Definitions
- the invention is based first of all on a hydrocyclic clone arrangement with a tangential inlet of the feed sludge, an upper run and a lower run, the feed being conveyed by a pump into a receiving chamber, the upper run also being passed into a collecting chamber, and being for the lower run
- a free outlet is usually provided (preamble of claim 1).
- Hydrocyclones with small nominal diameters have to be used to achieve high solids separation in the underflow or small separating grain sizes. As a result of the lower underflow nozzle diameter, the solids discharge capacity of small hydrocyclones is limited. Attempts have been made to remedy this disadvantage by working in several stages in order to achieve small particle sizes by first pre-separating in larger hydrocyclones.
- a hydrocyclone arrangement is also known from DE 195 08 430 AI.
- This reference is concerned with improving the separation of the solid phase in the hydrocyclone underflow and thereby ensuring a maximum solids discharge or a maximum thickening with fluctuating feed conditions.
- it is ensured that the entire hydrocyclone has no or a very reduced air core in itself during its operation, ie is completely or predominantly filled with liquid. This results in a corresponding increase in throughput.
- the structural means are relatively complex since, in accordance with DE 195 08 430 AI, in the case of multi-arrangements of small hydrocyclones, additional devices are required on each individual hydrocyclone.
- the characterizing part of this claim 1 that several, preferably identically sized hydrocyclones are provided and arranged spatially close to one another, that the overflows of these hydrocyclones into the for them common overflow collection chamber open that the common overflow collection chamber is designed as a pressure pot and is connected via an overflow manifold with an adjustable control valve and an associated control device for adjusting the volume split, namely the ratio of the volume flows of the upper reaches and lower reaches.
- the volume split can preferably be set or regulated by adjusting the control valve depending on the operating state.
- hydrocyclones The simple construction and mode of operation as well as the sharp grain size separation, in particular in the range between 5 and 250 ⁇ m, of hydrocyclones can be used here.
- the disadvantage of adjusting the individual hydrocyclones of a multi-shutter, given in the prior art, is smaller Hydrocyclones avoided since only one central adjustment device is provided.
- the volume split of all hydrocyclones which belong to this hydrocyclone battery can be adjusted or set via a single control valve, which can be located in an overflow collecting line which leads from the overflow collection container to the control valve.
- the invention further relates, according to claim 9 ff, to procedural measures for determining the operating state of the hydrocyclone.
- it is intended to carry out changes in the mode of operation, including the change in the so-called volume split in hydrocyclones.
- FIG. 2 a top view of FIG. 1 according to arrow II in FIG. 1,
- Fig. 4 another embodiment of the invention with a single hydrocyclone.
- FIGS. 2 and 3 show a preferred embodiment of the invention, namely a rotationally symmetrical arrangement of a larger number of hydrocyclones 8. In FIG. 2, only four hydrocyclones 8 are shown for this purpose . In contrast, this can also be a larger number of hydrocyclones. They are arranged around a common central axis 9.
- the inlet chamber 5 and the overflow collecting chamber 7 are preferably positioned centrally in this rotationally symmetrical hydrocyclone arrangement (see FIG. 2), with which (see FIG. 1) the longitudinal central axis of these two chambers coincides with the central axis 9 of the concentric hydrocyclone arrangement.
- the upper runs 11 of the hydrocyclones 8 are fed to the upper run collecting chamber 7 (see also FIGS. 2 and 3). 1 also shows the connections 12 from the inlet chamber 5 to the inlets of the hydrocyclones 8. In the top view according to FIG. 2, the connections 12 cannot be seen, since they are covered by the overflows 11.
- the connections 12 also feed the slurry tangentially to the respective hydrocyclone in a known manner (not shown in the drawing).
- the aforementioned connections 11 and 12 can be flexible hoses. Any air is present through the Rotation of the slurry in the interior of the collecting container, namely along the central axis 9. It can be discharged to the outside through the outlet valve 22.
- the underflows 13 of the hydrocyclones 8 are fed to a common discharge chute 14 and are discharged from there downwards in accordance with number 14 '.
- a control valve 15 is provided, which may have a servomotor 16 and is acted upon by the pressure in the overflow collecting tank 7 via an upper line collecting line 17.
- one of the hydrocyclones 8 can be designed as a measuring hydrocyclone 8 '.
- the level of the solid in its lower area is determined according to section 18 with the help of a
- Measuring cell determined is connected to a PC 19, which can also have a connection 20 to the servomotor 16 of the control valve 15 and a further connection 21 for driving the feed pump 3.
- the teaching according to the invention presupposes or includes that the upper courses 11 of the hydrocyclones 8, the upper course collecting tank 7 and the upper course collecting pipe 17 are largely free of air bubbles at the outlet of the collecting pot.
- the collecting container is provided with a ventilation valve 22, which is only indicated schematically here.
- feed lines in particular flexible hoses of the overflow lines 11 of the hydrocyclones, can likewise preferably be introduced tangentially into the upper region of the overflow collection container, so that a vortex flow is thereby formed in the interior of the overflow collection container.
- the above Overflow manifold 17 is attached tangentially in the lower region of the collecting container, so that a low swirl and low pressure loss exit of the upper course from this collecting container 6 into the upper course collecting line 17 is ensured.
- the overflow collecting container 7 can also have a manometer 23 for measuring the pressure in it.
- the selectivity can also be operated at the optimum, since the transition area from the strand to the screen discharge can advantageously be observed with a minimum of stored solid mass in the cyclone cone.
- continuous or quasi-continuous monitoring of the grain distribution or a characteristic grain size in the inflow or overflow and / or underflow of the "hydrocyclone battery” can also be used as an input measurement of the operating state of this hydrocyclone battery.
