Definitions
- the present invention relates to a method and an arrangement for automatic mixing of water and concrete for rock bolting.
- the present invention which is defined in the following patent claims, has the purpose to achieve an automatic method and arrangement for mixing of water and concrete that guarantees an accurate mixing proportion between water and concrete without negative influence from air admixture.
- the arrangement disclosed in the figure includes a mixing vessel 1 in which a mixing arrangement in the form of a mixer 13 is arranged.
- the mixer is run by a motor 15, which running is controlled by a control unit 3.
- a control unit 3 For determination of the amount of material in the mixing vessel 1, this is arranged for weighing with a scale 4.
- Water is added to the mixing vessel 1 from a water source 16 via a valve 11 and a pipe 17.
- Concrete is added to the mixing vessel 1 from a supply 18 via a feeder 12 and a pipe 19.
- the valve 11 and the feeder 12 are controlled by the control unit 3.
- the arrangement shown on the figure works in the following way. First the operator sets the demanded weight ratio between concrete and water and the demanded total weight for the mixture unless the whole volume of the mixing vessel is demanded. These values are stored in the control unit 3.
- the control unit 3 calculates the demanded weights of concrete and water from either the demanded weight of the completed mixture or from the volume of the mixing vessel 1.
- the mixing starts by weighing the amounts of water and concrete with the scale 4.
- the mixing vessel is standing on the scale 4.
- the mixing vessel may of course be hung up, e.g. in a load cell.
- the water is added quickly from the source 16 to about the wished amount.
- the amount of concrete is recalculated to take into account the real amount of water.
- the concrete is added to the mixing vessel 1 with the feeder 12, e.g. a screw feeder.
- the motor 15 is started to run the mixer 13 a predetermined time set in the control unit 3.
- the mixture of water and concrete is transferred to the drill hole 2 with the pump 14.
- the mixing vessel 1 and other equipment should be cleaned to prevent that the equipment is destroyed at an interruption of the work. This is made by adding water to the mixing vessel 1 until the water level 5 reaches an upper, selectable limit.
- the mixer 13 and the pump 14 are run during the whole cleaning procedure.
- the water level 5 is determined with the help of the scale 4.
- the mixing vessel is refilled to the upper level. This method is repeated a predetermined number of times or during a predetermined time.
- the cleaning is carried through the equipment is switched off and the mixing vessel 1 is emptied.
- the whole process is controlled by the control unit 3.
