Description

Pocket-type sludge collector

[0001] The present invention relates to a pocket-type sludge collector, and more particularly, to a flight assembly that improves sludge treatment performance by increasing sludge collection capacity and mobility, and a sludge collector including the same.

[0002] Sludge is a general term for sediment generated during sewage treatment and water purification processes. If the accumulated sludge is not removed from the equipment, it can cause equipment failure. Therefore, sludge removal is necessary, both periodically and irregularly.

[0003] To remove sludge, a sludge collector is installed in sewage treatment facilities, water purification facilities, etc., and a sludge collector usually includes a plurality of flights, a plurality of sprockets, and a chain assembly. A plurality of flights are installed at a predetermined interval on a chain assembly that rotates in an endless track, and the sludge accumulated on the floor is collected and removed.

[0004] At this time, the chain assembly is supported and rotated by a plurality of sprockets, and one of the plurality of sprockets is connected to a driving unit such as a motor through a gear structure and receives driving force to rotate the chain assembly.

[0005]

[0006] Meanwhile, Fig. 1 discloses one form of a conventional flight (10) used in a sludge collector.

[0007] A conventional flight (10) may basically include a flight plate (20) and a chain connection (30). The flight plate (20) may be in the shape of a straight, long plate, and chain connection parts (30) connected to a chain assembly may be arranged on both sides of the flight plate (20).

[0008] When the chain assembly is rotated by the sprocket, the flight (10) moves along the endless track direction of the chain assembly.

[0009] During the moving process, the sludge settled on the bottom of the sludge collector is swept away and taken to the sludge collection port provided inside the sludge collector.

[0010] Referring to Figure 1, it can be seen that the flight (10) moves in the direction of the arrow and sweeps away the sludge (G).

[0011] However, since the conventional flight (10) is simply made in a straight shape, it cannot sweep away a large amount of sludge (G). While the flight (10) moves in the direction of the arrow, a significant amount of sludge (G) is lost outside the both ends of the flight plate (20) or is lost beyond the height of the flight plate (20).

[0012] This reduces the sludge collection rate and ultimately reduces the treatment performance of the sludge collector.

[0013] The present invention has been devised to solve the problems in the related technical field as described above, and the purpose of the present invention is to provide a flight assembly and a sludge collector including the same, which improve sludge treatment performance by improving sludge collection capacity and mobility.

[0014] The present invention, in order to achieve the above-described purposes, relates to a flight assembly, which may include a flight member that is bent multiple times along a longitudinal direction (Y) to form a sludge collection area; and a chain connecting member that connects the flight member and a chain assembly of a sludge collector.

[0015] Additionally, in an embodiment of the present invention, the flight member can be bent toward the direction of movement (X) from the center toward the edge.

[0016] In addition, in an embodiment of the present invention, the flight member may include a center portion arranged perpendicularly to the direction of movement (X); and bending portions connected to and bent at a predetermined bending angle (θ1) toward the direction of movement (X) on both sides of the center portion.

[0017] In addition, in an embodiment of the present invention, the flight member may further include a side portion that is bent and connected to the outer end of the bending portion at a predetermined bending angle (θ2).

[0018] Additionally, in an embodiment of the present invention, the bending angle (θ2) of the side portion can be arranged perpendicular to the moving direction (X).

[0019] Additionally, in an embodiment of the present invention, the bending angle (θ2) of the side portion may be formed to be larger than the bending angle (θ1) of the bending portion and smaller than the vertical angle (90°) with respect to the moving direction (X).

[0020] In addition, in an embodiment of the present invention, a reinforcing groove may be further included, which is formed concavely in the center portion, bending portion, or side portion in the longitudinal direction (Y) and opposite to the moving direction (X) to reinforce the rigidity of the center portion, bending portion, or side portion.

[0021] In addition, the embodiment of the present invention may further include a bending bracket, which is arranged in a plurality of pieces spaced apart from each other along the longitudinal direction (X) of the flight member and bends the flight member a plurality of times along the longitudinal direction (X).

[0022] In addition, in an embodiment of the present invention, the bending bracket may include a first bending block that is arranged at a connection portion of the center portion and the bending portion and forms a bending angle (θ1) between the center portion and the bending portion; and a second bending block that is arranged at a connection portion of the bending portion and the side portion and forms a bending angle (θ2) between the bending portion and the side portion.

[0023] In addition, in an embodiment of the present invention, the bending bracket may further include a reinforcing protrusion formed to protrude from the first and second bending blocks and inserted into the reinforcing groove.

[0024] In addition, in an embodiment of the present invention, a capture support member may be further included, which is arranged along the longitudinal direction (X) on the upper portion of the flight member and extends a sludge capture area in the upward direction (Z) of the flight member.

[0025] In addition, in an embodiment of the present invention, the capture support member may be formed by connecting a plurality of plates at a predetermined angle to each other, and the plurality of plates may be formed with different lengths.

[0026] In addition, in an embodiment of the present invention, the capture support member may include an extension portion formed to extend upward (Z) on one of the plurality of plates.

[0027] In addition, in an embodiment of the present invention, the extension portion may include a center capturing plate extending upward (Z) on a plate disposed above the center portion; and an inclined capturing plate extending upward (Z) on a plate disposed above the bending portion and having a height that gradually increases from the side portion to the center portion.

[0028] In addition, in an embodiment of the present invention, a roller member is further included to increase the mobility of the flight member, and the roller member may include a lower roller unit arranged at the lower portion of the side portion; an upper roller unit arranged at the upper portion of the side portion; and a center roller unit arranged at the lower portion of the center portion.

[0029] Additionally, in an embodiment of the present invention, the length (L) between a pair of rollers arranged in the direction of movement (X) of the upper roller unit can be set to correspond to the length (D) of the flight member bent in the direction of movement (X).

[0030] In addition, in an embodiment of the present invention, the chain connecting member is arranged on the upper portion of the side portion, the upper roller unit is arranged on the outside of the chain connecting member to avoid interference with the endless track of the chain assembly, and the lower roller unit can be arranged at the same position in the vertical direction (Z) with respect to the chain connecting member so that the flight member moves smoothly along the endless track movement of the chain assembly.

[0031] Additionally, in an embodiment of the present invention, the bending portion can be bent in the vertical direction (Z) corresponding to the shape of the bottom portion.

[0032] The sludge collector of the present invention may include a device housing; a sprocket part disposed inside the device housing; a chain assembly connected to the sprocket part and rotating in an endless track shape; and a flight member mounted on the chain assembly to collect sludge accumulated at the bottom of the device housing.

[0068] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The multiple embodiments described below may be applied in duplicate as long as they do not conflict with each other.

[0069]

[0070] Referring to FIGS. 2 to 6, a flight assembly (100) according to an embodiment of the present invention may include a flight member (110), a bending bracket (120), a roller member (130), a chain connection member (170), and a capture support member (180).

[0071] The above flight member (110) can be bent multiple times along the longitudinal direction (Y) to form a wide sludge collection area (S) as disclosed in FIG. 10.

[0072] In an embodiment of the present invention, the flight member (110) can be bent toward the moving direction (X) from the center toward the edge. Here, the moving direction (X) side means the direction in which the flight member (110) moves when connected to the chain assembly.

[0073] The above flight member (110) can form a wide sludge collection area (S) through the above-described bending structure.

[0074] These flight members (110) may include a center portion (111), a bending portion (113), a side portion (115), and a reinforcing groove (117).

[0075] The center portion (111) can form the central side of the flight member (110) and can be arranged in a vertical direction with respect to the direction of movement (X).

[0076] The bending portion (113) can be arranged to be connected to both sides of the center portion (111) and can be bent at a predetermined bending angle (θ1) toward the moving direction (X).

[0077] The side portion (115) can be arranged to be connected to the outer end of the bending portion (113) and can be bent at a predetermined bending angle (θ2).

[0078] Referring to FIG. 3 here, the bending angle (θ2) of the side portion (115) can be arranged perpendicular to the moving direction (X). In this case, as disclosed in FIG. 10, the side portion (115) can also form a sludge collection area (S).

[0079] Or, in another form, the bending angle (θ2) of the side portion (115) may be formed to be larger than the bending angle (θ1) of the bending portion (113) and smaller than the vertical angle (90°) with respect to the moving direction (X). In this case, the side portion (115) is slightly bent toward the moving direction (X), so that the sludge collection area (S) can be slightly expanded.

[0080] The reinforcing groove (117) can be formed concavely in the center portion (111), bending portion (113), or side portion (115) along the longitudinal direction (Y) opposite to the moving direction (X).

[0081] If the surface that collects sludge in the center section (111), bending section (113), or side section (115) is simply a flat surface, the center section (111), bending section (113), or side section (115) may bend due to the weight of the sludge when sweeping and collecting the sludge.

[0082] Especially when used to capture sludge for a long period of time, a load is generated by the continuous weight of sludge, which may cause a decrease in strength and deformation of the flight member (110).

[0083] In order to prevent deformation of the flight member (110), the thickness of the flight member (110) may be increased, but this increases the weight of the flight member (110), which reduces mobility and may put a strain on the chain assembly and sprocket.

[0084] In an embodiment of the present invention, by forming a reinforcing groove (117) that is concavely bent along the longitudinal direction (Y) on the central side of the flight member (110), the strength of the center portion (111), the bending portion (113), or the side portion (115) can be reinforced through structural design. Since the reinforcing groove (117) is formed in the center portion (111), the bending portion (113), or the side portion (115), even when a load due to the weight of sludge is applied, the structural rigidity and durability are increased, so that the structure is not easily deformed.

[0085] In particular, in the embodiment of the present invention, since the flight member (110) is folded multiple times, the sludge collection area (S) is expanded as shown in FIG. 10, and thus the sludge collection weight increases, so the load applied to the flight member (110) becomes greater than that of the conventional structure shown in FIG. 1. However, since the reinforcing groove (117) is formed, the deformation resistance against the load increases.

[0086]

[0087] Meanwhile, a plurality of bending brackets (120) can be spaced apart from each other along the longitudinal direction (X) of the flight member (110), and the flight member (110) can be bent a plurality of times along the longitudinal direction (X).

[0088] The flight member (110) according to an embodiment of the present invention may be manufactured as an integral part in the above-described folded form. Alternatively, the center portion (111), the bending portion (113), and the side portion (115) may be manufactured separately, and the bending bracket (120) may be mounted thereon, and the member may be manufactured to be folded multiple times.

[0089] The above bending bracket (120) may include a first bending block (121), a second bending block (123), and a reinforcing protrusion (125).

[0090] The first bending block (121) is arranged at the connection portion of the center portion (111) and the bending portion (113), and can form a bending angle (θ1) between the center portion (111) and the bending portion (113). In an embodiment of the present invention, the first bending block (121) may include a pair of rectangular bending plates that are attached to each other, and the pair of bending plates may be attached to each other while forming a bending angle (θ1). In addition, the pair of bending plates may be detachably fastened to an end portion of the center portion (111) and an end portion of the bending portion (113) using bolts / nuts, respectively.

[0091] The second bending block (123) is arranged at the connection portion of the bending portion (113) and the side portion (115), and can form a bending angle (θ2) between the bending portion (113) and the side portion (115). In an embodiment of the present invention, the second bending block (123) may include a pair of rectangular bending plates that are attached to each other, and the pair of bending plates may be attached to each other while forming a bending angle (θ2). In addition, the pair of bending plates may be detachably fastened to an end portion of the bending portion (113) and an end portion of the side portion (115) using bolts / nuts, respectively.

[0092] When the manufacturer wants to change the bending angle (θ1) of the center portion (111) and the bending portion (113), he / she can separate the first bending block (121) and replace it with a first bending block (121) formed at a different bending angle. In addition, when the manufacturer wants to change the bending angle (θ2) of the bending portion (113) and the side portion (115), he / she can separate the second bending block (123) and replace it with a second bending block (123) formed at a different bending angle.

[0093] The reinforcing projection (125) can be formed by protruding from the first and second bending blocks (121, 125) and can be inserted into the reinforcing groove (117).

[0094] As described above, the reinforcing groove (117) is formed to increase the structural rigidity of the flight member (110). At this time, the reinforcing projection (125) is inserted into the reinforcing groove (117) and supports the inner surface of the reinforcing groove (117) by contacting it, thereby preventing the reinforcing groove (117) from being deformed.

[0095]

[0096] Meanwhile, referring to FIG. 6, the capture support member (180) is arranged along the longitudinal direction (X) on the upper side of the flight member (110), and the sludge capture area (S) can be expanded in the upward direction (Z) of the flight member (110).

[0097] In an embodiment of the present invention, the capture support member (180) is formed by connecting a plurality of plates at a predetermined angle to each other, and the plurality of plates can be formed with different lengths.

[0098] This capture support member (180) may include a first capture plate (181), a second capture plate (182), a third capture plate (183), a fourth capture plate (184), and an extension (185).

[0099] The first collecting plate (181) may be in the shape of a square plate and may be formed with a shortest first length (E1). The second collecting plate (182) may be in the shape of a square plate and may be formed with a second length (E2) that is longer than the first length (E1). The third collecting plate (183) may be in the shape of a square plate and may be formed with a third length (E3) that is longer than the second length (E2). The fourth collecting plate (184) may be in the shape of a square plate and may be formed with a fourth length (E4) that is longer than the third length (E3).

[0100] The first to fourth capturing plates (181 to 184) can be connected to each other at a 90 degree angle.

[0101] And the first to fourth capturing plates (181 to 184) can be detachably fastened to the upper portion of the flight member (110) with bolts / nuts. Although not shown in the drawing, fastening holes can be formed in the upper portion of the flight member (110) and the first to fourth capturing plates (181 to 184), and they can be fastened to each other with bolts / nuts.

[0102] Alternatively, although not shown in the drawing, fastening holes may be formed in each of the first to fourth capturing plates (181 to 184) and the bending portion (113), and when the bending portion (113) is fastened to the flight member (110) by a bolt / nut, they may be fastened together.

[0103] The manufacturer can select the first to fourth collecting plates (181 to 184) according to the design specifications to expand the sludge collection area (S) in the upward direction (Z) and place them on the upper part of the flight member (110).

[0104] For example, if it is desired to form the sludge collection area (S) low in the upward direction (Z) to avoid interference with other equipment, the third collection plate (183) may be bolted to the upper part of the flight member (110) so that the first collection plate (181) is positioned upward.

[0105] Conversely, if there is no interference with other equipment and a lot of sludge collection is required, and the sludge collection area (S) is to be formed high in the upward direction (Z), the second collection plate (182) may be bolted to the upper part of the flight member (110) so that the fourth collection plate (184) is placed upward.

[0106] Referring to Fig. 9, the extension (185) may be formed to extend upward (Z) on any one of the plurality of plates. Since the extension (185) is intended to expand the sludge collection amount upward (Z), in the embodiment of the present invention, it may be connected to the fourth collection plate (184).

[0107] This extension (185) may include a center collecting plate (186) and an inclined collecting plate (187).

[0108] The center collecting plate (186) can extend upward (Z) to a plate positioned on the upper portion of the center section (111). In an embodiment of the present invention, it can extend to the upper portion of the fourth collecting plate (184).

[0109] The inclined collecting plate (187) may be formed to extend upward (Z) on a plate positioned on the upper portion of the bending portion (113) and to have a height that gradually increases from the side portion (115) to the center portion (111). In an embodiment of the present invention, it may extend to the upper portion of the fourth collecting plate (184).

[0110] In cases where there is no interference with other equipment and a large amount of sludge collection is required, an extension (185) may be placed on the upper portion of the fourth collection plate (184) to expand the sludge collection area (S) in the upward direction (Z). At this time, the extension (185) may be bolted / nut-fastened to the fourth collection plate (184) or may be formed integrally with the fourth collection plate (184).

[0111]

[0112] Meanwhile, a roller member (130) can be placed on the flight member (110) to increase the mobility of the flight member (110).

[0113] Referring to FIGS. 4 and 5a, in an embodiment of the present invention, the roller member (130) may include a lower roller unit (140), an upper roller unit (150), and a center roller unit (160).

[0114] The lower roller unit (140) may be placed at the bottom of the side portion (115). This lower roller unit (140) may include a lower roller bracket (141), a lower roller shaft (143), and a lower roller (145).

[0115] The lower roller bracket (141) can be placed at the bottom of the side portion (115) and can extend to the front / rear side of the side portion (115) based on the moving direction (X).

[0116] A pair of lower roller shafts (143) and lower rollers (145) may be provided, and one lower roller shaft (143) and lower roller (145) may be arranged on the front side of the side part (115), and the other lower roller shaft (143) and lower roller (145) may be arranged on the rear side of the side part (115). That is, a pair of lower rollers (145) support the movement of the flight member (110) on the front / rear sides of the side part (115). At this time, a guide rail (212) may be arranged on the bottom part (211) of the sludge collector (200) to guide the movement of the lower roller (145).

[0117] The upper roller unit (150) can be placed on the upper side of the side section (115).

[0118] This upper roller unit (150) may include an upper roller bracket (151), an upper roller shaft (153), and an upper roller (155).

[0119] The upper roller bracket (151) can be placed on the upper part of the side part (115) and can extend to the front / rear side of the side part (115) based on the moving direction (X).

[0120] The upper roller shaft (153) and the upper roller (155) may be provided as a pair, and one upper roller shaft (153) and the upper roller (155) may be arranged on the front side of the side portion (115), and the other upper roller shaft (153) and the upper roller (155) may be arranged on the rear side of the side portion (115).

[0126] Here, the chain connecting member (170) can be placed on the upper part of the side part (115), and the upper roller unit (150) can be placed on the outside of the chain connecting member (170) to avoid interference with the endless track of the chain assembly.

[0127] And the lower roller unit (140) can be placed at the same position in the vertical direction (Z) with respect to the chain connecting member (170) so that the flight member (110) moves smoothly along the infinite track movement of the chain assembly.

[0128] That is, the lower roller unit (140), the guide rail (212), and the chain assembly are arranged at the same position in the vertical direction (Z), and the lower roller unit (140) moves directly along the guide rail (212) from the lower portion of the side portion (115) connected to the chain assembly, so that the flight member (110) can move smoothly in the movement direction (X) of the chain assembly.

[0129]

[0130] Meanwhile, referring to FIG. 5a, the upper and lower positions of the flight assembly (100) passing through the bottom (211) of the sludge collector (200) according to the infinite track movement of the chain assembly are shown. When passing through the bottom (211) of the sludge collector (200), lower roller units (140) are respectively arranged on the side portions (115) on both sides, and one center roller unit (160) is arranged on the center portion (111) to move along the guide rail (212), so that the flight member (110) can move stably in the moving direction (X) without being overturned.

[0131] However, referring to FIG. 5b, the upper and lower positions of the flight assembly (100) upon return from the upper portion of the sludge collector (200) according to the infinite track movement of the chain assembly are shown. When passing through the upper portion of the sludge collector (200), upper roller units (150) are arranged on each of the side portions (115) on both sides, but the center roller unit (160) is not arranged on the center portion (111). Although not shown in the drawing, there is a guide rail on which the upper roller unit (150) moves on the upper portion of the sludge collector (200).

[0132] As described above, since the chain connecting member (170) is arranged on the side portion (115), the center portion (111), which is bent at a predetermined angle through the bending portion (113) with respect to the side portion (115), is arranged in a state of protruding in the opposite direction of the moving direction (X), and thus may be overturned under a load (F) due to its own weight in the downward direction (Z). In other words, there is a risk of the flight member (110) being overturned when it passes through the upper portion of the sludge collector (200).

[0133] To address this risk, it is necessary to appropriately design the length between a pair of upper rollers (155) corresponding to the bent length of the flight member (110).

[0134] Figures 7a to 8b illustrate the change in length (L) between a pair of upper rollers (155) according to the bent length (D) of the flight member (110).

[0135] First, referring to FIGS. 7a and 7b, when the total bending length (D1) of the center portion (111), bending portion (113), and side portion (115) formed by the first and second bending blocks (121, 123) is short, the length (L1) between a pair of upper rollers (155) can be formed short. To be precise, as disclosed in FIG. 7b, it can be the length (L1) between a pair of upper roller axles (153).

[0136] At this time, the bending length (D1) may be the length between the rear reference line (P1) of the center portion (111) and the front reference line (P2) of the side portion (115) based on the direction of movement (X).

[0137] That is, the length (L1) between a pair of upper rollers (155) is formed to correspond to the length between the rear reference line (P1) of the center portion (111) and the front reference line (P2) of the side portion (115), so that even if it passes the upper portion of the sludge collector (200), the upper rollers (155) arranged on both side portions (115) can sufficiently support the load of the center portion (111). The extension of the length between a pair of upper rollers (155) is the same as extending the length of the upper roller bracket (151) as in Fig. 8b.

[0138] Referring to the following Figures 8a and 8b, when the total bending length (D2) of the center portion (111), bending portion (113), and side portion (115) formed by the first and second bending blocks (121, 123) is long, the length (L2) between a pair of upper rollers (155) can be extended to form it longer. To be precise, as disclosed in Figure 8b, it can be the length (L2) between a pair of upper roller axles (153).

[0139] At this time, the bending length (D2) may be the length between the rear reference line (P1) of the center portion (111) and the front reference line (P2) of the side portion (115) based on the movement direction (X).

[0140] That is, the length (L2) between a pair of upper rollers (155) is extended to correspond to the length between the rear reference line (P1) of the center portion (111) and the front reference line (P2) of the side portion (115), so that even if it passes the upper portion of the sludge collector (200), the upper rollers (155) arranged on both side portions (115) can sufficiently support the load of the center portion (111). The extension of the length between a pair of upper rollers (155) is the same as extending the length of the upper roller bracket (151) as in Fig. 8b.

[0141] In this way, the upper roller unit (150) according to the embodiment of the present invention is designed to correspond to the bending length of the flight member (110), thereby preventing the risk of the flight member (110) overturning even if it passes over the upper part of the sludge collector (200) by the chain assembly.

[0142]

[0143] Meanwhile, the chain connecting member (170) connects the flight member (110) and the chain assembly of the sludge collector (200), and can enable the flight member (110) to move according to the infinite track movement of the chain assembly.

[0144] These chain connecting members (170) may include a link body (171), a link pin (173), and a wing support (175).

[0145] The link body (171) can be connected to the upper part of the side part (115) and can have a shape that extends long in the direction of movement (X).

[0146] The link pin (173) can connect the link body (171) and the chain assembly.

[0147] The wing support (175) may be positioned so as to protrude from the upper portion of the link body (171), and a curved portion may be formed at the portion that contacts the sprocket. Although not shown in the drawing, the wing support (175) may also be provided in the chain assembly applied in the embodiment of the present invention.

[0148] These chain connecting members (170) can be placed on the inside of the upper roller unit (150) in the side section (115).

[0149]

[0150] Meanwhile, referring to FIGS. 11a and 11b, when the bottom part (211) of the sludge collector (200) has a protruding shape, the bending part (113) of the flight assembly (100) can be configured to bend in a downward direction (Z) from the center part (111) to the side part (115).

[0151] And referring to FIGS. 12a and 12b, when the bottom part (211) of the sludge collector (200) has a sunken shape, the bending part (113) of the flight assembly (100) can be configured to bend upward (Z) from the center part (111) to the side part (115).

[0152] That is, in the embodiment of the present invention, the bending portion (113) can be bent in the direction of movement (X) to increase the amount of sludge collected, and can also be bent in the vertical direction (Z) corresponding to the shape of the bottom portion (211) so that the flight assembly (100) can move smoothly on the bottom portion (211).

[0153] In this case, the gap between the bottom part (211) and the flight assembly (100) can be minimized, thereby reducing the sludge from escaping into the space between the bottom part (211) and the flight assembly (100).

[0154]

[0155] Meanwhile, referring to FIGS. 13a and 13b, a flight assembly (100) equipped with a different form of the bending bracket (120) is disclosed.

[0156] Another form of the above bending bracket (120) may be mounted by bolting to the rear of the center portion (111), bending portion (113), and side portion (115). Another form of the above bending bracket (120) may include first and second bending blocks (121, 123) and a support groove (127).

[0157] The first bending block (121) may have a center piece (121a) positioned on the rear side of the center portion (111). In addition, wing pieces (121b) may be positioned on both sides of the center piece (121a), and a pair of wing pieces (121b) may be bolted and connected to the bending portion (113).

[0158] Referring to Fig. 13b, it can be confirmed that the bolt (121f) is fastened, and referring to Fig. 13c, the bolt hole (121e) is disclosed, so that the bolt (121f) can be inserted into the bolt hole (121e) to connect the wing piece (121b) and the bending portion (113). The bolt fastening method can facilitate replacement with a first bending block (121) having a different angle. Here, a bolt hole (111a) to which a center roller bracket (161) is bolt-fastened can be formed on the front of the center portion (111).

[0159] At this time, the center piece (121a) and a pair of wing pieces (121b) can be connected while forming a predetermined bending angle, and as the first bending block (121) is connected to the center portion (111) and the bending portion (113), the center portion (111) and the bending portion (113) can form the above-described bending angle (θ1).

[0160] The second bending block (123) may have one bending piece (123a) bolted to the bending portion (113), and the other bending piece (123b) bolted to the side portion (115). Likewise, the one bending piece (123a) and the other bending piece (123b) may be connected while forming a predetermined bending angle, and as the second bending block (123) is coupled to the bending portion (113) and the side portion (115), the bending portion (113) and the side portion (115) may form the above-described bending angle (θ2).

[0161] The above support groove (127) can be formed concavely in a portion corresponding to the reinforcing groove (117) on the first and second bending blocks (121, 123). Referring to Fig. 13c, a support groove (127) formed concavely on the front surface of the first bending block (121) can be confirmed.

[0162] When the first bending block (121) is bolted to the center portion (111) and the bending portion (113), the reinforcing groove (117) is inserted into the supporting groove (127), and since the supporting groove (127) corresponds to the shape of the reinforcing groove (117), the supporting groove (127) surrounds and supports the outer surface of the reinforcing groove (117).

[0163] Accordingly, since the reinforcing groove (117) formed in the center portion (111) and the bending portion (113) is supported by the support groove (127), the deformation resistance of the center portion (111) and the bending portion (113) can be increased.

[0164] Although not shown in the drawing, a concave support groove (127) is also formed on the front side of the second bending block (123), and a reinforcing groove (117) formed in the bending portion (113) and the side portion (115) can be inserted and supported.

[0165]

[0166] Meanwhile, referring to FIG. 14, a sludge collector (200) according to an embodiment of the present invention may include a device housing (210), a scum collection unit (214), a sludge collection unit (215), a sprocket unit (220), a driving unit (230), a chain assembly (240), and a flight assembly (100).

[0167] The device housing (210) may be a structure with a predetermined space formed inside.

[0168] The sprocket unit (220) may be arranged inside the device housing (210). In an embodiment of the present invention, first to fourth sprockets (221 to 224) may be arranged at predetermined intervals. At this time, the first sprocket (221) may be connected to the drive unit (230) via a drive chain to rotate the chain assembly (240).

[0169] The driving unit (230) is placed on the upper part of the device housing (210) and may be a motor, but is not necessarily limited thereto.

[0170] The chain assembly (240) can be connected to multiple unit chains in an endless track shape and can rotate by engaging with the sprocket part (220).

[0171] According to an embodiment of the present invention, a plurality of flight assemblies (100) are connected to a chain assembly (240) and can rotate in an endless track shape inside the device housing (210) according to the rotation of the chain assembly (240).

[0172] The scum collection unit (214) can be placed adjacent to the water surface at the top of the device housing (210) and can collect and remove scum floating on the water surface.

[0173] The sludge collection unit (215) can be placed at the bottom of the device housing (210) and can collect and remove the sludge captured by the flight assembly (100).

[0174] Meanwhile, sludge may accumulate in the sludge collection unit (215) and, if accumulated in large quantities, form a waterway. While sludge should normally be removed along with water, in this case, a waterway is formed, the accumulated sludge is not removed and only water flows out along the waterway.

[0175] At this time, in the case of the conventional flight (10) disclosed in Fig. 1, since it is a long straight shape only in the longitudinal direction (X), it cannot exhibit the effect of dispersing sludge. Accordingly, the sludge accumulated in the sludge collection unit (215) cannot be dispersed, and thus the water path cannot be removed.

[0176] However, as described above, the flight assembly (100) according to the embodiment of the present invention is bent forward / backward along the direction of movement (X) and has a long front / back shape. Therefore, as disclosed in FIG. 15, when the flight assembly (100) rotates due to the movement of the chain assembly (240), the sludge (S1) is scattered in the direction of the arrow (T), so that the sludge (S1) accumulated in the sludge collection unit (215) is scattered and dispersed, and the water path can be removed. Through this, the sludge can be well discharged together with the water.

[0177]

[0178] The present invention can increase the sludge collection capacity of a flight assembly through the above-described structure. This can improve the sludge treatment performance of a sludge collector.

[0179] Additionally, the movement performance of the flight assembly can be improved. This can improve the operational stability of the flight assembly in the sludge collector, thereby improving equipment operability and reducing maintenance costs.

[0180] The above merely illustrates specific embodiments of the flight assembly and the sludge collector comprising the same.

[0181] Accordingly, it is to be made clear that a person having ordinary skill in the art can easily understand that the present invention can be substituted and modified in various forms without departing from the spirit of the present invention described in the claims below.
