7. The apparatus of claim 1, wherein the apparatus comprises: and each sample distributing pipe is provided with a medicine inlet, and according to a pH detection result, the sample sending electromagnetic valve is controlled by the control panel to add medicine so as to modify the medicine again.
8. The apparatus of claim 1, wherein the apparatus comprises: the resistivity probe is arranged in the branch pipe connected with the diaphragm pump, and when the resistivity changes, the pipette is automatically retracted, so that the fly ash and the filtrate are prevented from being sucked out by the diaphragm pump.
9. The apparatus of claim 1, wherein the apparatus comprises: the procedure is set, the air inlet electromagnetic valve and the air outlet electromagnetic valve of the centrifugal pipe orifice are automatically opened after modification is completed, the air supply pipe extends into the centrifugal pipe, the hot air dryer starts to work, meanwhile, the detachable filter membrane is arranged below the air inlet and the air outlet, the fly ash is prevented from drifting outside the centrifugal pipe, the drying time and the drying temperature can be set through the control panel, the drying treatment of the sample is completed, the centrifugal pipe with the sample is taken out, and the new centrifugal pipe can be put into the centrifugal pipe to work again.
10. The apparatus of claim 1, wherein the apparatus comprises: this device is equipped with waste liquid discharge port for the water of water-bath heating can directly discharge into the sewer, and if there is harmful substance to the filtrating in the filtrating collecting pit, discharges after handling.
11. The apparatus of claim 1, wherein the apparatus comprises: but this device self-cleaning lets in the running water earlier at each medicine inlet and washs, then lets in the deionized water and rinses, later opens through control panel control air intake solenoid valve and air outlet solenoid valve, and hot air dryer begins work, dries equipment, can work once more. But self-cleaning before carrying out new modification, when guaranteeing the modification effect, both practiced thrift the manpower, promoted work efficiency again, degree of automation is high.
