Description
Technical Field
[0001] This utility model relates to the technical field of sewage treatment facilities, and in particular to a sewage collection and pretreatment facility for municipal buildings. Background Technology
[0002] Municipal building wastewater collection involves gathering various types of wastewater generated within urban buildings, such as domestic sewage and industrial wastewater, through underground pipeline systems. Wastewater collection pretreatment facilities are used to perform preliminary treatment on this wastewater. They can remove large particulate impurities, sand, and some suspended solids from the wastewater, reducing the difficulty of subsequent wastewater treatment, improving treatment efficiency, ensuring the stable operation of the entire wastewater treatment system, reducing the risk of environmental pollution, and facilitating resource recycling.
[0003] Traditional wastewater collection and pretreatment systems mainly consist of an inlet channel, a screen, a grit chamber, and a sedimentation tank. The inlet channel introduces the wastewater, while the screen, typically made of metal bars, intercepts larger solid debris. The grit chamber uses flow rate control and a special design to settle heavier inorganic particles such as sand. The sedimentation tank allows the wastewater to remain for an extended period, causing suspended solids to settle to the bottom. These components work in sequence to perform preliminary purification of the wastewater.
[0004] From a structural perspective, traditional wastewater collection and pretreatment facilities are prone to sludge and other impurities accumulating inside. Because the spacing of their bar screens is relatively fixed, it's difficult to precisely accommodate impurities of different sizes, allowing some small debris to easily pass through and enter subsequent stages. Grit chambers have limited aeration or mixing effects, failing to completely separate sand particles from wastewater, leaving some sand residue. The structure of sedimentation tanks causes sludge to accumulate in bottom corners or areas with slow water flow, making it difficult to remove. This accumulation reduces treatment efficiency, increases the risk of equipment blockage, affects the activity of microorganisms in subsequent biological treatment, and also causes wastewater overflows that pollute the surrounding environment, increasing maintenance costs and complexity. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a municipal building sewage collection and pretreatment mechanism, which aims to improve the problems of traditional sewage collection and pretreatment mechanisms that are prone to sludge and other impurities accumulating inside, causing sewage overflow and polluting the surrounding environment, and increasing maintenance costs and difficulties.

[0024] 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.
[0025] Reference Figure 1-Figure 2An embodiment of this utility model is provided: a municipal building sewage collection and pretreatment mechanism, including a treatment box 1, which is the core container of the entire sewage or other fluid treatment system. A water inlet platform 12 is fixedly connected to the top of the treatment box 1. The water inlet platform 12 is the inlet of sewage or other fluid into the treatment box 1. A decontamination component is provided inside the treatment box 1, and a drainage component is provided on the side wall of the treatment box 1. The drainage component is used to discharge sewage.
[0026] The cleaning assembly includes a support platform 2, which supports and secures other components within the treatment box 1. The bottom of the support platform 2 is fixedly connected to the inside of the treatment box 1. A motor 3 is fixedly connected to the bottom of the support platform 2, and a cam 4 is fixedly connected to the output end of the motor 3. Multiple side plates 5 are fixedly connected to the upper surface of the support platform 2. The side plates 5 provide vertical guidance and support for components such as the slide table 6 and slide column 9. The slide table 6 is slidably connected between the side plates 5. Under the action of the cam 4, the slide table 6 reciprocates linearly along the side plates 5. A ram 7 is fixedly connected, and a connecting platform 8 is fixedly connected to the upper surface of the support platform 2. A sliding column 9 is slidably connected inside the connecting platform 8. One end of the sliding column 9 is fixedly connected to the side wall of the sliding platform 6. A spring 10 is sleeved on the outer wall of the connecting platform 8. The spring 10 is compressed or stretched to store elastic potential energy. When the external force disappears, the spring 10 releases the elastic potential energy and pushes the sliding column 9 back to its original position. A push plate 11 is fixedly connected to one end of the sliding column 9 to push solid impurities or sediments in the processing box 1 to concentrate them in a specific area for cleaning.
[0027] Specifically, when it is necessary to clean the sludge and other debris inside the treatment box 1, the relevant personnel start the motor 3. Once the motor 3 is started, it will first output power to the cam 4, causing the cam 4 to start rotating. During the continuous rotation of the cam 4, its side wall will periodically contact and interact with the impact plate 7, thereby repeatedly pushing the impact plate 7. After the impact plate 7 is pushed by the cam 4, it will cause the slide 6 connected to its side wall to repeatedly slide within the space defined by the side plate 5. This sliding action of the slide 6 will further drive the sliding column 9 on its side wall to slide accordingly inside the connecting platform 8. During the sliding process, column 9 will randomly drive the push plate 11 on its side wall to clean the sludge and other impurities inside the treatment tank 1. Furthermore, under the tension of spring 10, it can be ensured that column 9 can be smoothly reset after completing one pushing and cleaning action, thus preparing for the next pushing and cleaning. This cyclical cleaning process can ensure the normal operation of the equipment, ensure that the sewage can flow smoothly and continuously in the pretreatment mechanism, effectively avoid the interruption of sewage collection and treatment due to equipment failure, and enable the entire sewage treatment process to proceed stably and orderly.
[0028] Reference Figure 3 and Figure 4The drainage assembly includes a connecting compartment 13, which serves as a transition connection between the treatment tank 1 and the drainage structure. The connecting compartment 13 is fixedly connected to the side wall of the treatment tank 1. A fixed platform 14 is fixedly connected to the top of the connecting compartment 13. A rotating wheel 15 is rotatably connected to the side wall of the fixed platform 14. The rotating wheel 15 is a manually operated component. A gear 16 is fixedly connected to the side wall of the rotating wheel 15, and the gear 16 is rotatably connected inside the fixed platform 14. A sliding shaft 17 is slidably connected inside the fixed platform 14. The sliding shaft 17 slides vertically inside the fixed platform 14 under the push of a rack 18. A rack 18 is fixedly connected to the side wall of the sliding shaft 17, and the rack 18 meshes with the gear 16. The top of the sliding shaft 17... A second spring 19 is provided, with one end of the second spring 19 fixedly connected to the inside of the fixed platform 14 and the other end of the second spring 19 fixedly connected to the top of the sliding shaft 17. A drain pipe 20 is fixedly connected to the side wall of the connecting chamber 13. The drain pipe 20 is used to discharge the treated sewage or rainwater in the treatment tank 1 to a designated location. A drain chamber 21 is fixedly connected to the bottom of the drain pipe 20. The drain chamber 21 is a transition area for sewage during the discharge process. An eccentric column 22 is rotatably connected inside the drain chamber 21. Multiple arc-shaped plates 23 are rotatably connected to the outer wall of the eccentric column 22. The arc-shaped plates 23 are located on the outer wall of the eccentric column 22 and rotate with the rotation of the eccentric column 22, further enhancing the pushing and guiding effect on the water flow.
[0029] Specifically, when it is necessary to discharge the sewage inside the treatment tank 1, the relevant personnel rotate the rotating wheel 15. After being subjected to external force, the rotating wheel 15 will start to drive the gear 16 on its side wall to rotate inside the fixed platform 14. Since there is a meshing relationship between the gear 16 and the rack 18, the rotation of the gear 16 will further generate a pushing and pulling force on the sliding shaft 17, allowing the sliding shaft 17 to slide vertically inside the fixed platform 14. This vertical sliding of the sliding shaft 17 will then push the valve at the bottom, realizing the opening or closing operation of the connecting chamber 13, thereby achieving the purpose of sewage discharge. When the valve is opened, the sewage will then flow into the drainage chamber 21 through the drain pipe 20. The flow of sewage causes the eccentric column 22 to rotate inside the drainage chamber 21. The rotation of the eccentric column 22 further causes multiple arc-shaped plates 23 on its outer wall to rotate together. When these arc-shaped plates 23 rotate, they push the water flow, thereby preventing the water flow from forming eddies. The stable water flow state has a positive effect on maintaining a high drainage speed, enabling sewage or rainwater to be discharged more quickly. Especially during periods of heavy rainfall or when sewage discharge is at its peak, this efficient drainage characteristic can effectively prevent water accumulation and ensure that the relevant areas will not suffer from flooding or other adverse effects due to poor drainage, thus ensuring the normal operation of the entire drainage system and the safety and stability of the surrounding environment.
[0030] Working Principle: When it is necessary to clean the sludge and other debris inside the treatment tank 1, the motor 3 is started. After starting, the motor 3 first outputs power to the cam 4, causing the cam 4 to rotate. During the rotation, the cam 4 repeatedly pushes the impact plate 7 on its side wall. Under the force, the impact plate 7 moves the slide 6 on its side wall to slide repeatedly between the side plates 5. The sliding process of the slide 6 further drives the slide column 9 on its side wall to slide inside the connecting platform 8. During the sliding process, the slide column 9 drives the push plate 11 on its side wall to effectively clean the sludge and other impurities inside the treatment tank 1. The tension of the spring 10 ensures that the slide column 9 can drive the push plate 11 to reset and perform the next push cleaning. This ensures the normal operation of the sewage discharge, maintains the smooth flow of sewage in the pretreatment mechanism, and avoids the interruption of sewage collection and treatment due to equipment failure. When water is discharged, the rotating wheel 15 is rotated. Under force, the rotating wheel 15 drives the gear 16 on its side wall to rotate inside the fixed platform 14. The gear 16 meshes with the rack 18, which further pushes and pulls the sliding shaft 17, allowing the sliding shaft 17 to slide vertically inside the fixed platform 14. This, in turn, pushes the valve at the bottom to open or close the connecting chamber 13, thus discharging sewage. Subsequently, the sewage enters the drainage chamber 21 through the drain pipe 20, and drives the eccentric column 22 to rotate inside the drainage chamber 21. The rotation of the eccentric column 22 further drives the multiple arc-shaped plates 23 on its outer wall to rotate and push the water flow to discharge, preventing the water flow from forming eddies. The stable water flow helps maintain a high drainage speed, allowing sewage or rainwater to be discharged more quickly. Especially during periods of heavy rainfall or peak sewage discharge, efficient drainage can effectively prevent water accumulation.
