Definitions
- Suction dredger for picking up and separating suction material, such as soil or sludge, and methods therefor
- the invention relates to a suction excavator for receiving and separating suction material, such as soil from underground lines or sludge, with a pneumatic suction turbine which is connected to a collecting container for the suction material that is sucked up, in which an outwardly projecting suction nozzle for receiving the suction material flows into and into which a large part of the suction material is separated from the suction air flow and with a filter space following the collecting container with a plurality of filters through which the suction air flow is guided for fine filtering, the collecting container and filter space being separated from one another by a partition wall which forms a passage for the suction air flow, according to the preamble of claim 1.
- the invention also relates to a method for picking up and separating suction material according to the preamble of claim 18.
- a suction dredger which consists of a pneumatic suction nozzle, a hollow cylindrical tool forming its suction piece for breaking up the soil, and a collecting container into which the suction nozzle opens and in which most of the soil from the Suction air flow is separated.
- a suction fan is connected to the collecting tank, a filter being arranged after the collecting tank, through which the suction air flow is sucked and in which the remaining soil is filtered out of the suction air flow.
- EP 0613983 B1 has also disclosed a suction dredger for picking up suction material, in particular for excavating soil on underground lines, which has a pneumatic suction nozzle for receiving the suction material and a collecting container for the suction material that is sucked into which the suction nozzle flows and in which a large part of the suction material is separated from the suction air flow.
- a suction fan is connected to the collecting container, a filter device being arranged between the mouth of the suction nozzle in the collecting container and the suction fan, which comprises a fine filter and an upstream coarse filter.
- the coarse filter is formed by a labyrinthine flow channel in which the suction air flow is deflected several times.
- the partitions are arranged vertically and parallel to one another, the deflections of the flow taking place alternately near the top wall or near the bottom of the collecting container.
- JP-58222231 and JP-58222223 have disclosed similar suction dredgers for the targeted picking up of suction material, in particular for excavating soil on underground lines.
- the excavator has a pneumatic baby's trunk for receiving the suction material, a collecting container for the sucked-up suction material, into which the suction nozzle opens and in which the suction material is separated from the suction air flow, as well as a suction fan connected to the collecting container and one between the mouth of the suction nozzle in the collecting container and the suction device arranged filter device, which comprise fine filters.
- the coarse filter consisting of a room, the bottom surface of which act as a coarse filter below the fine filter, so that larger or heavier particles, which could still pass through the collecting container, still separate from the suction air flow and go to the bottom.
- the coarse filter consists of a single, labyrinth-shaped flow channel, in which the suction air flow in the area of the beginning of the flow channel, coming from the collecting container, is deflected by more than 90 degrees from top to bottom, and now at the end of this flow channel through a deeply drawn side wall to be diverted 180 degrees from bottom to top to the fine filters.
- the flow cross section spreads in the direction of flow.
- the known suction excavators have the disadvantage that they are energy-consuming due to the multiple deflection of the suction air flow and require large-sized suction fans. Furthermore, the filters are difficult to clean because they flow from bottom to top, so that the greatest contamination takes place in the bottom area of the filters and the filters have to be cleaned frequently, for which irrigation systems are known. Because of the multiple chambers or flow channels, the known suction dredgers are space-consuming, which is disadvantageous in particular in the case of mobile suction dredgers mounted on vehicles.
- the invention has for its object to provide a method for the targeted absorption of suction material and an excavator set up for this purpose, with which or over a long period of time a good separation of the suctioned suction material is guaranteed without the filters becoming too dirty, whereby a good cleaning of the filters should be guaranteed during the running excavator operation.
- the suction excavator should also be space-saving and require less energy for the suction process than comparable suction excavators.
- the suction air flow from the mouth of the suction nozzle into the collecting container is either essentially directed towards the upper region of the wall of the collecting container opposite the partition and the passage of the partition is in the upper region thereof, so that inside the collecting container, the suction air flow forms cyclone-like about a horizontal axis from above the wall along the same downwards to the floor and along it towards the partition wall and ascending on the same for passage and outflow via the passage into the filter chamber or the mouth of the suction nozzle laterally in the collecting container takes place and is essentially directed towards the lateral area of the wall of the collecting container opposite the partition and the passage of the partition is arranged offset by 180 degrees with respect to the mouth of the suction nozzle, so that s I cyclically move the suction air flow around a vertical axis within the collecting container.
- the suction air flow from the mouth of the suction nozzle into the collecting container is essentially directed towards the upper region of the wall of the collecting container opposite the partition and the passage of the partition is in the upper region of the same and the inlet of the suction nozzle takes place laterally into the collecting container and Passage of the partition is offset from the mouth of the suction nozzle by 180 degrees, so that the suction air flow in the collecting container cyclone both around a horizontal axis from above the wall along the same downward to the floor and along the same in the direction of the partition and ascending on the same to Passage and outflow through the passage into the filter chamber and from the mouth of the suction nozzle to Passage of the partition wall moved about a vertical axis, so that the resulting suction air flow rotates about an oblique axis.
- the suction air flow flows against the filters essentially horizontally and flows through them essentially horizontally.
- the entry of the suction air flow enriched with suction material into the collecting container and the exit of the cleaned suction air flow from the filters are offset from one another by 180 degrees to 270 degrees and the two suction air flows, the incoming and the outgoing, are separated from one another.
- the suction dredger according to the invention has the advantage that it ensures good separation of the suctioned suction material over a long period of time without the filters becoming too dirty and without the suction power being significantly reduced.
- the suction air flow can either rotate cyclone-like about a horizontal axis or about a vertical axis or about both a horizontal and a vertical axis, so that the resulting axis runs obliquely or the air vortices run obliquely.
- the suction air flow flows against the wall of the collecting container opposite the partition or it is directed directly from top to bottom onto the bottom of the collecting container, so that the suction air flow forms cyclone-like around a horizontal axis within the collecting container with vortices from top to bottom over the bottom away and then upwards in the form of a circular movement of at least 270 degrees.
- the particles then still in the suction air flow, which are still entrained by the suction air flow because, due to their relatively small mass, they can follow the cyclone-like deflection of the suction air flow from bottom to top, flow over the upper edge of the passage of the partition wall and arrive essentially with a horizontal trajectory in the filter room in which a plurality of filters for fine filtering the suction air flow are located.
- the flow is essentially horizontal.
- the suction dredger is also space-saving and uses less energy for the suction process than comparable suction dredgers of the prior art.
- the suction nozzle flows laterally into the top of the collecting container, the passage of the dividing wall being offset by 180 degrees with respect to the opening of the suction nozzle, so that the suction air flow also moves cyclically around the vertical axis within the collecting container with vortices and from it a more or less inclined axis of the air vortex results.
- the passage in the partition is preferably in the upper quarter of the same.
- the filter chamber consists of a filter space, in which the filters are arranged, and an antechamber in front of the filters, into which the passage of the partition opens, the filters being arranged laterally within the filter space after the passage.
- the passage of the partition between the collecting container and the filter chamber is preferably in the upper corner or in the upper region of the partition towards the anteroom and to the side of the filter chamber, so that the suction air flow passing through the passage is deflected to the filters by approximately 90 degrees.
- the filter chamber and vestibule can also coincide.
- the ends of the filters emitting the suction air open into a separate channel which is led through the upper area of the collecting container to the suction turbine.
- This enables a simple structural design and guidance of the two suction air flows.
- the incoming suction air flow contaminated with soil and the outgoing filtered suction air flow are strictly separated from one another in a simple structural design.
- Baffles are advantageously arranged in front of and / or laterally in front of the filters along and at a distance from the filters to protect the filters against flying suction material.
- the baffle plates can consist of an elastic material, such as plastic, and can only be suspended from below.
- An air nozzle is arranged above each filter, which are attached to air supply pipes which are filled with compressed air from a compressed air tank connected to the air supply pipes via a valve.
- the filters are arranged within the filter space at equidistant intervals in rows with equal intervals, the baffle plates of the first, flowed-in row of filters in front of the filters, the baffle plates of the rows of filters underneath each being arranged to the side of the filter and consisting of two parts that the suction air flows between the baffle plates or filters are able to flow through.
- the suction dredger can advantageously be mounted on a transport vehicle, just as the suction dredger can be designed as a transportable and separate container, which is also designed to be tiltable about an axis.
- the suction air flow is directed to the upper region of the wall of the collecting container opposite the partition and opens into one of the upper corners of the partition into the collecting container, the passage of the partition being in the upper region in the opposite upper corner of the partition is so that within the collection container the suction air flow is cyclonic both about a horizontal axis from above the wall along the same downward to the floor and along the same in the direction of the partition and ascending on the same as well as rotating about a vertical axis for passage and outflow forms the passage into the filter chamber, so that the resulting suction air flow is rotated about an oblique axis.

- the collecting container 1 has a wall 25 pointing towards the suction turbine 5, a partition wall 8 opposite this wall 25, behind which there is a filter chamber 2 as well as a bottom 26 and one Upper top wall 4. Above the top wall 4 there is an air guide space 3 for the discharge of the cleaned suction air to the suction turbine 5.
- the filter chamber 2 consists of an actual filter space 27, in which filters 10, 10 'are arranged, preferably suspended vertically, and an anteroom 14 in front of the filters 10, 10 ', so that the filters 10, 10' are arranged asymmetrically with respect to the filter chamber 2 within the filter chamber 2 and laterally after the passage 9.
- the upper ends 28 of the filters 10, 10 ′ which are preferably elongate filter cartridges, penetrate the top wall 4 and open into the air guide space 3 above the top wall 4.
- the side or end wall 6 of the filter chamber 2 is penetrated by the suction nozzle 7 laterally at the top in a corner.
- the suction nozzle 7 can also be guided through the air guide space 3, in which case it then pierces the top wall 4 downwards, for example at an angle, to the collecting container 1.
- the partition 8 has in an upper corner area, which is preferably as far as possible the passage of the suction nozzle 7 through the partition 8, a passage 9 for the passage of the suction air from the collecting container 1 into the filter chamber 2.
- the suction air flow 11, 11 ', 11 "from the mouth of the suction nozzle 7 into the collecting container 1 is directed at the upper region of the wall 25 of the collecting container opposite the partition 8 or at least obliquely downwards from the top wall 4 in the direction of the wall 5 forms the suction air flow 11, 11 ', 11 "in the collecting container 1 cyclone-like about a horizontal axis from above the wall 25 along the same downward to the bottom 26 and along the same in the direction of the partition 8 and ascending there to the passage 9 of the partition 8 and outflow through the passage into the filter chamber 2.

- suction air flow 11, 11 ', 11 "generated by the suction turbine 5 Due to the suction air flow 11, 11 ', 11 "generated by the suction turbine 5, a large part 12 of the suction material separates from the suction air flow 11, 11', 11" in the collecting container 1 due to gravity.
- the suction air flow is directed into the antechamber 14 and flows against the filters 10, 10 'essentially horizontally.
- the entry of the suction air flow 11, 11 ', 11 "enriched with suction material into the collecting container 1 and the exit of the cleaned suction air flow 13 from the filters 10, 10 ' are directed offset from one another by 180 degrees to 270 degrees, preferably by 270 degrees, the two suction air flows being separated from one another.
- a highly effective, asymmetrical air guide filter system is achieved, which is a prerequisite for the cyclone effect within the collecting container 1.
- baffle plates 20, 21 are located in front of and / or laterally in front of the filters 10, 10 'and run at a distance from the filters to protect the filters against flying suction material.
- These baffle plates are, for example, baffle plates which are suspended in a spring-elastic manner, for example by means of springs 22 or by means of oscillating spring elements.
- the baffle plates 20, 21 prevent a direct impact of suction material on the filter.
- the baffle plates can also be elastic in themselves and, for example, consist of a flexible plastic material.
- the baffle plates of the foremost row in the suction direction are preferably made in one piece, those of the rows behind them preferably in two pieces and arranged to the left and right of each filter.
- the baffle plates cause a further failure of suction material 12 'into the filter chamber 2, because the larger particles still present in the suction material of the suction air flow suffer a loss of energy when bouncing against the baffle plates and thereby separate from the suction air flow and fall to the ground.
- the filters behind the baffle plates are supplied with suction air which is loaded to a relatively low degree, which is introduced into the individual filter rows in a targeted manner and is fed to the filters.
- a pneumatic cleaning system of the filters 10, 10 ' is shown in FIG. 6.
- An air nozzle 19 is arranged above each filter 10, 10 ′, which are jointly attached to air supply pipes 18 which are supplied with compressed air from a pressure valve connected to the air supply pipes via a valve.
- Air tank 17 are filled for cleaning the filter.
- the countercurrent principle is used here, which is advantageously cleaned from top to bottom, since experience has shown that the filters in the horizontal flow used here, preferably still in the upper area of the filter, become dirty more quickly at the top than at the bottom, so that the top also lying cleaning system attacks in places of greatest pollution above.
- the filters 10, 10 ' are preferably flowed uniformly and essentially horizontally.
- the filters are arranged within the filter space 27 at equidistant intervals in rows with equal intervals.
- the baffle plates 20 of the first, flowed-in row of filters are arranged in front of the filters and somewhat to the side of them, the baffle plates 21 of the rows of filters behind them are each arranged to the side of the filters and, according to FIG. 7, consist of two parts, so that the suction air flows 23, 23 'between them are able to flow through the filters. This creates a turbulence on the baffle plates with targeted air reversal, which causes the finest suspended particles to be separated further from the suction air, which in turn leads to only slightly contaminated air on the filter surface.
- the passage 9 of the partition 8 is located between the collecting container 1 and the filter chamber 2 in the upper corner or in the upper region of the partition 8 towards the antechamber 14 and laterally of the filter chamber 27, so that the suction air flow passing through the passage to the filters 10, 10 'is turned around 90 degrees.
- the suction dredger is mounted on a transport vehicle 16, the suction dredger being designed as a transportable and separate container, which is held so as to be tiltable about a lateral axis in order to empty the collecting container 1 and the filter chamber 2.
- the filter By positioning the filter, it is possible to completely empty the transport container.
- Suction material 12 which is deposited, stuck together or contains mud is completely emptied when the container is tilted.
- the invention is commercially applicable in particular for suction excavators for picking up and separating suction material.
- the invention advantageously ensures the cleaning of the suction air according to the legal regulations, as in Germany Technical Instructions Air. List of reference numerals:
