Basic knowledge of horizontal screw centrifuge

- Sep 01, 2020-

The horizontal screw centrifuge is a new type of equipment derived from the improvement of traditional solid-liquid separation equipment. In comparison, its performance is more powerful, not only more efficient, but also more energy-efficient, and at the same time more secure. For this reason, horizontal screw centrifuges are currently used in starch, chemical and pharmaceutical fields.

Therefore, after a period of development, the horizontal spiral centrifuge has won unanimous praise from customers. However, in order to achieve high-efficiency, energy-saving, and safe solid-liquid separation requirements, we also need to use and operate solid-liquid separation equipment correctly. We know that there are several important parts in the equipment, such as a screw conveyor, the main function of which is to push the sediment.

In order to improve the performance of the horizontal spiral centrifuge as much as possible, the spiral blades equipped therein adopt a continuous integral double-headed spiral blade structure, and they are perpendicular to the axis of the drum. In addition, in order to maintain a proper speed difference between the drum and the screw conveyor, a transmission is also used. The overflow baffle is mainly used to adjust the diameter of the overflow.

Under normal circumstances, if the overflow diameter of the horizontal screw centrifuge is larger, the dryness of the scum obtained is greater. On the contrary, its slag contains more liquid. In addition, the drum used in the equipment adopts a cylindrical-cone combined structure, which can provide favorable conditions for solid-liquid separation.

In addition, when designing the drum barrel of the horizontal screw centrifuge, an annular flange was added to the surface. The advantage of this is that it can prevent the clear liquid from penetrating into the slag discharge chamber. When operating the horizontal screw centrifuge, the user can control the rotating drum speed by adjusting the motor speed to achieve the desired separation effect.
