Description

"High speed dryer for bricks and method for their production".
Field of the invention.
The invention refers to a plant for drying the bricks in extremely fast mode and to the method of production able to make such processing. With the invented dryer final products are obtained rapidly and with particular dimensions and sizes.
State of the art before the invention.
In the field of the dryers a lot of proceedings are known for the production of bricks wherein, after drilling at wet and before the cooking in specific ovens, said bricks are placed in dryers with hot air currents in order to remove the moisture that evaporates from the surface of the pieces. The evaporation phenomenon is made up continuously, till the complete drying of the pieces, from the water vapor transport from the inside of the material to its outside surface, for the effect of heating that the piece suffers owing to the heat transferred from the air current with which comes in contact. It has particular importance the continuity of the evaporation process to have a rapid drying process and without waste on the finished product. The presence of different heating in different parts of the product causes, in fact, tensions on to the product which would alter its size and its structure. The plants for drying of bricks have in the time undergone several transformations and evolutions. It has gone from dryers of big dimension, with drying time from eight to sixty hours, where the drying time changes in relation to the kind of clay to be treated and to the kind of piece to be dried, till to arrive to the more efficient semi-rapid type systems with drying time of three to six hours and to the super-rapid types with rollers with drying time of forty-five to ninety, hundred and twenty minutes. The difference of permanence of the pieces into the dryer is not only due to the physical characteristics of the clay mixture and to the geometry of pieces but also and in particular to the temperature and moisture uniformity between the different parts of the piece to be dried. A drying process which ensures, during all the cycle, uniformity of temperature and constant moisture content into the piece permits to arrange a fast drying. This fast drying process, considering the characteristics of the material and the geometry of the piece, also ensures a total absence of cracks during the drying process. It may occur cracks during the drying those manifest not so much for the fast of the process but principally for the different contractions which suffer the different parts of the same piece when they are at different temperatures and with different water quantity content, those depend from different and not uniform distribution of the air used in the process for the piece to be dried. For the different drying systems used until today the one that is closest to realize the perfect conditions of high uniformity of the thermos-hygrometric conditions is currently the roller fast dryer. This plant consists of a tunnel containing a carpet of rollers to transport the pieces with a width from two to four meters and a length of approximately hundred, hundred and twenty meters with hot air introduced into the tunnel in correspondence of the exit of the dried pieces. In entrance the pieces to be dried are automatically introduced by an automatic system. The rollers movement is in continuous and it is arranged with variable speed from zone to zone, with at least five zones usually realized in the length of the dryer. The temperature of the air in entrance, with the direction opposite to the advancement of the pieces, has values one hundred and fifty to one hundred and eighty Celsius degrees while the air temperature at the entrance of the introduced pieces has values comprise from forty to fifty Celsius degrees. The air extraction is arranged by one of more centrifugal ejecting fans, those are apparatuses with high aerodynamic performance. The ventilation system is dimensioned in such a way to guarantee s speed of the air lapping the pieces to be dried at approximately twelve, twenty meters per second. The rollers dryer, however, has a lot of disadvantages. In fact into the rollers dryer the pieces to be dried cannot have dimensions lower than two hundred millimeters in the sense of the ventilation. Other disadvantage of the rollers dryers is given to the fact that in this kind of dryer the width to load the e pieces cannot be more than four meters to not have bending problems of the rollers. Said bending, in particular way for pieces of high weight, determines movements for some files toward the sides of the dryer tunnel, with obvious effects of misalignment and in particular for rotation of the pieces of many degrees, i.e. from twenty to thirty degrees with different ventilation inside the pieces. This determines cases of obstruction of the air flow with damages of the adjacent pieces submitted to different drying and problems with the automatic unloading of the dried pieces with real stops of the production. The pieces disposition onto the rollers than obliges to place the pieces onto the bigger side of the pieces, with sole possible direction in comparison with the hot air flow.
Summary of the invention.
These and other disadvantages of the known dryers are solved from the invented dryer. The invented dryer realizes the same hygrometric and aerodynamic conditions of the roller fast dryer but with the pieces those can be of any size and dimension e for all kind of bricks. The invented dryer is arranged with a new support and transport system of the pieces to be dried and it is able to avoid all the limitations of the roller plant. In particular the invented dryer permits to have drying cycle very fast, with time lower than sixty minutes, without cracks into the pieces also for bricks having a drilling percentage very high, realized with numerous very thin septums as in the modern block of bricks, i.e. thermal insulating blocks with high characteristics thermal and acoustic insulating. Other advantage of the invented dryer is given to the fact that permits a most loading of the pieces to be dried. Other advantage given to the invented dryer is that the optimal distribution of the hot air in the introduced pieces reduces significantly the defects of the obtained products, having the possibility to place the pieces to be dried in any way and having the possibility to use entirely the width of the drying tunnel to increase the workload of the plant. Further other advantage arranged to the invention given to the fact to can load into the drying tunnel more transport platforms of the pieces to be dried. The high speed dryer for bricks comprises a heat generator, one or more introducing fans for hot air in the opposite direction respect to the advancement of the pieces to be dried, one or more ejecting fans and it consists of a trolleys to support the pieces to be dried arranged with one or more platforms placed onto trolleys, with the trolleys having wheels suitable to slide onto tracks placed inside the dryer. The high speed dryer provides then a proceeding for the production of bricks consisting of: a) loading of the pieces to be dried with automatic apparatus, as for example a robotic gripper, b) placing incoming of the pieces to be dried placed onto platforms in rows and columns aligned with boring in favor of the hot air flow to be placed by the trolleys inside the drying tunnel, c) incoming from the opposite end in comparison with that of incoming of the pieces to be dried of a hot air flow with working speed onto the pieces to be dried from fourteen to twenty meter per second, with low humidity in entrance and temperature variable from one hundred and fifty to one hundred and eighty Celsius degrees, with the volume of the air current that is in function of the type of the clay and of the pieces to be dried, having a value in average comprises from two hundred to two hundred and fifty cubit meter per minute for ton for hour of dried material, d) expulsion of the moist air by the dryer inlet by one or more ejecting fans, e) advancement of the trolleys inside the dryer such as at the entrance of the first correspond the exit of the last from the opposite end, f) recovery via return line of the outgoing trolleys from the dryer extended up to the loading point of the pieces to be dried, g) unloading of the dried pieces with automatic apparatus, such as a robotic gripper. These and other advantages of the present invention are better evident from the following detailed description of a preferred but not limiting embodiment, with the enclosed drawings those show the invention in indicative way e so no limiting.
