Portable three-phase settling disk centrifuge internal flow passage structure

Abstract

The invention discloses a portable three-phase settling disk centrifuge internal flow passage structure. A liquid inlet-outlet diverter valve and a heavy-fluid centripetal pump are connected in a sealing assembling way; and a mixed liquor passes through a liquid inlet pipe in the middle of the heavy-fluid centripetal pump so as to enter a liquid inlet chamber between a gravity disk and a disk fixed plate. The disk fixed plate is arranged at the top end of a settling disk area; the gravity disk is arranged above the disk fixed plate; the mixed liquor enters a rotary drum through the chamber; aheavy-fluid runner is arranged between the gravity disk and the centrifuge rotary drum; a heavy fluid enters a heavy-fluid jet pipe through the runner, is then extracted into the liquid inlet-outlet diverter valve through the heavy-fluid centripetal pump, and is discharged through a heavy-fluid discharge runner; a light fluid outlet runner is located on the lowest part of the settling disk area located near the rotation center of the centrifuge rotary drum; and no falling hole is formed in a disk of the settling disk area. According to the portable three-phase settling disk centrifuge internalflow passage structure provided by the invention, the devices such as the falling hole, a falling baffle plate and a flow guiding plate are omitted, so that the occurrence of the phenomenon that fiber substances frequently mixed in the mixed liquor cause the blockage of the falling hole, the falling baffle plate and the flow guiding plate can be avoided.

Description

technical field [0001] The invention belongs to the technical field of centrifuges, and in particular relates to an internal channel structure of a portable and movable three-phase settling disc centrifuge, which is suitable for applications requiring different densities of the phases to be separated, and the density of the solid phase must be greater than any one of them. In case of liquid phase. Background technique [0002] The settling disc centrifuge can quickly and continuously separate solids and liquids, liquids and liquids, solids and two liquids with different specific gravity. The specific gravity of the solid must be greater than the specific gravity of the liquid to be separated. Food and industrial industries have a wide range of applications. At present, there are mainly two types of decanter centrifuges in the domestic and foreign markets: one-way heart pump centrifuges and two-way heart pump centrifuges.

AI Technical Summary

Problems solved by technology

[0007] The present invention aims at the problems caused by the complex structure of the flow channel in the above-mentioned unidirectional heart pump centrifuge and bidirectional heart pump centrifuge, the blockage of the blanking hole by fibrous substances, and the connection between the light liquid outlet hole and the disc chassis and the drum. Improve the internal channel structure of the centrifuge due to problems such as blockage, heavy equipment, large volume, and unsuitability for mobile work scenarios
