From the annular space 33 flows by means of a Pump 36 fed from the reservoir 1 through the feed line 34 Liquid 2 through the passage openings 35 into the cylindrical Section 27 of the feed connector 13. It runs there on the inner wall 37 of the cylindrical section 27 down into the funnel-shaped Section 26. The downward flowing solid 38 is thereby from the liquid 2 running off on the inner wall 37 is completely enveloped.
- the Liquid 2 is the mixing machine 4 in the feed pipe 13 below Gravity fed.
- the solids metering device 29 has a funnel 40 which either has a volume that holds the entire batch of solid 38 is sufficient or the predetermined amount of solid is fed continuously during a complete mixing cycle. To the Dosing accuracy of the solid dosing device 29 is not special high demands. The dosing device only has to do so be adjustable so that they the predetermined amount of powdered solid distributed over a predetermined period of time in the feed connector 13 enters.
- the metering device 29 can be a volumetric pump Snail or a gravimetric conveying snail or a gravimetric have conveying belt conveyor. In the simplest and sufficient Execution is a volumetric conveying screw. Such metering devices are known and commercially available. Basically it is also sufficient if a setpoint is to be given for the unit of time Solid volume is adjustable.
- a level measuring device is arranged, which is a non-contact has working level probe 41.
- This probe 41 gives continuously fill level signals to an input 42 of a control device 43.
- These signals are processed in the control device 43 in such a way that a minimum level 44 and a maximum level 45 corresponding control signal is generated, which via outputs 46, 47 for alternative or cumulative control of the drive motor 11 the mixing shaft 9 and / or a pump drive motor 48 is supplied.
