Definitions
- the invention relates to a sink separator according to the preamble of patent claim 1.
- Such a sink separator is known from European patent 0 114 923.
- the sink-floating chamber in this known sink separator - as is often the case with such sink separators - is divided into two chambers. It is a so-called two-chamber system.
- the two chambers are separated from each other by a partition. This results in relatively short sinking-swimming distances, so that a complete separation of the material to be separated, which often sticks together, is not achieved cleanly.
- a chamber is used as a pure sink-floating chamber.
- the sinking material sinks in this chamber to the bottom, which is arranged at an angle, so that the sinking material reaches the neighboring sinking material chamber.
- the material is excavated by a rotating paddle wheel.
- Floating material which adheres to and submerges with the heavier sinking material, rises in the sinking chamber after being released and is removed by the discharge device, i.e. the rotating paddle wheel, carried out, together with the sink material from which it is to be separated, since it cannot get back into the swimming chamber. This results in incorrect sorting.
- a device which serves on the one hand to separate sedimentable solids and floating materials from a liquid. It is therefore not a sink separator, in which the sinking material is to be separated from the floating material on the one hand.
- the known separating device has a container which is practically separated into two chambers by a transverse wall which forms the wall of an overflow. The second transverse wall remote from the first chamber is lower and serves as an overflow wall. This overflow only removes liquid.
- Floating materials are passed through the flow to the other end of the first chamber and are picked up there by a discharge screw which also transports the suspended matter from the lowest point of the container. So at the one end, the sediment and the floating material are transported away, i.e. not separated from each other. There is a separation between these solids and the liquid.
- the task of the cereals to be separated takes place outside the projected receiving length of the discharge device, that is, the sinking sinking material must first be diverted over the slope of the long leg on the ground and slide under the transverse wall into the second chamber in order to be there only at one point from the discharge device to be recorded and carried out.
- the object of the invention is to create a sink separator of the type mentioned at the outset which, with a simple structure, ensures safe separation of the material to be separated, preferably shredded material.
- the ascending float can flow again and again into the area from which it is then discharged via the overflow weir with float already floating above. Even floating material that initially sank with the sinking material and from the discharge device to the deepest Point is detected and is separated from the sinking material by this mechanical action and then reaches the surface again, is not carried away with the sinking material, but rather floats on the surface in the direction of the overflow weir with the other floating material. Due to the special arrangement of the lowest point between the overflow weir and the task, the "sink-swim distance" is very long, so that the material "can decide whether it wants to sink or swim".
- the sinking material can then sink down over the entire great length of the swimming distance into the area of the discharge device, which is also very long. So there is a long swim-sink section and discharge section for the sinking material and these two sections overlap, so that floating material that separates relatively late from the sinking material still gets into the area and into the flow that is necessary for the discharge of the Floats over the weir.
- a uniform laminar, uninterrupted flow is generated over the entire surface from the discharge end to the overflow weir of the channel-shaped sink-swimming chamber. This flow is not interrupted by a transverse wall or the like.
- the sink separator is also of simple construction as a single-chamber device.
- the lowest point lies between the overflow weir and the task and the discharge device begins at this lowest point, the task takes place above the receiving length of the discharge device and not point-wise, but over the entire length of the downwardly projected receiving length of the discharge device.
- This natural route filling ensures, on the one hand, that the filling is uniform and free of blockages and the wear-resistant, punctiform, mechanical material intake by the discharge device is avoided.
- the lowest point is "downstream" from the feed and above the discharge device.
- the sink separator according to the invention with its channel-shaped single chamber separates floatable solid material from sunken solid material, the liquid only serving as a separation medium.
- the floating material is removed at one end where the overflow weir is located, whereas the sinking material is removed at the other end.
- an advantageous embodiment is put under protection, in which the known shape of the triangle standing on the top is chosen so that the short leg adjoins the overflow weir, so that - as expressed above - the swimming - Overlap the sink section and discharge section of the discharge device for the sink material in a large area.
- This special shape with the triangle standing on the tip and the short leg adjacent to the overflow weir ensures that the task above the discharge device, i.e. not point-like, but takes place over the entire length of the discharge length of the discharge device projected downwards.
- the special form placed under protection in claim 2 represents a particularly advantageous embodiment.
- the sink separator can be designed as specified in claim 4.
- the formation as a band screw in the part which passes through the surface of the heavy sludge enables an unimpeded return of the heavy sludge, i.e. the slurry is not conveyed out of the sink-swimming chamber.
- Residual heavy sludge can run back into the sinking swimming chamber through the drainage surface according to claim 5.
- the sink separator is designed as protected in claim 6, then it is ensured that the flow of the floating material on the surface is not hindered by the feed plate.
- one or more additional filling pipes are arranged and directed accordingly, the flow on the surface in the direction from the discharge end to the overflow weir is strengthened accordingly, so that the safe and complete removal of the floating material via the overflow weir is ensured becomes.
- stirrers can be provided, as stated in claim 8, in order to ensure a quick and safe separation of floating and sinking material in this area.
- the system shown in FIG. 1 consists of a sink separator with a channel-shaped sink-swimming chamber 6 (FIG. 3) formed by parallel side walls, which is the heart of the system and forms a single-chamber system.
- the material to be separated is introduced through a feed plate or a feed chute 9.
- the lowest point is labeled 15. From this point starts a screw conveyor, the shaft of which is designated 11.
- One end of the channel-shaped sink-floating chamber is formed by an overflow weir 5, the other end is the discharge end from which the screw conveyor emerges.
- One or more additional items Filling tubes support the flow on the surface of the heavy slurry from the discharge end towards the overflow weir.
- the sediment discharged by the screw conveyor passes into a sieving device 14, which is supplied with washing water via pipes 19 and 20 and a pump 21.
- the floating material passes through the overflow weir 5 into a sieving device 16, which is also switched on via the pipes 19 and 20 into the wash water circuit.
- the slurry is pumped to the filling opening 7 and to the additional filling pipe (s) 8 via a pump 17.
- the receptacle for the heavy sludge is designated 18.
- the sink separator is shown in detail.
- the sink separator has an elongated, channel-shaped, slim sink-floating chamber 6, the bottom walls of which are designated by 1 and 2. Looking at the longitudinal section of FIG. 2 it is clear that the bottom walls 1 and 2 form a right-angled, isosceles triangle standing on the top 15 (lowest point) together with the surface of the heavy slurry.
- the heavy cloud is the hypotenuse.
- the long leg is the bottom wall 1, the short leg is the bottom wall 2.
- a screw conveyor forming the discharge device runs along the bottom wall 1 to the discharge end.
- the shaft of the screw conveyor is designated 11.
- the first part of the screw conveyor is made as a full screw 3 educated.
- the screw is then designed as a band screw, so that an annular space between the shaft 11 and the band screw 4 is left free.
- the end opposite the discharge end of the screw conveyor is formed by the overflow weir 5.
- the filling opening for the heavy sludge is designated 7.
- two further filling pipes 8 are provided, which are directed so that the flow towards the overflow weir 5 is supported by the heavy sludge entering here.
- Adjacent to these filling pipes is a feed plate or feed chute 9 which is at a distance or gap 10 from the surface of the heavy slurry.
- the area of the sink-swimming chamber, which lies at the discharge end of the screw conveyor above the surface of the heavy sludge, is designated by 13 and forms a run-off surface through which residual heavy beet can run back into the chamber.
- the material to be separated preferably shredded material
- the feed plate 9 in the middle area.
- Floating material floats on the surface in the direction of the overflow weir 5, this flow being supported by the addition of heavy turbidity through the filling pipes 8.
- Sinking material sinks more or less quickly into the area of the screw conveyor 3. The agitation and separation of the sinking and floating material is supported by the stirrer 12.
- the channel-shaped, elongated design of the sink-swimming chamber with parallel side walls and without hindrance and without a transverse or partition wall ensures a uniform laminar flow over the entire surface, which is supported and reinforced by the filling pipes 8. Despite the simple structure, it is ensured that floating material, in whichever area it floats, eventually flows to the overflow weir. Only sink material is discharged through the discharge screw.
