Description

Cyclone separator {Cyclone separator}

The present invention relates to a cyclone separator, and more particularly, to a cyclone separator capable of preventing an outlet from being clogged with separated particles.

A cyclone separator is a device capable of separating particles contained in a fluid using centrifugal force. Cyclone separators are widely used because they can continuously and stably separate foreign substances from a large amount of fluid.

At this time, a cyclone separator using water as a fluid is called a hydro cyclone separator, and the hydro cyclone separator is also used to dehydrate a mixture.

Looking at the driving principle of the hydrocyclone separator, a mixture of fluid and particles is injected into the hydrocyclone separator, and the injected mixture rotates inside the hydrocyclone separator. At this time, particles having a relatively large particle size descend downward, while water or small substances rise upward by centrifugal force, and the fluid and particles may be separated.

On the other hand, in order for the hydrocyclone separator to function properly, an air-core must be formed. In the process of discharging large-sized materials, such as slurry, to the lower side of the hydrocyclone separator, the outlet of the hydrocyclone separator There is a blockage problem.

In addition, foreign substances such as slurry are discharged at high pressure in the form of a spray from an outlet formed in the hydrocyclone separator, but in this case, there is a problem in that the outlet is rapidly worn.

An inlet formed on the upper portion of the housing, a first discharge port formed on the upper portion of the housing and formed toward the outside of the housing from the separating portion, and a second discharge port formed on the lower portion of the housing and formed toward the outside of the housing from the separating portion. and a separation tube disposed at the center of the second outlet and extended to have a length.

In addition, at least a portion of the separator may be formed in a shape in which a diameter decreases as it goes downward.

In addition, the first outlet and the second outlet may be formed parallel to each other.

In addition, the separation pipe may be formed to extend from the second outlet to at least a part of the separation unit.

In addition, a separation space may be provided between the separation pipe and the inner wall of the second outlet.

Hereinafter, a cyclone separator according to the present invention based on the above-described principle will be described in detail with reference to the drawings.

The cyclone separator 10 according to the present invention may be used to separate target particles OJ from a mixture. Here, the target particle OJ may mean a particle to be separated from the mixture using the cyclone separator 10 .

For example, the fluid may be water. Also, the target particle OJ may be gypsum. That is, the mixture may be a mixture of particles such as gypsum in a fluid such as water. As such, when the fluid is water and the target particle OJ is gypsum, the cyclone separator 10 may perform a function of dewatering the gypsum.

However, it is not limited thereto, and the fluid may be a fluid other than water, the target particle (OJ) may be a material other than gypsum, and if the particles included in the fluid can be separated by the difference in particle size, the present invention The cyclone separator 10 according to the invention may be a mixture to be separated.

1 is a perspective view schematically illustrating a cyclone separator 10 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line XX′ of FIG. 1 .

Referring to FIGS. 1 and 2 , the cyclone separator 10 may include a housing 110 .

The housing 110 may form the overall appearance of the cyclone separator 10.

A separator 111 for separating the mixture may be provided inside the housing 110 . The separation unit 111 is a space provided inside the housing 110, and the mixture flowing into the separation unit 111 can rotate inside the separation unit 111, and the fluid and target particles (OJ) can be separated by centrifugal force.

An inner surface portion 112 may be disposed inside the housing 110 . The inner surface portion 112 may refer to an inner surface of the housing 110 and may include at least a portion of the inner surface of the housing 110 to form the separating portion 111 .

The inner surface portion 112 may form the separating portion 111 . As will be described later, an inlet 121 may be formed on the inner side portion 112, and the mixture is introduced through the inlet portion 121, and then the inside of the separator 111 defined by the inner side portion 112. It can be separated while rotating in.

The cyclone separator 10 may include an inlet 120 .

The inlet 120 may guide a path through which the mixture flows into the separator 111 .

The inlet 120 may be formed on the side of the housing 110 . The housing 110 may communicate the separation part 111 and the outside of the housing 110 to each other. For example, the inlet 120 may include a hollow formed therein in the longitudinal direction so that the outside of the housing 110 and the separator 111 communicate with each other.

As an example, the inlet 120 may include an inlet 121 formed on the inner surface portion 112 of the separator 111 . The inlet 121 is a through hole formed in the inner surface portion 112 of the separation unit 111 and may be a portion through which the mixture passing through the inlet 120 flows into the separation unit 111 .

The mixture may be introduced into the separator 111 while being pressurized through the inlet 120 . Since the mixture under pressure is introduced into the separation unit 111 through the inlet 121, the mixture can rotate inside the separation unit 111 by inertia.

Here, the pressure applied to the mixture may be the pressure of a separately provided pump pushing the mixture into the inlet 120 . In addition, the pressure applied to the mixture may be pressure applied by a separately provided device to rotate the mixture already introduced into the separator 111 .

As an example, the inlet 120 may be formed on an upper part of the inner surface of the separator 111 . Therefore, while the mixture introduced into the separation unit 111 continuously rotates, the target particles OJ can gradually move to the lower side of the separation unit 111, and as a result, the mixture can be continuously and efficiently separated.

As an example, at least a portion of the separation unit 111 may be formed in a shape in which a diameter decreases as it goes downward. For example, the separation unit 111 may be formed in the shape of an inverted cone.

Therefore, the mixture introduced into the upper portion of the separator 111 through the inlet 121 may continuously rotate. In addition, the separated target particle OJ may gradually move below the separator 111 by gravity, and since the diameter of the lower part is small, the concentration of the target particle OJ may increase downward.

Specifically, a lower separator 113 may be disposed below the separator 111 . The lower separating part 113 may mean a part of the lower side of the separating part 111 .

As described above, while the mixture is continuously rotated after being introduced into the separation unit 111, the target particles OJ separated from the mixture gradually move downward, and the target particles OJ in the lower separation unit 113 concentration can be increased. The target particles (OJ) collected in the lower separator 113 may then be discharged to the outside of the separator 111 .

The cyclone separator 10 according to the present invention may include a first outlet 130 and a second outlet 140 disposed in the housing 110 .

The first outlet 130 may be formed on the top of the housing 110 .

The first outlet 130 may guide a path through which the fluid separated from the separator 111 is discharged to the outside. To this end, one end of the first outlet 130 may be connected to the separation unit 111 and the other end of the first outlet 130 may be connected to the outside of the housing 110 . In addition, one end and the other end of the first outlet 130 may communicate with each other.

The second outlet 140 may be formed in the lower part of the housing 110 .

The second outlet 140 may guide a path through which the target particles OJ separated from the separator 111 are discharged to the outside. To this end, one end of the second outlet 140 may be connected to the separation unit 111 and the other end of the second outlet 140 may be connected to the outside of the housing 110 . Also, one end and the other end of the second outlet 140 may be in communication with each other.

As an optional embodiment, the first outlet 130 and the second outlet 140 may be disposed parallel to each other. That is, the first outlet 130 and the second outlet 140 are provided on the upper and lower portions of the housing 110, respectively, and an imaginary line connecting the first outlet 130 and the second outlet 140 is a straight line. can achieve Of course, the first outlet 130 and the second outlet 140 are not connected to each other.

Accordingly, while the mixture rotates in the separation unit 111, the target particles OJ and the fluid have flows in opposite directions, so that they can be efficiently separated.

That is, if the first discharge port 130 and the second discharge port 140 are not parallel to each other, the flow of the target particles OJ and the fluid do not flow in completely opposite directions, causing a problem of mixing again inside the separator 111. can

Hereinafter, a process in which the mixture is separated in the separator 111 will be described in detail.

The cyclone separator 10 according to the present invention can separate the mixture by the difference in particle size.

Specifically, in the process of rotation after the mixture is introduced into the separation unit 111, the target particles (OJ) having a particle size of a certain size or more gradually descend to the lower side of the separation unit 111 by gravity to the lower side of the separation unit 111. It can be gathered in the separation part 113. The target particles OJ collected in the lower separator 113 may be discharged through the second outlet 140 .

The target particles (OJ) collected in the lower separator 113 are sprayed from the end of the second outlet 140 due to the inertia rotating in the separator 111 and the continuously flowing target particles (OJ). It can be. That is, the target particles OJ collected in the lower separator 113 may be radially sprayed from the end of the second outlet 140 while rotating with strong pressure.

In addition, in the process of rotation after the mixture is introduced into the separation unit 111 , particles having a particle size of a certain size or less may be discharged through the first discharge port 130 while rotating while being mixed with the fluid. At this time, an air core (AC) may be formed in the separator 111 . The air core AC is a vortex generated as the mixture rotates in the separation unit 111, and may have a path discharged from the inside of the separation unit 111 through the first outlet 130 to the outside.

As such, the reference particle size for determining the target particle OJ to be separated from the inside of the separator 111 through the second outlet 140 is referred to as a cut particle size. That is, while the mixture rotates inside the separator 111, the target particles (OJ) larger than the cutting particle diameter are sprayed through the second outlet 140, and the particles smaller than the cutting particle diameter are sprayed through the air core (AC) with the fluid. It can be discharged through the first discharge port 130.

FIG. 3 is a cross-sectional view of a cyclone separator 10 according to another embodiment of the present invention taken along the line XX′ of FIG. 1, and FIG. 4 is a view for explaining the operation of the cyclone separator 10 of FIG. am. 5 is a cross-sectional view taken along line Y-Y′ of FIG. 3, and FIG. 6 is an enlarged view of part Z of FIG.

Referring to FIGS. 3 to 6 , the cyclone separator 10 according to another embodiment of the present invention may include a separation pipe 150 .

Separation pipe 150 may be disposed in the second outlet 140 and extended to have a length.

As an example, the separation pipe 150 may be disposed parallel to the second discharge port 140 and may be disposed at the center of the second discharge port 140 .

The separation pipe 150 can solve the problem that the air core AC is not formed due to the second outlet 140 being blocked.

Specifically, in order to continuously separate the mixture, the air core (AC) must be continuously formed. However, when the target particles (OJ) are continuously accumulated in the lower separator 113 inside the separator 111, the concentration of the target particles (OJ) gradually increases, and then the target particles (OJ) eventually become sludge and form the second A problem of blocking the outlet 140 may occur. Therefore, when the second outlet 140 is clogged, the cyclone separator 10 may not smoothly perform the function of separating the mixture, or the operation of the cyclone separator 10 may stop altogether.

Accordingly, the separation pipe 150 may be disposed at the center of the second outlet 140 to provide a separate path for forming the air core AC and a path for discharging the target particles OJ.

The separation pipe 150 may be formed in a tube or tube structure that is formed to have a length. As an example, the separation tube 150 may be disposed at the center of the second outlet 140 and extend from the second outlet 140 to at least a portion of the separation unit 111 . However, the separation pipe 150 may not be formed to extend to a portion corresponding to the first discharge port 130 .

Referring back to FIG. 4 , the concentration of the target particle OJ increases toward the lower side of the separator 111 while rotating in the separator 111 as described above. Therefore, since the concentration of the target particles OJ is not high on the upper side of the separation unit 111, the upper side or the center of the separation unit 111 is not blocked in the form of sludge. However, since the target particle OJ has a higher concentration in the lower part of the separator 111, that is, in the lower separator 113, the lower separator 113 or the second outlet 140 may be blocked.

Accordingly, the separation tube 150 may be formed to extend from the second outlet 140 to at least a portion of the separation unit 111, and as an example, to at least a portion of the lower separation unit 113 or to the lower separation unit ( 113) may be formed by extending to a length including.

In addition, when the separation tube 150 extends to the first discharge port 130, as will be described later, since the air core AC is not formed at the center of the separation tube 150, the separation tube 150 is the first discharge port ( 130) may not be extended.

As an example, the separation pipe 150 may be detachable. Therefore, when durability of the separation tube 150 is exhausted due to abrasion or corrosion, only the separation tube 150 may be replaced instead of replacing the entire cyclone separator 10 . Thereby, the maintenance cost of the cyclone separator 10 can be reduced.

As another example, the separation pipe 150 may be integrally formed with the housing 110 . For example, the separation tube 150 may be a part integrally formed inside the housing 110 to pass through the second outlet 140 . In this case, since the separation pipe 150 can be firmly fixed to the housing 110, durability can be increased.

As an example, a separation space may be provided between the separation pipe 150 and the inner wall of the second outlet 140 . As such, since the separation pipe 150 is disposed at the center of the second outlet 140 to be spaced apart from the inner wall of the second outlet 140, the second outlet 140 may be divided into at least two regions.

Specifically, the second outlet 140 may include a first area 151 formed in the center and a second area 152 formed along the circumference of the first area 151 .

The first region 151 may be inside the separation pipe 150 . The first region 151 may be a portion where the air core AC is formed. The first region 151 may be formed at the center of the separation tube 150 and, as an example, may have a circular cross section.

The second area 152 may be a path along which the target particle OJ moves. The second area 152 may be disposed to surround the first area 151 .

The first region 151 and the second region 152 may be physically separated.

The separation tube 150 may include a barrier rib, and the barrier rib may form the overall shape of the separation tube 150 . Accordingly, the first region 151 and the second region 152 may be physically separated from each other and partitioned by the barrier rib of the separation pipe 150 .

As an example, the separation pipe 150 may include at least one extension part 153 extending from the partition wall.

The extension part 153 may be formed to radially extend from the partition wall of the separation tube 150 in an outward direction around the circumference.

The separation pipe 150 may be disposed at the center of the second outlet 140 by the extension part 153 . For example, a plurality of extensions 153 may be formed, and a plurality of extensions 153 may be formed along the circumference of the separation pipe 150 . Also, the plurality of extension parts 153 may have the same length as each other. Therefore, when the separation pipe 150 is disposed inside the second discharge port 140, since the length of the extension part 153 is the same, the first region 151 may be disposed at the center of the second discharge port 140. .

Referring again to FIGS. 4 to 6 , the air core (AC) and the target particle (OJ) may be located in different regions by the separation pipe 150 . Specifically, the air core (AC) may be formed in the first region 151 disposed inside the separation pipe 150 and extend toward the first discharge port 130 . Therefore, the fluid and particles smaller than the cutting particle size may be discharged through the first discharge port 130 .

On the other hand, the target particles (OJ) larger than the cutting particle diameter may flow along the second area 152 and be sprayed at high pressure from the end of the second outlet 140 in the form of a spray.

In this way, since the target particle OJ flows through the second region 152 physically separated from the first region 151 where the air core AC is formed, the target particle OJ flows through the second discharge port 140 ) may be blocked to solve the problem that the air core AC is not formed.

That is, while the target particle OJ moves along the separator 111, the air core AC is formed independently from the first region 151 toward the first discharge port 130 regardless of the target particle OJ. It can be. Therefore, it is possible to solve the problem that the second outlet 140 is clogged by the target particles OJ, and thus the formation of the air core AC is hindered.

7 is a cross-sectional view of a cyclone separator 10 according to another embodiment of the present invention.

Hereinafter, for convenience of description, contents that are the same as those of the above-described embodiment or that can be easily changed by a person skilled in the art will be omitted or briefly described.

As described above, the target particles OJ may be sprayed at high pressure from the end of the second outlet 140 in the form of a spray. In this case, the end of the second outlet 140 may be worn out.

To this end, referring to FIG. 7 , the cyclone separator 10 according to another embodiment of the present invention may further include a skirt 160 formed at the lower end of the housing 110 .

The skirt 160 may be formed in the form of a wall extending to surround the bottom surface of the housing 110 . For example, the skirt 160 may be formed in a substantially cylindrical shape.

As shown in FIG. 7 , the skirt 160 may be formed to a size sufficient to cover a part of the lower surface of the second outlet 140 and the housing 110 .

The skirt 160 may reduce the spray intensity of the target particles OJ sprayed from the second outlet 140 . That is, the target particles OJ sprayed by the skirt 160 collide with the skirt 160 so that the spray intensity can be reduced.

Accordingly, the spraying intensity of the target particles OJ may be weakened by the skirt 160 and the degree of abrasion of the second outlet 140 may be reduced.
