Definitions

  • the invention relates to a monitoring device for a mixing and conveying system that can be connected to a building material silo and the silo content together with if necessary several building materials or additives with water or the like mixes ready for use and e.g. via a concrete pump or forwards a screw conveyor.
  • a concrete pump or forwards a screw conveyor On construction sites over building material silos are distributed over a wide territorial area, e.g. Cement silos used. It is mostly about cylindrical containers placed in a conical drain funnel pass over and on a frame with vertical Axis are arranged. There is a separate one at the drain funnel Unit, namely a mixing and conveyor system connected.
  • the building material from the silo is put together if necessary with other building materials or additives e.g. to Mortar or concrete or the like in a predetermined ratio mixed with water ready for use.
  • the invention aims to provide a monitoring device of the type described above to create the capture of the consumption of the building material, the fill levels of the silos, one Quality control and timely maintenance of the silo and especially the mixing and conveying system.
  • This is achieved by having a measuring device for the incoming Amount of water in the water inlet of the mixer and / or for the opening time of an inlet valve with a known flow rate per unit of time or for the operating time one Screw conveyor or pump is provided that the measuring device is connected to a data storage device and a computer and the calculator calculates the quantity of the ready-to-use building material mixture determined and possibly over the timeline stores that from the used building material mixture at known Filling quantity of the silo in the computer the remaining filling quantity can be determined is and that a connection for a display device with Data storage for transmission and display of measurement and or or consumption values and or or a transmitter for transmission the measurement values of the measuring device, if necessary, on demand to a central unit and to record the operating and Refill data of the mixing and conveying system and
  • Mixing ratios can be from the amount of feed per unit time Water or with a known flow rate per Time unit from the opening time of a water valve or Mixing valve determines the total amount consumed in the computer become. This passes through the conveyor, e.g. Auger or feed pump for processing on site. The amount of building material used, over the mixing ratio broken down into individual quantities of the components is wrongly proportional to the level of the or the building material silos.
  • the saved measured values can via a plug connection to a connectable display and Evaluation device are transmitted, which contains the computer and from the amount of water or feed time and from the mixing ratio of the components the consumption and the remaining filling quantity of the silo determined.
  • the computer can use the Data storage also directly in the mixing and conveying system be installed.
  • the transfer of data from the measuring device or the results from the calculator can be conducted, however preferably via a wireless radio connection to a Headquarters sent continuously or intermittently or by this can be called up at time intervals.
  • the headquarters recognizes the fill level of the building material silos and directs the refill and provides information about the consumption of the concrete (Building material) depending on the timeline.
  • a temperature sensor for simultaneous detection and display or storage of the ambient temperature or of Operating temperatures or conditions at different Measuring points above the time axis is provided.
  • the ambient temperature allows conclusions about the quality of the manufactured building material mixture and that in the mixer or the Conveyor measured temperature, e.g. on the drive, allow defects in the machine part to be identified at an early stage.
  • other parameters such as operating pressures can also be used or speed of the screw conveyor or electrical Values of the drive (e.g. current consumption) can be transmitted remotely.
  • the invention enables simple and yet efficient monitoring of the most important criteria immediately on the construction site and / or for the machine operator or distributors also by remote inquiry or telemetry.
  • FIG. 1 shows a building material silo with mixing and conveying system and with a monitoring device and Fig. 2 a center along with a typical result of monitoring in diagram form.
  • a building material silo 1, e.g. for cement, is a mixing and Conveyor system 2 downstream.
  • a water meter 8 can also be provided.
  • control valve 5 and the solenoid valve 7 each the passage cross section of the mixing ratio customized.
  • the solenoid valve 7 can remain unchanged Cross-section can be operated intermittently so that a given amount of building material the exact amount of water is added.
  • the over the water meter 8 or based on the Opening time of the solenoid valve 7 determined amount of water per unit of time is about the mixing ratio (e.g. water: cement) proportional to the consumption of the ready-to-use Building material mix (concrete, mortar ).
  • You can use additional sockets 9 other building materials or aggregates in the Mixture should be included and the mixing ratio in do the calculation. This is shown in FIG. 1 in one Computer 10 performed, which also has a data memory disposes.
  • the results of the consumption quantities over the timeline and the remaining fill levels of the silo (s) 1 can by a display or evaluation device 11, which if necessary can be connected to a plug connection 12 become.
  • the measurement data can be stored in the mixing and Conveyor system 2 and the computer 10 also in the display and evaluation device 11 may be provided.
  • the mixing and conveying system 2 still via a transmitter 13, which contains the data on the building material quantities per time unit in transponder mode to one Central 14 (Fig. 2) transmitted. It can be this data (Measurement data or already calculated consumption or level data) also from the control center 14 at the transmitter 13 at time intervals be queried.
  • control center 14 (or in the display or evaluation device 11) then lies, for example, the diagram shown in FIG. 2 in front. It is with full lines of consumption V in tons the time axis plotted that the time t starting from 0 o'clock with intervals of 3 hours. You recognize that the plant went into operation at 6 am and Breaks from 8 a.m. to 9:30 a.m. and from 12:30 p.m. to 1:30 p.m. were observed. That day was working with this System finished at 4:30 p.m. The commissioning took place the next day already around 5 am and it was - with breaks - worked until 7.30 p.m. The consumption is the silo level wrong proportional. Line 15 marks the minimum fill level of the building material silo.
  • step line of consumption V reaches line 15 over the time axis t, then the silo 1 must be refilled.
  • the diagram shows for the amount of building material spent (processed) at any time. In This diagram also shows the outside temperature T (° C) indicated. This is via a temperature sensor 16 on the Construction site recorded and transmitted together with the other data. Other operating states of system 2 can also be measured electronically logged and transmitted.
