Description

Continuous centrifuge

The present invention is a technical field of a continuous centrifuge, in particular, it is applied to a liquid phase having a different specific gravity, which is accelerated by centrifugal force and can be driven to a continuous operation.

In the mixed liquid, in order to quickly separate the two liquids having different specific gravities, several ways can be adopted: as shown in FIG. 1 , a motor 11 drives a centrifugal turntable 12 to rotate, and a plurality of containers are hung around the centrifugal turntable 12 . 13. The container 13 is filled with the mixed liquid 14 to be treated, and the centrifugal force generated by the centrifugal turntable 12 is operated by the motor 11, and the mixed liquid 14 in the container 13 is separated from the upper light liquid 141 and the lower heavy liquid 142. This operation mode can be produced in batches. The disadvantage is that continuous continuous separation of heavy liquid and light liquid cannot be achieved.

As shown in Fig. 2, it is a schematic diagram of a conventional disc continuous centrifuge. The machine includes a trough 20. A motor 21 is used to drive the centrifugal disc 22 in the housing 20 to rotate. A mixed liquid delivery pipe 23 communicates with the bottom of the tank body 20 for continuously supplying the mixed liquid 28 in the tank. A heavy liquid overflow pipe 24 is connected to the upper outer wall of the tank body 20. A light liquid overflow pipe 25 whose overflow port 251 is located in the vicinity of the axial center 211 of the motor 21 in the tank body 20. When the disc continuous centrifuge is operated, the mixed liquid 28 is continuously fed into the tank from the bottom of the tank body 20 by the mixed liquid delivery pipe 23, and the motor 21 drives the centrifugal disc 22 to rotate, and the centrifugal force generated by the swirling water flow in the tank makes the liquid in the tank Divided into three layers. The uppermost layer near the inner wall is the distribution area of the heavy liquid 281, and the center near the axis 211 is the light liquid 282 distribution area, which is divided upward by the lower layer. Between the heavy liquid 281 and the light liquid 282, it is a mixed liquid 28 stock solution. The heavy liquid 281 can be collected by flowing out of the heavy liquid overflow pipe 24, and the light liquid 282 is collected by the light liquid overflow pipe 25 to be collected. Although this machine can perform continuous separation, it is only suitable for the use of two liquids with large differences in specific gravity, such as oil-water separation. If the difference in specific gravity is small, it is easy to mix or the separation is incomplete.

The main purpose of this creation is to provide a continuous centrifuge that can be used for the separation of mixed liquids with similar specific gravity, and can automatically separate and produce heavy liquid and light liquid continuously.

For the above purposes, the creation includes a centrifugation tank, a liquid supply tank matched with the pipeline, a centrifugal water flow pump, a light liquid collection tank, and a heavy liquid collection tank. The centrifugal tank comprises a light liquid suspension tank, an accelerating centrifugal tank, and a heavy liquid settling tank, wherein the troughs are connected in series from top to bottom, wherein the inner diameter of the accelerating centrifugal trough is gradually decreasing from top to bottom; The liquid supply tank has a liquid supply pipe communicating with the centrifugal tank to supply the mixed liquid into the centrifugal tank; the centrifugal water flow pump has two circulating pipes connected to the accelerated centrifugal tank to generate a swirling water flow in the tank; The light liquid collection tank has at least one light liquid overflow pipe connected to the light liquid suspension tank; and the heavy liquid collection tank has at least one heavy liquid overflow pipe connected to the heavy liquid sink tank.

The creation is to use the water flow pump to generate a vortex water flow in a cone-shaped accelerating centrifugal tank, and the downward centrifugal force generated can increase the separation gravity and accelerate the separation effect, so that the light liquid in the mixed liquid gathers upward at the swirl center. The heavy liquid converges on the periphery of the vortex to settle down, and then is collected and collected by the light liquid overflow pipe and the heavy liquid overflow pipe at the corresponding positions. Therefore, the design of the present invention can effectively separate two liquids with similar specific gravity, and can be continuously separated and produced with high quality and high efficiency.
