Technical Field

[0001] This utility model relates to the field of combined sewer system sewage interception technology, specifically a combined sewer overflow pollution control and treatment device. Background Technology

[0002] A combined sewer system is a drainage system that mixes domestic sewage, industrial wastewater, and rainwater in the same pipeline system for transportation. Combined sewer overflow pollution control and treatment devices can effectively remove suspended solids, organic matter, and some nutrients from sewage through processes such as sedimentation, filtration, and biological treatment, reducing the concentration and total amount of pollutants discharged, thereby mitigating pollution to receiving water bodies and improving the quality of the aquatic environment.

[0003] Chinese utility model patent CN220247117U discloses a combined sewer system overflow rainwater interception device, belonging to the field of combined sewer system interception. It includes: a filter box with an inlet at its upper end and a filtration mechanism extending to the outside installed inside; and a sewage discharge assembly. The sewage discharge assembly includes a grooved surface at the bottom of the filter box, with a sewage discharge trough at its lower end. A rotating rod is rotatably connected to the sewage discharge trough, and multiple spiral blades for use with the sewage discharge trough are fixedly installed on the rotating rod. A first scraper and a second scraper are slidably connected to the grooved surface. This utility model's grooved surface facilitates the flow of sludge into the sewage discharge trough. During the sewage discharge process, the rotating spiral blades allow for continuous relative and opposite movement of the first and second scraper blades, effectively treating the sludge on the grooved surface and directing it into the sewage discharge trough for more thorough sewage treatment.

[0004] To clean floating debris and particulate matter from the conveyor belt surface, the aforementioned combined sewer overflow stormwater interception device is equipped with a motor, active roller, passive roller, and scraper. However, this device does not have the function of collecting the cleaned impurities. If the fallen impurities are not collected in time, they will scatter around the interception device, polluting the surrounding environment. In addition, staff need to spend extra effort to clean and collect these scattered impurities, increasing labor costs. Utility Model Content

A conveyor belt 205 is provided outside the passive roller 201 and the active roller 203. A mounting plate 301 is provided below the fixed posts 202, and a collection box 302 is fixedly provided on the top of the mounting plate 301. The top of the collection box 302 has a receiving cavity, and both sides of the bottom of the inner wall of the receiving cavity have T-shaped grooves 303. A T-shaped slider 304 is movably arranged inside the T-shaped groove 303. The T-shaped slider 304 and the T-shaped groove 303 are slidably connected. A dust collection groove 305 is fixedly arranged on the top of the T-shaped slider 304. A maintenance plate 308 is movably arranged on the front of the filter box 1. Threaded holes are opened at the four corners of the maintenance plate 308, and fixing bolts 309 are movably arranged in the threaded holes. The fixing bolts 309 are movably inserted into the filter box 1.

[0021] Specifically, a scraper 206 is fixedly provided on the surface of the conveyor belt 205.

[0022] In this embodiment, by setting up a scraper 206, impurities remaining on the surface of the conveyor belt 205 can be cleaned, enhancing the practicality of the device.

[0023] Specifically, a handle 306 is fixedly provided in the middle of the front side of the dust collection tank 305.

[0024] In this embodiment, by providing a handle 306, a stable gripping point is provided, allowing workers to pull the dust collection trough 305 more smoothly, thus improving the convenience of disassembling and installing the dust collection trough 305.

[0025] Specifically, a support plate 307 is fixedly provided at the bottom of the mounting plate 301, and one end of the support plate 307 is fixedly connected to the outer wall of the filter box 1.

[0026] In this embodiment, by setting a support plate 307, the support plate 307 forms a triangular support structure through its connection with the bottom of the mounting plate 301 and the outer wall of the filter box 1, ensuring that the collection box 302 can operate stably for a long time.

[0027] Specifically, an inlet 401 is fixedly installed on the top of the filter box 1.

[0028] In this implementation scheme, by setting up an inlet 401, when overflow rainwater occurs in the combined sewer network, the rainwater can naturally flow into the filter box 1 through the inlet 401 under the action of gravity, thereby improving the efficiency of rainwater collection and treatment.

[0029] Specifically, a water outlet 402 is fixedly provided on the front of the filter box 1, and a sewage outlet 403 is fixedly provided on the bottom of one side of the filter box 1. Valves are provided inside both the water outlet 402 and the sewage outlet 403.

[0030] In this implementation plan, by setting up a water outlet 402 and a sewage outlet 403, and by adjusting the valves, the water flow and sludge discharge can be controlled, ensuring the continuous operation of the device.

[0031] In operation, wastewater enters the filter box 1 through the inlet 401. After being filtered by the conveyor belt 205, impurities remain on the surface of the conveyor belt 205, while the wastewater, now free of impurities, falls to the bottom of the filter box 1. Opening the valve allows the wastewater to drain through the outlet 402. Sludge in the wastewater accumulates in the arc-shaped trough. Opening the valve allows the sludge to drain through the drain outlet 403 under the action of the spiral blades. When the conveyor belt 205 needs cleaning, the motor 204 is started. The motor 204 drives the active roller 203 to rotate. With the cooperation of the passive roller 201, the conveyor belt 205 rotates clockwise. The scraper 206 moves the impurities along with the conveyor belt 205. When the impurities reach the rightmost end of the conveyor belt 205, they fall downwards and accurately into the dust collection trough 305, thus achieving the purpose of centralized collection of impurities. When the dust collection trough 305 needs cleaning, the operator... Simply pull the handle 306 outward to move the dust collection trough 305 within the collection box 302. Simultaneously, the T-shaped slider 304 slides within the T-shaped groove 303 to ensure the stability and safety of the dust collection trough 305 during movement. After the dust collection trough 305 is moved out of the collection box 302, disassembly of the dust collection trough 305 is completed. Conversely, the operation can be performed to install it. This provides great convenience for staff to clean the dust collection trough 305 regularly, effectively saving manpower and time costs. When it is necessary to maintain or repair the internal components of the device, turn the knob fixing bolt 309. When one end of it moves out of the filter box 1, the limit of the inspection plate 308 is released, and the inspection plate 308 can be removed, thus completing the disassembly of the inspection plate 308. Conversely, the operation can be performed to install it, thereby realizing the quick disassembly and installation of the inspection plate 308, so that staff can maintain and repair the internal components of the device.

[0032] In summary, this combined overflow pollution control and treatment device, through the installation of mounting plate 301, collection box 302, T-shaped chute 303, T-shaped slider 304, dust collection trough 305, handle 306, and support plate 307, provides stable support for collection box 302 by mounting plate 301 and support plate 307, facilitating the collection of impurities. When impurities on the surface of conveyor belt 205 fall downwards under the influence of gravity, they can accurately fall into dust collection trough 305, thereby achieving the purpose of centralized collection of impurities. This helps to prevent impurities from scattering around the device and reducing the risk of polluting the surrounding environment. When cleaning dust collection trough 305, pulling handle 306 outwards moves dust collection trough 305 within collection box 302, while T-shaped slider 304 slides within T-shaped chute 303. The movement of the dust collection trough 305 is designed to ensure its stability and safety. After the dust collection trough 305 is removed from the collection box 302, its disassembly is completed, and vice versa. This greatly facilitates the regular cleaning of the dust collection trough 305 by staff, effectively saving manpower and time costs. By setting up an inspection plate 308 and fixing bolts 309, and by turning the fixing bolts 309, when one end of the inspection plate 308 is removed from the filter box 1, the limit of the inspection plate 308 is released, and the inspection plate 308 can be removed, thus completing its disassembly. Conversely, it can be installed by turning it back. This enables the quick disassembly and installation of the inspection plate 308, facilitating the maintenance and repair of the internal components of the device by staff, reducing maintenance costs, and helping to ensure the normal operation of the equipment.
