[0002] Water supply and drainage engineering refers to the water supply and drainage system designed and constructed to meet the needs of human life and production. It covers many aspects such as the sustainable use of water resources and water quality management. Water supply and drainage engineering requires the design of sewage treatment equipment. Traditional sewage treatment equipment mostly uses rigid pipes and filtration systems.

[0003] In similar fields, limited installation space often requires a large amount of space to accommodate pipe layout and fluid guidance, especially in areas with small building spaces or complex terrain. This results in poor installation adaptability, high installation complexity, and an inability to flexibly respond to changes in sewage flow. Furthermore, there are problems with sewage distribution in bends, leading to uneven sewage flow, failure to fully utilize filtration performance, and impact on sewage treatment efficiency. Summary of the Invention

Detailed Implementation

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] Please see Figures 1-16 The present invention provides a technical solution: a sewage treatment equipment for water supply and drainage engineering, comprising: a filter pipe 1, wherein the filter pipe 1 is equipped with filter packing, wherein the filter packing can be biological packing or microporous filter packing, and the filter pipe 1 is provided with corresponding pipes according to the type of packing, such as aeration pipes or liquid addition and backwashing pipes.

[0064] The flexible bend section 2 is connected to the inlet side of the filter pipe 1 and the flexible bend section 2 is connected to the sewage outlet side of the water supply and drainage system. The flexible bend section 2 adapts to the inclined assembly angle of the sewage outlet side.

[0065] Flexible corrugated pipe 5, multiple flexible corrugated pipes 5 are arranged around the flexible bend section 2. The multiple flexible corrugated pipes 5 guide the sewage to the filter pipe 1 to shorten the sewage distribution space. The flexible corrugated pipes 5 flexibly unfold with the flexible bend section 2 to fully guide the sewage. Each of the two open sides of the multiple flexible corrugated pipes 5 is provided with a fixing ring 4, which is installed in the flexible bend section 2.

[0066] The support mechanism 8 includes a plurality of support rings 801 disposed within the flexible bend section 2. The plurality of support rings 801 are configured to stably support the flexible corrugated pipe 5 as it unfolds.

[0067] Specifically: Through the design of the flexible corrugated pipe 5 and the flexible bend section 2, it is possible to flexibly unfold in the pipe bend area, which is conducive to adapting to the installation area of ​​different water supply and drainage projects. Furthermore, the flexible corrugated pipe 5 can guide the sewage to be distributed on the inlet side of the bend area, thereby reducing the liquid distribution space in the vertical area of ​​the filter pipe 1, improving the integration of the device, and helping to ensure the filtration flux under the bend assembly and improve the filtration efficiency.

[0068] The flexible corrugated pipe 5 can be made of elastic plastic parts or elastic metal corrugated pipe parts with corrosion-resistant coatings to ensure its long-term stability in harsh environments.

[0069] Furthermore, the flexible bend 2 can be partially unfolded and laterally offset around the axis, which is beneficial to adapting to various installation situations, and the flexible corrugated pipe 5, which moves and unfolds along with the pipe, can maintain the sewage guidance and distribution effect.

[0070] In one embodiment, the flexible bend can be bent to 90° to guide the pipes on both sides, and the inner side of the flexible bend 2 is supported by the support mechanism 8. The built-in support mechanism 8 can shorten the arrangement gap on the inlet side and improve the installation adaptability.

[0071] Furthermore, in another embodiment, the flexible bend section 2 can be installed at an inclined angle through the two side fixing rings 4, and the inclined flexible bend section 2 can be supported by the support mechanism 8 in sequence.

[0072] Please see Figures 5-8 The supporting institution 8 also includes:

[0073] Ball bearing 807, multiple ball bearings 807 are connected around the axis of support ring 801 and connected to the outside of support ring 801, and a steering ball 808 is rotatably connected inside the ball bearing 807;

[0074] A limiting groove 809, multiple limiting grooves 809 are connected around the bottom side of the flexible bellows 5 at the corresponding position. The limiting groove 809 is a flexible cavity and is configured to unfold with the flexible bellows 5. The side of the limiting groove 809 near the supporting ring 801 has a sliding cavity. Multiple guide blocks 810 are arrayed equidistantly in the sliding cavity. The guide blocks 810 are connected to the top of the steering ball 808 outside the supporting ring 801 at the corresponding position. The steering ball 808 rotates in the ball bearing 807 and unfolds with the supporting ring 801.

[0075] To prevent the flexible bend section 2 from vibrating due to the flexible structure after opening, thus affecting the sewage output and ensuring the overall stability of the flexible bend section 2 after unfolding, specifically: through the designed support mechanism 8, multiple flexible bend sections 2 can be simultaneously pulled to the flexible corrugated pipe 5 when unfolded. The unfolding of the flexible corrugated pipe 5 can pull the limiting groove 809 to unfold. After the flexible limiting groove 809 unfolds, it can pull the steering ball 808 through the guide block 810 to pull the corresponding supporting ring 801 to unfold. Thus, the rotation of the steering ball 808 in the ball bearing 807 can adapt to the unfolding of the supporting ring 801. The equidistantly unfolded supporting ring 801 can support multiple flexible corrugated pipes 5 on the outer periphery, improving the support stability of the flexible corrugated pipe 5 and the flexible bend section 2 after unfolding.

[0076] Tension ribs 803, multiple tension ribs 803 are inserted into the grooves that are opened around the side of the support ring 801. Fixing blocks 802 are sleeved on both ends of the tension ribs 803. The fixing blocks 802 are connected to the bottom of the flexible corrugated pipe 5. The tension of the tension ribs 803 stabilizes the multiple support rings 801.

[0077] The first spring 804, the two first springs 804 are located at both ends of the tension rib 803, and both ends of the tension rib 803 are connected to the blocking block 805. The two ends of the first spring 804 are respectively connected to the corresponding positions of the fixing block 802 and the blocking block 805.

[0078] The universal ball sleeve 806 is rotatably connected to the groove on the side of the support ring 801. The groove has a ball groove that matches the universal ball sleeve 806. A through tube is connected inside the universal ball sleeve 806. The through tube is sleeved outside the tension rib 803. The rotation of the universal ball sleeve 806 in the groove reduces the rotational interference between the tension rib 803 and the support ring 801.

[0079] Specifically: Through the designed support mechanism 8, when multiple support rings 801 are unfolded, they can contact the fixed block 802 to unfold the tension rib 803. When the tension rib 803 is unfolded, it can compress the external first spring 804. Thus, the support rings 801 can be supported and buffered by the multiple circumferentially arranged first springs 804 and tension ribs 803, which is beneficial to improving the support stability between multiple sets of support rings 801.

[0080] Meanwhile, when adapting to different installation angles, the support ring 801 can adapt to the arc-shaped unfolding of the tension rib 803 by rotating the inner universal ball sleeve 806 within the groove, avoiding contact interference between the tension rib 803 and the groove that would affect the support stability. Furthermore, the arrangement direction of multiple support rings 801 can be adjusted by inserting them through the tension rib 803.

[0081] Please see Figure 15In one example, when multiple support rings 801 are connected to the flexible bend section 2, the portions of the multiple support rings 801 located at the bottom of the bend are brought together, and the unfolded portions located at the top of the bend are fully unfolded to adapt to the unfolding angle of the flexible bend section 2, which is shown as the dashed line portion in the figure.

[0082] Please see Figure 16 In another embodiment, the inclined flexible bend 2 allows multiple support rings 801 to be arranged at an incline for guidance and support, as shown by the dashed line in the figure.

[0083] Please see Figure 9 and Figure 10 It also includes: a guiding mechanism 9, which includes a fixed plate 901 located on the inner wall of the flexible corrugated pipe 5 near the filter pipe 1. A plurality of guide plates 904 are provided on one side of the fixed plate 901 to guide the flow of sewage.

[0084] It also includes: a base 903, multiple bases 903 are arranged in an arc-shaped angular array along the fixed plate 901, and a guide plate 904 is rotatably connected to the base 903;

[0085] A drive sprocket 902, multiple drive sprockets 902 are connected to one side of the base 903 via a rod, and the multiple drive sprockets 902 are connected to each other via chain drive;

[0086] The force-bearing ring 905 is connected to the top of the guide plate 904 via a shaft passing through the base 903. The guide plate 904 drives the shaft and the force-bearing ring 905 to rotate. The force-bearing ring 905 is configured to be elastically limited to adjust the guide stroke of the guide plate 904.

[0087] Two springs 906 are connected to the top of the base 903 in opposite positions. The arc-shaped surface of the spring 906 contacts the protrusion 907 connected to the outside of the force ring 905. The springs 906 abut against the protrusion 907 to buffer and absorb energy from the guide plate 904.

[0088] A shielding plate 10, multiple shielding plates 10 are connected between adjacent stabilizing frames 703, and the gaps are closed by the shielding plates 10;

[0089] Specifically: Through the designed guiding mechanism 9, when sewage is sent into the opening on one side of the flexible bend section 2 by the external pumping equipment, the sewage can be guided through multiple flexible corrugated pipes 5. After flowing in the flexible corrugated pipes 5, the sewage can be evenly distributed to the top of the sewage treatment biological packing in the filter pipe 1, which is conducive to the biological treatment of sewage through the sewage treatment biological packing. When the sewage flows to the end of the flexible corrugated pipe 5, multiple guide plates 904 can partially guide the flow direction of the sewage.

[0090] Furthermore, when the guide plate 904 is impacted by sewage, it can rotate and deflect around the transmission sprocket 902 via the base 903, thereby fully guiding the water flow. When the transmission sprocket 902 rotates, it can synchronously drive multiple bases 903 on the periphery to deflect in the same direction via the chain. The multiple synchronously deflected guide plates 904 can improve the guiding and treatment effect of sewage and further improve the uniformity of contact between sewage and biological packing.

[0091] Furthermore, when the guide plate 904 is subjected to lateral impact, the guide plate 904 can drive the protrusion 907 to squeeze the spring sheet 906 through the force ring 905. The spring sheet 906 can use its own elasticity to buffer the guide plate 904, which is beneficial to improve the buffering stability of the guide plate 904. The buffering fluctuation of the guide plate 904 improves the flow effect of sewage.

[0092] Please see Figure 11 and Figure 12 The adjustment mechanism 7 includes:

[0093] The rotating ring 701 is rotatably connected to one side of the fixed ring 4. Multiple connectors 702 are connected around one side of the rotating ring 701. The connectors 702 extend through the grooves opened at corresponding positions on the outer periphery of the fixed ring 4 to the inner side of the fixed ring 4.

[0094] The stabilizing frame 703 is connected to one end of the flexible corrugated tube 5 at the corresponding position. The outer side of the stabilizing frame 703 is connected to one end of the connector 702 that extends to the inner side of the fixing ring 4. The swivel ring 701 is rotated to pull the stabilizing frame 703 to pull the flexible corrugated tube 5 and adjust the guide spiral angle.

[0095] The guide wheel 6 has a drive unit installed on its rear side. The drive unit is connected to one side of the adjacent support ring 801 via a mounting component. The guide wheel guides the sewage to flow towards the peripheral flexible corrugated pipe 5. The guide wheel 6 is designed so that the drive unit can control the rotation of the guide wheel 6.

[0096] In this embodiment, the driving unit is a drive motor;

[0097] Furthermore, through the designed directional mechanism 7, in order to improve the flowability of sewage, after the flexible bend section 2 is installed, the position of the rotating ring 701 outside the fixed ring 4 can be adjusted. The rotation of the rotating ring 701 can pull the connecting piece 702 to pull the stabilizing frame 703. The stabilizing frame 703 is pulled and can drive the end of the flexible corrugated pipe 5 to rotate circumferentially. Through the rotation of the flexible corrugated pipe 5 around the axis, the flexible corrugated pipe 5 located at the top of the bend can be twisted. Through the twisted flexible corrugated pipe 5, the sewage located at the top can overcome the upward water flow pressure and accelerate and stay in the middle of the twisted flexible corrugated pipe 5, thereby improving the flow rate control effect of the circumferential sewage distribution of the flexible corrugated pipe 5.

[0098] Among them, the flexible corrugated pipe 5 is a square corrugated pipe or a round corrugated pipe to ensure the guiding effect;

[0099] Buffer mechanism 3 includes:

[0100] Damping resistor 303, both ends of which are rotatably connected to first buffer plate 301 via rotating pair 302, and the bottom of first buffer plate 301 is connected to the outside of fixed ring 4;

[0101] Support member 306, both ends of support member 306 are bolted to universal joints 305, and the ends of the universal joints 305 on both sides that are far apart are connected to second buffer plates 304. The second buffer plates 304 are connected to the other side of the fixing ring 4. The flexible bend section 2 can be unfolded by rotating support member 306 around universal joint 305.

[0102] Specifically: Through the designed buffer mechanism 3, when the assembly method of the flexible bend section 2 needs to be adjusted, the support 306 with the corresponding installation method can be replaced. After the support 306 is connected to the corresponding universal joint 305, the unfolded shape of the flexible bend section 2 on one side can be adjusted. After the flexible bend section 2 on one side is adjusted, the damper 303 on the other side can be unfolded to adapt to the control of the unfolding angle through the rotating pair 302.

[0103] Furthermore, the adjustment to the assembly method of the flexible bend section 2 is more specifically as follows: when the bend section assembly is required, a prefabricated arc-shaped support 306 should be selected. After the arc-shaped support 306 is connected to the universal joints 305 on both sides, the flexible bend section 2 on that side can be unfolded in an arc. The designed universal joints 305 can fully adapt to the unfolding angle of the flexible bend section 2, thereby improving the assembly stability.

[0104] In another embodiment, if tilted assembly is required, the tilt offset installation angle can be adjusted by replacing the longitudinal support member 306 of the corresponding length and adjusting the support stroke through the support member 306.

[0105] The embodiments disclosed in this invention are merely illustrative of the installation. Other installation methods may include combinations of multiple continuous bends and should not be considered as limitations on the installation method. Furthermore, the support member 306 can be replaced according to assembly needs, including but not limited to adjustments to the unfolding angle, unfolding method, or tilt angle.
