（Light dregs-removing device）.Scummer the '20s are just applied to paper industry, have been widely applied since nineteen fifty.At present, exist
In pulping and paper-making production process, the separation for the relatively small heavy seeds of the proportions such as sand, dust is most using traditional 606
Type scummer, the entrance that enters to starch of the scummer are cut to be circular, and slurry enters after scummer the contact formed with scummer inwall
It is the contact of point, is power consumption height the shortcomings that this scummer, it be 300kpa typically to enter to starch pressure, and good to starch pressure general
For 50kpa, enter pulp pressure differential typically in more than 250kpa；Separation for fine impurities is not thorough, and fiber loss amount is big,
And typically adapt into slurry concentration below 1.0%.Such as Chinese utility model patent application number CN200320106908.8 is disclosed
Middle low concentration slag removing device, including scummer housing, the scummer housing upper be garden tubular, in, bottom be tapered diameter
Cone cylinder shape, it is structurally characterized in that, is provided with the top garden barrel of scummer housing and extend into good slurry outlet therein, should
The side wall of garden tubular shell is provided with stock inlet, and the bottom of scummer housing is connected with slag-draining device, it is described enter to starch entrance its
To be cylindric, pars intermedia is tapered rectangular-shaped of bore for import department, with the connecting portion of scummer housing with helix tangentially
Direction connects.
And for example Chinese utility model patent application number CN200320106909.2 discloses the slagging-off that can remove plurality of impurities
Device, including scummer housing, described scummer housing are made up of upper, middle, and lower part, and its top is garden tubular, in, under
The cone cylinder shape of portion's tapered diameter, it is structurally characterized in that is provided with a mozzle, the side of scummer housing in scummer housing internal upper part
Wall is provided with into slurry entrance, the upper end of scummer housing, upper water conservancy diversion of the top provided with a tapered diameter for entering to starch entrance
Pipe, good slurry is provided with the side wall of upper mozzle and is exported, in described scummer housing, the ladder that bottom is tapered diameter
Type screw conic tubular, scummer housing lower end base are provided with heavy seeds discharger.Although above two scummer all reduces
The power consumption of system, but cost be the slurry to that can handle concentration requirement it is higher, typically below 2.5%.
Utility model content
The technical problems to be solved in the utility model is that existing scummer is lifted using reducing slurry concentration for the treatment of as cost
The capacity usage ratio of system, a kind of low pressure that can be handled low concentration slurry and can and reduce the power consumption of system is provided for this
Low concentration slag removing device in type.
The technical solution of the utility model is：Low concentration slag removing device in low-pressure type, it includes stock inlet, good slurry outlet, removed
Slag device housing and slag-draining device, the scummer housing are communicated with least one spirality pipe, the spirality pipe except
Spiraled on slag device housing direction extension and its inlet and outlet respectively be located at scummer housing not ipsilateral.
Spiral shape shunt conduit described in such scheme has two, and the central axis on scummer housing is symmetrical.
The improvement of such scheme is the sieve aperture by the way that slurry is shunted between the stock inlet and scummer.
The further improvement of such scheme is in outwards protuberance at slurry contact of the scummer housing with passing through sieve aperture
Arc.
The top of scummer housing described in such scheme is in cylinder, bottom diametrically diminishing cone.
The beneficial effects of the utility model are that part size is drained to outside scummer by spiraling by spirality pipe
After return turbulent flow formed in scummer, the slurry of low concentration in can handling, sieve aperture can improve slurry and be contacted with scummer
The jet velocity of point, the power utilization rate of system is improved, reduce power consumption.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
In figure, 1, stock inlet, 2, good slurry outlet, 3, scummer housing, 4, slag-draining device, 5, spirality pipe, 6, sieve aperture.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
As shown in figure 1, the utility model includes stock inlet 1, good slurry outlet 2, scummer housing 3 and slag-draining device 4, it is described
Scummer housing is communicated with least one spirality pipe 5, and the spirality pipe spirals extension on scummer housing direction
And its inlet and outlet is located at the not ipsilateral of scummer housing respectively.
Scummer housing in the utility model can be traditional cylinder, but preferably such as Chinese utility model patent
Structure disclosed in application number CN200320106908.8 and CN200320106909.2 is such, includes the top of cylinder, and
