DETAILED DESCRIPTION

[0037] The sewage from a garbage treatment station (e.g., a garbage transfer station) usually consists of flushing water and filtrate, wherein the flushing water can usually be discharged to a sewage collection tank through a concealed pipe in a non-enclosed ditch, while the filtrate can be transported to the sewage collection tank through a vacuum suction system.

[0038] However, since the non-enclosed drain cannot be sealed, there is a problem of odor leakage. Although the vacuum sewage suction system can be sealed to reduce the odor leakage, it requires manual connection of pipes and cannot achieve automatic sewage collection. In addition, the sewage collection system provided by the relevant technology is easily blocked by mud and slag, resulting in the system being unable to collect sewage normally, and the sewage is easy to overflow, causing adverse effects on the on-site environment.

[0039] Moreover, whether it is the non-enclosed ditch provided by the relevant technology or the enclosed vacuum sewage suction system, there is still the problem that solid matter such as mud, slag and other solids in the sewage are easily accumulated in the dead corners of the ditch or water tank. It is easy for the mud, slag and other solids to accumulate more and more, eventually leading to pipe blockage, sewage cannot be discharged smoothly, and sewage overflows and pollutes the environment.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0043] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0045] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0046] Please refer to Figure 1 The present embodiment provides a sewage collection system 010, which can be set up in a garbage disposal station (eg, a garbage transfer station) and the like, and is used to collect sewage such as flushing water and filtrate.

[0047] The sewage collection system 010 includes a sewage collection device 100, a filtering device 200 and a sewage tank 300; the sewage collection device 100 is used to collect sewage; the filtering device 200 is arranged in the conveying pipeline between the sewage collection device 100 and the sewage tank 300, and is used to filter the sewage output from the sewage collection device 100 and then convey it to the sewage tank 300, so as to reduce the blockage of the pipeline by mud, slag, etc. in the sewage.

[0048] Optionally, the sewage tank 300 is connected to a sewage pipe 301 for discharging the sewage collected in the sewage tank 300 .

[0049] Furthermore, the sewage pipe 301 is connected to the bottom of the sewage tank 300 so as to discharge the sewage from the sewage tank 300 more smoothly.

[0050] It should be understood that one end of the sewage pipe 301 away from the sewage tank 300 can be connected to a pre-buried pipeline to discharge the sewage into the collection tank through the pre-buried pipeline.

[0051] In other embodiments, the sewage collection system 010 may not be provided with a sewage tank 300, and the sewage filtered by the filter device 200 may be directly discharged into the pre-buried pipe. Alternatively, in other embodiments, the sewage collection system 010 may not be provided with a filter device 200, and the sewage in the sewage collection device 100 may be directly transported to the sewage tank 300 and discharged through the sewage tank 300.

[0052] Please refer to Figure 2 and Figure 3 The sewage collection device 100 of this embodiment includes 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 to the sewage collection box 110, and the water receiving tongue 120 is located at the sewage inlet 111, and is used to open or cover 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 covers the sewage inlet 111, it can prevent odor from escaping from the sewage collection box 110. By setting the water inlet tongue 120, on the one hand, when there is no sewage discharged into the sewage collection box 110, the water inlet tongue 120 can be used to cover the sewage inlet 111 to improve the problem of odor emission. On the other hand, when discharging sewage into the sewage collection box 110, the water inlet tongue 120 is used to open the sewage inlet 111, eliminating the process of connecting the pipeline, which is conducive to realizing automated sewage discharge, thereby improving efficiency and saving manpower investment.

[0053] Furthermore, the water receiving tongue 120 is rotatably connected to the sewage collection tank 110, and through the weight distribution of the water receiving tongue 120, the water receiving tongue 120 can be stably maintained in a state of covering the sewage inlet 111 when not affected by external forces; exemplary: the water receiving tongue 120 includes a counterweight portion 121, a pivot portion 122 and a water receiving tongue body 123, the counterweight portion 121 and the water receiving tongue body 123 are connected by the pivot portion 122, the pivot portion 122 is rotatably connected to the sewage collection tank 110, and the water receiving tongue body 123 is used to open or cover the sewage inlet 111; wherein, when discharging sewage into the sewage collection tank 110 When sewage is discharged into the sewage collection tank 110, the water receiving tongue body 123 is not pressed by an external force, that is, there is no pressure on the surface of the water receiving tongue body 123. Under the counterweight action of the counterweight part 121, the water receiving tongue 120 can be kept balanced, that is, the water receiving tongue body 123 can be reliably rotated and reset to block the sewage inlet 111.

[0054] In order to ensure that the water receiving tongue 120 can reliably and automatically rotate to the position covering the sewage inlet 111; the weight of the counterweight part 121 is configured to be greater than the weight of the water receiving tongue body 123, and when the water receiving tongue body 123 covers the sewage 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 box 110; in this way, when the water receiving tongue body 123 is not pressed by an external force, the counterweight part 121 with a heavier weight can reliably drive the water receiving tongue body 123 to rotate in the direction of covering the sewage inlet 111, and when the water receiving tongue body 123 rotates to cover the sewage inlet 111, the abutment between the water receiving tongue body 123 and the sewage collecting box 110 ensures the reliability of the water receiving tongue body 123 covering the sewage inlet 111, and does not excessively rotate to the position beyond the covering of the sewage inlet 111.

[0055] Of course, in other embodiments, the weight of the counterweight portion 121 may also be equal to the weight of the water receiving tongue body 123 .

[0056] Optionally, the counterweight portion 121 includes a first counterweight plate 1211 and a second counterweight plate 1212 connected at an angle, and the connection between the first counterweight plate 1211 and the second counterweight plate 1212 is connected to the pivot portion 122 and the water receiving tongue body 123; when the water receiving tongue body 123 is not subjected to pressure from an external force and is located at a position that blocks the sewage inlet 111, the second counterweight plate 1212 is roughly erected between the first counterweight plate 1211 and the water receiving tongue body 123, and the first counterweight plate 1211 and the second counterweight plate 1212 can jointly maintain the stability of the water receiving tongue body 123 blocking the sewage inlet 111; when the water receiving tongue body 123 is subjected to pressure from sewage and rotates toward the position of opening the sewage inlet 111, the first counterweight plate 1211 and the second counterweight plate 1212 rotate with the sewage inlet 111. The water tongue body 123 rotates synchronously, and the second counterweight plate 1212 rotates with the water receiving tongue body 123 toward the sewage inlet 111. In this way, the weight of the second counterweight plate 1212 can be used to ensure that the water receiving tongue body 123 can more reliably rotate toward the position of opening the sewage inlet 111, that is, when the water receiving tongue body 123 rotates a certain angle toward the direction of opening the sewage inlet 111 under the action of sewage, the water receiving tongue body 123 can reliably rotate toward the direction of opening the sewage inlet 111 under the triple action of its own weight, the pressure applied by the sewage, and the second counterweight plate 1212, thereby improving the problem of opening the water receiving tongue body 123 due to insufficient weight of the sewage, that is, ensuring that the water receiving tongue 120 can reliably and automatically open the sewage inlet 111 under the action of sewage.

[0057] Furthermore, the weight of the first counterweight plate 1211 is greater than the sum of the weights of the second counterweight plate 1212 and the water receiving tongue body 123; in this way, when sewage discharge is completed, that is, when no sewage applies pressure to the water receiving tongue body 123, the weight of the first counterweight plate 1211 can be used to drive the second counterweight plate 1212 and the water receiving tongue body 123 to be reliably reset, and the water receiving tongue body 123 can be reliably reset to block the sewage inlet 111.

[0058] Optionally, the width from one end of the first counterweight plate 1211 away from the pivotal portion 122 to the pivotal portion 122 is smaller than the width from one end of the water receiving tongue body 123 away from the pivotal portion 122 to the pivotal portion 122, and the width from one end of the second counterweight plate 1212 away from the pivotal portion 122 to the pivotal portion 122 is smaller than the width from one end of the water receiving tongue body 123 away from the pivotal portion 122 to the pivotal portion 122. In this way, when the water receiving tongue body 123 is not subjected to external pressure, it is ensured that the water receiving tongue body 123 can be more reliably stabilized at a position that blocks the sewage inlet 111 under the counterweight action of the counterweight portion 121.

[0059] Of course, in other embodiments, the width from one end of the first counterweight plate 1211 away from the pivotal portion 122 to the pivotal portion 122 may also be equal to or greater than the width from one end of the water receiving tongue body 123 away from the pivotal portion 122 to the pivotal portion 122. In other embodiments, the width from one end of the second counterweight plate 1212 away from the pivotal portion 122 to the pivotal portion 122 may also be equal to or greater than the width from one end of the water receiving tongue body 123 away from the pivotal portion 122 to the pivotal portion 122.

[0060] Optionally, the first counterweight plate 1211 and the water receiving tongue body 123 are connected at an angle, and the angle between the two is an obtuse angle. For example, the angle between the two is 175°, 160°, 155°, etc.; the second counterweight plate 1212 is also connected to the water receiving tongue body 123 at an angle, and the angle between the two is smaller than the angle between the first counterweight plate 1211 and the water receiving tongue body 123, for example, it can be: 90°, 95°, 100°, etc.; when the water receiving tongue body 123 blocks the sewage inlet 111, the first counterweight plate 1211 is roughly horizontally distributed, the water receiving tongue body 123 is inclined, and the height of the end of the water receiving tongue body 123 connected to the pivot 122 is higher than the end of the water receiving tongue body 123 away from the pivot 122. In this way, when sewage is poured into the water receiving tongue body 123, it can be ensured that the pressurized water receiving tongue body 123 can be reliably rotated to open the sewage inlet 111.

[0061] Of course, in other embodiments, the angle between the water receiving tongue body 123 and the first counterweight plate 1211 can also be 180°. When the water receiving tongue body 123 blocks the sewage inlet 111, the water receiving tongue body 123 and the first counterweight plate 1211 are both roughly horizontally distributed, or both are inclinedly distributed, and the height of the end of the first counterweight plate 1211 away from the pivotal portion 122 is higher or lower than the height of the end of the water receiving tongue body 123 away from the pivotal portion 122.

[0062] In other embodiments, the counterweight portion 121 may only include the first counterweight plate 1211 ; in other embodiments, only the first counterweight plate 1211 may be connected to the pivoting portion 122 .

[0063] 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 distributing its own weight; illustratively: the sewage collection device 100 also includes an elastic member (not shown in the figure), such as a torsion spring, which is connected between the water receiving tongue 120 and the sewage collection box 110. When the water receiving tongue body 123 is rotated by the force applied by the sewage and opens the sewage inlet 111, the elastic member undergoes elastic deformation. When the water receiving tongue body 123 is not pressed by an external force, it can be reset to a position covering the sewage inlet 111 under the elastic action of the elastic member; or the sewage collection device 100 also includes a driving member, such as a motor (not shown in the figure), which is assembled on the sewage collection box 110 and is transmission-connected to the water receiving tongue 120, and is used to drive the water receiving tongue 120 to rotate to open or cover the sewage inlet 111.

[0064] It should be understood that in other embodiments, the water receiving tongue 120 and the sewage collection box 110 may also be connected in a sliding manner, so that the sewage inlet 111 can be opened or covered by sliding of the water receiving tongue 120 .

[0065] It should be noted that the water receiving tongue 120 blocking the sewage inlet 111 means that the water receiving tongue 120 completely blocks the sewage inlet 111 without leaving any gaps. 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 with certain gaps.

[0066] Optionally, please continue to refer to Figure 2 and Figure 3 The sewage inlet 111 is arranged at the top of the sewage collection box 110, the top wall of the sewage collection box 110 is connected with an extension piece 112 extending into the interior of the sewage collection box 110, and the pivoting part 122 of the water receiving tongue 120 is rotatably connected with the extension piece 112; specifically, the sewage collection box 110 includes a box body 117 and a top plate 118 connected to the box body 117, the top plate 118 is provided with a sewage inlet 111, and the extension piece 112 is connected to the top plate 118 and is located at the sewage inlet 111 and extends into the inner cavity of the box body 117, and the pivoting part 122 is rotatably connected with one end of the extension piece 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 sewage inlet 111 shrinking inward, which is conducive to improving the problem of sewage dripping onto the water receiving tongue 120 and splashing when the sewage is discharged from the sewage inlet 111 into the sewage collection box 110.

[0067] Furthermore, when the water receiving tongue 120 is located at a position that blocks the sewage inlet 111, the second counterweight plate 1212 fits against the side of the extension piece 112 that faces the sewage inlet 111; in this way, when the counterweight portion 121 drives the water receiving tongue body 123 to rotate toward the position that blocks the sewage inlet 111, the extension piece 112 can be used to prevent the water receiving tongue 120 from excessively rotating.

[0068] Of course, in other embodiments, when the water receiving tongue 120 blocks the sewage inlet 111 , the water receiving tongue body 123 of the water receiving tongue 120 may also be flush with the sewage inlet 111 .

[0069] In order to improve the sedimentation of the silt, slag, etc. in the sewage in the sewage collection tank 110, and 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 also includes a stirring component 130, which is mounted on the sewage collection tank 110. Exemplarily, the stirring component 130 is mounted on the top of the sewage collection tank 110 (i.e., the top plate 118) and extends into the sewage collection tank 110; the stirring component 130 is used to stir the sewage collected in the sewage collection tank 110 to improve the problem of sediment, slag, etc. in the sewage being deposited at the bottom of the sewage collection tank 110.

[0070] Optionally, see Figure 4 The stirring assembly 130 includes a stirring motor 131, a stirring rod 132 and a stirring blade 133. The stirring motor 131 is assembled on the top of the sewage collection tank 110 (i.e., the top plate 118). The stirring rod 132 is drivingly connected to the output shaft of the stirring motor 131, and the stirring rod 132 extends into the sewage collection tank 110. The stirring blade 133 is connected to the stirring rod 132 and is located in the sewage collection tank 110. When the stirring motor 131 drives the stirring rod 132 to rotate, the stirring rod 132 drives the stirring blade 133 to rotate, so that the sewage collected in the sewage collection tank 110 is stirred by the stirring blade 133.

[0071] Of course, in other embodiments, the stirring assembly 130 can also be installed on the bottom or side wall of the sewage collection tank 110, that is, the stirring motor 131 can be installed on the bottom or side wall of the sewage collection tank 110, and the stirring rod 132 connected to the stirring motor 131 extends from the bottom or side wall of the sewage collection tank 110 into the sewage collection tank 110.

[0072] Optionally, the stirring blades 133 are distributed at one 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 collection tank 110 as possible to fully stir the sewage in the sewage collection tank 110 and improve the problem of sedimentation of silt, scum, etc.

[0073] Of course, in other embodiments, the stirring assembly 130 includes a plurality of stirring blades 133 , and the plurality of stirring blades 133 are all connected to the stirring rod 132 , and are sequentially spaced apart along the length extension direction of the stirring rod 132 .

[0074] In other embodiments, the sewage collection device 100 may not be equipped with the stirring assembly 130 .

[0075] In order to transport the sewage in the sewage collection tank 110 to the filtering device 200 for filtering; please refer to Figure 4 The sewage collection device 100 of this embodiment also includes a suction pipe 140, one end of the suction pipe 140 has a suction port 143, and the other end of the suction pipe 140 is connected to the filtering device 200. The suction pipe 140 is used to suck the sewage in the sewage collection tank 110 from the suction port 143 and transport it to the filtering device 200.

[0076] Optionally, the suction port 143 is disposed adjacent to the bottom of the sewage collection tank 110 , which is beneficial for sucking in solid matter such as silt, slag, etc. in the sewage, thereby reducing the deposition of silt, slag, etc. in the sewage collection tank 110 .

[0077] It should be noted that, since the sewage collection box 110 is provided with a stirring assembly 130 , mud, slag, etc. can be evenly mixed in the sewage, and it is helpful to improve the problem of mud, slag, etc. blocking the suction port 143 of the suction pipe 140 .

[0078] Of course, in other embodiments, the suction port 143 may also be disposed approximately in the middle of the sewage collection tank 110 .

[0079] In order to improve the problem that the sewage collection device 100 cannot successfully complete the corresponding collection work due to the blockage of the suction pipe 140; please continue to refer to Figure 4 In this embodiment, the sewage collection box 110 has two water storage chambers 113 inside, and the two water storage chambers 113 are connected through an overflow space 114; accordingly, the sewage collection device 100 includes two stirring components 130 and two suction pipes 140, and the water storage chambers 113, the stirring components 130 and the suction pipes 140 are arranged in a one-to-one correspondence, that is, the sewage in each water storage chamber 113 can be stirred by the corresponding stirring component 130, and the sewage in each water storage chamber 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 chamber 113. In this way, the sewage between the two water storage chambers 113 can flow through the overflow space 114. When the corresponding suction pipe 140 in one of the water storage chambers 113 fails (is blocked), the sewage in the water storage chamber 113 can flow into the other water storage chamber 113 through the overflow space 114, and be sucked out through the corresponding suction pipe 140 in the other water storage chamber 113, so as to improve the problem that the sewage in the sewage collection box 110 cannot be sucked out and overflows, thereby improving the operating stability of the sewage collection system 010; only when the suction pipes 140 corresponding to the two water storage chambers 113 are blocked or other faults occur, it is necessary to shut down and inspect and maintain.

[0080] It should be understood that in other embodiments, the number of water storage chambers 113 can also be one, three, four, etc.; in embodiments where the number of water storage chambers 113 is greater than two, the number of partitions 150, stirring assemblies 130 and suction pipes 140 also increases accordingly.

[0081] Optionally, the suction port 143 of the suction pipe 140 is configured to be distributed toward the axis of the water storage chamber 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 solid matter such as silt and dregs in the water storage chamber 113.

[0082] Please continue to refer to Figure 4 In this embodiment, a partition 150 is provided in the sewage collection tank 110, and the bottom end of the partition 150 is connected to the bottom of the sewage collection tank 110, so that the inner cavity of the sewage collection tank 110 is divided into two water storage chambers 113 by the partition 150, and the top end of the partition 150 is spaced apart from the top of the sewage collection tank 110. 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.

[0083] The connection methods of the partition 150 and the sewage collection tank 110 include but are not limited to integral molding, welding, and riveting.

[0084] Furthermore, the partition 150 includes two first guide surfaces 151 distributed opposite to each other, and the two first guide surfaces 151 correspond to the two water storage chambers 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, along the direction from the bottom of the sewage collection tank 110 to the top thereof, the distance between the two first guide surfaces 151 gradually decreases, so that the two first guide surfaces 151 form an inverted "V" shape. The first guide surface 151 can guide the solid matter such as mud, slag, etc. in the sewage to concentrate at the bottom of the water storage chamber 113 and near the axis of the water storage chamber 113, thereby improving the reliability of the suction pipe 140 in sucking out the mud, slag, etc., and effectively reducing the accumulation of mud, slag, etc. in the water storage chamber 113, especially reducing the problem of accumulation of solid matter such as mud, slag, etc. in the dead corners of the water storage chamber 113.

[0085] Optionally, the two first guide surfaces 151 are connected to each other at one end away from the bottom of the sewage collection tank 110, that is, one end of the first guide surface 151 extends to the bottom of the water storage chamber 113, and the other end of the first guide surface 151 is spaced apart from the top of the sewage collection tank 110 (that is, the top plate 118) to form an overflow space 114. Such an arrangement makes it easier for sewage to overflow between the two water storage chambers 113. Moreover, since the overflow space 114 is arranged at one end where the two first guide surfaces 151 are connected to each other, when the sewage in any water storage chamber 113 overflows into the other water storage chamber 113 through the overflow space 114, the solid matter such as mud, sand, and slag mixed in the sewage can be reliably concentrated to the bottom of the water storage chamber 113 under the blocking and guiding effect of the first guide surface 151, and is not easy to flow to the other water storage chamber 113 with the sewage, which is beneficial to clogging the suction pipe 140 corresponding to one of the water storage chambers 113. When the suction pipe 140 corresponding to the other water storage chamber 113 needs to be used to discharge the sewage, it is improved to improve the problem that there are too many solid matters such as mud, sand, and slag in the other water storage chamber 113, which easily clogs the suction pipe 140 corresponding to the other water storage chamber 113.

[0086] Of course, in other embodiments, the ends of the two first guide surfaces 151 away from the bottom of the sewage collection tank 110 may also be connected by a horizontal drainage surface, and the drainage surface is spaced apart from the top of the sewage collection tank 110 to form an overflow space 114.

[0087] In other embodiments, the partition 150 may include only one first guide surface 151 , and a side of the partition 150 facing away from the first guide surface 151 is a vertical plane.

[0088] Optionally, the first guiding surface 151 includes a first inclined surface 1511 and a second inclined surface 1512, one end of the second inclined surface 1512 extends to the bottom of the water storage chamber 113, and the other end of the second inclined surface 1512 is connected to the first inclined surface 1511, and one end of the first inclined surface 1511 away from the bottom of the water storage chamber 113 is spaced apart from the top of the sewage collection tank 110 to form an overflow space 114; wherein, the angle between the first inclined surface 1511 and the bottom of the water storage chamber 113 is smaller than the angle between the second inclined surface 1512 and the bottom of the water storage chamber 113. With such arrangement, the end of the second inclined surface 1512 away from the first inclined surface 1511 can be closer to the axis of the water storage chamber 113. Regardless of whether the solid matter such as mud, slag, etc. mixed in the sewage has been guided by the first inclined surface 1511 or not, it can be reliably moved to a position close to the axis of the water storage chamber 113 under the guidance of the second inclined surface 1512, so as to reliably discharge the solid matter from the water storage chamber 113 together with the sewage.

[0089] Furthermore, one end of the first inclined surface 1511 away from the overflow space 114 extends to the bottom of the water storage chamber 113, so that the stability of the partition 150 assembled in the sewage collection tank 110 can be improved. Of course, in other embodiments, the end of the first inclined surface 1511 away from the overflow space 114 can only extend to connect with the end of the second inclined surface 1512 away from the water storage chamber 113.

[0090] Optionally, the angle α between the first inclined surface 1511 and the bottom of the water storage chamber 113 is 110°-130° (for example: 110°, 115°, 120°, 125°, 130°, etc.); the angle β between the second inclined surface 1512 and the bottom of the water storage chamber 113 is 135°-150° (for example: 135°, 140°, 144°, 150°, etc.); the angle γ between the first inclined surface 1511 and the second inclined surface 1512 is 155-160° (for example: 155°, 156°, 158°, 160°, etc.). The ratio of the height of the partition 150 to the height of the overflow space 114 is: (2.67-4.50):1, for example: 2.67:1, 2.80:1, 3.05:1, 3.33:1, 3.81:1, 4.09:1, 4.50:1, etc.; illustratively: the height H2 of the partition 150 is 16-18 cm (for example: 16 cm, 16.3 cm, 16.5 cm, 17 cm, 17.29 cm, 17.4 cm, 18 cm, etc.), and the height H1 of the overflow space 114 is 4-6 cm (for example: 4 cm, 4.4 cm, 4.68 cm, 5 cm, 5.3 cm, 6 cm, etc.).

[0091] By optimizing the inclination angles of the first inclined surface 1511 and the second inclined surface 1512, as well as the heights of the partition 150 and the overflow space 114, on the one hand, the reliability of the sewage in the two water storage chambers 113 overflowing each other through the overflow space 114 can be ensured; on the other hand, when the suction pipe 140 corresponding to one of the water storage chambers 113 is blocked, causing the sewage in the water storage chamber 113 to overflow to the other water storage chamber 113, the first inclined surface 1511 can be used to reliably block the solid matter in the sewage in the water storage chamber 113 from flowing to the other water storage chamber 113 along with the sewage, and the second inclined surface 1512 can be used to reliably guide the solid matter in the sewage to flow to the bottom of the water storage chamber 113 where the suction pipe 140 is blocked, so as to improve the problem of a large increase in solid matter in the other water storage chamber 113, and effectively improve the problem of the suction pipe 140 corresponding to the other water storage chamber 113 being easily blocked, which is conducive to reducing the maintenance and cleaning frequency of the sewage collection device 100.

[0092] It should be understood that in other embodiments, the first guide surface 151 may only include the first inclined surface 1511 or only include the second inclined surface 1512; in an embodiment in which the first guide surface 151 only includes the first inclined surface 1511, one end of the first inclined surface 1511 extends to the bottom of the water storage chamber 113, and the other end is spaced apart from the top of the sewage collection tank 110 to form an overflow space 114; in an embodiment in which the first guide surface 151 only includes the second inclined surface 1512, one end of the second inclined surface 1512 extends to the bottom of the water storage chamber 113, and the other end is spaced apart from the top of the sewage collection tank 110 to form an overflow space 114.

[0093] Please refer to Figure 4 In this embodiment, the sewage collection tank 110 has two second guide surfaces 115, and the second guide surfaces 115 are the inner walls of the sewage collection tank 110; the two second guide surfaces 115 are spaced and distributed one by one with the two first guide surfaces 151, and there is a water storage chamber 113 between each group of relatively distributed first guide surfaces 151 and second guide surfaces 115; the spacing between the corresponding first guide surfaces 151 and second guide surfaces 115 gradually increases from the bottom to the top of the water storage chamber 113, so that the diameter of the water storage chamber 113 gradually increases from the bottom to the top; the second guide surfaces 115 can also guide the silt, slag, etc. in the sewage to concentrate in the middle of the water storage chamber 113, improve the reliability of the suction pipe 140 to suck out the silt, slag, etc., and effectively reduce the accumulation of silt, slag, etc. in the water storage chamber 113.

[0094] It should be understood that in other embodiments, the sewage collection tank 110 may not be provided with the second guide surface 115 , that is, the inner wall of the sewage collection tank 110 opposite to the first guide surface 151 may be provided as a vertical wall surface.

[0095] Optionally, see Figure 4 The second guide surface 115 includes a third inclined surface 1151 and a fourth inclined surface 1152. One end of the fourth inclined surface 1152 extends to the bottom of the water storage chamber 113, and the other end is connected to the third inclined surface 1151. The two ends of the third inclined surface 1151 extend to the bottom and top of the water storage chamber 113 respectively. The angle between the fourth inclined surface 1152 and the bottom of the water storage chamber 113 is greater than the angle between the third inclined surface 1151 and the bottom of the water storage chamber 113. In this way, the fourth inclined surface 1152 can be used to more reliably guide the solid matter in the sewage to concentrate in the direction close to the axis of the bottom of the water storage chamber 113.

[0096] The angle between the fourth slope 1152 and the bottom of the water storage chamber 113 is similar to the angle between the second slope 1512 and the bottom of the water storage chamber 113, the angle between the third slope 1151 and the bottom of the water storage chamber 113 is similar to the angle between the first slope 1511 and the bottom of the water storage chamber 113, and the angle between the fourth slope 1152 and the third slope 1151 is similar to the angle between the second slope 1512 and the first slope 1511, which will not be repeated here.

[0097] In other embodiments, the second guide surface 115 may only include the third slope 1151 or the fourth slope 1152 , wherein one end of the third slope 1151 or the fourth slope 1152 extends to the bottom of the water storage chamber 113 and the other end extends to the top of the water storage chamber 113 .

[0098] It should be noted that the guiding effect of the first guide surface 151 and the second guide surface 115 on the solid matter such as silt and dregs in the sewage is mainly when the stirring component 130 is not working, that is, the stirring component 130 does not stir the sewage in the water storage chamber 113. For example, when the sewage enters the water storage chamber 113 from the sewage inlet 111, the solid matter such as silt and dregs enters together with the sewage. In addition to moving under the action of the water flow, the solid matter such as silt and dregs can also Under the guidance of the first guide surface 151 and the second guide surface 115, the sewage moves toward the bottom of the water storage chamber 113 and in a direction close to the axis of the water storage chamber 113, thereby effectively reducing the accumulation of solid matter such as silt and scum in dead corners such as the bottom corner of the water storage chamber 113. When the sewage is stirred by the stirring assembly 130, the silt, scum and other solid matter can be more evenly mixed into the sewage, so that the silt, scum and other solid matter can be more reliably sucked out of the water storage chamber 113 together with the sewage.

[0099] Please continue to refer to Figure 4 Optionally, the portion of the suction pipe 140 extending into the water storage chamber 113 is distributed close to the second guide surface 115 .

[0100] Furthermore, the suction pipe 140 includes a first pipe 141 and a second pipe 142 connected at an angle, one end of the first pipe 141 away from the second pipe 142 is connected to the filter device 200, the first pipe 141 is connected to one end of the second pipe 142, and the second pipe 142 extends into the water storage chamber 113, and the end of the second pipe 142 away from the first pipe 141 is provided with a suction port 143; the second pipe 142 is distributed close to the second guide surface 115. Such a configuration can improve the part of the suction pipe 140 extending into the water storage chamber 113 to interfere with the stirring assembly 130 stirring the sewage, thereby ensuring that mud, sand, scum, etc. can be more evenly mixed into the sewage.

[0101] 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 in detail.

[0102] Of course, in other embodiments, the portion of the suction pipe 140 extending into the water storage chamber 113 may also be configured to be distributed close to the first guide surface 151 .

[0103] Please refer to Figure 5 Optionally, the sewage collection device 100 further includes a cover plate 160, and a first inspection port 116 is provided on the top of the sewage collection tank 110 (i.e., the top plate 118), and the cover plate 160 is detachably or movably connected to the sewage collection tank 110, and is used to open or close the first inspection port 116. In this way, it is convenient to use the cover plate 160 to open the first inspection port 116, and to inspect the stirring assembly 130 and the part of the suction pipe 140 extending into the water storage chamber 113.

[0104] The connection methods of the cover plate 160 and the sewage collection box 110 include but are not limited to snap connection, rotation connection, sliding connection, and connection with fasteners such as bolts.

[0105] Of course, in other embodiments, the sewage collection tank 110 may not be provided with the first inspection port 116 .

[0106] Optionally, see Figure 2 In some embodiments, the sewage collection system 010 further includes a cleaning device 161, which includes a water storage component 162 and a water inlet pipe 163. The water storage component 162 is connected to the water storage chamber 113 through the water inlet pipe 163, so that the water stored in the water storage component 162 is transported to the water storage chamber 113 for cleaning by using the water inlet pipe 163. The water storage component 162 includes but is not limited to a water storage tank and a water storage ditch.

[0107] Optionally, an on-off valve (not shown) is also provided on the water inlet pipe 163 to control the on-off of the water inlet pipe 163 by means of the on-off valve, so that the water inlet pipe 163 is opened to deliver flushing water to the water storage chamber 113 only when the water storage chamber 113 needs to be cleaned.

[0108] Please refer to Figure 6 and Figure 7The filtering device 200 of this embodiment includes a filtering tank 210 and a filtering net 220. The filtering tank 210 has a filtering chamber 211. One end of the suction pipe 140 away from the suction port 143 is connected to the filtering tank 210, and connects the water storage chamber 113 and the filtering chamber 211, so that the sewage sucked from the water storage chamber 113 by the suction pipe 140 can enter the filtering chamber 211; the filtering net 220 is arranged in the filtering chamber 211, and is used to filter the sewage entering the filtering chamber 211, so as to prevent large particles of sediment, plastic and other debris from flowing to the downstream sewage tank 300, thereby improving the problem of downstream pipeline blockage.

[0109] Furthermore, the filter screen 220 is arranged vertically to divide the filter chamber 211 into a filter residue chamber 212 and a filtrate chamber 213 distributed laterally; wherein, the suction pipe 140 is connected to the filter residue chamber 212, and the filtrate chamber 213 is connected to the sewage tank 300. After the sewage entering the filter residue chamber 212 is filtered by the filter screen 220, the filter residue remains in the filter residue chamber 212, and the filtrate enters the filtrate chamber 213 and flows into the sewage tank 300 through the filter liquid chamber 213.

[0110] Optionally, the filter screen 220 extends in the vertical direction so that the filter residue chamber 212 and the liquid passage chamber are distributed left and right in the horizontal direction. Of course, in other embodiments, the filter screen 220 can also form a certain angle with the vertical direction, for example, the extension direction of the filter screen 220 can differ from the vertical direction by 1°, 3°, etc., which is not specifically limited here.

[0111] The connection methods of the filter screen 220 and the inner wall of the filter tank 210 include but are not limited to integral molding, plug-in, and connection with fasteners such as bolts.

[0112] Please refer to Figure 6 , a filter residue outlet 214 is provided at the bottom of the filter tank 210 of the present embodiment, specifically, the filter residue outlet 214 is provided at the bottom of the filter residue cavity 212 and is communicated with the filter residue cavity 212; the filter device 200 further comprises an opening and closing assembly (not shown in the figure), which is provided at the filter tank 210 and is used to open or close the filter residue outlet 214; when the opening and closing assembly closes the filter residue outlet 214, the filter net 220 provided in the filter tank 210 can be used to reliably filter the sewage entering the filter residue cavity 212, so that the filter residue accumulates at the bottom of the filter residue cavity 212; when the filter device 200 is used to complete the filtration of sewage, the opening and closing assembly can be used to open the filter residue outlet 214, and then the filter residue accumulated at the bottom of the filter residue cavity 212 can be dropped out of the filter residue cavity 212 to achieve the cleaning of the filter residue.

[0113] The structure of the opening and closing component can be set as needed. For example: the opening and closing component includes an opening and closing plate and an opening and closing motor. The opening and closing plate is slidably connected to the filter tank 210, and the opening and closing motor is transmission-connected to the opening and closing plate, for driving the opening and closing plate to slide relative to the filter tank 210 to open or close the filter residue outlet 214; in this way, when filtering is performed using the filter net 220, the opening and closing motor can be used to drive the opening and closing plate to slide to close the filter residue outlet 214 to ensure that the sewage can reliably flow from the filter residue cavity 212 through the filter net 220 into the filtrate cavity 213 to complete the filtration without leaking from the filter residue outlet 214; when the filter residue needs to be poured out, the opening and closing motor can be used to drive the opening and closing plate to slide to open the filter residue outlet 214 to allow the filter residue to fall out of the filter residue outlet 214.

[0114] Of course, in other embodiments, the opening and closing plate may also be configured to be rotatably connected to the filter tank 210 .

[0115] Optionally, in some embodiments, the opening and closing motor is configured to control the opening and closing plate to open the filter residue outlet 214 at a set time. For example, the opening and closing motor is configured to control the opening and closing plate to open the filter residue outlet 214 at 7 pm every day. In this way, the filter residue in the filter tank 210 can be cleaned in time every day.

[0116] Alternatively, in other embodiments, the opening and closing motor is configured to control the opening and closing plate to open the filter residue outlet 214 at set time intervals. For example, the opening and closing motor is configured to control the opening and closing plate to open the filter residue outlet 214 at set time intervals.

[0117] Alternatively, in some other embodiments, the filtering device 200 also includes a weighing assembly (not shown), which is disposed at the bottom of the opening and closing plate or the filter residue chamber 212, and is used to weigh the weight of the filter residue accumulated at the bottom of the filter residue chamber 212; the opening and closing motor is configured to control the opening and closing plate to open the filter residue outlet 214 when the weighing assembly detects that the weight of the filter residue reaches a preset value, so as to clean the filter residue in the filter residue chamber 212 in time.

[0118] In order to allow the sewage entering the filtrate chamber 213 to smoothly enter the sewage tank 300; please refer to Figure 6 In this embodiment, the filter tank 210 is further provided with a water outlet pipe 230 communicating with the filtrate chamber 213 , and the connection between the water outlet pipe 230 and the filter tank 210 is close to the bottom of the filtrate chamber 213 .

[0119] Optionally, in the vertical direction, the filter tank 210 is arranged above the sewage tank 300, that is, the filter tank 210 is arranged at a higher height than the sewage tank 300; and one end of the outlet pipe 230 away from the filter tank 210 is connected to the top of the sewage tank 300. In this way, it is helpful to ensure that the sewage in the filtrate cavity 213 flows into the sewage tank 300 more reliably.

[0120] Please refer to Figure 8 In this embodiment, the filter device 200 further includes a conveying assembly 240, which is disposed below the filter residue outlet 214 and is used to receive the filter residue dropped from the filter residue outlet 214 and to convey the received filter residue. This arrangement can improve the problem of the filter residue dropped from the filter residue outlet 214 accumulating at the filter residue outlet 214, and can clean the filter residue without manual intervention, thereby realizing an automated filter residue cleaning process.

[0121] Garbage disposal stations (such as garbage transfer stations) are also provided with a hopper 510, a compressor 520 and a garbage bin (not shown in the figure). The hopper 510 is installed at the feed port of the compressor 520, and the hopper 510 is used to receive the garbage so that the garbage enters the compressor 520 under the guidance of the hopper 510; the compressor 520 is used to compress the garbage, and the garbage bin is used to receive the garbage compressed by the compressor 520.
