Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a sewage discharge device for ultrafiltration dosing pipeline. Background Technology

[0002] In ultrafiltration membrane water treatment systems, the sodium hypochlorite dosing device is a key component for inhibiting microbial growth and preventing membrane fouling. Injecting sodium hypochlorite solution into the ultrafiltration membrane via a dosing pump effectively kills bacteria and algae, delays membrane module clogging, and extends its service life. However, during long-term operation, scale (such as hypochlorite crystals or calcium and magnesium deposits) easily forms on the inner wall of the dosing pipe, and residual chemicals may corrode the pipe wall, leading to the following problems:

[0003] Pipeline blockage risk: Scale buildup can gradually reduce pipe diameter or even completely block the pipe, affecting the normal operation of the dosing system. Forcibly increasing pump pressure to maintain flow in this situation could cause the pipe to burst, resulting in chemical leakage.

[0004] Safety hazards: Sodium hypochlorite solution is highly corrosive. If leaked, it may burn operators, and contact with the eyes can cause serious damage or even blindness.

[0005] High maintenance costs: Traditional cleaning methods require shutting down the machine to disassemble the pipes and manually clean or replace them, which is not only inefficient but also increases maintenance costs and system downtime.

[0006] In existing technologies, regular flushing or chemical cleaning is usually used to alleviate blockages, but these methods cannot achieve real-time online cleaning and have limited cleaning effects. Utility Model Content

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sewage discharge device for ultrafiltration dosing pipelines.

[0009] The cleaning component has a first state and a second state;

[0010] When the cleaning component is in the first state, the floating plate rises and the cleaning brush slides on the inner wall of the dosing pipe.

[0011] When the cleaning component is in the second state, the floating plate descends and the cleaning brush slides on the inner wall of the dosing pipe.

[0012] Preferably, a support plate is provided below the dosing pipe, and several dosing pipes are installed on the support plate, with the side wall of the support plate fitting against the inner wall of the dosing tank.

[0013] Preferably, a filter plate is provided below the support plate, the filter plate is attached to the inner wall of the dosing tank, and a buffer is provided on the end face of the filter plate.

[0014] Preferably, the buffer is a buffer plate, and the end face of the filter plate has a groove, and the buffer plate is installed in the groove by a rotating shaft.

[0015] Preferably, the dosing pipe extends outside the dosing tank and is provided with a fixing sleeve.

[0016] Preferably, an ultrafiltration backwash header is provided below the filter plate, and the output end of the ultrafiltration backwash header corresponds to the buffer plate.

[0017] Preferably, the side wall of the dosing tank is provided with a hypochlorous acid pipe, which extends into the dosing tank and is connected to the ultrafiltration backwash main pipe.

[0020] Preferably, the side wall of the dosing tank is provided with a drain door.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model uses a cleaning component design that links floating balls and floating plates to form a mechanical cleaning mechanism with periodic up-and-down movement inside the dosing pipeline. The reciprocating sliding of the cleaning brush on the inner wall of the pipeline can effectively remove scale (such as sodium hypochlorite crystals or calcium and magnesium deposits) and prevent pipeline blockage. The first state (rising) and the second state (falling) of the cleaning component form a two-way cleaning path, covering the entire area of ​​the inner wall of the pipeline, avoiding the dead corner problem of traditional one-way cleaning.

[0023] (2) By setting a support plate below the dosing pipe, the stability of the pipe installation is improved, and the pipe displacement or damage is prevented due to water flow impact or vibration. The combination design of the filter plate and the buffer can reduce the impact of water flow impact on the pipe and extend the service life of the equipment. The ultrafiltration backwash main pipe and the buffer plate work together to optimize the backwash water flow distribution, improve the cleaning effect, reduce ultrafiltration membrane pollution, and extend the membrane service life.

[0024] (3) This utility model connects the sodium hypochlorite dosing pump to the ultrafiltration backwash main pipe to ensure uniform dosing of bactericide, inhibit bacterial growth, and improve the bactericidal efficiency of the ultrafiltration system; the setting of the drain door and recovery pump facilitates system sewage discharge and agent recovery, reduces agent waste, and improves environmental protection; the buffer plate can be adjusted to adapt to different flow rate conditions and improve the system adaptability.

[0032] Please see Figure 1-4To achieve the above objectives, this embodiment provides a sewage discharge device for an ultrafiltration dosing pipeline 2, including a dosing tank 1. The dosing tank 1 is provided with a plurality of dosing pipelines 2 inside. The dosing pipelines 2 penetrate the dosing tank 1 and extend to the outside and are fixed by a fixing sleeve 9. The dosing pipelines 2 transport the chemical solution to the ultrafiltration system; the built-in cleaning component 3 realizes self-cleaning.

[0033] In this embodiment, the cleaning component 3 includes a floating ball 4, a floating plate 5, and a cleaning brush. The cleaning component 3 is nested inside the dosing pipe 2 and floats up and down with the liquid level. The floating ball 4 is driven by the buoyancy of the fluid, which triggers the floating plate 5 to rise and fall. The floating plate 5 drives the cleaning brush to move in both directions (rising / falling) to scrub the contaminants on the inner wall of the pipe. The cleaning brush physically scrapes off the adhering impurities to prevent the pipe from scaling and clogging.

[0034] In this embodiment, the support plate 6 is located below the dosing pipe 2 and fits against the inner wall of the tank. The support plate 6 fixes the array of dosing pipes 2 to ensure vertical stability and distributes the pipe load to prevent tank deformation.

[0035] In this embodiment, the filter plate 7 is located below the support plate 6 and is in close contact with the inner wall of the tank. The buffer plate 8 is embedded in the groove of the filter plate 7 through a rotating shaft. The filter plate 7 intercepts large particulate impurities and protects the downstream ultrafiltration backwashing main pipe 10.

[0036] In this embodiment, the buffer plate 8 dynamically adjusts the direction of water flow impact to prevent filter plate clogging; during backwashing, it guides the water flow to be evenly distributed.

[0037] In this embodiment, the ultrafiltration backwash main pipe 10 is located below the filter plate 7, with its output end aligned with the buffer plate 8. The ultrafiltration backwash main pipe 10 delivers backwash water or chemical cleaning agent (such as sodium hypochlorite) to backwash the dosing pipe 2 and the filter plate 7, thereby enhancing the sewage discharge effect.

[0038] In this embodiment, the hypochlorous acid pipeline 11 is connected to the side wall of the tank and extends to the ultrafiltration backwash main pipe 10. Sodium hypochlorite disinfectant is injected into the hypochlorous acid pipeline 11 to kill microorganisms and decompose organic matter; the dosing pump precisely controls the dosage of the agent.

[0039] In this embodiment, the recovery pump is located on the side wall of the tank, and the drain valve is located at the bottom of the tank. The recovery pump recycles uncontaminated cleaning solution, reducing waste, while the drain valve centrally discharges cleaning waste liquid and shed dirt, facilitating maintenance.

[0040] Working principle

[0041] Dosing phase:

[0042] The liquid medicine is delivered to the ultrafiltration system through the dosing pipe 2. The floating ball 4 is raised by the liquid level, which drives the floating plate 5 to rise. The cleaning brush moves upward in sync, and initially scrapes the inner wall of the pipe.

[0043] When the pressure inside the pipeline drops or the system detects an abnormal flow rate, the backwashing procedure is initiated. High-pressure water is injected into the ultrafiltration backwash header 10, impacting the buffer plate 8 and causing it to deflect. The water flow evenly washes the filter plate 7, dispersing accumulated impurities. The sodium hypochlorite dosing pump is started, and hypochlorous acid solution enters the backwash header through the pipeline. After mixing with the backwash water, it is sprayed onto the buffer plate 8 to sterilize and disinfect the pipeline and filter plate 7. The floating ball 4 descends with the change in backwash liquid level, driving the floating plate 5 and brush to move down, and then brushing the inner wall of the pipeline a second time to remove residual dirt. The bidirectional movement (rising / falling) of the cleaning brush forms a "reciprocating scraping" motion, improving the cleaning coverage. The detached dirt is intercepted by the filter plate 7 with the backwash water flow, and large particles are discharged through the drain door after deposition. Some of the cleaning solution is reintroduced into the dosing tank 1 through the recovery pump to achieve resource recycling.

[0044] In other embodiments, pressure and flow sensors are installed on the inner wall of the dosing pipeline 2 to monitor the risk of blockage in real time and trigger an automatic cleaning program.

[0045] ‌

[0046] In other embodiments, a detachable coarse filter screen is added at the inlet of the dosing tank 1 to intercept fibers and suspended solids, thereby reducing the load on the main filter plate 7.

[0047] In other embodiments, activated carbon or ceramic filter elements are installed in front of the drain gate to ensure that the discharged water meets the standards.

[0048] In other embodiments, a magnet is embedded in the floating ball 4, which is linked with an electromagnetic coil outside the pipe to achieve precise lifting control.

[0049] In other embodiments, the backwash water flow is directed to a turbine generator to convert water pressure energy into electrical energy, which is then supplied to sensors or control systems.

[0050] In other embodiments, a heat exchange tube is wrapped around the hypochlorous acid pipeline 11 to preheat the solution using backwash hot water, thereby reducing heating energy consumption.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
