Fig. 4 there is shown screen bars for the part sectional drawing by the sieving cylinder.
Fig. 5 is the cross sectional representation of another embodiment of screen bars.
Fig. 1 is the side view of screen apparatus.There is shown sieving mechanism 1.Described screen apparatus is positioned on the plane such as ground 2.Solids extract mechanism 3 is positioned at the port of export of screen apparatus.Extraction mechanism comprises an elongate body portion 4 and the screw mandrel conveying device (not drawing among the figure) that is driven by motor 5 like this.Be positioned at below the port of export 6 of extraction mechanism 3 is solids treatment device 7.This solids treatment device can comprise a tipping bucket or other suitable solids treatment container.Described extraction mechanism 3 is used for carrying and ejecting solid or the part solid that installs the port of export certainly.
Sieve is a rotatable cylinder basically.Cylinder is made up of a plurality of parallel screen bars of circumferentially extending around cylinder and a plurality of ribs or support member along the cylinder longitudinal extension.Fig. 4 (below will address) shows the characteristics of this screen bars.
Fig. 1 shows screen apparatus at one end.Screen apparatus has sieving cylinder 8.Has the baffle plate 9 of lifting on the cylinder.This of some kind of lifting baffle plate 9 circumferentially equally spaced circumferentially is provided with and radially extension in cylinder around cylinder basically.Cylinder also has feeder 10, feeder 10 be positioned at the cylinder peak under to admit from promoting the solid matter that baffle plate 9 falls.This helps solid matter to kick up and be convenient to from the screen cloth face of cylinder 8 this solid or part solid matter are taken out.
Cylinder one end is that the other end of opening is that (not shown) is sealed at least basically by an end cap then.The entrance point of cylinder is centered on by wall 11, and the sealing means that wall 11 usefulness are traditional for example is sealed on the cylinder to prevent that thin pulp to be filtered from flowing to the screen cloth outside with neoprene latex.
For sieving solid from liquid or thin pulp or part solid matter, cylinder is driven by motor 12 and rotates around horizontal axis.Because screen bars is around the extension of roll circumference ground rather than along the cylinder longitudinal extension.So they do not have very big plane to move in liquid or thin pulp, thereby can not allow above fibrous matter is wrapped in.The plane surface of screen bars helps to make thin pulp to flow through on the length direction of each screen bars.Therefore improved the efficient of screen cloth.
Fig. 4 shows the part sectional drawing by the sieving cylinder.It illustrates screen bars 13 and is made up of basal plane part in facing 14 and the side that has tapering that ends at most advanced and sophisticated 15.Therefrom as seen, the triangular in shape basically or taper of the cross section of screen bars.Arrange the screen bars that is provided with parallel to each other, because the existence of basal plane part 14 has elongate gap 16 is passed through liquids mass-energy from the gap flat basically surface thereby can provide.
It should be noted that when liquid from the screen cloth face by the time because the tapering of screen bars has increased the voidage in gap 16, thus strengthened flowing of the liquid stream that from gap 16, passes through, thereby make liquid stream accelerate the performance that speed has improved device.Can know thus and find out that screen bars differs and is decided to be the triangular-section, T-shape net bar also is feasible fully.Under the situation of T type net bar, the vertical position of " T " of the horizontal component of " T " and supporter will constitute the surface.
In addition, Fig. 5 shows a kind of the have head 18 triangular in shape basically of amplification and the screen bars of an elongate body portion 19.Because elongated net bar body portion 19 can allow liquid produce effectively linear movement, thereby the flowing of liquid stream of flow velocity from gap 16 further strengthened.Arrow A is represented the liquid flow path direction substantially near the liquid of the screen surface of device.When liquid flows to the sieving surface of head 18, liquid stream just will enter in the gap that is formed by net bar 20 and 21; In case enter the gap, the area in gap greatly increases, thereby liquid will be along the mobile speed of passing through that has strengthened fluid of the direction of arrow B indication.
Have on the screen roller to promote retaining device 9, it is provided with at interval along the circumferencial direction of cylinder, radially extend internally and with screen surface shape at an angle.Cylinder has support member 17.Screen bars 13 is partly supported by the lifting baffle plate 9 that is welded on the screen bars inner surface.In addition, also has the support member of forming by horizontal stripe 17.Horizontal stripe 17 can be provided with promoting between the baffle plate 9 at interval at each.The appropriate intervals distribution that promotes baffle plate and support member 17 is very important, and the screen bars body is when getting too closely, and for example, the screen bars when using longitudinal extension it is found that easy generation wrapping phenomena.
What be worth proposition is to the present invention includes a kind of improved screen bars and screen apparatus, is suitable for this screen bars is used in the sieving cylinder in order to sieving solid from liquid.Yet, what deserves to be mentioned is that the present invention can be used for any occasion of solid being sifted out by the sieving face of being made up of screen bars from liquid.
