Description
Technical field
The utility model relates to a kind of pulp processing equipment, especially a kind of paper pulp lightweight scummer.
Background technology
At present, in pulp production, scummer is to be used widely, and scummer generally is divided into heavy scummer and lightweight scummer, the slagging-off effect of heavy scummer is very good, but the processing of light impurity is a great problem of domestic paper-making industry always, and existing lightweight scummer separates not thorough, the slagging-off weak effect, the fibre stream vector is big, and advance to starch concentration and generally be not more than 0.5%, cause great lot of water resources and power waste, have a strong impact on the quality of the especially high-grade paper of paper.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, power consumption is few, can effectively remove the paper pulp lightweight scummer of various light impurities.
For solving the problems of the technologies described above, the utility model comprises the scummer housing, and its design feature is that described scummer housing middle and upper part is the upper conical-tube of tapered diameter, and the bottom is the gradually big slower conical tube of diameter; At the top of upper conical-tube oral area the eddy flow that reaches down in the scummer housing inner chamber is installed and forms device, the top that eddy flow forms device is equipped with upper cover, and upper cover is provided with stock inlet; Be provided with capping down in the bottom of slower conical tube, lower seal covers and is provided with good slurry pipe, descends the center of capping that the scum pipe that reaches the slower conical tube bottom also is installed certainly.
Described eddy flow forms device and has discoid base plate, is provided with down the deflection cone of stretching from the centre of base plate; Top being equipped with opposed to each other by two approximate semiorbicular sidewalls of base plate constitutes chamber, and the two side is at the interlaced formation guiding gutter of radial direction, and the guiding gutter top is provided with closure plate, is provided with the deflector that tilts to extend to base plate along guiding gutter export department.
Described stock inlet is mounted obliquely within on the upper cover, and the stock inlet direction is pointed to the center line of chamber.
The diameter of described scum pipe hypomere is greater than the diameter of its epimere.
After adopting said structure, because being installed, the eddy flow that reaches in the scummer housing inner chamber down forms device in upper conical-tube, make slurry in scummer housing inner chamber, form stable spiral eddy flow, slurry time of staying in scummer is longer, separation for light impurity is more thorough, because of light impurity proportion low weight, in with the slurry rotary course, gather the center gradually, from the deslagging mozzle, discharge, and slurry is bigger owing to proportion, is thrown toward wall and edge good slurry pipe discharge, the fibre stream vector reduces greatly, and it is simple in structure, power consumption is few, and is easy for installation, and the system maintenance expense is low.Experiment showed, and use this structure, pressure can form stable spiral eddy flow when 190Kpa, under equal conditions, and the more existing scummer 5-8% that cuts down the consumption of energy.The utility model can adapt to concentration is removed light slag in slurries such as the various secondary stocks below 1%, chemical pulp, Straw Pulp requirement.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that eddy flow forms device among Fig. 1;
Fig. 3 is the A-A cross-sectional view of Fig. 2;
Fig. 4 forms the perspective view of device for eddy flow.
The specific embodiment
With reference to accompanying drawing, this paper pulp lightweight scummer has the scummer housing, and scummer housing middle and upper part is the upper conical-tube 4 of tapered diameter, and the bottom is the gradually big slower conical tube of diameter 7.At the top of upper conical-tube 4 oral area the eddy flow that reaches down in the scummer housing inner chamber is installed and forms device 3, this eddy flow forms device 3 and has discoid base plate 14, is provided with down the deflection cone of stretching 15 from the centre of base plate 14; Top being equipped with opposed to each other by two approximate semiorbicular sidewalls of base plate 14 constitutes chamber 12, the two side is at the interlaced formation guiding gutter of radial direction (16,17), the guiding gutter top is provided with closure plate 11, be provided with the deflector 13 that tilts to extend to base plate 14 along guiding gutter export department, guiding gutter designs for axial symmetry, guarantee upper conical-tube 4 inner chamber stress balances, make slurry form the spiral eddy flow of steady ordered, under the effect of deflection cone 15, eddy flow is more stable, use deflector 13, avoid occurring turbulent phenomenon.The top of eddy flow formation device 3 and the top oral area of upper conical-tube 4 are integrally welded.The middle part of upper conical-tube 4 is provided with fastener 5, and the top that eddy flow forms device 3 is equipped with upper cover 2, and upper cover 2 is provided with stock inlet 1, and stock inlet 1 is mounted obliquely within on the upper cover 2, and the stock inlet direction is pointed to the center line of chamber 12, in order to strengthen flow velocity.Be provided with capping 9 down in the bottom of slower conical tube 7, following capping 9 is provided with good slurry pipe 10, center from capping 9 down also is equipped with the scum pipe 6 that reaches slower conical tube 7 bottoms, it is the top that extends upper conical-tube 4 and slower conical tube 7 connecting portions on the scum pipe 6, the diameter of scum pipe 6 hypomeres can avoid light slag to stop up scum pipe, and slower conical tube 7 is the gradually big shape of lower diameter greater than the diameter of its epimere, assurance has enough spaces that the good slurry slurry pipe 10 of getting married and start a new life is discharged, and reduces fiber loss.
