Definitions

  • This invention deals with a mobile device for producing a concrete mixture.
  • the term concrete mixture for the purposes of this invention should be understood as any mixture produced by mixing filler with a binding agent, which besides the concrete mixtures includes also anhydrite mixtures, foam concretes, cement mixtures and the likewise products.
  • the binding agent is advantageously especially a cement and anhydrite, but also other materials, which when mixed with filler in a mixing device, lead to forming a mixture capable of hardening, just likes the concrete and the like.
  • the term filler according to this invention means mainly a sand and / or a gravel aggregate.
  • a screw feeder or other device directly from reservoir located on the lifted technology, with which the reservoir is firmly connected.
  • the mixing device is located in the back of a truck or semi-trailer and is thus arranged during lifting of the relevant part of the mobile mixing device together with the reservoirs undermost.
  • a disadvantage of this arrangement is that the amount of filler is substantially limited by a capacity of the reservoir of the filler, because filling of the heavy filler into lifted reservoir during the operation of the mobile mixing device in terms of safety is practically excluded.
  • This system essentially prevents effective production of anhydrite or concrete mixture in an amount greater than what can fit into reservoirs, which currently have the mentioned volume of 15 cubic meters.
  • Another disadvantage of this device is a possibility of its use only in places where is possible to ensure the required lifting up of the technology and where there is no risk of tipping over the entire semi-trailer, like for example at a slope underlay.
  • Another type of a mobile mixing device is such that the reservoir with material will not be lifted up and the material into a mixing device is dosed via a long feeder running below the entire reservoir.
  • An example of this solution is a European patent application EP 2636499 A1 of 06/03/2013 , which describes a mixing unit arranged on the chassis of a lorry, comprising one filler reservoirand one reservoir for cement.
  • the reservoir of the filler and along its entire length is an outlet opening and consists of two parts, leaning to each other, thereby ensuring its continuous emptying.
  • Under the filler reservoir is running a long feeder.
  • the binding agent reservoir is arranged behind the filler reservoirand above a section of the technology of mixing equipment, which is disposed in the rear of the vehicle.
  • the amount of produced concrete mixture also in this case is limited by the capacity of reservoirs, so without using a special technique for supplementing the filler and/ or the binding agent, again is possible to produce at most about 15 m3 of the mixture.
  • the maximum volume of filler on the lorry or semi-trailer is generally limited by the maximum permissible weight of the vehicle or semi-trailer, possibly by permitted loads on the axle.
  • Due to the placement of filler reservoir is the procedure of refilling of filler substantially similar to that described for the first type and requires special technology.
  • the only difference is that the addition of filler can take place in the working position. But it is virtually impossible to ensure filling of the filler into the respective reservoir without the use of additional devices that enable the refilling.
  • not-lifted reservoir is the higher stability of the machine in working position, when the centre of gravity is positioned lower than in case of the lifted technology.
  • Other similar mobile mixing devices are described in documents US 2007/0189109 or FR2982190 , which also contain consecutively arranged reservoirs for filler and binding agent, in case of FR2982190 even further possible reservoirs, with all the described disadvantages.
  • a mobile mixing device whose essence and advantageous features are described in the attached demands.
  • the production of concrete mixture in a mobile device for the production of concrete mixture according to this invention is preceded as follows: Before the arrival of mobile mixing device for the production of concrete mixture to the construction site is filled the binding agent reservoir, either from a silo with binding agent or from a cistern. Then is filled the reservoir of filler, advantageously by means of a loader, which is faster, or using the filling device, which is part of the technology.
  • the mobile device for producing concrete mixture Upon arrival at the building site the mobile device for producing concrete mixture is unfolded into the working position so that the reservoir of finished mixture is lowered, for example hydraulically, until the mixing device is positioned on strain gauge transducers, thereby allowing to detect the weight of individual components of the concrete mix, if their precise quantity is required, given for example by the type of concrete and the like. It is obvious that the dosage of individual components of the concrete mix may be performed by any suitable method commonly used in the preparation of concrete mixes, so the presence of the strain gauge transducers and positioning on them before start of preparing the concrete mix is not absolutely necessary and is herein mentioned only as an advantageous solution.
  • the receiving reservoir of automatic filling gravel aggregate is unfolded, where according to another preferred embodiment of this invention the appropriate part of the receiving reservoir, including the filling screw feeder is lowered onto the ground, for example, again by using hydraulics, and individual walls of reservoir are unfolded, for example mechanically, so that a lorry with gravel aggregate can drive rearward, up to the reservoir and unload the gravel aggregate into receiving reservoir .
  • the gravel aggregate will be transferred into the filler reservoir.
  • the oblique screw feeders are fed by two horizontal worm feeders.
  • the amount of the individual components is specified in the recipe for desired concrete mix, which is advantageous and common in this technical field.
  • the order of dosing the individual components is optional and is preferably given by the recipe and the corresponding technological process for producing of the given mix.
  • the ingredients in this case are weighted in the mixing device, which is weighted.
  • the control system first triggers the mixing device, then the screw feeder doses the binding agent into mixing device, until the entire required amount has been dosed. Afterwards or simultaneously (if permitted by technology), is dosed water - for example via a flow-meter. Finally, using a belt feeder or feeder of filler, the filler- mostly the gravel aggregate - is dosed into the mixing device.
  • the concrete mixture is mixed up and then discharged to the reservoir of finished mixture, where it is mixed up using a stirrer.
  • the finished concrete mixture conveyed from the reservoir for finished mixture to the destination advantageously is continuously pumped with a pump and to the place of storage is transported by a hose, connected to this pump or is transported to the place of storage by using other devices.
  • the hose can be 150 m long.
  • Mobile device for the preparation of the concrete mixture in this embodiment is arranged on the chassis of a semi-trailer of a lorry. According to other embodiments, not illustrated herein, the mobile device can be arranged on the chassis of another suitable transport vehicle.
