Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a suspended solids filtration device for municipal wastewater treatment. Background Technology

[0002] Suspended solids filtration devices in municipal wastewater treatment are mainly used to remove suspended solids from wastewater to ensure that the discharged water meets the standards and reduce pollution.

[0003] If the filter box cannot be quickly installed and removed, the time required for equipment maintenance and cleaning will increase significantly, requiring the entire unit to be shut down for extended periods of maintenance. This results in prolonged downtime of the wastewater treatment system, reducing the overall system's continuous operating efficiency.

[0004] Secondly, without turbulence treatment, suspended solids in wastewater will settle unevenly within the device. Larger particles may settle prematurely in certain areas of the system, causing localized blockages in the filter media or pipes. Without centrifugal separation, conventional sedimentation or filtration may not be able to effectively separate suspended solids with high specific gravity and large particle size (such as silt, mineral particles, etc.).

[0005] Finally, without an influent control function, the system cannot adjust the influent and effluent conditions according to changes in the influent flow rate, thus failing to effectively control suspended solids in the wastewater. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5 A municipal wastewater treatment suspended solids filtration device includes a main body 1, a quick-assembly mechanism, a turbulence mechanism, and a water flow control mechanism. The quick-assembly mechanism includes a filter box 2, a spring 3, a locking block 4, a sliding frame 5, and a rotating shaft 6. The filter box 2 is mounted on the main body 1 and detachably connected to the main body 1. The spring 3 is fixedly mounted in the filter box 2, and its other end is fixedly connected to the locking block 4. The sliding frame 5 is mounted on the filter box 2 and slidably connected to the filter box 2. The rotating shaft 6 is mounted on the filter box 2 and rotatably connected to the filter box 2. The turbulence mechanism includes a rotating frame 7, a turbulence rod 8, a vertical plate 9, and a feed box 10. The rotating frame 7 is mounted in the main body 1 and rotatably connected to the main body 1. The turbulence rod 8 is fixedly mounted inside the main body 1. The vertical plate 9 is arranged on the rotating frame 7 and distributed in a linear array on the rotating frame 7. The feed box 10 is fixedly mounted inside the main body 1.

[0031] In this embodiment, the quick-release mechanism includes a filter box 2, a spring 3, a locking block 4, a sliding frame 5, and a rotating shaft 6. In use, the filter box 2 is installed in the feed box 10 of the main body 1, and the locking block 4 is connected to the locking hole 23. When the sliding frame 5 is pulled, the first limiting block 24 on the sliding frame 5 slides in the first limiting groove 27 of the filter box 2. As the sliding frame 5 slides, the connecting strip 25 connecting the sliding frame 5 and the locking block 4 at both ends slides in the rotating groove 26 of the rotating shaft 6, thereby pulling the locking block 4 to slide in the sliding frame 5. At this time, the spring 3 is compressed, and the second limiting block 29 on the locking block 4 slides in the second limiting groove 28. At the same time, the sliding of the locking block 4 on the filter box 2 causes the locking block 4 to disengage from the locking hole 23 on the main body 1, so that the filter box 2 can be removed from the main body 1. After the filter box 2 is removed, the suspended matter in the filter box 2 can be removed, and the filter box 2 can be put back.

[0032] In this embodiment, the turbulence mechanism includes a rotating frame 7, a turbulence rod 8, a vertical plate 9, and a feed box 10. During use, the water flow control mechanism operates. When the amount of wastewater being treated is small, the water flow will not pass through the layered plate 22 of the main body 1. When the water volume is extremely large, the door plate 12 is fully opened, allowing the wastewater to enter the main body 1 and, under the action of the layered plate 22, to enter different areas. To prevent damage to the rotating frame 7 due to water flow impact, the water flow first contacts the turbulence rod 8 after entering the main body 1, dispersing the water flow. Then, it contacts the rotating frame 7, pushing the rotating frame 7 to rotate inside the main body 1. Under the action of the vertical plate 9, the rotating frame 7 generates centrifugal force while rotating, directly throwing the suspended matter attached to the wastewater into the feed box 10. Subsequently, it enters the filter box 2 and remains there. The water flow either filters out the suspended matter in the filter box 2 or, after the suspended matter is thrown into the feed box 10, flows out at the bottom of the main body 1.

[0033] In this embodiment, the water flow control mechanism includes a frame 11, a door panel 12, a drive motor 13, a lead screw 14, an electric push rod 15, and an anti-blocking plate 16. In use, the drive motor 13 operates, directly driving the lead screw 14 to rotate, so that the positioning block 20 on the connecting plate 18 can slide in the positioning groove 19 in the support frame 17, thereby pulling the door panel 12 up in the frame 11. When the door panel 12 rises to a certain height, the electric push rod 15 pushes the anti-blocking plate 16 located in the placement groove 21, so that the anti-blocking plate 16 can extend and retract out of the frame 11, thereby reducing the blockage of suspended objects inside the frame 11. When the door panel 12 needs to fall back, the electric push rod 15 operates, directly retracting the anti-blocking plate 16, while the drive motor 13 on the support frame 17 drives in the opposite direction, directly sending the door panel 12 back in the opposite direction.

[0034] Example 2:

[0035] In summary, during use, the drive motor 13 first rotates, directly driving the lead screw 14 to rotate, allowing the positioning block 20 on the connecting plate 18 to slide in the positioning groove 19 in the support frame 17, thereby pulling the door panel 12 up within the frame 11. When the door panel 12 rises to a certain height, the electric push rod 15 pushes the anti-blocking plate 16 located in the placement groove 21, allowing the anti-blocking plate 16 to extend and retract out of the frame 11, thus reducing the blockage of suspended objects inside the frame 11. When the door panel 12 needs to fall back, the electric push rod 15 rotates, directly retracting the anti-blocking plate 16, while the drive motor 13 on the support frame 17 drives in the opposite direction, directly sending the door panel 12 in the opposite direction. When the water flow control mechanism is operating, if the amount of wastewater being treated is small, the water flow will not pass through the layered plate 22 of the main body 1. When the water volume is extremely large, the door plate 12 is fully opened, allowing the wastewater to enter the main body 1 and, under the action of the layered plate 22, to enter different areas. Simultaneously, to prevent damage to the rotating frame 7 due to water flow impact, the water flow, after entering the main body 1, first contacts the turbulence rod 8 to disperse the water flow, and then contacts the rotating frame 7, pushing the rotating frame 7 to rotate inside the main body 1. Under the action of the vertical plate 9, the rotating frame 7 generates centrifugal force while rotating, directly throwing the suspended solids attached to the wastewater into the feed box 10. Furthermore, the material accumulates in the filter box 2. When it accumulates to a certain extent, the filter box 2 is then installed in the feed box 10 of the main body 1. At this time, the locking block 4 is connected with the locking hole 23. When the sliding frame 5 is pulled, the first limiting block 24 on the sliding frame 5 slides in the first limiting groove 27 of the filter box 2. As the sliding frame 5 slides, the connecting strip 25 connecting the sliding frame 5 and the locking block 4 at both ends slides in the rotating groove 26 of the rotating shaft 6, thereby pulling the locking block 4 to slide in the sliding frame 5. At this time, the spring 3 is compressed, and the second limiting block 29 on the locking block 4 slides in the second limiting groove 28. Simultaneously, the sliding of the locking block 4 on the filter box 2 causes the locking block 4 to slide. The filter box 2 can be removed from the main body 1 by disengaging the clip 23 on the main body 1. After the filter box 2 is removed, the suspended matter in the filter box 2 can be removed. The filter box 2 can then be put back in. The water flows out after the suspended matter is filtered out by the filter box 2, or after the suspended matter is thrown into the feed box 10, it flows out from the bottom of the main body 1. (The suspended matter to be removed in this device is mostly suspended matter with a high water density, such as silt, as well as heavier particles that may be contained in industrial wastewater, such as iron filings, ceramic fragments, and sludge formed by sediment. Each time the door panel 12 is opened, the door panel 12 is raised to the highest position to reduce the impact of water flow on the door panel 12 when entering the main body 1.)

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
