The working principle of the three separation separator, the working principle of the three separati

Although the sprinkling of the three-separation separator is also realized by the rotation of the grading mechanism, it is different from the first and second generation separators: in principle, the sprinkling of the O-SEPA separator is completed by two parts of continuous operation process. The first process is to throw the powder onto the baffle plate by the upper sprinkler tray of the grading cage; The other process is to mix the thrown powder with gas powder by rotating air flow, and form a two-phase flow of gas powder through gas powder mixing.

The effects of both processes have a direct impact on the spreading effect of the O-Sepa separator. The first is the uniformity of the material curtain distributed along the circumference of the 360° powder thrown by the sprinkler tray, and the second is the adequacy and timeliness of the "gasification" process of the material curtain by the rotating air flow, which will affect the grading effect of the powder separator on the mixed powder. Sufficiency and timeliness are important here.

The structure that has an impact on the spreading effect: the number of feeding points, the position of the feeding point on the spreading tray, the structure of the spreading tray, the position of the baffle plate, the gap between the baffle plate and the spreading tray, the length of the baffle plate, the gap between the rotating cage and the guide vane, etc. The working parameters that affect the sprinkling effect are:

The rotation speed of the scattering pan, the amount of material processed, the gas flow, the radial and tangential velocity and velocity distribution of the rotating gas flow, etc.

1. Divide the material into three, that is, "coarse powder (d>150um) and medium coarse powder (60um).

2. The grading principle is advanced. Combined with a variety of powder selection principles, the material is selected through two powder selection areas, and the grading accuracy is higher and more accurate. 3. The spindle of the separator adopts stepless speed regulation. The fineness is easy to adjust, sensitive and reliable, and has a wide adjustment range.

4. The spatial scope of the powder selection area and the lifting area was re-optimized to improve the efficiency of powder selection.

5. For the vulnerable wear-resistant parts, a new type of manganese plate is used, which effectively prolongs its service life.

6. The new design scheme of the bearing seal under the spindle effectively solves the two major problems of bearing dust and lubricating oil leakage, and effectively prolongs the service life of the lower bearing.

7. When designing the separator and the foundation, the principle of mechanical vibration reduction is adopted, so that the resonance frequency between the separator and the foundation is not close to the natural frequency of the separator and the natural frequency of the foundation, which fundamentally solves the vibration problem of the separator that has plagued the manufacturer for a long time.

8. The coarse powder pipe, medium coarse powder pipe and fine powder pipe all adopt double interlocking dampers, which greatly reduces the air leakage rate of the system and overcomes the defect of large dust during the operation of the previous powder separator.

How it works. When the three-separation high-efficiency vortex separator works, the variable speed motor drives the spindle to rotate through the transmission device, the material enters the center of the powder separator through the feed port located at the upper part of the powder separator, and then falls to the bottom of the powder separator chamber through the special blanking pipe on the sprinkling tray that rotates with the spindle, the logistics is evenly sprinkled around under the action of the high-speed rotating sprinkling tray, and the high-speed throwing material is strongly dispersed under the action of the high-speed rotating air flow generated by the external circulating fan, and the coarse and heavy particles (d> in the material150 m) is thrown to the wall of the powder separator by the action of inertial centrifugal force, loses kinetic energy after collision and slides down the wall surface and falls into the coarse powder cone, and the rest of the material is blown up by the rotating air flow and continues to rise, and when passing through the large wind blade area, some coarse particles are separated and fall into the coarse powder cone.

The material (d<150 m) after two separations by the sprinkler tray and the large fan blade continues to rise into the grading zone: the plane vortex grading zone. Under the action of the strong and stable plane vortex formed by the rotating cage rotor, the dusty air flow makes the coarse powder that does not meet the requirements of the finished product be further accurately selected, because the inertial centrifugal force generated by the coarse particles is greater than the centripetal suction force of the vortex, the coarse particles are thrown to the surrounding vertical guide vanes, lose kinetic energy after impact, fall into the medium coarse powder cone, and be eliminated by the medium coarse powder airlock valve.

The fine powder (d<60mm) that meets the requirements passes through the cage and enters the inside of it, enters the separator arranged around the powder sorting chamber with the circulating air, and is collected to form the finished fine powder.

The difference between a rotor separator and a triple separator.

First, the similarities.

1. All of them use the cyclone as the finished product collection mode;

2. Extracorporeal circulation fans are used as the power source for aerodynamic classification;

Second, the differences.

1. The air volume distribution of the extracorporeal circulation fan is different: the rotor separator generally uses a medium-pressure centrifugal fan, while the three-separation separator uses a high-pressure centrifugal fan.

2. The grading rotor is different: the rotor separator adopts an inverted conical rotor, and its grading force field is unstable from top to bottom, while the cylindrical grading rotor used in the three-separation separator, coupled with the guide blades used in the periphery of the rotor, the grading force field is extremely stable, and the material is evenly stressed in the grading force field, so the grading accuracy of the three-separation separator is also superior.

3. The rotor separator does not use guide vanes. Guide vanes are used around the rotor of the three-separation separator.

4. The classification principle is different: the three-separation separator adopts the core principle of the third generation of high-efficiency classifier - the plane vortex classification principle, and the material of the separator using this principle is stable in the grading force field and has high grading efficiency. The rotor separator is different.

5. The number of cyclones is 4 high-efficiency and low-resistance cyclones to collect fine powder, which increases the vortex angle of the air inlet and prolongs the residence time of the dusty air flow in the cyclone, thereby improving the collection of fine powder at all levels.

6. Different sprinkling trays for sprinkling: the rotor separator takes the lower part of the sprinkling, and the air enters the lower tangential air intake, and passes through the conical cage to achieve classification in the process of air entry and rise, and the graded air flow takes the finished fine powder out of the powder selection room, and the dusty air flow discharged from the powder sorting room is then sent to the cyclone for gas powder separation to realize the collection of finished products. O-SEPA separator is to take the upper sprinkling, this sprinkling does not rely on the sprinkling tray, but through the sprinkling tray after the distribution of the material by the weight of the material for free fall, the plane tangential air intake, through the cylindrical cage to form a cylindrical vortex to achieve classification, the finished fine powder with the air flow out of the powder selection chamber into the dust collector to achieve fine powder collection.

The scattering tray of the rotor separator is a flat plate type, which relies on the radial centrifugal force and radial motion generated by rotation;

The spreading tray of the O-Sepa separator is of the auger type, which facilitates the removal of fine material when the air flow passes through, and it is clear that this spreading effect is better than that of flat spreading.

7. Fundamentally speaking: the rotor separator is improved on the basis of the second generation of cyclone separator, and the three-separation separator is improved on the basis of the third generation O-Sepa separator. Its core: dispersion, grading, separation.

8. The body shape of the three-separation separator with the same processing capacity is smaller than that of the rotor separator. Therefore, the material-gas ratio of these two separators is different, the material-gas ratio of the three-separation type is about 3, while the rotor type is 2.

In the working state, the high-speed motor drives the vertical transmission shaft to rotate through the transmission device, the material enters the powder sorting chamber through the feed port located at the upper part of the powder separator room, and then falls on the scattering tray through the upper and lower cones of the medium and coarse powder collection cone and the powder pipeline, the scattering tray rotates with the vertical transmission shaft, the material is evenly sprinkled around under the action of inertial centrifugal force, and the dispersed material enters the powder sorting chamber through the air inlet of the external fan under the action of high-speed airflow. The coarse and heavy particles in the material are thrown against the inner wall of the sorting chamber by the action of inertial centrifugal force. After the collision, the loss of kinetic energy slides down the wall surface, falls into the coarse powder cone, and the rest of the particles are rolled up by the rotating rising airflow, when passing through the action zone of the large wind blade, under the impact of the large wind blade, a part of the coarse powder particles are thrown to the inner wall surface of the powder sorting chamber, and the loss of kinetic energy slides down the wall surface after the collision and falls into the coarse powder collection cone.

After the medium coarse powder and fine powder pass through the large wind blade, under the action of the updraft, they continue to rise through the vertical guide blade and enter the secondary powder separation area. Under the action of the strong and stable plane vortex formed by the rotating cage rotor, the dust-containing air flow causes the medium coarse powder to be thrown to the vertical guide vane under the action of centrifugal force, loses kinetic energy, falls into the medium coarse powder collection cone, and is discharged through the medium coarse powder tube. The fines that meet the requirements pass through the cage rotor and enter the interior of the cage rotor, enter the high-efficiency and low-resistance cyclone separator with the circulating air, and then slide down into the fine powder collection cone to become the finished product.

Compared with the traditional separator, the three-separation high-efficiency separator has the following outstanding advantages:

1. Good performance and high efficiency. The three-separation separator divides the material into three, that is, "coarse powder (d>150um) and medium coarse powder (60um<>

"The coarse powder is returned to a warehouse, and the medium coarse powder is sent to the grinding bin of the mill through a high-speed reamer (it can also enter a bin with the coarse powder), and the fine powder is directly transported to the warehouse.

2. Compared with centrifugal, cyclone and rotor separators with similar sizes, SEPAX high-efficiency three-separation separators have much higher output, so they are more suitable for the needs of large-scale production. The advanced and reasonable structure allows the air volume, output and feeding volume of powder separation to change in a large range without affecting the efficiency of powder separation, and its grading performance is very stable.

3. The classification principle of high-efficiency three-separation separator is advanced. Combined with a variety of powder separation principles, the aerodynamic analysis method was used to optimize the design of the entire flow field, so that the equipment resistance was significantly reduced and the powder separation efficiency was higher. Energy saving and consumption reduction are very obvious.

The rotor of the separator is equipped with a vortex rectifier that has obtained a national patent, and the air flow in the rotor only rises and does not rotate relative to the rotor, and the internal momentum torque of the air flow into the rotor is used to reduce the driving force of the rotor, saving driving power and reducing wear. The material is selected by two powder selection areas, and the grading accuracy is higher and more accurate.

4. The spindle of the high-efficiency three-separation separator adopts stepless high speed. The fineness is easy to adjust, sensitive and reliable, and has a wide adjustment range.

5. The high-efficiency three-separation separator re-optimizes the spatial scope of the powder separation area and the lifting area, makes full use of the main space to increase the material-gas ratio and improves the powder separation efficiency.

The vulnerable wear-resistant parts of the high-efficiency three-separation separator, such as the sprinkler tray, cyclone tube, snail horn, wind guide blade and rotor, are made of wear-resistant materials or treated with anti-wear technology, and the wear rate is extremely low. The use of new manganese plate effectively prolongs its service life.

7. The new design scheme of the bearing seal under the spindle of the high-efficiency three-separation separator adopts a new design scheme, which effectively solves the two major problems of bearing dust and lubricating oil leakage, and effectively prolongs the service life of the lower bearing.

8. When designing the foundation of the high-efficiency three-separation separator, the principle of mechanical vibration reduction is adopted, so that the resonance frequency between the separator and the foundation is not close to the natural frequency of the separator, which fundamentally solves the vibration problem of the separator that has plagued the manufacturer for a long time.

9. The coarse powder pipe, medium coarse powder pipe and fine powder pipe of the high-efficiency three-separation separator all adopt double interlocking dampers, which greatly reduces the air leakage rate of the system and overcomes the defect of large dust during the operation of the previous powder separator.
