Description

[Technical field]

[0001] The present invention relates to a conveyor that separates and removes impurities attached to waste, and more particularly to a sorting conveyor that separates and removes impurities attached to waste by using air pulses, in which the waste is struck with pulsed air while being transported by the conveyor, causing the waste to turn over and knock off the impurities attached to the waste, which can be separated and removed. [Background technology]

[0002] Generally, various waste materials generated at industrial sites are separated by type, and those that can be recycled are recycled through a reprocessing process. Soil and glass powder attached to waste vinyl and waste plastic must be removed during the recycling process, and this invention is essential for smooth incineration and the production of high-purity pyrolysis oil, as it keeps the content of impurities to a low level.

[0003] Conventionally, impurities have been separated from waste using separate equipment such as air separators and vibration separators, but this has problems such as the high cost of the sorting line facilities and the increased number of processes, which lengthens the work time.

[0004] In addition, the waste is transported from the sorting line to each process through a conveyor system, but conventional conveyors simply transport the waste. If impurities are separated during the process of transporting the waste, the sorting line can be simplified, which has a huge effect of significantly reducing equipment costs and shortening work time, so there is a need for a conveyor system that can remove impurities.

[0020] The effects of the sorting conveyor of the present invention, which separates and removes foreign matter adhering to waste by using air pulses, will now be described in detail.

[0021] FIG. 1 is a plan view showing the structure of a conveyor according to the present invention, FIG. 2 is a front view showing the structure of a conveyor according to the present invention, FIG. 3 is a side sectional view showing the structure of a conveyor according to the present invention, and FIG. 4 is a partially enlarged view showing the connecting structure of a chain and a slate according to the present invention.

[0022] As shown in these drawings, the sorting conveyor for separating and removing impurities attached to waste using air pulses according to the present invention includes sprockets 20 installed on both the front and rear ends of a base frame 10; a chain 30 wound around both sprockets 20; a plurality of slates 40 connecting the chains 30 on both sides and fixed at regular intervals; and an air line 50 fixed to the base frame 10 so as to be located below the slates 40, which instantly blows compressed air in the direction of the waste placed on the top of the slates 40 to detach impurities attached to the waste.

[0023] The base frame 10 is formed in the shape of a square frame by connecting a plurality of frames horizontally and vertically.

[0024] The sprockets 20 are installed so as to rotate on both the front and rear ends of the base frame 10. The front and rear sprockets 20 are connected to each other by a shaft to rotate.

[0025] The chain 30 is installed by being wound around the front and rear sprockets 20 on both sides, and rollers 32 are provided between the front and rear ends of a pair of opposing plates 31, which are fixed by pins 33. The front and rear ends of the plates 31 are continuously overlapped and connected to form a link-like structure. An extension piece 34 is extended from the inner plate 31, which is extended from the plate 31 but bent horizontally, and one or more fastening holes 35 are formed in the extension piece 34 so that a slate 40 can be connected. A support frame for preventing slack in the chain 30 is installed at the bottom of the chain 30 in the direction in which the chain 30 moves.

[0026] The slate 40 is a long plate shape that connects both sides of the chain 30 and is fixed at a fixed interval. The slate 40 is bent at both ends of the shorter side to prevent it from bending easily, and fastening holes 45 corresponding to the fastening holes 35 of the extension piece 34 of the chain 30 are formed at both ends of the longer side, and the slate 40 is fixed to the chain 30 by using bolts and nuts with both fastening holes 35, 45 aligned. Since the interval between the plates 31 of the chain 30 is fixed, the slate 40 installed thereon also has a fixed interval, and is installed so that a gap is generated between the slates 40 through which compressed air and impurities can pass. Here, the width of the slate 40 may vary depending on the type of waste, and the plates 31 may be installed at fixed intervals.

[0027] The airline 50 is fixed to the base frame 10 so as to be located between the upper and lower chains 30, and is composed of a pipe equipped with jet nozzles 51 at regular intervals, and the pipes are installed crossing both chains 30 at regular intervals. Here, the jet nozzles 51 are installed facing upwards, and instantly blow compressed air toward the waste placed on the slates 40 to detach impurities attached to the waste. The compressed air blown from the jet nozzles 51 is blown through the gaps between the slates 40 and blown toward the waste, and the waste is turned over by the compressed air, and the impurities are simultaneously detached, so that the waste can be separated evenly and without omissions. This airline 50 can be connected to an air compressor 52 and a multi-timer 53 so that the compressed air can be blown out sequentially.

[0028] Meanwhile, a collection tube 60 for collecting the falling foreign matter is provided at the bottom of the airline 50. The collection tube 60 is wide at the top and narrow at the bottom, so that the foreign matter detached from the waste falls into the collection tube 60 and is collected in one place.

[0029] 5 to 9 are exemplary diagrams illustrating the structure of a slate according to the present invention, and the shape of the slate 40 can be changed according to the type of waste.

[0030] The slate 40 can be formed with through holes 41 through which air and impurities pass, as shown in Figs. 5 and 6. In the case of a slate 40 without through holes 41, the waste hidden by the slate 40 may not be properly desorbed because compressed air is not injected, and the slate 40 may shake due to the injected pressure, causing impurities to accumulate on the top surface of the slate 40. However, in the case of a slate 40 with through holes 41, compressed air is injected even through the through holes 41, so the waste portion blocked by the slate 40 is minimized, the effect of desorbing impurities is maximized, and impurities pass through the through holes 41, preventing impurities from accumulating on the top surface of the slate 40. In addition, since compressed air is injected through the through holes 41, the waste can be turned over more effectively, and there is an effect of preventing the slate 40 from shaking because there is less resistance to the impact of the compressed air.

[0031] The through holes 41 of the slate 40 can be formed long in the length direction of the slate 40 as shown in Fig. 5. In this case, since a large amount of compressed air passes through the slate 40, it has the effect of easily turning over even relatively heavy waste, and is preferable to use when a large amount of impurities are attached to the waste.

[0032] The through holes 41 of the slate 40 can be formed at regular intervals as shown in Fig. 6. Here, the through holes 41 can be formed in one or more rows, and can be formed in a circular, triangular, square, etc. shape. In this case, the amount of compressed air passing through is small, which is effective for turning over relatively light waste, and is preferable when a small amount of impurities are attached to the waste.

[0033] The slate 40 may be formed with a zigzag shape on one or both sides as shown in Fig. 7. In this case, even if the gap width between the slates is the same, smaller and longer waste materials cannot pass through the gap.

[0034] The slate 40 may be formed with an inverted triangular cross section as shown in Fig. 8. If the slate 40 is simply a flat surface, the injected compressed air will bounce off the slate 40, obstructing the flow of compressed air passing between the slates, and the slate 40 will vibrate due to the injected pressure, but if the slate 40 is formed with an inverted triangular shape, an inclined surface is formed with a narrow lower part and a wide upper part, and the compressed air injected to the slate 40 is guided to the gaps between the slates 40, resulting in a stronger injection and no vibration of the slate 40.

[0035] FIG. 9 is a plan view illustrating the structure of a conveyor according to another embodiment of the present invention, FIG. 10 is a partially enlarged view illustrating a slate according to another embodiment of the present invention, and FIG. 11 is a diagram illustrating the operation of a striking plate according to another embodiment of the present invention.

[0036] As shown in these drawings, a sorting conveyor for separating and removing impurities attached to waste using air pulses according to another embodiment of the present invention has rod-shaped fixed frames 11 installed at regular intervals on a base frame 10 so as to be located below a slate 40, the slate 40 has an open groove 42 open to one side, and a striking plate 43 is connected to the open groove 42 by a hinge 44, so that when the slate 40 moves, the striking plate 43 positioned vertically hits the fixed frame 11 and rotates horizontally to strike the waste placed on the slate 40.

[0037] The fixed frames 11 were fixedly installed on the base frame 10 at regular intervals and were installed parallel to the conveyor width direction, i.e., the length direction of the slate 40.

[0038] The slate 40 is in the form of a long plate, and has an open groove 42 open on one side, and one end of a striking plate 43 is connected to the open groove 42 by a hinge 44, and the opening groove 42 is selectively opened or closed as the striking plate 43 rotates around the hinge 44. One or more opening grooves 42 and striking plates 43 can be formed on one slate 40, and as shown in the drawings, one slate 40 can have one at the center, and the next slate 40 can have two on both sides, and these can be installed alternately.

[0039] The striking plate 43 moves in a vertical position due to its own weight as shown in Fig. 11(A), or when it hits the fixed frame 11 as shown in (B), it rotates around the hinge 44 as shown in Fig. 11(C) and moves to a horizontal position as shown in (C), striking the waste placed on the slate 40 to detach the foreign matter attached to the waste, and when it passes the fixed frame 11, the striking plate 43 moves again in a vertical position due to its own weight as shown in (D). That is, the compressed air sprayed through the air line 50 and the striking plate 43 have the effect of more effectively detaching the foreign matter attached to the waste. Or, in the case of large foreign matter that cannot pass through the gaps between the slates 40, the opening groove 42 is wider than the gaps between the slates 40, so that the foreign matter passes through the opening groove 42 and falls.

[0040] In addition, a slanted reinforcing plate 46 is provided vertically on the lower surface of the striking plate 43 so that the reinforcing plate 46 hits the fixed frame 11. The reinforcing plate 46 prevents deformation of the striking plate 43 and allows the fixed frame 11 and the slate 40 to be spaced apart sufficiently, thereby preventing interference between the slate 40 and the fixed frame 11.

[0041] Alternatively, a wear plate 12 can be attached to the tip of the fixed frame 11. The wear plate 12 is made of rubber or fabric material that can absorb shock, preventing damage to parts and preventing noise generation. Wear caused by repeated collisions occurs only on the wear plate 12, so regular replacement of only the wear plate 12 at low cost has the effect of extending the life of other parts.

[0042] In this way, the slate 40 equipped with the striking plate 43 is repeatedly installed in sequence, such as the slate 40 with the through hole 41 formed as shown in FIG. 9 and the zigzag slate 40, thereby achieving the effect of taking advantage of all the advantages of each shape as described above.
