assembled gradually; Be provided with a mozzle 10 at scummer housing 9 internal upper parts, mozzle 10 and scummer housing 9 concentrics, the sidewall of scummer housing 9 is provided with into slurry inlet 1, this enters slurry inlet 1 its import department is cylindric, pars intermedia is the rectangular-shaped of bore convergent, tangentially be communicated with screw line with the connecting portion of scummer housing 9, scummer is inner to be contacted with scummer inwall formation face slurry entering like this, so advancing to starch pressure descends thereupon, under the pressure of 200kpa, can form stable vortex, thereby reduce the power consumption of system greatly, and can adapt to the requirement that different slurries are planted; The upper end of scummer housing 9, the top of advancing slurry inlet 1 are provided with the last mozzle 11 of a diameter convergent, on the sidewall of last mozzle 11, be provided with good slurry outlet 2, the outer tube wall top of good slurry outlet 2 is basic concordant with the top cover of last mozzle 11, can reduce into slurry pressure like this, a light impurity outlet 5 reaches in the mozzle 10 under last mozzle 11 roofs; Radially be provided with in bottom, the lower end of scummer housing 9 stretch out than light impurity outlet 4, the sidewall of bottom, scummer housing 9 lower ends is provided with heavy seeds outlet 3, heavy seeds exports 3 positions on the top than light impurity outlet 4, should form a removable heavy seeds discharger 12 than light impurity outlet 4 and heavy seeds outlet 3.If in the slurry during no light impurity, can outlet of the light impurity at top and bottom than light impurity port closing (shut off valve is not shown), this version is used for first section except that slag system.

Another kind shown in Figure 3 can be removed the scummer of plurality of impurities, be on the basis of said structure form, remove the light impurity outlet 5 that under last mozzle 11 roofs, reaches in the mozzle 10, the heavy seeds discharger 12 of its bottom is for only being provided with heavy seeds outlet 3 on its sidewall, other version is identical, when this version is discharged for no light impurity, be used for second section except that slag system.

Figure 4 shows that the heavy seeds discharger 12 of another kind of form, its sidewall is provided with clear water import 13, heavy seeds outlet 3, clear water import 13 is above heavy seeds outlet 3, its bottom is provided with recycled fiber outlet 14, this version is used for removing the final stage of slag system, can dock installation with the bottom of the scummer housing 9 of above-mentioned arbitrary version.
