Definitions

  • the present invention relates to a machine for obtaining and purifying water contained in waste intended to treat waste generated in farms, towns, industries, farms, etc., such as slurries, lozenges, vinasses or the like, and which pose a serious environmental problem.
  • the machine of the invention has a compact and economical constitution, which allows continuous operation and high process capacity to obtain and purify water from various waste.
  • the machine comprises a pump for suction of the waste from a storage pit or the like, a pump that drives them towards a solid-liquid mechanical separator by pressing.
  • a solid-liquid mechanical separator by pressing.
  • the residues are compressed so that they expel all the water they contain for their subsequent treatment, the remaining solid residue can be used as fertilizer.
  • the liquid obtained (water with contaminants) is conducted to a microfilter based on progressively reduced micron filters, and ideally constituted by rotofilter bases, flint filters and cartridge filters mounted consecutively or in cascade, and can arrive in
  • the machine finally includes a purifier based on reverse osmosis or ultrafilters.
  • a purifier based on reverse osmosis or ultrafilters.
  • reverse osmosis a self-cleaning of the membranes by ultrasound has been included, which allows continuous and long-lasting operation of the machine.
  • all the contaminating material is retained, obtaining practically pure water that can be purified by adding chlorine, or pouring it at any type of flow.
  • the machine has a mainly hydraulic operation, so that with low power electric motors, the movements necessary for its operation are obtained, which will be controlled by a simple control electric unit.
  • Figure 1 shows an exterior view of the machine of the invention.
  • Figure 2 shows a diagram of the machine of the invention.
  • Figure 3 shows a detail of the thrust plate of one of the pressures of the solid-liquid separator of the machine of the invention.
  • the machine 1 of the invention comprises a suction pump 2, with level 3 probe for autonomous connection / disconnection.
  • This pump is submerged in a pit 4 where the slurry or waste to be purified is stored.
  • the aspirated residue is driven to a mechanical solid-liquid separator 5 by pressing, consisting of one or more (ideally two) successive presses 6 of the residue.
  • Each presser 6 comprises a cylinder whose wall or contour 7 is constituted in a filter mesh of suitable pitch size, and whose interior runs a compression plate 9 driven by a piston
  • the microfilter 18 comprises, in this example, two rotofilters 19, of 150 microns of passing light, a flint filter 20 and a filter 21 of cartridges, obtaining at its outlet water with suspension elements smaller than a mire size.
  • the rotofilters are joined by a coil 22 provided with dispensers 23. If the product requires it, by means of these dispensers, usual chemicals can be added in water purification, such as flocculants, coagulants or hydrochloric acid.
  • the rotofilters 19 are provided with scrapers 24 of the remains and flocs towards a hopper 25 that accumulates them at the entrance of an auger 26 capable of compressing them to make them lose the last remains of moisture, and which subsequently evacuates them through an opposite outlet 27.

  • the machine includes the purifier 33 with ultrasonic self-cleaning.
  • This treatment plant is necessary since the solids in suspension have been removed from the liquid but it has a large load of organic matter or other contaminants.
  • This organic treatment plant may consist of a filter of membranes of reverse osmosis or in an ultrafilter. In this exemplary embodiment it is a reverse osmosis membrane filter and a pump 34 that supplies the necessary pressure.
  • Each membrane is inside a pressure cylinder 35, through which outlets one obtains osmotic water 36 and another rejection water 37, the volume of osmotized water being disinfectable by means of a chlorine meter 38 and measurable by a meter flow rate 39, for accumulation in a tank 40.
