As shown in FIGS. 1 to 6, the non-powered dust collecting apparatus 1, which is a feature of the present invention, can be realized by introducing the flow direction of air by blowing air generated from the outside or the silo for storing grain. do.

The first guide vane 110 and the second guide vane 110 are connected to the silo and are arranged radially and are rotated in the circumferential direction. 10) and a through hole (120) communicating with the first guide vane (10); an inlet portion (100) which is fixedly connected to the upper portion of the inlet portion and distributes the movement path of the introduced air through the first guide vane to the edge region An induction part 200 including a conical tube 210 for concentrating air and a rounded second induction vane 220 mounted at a predetermined gradient from the outer surface of the conical tube to accelerate the rotational force of the compressed air; And is capable of moving the dust particles by gravity toward the central portion to the edge region due to the rotation of the driven air which is advanced in the course of passing through the second guide vanes A discharge hole 410 formed in a spiral inner space and fixed above the centrifugal separator, for discharging purified air vertically rising vertically to the center by a centrifugal separator, A spiral space part 450 for guiding the rotational force to flow along with the inflow of dust vertically rising while turning along the edge area by the centrifugal separation part, a spiral space part 450 mounted in the reverse direction of the second guiding fringe through a peripheral area of the discharge hole, An inverse cyclone part 400 including a third guide vane 430 for inducing the inflow of dust into the spiral space due to the resistance of the flow due to the vortex phenomenon as the rotational force of the moving dust is lost, The dust which is directly connected to the end of the cyclone and has a conical shape with a vertical light-tight cone shape is discharged vertically downward, and the residual dust is transferred to the entrance portion, And a remaining cyclone part 500 directly connected to the connection pipe 10 at the upper end so as to pass through the process.

The entrance portion 100 is a component for sucking the airflow provided from the silo at the bottom portion, and includes a first guide vest.

The compressed air containing a large amount of foreign matter, dust, and the like discharged through the silo tuyeres (not shown) is guided to the cylindrical inlet portion 100, and the compressed air guided to the inlet portion passes through the first guide vanes 110 And is converted into a flow having a rotational force in the circumferential direction.

The through hole 120 is a coupling part of a connection pipe to be described later, and is an element for realizing recycling for more precise and accurate dust collection.

The induction unit 200 is a component that performs dust collection by centrifugal separation while artificially inducing the movement of the compressed air.

The conical tube 210 induces a flow of air to the edge region of the space while rubbing against the compressed air provided from the entrance 100. At this time, the rotational force is further accelerated while passing through the second guide vane 220 .

The centrifugal separator 300 is preferably provided in a cylindrical shape as a substantial section for collecting dust air. In other words, light dust and clean air move to the center of the cylinder due to the movement of the dust air which is rotated while rising along the inner edge of the cylinder, while foreign matter, dust, etc. having relatively heavy particles move along the inner wall of the cylinder And eventually enters the reverse cyclone section.

The centrifugal separator 300 can be fastened to the guide portion 200 in a flange type, and the construction of the guide portion and the entrance portion 100 is also the same.

The inverse cyclone unit 400 is provided to further maximize the dust collecting efficiency while decelerating the rotational force of foreign matter, dust or the like flowing from the centrifugal separator 300.

The inverse cyclone unit 400 is a major part of the present invention, and will be described in detail below.

The remaining cyclone part 500 is provided for discharging foreign matter such as dust and the like which has lost the rotational force while passing through the area of the inverse cyclone part 400.

At this time, the fine dust which has not been discharged to the remaining cyclone part is re-introduced to the entrance part 100 through the predetermined connection pipe 10 to perform the re-separation process.

In addition, the air which has been moved upward to the central region of the centrifugal separator 300 is subjected to the flow resistance by the third guide vanes 430 of the inverse cyclone unit 400 installed in the direction opposite to the rotation direction of the air, And the dust or the like which has risen upward due to this phenomenon is guided to the spiral space portion 450 of the inverse cyclone portion by the eddy current.

As shown in detail in FIG. 3, the inverse cyclone unit 400, which is a feature of the present invention, includes a discharge hole 410 for discharging the clean air introduced from the centrifugal separator 300 to the outside, A plurality of third guide vanes 430 are integrally formed with the second vanes 220 so as to have an inverted inclination with respect to the second vanes 220, A partition wall 440 spaced apart from the wall and formed of a spiral curved surface, a spiral space portion 440 formed by neighboring partition walls, and having a width corresponding to the width of the partition wall 440, A fourth guide vane 460 disposed equidistantly on the side of the partition wall belonging to the spiral space and lowering the moving speed or the rotational force of the compressed air; The spiral space portion And an outlet hole 480 through which the compressed air is drawn out while being directly connected to the remaining cyclone unit 500. [

The discharge hole 410 is a component for discharging clean air or relatively light dust or the like to which dust has been discharged as described above. The discharge hole 410 includes a plurality of third guide vanes 430, .

The third guiding vanes 430 are provided in different directions from the second guiding vanes 220 of the guiding portion 200 and pass through the centrifugal separating portion 300 to artificially control the flow of the corresponding air, .

As a result of the technical idea of the third guide vanes 430, the flow of light air is somewhat restrained, so that the dust or the like remaining a little is introduced into the spiral space part 450 and is subjected to the re-separation process.

The spiral space part 450 is formed by forming a spiral continuous partition wall 440. At this time, the width of the spiral space part is formed to be increased as the distance from the discharge hole 410 increases, For more effective and better function, it is preferable in the present invention to further adopt the fourth guide vanes 460 as the side of the partition wall.

The fourth guide vanes 460 should be continuously arranged with an inclination in a direction corresponding to the flow of air so as to suppress the rotational force of the air.

The guide part 200 in the present invention includes a bottom part of the conical tube 210 to be installed down to the entrance part 100 where the first guide vanes 110 are located.

This is to allow a quick turning force to be induced against the rising air that goes out of the entrance 100 but not to interfere with the first guide vest 110, Should be spaced a short distance from.

The second guiding vanes 220 are disposed at an angle of 25 to 40 degrees with the path from the right upper end to the lower left point being oblique so as to induce counterclockwise turning of the humid air, The flow path from the left upper end to the lower right end is inclined at 40 to 60 degrees so as to suppress the flow of the compressed air having the counterclockwise movement in the counterclockwise direction and to reduce the entry speed into the discharge hole 410. [ As shown in Fig.

This inclination is not only a minimum condition for imparting the rotational force of the compressed air, but also an appropriate condition not to be interfered with the flow of upwardly moving air.

According to the present invention configured as described above, since the dust collection is performed depending on the blowing air supplied from the silo, an excessive cost is not required, and the functionality is also maximized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be clarified. Therefore, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
