Title: Mixed flow pump equipped with volute casing
Inventor: SHIMIZU ISATO
IPC: F04D29/44
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the structural strength of a volute tongue part by forming the tongue part of a volute casing toward an impeller for its hub side and away from the impeller and twisted for its shroud side. SOLUTION: A tongue part 2 and a hub side 6 are formed to be twisted toward an impeller 1 and a shroud side 7 is formed to be twisted away from the impeller 1. Thus, a secondary flow component flowing along the hub side wall 4 of a volute is guided to an inner volute 9. Conversely, a secondary flow component 7 flowing along the shroud side 5 of the volute is guided to an outer volute. A sectional form 18 in a center surface 15 is set in parallel with a flowing direction 13 from the impeller 1 according to designing specifications. The tip of the tongue part 2 is placed in parallel as a whole with a flow combining secondary flow components 12 and 13. Since the sectional secondary moment of the tip part of the tongue part 2 is increased, a rigid structure is provided against shearing forces produced by the secondary flows 12 and 13.  Thus, the strength of the volute tongue part is increased.

Abstract: PURPOSE:To prevent the deposition of a crystal on the apparatus wall and to operate continuously and easily the apparatus by providing an organic solvent supply port below a releasing liquid supply port and above the end part of a downpipe, in the downpipe provided in a mixing vessel of an organic solvent contg. extracted metallic ions and a fluoride releasing liquid. CONSTITUTION:Said organic solvent 2 and a heated fluoride releasing liquid 4 are introduced into a mixing vessel 6 respectively through a supply port 3 and a supply port 5, and agitated and mixed 7 to reversely extract metallic ions in the organic phase into the water phase as fluorides. The liquid 4 whose sp.gr. is increased due to the release of metallic ions flows down in a downpipe 11 while separating the organic solvent and depositing crystals of fluoride having comparatively small solubility. In the apparatus, the supply port 3 is arranged below the supply port 5 and above the lower end of the pipe 11. Accordingly, the retention time of the organic solvent in the vessel 6 is prolonged as compared with the conventional apparatus. Consequently, the crystal particles ascending along with the organic solvent are removed as the particles ascend, and the deposition of the particles on an organic solvent overflow weir 8 and the clogging in the weir by deposition can be prevented.
