Definitions

  • the invention relates to a concrete plant for the production of fresh concrete according to the preamble of claim 1.
  • Fresh concrete is mainly used in large quantities at large construction sites and is delivered to the corresponding construction sites by truck with a concrete mixing attachment from fresh concrete plants. In the fresh concrete plants, the concrete must be made available in the desired quality and in sufficient quantity.
  • Concrete plants of this type include silos for the individual concrete components, ie: cement, sand, gravel or the like, the components mentioned additionally being present in different properties, for example with regard to their grain size.
  • the starting materials are usually dosed with a weighing device finally to be mixed in a mixing device to the desired fresh concrete. Then, as is known, the concrete is filled into concrete transporters and used.
  • the object of the invention is therefore to propose an arrangement for the various devices necessary for the production of fresh concrete, which entails lower investment costs when building the concrete plant and which enables the short transport routes of the concrete components during the production of the concrete.
  • simple and energy-saving cold protection for moist bulk goods such as sand or gravel should be made possible.
  • silo chambers for different components of the later fresh concrete are built within a common silo housing.
  • the silo chambers For a compact design, it is advisable to arrange the silo chambers around a common center with adjoining or paired common partitions. As a result, the full cross section of the silo housing is used to store the concrete components.
  • the silo chambers are arranged in the form of a polygon with the same side lengths or a circle, the partitions of the individual chambers extending from the circumference of the polygon or the circle to the center.
  • the underside can be formed more easily in the form of a horizontal bottom, whereby so-called trigger slide valves for dosing the bulk material are to be provided.
  • the insulation layer of the silo housing can be completed by a pipe system in the outer wall of the housing. It is important to note that fresh cement contains a not inconsiderable amount of residual heat when it is delivered. With a pipe system in which a heat-conducting medium circulates, this residual heat can be distributed to all silo chambers of the concrete plant. The advantages of using this residual heat for tempering the moist bulk goods are obvious and do not require any further explanation.
  • the weighing device for dosing the individual fresh concrete components can be attached directly below the silo chambers.
  • the bulk goods trickle into gravity by themselves into the weighing device.
  • the concrete plant has a symmetrical elongated, possibly even cylindrical shape.
  • the cross section of the entire structure remains the same from top to bottom. Due to this uniform and compact design, a steel structure is recommended for the realization of the concrete plant.
  • a steel structure that runs straight through from the floor to the top edge with a comparatively simple housing is an extremely cost-effective alternative when building such a system.
  • a load elevator which is arranged on the side of the housing, is recommended for filling the high silo chambers.
  • the bulk materials that he conveys to the top level of the concrete plant can then be conveyed on a conveyor belt under the roof of the housing in the middle.
  • a distributor arm which can be pivoted about the individual silo chambers with an axis of rotation located in the middle of the housing, is supplied by the conveyor belt with the bulk material conveyed upwards by the load elevator.
  • the distributor arm has its own conveyor system, for example a conveyor belt, and is therefore able to fill the various silo chambers depending on its rotational position.
  • the multi-chamber system described also proves to be of great advantage when filling the silo chambers, since the same conveyor system is used for each chamber.
  • FIG. 1 shows a concrete plant 1 with a filling room 2, a silo room 3, a weighing room 4 and a mixer room 5.
  • a load elevator 6 with an ejection nozzle 7, under which the receiving end 8 of a conveyor belt 9 is located.
  • the conveyor belt 9 ends above a conveyor hopper 10.
  • a distributor arm 11 is arranged to be pivotable about an axis of rotation 12.
  • Its ejection opening 13 is located above silo chambers 14 which have cross members 15.
  • filling hoppers 17 On the underside of the silo chambers 14 there are filling hoppers 17 with additional scales 18.
  • a hopper 19 which opens into a mixer 20 is provided below the mixer 20.
  • a filling device 21 below which a schematically represented concrete transporter 22 is located in the entrance 23.
  • the entrance 23 is on the bottom floor 24 of the concrete plant.
  • FIG. 2 Filling room 2 and silo room 3 are shown enlarged together with the components contained therein in FIG. 2, as are the weighing room 4, the mixer room 5 and the bottom floor 24 in FIG. 3.
  • the execution of the building in the form of a steel structure can be recognized by means of various struts 25, which are indicated in the area of the bottom floor 24.
  • the outer skin 26 of the building is double-walled.
  • the starting components are first introduced into the respective silo chambers 14 provided for this purpose via the load elevator 6, the conveyor belt 9 and the distributor arm 11.
  • the introduction of the bulk goods is of course not always necessary, since the silo chambers 14 have a large holding capacity.
  • the individual concrete components are metered via the filling hopper 17 and the addition scales 18 according to the desired concrete quality and added to the mixer 20 by means of the filling hopper 19.
  • the fresh concrete After the fresh concrete has been mixed, it is filled into a concrete transporter 22 for transport to the respective destination.
  • the entire arrangement manages with minimal funding routes, since the individual processing points are close together.
  • no additional driven conveying devices are required, since gravity can be used for the transport of goods during the production process.
  • the thick double-walled outer skin 26 ensures good temperature insulation.
  • the residual heat of the cement in some of the silo chambers 14 can be used to warm up moist bulk goods in other silo chambers.
  • such a simple construction of an inexpensive steel construction which is continuous from bottom to top, as indicated by the struts 25 in the bottom floor 24, is accessible.
  • FIG. 4 shows a cross section through the filling chamber 2.
  • it has the shape of an equilateral nine-corner.
  • Partitions 27, which extend from the corner points 28 to the center point 29, divide the cross section into nine sub-segments, which form the silo chambers 14.
  • Four of these segments 14 are covered by floor covering sheets 30, which can be placed if necessary, so that the entire filling space 2 is accessible via the floor covering surface 30.
  • a grating 31 which serves as a catwalk when the flooring sheets 30 are removed.
  • Each of the silo chambers 14 can be visually inspected via this grating 31.
  • the grating 31 can be reached via the centrally located staircase 16.
  • FIG. 6 shows a cross section through the bottom floor 24 of the concrete plant with the entrance 23 for a concrete transporter 22 not shown in this figure can be clearly seen that the floor plan in the bottom floor 24 allows space for a laboratory room 36, a boiler room 37 and a tank room 38. Of course, the rooms mentioned can also be used for other purposes.
  • An ascent 39 is shown laterally in FIG. 6, which leads to the mixer room 5, which is located above the bottom floor 24 and is therefore not shown in FIG. 6.
  • FIG. 7 shows an external view of a concrete plant according to the invention, the simple and compact construction in particular being clear.
  • the front of the concrete plant is essentially filled by the outer skin 26.
  • Several windows 40 are installed at the level of the bottom floor 24, the mixer room 5 and the weighing room 4.
  • the lower end 41 of the concrete filling device can be seen in the entrance 23.
  • 7 also shows the load elevator 6 with its ejection nozzle 7 and the receiving end 8 of the conveyor belt 9.
  • the steel structure of the building is indicated in the lower area by dash-dotted lines 42 instead of struts 25 in Fig. 1.
  • the advantages of a steel construction, particularly with such a uniform and symmetrical design, are the significantly lower investment costs compared to other designs.
  • the outer circumference of the filling room 2 is set back somewhat from the rest of the building, so that a tour 43 results above the silo room 3.
  • the building roof 44 is supported on the main structure of the building via support struts 45.
  • the illustration also clearly shows that the ascent 39 leads to a door 46 of the mixer room 5.
