The present application relates to an apparatus for filtration and separation of plastic particles in sand and a method for filtration and separation of plastic particles using the same.

Large-sized plastic waste can be collected by manpower or cleaning equipment, but so-called fine plastics, which have a size slightly larger than the main particle size of sand, are difficult to collect and decompose into numerous smaller particles through weathering. And has an adverse effect on the ecosystem.

However, since the previously developed beach cleaning equipment was developed to collect relatively large general garbage, the vibrating sieve plate receives sand near the surface and the garbage is thrown up on the slope to collect it.

It is disposed, and may be provided to receive vibration applied by the excitation unit.

In the absence of the sieve plate lower guide, some of the particles to be dropped on the front region of the lower sieve plate may be moved rearward by the sieve plate lower guide, thereby being dropped into the rear region relatively rearward than the front region of the lower sieve plate.

The plastic particle filtration separating apparatus includes: a perforated plate disposed at an upwardly spaced distance from an uppermost sieve plate positioned at an uppermost side of the plurality of sieve plates and having a plurality of perforated holes; And disposed at an upward interval with the perforated plate to cover the top of the perforated plate, and a partial area is opened so that the particles mined and transported by the mining unit and then dropped downward can reach the perforated plate to form an inlet.

It is to filter.

The plastic particle filtration and separation apparatus according to an embodiment of the present application may be used to purify the pollution of a sand bar in a river/shore in which fine plastic is accumulated. In addition, since the filtered plastics are separated and stored through an automated process, they can be used in environmental science research investigating the degree of contamination of fine plastics, and thus can be used to build an extensive database.

Hereinafter, a plastic particle filtration separation apparatus (hereinafter referred to as “the apparatus”) according to an embodiment of the present disclosure will be described.

1A is a three-dimensional conceptual diagram showing the overall structure of a plastic particle filtration separation apparatus according to an embodiment of the present application, and FIG. 1B is a conceptual diagram showing a state viewed from a side of a plastic particle filtration separation apparatus according to an embodiment of the present application.

The apparatus 100 includes a mining section 1 and a sieve section 2.

The mining unit 1 mines particles including at least one of sand particles and plastic particles and transports them upward.

As described above, the device 100 may be applied to a sand bar formed on a river/shore or the like. Accordingly, the mining unit 1 mines sand, but when some plastic particles other than sand are included in the mining area, plastic particles included together may also be mined.

In addition, referring to FIGS. 1A and 1B, the mining unit 1 may transfer particles mined from the sand ground on which the sandbar or the like is formed to the upper side of the sieve unit 2. Referring to Figure 1a, the mining unit (1) can be introduced into the sieve plate (2) through the open space (inlet) on the upper side of the sieve plate (2) with the particles transported above the sieve plate (2). have.

The mining unit 1 may include a chain belt 12 rotated by a pair of chain gears.

Illustratively, referring to FIGS. 1A and 1B, a pair of chain gears are arranged at mutual intervals, and a chain belt 12 is a pair of chains in a form surrounding a part of the outer periphery of each of the pair of chain gears. Can be installed against the gear. For example, the chain belt 12 may be installed in a track type. Accordingly, when the chain gear is rotationally driven, the chain belt 12 installed with respect to the chain gear can be moved while being rotated in a form that maintains a track shape in association with the rotation of the chain gear.

Illustratively, referring to FIG. 1B, the distance between a pair of chain gears is that the chain gear on the front side (at 9 o'clock in FIG. 1B) is higher than the sieve plate 2 (for example, the sieve plate 2 is upward). The chain gear located on the upper side of the opening inlet) and on the rear side (at 3 o'clock direction based on FIG. 1B) may be set to form an obliquely inclined distance from the front to the rear so as to be close to the ground. By setting such an interval, a mining operation for particles formed on the ground, such as sand, may be performed according to the movement in conjunction with the chain belt 12 of the bucket 11 to be described later. In addition, the speed at which the chain belt 12 is rotated by a pair of chain gears is a speed at which an overload is not applied when the plurality of buckets 11 repeatedly pumps sand contained in the ground and a sieve plate ( It is desirable to set it in consideration of the speed at which mining can be performed to the extent that the filtration operation in 2) can be performed normally.

In addition, the mining unit 1 may include a plurality of buckets 11 installed at intervals along the circumferential direction with respect to the belt outer circumferential surface of the chain belt 12 so as to move in conjunction with the rotation of the chain belt 12. have. For reference, the bucket 11 may be understood as a configuration that is the same or similar to a configuration installed for equipment such as a crane or a crane as a configuration in the form of a bucket, bucket, pail, etc. that pumps sand, etc. .

1A and 1B, the chain belt 12 is rotated by a pair of chain gears, so that a plurality of buckets 11 containing particles mined from the ground are sequentially moved upwards of the device 100. In addition, an operation of pumping up particles such as sand from the ground may be repeatedly performed through the sequential movement of the plurality of buckets 11 in the form of circulation. In addition, the bucket 11, which has completed the mining operation of pumping particles, moves the chain belt 12 upwards in conjunction with the belt movement, and rotates along the outer circumference of the chain gear located on the front upper side, while the inner bottom surface touches the ground. The direction is switched so that the mined particles can be dropped downward toward the sieve portion 2.

The interval between the plurality of buckets 11 is that when the bucket 11 reaches the sieve plate 2 and puts the mined particles into the sieve plate 2, the mined particles are moved before the input is completed. It is preferable that the bucket 11 is set to such an extent that interference with the input of particles can be prevented. In other words, when continuous mining by a plurality of buckets 11 is sequentially circulated, the interval between the buckets 11 is set so that the input of the mining particles in the subsequent bucket 11 is not disturbed by the previous bucket 11 Can be. As a specific example, referring to FIG. 1B, when any one of the plurality of buckets 11 moves on the outer circumference side of the outer circumference of the chain gear on the front upper side, which is completely opposite to the chain gear on the rear and lower side, the bucket 11 or the subsequent bucket 11 or Prior to that, a distance between the buckets 11 and the buckets 11 may be set at an interval of approximately 90 degrees.

In addition, in mining sand from the ground on which sand deposits such as rivers/shores are formed, for example, the mining depth into which the bucket 11 is inserted inside the surface (inside the ground) such as a sand bar may be set to approximately 10 cm or more. However, it is not limited thereto.

In addition, the bucket 11 may be formed of a durable material so as not to be worn or damaged even if particles are repeatedly mined for a long period of time. In addition, the size of the bucket 11, taking into account the amount of particles that can be accommodated in the bucket when one bucket 11 is mined once, is the speed of the belt movement (rotation) of the chain belt 12, and the It can be set in consideration of the filtration performance and the conditions of on-site mining, such as the condition of the ground including sand.

1A and 1B, the chain belt 12 has a downward tilt angle at which particles can be mined by the bucket 11 and an upward lift angle that does not interfere with the ground in a state in which the bucket 11 contains particles. It may be provided to be rotated in the included angular range.

For example, FIG. 1B may exemplarily show an upward lifting angle in which the bucket 11 does not interfere with the ground. In the angular state of FIG. 1B, when the rear side of the chain belt 12 (at 3 o'clock direction of FIG. 1B) is inclined downward, the bucket 11 located at the rear side of the chain belt 12 may contact the ground. In addition, if the downward tilt angle is adjusted in consideration of the state of sand in a corresponding region (area), an appropriate angle at which particles such as sand can be mined by the bucket 11 may be set. For example, when performing the mining and filtering process by the device 100, a downward tilt angle may be set on the chain belt 12, and when moving to another place (area) after completing the mining and filtering process, the bucket An upward lifting angle may be set on the chain belt 12 to avoid interference between (11) and the ground. In addition, in consideration of the ground condition and the working condition, the downward tilt angle and the upward lift angle of the chain belt 12 are more closely adjusted so that the work can be smoothly performed in response to various working environments.

1A and 1B, the adjustment of the downward tilting angle and the upward lifting angle of the chain belt 12 may be performed by the driving unit 13 and a plurality of link members hinged to the driving unit 13. have. In addition, the driving unit 13 may be a driving unit that expands and contracts linearly. For example, the drive unit 13 may be a linear actuator such as a hydraulic cylinder or a pneumatic cylinder. The drive unit 13 is indirectly connected to the chain belt 12 through a plurality of link members, and tilts the chain belt 12 downward or upward according to the linear drive amount (movement amount) of the drive unit 13. You can raise it. As a specific example, referring to FIG. 1B, the driving unit 13 has its front end hinged to the upper front end of the sieve plate 2 (for example, the upper front end of the closed frame), and the rear end of each of the two link members It can be installed in a form that is hinged to the top. In addition, the lower end of one of the two link members may be hingedly connected with respect to the rotational axis of the chain gear on the front upper side, and the lower end of the other of the two link members may be hingedly connected at an intermediate position between the pair of chain gears. For the structure in which the driving unit 13 and the link member are combined, the driving unit 13 is linearly driven, so that the rear end of the chain belt 12 is lifted upward or lowered downward. ) Angle control can be performed.

Figure 2 is an exemplary configuration of a sieve plate configuration, a sieve plate lower guide configuration, an excitation unit configuration, a storage unit configuration, a perforated plate configuration, a cover configuration, a mining unit configuration, an angle adjusting device configuration, etc. in the plastic particle filtration separation device according to an embodiment of the present application It is a schematic side perspective conceptual diagram for explaining, and FIG. 3 is a sieve plate configuration, a sieve plate lower guide configuration, an excitation unit configuration, a storage unit configuration, a perforated plate configuration, a cover configuration, and the like of the plastic particle filtration separation device according to an embodiment of the present application. It is a schematic cross-sectional view for illustrative purposes, and FIG. 4A is an exemplary conceptual diagram for explaining particle filtration using a plastic particle filtration separation device according to an embodiment of the present application, and FIG. 4B is a plastic according to an embodiment of the present application. It is a conceptual diagram for illustratively explaining a sieve plate configuration, a sieve plate lower guide configuration, an excitation unit configuration, and a storage unit configuration of the particle filtration separation device.

1A, 1B, and 2 to 4, the sieve unit 2 is a plurality of sieve plates disposed at vertical intervals so as to sequentially filter particles that are mined and transported by the mining unit 1 and then dropped downward. It includes a sieve plate 21 of.

Here, the particles falling downward on the sieve plate part 2 are particles that are dropped directly downward on the sieve plate part 2 or particles that are dropped downward onto the sieve plate part 2 after passing through the perforated plate 3 to be described later. I can.

In addition, sequential filtering of downwardly dropped particles means that the particles that are mined and transported and then dropped downward are filtered through a sieve plate located at a relatively upper side of the plurality of sieve plates 12, and then again at a sieve plate located at the lower side. It may mean that the filtering process is performed sequentially.

In addition, the sieve plate 21 may be a plate-shaped member in which a plurality of sieves are formed. As an example, the plurality of body eyes may have a rectangular shape, but are not limited thereto. In addition, the plurality of body eyes may be formed in a grid shape that is repeatedly arranged in the front-rear direction and the transverse direction, but is not limited thereto.

In addition, in the plurality of sieve plates 21, since the sieve plate itself is a structure including a plurality of sieves, it may be somewhat more susceptible to bending than a solid (closed) plate material in which the plurality of sieves are not formed. A reinforcing frame capable of supplementing fragility may be installed at least in part on an edge portion of the plurality of sieve plates 21.

In addition, referring to the drawings, the plurality of sieve plates 21 may be two, but is not limited thereto. For example, when a plurality of sieve plates 21 are used to classify plastic particles to be filtered into more than two grades per particle size, three or more sieve plates 21 may be provided. have.

In addition, a plurality of sieve plates 21 may be disposed parallel to each other. Illustratively, referring to FIGS. 1B and 3, a plurality of sieve plates 21 are disposed to be inclined downward in the front (9 o'clock direction based on FIGS. 1B and 3 ), but may be disposed parallel to each other, but are limited thereto. no. As another example, the downward slope of each of the plurality of sieve plates 21 may be set differently from each other in a line that does not interfere with each other or impair each filtration performance.

Referring to the enlarged view of FIG. 3 and FIG. 4, the plurality of sieve plates 21 may be provided so as to have a smaller sieve size as the sieve plates are located at a relatively lower side.

Exemplarily, referring to the enlarged view of FIG. 3, the size of the sieve plate located at a relatively lower side of the plurality of sieve plates 21 than the size (a) of the sieve plate positioned at the upper side of the plurality of sieve plates 21 ( b) may be smaller. Accordingly, larger particles (large plastic particles) can be filtered out of the sieve plates located relatively above among the plurality of sieve plates 21, and smaller particles (small plastic particles) can be filtered in the sieve plates located relatively lower.

The sieve size of the lowermost sieve plate located at the bottom of the plurality of sieve plates 21 is set larger than the size of the sand particles, but may be set smaller than the size of the plastic particles desired to be filtered. For example, the sieve size of the lowermost sieve plate may be approximately 1 mm, but is not limited thereto, and it is preferable that the sieve size is set smaller than the size of the minimum plastic particles desired for final filtering. For example, when the size of the minimum plastic particles targeted for filtration is 2 mm, the sieve size of the lowermost sieve plate may be set to a size slightly smaller than 2 mm. In addition, the sieve plate disposed on the upper side relative to the lowermost sieve plate may have a larger sieve size than the bottom sieve plate. As an example, the sieve size of the uppermost sieve plate may be approximately 5 mm, but is not limited thereto, and it is preferable to set in consideration of the size of the largest plastic particle desired for initial filtration. For example, if a plastic particle exceeding a maximum of 3 mm is selected and classified, the sieve size of the top sieve plate may be set to 3 mm or less.

In addition, the sieve plate portion 2 may be provided such that particles passing through the lowermost sieve plate fall to the ground. For example, referring to FIGS. 1A and 2, the sieve plate portion 2 may be provided such that the lower side of the lowermost sieve plate is opened downward. In order to form the sieve plate portion 2 that is opened downward, a closing frame may be provided in a form in which the upper and lower portions of the sieve plate portion 2 are opened and only the circumferential side of the sieve plate portion 2 in the horizontal direction is closed.

In addition, the fact that the sieve size of the lowermost sieve plate is set to be smaller than the size of the plastic particles desired to be filtered means that the plastic particles that are larger than the sieve size of the lower sieve panel among the plastic particles input on the plurality of sieve plates 21 are selectively filtered. It can mean.

Referring to FIGS. 2 to 5, each of the plurality of sieve plates 21 may be disposed inclined downwardly inclined in a forward direction (9 o'clock based on FIGS. 2 to 5 ). Here, the downward slope toward the front may mean that a slope that is downhill toward the front is formed.

In addition, the inclination angle at which each of the plurality of sieve plates 21 is inclined is linked with the vibration strength of the vibrating unit 22 to be described later, and particles injected into each of the sieve plates 21 are vibrated by the vibration of the vibrating unit 22. The process of selectively filtering and gradually moving to the storage unit 23 may be set in consideration of an angle that can be time-efficiently and an angle that can be efficiently filtered. For example, if the inclination angle of the sieve plate 21 is formed too large, the time that the particles stay on the plurality of sieve plates 21 becomes short, so that the filtering function may not be sufficiently performed, and the inclination of the sieve plate 21 When the angle is formed too small, the particles cannot move forward despite the excitation of the excitation unit 22 and accumulate on the plurality of sieve plates 21, so that the filtering function may not be sufficiently performed. In consideration of these points, the inclination angle of the sieve plate 21 is set to an appropriate inclination angle that allows the particles to sufficiently stay on the sieve plates 21 and undergo a filtration process, but the filtration can proceed without accumulation. desirable.

Referring to FIGS. 2 and 3, in particular, an enlarged view of FIG. 2, the sieve plate unit 2 may include a vibration unit 22 that applies vibration to the plurality of sieve plates 21.

The vibrating unit 22 may be provided to apply vibration to the plurality of sieve plates 21 to move the particles present on the plurality of sieve plates 21 forward along a downward inclined surface.

In addition, in order to install the excitation unit 22, a hinge and a bracket may be provided for fixing the excitation unit 22 with respect to the frame provided on the rim of the plurality of sieve plates 21.

The excitation unit 22 may be provided to transmit vibrations in the form of periodic impulses to the plurality of sieve plates 21. Referring to the enlarged view of FIG. 2, the excitation unit 22 may include a cam having at least one or more noses, and a rotation driving unit that rotates the cam. The cam may be disposed under the sieve plate 21 to which vibration is to be applied or the perforated plate 3 to be described later. In Figure 2, the excitation unit 22 is shown to be provided on both the front lower side and the rear end of the sieve plate 21 or the perforated plate 3, but is not limited thereto, and the sieve plate 21 or the perforated plate 3 It may be provided in an appropriate number in various locations for effective excitation. For example, it may be more effective in terms of efficiency to have the excitation unit 22 disposed on the upper side of the rear end (upper side of the slope) rather than the lower front side (lower side of the slope) of the sieve plate 21 or the perforated plate 3. It is not limited only. On the other hand, when the cam type is applied as an example of the excitation unit 22, for example, as shown in FIG. 2, when the cam has four noses, each of the four noses is on its upper side when the cam rotates once. Since it is possible to perform excitation on the arranged sieve plate 21 or perforated plate 3, vibrations caused by four hits per rotation of the cam may be applied to the sieve plate 21 or the perforated plate 3. However, the excitation unit 22 is not limited to the cam type. As another example, the excitation unit 22 may be a vibration motor.

2 to 4, the sieve plate portion 2 may include a storage portion 23 disposed to receive particles that pass through the front ends of the plurality of sieve plates 21 and depart.

Specifically, referring to FIGS. 1B and 2 to 5, the storage unit 23 contains particles larger than the size of each of the sieve plates 21 among particles mined and transported by the mining unit 1 and dropped downward. It may be provided on the front side of the plurality of sieve plates 21 so as to accommodate particles that do not pass through the sieve and pass through the front ends of each of the sieve plates 21. Such a storage unit 23 is disposed on the front side of the plurality of sieve plates 21, so that the particles filtered from each of the plurality of sieve plates 21 are not separated between the plurality of sieve plates 21 and the storage unit 23, a plurality of It may be formed in contact with the front end of the sieve plate 21 (to be connected continuously).

In addition, the storage unit 23 may be provided with a storage space partitioned in the vertical direction so that particles separated from the plurality of sieve plates 21 are classified and stored by the plurality of sieve plates 21.

For example, referring to the drawings, the storage space of the storage unit 23 may be formed in a number corresponding to the number of a plurality of sieve plates 21. As described above, the plurality of sieve plates 21 may be provided so that the sieve size decreases as it goes downward, and in conjunction with the gradually decreasing sieve size as it goes downward, the storage unit ( The storage space of 23) is also divided and thus filtered particles (plastic particles) can be classified by particle size. Exemplarily, referring to FIG. 3, a first storage unit 23a may be formed corresponding to a first sieve plate 21a having a body size a among the plurality of sieve plates 21, and b In response to the phosphorus second sieve plate 21b, the second storage unit 23b may be formed by being divided (divided) separately from the first storage unit 23a.

2 to 5, the storage unit 23 is moved along the forward downward slope of the plurality of sieve plates 21 to receive and receive (storage) particles that deviate from the front end portions ( A portion connected to (abutting) the front end portion of 21) may be provided in an open (open) shape. However, the storage space of the storage unit 23 is a closed shape so that the accommodated particles can be stored in the storage unit 23 without escaping to the outside, except for an opening part of the storage space that contacts the front ends of the plurality of sieve plates 21 It can be provided as.

On the other hand, the device 100 prevents the filtered particles from passing through the sieve from the sieve plate 2 and from being separated to the outside other than the storage 23, the sieve plate 2 excluding the upper and lower areas. It may include a closed frame 25 surrounding the circumferential region. Although the reference numerals are not clearly indicated in FIGS. 1A and 1B, the closed frame 25 refers to a frame corresponding to the main body surrounding the circumference of the sieve portion 21 as viewed in FIGS. 1A and 1B. It can be understood as.

Here, the particles that are filtered without passing through the sieve in the sieve portion 2 may be understood as referring to all particles that have not passed through to the lowermost sieve plate, which can be referred to as the lowest maginot line among the plurality of sieve plates 21. .

However, referring to FIGS. 2 to 5, the closed frame 25 has a closed structure except for the upper and lower regions, but a portion connected to the storage unit 23, that is, a plurality of sieve plates 21, respectively A portion in contact with the front end portion of each of the plurality of sieve plates 21 through which the filters filtered by the filter are moved to the storage unit 23 may be provided in a shape that is open toward the storage unit 23 without being closed. In addition, the closing frame 25 may be run (installed) a hinged door for the purpose of manufacturing, maintenance, inspection, and the like.

2 to 4, in the sieve plate part 2, some of the particles discharged to the bottom of any one of the remaining sieve plates except for the lowest sieve plate located at the lowermost side are moved to the rear opposite to the storage unit 23. Then, it may include a sieve plate lower guide 24 that guides (guides) to be dropped downward to a lower sieve plate located below any one of the remaining sieve plates. In this case, the front end of the sieve plate lower guide 24 may be located below the front end of any one of the remaining sieve plates.

The sieve plate lower guide 24 may be provided for at least one of the remaining sieve plates except for the lowermost sieve plate. Illustratively, referring to the drawings, the sieve plate lower guide 24 may be provided on all of the sieve plates except for the lowermost sieve plate, but is not limited thereto.

In this case, the sieve plate lower guide 24 may be formed in a closed structure in the form of a wide plate so that particles can be moved to the rear region of the lower sieve plate and then dropped downward, as described later. In other words, the sieve plate lower guide 24 may be provided in the form of a solid plate in which no sieve is formed unlike the sieve plate, and as it is provided in a solid plate shape, it passes through the upper sieve plate instead of performing a filtering function. In contrast to the fact that one particle moves directly to the sieve plate on the lower side, it can perform the function of moving the particles relatively backward and then dropping them onto the sieve plate on the lower side. Exemplarily, the length of the transverse direction (direction orthogonal to the normal direction in the drawing with respect to the front and rear directions) of the lower guide 24 of the sieve plate is plural to cover most of the particles passing through each of the sieve plates 21. The sieve plate 21 may be formed to be substantially the same as the length in the transverse direction of each, but is not limited thereto.

In addition, the sieve plate lower guide 24 may be inclined to be inclined downwardly to the rear opposite to the plurality of sieve plates 21. In other words, the sieve plate lower guide 24 may be tilted downwardly inclined forward, while the sieve plate lower guide 24 may be tilted downwardly inclined backward. Here, the downward slope to the rear may mean that a downward slope is formed toward the rear.

In addition, the sieve plate lower guide 24 may be provided to receive vibration applied by the excitation unit 22. The above-described excitation unit 22 vibrates not only the sieve plate 2 but also the sieve plate lower guide 24 to move the particles present on the sieve plate lower guide 24 backward along the rear downhill slope. It can be provided to let. Exemplarily, the vibrating unit 22 may be separately provided for each of the sieve plate 21 and the sieve plate lower guide 24, and simultaneously hold the sieve plate 21 and the sieve plate lower guide 24 corresponding thereto. It may be provided in a form in which this can be achieved. As an example, referring to FIG. 3, the excitation unit 22 may be provided so that excitation can be simultaneously formed at the front lower end of the sieve plate 21 and the front upper end of the sieve plate lower guide 24 corresponding thereto. . As another example, one vibrating unit 22 is provided at the rear upper end of the sieve plate 21 to perform excitation of the sieve plate 21, and the other vibrating unit 22 is the front top of the sieve plate lower guide 24 It is provided in the sieve plate to perform excitation of the lower guide 24, in which case the excitation unit 22 provided at the front upper end of the sieve plate lower guide 24 is not only the excitation of the sieve plate lower guide 24, but also the sieve plate 21 It can also be practiced.

When using the sieve plate lower guide 24, if there is no sieve plate lower guide 24, some of the particles to be dropped on the front area of the lower sieve plate are moved to the rear by the sieve plate lower guide 24, so that the front side of the lower sieve plate It can be dropped in the rear area which is relatively rear than the area.

The anterior region of the lower sieve plate refers to an area that generally corresponds to the front side of the lower sieve plate, and may generally refer to the front portion corresponding to half when the sieve plate is divided in half, but is limited thereto. No, as another example, the front region of the lower sieve plate may be referred to as a front portion approximately 1/3 to 2/3 of the lower sieve plate.

The sieve plate lower guide 24 is, in the case of the particles 400 dropped on the front area of the lower sieve plate (see FIG. 4A(b)), the particles 400 dropped on the rear area relatively rear (FIG. 4A(a) )), the filtering time in the sieve plate may be less than that of the sieve plate, so it may play a role of moving some of the particles 400 dropped on the front region of the lower sieve plate to the rear.

More specifically, referring to FIGS. 4A(b) and 4B, the sieve plate lower guide 24 is lower than when the sieve plate lower guide 24 does not have some of the particles 400 dropped on the front area of the lower sieve plate. By allowing them to stay in the sieve plate for a long time, it is possible to assist so that the filtration process can be carried out to a similar degree to the particles 400 dropped on the rear area, which is relatively behind the lower sieve plate, as illustrated by way of example in Fig. 4A(a). And, accordingly, it is possible to further increase the filtration efficiency.

5 is a cross-sectional view for explaining a perforated plate configuration and a cover configuration of the plastic particle filtration separation device according to an embodiment of the present application, and FIG. 6 is formed on the perforated plate of the plastic particle filtration separation device according to an embodiment of the present application. In order to illustrate the perforated configuration as an example, it is a view showing a state of a partial area of the perforated plate as viewed from the upper side of the perforated plate, and FIG. 7 is an exemplary configuration of a perforated plate and a cover configuration of the plastic particle filtration separation apparatus according to an embodiment of the present application. It is a conceptual diagram for explanation.

The device 100 may include a perforated plate 3.

Referring to FIGS. 5 and 7, the perforated plate 3 may be disposed at an upwardly spaced distance from the uppermost sieve plate among the plurality of sieve plates 21. In addition, the perforated plate 3 may be disposed inclined downwardly inclined forward.

Here, the downward slope toward the front may mean that a downward slope toward the front is formed as described above. For example, the inclination angle of the perforated plate may be set to be substantially the same as the inclination angle of the plurality of sieve plates 21 described above (an inclination angle disposed parallel to the uppermost sieve plate among the plurality of sieve plates 21), It is not limited to this.

In addition, a plurality of perforations (holes) may be formed in the perforated plate 3. Referring to FIG. 6, a plurality of perforations may be formed in a pattern shape that is repetitive in the front-rear direction and the transverse direction. Exemplarily, referring to FIG. 5, a plurality of perforations formed in the perforated plate 3 is an inlet formed in the cover 4 to be described later (a partial area of the cover so that particles dropped downward from the mining can reach onto the perforated plate. It may not be formed under this open part) 4a. If a plurality of perforations is also formed on the lower side of the inlet (4a), since the elongated impurities that are dropped downward along with the particles cannot be filtered and may pass through the plurality of perforations and reach the uppermost sieve plate, the plurality of perforations is It is preferable that it is not formed on the lower side of.

3 and 5 together, the size of the perforation (d) is set to be larger than the size (a) of the uppermost sieve plate located at the top of the plurality of sieve plates 21, but larger than the sand particles and the plastic particles It may be set to a size limiting the passage of at least some of the impurities of.

In the case of coastal/river banks, there is a high possibility that the sand contains impurities (non-particles such as sand or microplastic) other than fine plastics with a small radius such as tree branches. Accordingly, in the present apparatus 100, the sieve plate 21 is configured to pre-filter impurities other than particles so that the sieve plate 21 can perform a more effective (intensively) filtering function for particles such as sand or microplastic. The perforated plate 3 may be disposed on the upper side of the sieve plate 21. In the present application, the purpose of the perforated plate 3 is primarily to separate particles of a predetermined size or more determined by the hole size of the perforated plate 3 without passing through. Since large-sized impurities are highly likely to be various garbage, they are intended to be filtered out in advance using the perforated plate (3). For example, among the large-sized impurities, an elongated impurity may also be included. As will be described later, in the case of an elongated object, by placing the cover 4 on the perforated plate 3 in order to prevent entry into the hole of the perforated plate 3 in an upright state, the elongated impurities can be induced to move in a lying state rather than an elongated state. I can.

In addition, as an example, when the sieve size (a) of the uppermost sieve plate is 5 mm, the size (d) of the perforation may be set to exceed 5 mm. In other words, the size d of the perforation may be set to a size such that at least some of impurities having a size larger than that of sand particles and plastic particles are not dropped downward onto the plurality of sieve plates 21. However, in the case where the perforated plate 3 filters impurities that are elongated in one direction (anisotropic or anisotropic on the side of the length) among various impurities in connection with the cover 4, the perforation size (d) of the perforated plate 3 ) Prevents such elongated impurities from passing through in a state in which the impurities are laid down without being erected by the cover 4 (the state that the impurity is placed on the perforated plate 3 so that the length direction of the impurity is parallel to the surface direction of the perforated plate 3) Can be set to size. In this case, the perforation size d of the perforated plate 3 may be set sufficiently larger than 5 mm, for example, 10 mm or more, but is not limited thereto.

In addition, referring to FIGS. 6 and 7, the plurality of perforations may be formed such that an interval s between adjacent perforations in the front-rear direction is set to be wider than the front-rear width d of the perforations.

Here, the front-rear direction may be a direction in which an inclination is formed in the sieve plate 21 or the perforated plate 3. Referring to FIG. 5, the sieve plate 21 or the perforated plate 3 may be provided to have a slope that is downhill from the rear toward the front. Based on the front-rear direction in which the inclination is formed as described above, the plurality of perforations reach on the perforated plate 3 by being formed such that the distance (s) with neighboring perforations in the front-rear direction is set wider than the front-rear width (d) of the perforations. The number of times the impurity meets the perforation on the forward impurity movement path when the elongated impurity in a lying state moves forward gradually along the ramp of the perforated plate 3 according to the excitation of the excitation unit 22 (the number of passing over the perforation ) Can be further reduced, thereby lowering the likelihood (probability) that impurities will enter the perforation. However, it is desirable that particles such as sand or fine plastic other than impurities pass through the perforation as quickly as possible, so it is recommended that the spacing (s) of the other spaces in the front-rear direction is set wider than the width (d) in the front-rear direction of the perforation. May not be. Referring to the examples of the perforated plate shown in Figs. 6 and 7, the spacing (s) of the other space in the front-rear direction is within 2 times of the width (d) in the front-rear direction of the perforation (e.g., more than 1, within 1.5 times ) Is preferably set.

In addition, referring to FIGS. 6 and 7, each of the plurality of perforations may be formed so as to be displaced from neighboring perforations in the transverse direction. For reference, referring to FIG. 6, the transverse direction may mean a horizontal direction orthogonal to the front-rear direction. In addition, referring to the partially enlarged view of FIG. 6, it means that each of the plurality of perforations is arranged to be offset from each other in the transverse direction, and that the perforations adjacent in the transverse direction with respect to any one perforation are referenced to any one of the above. As a result, the neighbors are not exactly spaced in the lateral direction, but in an oblique direction (for example, approximately 30 degrees to 60 degrees) with a predetermined acute angle (an angle less than 90 degrees) with respect to the correct transverse direction. It can mean being placed. In other words, the fact that each of the plurality of perforations is arranged to deviate from each other in the transverse direction means that a perforation adjacent in the transverse direction is located between any one perforation and the other perforations adjacent in the front and rear direction. It can mean doing. Further, from the other side, the fact that each of the plurality of perforations is arranged to be offset from each other in the transverse direction is that any one perforation and the perforations adjacent in the transverse direction are exactly the same in the transverse direction. It may mean that it is not formed at a position, but is formed at a position that deviates from the transverse direction and shifts in the front-rear direction. In addition, referring to the dotted line marks in the partially enlarged view of FIG. 6, the arrangement shape of the perforations arranged to deviate from each other in the lateral direction may also be expressed as a zigzag arrangement shape.

Meanwhile, the device 100 may include a lower guide 3a of the perforated plate. The perforated plate lower guide 3a may be understood as a configuration that performs the same or similar function as the sieve plate lower guide 24 described above. That is, the perforated plate lower guide 3a is the uppermost side of the plurality of sieve plates 21 after some of the particles discharged downward through the perforated plate 3 are moved to the rear opposite to the outlet of the cover 4 to be described later. It may be a configuration that guides (guides) to be dropped downward to the uppermost sieve plate located at. For example, the excitation unit 22 may be provided so that the excitation unit 22 having the perforated plate 3 also has the lower guide 3a of the perforated plate, or the excitation unit 22 having the perforated plate 3 and Each of the excitation units 22 having the perforated plate lower guide 3a may be separately provided. This perforated plate lower guide 3a can be understood in the same or similar to the configuration of the sieve plate lower guide 24 except for the difference that it is not installed with respect to the sieve plate 21 but is installed with respect to the perforated plate 3, so a more detailed description Is omitted.

The device 100 may include a cover 4. The cover 4 may be inclined downwardly inclined forward (aligned to form a downward slope forward). Illustratively, referring to FIGS. 5 and 7, the cover 4 may be provided to have an inclination parallel to the perforated plate 3 so that a certain gap can be formed between the perforated plates 3, but is limited thereto. It does not become. As another example, the cover 4 may be provided to have a gentle slope than the perforated plate 3. In addition, the cover 4 may have a flat plate shape, that is, a cover plate shape, but is not limited thereto.

2, 5, and 7, the cover 4 has a shape in which a partial area is opened so that the particles mined and transported by the mining unit 1 and then dropped downward can reach onto the perforated plate 3 The furnace inlet 4a may be formed. Referring to Figure 2, the inlet (4a) is the most of the particles dropped downward from the bucket (11) reaching the upper side along the chain belt (12) can be dropped into the inlet (4a) without leaving the inlet (4a). It is desirable to be formed in a sufficient size to the extent that there is.

Referring to FIGS. 2, 5 and 7, the inlet 4a of the cover 4 may be formed on the rear side corresponding to the upper area of the ramp formed by the perforated plate 3.

Here, the upper region refers to an upper portion (upper part) of the slope where the slope starts based on the slope that is inclined downward. The upper region is a term set based on the vertical direction, and can be regarded as a rear region when the front and rear directions are referenced.

Referring to FIG. 2, since the mining unit 1 has a structure in which particles such as sand are mined from the rear of the sieve unit 2 and then transferred to the upper side of the sieve unit 2, a plurality of the mining units 1 A position at which the bucket 11 reaching the upper side of the bucket 11 drops the mined particles downward may be an upper side of the rear area of the sieve plate portion 2. Accordingly, the inlet 4a of the cover 4 may be formed above the rear area of the sieve plate 2. That is, the inlet 4a of the cover 4 may be formed to have a size of a region including a point at which the particles mined and transported by the mining unit 1 are dropped downward.

Referring to FIGS. 5 (especially, an enlarged view of the couple of FIG. 5) and 7, the cover 4 may be disposed at a distance h upward from the perforated plate 4 to cover the perforated plate 3. However, as described above, since the cover 4 is provided with the inlet 4a, the inlet 4a region may be opened without covering the perforated plate 3.

Referring to FIG. 5, in the space formed by the gap (h) between the perforated plate 3 and the cover 4, the residue (bulsulmun) that did not pass through the perforation interlocks with the excitation of the excitation unit 22. It can be gradually moved forward along the ramp.

In addition, referring to Figure 5, in the front (front end) between the perforated plate 3 and the cover 4, impurities that have not passed through the perforations on the perforated plate 3 and have moved forward along a downwardly inclined slope are discharged to the outside. An impurity discharge port 4b opened to be opened may be formed.

In addition, the distance (h) between the perforated plate 3 and the cover 4 is perforated with an elongated impurity 500 having a length greater than n times (here, n is a number greater than 1) larger than the width of the short side among impurities. In order to prevent passing through, it may be set to less than n times the size of the perforation (d). For example, n times may be set to 2 times or more.

Specifically, when the direction in which the elongated impurity 500 is elongated is the length direction of the impurity 500, the shortest width is the shortest side width, and the shortest width on the cross section of the impurity 500 cut to be orthogonal to the length direction. Long width can be defined as long side width. Meanwhile, among the objects mined by the bucket 11, impurities may be included in addition to particles such as sand or microplastic. As described above, in the case of an elongated impurity (for example, a tree branch, etc.) having a length n times or more than the width of the short side among the impurities included in the bucket 11, the gap between the perforated plate 3 and the cover 4 ( By setting h) to less than n times the size of the perforation (d), it is physically possible to erect an elongated impurity 500 whose length is n times or more than the width of the short side in the space between the perforated plate 3 and the cover 4 Since the source may be blocked, the probability of passing through the holes of the elongated impurities 500 may be lowered. In other words, the elongated impurity 500 cannot be erected in the space (h) between the perforated plate 3 and the cover 4, and the lengthwise direction is on the perforated plate 3 only in a lying state toward the surface direction of the perforated plate 3. Can be restricted to move.

In addition, the distance h between the perforated plate 3 and the cover 4 is the elongated impurity 500 so that it is allowed to move between the perforated plate 3 and the cover 4 while the elongated impurity 500 is lying down. It can be set at an interval greater than the width of the short side of. 5 and 7, the elongated impurity 500 must be able to enter the space formed by the gap h between the perforated plate 3 and the cover 4, through the space, along a downward slope. Since it is gradually moved forward and can be discharged through the impurity discharge port 4b in front, the distance h between the perforated plate 3 and the cover 4 is the thickness (height) in the state where the elongated impurity 500 is lying down. It is preferable in terms of allowing entry and allowing movement to be set larger. However, in general, since the long side of the elongated impurity 500 is in contact with the upper surface of the perforated plate 3 and the relatively narrow side of the short side corresponds to the thickness (height), between the perforated plate 3 and the cover 4 It is preferable that the interval h of the elongated impurity 500 is set to be larger than the width of the short side corresponding to the thickness of the elongated impurity 500 in the lying state.

On the other hand, although not clearly shown in the drawings, in the device 100, particles containing moisture among the particles mined and transported by the mining unit 1 are adhered to the inside of the device 100 to interfere with filtration or In the case of lowering the, it may include a plurality of injection ports for spraying at least one of air and water to particles containing moisture on the sieve plate 2 or the perforated plate 3. In addition, by way of example, the sprayed air may be hot air to dry the particles.

In addition, the device 100 may include a vehicle unit 5. 1A, 1B, and 2, the vehicle unit 5 is configured to move the mining unit 1 and the sieve unit 2. For example, the vehicle unit 5 may be used when the device 100 wants to move to the next filtering target location after performing a series of steps (operations) such as mining, transporting, and filtering. For example, the vehicle unit 5 may include a wheel and a driving force providing unit that provides driving force to the wheel. In addition, the vehicle unit 5 may include a control unit that controls a wheel, a driving force providing unit, and the like. In addition, the vehicle unit 5 may include a sensor unit including at least one sensor that collects (detects) information such as the position and speed of the vehicle by time during the operation of the device 100. In addition, the vehicle unit 5 includes a movement direction switching structure provided to perform a function of changing the rolling direction of the wheel while moving at a low speed on the sand, considering that the device 100 can be moved on the sand. can do. However, the configuration of the vehicle unit 5 is not limited to a combination of one or more of the above-described configurations, and various known configurations or various configurations to be developed in the future may be applied to the vehicle unit 5 of the device 100. have.

Hereinafter, the overall contents of the device 100 will be exemplarily summarized and described.

The plastic particle filtration separating apparatus according to an embodiment of the present application operates on a sandbar using a wheel, and uses a bucket-chain that can adjust the angle to extract sand at a desired point and transfer it to the top of the device. The transferred sand is dropped on the multi-layer inclined sieve plates 21 installed in the body closed in all directions except for the top and bottom. In the multi-layered sieve plates 21, the eyes of the sieve are smaller as they go from top to bottom, and the eyes of the last sieve are larger than the size of sand particles. By vibrating the sieve plate, particles larger than the eyes of each sieve are separated/stored in a bucket installed at the end of the slope, and the sand falls back under the open device.

More specifically, referring to FIGS. 1A and 1B, the apparatus 100 for filtering and separating plastic particles according to an embodiment of the present disclosure extracts sand while maneuvering on a sandbar through a wheel and separates and filters the plastic particles through a sieve. The remaining sand is thrown under the device. The mining of sand is carried out using a bucket-chain, and the angle can be adjusted around one side of this bucket-chain, so mining can be carried out and stopped from the desired location. The bucket-chain comprises a number of buckets 11 connected to a rotating chain belt 12 between two chain gears, where sand is mined and then transported upwards of the device and dropped onto the body of the device. The main body is closed in all directions except for the top and bottom, and has a multi-layered sieve plate 21 installed at an angle. As the sieve plate 21 goes from top to bottom, the eyes of the sieve become smaller, and the eyes of the bottom sieve plate are slightly larger than the sand particles in the place where the device is used. The sand dropped by the bucket-chain on the body is dropped on the first sieve plate, and particles larger than the sieve's snow are moved along the slope and stored in a bucket installed at the end of the slope by vibrating the sieve plate. Particles smaller than the sieve's eyes are placed underneath and then dropped onto the sieve plate and behave in the same way. The sand particles that have passed through the bottom sieve plate fall under the open device and are returned to the original mined environment.

In this way, the plastic particle filtration separation apparatus 100 according to an embodiment of the present application continuously extracts sand and transfers it to the apparatus, and drops it into a closed space so that the particles do not escape during filtration, and a multi-layer vibrating sieve plate ( 21) is used to separate general garbage, fine plastic particles, and sand particles.

Meanwhile, referring to FIGS. 2 to 4, the sieve plate unit 2 may include a sieve plate lower guide 24 that guides (guides) at least one lower portion of the plurality of sieve plates 21. In the filtration by the sieve plate that the sieve plate lower guide 24 is obliquely disposed (inclined arrangement), particles that are later filtered in the lower portion of the ramp may not have time to be filtered in the next sieve plate lower than the sieve plate. The inventor of the present application recognized this difficulty and provided a configuration of the sieve plate lower guide 24 that guides (guides) the particles filtered from the lower part of the slope to move to the upper part relative to the lower part of the next sieve plate. . 2 to 4, the sieve plate lower guide 24 may be provided to have a reverse slope in a direction opposite to the inclination direction of the sieve plate. In addition, the sieve plate lower guide 24 is disposed below the sieve plate, and may be disposed corresponding to the lower portion of the inclined slope.

Further, referring to FIGS. 5 and 7, the plastic particle filtration separation apparatus 100 according to an exemplary embodiment of the present disclosure may include a perforated plate 3 and a cover 4. In the case of coastal/river banks, there is a high possibility that the sand contains impurities other than fine plastics with a small radius such as tree branches. However, if the uppermost sieve plate is used as it is, since there is a possibility that such thin and elongated impurities 500 may pass through the sieve plate 21, it is necessary to filter them out in step 1. The condition in which the thin and elongated impurities 500 pass through the sieve plate is that the thin and elongated impurities 500 must be erected, so the cover 4 is disposed on the perforated plate 3 to form a space that cannot be erected. That is, the cover 4 may be disposed on the perforated plate 3 to form a height space as large as a size in which the thin and elongated impurities 500 cannot be erected. According to this, the thin and elongated impurities 500 are bound to be laid. For example, the distance between the perforated plate 3 and the cover 4 may be set to correspond to the hole diameter of the perforated plate or set to a slightly larger degree than this.

On the other hand, with respect to the configuration of the perforated plate 3, the sieve plate 21 has a square eye so that the thin and long impurities 500 can be easily passed away, whereas the perforated plate 3 with holes in the opposite beats is blocked in several places. Because of this, the thin and long impurities 500 do not pass easily. As the distance between the perforated plate 3 and the cover 4 is larger than the perforated plate hole diameter, the thin and elongated impurities 500 may pass at an angle, so it is preferable that the distance is not too large.

As described above, the plastic particle filtration separation apparatus 100 according to an embodiment of the present disclosure may have a multilayer sieve plate 21 structure. In addition, the device may have a sieve structure that is closed in all directions except for the top and bottom. In addition, the device may have a guide configuration 24 under the sieve plate. In addition, the device may have a configuration of a perforated plate 3 and a configuration of a cover 4.

Hereinafter, a plastic particle filtration separation method (hereinafter referred to as'this method') using the plastic particle filtration separation device according to an embodiment of the present application will be described. This method is performed by using the plastic particle filtration separation apparatus according to an embodiment of the present application, and it will be said to have the same technical characteristics as or corresponding to the plastic particle filtration separation apparatus according to an embodiment of the present application. In the description of, the same reference numerals are used for configurations that are the same or similar to those of the salpin configuration while describing the present device above, and overlapping descriptions will be simplified or omitted.

8 is a flow chart illustrating a plastic particle filtration separation method using the plastic particle filtration separation device according to an embodiment of the present application.

Referring to FIG. 8, the method includes a step S110 of mining particles including at least one of sand particles and plastic particles using the mining unit 1 and transferring them upward (S110). In step S110, the process of mining the particles including at least one of sand particles and plastic particles by the mining unit 1 and transferring them upward has been described above, and thus a more detailed description thereof will be omitted.

Referring to FIG. 8, the method includes the step of sequentially filtering particles that are mined and transported by the mining unit 1 and then dropped downward using the sieve unit 2 (S130). As described above, the apparatus 100 may be provided with a perforated plate 3 and a cover 4, and in step S130, particles that are dropped downward may include particles that come out through the perforated plate as described above. In step S130, since the process of sequentially filtering the particles that are mined and transported by the sieve unit 2 and then dropped downward by the mining unit 1 has been described above, a more detailed description will be omitted.

Referring to Figure 8, the method includes the step of filtering and limiting the impurities of a size larger than the sand particles and the plastic particles reaching on the sieve plate 21 by the perforated plate 3 and the cover 4 in advance. I can. This impurity pre-filtration step may be performed between steps S110 and S130. As described above, the process of pre-filtering impurities having a size larger than that of sand particles and plastic particles using the perforated plate 3 and the cover 4 has been described above, and thus a more detailed description thereof will be omitted.

In addition, the method may include moving the apparatus 100 to another filtering work area after a series of steps such as mining, transfer, filtration, etc. including steps S110 and S130 are performed. In this moving step, the operation of moving to another filtering work area may be performed by the vehicle unit 5, and since this has been described above, a more detailed description will be omitted.

In addition, in the present method, after the moving step is completed, a series of steps such as mining, transport, filtration, etc. including steps S110 and S130 may be performed again. In other words, steps S110 and S130 may be repeatedly performed. In addition, the impurity pre-filtration steps performed in steps S110 and S130 may also be repeatedly performed together with steps S110 and S130.

Referring to FIG. 9 together with FIG. 3, a plastic particle filtration separation method using a plastic particle filtration separation apparatus according to an embodiment of the present application will be exemplarily described as follows.

First, particles having a particle size larger than d, which is the hole size of the perforated plate 3, do not pass through the perforated plate 3 and are discharged to the outside as impurities.

Next, particles having a cross-sectional width smaller than d but longer than d are not erected by the cover 4 and are moved in a lying state, so they cannot pass through the perforated plate 3 and are discharged to the outside as impurities.

Next, particles having a width smaller than d but larger than a pass through the perforated plate 3, but are moved forward without passing through the first sieve plate 21a having a sieve size a and are contained in the first storage unit 23a. At this time, some of the particles whose width is smaller than d but larger than a are transferred to the middle point of the first sieve plate 21a through the perforated plate lower guide 3a, and then move forward again to be stored in the first storage unit 23a. I can.

Next, particles having a width smaller than a but larger than b pass through the perforated plate 3 and the first sieve plate 21a, but do not pass through the second sieve plate 21b having a sieve size b, but are moved forward to the second storage unit. It is contained in (23b). At this time, some of the particles whose width is smaller than a but larger than b are transferred to the middle point of the second sieve plate 21b through the sieve plate lower guide 24 and then move forward again to be stored in the second storage unit 23b. I can.

Next, particles having a width smaller than b pass through the first sieve plate (21a) through the perforated plate (3), the first sieve plate (21a), and the second sieve plate (21b) to the lower side (the ground) of the second sieve plate (21b). Can be discharged. At this time, some of the particles having a width smaller than b that have passed through the perforated plate 3 are transferred to the middle point of the first sieve plate 21a through the lower guide 3a of the perforated plate and then move forward again or immediately It can pass through the body of (21a). In addition, some of the particles having a width smaller than b that have passed through the first sieve plate 21a in this way are transferred to the middle point of the second sieve plate 21b through the sieve plate lower guide 24 and then move forward or immediately It can pass through the eyes of the second sieve plate 21b.

The foregoing description of the present application is for illustrative purposes only, and those of ordinary skill in the art to which the present application pertains will be able to understand that other specific forms can be easily modified without changing the technical spirit or essential features of the present application. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting.
