Definitions

  • the invention is directed to a mixing and metering device for masonry mortar, screed or the like. with two separate inlet openings for the mortar components, such as sand and cement, a mixing device arranged downstream of the inlet openings and an outlet opening on the discharge side.
  • Devices of this type are required in order to discharge and mix them in a metered manner on the construction site from storage silos which are known per se and in which the individual mortar components are stored separately.
  • the invention is based on the object of designing a device of the type mentioned at the outset in such a way that it can be produced inexpensively on account of a simple and robust construction and at the same time has a high level of operational reliability with little maintenance.
  • conveying and loosening elements which are in rotary connection are arranged in each conveying channel coaxially with the metering screws and with them. These elements ensure that the components entering through the inlet openings are loosened and any lumps present in them are crushed, so that there is a continuous flow of material without the risk of blockage or the metering accuracy of the downstream metering screws, which adversely affects delivery discontinuity.
  • a single drive motor drives a continuous shaft in each fan and metering channel via individual gear sections.
  • the mixing elements can also be arranged in the mixing space on this continuous shaft.
  • the dosing ratio for the individual components, e.g. Sand and cement is specified by adjusting the gear ratio of the gear sections to one another.
  • a gearbox with a variable transmission ratio can be used here, or a transmission can be permanently set to meet the most common requirements.
  • Flange devices for attachment to a storage silo for the components with at least one essentially vertical partition wall and separate discharge openings for the individual components are also advantageously provided.
  • the flange devices are designed so that the outlet openings of the storage silo are aligned with the inlet openings or are brought into connection via shaft sections.
  • a storage silo 1 In the drawing, the lower part of a storage silo 1 is shown. This has a vertical partition 2 which divides the storage silo 1 into two sub-containers 3, 4, one of which is intended for sand and the other, smaller for cement.
  • each partial container 3, 4 there is an outlet opening 5, 6, to each of which a shaft part 7, 8 connects.
  • These shaft parts 7, 8 are connected via a flange 9, shown only schematically, to the device 10 according to the invention, which has corresponding separate shafts 11, 12 following the flange 9, on the upper side of which separate inlet openings are provided for the two components.
  • the device 10 has two conveying and metering channels 13, 14 which run parallel to one another and which are located directly below the outlet openings of the shaft parts 11, 12 and are each separated from them.
  • a rotating shaft 15, 16 runs in the conveying and metering channels 13, 14, which are mounted on the front housing end wall 17 seen in the discharge direction on an intermediate wall 18 and on the rear housing end wall 19 seen in the discharge direction and driven by a motor 20.
  • Gear sections 21, 22 for each of the shafts 15, 16 are arranged downstream of the motor 20, the transmission ratio of the gear sections 21, 22 specifying the relative rotational speed of the shafts 15, 16 and thus the delivery rate of metering screws 24, 25 arranged in a metering section 23.
  • loosening elements 26 are arranged below the shaft sections 11, 12 forming the inlet openings on the shafts 15, 16 together with conveying elements not shown in the drawing. Lumps of material are broken up by the loosening elements 26, so that continuous conveying through the conveying elements can take place from this loosening area 27 into the metering area 23.
  • a mixing chamber 28 is provided between the intermediate wall 18 and the end wall 19, the length of which defines the mixing region 29.
  • a water supply line 30 with an upstream flow regulator 31 opens into this mixing chamber 28, which is only indicated schematically in the drawing.
  • the mixing is accomplished by means of mixing elements 34 seated on the shafts 15, 16.
