Product introduction

Product introduction

Polyurethane cyclone It is a cyclone made of polyurethane elastomer. It has the characteristics of high wear resistance, high strength, light weight and long service life.

preparation

1. Before the hydrocyclone is compounded, we should grind the cyclone equipment waiting for compounding to remove some impurities such as sand, stone, dust and other impurities on the surface of the equipment.

2. Before the compound operation of hydrocyclone, it is necessary to prepare the tools, such as clamps, iron frames, etc., or to ensure that the hydrocyclone equipment is smooth before starting the operation.

3. In the selection of hydrocyclone equipment adhesive can choose to use resin composite adhesive, this adhesive is currently used more, it has a higher degree of adhesion and environmental protection, more suitable for use as a swirl adhesive.

 Polyurethane cyclone

working principle

As a typical equipment of centrifugal force and gravity compound force field, it is widely used in many fields because of its simple structure, small floor area, convenient installation and operation, low operation cost.

The basic principle of hydrocyclone is to separate the liquid-liquid, liquid-solid, liquid-gas mixture with certain density difference under the action of centrifugal force. The mixture enters the hydrocyclone tangentially with a certain pressure, and produces a high-speed rotating flow field in the cylindrical cavity. Under the action of the swirling field, the components with high density in the mixture simultaneously move downward along the axial direction and outward along the radial direction. When they reach the cone section, they move downward along the wall of the separator and are discharged from the underflow port. Thus, the components with low density move towards the central axis and form an upward internal vortex in the center of the axis, and then discharge through the overflow port The purpose of two-phase separation is achieved.

Influencing factors of Hydrocyclone

(1) Structure parameters of Hydrocyclone

① The diameter productivity and overflow particle size of hydrocyclones increase with the increase of its diameter. Generally, the efficiency of large diameter hydrocyclones is poor and the content of coarse particles in overflow is large.

② The size and shape of the feed mouth become larger, the size of the feed mouth increases, the processing capacity increases, the overflow particle size becomes coarse, and the classification efficiency decreases.

③ When the diameter and insertion depth of overflow pipe increase, the size of overflow pipe increases, the processing capacity increases, the overflow particle size becomes coarse, and the classification efficiency decreases.

④ The diameter of the sand settling nozzle is large, the overflow flow is small, and the overflow particle size becomes smaller. It has the advantages of small settling mouth, high concentration, large overflow and high content of coarse particles.

⑤ The height of the column affects the duration of the centrifugal force acting on the pulp. Generally, the height of the column is 0.6 ~ 1.0 times of the diameter.

⑥ The cone angle of hydrocyclone mainly affects the separation particle size, the larger the cone angle, the easier the coarse particles to mix into the overflow; the smaller the cone angle, the smaller the overflow particle size.

(2) Operating parameters of Hydrocyclone

① The feeding pressure mainly affects the treatment capacity and grading granularity. With the increase of feed pressure, the classification effect can be improved and the grit concentration can be increased.

② Feed properties feed concentration and particle size composition directly affect the product concentration and particle size. The finer the grading particle size, the lower the feed concentration.

③ The best working mode of the sand settler is that the sand is discharged in the form of overflow and umbrella. The angle of the umbrella surface should not be too large, and the rigid energy should be dispersed. When it is used for concentration, the grit is discharged in the form of rope, and the concentration is high; when used for dehydration, the grit is discharged in a large umbrella shape, and the overflow has less solid content.
