Description

Spiral separator

The part flow arrangement that the present invention relates to be used for improving on the spiral separator.

Spiral separator is to be used for being suspended in the equipment that the mixture of the high density granular of slurries and low-density particles is separated adding separator.Generally the helicla flute that supports with the spiral jack-post on the separator form.

Usually,, for example contain the water of suspension, be passed into the top of this groove, and permit liquid and solid crossheading and descending under the gravity effect slurry stream.If the shape of groove is selected correct, high density granular has mobile slower trend than low-density particles, and the trend that oriented groove inner edge is assembled under the influence of gravity.The heavy particle of some gatherings can utilize current divider and dispenser to remove.

Australia's application (46168/72) has been described one and has been had vertically extending splitterr vanes, and installs around the pivotal line of erectting relevant with taper or columniform dispenser.Dispenser on trough floor has the ratio that the convertible adjustment of vertical blade enters the aggregation in the dispenser.This device disadvantage is that maximum adjusting range is limited by the plane to the top of dispenser of necessity.Part flow arrangement is centered around above the dispenser and the dispenser plane is incorporated on the spiral fluted bottom surface, if the diameter of dispenser is too big, makes the normal shape of groove produce fierce distortion, and liquid stream is and then distortion also.In this case, when current divider forwards this position to, to such an extent as to that the splitterr vanes of protrusion also produce fierce liquid flow disturbance aggtegation is too little or do not had.

Know that also the taking-up amount of aggregation is to regulate by the radially slotted hole that setting is positioned at the adjustable-length on the trough floor.Such current divider is described by Australian patent specification 37175/78.The disadvantage of this device is the influence that adjustable mechanism is subjected to solid in the suspension easily.These solids the trend of blockage mechanism is arranged and also have since radially the existence of slotted hole increase distortion may with the difficulty on making, the trend that cyclone separator arrangement is had slacken.

The objective of the invention is to improve be used to shunt and take away the device of a part of particle and avoid or improve above institute address the disadvantage that has current divider now.

According to such opinion, the present invention is made up of following:

A kind ofly be used for separating the groove particle flow liquid that flows into spiral separator or the part flow arrangement of slurries, this device is by the splitterr vanes of a work edge with an adverse current and be positioned at being used for installing and having the work edge low side and the contacted blade mounting arrangement of trough floor is formed of trough floor top.Have on this erecting device along the route between radially outer that extends in trough floor and the inner radial by translational motion adjustment and the contacted position of this work edge.

In order to select, the blade working sword is movably on Curve Path.Curve Path be near the primary importance of groove inner radial wall to compare with primary importance be in apart from the big radial distance of inwall and also be the second place at the upstream end of primary importance.

In most preferred embodiment, splitterr vanes have a flexing arm by rail bar or the integral body of other guiding means supports above trough floor.In vertical and horizontal plane this arm be flexible and also guider allow work edge from a position when Curve Path is crossed in another position, maintenance contacts with the trough floor curved surface.So with respect to vertical plane, horizontal plane, or with respect under both situations, this route may be a curve.

The present invention is now only by the method description of example with reference to the accompanying drawings:

Fig. 1 represents the plane according to part flow arrangement of the present invention.

The part flow arrangement of Fig. 2 presentation graphs 1 is on the position of returning.

The section that the part flow arrangement III-the III line is got of Fig. 3 presentation graphs 1.

Fig. 4 presentation graphs 1 is by part flow arrangement partial cross-sectional view that IV-the IV line is got.

Shown with reference to the accompanying drawings the part flow arrangement device have a blade 1 and from the blade-section longitudinal extension and also with blade be the arm 10 of an integral body.

The adverse current end of blade-section 1 has work edge 11, when it uses, flows towards liquid.In plane, sword 11 is illustrated in the intersection point place on two curved blade faces 12,13.Sword 11 from washing trough base plate 2 more contacted extending upward.

Blade-section 1 and the arm 10 that is connected are formed by flexible material such as rubber or elastomeric polyurethane integral die in the present embodiment.Flexible splitterr vanes part 1 is to contact with the base plate face of groove 2, and is hung by the rail bar 3 on the working face top that is contained in groove and isolated with it and the top that be supported on flexing arm 10.Be guided the inner radial of groove to such an extent as to the angle of the 1 pair of liquid of splitterr vanes stream is the liquid stream of such inboard to shunting work edge 11, if requirement is arranged, it can be taken away at dispenser 20 places.This dispenser 20 is positioned at the downstream part of part flow arrangement work edge 11.Curved surface 12,13 helps by desired mode with liquid stream at sword 11 places separately.

By along guiding rail bar 3 travelling arms 10, the position of blade can be moved with respect to trough floor.Fig. 2 illustrates that arm 10 moves to the second place, and blade is to represent and its work edge is to represent with 11A with 1A among this figure.

In the embodiments of the invention shown in Fig. 3, adopted one to have the arm 10 in cross section as shown in Figure 4.In the cross section, have two leaves stick up 5 contact with the base plate of groove and also groove 6 on the end face of arm 10, be fit to rail bar 3(Fig. 4 in expression) the slip interlock.Rail bar 3 and leaf stick up 5 makes part flow arrangement keep facing the position of liquid stream.Arm 10 is to rotate around rail bar 3, and therefore leaf sticks up 5 maintenances and engages with trough floor when the relative rail bar 3 of arm slides.

The lower surface of arm 10 is that leaf flat or as shown in Figure 4 sticks up shape, and it is that rail bar 3 must have correct angular relationship in the opposed slot surface that a disadvantage is arranged.(not having illustration) in other embodiments provides an arm 10, and it has circular sword down and rotates the rail bar 3 that abundant width is arranged around longitudinal axis for the arm of stability 10 stops it.On rail bar 3, can be provided with the flange that part flow arrangement top or side are worked arbitrarily, to replace the effect of central channel.

, another embodiment provides the part flow arrangement of the upper surface with semi-circular cross-section and has worked in associated rail bar scope.

Most preferred embodiment of the present invention provides some to surpass the advantage of existing part flow arrangement.

Part flow arrangement can use with splitter box, and its groove working face profile (by the cross-sectional illustration of the axis of screw) is a curve.

Because it is straight that rail bar there is no need on horizontal plane or vertical plane, the structure of a separate system realizes moving around with the desired big like that radius of spin easily, and does not make the shape of groove produce undesirable distortion.Part flow arrangement can move to outside the slurry stream position or all remove, so that in the time need not assembling, disturb minimum.

A design of flexible part flow arrangement can be made into the shunting arm that links to each other and is suitable for various difform grooves, only needs the profile of rail bar is changed over the shape that adapts to groove.

Blade-section and arm can be easily integrated poured with synthetic rubber.And the rail bar that has support carriers can be by the reinforced plastics injection molded, or uses the stainless steel manufacturing better.

This device does not need high-accuracy structure effectively to use.Because the aggregation between part flow arrangement and trough floor does not make the stuck tendency of part flow arrangement.The helicla flute of employing part flow arrangement according to the present invention need not offered slotted hole or fixing device for installing on trough floor.

Make arm 10 and also can preferentially adopt other structural materials.Other embodiment are giving splitterr vanes mobile can imagining easily on the walking mechanism on rail bar or the guide rod or other devices on the fixed route, and are within the scope that this paper discloses.According to part flow arrangement of the present invention not needs be used for liquid is flowed the opening part that the guiding of separated part enters cylinder.But can enter the part guiding of liquid stream a close passage or enter other separators, or only make the skew of not separated liquid stream under certain conditions.

For skilled in the art people, because the guidance of this paper has been obviously to a certain extent.The feature of embodiment generally contains under the situation in the invention that does not break away from disclosure herein, can revise or make up, and this modification or combination are in this scope.
