    The invention relates to automatic cleaning drainage system with rotating flexible spiral auger. The invention can be applied to two-stroke cross-head type motors. The invention is particularly suitable for use in the drainage systems and pipes which drain the piston rod packing boxes of the engines (also known as Piston rod stuffing box ”) and also purge air belts. (in English: Scavenge air space or piston underside space). The invention is furthermore suitable for use in the drainage systems that drain from the engine's flushing air tank (scavenge air receiver)
    The invention can be used both as retrofitting to existing motors and systems, as well as for mounting on new motors and systems.
    The invention can be applied to both pressurized and non-pressurized (open) sinks and piping systems.
    FIG. 1 and FIG. 2 shows an embodiment of the drive unit (prototype) The embodiment shown is intended for pressurized drainage systems (drainage from the engine rinsing belts and containers) Note that Figs. 1 shows a blunt auger mounted in a raised demonstration tube (fig1-b). The embodiment shown is made with traditional shaft seal (fig1-c / fig2-a). Its function is to seal against the pressure present in the tube (rinsing air pressure). The shaft (Fig. 2-b) transmits the slow rotating motion from gear motor to spiral auger. The housing (fig2-c) serves both as the foundation of the export and as the end of the pipe flange. The bearing housing (Figs. 2-d) absorbs the axial and radial forces of the shaft via a ball bearing. The gear motor (Fig. 2-e) produces the rotation of the shaft / auger. The rotary power of the gear motor is transmitted through a spring split, mounted through the holes (fig2-f + g) The purpose of the spring split is to secure the auger and gear motor against destructive overload. The function of the sliding bearing (fig2-h) is partly to absorb the radial forces of the shaft (fig2-b) and partly to compress the traditional shaft seal (fig2-a). The compressive effect is obtained by tightening the bolts (fig2-i) so that the sliding bearing (fig2 -h) is pulled towards the housing (Fig2-c) thereby obtaining a sealing effect between the rotating shaft (Fig2-b) and the stationary housing (Fig2-c). using a pin screw (Fig2-J) in a recess in the shaft. The protective shield (fig2-L) is mounted on the housing (fig2-c) so that it protects against access to the rotating shaft (fig2-b) The inductive sensor (fig2-m) monitors the desired rotation of the shaft.

    -2Fig. 3 and FIG. 4 shows an embodiment of the drive unit (prototype) The embodiment shown is intended for pressure-free (open) drainage systems (drainage from the engine's piston rod packing boxes). The embodiment shown is made with container / tray for precipitation and solid collection. The gear motor (Fig3-a) is mounted with bolts on the drive unit box (Fig3-b).
    c) is mounted directly on the shaft of the gear motor. The gear motor transmits its rotary motion through the spring split (Fig4-a). The inductive sensor (fig4-b) monitors the rotation of the auger. The spiral screw enters solid / sluggish liquid through the tube (fig4-c) A mixture of light liquid oil and solid / sluggish liquid drops from the tube (fig4-c) into the precipitation vessel (fig4-d) The precipitating vessel will eventually overflow whereby mainly oil will leave the drive unit through discharge pipes (fig3-d) The solid / sluggish liquid will precipitate / settle in the precipitator (fig4-d) When the precipitator is full, it can be emptied manually by lifting it out of the drive box (fig3-b) ) The lid (fig3e) is kept closed by hand screws (fig3-f) during normal operation. The gas pistons (Fig. 4-e) hold the lid in the open position while working in the drive box. The safety switch (fig3-g) prevents starting of the gear motor (fig3-a) when opening the lid (fig3-e)
    It is known from two-stroke engines of the crosshead type that drain pipes completely or partially clog during operation (Fig6). This phenomenon arises due to the composition of the medium. The medium consists of lubricating oil mixed with solid particles in the form of uncombusted particles (sludge). These solid or sluggish liquid components tend to precipitate / settle and accumulate on the inside (bottom) of the pipe. This builds up relatively quickly, layer by layer, completely or partially clogging the pipe during engine operation. The built-up material in the pipe has almost the same consistency as hard stamped soil. The phenomenon occurs because the flowing part of the medium (the oil) flows through the tube, without being able to keep the solid / sluggish liquid components in sufficient motion. There are known examples where such pipe systems are clogged after only 3 weeks of operation since the last cleaning. Today, the problem is solved mainly by manually separating pipe systems and manually cleaning them by means of iron bar cleaning tapes and other known pipe cleaning tools. However, this results in relatively high consumption of working hours.
    DK 2017 00364 A1
    -3There are known examples of consumption of over 1000 working hours on manual cleaning of these pipes annually. In addition, the work is the scene for those involved, as it often takes place in inconvenient positions and often involves the use of toxic and potentially harmful chemicals and or diesel oil.
    The purity of the pipes is important for the operation of the engine. Full or partial clogging of said pipe may cause significant operational and safety problems in connection with engine operation.
    The object of the invention is to prevent accumulation / complete or partial clogging of drainage pipes during continued operation of the engine, by means of adapted rotation of flexible spiral auger. The invention will lead to trouble free operation of these two stroke engines and will drastically save man hours for manual cleaning. In addition, the invention could significantly save on the consumption of cleaning chemicals and diesel oil consumed in connection with manual pipe cleaning.
    The rotating flexible spiral auger is known from flex augers which e.g. used for transporting feed and granules in e.g. agriculture. In these applications, the auger is characterized by a relatively rapid rotation and the primary function of the auger is the transport (auger run) of dry feed or granules through a tube.
    The rotating flexible spiral auger is further characterized by being flexible so that it can follow and function in any soft bends of the tube.
    In the automatic cleaning drainage system with rotating flexible spiral auger, the primary function of the auger is to prevent the deposition of solids (sludge). This is achieved by a relatively slow rotation which produces a scraping effect on the inside of the tube. The primary medium transport through the tube is effected by flowing through the hollow diameter of the coil, as well as along the gap between the outer diameter of the coil and the inner diameter of the tube. (Fig. 5)
    DK 2017 00364 A1
    -4Current flow occurs by gravity due to the slope of the tube or due to pressure difference between the inlet and outlet of the tube. There are also systems where flow occurs as a result of a combination of gravity and pressure difference.
    Various rotary pipes and drain cleaners are known. These are characterized by pushing a wire-like cleaning belt through an opening in the pipe. These are usually handheld and require access to an opening in the tube. These pipe / drain cleaners are typically used when a pipe is completely or partially clogged. The purpose of these is to punch in a possible. clogging (plug) in the pipe. These devices are not intended for phase mounting and continuous preventive operation.
    The automatic cleaning drainage system with rotating flexible spiral auger is characterized by being fixed in the pipe system. The speed of the spiral screw is adjusted so that a relatively clean tube is maintained by preventing the deposition and build-up of solid and / or sluggish liquid material. The speed of the auger is adjusted slowly to avoid unnecessary friction between the auger and pipe wall. This avoids unnecessary wear and temperature rise on the rotary auger. The rotary motion of the coil can be both constant speed, as well as varying speed. The invention can also be carried out with intermittent (start / stop) rotary motion.
    The invention is further characterized by having a drive unit mounted at one end of the pipe. The scraping / cleaning motion of the spiral screw can take place with direction of movement away from the drive unit - as well as direction of movement towards the drive unit. The drive unit produces a rotary movement of the helical screw. The rotary movement of the drive unit can be carried out using: electric motor / actuator, hydraulic motor / actuator, pneumatic motor / actuator, mechanical rotary actuation or manual (manual)
