Description

Technical Field

[0001] The invention relates to the technical field of sewer pipes, in particular to sewage treatment equipment suitable for urban sewers. Background Art

[0002] Sewers are a type of urban public facility, which refers to pipes used by buildings to discharge sewage and rainwater, and also refers to underground passages used by cities, factories or villages to discharge sewage and rainwater. When municipal roads are flooded, sewers play an important role in drainage; however, in extreme weather such as floods, water flows with a large amount of debris when they flow into the sewer wells. Because the impurities in the sewage in urban sewers are relatively complex, when there are large debris in the sewage, the blockage of the pipeline is more difficult to clean and remove by water pressure and other means than the blockage caused by the accumulation of small impurities on the pipeline, and may even cause the pipeline to become blocked. The most common and difficult to clean large debris are generally plastic film products, such as plastic bags. Because plastic film products are light in weight and easily washed away, over time, municipal road sewers are prone to blockage, making it difficult to discharge sewage.

[0003] When dealing with plastic film products in sewers, in order to reduce the amount of plastic film products brought into the sewer pipes, a filter is generally installed at the sewer manhole for filtration. However, excessive accumulation of plastic bags can easily cause the mesh of the filter to be covered and affect normal drainage. However, if there is no filter, under the impact of water flow, the plastic bags flow at a fast speed, making it difficult to select and separate the plastic bags from the sewage, resulting in a large amount of plastic products flowing into the underground passage, causing blockage of the underground pipes. During the unblocking process of the blocked sewer, the pipe unblocking robot usually extracts the plastic bags and then crushes them immediately. This treatment method is not only likely to cause the crushed plastic products to remain in the sewer and mix with the sewage again, but also some plastic bags are prone to carry accumulated water, resulting in poor crushing effect, which also reduces the debris handling effect and affects the drainage efficiency of the pipeline.

[0038] Reference Figure 1 to Figure 8, is an embodiment of the present invention, which provides a sewage treatment device suitable for urban sewers, comprising a drain port 100 placed on the ground, a deflectable drain plate 101 provided on the drain port 100, and water and impurities can flow in from the gap between the drain plate 101 and the drain port 100;

[0039] The sewer port 100 is placed at the upper end of the sewer pipe 200, and the sewer pipe 200 is placed underground. A plurality of separation columns 600 are spirally distributed from top to bottom inside the sewer pipe 200. The separation columns 600 are movably connected to the inner wall of the deflection groove 201 on the sewer pipe 200. The separation columns 600 retain the plastic bag garbage falling from the sewer port 100 through the convex nails 604.

[0040] A receiving bucket 400 is provided in the middle of the sewer pipe 200. The receiving bucket 400 receives sewage. As the amount of sewage increases, the receiving bucket 400 moves downward. The side of the receiving bucket 400 is connected to the first pull rope 102 and the second pull rope 501 through a movable joint 401. The other ends of the first pull rope 102 and the second pull rope 501 are respectively connected to the water discharge plate 101 and the spiral bracket 500. The water discharge plate 101 deflects to block the entrance of the water discharge port 100. The spiral bracket 500 moves upward, and the rack 502 on the spiral bracket 500 drives the separation column 600 to rotate.

[0041] During the rotation of the separation column 600, the rotating head 605 of the movable end of the separation column 600 passes through the cylindrical protrusion 202 on the bottom surface of the deflection groove 201 on the sewer pipe 200, and the central axis 606 in the separation column 600 rotates to a preset angle. At the same time, the extrusion head 608 on the central axis 606 squeezes the separation head 607, and the separation head 607 separates the plastic bag garbage on the protruding nail 604.

[0042] The upper end of the water outlet 100 is provided with a port frame 104, and the port frame 104 is provided with a water inlet 105. The inner wall of the water inlet 105 is movably connected to the water outlet plate 101. The side of the water outlet 100 is provided with a second roller 106. The water outlet plate 101 is usually placed in the water inlet 105 in an inclined state.

[0043] One end of the first pull rope 102 is connected to the inner end of the water discharge plate 101 , and the other end is connected to the movable joint 401 after passing around the first roller 103 at the inner edge of the water inlet 105 .

[0044] Preferably, the water discharge plate 101 is fan-shaped, the shape of the water discharge plate 101 matches the shape of the water inlet 105, the side of the water discharge plate 101 is movably connected to the water inlet 105, and a torsion spring is provided at the connection. When the torsion spring is not subjected to force, the water discharge plate 101 is placed in the water inlet 105 in an inclined state.

[0045] Four water discharge plates 101 are arranged in a circular array on the port frame 104. The first pull ropes 102 connected to two adjacent water discharge plates 101 are connected to a movable joint 401 on the receiving bucket 400, and the first pull ropes 102 on the other two adjacent water discharge plates 101 are connected to another movable joint 401. Every two first pull ropes 102 are connected to a movable joint 401. The first pull rope 102 is placed on one side of the receiving bucket 400 to ensure that the receiving bucket 400 can move vertically downward following gravity when receiving sewage. When the receiving bucket 400 reaches the maximum value of receiving sewage, the receiving bucket 400 can be flipped smoothly.

[0046] A plurality of deflection grooves 201 are provided on the sewer pipe 200, and a separation column 600 is connected to the upper end of each deflection groove 201. A cylindrical protrusion 202 is provided on the bottom surface of each deflection groove 201. A collecting channel 300 is provided on the outer side of the sewer pipe 200. The collecting channel 300 is placed at the lower end of the deflection groove 201, and the collecting channel 300 is spirally fixed on the outer side of the sewer pipe 200; a spiral bracket 500 is provided on the outer side of the upper end of the deflection groove 201.

[0047] The side of the receiving bucket 400 is movably connected to the movable joint 401, and the movable joint 401 is simultaneously connected to the first pull rope 102 and the second pull rope 501. The two movable joints 401 are placed in the middle of the outer side of the receiving bucket 400, and a counterweight is set on the bottom of the receiving bucket 400. When the water in the receiving bucket 400 reaches a preset amount, the receiving bucket 400 can be flipped over.

[0048] The spiral bracket 500 is placed in a spiral shape on the outside of the sewer pipe 200. A plurality of racks 502 are arranged on the spiral bracket 500. Each rack 502 is meshed with a driving gear 602 on a corresponding separation column 600. The inner wall of the spiral bracket 500 is contacted and limited by a limiting groove 505 on the outer wall of the sewer pipe 200 through a movable block 504. One end of the second pull rope 501 is connected to the spiral bracket 500, and the other end of the second pull rope 501 is connected to the movable joint 401 after passing around the second roller 106; a plurality of connecting brackets 503 are arranged on the spiral bracket 500, and the connecting bracket 503 is used to connect two points of the spiral bracket 500 in the vertical direction.

[0049] Preferably, the connecting bracket 503 is used to fix the spiral bracket 500 into a whole, so that the spiral bracket 500 is more stable.

[0050] Preferably, the rack 502 moves vertically along with the spiral bracket 500 , and the rack 502 is vertically fixed on the spiral bracket 500 .

[0051] The spiral bracket 500 moves up along with the receiving barrel 400 through the second pull rope 501, and the rack 502 moves up at the same time. The rack 502 drives the driving gear 602 to rotate, thereby driving the separation column 600 to rotate. The separation column 600 is horizontal when it is not rotated, and the rotation angle is greater than 90°. After the rotating head 605 passes through the cylindrical protrusion 202, the central axis 606 rotates, the separation head 607 is squeezed out, and the convex nail 604 loses its restraint on the plastic product. The plastic product falls on the collection channel 300 and then flows downward with the sewage.

[0052] The separation column 600 is provided with convex studs 604, which are distributed in a ring shape on the outer side of the separation column 600. A plurality of annularly distributed convex studs 604 form a group, and each group of convex studs 604 is distributed in a linear array on the separation column 600. A column head 601 is provided at one end of the separation column 600, and a driving gear 602 is provided on one side of the column head 601. The column head 601 and the driving gear 602 are movably connected to the upper end of the deflection slot 201 through a rotating shaft 603.

[0053] The separation column 600 is hollow inside and has a central shaft 606 therein. An extrusion head 608 is provided on the central shaft 606. The extrusion head 608 is used to extrude the separation head 607. The distribution of the separation head 607 and the extrusion head 608 is consistent with the distribution of the convex nail 604. The separation head 607 is placed on one side of the convex nail 604.

[0054] The inner end of the detaching head 607 and the extrusion head 608 are triangular-shaped. The extrusion head 608 will squeeze the detaching head 607 during the rotation of the central axis 606, and the detaching head 607 will expand, and the outer end of the detaching head 607 will exceed the upper end of the protruding nail 604;

[0055] The side of the separation head 607 is connected to the inner wall of the separation column 600 through a spring 609. The side of the separation head 607 is provided with an active slot 610. The active slot 610 is provided with a clamping strip 611. The clamping strip 611 is placed on the inner wall of the movable opening between the separation head 607 and the separation column 600. The spring 609 completes the reset of the separation head 607 after the separation head 607 loses its extrusion.

[0056] One end of the central shaft 606 is movably connected to the inner end of the column head 601 , and the other end of the central shaft 606 is provided with a rotating head 605 , on which convex heads distributed in a ring array are provided.

[0057] The cylindrical protrusion 202 is fixed to the bottom surface of the deflection groove 201 , and after the protrusion on the rotating head 605 passes through the cylindrical protrusion 202 , the central axis 606 will rotate by a preset angle.

[0058] The water discharge plate 101 is semi-enclosed, and an opening is provided at the inner end of the water discharge plate 101 . The water discharge plate 101 guides the water flow into the receiving bucket 400 .

[0059] like Figure 8 As shown, the movable joint 401 is at the center of the outer side of the receiving barrel 400, but the center of the movable joint 401 is slightly biased to one side of the center point of the outer side of the receiving barrel 400. When the receiving barrel 400 receives rainwater, the receiving barrel 400 still keeps moving downward. When the water in the receiving barrel 400 reaches a certain amount, the center of gravity of the barrel shifts, and the receiving barrel 400 flips over. When all the water in the barrel flows out, the counterweight at the bottom of the barrel allows the barrel to reset.

[0060] When in use, sewage carries plastic products into the device, and the plastic products will be hung on the separation column 600 during the falling process. At the same time, the receiving bucket 400 will continuously receive sewage. When the sewage in the receiving bucket 400 gradually increases, the receiving bucket 400 moves downward, and the receiving bucket 400 gradually triggers the water discharge plate 101 and the separation column 600 through the first pull rope 102 and the second pull rope 501. Finally, the water discharge plate 101 is closed, the separation column 600 completes the deflection, and the plastic products on the separation column 600 will fall off onto the collecting channel 300, and then flow downward along the collecting channel 300. At the same time, the receiving bucket 400 reaches the maximum receiving capacity, the receiving bucket 400 completes the flipping, and then resets. The torsion spring of the water discharge plate 101 drives the water discharge plate 101 to restore the inclined state, and the pipeline begins to fill with water. The receiving bucket 400 moves up and resets in the opposite direction through the first pull rope 102, and then repeats the above content again; the entire device is repeatedly closed and opened, and plastic products are collected each time.

[0061] In summary, the device sets a spirally distributed separation column 600 inside the sewer pipe, and uses the separation column 600 to separate the plastic products in the sewage. The spirally distributed separation column 600 does not affect other impurities entering the interior of the pipe along the separation column 600. At the same time, a receiving barrel 400 is set inside the device, and the receiving barrel 400 will receive sewage. When the sewage becomes more, the receiving barrel 400 will trigger the water discharge plate 101 and the spiral bracket 500, and then close the water discharge plate 101 to prevent the sewage from continuing to enter; at the same time, the separation column 600 is rotated, and then the plastic products on the separation column 600 are detached. Finally, the plastic garbage will enter the collection area of ​​​​the plastic products along the collection channel 300 along with the sewage; after that, the sewage in the receiving barrel 400 overflows, the receiving barrel 400 flips over to dump the sewage, the device is reset, and drainage is performed again.
