Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment circulation device. Background Art

[0002] Wastewater treatment is a crucial component of modern environmental protection. Sewage typically contains a large amount of impurities, sludge, and particulate matter, which need to be effectively removed during the treatment process. Currently, gravity sedimentation is a common sewage treatment method. This method, based on the density difference between suspended matter and water, uses gravity to settle solid pollutants such as impurities, sludge, and particulate matter in sewage to the bottom of the sedimentation tank, while the treated clean water remains in the upper layer and is eventually discharged. This method is widely used in urban sewage treatment and industrial wastewater treatment due to its simple operation and low cost.

[0003] However, there are some problems with the practical application of gravity sedimentation. As sewage treatment continues, impurities, sludge and particulate matter will gradually accumulate at the bottom of the sedimentation tank, resulting in a reduction in sedimentation space and affecting sedimentation efficiency. To maintain the normal operation of the system, the sediment in the sedimentation tank must be cleaned regularly. At present, the cleaning process usually relies on manual or mechanical methods, which not only increases the workload and cost of maintenance, but also easily leads to frequent shutdowns of the treatment system, affecting the continuity and overall efficiency of sewage treatment. Therefore, the existing gravity sedimentation method has obvious deficiencies in automation and continuous processing capabilities, and is in urgent need of further improvement.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In addition, the term "and / or" in this article is only used to describe the association relationship of related objects in a sewage treatment circulation device, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previous and next related objects are in an "or" relationship.

[0029] like Figure 1 and Figure 7 As shown, the sewage treatment circulation device includes a filter barrel 1, a water supply pipe 2, a discharge mechanism 3, a sedimentation tank 4 and a drive mechanism 5. Among them, the side wall of the filter barrel 1 is a mesh structure, which can effectively intercept impurities, sludge and particulate matter in the sewage. One end of the filter barrel 1 is connected to the first support frame 11, and the other end is connected to the second support frame 12. The drive mechanism 5 is connected to the filter barrel 1 and is used to drive the filter barrel 1 to rotate along its axis. The discharge mechanism 3 is arranged inside the filter barrel 1 and is used to discharge the collected impurities, sludge and particulate matter.

[0030] One end of the water supply pipe 2 extends into the interior of the filter barrel 1 and is connected to the filter barrel 1 via a rotating connector, allowing it to maintain a stable connection with the interior of the filter barrel 1 during rotation. The water supply pipe 2 is provided with at least one sewage outlet 21 for conveying sewage into the interior of the filter barrel 1. A first support frame 11 and a second support frame 12 are respectively fixedly connected to the sedimentation tank 4 to support and stabilize the rotation of the filter barrel 1.

[0031] During use, the end of the water supply pipe 2 away from the filter barrel 1 is connected to an existing sewage pump (not shown). The sewage pump delivers sewage through the water supply pipe 2 into the filter barrel 1. The sewage is then discharged into the interior of the filter barrel 1 through the sewage outlet 21 on the water supply pipe 2. Subsequently, the drive mechanism 5 is activated, driving the filter barrel 1 to rotate about its axis. The sewage is filtered through the mesh sidewalls of the filter barrel 1. The clean water passes through the sidewalls into the sedimentation tank 4, while impurities, sludge, and particulate matter in the sewage are blocked by the mesh sidewalls of the filter barrel 1 and retained inside the filter barrel 1.

[0032] As filter drum 1 rotates, impurities, sludge, and particulate matter gradually adhere to the inner wall of filter drum 1 due to centrifugal force and friction, and move with filter drum 1. When filter drum 1 rotates to the point where the impurities, sludge, and particulate matter move directly above discharge mechanism 3, these solid materials break away from the inner wall under the action of gravity and fall into discharge mechanism 3. Discharge mechanism 3 discharges these materials out of the device, achieving automatic removal of impurities and sludge.

[0033] Through this repetitive treatment process, the device effectively separates and removes impurities, sludge, and particulate matter from wastewater, maintaining efficient operation of the filtration system. The filtered, clean wastewater flows through the sidewalls of filter barrel 1 into sedimentation tank 4, completing the entire treatment process. This design not only improves the automation level of wastewater treatment and reduces manual intervention, but also avoids system blockage and downtime caused by impurity accumulation.

[0034] The discharge mechanism 3 is designed to efficiently discharge impurities, sludge and particulate matter collected in the filter barrel 1. The discharge mechanism 3 includes components such as a trough body 31, a conveying pipe 32, a first motor 33, a spiral conveying blade 34 and a rotating shaft 35. The trough body 31 is fixedly connected to the upper end of the conveying pipe 32 and is connected to the interior of the conveying pipe 32 to ensure that impurities, sludge and particulate matter can smoothly enter the conveying pipe 32 from the trough body 31. One end of the conveying pipe 32 extends into the interior of the filter barrel 1 and is connected to the filter barrel 1 through a rotating connector, so that it can remain stable when the filter barrel rotates. The other end of the conveying pipe 32 is fixed to the second support frame 12 to ensure the stability of the overall structure.

[0035] A rotating shaft 35 is mounted inside the delivery pipe 32 and is free to rotate. One end of the shaft 35 extends out of the delivery pipe 32 and is connected to the output of the first motor 33, which provides power to drive the rotation of the shaft 35. Spiral conveying blades 34 are spirally arranged on the shaft 35 and distributed along its length. When the shaft 35 rotates, driven by the first motor 33, the spiral conveying blades 34 rotate synchronously, pushing impurities, sludge, and particulate matter inside the delivery pipe 32 along the pipe until they are delivered to the discharge port 321.

[0036] During actual use, when the filter barrel 1 rotates, impurities, sludge, and particulate matter in the sewage gradually gather on the inner wall of the filter barrel 1 due to centrifugal force and friction. When these solid materials move to the top of the tank body 31, they will automatically detach from the inner wall of the filter barrel 1 and fall into the tank body 31 under the action of gravity. Subsequently, the impurities, sludge, and particulate matter will enter the conveying pipe 32 through the tank body 31. At this time, the first motor 33 starts, driving the rotating shaft 35 to rotate. The spiral conveying blades 34 on the rotating shaft 35 push the impurities, sludge, and particulate matter along the conveying pipe 32 to the discharge port 321, and finally discharge them through the discharge port 321.

[0037] This design utilizes an automated drainage mechanism to efficiently remove impurities, sludge, and particulate matter trapped during the filtration process, reducing the need for manual intervention and maintenance and ensuring continuous, efficient operation of the wastewater treatment system. Furthermore, the action of the spiral conveyor blades 34 ensures uniform transport of solid matter, preventing blockages or accumulation, further improving system reliability and efficiency.

[0038] Specifically, since sewage also contains sludge, impurities and particulate matter may adhere to the inner wall of the filter barrel 1 and will not fall off. Therefore, a scraper 311 is provided on the trough body 31 of this embodiment. The scraper 311 is used to scrape off the attachments on the inner wall of the filter barrel 1. The side wall of the trough body 31 is inclined. The side wall of the trough body 31 is designed to be inclined to guide impurities, sludge and particulate matter.

[0039] Specifically, the drive mechanism 5 includes a ring gear 51, a gear 52, and a second motor 53. The ring gear 51 is fixedly connected to the filter barrel 1, and the gear 52 is connected to the output end of the second motor 53. The gear 52 meshes with the ring gear 51, and the second motor 53 is connected to the sedimentation tank 4. When the second motor 53 is started, the output end of the second motor 53 drives the gear 52 to rotate, which in turn drives the ring gear 51 to rotate. The rotation of the ring gear 51 drives the filter barrel 1 to rotate, thereby driving the filter barrel 1.

[0040] The present invention also includes a conveying mechanism 7 disposed between the sedimentation tank 4 and the aeration tank 6, for conveying clean water from the sedimentation tank 4 to the aeration tank 6 for further treatment. The conveying mechanism 7 includes a pump 71, a pumping pipe 72, a drain pipe 73, and a floating block 74. The pump 71 is used to provide water conveying power, and its input end is connected to the sedimentation tank 4 through the pumping pipe 72. To ensure that the pumping pipe 72 can be flexibly adjusted according to changes in the water level, the end of the pumping pipe 72 away from the pump 71 is connected to the floating block 74. The floating block 74 keeps the pumping pipe 72 near the water surface at all times, ensuring pumping efficiency. The end of the pumping pipe 72 away from the pump 71 passes through the floating block 74.

[0041] The output end of pump 71 is connected to aeration tank 6 via drain pipe 73, which extends into aeration tank 6 and is used to transport water pumped from sedimentation tank 4 to aeration tank 6. When pump 71 is started, water in sedimentation tank 4 is drawn into pump 71 through pump pipe 72 and then discharged into aeration tank 6 through drain pipe 73, providing a sufficient water source for the aeration process.

[0042] This conveying mechanism 7 effectively transfers filtered clean water from the sedimentation tank 4 to the aeration tank 6, ensuring the continuity of the sewage treatment process. The design of the floating block 74 ensures that the pumping pipe 72 automatically adjusts with the water level, preventing the pipe from sucking in excessive sediment and maintaining water flow stability and conveying efficiency. Furthermore, the rational layout of the pump 71 and conveying pipeline ensures rapid water delivery and efficient aeration treatment.

[0043] The aeration tank 6 is provided with an aeration device 8 for aerating the sewage to increase the dissolved oxygen content in the water, promote microbial activity, and accelerate the decomposition of organic matter. The aeration device 8 includes a fan 81 and an aeration pipe 82. The fan 81 is installed outside the aeration tank 6 and is responsible for transporting air into the aeration pipe 82. One end of the aeration pipe 82 is connected to the fan 81, and the other end extends into the interior of the aeration tank 6. The aeration pipe 82 includes multiple branch pipes 821, which are distributed at the bottom or middle of the aeration tank 6 to ensure that the air is evenly distributed throughout the tank.

[0044] The outer surface of branch pipe 821 is evenly distributed with multiple air holes 822. The size and distribution of air holes 822 are designed to ensure that air is discharged from branch pipe 821 in the form of fine bubbles. When fan 81 is started, air passes through fan 81 into aeration pipe 82 and then into branch pipe 821. The air is then discharged through air holes 822 in branch pipe 821, forming a large number of fine bubbles. These bubbles fully contact the wastewater, significantly increasing the oxygen concentration in the water. This effectively promotes the oxidation of organic matter and microbial activity in the wastewater, completing the aeration treatment process.

[0045] By setting the aeration device 8, a uniform and sufficient aeration effect is achieved in the aeration tank 6. The tiny bubbles have a larger specific surface area, so that the oxygen in the air can be quickly dissolved into the sewage, thereby improving the aeration efficiency.

[0046] Specifically, the sedimentation tank 4 includes a tank body 41 and a water collection tank 42. The first support frame 11 and the second support frame 12 are respectively connected to the water collection tank 42. The top wall of the tank body 41 is provided with a notch 411. The filtered water enters the sedimentation tank 4, where it can be settled and treated to improve the sewage treatment effect.

[0047] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
