Definitions

  • the invention relates to an agitator for suspending intermittent solids and liquids that would separate under the action of gravity in a storage container.
  • Stirring is a process in which liquids are mixed together or in which gaseous, liquid or solid bodies are distributed (or also dissolved) in liquids.
  • Stirring plays an important role in the chemical, pharmaceutical, food industry, raw material and water treatment as well as in environmental protection and farm technology.
  • the goal can be the production of a homogeneous system, the acceleration of mass or heat transfer or chemical resp. be a biochemical reaction.
  • the stirring processes can be carried out either in pipes or in containers, tanks or basins. In containers of all kinds, the necessary energy is usually supplied by stirrers rotating in the liquid. With these arrangements, a wide variety of processes are possible depending on the physical states of the components involved. Liquid and solid components are stirred to dissolve, extract, float, crystallize, displace solubility and suspend.
  • agitators There are a whole number of agitators according to the preamble of claim 1 are known, which are known as anchor stirrers, finger stirrers, ribbon stirrers and screw stirrers in the textbooks of chemistry, machine and apparatus construction or standards (anchor stirrers, DIN No. 28143, DIN No. 28142 / 43). All of these agitators are arranged in vertical containers so that their shaft is arranged in the container axis. Due to this arrangement, the drive is attached to the roof of the container when the container is closed and to a bridge-like structure on an open container.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of creating an agitator for suspending intermittently occurring solids and liquids which would separate under the influence of gravity in a basin or storage container, by distributing them into one another into a system, that the energy in the form of shear and transport forces is supplied by the rotary movement of a paddle stirrer, the axis of rotation of which is mounted eccentrically to the middle of the container bottom, and which is at an acute angle to the liquid level at rest, and whose paddles form the outer surface of a cone during rotation that its surface line runs parallel to the bottom of the container at a short distance. almost touched this.
  • the drive is supported or arranged on the edge of the container wall.
  • the advantages achieved by the invention are essentially to be seen in the fact that no additional supporting structures are required for the storage of the agitator in order to install an agitator which is an extremely slow-running machine and therefore works with high efficiency.
  • the proposed agitator generates the highest shear and transport forces in the bottom area of the pool, but covers the entire depth of the fill level with its paddles.
  • the agitator can be built in such a way that its paddles fold themselves automatically when they stand still.
  • This embodiment of the invention has the advantage that the stirring operation can be carried out intermittently, ie after each operating interval there is a break in operation which leads to segregation of the components and thus to deposits of the solids.
  • an agitator for suspending intermittently occurring solids and liquids, which would separate under the action of gravity is shown, which in its basic structure consists of a bearing block 1 with an integrated bearing, an agitator shaft 2, the preferably consists of a rectangular hollow steel, from a drive unit 3, which consists of a drive motor and reduction gears, and from hubs 4, in which the spokes 5 are fastened, and at the ends of which the paddles are seated.
  • the round pool wall 9 forms with the floor 8 the pool, the center 7 of which is marked. 1 finally shows the water levels 10, 11, 12, corresponding to a low, medium and full level of operation.
  • the foldable version of the agitator is shown analogously to Fig. 1, which in its basic structure of the bearing block 1, the agitator shaft 2 and the drive 3 and the hubs 25, 26 provided with joints, which the paddles 6th ', 6 ", 6''' and the spokes 5 through the joints 31 ', 31'',31''.
  • the telescopic tubes 32 ', 32'' are attached to the hubs 25, 26 and hold the compression spring 34
  • the compression spring 34 is in the open state as a result of the rotation of the stirrer 36 or due to the centrifugal forces acting on the paddles 6 ', 6 "", 6 "”
  • the foldable stirrer is in the idle state and therefore folded.
  • the compression spring 34 is in an approximately relaxed state.
  • the contents of the full pelvis have segregated by creating layers of different densities from the liquid level against the pelvic floor.
  • three layers of different density are indicated, with the deposits 40 being followed by a layer of the heavier suspended matter 42 with the layer of the lowest density 43.
