Patent ID: 7695616

Claim:
A device for dissolving a solid chemical substance with water so as to obtain an aqueous solution; the device comprising: a container, which has a collecting portion for containing the aqueous solution, and a loading chamber, which is set above the collecting portion, is designed to contain the solid chemical substance and is provided with supporting means, designed to support the solid chemical substance, and water-dispersion means for directing at least one first jet of water on said solid chemical substance; wherein the water-dispersion means are arranged within the loading chamber above the supporting means and are designed to direct the first jet of water only laterally and/or downwards so as to wet the solid chemical substance; supplying means for supplying the water to the container, drainage means for taking the aqueous solution from the container, level-detection means for detecting the level of the aqueous solution within the collecting portion, a control unit for controlling the supplying means, which is connected to the level-detection means so as to maintain the level of the aqueous solution within the container substantially between a maximum level and a minimum level; and shielding means for shielding said level-detection means from the wave motion of the aqueous solution.
