Definitions

  • the invention relates to a batch mixer, in particular a high-speed mixer for mixing feed, flours and. Like. According to the preamble of claim 1.
  • US-PS-4043540 discloses a tiltable paddle mixer with spiral mixing elements rotating in a trough.
  • a comparable construction can also be found in US-PS-4509860 and US-PS-3273863. They are particularly suitable for dry mix.
  • a stirrer for mixing feed according to DD-PS-262961 shows a mixing drum with a horizontally arranged stirrer, on which vertically standing and straight stirrer arm segments are arranged, which carry mixing strips at their ends. Plate-shaped additional mixing tools are releasably attached in the middle between the segments.
  • a mixing unit with a cylindrical mixing container is known from CH 648767.
  • a rotatable mixer shaft, to which groups of mixer arms with mixing plates located thereon are fastened, is arranged in the longitudinal axis and almost horizontally. The direction of action of the mixing plates is opposite in groups.
  • the object of the invention is to avoid the disadvantages of the known prior art, a high-speed mixer for feed and. To create the same, which enables a quick and residue-free (sanitation-appropriate) emptying of the mixing container and requires no ventilation or recirculation.
  • the batch mixer consists of the main assemblies mixing tank 1, base group 2 and drive section 3 with the corresponding control units.
  • the mixing container 1 and the base group 2 are only connected to one another by screw connections, which greatly simplifies service and sanitation.
  • the mixing container 1 can be made of both stainless and normal steel.
  • the inner surface of the mixing container 1 is smooth and contains no stiffeners or other internal elevations.
  • a service flap 4 is arranged on the side, and an inlet for the material to be mixed is arranged at the top. All seams are provided on the outside of the mixing container 1.
  • the l-d ratio of the mixing container 1 is close to one (smaller possible).
  • a mixing rotor 6 is mounted in the mixing container 1. It is driven by the drive 3.
  • a plurality of mixer arms 7 are attached to the mixing rotor 6 with fixed paddles 8 which are known per se.
  • the mixer arms 7 are shrunk into a clamping shoe 9, the clamping shoe 9 being fastened to the mixing rotor 6 by means of a clamping connection.
  • flaps 10, 11 are arranged as part of the bottom group 2, which are each pivotable about a bearing 12 or 13.
  • Per mixing container 1 itself is open in this area.
  • the flap opening extends from the front wall to the front wall and has no webs on the sides or in the middle that prevent the flow of product.
  • a bolt 15 mounted in a shaft 14 with a pressure roller 16 is pivotably arranged in the middle between the flaps 10, 11.
  • the flaps 10, 11 are provided with a seal over their entire length in an overlap region 17.
  • An inflatable sealing tube 18 seals the opposite flap side.
  • the flaps 10, 11 are actuated by means of a fluidic auxiliary drive, not shown.
  • the bolt is force-applied in the center, the control is delayed by means of a solenoid valve.
  • a force adjustment is given by means of slotted holes.
  • the flaps 10, 11 protrude in the longitudinal direction beyond the wall of the mixing container 1 (sanitation).
  • a sheet 19 closes residual spaces between the mixing container 1 and the base group 2 and also serves as a cable channel u.
  • the goods to be mixed are introduced into the mixing container 1 via the inlet 5 and subjected to the mixing process.
  • the flap 10 and then the flap 11 are opened by pivoting the bolt 15 (previously venting the air hoses 18).
  • the valve-like emptying position of the flaps 10, 11 (opening smaller than the slope angle) allows the emptying of the mixing container 1 in a controlled manner, so that no separate venting or recirculation of air is necessary in the intake channel, not shown.
  • the flaps 10, 11 are closed, the flap 11 is first pivoted in and then the flap 10.
  • the pressure roller 16 presses against the overlapping point of the flaps 10, 11 and closes them securely.
