Description

EQUIPMENT FOR WASTE CLEANING AND SIMILAR METHOD

The invention relates to apparatus for washing a waste container comprising: 5 - a washing space in which at least one empty waste container is arranged to be washed, - washing means adapted for washing at least one waste container at desired locations with washing jets comprising at least one waste container arranged in longitudinal direction; a rotary shower jet having a plurality of asymmetrically disposed nozzles for forming a jet and a transfer mechanism for adjusting the waste container to be moved inside the wash area to and from the wash area.

Further, the invention also relates to a corresponding method.

Various devices known in the art are, for example, washing equipment for waste containers arranged in vehicles. In such cases, the bin is washed using brushes and showers. In addition to brush-based devices, shower-based devices are also known. Laundry equipment can be used to wash the bin inside and out. In particular, 25 biowaste containers require washing, as the waste they collect is easily trapped and their contamination can cause significant health and hygiene problems.

However, prior art hardware has a number of unresolved problems. For example, washing biowaste containers c is really challenging to achieve an acceptable washing result Q_0. Especially in the collar of the bio-waste container, both inside and outside the mouth, for example, the bio-waste container ...

o When filling the road with dirt which, when dried, sticks to the collar 00 35 with extraordinary stubbornness. Known washing machines are capable of satisfactorily washing the container in other respects, 2 but there is much to be desired in the collar performance in particular.

5 waste bins of different size and shape also cause their own problems. The same equipment should be able to achieve good washing results regardless of the size and shape of the dishes, as the size and shape of the dishes on the car wash path may vary greatly. Specifically, the variation in the shape of the containers has made it difficult to wash the collar of the container, whereby prior art devices require separate mechanisms for containers of different sizes and shapes. This, in turn, complicates the appliance and introduces new steps to the washing process. In addition, recycling several washing machines along the same route is not economically viable.

15

Also, prior art deck cleaning solutions leave much to be desired with regard to the washing result. The lid of the pan gets dirty almost as much as its collar. The mechanisms of movement of the containers in the devices have been complicated in structure. Emotions include the various lifters that hang the container in its holders. Doing so may cause the dish to behave in a nonchalant manner during washing.

It is an object of the present invention to provide a more efficient apparatus for washing the waste container to be achieved

£ 30 o In the invention, the collar portion of the waste container is adapted to be washed with at least one rotating wash jet member. The rotating shower jet element provides a surprisingly powerful washing effect, whereby no mechanical abrasion is required at all.

According to one embodiment, the rotary washing shower member is adapted to wash the collar portion of the waste bin from outside the mouth of the waste bin. In this case, the rotating shower jet is particularly effective at cleaning the collar portion of the waste container. Surprisingly, and revolutionary with regard to preconceptions 5, there is no need for the shower jet to be inside the container, but the shower jet acting from the outside has the most effective washing effect. From the outside, the washing jet that whips the collar area of the container over the collar area extends to the inside of the container as well as to the end square portion. In addition, the angle of contact between the shower jet formed by the rotating nozzle and the portion of the dish to be washed varies during washing. In this case, the washing jet strikes the collar portion of the vessel at one of its positions relative to the vessel at several angles, which contributes to a more effective washing effect that removes dirt.

In one embodiment, there can be at least two rotating shower jets adjacent to each other. In this case, the distance between the shower jets can be, for example, 450 mm to 800 mm, more particularly 550 to 20 mm to 700 mm. Surprisingly, such an arrangement can wash up to two waste bins at a time throughout, or alternatively, one large waste bin that is washed by both washers. In addition to the collar portion, the washing nozzles can also wash the inside of the waste bin, thereby allowing multiple dishwasher parts to be washed with the same rotating wash jet heater. This will simplify the design of the hardware and make it mobile

According to one embodiment, the waste container is adapted to be flanked by a tumble anterior flange in the direction of the washing nozzles for washing the collar. The gently sloping front opening can already be realized so that the mouth of the container is in the lower position o with respect to the bottom. In this case, the waste bin is in a favorable position for many

in relation to. Now all the washing liquid and dirt will surely drain out of the inside of 35 containers. On the other hand, the inner surface of the container is also flushed with the washing liquid flowing from the bottom towards the mouth. In addition, the 4 waste bins can rest entirely on one side of the bin on the conveyor. This page may be a hinge page for the waste bin lid. This will ensure that the lid of the waste bin will remain open and will not close, for example, during washing.

Other advantages and further embodiments of the invention will be described below in connection with the application examples.

washing jets 14.1 to 14.3 are provided for washing at least one of the waste containers 10 35 at desired locations 15.1 to 15.7 (Figures 6a and 6b). The apparatus is arranged, for example, inside a wash room 12 fitted to a truck 11 5, where the washing means 19.1 to 19.3 operate during washing.

The washroom 12 with its hardware may be fixedly mounted on the car body 11 according to one embodiment. According to another embodiment, space 12 with its hardware may also be of module type. The washing container can then be dropped off the base of the car 11, whereby it can be left in its place where it can serve as a fixed washing station. The car 11 is then released for other uses.

Figure 1 shows an embodiment of the apparatus according to the invention when viewed from the rear of the car 11. The washroom 12 may be otherwise an enclosed space, but is accessible through an opening 16 in the rear wall 13 of the car 11 15 from where the container 10 can be moved in and out of the washroom 12. The aperture 16 can be closed by an opening door, a movable rear curtain 17 which prevents water and hot steam from splashing out of the otherwise enclosed washroom 12. In Figs. 1 20 to 5, the blind curtain 17 is upwardly within the washroom 12. The rear curtain may also be fabric-like instead of veneer-like, whereby it is flexible and has movable edges between the arrangement 16 covering the opening 16 in the rear wall 13 and the roof 12.3 of the washroom 12. With the rear cover 25, the washroom 12 of the washroom 12 is sufficiently tight. As a result, containers 10 can be safely operated, for example, in urban conditions

sl-£ 30 Inside the washing space 12 are provided handling means for the container 10, such as, for example, a moving mechanism 18 o tn acting as a moving means and a washing means 19.1 - 19.3 with supporting and moving means.

At least some of the detergents 19.1 to 19.3 may be within space 12

(M

fit for movement. The movement of the means 19.1 to 19.3 may occur with respect to the space 12 and / or the vessel 10. The washing means 19.1 to 19.3 and the moving means 18 of the container 10 are in the washing space 12 so that the 6 empty containers 10 can be washed both inside and outside.

In the case of the embodiment 5, the container 10 is moved by the dish lift 18. The already empty waste container 10 is driven into the washing space 12 by the conveyor 18 for washing the jets 14.1 to 14.3 for washing the container as well as after the washing. The dish elevator 18 may consist of guides 18.1, 18.2 disposed adjacent to the floor 20 of the washroom 12 and adjacent to both side walls 12.1, 12.2 (Figures 2-4). Between the guides 18.1, 18.2 there is provided a carriage 20 arranged in the longitudinal direction of the car 11 and in this case to some extent also in the vertical direction, the carriage 20 having gripping means 21 for securing the receptacle 10 to the carriage 20. The carriage 20 may be formed by pneumatic suction cups 21. so that the container 10 can rest on one side of the principal in its entirety in the tray 20.

The washing means consist of movable nozzle rods 28 arranged in connection with both side walls 12.1, 12.2 and the roof 12.3 of the wash room 12 and having a plurality of washing nozzles 27.2, 27.3 fitted thereon. With this external scrub ramp 19.2, 19.3, the waste container 10 can be washed externally 15.3, 15.4 on at least three of its sides. In ceiling 12.3, the washing nozzles 27.3 are suspended from the rod 28

? met 27.3 are free to swing as the roof bar 28 is moved.

I 30 o The side nozzles 27.2 are directly integrated into the side rods 28.

LO

in Wash nozzles 27.2, 27.3 are at a distance o apart in vertical bars 28. According to one embodiment, the distances can be, for example, 150 mm to 250 mm, more particularly 200 mm to 220 mm, such as 210 mm. One example of a commercial supplier of ramp nozzles 27.2, 27.3 is Spraying systems Co. The roof bar 7 and the side bars 28 can form at their ends a matched structure, whereby they move in the washroom 12 in the same line at all times. In this case, it is sufficient for the ceiling 12.3 of the wash room 12 to have guides 29 arranged close to the walls 12.1, 12.2 for the rod structure 28. The rod structure 28 may be chain-driven 22 '. The solution is surprisingly simple in construction and workable.

According to one embodiment, the position of the vertical bars 28 forming the outer wash ramp can also be changed in the width direction of the wash room 12. Thus, for example, one of the vertical bars may be driven from its position adjacent to the wall 12.2 of the wash room 12 to the side wall of the narrow dishwasher to be washed and back to the wall 12.2 of the wash room 12.

15

The wash chamber 12 is provided with a movable and, surprisingly, rotating nozzle assembly 19.1 on its front wall 23 for washing the container 10 from the inside 15.2, 15.7 and the open end, or mouth 15.1. The use of the rotary washing nozzle head 19.1 for washing the collar 15.1 of the container 20 is ingenious because the size and shape of the containers is so diverse at present. The use of the rotating nozzle head 19.1 simplifies the washing process and simplifies the construction of the device. Now, the arrangement 19.1 comprises two spaced apart nozzle heads 25.1, 25.2 which are shown in Figures 2 and 5. The wash nozzle heads 25.1, 25.2 are rotatable. The rotational motion may be caused by the pressure washer being discharged from the nozzles. One commercial supplier example of such an indoor scrub nozzle 25.1, 25.2 is Bolondi.

sfr x £ 30 Figure 5 shows the wash nozzle 25.1, 25.2 in greater detail. For example, the nozzle head 25.1, 25.2 of the washing nozzle 0 may consist of four nozzles 00 S 27.1 which are provided with a circular caliper 26 of a spherical nozzle head 25.1, 25.2. The circular caliper 26 rotates about its center.

(M

In addition, the nozzle head 25.1, 25.2 itself rotates. In this case, only 1 few nozzles 27.1 provide a full-space wash jet 14.1. More generally, the nozzles 27.1 may have, for example, two to four wash heads 25.1, 25.2.

The nozzle ends 25.1, 25.2 5 causing the rotating wash jets 14.1 may be in a telescopic shaft 24 which enters the wash space 12 through its front wall 23. With the nozzle heads 25.1, 25.2 in contact with the front wall 23, the arms 24 are retracted, i.e., the wash jet members 25.1, 25.2 are outside the vessel 10 to be located substantially in the machine front 38 of the car 11, between the cab space and the wash room 12. Hereby, the car 11 is advantageously short because its effective load space can be utilized very efficiently. Machine space 38 is provided with means for pressurizing and heating the washing liquid and for generating propulsion of the moving parts of the apparatus 15. The apparatus according to the embodiment may have, for example, one water pump for washing the vessel 10. One example of its editor is Pratissoli. Of course, there can be more than one water pump.

Figure 2 shows the apparatus according to the invention in the front wall 23 of the car 11 in slightly more detail and Figure 3 shows the right side of the apparatus and Figure 4 the left side of the apparatus obliquely from the rear. As can be seen from the figures, the carriage 20 may be chain driven, for which the guides 25 18.1, 18.2 are provided with a chain wheel 22.1 to 22.3 to allow the passage of the chain 22. At the end 23 of the front wall 23 of the wash room 12 there may be supports 35 for supporting the lid 37 of the container 10. In addition

LO

there may be stops 30 at the end that prevent the lid 37 from rising during a 3-wash, as the lid 37 is washed from the bottom to the bottom-30.

The path of the container 10 in the washroom 12 may be slightly downhill.

h- · o In this case, the container 10 is in its washing position on its side with a slight front

(M

in the direction of the wash nozzles 14.1 such that its mouth 35 15.1 is lower than the bottom 15.6. The keno position is achieved, for example, by the height difference 9 of the guide rails 18.1, 18.2 of the moving means. In this case, the container 10 will always rest on its side 20 with its carriage 20 and will not need to be particularly supported. The side on which the receptacle 10 rests on the carriage 20 is the hinge page 15 of the lid 37 of the receptacle 10. As a result, the lid 37 of the waste container 10 remains self-powered 5 open. The front canopy of the container 10 need not be very large, but an angle of up to 10-20 degrees is sufficient.

In the vicinity of the front wall 23 of the wash room 12, there may be associated with the sidewall 12.2, positioning means for positioning the container 10 in the wash room 12. The positioning means may consist, for example, of at least one inductive sensor 31. The inductive sensor 31 can, for example, detect the metal of the dish elevator 18. The inductive-15 sensor 31 provides certainty of location recognition under difficult conditions such as those prevailing in the dark and humid washroom 12 during, before, and after washing. In principle, positioning means may consist of other principles-based means, such as a photocell, for example.

In Figure 5, the inner washing nozzles 25.1, 25.2 are inserted into the washing space 12, whereby their arms 24 are also visible. The projection angle of the arms 24 relative to the rear wall 23 of the washroom 12 may be of the same order of magnitude as the inclination of the guides 18.1, 18.2.

In this case, the arms 24 are approximately parallel to the longitudinal direction of the vessel 10 ^. The front wall 23 of the wash room 12 may have a tn? a common panel 33 for the passages 32 of the nozzle arms 24, which may also include disinfectant nozzles 34. The distance between the washing heads xg 30 25.1, 25.2 may be, for example, 450 mm to 800 mm, more particularly 550 mm to 700 mm, e.g. S in Figure 7b).

CM

The relative position of waste bin 10, 10 'and wash jet members 25.1, 25.2 relative to one another can be varied, for example, on a country or customer basis. In this way, it is possible to wash the waste containers 10, 10 10 'independently of the container size. According to one embodiment, the position of the washing heads 25.1, 25.2 relative to each other and to the receptacles to be washed therein can be adjusted so that the device can wash the desired range of receptacles, which may have receptacles of widely differing dimensions and shapes. To this end, the angle of the arms 24 in panel 33 may be varied, as well as the projection of the wash heads 25.1, 25.2 into the wash space 12 and the position relative to the dishes to be washed. In fact, the position of the washing means 19.1, 19.2 with the rotary washing head 25.1, 25.2 10 is quite freely adjustable, which is made possible, for example, by adapting the panel 33 to each arrangement.

Another way of adapting the device to various container sizes 15, which can be applied in addition to or even instead of changing the position of the arms 24, is through changes to the container elevator 18. For example, if the non-standard container does not engage the fasteners of the container elevator 18, the gripping pins 39 (FIGS. 1 and 3) of the container elevator 18, which are positioned below the collar 15.1 of the container 10, may be displaced laterally. If the spikes 39, for example, hit the stiffening ribs of the collar 15.1 of the receptacle 10, then by moving them laterally they are suitably set aside so that the spikes 39 fall below the collar 15.1.

The dish lift 18 can also be stopped in the wash room x 30 12 earlier than the normal position, i.e. the container 10 is not moved as deep 0 into the wash room 12 as normal. The wash room 12, which is made surprisingly accessible by the rotating wash jets 25.1, 25.2, can also be subsequently retrofitted with nozzles which

Figures 6a and 6b show a rough plan view of the container 10 being machine-washable rear and side view. Washing can be done in stages. The sequential steps may be, for example, internal washing of the container 10, external cleaning and external cleaning of the lid 37 5. The steps may also overlap partially. In addition, washing of the network filter can be performed at intervals.

During the internal washing of the container 10, the collar portion 15.1 of the waste container 10 and the inside surface of the lid 37, which points upwards in Fig. 6b, are also washed.

The following is a description of the various washing programs of the apparatus, which in this case are two. In the method for washing the waste container 10 according to the invention, the at least one waste container 10 15 is washed in the wash room 12 with wash jets 14.1 to 14.3 from the desired positions 15.1 to 15.5.

During each wash, the tray 20 is driven (unless already for example after washing the previous container) in the guides 18.1, 20 18.2 out of the rear opening 16 of the washroom 12, the tray 20 then descends quite close to the ground and the tray 10 can be secured there . The receptacle 10 is moved against the suction cups 21 and the suction cups 21 engage on the flank side 15 of the lid 37 of the receptacle 10. The carriage 20 of the dish elevator 18 25 has at least one open and already empty receptacle 10 cvj ^ inserted into the wash room 12 above the cover 37 in the area of influence of the wash jets 14.1 - 14.3. In addition, the container 10 is driven in slightly

LO

? downhill. This way the lid 37 can be washed on both sides and does not cover the outer wall 15.5 of the container 10.

I 30 o The first of these programs is the so-called quick wash. When the rear curtain 17 has lowered and the container 12 has been driven by carriage 20

Is on its side, sleeping the washroom 12 near the front wall 23

(M

(this is identified by a sensor 31 which is targeted to identify the ground 35, for example the carriage 20 of the dish lift 18), the washing nozzle 25.1 protruding from the front wall 23 of the washroom 12 leaves to wash the inside of the dish 10 12 15.2, 15.7. The nozzle 25.1 extends from the minus position outside the receptacle 10 (perpendicular distance e.g. 300 mm to 700 mm, more particularly 400 mm to 600 mm, such as 500 mm from the collar 15.1 of receptacle 10) into receptacle 10 inwardly 5 of actuating means such as telescopic hydraulic cylinder rod 24 Moved by. After reaching the internal limit, i.e. the nozzle 25.1, for example, at a distance from the bottom 15.7 of the container 10, the internal cleaning of the container 10 stops and the external cleaning begins.

The nozzle 25.1 does not necessarily need to run even to the bottom 15.7 of the vessel 10, but its extreme position within the vessel 10 may be, for example, 300 to 700 mm, more particularly 400 to 600 mm from the bottom 15.7 of the vessel 10. The inner nozzles 25.1, 25.2 return to the outside of the container 10 without being washed 15. The outer wash ramp 19.2, 19.3 washes the container 10 back and forth, for example for about 10 seconds, by moving the guides 29 on the roof boundary 12.3. The lid is cleaned while the container 10 is moving towards the rear opening 16 of the wash room 12.

20

One of the programs may be the so-called normal wash. In a similar manner to the quick wash, the wash nozzle 25.1 starts to wash the inside 15.2 of the container 10 when the rear curtain 17 has lowered. The washing nozzle 25.1 leaves the minus position from outside the receptacle 10 and protrudes into the receptacle 10, moved by the hydraulic cylinder arm 24. After reaching the inside limit, the washing nozzle 25.1 stops for about two seconds and washes the dish 10 m? on July 15th. The washing nozzle 25.1 then moves back to its minus position outside the container 10 and washes the movement

X

g 30 during the inside of the container 10.

00 tn While outside the receptacle 10, the at least one rotating washer nozzle head 25.1 is further washing the collar 15.1 of the receptacle 10. This situation-

CM

it is illustrated in Figure 6b. This position may be the extreme position of the washing nozzle 25.1 35 with its bar 24 retracted at least partially into the machine compartment 38. An example of a position of the washing nozzle 25.1 washing the collar 13 15.1 may be about 500 mm long, outside of container 10. The position of the nozzle head 25.1 with respect to the cross-section of the vessel 10 is not quite in the middle of the vessel 10. Because of the varying vessel sizes washed by the apparatus, the nozzle head 25.1 is surprisingly positioned to accommodate all Examples of the position of the nozzle head 25.1, 25.2 with respect to different vessel sizes are given below.

Referring to Figures 7a and 7b, some distance information is shown when washing dishes of different dimensions. For example, when washing a 120 L dish according to Figure 7a, the distance dx 15 from the front wall 15.4 of the nozzle head 25.1 is almost non-existent. Thus, the nozzle end 25.1 may be close to the touching distance from the front wall 15.4 of the container 10. Horizontally (d2), the nozzle end 25.1 may be located approximately on the center line of the vessel. The distance d3 depends on the container manufacturer.

In the case of a 240 L container, which is a basic container for bio-waste, the nozzle end 25.1 may be approximately at the center of the container.

Figure 7b shows a 600 L container 10 'which is the most common 4-wheel container. Therein, the nozzle ends 25.1, 25.2 are vertically (dx) in the middle of the vessel 10 '. Horizontally, the distance (d?) Of the nozzle heads ^ 25.1, 25.2 from the side wall of the vessel 10 'may be θεί ο ^ to be about 200 mm. Distance between nozzle heads 25.1, 25.2 (d3)

LO

? for example, the back wall 15.5 of the container 10 '(i.e. the wall to which the lid 37 is secured) may be approximately 350 mm.

£ 30 0 After the internal and collar wash, the inner cleaning of the container 10 will end and the external cleaning of S will begin. The outdoor wash ramp 19.2, 19.3 washes the dish 10 o back and forth for about 10 seconds. After the given washing time

CM

the outer cleaning ends and the rear curtain 17 rises, after which the 35 starts cleaning the cover 37. Washing of the lid 37 from its inner surface occurs at the same time as the receptacle 10 moves towards the rear wall 13 of the wash room 12 and is surprisingly performed by the same washing head 25.1 with which the receptacle 10 was washed from the inside. The cover 37 is washed from its outer surface by a separate washing nozzle ramp, which may be fixed or movable. The outer scrub ramp of the cover 37 is located adjacent to the floor 20 of the washer 5, 12, between the rails 18.1, 18.2 (not shown). Finally, in both washes, the dish elevator 20 is automatically driven out of the washroom and the washed dish 10 is removed from the suction cups 21 of the elevator 20. The lid 37 is also very clean by the invention.

10

Next, the washing of the collar 15.1 of the container 10 will be explained in more detail. The known waste dishwashing facilities have not had any functional washing of the collar 15.1, nor any functional cleaning of the inner surface of the cover 37. In the apparatus 15 according to the invention, collar and lid cleaning is surprisingly carried out with the same rotating nozzle head 25.1, 25.2 as the inner washing of the container 10. This is possible because the inner washer nozzle head 25.1, 25.2 rotates and washes vessel 10 with pressurized water jets 14.1, such as 85 bar / 150 rpm. The more commonly used pressure 20 may be, for example, 50 bar to 120 bar, but pilot phase studies have also found that pressure above 100 bar no longer significantly improves washing performance. The utilization of such high pressures is made possible by sufficient recycling and purification of the wash water.

25

The recycling and purification apparatus may, for example, be known per se. One example of this is initially coarse filtration with a mesh filter followed by fine mesh filtration using multiple sand filter mattresses. According to one embodiment of g 30, the sand filtration may have, for example, o three layers of quartz sand, where the crystal sizes are, for example, from 3 to 5 mm, 2 to 3 mm and 1 to 2 mm. These may be preceded by a hydroanthic filtrate layer, where the crystal size may be, for example, 1.4

CM

- 2.5 mm. In such a purification system, the washing water 1 is made clear and at the same time the microparticles are filtered out of it, whereby the high pressure nozzles 27.1 can be used in the rotary washing nozzle 25.1, 25.2.

The movement path of the inner washer nozzle 25.1, 25.2 in the longitudinal direction 5 of the car 11 is, for example, 1000 mm in the embodiment. The nozzle 25.1, 25.2 runs deep inside the vessel 10 to wash the inner surfaces 15.2 of the vessel 10 and its bottom 15.7 (e.g. 400 to 600 mm from the bottom 15.7 of the vessel 10). The collar 15.1 and the inner surface of the cover 37 are cleaned when the pressure nozzle 25.1, 25.2 of the washing nozzle 25.1, 25.2 spray the collar 15.1 in a suitable arrangement.

More particularly, the position of the rotary washing nozzle 25.1, 25.2 is then surprisingly outside the container 10 and its mouth 15.1. Then the washing jets 14.1, or at least most of them, hit the collar 15.1 of the vessel 10 at several angles. Because one of the rotating washing heads 25.1, 25.2 may have, for example, four nozzles 27.1 disposed asymmetrically with respect to each other and since the nozzles 27.1 are moved in two dimensions, the junction angle of the jets 14.1 and the collar 15.1 of vessel 10 particularly effective in cleaning the shower 14.1. In addition, such a wide-ranging shower jet 14.1 allows the collar of jet 14.1 to accommodate collars of multiple sized containers, whereby multiple jet containers can be washed with the same jet assembly. When hitting 25 collars 15.1 at multiple angles, the pressure water is particularly effective

largely during washing. The Applicant has made a remarkable and even 35 surprising finding that when the jets 14.1 hit the collar 15.1 of the container 10 at a too slight angle, the washing result of the collar 16 15.1 is unsatisfactory. On the other hand, it has also been found that the washing jet that hits the collar 15.1 too stiffly bounces back and does not produce the desired washing result. A shower jet 5 14.1 directly on the collar 15.1 with a tilting jet angle ensures the best washing results.

The actuating apparatus for the nozzles 25.1, 25.2 and the water hoses are protected in the pump room 38 at the front of the car 11. In addition to the nozzles 25.1, 25.2, the in addition to being simple.

In the apparatus according to the embodiment, for example, one large dish (size 600 - 1100 l) or two smaller dishes (size 120 - 330 l) can be washed at a time. When washing a smaller container, only one washing nozzle end 25.1 is used and, in the case of a larger container, both washing heads 25.1, 25.2. With one and the same apparatus according to the invention, it is surprisingly possible to wash the collars of vessels of widely differing physical dimensions. Washing of vessels of different sizes can be carried out even sequentially. For example, dish sizes from 120 l to 1100 l can be washed with the same equipment, the physical dimensions of which vary greatly. In addition to the bio-waste container, other containers, such as dry waste containers and recycling bin o, can also be washed.
