Suspension dispersion liquid extraction device

The utility model discloses a suspension dispersion liquid extraction device which comprises a base, a supporting plate is fixedly connected to the middle of the top end of the base, a sliding rod isfixedly connected to the top end of the supporting plate, and a connecting block is fixedly connected to the top end of the sliding rod. When the device is used, when dispersion liquid needs to be extracted, the extraction cup is fixed through the first clamping plate and the second clamping plate and stands still for a period of time to wait for dispersion liquid layering, then the hand wheel isshaken, the extraction pipe descends to the liquid level layering position at the moment, the water pump is started, dispersion liquid on the upper layer is pumped out, and supernatant liquid is collected through the collection bottle; compared with an existing extraction device, the continuous extraction device has the advantages that the dispersion liquid can be extracted step by step, manual guarding at any time is not
