The utility model discloses a chemical
raw material storage tank which comprises a
temperature control main tank body and a tank top cover installed on the top of the
temperature control main tank body, a feeding
barrel is installed in a tank cavity of the
temperature control main tank body in a supporting mode through a supporting rod frame, and a bottom discharging
barrel is installed at the bottom of the temperature control main tank body. A feeding and discharging shaft is rotatably mounted at the center of the tank top cover through a bearing, the top end of the feeding and discharging shaft is connected with a driving
assembly mounted above the tank top cover, and the bottom end of the feeding and discharging shaft passes through the feeding
barrel and extends into the bottom discharging barrel. An umbrella-shaped annular wall is fixedly arranged on the top of the outer side barrel wall of the feeding barrel in a sleeving mode, a feeding
auger is installed on the portion, in the feeding barrel, of the feeding and discharging shaft, and a discharging
auger is installed on the portion, in the bottom discharging barrel, of the feeding and discharging shaft. The feeding device has the beneficial effects that discharging is convenient through the packing augers in the opposite direction, temperature control is faster and more uniform, center feeding is achieved through the feeding packing
auger in the center, the driving resistance is small, and the driving requirement cost is low.
