Description

[0001] Apparatus for removing impurities in earth [

The present invention relates to an in-soil foreign matter separating apparatus.

There are about 1,500 landfill facilities in Korea and currently 230 landfill facilities are in operation. However, it is difficult to secure landfill facilities as resident evacuation facilities and huge economic and social costs are required to secure new ones.

Currently, the government stabilizes existing landfill facilities, and then develops recycled landfills with excavated / sorted landfills, or excavates and removes pollutants to develop residential and industrial land.

Thus, excavation / screening is essential for recycling or development of reclaimed landfills. At this time, soil and nonflammable materials can be reused in the landfill by sorting / separating the excavated landfill by each property, and combustible species can be used as raw materials of solidified fuel (SRF) to expand the utilization of the landfill site.

As shown in the patent documents of the following prior art documents, the selection of the landfill wastes is carried out by using a Trommelscreen having an average diameter of 30 mm to 40 mm in the diameter of the screening compartments. In the first selection soil, a large amount of organic foreign matters And the content of the organic foreign substance of 1% or less, which is the standard of recycling of the field, is not satisfied. Accordingly, the secondary sorting apparatus is combined with the subsequent process to re-sort (secondary sort) the organic matter in the primary sorted soil.

Specifically, the secondary screening apparatus selects the buried soil in the form of a vibration screen and a trommel screen having a screening port diameter of Ø15 mm or less, under various water content conditions. However, as shown in Table 1 below, when selecting waste in good condition, it is possible to select organic matters in the soil, but when selecting the waste in a normal state or in a bad state, frequent retinal force phenomenon occurs, There is a problem that the foreign matter can not be selected and as a result, the recycling width of the selected soil is lowered.

division Good state Normal state Bad state Function cost Condition Less than 15% waste Less than 15 ~ 20% Waste Less than 25 ~ 35% Waste Waste Properties Sandy soil 80% + clayey soil 20% Sandy soil 80% + clayey soil 20% Sandy soil 80% + clayey soil 20% Waste rate Soil 50% + Flammable 50% Soil 50% + Flammable 50% Soil 50% + Flammable 50%

In order to solve these problems, it is emphasized that there is a need for an apparatus for separating foreign matters in soil, which can re-select organic matters in the soil regardless of the characteristics of the landfill waste and the water content.

It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements have the same numerical numbers as much as possible even if they are displayed on different drawings. Also, the terms "first "," second ", and the like are used to distinguish one element from another element, and the element is not limited thereto. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The in-soil foreign matter separating apparatus according to the present embodiment includes a plurality of shafts 100 arranged in parallel to each other, a plurality of disks 200 spaced apart from each other along the longitudinal direction of the shaft 100, A plurality of elastic members 300 disposed between the plurality of discs 200 and disposed between the plurality of discs 200, an elastic member 300 disposed inside the elastic members 300, A second cap 320 which is disposed between the plurality of discs 200 and in which an elastic member 300 is disposed and the other end of the elastic member 300 is engaged; And a first gap adjusting unit 400 provided at the shaft 100 for adjusting a predetermined gap by pressing the disk 200 provided at the outermost position with respect to the longitudinal direction of the shaft 100. In addition, Accordingly, the first cap 310 slides inward of the second cap 320 or outward of the second cap 320, The.

Basically, as shown in FIG. 1B to FIG. 1C, when the primary soil is selected from the Trommelscreen or the like, (A) The foreign matter is transferred from the upper side of the disc 200 and discharged (B) according to the rotation of the disc 200. The foreign matter passes through between the discs 200, (C). Also, the gravel discharged to the lower side of the disc 200 can be conveyed through the conveyor belt 990 (D). Through this process, soil and foreign matter can be selected. Therefore, the foreign matter separating device according to the present embodiment can separate foreign substances from the soil (sanitary or unsanitary landfill waste sorting) (improvement of field recycling). In addition, it is possible to re-select the gravel in the intermediate treatment process of construction waste (recycling of gravel and selection of aggregate contained in the gravel).

As shown in FIG. 2, the soil foreign object separation apparatus according to the present embodiment includes a plurality of shafts 100, a plurality of disks 200, a plurality of elastic members 300, a first cap 310, A cap 320, and a first gap adjusting means 400, which will be described in detail.

The shaft 100 supports the disc 200, the elastic member 300, the first cap 310, the second cap 320, the first gap adjusting means 400, and the like. And is formed into a rod and rotated. Here, a plurality of shafts 100 are provided and are arranged side by side on a virtual plane. At this time, the shaft 100 may include a square pipe 110, a fastening portion 120, and a processing shaft 130, as shown in FIG. Specifically, the square pipe 110 is formed in a rectangular shape with respect to the vertical plane, and the disk 200, the elastic member 300, the first cap 310, the second cap 320, and the like may be disposed. The fastening part 120 may be formed in a square pillar shape and may be inserted into the end of the square pipe 110. At this time, the fastening part 120 can be inserted into the end of the square pipe 110 by fitting. The machining shaft 130 extends from the coupling portion 120 in a cylindrical shape and includes a first gap adjusting means 400, a bushing 410, a first gap adjusting nut 420, a sprocket 960, . As described above, the reason why the shaft 100 is coupled to the square pipe 110 and the coupling part 120 in a fitting manner is that the square pipe 110 does not replace the entire shaft 100 when worn, 110 are selectively replaced. In addition, by using the square pipe 110, the weight is light and the operator can be comforted at the time of exchanging the disk 200. Since the disc 200, the elastic member 300, the first cap 310 and the second cap 320 coupled to the square pipe 110 prevent wear of the square pipe 110, 110) may use a minimum thickness in consideration of warping or deformation.

The disk 200 (see FIG. 2) substantially plays a role of sorting foreign matter in the soil, and is formed in a plate shape. Here, a plurality of discs 200 are provided and are spaced apart from each other along the longitudinal direction of the shaft 100. At this time, the disc 200 provided in one shaft 100 may be staggered from the disc 200 provided in the adjacent shaft 100 of one shaft 100. That is, an arbitrary disc 200 may be disposed between two discs 200 provided on an adjacent shaft 100. When a plurality of discs 200 are rotated together with the shaft 100 and waste is supplied to the upper side of the disc 200, the discs 200 are rotated to discharge the discs 200 between the discs 200, And is transported along the rotation direction from above the disc 200 in accordance with the rotation. Meanwhile, the material of the disc 200 is not particularly limited, but it may be formed of MC nylon (Mono Cast Nylon). Here, MC nylon is a polymerized / molded nylon monomer under atmospheric pressure. It improves the properties of nylon and has excellent characteristics that can not be realized by injection molding or extrusion molding. In addition, MC nylon is lighter than iron, which makes it easy to assemble and replace, and has the advantage of continuous use at high temperature / high speed rotation. The foreign matter separating apparatus according to this embodiment reselects primary selected soil from the Trommelscreen or the like, so that it is possible to form the disk 200 as MC nylon because the abrasion and damage due to heavy materials are relatively small.

5, the central portion (square pipe 110) of the shaft 100 is formed in a rectangular shape with respect to the vertical plane, and a rectangular shape corresponding to the central portion of the shaft 100 is formed at the center of the disk 200, A coupling hole 240 is formed. The center of the shaft 100 is inserted into the coupling hole 240 formed in the disc 200 so that the disc 200 can be coupled to the shaft 100. Since the coupling hole 240 of the quadrangular disc 200 is coupled to the center of the shaft 100 having a rectangular vertical section as described above, the disc 200 can rotate together with the shaft 100.

The elastic member 300 (see FIG. 2) serves to maintain a predetermined gap between the plurality of disks 200 constantly. Here, the elastic member 300 may be disposed between two adjacent discs 200 among the plurality of discs 200, and may be disposed within a space formed by the first cap 310 and the second cap 320. For example, as shown in FIG. 5, the disc 200, the second cap 320, the elastic member 300, the first cap 310, and the disc 200 are repeatedly inserted into the shaft 100, So that the elastic member 300 can be disposed between the adjacent two discs 200. At this time, the plurality of elastic members 300 have a predetermined elasticity, so that a predetermined gap between the plurality of disks 200 can be maintained constant. 6A to 6B, the first gap adjusting means 400 adjusts the force of pressing the disc 200 provided at the outermost position with respect to the longitudinal direction of the shaft 100, The elastic member 300 disposed between the disc 200 and the elastic member 300 can be expanded or contracted, thereby adjusting a predetermined distance between the discs 200. Specific details of the elastic member 300 will be described later. On the other hand, the type of the elastic member 300 is not particularly limited, but may be, for example, a compression spring that resists the force to be compressed.

The first and second caps 310 and 320 (see FIG. 2) surround and cover the elastic member 300. Here, the first cap 310 and the second cap 320 are disposed between the plurality of discs 200, and the elastic member 300 is disposed therein. At this time, one end of the elastic member 300 is caught in the first cap 310, and the other end of the elastic member 300 is caught in the second cap 320. 5, the first cap 310 is formed in a tubular shape and includes a first main body 313 in which an elastic member 300 is disposed, and a second main body 313 extending from a distal end of the first main body 313 And may include a first protrusion 315 which protrudes in the direction of the center axis of the first main body 313 and is hooked at one end of the elastic member 300. Similarly, the second cap 320 is formed in a tubular shape, and includes a second body 323 in which the elastic member 300 is disposed, and a second body 323 formed from the distal end of the second body 323, And a second protrusion 325 protruding in the central axis direction and hooked to the other end of the elastic member 300. At this time, the second body 323 of the second cap 320 may be larger in diameter than the first body 313 of the first cap 310. 6A and 6B, the first main body 313 of the first cap 310 is moved to the second main body 313 of the second cap 320 by adjusting the predetermined interval between the discs 200. Accordingly, And can move relative to each other. The first body 313 of the first cap 310 may contact the second projection 325 of the second cap 320 if the predetermined distance between the disks 200 is as narrow as possible 6b). Conversely, since the first body 313 of the first cap 310 and the second body 320 of the second cap 320 are overlapped even if a predetermined gap between the disks 200 is maximized, The first cap 310 and the second cap 310 may surround and cover the elastic member 300. As a result, since the elastic member 300 is disposed inside the space formed by the first cap 310 and the second cap 320, the elastic member 300 is not exposed to the outside, It is possible to prevent the phenomenon of sticking to or attaching to the body 300. Since both ends of the elastic member 300 are engaged with the first protrusion 315 of the first cap 310 and the second protrusion 325 of the second cap 320 by the elastic force of the elastic member 300 The first cap 310 and the second cap 320 are pressed in the direction of the disc 200. 6A and 6B, the first cap 310 and the second cap 320 are pressed by the elastic member 300 and the first gap adjusting means 400, The first cap 310 slides inside and outside the second cap 320 and can move to correspond to a predetermined gap between the disks 200. [ That is, the first cap 310 and the second cap 320 cover the elastic member 300, and the width of the elastic member 300 can be adjusted in correspondence with a change in the interval between the disks 200. Although the first cap 310 is described as sliding on the inner and outer sides of the second cap 320 for the sake of convenience of description, And the relative movement between the first cap 320 and the second cap 320.

The first gap adjusting means 400 (see FIG. 4) controls a predetermined gap between the disks 200. The first gap adjusting means 400 is provided at the distal end of the shaft 100 to press the disc 200 provided at the outermost position with respect to the longitudinal direction of the shaft 100, And adjusts a predetermined interval between the disks 200 while expanding or contracting the elastic members 300 arranged. Specifically, as shown in FIGS. 7A and 7B, the first gap adjusting means 400 may include a bushing 410 and a first gap adjusting nut 420. At this time, the bushing 410 is formed in a cylindrical shape and is coupled to the shaft 100, and presses the disk 200 provided at the outermost position with respect to the longitudinal direction of the shaft 100. The first gap adjusting nut 420 is screwed on the thread 105 formed on the shaft 100 and moves the bushing 410 in the longitudinal direction of the shaft 100 as it rotates. Accordingly, by moving the bushing 410 in the longitudinal direction of the shaft 100 while rotating the first gap adjusting nut 420, the bushing 410 can adjust the force for pressing the disk 200 provided at the outermost position have. As the bushing 410 controls the pressing force of the disc 200, the pressing force applied to the elastic member 300 disposed between the discs 200 changes and the elastic member 300 expands or shrinks And the disc 200 can be adjusted. At the same time, the first cap 310 slides on the inside and outside of the second cap 320, and can correspond to a predetermined interval between the disks 200. As a result, when the first gap adjusting nut 420 is rotated, the elastic member 300 expands or contracts while the first cap 310 slides on the inside and the outside of the second cap 320, It is possible to freely adjust the interval, and accordingly, it is possible to select foreign matters in the soil by taking into account the characteristics of the various wastes and the water content ratio.

Meanwhile, as shown in FIG. 8, the plurality of shafts 100 arranged in parallel can be supported by the frame 500 as a whole. In detail, the frame 500 may have a discharge opening 510 through which the selected gravel is discharged at the center, and a lower chute 520 for guiding the selected gravel under the discharge opening 510 have. More specifically, the frame 500 may include a first body 600 and a second body 700. Here, the first body 600 is formed in an "L" shape, and can be fixed to the frame 500 by bolts, nuts, or the like. 9, a first depressed portion 610, which is depressed downward, is continuously provided at an upper end of the first body 600, and a plurality of shafts 100 May be provided with a bearing 140 for rotatably fixing the distal end of the shaft. Further, the first cover 620 may be coupled to the upper side of the first depression 610. The second body 700 is formed in an "L" shape similar to the first body 600 and is disposed inside the first body 600 to move horizontally with respect to the first body 600 It is possible. 10A, a long hole 540 is formed in the frame 500 in one direction (the longitudinal direction of the shaft 100) relative to the other direction (one direction and perpendicular), and the long hole 540 is formed in the frame 500. [ The second body 700 can move horizontally with respect to the first body 600 by being coupled with the nut 550a and the bolt 550b. 8, the second body 700 includes a first gap adjusting unit 400 and a bushing 410 and a disc 200 disposed at an outermost position with respect to the longitudinal direction of the shaft 100. [ As shown in FIG. 9, a second depression 710, which is depressed downward, is continuously provided at an upper end of the second body 700 so that the shaft 100 can pass therethrough. The second cover 720 may be coupled to the upper side of the second depression 710.

As shown in FIGS. 11A and 11B, a second gap adjusting unit 800 may be further provided to adjust the gap between the first body 600 and the second body 700. [0053] FIG. The second gap adjusting unit 800 is provided between the first body 600 and the second body 700 to move the second body 700 horizontally relative to the first body 600, The distance between the first body 600 and the second body 700 can be adjusted. Specifically, the second gap adjusting means 800 may include a coupling body 810, a gap adjusting rod 820, and a second gap adjusting nut 830. Here, the coupling body 810 is coupled to the second body 700, and an insertion groove 815 (see FIG. 10B) is formed. Further, the interval adjusting rod 820 is rotatably coupled to the insertion groove 815 at one end. More specifically, the insertion groove 815 is opened in the direction of the first body 600, a step 817 is formed in which the width of the insertion groove 815 is narrowed toward the first body 600, The engaging nut 825 engaged with the step 817 of the insertion groove 815 is screwed. Thus, the spacing rod 820 can be freely rotatably coupled to the insertion groove 815 of the coupling body 810. Meanwhile, as shown in FIG. 10A, the gap adjusting rods 820 pass through the first body 600, and the other ends are disposed outside the first body 600. The second gap adjusting nut 830 is screwed to the thread 823 formed on the gap adjusting rod 820 and fixed to the plate 827 provided outside the first body 600 by welding or the like. 11A to 11B, when the gap adjusting rods 820 are rotated, the gap adjusting rods 820 move horizontally along the second gap adjusting nuts 830, so that the second bodies 700 Can be moved along the longitudinal direction of the gap adjusting rods 820. [ As a result, the gap between the first body 600 and the second body 700 can be freely adjusted by rotating the gap adjusting rods 820.

Meanwhile, the first gap adjusting means 400 and the second gap adjusting means 800 may be operated together. Specifically, the second body 700 moves together with the bushing 410 of the first gap adjusting means 400, so that when the bushing 410 of the first gap adjusting means 400 moves, The second body 700 should also be moved by the second body 800. That is, when the predetermined interval between the disks 200 is adjusted by rotating the first interval adjusting nut 420 of the first interval adjusting means 400 and moving the bushing 410, the distance corresponding to the moving distance of the bushing 410 The second body 700 can be moved by rotating the gap adjusting rods 820 of the second gap adjusting means 800. [

In addition, as shown in FIG. 12, the in-soil foreign matter separation apparatus according to the present embodiment may be provided with the injection means 1000. Here, the jetting means 1000 blows a gas (high-pressure air or the like) to a plurality of disks 200 while reciprocating along the longitudinal direction of the shaft 100, thereby moving the disk 200 and the first and second caps 310, 320 or the like to prevent the adherence of soil or other foreign matter. By providing such injection means 1000, no separate cleaning work is required, so that the continuity of the foreign matter separation work in the soil can be increased, and the convenience of the operator can be improved. Specifically, the injection means 1000 may include a support frame 1100, a transfer means 1200, and a nozzle 1300. [ Here, the support frame 1100 may have an opening 1150 corresponding to a predetermined number of the shafts 100 arranged in parallel at the center, and may be coupled to the upper side of the first body 600. The conveying means 1200 reciprocates along the opening 1150 of the support frame 1100 and the nozzle 1300 is coupled to the conveying means 1200 to eject substantially the gas to the plurality of discs 200 . The nozzle 1300 coupled to the conveying means 1200 can inject gas onto the disk 200 while reciprocating with respect to the opening 1150 of the support frame 1100. [ At this time, the nozzle 1300 can be supplied with gas through the hose, and the hose can be protected by a cable carrier 1320.

More specifically, the conveying means 1200 may include a conveying plate 1210 and a conveying motor 1220. Here, the transfer plate 1210 is fixed to the nozzle 1300, extends perpendicularly to the longitudinal direction of the shaft 100, and has both ends slidably supported by the support frame 1100. [ The conveying motor 1220 is fixed to one end of the conveying plate 1210 and is gear-engaged with the supporting frame 1100 so that the conveying plate 1210 is supported in the longitudinal direction of the shaft 100 with respect to the supporting frame 1100 Move it in parallel. That is, the transfer plate 1210, to which the nozzle 1300 is fixed by the transfer motor 1220, can reciprocate with respect to the opening 1150 of the support frame 1100. At this time, a first rail 1110 is provided at one side of the support frame 1100, and a first roller 1230 is provided at one end of the transfer plate 1210 to rotate along the first rail 1110. Similarly, a second rail 1120 may be provided on the other side of the support frame 1100, and a second roller 1240 may be provided on the other end of the transfer plate 1210 to rotate along the second rail 1120 have. The first roller 1230 provided at one end of the transfer plate 1210 is coupled to the first rail 1110 and the second roller 1230 provided at the other end of the transfer plate 1210 is coupled to the second rail 1120. [ The transfer plate 1210 can slide with respect to the support frame 1100. [ Further, the feed motor 1220 may be coupled onto a support plate 1215 which is coupled to one end of the feed plate 1210. The first rail 1110 may include a first rail 1113 and a second rail 1115 arranged in parallel to the lower side of the support plate 1215. The first roller 1230 is coupled to the lower surface of the support plate 1215 and rotatably supports the first 1-1 roller 1233 and the 1-2 rail 1115 which rotate along the 1-1 rail 1113 And a second roller 1235 that rotates along the first axis. That is, the first rail 1110 may include two rails (the first rail 1113, the first rail 1115), and the first roller 1230 may also include two rollers (1-1 roller 1233, 1-2 roller 1235). At this time, the groove of the first-first rail 1113 into which the first-first roller 1233 is inserted and the groove of the first-second rail 1115 into which the first-second roller 1235 is inserted may face each other . Thus, the first roller 1230, the first roller 1233, the first roller 1235 and the second roller 1235 are connected to the first rail 1110, the first rail 1113, the second rail 1115, So that it can be stably pivoted. As described above, since the first roller 1230 (the first 1-1 roller 1233 and the 1-2 roller 1235) can be stably rotated, the first roller 1230, the 1-1 roller 1233, 1-2 roller 1235) can support the feed motor 1220 so that the gear engagement between the feed motor 1220 and the support frame 1100 is stably maintained.

Meanwhile, a rack 1105 and a pinion 1225 may be provided for gear coupling between the feed motor 1220 and the support frame 1100. Specifically, the rack 1105 may extend parallel to the direction (the longitudinal direction of the shaft 100) in which the transfer plate 1210 moves to one side (upper surface) of the support frame 1100. Further, the pinion 1225 can be provided on the drive shaft of the feed motor 1220 and can be engaged with the rack 1105. Accordingly, when the feed motor 1220 is driven, the feed plate 1210 is moved while the pinion 1225 rotates in engagement with the rack 1105, so that the nozzle 1300 fixed to the feed plate 1210 also moves The gas can be jetted onto the plurality of discs 200.

In addition, a nozzle cover 1350 may be provided to concentrate the gas ejected from the nozzle 1300 onto the specific disk 200. The nozzle lid 1350 includes a cover body 1353 formed with a through hole 1354 through which the nozzle 1300 is inserted and a nozzle body 1350 formed on the lower surface of the transfer plate 1210, And a lid extension 1355 extending downward from both sides of the lid body 1353 to cover the distal end.

A limit switch 1400 and a contact means 1500 may be provided so that the conveying means 1200 can reciprocate along the opening 1150 of the support frame 1100. [ Here, the limit switch 1400 is a kind of a switch for detecting the position, and when the contact switch 1500 is in contact with the limit switch 1400, the limit switch 1400 operates. Specifically, the limit switch 1400 is provided at both ends of the support frame 1100 through which the conveying means 1200 reciprocates, and the contact means 1500 is provided at one end of the conveying plate 1210. At this time, when the contact means 1500 contacts the limit switch 1400, the driving direction of the feed motor 1220 is switched. 13, when the conveying means 1200 is conveyed in the one direction A by the conveying motor 1220 and the contact means 1500 contacts the limit switch 1400, the limit switch 1400 is turned on, The transfer direction of the drive shaft of the transfer motor 1220 is switched so that the transfer means 1200 can be transferred in the other direction B. [ 14, when the conveying means 1200 is conveyed in the other direction B by the conveying motor 1220 and the contact means 1500 contacts the limit switch 1400, the limit switch 1400 Can switch the direction of rotation of the driving shaft of the feeding motor 1220, and accordingly, the feeding means 1200 can be fed in the one direction (A). As described above, the limit switch 1400 and the contact means 1500 allow the conveying means 1200 to reciprocate along the opening 1150 of the support frame 1100, and as a result, (1300) can also jet the gas to the disk (200) while reciprocating.

More specifically, as shown in FIG. 12, the contact means 1500 can be provided on both sides of the support plate 1215 with the feed motor 1220 at the center. Here, the contact means 1500 may include a tubular member 1510, a pawl member 1520, and a fastening member 1530. At this time, the tubular member 1510 is fixed on the support plate 1215, and is formed into a tubular shape, and a space is provided therein. The pawl member 1520 is provided at its distal end with a contact portion 1525 in contact with the limit switch 1400 and is slidably inserted into the space of the tubular member 1510. [ At this time, the contact portion 1525 is formed by bending the distal end of the pawl member 1520, so that the contact portion 1525 can be in contact with the limit switch 1400 while intersecting the limit switch 1400. The fixing member 1530 may be a bolt or the like and may be inserted into a hole formed in the tubular member 1510 to press the pawl member 1520 to fix the pawl member 1520 to the tubular member 1510 . .

As described above, since the pawl member 1520 is slidably inserted into the space of the tubular member 1510, the distance between the contact portion 1525 of the pawl member 1520 and the limit switch 1400 can be adjusted. The distance between the contact portion 1525 of the pawl member 1520 and the limit switch 1400 can be adjusted and then the pawl member 1520 can be fixed with the fixing member 1530. [ By adjusting the distance between the contact portion 1525 of the pawl member 1520 and the limit as described above, it is possible to freely control the section in which the conveying means 1200 reciprocates along the opening portion 1150 of the support frame 1100 Lt; / RTI >

On the other hand, a plurality of injection means 1000 may be provided, and may be arranged for every predetermined number of shafts 100. For example, as shown in FIG. 12, two injection means 1000 may be provided. However, the present invention is not limited thereto, and as shown in FIG. 15, four injection means 1000 may be provided. At this time, the four injection means 1000 are connected to a compressor 1001, which provides gas, respectively, by a connection line 1003, and each of the connection lines 1003 is connected to a solenoid valve 1005 As shown in Fig. That is, when the solenoid valve 1005 opens the connection line 1003, the injection means 1000 can receive the gas from the compressor 1001 and inject the gas, and when the solenoid valve 1005 is connected to the connection line 1003, The injection means 1000 can not receive the gas from the compressor 1001 and does not inject gas. With this solenoid valve 1005, only one of the plurality of injection means 1000 can inject gas. That is, when any one of the plurality of the injecting means 1000 injects the gas, the remaining injecting means 1000 may not inject the gas. For example, as shown in FIG. 15, when four injection means 1000 are provided, when the first injection means 1000a injects gas, the second injection means 1000b, the third injection means 1000c, And fourth injection means 1000d may not inject gas. In this way, when the gas is injected only by one injection means 1000a, even if the gas pressure (air pressure) generated in the compressor 1001 is not high, the gas pressure (air pressure) is concentrated only on one injection means 1000a And the injection efficiency of the injection means 1000 can be increased.

In addition, the injection timer 1007 and the non-separation timer 1008 may be provided so that the injector 1000 injects the gas for the first predetermined time and does not inject the gas for the second predetermined time. For example, by using the injection timer 1007, the injection means 1000 can be controlled to inject gas for 3 minutes, and control is made so as not to inject the gas for 1 minute by using the differentiation timer 1008 can do.

Meanwhile, as shown in FIG. 16, two or more frames 500 supporting a plurality of shafts 100 may be provided. That is, the plurality of shafts 100 can be classified into two or more groups, and the frame 500 is also provided with two or more, and each frame 500 can support each group of shafts 100 have. Further, a support body 900 for supporting the frame 500 may be provided below the two or more frames 500. At this time, the height of each support 900 may be lowered from one end to the other end. In addition, a tilt adjusting means may be provided for connecting the two or more frames 500 and the support 900 to adjust the inclination of the two or more frames 500 with respect to the ground. When the inclination of the frame 500 with respect to the paper surface is adjusted using the inclination adjusting means, the inclination angle of the plurality of the shafts 100 with respect to the other end direction of the frame 500 It is possible to improve the sorting efficiency in consideration of the characteristics of the soil (clayey soil or sandy soil). In particular, the soil in-soil material separating apparatus according to the present embodiment may include two or more frames 500 to control the inclination of the two or more frames 500 with respect to the ground. Accordingly, the inclination of any one of the frames 500 may be different from the inclination of the other frame 500 relative to the ground. As described above, if the slopes of the respective frames 500 relative to the paper surface are made different, the sorting efficiency can be further improved. For example, two or more frames 500 may include a first frame 500a and a second frame 500b, and a second frame 500b may be disposed at a lower end of the first frame 500a (The frame 500 is composed of two stages). Here, the first frame 500a is the area where the soil is first applied, and the amount of the soil to be sorted is large. Therefore, by setting the inclination of the first frame 500a relative to the ground to a relatively large value, it is possible to process a large amount of soil material. In addition, the second frame 500b needs to be precisely screened in place of a small amount of soil material to be sorted into the area where the selected soil is once put in the first frame 500a. Therefore, by setting the inclination of the second frame 500b relative to the ground relatively small, precise selection is possible. As a result, the inclination of the first frame 500a with respect to the ground can be larger than the inclination of the second frame 500b with respect to the ground. At this time, the inclination of the first frame 500a with respect to the ground can be, for example, about 22 degrees, and the inclination of the second frame 500b with respect to the ground can be, for example, about 18 degrees.

The rotation speed of the shaft 100 supported by the first frame 500a (the rotation speed of the disk 200) and the predetermined gap between the disk 200 and the second frame 500b, which are supported by the first frame 500a, (The rotational speed of the disk 200) of the shaft 100 supported by the disk 100 and the predetermined interval of the disk 200, respectively. Specifically, the rotational speed of the shaft 100 supported by the first frame 500a may be greater than the rotational speed of the shaft 100 supported by the second frame 500b. For example, the rotation speed of the shaft 100 supported by the first frame 500a may be 50 rpm, and the rotation speed of the shaft 100 supported by the second frame 500b may be 40 rpm. The predetermined interval of the disk 200 supported by the first frame 500a may be greater than a predetermined interval of the disk 200 supported by the second frame 500b. For example, the predetermined interval of the disk 200 supported by the first frame 500a may be 13 mm, and the predetermined interval of the disk 200 supported by the second frame 500b may be 9.5 mm. Since the rotation speed of the shaft 100 supported by the first frame 500a and the predetermined gap between the disks 200 are relatively large, the shaft 100 supported by the first frame 500a is relatively small Lt; / RTI > Since the rotation speed of the shaft 100 supported by the second frame 500b and the predetermined gap between the disks 200 are relatively small, the shaft 100 supported by the second frame 500b can be precisely sorted Do.

However, the inclination, the rotation speed, the predetermined interval, and the like are illustrative, and the scope of the present invention is not limited thereto, and a detailed description of a configuration for controlling the rotation speed of the shaft 100 will be described later.

On the other hand, the inclination adjusting means will be described in detail as follows. The inclination adjusting means may include a hinge portion 920, a slope adjusting rod 930, a slope adjusting rod fixing body 940, a hydraulic cylinder 950, and the like. The hinge portion 920 is rotatably coupled to one end of the frame 500 and one end of the supporting body 900. The hinge portion 920 is coupled to the frame 500 by a hinge or the like so that one end thereof is rotated with respect to the frame 500, The inclination adjusting rods 940 are provided on the support 900 to fix the inclination adjusting rods 930 so as to be movable up and down. More specifically, the inclination adjusting rods 940 are formed in a cylindrical shape so that the inclination adjusting rods 930 can be inserted, and the nuts provided at both ends are screwed to the threads of the inclined bar cutting rods 930, The rod 930 can be fixed. The hydraulic cylinder 950 is provided between the other end of the frame 500 and the other end of the support 900 to adjust the distance between the frame 500 and the support 900 by hydraulic pressure.

Further, as shown in Fig. 17, the plurality of shafts 100 can be rotated by a motor 970. Fig. A plurality of shafts 100 are coupled to a motor 970. The sprockets 960 are connected to a motor 970 by a chain (not shown) As shown in Fig. At this time, two or more motors 970 are provided, so that the plurality of shafts 100 can be rotated at the same or different rotational speeds. Specifically, the plurality of shafts 100 may be classified into two or more groups, and at least two motors 970 may be provided, and each motor 970 may rotate the shaft 100 of each group . At this time, the two or more motors 970 can be controlled to have the same or different rotational speeds by using the inverter 980. Thus, if the rotational speeds of the respective motors 970 are equal to or different from each other, the shafts 100 of the respective groups can also be rotated at the same or different rotational speeds. For example, a plurality of shafts 100 may be classified into two groups (a group of shafts 100 supported by a first frame 500a and a group of shafts 100 supported by a second frame 500b) And two motors 970 are provided, so that each motor 970 can rotate the shaft 100 of each group.

As described above, since the plurality of shafts 100 and the plurality of disks 200 can be divided into two or more groups and the rotational speeds of the shafts 100 and the disks 200 can be rotated the same or differently, It is possible to improve the sorting efficiency by adjusting the rotational speed of the disk 200 in consideration of the phenomenon that the foreign matter is caught between the disks 200, the sorting of the soil, the discharge speed of the foreign matter, and the like.
