Definitions

  • the invention relates to an extractor for substances containing a liquid, comprising a cage with volume variation by opposite plates, and the corresponding extraction method.
  • press corresponding to the preamble of claim 1 (German patent DE-A-2945254), it is a pneumatic tank press, rotating around a longitudinal and horizontal axis, comprising a filling orifice and drain and whose closure consists of a filter cover while inside the tank is mounted a compression membrane, similar in shape to that of the tank, arranged coaxially with the axis of rotation of tank. Said membrane therefore dividing the tank into a pressure chamber and into an extraction chamber.
  • This extractor has the advantage of exerting a uniformly distributed pressure on the substance, which results in gentle pressing at low pressure.
  • This design also lends itself to pre-extraction by centrifugation, by rotating the tank several times without using pressure.
  • the extraction operation is carried out after rotation of 180 ° of the tank which brings the filling orifice provided with a filter in the low position 1 however, during the crumbling of the wafer, a decompression of the membrane, followed by a rotation of the tank, are necessary; which causes a mixing of substance which leaves a relatively high rate of sludge and turbidity.
  • the present invention aims to remedy the drawbacks presented by the presses mentioned above, because this invention, as characterized in the claims, solves the problem of creating an extractor, for substances containing a liquid, allowing. to obtain a good distribution of the substances on the bottom of the cage during loading, to carry out pressing by successive pressure stages until the desired level of extraction is obtained, to place the cake perpendicular to the pusher plates, while retaining the central part of this cake during crumbling, in order to use it as a filtration mass to reduce the rate of sludge to a very low level, to eliminate the residues without human intervention, and being suitable for full automation of the process, from loading to elimination of residues, taking into account the state of the substances to be pressed.
  • the figures represent an extractor for substances containing a liquid, essentially comprising a perforated rotating plate 1 resting on rollers 2, centered and driven by wheels 19 and a pinion 31 a roller chain 4 and a motor 5; perforated vertical fixed panels 6, surmounted by a cover 7; of push plates 8 and 9. of a drain pan 12 fitted with a hatch 13 overhanging a screw serving as a discharge device 14.
  • the extractor comprises a cage with variation in volume by opposite pusher plates 8 and 9, which is delimited, in the lower part, by a circular perforated circular plate 1, surmounted by two perforated vertical fixed panels 6, at the top, by one or more hinged panels forming a cover 7, and, at the end. by two vertical push plates 8 and 9 moved by jacks 10 and 11 or other such means, guided laterally by slides 17 or raceways.
  • the horizontal circular openwork rotary plate 1 is provided. in its center 1 of one or more perforated hatches 15, articulated downwards. This circular perforated circular plate 1 rests on a raceway, its centering and its rotation drive are provided by wheels 19, one of which is motorized.
  • the liquid recovery tank 12 is provided, plumb with the hatch or hatches 15 fitted to the circular perforated circular plate 1, with a hatch 13 overhanging a device for discharging residues, and possibly the liquids obtained, which are collected at a selector 16 which distributes them.
  • the openwork vertical panels 6 consist of hardwood or plastic blades, arranged horizontally, connected by uprights.
  • each pusher plate 8 or 9 is coated with a wooden plate or a stainless steel plate.
  • the hatch 13 for eliminating residues, fitted to the recovery tank 12, is articulated upwards so as to come, in the maximum open position, to rest against the edge of the opening of the hatch 15 arranged in the circular plate openwork turning 1.
  • the tightness, at the hinge of articulation of the hatch 13 for elimination of residues, is obtained by a baffle mounting.
  • the hatch 15, arranged in the circular rotating plate 1. comes to bear against the edge of the opening of the hatch 13 for eliminating waste in order to constitute, with said hatch 13, an evacuation hopper.
  • the substances to be pressed are distributed uniformly by rotation of the horizontal circular perforated rotating plate 1, and that, after the cage is closed, the two pusher plates 8 and 9 are brought together, by successive pressure stages, until the desired level of extraction is obtained.
  • the substance to be pressed is, during the rapid removal of the pushing plates 8 and 9, transformed into a cake 18, located in the middle of the horizontal circular perforated rotating plate 1 above the evacuation hatch 15. It is then sufficient to rotate the perforated horizontal circular plate rotating 1 by 90 ° to bring the cake 18 perpendicular to the pusher plates 8 and 9, which, during the next compression, advance simultaneously at high speed, with control of this advance by a pressure sensor, for the passage at slow pressing speed.
  • the cake 18 is crumbled, according to cleavage planes, around a central core constituting a filtering mass.
  • the extracted liquid flowed into the recovery tank, passing through the orifices provided in the circular rotating plate and through the gaps existing between the blades constituting the side panels of the cage.
