Description
Technical Field
The invention relates to the technical field of centrifuge equipment, in particular to a wheat starch three-phase horizontal spiral centrifugal machine.
Background
Wheat starch is a white and bright powdery substance, and has the advantages of high transparency, strong and stable viscosity, easy gelatinization and high deformation resistance. The millet starch has unique properties incomparable with other starches, is the most popular basic raw material in the food industry, is widely applied to the industries of food, paper making, textile, clothing, pharmacy, chemistry and the like, and in recent years, along with the development of society and the improvement of living standard of people, the production of refined food, convenient food, health food and nutritional food taking millet flour as a raw material is rapidly increased, the application range of the millet starch is also continuously expanded, and the consumption of the millet starch also tends to rise year by year.
The prior art mainly utilizes horizontal screw centrifuges for producing and purifying wheat starch, and the horizontal screw centrifuges can be generally divided into horizontal screw filtering centrifuges and horizontal screw settling centrifuges. The horizontal screw centrifuge is a horizontal spiral discharging and continuously operating sedimentation device, can separate solid phase and liquid phase in wheat starch in the process of rotating operation, can play a role in separation, but starch and protein still remain in discharged liquid phase, and waste of starch and protein can be caused by directly discharging the liquid phase.
And a three-phase centrifuge is a mechanical device for separating solids from liquids and liquids from liquids by using centrifugal force. The three-phase centrifugal machine is characterized by that after two liquid phases and one solid phase are fed into the centrifugal machine, they are expanded by several thousand times by means of centrifugal force field, the solid phase is settled under the action of centrifugal force, and the two liquid phases are also layered, so that the solid-liquid three-phase separation can be implemented, and can be respectively discharged from machine body under the action of special mechanism. The whole feeding and separating process is completed continuously, closely and automatically. It is mainly composed of drum, screw, differential, machine frame, cover shell and motor.
When the material to be separated is conveyed into the centrifuge drum by the feeding pump, the high-speed rotating drum generates strong centrifugal force to deposit the solid-phase particles with density higher than that of the liquid phase on the inner wall of the drum, and the spiral and the drum have relative motion (i.e. rotation speed difference is adjustable) due to different rotation speeds, so that the solid (slag) with high density is deposited on the drum wall. The two phases of clear liquid of different densities form concentric cylinders, the lighter liquid phase being in the inner layer and the heavier liquid phase being in the outer layer. The thickness of different liquid rings can be adjusted by a liquid adjusting plate (namely the water content in oil or the oil content in water can be adjusted), slag deposited on the wall of the rotary drum is conveyed to the cone end of the rotary drum body by a screw conveyor and is discharged into a solid volume material box from a discharge port, water and oil are respectively discharged from respective outlets, and the whole oil, water and slag three-phase separation process is automatic feeding and automatic discharging.
The three-phase centrifuge is mainly used for clarifying, deslagging and impurity removing three-phase separation of aging oil in an oil field, waste engine oil, waste cooking oil and the like, and the existing three-phase centrifuge cannot be directly applied to the field of production and purification of wheat starch because the quality forms of oil liquid and starch are different, and the most important thing is how to adapt the existing oil liquid separation structure to separation of heavy phase liquid and pentosan wastewater.
