PURPOSE: To make the preventing dispersing and adhesion of a solidifying paste possible by surrounding an electrode type level meter detector part detecting the injection amount of the solidifying paste, with a hollow cylinder vessel.
CONSTITUTION: After adding water measured with a water meter 3 into a mixing tank 4, the solidification agent stored in a solidification agent silo 1 is measured with a solidification agent meter 2 and transported gradually into the mixing tank 4 and mixed with a stirrer 5 to form solidifying paste 10. The solidifying paste 10 is injected in a solidification vessel 9 charged with waste 8 through an injection pipe 7 by opening an injection valve 6. At this time an electrode type level meter 11 set for preventing overflow of the solidifying paste 10 out of the solidification vessel 9 controls the injection rate. A protection cylinder 12 surrounds the detector of the level meter 11 to prevent adhesion of the solidifying paste 10 due to dispersion during the injection. A washing valve 14 supplies washing water for washing the level meter 11 to which solidifying paste 10 adhered.
