The present invention relates to a method of a preparation and continuous saponification extraction of an ammonia-calcium compounded saponification agent. The method is to mix an ammonium salt solution with calcareousness to prepare for an ammonia-calcium compounded solution, which is filtrated or clarified to obtain an ammonia-calcium clarifying solution. The clarifying solution and an organic phase are continuously saponified. The loaded organic phase is countercurrent washed to doff ammonia by a calcium salt solution inside a 1 to 10 grade extraction groove. The saponified organic phase is mixed with a solution for extracting to make extraction separation and reverse extraction. The present invention uses the easily-obtained and low-cost calcareousness as the raw material to reduce the saponification cost during the course of extraction separation. The clarifying solution is adopted for saponification, which eliminates the rigorous requirement towards the raw material of the calcareousness and shortens the mixing time of a saponification reaction and reduces the loss or an aftertreatment of the organic phase, which is convenient for using during the continuous extraction separation. All calcium hydroniums and ammonium hydroniums are recycled. No ammonia-nitrogenous wastewater is produced during the courses of saponification and extraction, which can eliminate the environmental pollution from the ammonia-nitrogenous wastewater and save a plurality of disposal costs of waste water, gas and residues.

The invention discloses a variable-wheelbase obstacle-surmounting omnidirectional chassis of an industrial robot, and is used to solve the technical problem that the existing omnidirectional chassis of an industrial robot is poor in obstacle-surmounting ability. The technical scheme adopted by the invention lies in that the front and rear wheelbase of the omnidirectional chassis can be changed. In addition, support legs are respectively mounted at four corners of the chassis. When not used, the support legs can be folded to reduce the occupied space; and when used, the support legs can be unfolded. After the support legs are unfolded, the support legs can extend downward to lift the whole chassis off the ground. When encountering obstacles, the support legs are unfolded to surmount the obstacles, and then lift the whole chassis off the ground; at this time, the wheelbase is changed, so that the wheels can surmount the obstacles; and after the obstacles are surmounted, the support legs are folded, and the chassis falls back to the ground to continue to move. For this reason, through the adoption of the variable-wheelbase obstacle-surmounting omnidirectional chassis disclosed by the invention, the obstacle-surmounting function of the omnidirectional chassis of the industrial robot is realized.
