EP3603828B1 - High pressure cleaning device for dirty components - Google Patents

Description

The invention relates to a high-pressure cleaning device for soiled components, for example series parts. It relates in particular to the cleaning of components from the chemical industry and in this connection from the refinery sector.

High pressure is understood to mean a pressure of the cleaning fluid used of at least 500 bar. Water is preferably used as the cleaning fluid. At the high pressure values, the water jets emerging from a nozzle have such a high impulse that they mechanically remove contaminants from the components. It is worked with water without additives, in any case, additives are avoided as far as possible. It is possible that cleaning additives, for example grinding media or sand, are added to the water, but this has a disadvantage because, for example, grinding media and sand further reduce the already short service life of the nozzles.

The water jets emerging from the nozzles should hit the components to be cleaned directly. The distance between nozzle and component should be in the range of 5-20, preferably 7-10 cm, in this area the water jet has its highest momentum. If the distance is greater, it increasingly loses energy; if the distance is shorter, it is not sufficiently developed.

Examples of the components to be cleaned are bells from distillation plants, pipe sections, plate heat exchangers, grids, grates, rods, plates, etc. dirty like that. The components can be contaminated, for example from nuclear power plants.

The ones from the DE 31 41 516 A1 known high-pressure cleaning device has a grid table on which the components to be cleaned rest. A nozzle arrangement rotatable about a vertical axis overlaps this grid table from above. Operational If water jets emerge downwards, they hit the components directly. The nozzle arrangement is fixed to a support arm and is rotated by a rotary motor. The support arm is arranged longitudinally adjustable by a motor on a longitudinal beam. The longitudinal beam is aligned, for example, parallel to the lattice table. In this way, the nozzle arrangement can be moved over the stationary components to be cleaned during operation.

Since the water jet emerges from the nozzle at high pressure, there is, on the one hand, a considerable back pulse and, on the other hand, the risk of industrial accidents is high. It is therefore desirable that the cleaning process is as automatic as possible. An operator should be at a sufficient distance from the water jets and / or be adequately protected. If possible, the nozzles should not be guided by hand, as is still the case today, but by means of a device. In this way, physical labor is also reduced.

Out EP 3 1240 720 A1 a high-pressure cleaning device for soiled components is known in which the component to be cleaned is stationary. A nozzle from which a high pressure water jet emerges can be aligned as required using an adjustment device. It is controlled by an operator who sits in a closed cabin that is connected to the nozzle and can be moved lengthways along rails.

The object of the invention is to improve the known devices and to specify a device which independently carries out the cleaning process. This object is achieved by a high-pressure cleaning device for soiled components, in particular components from chemical plants and preferably plants in the oil industry,

• with a pressure of a cleaning fluid used of at least 500 bar,
• with a frame,
• with an endless conveyor belt arranged in the frame, which is guided around deflection rollers, each of which has a horizontal axis of rotation and to which a front deflection roller and a rear deflection roller belong, one upper run on which the soiled components are located during operation, and one Forms the lower run, and which has a large number of passages,
• with an entry station, which is located near the front pulley and has an entry table that is essentially flush with the upper run,
• with an exit station, which is located near the rear pulley and has an exit table,
• with an upper nozzle arrangement which is arranged above the upper run, which is rotatable about a vertical axis of rotation and has downwardly directed nozzles onto the upper run, and
• with a lower nozzle arrangement, which is arranged between the upper run and the lower run, which is rotatable about a vertical axis of rotation and has nozzles directed upwards towards the passages,
• whereby the upper run is covered by a hood between the entrance station and the closest nozzle arrangement and this hood is so long that a person cannot reach as far as the nozzle arrangement, and the precautions are also taken in the area of the exit station.

In operation, the components to be cleaned are on the upper run. They are placed on the upper run from the entrance table, where they can be temporarily stored. This is usually done by an employee, but can also be done by a robot. The conveyor belt runs continuously and thus conveys the components continuously. After a certain conveying distance on the upper run, a component to be cleaned comes into the area above the lower nozzle arrangement and is cleaned there from below. Only those water jets come into contact with the respective component that can pass through the passages. So that the components are not lifted too much by the water jets, they are advantageously held down. For this purpose, a hold-down device is preferably provided, which is located slightly above the soiled components.

The component to be cleaned then comes into the area below the upper nozzle arrangement and is cleaned from above there. After another conveyor section, the component arrives near the rear deflection roller, where it is removed from the upper run and can be temporarily stored on the exit table.

The device is located in a housing that is only open in the area of the entrance station and the exit station. If the distance between an opening in the entrance station and the nozzle arrangement closest to it is chosen so large that it is sufficiently longer than the arm of a person, it is not possible that a person can be injured even if he reaches into the housing from the entrance station. The same applies to the conditions at the starting point. This means that the cleaning takes place in an area that is inaccessible to humans. People cannot be injured in this way.

The speed of the conveyor belt, the pressure and the amount of water ejected by the nozzle arrangements, the orientation of the nozzles and their number, the size of the passages and their proportion of the area of the conveyor belt can each be selected largely independently of one another so that for a specific Cleaning task, a good cleaning result is achieved in each case.

The lower nozzle arrangement is located between the upper run and the lower run. Further deflection rollers are preferably provided below the front deflection roller and the rear deflection roller, in particular at least two lower deflection rollers. These pulleys also have a horizontal axis of rotation. This creates more space. The lower run is deflected far down and has a distance from the upper run that is greater than twice the diameter of a deflection pulley. All pulleys can be identical. At least the rear and front deflection rollers are preferably identical in construction.

The conveyor belt has as large a proportion of the area as possible that is taken up by the passages. In other words, the conveyor belt should be as permeable or open as possible. The passages should make up at least 50% of the area of the conveyor belt, preferably at least 70% and in particular even more. However, the individual passages must not be so large that small components could fall through them. However, this can be counteracted by providing a component carrier on which the components to be cleaned are arranged and are placed on the upper run together with the component carrier. A component carrier makes it possible to select a very open structure for the conveyor belt, for example to provide only individual rods that run transversely to the conveying capacity and are a few centimeters apart. The more open the structure of the conveyor belt, the less it hits The lower nozzle assembly blasts the conveyor belt and not, what is actually intended, the components.

The conveyor belt has individual links, these preferably have side parts and spacers. An intermediate piece connects two side parts with each other. This forms a link of the conveyor belt. The left side parts are each connected to one another and the right side parts are each articulated with one another, the joint axes are horizontal and transverse to the conveying direction. The side panels preferably have roles. They slide or run on side rails. The side panels are outside of the direct jets of the nozzle assemblies. Preferably, metal sheets are provided which reach over and / or under the side parts and shade them against the jets from the nozzle arrangements. The intermediate piece comes into direct contact with the water jets from the nozzle arrangements. The passages are located in the area of the intermediate pieces, not the side parts. In one embodiment, the intermediate pieces are each formed by only one rod per link of the conveyor belt. In another embodiment, the intermediate pieces are formed by at least one rod. In a further embodiment, an intermediate piece is formed by a rod, and all rods are encompassed by a wire link belt.

The two nozzle arrangements are preferably separated from one another as seen in the conveying direction. As a result, the water jets from the two nozzle arrangements do not collide with one another and the hold-down device does not interfere. It is possible to provide the nozzle arrangement at the same point in the conveying direction. In the area of the exit station, the upper run leading to the exit station is deflected at the rear deflecting roller. It runs downwards. This creates a gap between the exit table and the upper run, which narrows and draws smaller objects or even a person's hand into it. At this point, a rocker, which is designed in particular as a gravity rocker, is preferably provided, which bridges the gap. If it is only slightly deflected, it comes into the area of a safety switch and the conveyor belt is switched off.

Between the entrance station and the closest nozzle arrangement, the upper run is covered by a hood that belongs to the cover plates. This hood is so long that a person cannot reach as far as the nozzle arrangement. The hood preferably has at least one splash guard which is arranged transversely to the conveying direction. Preferably there are three slat curtains one behind the other. You avoid spray water and spray from the nozzle arrangement from reaching the entrance station. They run transversely to the conveying direction. The provision is also made in the area of the exit station, preferably structurally identical.

A return conveyor belt is preferably located next to the conveyor belt, in particular parallel to it, at the same height and the same length. If it is determined at the exit station that a component has not been adequately cleaned, it is placed on the return conveyor belt, from where it is returned to the entry station.

A gantry crane or a corresponding crane has proven to be advantageous. Its crane beam is located above the entrance station or the exit station. It is used to lift and transport components. This relieves an employee who is at the entrance or exit station. In particular, an electromagnet, for example an electric pot magnet, is suspended from the crane, with which iron components can be connected in a controlled manner. These components can then be lifted, transported and put down using a servo device or balancer.

A right-handed, orthogonal x-y-z coordinate system is used for the description. The positive x-axis runs in a conveying direction 36 of the components 48 to be cleaned. Like the x-axis, the positive y-axis is located in the horizontal plane, it runs transversely to the conveying direction 36. The z-axis follows at right angles and thus vertically above.

The high-pressure cleaning device has a frame 20 which is composed of profile bars. It is made in stainless steel. The frame 20 has cover plates 21 which are attached to the profile rods and completely close off an interior of the frame to the outside, except for an opening in the area of an input station 22 and an opening of an output station 23. The frame 20 with its cover plates 21 forms a housing. In the middle area, the frame 20 forms a collecting trough 24 below. It has a drain connection.

The frame 20 is arranged to be movable on rollers 26. It has pockets running in the y-direction into which the prongs of a forklift truck (not shown) can engage. The frame 20 can thus be moved and shipped, for example loaded onto a truck.

A conveyor belt 28 is arranged in the frame 20. It is powered by a motor. It runs over a front deflection roller 30 and a rear deflection roller 32. They each have an axis of rotation that is parallel to the y-direction, the two axes of rotation are arranged in the x-y plane. The conveyor belt 28 also runs over a deflector and a total of four lower deflecting rollers 34. All deflecting rollers have axes of rotation that are parallel to one another; these each run parallel to the y-direction.

Between the front deflection roller 30 and the rear deflection roller 32, the conveyor belt 28 runs in the conveying direction 36, an upper run 38 of the conveyor belt 28 extends there. Below this upper run 38 there is a lower run 40 If the rear deflecting pulley 32 rotate, the clear distance between the upper run 38 and lower run 40 would essentially be determined by the diameter of the two deflecting pulleys 30, 32. Due to the deflection and the lower deflecting rollers 34, the conveyor belt 28 is deflected downwards to such an extent that the clear distance between the upper run 38 and lower run 40 in the middle area is greater than twice the diameter of a deflecting roller, in particular greater than five times .

The conveyor belt 28 is composed of individual links. Each link has a left side part and a right side part, which are each mechanically connected to one another by an intermediate piece 42. The left side parts of adjacent links are articulated to one another, as are the right side parts of adjacent links. This is known from the prior art.

Fig. 6 shows a short section of the conveyor belt 28, namely a section of the intermediate piece 42. Rods 43, which connect side parts (not shown here) to one another, and a wire link belt 45 which is carried by the rods 43 can be seen. In an alternative, this wire link belt 45 is dispensed with. Then the intermediate pieces are only formed by the rods 43. The conveyor belt 28, namely its intermediate pieces 42, has passages 44. In the embodiment shown, these are defined by the rods 43 and openings of the wire link belt 45. In another embodiment, not shown, they are only defined by the rods 43.

The input station 22 is located in the vicinity of the front deflection roller 30. It includes an input table 46. It has a height which essentially corresponds to the height of the upper run 38. The entrance table 46 is provided with wheels and can therefore be moved. Components 48 to be cleaned are temporarily stored on it and from there placed on the upper run 48.

The output station 23 is constructed accordingly. It is essentially identical in construction to the input station 22. It has an output table 50. Cleaned components are removed from the upper run 38 in the vicinity of the rear deflecting roller 34 and temporarily stored on the output table 50.

The output station 50 also has a rocker 52, see Fig. 5 . It bridges a gap between the upper run 38 in the area of the rear deflecting roller 30 and the output table 50. It can be pivoted about a pivot axis running parallel to the y-axis. If it is deflected, an emergency switch is actuated, whereby the motor of the conveyor belt 28 is stopped.

In the area of the center of the device there is a lower nozzle arrangement 54 and an upper nozzle arrangement 56 arranged one behind the other in the conveying direction 36, see Figs. 3 and 4 . Both can be rotated independently of one another around an axis that is parallel to the z-direction. The lower nozzle arrangement 54 is arranged between upper run 38 and lower run 40. Because of the deflection of the conveyor belt 28 described, there is enough space there for the lower nozzle arrangement 54. This has nozzles oriented upwards, essentially in the positive z-direction. These nozzles send water jets through passages 44 onto the components 48 located on the upper run 38. So that the components 48 are not lifted too far by the impulse of the water jets, there is a zone above the lower nozzle arrangement 54 and above the components 48 Hold-down 58.

The upper nozzle arrangement 56 has nozzles directed downwards onto the upper run 38. An intermediate grid 60 is provided between these nozzles and the soiled components 48 which are located on the conveyor belt 28. This intermediate grid 60 prevents foreign bodies from getting into the rotary area of the upper nozzle arrangement 56.

The intermediate grid 62 and the hold-down device 58 are mechanically connected to one another and together with a device for height adjustment 61 with which their vertical position can be adjusted.

The high-pressure cleaning device also has a return conveyor belt 62. It is located laterally next to the frame 20 and is independent of it. It has an endless belt that wraps around rollers and is motorized. The return conveyor belt 62 has a length in the x direction which essentially corresponds to the length of the upper run 38. It is located at a height which essentially coincides with the height of the upper run 38 and the tables 46, 50. The return conveyor belt 62 conveys in a direction opposite to the conveying direction 36 of the conveyor belt 28. Components 48 that have not been properly cleaned can be placed on the return conveyor belt 62. These components 48 can then run through the frame 20 again.

The formation of the conveyor belt 38, as in Fig. 6 shown has the advantage that even relatively small components 48 can be placed on the upper run 38 without falling through the passages 44. This is achieved by the wire link belt 45, which has a relatively small mesh size. It is essentially the mesh size that determines the size of the passages 44. The wire link belt 45 is advantageously dispensed with, as a result of which the passages 44 become larger, but there is a risk that smaller components will fall through the passages 44. Fig. 7 shows components 48 on a component carrier 68. Such component carriers 68 are preferably used for conveyor belts 28 without a wire link belt 45. The component carrier 68 has a base made of lattice bars 70. The components 48 rest on this base and cannot fall through between bars 43. There is also the possibility of attaching the components to the component carrier 68, for example by means of clamping devices (not shown) or by means of a cover (not shown) which is made from bars in the same way as the bottom and presses against the components 48 from above. The distances between the bars 70 are based on the size of the components 48. In Fig. 7 if the distances are chosen to be relatively small, they could be chosen to be at least three times as large. It is possible to provide different component carriers 68 in which the arrangement of the bars 70 is geared towards specific components 48.

The Figures 1 and 2 each show two gantry cranes 64, one of which is assigned to the input station 22 and one to the output station 23. An electromagnet 66 is arranged in each case on the portal beam. Ferromagnetic components 48 can be connected to the electromagnet 66 and transported in this way. This facilitates the manual work of an operator, as is shown in the area of the input station 22 and in the area of the output station 23.

The high-pressure cleaning device for soiled components 48 has a) a frame 20, b) a conveyor belt 28, which is guided around pulleys, which forms an upper run 38, on which the components 48 are in operation, and a lower run 40, and a large one Number of passages 44, c) an input station 22, which is located in the vicinity of a front deflection roller 30 and has an input table 46, d) an output station 23 which is located in the vicinity of a rear deflection roller 32 and has an output table 50, e) an upper nozzle arrangement 56, which is arranged above the upper run 38, which is rotatable about a vertical axis of rotation and has downwardly directed nozzles onto the upper run 38, and f) a lower nozzle arrangement 54, which is arranged between the upper run 38 and the lower run 40 is rotatable about a vertical axis of rotation and has nozzles directed upwards towards the passages 44.

Terms such as essentially, preferably and the like, as well as information that is possibly to be understood as imprecise, are to be understood in such a way that a deviation of plus minus 5%, preferably plus minus 2% and in particular plus minus one percent from the normal value is possible.

In the different figures, parts that are equivalent in terms of their function are always provided with the same reference symbols, so that they are usually only described once.
