DETAILED DESCRIPTION

[0030] The sewage of a garbage disposal station (for example, a garbage transfer station) is usually composed of flushing water and filter press liquor, wherein the flushing water can be discharged to a sewage collection tank through a non-closed water ditch and the filter press liquor can be delivered to the sewage collection tank through a vacuum sewage suction system.

[0031] However, the non-closed water ditch cannot be sealed and has the problem of odor emission. Although the vacuum sewage suction system can be sealed to reduce odor emission, manual docking of the pipeline is required and automatic sewage collection cannot be achieved. In addition, the sewage collection system provided by the related art is easily blocked by silt and dregs, so that the system cannot normally collect sewage and the sewage is prone to overflow, which has an adverse effect on the on-site environment.

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0036] In addition, if the terms "first", "second" and the like appear, they are only used for distinction in description and cannot be understood as indicating or implying relative importance.

[0037] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0038] Referring to Figure 1 The embodiment provides a sewage collection system 010 which can be arranged at a waste treatment station (for example, a waste transfer station) or the like, and is used for collecting sewage such as flushing water and filter liquor.

[0039] The sewage collection system 010 comprises a sewage collection device 100, a filtering device 200 and a sewage tank 300; the sewage collection device 100 is used for collecting sewage; the filtering device 200 is arranged in a conveying pipeline between the sewage collection device 100 and the sewage tank 300, and is used for filtering sewage output from the sewage collection device 100, and then conveying the filtered sewage to the sewage tank 300, so as to reduce the blockage of the pipeline by mud and dregs in the sewage.

[0040] Optionally, the sewage tank 300 is connected with a sewage discharge pipe 301, and is used for discharging sewage collected in the sewage tank 300.

[0041] Further, the sewage discharge pipe 301 is connected to the bottom of the sewage tank 300, so that the sewage can be discharged from the sewage tank 300 more smoothly.

[0042] It should be understood that the end of the sewage discharge pipe 301 away from the sewage tank 300 can be connected with a pre-buried pipeline, so as to discharge the sewage to a collection pool through the pre-buried pipeline.

[0043] In other embodiments, the sewage collection system 010 can not be provided with the sewage tank 300, and the sewage filtered by the filtering device 200 can be directly discharged into the pre-buried pipeline.

[0044] Referring to Figure 2 and Figure 3 The sewage collection device 100 of the embodiment comprises a sewage collection box 110 and a water receiving tongue 120; the sewage collection box 110 is provided with a sewage inlet 111; the water receiving tongue 120 is movably connected with the sewage collection box 110, and the water receiving tongue 120 is located at the sewage inlet 111, and is used for opening or shielding the sewage inlet 111; when the water receiving tongue 120 opens the sewage inlet 111, sewage can flow into the sewage collection box 110 from the sewage inlet 111; when the water receiving tongue 120 shields the sewage inlet 111, the water receiving tongue 120 can block the escape of odor from the sewage collection box 110. Through the arrangement of the water receiving tongue 120, on the one hand, the water receiving tongue 120 can shield the sewage inlet 111 when there is no sewage discharged into the sewage collection box 110, so as to improve the problem of odor escaping; on the other hand, when sewage is discharged into the sewage collection box 110, the water receiving tongue 120 can open the sewage inlet 111, and the process of connecting the pipeline is cancelled, which is beneficial to realize automatic sewage discharge, that is, the efficiency is improved, and the labor input is saved.

[0045] Further, the water receiving tongue 120 is rotatably connected with the sewage collecting tank 110, and is balanced by the weight of the water receiving tongue 120, so that the water receiving tongue 120 can stably keep the state of shielding the inlet 111 under the action of no external force. For example, the water receiving tongue 120 comprises a counterweight part 121, a pivot part 122 and a water receiving tongue body 123, the counterweight part 121 and the water receiving tongue body 123 are connected through the pivot part 122, the pivot part 122 is rotatably connected with the sewage collecting tank 110, and the water receiving tongue body 123 is used to open or shield the inlet 111. When sewage is discharged into the sewage collecting tank 110, the sewage falls on the water receiving tongue body 123 to exert pressure on the water receiving tongue body 123, so that the water receiving tongue body 123 rotates around the rotation axis of the pivot part 122 to open the inlet 111, thereby ensuring that the sewage can reliably flow into the sewage collecting tank 110 through the inlet 111. When no sewage is discharged into the sewage collecting tank 110, the water receiving tongue body 123 is not pressed by external force, i.e. the surface of the water receiving tongue body 123 is not under pressure, and the counterweight part 121 can balance the water receiving tongue 120, and the water receiving tongue body 123 can reliably shield the inlet 111.

[0046] In order to ensure that the water receiving tongue 120 can reliably rotate to the position of shielding the inlet 111, the weight of the counterweight part 121 is greater than the weight of the water receiving tongue body 123, and when the water receiving tongue body 123 shields the inlet 111, the end of the water receiving tongue body 123 away from the pivot part 122 abuts against the inner wall of the sewage collecting tank 110. In this way, when the water receiving tongue body 123 is not pressed by external force, the counterweight part 121 with greater weight can reliably drive the water receiving tongue body 123 to rotate to the direction of shielding the inlet 111, and when the water receiving tongue body 123 rotates to shield the inlet 111, the abutment between the water receiving tongue body 123 and the sewage collecting tank 110 ensures the reliability of the water receiving tongue body 123 shielding the inlet 111, and the water receiving tongue body 123 will not excessively rotate to a position beyond the inlet 111.

[0047] Of course, in other embodiments, the weight of the counterweight part 121 can also be equal to the weight of the water receiving tongue body 123.

[0048] Further, when the water receiving tongue body 123 shields the inlet 111, the water receiving tongue body 123 is inclined, and the height of the end of the water receiving tongue body 123 connected with the pivot part 122 is higher than the height of the end of the water receiving tongue body 123 away from the pivot part 122. In this way, when the sewage is poured on the water receiving tongue body 123, it can be ensured that the water receiving tongue body 123 under pressure can reliably rotate to open the inlet 111.

[0049] Of course, in other embodiments, when the water receiving tongue 120 shields the inlet 111, the water receiving tongue body 123 of the water receiving tongue 120 can also be flush with the inlet 111.

[0050] It should be understood that in other embodiments, the water receiving tongue 120 can also achieve the opening and closing of the sewage inlet 111 without the distribution of its own weight; for example, the sewage collection device 100 further comprises a resilient member (not shown in the figure), for example, a torsion spring, which is connected between the water receiving tongue 120 and the sewage collection tank 110. When the water receiving tongue body 123 is rotated by the force applied by the sewage and the sewage inlet 111 is opened, the resilient member is elastically deformed. When the water receiving tongue body 123 is not pressed by external force, it can be reset to the position of blocking the sewage inlet 111 under the elastic action of the resilient member; or the sewage collection device 100 further comprises a driving member, for example, a motor (not shown in the figure), which is assembled on the sewage collection tank 110 and is in transmission connection with the water receiving tongue 120, for driving the water receiving tongue 120 to rotate to open or block the sewage inlet 111.

[0051] It should be understood that in other embodiments, the connection between the water receiving tongue 120 and the sewage collection tank 110 can also be sliding connection, so as to open or block the sewage inlet 111 by sliding the water receiving tongue 120.

[0052] It should be noted that the above-mentioned water receiving tongue 120 blocking the sewage inlet 111 means that the water receiving tongue 120 completely closes the sewage inlet 111 without leaving any gap. Of course, the water receiving tongue 120 blocking the sewage inlet 111 can also mean that the water receiving tongue 120 blocks most of the sewage inlet 111, leaving a certain gap.

[0053] Optionally, please continue to refer to Figure 2 and Figure 3 The sewage inlet 111 is arranged at the top of the sewage collection tank 110, and the top wall of the sewage collection tank 110 is connected with an extension member 112 extending to the inside of the sewage collection tank 110, and the pivot connection part 122 of the water receiving tongue 120 is in rotary connection with the extension member 112; specifically, the sewage collection tank 110 comprises a tank body 117 and a top plate 118 connected to the tank body 117, the top plate 118 is provided with the sewage inlet 111, and the extension member 112 is connected with the top plate 118 and located at the sewage inlet 111, and extends to the inner cavity of the tank body 117, and the pivot connection part 122 is rotatably connected with the end of the extension member 112 away from the top plate 118. In this way, when the water receiving tongue 120 blocks the sewage inlet 111, it is equivalent to the inward retraction of the sewage inlet 111, which is beneficial to improve the problem of splashing of sewage dropping on the water receiving tongue 120 when the sewage is discharged from the sewage inlet 111 into the sewage collection tank 110.

[0054] In order to improve the sedimentation of silt, dregs and the like in the sewage in the sewage collection tank 110, so as to reduce the cleaning frequency of the sewage collection tank 110; please refer to Figure 2 and Figure 3In the embodiment, the sewage collecting device 100 further comprises a stirring assembly 130, the stirring assembly 130 is assembled to the sewage collecting tank 110, for example, the stirring assembly 130 is assembled to the top (i.e. the top plate 118) of the sewage collecting tank 110 and extends into the sewage collecting tank 110; the stirring assembly 130 is used to stir the sewage collected in the sewage collecting tank 110, so as to improve the problem that the silt, dregs and the like in the sewage are deposited at the bottom of the sewage collecting tank 110.

[0055] Optionally, referring to Figure 4 , the stirring assembly 130 comprises a stirring motor 131, a stirring rod 132 and stirring blades 133, the stirring motor 131 is assembled to the top (i.e. the top plate 118) of the sewage collecting tank 110, the stirring rod 132 is in transmission connection with the output shaft of the stirring motor 131 and extends into the sewage collecting tank 110, and the stirring blades 133 are connected with the stirring rod 132 and located in the sewage collecting tank 110; when the stirring motor 131 drives the stirring rod 132 to rotate, the stirring rod 132 drives the stirring blades 133 to rotate, so as to stir the sewage collected in the sewage collecting tank 110 by the stirring blades 133.

[0056] Of course, in other embodiments, the stirring assembly 130 can also be assembled to the bottom or the side wall of the sewage collecting tank 110, that is, the stirring motor 131 can be assembled to the bottom or the side wall of the sewage collecting tank 110, and the stirring rod 132 in transmission connection with the stirring motor 131 extends into the sewage collecting tank 110 from the bottom or the side wall of the sewage collecting tank 110.

[0057] Optionally, the stirring blades 133 are distributed at the end of the stirring rod 132 away from the stirring motor 131, so that the stirring blades 133 can be as close as possible to the bottom of the sewage collecting tank 110, so as to fully stir the sewage in the sewage collecting tank 110 and improve the problem of deposition of silt, dregs and the like.

[0058] Of course, in other embodiments, the stirring assembly 130 comprises a plurality of stirring blades 133, the plurality of stirring blades 133 are connected with the stirring rod 132 and are sequentially and spacedly distributed along the length extension direction of the stirring rod 132.

[0059] In other embodiments, the sewage collecting device 100 can also not be configured with the stirring assembly 130.

[0060] In order to transport the sewage in the sewage collecting tank 110 to the filtering device 200 for filtering; referring to Figure 4 , the sewage collecting device 100 of the embodiment further comprises a suction pipeline 140, one end of the suction pipeline 140 is provided with a suction inlet 143, the other end of the suction pipeline 140 is connected with the filtering device 200, and the suction pipeline 140 is used to suck the sewage in the sewage collecting tank 110 from the suction inlet 143 and transport the sewage to the filtering device 200.

[0061] Optionally, the suction port 143 is arranged adjacent to the bottom of the sewage collecting tank 110, so that the solid matters such as silt and dregs in the sewage can be sucked in together, and the deposition of the silt and dregs in the sewage collecting tank 110 can be reduced.

[0062] It should be noted that, since the sewage collecting tank 110 is provided with the stirring assembly 130, the silt and dregs can be uniformly mixed in the sewage, and the problem of the silt and dregs blocking the suction port 143 of the suction pipe 140 can be improved.

[0063] Of course, in other embodiments, the suction port 143 can also be arranged to be distributed in the middle of the sewage collecting tank 110.

[0064] In order to improve the problem that the sewage collecting device 100 cannot smoothly complete the corresponding collection work due to the blockage failure of the suction pipe 140, please continue to refer to Figure 4 The sewage collecting tank 110 of the present embodiment has two water storage cavities 113, and the two water storage cavities 113 are communicated through the overflow space 114. Correspondingly, the sewage collecting device 100 includes two stirring assemblies 130 and two suction pipes 140, and the water storage cavity 113, the stirring assembly 130 and the suction pipe 140 are arranged one by one, that is, the sewage in each water storage cavity 113 can be stirred by the corresponding stirring assembly 130, and the sewage in each water storage cavity 113 can be transported to the filtering device 200 by the corresponding suction pipe 140, and the suction port 143 of each suction pipe 140 is arranged close to the bottom of the corresponding water storage cavity 113. In this way, the sewage between the two water storage cavities 113 can flow through the overflow space 114, and when the corresponding suction pipe 140 arranged in one of the water storage cavities 113 fails, the sewage in the water storage cavity 113 can flow into the other water storage cavity 113 through the overflow space 114, and be sucked out through the corresponding suction pipe 140 in the other water storage cavity 113, so as to improve the problem that the sewage in the sewage collecting tank 110 cannot be sucked out and overflow, and improve the operation stability of the sewage collecting system 010; only when the corresponding suction pipes 140 arranged in the two water storage cavities 113 both fail, it is necessary to stop and maintain.

[0065] It should be understood that, in other embodiments, the number of water storage cavities 113 can also be one, three, four, etc.; in the embodiment in which the number of water storage cavities 113 is greater than two, the number of separators 150, stirring assemblies 130 and suction pipes 140 also increases accordingly.

[0066] Optionally, the suction inlet 143 of the suction pipe 140 is configured to be distributed towards the axis of the water storage cavity 113. In this way, the solid matter such as silt and dregs in the sewage can be more reliably sucked in, which is conducive to reducing the accumulation of the solid matter such as silt and dregs in the water storage cavity 113.

[0067] Please continue to refer to Figure 4 In the embodiment, the sewage collection tank 110 is provided with a partition 150, and the bottom end of the partition 150 is connected to the bottom of the sewage collection tank 110 to divide the inner cavity of the sewage collection tank 110 into two water storage cavities 113 by the partition 150. The top end of the partition 150 is spaced apart from the top of the sewage collection tank 110, and specifically, the top end of the partition 150 is spaced apart from the top plate 118 of the sewage collection tank 110 to form an overflow space 114.

[0068] The connection mode of the partition 150 and the sewage collection tank 110 includes but is not limited to one-piece forming, welding, riveting.

The water storage assembly 162 is connected to the water storage cavity 113 through the water inlet pipe 163, so that the water stored in the water storage assembly 162 can be delivered into the water storage cavity 113 through the water inlet pipe 163 for cleaning. The water storage assembly 162 includes but is not limited to a water storage tank and a water storage ditch.

[0073] Optionally, the water inlet pipe 163 is further provided with an on-off valve (not shown in the figure), so as to control the opening and closing of the water inlet pipe 163, so that the flushing water can be delivered into the water storage cavity 113 only when the water storage cavity 113 needs to be cleaned.

[0074] Please refer to Figure 6 and Figure 7 The filtering device 200 of the embodiment comprises a filtering tank 210 and a filtering screen 220. The filtering tank 210 has a filtering cavity 211. One end of the suction pipeline 140 away from the suction port 143 is connected with the filtering tank 210 and communicates the water storage cavity 113 and the filtering cavity 211, so that the sewage sucked from the water storage cavity 113 can enter the filtering cavity 211. The filtering screen 220 is arranged in the filtering cavity 211 and is used to filter the sewage entering the filtering cavity 211, so as to block the large-particle silt, plastic and other sundries from flowing to the downstream sewage tank 300, thereby improving the problem of the downstream pipeline being blocked.

[0075] Further, the filtering screen 220 is arranged along the vertical direction, so as to divide the filtering cavity 211 into a filtering residue cavity 212 and a filtering liquid cavity 213 distributed along the horizontal direction. The suction pipeline 140 communicates with the filtering residue cavity 212, the filtering liquid cavity 213 communicates with the sewage tank 300, and the sewage entering the filtering residue cavity 212 is filtered by the filtering screen 220, so that the filtering residue is left in the filtering residue cavity 212 and the filtering liquid enters the filtering liquid cavity 213 and flows into the sewage tank 300 through the filtering liquid cavity 213.

[0076] Optionally, the filtering screen 220 extends along the vertical direction, so that the filtering residue cavity 212 and the filtering liquid cavity are distributed along the horizontal direction. Of course, in other embodiments, the filtering screen 220 can also be arranged at an angle with the vertical direction, for example, the extending direction of the filtering screen 220 can be different from the vertical direction by 1°, 3°, etc., which is not limited here.

[0077] The connecting mode of the filtering screen 220 and the inner wall of the filtering tank 210 includes but is not limited to one-piece forming, plug-in, connecting with bolts and other fasteners.

[0078] Please refer to Figure 6 The bottom of the filtering tank 210 of the embodiment is provided with a filtering residue outlet 214.
