Abstract:
1. A chemical analysis apparatus comprising a reaction container containing therein a substance to be analyzed, said reaction container being located in fluid of an analysis tank, an agitating mechanism spaced from the substance to be analyzed, for mixing a mixture of the substance to be analyzed and liquid together in the reaction container and agitating them, and a measuring portion for measuring physical properties of the substance to be analyzed, wherein said agitating mechanism has both a sound supply portion adapted to irradiate sound waves unilaterally in one direction through the mixture to apply a lateral sound-wave force to the mixture, and a reflector disposed on an internal wall of said analysis tank, on a substantially opposite side to said sound supply portion with respect to the reaction container, the reflector including an upper and a lower flat reflector surfaces which intersect each other and which are each slanted relative to the internal wall of the analysis tank, where each of the upper and lower flat reflector surfaces reflects the sound waves irradiated through the mixture, to the other of the upper and lower flat reflector surfaces, and the other of the upper and lower flat reflector surfaces reflects the sound waves back toward the mixture at a vertical location which is separated from a vertical location where the sound wave is irradiated, so as to introduce said reflected sound waves again into the mixture to apply a reflected lateral sound wave force to the mixture in a direction opposite to the one direction, where the sound waves and reflected sound waves are applied without counteracting sound waves and counteracting reflected sound waves from opposing sides of the reaction container, and where a combined force of the lateral sound-wave force applied by the sound supply portion and the reflected sound-wave force applied by the reflector, induce a swirling circulation flow of the mixture of said liquid and said substance around an inside of said reaction container.
