Technical Field

The invention belongs to the technical field of centrifuges, and particularly relates to a rotor structure of a horizontal screw centrifuge for processing suspension.

Background

Currently, the current state of the art commonly used in the industry is such that: the horizontal spiral sedimentation discharge centrifuge (horizontal spiral for short) can generate 3000 times of gravitational acceleration by the high-speed rotation of a main rotating part (rotary drum) of the equipment to centrifugally separate solid-liquid two-phase materials entering the equipment, so that the materials which can be slowly sedimented under the original natural condition can be rapidly separated from liquid, and the separation of the solid and the liquid can be realized under the action of an automatic discharge part (spiral) of the horizontal spiral sedimentation centrifuge. The basic requirement that the horizontal decanter centrifuge on the market can process materials is that the solid phase can naturally settle in the liquid phase under the static condition, and the specific gravity of the solid phase is required to be higher than that of the liquid phase. In the market, the centrifugal machine can only separate materials with higher specific gravity of a solid phase than that of a liquid phase, the requirement for separating certain materials with lower specific gravity of the solid phase than that of the liquid phase cannot be met, and the problems of material blockage and escape of the solid phase materials from a liquid phase outlet are easy to occur.

In summary, the problems of the prior art are as follows: in the market, the centrifugal machine can only separate materials with higher specific gravity of a solid phase than that of a liquid phase, the requirement for separating certain materials with lower specific gravity of the solid phase than that of the liquid phase cannot be met, and the problems of material blockage and escape of the solid phase materials from a liquid phase outlet are easy to occur.

The difficulty in solving the technical problems is as follows: how to crouch spiral shell centrifuge's rotor part, like rotary drum and helical structure, mainly reform transform helical blade, helical blade redesign, helical blade's height is less than the height of solid-liquid layering face, makes it can satisfy the material demand that separates some solid phase proportion and be lower than the liquid phase to avoid solid material to pile up in the centrifuge and influence liquid material and discharge and solid phase material escape problem from the liquid phase export and appear. And a baffle plate is welded on the spiral body to prevent the solid from being discharged from the liquid phase, and a scraper is arranged on the baffle plate to prevent the solid from being accumulated at the liquid phase port.

The significance of solving the technical problems is as follows: the horizontal decanter centrifuge can process materials with the solid phase weight being lighter than the liquid phase weight, the problem that the centrifuge can only separate materials with the solid phase weight being higher than the liquid phase weight on the market is solved, and the problems that the solid materials are accumulated in the centrifuge to influence the discharge of the liquid materials and the escape of the solid materials from a liquid phase outlet are avoided.
