Abstract
The utility model discloses a scum discharge device of an outflow pressurized screen, which belongs to the technical field of paper making equipment. The scum discharge device comprises a big end down conical cylinder disposed inside a top cover of the pressurized screen, the small end of the conical cylinder is fixedly connected with a scum outlet of the pressurized screen, and the big end of the conical cylinder extends to the inside of the pressurized screen. On the premise of not changing throughput, the scum discharge device can reduce feeding pressure and power consumption, and simultaneously realize smooth discharge of scum and meets requirements of production.
Description
Technical field
The utility model relates to the paper making equipment technical field, relates in particular to a kind of light slag discharger of outer-flowing type pressurized screen.
Background technology
In paper industry, the effect of screening cleaning equipment is exactly to reduce the impurity that does not meet manufacturing technique requirent in the pulp suspension to greatest extent, to obtain clean good slurry.A few days ago, the outer-flowing type pressurized screen is little with its volume, screening effect good and production capacity is strong etc., and advantage is widely used in paper industry, is applicable to the screening of the wood pulp before the bleaching, all kinds of straw pulp, secondary stock, is applicable to that also bleaching back and paper machine stream send the selected of portion's paper pulp.The outer-flowing type pressurized screen is that a slurry is with the step sizing equipment of pressing under the state of complete closed.The unscreened paper pulp that has pressure is oriented in a tangential direction by the pulp-inlet pipe of body upper and enters the screen cylinder inboard, pass through sieve plate by the good slurry of the pressure official post inside and outside the screen cylinder, the blade that rotates in screen cylinder simultaneously can make the mobile of paper pulp be further improved, the head of blade can produce a moderate pressure, promote slurry and pass through sieve plate, blade and longitudinal axis have an inclination angle, can promote slurry descends, impel thick slag to flow to the bottom of pressurized screen, discharge from scum pipe, good slurry by sieve plate is drawn from the good slurry pipe at body middle part, and the light slag in the slurry floats to topmost by slurry mobile eddy current that produces in screen cylinder, discharges by light slag outlet.
The light slag outlet of existing outer-flowing type pressurized screen all is opened on the pressurized screen top cover, the pressurized screen operation time need reach higher and advance to starch pressure and certain turnover slurry pressure reduction could be discharged light slag, therefore must use for pressurized screen by the more powerful stock pump of adapted, to satisfy the pressure demand that the light slag of pressurized screen is discharged, power consumption is big, is unfavorable for energy-conservation.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of outer-flowing type pressurized screen light slag discharger, under the prerequisite that does not change treating capacity, can reduce into slurry pressure, reduce power consumption, realize the smooth discharge of light slag equally, meet the needs of production.
For solving the problems of the technologies described above, the technical solution of the utility model is: the light slag discharger of outer-flowing type pressurized screen, comprise a up-small and down-big conical shell, described conical shell is positioned at the light slag chamber of described pressurized screen, the small end of described conical shell is fixedlyed connected with the light slag outlet of described pressurized screen, and the big end of described conical shell stretches to the inside in described light slag chamber.
Owing to adopted technique scheme, the beneficial effects of the utility model are: owing to be provided with a conical shell that stretches to pressurized screen inside below the light slag outlet of pressurized screen, make the light slag in the slurry also not arrive light slag outlet, in time discharge just by the big end collection of conical shell.Under the identical situation for the treatment of capacity, with not improvement comparison before, the light slag discharge of existing outer-flowing type pressurized screen need be advanced to starch pressure and be reached more than the 0.15MPa, turnover slurry pressure reduction reaches 0.02-0.03MPa, light slag just can be discharged smoothly when adopting the laggard slurry pressure of this programme to reach 0.1MPa, can adopt lower-powered stock pump, reduce power consumption 30% compared with before-improvement, save power consumption greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, light slag outlet, 2, conical shell, 3, top cover, 4, stock inlet, 5, grout outlet.
The specific embodiment
As shown in drawings, the light slag discharger of a kind of outer-flowing type pressurized screen, comprise a up-small and down-big conical shell 2, described conical shell 2 is arranged at the inside, light slag chamber of described pressurized screen, described light slag chamber is the cavity of below that is positioned at the top cover 3 of pressurized screen, the small end of described conical shell 2 exports 1 with the light slag of described pressurized screen fixedlys connected, and the big end of described conical shell 2 stretches to the inside in described light slag chamber.
Its course of work is as follows:
The unscreened paper pulp that has pressure is oriented in a tangential direction by the stock inlet 4 of body upper and enters the screen cylinder of pressurized screen, pass through sieve plate by the good slurry of the pressure official post inside and outside the screen cylinder, the blade that rotates in screen cylinder simultaneously can make the mobile of paper pulp be further improved, the head of blade can produce a moderate pressure, promote slurry and pass through sieve plate, blade and longitudinal axis have an inclination angle, can promote slurry descends, impel thick slag to flow to the bottom of pressurized screen, discharge from slag-drip opening, good slurry by sieve plate is discharged from the grout outlet 5 at body middle part, light slag in the slurry floats to topmost by slurry mobile eddy current that produces in screen cylinder, big end by conical shell 2 is collected, and discharges by light slag outlet 1.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
