DETAILED DESCRIPTION

[0031] The sewage of the garbage treatment station (garbage transfer station) is usually composed of flushing water and filter press liquor, wherein the flushing water can be discharged to the sewage collection tank through the underground pipe in the non-closed water ditch, and the filter press liquor can be transported to the sewage collection tank through the vacuum sewage suction system.

[0032] However, the non-closed water ditch cannot be sealed, and there is a problem of odor emission. Although the vacuum sewage suction system can be sealed and reduce odor emission, manual docking of the pipeline is required, and automatic sewage collection cannot be realized. 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 easy to overflow, which causes adverse effects on the on-site environment.

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments.

[0037] In addition, if the terms "first", "second" and the like appear, they are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0038] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0039] Please refer to Figure 1 The present embodiment provides a sewage collection system 010 which can be arranged at a garbage disposal station (garbage transfer station) or the like, and is used for collecting sewage such as flushing water and filter liquor.

[0040] 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 between the conveying pipeline of the sewage collection device 100 and the sewage tank 300, and is used for filtering the 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 the silt and dregs in the sewage.

[0041] Optionally, the sewage tank 300 is connected with a sewage discharge pipe 301 for discharging the sewage collected in the sewage tank 300.

[0042] Further, the sewage discharge pipe 301 is connected to the bottom of the sewage tank 300, so as to more smoothly discharge the sewage from the sewage tank 300.

[0043] 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 pipe, so as to discharge the sewage to a collection pool through the pre-buried pipe.

[0044] 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 pipe. Alternatively, in other embodiments, the sewage collection system 010 can not be provided with the filtering device 200, and the sewage collected in the sewage collection device 100 can be directly discharged into the sewage tank 300. Alternatively, in other embodiments, the sewage collected in the sewage collection device 100 can be directly discharged into the pre-buried pipe.

[0045] Please refer to Figure 2 and Figure 3 The sewage collection device 100 of the present 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 to open or shield the sewage inlet 111. When the water receiving tongue 120 opens the sewage inlet 111, the sewage can flow into the sewage collection box 110 from the sewage inlet 111, and when the water receiving tongue 120 shields the sewage inlet 111, the odor can be blocked from escaping from the sewage collection box 110. Through the arrangement of the water receiving tongue 120, on the one hand, when there is no sewage discharged into the sewage collection box 110, the water receiving tongue 120 can be used to shield the sewage inlet 111, so as to improve the problem of odor escaping, and on the other hand, when discharging the sewage into the sewage collection box 110, the water receiving tongue 120 can be used to open the sewage inlet 111, so as to cancel the process of connecting the pipe, which is conducive to realizing the automatic sewage discharge, i.e. improving the efficiency and saving the labor input.

[0046] 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 for opening or shielding the inlet 111; wherein when the 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, so as to ensure that the sewage can reliably flow into the sewage collecting tank 110 through the inlet 111; when there is no sewage discharged into the sewage collecting tank 110, the water receiving tongue body 123 is not pressed by external force, that is, the surface of the water receiving tongue body 123 is not under pressure, and under the counterweight action of the counterweight part 121, the water receiving tongue 120 can keep balance, and then the water receiving tongue body 123 can reliably shield the inlet 111.

[0047] In order to ensure that the water receiving tongue 120 can reliably and automatically 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 is matched with the inner wall of the sewage collecting tank 110 (for example, abutting or clamping, etc.); in this way, when the water receiving tongue body 123 is not pressed by external force, the water receiving tongue body 123 can be reliably driven to rotate to the direction of shielding the inlet 111 by the counterweight part 121 with greater weight, and when the water receiving tongue body 123 rotates to shield the inlet 111, the reliability of the water receiving tongue body 123 shielding the inlet 111 is ensured by the matching of the water receiving tongue body 123 and the sewage collecting tank 110, and the water receiving tongue body 123 is not excessively rotated to the position beyond the inlet 111.

[0048] 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.

[0049] Optionally, the counterweight portion 121 comprises a first counterweight plate 1211 and a second counterweight plate 1212 connected at an included angle, and the connection between the first counterweight plate 1211 and the second counterweight plate 1212 is connected with the pivoting portion 122 and the flapper body 123; when the flapper body 123 is pressed by an external force to a position shielding the dirty inlet 111, the second counterweight plate 1212 is substantially vertically arranged between the first counterweight plate 1211 and the flapper body 123, and the first counterweight plate 1211 and the second counterweight plate 1212 can jointly maintain the stability of the flapper body 123 shielding the dirty inlet 111; when the flapper body 123 is rotated to a position opening the dirty inlet 111 under the pressure of the sewage, the first counterweight plate 1211 and the second counterweight plate 1212 rotate synchronously with the flapper body 123, and the second counterweight plate 1212 rotates with the flapper body 123 to the direction of the dirty inlet 111, so that the weight of the second counterweight plate 1212 can ensure that the flapper body 123 can more reliably rotate to the position opening the dirty inlet 111, that is, when the flapper body 123 rotates to the position opening the dirty inlet 111 by a certain angle under the action of the sewage, the flapper body 123 can reliably rotate to the position opening the dirty inlet 111 under the triple action of its own weight, the pressure of the sewage, and the second counterweight plate 1212, thereby improving the problem that the flapper body 123 cannot be opened due to insufficient weight of the sewage, that is, ensuring that the flapper 120 can reliably automatically open the dirty inlet 111 under the action of the sewage.

[0050] Further, the weight of the first counterweight plate 1211 is greater than the sum of the weights of the second counterweight plate 1212 and the flapper body 123; in this way, when the sewage is discharged, that is, when there is no pressure of the sewage on the flapper body 123, the weight of the first counterweight plate 1211 can be used to reliably reset the second counterweight plate 1212 and the flapper body 123, and to reliably reset the flapper body 123 to shield the dirty inlet 111.

[0051] Optionally, the width from the end of the first counterweight plate 1211 away from the pivoting portion 122 to the pivoting portion 122 is less than the width from the end of the flapper body 123 away from the pivoting portion 122 to the pivoting portion 122, and the width from the end of the second counterweight plate 1212 away from the pivoting portion 122 to the pivoting portion 122 is less than the width from the end of the flapper body 123 away from the pivoting portion 122 to the pivoting portion 122. In this way, when the flapper body 123 is not pressed by an external force, the flapper body 123 can be more reliably and stably positioned at the position shielding the dirty inlet 111 under the counterweight action of the counterweight portion 121.

[0052] Of course, in other embodiments, the distance from the one end of the first counterweight plate 1211 away from the pivot part 122 to the width of the pivot part 122 can also be equal to or greater than the distance from the one end of the water deflector body 123 away from the pivot part 122 to the width of the pivot part 122.

[0053] Optionally, the first counterweight plate 1211 and the water deflector body 123 are connected at an angle, and the angle between them is an obtuse angle. For example, the angle between them is 175°, 160°, 155°, etc. The second counterweight plate 1212 is also connected to the water deflector body 123 at an angle, and the angle between them is smaller than the angle between the first counterweight plate 1211 and the water deflector body 123. For example, the angle can be 90°, 95°, 100°, etc. When the water deflector body 123 blocks the inlet 111, the first counterweight plate 1211 is distributed approximately horizontally, the water deflector body 123 is distributed obliquely, and the height of the one end of the water deflector body 123 connected to the pivot part 122 is higher than the one end of the water deflector body 123 away from the pivot part 122. In this way, when sewage is poured into the water deflector body 123, it can be ensured that the water deflector body 123 under pressure can be reliably rotated to open the inlet 111.

[0054] Of course, in other embodiments, the angle between the water deflector body 123 and the first counterweight plate 1211 can also be 180°. When the water deflector body 123 blocks the inlet 111, both the water deflector body 123 and the first counterweight plate 1211 are distributed approximately horizontally, or both are distributed obliquely, and the height of the one end of the first counterweight plate 1211 away from the pivot part 122 is higher or lower than the height of the one end of the water deflector body 123 away from the pivot part 122.

[0055] In other embodiments, the counterweight part 121 can only include the first counterweight plate 1211. In other embodiments, only the first counterweight plate 1211 can be connected to the pivot part 122.

[0056] It should be understood that in other embodiments, the water deflector 120 can also not realize the opening and closing of the inlet 111 through the distribution of its own weight. For example, the sewage collection device 100 further includes a resilient member (not shown in the figure), such as a torsion spring, which is connected between the water deflector 120 and the sewage collection tank 110. When the water deflector body 123 is rotated by the force applied by the sewage and opens the inlet 111, the resilient member is elastically deformed. When the water deflector body 123 is not pressed by external force, it can be reset to the position of blocking the inlet 111 under the elastic action of the resilient member.

[0057] It should be noted that the water receiving tongue 120 blocks the dirty inlet 111 refers to: the water receiving tongue 120 completely closes the dirty inlet 111 without leaving a gap. Of course, the water receiving tongue 120 blocking the dirty inlet 111 can also refer to: the water receiving tongue 120 blocks most of the dirty inlet 111, and there is a certain gap.

[0058] Optionally, please continue to refer to Figure 2 and Figure 3 , the dirty 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 112 extending to the inside of the sewage collection tank 110, and the pivoting part 122 of the water receiving tongue 120 is rotatably connected with the extension 112; Specifically, the sewage collection tank 110 includes a tank body 117 and a top plate 118 connected to the tank body 117, the top plate 118 is provided with a dirty inlet 111, and the extension 112 is connected with the top plate 118 and located at the dirty inlet 111, and extends to the inner cavity of the tank body 117, and the pivoting part 122 is rotatably connected with the end of the extension 112 away from the top plate 118. In this way, when the water receiving tongue 120 blocks the dirty inlet 111, it is equivalent to the dirty inlet 111 being retracted, which is beneficial to improve the problem of splashing of sewage falling on the water receiving tongue 120 when the sewage is discharged from the dirty inlet 111 into the sewage collection tank 110.

[0059] Further, when the water receiving tongue 120 is located at the position of blocking the dirty inlet 111, the second counterweight plate 1212 is attached to the side of the extension 112 facing the dirty inlet 111; In this way, when the counterweight part 121 drives the water receiving tongue body 123 to rotate to the position of blocking the dirty inlet 111, the extension 112 can be used to block the problem of excessive rotation of the water receiving tongue 120.

[0060] Of course, in other embodiments, when the water receiving tongue 120 blocks the dirty inlet 111, the water receiving tongue body 123 of the water receiving tongue 120 can also be flush with the dirty inlet 111.

[0061] In order to improve the deposition 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 3 In this embodiment, the sewage collection device 100 further comprises a stirring assembly 130, and the stirring assembly 130 is assembled in the sewage collection tank 110. For example, the stirring assembly 130 is assembled at the top of the sewage collection tank 110 (i.e. the top plate 118) and extends into the sewage collection tank 110; the stirring assembly 130 is used to stir the sewage collected in the sewage collection tank 110, so as to improve the problem of deposition of silt, dregs and the like in the sewage at the bottom of the sewage collection tank 110.

[0062] Optionally, please refer to Figure 4The stirring assembly 130 comprises a stirring motor 131, a stirring rod 132 and stirring blades 133. The stirring motor 131 is arranged on the top of the sewage collecting tank 110 (i.e. the top plate 118). The stirring rod 132 is in driving connection with the output shaft of the stirring motor 131 and extends into the sewage collecting tank 110. 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.

[0063] Of course, in other embodiments, the stirring assembly 130 can also be arranged on the bottom or the sidewall of the sewage collecting tank 110, i.e. the stirring motor 131 can be arranged on the bottom or the sidewall of the sewage collecting tank 110, and the stirring rod 132 in driving connection with the stirring motor 131 extends into the sewage collecting tank 110 from the bottom or the sidewall of the sewage collecting tank 110.

[0064] Optionally, the stirring blades 133 are distributed on the end of the stirring rod 132 away from the stirring motor 131, so that the stirring blades 133 can be as close to the bottom of the sewage collecting tank 110 as possible, so as to fully stir the sewage in the sewage collecting tank 110 and improve the deposition of the sand, dregs and the like.

[0065] Of course, in other embodiments, the stirring assembly 130 comprises a plurality of stirring blades 133, and the plurality of stirring blades 133 are connected with the stirring rod 132 and sequentially and spacedly distributed along the length extension direction of the stirring rod 132.

[0066] In other embodiments, the sewage collecting device 100 can also not be provided with the stirring assembly 130.

[0067] In order to transport the sewage in the sewage collecting tank 110 to the filtering device 200 for filtering, please refer 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, and the other end of the suction pipeline 140 is connected with the filtering device 200. The suction pipeline 140 is used for sucking the sewage in the sewage collecting tank 110 from the suction inlet 143 and transporting the sewage to the filtering device 200.

[0068] Optionally, the suction inlet 143 is arranged adjacent to the bottom of the sewage collecting tank 110, so as to facilitate sucking the solid matters such as the sand and the dregs in the sewage and reducing the deposition of the sand and the dregs in the sewage collecting tank 110.

[0069] It should be noted that, since the sewage collection tank 110 is provided with the stirring assembly 130, the silt, dregs and the like can be uniformly mixed in the sewage, and the problem of the silt, dregs and the like blocking the suction inlet 143 of the suction pipeline 140 can be improved.

[0070] Of course, in other embodiments, the suction inlets 143 can also be arranged to be distributed in the middle of the sewage collection tank 110.

[0071] In order to improve the problem that the sewage collection device 100 cannot smoothly complete the corresponding collection work due to the blockage failure of the suction pipeline 140, please continue to refer to Figure 4 The sewage collection tank 110 of the embodiment has two water storage cavities 113 inside, and the two water storage cavities 113 are communicated through the overflow space 114. Correspondingly, the sewage collection device 100 includes two stirring assemblies 130 and two suction pipelines 140, and the water storage cavity 113, the stirring assembly 130 and the suction pipeline 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 pipeline 140, and the suction inlet 143 of each suction pipeline 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 pipeline 140 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 pipeline 140 in the other water storage cavity 113, so as to improve the problem that the sewage in the sewage collection tank 110 cannot be sucked out and overflow, and improve the operation stability of the sewage collection system 010; only when the corresponding suction pipelines 140 of the two water storage cavities 113 all fail, it is necessary to stop and maintain.

[0072] 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 pipelines 140 also increases accordingly.

[0073] Optionally, the suction inlet 143 of the suction pipeline 140 is configured to be distributed towards the axis of the water storage cavity 113. In this way, the silt, dregs and the like in the sewage can be more reliably sucked in, which is beneficial to reduce the accumulation of silt, dregs and the like in the water storage cavity 113.

[0074] Please continue to refer to Figure 4In 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, so as 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 in particular, the top end of the partition 150 is spaced apart from the top plate 118 of the sewage collection tank 110, so as to form an overflow space 114.

[0075] The connection mode of the partition 150 and the sewage collection tank 110 includes but is not limited to one-piece forming, welding, and riveting.

[0076] Further, the partition 150 includes two first guide surfaces 151 spaced apart from each other, and the two first guide surfaces 151 correspond to the two water storage cavities 113 respectively. The two first guide surfaces 151 are both inclined, and the distance between the two first guide surfaces 151 gradually decreases from one end close to the bottom of the sewage collection tank 110 to one end close to the top of the sewage collection tank 110 (i.e., the top plate 118), that is, the distance between the two first guide surfaces 151 gradually decreases in the direction from the bottom of the sewage collection tank 110 to the top of the sewage collection tank 110, so that the two first guide surfaces 151 form an inverted “V” shape. The one end of the two first guide surfaces 151 away from the bottom of the sewage collection tank 110 is connected to each other, that is, one end of the first guide surface 151 extends to the bottom of the water storage cavity 113, and the other end of the first guide surface 151 is spaced apart from the top of the sewage collection tank 110 (i.e., the top plate 118), so as to form the overflow space 114. In this way, it is more convenient for the sewage to overflow between the two water storage cavities 113.

[0077] Of course, in other embodiments, the one end of the two first guide surfaces 151 away from the bottom of the sewage collection tank 110 can also be connected by a horizontal drainage surface.

[0078] In other embodiments, the partition 150 can not be provided with the first guide surface 151.

[0079] Further, the sewage collection tank 110 has two second guide surfaces 115, and the second guide surfaces 115 are inner walls of the sewage collection tank 110.

The distance between the corresponding first guide surface 151 and the second guide surface 115 gradually increases from the bottom to the top of the water storage cavity 113, so that the caliber of the water storage cavity 113 gradually increases from the bottom to the top. In this way, the water storage cavity 113 can form a flared structure, which is beneficial to increase the water storage capacity.

[0080] It should be understood that in other embodiments, the sewage collection tank 110 can not be provided with the second guide surface 115, i.e., the inner wall of the sewage collection tank 110 opposite to the first guide surface 151 can be provided as a vertical wall surface.

In this way, the part of the suction pipe 140 extending into the water storage cavity 113 can be improved to interfere with the agitation of the sewage by the stirring assembly 130, thereby ensuring that the sand, dregs and the like can be more uniformly mixed into the sewage.

[0083] Of course, in other embodiments, the second pipe 142 can also be attached to the second guide surface 115.

[0084] The angle between the first pipe 141 and the second pipe 142 can be set as needed, for example: 135°, 145°, 160°, etc., which is not specifically limited here and will not be described one by one.
