Definitions
- the invention relates to a device for cleaning sewers by rinsing by means of water in which rinsing devices and suction devices are used.
- a sludge suction vehicle in which the flushing devices are supplied with flushing water by a high-pressure pump via high-pressure water hoses, which is removed from the water tank.
- a second pump unit is used to extract the dirty water.
- suction water jet pump There is one on the cleaning vehicle for conveying the sludge attached, suction water jet pump provided, the motive water flow is generated by a low pressure water pump.
- a sewer cleaning vehicle which has a water tank, a flushing device and a high-pressure pump for conveying flushing water from the water tank to the flushing device and also a suction unit, a suction line and a suction basket for sucking in dirty water.
- the dirty water is passed through a filter device and converted into process water that is fed to the tank.
- a device for suctioning water and sludge from a retention basin is known.
- the device is mounted on a motor vehicle. It has a tank with a flap, which is divided into several sedimentation tanks by several plates. The last pool near the flap is used to hold the sludge, while the first pool is said to contain the reasonably purified water.
- a pump with its own drive motor is arranged next to the tank, which sucks the water out of the tank and conveys it to a suction / pressure unit via a three-way valve.
- the suction / pressure unit is introduced into the retention basin during operation and i conveys the sludge-water mixture from this via a pressure line into the tank.
- a hose that runs over a hose drum is used as the pressure line.
- the three-way valve also serves to connect the pressure side of the pump in a second position to a drain line which runs along under the tank when a further suction line is introduced into the retention basin via a further valve arrangement in order to draw off the upper liquid layer therefrom.
- the water pumped from the retention basin in this way is simply drained onto the street through the free end of the drain line.
- the three-way valve therefore differentiates between two operating positions, namely once the water is directed from the tank to the suction / pressure unit to convey a water-sludge mixture and in another position for sucking off the water layer above the mud and discharging it onto the road.
- DE-C-686 519 discloses a tank car for cleaning sink boxes which works by means of a suction hose and which consists of a work vehicle and a trailer wagon separate therefrom.
- the work vehicle contains a feed tank, which has approximately the volume of a sink box to be emptied, while the trailer wagon carries a sludge container.
- the feed tank is firmly mounted on the work vehicle together with a three-way valve and other components, and the sludge tank is also not removable from the trailer truck, but can only be swiveled up on it for the purpose of emptying.
- Separate pump units are used both for the implementation of the flushing process by commissioning the flushing device and for the suction of the dirty water by means of a corresponding suction unit, which leads to expensive and complex solutions.
- the efficiency of the pump unit used to draw in the dirty water depends on the suction height to be overcome.
- the impairment of the suction height can lead to the suction flow being cut off and thus to cavitation and thus damage to the pump set.
- the maximum delivery head in suction systems when using a vacuum pump is physically limited to around 8 m, taking into account the atmospheric pressure and the specific weight of the pumped medium.
- the invention has for its object a cost-effective device for cleaning sewers with high operational reliability and to create a large conveying capacity which is arranged in a mobile manner on a suitable vehicle and has a largely low-loss water circuit for rinsing and suctioning off mud, sand, faeces and the like. is guaranteed and is also suitable to convey the sludge up to a sludge tank over a height of at least 15 m.
- the heavily polluted water in the sludge tank sucked in by the jet suction device should be cleaned in such a way that the high-pressure water pump can be continuously supplied with water of sufficient quality from the water tank.
- the device according to the claim serves to achieve this object.
- a feature of the invention is that the device consists of two modules designed as containers, of which one container is a vehicle attachment and the other container is a trailer attachment, the vehicle attachment for receiving the container for the process water, all units that the Rinse the sewer with process water, suction the dirty water and process the dirty water to process water, and the trailer attachment is provided to hold the sludge tank.
- the functional connection between the vehicle attachment on the one hand and the trailer attachment on the other hand can be established by means of quick-connect hoses.
- the device according to the invention is expediently assigned to two mutually independent containers.
- One of the two containers is designed as a vehicle attachment 14, the other container as a trailer attachment 15.
- suitable lifting means both the vehicle attachment 14 and the trailer attachment 15 can be parked at the place of use and put into operation together.
- the preferred embodiment provides for the vehicle attachment 14 to be equipped with a filled water tank 1, from which domestic water is pumped with a water pressure of approximately 210 bar by a high-pressure pump 2 driven by a diesel unit 3.
- a high-pressure pump 2 driven by a diesel unit 3.
- a three-way valve 4 which divides the liquid flow and continues it in two lines.
- Part of the high-pressure water is fed to a cleaning nozzle 6 via a hose.
- a driven hose reel 5 ensures that the hose and thus the cleaning nozzle 6 are guided in the sewer.
- the suction head 7 which is designed as a jet suction device or ejector, is arranged, with which the sludge suction is carried out.
- the suction head 7 is connected to the second part of the high-pressure water flow supplied by the high-pressure pump 2, which acts as a motive water flow.
- the driving water flow introduced into the suction head 7 and accelerated by nozzles generates a negative pressure in the suction head 7, which sucks in the impurities dissolved by the cleaning nozzle 6 with rinsing water and presses at high pressure through the suction hose 8 into the mud container 9 located on the trailer attachment 15.
- both the suction properties and the pressure properties of the jet suction device can be used, which for this reason is also referred to as a “suction / pressure unit. This means that significantly higher delivery heights can be achieved compared to the purely suction processes .
- the process water is separated from the sludge by a perforated plate 10 and collected in a collecting trough 11.
- the recovered service water is sucked off with a dirty water pump 12 and filtered to a very high degree of purity in a multi-stage water treatment device 13 and returned to the water tank 1.
- the division of the device according to the invention into two containers which can be handled independently of one another, of which one container, in addition to the water container 1 for the used water, all units which serve to rinse the sewer with used water, to extract the dirty water and to process the dirty water into used water, includes and the other container accommodates the sludge container 9 has the advantage that a simple exchange of filled sludge containers 9 with empty sludge containers 9 can be carried out and the device has to accept correspondingly short downtimes.
- the necessary hose connections can be made easily using quick-release couplings.
- FIG. 2 shows details of the water treatment device 13 which is arranged between the sludge tank 9 and the water tank 1.
- the sludge tank 9 is shown reversed from the illustration in FIG. 1, ie the sludge conveyed by the jet suction device via the suction hose 8 enters the sludge tank 9 on the right, in which residues settle on the perforated plate 10, while dirty water from the drip pan 11 is pumped out by the dirty water pump 12 from the left part of the sludge tank 9.
- the dirty water pump 12 conveys the dirty water pre-filtered through the perforated plate 10 via the line 17 into a hydrocyclone 131, in which by vortex formation Solid components are separated from the process water, the specific mass of which is significantly higher than that of water.
- the service water freed from the heavier solid particles flows out of the hydrocyclone 131 at the top and is fed from above into a buffer tank 132, which serves to collect service water bursts and to continuously supply service water to a downstream backwash filter.
- the process water is sucked out of the buffer tank 132 by a sludge pump 133 and fed to a last filter stage, namely the backwash filter 134.
- This filter stage ensures that the dirt particle size in the water tank 1 does not exceed the size of 100 microns.
- the filter effect is achieved by a filter fabric applied to the circumference of a drum. With increasing contamination of the filter surface, the pressure difference between the filter inlet and the filter outlet of the backwash filter 134 increases, which is detected by a sensor 135 and passed on to a controller 16.
- the filter contamination level and accordingly the differential pressure measured by the differential pressure sensor 135 exceed a preset value, the filter is backwashed and the surface of the filter fabric is thus freed of dirt particles.
- cleaned water is sucked out of the water tank 1 by a centrifugal pump 136 and fed with a pressure of about 6 bar to a cleaning arm 139, which is arranged in the backwashing filter 134 and rinses the filter fabric.
- the cleaning arm 139 has a nozzle, with which rinses the rinsing water from the filter fabric in the opposite direction to the normal filter flow. In this way, even stubborn dirt particles are released from the filter fabric and, together with the rinsing water, are flushed back to the sludge tank 9 via the return line 138.
- the cleaning arm 139 is continuously moved in a circular movement along the filter cylinder surface so that the entire tissue surface can be cleaned during one revolution.
- the process water filtering in the backwash filter 134 is not interrupted during the entire flushing phase.
- a level sensor 137 in the water tank 1 ensures that the level in the water tank 1 is measured and the measurement result is transmitted to the controller 16.
- the water treatment is accordingly regulated with the fill level sensor 137.
- the continuous determination of the degree of contamination of the backwash filter 134 makes it possible to carry out the backwash only when this is actually necessary.
- the not inconsiderable amount of water required for backwashing can be adapted to the fluctuating degree of pollution of the water to be cleaned. This represents a decisive advantage in view of the large amount of water required for the jet suction process.
