  • Patent number: 10640966
    Abstract: A sewer cleaning device has a rinsing hose, to which pressurized water is applied, which is stored on an assigned storage reel and which passes through a transportation apparatus adjacent to the storage reel. A manner of operating, which protects the rinsing hose, is achieved by providing a reel arrangement, around which the rinsing hose is wrapped at least once, having two redirection reels arranged laterally adjacent to one another in the radial direction, which are offset in relation to one another in the axial direction by at least the thickness of the rinsing hose and of which at least one redirection reel is arranged tilted about an axis of symmetry, which perpendicularly intersects the axes of the two redirection reels, so that during each complete wrap around the reel arrangement forming the transportation apparatus by the rinsing hose, a pitch of the path assigned to the rinsing hose results.

  • Patent number: 10526778
    Abstract: In a sewer cleaning vehicle is provided having a container for the water required for cleaning the sewer and/or the sludge obtained during cleaning of the sewer, and an extension arm which is liftable and lowerable and/or rotatable about a vertical axis and which is accommodated on the container for the manipulation of a flushing hose which can be supplied with compressed water and which can be inserted into the sewer. A suction hose with a suction draft can be lowered into the sewer. At least one further working device which is provided for working the sewer and which can be manipulated by the extension arm is carried along on the vehicle and can be loosely accommodated on an associated retaining device provided on the vehicle side and can releasably be coupled to the extension arm when required by an associated coupling device.

  • Patent number: 10150619
    Abstract: A sewer and/or road cleaning vehicle is provided. The cleaning vehicle includes a dirt removal container with a central longitudinal barrel axis, container walls and a container bottom. The dirt removal container has a shape of a barrel and is arranged to accommodate and transport mineral dirt residues collected during cleaning. A clearing device is provided to empty out the dirt removal container. The clearing device includes a conveying screw and is arranged on a carrier inside the dirt removal container. The carrier is pivoted around the central longitudinal barrel axis by a pivoting drive so that the conveying screw is laterally deflected in a first and in a second direction along the container walls relative to a center position associated with the container bottom. A discharge screw assembly is arranged downstream of, and transversely to, the conveying screw to discharge the mineral dirt residues outwardly.

  • Patent number: 10118768
    Abstract: A sewer cleaning device and/or street cleaning device includes a dirt removal container for receiving and transporting mineral dirt residues accumulating during sewer and/or street cleaning. A removal device for clearing out the dirt removal container includes a conveying worm arrangement received on a swivel frame which is swivel-mounted on an axis extending in a longitudinal direction of the container and swivellable by a swivel drive. The conveying worm arrangement is sideways deflectable by the swivel frame relative to a center position associated with the container bottom on both sides along the container wall and a fast discharge of the dirt removal container can be achieved by two conveying worms arranged in symmetrical position relative to a central longitudinal axis of the swivel frame, the conveying worms limiting a gap therebetween and acting together for the transport of the bulk material along the inner side of the container wall.

  • Patent number: 10105738
    Abstract: A device for cleaning and/or inspection of a flow channel is provided including a purge hose introduced into the flow channel, charged with high pressure purge water, and connected to a channel nozzle provided with jet nozzles creating a recoil effect. The channel nozzle is controllable by rotation around its axis. A simple, cost-effective, trouble-free construction and high precision can be accomplished by subdividing the purge hose into at least two sections which are connected with each other by a coupling unit through which high pressure purge water flows. The device has a housing element connected to a purge hose section and a hollow piston element arranged in the housing element in an axially movable manner and connected to another purge hose section. The housing element and the hollow piston element are supported by a spring and are cooperating via a converter converting an axial movement into a rotation.

  • Patent number: 4446591
    Abstract: A vehicle for cleaning drains or cesspools has a tank for taking up and transporting waste material such as sludge, an aspiration pipe and a reel for the pipe. The reel is so placed that, at least when aspiration is taking place, its axis is upright, this making possible the use of a single-piece aspiration pipe which only has to be uncoiled from the reel to the degree necessary to get the inlet end of the pipe to the point at which it is needed within the cesspool or the like.

  • Patent number: 4443908
    Abstract: A sewer cleaning vehicle has a swilling or clean water tank for supplying a sewer cleaning hose having a sewer cleaning nozzle and designed to be lowered into a sewer to be cleaned, a waste tank and a pumping connection joining the waste tank with the swilling water tank. Furthermore, there is a water cleaning unit as part of a system for topping up the swilling water tank with water from the waste tank. For producing a high level of setling effect in the swilling water tank, this tank has generally upright separating walls for causing a division into a number of spaces placed hydraulically in series, the most upstream space being that joined up with the pumping connection.

  • Patent number: 4377475
    Abstract: In the case of an apparatus for sucking up and holding sludge, use is made of a sludge tank which may be evacuated. The sludge tank has a sludge door and a water outlet able to be put into operation separately from the door. The water outlet is made up of an overflow line joined up with water in the sludge tank by way of a filter unit, the filter unit having a cleaning unit with at least one nozzle for jetting water onto the filter unit.
