Definitions

  • the invention relates to a metering device for introducing powdery, agglomerated, solid, pasty and liquid agents from storage.
  • the device can be used both in the home and in business.
  • the device is particularly suitable for dosing detergents, cleaning agents and detergents in the area of commercial cleaning.
  • Detergents used in the area of machine dishwashing are used in powder or agglomerate or granule form, as a liquid, as a cleaning block or in paste form.
  • Each of these forms of cleaner has special advantages and disadvantages and is selected and used by the customer according to the circumstances.
  • the different forms of application of the cleaning agents require appropriately adapted dosing systems.
  • Powdery or agglomerated or granulated cleaners are dosed according to the dispenser principle or the rinsing principle.
  • Liquid detergents are usually added to the cleaning solution with the aid of dosing pumps.
  • Block-shaped cleaners can be dosed according to the rinsing principle.
  • each type of cleaner has a special dosing system. For the user, this means that when changing the cleaner form, the dosing system must also be replaced.
  • the object of the invention is to create a metering device which can be used universally for all forms of presentation of the cleaning agent.
  • the dosing device is intended in the same way for liquid and pasty, powdery and agglomerated or granulated detergents - even in the caked and clumped state of the respective detergent - as well as for block-type detergents Seal against accidental leakage of the cleaning agent and against the ingress of moisture in the idle state, ensure problem-free handling with detergent caked and clumped as a result of improper work and enable high detergent emissions when pre-dosing.
  • the solution according to the invention is characterized by a metering funnel with a spacer tube that adjoins its outlet opening and ends at the free end in an annular sealing edge, and by a metering plate attached to the free end of a lifting shaft guided through the metering funnel with a circumferential, conically sealing by actuating the lifting shaft Sealing edge of the spacer tube to be created.
  • breakers are placed on the inner wall of the metering funnel and / or spacer tube and on the lifting shaft, preferably approximately perpendicular to the longitudinal direction of the shaft. Furthermore, it can be advantageous if crusher standing approximately parallel to the longitudinal direction of the lifting shaft is provided on the metering plate.
  • the conical sealing system according to the invention at the outlet of the metering funnel enables a high level of tightness to be achieved with relatively low forces.
  • the metering opening or the metering gap can be easily adjusted by lifting and lowering the lifting shaft in such a way that the required amount of detergent must be set both for normal cleaning operations and for pre-metering.
  • the dosing device according to FIGS. 1 and 2 contains a dosing funnel 2 with outlet nozzle 3 as well as with a spacer tube 5 inserted therein, in particular with screws 4, and one to the free end of a tube guided through the dosing funnel 2 within a cylindrical or cuboid-shaped vessel designated as 1 Stroke shaft 6 attached dosing plate 7.
  • the dosing plate 7 has a circumferential sealing edge 8, which is conically sealed by lifting the lifting shaft 6 in the direction of arrow 9 To be brought into contact with an annular sealing edge 10 provided at the free (lower) end of the spacer tube 5 (FIG. 3).
  • the lifting shaft 6 is assigned a drive housing, designated overall by 11, for a lifting movement and, if appropriate, a rotary movement to be carried out simultaneously with the lifting movement.
  • a collecting funnel 12 with a drain pipe 13 and possibly a siphon 14 is provided for the metered product quantity.
  • the centerpiece of the present metering device is the cleaner outlet according to FIG. 3, designated overall by 15.
  • This essentially consists of the spacer tube 5 with the shaft 6 running parallel to the longitudinal axis and the metering plate 7 with a sealing cone.
  • the shaft 6 can be driven by one or more motors; In the exemplary embodiment, the drives are designed such that the 6 can also perform a rotary movement about the longitudinal axis 16 in addition to a stroke movement in the direction of arrow 9.
  • the metering plate 7 is attached to the lower end of the shaft 6 with the aid of a screw device 17.
  • the metering plate 7 should have a sealing edge 8 running obliquely to the longitudinal axis 16 towards its outer edge.
  • Crushers 18 are provided on the inner wall of the spacer tube 5 and crusher 19 on the shaft 6. Crushers 20 can also be attached to the metering plate 7. In contrast to the crushers 18 and 19, however, the crushers 20 should run parallel to the longitudinal axis 16.
  • a commercially available cleaner containing caustic alkali was stored in a closed container at room temperature and the equilibrium pressure of the water. Due to the high content of strongly hygroscopic alkaline components, the cleaner becomes moist and baked after a few hours. If, on the other hand, the same cleaner was stored under the same conditions in a vessel 1 according to FIGS. 1 to 3 with the metering plate 7 moved into the sealing position, the product was still free-flowing even after 100 hours of storage.
  • a cleaner containing caustic alkali was deliberately converted into larger lumps.
  • the shaft 6 is held in the drive housing 11 in a flexible coupling 21 in such a way that the shaft 6 is freely movable at the bottom in order to avoid tilting in the case of clumped or caked cleaners.
  • the lifting shaft 6 is mounted in the drive housing 11 in a ball or brass bushing 22 and sealed with a sealing ring 23 against the interior of the metering device 1.
  • a rotary drive 24 and a lifting drive 25 which serve to set the metering plate 7 on the one hand in rotation and on the other hand to have a lifting movement carried out.
  • the rotary drive 24 has a motor with bevel gear drive 26 for transmitting the motor movement to the lifting shaft 6.
  • the lifting drive 25 according to FIGS. 1 and 2 has a motor with a stroke eccentric 27 placed on its drive.
  • the induction or collecting funnel 12 with a drain pipe 13 connected to it and optionally a siphon 14 Dosing vessel 1 transferred product transferred.
  • the funnel 12 At the upper end of the funnel 12 there are, preferably arranged in the ring, nozzles 28, with the aid of which water or another suitable liquid can be sprayed into the funnel 12, for example controlled by a solenoid valve 29, in order to also adhere product adhering to the funnel walls to transfer the drain pipe 13.
  • the metered product is passed into the respective dishwasher via the outlet pipe 13 designed as an outlet nozzle.
  • a water barrier is built up in the drain pipe 13 and thereby prevents vapors escaping from the machine from entering the drain pipe 13 or the funnel 12 and leading to caking of the metered product on the pipe wall or the like.
  • 6 and 7 show a further possible drive unit for the shaft 6, which is denoted overall by 31 and manages with a single motor with left / right rotation for the simultaneous rotation and lifting or lowering of the metering plate 7.
  • the shaft 6 is driven by a motor, not shown, with a gear attachment 32.
  • the transmission takes place with the aid of a drive coupling 33.
  • the shaft 6 moves in a partial thread 34 with an elongated hole 35 (FIG. 7) that is located in a control slide 36.
  • the control slide 36 is actuated via a solenoid 37 with an adjustable return spring 38.
  • the solenoid 37 releases the shaft 6 via the control slide 36, so that the metering plate 7 at the lower end of the spacer tube 5 releases the maximum metering opening.
  • a sealing tube 41 is provided which, when the metering gap is closed (between the sealing ring 43 and the sealing edge 8), blocks the outlet of the liquid or pasty cleaner. A leakage of liquid cleaner between the two pipes 5 and 41 is prevented by a further sealing ring 44.
  • the sealing tube 41 is pushed completely over the spacer tube 5 and is thereby deactivated (FIG. 8).
  • the sealing tube 41 is extended so that the sealing ring 43 together with the sealing edge 8 of the dosing plate 7 performs the sealing function (FIG. 9).
  • Rotation of the metering plate 7 is not in itself necessary for metering liquid cleaners. However, it does no harm either. It can therefore be easily metered with a dosing plate 7 to be rotated, liquid or pasty detergent, if for universal applicability the dosing device should be designed for use with both solid and liquid cleaning agents.
  • the metering device For use in block-shaped cleaners, the metering device according to FIGS. 1 and 2 has a grid insert 45 with a mesh size which prevents the block cleaners from falling through. Block-shaped cleaners therefore do not come into the area of the crusher 18 to 20 according to FIG. It is not absolutely necessary for the cleaner blocks to be flooded with water. The blocks can be sprayed through the water supply using nozzles (not shown). Finally, the detergent solution produced by introducing water can be metered like in an outlet metering device with the metering gap open, that is, with the metering plate 7 lowered. The fill level in the metering funnel 2 can be measured here - as in the other applications - with the aid of a light barrier (FIG. 1) consisting of a light-emitting diode 47 and a photo cell 48.
  • a light barrier FIG. 1
