Definitions

  • the invention relates to a device for mixing powdery substances with liquids for the production of suspensions or solutions, in particular for mixing and preparing electrolyte powder with water, consisting of a induction bowl that can be filled with powder and a partial flow of the liquid and a downstream one with which Main part of the liquid feedable mixing tube, from where the liquid / powder mixture can be fed to different chambers.
  • Such processing plants are used for the production of liquid / powder mixtures in which the powder content is only a few percent or below 1% and in which special precautions are therefore necessary in order to produce a homogeneous mixture and around to maintain homogeneity even during the subsequent ripening or processing phase.
  • the induction bowl opens at its lower end into a horizontally extending mixing tube. It has the task, on the one hand, of bringing about the desired mixing of the two components, on the other hand of preventing the incoming liquid flow from splashing up into the induction bowl.
  • the water / powder mixture is passed into a first treatment chamber. From there, the mixture gradually reaches a second and possibly a third chamber.
  • the various chambers are designed to ensure that the mixture is sufficiently homogeneous and mature before it is removed from the last chamber.
  • the object of the present invention is to improve the known system in such a way that it is characterized by more cost-effective and compact expansion and, moreover, it guarantees a high degree of homogeneity of the mixture, both in terms of the powder concentration and in terms of the degree of maturity of the product.
  • the mixing tube extends approximately vertically and opens into an allotment channel, which is arranged above the partition between two chambers and that this allotment channel is pivotally mounted about an axis of rotation arranged in its upper region, which in turn is approximately parallel to Partition extends or is aligned with it.
  • the cross section of the metering channel is substantially larger than that of the mixing tube, so that the lower end of the mixing tube is free in the Allocation channel protrudes. This eliminates the need for a tight, flexible connection between the rigid mixing tube and the swiveling feed channel, and both line parts can be easily inspected from the outside and cleaned if necessary.
  • this design opens up the possibility of also allowing the overflow line from the induction bowl and, if necessary, a bypass line for the liquid to flow freely into the distribution channel.
  • the device according to the invention is also ideally suited for the mixing of chemically reacting components in which the formation of steam occurs due to the exothermic course of the reaction, for example when slaking quicklime
  • a development of the invention provides for branching off a partial flow of the liquid to be supplied and a water jet pump for suction of brothers from the chambers.
  • This water jet pump also conveniently opens into the distribution channel, so that when switching from one chamber to the other, the correct assignment is automatically obtained.
  • powder dust can also be extracted from the induction chamber with this or an additional water jet pump.
  • the feed pipe for the main part of the liquid does not as previously perpendicular to the lower end of the induction bowl, but instead ends at an acute angle in the mixing tube, such that the angle between the incoming line parts of the induction bowl and the loading tube is less than 60 °, advantageously about 45 °.
  • the feed channel be connected to a motorized swivel drive.
  • the swiveling of the feed channel can take place automatically when the chamber so far acted on has reached its maximum filling level.
  • the fill level can be monitored by level indicators, which automatically trigger the swiveling of the feed channel.
  • the mixing device consists of a large container which is divided by a partition 1 arranged in the middle into two adjacent chambers 2 and 3.
  • the actual dosing and mixing device is located above it. It consists of a induction bowl 4, to which the powder to be processed is fed from a storage container 5 by means of a horizontal dosing screw 6.
  • the induction bowl 4 is connected to a rinsing line 7, via which part of the liquid to be mixed with the powder reaches the induction bowl in order to convey the powder located there down into a mixing tube 8.
  • a feed line 9 opens into this mixing tube 8 for the larger part of the liquid to be mixed with the powder.
  • the mixture thus produced then passes into chamber 2 or 3, in which it is constantly mixed by agitators 10 and 11, respectively.
  • the structure described largely corresponds to the known mixing plants.
  • the mixing tube 8 does not run horizontally as before, but instead runs vertically and extends downwards directly from the outlet of the induction bowl and that the feed line 9 opens into the mixing tube at an acute angle.
  • the powder washed out of the induction bowl 5 is subjected to intensive shear stress and swirling.
  • this connection construction is considerably cheaper than the previously used four-way connection.
  • a pivotable metering channel 12 is arranged below the mixing tube 8, the outlet opening of which can be pivoted either into the left-hand chamber 2 or into the right-hand chamber 3. Its swivel mounting is arranged in the upper area so that its inlet opening is acted upon by the outlet of the mixing tube 8 regardless of the swivel position.
  • the distribution channel 12 has an approximately rectangular cross section and is mounted on its two narrow sides on the housing of the mixing device. It is pivoted (in FIG. 4 perpendicular to the plane of the drawing) by an electromotive swivel drive 13 which is controlled by the level controls 14 and 15 visible in FIG. 1. If, for example in FIG. 1, the maximum filling level is reached in the left chamber 2, the distribution channel 12 is automatically folded over to the other chamber 3. Likewise, the valve block 16 can also automatically automatically switch from one chamber to the other for the removal of the finished product.
  • all other supply lines for the liquid such as the overflow line 17 from the induction bowl and a bypass line 18, also open into the feed channel 12 through the liquid bypassing the mixing tube 8 into the chamber 1 or 2 is fed.
  • FIG. 5 A development of the invention is shown in FIG. 5. It is particularly suitable for mixing processes in which gases or vapors are generated in the chambers.
  • a suction line 19 is connected to the essentially closed chambers, which opens into a water jet pump 20. This water jet pump is fed by a branched-off partial stream of the liquid to be supplied. This partial flow and the entrained vapors then flow to the distribution channel 12.
  • the invention was described above using the example of a two-chamber container. Of course, the protection also extends to larger mixing devices in which three or four chambers are available through a further partition running perpendicular to partition 1.
  • the distribution channel 12 is then to be arranged at the point of intersection between the chambers and must be pivotably mounted in two mutually perpendicular planes so that its outlet opening can be pivoted into each of the chambers.
