In general, artificial turf is artificially formed to have a grass shape by using synthetic fiber as a material, and it is used in soccer field, field hockey field, various indoor interior and leisure facilities because it is easy to manage after construction and is always maintained in green.

Generally, artificial turf includes a carpet type substrate, a grass layer formed on the substrate and having a grass shape, and a filler filled in the grass layer.

The substrate and grass layer are fabricated using thermoplastic chemical fibers as a fibrous structure, wherein the filler comprises a particulate silica sand and an elastic body such as rubber or silicone particles.

Such artificial turf is inevitably replaced due to its longevity due to abrasion and the like after a few years after construction. Accordingly, a method of separating the substrate made of the thermoplastic chemical fiber, the grass layer, and the filler to recycle the artificial turf has been disclosed. Since the separated base material and grass layer are made of chemical fiber, they can be recycled by using heat or the like.

However, in the case of the filler material made of the silica sand and the elastic body, there is a problem that it is difficult to separate the silica sand and the elastic body because they are fine particles even if the particle sizes of the silica sand and the elastic body are different from each other. Further, even if the diatomaceous earth and the elastic body are separated, there is a problem that they are difficult to be recycled unless they are completely separated from each other.

Accordingly, an object of the present invention is to provide a sorting system and a sorting method for recycling fillings, each of which can be separated so as to have a purity of 99% or more, for recycling of a filler material in which at least two materials are mixed.

The primary sorting apparatus includes a trommel screen or a vibrating screen.

The second sorting apparatus has a predetermined inclination, the second material having a relatively large specific gravity among the at least two materials has a high inclination, and the first material having a relatively small specific gravity has a low inclination Spiral classifier.

The second sorting apparatus further includes a pressure water supply unit for supplying pressure water so that the second material floats at a position where the inclination of the spiral classifier is low.

The second sorting apparatus further includes a discharge guide for guiding the discharge of the second substance suspended by the pressure water.

The at least two materials include silica sand and an elastic body.

This object is solved according to the present invention by a first sorting step of sorting at least two materials on the basis of a particle size, in a sorting method for recycling a filler material in which at least two materials are mixed; And a second sorting step of sorting at least two materials having a particle size falling within a predetermined range after the primary sorting based on the specific gravity.

The first sorting step includes a step of sieving the first material having a size larger than a predetermined particle size and sorting the first material.

The second sorting step is performed by a spiral classifier having a predetermined inclination, and the second material having a relatively large specific gravity of the at least two materials is a position having a high inclination, and the first material having a relatively small specific gravity has a slope To a low position.

The second sorting step further comprises the step of providing a pressure number such that the second material floats at the lower slope.

The second sorting step further includes discharging the second material suspended by the pressure water through the discharge guide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 1 is a flowchart of a sorting method for recycling fillers according to an embodiment of the present invention.

The sorting method for recycling a filler material according to an embodiment of the present invention includes a first sorting step (S110) of sorting at least two materials on the basis of particle size, And a second sorting step (S120) of sorting at least two materials based on the specific gravity. The first sorting step will be described in more detail with reference to FIG. 2 and FIG. 3, and the second sorting step will be described in detail with reference to FIG.

The recycling method for recycling the filler material according to an embodiment of the present invention may be such that the purity of each of the two materials is 99% or more so as to recycle the filler material in which at least two materials are mixed. Particularly, the sorting method for the recycling of the filler material is effective for separating the mixed materials in which the specific gravity is different but at least two materials which can be easily separated because the difference in particle size is not large.

Here, the at least two materials may have different specific gravity ranges. For example, the first material may comprise a material having a specific gravity between 1 and 2, preferably between 1 and 1.7, and the second material may have a specific gravity between 2 and 3, preferably between 2.2 and 2.6 Lt; RTI ID = 0.0 > a < / RTI > The at least two materials may have different particle size content ratios. For example, the first material may have a particle size between 0.01 mm and 3 mm, among which the particle size between 1 and 3 mm may be included in the largest proportion, and the second material may also be between 0.01 mm and 3 mm Size, and among them, the particle size between 0.1 and 0.9 mm can be included in the largest proportion.

Particularly, the method for recycling filler material according to an embodiment of the present invention is characterized in that, in order to recycle a filler material mixed with at least two materials, which is filled when artificial turf is applied, And the filler material may include silica sand and an elastic body. The elastic body may include a rubber chip or silicone, and the specific gravity may have a value between 1 and 2, preferably between 1 and 1.7. The sandpaper may have a specific gravity of between 2 and 3, preferably between 2.2 and 2.6. According to the sorting method for recycling the filler material according to the present invention, each of the silica sand and the elastic body can be separated so as to have a purity of 99% or more, so that it is very easy to recycle each of the silica sand and the elastic body.

The first sorting step S110 according to an embodiment of the present invention is performed by the first sorting apparatus 100 shown in FIG. 2 and FIG.

The first sorting apparatus 100 can sort the first material and the second material based on the particle size. For example, as described above, the content ratio according to the particle size of the first material may include the largest particle size between 1 and 3 mm, and may include various particle sizes sequentially. Likewise, the content ratio of the second material with respect to the particle size may be in the range of 0.1 to 0.9 mm in the largest proportion, and may be sequentially contained in various particle sizes. Here, the first sorting apparatus 100 may sort only the substance having the particle size of between 1 and 3 mm included in the largest proportion of the first substance to about 1 to 40% for the entire first substance, And about 10 to 30% of the total amount. Accordingly, the first sorting apparatus 100 may include a screen capable of squeezing the size of the particle size of 1 to 3 mm or more. Accordingly, the first sorting apparatus 100 according to the present invention may include any type of apparatus as long as it includes a screen capable of squeezing a size larger than a predetermined size. That is, the first sorting apparatus 100 may include a screen capable of sieving a substance having the largest particle size range among the fillers. For example, the primary sorting apparatus 100 may include a trommel screen apparatus or a vibrating screen apparatus.

The first sorting apparatus 100 can sort the materials having the largest particle size range among the at least two materials included in the filler by dry or wet method. Preferably, the first sorting apparatus 100 can be selected by a dry method.

Therefore, the first sorting apparatus 100 can sort the first material at a predetermined ratio. When the first sorting is completed, the remaining first and second materials are mixed and present.

The mixture is subjected to the second screening step (S120). The mixture has a particle size falling within a predetermined range according to the first sorting. That is, the first material having a particle size of 1 to 3 mm or more is separated through the primary sorting so that the range of the particle size of the first material is similar to that of the second material. Accordingly, the second sorting step S120 may separate the first material and the second material based on the specific gravity.

The first sorting step S110 according to an embodiment of the present invention is performed by the first sorting apparatus 100 shown in FIG. 2 and FIG. Here, the first sorting apparatus 100 is exemplified as a trommel screen apparatus, but can also be performed by a vibration screen apparatus.

The first sorting apparatus 100 includes a screen 111, a filtrate storage unit 113, and a rotation unit 115.

The screen 111 includes a plurality of screening holes 117 capable of screening a size larger than a predetermined particle size, and the screen 111 shown in FIGS. 1 and 2 shows a trommel screen as one embodiment have. Any type of screen may be included as long as it is capable of separating a material having a size greater than or equal to a predetermined particle size according to the intention of the present invention.

The size of the predetermined size or larger refers to a size range of the largest size among the fillers including at least two materials that flow into the screen of the first sorting apparatus 100. For example, as illustrated in FIG. 1, the filler may have a particle size between 0.01 mm and 3 mm, the first material having a particle size between 1 and 3 mm in the largest proportion; The first material may have a particle size of between 0.01 mm and 3 mm, and when the first material includes a second material having a particle size between 0.1 and 0.9 mm in the largest proportion, The sorting hole 117 may have a size such that materials having a particle size of less than 1 mm are passed therethrough in order to select only a substance having a particle size of between 3 mm and 3 mm.

Therefore, the first material 10 having a particle size of 1 mm or more, which can not pass through the first hole 117 of the first material among the fillers introduced into the first sorting apparatus 100, And the remaining first material and second material 20 having a particle size of less than 1 mm that has passed through the sorting hole 117 can be accommodated in the following filter material receiving portion 113. [ The size of the sorting hole 117 can be adjusted corresponding to the particle size of the materials included in the filler, and the numerical values of the particle size described above are only examples for explaining the present invention in detail.

The rotating part 115 applies a rotational force to the screen 111 to rotate the screen so that the first material and / or the second material is sieved according to the size of the sorting hole 117.

The first sorting apparatus 100 may be configured to sort out the first material having a particle size larger than the sorting hole size among the first materials and the second substance among the first materials included in the filler by about 1 to 40 %, Preferably about 20 to 30%, of the total weight of the composition.

If the first material having a particle size that can not be passed through the sorting hole 117 is selected at a predetermined ratio, the remaining first material and second material are transferred to the second sorting apparatus 200.

Although the first sorting apparatus 100 shown in FIGS. 2 and 3 shows an embodiment in which materials are separated according to the particle size by a dry method, the present invention is not limited to the present invention, The device 100 may also be a wet process.

The second sorting step S120 according to an embodiment of the present invention is performed by the second sorting apparatus 200 shown in FIG.

The second sorting apparatus 200 includes a housing 210, a spiral classifier 220, a pressure receiving unit 230, and a discharge guide 240.

The housing 210 may have a long tank shape having a predetermined inclination or an upper portion of the tank shape may be exposed. The housing 210 includes a first discharge portion 211 at a high inclination and a second discharge portion 213 at a low inclination.

The spiral classifier 220 is accommodated in the housing 210 and has an inclination substantially equal to or similar to that of the housing 210. The spiral classifier 220 rotates while the material having a relatively high specific gravity is discharged from the first discharge portion 210. [ As shown in FIG. Accordingly, the second material having a relatively high specific gravity is moved to the portion having a high degree of inclination by the spiral classifier 220, and eventually discharged through the first discharge portion 211.

The first material and the second material located at the lower inclined portion of the housing through the spiral classifier 220 are stirred together when water is present in the water provided by the pressure water treatment unit 230 The second material having a relatively high specific gravity is transferred to the upper portion of the spiral classifier 220 so that the first material having a relatively low specific gravity can float above the water surface.

The pressure water supply unit 230 is located below the housing 210 to provide pressure water and supplies the pressure of the pressure supplied by the pressure water supply unit 230 at a low inclination position of the spiral classifier 220 Can be locked by the number. The first material having a relatively low specific gravity stays at a lower portion of the spiral classifier 220, that is, at a lower inclination. The pressure water provided by the pressure water treatment unit 230 is directed toward the advancing direction of the spiral classifier 220 (For example, the pressure water is provided in a direction opposite to the gravity direction), and the first material having a relatively low specific gravity by the provided pressure number floats in water And almost all of the first material having a relatively low specific gravity can float on the water due to the pressure of the provided pressure water. The effect of selecting the specific gravity of the two materials separated according to the specific gravity by the spiral classifier 220 can be maximized by the pressure water handler 230 so that the effect of sorting can be more excellent.

The discharge guide 240 may guide the discharge of the first substance floating by the pressure water. The discharge guide 240 is provided to suck the floating first material or to guide the water on the upper part of the pressure water to flow toward the second discharge part 213, The first material can be relatively easily discharged to the second discharge portion 213 and can be sorted.

Accordingly, according to an embodiment of the present invention, the first material and the second material are separated so as to have a purity of 99% or more, respectively, while passing through the first to second sorting steps, Each of the materials can be recycled for a desired purpose.

Although several embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various modifications may be made without departing from the principles and spirit of the invention . The scope of the invention will be determined by the appended claims and their equivalents.
