Definitions

  • the present invention relates to a flow mixer for mixing fine-grained and dusty solid bodies with water, e.g. for mixing of fly ash and bottom ash with water in a continuous manner.
  • the presently known devices for mixing ash with water in a continuous manner include constructions of the mixer, flushing, and ejector type and cyclically operating mechanical mixers.
  • Mixers are composed of a chamber in which ash flushed by a water stream is supplied by gravitation.
  • Such flushing apparatus comprises a passage through which water flows continuously, and a stub-pipe above the passage, through which fly ash is charged.
  • Mixers and flushing apparatus serve for mixing ash with water in concentrations of from several parts up to a dozen or so parts of water per 1 part of ash.
  • Cyclically operating mixers are composed of a mixing chamber provided with one or several rotational shafts on which mixing members are mounted, which are in the form of leaves, blades or bars performing conforming or contrary rotary motion.
  • the mixer mixes the received components and after a preset time it is emptied of the obtained suspension.
  • the mixing cycle restarts from the beginning.
  • the concentrations achieved are of the order of 0.5 up to several parts of ash per one part of water.
  • An object of the invention is to provide a continuously working mixer which does not require retention tanks of big capacity, and does not require mixers other than one working and one stand-by mixer.
  • a flow mixer for continuous mixing of fine-grained or dusty materials with water, characterised by: a batching feeder for supply of the material; a moisturizing chamber arranged to receive and moisten the material from the feeder; a homogenizing chamber arranged to receive the material from the moisturizing chamber and to provide a more homogeneous mixture; and a fluidization chamber arranged to receive the material from the homogenizing chamber and to add further liquid for producing a fluidized mixture.
  • the mixer according to another aspect of the invention is composed of a feeder batching dry ash in a continuous manner, a moisturing chamber which can be provided with a slow-speed mixer of arbitrary design, a homogenization chamber and a fluidization chamber. Outlets from particular chambers join directly the inlet to the subsequent chamber.
  • the homogenization chamber and the fluidization chamber are placed axially one after the other and have a shaft in common on which homogenizing-mixing and pushing-through members in the form of leaves, blades and worms are mounted.
  • the homogenization chamber is in the form of a cylinder and is set horizontally.
  • the fluidization chamber is in the form of the frustrum of cone or in the form of subsequently placed cylinders of increasing diameters.
  • the normal section of the fluidization chamber increases continuously or step-like in the direction of the mixture flow.
  • Members mounted on the shaft have the flat surfaces inclined at an angle of 5° - 30° in relation to the normal plane of the shaft axis.
  • stub-pipes for connecting water pipelines and stub-pipes of inspection holes are built.
  • a stub-pipe enabling the supply of granular bottom ash is connected to the jacket of the fluidization chamber.
  • the fluidization chamber is closed by a cover wall which has in its upper fragment an outlet stub-pipe.
  • an outflow control element is built-on.
  • the cover wall has a tapping stub-pipe.
  • the shaft passing through the homogenization and the fluidization chambers in places of passing through the small and big cover walls have a water seal.
  • the shaft of the batching feeder, of the slow-speed mixer in the moisturing chamber and the working shaft in the homogenization and fluidization chambers have separated drives.
  • the mixer has a batching feeder 1, a moisturing chamber 2 in which a slow-speed mixer 3 driven by a drive unit 4 is provided.
  • the outlet of the moisturing chamber 2 joins an inlet 5 of an homogenization chamber 6 in which a shaft 7 is provided driven by a drive motor 8.
  • a fluidization chamber 10 is connected, in which the shaft 7 carries mixing and advancing members 11.
  • stopper or blocking members 12 On the jacket of the fluidization chamber 10, stopper or blocking members 12, a stub-pipe 13 to supply bottom ash, and water stub-pipes 14 are provided.
  • the larger end wall 15 of the fluidization chamber has an outlet stub-pipe 16 with an outflow control element 17, and a tapping stub-pipe 18.
  • the fluidization chamber 10 has a sample collection stub-pipe 19.
  • the moisturing chamber has a water stub-pipe 20 and an inspection manhole 21.
  • the mixer operates in the following way:
  • the batching feeder 1 having its own drive unit as illustrated, feeds dry ash to the moisturing chamber 2.
  • water is supplied to the said chamber 2 through the stub-pipe 20.
  • ash is wetted and mixed by means of the mixer 3.
  • the mixture which is still very heterogeneous passes through the inlet 5 to the homogenization chamber 6 wherein it is pressed in order to remove air, and mixed and forced through by the worm segments 9.
  • the mixture is homogenized and gains a dense plastic consistency.
  • the mixture passes to the fluidization chamber 10 in which water supplied by the stub-pipe 14 causes its conversion into the fluid state.
  • the mixture according to the invention can be applied both in hydraulic transport systems and in technological lines at the preparation of mixtures and suspensions of different media and substances.
