Description

ln many industrial applications, such as within different chemical industrieswhere various chemicals have to be mixed with different suspensions of rawmaterial or into combinations of raw material, it is of high importance tohomogenize media having different properties such as different densities to obtainhomogenous suspensions. Such industries include paint manufacturing and pulpand papermanufacturing.
Within the pulp and paper industry, throughout the fiberline, i.e. thedifferent process steps involved when converting wood chips or other fibrous rawmaterial into pulp, there are several positions where mixing apparatuses are usedto mix different kind of media into the pulp suspension. The treatment mediaadded to the fiber suspension may for example be for heating, delignification orbleaching purposes. Often the treatment media are in gaseous or liquid state.
When mixing treatment media into a fiber suspension, it is of highimportance for the mixing result that an even or homogenous distribution isachieved.
Cylindrical mixers are provided in a wide range of configurations. Forexample, the rotor of the mixer may have a center axis aligned with or arrangedperpendicularly to the general flow direction of the media. Also, the outlet and inletof the mixer may both be positioned axially with respect to the center axis of therotor, or one of the inlet or outlet may be positioned perpendicularly to the centeraxis of the rotor. ln many cylindrical mixer configurations, particularly wherein theoutlet is arranged perpendicularly to the inlet and a center axis of the outlet isperpendicular to a center axis of the rotor, or in a tangential direction in relation tothe rotor, there is a remaining rotation of the media flowing out from the mixer, e.g. the pulp suspension. 2 This remaining rotation of the pulp suspension may cause a separation ofmedia or fluids when the mixed media have different densities due to thecentrifugal force, which is an undesired phenomenon particularly frequent whengaseous media are mixed with media with higher density such as pulp.
Thus, there is a need for improved mixing apparatuses for mixing media orfluids with different density properties and, in particular, for mixing apparatuses formixing treatment media into a fiber suspension, e.g. lignocellulosic pulp suspension.
SUMMARY OF THE INVENTION An object of the present invention is to provide an improved mixingapparatus for mixing media or fluids with different density properties.
Another object of the present invention, is to provide an improved mixingapparatus for mixing treatment media into a fiber suspension, e.g. lignocellulosicpulp suspension These and other objects are achieved by the present invention by meansof a mixing apparatus for mixing media or fluids according to the claims.
According to an aspect of the present invention, there is provided a mixingapparatus for mixing fluids, for example, a gaseous medium into a pulpsuspension. The mixing apparatus comprises a housing having a mixing chamber,at least one inlet opening communicating with the mixing chamber. The inletopening enables fluids to be fed into the mixing chamber. A drive shaft isconnectable to a drive device for rotation of the drive shaft in operation and a rotoris arranged in the mixing chamber and is adapted to be connected to the driveshaft to rotate with the drive shaft. At least one outlet is provided in the housingand is communicating with the mixing chamber. The at least one outlet iscommunicating with an outlet duct for enabling a discharge of mixed fluids. Therotor has a rotor axis extending through the mixing chamber and being concentricwith the drive shaft, wherein the rotor includes mixing elements arranged aroundthe rotor and along its extension. The rotor includes a discharge end arranged withdischarging elements for discharging the fluids radially. A stator is arranged in themixing chamber including stator openings allowing mixed fluids discharged by thedischarging elements of the rotor to flow radially through the stator openings fromthe mixing chamber and further toward the at least one outlet, whereby a 3 tangential movement of the discharged fluids is prevented. The stater is encircied in a radial direction bv a diseharae space deiimited hv an interior waii of thehousing the discharde end ef the rotor and the stator. The discharee spaceeernsnunieates tfvith the eutiet duct via the at ieast ene outšet wherein duringeeeratšon. fštsšds are fefced to fiow titroudti ttie stator epenšnds and in a serni~cireuiar ttow in the discharge space tetvards the at ieast one outiet and otitiet duct.
The present invention is based on the insight that by, during discharge ofthe fluids, Stopping or preventing the remaining rotation of the fluids, e.g. the pulpsuspension, and thus the tangential movement of the fluids by means of the stator,the separation of fluids with different density properties caused by the centrifugalforce can be minimized. This effect is also improved by the uniform radialdischarge of fluids from the mixing zone within the mixing chamber.
According to an embodiment of the present invention, a center axis of theoutlet duct is perpendicularly, e.g. radially, displaced in a direction towards the atleast one outlet in relation to a center axis the rotor. ln embodiments of the present invention, an interior volume of the outletduct increases in proportion to a volume of the discharged fluid in a flow direction.
According to embodiments of the invention, the stator is shaped as tubularelement. ln embodiments of the invention, the stator openings is arranged radiallyadjacent to and outside the discharging elements of the rotor in a flow direction.
According to embodiments of the invention, the stator openings aredistributed along the stators entire circumference to provide a symmetric dischargeflow of fluid. ln embodiments of the invention, the mixing elements of the rotor areprotrusions with a curved or angled trailing surface in a direction of rotation of therotor.
According to embodiments of the invention, the mixing elements of saidrotor are distributed along substantially entire longitudinal extension of the rotor. ln embodiments of the present invention, the discharging elements of the rotor are protrusions curved or angled in a flow direction. 4 samma-inie-ates--with--the-eastiet-daset--vi-a--the--a-t--ieast--eneat:i:Eetï--xivifiereiifg--during ei:feelar-flow-in"the-däsena-arge--spase--tewarfds-the--at-least--ene-eutiet»arteš--eutle-t--duetfFurther advantageous embodiments of the device according to the presentinvention and further advantages of the present invention emerge from the de- tailed description of embodiments.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS ln the drawings, similar or corresponding elements are denoted by thesame reference numbers. Generally, in the drawings, arrows indicate the directionof the flow of fluid in the mixing apparatus, into and out of the mixing apparatus.
For the purpose of this disclosure, the term longitudinal refers to thedirection along which a body, part or element has its greatest extension. Further,when the term longitudinal is used in connection with the axes of shafts or similar,the longitudinal axis corresponds to the rotational axis of the shaft or similar.
With reference first to Fig. 1, the mixing apparatus 10 comprises a housing12, wherein the interior thereof is called a homogenization chamber or mixingchamber 14 with an inlet duct 16 having an inlet 18 into the mixing chamber 14.Further, the mixing apparatus 10 comprises an out|et duct 20 having an out|et 22 from the mixing Chamber 14 and a rotor 24 arranged axially with the direction offlow from the inlet opening 18 and transverse to the direction of flow to the outlet22.
The housing 12 is, in this embodiment of the present invention, preferabiyof a cylindrical, she|| or helix shaped design, as shown in Fig. 5. The housing 12 isfurther provided with an end part or end cap 26. The end cap 26 includes asubstantially central opening for a shaft 28 of the rotor 24 with necessary sealing,and possibly bearings for the shaft 28.
The substantially cylindrical wall of the housing 12 is, as explained above,provided with inlet and outlet 18, 22. Preferably, the shape of the inlet opening 18such that a center axis and an axis of symmetry that is concentric with the centeraxis RR of the rotor 24 and the shaft 28.
The outlet 22 is in some embodiments of the present invention shaped asa rectangle as shown in Fig. 3. Fig. 3 illustrates the mixing apparatus 10 and theoutlet 22 schematically in a direction perpendicular to a center axis RR of the rotor24 and shaft 28.
The outlet duct 20 is, according to preferred embodiments of the presentinvention, shaped such that a center axis Rou of the outlet duct 20 is radiallydisplaced in a direction towards the outlet 22 in relation to the center axis RR of therotor 24 and such that an interior volume of the outlet duct 20 increases inproportion to a volume of the discharged fluid.
Hence, the rotor 24 is mounted to the shaft 28 in the mixing chamber 14and rotates with the drive shaft 28. The shaft 28 is driven by a motor, for example,an electrical motor. The rotor 24 has a number of mixing elements 32 arrangedaround the rotor and along its longitudinal extension.
Further, the rotor 24 includes a discharge end 34 arranged with dischargingelements 36 for discharging the fluids in a direction substantially radially, inrelation to the center axis RR of the rotor 24 towards to outlet 22 and outlet duct20.
The purpose of the mixing elements 32 is to cause turbulence in the fluidsor media and thereby to obtain a homogenization or mixing of the fluids or mediaand to avoid a separation of, for example, gas from a medium. However, as theskilled person realizes, the shape and design of the mixing elements 32 as well as their number and exact location on the rotor and in relation to the inner wall of the 6 housing, to the inlet opening, depend on the medium or media to be treated, theconsistency of the medium or media, gas content of media, volume flow throughthe mixing chamber, amount of gas added to medium or media to mention a fewinfluencing parameters. ln addition to cause turbulence, the mixing elementscauses a flow of media through the mixing chamber towards the end part of therotor, where for example, the flow velocity of the medium or media can beregulated by means of the inter alia the rotational speed of the rotor.
The mixing elements 32 can, according to certain embodiments, bedistributed along the longitudinal extension of the rotor 24 in a gradually dislocatedmanner such that each line of mixing elements 32 are arranged with an inclinationin relation to the center axis RR of the rotor 24. Further, in certain embodiments,the mixing elements 32 are protrusions with a curved or angled trailing surface in adirection of rotation of the rotor 24 and the discharging elements 36 areprotrusions curved or angled in a flow direction.
A stator 38 is arranged at the end of the mixing chamber 14 adjacent to theoutlet 22. The stator 38 comprises a number of stator openings 40 arrangedradially adjacent to and outside the discharging elements 36 of the rotor 24 in aflow direction (indicated with arrows).
Preferably, the stator 38 is shaped as tubular element provided inside thehousing, for example as an insert lining or attached to the housing by means of forinstance bolts or screws. An important purpose of the stator 38 and the statoropenings 40 is, in essence, to function as an end of the mixing zone within themixing chamber 14 and to stop or prevent a tangential movement of thedischarged fluids when entering into and flowing through the stator openings 40.
A common problem in prior art mixing devices is a separation of gas frommedium during the outflow or discharge caused by remaining rotation in the mediasince the centrifugal force acts differently on gases compared to liquids or pulpsuspensions, for example. This is a pronounced problem when gas is mixed withpulp suspension.
Turning now to Fig. 4 which illustrates a schematical cross-section view ofthe mixing apparatus in a direction along the extension of the center axis RR of therotor 24 and shaft 28, i.e. the center axis RR of the rotor 24 points out from thefigure. As shown in Fig. 4, the stator 38 is encircled in a radial direction by a 7 discharge space 42 communicating with the mixing Chamber 14 via the statoropenings 40 and the outlet duct 20 via the outlet 22.The discharge space 42 is delimited by an interior wall 44 of the housing12, the discharge end 34 of the rotor 24 and the stator 38. ln Fig. 4, the flow ofmedia is indicated with arrows B, C, and D. Arrow B illustrates the flow of media inthe mixing chamber 14, where the rotation of the rotor 24 causes turbulence androtation of media and thereby homogenization and mixing of the media, forexample, gaseous medium and pulp suspension. Arrows C illustrate discharge ofmedia through the stator openings 40 and arrows D illustrate the semi-circular flowof media following the interior wall 44 of the housing 12 towards the outlet 22 andthen further to the outlet duct 20. As can be seen in Fig. 4, the volume of and thewidth (seen as a distance between the stator 38 and the interior wall 44 of thehousing 12) of the discharge space 42 increases in a flow direction.The invention shall not be considered limited to the embodiments illus- trated, but can be modified and altered in many ways by one skilled in the art,without departing from the scope of the appended claims.
