Description

Technical Field

[0001] The utility model relates to the technical field of rust inhibitor mixing devices, in particular to an anti-sulfur and anti-corrosion rust inhibitor mixing device. Background Art

[0002] Anti-corrosion and rust inhibitors can be widely used in reinforced concrete structures in adverse geological areas and marine waters such as coal-bearing strata containing sulfate, magnesium and chloride ions, sulfide ore strata, gypsum strata, silt carbon layers, saline land areas, salt lakes, coastal salt pans, coastal ports, seawater infiltration areas, etc., to protect reinforced concrete structures and extend their service life. At the same time, anti-sulfur agents are added to the rust inhibitor to achieve anti-sulfur, anti-corrosion and rust inhibition effects. After searching, the prior art (application number: CN202120455055.7) records "a precise dosing device for anti-corrosion and rust inhibitors, including a mixing barrel, a squeeze box is fixedly installed on the top of the mixing barrel, a funnel is fixedly installed on the top of the squeeze box, a material drawer is movably connected in the inner cavity of the squeeze box, and a hydraulic rod is fixedly installed on the inner side of the material drawer. The utility model pushes the rust inhibitor to the cutting plate by a hydraulic rod, squeezes the rust inhibitor, squeezes the loose powdered rust inhibitor into blocks, and then uses the cutting plate-shaped rust inhibitor for cutting. Under constant pressure, the powdered rust inhibitor will be squeezed into blocks with regular density and rectangular shape. When the block rust inhibitor is cut, it is convenient to accurately control the overall feeding amount of the rust inhibitor, improve the accuracy of the rust inhibitor ratio, and avoid the problem of uncontrollable feeding amount when the loose powdered rust inhibitor is processed and directly dumped manually."

[0003] However, although the precise dosing device of the anti-corrosion and rust inhibitor in the prior art has improved the accuracy of the matching ratio, it still has some shortcomings: the existing rust inhibitor modulation device generally uses a quantitative feeding device to accurately control the amount of the agent to be prepared, and the cutting process in the above device cannot achieve finer powderization of the solid rust inhibitor, thus affecting the dissolution efficiency. Secondly, the existing mixing and stirring is only stirred in one dimension, and the powder is easily not collided and cut with the stirring blade under the action of the centrifugal force of the solution, and there will also be bottom precipitation, resulting in poor mixing efficiency.
