Definitions

  • the invention has as its subject a ventilation device for drying bricks utilizable, in particular, in drying chambers where the bricks are stacked in superposed rows on a number of parallel frames.
  • Ventilation devices are currently used in the aforementioned drying chambers which are made to slide, in the two directions, in the corridor existing between two facing frames on which there are superposed rows of bricks and these, by contributing to an increase in the relative velocity between the hot air and the article to be dried, guarantee a faster drying of the said bricks.
  • Another method comprises a number of fans, of a small diameter, placed vertically one on the other and fixed to a vertical stanchion which is turned by a rack, when hitting against corresponding fixed limit devices placed at the extremities of the path followed by the carriage that carries the said fans, through 180° thereby directing the flow of air from the fans (which in this method rotate constantly in one and the same direction) alternately towards the fac- i ng rows of bricks arranged on the said frames.
  • This method requires, however, the rack coupling member to be oversized in order to prevent it from breaking where the limit knock takes place and, therefore, at the very time rotation starts, because of the considerable inertia of the masses that are moving.
  • the object of the present invention is, therefore, to overcome the aforementioned difficulties through the construction of a ventilation device, in particular for drying bricks, which allows the rotation and orientation of the ventilation element or elements at the most suitable angle and, contemporaneously, the said position to be stably kept, not only in the region of the extremities but also along the path followed by the said device, and this by means of mechanical methods that are extremely simple and are also financially advantageous , above all in relation to the results obtained therewith.
  • the device in question comprising a stanchion supporting one or more vent- i lation elements, characterized by the fact that it comprises: a first frame integral with the said stanchion, resting, through clutch means, on a second frame integral with a carriage movable, alternately in the two directions, longitudinally along the corridor existing between two facing frames on which there are a number of superposed rows of bricks, and rotatable, with respect to the said second frame, around a vertical spindle; a rotation arm integral, at one extremity, with the lower part of the said vertical spindle, the free extremity thereof being provided with a projection placed at a level lower than the horizontal plane defined by the lower free extremity of the said spindle; and means for guiding and intercepting the said projection, placed beneath the said second frame and at least in proximity of the travel extremity of the said carriage.
  • the said guide means can, when necessary, be placed along the whole path followed by the carriage (or even partially), in such a way as to bring about
  • a further advantage of the device in question lies in the fact that the bricks at both extremities of the frames receive the ventilation flow.
  • the stanchion in fact, always rotates 180° in the same direction, and this is something that was not achieved with the devices that preceded the present invention.
  • a vertical stanchion with which one or more fans 2 are integral (the actual number depending upon the height of the frames 3 and 4 that contain the bricks to be dried, see Fig. 2), fixed to the upper part of a horizontal disk 5 belonging to a first frame, and resting, with the lower surface 6, via a clutch member 7, on the horizontal upper surface 8 of a second frame, shown generally at 9, the upper part of which integral with a carriage 10 movable alternately, in the two directions shown with the arrows 11 and 12, in the corridor existing between the two facing frames 3 and 4, parallel thereto.
  • the rotation of the vertical stanchion 1 around the vertical axis y-y is achieved through a spindle 13, coaxial to the disk 5, and is guided by a pair of bearings 14 placed in the inside of the cylindrical body of the frame 9.
  • the said spindle 13 projects out of the frame 9 and the lower part extends underneath the carriage 10 and has, integral with its extremity, an arm 15 which, in turn, is provided at the free extremity thereof with a roller 16 placed at a level lower than that of the horizontal plane defined by the lower extremity of the said spindle 13.
  • Fig. 2a two guides, 20 and 21, (in this specific instance shaped as shown) are placed at the two extremities of the path followed by the carriage 10 in order to intercept the roller 16.
  • the said guides slope with respect to the direction in which the carriage travels and extend on opposite sides with respect to the line x-x defined by the move- me nt of the axis of the spindle 13.
  • the said guides are interspaced at a distance at least identical to the diameter of the said roller, so as to allow this to pass.
  • the invention can also adopt forms differing from what has been described above and, in particular, numerous modifications of a practical nature may be made, just as the guides 20 and 21 may be of a curvilinear conformation in such a way as to globally achieve a rotation of 180° on the part of the stanchion 1, even though the individual rotations may not be 90°, without in any way deviating from the framework of protection afforded to the invention.
