Embodiment Construction

[0013] See the accompanying drawings: the material enters the membrane frame core (17) through the liquid inlet pipe, and is driven to rotate by it, and the liquid passes through the membrane to form filtration, and the replacement of the membrane frame (17) can achieve the filtration, diafiltration, and nanofiltration of the present invention. Requirements, then pass through the hole blue (16) to the inner cavity of the columnar drum (15), after the separation is formed, it is divided by the light and heavy liquid plates (14), so that the light and heavy liquids go their own way, and then the light (9 ), heavy (8) liquid pumps are discharged outside the machine, and the pump among the present invention can make liquid have certain dynamic head; 19) Out of the machine.

Abstract

The invention relates to a novel centrifugal machine, comprising a material liquid feeding-discharging system, a casing, a transmission system, a rotary drum system, a sediment-discharging system, an electric control system and a sediment-liquid discharging control system. After the rotary drum of the centrifuge is driven by the transmission system to revolve, materials are fed through a material inlet and transferred to an inner cavity of the rotary drum. The material liquid is driven by the rotary drum to revolve and forms a centrifugal force field and generates separation to be separated into liquid-liquid-solid, three-phase. A solid phase is controlled by the electric control system and the sediment-liquid discharging control system and is discharged through a solid-discharging outlet. Both a light liquid phase and a heavy liquid phase are discharged through the material feeding-discharging system, so as to finish the, liquid-liquid-solid, three-phase separation. The invention adopts the sediment-discharging system controlled by a piston valve to complete automatic discharging of the solid phase. A liquid-skimming structure of the material feeding-discharging system can lead the two-phase liquids of different proportions to be discharged respectively. A certain dynamic pressure head is provided for the distance liquid conveying. After a film frame in the rotary drum is changed, the invention can adapt to the process requirements of filtering, leaking filtration and nanofiltration. The invention can be applied to the test, scientific research and manufacture of fine chemistry, biology, environment protection and pharmacy, etc. industries.

Description

technical field [0001] The invention relates to centrifugal separation and centrifugal filtration equipment, in particular to centrifugal separation and centrifugal filtration equipment for automatic slag discharge, and belongs to the category of centrifugal separation and filtration equipment in fluid machinery. Background technique [0002] The current three-legged centrifuge technology is divided into two parts, one is centrifugal sedimentation, and the other is centrifugal filtration, which basically belongs to solid-liquid separation. Some other models are derived from these two models: hanging bag type The centrifuge belongs to the intermittent slag discharge type; the lower discharge centrifuge uses a mechanical scraper to scrape the material; the siphon centrifuge uses a siphon to suck the material. The structural principle limits the application field of the three-legged centrifuge. Can not meet the technical requirements of modern industry. Contents of the inven...
