Description

Artificial Turf Reclaimer

[0001] The present invention relates to a synthetic grass recovery machine, and more particularly, to an artificial grass recovery machine for separating, collecting, crushing, and sorting artificial turf from a construction surface, .

Generally, artificial turf is installed on a playground by a roll wound about tens of meters in length. Such artificial turf is composed of a grass carpet with turf-shaped humanoid hoods and a filler made of granular silica sand and rubber chips filled into human hair. The grass carpet is manufactured in the form of nonwoven fabric by thermoplastic chemical fibers such as PP, PVC, etc., and is laid on a concavo-convex drainage block installed on the ground of the playground after the filler is filled in the artificial hair.

Such artificial turf is dismantled at the athletic field by manual operation at the time of disposal, is transported to the vehicle, is crushed and then discarded. At this time, the grass carpet is rewound and transported in the form of a roll as the filler is charged. However, when the artificial grass is discarded, the grass carpet of the artificial turf must be rolled up in the form of a roll, so that it is very difficult to work and a long working time is required.

In addition, in the case of the filler, it is very difficult to separate the silica sand and the rubber chip from the grass carpet. Therefore, it is inevitable to dispose the entire amount together with the grass carpet. Especially, when the filler is mixed with foreign matters such as dust or turf- It is the fact that it disposes. That is, it is very difficult to separate the filler into silica sand and rubber sand, and all of the filler is discarded together with the grass carpet, because it is virtually impossible to remove the foreign matter from the silica sand and rubber chips.

Therefore, the entire amount of the grass carpet and the filler which can be recycled must be disposed of, thereby causing a problem of causing environmental pollution, and also wasting resources.

In order to solve these problems, the present applicant has proposed an artificial grass collecting machine (Patent No. 10-1100325).

This artificial grass reclaiming machine includes a bogie 103 which forms a base and moves on the ground on which the artificial grass T is installed as shown by reference numeral 101 in Fig. 1, A transfer unit 107 for transferring the artificial turf T separated from the ground by the iron refuse 105 to the crushing unit 109 and the artificial turf T transferred by the transfer unit 107 are crushed And a separator 111 for separating the filler T2 separated from the artificial turf T before crushing according to the components.

Therefore, when the artificial grass recoverer 101 starts to operate, the iron refuse 105 separates the artificial turf T constructed on the ground from the ground while the bogie 103 moves on the ground, Feeds the separated artificial turf (T) to the crushing section (109). The artificial turf T inserted into the crushing unit 109 is finely crushed to be the artificial turf chip TC while passing the filler between the cutters 113 in a state where the filler is separated immediately before the introduction, And then transferred to the melting machine 117 by the conveyor 115 and melted and stored. On the other hand, the filler separated from the artificial turf (T) before crushing is introduced into the separating part (111) and separated by weight.

However, since the filler is not completely separated from the artificial turf T prior to being introduced into the crushing unit 109, the synthetic turf collector 101 according to the related art does not completely separate the artificial turf chip TC, There is a problem that the purity of the artificial turf chip (TC) component melted in the artificial turf chip 117 significantly decreases.

The artificial turf T, that is, the grass carpet, which is fed into the crushing section 109, has different components depending on the site. For example, since the leaves are made of polyethylene and the back plate is made of polypropylene, There is a problem that the purity of the artificial turf chip (TC) component, which is melted in the water, is significantly lowered.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve the problems of the conventional artificial grass recovering machine as described above, and a series of artificial lawn collecting machines for separating, collecting, The objective of the present invention is to improve the performance of artificial grass recoverers by increasing the purity of artificial turf chips in the process of separation and crushing.

Particularly, the grass carpet constituting the body of the artificial turf is divided into two types according to the part, for example, the backboard is made of polypropylene and the leaf is made of polyethylene. The artificial turf chips are divided into two types Thereby improving the purity of the recovered artificial turf.

Further, another object of the present invention is to improve the efficiency of the artificial turf sorting work by making it easy to classify artificial turf chips by using the weight difference of each component.

 Another object of the present invention is to improve efficiency of post-processing such as collection and storage for recovery of artificial turf by melting and storing artificial turf chips classified by ingredients as described above.

Finally, before the artificial turf is crushed, the filling material is removed from the grass carpet by a separate device. Thereafter, the artificial turf chips classified through the crushing process are prevented from being mixed with the filling material, There is another purpose to doing this.

In order to achieve the above object, the present invention provides a railway vehicle comprising: An iron refuse installed on one side of the above-mentioned bogie to peel the artificial turf installed on the floor from the floor; A conveying unit for conveying the artificial turf separated from the floor by the iron refuse for crushing; A crushing unit for crushing the artificial grass transferred along the conveying unit; And a chip sorting unit for sorting the artificial turf chips crushed by the crushing unit according to the components.

In addition, the chip sorting portion may include: a channel means connected to one end of the crushing unit for discharging the artificial turf chips from the outlet; Conveying means for conveying the artificial turf chip installed on the outlet side of the channel means and discharged through the outlet; And a division vessel means connected to the other end of the conduit means and dividing the artificial turf chips transferred by the transfer means along the conduit means into two or more types.

In addition, the duct means may be an exhaust duct, the conveying means may be a blowing fan, and the dividing vessel means may be configured to receive a relatively heavy component of the artificial turf chips fed by the blowing fan along the exhaust duct, A first container positioned relatively close to the discharge side of the discharge duct; And a second container positioned relatively far from the discharge side of the discharge duct to receive a relatively lightweight component.

The artificial turf may further include a filler classifier disposed on a discharge side of the feeder and classifying the filler separated from the synthetic turf before the artificial turf is introduced into the crusher.

According to the artificial grass recovers of the present invention, since the filling material is completely removed from the artificial turf by the filler rejection before the artificial turf separated from the construction surface is introduced into the crushing section, the purity of the artificial turf chip crushed by the crushing section .

Further, the artificial turf chips crushed by the crushing parts are classified according to the components thereof and then melted individually by the respective chip melting means, so that the purity of the artificial turf chips to be melted and stored can be further increased.

Further, in sorting the artificial turf chips, the artificial turf chips are scattered and classified by using the weight that is different according to the components, so that the working efficiency according to the classification can be further improved.

In addition, since the artificial turf chips classified as above are immediately melted and stored on the truck, the efficiency of work for post-processing of the collected artificial turf can be greatly improved.

Of course, the artificial turf can be automatically separated from the construction surface to be crushed, the filler can be recovered from the artificial turf, the recovered filler can be classified according to the composition, and the crushed artificial turf chips can be melt- It is possible to improve the efficiency of the work related to the artificial grass collection as well as the work efficiency as well as the resource utilization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an artificial grass recovering apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The artificial grass recoverer according to the present invention comprises a main body 3, an iron refuse 5, a transfer portion 7, a crushing portion 9, and a chip sorting portion 9, as shown in FIG. 2 and FIG. 11, and further includes a filler classifier 13, a filler classifier vessel 15, and a filler rejection 17.

Here, the truck 3 is a part constituting the base of the artificial grass recoverer 1, and a plurality of rolling wheels 21 are mounted on the bottom surface, so that the artificial grass retriever 1 can move along the artificial turf Position to move to. 2 and 3, a driving engine 23 is mounted on the rear end of the bogie portion 3. The driving motor 23 is provided with a driving shaft 23 for driving the front wheel 21 or the rear wheel 21, And the drive engine 23 may be an internal combustion engine or a motor.

The iron refuse 5 is a tool part such as a screper which removes the artificial turf T installed on the floor and is attached to the front end of the bogie 3 so as to be adjacent to the floor as shown in Fig. And is inserted into the lower portion of the artificial grass according to the movement of the bogie portion 3 so that artificial turf attached to the floor is removed by the wedge action and is transferred to the transfer portion 7.

The conveying unit 7 is a part for conveying the artificial turf T separated from the floor by the iron refuse 5 to the crushing unit 9 as shown in FIG. (5). That is, the conveying section 7 is a conveyor provided obliquely on the conveying section 3, for example, a plurality of conveying rollers 25 aligned in a line toward the crushing section 9, a conveyor belt 27 surrounding the conveying roller 25 The artificial turf T coming up from the iron refuse 5 is sequentially transmitted to the crushing section 9 through the input line 33 in accordance with the rotation of the conveying roller 25. [ As shown in FIG. 4, each of the conveying rollers 25 has a plurality of protrusions 29 protruding from the outer circumferential surface thereof. The protrusions 29 are formed in an auger shape so that the artificial turf T is raised do. However, the feed roller 25 may be formed in the form of a sprocket or a toothed wheel in addition to the projections 29.

The crushing unit 9 crushes the artificial turf T and is disposed below the transporting unit 7 as shown in FIG. 2 and is a part of the artificial turf T transported along the transporting unit 7 The filling material T2 shown in Fig. 4 is removed and only the grass carpet T1 is crushed into a chip state. To this end, the crushing section 9 comprises a pair of cutting rolls 28, 29 and a feeding roll 30 which are interlocked with each other, as shown in Fig. At this time, the cutting roll 28 has a relatively large diameter as a main cutting edge and rotates counterclockwise, and the cutting roll 29 has a relatively small diameter as an auxiliary cutting tool and rotates clockwise. Since the cutting rolls 28 and 29 are provided with the cutting edges 31 in the form of a lattice on the respective cylindrical outer circumferential surfaces of the cutting rolls 28 and 29, Grind well. At this time, the feeding roll 30 rotates in the counterclockwise direction and serves to hold the lawn carpet T 1 between the cutting roll 29 and the cutting roll 29. However, the feeding roll 30 also has a cutting blade 31 in the form of a lattice so that the lawn carpet Tl can be largely cut along with the cutting roll 29.

The chip sorting section 11 is a sorter for sorting the artificial turf chips A and B pulverized by the grinding section 9 according to specific conditions such as a component. A conveying means 36, and a dividing container means 37, and may further comprise a chip melting means 43.

The duct means 35 is a tubular body such as a discharge duct for leading the artificial turf chips A and B pulverized in the crushing section 9 to the divided vessel means 37, One end is connected to the outlet 41 side of the upper grinding portion 9 and the other end is connected to the division vessel means 37. [ Therefore, the pipeline means 35 delivers the artificial turf chips A and B discharged from the crushing section 9 to the division vessel means 37 through the outlet 41.

The conveying means 36 is a conveying device such as a blowing fan for conveying the artificial turf chips A and B through the conduit means 35 as described above. The artificial turf chips A and B discharged from the crushing section 9 through the outlet 41 are pressed to the dividing container means 37 by strong winds. However, in the present embodiment, a blowing fan is used as the conveying means 36. However, in addition to the blowing fan, various other conveying devices such as a conveying screw may be used as the conveying means.

Finally, the dividing container means 37 is a container for classifying the artificial turf chips A and B together with the channel means 35 and the conveying means 36. As shown in FIG. 7, The artificial turf chips (A, B) are divided into two types according to the number to be sorted, that is, in this embodiment, they are accommodated. To this end, the dividing vessel means 37 is connected at its upper end to the other end of the conduit means 35 and is generally divided into a first vessel 371 and a second vessel 372.

Therefore, the artificial turf chips A and B discharged from the crushing section 9 are transported by the transporting means 36 along the channel means 35 to the divided container means 37. At this time, the turf carpet T1 of the artificial turf T has different components, i.e., different materials, from one site to another. That is, the lawn carpet T1 is largely classified into a backboard and a leaf. The backboard is made of polypropylene and the leaf is made of polyethylene. The artificial turf chips A and B crushed in the crushing section 9 are also relatively (A), in which the heavy backing is pulverized, and a polyethylene component (B), in which the leaves are relatively light in weight. Therefore, the artificial turf chips A and B, which are transported along the channel means 35 by the conveying means 36 such as a blowing fan, are arranged such that the heavy component A sinks first and is discharged from the discharge side of the channel means 35 The light component B is accommodated in the second container 372 relatively far from the discharge side of the channel means 35 and is naturally classified into components by being housed in the relatively near first container 371 .

The chip sorting unit 11 can store the artificial turf chips A and B divided and housed in the first and second containers 371 and 372 as they are, It is more advantageous in terms of miniaturization. To this end, the chip sorting section 11 may further include a chip melting means 43, which is connected to the first and second containers 371 and 372, respectively, And the artificial turf chips A and B accommodated in the containers 371 and 372 are separately supplied through the conveyor 45 and the like. That is, the chip melting means 43 is divided into partition walls or the like, and the artificial turf chips A and B accommodated in the respective containers 371 and 372 are separately collected and melted.

The filler classifying portion 11 is a portion for classifying the filler T2 by the component, that is, by the size of the particle of the filler T2, and is provided on the discharge side of the transfer portion 7 as shown in FIG. The filler T2 separated from the artificial turf T is sorted before putting the grass T into the crushing section 9. [

6 and 7, the filling material sorting section 11 includes a plurality of diaphragms 51, a vibrator 53, a collecting table 55, and a hopper 57 as shown in FIGS.

Here, the plurality of diaphragms 51 is a chute of a laminated structure continuously provided at a gentle inclination angle. As shown in Figs. 6 and 7, when each diaphragm 51 is inclined They are stacked in a zigzag manner. The filler T2 dropped from the artificial turf T on the outside of the diaphragm 51 is discharged to the upper end of the uppermost diaphragm 51 at the discharge side of the transfer section 7. The charged filler T2 thus slid from the uppermost diaphragm 51 by its own weight and falls and moves to the diaphragm 51 under the lower one of the chambers and then falls at the lower end of the lowermost diaphragm 51 . In the case of this embodiment, as shown in Fig.

6, the vibrator 53 vibrates the diaphragm 51 to smoothly move the filling material T2 more smoothly. The vibrator 53 is disposed in the case of the filling material separator 13 The entire diaphragm 51 can be vibrated with one of the diaphragms 51 attached thereto, or the diaphragm 51 can be separately vibrated by attaching the diaphragm 51 separately. At this time, the vibration applied to the diaphragm 51 not only promotes the sliding movement of the filler T2 as described above, but also the filler component C, which is relatively dense and heavy in the filler T2, ) And the filler component (D), such as a lightweight rubber chip having a relatively low density, is placed on the filler component (C), so that the filler (T2) is first classified according to the density difference.

The collecting table 55 is a means for separating a part of the filler T2 on the diaphragm 51. As shown in Figs. 6 and 7, on the diaphragm 51, . Therefore, the collecting table 55 picks up the light filler component D that has been lifted up due to the difference in density among the fillers T2 moving downward along the diaphragm 51. At this time, the collecting table 55 is inclined toward the hopper 57 even when viewed in a plan view as shown in Fig. 7, thereby facilitating the discharge of the filler component D.

Finally, the hopper 57 is a conduit means for discharging the low-density filler component D filtered by the collecting table 55 to the outside of the diaphragm 51. As shown in FIGS. 6 and 7, 51) adjacent to the collecting table (55). Particularly, a charging pipe 59 is connected to the lower end of the collecting table 55 to discharge the filling material D from the entire diaphragm 51 at the same time.

The filling material sorting container 15 is a container means for finally sorting and storing the filling material T2 that has passed through the upper stuffing material sorting portion 13. As shown in Fig. 6, the blowing fan 61, the receiving plate 63 ), And a recovery cylinder 65.

6, the blowing fan 61 is an air blowing means for blowing the filler T2 falling from the filler sorting portion 13 by air pressure, and is disposed adjacent to the filler T2 inlet 66 And the filler (T2) flowing through the inlet (66) is scattered and finally classified by using the scattering distance depending on the weight difference.

The receiving plate 63 is a portion for making a place where the filler T2 scattered by the blowing fan 61 can sink down. As shown in FIG. 6, the filling plate T2 And further includes a first discharge port 67, a second discharge port 68, and a plate body 69. The first discharge port 67, the second discharge port 68,

Here, the first discharge port 41 is a hole through which the relatively heavy component C is discharged from the filler T2 injected through the charging port 66, and the filler component C is the hole A part thereof is almost not scattered by the blowing fan 61 and falls downwardly and is received in the recovery cylinder 65 through the first discharge port 41. [ And the remaining part is widely dispersed on the plate body 69 while varying the scattering distance in accordance with the weight difference of itself. At this time, the first discharge port 41 is arranged on the same line as the charging port 66 so as to pass the non-scattered filler component C.

On the contrary, the second discharge port 41 is a hole through which the relatively lightest component D is injected from the filler T2 injected from the charging port 66, and the filler component D is, as shown in FIG. 6, And the air is blown by the blowing fan 61 and mostly scattered to the second discharge port 41. However, the component having a heavy weight is dropped to the front of the second discharge port 41. [ At this time, the filler component (D) scattered by the second discharge port (41) is accommodated in the recovery cylinder (65) while being separated from the filler component (C).

Finally, the plate 69 is a body of a receiving plate 63 disposed between the first discharge port 41 and the second discharge port 41. The plate body 69 is made of a filler material injected into the filling material container 15 through the inlet port 66, (65) through the first and second ejection openings (41) due to a moderate weight such as a relatively heavy component (C) and a relatively lightweight component (D) And receives the remaining filler (T2). At this time, the plate body 69 has, for example, two steps 71 as shown, so that the filler T2 can be more clearly separated by components according to the scattering distance difference by the stepped portion 71.

The filler rejection 17 is a portion for separating the filler T2 from the artificial turf T before being input into the artificial turf T grinding unit 9, 13) adjacent to the discharge side of the transfer section (7). Accordingly, the filler rejection 17 is preferably made in the form of a cylindrical rotatable brush 73 as shown in the figure so that the granular filler T2 sandwiched between the leaves of the artificial turf T can be easily removed . More preferably, as shown in the drawing, the air nozzle 74 is provided so as to face the contact area between the brush 73 and the artificial turf T, so that the filling material T2 can be more smoothly separated by the high-pressure air.

Now, the operation of the artificial grass recoverer 1 according to the preferred embodiment of the present invention will be described as follows.

When the artificial turf collector 1 is operated to recover the artificial turf T of the present invention, the artificial turf collector 1 moves the artificial turf T, which moves along the ground by the cart 3, And is detached from the ground by the iron refuse 5 as shown in Fig.

2, the artificial turf T is lifted by the conveyor belt 27 or the like of the conveying unit 7 and is conveyed by the brush 73 and the air nozzle 74 at the discharge side of the conveying unit 7, That is, the filler components (C, D) sandwiched between the leaves, into the filler classifying portion 13 on the input side. The filling material T2 is separated and the remaining grass carpet T1 is transferred to the crushing section 9 through the input line 33. [

The grass carpet T1 transferred to the crushing section 9 is introduced into the crushing section 9 and passes through the cutting rolls 28 and 29 shown in FIG. B), and is introduced into the conduit means 35 through the outlet 41. [0064] The artificial turf chips A and B introduced into the channel means 35 are conveyed to the chip sorting portion 11 by the conveying means 36 such as a blowing fan.

For example, the artificial turf chips A and B transferred to the chip sorting portion 11 in a scattered manner are transferred to the first container 371 and the second container 372 in accordance with the components of the chips A and B, ) To classify the same or similar components. The artificial turf chips A and B thus classified are put into the chip melting means 43 through the conveyor 45 and the like, and then the same or similar components are gathered and melted together.

On the other hand, the filler T2 separated from the artificial turf T by the filler rejection 17 at the discharge side of the transfer part 7 is introduced into the filler classifying part 13 as shown in Figs. 2 and 6 . The filling material T2 injected into the filling material sorting part 13 moves downward along the diaphragm 51 by vibration. At this time, the component (C) having a relatively high density, that is, the heavy component (C) of the filler (T2) is laid down and the component (D) having a relatively low density, that is, a light component, Therefore, the upper component C that meets the collecting table 55 is discharged through the hopper 57 to the outside of the packing member 13 and classified.

As described above, the lightweight component D in the filler T2 is discharged and classified to a large extent through the diaphragm 51. At this time, the remaining unclassified component D is finally classified when the filler T2 is introduced into the filler-containing container 15, and the filler T2 injected into the filler-containing container 15 through the filler- Most of the heavy components C are almost not scattered but are mostly received in the recovery cylinder 65 through the first discharge port 67 of the receiving plate 63 and only a part And is distributed widely on the plate 69 of the receiving plate 63. On the other hand, the minimum component (D) remaining in the filler (T2) is introduced into the recovery container (65) through the second discharge port (41) of the receiving plate (63) Only a part thereof is stacked in front of the second discharge port 41. [

The filler T2 accommodated in the recovery cylinder 65 is divided by the partition 75 so that the separation into the two components C and D is completed. The suction fan 19 installed in the case of the filling material sorting vessel 15 in opposition to the blowing fan 61 sucks dust and the like generated by the blowing fan 61 and passes the dust to the water tank 77, (1) Various dusts generated in the filling material sorting container (15) are removed during operation.
