FIELD OF THE INVENTION
[001] The following specification for Utility Model relates to a structural arrangement applied to a gravimetric asphalt plant, the arrangement being solidary to a mobile chassis transported either by road on a semi-trailer (A) validated either to transit without vehicle escort or in its stationary version for producing HMA (Hot Mix Asphalt Concrete) for obtaining mixtures of stone aggregates with (PAC) (Petroleum Asphalt Cement).
BACKGROUND INFORMATION
[002] An asphalt plant can be considered as the heart of the paving works, since it is the equipment in charge of producing the asphaltic mix to be conveyed to all the locations where it will be applied besides the building sites. The fair performance of asphaltic coatings depends on the utilization of the right procedures in several steps: structural design, the right choice of materials and formulations of amounts or mixes suitable to the determinants.
[003] There are two basic types of asphalt plants, the plant using gravimetric or batch production, to produce intermittently pre-set amounts of asphaltic mass (HMA) and the continuous production plant, as explained by the classification itself.
[004] These plants are variable in terms of production capacity and weighing principles and dispensing of materials making up the asphaltic mass (HMA), the plants being either mobile or stationary.
[005] Asphalt plants can be classified by other criteria such as the drying process (parallel flow or counter flow) and mixing process (internal or external to the aggregate drying drum), however the most important classification relates to the dispensing of the mineral aggregates.
[006] Asphalt plants are fitted with individual dynamic weighing for each of the aggregates.
[007] The weighing system for dispensing materials consists basically of weight sensors (load cells) supplied individually at each dispensing belt and linked to a microprocessor in charge of surveying the withdrawing and dispensing of aggregates following pre-set amounts.
[008] Analogously, the system also monitors the amount of petroleum asphalt cement (PAC) to be dispensed to the aggregates.
[009] By continuously monitoring this process, the program will automatically make the corrections required to keep the proportionality of the mix.
[010] For example, when for a certain kind of aggregate a dosage of 20%
is specified the controller will monitor the extraction of same by means of the corresponding load cell; in case the weight exerted on the cell is reduced by 2%, the controller will make the necessary adjustment by increasing the speed of the belt also by 2%, thus keeping the desired aggregate flow rate.
is specified the controller will monitor the extraction of same by means of the corresponding load cell; in case the weight exerted on the cell is reduced by 2%, the controller will make the necessary adjustment by increasing the speed of the belt also by 2%, thus keeping the desired aggregate flow rate.
[011] A mobile gravimetric plant for the production of hot asphaltic mass is described in US patent 5362193 as a mobile, self-erecting gravimetric plant for the production of asphaltic mass and wherein the various plant components are divided into two semi-trailers that are interconnected to form an operational plant, the plant being erected into its functioning position as an unit. The elevator is separately transported and connected to the main structure so as to be lifted to an operative vertical position adjacent the plant.
[012] US patent 2945683 discloses a mobile gravimetric plant for asphalt, with improvements in road construction equipment and is more closely related to improvements in the construction and operation of mobile asphaltic mix plants.
[013] US patent 2805052 discloses a mobile gravimetric plant which partially incorporates the components to perform the machining process of the asphaltic mass in one single semi-trailer making its transportation a little easier, but dispensing with those required to accomplish the complete process.
[014] Additional mobile asphalt plants can be found in documents US

[015] The state-of-the-art technique related to the present subject matter comprises mobile gravimetric asphalt plants that generally include two or more semi-trailers, on which are adapted all the systems and equipment to the desired end.
[016] The devices described hereinabove are generally satisfactory for medium capacity plants, but have drawbacks resulting from their exaggerated weight, design and plurality of semi-trailers required. This fact makes it necessary to utilize cranes and/or other elevation means to perform their assembling/de-assembling, making them cumbersome and expensive, besides requiring extended periods of time to perform their transportation between the sites where they should work.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[017] Thus, on the basis of considerations related to the previously discussed state-of-the-art technique, one of the objectives of the present Utility Model is the development of a gravimetric asphalt plant, the main improvement of same being the provision of a mobile plant comprising a single semi-trailer vehicle incorporating all the systems and components essential for the processing of asphaltic mixes by the gravimetric process, such plant being easily transported without the need of an escort from one location to another as an independent unit, dispensing with external cranes or similar devices.
[018] The characterization of the present Utility Model is fulfilled by means of Figures representative of the structural arrangement applied to a gravimetric asphalt plant, of similarity such that the device can be integrally reproduced by a suitable technique, enabling full characterization of the functionality of the claimed subject matter.
[019] The specification is based on the Figures that have been devised to express the best mode or preferred mode of the devised product by means of a detailed, consecutive numbering, the numbering making clear some features that could be implied by the adopted representation so as to clearly set forth the claimed legal protection.
[020] The Figures are merely representative, many variations and modifications being allowed without departing from the spirit and scope of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED MODE
[030] In accordance with the attached Figures, the plant performs the asphaltic concrete production process on a gravimetric basis, the overall equipment being transported by a road chassis of the kind of a semi-trailer (A) approved for use without a vehicle escort. The plant comprises:
[031] Feeding and pre-weighing: supplied by four dispensing silos 1 provided with four dispensing conveyor belts 2 and connected by a conveyor belt 3;
[032] Drying and heating of aggregates: supplied by a counter flow dryer 4 and its respective burner 5 and gas exhaust 6;
[033] Transfer of hot aggregates: supplied by a dual assembly of extractor belt conveyors 7 and output sieve 8;
[034] Classification and final weighing: supplied by two vibrating sieves 9 provided with a set of four sieves 10 each, eight hot silos 11, provided with dispensing gates 12, and eight scale silos 13 with their respective discharging gates 14;
[035] Mixing: supplied by feed belt 15, dispensing pump 16, mixer 17 and extraction gate 18;
[036] Loading of trucks: supplied by drag elevator 19 and anti-segregating pre-silo 20;
[037] Environmental control and recycling: supplied by bag filter 21 and screw conveyor 22; and [038] Operation cab: contains all of the controls and electrical and electronic systems required for the plant operation, identified as a whole by reference sign 23.
[039] For the feeding and pre-dispensing of aggregates the plant incorporates four dispensing silos 1 to supply same during operation.
Aggregates are extracted from said silos with the aid of dispensing conveyor belts 2 placed underneath each of the silos.
[040] Each dispensing conveyor belt 2 is provided with load cells which perform a pre-dispensing of each of the aggregates individually by means of an electronic flow rate control keeping the proportionality between the aggregates so as to secure the maintenance of pre-set values.
[041] After the different aggregates are classified, the same are conveyed through a conveyor belt 3 into counter flow dryer 4 and together with burner are heated to the temperature specified by the industrial project.
[042] The so-heated aggregates are sieved through an output sieve 8 and are classified according to their granulometric size into two groups, coarse and fine, each of them formed by a plurality of sizes, and are subsequently transferred by two extractor conveyor belts 7 to vibrating sieves 9 positioned side by side to dryer 4, the same being provided with a set of four sieves 10 each.
[043] The final classification is performed on this set of sieves 10 that, being submitted to mechanical vibration, make that the aggregates precipitate through them, being thus classified by granulometric sizes, separating those of irregular size or undesired geometric shape and conveniently storing the remaining ones in eight hot silos 11 positioned immediately underneath both vibrating sieves 9.
[044] Hot silos 11 incorporate tilting dispensing gates 12 to enable the aggregates dispensing to be controlled by the weighing system.
[045] Eight scale silos 13 provided with load cells and positioned underneath the hot silos 11 enable, together with the plant weighing system, the individual and simultaneous dispensing of the aggregates through said dispensing gates 12 until the previously weight set for each one is attained.
[046] Through the discharge gates 14 aggregates contained in the eight scale silos 13 are discharged on feed belt 15 in order to convey same up to arm and blades mixer 17 assembled on parallel shafts.
[047] Mixer 17 is in charge of homogeneously mixing the already heated, weighed and classified aggregates with a pre-set amount of PAC
(Petroleum Asphaltic Cement).
[048] To this end a dispensing pump 16 controlled by the plant electronic control system injects the liquid PAC in a pre-set amount.
[049] After mixing aggregates and PAC, an extraction gate 18 positioned at the bottom of the mixer will enable the so-called asphaltic mass to reach the Redler-type drag elevator 19 that stores said mass in the anti-segregation pre-silo 20 in order to load the trucks.
[050] During the aggregate heating process within the counter flow dryer 4, aggregates are exposed to a hot gases stream produced by the plant exhaust 6 with the result that a significant amount of dust from the aggregates migrates through its exhaust system.
[051] In order to filtrate and recycle said particulates, gases from counter flow dryer 4 pass through bag filter 21 whereby the dust precipitates at the bottom of same and is directed towards the output sieve 8 with the aid of screw conveyor 22 to direct the same to recycling so that they do not escape to the atmosphere.
