- a dosing screw can be selected as the dosing device and its Loss of volume in the course of the activity and / or the reduction the building material mixture delivered by it and the tax or Computer unit or one of these associated memories can be entered.
- a dosing screw is a special one expedient and robust within a dosing channel Dosing device in which the increase in wear due to Decrease in the outer diameter is also easily determined and can be measured.
- a device for the continuous dressing of a dry or pourable building material mixture such as screed, concrete, mortar, plaster or the like with a mixing liquid, for example with Water, with a feed device for the building material mixture, one Dosing device and a downstream mixing chamber in particular a continuous mixer with a feed for the Mixing water and a control for the supply of the Mixing water can solve the above problem characterized in that in the supply line for the Mixing water provided an adjustable valve or shut-off device which is connected to the controller, which is an electronic Memory and / or a programmable computer unit for Save the - per unit of time or depending on throughput - each decreasing due to wear, the mixing chamber actually has supplied amount of the building material mixture, so that the amount of the mixing water supplied by the inlet and the inlet respective amount of the building material mixture controlled accordingly is feedable.
- this decrease curve for the throughput of the metering device contains, it can accordingly the delivery of the mixing liquid within the framework of specified standards or tolerances and automatically Carry out the entered program as follows. Because this makes each combined amounts of the building material mixture and the mixing liquid included in the computer or memory at different times they can also be used at any time to prove the quality of the made-up building material mixture can be called up. Thus the Water requirements for each product are limited within its tolerance range and it is avoided that concrete or screed or any other Building material is watered over or possibly made with too little water becomes. Rather, according to the respective consumption Dry material or building material mixture the required Mixing water programmed using the control or computer unit and be fed precisely.
- a control for the speed of the drive motor is provided and that this control an electronic Memory and / or a programmable computer unit for storing which - per unit of time or throughput-dependent - due to wear decreasing amount dosed by means of the dosing device of the building material mixture, so that the wear-related decrease the metered building material mixture by increasing the speed of the drive motor can be compensated.
- a control of a controllable Valves or shut-off devices and a control for the speed the drive motor is provided and an electronic memory and / or a programmable computer unit for storing the - per unit of time or depending on throughput - each due to wear decreasing supply of the building material mixture for a combined increase the speed of the drive motor and reducing the water supply is provided.
- the dry or free-flowing building material mixture by means of a volumetric dosage, preferably by means of a dosing screw into the mixing chamber continuously operating continuous mixer.
- a volumetric dosage preferably by means of a dosing screw into the mixing chamber continuously operating continuous mixer.
- the amount calculated and using that in the computer or memory stored water value or water binder dry material factor the correct amount of mixing liquid over a Control unit set. Wear and tear of the volumetric dosing or the dosing screw is used by this calculator takes into account so that the values are automatically dependent be corrected from this wear or tear.
- a device designated as a whole by 1 (FIG. 5) is used for Preparation of a pourable building material mixture such as screed, concrete, Mortar, plaster or the like with a mixing liquid in which Usually with water.
- the device 1 has a feed device 2, in Fig.1 and 5 by an inlet nozzle and the vertical Arrow Pfl is indicated.
- the still dry Building material mixture are filled into the device 1, be it using sacks, be it directly from one above Storage or silo containers.
- the device 1 also has a metering device 3 with a Dosing screw 4 in a metering tube 5 and one downstream of it Mixing chamber 6, in which a mixing shaft 7 with Mixing tools 8 is housed, the mixing shaft 7 in Continuation of the dosing screw 4 and a conveyor shaft 9 below the feed device 2 extends so that a single drive motor 10 for driving both the conveyor shaft 9 and this in Direction of conveyance following dosing screw 4 and the mixing shaft 7 with the mixing tools 8 is sufficient.
- a horizontally arranged continuous mixer is also provided a feed 11 (Fig.5) and an inlet 12 for the mixing water in the area of the mixing chamber 6.
- a valve or Shut-off device 13 which in a manner to be described with a Microcontroller or a control device or Control unit is preferably connected in the form of a computer, so that the amount of through the feed 11 and the inlet 12 of the Mixing added mixing water can be controlled or regulated can.
- a control or regulating unit 14 is shown in FIG an electronic memory and / or a programmable Computer unit for storing per time unit or depending on throughput each decreasing due to wear, actually supplied and metered amounts of the building material mixture is used the supply of the mixing liquid by means of the valve or Shut-off device 13 changed in the way the dosing screw 4 worn out more and more over time due to throughput or is worn out.
- Figures 2 to 4 show how the outer diameter the dosing screw 4 and the screw flights attached to it 4a from new condition to medium wear to Uselessness decreases.
- the degree of wear shown in Figure 4 results in practically no dosing promotion of sufficient quantity, so that the dosing screw 4 is then removed and replaced or for example by cladding back into one state must be moved, which corresponds approximately to the new condition.
- this can be repeated after transportation predetermined delivery rates and / or according to predetermined actuation or Running times with regard to their different wear conditions and those still provided in these wear conditions Flow rate are measured, after which the wear-related determined Decrease of the conveyed by the metering device 3 Throughput of the electronic control or computing unit 14 is entered. As already mentioned, this then regulates or controls the supply of the mixing liquid via the valve or Shut-off device 13, which can be opened more or less.
- the dosing screw 4 provided in the exemplary embodiment has the advantage that the wear is particularly easy over their Volume loss can be measured, with the volume loss due to wear proportional to the decrease in throughput is. This regularity can easily be determined by experiment and program into the control or computer unit 14.
- Fig.5 it is also indicated that it is also possible to wear-related decrease in the metered building material mixture to compensate for an increase in the speed of the drive motor 10, reducing the water supply or increasing the Motor speed optionally, but possibly also used in combination can be.
- the mixture of building materials becomes quantitative with a mixing liquid dosed and the amount of mixing liquid to be added to this dosed amount of the building material mixture matched.
- the Wear of one used for dosing the building material mixture Dosing device and thus the decrease in the supply of the building material mixture depending on the runtime and / or the throughput of these Dosing device 3 determines and the supply of the mixing liquid reduced in proportion to this wear and / or speed of the drive motor 10 of the metering device 3 proportional to this Wear increases so that the building material mix with a continuous working or continuous mixer turned on and still one correct ratio between the building material mixture and the Mixing liquid can be obtained.
