As shown in figure 3, distributor 21 can be connected to screw assembly 31 or axis 15, and it is arranged in the cavity of shell 4, from And the distributor 21 is arranged on mouth (mouth) 3a (slurry is fed into the cavity of shell via it) of (i) feed conduit, Between all slotted vane 31a of (ii) screw assembly 31, to be fed into slurry and the distribution of cavity via feed conduit 3 Device 21 contacts and turns to the strainer 33a towards net-filter assembly 33 by distributor.Distributor 21 can be connected to axis 15 or spiral Component 31, so that distributor 21 is arranged between screw assembly 31 and net-filter assembly 33, and in axis 15,33 and of net-filter assembly Screw assembly 31 is rotated when driving and rotate via driving unit 7.The distributor 21 can be placed and configured to by size to warp It is guided by the intracorporal slurry of chamber that entrance (inlet mouth) 3a of feed conduit 3 is fed into shell, thus the slurry It is distributed along the angular range of pre-selection from the interior flat surfaces front surface of distributor 22a.Distributor 21 can be arranged and be matched by size It is set to and the intracorporal slurry of chamber for being fed into shell of the entrance 3a via feed conduit 3 is guided, so that the slurry is with pre- The speed of choosing is distributed towards net-filter assembly 33, the speed of the pre-selection it is similar to the speed that the strainer of net-filter assembly rotates (for example, X, the VELOCITY DISTRIBUTION in y and/or z-axis line be equal to strainer rotation VELOCITY DISTRIBUTION or the VELOCITY DISTRIBUTION in strainer rotation 50% Within, or strainer VELOCITY DISTRIBUTION 60% and strainer 33a VELOCITY DISTRIBUTION 140% between).The speed of the pre-selection can To be the speed in receivable velocity interval, or give in desired setting point value or desired VELOCITY DISTRIBUTION value Determine the speed (for example, in setting point value of selection or the 10% or 20% of desired VELOCITY DISTRIBUTION value) in tolerance.This is pre- The speed of choosing can be configured to the rotation speed that will be preselected or with the rotation speed in the rotational velocity range of pre-selection point The speed of amount is provided to output slurry, so that it is mobile in the direction of rotation that strainer 33a surrounds rotation to export slurry.Due to The configuration of one or more blocking portions (dam) of distributor is defined allows slurry to be moved to from the entrance of distributor in distributor By the channel of the distributor 21 when the outlet of distributor, so can also compare from the speed of the slurry of the outlet output of distributor The received slurry of the entrance of distributor speed more slowly or faster.It can also be due to allowing the entrance from distributor to be moved to distributor Outlet the configuration in labyrinth that is passed through of slurry, so speed ratio entering in distributor of the slurry from the outlet output of distributor The speed of slurry that mouth is received is more slowly or faster.The VELOCITY DISTRIBUTION for the slurry being discharged from distributor 21 can be configured to reduce Slurry sliding on the surface of strainer 33a, to reduce the abrasion that strainer 33a is subjected to.
As shown in figure 4, distributor 21 may include the first plate 22, there is interior flat surfaces 22a with front, before this, Interior flat surfaces 22a is surrounded by the periphery flange 22b for extending on flat surfaces or being extended from flat surfaces.At wall When closed position, which can extend from flat surfaces 22a towards the antetheca 6 of the mouth 3a of feed conduit 3 and shell It leaves for example between 20 and 80 millimeters (mm).In one embodiment, when wall is in the closed position, flange 22b can be from Flat surfaces 22a is extended 40mm towards the mouth 3a of feed conduit 3 and the antetheca 6 of shell and has the width of 50mm, thus Periphery flange is arranged on the side of distributor 21 or the outermost 50mm in face.Flat surfaces 22a can be inside from periphery flange 22b Extend to the center of distributor 21.Flat surfaces 22a can also have multiple hole 22c, be sized to receive fastener (example Such as, bolt or screw), for reaching axis 15 and/or screw assembly 31 by distributor, so that distributor 21 is connected to axis 15 And/or screw assembly 31.
In some embodiments, flange 22b can with limit flat surfaces 22a plate integrally cast or one landform At.In other embodiments, flange 22b can be it is with annular shape (for example, annular shape, rectangular loop shape or Polygon ring-shaped) flat item perhaps its welding of rod-shaped elements, suture or be fixed to plate or restriction in another way Other elements of flat surfaces 22a.The plate or other elements for limiting flat surfaces 22a can be circular, elliptical, arc-shaped Or polygon shape.
Flange 22b can be extended outward away from from flat surfaces 22a and be extended a distance towards the entrance 3a of feed conduit 3, thus Flange 22b can help a part for stopping slurry after slurry is by flat surfaces 22a deflection in a manner of blocking portion, will Slurry is spread along the relatively wide region of the strainer 33a of net-filter assembly 33.The distribution of the slurry as caused by flange 22b may be used also Facilitate the reduction of slurry with the strainer 33a of net-filter assembly 33 speed contacted.The slurry velocity as caused by flange 22b reduces Abrasion suffered by some regions of strainer 33a can be reduced with spreading, so that strainer 33a is compared with other conventional designs with more Uniform mode is worn, as the abrasion suffered by some positions because being diverted to the slurry of these positions in these conventional designs The speed of material is more considerably more rapid than the rate of wear of other positions with measuring.
It should be understood that distributor 21 can be configured to include more than one flange 22b.For example, the first flange 22b can be set Be set to it is adjacent with the periphery edge of distributor, and the second flange can be configured to relative to outer peripheral flange inwardly and from first it is convex It is intermarginal to separate, to limit gap or channel between two flanges.As other optional way, flange 22b, which can be, to be divided Only flange on orchestration, but can be not set into adjacent with periphery edge.Instead, flange can be upcountry arranged to The week in the face of the mouth 3a towards feed conduit at the center and distributor 21 in the face of the mouth 3a towards feed conduit of distributor 21 Between the edge of side.
The size and shape of each flange can be rectangle on cross section, or can be configured to have other shapes And size.For example, each flange can have triangular cross-sectional shape or can be configured to have another type of polygon horizontal Cross sectional shape is spread with providing desired slurry.As another example, the cross-sectional shape of each flange can be round, oval Shape, arc-shaped or other curved shapes.The outmost surface 22g that the shape of flange 22b can be configured to adjust flange 22b is prolonged The angle stretched, so that slurry is deflected to scheduled position or the band of position from the mouth 3a of feed conduit by distributor.For example, convex The outmost surface 22g of edge can be configured to it is flat, to be mounted in the cavity of shell 4 as shown in Figure 1 when distributor When the surface be vertical surface.
As another example, the outmost surface 22g of flange can be configured to relative to substantially vertical with complete relative to this It is bent vertically at the preselected angle between 5 ° and 85 ° or linear tilt.For example, the outmost surface 22g of flange can be it is flat It is sliding, substantially flat, extend linearly surface, with angle tilt between 5 ° and 85 ° or oblique, or it is highly preferred that with Angle tilt or oblique between 15 ° and 60 °.Such as another example, the outmost surface 22g of flange can be curved and can be with It is protrusion or recessed shape.
As the other example of different types of flange configuration, flange 22b may be configured such that the most external of flange Point surface is more wider than the penetrale 22h of the ontology for being attached directly to distributor 21 of flange.As another example, flange can It is configured so that the outermost portion surface of flange is thinner than the penetrale of the ontology for being attached directly to distributor 21 of flange. As still another example, one or more flanges of distributor can be configured to be limited in flange with curved shape Multiple grooves, such as wavy profile or in the flange for wherein defining multiple and different teeth spaced apart.
As the other example of different flanges, distributor can have each one or more formed integrally with one another convex Edge.One flange can have the thickness more smaller or larger than other flanges, thus the outmost surface of each flange be in it is different away from From.The change for the distance that outmost surface is extended can be configured to it is step-like, therebetween with or without the mistake on inclined-plane It crosses.Fig. 7,8 and 9 show the different examples of the outmost surface 22g of flange 22b.
Height, length or the thickness of flange can also be the arbitrary value in multiple and different values.For example, can limit flange from The thickness of flange for the degree that the surface 22a of distributor 21 is extended can be any value in multiple possible values.Similarly, The width of flange can be any value in multiple suitable values, such as with the width between 5-100mm, or has and be greater than The width of 100mm or be less than 5mm width.For example, if be arranged on the periphery edge of distributor, therefore flange 22b may be disposed on the outermost 5-100mm towards the side of the mouth 3a of feed conduit 3 of distributor.
In other embodiment, distributor 21 can be configured to fuel plate, with inclined or oblique table Face 22d, so that the inner part 22e peripheral portion 22f of surface 22d more adjacent than with the center of surface 22d of distributor 21 is more The mouth 3a for being outwardly directed to feed conduit 3 extends.For example, the central part or inner part 22e of distributor can be only 1-10mm thickness, and The outer peripheral edge of distributor can be the thickness between 30 and 100mm, so that the outer peripheral portion 22f score of distributor is matched The inner part 22e of device is thicker, and more inwardly the mouth 3a of feed conduit prolongs compared with the inner part 22e of distributor 21 It stretches.Surface 22d can be inclined generally smooth surface, such as flat or substantially flat surface, and inclination makes Obtain the peripheral edge portion that surface 22d extends out to distributor along angle, θ.The angle, θ can be between 1 ° and 65 ° Any angle, or the angle more preferably between 5 ° and 30 °.
Inclination or bottom surface 22d as defined by distributor 21 can help to the distribution of slurry and adjust to collide filtering Angle on the strainer of screen component, and help to reduce the energy of collision slurry, so that slurry is fed to the opposite of strainer 33a The part of inward position, while being dispensed on compared with flat, plane surface distributor 21 the bigger region of strainer On.
Furthermore, it is to be understood that the outflow jet from distributor 21 can be used for controlling and/or guiding the allocated to strainer The movement of the slurry of 33a.This can be by configuring one or more flanges of distributor 21 to guide the outflow jet of slurry to collide Point stops the natural flowing of the slurry of the distribution and realizes.This can assist in keeping slurry far from strainer 33a closest to spiral group The part at the top of part 31, so that facilitating slurry is diverted the intracorporal deeper inside of chamber that shell 4 is arranged in towards strainer 33a Part.
