Description

The invention relates to a method in the independent claims 1 and 2 specified type and a separating system specified in claim 5 type.

With such commercially used separation plants, disposal even under environmental regulations, more and more importance. Often practiced pumping out of the whole mixed with the torn up goods The content of the separator is unusually high. In or un Heating pipes lying behind the fat layer to heat the goods or waste pushing with a dozer blade are complex and unsatisfactory. An essential Licher disadvantage of the known methods is largely without disposal Odor nuisance (environmental protection) and as little as possible Dispose of residual liquid. It should be noted that commercial used separation systems mostly installed in or under the floor are so that the disposal without manual help from the operator must be carried out casually and quickly.

The invention has for its object a simplified and environmentally friendly process for the disposal of the material to be separated and one for carrying it out of the process to create a suitable separation plant.

The object is achieved either with the method according to claim 1 or the method according to the independent claim 2 solved.

The fact that the good for discharge in pasty or crumbly consistency brought, it can be brought away from the liquid level, whereby by the compression during disposal the proportion of the disposed of goods remaining liquid remains as low as possible. Even with forced cooling the expulsion of the residual liquid is promoted. In addition, the good is like this solidified that it is like a rigid object with technically justifiable Effort can be carried out. The advantage of forced cooling is that odor development is suppressed by the low temperature.

Appropriately, the good according to claim 3 by the action of heat made pasty and discharged in this easily disposable consistency.  

Alternatively, it is also expedient according to claim 4, the mecha to bring it into the crumbly consistency suitable for disposal. As Accompanying measure can be done by changing the liquid level the goods to be disposed of are promoted to the appropriate height for disposal be, however, the liquid that continues to drain into the de sewer system is determined, remains in the separation plant.

In the case of the above-described process variants, solidification is always involved or compressing not only reduces the residual water in the property, but also we owing to the reduction in surface area, the development of odors slowed down. The good is disposed of in a compact, almost dry form, which means no excess Disposal volume is wasted. The movement and Discharge resistance of the goods is low, disposal can be done quickly and without perform manual intervention from outside. Leaves in crumbly consistency the goods compress easily and fill into handy containers or containers len, whereby the transfer of the goods into the container without odor done for the environment.

An expedient embodiment of a separation plant for fat or starch gut-containing wastewater with at least a separation chamber in which the separation is settles well in the liquid level and / or at the bottom and at least a discharge device working to an overhead discharge opening has, emerges from claim 5. A screw conveyor with a comm Pression section disposed of with high efficiency and steadily and practically unaffected by impurities or solids contained in the goods. in the Compression section, the residual water is squeezed out and the goods on an opti times brought a small volume, whereby it has a relatively small discharge opening out of the separation chamber in a continuous line. Sealing measures are involved in this strand-like disposal of the goods to carry out particularly easily and effectively. The strand can be in rela Transfer small containers or other handy containers. From the crumbly good, the residual water runs away when it is disposed of, when it is compressed the residual water is excreted to a negligible proportion. Egg ne screw conveyor takes up little space in the separation chamber and is insensitive to interference.  

Another useful embodiment is set out in claim 6. Whether probably the one prepared for the screw conveyor (softened or broken open) Moved well to the screw conveyor by disposal can be done by a additional movement of the screw conveyor in the separation chamber of the whole Brush the liquid level and dispose of the material effectively.

The embodiment according to claim 7, in which the Screw conveyor permanently installed and the receptacle in the form of a trunk in the Ab separating chamber is movable back and forth.

The embodiment according to claim 8 is particularly useful because the Suction in the proboscis be the conveying movement of the goods to the screw conveyor favorable. The suction nozzle movement is controlled manually or automatically, oh ne that the separation chamber needs to be opened. The automatically controlled proboscis works like an automatic swimming pool floor cleaning device, the proboscis automatically the whole liquid level brushed.

In view of the largely automatic disposal is the execution form of claim 9 appropriate. The good takes effect without outside intervention sam brought out of the deposition chamber. The screw conveyor cooperie and let the residual liquid run back into the separation chamber or compress the goods to be disposed of to such an extent that only negligible residual liquid portion remains.

The embodiment according to claim 10 is also expedient because the up crushing devices and the feeders deliver the goods to the screw conveyor, that it carries. The breakers can be mechanical, hydraulic (with crushing jets), pneumatic (with compressed air jets) or electrical Kind (with vibrations or high-energy rays) or the like.

Another advantageous embodiment of a separation system for greasy Separated material that is ent in a layer that solidifies in the liquid level worry is apparent from claim 11. The conveyor element breaks the solidified layer or milled parts of it to convey the good  to bring snail and in the desired crumbly and for disposal bring consistency worth mentioning.

The disposal effect can be customized according to the embodiment of An saying 12 can be adjusted. With heating, the tendency of the goods is removed counteracted, on moving or rigid components in the separator Bake firmly or any movement ent considerable resistance to oppose.

A further alternative embodiment emerges from claim 13. The Conveyor element takes up the good pieces thanks to the negative pressure and conveys them over the scraper into the collecting trough, from which it is then removed is changed. The conveying element can also have the breaking effect Reinforce additional mechanical crushing or milling elements on the surface.

Here, too, the measure according to claim 14 is expedient because this is too contributes to rapid disposal.

Another advantageous embodiment is set out in claim 15. Here the material is brought into a pasty consistency by exposure to heat and is light deducted. If necessary, the puller works during the operation of the Ab cutting system continuously to avoid a layer that is too thick. If the Puller works slowly enough, we will also use the separator Unwanted swirling of the liquid is reduced to a minimum.

Another advantageous embodiment is set out in claim 16. The The bucket wheel or the bucket cylinder breaks the layer on the one hand and takes broken chunks with which are discharged in the collecting trough. On the The remaining water runs off there. Respectively. there is drainage in the collecting channel openings back to the separation chamber.

When using the screw conveyor, it is expedient according to claim 17 to heat at least parts of it in order to prevent the disposal of the goods to reduce and come to a residual water-free strand.  

Alternatively, the embodiment according to claim 18 is also expedient, where the layer of material is effectively broken up by the crushing links or the milling machine broken and processed for disposal. The crushing roller pair or Milling machines can automatically move back and forth in the separation chamber without that outside intervention is needed.

The embodiment according to claim 20 is also important because the smell tight connection reduces the environmental impact to a minimum. The rest Water-free goods are placed in individual containers or in a tubular waste disposal unit introduced strand, the tubular disposal strand as in the sausage production is divided into individual handy sections without there is an odor nuisance.

A targeted disposal of the goods brought in by the screw conveyor is ensured in the embodiment according to claim 21. Since the För derschnecke practically continuously promotes, it is important that it also un depending on their position within the separation chamber, always a discharge finds opening through which the strand of the goods to be disposed of to the outside or gets into an odor-proof container.

A further advantageous embodiment is set out in claim 22 the sediment or starch in a sludge trap below the liquid are offset. The screw conveyor, which can be used to dispose of the goods serves in the liquid level, is also used here, too Periodically dispose of sludge trap and settle it in the sludge trap te to get rid of residual water and in a good and environmentally friendly way to bring disposable strand form.

A structurally particularly expedient and effective embodiment is based Claim 23 out. The two screw sections cooperate optionally or continuously to remove the goods from the bottom of the separation chamber and on the other hand to dispose of the goods from the liquid level and without order to bring world nuisance into the containers used.

Since the expulsion of the residual liquid is particularly important, the execution  tion form of claim 24 expedient. Through the perforated inner tube compressing the material to be disposed of, the residual water to the outside presses so that it runs back into the separation chamber while the strand of almost dry and compacted goods is disposed of.

The embodiment is according to assembly technology and maintenance Claim 25 useful. The exposed drive motor is easy to cool and does not pollute. The shaft drives the snail reaching to the bottom. Between the pressure plates is due to the conveying action of the screw elements produces the compression of the goods, which drives out the residual water and also the almost homogeneous and residual water-free strand into the filling system presses.

Finally, the embodiment according to claim 26 is important because flankie In addition to the aforementioned construction measures, the level control used for disposal, the goods to be disposed of to the correct one To bring level or by means of goods movements compulsorily generated here to support disposal.
