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.
  • 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 to create, which is arranged mobile on a suitable vehicle and a largely low-loss water circuit for rinsing and suction of 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.
  • a device in which both the cleaning nozzle of the flushing device and the suction head of the suction unit are fed by a common high-pressure water pump, the high-pressure water jet generated by the high-pressure water pump being passed through a three-way valve into a liquid jet fed to the flushing head and into one as driving water for the liquid jet acting as a jet suction device or ejector can be divided.
  • the device preferably 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, which are used to rinse the sewer with service water, to suck off the waste water and to process the waste water into service water, and the trailer attachment is provided for receiving the sludge container.
  • the functional connection between the vehicle attachment on the one hand and the trailer attachment on the other hand can be established by hoses that can be quickly coupled.
  • filtered water with a relatively high degree of purity must be made available in order to ensure the least possible wear on the high-pressure water pump.
  • the permissible size of the dirt particles is approx. 100 ⁇ m.
  • 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 container 1, from which domestic water is sucked at 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 led to the 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 motive water flow introduced into the suction head 7 and accelerated by nozzles generates a vacuum 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 sludge container 9 located on the trailer attachment 15. Since the ejector is located at the bottom of the suction hose, both the suction properties and the pressure properties of the jet suction device can be used. 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 in a multi-stage water treatment device 13 to a very high degree of purity 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, contains 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 are found settle on the perforated plate 10, while dirty water is pumped out of the sump 11 from the left part of the sludge tank 9 by the dirty water pump 12.
  • 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 solid particles are separated from the process water by vortex formation, 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.
  • differential pressure sensor 135 If the degree of filter contamination and, accordingly, the differential pressure measured by differential pressure sensor 135 exceeds a preset value, the filter is backwashed and the surface of the filter fabric is freed of dirt particles.
  • cleaned water is sucked out of the water tank 1 by a centrifugal pump 136 and fed at 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 removed 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.
