[0002] Generally, blasting is a mechanical cleaning method performed as a pretreatment for a workpiece by spraying abrasive material onto the workpiece to remove foreign substances such as scrap, scale, rust, or coatings.

[0003] Blast methods can be classified according to the type of abrasive into sand blasting, which projects mineral particles such as silica sand or sand; shot blasting, which projects shot balls such as iron powder or cut wire; and grit blasting, which projects iron pieces with sharp angles.

[0004] Blast methods can be classified according to the projection method into air-type blast methods, which project abrasives using compressed air, and centrifugal-type blast methods, which project abrasives using centrifugal force.

[0005] Since such abrasives are mixed with foreign substances detached from the workpiece after processing, various methods are being devised to separate the abrasives from the mixture for reuse.

[0006] In addition, dust and glass granules generated during the crushing and recycling process for glass recycling fall onto the factory floor during conveyor belt transport and accumulate in large quantities; a vacuum cleaning system is used to recover these materials. At this time, the dust and solid glass granules are separated into the same type of raw material, but there were limitations in the past, such as having to re-feed large amounts into a sorter after suction and vacuum transport, or having to ship them at a low price.

[0065] The raw material collection unit (20) may further include at least one of a level sensor (211) provided in the raw material hopper (21) and a raw material vibration unit (29) that applies vibration to the raw material hopper (21).

[0066] When recycled raw material is received in the raw material hopper (21), the raw material hopper (21) and the raw material buffer chamber (25) are connected by the raw material transfer valve (23), and the recycled raw material moves from the raw material hopper (21) to the raw material buffer chamber (25). Then, the connection between the raw material hopper (21) and the raw material buffer chamber (25) is closed by the raw material transfer valve (23), and the lower opening of the raw material buffer chamber (25) is opened by the raw material discharge valve (27), so that the recycled raw material separated from the mixture can be stored in the raw material collection bag (BA) while maintaining the reduced pressure state of the raw material hopper (21).

[0067] The foreign matter collection unit (30) receives foreign matter transferred from the mixing and separation unit (10).

A foreign matter support part (313) for connecting a foreign matter filter part (332) (34) may be provided inside the foreign matter hopper (31). Since the foreign matter passes through the foreign matter inlet (311) so as to rotate inside the foreign matter hopper (31), the foreign matter inlet (311) can impart a cyclone effect to the foreign matter. Additionally, since the filtered air passes through the foreign matter filtration outlet (312) so as to be discharged while rotating inside the foreign matter hopper (31), the discharge of filtered air from the foreign matter filtration outlet (312) can be rapid, and the pressure reduction of the foreign matter hopper (31) can be smoothly facilitated. The foreign matter hopper (31) includes a foreign matter body (31a) representing a hollow enclosure with the upper and lower ends open, and a foreign matter lid (31b) that opens and closes the upper opening of the foreign matter body (31a), so that the foreign matter filter section (332)(34) can be replaced or maintained in the foreign matter hopper (31).

[0070] The foreign matter guide wing (32) is provided inside the foreign matter hopper (31). The foreign matter guide wing (32) has a funnel-like structure that is wider at the top and narrower at the bottom. The foreign matter guide wing (32) divides the inside of the foreign matter hopper (31) into an input space and a filter space. The input space is connected to the foreign matter input port (311), and the foreign matter filter section (332) (34) is connected to the filter space.

[0071] The foreign matter filter section (332)(34) is provided inside the foreign matter hopper (31) above the foreign matter guide wing (32). The foreign matter filter section (332)(34) filters foreign matter by the suction force of the vacuum suction unit (40). The foreign matter filter section (332)(34) divides the interior of the foreign matter hopper (31) into a filter space and a clean space. The clean space is connected to the foreign matter filtration outlet (312). The foreign matter filter section (332)(34) may include a foreign matter flange (331) that divides the interior of the foreign matter hopper (31) into a filter space and a clean space, and a foreign matter filter bag coupled to the foreign matter flange (331) that filters foreign matter by the suction force of the vacuum suction unit (40). A plurality of filtration holes are formed through the foreign matter flange (331). The foreign matter filter bag closes the filtration holes to allow filtered air to pass through, thereby filtering foreign matter by the suction force of the vacuum suction unit (40).

[0072] The foreign matter buffer chamber (35) represents a hollow housing with an open top and bottom. The foreign matter buffer chamber (35) is connected to the lower opening of the foreign matter hopper (31).

[0073] The foreign matter transfer valve (33) selects whether the foreign matter hopper (31) and the foreign matter buffer chamber (35) are connected.

Although not illustrated, the foreign matter pressure tank (361) may be connected to a vacuum compressor (45) included in the vacuum intake unit (40) to store compressed air.

[0077] As suction force is applied to the foreign matter hopper (31), foreign matter passing through the foreign matter inlet (311) rotates in the input space of the foreign matter hopper (31) and moves to the filter space. At this time, some of the foreign matter falls and accumulates at the bottom of the foreign matter hopper (31). The foreign matter moved to the filter space is filtered by the foreign matter filter section (332)(34), and filtered air passes through the foreign matter filter section (332)(34) and moves to the clean space. The filtered air contained in the clean space is discharged through the foreign matter filtration outlet (312). Here, when the foreign matter air pulse (36) sprays compressed air into the clean space, the foreign matter is separated from the foreign matter filter section (332)(34) and falls to the bottom of the foreign matter hopper (31). Additionally, depending on the operation of the foreign matter vibration unit (39), foreign matter is separated from the inner wall of the foreign matter hopper (31) in the input space and filter space and transferred to the lower part of the foreign matter hopper (31). As foreign matter is stacked and received in the input space of the foreign matter hopper (31), the foreign matter hopper (31) and the foreign matter buffer chamber (35) are connected by the foreign matter transfer valve (33), and the foreign matter moves from the foreign matter hopper (31) to the foreign matter buffer chamber (35). Then, after closing the connection between the foreign matter hopper (31) and the foreign matter buffer chamber (35) by the foreign matter transfer valve (33), the lower opening of the foreign matter buffer chamber (35) is opened by the foreign matter discharge valve (37), allowing the foreign matter to be stored in the foreign matter collection bag (BB) while maintaining the reduced pressure state of the foreign matter hopper (31).

[0078] The vacuum suction unit (40) provides suction power to the foreign matter collection unit (30). The vacuum suction unit (40) may include a vacuum chamber (41), a vacuum induction unit (42), a vacuum injection unit (43), and a vacuum silencer (44).

[0079] The vacuum chamber (41) represents a hollow housing with open top and bottom ends. A vacuum intake port (411) communicating with a foreign matter collection unit (30) is provided on the side of the vacuum chamber (41). A vacuum induction support part (412) is provided on the bottom of the vacuum chamber (41), and a vacuum pneumatic support part (414) is provided on the top of the vacuum chamber (41).

[0080] The vacuum induction section (42) is coupled to the lower part of the vacuum chamber (41). The vacuum induction section (42) is formed to protrude from the lower part of the vacuum chamber (41). Compressed air and filtered air delivered from the foreign matter collection unit (30) pass through the vacuum induction section (42). The vacuum induction section (42) may include a vacuum induction flange (422) coupled to the vacuum induction support section (412), and a vacuum induction funnel (421) coupled to the vacuum induction flange (422), which has a structure that is wider at the top and narrower at the bottom.

[0081] The vacuum injection unit (43) is coupled to the upper part of the vacuum chamber (41). The vacuum injection unit (43) is formed to protrude into the interior of the vacuum chamber (41) while being spaced apart from the vacuum induction unit (42). The vacuum injection unit (43) injects compressed air into the vacuum induction unit (42). The vacuum injection unit (43) may include a vacuum support flange (432) coupled to the vacuum pneumatic support unit (414), and a vacuum injection nozzle (431) coupled to the vacuum support flange (432) and injecting compressed air into the vacuum induction unit (42).

[0082] The vacuum silencer (44) suppresses noise generated by compressed air and filtered air passing through the vacuum induction section (42). The vacuum silencer (44) is coupled to the lower part of the vacuum chamber (41) and surrounds the protruding vacuum induction section (42). The vacuum silencer (44) may include a vacuum noise chamber (46) having a hollow housing and a vacuum exhaust port (461) through which noise-suppressed compressed air and filtered air are discharged, and a fluid dispersion body (47) embedded in the vacuum noise chamber (46) and dispersing the compressed air and filtered air passing through the vacuum induction section (42). The vacuum silencer (44) may further include at least one of a fluid guide body (48) that guides compressed air and filtered air passing through the fluid dispersion body (47) to the vacuum exhaust port (461), a vacuum chamber cover (49) that surrounds the vacuum noise chamber (46) corresponding to the vacuum exhaust port (461), and a sounding agent (SA) that is embedded in the vacuum noise chamber (46) or surrounds the vacuum noise chamber (46) corresponding to the vacuum exhaust port (461). The vacuum noise floor is detachably coupled to the vacuum noise chamber (46), and it is preferable that the fluid dispersion body (47) and the fluid guide body (48) are coupled to the vacuum noise floor. A plurality of fluid dispersion holes (471) that disperse the fluid passing through the vacuum guide part (42) are formed through the fluid dispersion body (47). A plurality of fluid induction holes (481) are formed through the fluid induction body (48) to disperse the fluid passing through the fluid dispersion body (47) and guide it to the vacuum exhaust port (461).

[0083] The vacuum intake unit (40) may further include at least one of a vacuum passage (42a) that forms a passage for compressed air and filtered air by connecting a vacuum induction unit (42) and a vacuum silencer (44), and a vacuum compressor (45) that supplies compressed air to a vacuum injection unit (43).

[0084] When compressed air is injected through the vacuum injection unit (43) according to the operation of the vacuum compressor (45), a large amount of filtered air passes through the vacuum induction unit (42) along with the compressed air due to the injection force of the compressed air, thereby providing suction force to the foreign matter collection unit (30). The compressed air and filtered air that have passed through the vacuum induction unit (42) are discharged to the outside through the vacuum passage (42a) and the vacuum silencer (44), so noise generated by the compressed air and filtered air can be suppressed.

[0085] A vacuum transfer system for automatic raw material separation and discharge according to one embodiment of the present invention may further include either a mixing supply unit or a vacuum cleaner.

[0086] The mixing supply unit supplies the mixture to be separated to the mixing separation unit (10). The mixing supply unit can supply the mixture to the mixing separation unit (10) through various known forms, such as a gravity method, a conveyor method, or a pneumatic transfer method.

[0087] The vacuum cleaner sucks up the mixture at the site and supplies it to the mixing separation unit (10).

[0089] Now, with reference to FIGS. 1 to 7 and FIGS. 8 and FIGS. 9, a vacuum transfer system for automatic discharge of raw materials according to another embodiment of the present invention will be described. The vacuum transfer system for automatic discharge of raw materials according to another embodiment of the present invention may include a mixing separation unit (10), a raw material collection unit (20), a first collection unit (30a), a first intake unit (40a), a second collection unit (30b), and a second intake unit (40b).

[0090] The mixing separation unit (10) separates the mixture into recycled raw materials, a first foreign matter, and a second foreign matter. The mixing separation unit (10) includes a mixing separation device according to one embodiment of the present invention and has a structure in which an intermediate discharge port (168) is further provided in the separation chamber (15). More specifically, the intermediate discharge port (168) is spaced apart from the other side of the separation chamber (15) and positioned below the foreign matter discharge port (167). It is preferable that the intermediate discharge port (168) be positioned below the coupling portion of the third guide separation part (13) or below the pivot center of the third guide separation part (13). In a vacuum transfer system for automatic raw material separation discharge according to another embodiment of the present invention, a mixing separation unit (10) that is pivot-type and detachable is shown as illustrated in FIG. 9.

[0091] As suction force is provided to the separation chamber (15), the mixture is sucked in through the mixing suction port (166), and the mixture is separated into recycled raw material, first foreign matter, and second foreign matter by the first guide separation unit (11), the second guide separation unit (12), and the third guide separation unit (13). The recycled raw material falls to the bottom of the opening separation chamber (15) after passing through the first area and the third area, and the first foreign matter is discharged through the foreign matter discharge port (167) after passing through the first area and the second area in sequence or through the first area, the third area, and the second area in sequence, and the second foreign matter is discharged through the intermediate discharge port (168) after passing through the first area, the second area, and the third area in sequence. The first foreign matter has a lower specific gravity or a form with smaller particles compared to the second foreign matter.

[0092] The raw material collection unit (20) receives the recycled raw material falling from the mixing and separation unit (10). The raw material collection unit (20) may have the same configuration as the raw material collection unit (20) included in the vacuum transfer system for automatic discharge of raw material separation according to one embodiment of the present invention.

[0093] More specifically, the raw material collection unit (20) includes a raw material hopper (21) that has a hollow housing with upper and lower openings and communicates with the lower opening of the separation chamber (15), a raw material buffer chamber (25) that has a hollow housing with upper and lower openings and communicates with the lower opening of the raw material hopper (21), a raw material transfer valve (23) that selects whether the raw material hopper (21) and the raw material buffer chamber (25) are in communication, and a raw material discharge valve (27) that opens and closes the lower opening of the raw material buffer chamber (25).

[0094] The raw material collection unit (20) may further include at least one of a level sensor (211) provided in the raw material hopper (21) and a raw material vibration unit (29) that applies vibration to the raw material hopper (21).

[0095] When recycled raw material is received in the raw material hopper (21), the raw material hopper (21) and the raw material buffer chamber (25) are connected by the raw material transfer valve (23), and the recycled raw material moves from the raw material hopper (21) to the raw material buffer chamber (25). Then, the connection between the raw material hopper (21) and the raw material buffer chamber (25) is closed by the raw material transfer valve (23), and the lower opening of the raw material buffer chamber (25) is opened by the raw material discharge valve (27), so that the recycled raw material separated from the mixture can be stored in the raw material collection bag (BA) while maintaining the reduced pressure state of the raw material hopper (21).

[0096] The first collection unit (30a) receives the first foreign matter transferred from the mixing and separation unit (10). The first collection unit (30a) may have the same configuration as the foreign matter collection unit (30) described above.

[0097] More specifically, the first collection unit (30a) may include a first hopper, a first guide wing, a first filter section, a first buffer chamber, a first transfer valve, and a first discharge valve.

[0098] The first hopper represents a hollow housing with an open bottom. A first inlet is provided at the lower side of the first hopper and is connected to the foreign matter discharge port (167) of the separation chamber (15), and a first filtration outlet is provided at the upper side of the first hopper for discharging filtered first filter air. A first support member for connecting a first filter unit may be provided inside the first hopper. Since the first foreign matter passes through the first inlet so as to rotate inside the first hopper, the first inlet can impart a cyclone effect to the first foreign matter. Additionally, since the first filter air passes through the first filtration outlet so as to rotate and be discharged inside the first hopper, the discharge of the first filter air from the first filtration outlet can be rapid, and the depressurization of the first hopper can be facilitated. The first hopper includes a first body having a hollow enclosure with the top and bottom open, and a first lid that opens and closes the top opening of the first body, so that the first filter section can be replaced or maintained in the first hopper.

[0099] The first guide wing is provided inside the first hopper. The first guide wing exhibits a funnel structure that is wider at the top and narrower at the bottom. The first guide wing divides the interior of the first hopper into a first input space and a first filter space. The first input space is connected to the first input port, and a first filter unit is connected to the first filter space.

[0100] The first filter unit is provided inside the first hopper on the upper side of the first guide wing. The first filter unit filters the first foreign matter by the suction force of the first intake unit (40a). The first filter unit divides the interior of the first hopper into a first filter space and a first clean space. The first clean space is connected to the first filtration outlet. The first filter unit may include a first flange that divides the interior of the first hopper into a first filter space and a first clean space, and a first filter bag coupled to the first flange that filters the first foreign matter by the suction force of the first intake unit (40a). A plurality of first filtration holes are formed through the first flange. The first filter bag closes the first filtration holes to allow the first filter air to pass through, thereby filtering the first foreign matter by the suction force of the first intake unit (40a).

[0101] The first buffer chamber represents a hollow enclosure with openings at the top and bottom. The first buffer chamber is connected to the bottom opening of the first hopper.

[0102] The first transfer valve selects whether the first hopper and the first buffer chamber are connected.

[0104] The first collection unit (30a) may further include at least one of a first air pulse that separates the first foreign matter from the first filter unit by pneumatic pressure and a first vibration unit that imparts vibration to the first hopper.

[0105] The first air pulse may include a first pressure tank in which the first compressed air is stored, a first filtration path that connects the first pressure tank and the first clean space to form a path for the first compressed air, and a first filtration valve that opens and closes the first filtration path. Although not illustrated, the first pressure tank may be connected to a first compressor included in the first intake unit (40a) to store the first compressed air.

[0106] As suction force acts on the first hopper, the first foreign matter passing through the first inlet rotates in the first input space of the first hopper and moves to the first filter space. At this time, a portion of the first foreign matter falls and accumulates at the bottom of the first hopper. The first foreign matter moved to the first filter space is filtered by the first filter unit, and the first filtered air passes through the first filter unit and moves to the first clean space. The first filtered air contained in the first clean space is discharged through the first filter outlet. Here, when the first air pulse sprays the first compressed air into the first clean space, the first foreign matter is separated from the first filter unit and falls to the bottom of the first hopper. Additionally, depending on the operation of the first vibration unit, the first foreign matter is separated from the inner wall of the first hopper in the first input space and the first filter space and is delivered to the bottom of the first hopper. As the first foreign material is stacked and received in the first input space of the first hopper, the first hopper and the first buffer chamber are connected by the first transfer valve, causing the first foreign material to move from the first hopper to the first buffer chamber. Then, by closing the space between the first hopper and the first buffer chamber with the first transfer valve and opening the lower opening of the first buffer chamber with the first discharge valve, the first foreign material can be stored in the first collection bag (B1) while maintaining the reduced pressure state of the first hopper.

[0107] The first intake unit (40a) provides suction power to the first collection unit (30a). The first intake unit (40a) may have the same configuration as the vacuum intake unit (40) described above.

The first injection unit is formed to protrude into the interior of the first chamber, spaced apart from the first guide unit. The first injection unit injects first compressed air into the first guide unit. The first injection unit may include a first support flange coupled to the first pneumatic support unit, and a first injection nozzle coupled to the first support flange and injecting first compressed air into the first guide unit.

[0112] The first silencer suppresses noise generated by the first compressed air and the first filtered air passing through the first guide section. The first silencer is coupled to the lower part of the first chamber and surrounds the protruding first guide section. The first silencer may include a first noise chamber having a hollow housing and a first exhaust port through which the noise-suppressed first compressed air and the first filtered air are discharged, and a first dispersion body embedded in the first noise chamber and dispersing the first compressed air and the first filtered air passing through the first guide section. The first silencer may further include at least one of a first guide body that guides the first compressed air and the first filtered air passing through the first dispersion body to the first exhaust port, a first chamber cover that surrounds the first noise chamber corresponding to the first exhaust port, and a noise agent (SA) that is embedded in the first noise chamber or surrounds the first noise chamber corresponding to the first exhaust port. The first noise bottom is preferably detachably coupled to the first noise chamber, and the first dispersion body and the first guide body are preferably coupled to the first noise bottom. A plurality of first dispersion holes are formed through the first dispersion body to disperse the fluid passing through the first guide section. A plurality of first guide holes are formed through the first guide body to disperse the fluid passing through the first dispersion body and guide it to the first exhaust port.

[0113] The first intake unit (40a) may further include at least one of a first flow path that connects a first guide unit and a first silencer to form a flow path for the first compressed air and the first filtered air, and a first compressor that supplies the first compressed air to the first injection unit.

[0114] When the first compressed air is injected through the first injection section according to the operation of the first compressor, a large amount of the first filtered air passes through the first induction section together with the first compressed air due to the injection force of the first compressed air, thereby providing suction force to the first collection unit (30a). The first compressed air and the first filtered air that have passed through the first induction section are discharged to the outside through the first flow path and the first silencer, so noise generated by the first compressed air and the first filtered air can be suppressed.

[0115] The second collection unit (30b) receives the second foreign matter delivered from the mixing and separation unit (10). The second collection unit (30b) may have the same configuration as the foreign matter collection unit (30) described above.

[0116] More specifically, the second collection unit (30b) may include a second hopper, a second guide wing, a second filter section, a second buffer chamber, a second transfer valve, and a second discharge valve.

[0117] The second hopper represents a hollow housing with an open bottom. A second inlet is provided at the lower side of the second hopper and communicates with the intermediate outlet (168) of the separation chamber (15), and a second filtration outlet is provided at the upper side of the second hopper for discharging filtered second filter air. A second support member for connecting the second filter unit may be provided inside the second hopper. Since the second foreign matter passes through the second inlet so as to rotate inside the second hopper, the second inlet can impart a cyclone effect to the second foreign matter. Additionally, since the second filter air passes through the second filtration outlet so as to rotate and be discharged inside the second hopper, the discharge of the second filter air from the second filtration outlet can be rapid, and the depressurization of the second hopper can be facilitated. The second hopper includes a second body having a hollow housing with the top and bottom open, and a second lid that opens and closes the top opening of the second body, so that the second filter section can be replaced or maintained in the second hopper.

[0118] The second guide wing is provided inside the second hopper. The second guide wing exhibits a funnel structure that is wider at the top and narrower at the bottom. The second guide wing divides the interior of the second hopper into a second input space and a second filter space. The second input space is connected to the second input port, and a second filter unit is connected to the second filter space.

[0119] The second filter unit is provided inside the second hopper on the upper side of the second guide vane. The second filter unit filters the second foreign matter by the suction force of the second intake unit (40b). The second filter unit divides the interior of the second hopper into a second filter space and a second clean space. The second clean space is connected to the second filtration outlet. The second filter unit may include a second flange that divides the interior of the second hopper into a second filter space and a second clean space, and a second filter bag coupled to the second flange that filters the second foreign matter by the suction force of the second intake unit (40b). A plurality of second filtration holes are formed through the second flange. The second filter bag closes the second filtration holes to allow the second filter air to pass through, thereby filtering the second foreign matter by the suction force of the second intake unit (40b).

[0120] The second buffer chamber represents a hollow enclosure with openings at the top and bottom. The second buffer chamber is connected to the bottom opening of the second hopper.

[0121] The second transfer valve selects whether the second hopper and the second buffer chamber are connected.

[0122] The second discharge valve opens and closes the lower opening of the second buffer chamber.

[0123] The second collection unit (30b) may further include at least one of a second air pulse that separates the second foreign matter from the second filter unit by pneumatic pressure and a second vibration unit that applies vibration to the second hopper.

[0124] The second air pulse may include a second pressure tank in which the second compressed air is stored, a second filtration path that connects the second pressure tank and the second clean space to form a path for the second compressed air, and a second filtration valve that opens and closes the second filtration path. Although not illustrated, the second pressure tank may be connected to a second compressor included in the second intake unit (40b) to store the second compressed air.

[0125] As suction force acts on the second hopper, the second foreign matter passing through the second input port rotates in the second input space of the second hopper and moves to the second filter space. At this time, a portion of the second foreign matter falls and accumulates at the bottom of the second hopper. The second foreign matter moved to the second filter space is filtered by the second filter unit, and the second filtered air passes through the second filter unit and moves to the second clean space. The second filtered air contained in the second clean space is discharged through the second filter outlet. Here, when the second air pulse sprays the second compressed air into the second clean space, the second foreign matter separates from the second filter unit and falls to the bottom of the second hopper. Additionally, depending on the operation of the second vibration unit, the second foreign matter is separated from the inner wall of the second hopper in the second input space and the second filter space and is delivered to the bottom of the second hopper. As the second foreign matter is stacked and accommodated in the second input space of the second hopper, the second hopper and the second buffer chamber are connected by the second transfer valve, causing the second foreign matter to move from the second hopper to the second buffer chamber. Then, by closing the space between the second hopper and the second buffer chamber with the second transfer valve and opening the lower opening of the second buffer chamber with the second discharge valve, the second foreign matter can be stored in the second collection bag (B2) while maintaining the reduced pressure state of the second hopper.

[0126] The second intake unit (40b) provides suction power to the second collection unit (30b). The second intake unit (40b) may have the same configuration as the vacuum intake unit (40) described above.

[0127] More specifically, the second intake unit (40b) may include a second chamber, a second guide section, a second injection section, and a second silencer.

[0128] The second chamber represents a hollow housing with the top and bottom open. A second intake port communicating with the second collection unit (30b) is provided on the side of the second chamber. A second induction support is provided on the bottom of the second chamber, and a second pneumatic support is provided on the top of the second chamber.

[0129] The second guide section is coupled to the lower part of the second chamber. The second guide section is formed to protrude from the lower part of the second chamber. The second guide section passes through the second compressed air and the second filtered air delivered from the second collection unit (30b). The second guide section may include a second guide flange coupled to the second guide support section and a second guide funnel coupled to the second guide flange, having a structure that is wider at the top and narrower at the bottom.

[0130] The second injection unit is coupled to the upper part of the second chamber. The second injection unit is formed to protrude into the interior of the second chamber, spaced apart from the second guide unit. The second injection unit injects second compressed air into the second guide unit. The second injection unit may include a second support flange coupled to the second pneumatic support unit, and a second injection nozzle coupled to the second support flange and injecting second compressed air into the second guide unit.

[0131] The second silencer suppresses noise generated by the second compressed air and second filtered air passing through the second induction section. The second silencer is coupled to the lower part of the second chamber and encloses the protruding second induction section. The second silencer may include a second noise chamber having a hollow housing and a second exhaust port through which the noise-suppressed second compressed air and second filtered air are discharged, and a second dispersion body embedded in the second noise chamber and dispersing the second compressed air and second filtered air passing through the second induction section. The second silencer may further include at least one of a second guide body that guides the second compressed air and the second filtered air passing through the second dispersion body to the second exhaust port, a second chamber cover that surrounds the second noise chamber corresponding to the second exhaust port, and a noise agent (SA) that is embedded in the second noise chamber or surrounds the second noise chamber corresponding to the second exhaust port. The second noise floor is preferably detachably coupled to the second noise chamber, and the second dispersion body and the second guide body are preferably coupled to the second noise floor. A plurality of second dispersion holes are formed through the second dispersion body to disperse the fluid passing through the second guide section. A plurality of second guide holes are formed through the second guide body to disperse the fluid passing through the second dispersion body and guide it to the second exhaust port.

[0132] The second intake unit (40b) may further include at least one of a second flow path that connects the second induction unit and the second silencer to form a flow path for the second compressed air and the second filtered air, and a second compressor that supplies the second compressed air to the second injection unit.

[0133] When the second compressed air is injected through the second injection section according to the operation of the second compressor, a large amount of the second filtered air passes through the second induction section along with the second compressed air due to the injection force of the second compressed air, thereby providing suction force to the second collection unit (30b). The second compressed air and the first filtered air that have passed through the second induction section are discharged to the outside through the first flow path and the first silencer, so noise generated by the first compressed air and the second filtered air can be suppressed.

[0134] A vacuum transfer system for automatic raw material separation and discharge according to another embodiment of the present invention may further include either a mixing supply unit or a vacuum cleaner.

[0135] The mixing supply unit supplies the mixture to be separated to the mixing separation unit (10). The mixing supply unit can supply the mixture to the mixing separation unit (10) through various known forms, such as a gravity method, a conveyor method, or a pneumatic transfer method.

[0136] The vacuum cleaner sucks up the mixture at the site and supplies it to the mixing separation unit (10).

Furthermore, it enables a continuous vacuum suction process and can achieve a recycling efficiency of over 90%. In addition, cost reduction effects can be expected by maximizing the recycling of recycled raw materials. Moreover, it features a structure that allows for customized settings at the installation site by adjusting the angle of each baffle plate in the mixing and separation unit according to the amount of dust and the density and conveying volume of the solid material, which is the recycled raw material. Furthermore, the vacuum conveying system for automatic raw material separation and discharge according to the present invention alone can drastically reduce additional processes, thereby significantly reducing costs and worker fatigue.

[0140] In addition, when the present invention is applied to a crushing and recycling process, solid glass granules, which are recycled raw materials, can be separated and discharged from the mixture in a one-stop manner, and there is an effect of reducing additional production processes required to obtain recycled raw materials.

[0141] Furthermore, clogging by the mixture can be prevented even under high vacuum through the combined relationship of the mixing and separating device. In addition, wear of the recycled material can be suppressed or prevented even under high-speed collisions through multiple guide separation sections.

[0144] In addition, through the foreign substance discharge structure of the mixing and separation device, recycled raw materials and foreign substances separated from the mixture can be automatically separated into different discharge ports. Furthermore, the foreign substances separated from the mixture can be separated by precise subdivision.

Furthermore, the raw material vibration unit (29) can facilitate the falling of recycled raw material from the raw material hopper (21) and scatter foreign substances remaining inside the raw material hopper (21), thereby improving the separation efficiency of recycled raw material.

[0154] In addition, through the detailed coupling relationship of the foreign matter collection unit (30), the filtering effect of foreign matter can be improved through the cyclone effect, the pressure state can be stably maintained inside the mixing separation unit (10) or inside the foreign matter hopper (31), and the discharge of foreign matter can be stabilized. In addition, foreign matter can be stably separated from the foreign matter filter section (332)(34) through the foreign matter air pulse (36). In addition, through the coupling relationship of the foreign matter filter section (332)(34), foreign matter in the filter space inside the foreign matter hopper (31) can be prevented from being transferred to the clean space.
