Abstract (en)

A melting chamber to homogenize and heat a ground marking composition in liquid/pasty form comprises a vertical tank (1) to receive the composition, a heating- and an agitating device (8), where the tank has a cylindrical side wall fixed at bottom of the tank. The agitating device comprises a central shaft (9) extended coaxially with the side wall of the tank, an engine (14) fixed at the upper end of the shaft to activate the rotation of the central shaft, and two perforated discs (10) circulated parallelly to the bottom of the tank by the central shaft. The melting chamber to homogenize and heat a ground marking composition in liquid/pasty form, comprises a vertical tank (1) to receive the composition, a heating- and an agitating device (8), where the tank has a cylindrical side wall fixed at bottom of the tank. The agitating device comprises a central shaft (9) extended coaxially with the side wall of the tank, an engine (14) fixed at the upper end of the shaft to activate the rotation of the central shaft, and two perforated discs (10) circulated parallelly to the bottom of the tank by the central shaft. The lower disc is adjacent to the bottom of the tank and separated from the bottom of the tank by a distance smaller than the separation from the upper disc. The discs comprise angularly and radially equal holes. The bottom of the tank is connected to the side wall of the tank by a truncated part, which is widened upwards. The lower disc is located at the level of the truncated part and has a diameter lower than diameter of the upper disc. The central shaft contains two radial blades inclined in opposite directions and placed above the upper disc. The heating device comprises a combustion chamber placed at the bottom of the tank and around the lower part of the side wall of the tank, a burner connected to the combustion chamber, an energy source to supply energy to the burner, and a fume evacuation device. The fume evacuation device comprises an annular space connected to the combustion chamber in which the space is externally surrounded to the side wall of the tank, and an exit located at the upper end of the tank. The annular space contains baffle vertical walls. The annular space is externally delimited by a cylindrical wall, which is covered by an insulating material placed in a protection cover.
