Problems solved by technology

[0007] At present, in the water treatment process of powdered activated carbon, problems such as blockage, flying dust, and environmental pollution are prone to occur during the powdered activated carbon powder transportation, metering, and preparation processes, resulting in uneven powdered activated carbon powder ingredients and equipment maintenance and management problems.
At the same time, powdered activated carbon cannot diffuse rapidly in water, causing the problem of low utilization rate of powdered activated carbon, which will affect the water treatment effect

Abstract

The invention discloses a powdered activated carbon dosing system with a pre-dispersion and weighing mechanism. The system comprises a powdered activated carbon silo, the bottom of the powdered activated carbon silo is provided with a cone funnel; the bottom of the cone funnel is provided with a cavitation vibration-proof device; the bottom of the cavitation vibration-proof device is connected with a star feeder; the discharge port of the star feeder is in butt joint with a volumetric screw feeder provided with a stock bin; the discharge port of the stock bin is connected with a powdered activated carbon paste pre-dispersion tank; and a pressure pump is connected with the powdered activated carbon paste pre-dispersion tank and an ejector respectively. The powdered activated carbon dosing system can realize whole mechanical and automatic operation during conveying, metering and preparing process of the powdered activated carbon dosing system. A closed structure is adopted by the system. The star feeder controls the amount of discharged materials, thereby preventing the materials from accumulation on a screw conveyer, increasing feeding metering accuracy; and a main screw of the feeder is connected with a stirring screw and a shuffling screw, so that the powdered activated carbon can naturally fill the feeding screw, thereby guaranteeing an accuracy of + / - 1-1.5%.

Description

technical field [0001] The invention relates to the technical field of water treatment in the field of environmental protection, in particular to an automatic preparation and dosing device for powdered activated carbon in water purification or wastewater treatment processes, and in particular to the mechanical connection structure of the equipment. Background technique [0002] Powdered activated carbon is dark black in appearance, has good adsorption performance, good chemical stability, can withstand strong acid and alkali, and can withstand water immersion and high temperature. The filling density is generally 0.32-0.50g / cm3, and the specific surface area is as high as 1000-1500m2 / g. It is a porous hydrophobic adsorbent. [0003] Powdered activated carbon has a strong adsorption capacity for organic pollutants dissolved in water, such as trihalomethanes and precursors, carbon tetrachloride, benzene, and phenolic compounds. It has a good removal effect on chroma, odor, od...
