Description

Cyclone

The present invention relates to a cyclone, and more particularly, to provide a cyclone that maximizes the separation efficiency by allowing the solid particles in the fluid to be separated more efficiently in the first and second order.

Cyclone is a representative of the dust collector is a separation device using the centrifugal force generated by the swirl flow of the fluid (fluid).

The cyclone separates solid particles suspended in gas (various fine grain particles, dust, etc.) or fine droplets, and is used as a separator in various fields for industrial purposes.

In the conventional cyclone, as shown in FIG. 1, when the fluid flows into the inlet pipe 6 connected to one side of the upper cylindrical part 2 of the cyclone 1, the fluid is caused by the centrifugal force generated by the swirl flow. ), While moving to the lower cone portion 3 while turning, solid particles in the fluid are collected by dropping into the discharge pipe 4, and the gas is inverted at the lower end of the cone portion 3 and turns upward to the outlet 5 of the upper portion. Configured to be discharged.

However, this cyclone (1) is a problem that when the fluid rises from the conical portion (3) to the cylindrical portion (2) is exhausted with a portion of the solid particles without falling into the discharge pipe (4) and the solid particles and discharged with the fluid Was stuck to the inner wall of the cyclone 1, and the collection efficiency was deteriorated.

Therefore, the present invention is to provide a cyclone to eliminate the problem that the efficiency is reduced when collecting the solid particles of the existing cyclone as described above.

Accordingly, the present invention is to provide a cyclone having the following means to achieve the above problems.

That is, the present invention is provided with a cylindrical tube through which the fluid rising and turning inverted in the cone portion outside the outlet formed in the upper portion of the cylindrical portion of the cyclone, and several fluid discharge in the tangential direction on the upper portion of the cylindrical tube A ball is formed, and a guide plate for guiding the fluid passing through the fluid discharge hole in the rotational direction is characterized in that formed on the outside of the fluid discharge hole.

Cyclone of the present invention is a circular circle installed between the cylinder and the outlet so as to separate and collect again the solid particles contained in the turning fluid inverted and rising in the cone after turning down the fluid flowing into the inlet pipe in the cylinder portion The solid particles in the fluid can be collected more reliably in the clearance to maximize the separation efficiency, and the expected effect is very useful, such as preventing the solid particles from adhering to the cyclone inner wall.

Figure 2 is a cross-sectional view showing a preferred embodiment of the cyclone provided by the present invention
3 is a cross-sectional view taken along line AA of the cyclone provided by the present invention.

Hereinafter, a detailed embodiment of a cyclone (1) for achieving the technical problem to be solved by the present invention will be described in detail with the accompanying drawings as follows. However, in the following description of the present invention, a configuration overlapping with the reference numeral described in the background art will be described using the same reference numeral.

Figure 2 is a cross-sectional view showing a preferred embodiment of the cyclone (1) provided by the present invention, Figure 3 is a cross-sectional view showing the main portion, a cylindrical portion (2) is formed on the upper portion, the lower portion of the cylindrical portion (2) Cone part (3) is formed in succession, a solid particle discharge pipe (4) is formed below the cone (3), the upper cylinder part (2) is formed with an outlet (5) to discharge the fluid is discharged, In the conventional cyclone (1) in which the fluid inlet pipe (6) is formed in the tangential direction on one side of the cylindrical portion (2),

A cylindrical tube 7 is installed outside the outlet 5 formed in the upper portion of the cylindrical portion 2 through which the fluid rising by turning inverted in the cone portion 3 can pass.

The diameter of the cylindrical tube (7) is larger than the diameter of the outlet (5), the diameter is made smaller than the diameter of the cylindrical portion (2), the height of the cylindrical tube (7) is made smaller than the height of the cylindrical portion (2) .

The upper portion of the cylindrical tube 7 is formed with a plurality of fluid discharge holes (8 in the tangential direction is illustrated in the case where four are formed) in the tangential direction, the fluid passing through the fluid discharge hole (8) A guide plate 9 for guiding in the pivoting direction is provided in the tangential direction outside the fluid discharge hole 8.

Cyclone (1) of the present invention can be configured as described above can be used to separate the solid particles and the like suspended in various fluids,

When the fluid containing solid particles flows through the inlet pipe 6 tangentially connected to one side of the cylindrical portion 2 of the cyclone 1, the centrifugal force is generated by the swirling flow inside the cylindrical portion 2 and the fluid rotates. While falling down to the lower cone (3), the solid particles in the cone (3) is collected by dropping through the discharge pipe (4).

Then, the fluid inverts in the lower portion of the conical portion 3 and turns upward while rising toward the outlet 5 at the upper portion. At this time, the rising fluid flows up into the cylindrical tube 7 while being formed in the cylindrical tube 7. Through the fluid discharge hole (8) it is again lowered to the lower portion of the cylindrical portion (2) to lower the residual solid particles contained in the fluid that has risen from the cone (3) back to the cone (3) to the discharge pipe (4) Drop collection.

As a result, the cyclone 1 of the present invention pivots down the fluid introduced into the inlet pipe 6 in the cylindrical section 2, and then separates the solid particles contained in the swirling fluid inverted upwardly from the cone section 3 again. In order to be able to collect the secondary particles to be lowered in the cylindrical tube (7) it is possible to collect solid particles in the fluid more reliably.

Although one of the preferred embodiments of the present invention has been described as described above, various modifications are possible without departing from the scope of the present invention. Therefore, the protection scope of the present invention should not be limited to the described embodiments, but should be defined by equivalents as well as the following claims.
