A present invention provides for a system (100) for injecting cooling fluid into a concrete mixing container (502), the system (100) comprising a support structure (116) having a leg assembly with two or more supporting legs (201) and a cross member beam (200) supported between said two or more legs (201), the two or more legs (201) and the cross member beam (200) being positioned with respect to one another in such a manner as to define a passageway (210) of sufficient height (H) and width (W) between the two or more legs (201) and beneath the cross member beam (200) to allow passage of a concrete mixer truck (504) through the passageway (210) and a lance device (190) positioned on the cross member beam (200) of the support structure (116), the lance device (190) comprising an articulated arm that includes a rigid lance (102) which allows for the flow of a cooling fluid there through; and a means for acting on the articulated arm to cause pivotal movement of the articulated arm in a non-linear motion thereby controlling the angle of the rigid lance (102) while at the same time controlling the insertion and retraction movement of the rigid lance (102) into the concrete mixing container (502) for fluid injection of the cooling fluid into the concrete mixing container (502). The present invention further comprises a process for injecting cooling fluid into a concrete mixing container (502).

La présente invention propose un système (100) pour injecter un fluide de refroidissement dans un contenant malaxeur (502), le système (100) comportant une structure de support (116) ayant un ensemble pied constitué de deux ou de plusieurs pieds de support (201) et une poutre transversale (200) portée entre lesdits deux ou plusieurs pieds (201), les deux ou plusieurs pieds (201) et la poutre transversale (200) étant positionnés les uns par rapport aux autres de façon à définir un passage (210) de hauteur (H) et de largeur (W) suffisantes entre les deux ou plusieurs pieds (201) et sous la poutre transversale (200) pour permettre le passage d'un camion malaxeur (504) à travers le passage (210), et un dispositif de lance (190) disposé sur la poutre transversale (200) de la structure de support (116), le dispositif de lance (190) comportant un bras articulé qui comprend une lance rigide (102) qui permet l'écoulement d'un fluide de refroidissement à travers celle-ci ; et un moyen pour agir sur le bras articulé pour entraîner un déplacement en pivotement du bras articulé dans un mouvement non linéaire, commandant ainsi l'angle de la lance rigide (102), tout en commandant en même temps le mouvement d'introduction et de retrait de la lance rigide (102) dans le contenant malaxeur (502) pour une injection du fluide de refroidissement dans le contenant malaxeur (502). La présente invention comporte en outre un procédé pour injecter un fluide de refroidissement dans un contenant malaxeur (502).
