Definitions

  • the invention relates to a process and apparatus for the preparation of mortars.
  • FR-A-2 357 400 discloses a process for the preparation of mortar, using a mobile silo for aggregate and binder, which are contained in separate compartments within the silo, wherein the volumetric flows of aggregate and binder are mutually adjusted, whereupon the aggregate and the binder are mixed together with the addition of water.
  • said silo consists of a body with several separate compartments.
  • storage capacity extending bays are stored in the compartments, whose storage capacity they extend in the operational mode.
  • the compartments are empty (but for said bays), while the silo is in transport mode. Before use at the building site the bays must be inverted and the compartments filled.
  • the silo and operation platform/towing unit form an intricate and expensive system, that is inseparable.
  • the object of the present invention is to provide an improved process of the type described hereinbefore. To this end the process is designed in such a way that, while the silo is located in a storage yard or in a storage space for aggregate and binder, the containers of the silo are filled, the silo is then conveyed to the building site, where the volumetric flows of aggregate and binder are adjusted, whereupon aggregate and binder are mixed together with water, yielding the mortar ready for use at the building site.
  • a further object of the present invention is to provide an apparatus for the preparation of mortar according to the process mentioned above, comprising a silo, which is provided at the bottom with a funnel shaped section and which has been mounted on an undercarriage, such that the silo can stand upright, wherein the silo has at least one partition for the separate storage of aggregate and binder in individual compartments, each compartment having one outlet, the outlets leading to a mixer in a mixing chamber, as is known from FR-A-2 357 400.
  • the outlet for the aggregate is provided with a conveyor screw, the axle of which also forms the axle of the mixer in the mixing chamber, whilst the outlet of the binder compartment is provided with another conveyor screw, in such a way that the two conveyor screws discharge into the mixing chamber and that the speeds of the conveyor screws for the binder and for the aggregate are adjustable relative to one another.
  • the mixing chamber may be provided with a metering valve for water discharging into it.
  • the outlet for the aggregate may be provided with a mechanically operated slide, safeguarded against freezing fast by heating, with a further heating element mounted high up in the silo compartment for the aggregate, so that in the event of slight night frost jamming of the slide and clogging together of the aggregate can quickly be undone through heating.
  • the shaft of the conveyor screw for the binder has been provided with a cam against which a plunger rod rests; this rod terminates in the binder compartment and carries transverse projections.
  • US ⁇ A ⁇ 4 298 288 describes an apparatus for the preparation of special mortars for swimming pools, that consists mainly out of drive and mixing units, and has a limited load capacity. The possibility of refilling at the building site is explicitly indicated.
  • the apparatus constitutes a complete mortel factory, located on a trailer for mobility.
  • the apparatus according to the invention can be loaded and transported on and unloaded from a truck. It is filled in a storage yard and can be used completely independent of its means of transport.
  • the drive and mixing units form a minor part, as the storage spaces forms the major part of the apparatus. It is especially intended for refilling only at the storage yard.
  • the apparatus comprises a silo 1 with a funnel-shaped section 2 which is provided with an undercarriage 3.
  • the silo is divided by means of a partition 4 into the compartments 5 and 6.
  • Compartment 5 has a filling hole 7 for the aggregate and compartment 6 a filling hole 8 for the binder.
  • a conveyor screw 9 with a mixing chamber 10, the said conveyor screw 9 being driven by an electric motor 11 at a constant speed of rotation.
  • a second screw 12 is mounted which communicates through a transfer line 13 with the mixing chamber 10.
  • the conveyor screw 12 is driven by an electric motor 14 with an infinitely variable speed regulator.
  • the mixing chamber 10 is provided with a branch 15 which has a metering valve for the supply of water.
  • Mortar of the desired composition is prepared in the following way. From compartment 5, aggregate passes onto the conveyor screw 9 which transports the aggregate at a constant speed to the mixing chamber 10. At the same time, the binder is led from compartment 6 to the second conveyor screw 12 which transports the binder also the the mixing chamber 10 through line 13.
  • the conveying speed of the conveyor screw 12 can be selected at will with the aid of the infinitely variable speed regulator of the electric motor 14.
  • the magnitude of the adjusted speed at which the second conveyor screw 12 is driven should be determined experimentally in such a fashion that the desired mixing ratio of aggregate to binder for the jointing or concrete mortar is obtained.
  • Mortar can be prepared in the way outlined above by a continuous process. Dosing of the aggregate and the binder can be effected without valves. In consequence, the two conveyor screws 9 and 12 fulfil the dual function of dosing and conveying.
  • the outlet at the bottom of the aggregate compartment can be closed with a slide 20 in order to permit the mixing chamber to be emptied. After slide 20 has been closed and the supply of binder stopped, the mixing chamber 10 is emptied and flushed clean with water.
  • an electric heating cable has been mounted near the supporting edge of the slide.
  • a heating element 21 is provided high up in the aggregate compartment so as to eliminate or prevent any clogging together of the aggregate.
