The invention relates to a supplement and improvement of the washing device for beets or the same tubers or roots according to patent 1,189,480 with a load bearing the laundry Grate floor through which the items to be washed are guided under the simultaneous action of pressure medium jets which are at least partially directed from the underside of the grate bottom onto the laundry, whereby the beets are brought into the washing device without carrying liquid and by corresponding Training of the drainage device ensures that there is no supporting flow of liquid can train.

According to the main patent, the grate floor is fixed, and the strength of the pressure medium jets is selected so that that the laundry is lifted and messed up.

The invention aims at an arrangement in which there is an even better rolling movement of the items to be washed can be achieved than with the arrangement according to the main patent and with the transport even further is perfecting.

According to the invention, this is achieved in that the nozzles in a manner known per se in groups are arranged and each nozzle group is assigned a grate through which the dirty water drain can. You can z. B. combine a number of tubes to form a nozzle group, the Pipes are arranged in several rows one below the other and the lower rows of nozzles each have a gap the upper ones.

However, it is also possible to provide a container with a flat surface as a nozzle group, which with the nozzle holes is provided and is in one plane with the grids. In this group of nozzles are the Nozzles are arranged so close to one another that the beets are sprayed extremely intensively takes place from below, which are thereby whirled upwards.

It is already known in washing devices for fruit that conveyed on a traveling grate To spray laundry by means of nozzles arranged in groups. There is one for each group of nozzles other task too. In a known device close to a first group of nozzles, by means of which the laundry is sprayed with water from above, further nozzle groups via which the Items to be washed sprayed from above using various chemicals for preservation or disinfection will.

In another device, a group of nozzles is attached to a water spray device,

Washing device for beets or the like.

by means of the hot air is blown onto the laundry and this is dried in this way.
A washing device for beet leaves is also known, in which the beet leaves are conveyed via a reciprocating inclined shaking grate and sprayed from above and below by means of mutually offset showers for the purpose of cleaning.

To ensure that the beets are transported as evenly as possible, a rake with a Be provided on the conveyor belt running over two rollers, on the transverse to the transport direction and transport walls arranged perpendicular to the belt surface are attached.

The beets then go to the first washing zone and are released from the first group of nozzles escaping water or the like. Splashed from below. They are lifted, rolled and also washed on all sides. In the subsequent, grated part of this zone the dirty water drips off through the grate bars and is carried away or collected.

The beets now go to the next washing zone. In this they will first come back splashed from below and swirled up by the water emerging from the associated group of nozzles. In the adjoining grate part, the washing water is drained off or collected again. In The same washing process is repeated in the next following washing zone and in the associated grate part it only runs relatively little

Water containing dirt particles from or into a collecting container.

The washing system can have any number of washing zones, but it is a thorough cleaning normally three zones are sufficient.

The spray nozzles can also be arranged in a ring around the flow of beets. This arrangement is applicable regardless of which type and direction of transport is intended for the beets, namely in a horizontal, inclined, vertical, ascending or descending direction.

It is possible with the arrangement according to the invention, the laundry with a very small Thoroughly clean water consumption by washing the still dirty ones in a countercurrent washing process In the first washing zone, beets are washed off with the water contaminated by the following stages and washed in the subsequent washing zones with relatively less polluted water until finally, in the last stage, the items to be washed are sprayed with clear water. To this For this purpose, collecting containers for the water that are open at the top are arranged under the grates. That Fresh water is then fed to the group of nozzles in the last washing zone, so that those in the previous washing zone Wash zones that are relatively cleanly washed beets are rinsed with the cleanest of water. The water collected in a container underneath the grate of this washing zone becomes the nozzle group the previous washing zone and so on. Until the washing water in the first washing stage from the grate of which it flows off as waste water.

It is expedient to arrange in the recirculation system for recirculating the washing water from the Collecting container of a washing zone in the nozzle group of the preceding washing zone. Screening devices whose mesh size is smaller than the size of the nozzle openings of the previous washing zone.

The invention is illustrated below with reference to the schematic drawing of two exemplary embodiments explained in more detail.

F i g. 1 shows a cross section through a plant according to the invention;

F i g. Fig. 2 is a top plan view of the nozzle groups and grids;

F i g. 3 is another embodiment of an arrangement according to the invention in cross section.

The beets arrive at point 1 at the beginning of the washing device on a grate 2, from which the Any remaining water and loose dirt particles fall into the collecting container 3. For transportation the beets are served by an endless, wide belt 4, which is guided over rollers 5 and is normal to the belt surface and has transverse walls 6 which extend transversely to the direction of movement and which grasp the beets and run it over the grate. After the beets have been guided over the first grate zone 2, they slide via the first group of nozzles 7 and are intensely splashed with water from below and swirled around. Due to the large number of nozzles and their spatial concentration, only a relatively low water pressure is required, to whirl up and circulate the laundry. The distance from the bottom of the tape to the The grate surface is preferably so large that the beets are not hindered in their rolling movement. In the further course of the washing process, the beets reach a grate 8 through the water and dirt flow off and get into the collecting container 3. The grate 8 is followed by a next one Nozzle group 9 with an associated grate section 10. A similar one is repeated here Washing process, whereby beets that have been cleaned of the coarsest dirt reach this washing zone, which therefore pollute the washing water relatively little. Located under this grate a collecting container 11, from which the water

ίο routed to the nozzle group 7 via a pumping system will.

The second washing zone is followed by a third washing zone of the same type with the group of nozzles 12, the grate section 13 and the collecting container 14. The nozzle group 12 is supplied with fresh water. The relatively clean water that runs off through the grate 13 is stored in the container 14 collected and pumped to the nozzle group 9, from whose nozzles it exits under pressure. After leaving of the grate 13, the beets reach the ejection 15, which is designed here as an inclined plane, on which the beets slide along.

From Fig. 2 shows how nozzle groups and grate bases alternate one behind the other in the direction of movement are arranged. The nozzles are preferably a few centimeters apart, and the grids should have spaces between them so wide that the water can flow off unhindered However, laundry cannot fall through.

F i g. 3 shows another embodiment of the arrangement according to the invention, in which the grate bottom 16 consists of continuous bars that are not is interrupted by any nozzle groups. The nozzles are rather in groups on pipes 17, 18, 19 arranged below the grate 16. In the embodiment shown, there are three rows of Nozzle pipes 17,18,19 with each other, the lower tubes 19 are each arranged on the gap of the upper, so that the emerging from the nozzles Water can hit the beets without obstruction.
