Definitions
- the invention relates to a hydrocyclone plant with several hydrocyclones according to the Preamble of claim 1.
- hydrocyclones are used to make liquids containing substances from different sinking behavior, due to strong centrifugal forces fractionate. So it is e.g. possible in a pulp suspension, as used to Production of paper is used to concentrate contained impurities and through a Rejektan gleich derive from the hydrocyclone. The of impurities freed fraction, namely the accept, is led through the accepts connection and used further.
- These processes are known per se, as is the fact that a good effect is only guaranteed if the hydrocyclones do not have a certain size exceed. In a hydrocyclone plant, for larger throughputs is therefore a plurality - often even a variety - of hydrocyclones needed. These are then flowed through in parallel by the liquid to be purified, which means that the liquid flow into a multitude of smaller partial streams must be split. For this, e.g. Distribution and collection devices, such as will be described below.
- a convenient distribution and collection device is usually to create so that the distribution of the liquid streams is largely uniform.
- Another Demands on hydrocyclone plants of this type is their simplicity to them to produce inexpensive.
- the hydrocyclones for maintenance purposes easy to exchange. The fulfillment of all these demands is in the past existing systems not satisfactorily resolved.
- the invention is therefore based on the object, a hydrocyclone plant with simple Make the means so that the hydrocyclones easily attached and removed can be and a secure grip is guaranteed even with overpressure.
- the inventively designed distribution and collection device contains for the inlet and for the process e.g. each a relatively large cylindrical metal tube or an oval metallic flow part. This can be the mentioned threaded bolts be welded. For the screw connection are only a few and In addition, cheap standard parts needed. Since the hydrocyclones are made in series, e.g. be poured or sprayed, the flanges can be in one piece with the Establish connections.
- Fig. 1 shows an example of a hydrocyclone 1, which in the inventive manner the distribution and collection device 5 is connected and thus a part of Hydrocyclone plant forms.
- the liquid to be cleaned passes via a lower inlet pipe 10, to which the inlet connection 2 is connected, into the hydrocyclone 1.
- the liquid flows into the Acceptance connection 3 and then into the accept pipe 11, which is above the Inlet pipe 10 is located.
- Inlet connection 2 and accept connection 3 are each with a flange 6 provided by means of threaded bolts 9 and nuts 8 at the cylindrical side wall 7 of the corresponding tubes is releasably secured.
- Reject connection 4 is here as usual at the lower end of the hydrocyclone.
- FIG. 1 Another side view of the hydrocyclone plant shown in Fig. 1, again only Sectionally, Fig. 2 shows.
- the inlet pipe 10 and the accept pipe 11 recognizable in side view.
- the connected to the upper pipe flange 6 is a Round flange, while the corresponding flange 6 'on the inlet pipe 10 as an alternative oval is drawn.
- two threaded bolts per flange are sufficient. It may be useful, the threaded bolt 9 only when mounting the hydrocyclone on the cylindrical side wall 7 réellesch spaen, since then any inaccuracies of the Pipe laying can be compensated. There is usually no additional Effort such as drilling or attaching reinforcements required.
- the threaded bolt Can simply be placed on the curved pipe wall and welded.
- connection to the distribution and collection device 5 takes place according to Fig. 3 and Fig. 4 with an elastic seal 14 which through the opening in the cylindrical side wall 7 is pushed through.
- Threaded bolt 9 and nuts 8 are in Fig. 3 drawn by dashed lines, since they are hidden.
- the seal has inside and outside the inlet and outlet pipe, a larger outer diameter than him Having opening in this tube.
- the outer diameter of the seal 14 at the Location that is located after insertion in the opening of the inlet or outlet pipe, is less than the diameter of this opening. This forms first, so before the connection of the hydrocyclone is in its end position, a gap 17 (s. Fig. 4).
- the bore of the gasket is conical, in such a way that it separates from outside inward, so narrowed in the mounting direction 18 of the flange 6. This will when retracting the connecting pipe, the gasket expands and settles inside the Distribution pipe on. Even so, the not completely excluded tolerances in the Production of hydrocyclones or hydrocyclone plant are compensated. Threaded bolt 9 and nuts 8 are shown in dashed lines, since they are hidden.
- the distribution and manifolds ie the inlet pipe 10 and the accepts pipe 11 are not arranged directly above one another, but offset so that the accept pipe 11 with the center axis of the hydrocyclone. 1 Aligns so that the accepts pipe 11 is perpendicular to the hydrocyclone 1.
- Acceptance connection 3 and inlet connection 2 are at right angles to each other Connection directions. This arrangement is favorable in many cases. Especially what the Compactness of the system, the simplicity of the connections and the safety of the Attachment of the hydrocyclone to the distribution and collection device 5 relates.
- the figure 5 shows yet another feature that not only here but also at other embodiments of the subject invention is possible. It can namely by an - here only hinted - adjusting 19 of the accepts 3 in the axial Direction are shifted. As a result, larger tolerances can be compensated. But this adjustment can have a further advantage because the assembly of Hydrocyclone is considerably simplified. It would then be e.g. first of all Feed inlet 2 into the inlet pipe 10. Subsequently, through Increasing the accepts connection 3 and the connection to the accepts pipe 11th getting produced. The use of seals as described in FIGS. 3 and 4 are advantageous. Then, as already described, the flanges 6 to the Threaded bolt 9 screwed, and without the hydrocyclones 1 at a additional bracket are attached, a secure grip is ensured.
- the hydrocyclone plant shown in FIG. 6 receives the suspension to be purified a distribution and collection device 5 'designed as a stationary cylinder.
- This Cylinder is inside by a horizontal partition 13 (dashed lines) divided transversely to the flow direction. Upstream of this partition wall 13, i. so inlet side, are the inlet connections 2 of the laterally arranged Hydrocyclones 1 and downstream of the partition 13, the accept connections 3.
- the Central axis of the hydrocyclones is in each case parallel to the cylindrical side wall. 7 arranged.
- Hydrocyclones can also be used so that the heavy fraction as accepts and the light fraction is used as a reject. With such an application will be e.g. specifically light impurities separated from a paper fiber suspension. Also for this purpose, a system according to the invention can be used by the Accept connection 3 of FIG. 1 or 2 serves as a reject connection. The accepts then fall at the outlet for the heavy fraction. Such circuits are known per se and therefore not specifically shown here.
