Adjustable Parameters of The Hydrocyclone Separator

The hydrocyclone separator is an effective device for separating the fluid between the two compartments by using the centrifugal force field. The classification efficiency of the cyclone is influenced by parameters. Among them, the adjustable parameters include the diameter of the cyclone, the diameter of the overflow pipe, the insertion depth of the overflow pipe, and the diameter of the sand settling port.

1. Change the cyclone diameter

Other parameters remain unchanged, the processing capacity is proportional to the diameter of the cyclone, and the diameter of the overflow pipe is also proportional to the diameter of the cyclone. Therefore, the diameter of the cyclone is increased by 2 times, and the processing capacity is increased by 4 times.

2. Change the diameter of the overflow pipe

The diameter of the overflow pipe has a great influence on the entire cyclone. The larger the diameter of the overflow pipe, the lower the pressure, the higher the overflow yield, and the thicker the overflow fineness. The classification efficiency tends to be stable at first and then decreases, so the classification efficiency should be maintained within the stable range. The influence of the diameter of the sand settling port on the entire cyclone is relatively small. However, the larger the sedimentation mouth is, the greater the amount of sedimentation will be, and the content of fine particles will also increase. Therefore, if the overflow port and the sedimentation port are adjusted at the same time, the relative productivity of overflow and sedimentation can be changed.

The diameter of the cyclone overflow pipe also has a great influence on the pyramid ratio of the hydrocyclone. Pyramid ratio refers to the ratio of the diameter of the overflow pipe to the diameter of the sedimentation mouth, which is an important parameter that affects the volumetric yield of overflow and sedimentation and the classification particle size. In actual production, the pyramid ratio of the cyclone used is generally 3~4. Generally, a smaller pyramid ratio can be used for the classification of fine-grained materials, while a larger pyramid ratio can be used for the classification of coarse-grained materials.

3. Change the wall thickness and insertion depth of the overflow tube

The wall thickness of the overflow pipe also affects the overflow effect. The experimental results show that increasing the wall thickness can also increase the separation efficiency, reduce the internal energy loss, and improve the production capacity.

In addition, the depth of the overflow tube insertion will also have an impact on the diversion effect. It is because the change of the insertion depth will affect both the pressure drop and the separation effect. The deeper the insertion, the pressure drop first increases and then decreases. However, if the insertion is too deep, the large particles cannot be separated smoothly.
