Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of scale inhibitor dosing, particularly to a scale inhibitor precise quantitative dosing device. BACKGROUND

[0002] In the field of industrial production and water treatment, calcium, magnesium and other ions in water are easy to form scale layer on the surface of pipeline and equipment, affecting the normal operation and service life of the equipment. Scale inhibitor can effectively prevent the formation of scale, and its precise quantitative dosing is crucial to ensure the treatment effect, reduce cost and avoid waste of reagent.

[0003] The existing equipment usually only provides manual weighing and dosing of scale inhibitor. However, the manual dosing method needs to be worked repeatedly and continuously, and errors are easy to occur due to fatigue after long time work, which cannot meet the demand of precise and quantitative addition of scale inhibitor at regular intervals.

[0004] The existing patent (publication number: CN219823884U) provides a high-silicon scale inhibitor dosing device, relating to the technical field of high-silicon scale inhibitor, which comprises: a bottom plate, a plurality of first support columns are uniformly fixedly connected to the upper surface of the bottom plate, a plurality of second support columns are uniformly fixedly connected to the upper surface of the bottom plate near the inner side of the first support columns; a liquid storage assembly. In the utility model, the high-silicon scale inhibitor in the liquid storage tank flows out into the liquid collecting tank through the liquid outlet valve from the dripping funnel, and the adjustment of the position of the floating plate is driven by the change of the liquid level inside the liquid collecting tank. In combination with the work of the first trigger switch, the second trigger switch and the electric control valve, automatic dosing and closing of the electric control valve can be completed when the preset liquid level in the liquid collecting tank is reached, thereby achieving the purpose of automatic and quantitative dosing of high-silicon scale inhibitor for boiler equipment at regular intervals, and solving the problem that the manual dosing method in the background art cannot meet the demand of precise and quantitative addition of scale inhibitor at regular intervals.

In addition, the liquid storage tank lacks a stirring structure, which may cause the scale inhibitor to precipitate, affecting the scale inhibition effect.

[0006] Therefore, a scale inhibitor precise quantitative dosing device is proposed. UTILITY MODEL CONTENTS
