Definitions

  • Loop reactor with a reactor housing, with a mixing chamber and an inlet in the area of the bottom of the loop reactor and one Outlet in the area of the head of the loop reactor for the material to be processed Well, with a stator and a rotor driven by a motor, the stator and rotor predominantly in that facing the second head Part of the mixing chamber are arranged, stator and rotor each have at least one hollow cylinder provided with longitudinal slots, the Hollow cylinder of the stator and that of the rotor concentric and alternating interlock and the stator a guide tube protruding into the mixing chamber has, in which a screw conveyor is arranged.
  • Such a loop reactor is known from DE 39 19 828 and is used for processing liquids of different viscosities.
  • Such loop reactors play particularly in food process engineering a major role, e.g. for mixing, emulsifying, homogenizing, Suspend, beat, stir until smooth, undergo, etc. from to processing liquids and possibly solids.
  • a screw conveyor intended for the transport of the goods also called dynamic mixer
  • the rotating hollow cylinders the rotor and the stator worked the good.
  • These slotted ones Hollow cylinders cause e.g. a reduction in droplets in emulsions.
  • Loop reactors in which the rotor and screw conveyor are known are also known are attached to a common shaft. With these loop reactors the shaft is passed through the bottom of the reactor and stored outside the reactor housing. There is a large distance between the hollow cylinders of the rotor and the stator on the one hand and the camp on the other hand. This is a disadvantage as the largest are based on the Forces and moments acting on the shaft in the area of the hollow cylinder, i.e. on unsupported, free end of the shaft, which occurs especially at high RPM leads to problems. Remedy was in another Storage found in the area of the hollow cylinder, but this caused problems cleaning the mixing chamber.
  • the invention is therefore based on the object of proposing a loop reactor, which is easier to construct and assemble and less in operation prone to failure and more cost-effective and can also be operated at high speeds is.
  • This object is achieved in that the screw conveyor and the rotor on a common motor-driven one Shaft are attached and that the shaft through the head of the loop reactor passed through and rotatable in or above the head is stored.
  • the inlet is in the bottom of the loop reactor provided, advantageously the guide tube for the screw conveyor in the area this admission ends.
  • the bearing can face the shaft in or on the head Cavities in the reactor housing which contain the material to be processed, be sealed.
  • the seal can advantageously be a Act mechanical seal.
  • the inlet, the guide tube, the rotor and the stator and baffles attached to the stator may be arranged centrally.
  • a loop reactor (FIG. 1) has a reactor housing 1 with a mixing chamber 2 on. This can be done through an inlet 3 or through an outlet 4 Enter the material to be processed into the mixing chamber 2 of the loop reactor or discharged from the mixing chamber 2
  • the mixing chamber 2 itself has a cylindrical shape, and the inlet 3 is in the bottom of the Reactor housing 1 provided.
  • a stator 5 projects into the mixing chamber 2, which is firmly connected to the reactor housing.
  • the stator has two Hollow cylinder 15, the cylinder walls are provided with longitudinal slots 9 are.
  • the stator is provided with a guide tube, which is almost extends over the entire length of the mixing chamber 2. Protrudes into this guide tube a shaft 10, which through the opposite of the inlet 3 Head of the reactor housing is led out of the reactor housing 1.
  • the shaft is in the bearing 11 provided above the head rotatably mounted.
  • a rotor 8 is attached to the shaft 10.
  • This rotor points two hollow cylinders 16, which like the hollow cylinder 15 of the stator Longitudinal slots 9 are provided.
  • the hollow cylinder 15 of the stator and 16 of the Rotors interlock with each other, arranged concentrically (see also Fig. 2). Furthermore, is on the end protruding into the guide tube 6 the shaft 10 is attached to a screw conveyor 7.
  • On the outside of the Stator or the guide tube 6 is a front by means of a guide plate 14 Collection chamber 17 formed (see also Fig. 3).
  • This front collection chamber 17 is ring-like and over the entire circumference in the direction of Inlet 3 of the loop reactor opened.
  • In the opposite Recesses are provided in the wall of the front collecting chamber 17, to which pipes 13 are attached.
  • These tubes 13 connect the front Collection chamber 17 with one in the cover of the reactor housing 1 provided rear collection chamber 12.
  • This rear collection chamber 12
  • the material to be processed passes through inlet 3 in the reactor housing 1 into the loop reactor of the delivery pressure into the guide tube 6, where it is conveyed by the screw conveyor 7 detected and transported upwards.
  • the upper end of the guide tube 6 goes in a first hollow cylinder 9 of the stator above the guide tube 6 upwards is limited by the rotor 8, the good due to the delivery pressure pressed through the longitudinal slots 9 in the hollow cylinder 15 of the stator.
  • a first hollow cylinder rotates on the outside of the longitudinal slots 9 of the rotor 8.
