DD217723A1 - WASHING DEVICE FOR DIFFERENTLY MOLDED CONTAINERS, ESPECIALLY 200 L UNIT WAGONS - Google Patents

Abstract

This washing device for containers of various shapes, in particular 200-liter unit wagons, is characterized by the fact that a rotating pipe system equipped with flat-jet ducts is inevitably guided so that the flat-jet ducts always have the same distance to the container surface to be cleaned in or around the container during their circulation Have beam direction. For this purpose, the pipe system supporting the flat jet ducts is guided by means of a guide track, which is adapted to the container shape, to the container shape.

Washing device for containers of different shapes, in particular 200 l units

Field of application of the invention

The invention relates to a washing device for containers of various shapes, in particular for 200 l unit wagons, as used in slaughterhouses, in meat processing plants, commercial kitchens and industrial plants. This is the application of spray jet technology.

Characteristic of the known technical solutions,

There are Was.chvorrichtungori for differently shaped containers, so; iuch liii ΖΟΟΊ-Einhuilswayvit bokunnl. The cleaning process is carried out either by rotating brushes or by spray nozzles by means of pressurized water.

In order to keep the number of spray nozzles within reasonable limits, these are designed as jet nozzles. These form a fanned water jet, wherein the beam angle should not exceed a certain size, so that in the edge region, the beam intensity and thus the cleaning effect are still sufficient. This implies that the distance between the nozzles must be as optimal as possible with respect to the fan sheds and in the area to be cleaned.

From a number of methods and devices it is known that the required orbital motion is carried out by the spray nozzle device and its movement is either inevitably by mechanical means or also based on the recoil principle. The latter form has the disadvantage that the cleaning effect is different, since the orbital motion of the spray nozzle device is affected in a modified recoil.

In a known washing machine for washing standard meat trolleys, the nozzles are reciprocated in front of a displaceable frame parallel to the outer surfaces to be washed, and inevitably guided on a circular path by a rotating pipe system for washing the four inner surfaces and the bottom.

The washer therefore has the disadvantage that, on the one hand, the optimum cleaning distance remains constant due to the frame equipped with nozzles, but the number of nozzles is not minimal due to their arrangement in a closed frame and, on the other hand, the number of nozzles equipped with nozzles only rotating the nozzles must be designed for the least cleaning distance, d. H. not minimal is.t and also the optimal cleaning distance

in one revolution z. B, in the corners is not respected. .

Object of the invention. -

The aim of the invention is to eliminate the disadvantages described, therefore to find a device in which achieved with minimal use of nozzles and their arrangement a uniformly good cleaning effect and thus the performance of the washing device is increased. ,.

Explanation of the essence of the invention

According to the invention this is achieved in that on a rotatably mounted hub two tubes equipped with flat jet nozzles are slidably arranged so that in a revolution of the hub, the entire, to be cleaned container surface, with always the same distance of the flat jet nozzles in the beam direction to the container surface is directly irradiated , For this purpose, a rigid tube is fixed to the hub, on which a displaceable distributor with the branching nozzle-carrying tubes is arranged so that it over a role, which runs in a guideway which corresponds to the container shape, the container shape is trackable. The flat jet nozzles are now arranged on the nozzle-carrying tubes so that the water jets impinge in a line on the container surface, wherein in each revolution of the tube system, the entire container surface to be washed is directly irradiated. As a result of the nozzle-carrying tubes which track the container shape, the distance between the flat-jet nozzles and the container surface in the jet direction is kept constant in each position during the circulation of the pipe system. In addition, the coverage of the flat jets is not changed, so that a uniformly good cleaning effect can be achieved. The feeding of the washing liquid to the nozzles takes place from the hub via the rigid pipe, the distributor to the nozzle-carrying pipes attached thereto. According to the invention, the feeding of the washing liquid from the hub to the nozzle-carrying pipes can also be effected by means of flexible hose line.

Embodiments'

The invention will be explained in more detail below with reference to an embodiment.

It show the,.

Figure 1 is a view of the essential part of the invention for the washing device, shown with container in a rectangular shape without bottom, so that the parts behind it are visible, the pipe system is shown in dashed lines in its 2.Extremlage.

FIG. 2 shows a section along the line A - A according to FIG.

On a rotatably mounted hub 1, which serves in a known manner as a fulcrum for a pipe system 2, the latter is arranged and designed so that in a rotation of the hub 1 with the pipe system 2, the entire surface to be cleaned container, in the embodiment, all the inner surfaces and the outer side wall surfaces of the container, can be directly irradiated by the flat jets 4 of the flat jet nozzles 5. For this purpose, a rigid tube 6 is fixed to the hub 1 and arranged on this a displaceable manifold 8 with the branching nozzle-carrying tubes 7 so that this by means of a roller 9, which corresponds to a guide rail 10 which corresponds to the container mold 11 runs, the container mold 11 is trackable. The flat jet nozzles 5 are now arranged such that the flat jets 4 impinge in a line on the container surface 3, wherein in each Urhdrehung of the pipe system 2, the entire surface to be washed container 3 is irradiated directly. The supply of the washing liquid from the hub 1 to the nozzle-carrying tubes 7 'via the rigid tube 6 and the manifold 8.
