The invention discloses a hazardous
solid waste pretreatment device. Comprising a collecting opening, a feeding conveying belt, a motor I, a supporting protection plate, a motor II, a blocking rod, a supporting frame I, a supporting frame II, a supporting frame III, a supporting frame IV, a supporting frame V, a main conveying belt, shifting teeth, a storage box I, a storage box II, a storage box III, an acid liquor box, an alkali liquor box, a storage box IV, a fixing mechanism, a cover sucking
pipe, a cover pulling mechanism, a cover screwing mechanism, a PH
detector, a grabbing mechanism and a rack. The collecting opening is fixedly installed on a supporting protection plate, a feeding conveying belt is arranged on the supporting protection plate, one end of the feeding conveying belt is connected with a motor I, and one side of the supporting protection plate is fixedly installed on the
machine frame. By arranging the adjustable flow dividing device, the
reagent bottle sorting device can adapt to
reagent bottles of different specifications, partition plates are arranged on the two sides of the flow dividing device, the
reagent bottles can be effectively sorted, two sets of reagent bottles can be treated at the same time, and by arranging multiple sets of cover opening mechanisms, the reagent bottles of different sizes and different types can be treated.
