Technical field
The utility model belong to the pulping and paper-making industry to secondary stock and float before the pulp sifting equipment technical field, be specifically related to dense pressurized screen in a kind of outer-flowing type.
Background technology
Be used for secondary stock at present, float before the equipment that screens of slurry a lot, as: in-flow pressurized screen, outer-flowing type pressurized screen, net fore worker etc. all can be realized its processing.Problem is these equipment mechanism complexity, and floor space is big, required advances to starch the pressure height, causes cost, the operating cost height of equipment, can not satisfy user's instructions for use.For example: twin drum net fore worker, structure is more loaded down with trivial details relatively, operates more numerous and diversely relatively, and production capacity is little, and is also relatively large to the wearing and tearing of screen cylinder, production cost and maintenance cost height.
The utility model content
At the problem that prior art exists, the purpose of this utility model be to design provide a kind of simple in structure, operating cost is low and the outer-flowing type of good separating effect in the technical scheme of dense pressurized screen.
Dense pressurized screen in described a kind of outer-flowing type, comprise support, be provided with the cylindrical shell and the motor of loam cake on the support, it is characterized in that covering on described the light impurity outlet is set, set gradually stock inlet, grout outlet and tail slurry mouth on the described cylindrical shell barrel from top to bottom, in the cylindrical shell cavity screen cylinder is set, rotary drum is set in the screen cylinder, rotary drum is connected with drive of motor.
Dense pressurized screen in described a kind of outer-flowing type is characterized in that described loam cake and cylindrical shell fixedly connected by the securing member that is provided with.
Dense pressurized screen in described a kind of outer-flowing type is characterized in that described loam cake middle part is provided with the light impurity outlet.
Dense pressurized screen in described a kind of outer-flowing type is characterized in that being provided with respectively on described stock inlet and the grout outlet diaphragm pressure gage.
Dense pressurized screen in described a kind of outer-flowing type is characterized in that the sieve aperture that is provided with on the described screen cylinder is hole sizer or slotted screen, and described slotted screen is machining ripple seam or rod ripple seam.
Dense pressurized screen in described a kind of outer-flowing type is characterized in that described rotary drum comprises rotor blade, rotor support and studdle.
Studdle can be regulated gap length between rotary blade and the screen cylinder in time according to the concentration of slurry and treating capacity.
Dense pressurized screen in above-mentioned a kind of outer-flowing type, simple in structure, reasonable in design, whole device comprises motor and the cylindrical shell that is arranged on the support, compact conformation; Light impurity outlet, stock inlet, grout outlet and tail slurry mouth reasonably are set on loam cake and cylindrical shell, and reasonably adopt the structure of rotary drum and screen cylinder, make the screening effeciency height; Whole device adopts totally-enclosed pressure to advance slurry, and slurry does not mix with air, does not produce foam, has improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-motor; The 2-rotary drum; The 3-screen cylinder; The 4-cylindrical shell; The 5-securing member; The outlet of 6-light impurity; The 7-loam cake; The 8-stock inlet; The 9-grout outlet; 10-tail slurry mouth; The 11-support.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, dense pressurized screen comprises support 11 in a kind of outer-flowing type, and support 11 is welded by general steel plate, and whole equipment is play supporting role.Be provided with the sealing mouth of a river and bearing lubrication pouring orifice in the support 11.Cylindrical shell 4 and motor 1 have be arranged in parallel on the support 11.Cylindrical shell 4 is welded into by stainless steel coiled sheet circle.The upper port of cylindrical shell 4 is provided with loam cake 7, adopts securing member 5 to fixedly connected between loam cake 7 and the cylindrical shell 4.The securing member 5 main engage thread that adopt are fixed.The middle part of loam cake 7 also is provided with light impurity outlet 6.
Set gradually stock inlet 8, grout outlet 9 and tail slurry mouth 10 on cylindrical shell 4 barrels from top to bottom, and each connector place be furnished with flange alive and with take over to install.Also on stock inlet 8 and grout outlet 9, be provided with diaphragm pressure gage simultaneously, help the control of pressure in the cylindrical shell 4.Fixedly installed screen cylinder 3 in the cavity of cylindrical shell 4, the sieve aperture that is provided with on the screen cylinder 3 is hole sizer or slotted screen, and slotted screen can be machining ripple seam or rod ripple seam.The inside of screen cylinder 3 is provided with rotary drum 2, is made up of rotor blade, rotor support and studdle, and studdle can be regulated gap length between rotary blade and the screen cylinder in time according to the concentration of slurry and treating capacity, and each part is stainless steel material entirely.Rotary drum on main shaft, is provided with belt pulley by baffle plate, bolted on the main shaft, belt pulley and motor 1 are in transmission connection, and the running of motor 1 drives rotary drum 2 rotations.
During work, after slurry enters screen cylinder 3 from stock inlet 8, rotation by pressure differential inside and outside the screen cylinder 3 and rotary drum 2 makes the acceptable fiber in the slurry flow to outside the screen cylinder 3 by sieve aperture (or sieve seam), discharge from grout outlet 9, the slag slurry of staying in the screen cylinder 3 is discharged through tail slurry mouth 10 under the promotion of slurry pressure and rotary drum 2 rotors, some light impurities are discharged from light impurity outlet 6 under the action of the centrifugal simultaneously.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
