Definitions

  • My invention relates to a mixing and saturating apparatus which, in consequence of its'novel construction and of its novel way of working, requires much less space, e. g, only one-sixth of the space required hitherto for an apparatus of the same efliciency and which further possesses the advantage that the solid substances are dissolved or suspended as completely as possible in the liquid.
  • the jet of liquid which is under a pres- *sure slightly above atmospheric, enters at a into a jet nozzle b.'Wl10S6 suctlon space is surrounded by a perforated wall 0.
  • a jet 0 is placed above the nozzle 6; it terminates in the mixing nozzle 12 which is mounted coaxially ina vertical circulating tube is and extends with its upper end 7 into the proximity of a distribution sieve.
  • the part of the nozzle p which surrounds the jet pump 0 has perforations e. Borings (Z serve for establishing a communication between the tube 7c and the space between the nozzle 6 and sleeve '0.
  • a sieve box it designed to serve as a receptacle for the substances to be dissolved, is arranged around the upper end of the mixing nozzle and located in a vessel 2' mounted on the upper end of the circulating tube 70.
  • a special remarkable feature of the improved apparatus is the absolute separation of the intense movement in the spaces which serve for mixing and distributing from the clearing or settling space in which the eifect of the jet apparatus makes itself felt only in a favorab e manner, that is to say in assisting the settling, a further remarkable feature being that accumulation of mud in the clearing vessel is absolutely avoided.
  • the distributing sieve g is preferably fixed to the lid of the apparatus, and the sieve box It is arranged so that it can be easily removed.
  • a central jet pump and mixing nozzle a circulating tube surrounding said nozzle with a clearance, a vessel surrounding said circulating tube and communication tion between said jet pump and said lower I tending through and beyond said circulating tube into the said upper vessel, communication between said jet pump and said lower vessel and a filter partition within said lower vessel above said communication.
  • a circulating. tube connecting an opening in the bottom of the lower vessel with an opening in the bottom of the upper vessel, a jet nozzle in the bottom end of said circulating tube, a jet pump and tubular mixing nozzle above said jet nozzle, said mixing nozzle extendin through and beyond said circulating tu e into the said upper vessel, communication between said jet pump and said lower vessel and adistributing discabove the upper end of said circulating tube.
