The invention discloses a chemical dissolving tank for
sewage treatment, and relates to the field of
sewage treatment. According to the chemical dissolving tank for
sewage treatment, the upper surfaceof a mixing box is fixedly connected with a chemical bin, a shell is arranged in the mixing box, a rotating shaft is connected to a bearing in the shell, an
impeller sleeves the outer surface of therotating shaft, a stirring wheel is fixedly connected to the outer surface of the bottom end of the rotating shaft, a fan-shaped plate is fixedly connected to the outer surface of the top end of the rotating shaft, and a water outlet is formed in the bottom of the mixing box. According to the chemical dissolving tank for
sewage treatment,
water flow enters the shell through a water inlet
pipe anddrives the rotating shaft to rotate through the
impeller in the flowing process, a sector plate rotates with the rotating shaft as the axis in the lower part of a
discharge port, and the
discharge port is used for intermittent
discharge. Meanwhile, a chemical which is not dissolved in time is precipitated to the bottom of the mixing box, is positioned on the upper surface of the filter plate and is stirred through the stirring wheel, so that the chemical and the
water flow are synchronously added and stirred to be dissolved, and the blockage of the water outlet caused by accumulation of the chemical at the bottom is avoided.
