Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a filtration device for wastewater treatment. Background Technology
[0002] Wastewater treatment filtration devices are a crucial component of modern environmental protection technology. Their main function is to remove pollutants such as suspended solids, particulate matter, organic matter, and some heavy metal ions from wastewater to protect and improve the environment. Wastewater treatment filtration devices mainly use physical or biochemical methods to deeply treat wastewater, ensuring that the discharged wastewater meets relevant environmental standards, reducing pollution to the environment, and protecting and improving the ecological environment.
[0003] Traditional sedimentation tank backwashing systems may lack sufficient auxiliary equipment to improve washing efficiency. For example, the lack of a combined air and water flushing device means that relying solely on water flushing is insufficient to thoroughly remove some highly adsorbed impurities or tightly packed sludge. Furthermore, the absence of an effective sludge collection and rapid drainage system after backwashing causes sludge to remain in the tank for too long, leading to re-sedimentation and affecting cleaning effectiveness. Some traditional sedimentation tanks also have simple backwashing system designs, resulting in uneven distribution of backwash water during the backwashing process. This may be due to an unreasonable layout of the backwashing pipes or improper setting of the number and angle of the nozzles. Traditional sedimentation tanks often require cleaning personnel to enter the tank through narrow manholes, relying solely on manual operation within a limited space, increasing cleaning difficulty and hazard.
[0004] Therefore, there is an urgent need for a filtration device for wastewater treatment to improve the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to provide a filtration device for wastewater treatment to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides a filtration device for wastewater treatment, including a sedimentation component. The sedimentation component includes a sedimentation tank with a smooth inner surface. A discharge component for discharging dirt from the sedimentation tank is fixedly connected to the lower end of the sedimentation tank's lower surface. A cleaning component is fixedly connected inside the sedimentation tank. The cleaning component includes an air pump, with an air pipe fixedly connected to one end of the air pump and a cleaning pipe fixedly connected to the other end. The cleaning pipe is fixedly connected to the inner surface of the sedimentation tank, and several nozzles are fixedly connected to the surface of the cleaning pipe for blowing air and spraying water. A water pipe is fixedly connected to the surface of the cleaning pipe, and a water pump is fixedly connected to the other end of the water pipe.
[0007] As a further improvement to this technical solution, an inlet is fixedly connected to one side of the sedimentation tank, and a drain is fixedly connected to the end of the sedimentation tank away from the inlet. The inlet is higher than the drain. A support leg is fixedly connected to the lower surface of the sedimentation tank, and a bracket is fixedly connected to the support leg.
[0008] As a further improvement to this technical solution, the air pump and water pump are fixedly connected to the upper surface of the support, and check valves are fixedly connected to the surfaces of the water pipe and air pipe. The check valves are used to prevent liquid backflow. A fixing frame is fixedly connected to the inner surface of the sedimentation tank. The fixing frame is used to fix the cleaning pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This wastewater treatment filtration device utilizes a combination of air and water for cleaning, which, compared to methods that rely solely on large amounts of chemical cleaning agents or high-energy-consuming cleaning equipment, not only saves on chemical usage and reduces potential environmental pollution, but also features relatively low energy consumption for the air and water pumps. This achieves both high-efficiency cleaning and energy conservation. The efficient sedimentation, sewage discharge, and self-cleaning mechanisms work synergistically to significantly reduce the erosion and damage of the sedimentation tank structure by dirt. Reduced dirt residue means a lower likelihood of corrosion of the tank materials due to long-term contact with pollutants, and it also avoids problems such as uneven tank pressure caused by dirt accumulation.

[0020] 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.
[0021] Please see Figures 1-4 As shown, this embodiment provides a filtration device for wastewater treatment, including a sedimentation component 1. The sedimentation component 1 includes a sedimentation tank 10, the lower end face of which forms a 15-degree angle with the horizontal plane. The inner surface of the sedimentation tank 10 is smooth. A sludge discharge component 3 is fixedly connected to the lower end of the lower surface of the sedimentation tank 10. The sludge discharge component 3 is used to discharge the dirt inside the sedimentation tank 10. A cleaning component 2 is fixedly connected to the sedimentation tank 10. The cleaning component 2 is used inside the sedimentation tank 10. The cleaning component 2 includes an air pump 20. One end of the air pump 20 is fixedly connected to an air pipe 21. The other end of the air pipe 21 is fixedly connected to a cleaning pipe 23. The cleaning pipe 23 is fixedly connected to the inner surface of the sedimentation tank 10. Several nozzles 24 are fixedly connected to the surface of the cleaning pipe 23. The nozzles 24 are used for blowing air and spraying water. A water pipe 26 is fixedly connected to the surface of the cleaning pipe 23. The other end of the water pipe 26 is fixedly connected to a water pump 25.
[0022] The working principle is as follows: Wastewater first enters the sedimentation tank 10. Because the lower end of the sedimentation tank 10 forms a 15-degree angle with the horizontal plane, the dirt in the wastewater will accumulate towards the lower end under the action of gravity. The smooth inner surface of the sedimentation tank 10 effectively reduces dirt adhesion and makes the sedimentation process smoother. When it is necessary to clean the sedimentation tank 10, the sewage discharge component 3 comes into play, and when opened, it can discharge the dirt accumulated at the lower end of the sedimentation tank 10. At the same time, the cleaning component 2 is activated, the air pump 20 operates, and the gas is transported to the cleaning pipe 23 through the air pipe 21, and then blown out by several nozzles 24 on the surface of the cleaning pipe 23. The powerful airflow impacts the inner surface of the sedimentation tank 10, which can loosen and remove some stubborn dirt. At the same time, the water pump 25 runs, drawing external clean water or the supernatant of the sedimentation tank 10 itself. The water flows into the cleaning pipe 23 through the water pipe 26 and is finally sprayed out from the nozzles 24. The high-pressure water flow and airflow work together to thoroughly and powerfully flush the walls and bottom of the sedimentation tank 10, completely removing dirt and ensuring that the sedimentation tank 10 always maintains a good working condition, providing a reliable guarantee for the subsequent sewage treatment process.
[0023] To facilitate wastewater sedimentation, in this embodiment, an inlet 11 is fixedly connected to one side of the sedimentation tank 10, and an outlet 12 is fixedly connected to the end of the sedimentation tank 10 furthest from the inlet 11. The inlet 11 is higher than the outlet 12. A support leg 13 is fixedly connected to the lower surface of the sedimentation tank 10, and a bracket 14 is fixedly connected to the support leg 13. When wastewater needs treatment, it enters the tank through the higher inlet 11 on one side. Because the inlet 11 is higher than the outlet 12, the wastewater flows slowly from the inlet 11 to the outlet 12 under gravity. During this process, the water flow velocity is controlled by the height difference, allowing sufficient time for suspended particles in the wastewater to settle in the tank. The lower end face of the sedimentation tank 10 forms a 15-degree angle with the horizontal plane, further facilitating the movement of dirt along the inclined bottom towards the lower end. The support leg 13 on the lower surface of the sedimentation tank 10 and the bracket 14 fixedly connected to the support leg 13 provide a stable support structure for the entire sedimentation tank 10.
[0024] To clean the interior of the sedimentation tank, in this embodiment, air pump 20 and water pump 25 are fixedly connected to the upper surface of bracket 14. Check valves 22 are fixedly connected to the surfaces of water pipe 26 and air pipe 21 to prevent backflow. A mounting bracket 27 is fixedly connected to the inner surface of sedimentation tank 10 to secure the cleaning pipe 23. When sedimentation tank 10 needs cleaning, air pump 20 and water pump 25, fixedly connected to the upper surface of bracket 14, are activated. Gas generated by air pump 20 is transmitted through air pipe 21, and water is transported through water pipe 26 by water pump 25; both flow to the cleaning pipe 23. The check valves 22 on the surfaces of air pipe 21 and water pipe 26 play a crucial role in preventing liquid backflow into the pump body during cleaning and ensuring a unidirectional and stable flow of gas and water to the cleaning pipe 23. The cleaning pipe 23 is securely installed using the mounting bracket 27 fixed to the inner surface of sedimentation tank 10, allowing for precise positioning of its nozzle 24. The powerful airflow blown by the air pump 20 impacts the inner surface of the sedimentation tank 10, loosening stubborn dirt. Then, the high-pressure water flow provided by the water pump 25 is sprayed out from the nozzle 24, working in conjunction with the airflow to thoroughly flush the tank walls and bottom, completely removing the dirt and ensuring that the sedimentation tank 10 can be restored to its optimal working condition at any time.
[0025] In order to discharge the sludge in the pool, the sewage discharge component 3 in this embodiment includes a sewage discharge chamber 30, which is fixedly connected to the lower surface of the sedimentation tank 10 and communicates with the sedimentation tank 10. A support leg 32 made of rubber is fixedly connected to the lower surface of the sewage discharge chamber 30. A motor 31 is fixedly connected to one end of the sewage discharge chamber 30, and a spiral push rod 33 is fixedly connected to the output shaft of the motor 31. A slide groove 34 is fixedly connected to the other end of the sewage discharge chamber 30, and a chamber door 35 is slidably connected to the slide groove 34. The chamber door 35 has a surface... The sewage discharge assembly 3 starts operating when the sludge settled at the bottom of the sedimentation tank 10 needs to be discharged. The motor 31 at one end of the sewage discharge chamber 30 starts, driving the spiral push rod 33 on the output shaft to rotate. The spiral push rod 33 is like a powerful "bulldozer", continuously pushing the sludge accumulated in the sewage discharge chamber 30 forward. The operator holds the handle 36 on the surface of the chamber door 35 and pulls the chamber door 35 upward to clean out the sludge in the chamber. After that, the chamber door 35 is closed to ensure that the sewage discharge system is always available.
[0026] In this embodiment, a wastewater treatment filtration device is used such that wastewater first enters the sedimentation tank 10 through the inlet 11, which is located at a higher position on one side. Since the inlet 11 is higher than the outlet 12, the wastewater flows slowly from the inlet 11 to the outlet 12 under gravity. During this process, the water flow velocity is controlled by the elevation difference, allowing sufficient time for suspended particles in the wastewater to settle within the tank. The lower end face of the sedimentation tank 10 forms a 15-degree angle with the horizontal plane, further facilitating the movement of dirt along the inclined bottom towards the lower end. The support legs 13 on the lower surface of the sedimentation tank 10 and the brackets 14 fixedly connected to the support legs 13 provide a stable support structure for the entire sedimentation tank 10. When the sedimentation tank 10 needs cleaning, the air pump 20 and water pump 25 fixedly connected to the upper surface of the bracket 14 are activated. The gas generated by the air pump 20 is transmitted through the air pipe 21, and the water pipe 26, driven by the water pump 25, delivers water to the cleaning pipe 23. The check valves 22 on the surfaces of the air pipe 21 and water pipe 26 play a crucial role in preventing liquid from flowing back into the pump body and causing damage during the cleaning process, ensuring that the gas and water flow unidirectionally and stably to the cleaning pipe 23. The cleaning pipe 23 is securely installed with the help of the fixing bracket 27 fixed to the inner surface of the sedimentation tank 10, so that its nozzle 24 can be accurately positioned. The powerful airflow from the air pump 20 impacts the inner surface of the sedimentation tank 10, loosening stubborn dirt. Subsequently, the high-pressure water flow provided by the water pump 25 is sprayed from the nozzle 24, working in conjunction with the airflow to thoroughly flush the tank walls and bottom, completely removing the dirt and ensuring that the sedimentation tank 10 can always return to its optimal working condition. When the dirt settled at the bottom of the sedimentation tank 10 needs to be discharged, the sewage discharge component 3 starts operating. The motor 31 at one end of the sewage discharge chamber 30 starts, driving the spiral push rod 33 on the output shaft to rotate. The spiral push rod 33 acts like a powerful "bulldozer," continuously pushing the dirt accumulated in the sewage discharge chamber 30 forward. The operator holds the handle 36 on the surface of the chamber door 35 and pulls the chamber door 35 upward to clean out the dirt inside. Afterward, the chamber door 35 is closed to ensure that the sewage discharge system is always available and that the sedimentation tank 10 always maintains a good working condition, providing a reliable guarantee for the subsequent sewage treatment process.
