HIGH EFFICIENCY DEWATERING DECANTER CENTRIFUGE TO IMPROVE DEWATERABLITY

摘要

According to a high-efficiency centrifugal dehydrator for improving dewaterability of the present invention, a single ring-shaped blocking plate is disposed between a sludge discharge port of a screw conveyor in a centrifugal dehydrator drum and a cake discharge port of the drum so that a dehydration area in the drum can be narrowed, the pressure of the screw conveyor is maximized, and dehydration efficiency can be increased. Also, the conical angle of the drum having a conical shape is adjusted to be increased so that the dehydration area is narrowed and a filtering area is lengthened, the dehydration effect is increased by raising the pressure received by the dehydration area, a filtrate treatment performance is improved, and a sludge treatment amount is increased. The ring-shaped blocking plate that is applied to the present invention is made of stainless steel, and maximizes the dehydration effect by separating a solid material from filtrate, narrowing the dehydration area, and receiving a higher pressure. The outer diameter of the blocking plate is changed by the volume ratio of the concentration of the sludge to be treated and can vary by centrifugal dehydrator model. Also, an additional suspension separation means is configured to be in the drum according to the present invention.
