Definitions

  • the invention relates to a centrifuge for separating solid-liquid mixtures, in which at least one thickened solid phase is at least partially discharged through at least one opening arranged below the liquid level, plate packs also being provided to influence the flow direction of the heavy phase.
  • a control device for opening and closing an outlet opening in the casing of a centrifuge is known, the control device being arranged outside the drum or the casing.
  • the control device mentioned is very complicated and susceptible to failure.
  • a centrifuge with plate packs is known from FR-A-1359356, but this device also has a complicated and uncontrollable discharge system for the thickened solid phase.
  • the object of the invention is to present a centrifuge which is improved with respect to the opening and closing of the openings arranged in the jacket, i. H. that the thickened heavy phase is controlled by a control device in accordance with controlled operating parameters such that the thickened heavy phase can be released in a controlled amount and / or amount per unit of time.
  • the object of the invention is achieved in that the centrifuge has a control device arranged inside the jacket for opening and closing the openings.
  • control device is equipped with a drive. In this way it becomes easily manageable, i. H. adjustable and jerky accelerations can be avoided.
  • the control device advantageously has a width that at least partially covers the opening and is preferably designed as a disk. This is a particularly simple, i.e. Cost-effective design of the device with low susceptibility to faults.
  • the jacket is cylindrical. This measure makes it particularly advantageously possible to enlarge the discharge area for the heavy phase laden with solids and also to subtract any quantity of the thickened heavy phase.
  • a plurality of control devices and openings, in particular nozzles, are arranged distributed on the jacket. This results in an increased sensitivity of the discharge control.
  • the invention is also expediently designed in such a way that the nozzle-like openings are controlled independently of one another.
  • a particularly useful embodiment of the device according to the invention provides that a plate pack spacers between the individual plates has with deflecting elements protruding beyond the plate ends. This measure gives aer separated heavy solids-loaded phase in a particularly simple manner a movement component parallel to the axis of rotation, but also parallel to the circumference of the jacket, so that the nearest outlet nozzle is reached in the shortest possible time. .
  • FIG. 1 An arrangement of the control device according to the invention in a separator is shown in FIG. 1.
  • the housing 70 of the separator consists, in a manner known per se, of the two housing parts 71 and 72 screwed together. In the area of the largest diameter, nozzle-like openings 73 are arranged which have a free one Allow passage of the heavy mud phase. To control this passage is in
  • the control element 75 configured according to the invention is arranged, which is set in rotation with a differential speed in relation to the housing 70.
  • the housing 70 is rotatably mounted with the hollow shaft 74 in the bearing 76, and on the other hand, the inner parts of the separator are rotatably mounted on the shaft 77 independently of the housing 70.
  • the shaft 77 and the hollow shaft 74 are supported one inside the other by the needle bearings 78.
  • the control device 75 is arranged in support arms 79, which in turn are firmly connected to the shaft 77.
  • the body 81 carrying the separator plates 80 is screwed and rotated firmly to the shaft 77, connected to the control device 75 on the same shaft, at a differential speed with respect to the housing 70.
  • the control device 75 covers the opening 73 in the position shown and closes it in the way already described. However, if, as a result of the relative movement, the recess 85 ah migrates past the opening 73, the latter is temporarily released and the accumulated sludge can escape from the housing 70.
  • both the hollow shaft 74 and the shaft 77 are each equipped with a separate drive disk 82 and 83. These are driven by a Vario gear 86 with the motor 87 with an adjustable speed difference via the V-belt transmission 88 and 89.
  • the turbidity is entered in a manner known per se in accordance with the arrow 90 through the feed pipe 91 into the interior of the body 81 carrying the separator plates 80, on the conically enlarged wall of which the Suspension is passed down and through the openings 92 in the conically widened distributor 93, from where the suspensions in a manner known per se enters the separation chamber of the separator.
  • the lighter phase reaches the outlet chamber 93 in the upper region of the separator and from there into the outlet pipe 94.
  • the amount of sludge discharged per unit of time is set on the one hand by the number and size of the openings 73 on the diameter of the separator housing 70, and on the other hand controlled by the type and design of the control device 75 and its recesses 85 via the differential speed.
  • Fig. 2 shows the control device according to the invention in a centrifuge in which three phases of different weights of solid-liquid mixtures and / or mixtures of liquids of different densities can be separated.
  • the cylindrical housing 70 of the centrifuge consists of the two housing parts 71 and 72 screwed together. In the area of the largest diameter, a number of nozzle-like openings 73 are arranged on the jacket 70, which enable the heavy phase to pass freely.
  • the centrifuge also has special internals 80 which serve to increase the separating effect.
  • the control takes place as described for FIG. 1, by means of one or more Control devices 75, which are arranged in support arms 79. It is also part of the invention that the control of the individual nozzle-like openings 73 can take place independently of one another by setting different differential speeds of the control devices 75 with respect to the housing 70.
  • the three-phase mixture is entered in a known manner according to the arrow 90 through the feed tube 91 into the interior of the internals 80 designed as a plate pack, which is carried by the body 81, on the conically enlarged wall of which the suspension is conducted downward and through the openings 92 in reaches the conically widened distributor 93, from where the three phases reach the separation space of the centrifuge in a manner known per se.
  • the medium-heavy phase enters one Outlet chamber 104 and from there into the outlet pipe 105, while the light phase rises between the plates 97 of the plate pack 80 and is drawn off via the outlet pipe 106.
  • FIGS 3, 4 and 5 show in detail the configuration of the plate internals 80 when the device according to the invention is designed with a cylindrical jacket.
  • deflecting elements 99 are provided, for example by extending the spacers 96 between the individual plates 97 beyond the plate ends 98. By bending the deflection elements 99 in a suitable manner, the movement towards the nearest outlet nozzle 73 is predetermined for the heavier phase.
  • the upper edges of the ends 100 of the deflecting members 99 are rotated about their center of gravity axes 101 in the direction of rotation 102 by an angle ⁇ ⁇ between 0 and 90 °, preferably 60 °, so that the axial flow component is amplified .
  • the deflection elements 99 are bent in the flow direction 103 by an angle Beta / 3 between 0 and 90 °, preferably between 45 and 60 °.
  • a kink or bend of the deflection elements 99 with respect to the axis of rotation can also give the flowing heavy phase a movement component parallel to the axis of rotation and is also part of the subject matter of the present invention.
