Definitions

  • This invention relates to a device for the continuous mixing of at least two materials of which at least one canbe pumped, a tank being used for the mixing process in-which the material to be mixed is caused to circulate by means of a feed pump.
  • part of the materials to be mixed are withdrawn from the surface at one comer or section of the tank and reintroduced centrallyin the vicinity of the tank bottom.
  • the circulation of the mixture due to part ofthe material being returned to the tank in the form of three streams, is not controlled, 'the mixing effect is not uniform, and there is no certainty that the entire material particupates in' the circulatory movement.
  • the object of the present invention is to produce an expedient device for such processes whereby the pumping power required per unit throughout can be considerably reduced when compared with that required with conventional devices.
  • this problem is solved in that at least a part of the fresh material which flows to the mixing device is continuously passed into the mixing tank by way of a central supply pipe, the outlet of which is constructed in the form of a pressure nozzle that is located only slightly above. the'bottom. of the mixing tank which uniformally diverts the flow which is discharged from the nozzle radially in all directions.
  • the fresh materials that are to be mixed flow under pressure in the direction indicated by the arrow 1 through a supply pipe 11 towards the mixing device and by means of a supplydevice 2, hereafter briefly referred to as a pump, are conveyed through a feed pipe 5 into the mixing tank 4.
  • a supplydevice 2 hereafter briefly referred to as a pump
  • supply pipe 5 is constructed in the form of a pressure nozzle 6 with a restricted discharge section and is located slightly above the bottom of the mixing tank4.
  • the jet from the noule impinges against the bottom of the tank where-it is diverted radially in all directions in a uniform manner.
  • the material in the tank is thus subjected to a rotationally symmetrical circulatory movement with a return flow to the starting point along closed flow paths which are indicated by the arrows 8.
  • the mixed material emerges from the tank by way of a discharge pipe 7. Due to the influence of the'lateral discharge the circulatory movement is transformed into a spiral movement, the axis of the spiral being arcuate.
  • the throughput or travel of the material can be controlled in a suitable manner.
  • a device can be provided to vary the amount of material passing through the supply pipe 11 to the mixing tank or by varying the speed of the feed pump 2.
  • connection pipe 3 By means of the connection pipe 3 it is possible to influence the mixing intensity of the device in a very simple manner. If the output of the pump is kept constant, it is only necessary to vary theamount of fresh material that is supplied to the mixing device. If this amount exceeds the output of the pump very considerably, then a large part of the material will pass through the connection pipe 3 into the tank and the throughput or capacity of the device is increased but the mixing intensity is diminished. As the supply of material decreases, the part of the material which is directly bypassed into the tank decreasesand is finally zero when the amount of material supplied to the tank exactly corresponds to the output capacity of the pump. The mixing intensity has then increased and no more material flows through the connection pipe even when the throttle valve 10, located in pipe 3, is
  • the throttle valve '10 enables an additional individual adjustment to be obtained in order to accommodate various operatingrequirements so that very flexible hydraulic conditions can be achieved.
  • the described device serves primarily for materials that can easily be mixed, and itis characterized by its high efficiency, because depending on'the materials it is desired to mix and the required mixing intensity an optimum adjustment can be obtained whereby only a minimum amount of power per unit throughput is required.
  • -l.- Devicefor continuously mixing at least two materials, at least one of which can bepumped, comprising a feed pump, a
