Description

Technical Field

[0001] The utility model relates to a cyclone adjustable inner diameter sand settling nozzle. Background Technique

[0002] A cyclone is a common separation and classification device, and its working principle is centrifugal sedimentation. The basic principle of a cyclone is to separate a two-phase mixture such as liquid-liquid, liquid-solid, and liquid-gas with a certain density difference under the action of centrifugal force. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery at a certain pressure, different centrifugal forces will be generated and the two phases will be separated.

[0003] The cyclone sand settling nozzle is a key component in the cyclone device. Its main function is to separate solid particles and liquid in the solid-liquid mixture, so that the particles settle to the lower part and are discharged through a pipeline, thereby ensuring that the liquid flowing out of the outlet pipe is clean. The cyclone sand settling nozzle is usually made of wear-resistant materials such as polyurethane and ceramic silicon carbide to adapt to the harsh working environment and improve the service life. The design of the sand settling nozzle needs to consider the flow characteristics of the fluid and the separation effect of solid particles to ensure the best separation effect. Its internal structure design and the size of the inner diameter of the sand settling nozzle have a certain impact on the pressure of the cyclone.

[0004] There is a certain relationship between the inner diameter size of the cyclone sand settling nozzle and the pressure inside the cyclone. At present, the diameter of the sand settling nozzle of the knob device is fixed. When processing different particle mixed liquids or different pressure flow rates, it will cause different sedimentation speeds of the sand settling nozzle particles, which is likely to cause the liquid in the outlet pipe to be turbid and is not easy to effectively control.

An adjusting head is fixedly connected to the top of the movable rod.
