Definitions

  • the invention relates to a paste container with a follower plate sealing the open side of the container, to which a multi-flight agitator propeller is attached such that it can be rotated a short distance below the follower plate about an axis projecting through it centrally, and a removal device with an external drive with the paste can be removed from the container through an opening in the follower plate.
  • the invention particularly relates to paste containers for pseudoplastic or thixotropic pastes with a device for reducing their viscosity and for removing them.
  • Paste-like detergents are becoming increasingly important and are being used more and more in laundries. With paste-like detergents, the advantages of powder detergents, in particular their high active substance contents, can be guaranteed without having the disadvantages of liquid detergents, in particular their water or solvent contents.
  • Pasty detergents of this type are frequently pseudoplastic or thixotropic pastes, in particular highly viscous detergent pastes, which are mainly used in commercial laundries.
  • Structurally viscous or thixotropic pastes have the property that their viscosity is reduced when exposed to mechanical shear forces, for example when stirring, shaking or under the influence of ultrasound, and they solidify again after the mechanical stress has been interrupted. This means that this property, that the viscosity of such substances decreases under the influence of increasing shear stress or shear rate, can be used to facilitate handling.
  • Pasty detergents, especially high-viscosity pastes also lead to a special problem in their packaging and handling.
  • German patent application P 43 32 850 describes a paste container with a removal device which is suitable for receiving and removing highly viscous pastes. It consists of a cylinder that is open on one side and a follower plate that is movably arranged on the open side of the cylinder, and has a removal device for removing and transporting the paste.
  • a motor with a gear is arranged on the follower plate, on the axis of which a multi-flight agitator propeller is attached in the center of the follower plate. This is located slightly below the follower plate and can rotate freely in the paste, whereby the viscosity of the thixotropic paste is reduced due to its shear stress.
  • the paste which is easily conveyed as a result, is fed through the stirring blade to a removal device which conveys the paste through an opening in the foam plate and has an external drive.
  • This device has the disadvantage that it is very complex.
  • the separate drives for the impeller and the removal device are expensive and, due to their space requirement, cause difficulties in the arrangement above the paste container.
  • the technical problem on which the invention is based is to further develop the known paste container with removal device in such a way that it leads to lower manufacturing and operating costs and allows a more compact construction.
  • This problem is solved in that the impeller and removal device have the same drive in a generic paste container.
  • the paste container according to the invention has the advantage that the use of the same drive for agitator and removal device to a clear
  • the manufacturing and operating costs become cheaper and the limited space above the paste container can be used better and more clearly by eliminating an aggregate. Since the thixotropic paste has to be stirred only to reduce the viscosity and to promote it, if paste is also to be removed, the combination of the drives of the impeller and the removal device is particularly suitable.
  • This drive combination is particularly favorable in an embodiment in which the removal device has an axis of rotation of a conveying element which is arranged about a axis of rotation perpendicular to the follower plate. This is particularly advantageous to solve by using a screw or screw pump that conveys the paste supplied by the stirring propeller to the outside.
  • the removal device is arranged off-center, the distance from the axis of rotation of the agitator blade can be bridged in a simple manner by intermeshing gear wheels or a belt drive. If the removal device is arranged centrally on the follower plate, the impeller shaft or hub can be formed in a particularly advantageous manner by the extension of the conveyor element shaft on the screw rotation axis.
  • the feed line is designed to be closable by a shut-off element, for example by a ball valve
  • the delivery flow can be briefly interrupted in a particularly advantageous manner until an approximately constant delivery rate has been established.
  • the conveyor element 6 has a central conveyor channel 7, in which a screw conveyor element 5 rotates.
  • the common drive of the impeller 4 and the screw conveyor 5 is the motor 8, which is slidably attached and guided via a holder on a guide 11.
  • the combination of the removal device 6 and the impeller 4, including the common drive 8 can be moved vertically if the follower plate 2 follows the level of the thixotropic paste 12 which drops when removed.
  • the ventilation screw 10 must be opened if the follower plate 2 is to be removed after the paste container 1 has been emptied.
  • the delivery rate of the removal device 6 is dependent on the speed, but also on other influencing variables such as channel diameter, screw volume and pitch.
  • the respective speeds can be adjusted to the specific functional requirements via the design of the transmission between the shafts of the removal device 6 and the impeller 4. If the shaft of the impeller 4 is formed by the extension of the conveyor element shaft, the impeller 4 rotates at the same speed as the removal device, so that the viscosity of the thixotropic paste is determined in this way. In this case, the speed of the impeller 4 should be adjusted with regard to the desired consistency of the paste.
  • the funding volume is determined on the basis of the determination of the other influencing factors.
  • a feed, not shown, to a dosing injector, also not shown, can be arranged at the opening 9.
  • the feed line to the injector can be temporarily closed using a ball valve.
  • the injector must overcome a certain back pressure after opening the water valve before it is at full capacity. This can cause water to be pressed into the paste line for a short time, which water gets between the ball valve and the paste pump with extremely short dosing times, whereby the pump cannot build up its full pressure. If the metering system is not used for a longer period of time, hardening with the highly alkaline paste can take place here, which can lead to blockages of the injector.
  • the ball valve also makes it possible to flush the hose lines in the closed state without coming into contact with the paste.

Abstract

L'invention concerne un réservoir à pâte présentant une plaque suiveuse (2) obturant hermétiquement le côté ouvert du réservoir. Sur la plaque suiveuse est monté un agitateur à plusieurs pales (4), de telle façon qu'il soit entraîné en rotation à faible distance au-dessous de la plaque suiveuse (2) autour d'un axe (5) émergeant au milieu de cette plaque (2). Le réservoir à pâte présente un dispositif de prélèvement (6) doté de moyens d'entraînement extérieurs (8), au moyen duquel la pâte (12) peut être retirée du réservoir (1) par un orifice ménagé dans la plaque suiveuse (2). Les pales d'agitation (4) et le dispositif de prélèvement (6) ont les mêmes moyens d'entraînement (8). Le réservoir à pâte convient en particulier pour la réception de pâtes thixotropes.
