Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment sedimentation tank with a reversible filter plate. Background Technology

[0002] In wastewater treatment, the sedimentation process is divided into primary sedimentation and secondary sedimentation. Primary sedimentation is generally a pretreatment for particles and suspended solids with a larger specific gravity. Secondary sedimentation is generally carried out after the aeration process to separate sludge from the effluent, and then further treats it according to different discharge requirements and subsequent treatment processes.

[0003] Existing wastewater treatment sedimentation tanks often use fixed filter plates. When a large amount of sludge and impurities accumulate on the filter plate surface, cleaning becomes extremely inconvenient. Operators often need to enter the sedimentation tank or use tools to reach inside and wipe and rinse the plates. This not only limits the operating space and makes cleaning difficult but also consumes a significant amount of time, affecting the continuity of wastewater treatment. Therefore, we propose a wastewater treatment sedimentation tank with a reversible filter plate. Summary of the Invention

[0004] The purpose of this utility model is to provide a wastewater treatment sedimentation tank with a reversible filter plate, in order to solve the problem mentioned in the background art that most of the filter plates in the existing wastewater treatment sedimentation tanks are fixed installation structures. When a large amount of sludge and impurities are trapped on the surface of the filter plate, it is very inconvenient to clean. Operators often need to enter the sedimentation tank or use tools to go deep into the tank to wipe and rinse. Not only is the operating space limited and the cleaning difficult, but it also takes up a lot of time and affects the continuity of wastewater treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment sedimentation tank with a reversible filter plate, comprising: a sedimentation tank body, a water tank inside the sedimentation tank body, a water flow hole through the side surface of the water tank, a support plate fixedly connected to the outer surface of the sedimentation tank body, a filter assembly on the upper surface of the support plate, an installation assembly fixedly connected to the outer surface of the filter assembly, and the filter assembly can be disassembled and cleaned through the installation assembly.

[0006] The filter assembly includes a drive motor, which is fixedly connected to the upper surface of the support plate. A rotating rod is fixedly connected to the output end of the drive motor, and a positioning ring is movably connected to the outer surface of the rotating rod. The positioning ring is fixedly connected to the outer surface of the sedimentation tank body.

[0007] The rotating rod is fixedly connected to a filter plate at the end away from the drive motor. Filter holes are opened through the front and rear surfaces of the filter plate. A filter plate is movably connected inside the filter plate. Fine filter holes are opened on one side of the filter plate, coarse filter holes are opened on the other side of the filter plate, and a dirt storage tank is opened through the middle of the filter plate.

[0008] The installation components include a fixing plate, which is fixedly connected to the outer surface of the filter plate on the side facing the filter plate. The fixing plates are arranged in four groups and fixedly connected at the four corners of the filter plate.

[0009] The fixed plate has a fixed bolt movably connected to its outer surface. The fixed plate is triangular in shape. The bottom of the fixed plate is movably connected to a mounting plate. The outer surface of the mounting plate is fixedly connected to a limit plate. A spring post is fixedly connected to the side of the limit plate away from the mounting plate. The side of the spring post away from the limit plate is fixedly connected to the inner wall of the fixed plate. The mounting plate is movably connected to the inner and outer ends of the fixed plate.

[0010] The sedimentation tank consists of multiple interconnected main bodies, with wastewater flowing through these main bodies via water circulation holes.

[0011] This utility model has at least the following beneficial effects: 1. In use, this utility model, through its set filter components, a drive motor and a rotating rod are fixedly connected. Under the rotational guidance of the positioning ring, it can stably drive the filter plate and the internal filter plate to rotate synchronously. The fine pores on one side of the filter plate can accurately filter small impurities, while the coarse pores on the other side can efficiently trap larger particles. The filter surface can be flexibly selected according to the nature of the wastewater, improving filtration adaptability. During rotation, impurities are thrown into the sludge collection tank under the action of centrifugal force and water flow, reducing the possibility of impurities clogging the filter pores. When cleaning is required, the drive motor can continue to drive the rotating rod, causing the filter plate and filter plate to flip from the water tank to the outside of the sedimentation tank body. Operators can directly clean the sludge collection tank without having to go deep into the sedimentation tank body, greatly improving the convenience and efficiency of cleaning.

[0012] 2. In use, this utility model employs an installation assembly where four sets of triangular fixing plates are respectively fixed at the four corners of the filter plate. These plates are connected to the mounting plate via fixing bolts. Combined with the limiting plate connected to the spring posts on the inner wall of the fixing plate, a continuous pre-tightening force is applied to the mounting plate, ensuring the filter plate is securely installed within the filter plate and preventing loosening or displacement during filter rotation. When the filter plate needs to be disassembled for thorough cleaning or replacement, simply push the mounting plate inwards, causing the compressed spring posts to displace into the fixing plate, quickly releasing the limiting force on the filter plate. This operation is simple and effortless. During reinstallation, the elastic restoring force of the spring posts quickly and securely limits the mounting plate's position on the filter plate, significantly simplifying the disassembly and assembly process and reducing maintenance difficulty.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a sewage treatment sedimentation tank with a reversible filter plate, comprising: a sedimentation tank body 1, a water tank 2 inside the sedimentation tank body 1, a water flow hole 3 through the side surface of the water tank 2, a support plate 4 fixedly connected to the outer surface of the sedimentation tank body 1, a filter assembly 5 on the upper surface of the support plate 4, an installation assembly 6 fixedly connected to the outer surface of the filter assembly 5, and the filter assembly 5 can be disassembled and cleaned through the installation assembly 6.

[0017] In use, the filter assembly 5, drive motor 51, and rotating rod 52 are fixedly connected. Under the rotational guidance of positioning ring 53, the filter plate 54 and the internal filter plate 56 can be stably driven to rotate synchronously. The fine filter holes 57 on one side of the filter plate 56 can accurately filter small impurities, while the coarse filter holes 58 on the other side can efficiently trap larger particles. The filter surface can be flexibly selected according to the nature of the wastewater, improving the filtration adaptability. During rotation, impurities are thrown into the sludge storage tank 59 for centralized collection under the action of centrifugal force and water flow, reducing the possibility of impurities clogging the filter holes. When cleaning is required, drive motor 51 can continue to drive rotating rod 52, causing filter plate 54 and filter plate 56 to flip from water tank 2 to the outside of sedimentation tank body 1. Operators can directly clean the sludge storage tank 59 without having to go deep into the sedimentation tank body, greatly improving the convenience and efficiency of cleaning.

[0018] The filter assembly 5 includes a drive motor 51, which is fixedly connected to the upper surface of the support plate 4. A rotating rod 52 is fixedly connected to the output end of the drive motor 51. A positioning ring 53 is movably connected to the outer surface of the rotating rod 52 and is fixedly connected to the outer surface of the sedimentation tank body 1.

[0019] A filter plate 54 is fixedly connected to the end of the rotating rod 52 away from the drive motor 51. Filter holes 55 are opened through the front and rear surfaces of the filter plate 54. A filter plate 56 is movably connected inside the filter plate 54. Fine filter holes 57 are opened on one side of the filter plate 56, and coarse filter holes 58 are opened on the other side of the filter plate 56. A dirt storage tank 59 is opened through the middle of the filter plate 56.

[0020] The mounting assembly 6 includes a fixing plate 61, which is fixedly connected to the outer surface of the filter plate 54 on the side facing the filter plate 56. The fixing plates 61 are fixedly connected in four groups at the four corners of the filter plate 54.

[0021] A fixing bolt 62 is movably connected to the outer surface of the fixing plate 61. The fixing plate 61 is triangular in shape. A mounting plate 63 is movably connected to the bottom of the fixing plate 61. A limiting plate 64 is fixedly connected to the outer surface of the mounting plate 63. A spring post 65 is fixedly connected to the side of the limiting plate 64 away from the mounting plate 63. The side of the spring post 65 away from the limiting plate 64 is fixedly connected to the inner wall of the fixing plate 61. The mounting plate 63 is movably connected to the inner and outer ends of the fixing plate 61.

[0022] The sedimentation tank body 1 consists of multiple interconnected groups, and the sewage flows through the multiple groups of sedimentation tank body 1 via the water flow holes 3.

[0023] In operation, in its initial state, the sedimentation tank body 1 serves as the core carrier for wastewater treatment. The internal water tank 2 stores the wastewater to be treated, and the flow holes 3 on the side surface allow multiple interconnected sedimentation tank bodies 1 to form a continuous wastewater flow channel, achieving staged filtration. The support plate 4 on the outer surface of the sedimentation tank body 1 provides stable support for the filter assembly 5. The filter assembly 5 is connected to the filter plate 54 via the mounting assembly 6, ensuring the stability of the filtration process and facilitating subsequent disassembly and cleaning.

[0024] In the filter assembly 5, the drive motor 51 is fixed to the upper surface of the support plate 4, and its output end is fixedly connected to the rotating rod 52. The rotating rod 52 passes through the positioning ring 53 fixed to the outer surface of the sedimentation tank body 1. The positioning ring 53 guides the rotation of the rotating rod 52 to ensure that it does not deviate during rotation. The filter plate 54 fixed at the end of the rotating rod 52 is located in the water tank 2. The filter holes 55 on the filter plate 54 provide a flow path for the filtered sewage. The filter plate 56, which is movably connected inside the filter plate 54, is the core component of the filter. The fine filter holes 57 on one side can filter small impurities, and the coarse filter holes 58 on the other side can trap larger particles. The sludge storage tank 59 in the middle is used to collect the impurities trapped during the filtration process.

[0025] The four sets of triangular fixing plates 61 of the mounting assembly 6 are respectively fixed at the four corners of the filter plate 54 and connected to the mounting plate 63 by fixing bolts 62, firmly fixing the filter plate 56 inside the filter plate 54. The spring post 65 on the inner wall of the fixing plate 61 is connected to the limiting plate 64. The limiting plate 64 is in contact with the mounting plate 63. During installation, the elastic force of the spring post 65 provides a pre-tightening force, which enhances the installation stability of the filter plate 56. At the same time, this elastic structure can assist the separation of the mounting plate 63 from the fixing plate 61 during disassembly, realizing quick disassembly.

[0026] When the device is running, wastewater enters the water tank 2 of the sedimentation tank body 1. The drive motor 51 starts, and the rotating rod 52 drives the filter plate 54 and the internal filter plate 56 to rotate synchronously. During the rotation, the wastewater flows through the filter plate 56. Depending on the treatment requirements, the fine filter holes 57 or coarse filter holes 58 are directed towards the water flow direction: the coarse filter holes 58 intercept larger particulate impurities, and the fine filter holes 57 filter small suspended particles. The impurities are thrown into the sludge storage tank 59 for temporary storage under the action of centrifugal force and water flow. The filtered wastewater flows out through the filter holes 55 or enters the next set of sedimentation tank bodies 1 for further treatment through the flow water holes 3.

[0027] When the filter assembly 5 needs cleaning, the drive motor 51 drives the rotating rod 52 to continue rotating, causing the filter plate 54 and filter plate 56 to flip from the water tank 2 to the outside of the sedimentation tank body 1, making it convenient for operators to directly clean the impurities in the sludge storage tank 59. If a thorough cleaning or replacement of the filter plate 56 is required, simply push the mounting plate 63 inward, causing the mounting plate 63 to compress and shift into the interior of the fixing plate 61, releasing the restriction on the filter plate 56, at which point the filter plate 56 can be quickly removed. After cleaning or replacement, the filter plate 56 is placed back into the filter plate 54, re-fixed by the mounting assembly 6, and then driven by the drive motor 51 to flip it back into the water tank 2, restoring the device to its filtration state.

[0028] The main body 1 of multiple sedimentation tanks achieves step-by-step deep treatment of sewage through the series design of the water flow holes 3; while the combination of the rotary filtration and overturning cleaning function of the filter component 5 and the quick-release limiting function of the installation component 6 not only improves the filtration efficiency but also simplifies the maintenance process and ensures the long-term stable operation of the device.
