Today, the hydrocyclone manufacturer introduces you to the structure and working principle of hydrocyclones. Hydrocyclones are generally used for mineral grading, sorting, concentration, desliming and oil-water separation, etc. They are based on the density difference between materials. Sorting equipment. The following is a better understanding of the hydrocyclone through the internal structure of the hydrocyclone.
The working principle of the hydrocyclone: the slurry enters the shell along the tangential direction of the column through the feeding pipe under pressure, and makes a rotary motion in the shell. The coarse particles (or dense particles) in the slurry are greatly affected by Centrifugal force enters the periphery of the revolving flow, and flows downward with the slurry flow, and is finally discharged from the grit nozzle at the bottom to become sediment; the centrifugal force of the fine particles is small, and they are in the center of the revolving flow and move up with the liquid flow, and finally by the overflow The pipe discharge becomes overflow.
The internal structure of the hydrocyclone is divided into a feed port, responsible for the entry of materials; a cylindrical outer shell; an overflow pipe, conveying low-density materials; a cone-shaped container; a discharge port, the discharge of coarse and heavy particles; a conduit, the discharge of fine particles . In addition, the hydrocyclone has a feed pipe, an overflow pipe, an overflow pipe and a grit port. The main body part is a hollow cylinder at the upper end and an inverted cone communicating with the cylinder at the lower part, and the two are connected by an overflow pipe.
The following cyclone manufacturers better explain the role of each part of the internal structure of the hydrocyclone through the working principle of the hydrocyclone: ??the material enters the cylindrical part from the inlet at a certain pressure in the tangential direction, and the material moves along the inner wall of the cylinder. , Under the combined action of centrifugal force and gravity, the denser materials move downwards spirally along the inner wall of the cylinder, and are finally discharged from the bottom discharge port. The less dense materials spiral upwards through the separation interface along the central part. , And finally discharged by the overflow pipe and the finer ore particles form an inner spiral upward ore slurry flow with water in the center of the cone and discharged through the duct. The structural parameters that affect its effect during its work include hydrocyclone diameter, feed pipe diameter, feeding density, feeding method, overflow pipe diameter, cone angle, overflow pipe insertion depth, and feed Different structural parameters such as pressure, installation method, diameter of underflow orifice, etc. have different effects.
The upper part of the hydrocyclone is a hollow cylinder, and the lower part is an inverted cone communicating with the cylinder. The two form the working simplified part of the hydrocyclone. The upper end of the cylindrical cylinder is equipped with a feed pipe tangentially, and the top is equipped with an overflow pipe and an overflow conduit. There is a grit sink at the bottom of the conical cylinder. The parts are connected by flanges and screws. The mine mouth, barrel and grit mouth are usually lined with rubber, polyurethane, silicon carbide or diabase cast stone to reduce wear and replace them after wear.
The leading products of Chaishang Trading Co., Ltd. are cyclones and hydrocyclones, which are divided into: hydraulic classification cyclones for mines, heavy medium separation cyclones for coal, concentration and classification cyclones for chemical power plants, etc. . The material of the cyclone is made of high-quality wear-resistant polyurethane elastomer, wear-resistant rubber, high-aluminum ceramics, etc.
