Definitions

  • the invention relates to a device for the treatment of biomass according to the preamble of patent claim 1.
  • the invention is therefore based on the object biomass, as it is produced as a byproduct in industrial production processes, further to better exploit the biomass underlying value creation potential.
  • a basic idea of the invention consists in separating the liquid phase present in the biomass as far as possible by mechanical compaction of the biomass. This reduces the intrinsic moisture content of the biomass, which at the same time causes an increase in the calorific value. This proves to be a great advantage, especially with a subsequent thermal utilization of the treated solid phase.
  • the emerging in the course of compaction from the biomass liquid phase is collected for further processing, the numerous substances contained therein depending on their material Composition can be used for the respective purpose.
  • the liquid phase of the biomass is thus made usable for the first time as valuable material.
  • a device according to the invention Compared with devices which only thermally process the biomass, it is thus possible for a device according to the invention to tap the potential inherent in the biomass much better. At the same time, a device according to the invention is distinguished by a faster and more cost-effective preparation, which constitutes a decisive economic advantage over known devices.
  • the first pivot bearing of the pressure plate for compressing the biomass is displaceable and formed the second pivot bearing stationary.
  • preferred is an embodiment with two sliding pivot bearings. This makes it possible to move the pressure plate also translationally in the pressure chamber, so that over the entire pressure surface of the pressure plate, a uniform pressure on the biomass can be exercised.
  • the feed of the pressure plate is achieved with hydraulically driven cylinder piston units with which high feed forces can be generated at finely differentiated control.
  • a hydraulic cylinder-piston unit is also used for the advance of the lower pivot bearing, the first and second cylinder-piston unit can share components of the hydraulic drive and the control, which increases the economic efficiency of the invention.
  • hydraulic drives and mechanical drives such as spindle drives are within the scope of the invention.
  • the first Cylinder piston unit and second cylinder piston unit independently operable. This opens up the possibility of subjecting the printing plate in the course of the movement for compressing the biomass different movement sequences, ranging from a pure translational movement or a pure pivoting movement to any superposition of translational motion and pivoting movement. This makes it possible to adapt the processing to the respective properties of the biomass. But also for maintenance and repair work, the pressure plate can be brought into a favorable position for the maintenance staff.
  • a preferred embodiment of the invention provides that the biomass is pressed in the course of Gutaufleung of the pressure plate against a perforated die. In this way, short flow paths for the liquid phase contained in the biomass are achieved until they exit, with the further advantage that the liquid phase is very quickly and efficiently separated from the biomass. If the perforated die becomes clogged in the course of the material preparation, it can be replaced by another without much effort and time to resume operation.
  • the first cylinder piston unit is set back relative to the second cylinder piston unit in the direction of the rear wall. This results in the inlet region of the pressure chamber greater flexibility in the motion control of the printing plate, which can be driven in this way relatively far in the direction of the rear wall.
  • the first cylinder piston unit may have a larger piston stroke than the second Cylinder piston unit.
  • the printing plate relative to the direction of movement of the biomass different pressure surface areas, each with a different inclination relative to the end wall of the pressure chamber in order to influence the movement of the biomass during compaction by the pressure plate.
  • the first area of the pressure surface can be inclined more towards the end wall in order to counteract a movement of the biomass in the course of the compression back into the product inlet.
  • the Fig. 1 and 2 show a first embodiment of the invention, in which the biomass flows through the device substantially vertically from top to bottom.
  • the device has a cylindrical pressure chamber 1, which is formed by two plane-parallel to the plane of representation in mutually light distance from each other extending side walls 2, which are interconnected at their lateral ends by an end wall 3 and a rear wall 4.
  • the side walls 2, the end wall 3 and the rear wall 4 are held in a machine base frame 5, which is supported by vertical supports 6 on the ground.
  • a displaceable in the horizontal direction pressure plate 7 is arranged, which extends from the one side wall 2 to the opposite side wall and the pressure chamber 1 facing the pressure surface in the clear distance of the end wall 3 opposite.
  • the pressure surface is inclined relative to the central region in the direction of the pressure chamber 1, in the lower edge region, however, in the direction of the rear wall 4.
  • an upper pivot bearing with a horizontal upper bearing axis 13 is seen in the upper edge region and underneath a lower pivot bearing lying in the lower edge region with a horizontal lower bearing axis fourteenth
  • the inventive device further comprises an upper cylinder piston unit 8 and an axially parallel arranged lower cylinder piston unit 9.
  • the two cylinder piston units 8 and 9 are with their cylinders 10, 10 'each rigidly anchored in the rear wall 4, wherein the upper cylinder 10 relative to the lower cylinder 10th 'is set back and has a relation to the lower piston 10' larger piston stroke.
