1 to 5 , an apparatus for manufacturing cornstalk shell pellets 2 according to an embodiment of the present invention includes a crushing unit 10 and a separator 100 .

The crushing unit 10 serves to separate the shell pellets 2 and the endothelium 4 while cutting and crushing the cornstalks supplied.

In addition, the separator 100 receives the separated shell pellets 2 and the endothelium 4, and serves to separate and discharge.

In detail, the crushing unit 10 is a facility for receiving cornstalks and cutting and crushing them to a predetermined size or less.

In particular, the crushing unit 10 forms an external shape by the main body 12 so as to discharge the cut and crushed cornstalks after receiving the cornstalks, and the main body 12 includes a crushing cutter 14 inside. be prepared The crushing cutter 14 may be provided in a divided area for cutting and crushing the cornstalk supplied into the body 12 . Of course, the crushing cutter 14 may be deformable in various shapes, and may be provided in various numbers.

At this time, when the cornstalk is crushed by the crushing cutter 14 inside the main body 12 of the crushing unit 10 , a part is separated into the outer shell pellets 2 and the endothelium 4 .

The cornstalks crushed and separated into outer shell pellets 2 and endothelium 4 are transferred to the separator 100 by the transfer conveyor 16 .

In this case, the transfer conveyor 16 may guide the quantitative transfer of the crushed cornstalks.

In addition, the separator 100 includes a casing 110 , a blower 120 , a guide baffle 130 , a floor outlet 140 , and a side outlet 150 .

The casing 110 forms the outer shape of the separator 100, forms an empty space therein, and has a cylindrical shape formed in a rectangular shape along the axial direction. At this time, the casing 110 may be formed in various shapes in cross-section.

In addition, the casing 110 is provided with a predetermined gap from the floor by being supported by the support 118 . Of course, the support 118 is deformable in various shapes.

In addition, the casing 110 has an inlet 112 formed at an upper portion of one side along the axial direction to receive the crushed cornstalk from the transfer conveyor 16 . The inlet 112 is deformable in various shapes.

The blower 120 serves to blow the outside air into the casing 110 from one side along the axial direction of the casing 110 .

The blower 120 is connected to one end of the casing 110 while being supported and fixed on the support 118 to blow outside air into the casing 110 .

For this reason, the separated outer shell pellets 2 and the inner shell 4 of the cornstalk introduced through the inlet 112 move (flow) to the other side along the axial direction of the casing 110 . In particular, one or more blowers 120 are provided at one end of the casing 110, and two blowers are provided for convenience. At this time, two or a plurality of blowers 120 may be controlled to operate simultaneously or in part according to the amount of the shell pellets 2 and the endothelium 4 introduced into the inlet 112 .

In addition, the guide baffle 130 is provided on the inner surface of the casing 110 and the inner surface of the inlet 112 in order to set the input and transport directions of the crushed cornstalks introduced through the inlet 112 .

At this time, the endothelium 4 in a state attached to the outer skin is partially separated while colliding with the guide baffle 130 .

Of course, the guide baffle 130 can be deformed into various shapes.

In particular, the guide baffle 130 provided on the inner side of the lowermost side of the inlet 112 is inclined surface 132 so that the falling outer shell pellets 2 and the inner shell 4 fall while facing the other side of the casing 110 . to form

The outer shell pellets 2 and the inner shell 4 falling into the casing 110 while colliding with the guide baffle 130 flow in the other direction of the casing 110 by the blowing force of the blower 120 .

And, the floor outlet 140 is through-hole in the bottom surface of the casing 110, to induce the discharge of the shell pellets (2).

In addition, the side outlet 150 is a through hole in the lower circumferential surface of the casing 110, to induce the discharge of the endothelium (4).

In particular, the specific gravity of the shell pellets (2) is greater than the specific gravity of the endothelium (4). So, when the blower blows, the outer shell pellets 2 naturally fall after flowing a shorter distance than the inner shell 4, and the inner shell 4 naturally falls after flowing further than the shell pellets 2 . In addition, the endothelium 4, when the blower 120 blows, falls after being scattered while being scattered more than the outer shell pellets 2 in the direction of both edges in the inside of the casing 110 .

In particular, the guide baffle 130 provided on the inner side of the lowermost side of the inlet 112 is lower so that the falling outer shell pellets 2 and the inner shell 4 fall to the approximately central portion along the axial direction of the casing 110 . A curved surface 134 of arc trajectory convex in the direction is formed.

So, the shell pellet 2 and the inner shell 4 fall to the other side of the casing 110 through the inclined surface 132 of the guide baffle 130 at the lowermost side and at the same time fall in the other direction of the casing 110 by the curved surface 134. It will fall approximately to the center of the width direction.

And, the floor outlet 140 is formed along the approximately central portion with respect to the width direction in the interior of the casing 110, and induces the discharge of the outer shell pellets (2) of a smaller specific gravity than the specific gravity of the endothelium (4).

In addition, the side outlet 150 induces the discharge of the endothelium 4 that falls after being scattered while more scattered than the outer shell pellets 2 in the direction of the edge of the casing 110 when the blower 120 blows.

At this time, so that the floor outlet 140 and the side outlet 150 are partitioned, the casing 110 may form a portion corresponding to the side outlet 150 among the bottom surface higher than the portion corresponding to the floor outlet 140. there is. To this end, the casing 110 forms a slope member 119 inclined across the floor outlet 140 side and the side outlet 150 side.

Accordingly, the lighter shell pellets 2 among the shell pellets 2 are discharged to the floor outlet 140 along the slope member 119 while flowing to the side outlet 150 side by the blowing force and then falling.

In particular, as the floor outlet 140 and the side outlet 150 are formed along the axial direction of the casing 110 excluding the direct downward direction to the inlet 112 of the casing 110, the outer shell pellet 2 and the inner shell (2) 4) is separated by the blowing force of the blower 120 and then is induced to be separated and discharged through the corresponding floor outlet 140 and the side outlet 150 .

At this time, the volume of the relatively light endothelium 4 is larger than the volume of the relatively heavy shell pellets (2). And, in order to prevent or reduce the endothelial 4 from being discharged to the floor outlet 140 , the casing 110 is provided with a screening sieve at a position corresponding to the floor outlet 140 .

The screening sieve induces the discharge of the outer pirellet with a small volume, and forms a hole sized to filter the bulky endothelium (4). The endothelium 4 filtered through the screening sieve is induced to be discharged to the side outlet 150 while being dispersed by the blowing force of the blower 120 .

In addition, the casing 110 may be provided with an intake pump 160 on the other side to guide the external air blown by the blower 120 to flow intensively along the axial direction of the casing 110 .

That is, when the intake pump 160 operates to intake outdoor air from the other side along the axial direction of the casing 110 , the outside air by the blower 120 operated from one side of the casing 110 is forced toward the intake pump 160 . is moving For this reason, the shell pellets 2 and the inner shell 4 are separated and discharged into the floor outlet 140 and the side outlet 150 while being dispersed along the axial direction of the casing 110 by the forced flowing external air.

At this time, the casing 110 may have an exhaust port 114 on the other peripheral surface to which the intake pump 160 is connected.

So, as the outside air is exhausted through the intake pump 160 and the exhaust port 114 , the outside air by the blower 120 smoothly flows.

In particular, as the outside air is exhausted through the exhaust port 114 and the intake pump 160 disposed at different positions in the casing 110, the shell pellets 2 and the inner shell 4 fall more and more scattered, so that the corresponding Concentrated discharge in a specific area of the floor outlet 140 and the side outlet 150 can be prevented.

In addition, the casing 110 may be provided with a screen filter 116 on the exhaust side of the outside air. The screen filter 116 is provided on the inside of the casing 110 corresponding to the exhaust port 114 and the intake pump 160 to prevent scattering dust and scattering foreign substances from being discharged. Of course, the screen filter 116 can be deformed into various shapes.

In addition, when the external air by the blower 120 directly collides with the outer shell pellets 2 and the inner shell 4, the shell pellets 2 and the inner shell 4 are caused by strong blowing force in the axial direction of the casing 110 . It is not evenly discharged over the whole of the floor outlet 140 and the side outlet 150, but is scattered to the other side of the casing 110 and then concentrated.

To prevent this, the casing 110 is provided with a diffusing block 170 to flow while spreading the outdoor air blown by the blower (120). As the external air blown by the blower 120 is divided by the diffusing block 170 and the strength (blowing power) is weakened, the shell pellets 2 and the inner shell 4 are axial in the interior of the casing 110 . It will fall naturally as it flows slowly along the

One or more diffusing blocks 170 are disposed adjacent to the inlet 112 and the blower 120 within the casing 110 . Of course, the diffusing block 170 can be deformed into various shapes.

In addition, the casing 110 is provided with a separating block 180 in order to change the position in which the outer shell pellets 2 and the endothelium 4 having different specific gravity fall while flowing.

That is, the separating block 180 is provided on the bottom surface of the casing 110, and has a relatively large specific gravity and serves to induce the shell pellets 2 flowing at a relatively low height inside the casing 110 to be caught. do. The shell pellets 2 caught in the separating block 180 are guided to be discharged to the floor outlet 140 .

Accordingly, the casing 110 may have the floor outlet 140 on one side along the axial direction with respect to the separating block 18 , and the side outlet 150 may be disposed on the other side.

Of course, the separating block 180 can be deformed into various shapes.

The separated and discharged shell pellets 2 may be tightly aggregated to a predetermined size by a compressor (not shown) in the next process.
