Definitions

  • the invention relates to a filling device of non-homogeneous liquids, such as manure, manure, sewage sludge or fecal matter.
  • the filling of the slurry tanker is a bottleneck because it lacks efficient and above all flexible filling devices.
  • a compressor or a pump is mounted on the slurry tank, which promotes the liquid manure from the pit into the drum truck via a suction hose.
  • additional filling devices with a suction wheel are known from practice, which are interposed in the suction line between the compressor / pump and pit.
  • the intermediate filling device takes over the further promotion.
  • Maximum pressure and suction capacities of up to 7000 l / h can be achieved so that even large drum trucks can be filled in just a few minutes. Under certain circumstances, even the use of internal compressors and pumps can be completely dispensed with.
  • a shredder pump is known in which the cutting gap in the area of a chopper plate and cutting parts is adjusted by the drive shaft is moved over a bearing cap by adjusting adjusting screws.
  • the invention is based on the object of improving a filling device for the suction conveyance of non-homogeneous liquids, such as manure, manure, sewage sludge or faeces, in their effectiveness and performance by means of a simple adjustability of the cutting blade.
  • the filling device for suction conveyance of non-homogeneous liquids, such as liquid manure, manure, sewage sludge or fecal matter, has a housing with a suction nozzle and a discharge nozzle and a suction wheel mounted in the housing and supported on a drivable shaft, a cutting knife interacting with a counter cutting blade in the region the intake is provided, wherein the shaft extends with one end up into the intake and the cutting blade is rotatably attached to this end of the shaft and the shaft is mounted to adjust the cutting gap between the shear and cutting blade axially displaceable in the housing.
  • the adjustability of the cutting blade is made possible by a coaxially arranged around the shaft adjusting sleeve, wherein a rotation of the adjusting sleeve causes a displacement of the shaft in its axial direction.
  • the grain size of the solids in the non-homogeneous liquid can be adjusted, thereby avoiding damage to the compressor's own pumps and, for example, a screw eccentric pump.
  • the shaft may be mounted on the adjusting sleeve, wherein in particular two spaced bearings may be provided for supporting the shaft.
  • the adjusting sleeve is preferably mounted on an outer side of the housing, wherein this can be done for example via a threaded connection. A rotation of the adjusting sleeve causes a displacement of the adjusting sleeve together with the shaft relative to the housing.
  • the suction wheel is surrounded by a concentrically arranged around the shaft, cylindrical housing part and the discharge nozzle is preferably connected tangentially to this cylindrical housing part.
  • an additional suction rotor rotates with the shaft in order to accelerate the non-homogeneous liquid, wherein the suction rotor is arranged in particular in the region of the intake.
  • a scraper is provided in the region of the discharge nozzle, the scraper edge is aligned parallel to the shaft and the scraper for adjusting a gap between the scraper and suction wheel is arranged adjustable.
  • the gap can be kept as small as possible, thereby maximizing the capacity of the filling device.
  • a coupling region is provided on the end of the shaft opposite the cutting blade, which is designed, for example, as a splined shaft region.
  • a drive for example, a cardan shaft drive or a hydraulic motor into consideration.
  • the in the FIGS. 1 to 4 Filling device shown serves for suction promotion of non-homogeneous liquids, such as liquid manure, manure, sewage sludge or feces. It is mounted on a trolley between a suction line and a drum and serves to suck non-homogeneous fluids through the suction line and to promote into the drum.
  • non-homogeneous liquids such as liquid manure, manure, sewage sludge or feces.
  • the filling device consists essentially of a housing 1 with a suction nozzle 2 and a discharge nozzle 3 and a mounted in the housing and held on a drivable shaft 4 suction wheel 5.
  • the suction wheel 5 is surrounded by a concentrically arranged around the shaft, cylindrical housing part 1a and the discharge nozzle 3 is connected tangentially to this cylindrical housing part 1a.
  • the intake manifold 2 is arranged coaxially around the shaft 4 and has an intake opening.
  • the suction line not shown, is flanged to the intake manifold 2, while a non-illustrated, leading to the trolley line is coupled to the discharge nozzle 4.
  • the shaft is held by an adjusting sleeve 6, wherein the adjusting sleeve 6 is rotatably mounted on the outside of the housing 1 via a threaded connection 7.
  • the shaft 4 is supported in the adjusting sleeve 6 via two spaced bearings 8, 9, wherein a rotation of the adjusting sleeve 6 causes a displacement of the adjusting sleeve together with the shaft 4 relative to the housing 1.
  • the shaft 4 protrudes through the housing 1 into the intake 2.
  • a cutting blade 10 is rotatably mounted, which cooperates with a counter-blade 11.
  • a rotation of the adjusting sleeve 6 thus causes an axial displacement of the shaft 4 together with the cutting blade 10 relative to the counter-blade 11.
  • resulting cutting gap 12 are infinitely adjustable. While in Fig. 3 no cutting gap is set is off Fig. 5 one corresponding cutting gap 12 can be seen.
  • the associated axial positions of the adjusting sleeve 6 with respect to the housing 1 are from the 4 and 6 seen.
  • the size of the cutting gap 12 determines the grain size, are comminuted to any solid components of the pumped liquid.
  • the grain size is to be adjusted so that a pump provided on the drum, in particular an eccentric screw, is not damaged.
  • the size of the cutting gap 12 depends in particular on the type of solids and the pump to be protected.
  • a suction rotor 13 co-rotating with the shaft 4 is provided in the region of the intake nozzle 2, which is held on the shaft 4 via a bushing 14 and is intended to cause a pre-acceleration of the non-homogeneous liquid to be conveyed.
  • Both the suction 5 and the suction rotor 13 are, for example via feather keys, rotatably supported on the shaft 4.
  • suction wheel and suction rotor enough clearance to the walls of the housing in order to ensure the axial displacement of the shaft 4 (together with suction and suction rotor) by turning the adjusting sleeve 6.
  • the protruding from the adjusting sleeve 6 end of the shaft 4 is provided with a coupling portion 4 a, to couple a suitable drive, not shown, for example, a cardan shaft drive or a hydraulic motor.
  • the suction wheel 5 is dimensioned so that as possible small gap between the peripheral surface of the cylindrical housing part 1a and the blades of the suction wheel 5 is made.
  • a scraper 15 is also provided with a scraper edge 15a, which is adjustable in the direction of the double arrow 16 in order to set a minimum gap between the scraper edge 15a and the suction 5.
  • the adjustment is expediently carried out mechanically in that the wiping edge 15a is held, for example, by means of a screw in a slot on the housing.
