Definitions

  • the present invention relates to a plant for production of a construction material.
  • the present invention finds widespread use in construction, for the production of a generic construction material, particularly concrete.
  • Plants for the production of construction material such as for example concrete, to which reference will be made herein below, without any loss of generality, require extensive spatial areas, given the considerable amount of space required by the various structural elements.
  • silos and containment hoppers are necessary for storing each inert material (sand, gravel, and water) or the various additives required for the production of concrete.
  • a screw pipe departs from the bottom of each silo and conveys a determined amount of the inert material contained therein toward a mixing tower located at a certain distance and at a certain height.
  • the containment hoppers instead release determined amounts of the stored material onto a conveyor belt, which then pours it all inside the mixing tower.
  • the mixing tower is generally a very large unit, in a fixed position interposed between the silos and the containment tanks, inside of which a body capable of mixing the material poured into the tower is moving.
  • Stationary plants generally supply construction material to work-sites located in the vicinity or to those work-sites that do not require excessive amounts of concrete.
  • connections between the storage silos and the mixing tower or between the mixing tower and the containment hoppers involve a large number of moving members with resulting higher production costs for maintenance and repairs, in addition to reduced levels of safety at the work-site.
  • the technical task on which the present invention is based is to propose a plant for production of a construction material, said plant being able to overcome the drawbacks of the prior art cited hereinabove.
  • An aim of the present invention is to propose a new plant for production of a construction material, capable of producing concrete of certified quality in amounts sufficient to satisfy any operative need of a work-site, without the need to have recourse to external suppliers when a large quantity of construction material is required so as to have continuous jets.
  • a further aim of the present invention is to realise a plant for production of a construction material, said plant requiring reduced space and being compact and simple in structure, so as to avoid excessive moving parts, increase safety on the job and reduce the costs of maintenance and repairs. Furthermore, the present invention proposes to realise a plant for production of a construction material, making it possible to increase hourly production and the capacity for storage of the inert materials, while concomitantly decreasing the demand for electrical power.
  • the present invention proposes to realise a plant for production of a construction material, producing an excellent construction material, complying with the proper doses and the correct mixing sequences.
  • the plant which is the subject matter of the present invention, can be utilised as a mobile plant, and is thus assemblable, when required, at a work-site, and as a stationary production plant, realised in suitable dimensions.
  • the plant 1 which is the subject matter of the present invention, is designed for the production of any construction material, preferably concrete.
  • FIG. 1 A first example of the plant 1 that is the subject matter of the present invention is shown in Figure 1 .
  • the plant comprises at least two hoppers 2, each containing a respective component element 3 of the construction material.
  • the elements forming the concrete are sand and gravel, differing in particle size, water and additives.
  • the plant comprises more than one hopper 2, each containing a respective solid component 3, and at least one tank 4 for containing and batching a respective liquid component, such as water and/or various additives.
  • a respective liquid component such as water and/or various additives.
  • the hoppers 2 are arranged close together, preferably in an aligned position.
  • any other compact conformation is possible, such as, for example, an arrangement in a circle or, depending on the number of hoppers, arranged at the vertexes of a polygon, possibly as close to each other as possible.
  • the tank 4 is also arranged next to at least one hopper 2, so as to maintain a compact arrangement of the structure.
  • the plant 1 further comprises a mixing tank 5, inside of which the various component elements 3 are mixed together so as to form the concrete.
  • a specific mixing member 25 (unillustrated) that stirs and blends the individual component elements inserted in the mixing tank 5.
  • the mixing tank 5 has an upper loading opening 5' and a lower unloading base 5".
  • the lower unloading base 5" is generally closed and opens only at the end of a cycle of mixing, loading and working, that is, when the construction material is ready for use and the mixing tank 5 needs to be emptied, in a manner that will be explained below.
  • the mixing tank 5 is located immediately below the hoppers 2 and it is movable from one hopper 2 to the other so as to receive from each of them a determined amount of the relative component element 3 stored therein.
  • the mixing tank 5 is movable along a slide guide 8, which is set in motion by a specific moving means 9, such as, for example, an electric motor or a rack system, and it can move on tracks or on tyres.
  • the movement of the mixing tank 5 is translatory and defines a pathway 6 that is preferably a rectilinear, outward and return pathway.
  • the pathway may also be circular or polygonal.
  • the mixing tank 5 follows the pathway 6 outward and back, that is, taking on the same positions at least twice in each loading and working cycle.
  • the mixing tank may follow the pathway just once, along the entire loop.
  • the mixing tank 5 preferably, begins and ends the pathway 6 at a sole position 7.
  • mixing tank 5 advances along the pathway 6, it completes an entire cycle of loading and working of the component elements 3 and performs the mixing necessary to obtain the final product, that is, the concrete.
  • Each hopper 2 comprises a loading mouth 10, located superiorly, and at least one unloading mouth located inferiorly.
  • a first 11 and a second 12 unloading mouth both located in the lower part of the hopper 2, and aligned in sequence along the pathway 6 of the mixing tank 5.
  • the batching opening of the first 11 and the second 12 unloading mouths of each hopper 2 is positioned perpendicularly with respect to the path followed by the mixing tank 5.
  • the two unloading mouths 11 and 12 differ in dimensions, in such a manner that different quantities of the same inert component 3 can be batched.
  • the larger unloading mouth which is identifiable for example as the first mouth 11, is dedicated to delivery of large quantities of the inert component element 3, and thus for fast filling of the mixing tank 5.
  • the smaller unloading mouth which is instead identifiable for example as the second mouth 12, is dedicated to delivery of small quantities of the inert component element 3, and thus for precision batching and control of the correct quantity supplied and the desired weight of the material.
  • Suitable weighing and batching means 13 contributes to the correct determination of the quantity of each component element 3 weighed and poured into the mixing tank 5.
  • Said means is preferably located at the loading opening 5' of the mixing tank 5 or, alternatively, at each one of the unloading mouths 11 and 12 of each hopper 2.
  • the weighing and batching means 13 comprises loading cells for weighing and batching a preset quantity of a component element 3.
  • the component elements 3 forming the concrete are introduced into the mixing tank following the best sequence of introduction, so as to obtain a correct mix of the ingredients.
  • the mixing process is also facilitated by the movement of the tank 5.
  • the tank 5 undergoes stages of braking and acceleration, and the longitudinal inertial force created during these stages is a further improvement of the mixing process, above all during the return run.
  • the plant comprises transfer means 14 for transferring the construction material from the mixing tank 5 to a generic transport device 17, such as to a concrete mixer (illustrated in Figure 1 ) or to a conveyor belt, or even to special conduits that directly bring the concrete directly to where it is needed.
  • a generic transport device 17 such as to a concrete mixer (illustrated in Figure 1 ) or to a conveyor belt, or even to special conduits that directly bring the concrete directly to where it is needed.
  • Such transfer means 14 comprises a container 15, mobile between a loading position and an unloading position, and a lift 16 for moving the container 15.
  • the loading position of the container 15 is situated below the mixing tank 5, whereas the unloading position of the container 15 is located above the transport device 17.
  • the funnel-shaped container 15 pouring the content inside the concrete mixer.
  • the mixing tank 5 When the mixing tank 5 has completed the cycle of loading and working, it returns to the initial position 7, where it stops so as to permit the emptying thereof and the concurrent filling of the container 15.
  • the unloading base 5" of the mixing tank 5 opens, for example with a guillotine opening, and all the construction material produced in that cycle is poured into the container 15.
  • the container 15 is set in motion by the lift 16 and brought into the unloading position, above the transport device 17.
  • the movement carried out by the container 15 is indicated by the dashed line.
  • the container 15 translates toward the outside of the plant, drawing itself out from under the mixing tank 5, and it is then raised along the lift 16, to a height, in an external position with respect to the plant, so as to enable it to near the concrete mixer by running backwards, the latter being waiting to be filled.
  • the hoppers 2 are filled by means of a scraper 18, which climbs an embankment 19 up to the height of the loading mouth 10 of the hopper 2, to pour the load directly into the hopper 2.
  • the plant 1 comprises an automatic system for filling 20 the hoppers 2.
  • This filling system 20 comprises a bridge structure 21 overlying the hoppers 2, and at least one loading bucket 22 is mobile along the bridge structure 21.
  • the bucket 22 travels along the bridge structure 21 from a lowered position 22' at ground level, in which it is filled with a determined quantity of a component element, for example by means of a scraper 18, to a raised position 22", located above the hoppers 2, into which the loading bucket 22 pours its content into the relative hopper 2.
  • the bridge structure 21 comprises a hoist 23, which moves the loading bucket 22.
  • a lever and fulcrum mechanism 24 cooperates with the hoist 23 so as to realise the unloading of the material transported by the loading bucket 22 internally of the relative hopper 2, as illustrated in Figure 1 .
  • the plant described can be easily disassembled and transported to a work-site. An example of how the plant described is easily transportable is shown in Figure 4 .
  • the lower part of the plant 1, particularly the unloading mouths 11 and 12 of the hoppers 2, the tank 4, the transfer means 14 and the mixing tank 5 rest on a base 25, which is nothing other than a truck trailer 26.
  • the plant described can, however, also be installed as a stationary installation.
  • the invention thus achieves its set aims.
  • the plant described proves to be simple and compact in structure and has limited dimensions.
  • the moving parts are limited in number and are all confined to areas with limited access to workers, thereby increasing safety levels at the work-site.
  • This plant makes it possible to produce a considerable amount of construction material directly at the work-site, and above all, with a continuous flow, avoiding interruptions or supplies from eternal suppliers resulting in increases in production costs.
  • the mixing tank is of limited dimensions and thus has a limited capacity, but, at the same time, it requires less power and is more agile, with lower consumption levels, as it is able to optimize the loading and working cycles and to operate non-stop.
  • the mixing of the elements proves to be better, more effective, owing also to the movement of the mixing tank itself.
  • the weighing and batching system makes it possible to achieve high precision in the proportions of the inert elements introduced and thus produce high-quality construction material.
  • the plant described makes it possible to increase hourly production of the construction material, while concomitantly reducing energy consumption and the space required at the work-site.
