Definitions
- the invention relates to a hydrocyclone system with several hydrocyclones according to the Preamble of claim 1.
- hydrocyclones are used to move liquids containing substances from different sinking behavior due to strong centrifugal forces fractionate. So it is e.g. possible in a fiber suspension, such as for Production of paper is used to concentrate and contain contaminants derived from the hydrocyclone by a reject connection. That of contaminants The exempt fraction, namely the accept, is led through the accept connection and further used.
- These processes are known per se, as is the fact that a good effect is only guaranteed if the hydrocyclones are not of a certain size exceed. In the case of a hydrocyclone system designed for larger throughputs is designed, therefore, a plurality - often even a large number - of hydrocyclones needed.
- the liquid to be cleaned then flows through them in parallel, which means that the liquid flow into a variety of smaller sub-flows must be divided. For this, e.g. Distribution and collection devices like them to be used in the following.
- a suitable distribution and collection device is usually to be created in such a way that the distribution of the liquid flows is largely uniform.
- hydraulic disturbances, eddies or the like can be avoided.
- Another The requirement for hydrocyclone plants of this type is their simplicity to them to be able to manufacture inexpensively.
- the hydrocyclones are also intended for maintenance purposes easy to exchange. The fulfillment of all these requirements is with the so far existing systems were not satisfactorily resolved.
- the invention is therefore based on the object of a hydrocyclone system with simple Design means so that the hydrocyclones are easily attached and removed and a secure hold is guaranteed even with overpressure.
- the distribution and collection device designed according to the invention contains for the inlet and for the sequence e.g. each a relatively large cylindrical metal tube or an oval one metallic flow part.
- the mentioned threaded bolts can easily do this attached, e.g. be welded on.
- For the screw connection only a few and also cheap standard parts needed. Since the hydrocyclones are mass-produced, e.g. poured or sprayed, the flanges can be made in one piece with the Make connections.
- Fig. 1 shows an example of a hydrocyclone 1 in the manner according to the invention the distribution and collection device 5 is connected and thus part of Hydrocyclone plant forms.
- the liquid to be cleaned gets into the system during operation via a lower-lying inlet pipe 10 to which the inlet connection 2 is connected, into the hydrocyclone 1. After proper cleaning, the liquid flows into the Acceptance connection 3 and then into the acceptance tube 11, which is above the Inlet pipe 10 is located.
- Inlet connection 2 and accept connection 3 are each with provided a flange 6, which with the help of threaded bolts 9 and nuts 8 on the cylindrical side wall 7 of the corresponding tubes is releasably attached.
- reject port 4 is located at the lower end of hydrocyclone 1 and serves to remove the heavy parts collected in the hydrocyclone Reject collecting tube 16.
- the connection to the reject collecting tube 16 is advantageous parallel to the other connections.
- As a holder for the parts of the distribution and Collecting device 5 is used only as an attachment frame 15.
- the Hydrocyclones themselves are already sufficient due to the compounds described firmly anchored.
- FIG. 1 Another side view of the hydrocyclone plant shown in FIG. 1, again only FIG. 2 shows sections of the inlet pipe 10 and the accept pipe 11 recognizable in side view.
- the flange 6 connected to the upper tube is a Round flange, while the corresponding flange 6 'on the inlet pipe 10 as an alternative is drawn oval.
- two threaded bolts per flange are sufficient. It may be useful, the threaded bolts 9 only when the hydrocyclone system is installed on the weld cylindrical side wall 7, because then any inaccuracies Pipe laying can be compensated. There is usually no additional Effort such as drilling or attaching reinforcements is required.
- the threaded bolt can simply be placed on the curved pipe wall and welded on.
- connection to the distribution and collection device 5 expediently takes place 3 or FIG. 4 with an elastic seal 14 through the opening in the cylindrical side wall 7 is inserted.
- Threaded bolts 9 and nuts 8 are in Fig. 3 drawn in dashed lines, since they are covered.
- the seal has inside and outside of the inlet or outlet pipe a larger outer diameter than him Has opening in this tube.
- the outer diameter that the seal 14 on the Has a spot that lies in the opening of the inlet or outlet pipe after insertion, is smaller than the diameter of this opening. This initially forms, that is before the connection of the hydrocyclone is in its end position, a space 17 (see. Fig. 4).
- the bore of the seal is tapered, so that it is from externally inwards, ie narrowed in the mounting direction 18 of the flange 6. This will When the connecting pipe is retracted, the seal expands and lies inside the Distribution pipe. Even so, the tolerances in the Production of the hydrocyclones or hydrocyclone system are balanced. Threaded bolts 9 and nuts 8 are drawn in dashed lines because they are covered.
- the distribution and collecting pipes are, ie the inlet pipe 10 and the accept pipe 11 are not arranged directly one above the other, Instead, it is offset so that the accept tube 11 with the central axis of the hydrocyclone 1 is aligned so that the accept tube 11 lies vertically above the hydrocyclone 1.
- accept connection 3 and inlet connection 2 at right angles to each other Connection directions. This arrangement is favorable in many cases. In particular what the Compactness of the system, the simplicity of the connections and the security of the Attachment of the hydrocyclone to the distribution and collection device 5 relates.
- Figure 5 shows yet another special feature that not only here, but also at other versions of the subject matter of the invention is possible. Because it can by an - only indicated here - adjusting device 19 of the accepted material connection 3 in the axial Direction to be shifted. This allows even larger tolerances to be compensated for.
- This setting option can have another advantage because the assembly of the Hydrocyclones is considerably simplified. It would then be e.g. first the Insert the inlet connection 2 into the inlet pipe 10. Then can by Increasing the accept connection 3 also the connection to the accept pipe 11 getting produced.
- the use of seals as described in Figs. 3 and 4 is an advantage. Then, as already described, the flanges 6 to the Threaded bolt 9 screwed, and also without the hydrocyclones 1 on one additional bracket are attached, a secure hold is guaranteed.
- the hydrocyclone system shown in FIG. 6 receives the suspension to be cleaned a distribution and collection device 5 'designed as a standing cylinder.
- This Inside the cylinder is a horizontal partition 13 (shown in broken lines) divided across the direction of flow. Upstream of this partition 13, i.e. so on the inlet side, there are the inlet connections 2 of the side Hydrocyclones 1 and downstream of the partition 13 the accept connections 3. Die
- the central axis of the hydrocyclones is parallel to the cylindrical side wall 7 arranged.
- Hydrocyclones can also be used so that the heavy fraction is a good substance and the light fraction is used as a reject. With such an application e.g. Specifically light contaminants separated from a paper fiber suspension. Also a system according to the invention can be used for this by the Acceptable substance connection 3 of FIG. 1 or 2 serves as reject connection. The accepted material then falls at the outlet for the heavy fraction.
- Such circuits are known per se and therefore not specifically shown here.
