Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an integrated vacuum multiple rinsing device. Background Technology

[0002] Under extreme rainfall conditions, stormwater storage tanks in urban drainage systems can easily reach their designed maximum capacity. At this point, due to the carrying effect of the water flow, a large amount of suspended impurities and particulate matter accumulates at the bottom of the tank, forming a thick layer of silt. This sedimentation process not only significantly reduces the effective water storage space of the tank, weakening its ability to regulate and store water in response to extreme rainfall events, but also triggers the decomposition of organic matter in the water, leading to a sharp drop in dissolved oxygen levels, an increase in ammonia nitrogen concentration, and the formation of odorous substances such as sulfides. This, in turn, causes secondary environmental problems such as water quality deterioration and odor diffusion.

[0003] Traditional flushing processes often rely on external water supply or manual intervention, resulting in systemic technical drawbacks: First, the dependence on a continuous water supply leads to secondary water consumption, significantly increasing system energy consumption and treatment costs. Second, manual operation is limited by labor intensity and time constraints, making it difficult to achieve real-time dynamic removal of sediments, resulting in low cleaning efficiency and blind spots. Furthermore, traditional systems cannot perform multi-round flushing, making it difficult to handle complex conditions such as sediment compaction. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] In existing technologies, rainwater storage tanks in urban drainage systems are prone to reaching their capacity limits under extreme rainfall conditions. Accumulation of sediment at the bottom of the tanks reduces the effective water storage space, leading to significant water quality deterioration. Traditional flushing processes rely on external water sources or manual operation, resulting in water waste and low cleaning efficiency. For example, mechanical flushing devices often experience frequent malfunctions due to excessive transmission components, while manual cleaning struggles to achieve real-time dynamic removal and has blind spots.

[0018] To address the aforementioned issues, a device is needed that requires no external water source, has a simplified structure, and can automatically control the flushing process. Analysis of the application potential of atmospheric pressure difference and the siphon principle reveals that utilizing the rainwater from the storage tank itself as the flushing water source can eliminate external dependence. Further research into the vacuum formation and release mechanism proposes a multi-stage vacuum release approach to achieve multiple flushing cycles, thus resolving the problem of incomplete flushing caused by sediment compaction in a single wash.

[0019] A water storage chamber 101 is formed on one side of the regulating tank 100. The water storage chamber is equipped with a partition 102, which divides the water storage chamber into multiple water storage cavities S2. The water storage chamber is connected to the regulating tank via a communication port 103. An integrated vacuum multiple flushing device 200 is installed on the top of the water storage chamber. A float level gauge 104 is installed in the water storage chamber.

[0020] An integrated vacuum multiple rinsing device includes an annular shell 11, a lower plate 15 fixedly connected to the bottom of the annular shell, and a plurality of vacuum chambers S1 formed between the annular shell and the lower plate. Specifically, in this embodiment, two vacuum chambers are provided. An air inlet 131 is formed on the vacuum chamber, and a sealing mechanism is installed on the outer wall of the vacuum chamber. The sealing mechanism can be used to seal the air inlet. The vacuum chamber is connected to a vacuum tube 41. The lower plate is installed directly above the water storage chamber, and a plurality of connecting holes 151 that cooperate with the vacuum chamber are formed on the lower plate. The water storage chamber of the water storage chamber is connected to the vacuum chamber through the connecting holes.

[0021] The annular shell refers to the ring-shaped structure surrounding the vacuum chamber, which can be welded from corrosion-resistant metal materials to support internal components and form a sealed space. The lower plate is a flat plate structure fixed to the bottom of the annular shell, which can be connected by bolts or welding, and is used to separate the water chamber from the vacuum chamber. The vacuum chamber is the space enclosed by the annular shell, lower plate, and internal connecting plates, which can be formed by welding the upper connecting plate, side plates, and lower connecting plate, and is used to create a negative pressure environment. The sealing mechanism is the device that controls the opening and closing of the air inlet, which can be a structure with a support rod fixing a disc and a diaphragm installed. The air inlet is sealed by the deformation of the diaphragm driven by the inflation pipe. Specifically, during rainfall, the water levels in the regulating tank and the storage chamber rise synchronously. At this time, the diaphragm is not blocked from the air inlet, allowing air to circulate freely. When the water level reaches the preset level, the air pump inflates the air inlet, causing the diaphragm to bulge and block the air inlet. The vacuum pump then starts, extracting the air from the vacuum chamber. Since the vacuum chamber and the storage chamber are connected through a connecting hole, a negative pressure is created in the storage chamber. The atmospheric pressure in the regulating tank forces the water into the storage chamber to maintain a high level. When the regulating tank is emptied, the pressure in one vacuum chamber is released first, allowing air to enter the storage chamber through the air inlet. The high-level water is instantly discharged, completing the first round of flushing. Subsequently, the pressure in the other vacuum chamber is released for the second round of flushing, resolving the problem of incomplete flushing caused by sediment compaction. Compared to existing technologies, traditional flushing devices require an additional water supply and rely on complex mechanical transmissions. This solution utilizes the pressure difference between the rainwater in the storage tank and atmospheric pressure to achieve flushing, eliminating the need for external energy consumption. Existing equipment typically uses a single flushing unit, while this application achieves multiple flushing cycles through multiple vacuum chambers, significantly improving sediment removal efficiency. Furthermore, a diaphragm sealing mechanism replaces the traditional valve structure, reducing the number of moving parts and lowering failure rates and maintenance costs. Through the above technical solution, this application effectively utilizes rainwater resources to complete automatic flushing, reducing manual intervention and dependence on external energy; the phased vacuum release design enhances the flushing effect on compacted deposits; the simplified sealing structure and control components reduce equipment complexity and extend service life.

[0022] In at least one embodiment, the vacuum chamber includes an upper connecting plate 12, a side plate 13, and a lower connecting plate 14. The upper connecting plate is welded to the inner wall of the annular shell. The upper connecting plate is connected to the side plate, and the side plate is connected to the lower connecting plate. The lower connecting plate is fixedly connected to the lower plate. The upper connecting plate, the side plate, the lower connecting plate, the annular shell, and the lower plate are spliced ​​to form a sealed cavity. The sealed cavity has an air inlet, a connecting hole, and a vacuum tube for evacuation.

[0023] Furthermore, an air inlet is formed on the side panel.

[0024] In at least one embodiment, the sealing mechanism includes a support rod 51, which is fixedly connected to a side plate. A disk 52 is installed at the end of a plurality of the support rods. A diaphragm 53 is provided on the side of the disk near the air inlet. A central hole is provided on the disk. An inflation pipe 61 is connected to the central hole. An air pump is connected to the inflation pipe. The diaphragm can inflate under the action of the air pump to seal the air inlet.

[0025] The support rod is a rigid connector vertically fixed to the side plate surface, typically made of welded metal, used to provide a mounting reference for the disc and maintain structural stability. The disc is a disk-shaped component with a central through-hole, typically made of stamped stainless steel, its circumferential edges fixed to the side plate via the support rod, used to support the diaphragm and form an airtight cavity. The diaphragm is a sealing element with elastic deformation capability, typically made of rubber or silicone, deformed by an air pump, used to selectively seal the air inlet channel. The inflation tube is a flexible conduit connecting the central hole of the disc to the air pump, typically made of polyurethane hose, used to transmit compressed air to control the diaphragm's deformation. Specifically, when the air pump delivers compressed air to the central hole of the disc through the inflation pipe, the diaphragm expands outward under the air pressure until it forms a surface contact seal with the inner wall of the air inlet, at which point the vacuum chamber is isolated from the outside air. When it is necessary to release the seal, the air pump stops supplying air and releases the pipeline pressure. The diaphragm returns to its initial state due to its own elasticity, and air enters the vacuum chamber through the air inlet. This process achieves non-contact sealing through air pressure control, avoiding seal failure caused by mechanical wear. In at least one embodiment, the top of the annular shell is provided with a breathable stainless steel mesh cover 2, and the breathable stainless steel mesh cover is provided with a plurality of breathable mesh holes.

[0026] The breathable stainless steel mesh cover refers to a mesh-like covering structure made of stainless steel, specifically 316L stainless steel perforated plate. Its function is to provide a gas flow channel while preventing solid impurities from entering the equipment. The breathable mesh refers to a perforated structure evenly distributed on the surface of the mesh cover, specifically created using laser cutting technology to form holes with diameters ranging from 0.5 to 2 millimeters. By controlling the hole size, the breathability and filtration performance are balanced. Furthermore, the vacuum tube is connected to a vacuum pump.

[0027] Furthermore, both the vacuum tube and the inflation tube are equipped with control valves.

[0028] Specifically, during vacuum flushing operations, when a vacuum environment needs to be established, the control valve of the vacuum extraction tube opens, allowing the vacuum pump to evacuate the vacuum chamber through the extraction tube. When the water storage chamber needs to be flushed by releasing the vacuum, the control valve of the vacuum extraction tube closes to block the vacuum maintenance path, while the control valve of the inflation tube adjusts the vacuum release rate. The coordinated action of the two control valves allows for precise, staged control of the vacuum establishment and release processes. For example, in dual-chamber flushing mode, by alternately opening and closing the control valves of different vacuum extraction tubes, the independent vacuum release sequence of the two water storage chambers can be achieved. The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
