碟片式离心机是什么?

   What is a disc centrifuge?

　　碟片式离心机是一种立式离心机。滚筒安装在垂直轴的上端，由电机通过传动装置驱动高速旋转。鼓中有一组相互重叠的碟形部件——圆盘。鼓中有一组相互重叠的碟形部件——圆盘。制动盘之间有一个小间隙。悬浮液(或乳液)通过位于滚筒中心的进料管加入滚筒。当悬浮液(或乳化液)流过圆盘之间的间隙时，固体颗粒(或液滴)在离心机的作用下沉降在圆盘上，形成沉积物(或液体层)。沉积物沿着圆盘表面滑动，离开圆盘，并在滚筒中直径大的部分积聚。分离的液体通过液体出口从滚筒排出。

Disc centrifuge is a vertical centrifuge. The roller is mounted on the upper end of the vertical shaft and is driven by a motor through a transmission device to rotate at a high speed. The drum contains a set of overlapping dish-shaped parts called discs. The drum contains a set of overlapping dish-shaped parts called discs. There is a small gap between the brake discs. The suspension (or emulsion) is added to the drum through a feed tube located in the center of the drum. As the suspension (or emulsion) flows through the gap between the discs, solid particles (or droplets) settle on the discs under the action of the centrifuge, forming a deposit (or liquid layer). Sediment slides along the surface of the disc, away from the disc, and accumulates in the large diameter part of the drum. The separated liquid is discharged from the drum through the liquid outlet.

　　圆盘的功能是缩短固体颗粒(或液滴)的沉降距离并扩大转鼓的沉降面积。由于在滚筒中安装了圆盘，分离器的生产能力大大提高。分离器关闭后，应手动除滚筒中积聚的固体，或在不关闭除渣机构的情况下将其从滚筒中排出。碟片式离心机是一种立式离心机。滚筒安装在垂直轴的上端，由电机通过传动装置驱动高速旋转。鼓中有一组相互重叠的碟形部件——圆盘。制动盘之间有一个小间隙。悬浮液(或乳液)通过位于滚筒中心的进料管加入滚筒。当悬浮液(或乳化液)流过圆盘之间的间隙时，固体颗粒(或液滴)在离心机的作用下沉降在圆盘上，形成沉积物(或液体层)。沉积物沿着圆盘表面滑动，离开圆盘，并在滚筒中直径大的部分积聚。分离的液体通过液体出口从滚筒排出。圆盘的功能是缩短固体颗粒(或液滴)的沉降距离并扩大转鼓的沉降面积。由于在滚筒中安装了圆盘，分离器的生产能力大大提高。分离器关闭后，应手动除滚筒中积聚的固体，或在不关闭除渣机构的情况下将其从滚筒中排出。

The function of the disk is to shorten the settling distance of solid particles (or droplets) and expand the settling area of the drum. As a result of the disc installed in the drum, the production capacity of the separator is greatly improved. After the separator is closed, solids accumulated in the drum should be removed manually or discharged from the drum without closing the slag removal mechanism.

　　碟片式离心机可完成两种操作：液固分离(即底部浓缩悬浮液的分离)，称为澄清操作;液-液分离(或液-液-固)分离(即乳液分离)称为分离操作。转鼓配有一堆锥形盘，用于通过离心沉降分离乳化液和低浓度悬浮液的组分。

Disk-type centrifuges can perform two operations: liquid-solid separation (i.e. separation of the bottom concentrated suspension), known as the clarification operation; Liquid-liquid separation (or liquid-liquid-solid) separation (i.e., emulsion separation) is called a separation operation. The drum is equipped with a set of conical plates for separating the components of the emulsion and the low concentration suspension by centrifugal sedimentation.
