Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an anti-clogging mechanism for filtration devices in wastewater treatment. Background Technology

[0002] With the accelerating pace of industrialization, wastewater discharge is increasing daily, making wastewater treatment systems a crucial link in ensuring the recycling of water resources and attracting widespread attention. In wastewater treatment equipment, filtration devices are used to initially separate suspended solids and impurities from wastewater, and their operational efficiency directly affects the efficiency of subsequent treatment processes.

[0003] However, traditional filtration devices are prone to clogging of the filter plate surface with impurities during long-term operation, leading to decreased filtration efficiency and even requiring frequent shutdowns for maintenance. This severely affects the continuity and stability of the treatment system. To address these issues, some existing technologies, such as Chinese patent document CN213790294U, propose an anti-clogging mechanism for domestic sewage treatment devices. This mechanism involves a primary motor, a lead screw, a gear, a secondary motor, and a telescopic rod. After prolonged use, when excessive impurities remain on the filter screen, the secondary motor drives the gear to rotate, causing the filter screen to move upwards. Simultaneously, the primary motor drives the lead screw to rotate, moving the fixed rod. When impurities come into contact with the telescopic rod, the spring is compressed, allowing the telescopic rod to more effectively move the impurities to the discharge outlet, preventing impurity accumulation and improving sewage treatment efficiency. However, this method suffers from drawbacks such as complex structure, unstable cleaning effect, and water waste, making it difficult to meet the demands for high efficiency, low energy consumption, and automation in practical applications. Therefore, this invention proposes an anti-clogging mechanism for filtration devices in sewage treatment to meet the need for improved automatic cleaning of the filter plate surface. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an anti-clogging mechanism for filtration devices in sewage treatment, so as to solve the problem of unstable cleaning effect of filter plates in the prior art.

[0005] To achieve the above objectives, this utility model provides an anti-clogging mechanism for a filtration device in wastewater treatment, including a support frame, a filter box body mounted on the support frame, a collection trough at the bottom of the filter box body, multiple filter plate bodies mounted inside the filter box body, and a cleaning component mounted on each filter plate body; the cleaning component is used to clean impurities adhering to the surface of the filter plate body.

[0006] Preferably, the cleaning assembly includes a first sliding groove at the center of the filter plate body, a cleaning plate is disposed in the first sliding groove, a limiting block is disposed at the center of the cleaning plate, the limiting block is slidably disposed in the first sliding groove, the bottom of the cleaning plate is a triangle tilted to one side, and one side of the bottom of the cleaning plate is in contact with the surface of the filter plate body.

[0007] Preferably, a set of connecting rods is provided at both ends of the filter plate body, a rotating belt is sleeved on the connecting rods, a set of first driving plates is symmetrically arranged on the rotating belt, a second driving plate is arranged between the first driving plates, and the length of the second driving plate is less than the length of the first driving plate.

[0008] Preferably, a set of second sliding grooves is provided at one end of the first drive plate, and a sliding rod is slidably disposed in the second sliding groove. One end of the sliding rod is connected to a trigger plate, which is an arc-shaped structure bent to one side, and one end of the trigger plate is in contact with one end of the cleaning plate.

[0009] Preferably, an extension plate is provided on one side of the trigger plate, a support plate is provided at one bottom end of the first drive plate, a guide rod is provided at one end of the support plate, the guide rod is a telescopic structure, one end of the guide rod is in contact with the extension plate, a return spring is sleeved on the guide rod, one end of the return spring is located on one side of the extension plate, and the other end of the return spring is located on one side of the support plate.

[0010] Preferably, an extension block is provided on one side of the bottom of the first sliding groove, a telescopic rod is provided on the extension block, a contact head is provided on the top of the telescopic rod, the contact head contacts the limiting block, and a buffer spring is sleeved on the telescopic rod, one end of the buffer spring contacts the top of the extension block, and the other end of the buffer spring contacts the contact head.

[0011] Preferably, the weight of the cleaning plate is greater than the buoyancy of the cleaning plate when impacted by the water flow.

[0012] The beneficial effects of this utility model are:

[0013] 1. The entire structure is supported by a support frame, on which the filter box body is mounted to hold and filter wastewater. A collection trough is located at the bottom of the filter box body to collect the filtered wastewater or impurities. Multiple filter plates are installed inside the filter box body. Wastewater undergoes solid-liquid separation as it passes through the filter plates. To prevent clogging caused by impurities on the filter plate surface, a cleaning component is installed. This component mechanically removes impurities from the filter plate surface, ensuring filtration efficiency and long-term operational stability. By using the cleaning component to clean impurities adhering to the filter plate surface in real time, clogging caused by dirt accumulation is effectively prevented, improving filtration efficiency and automation levels, extending equipment operating cycles, reducing maintenance frequency, and enhancing overall operational stability and reliability.

[0014] 2. During the filtration of wastewater through the filter plate body, the first and second drive plates, driven by the water flow, rotate the belt around the connecting rod. As the first drive plate rises, it drives the connected trigger plate to rise as well. The trigger plate is an arc-shaped structure bent to one side. One side of the trigger plate contacts the cleaning plate located in the first sliding groove, which can push the cleaning plate upward and slide it, causing the cleaning plate to move relative to the surface of the filter plate body, forming an automatic cleaning mechanism. This effectively solves the clogging problem caused by the accumulation of impurities on the surface of the filter plate body, achieving the purpose of cleaning the attached impurities. When the trigger plate rises to the top, the sliding rod moves in the second sliding groove, causing the trigger plate to gradually disengage from the cleaning plate. The bottom of the cleaning plate is a triangle tilted to one side, which can make more full contact with the filter surface and improve cleaning efficiency. After the cleaning action is completed, the cleaning plate falls back to the surface of the filter plate body by its own gravity and automatically resets. No additional drive system is required, simplifying the structure and reducing energy consumption, thus completing one cleaning cycle. At the same time, the cooperation of the reset spring and the guide rod ensures that the trigger plate resets in time, improving the operational reliability and service life of the device, making it suitable for wastewater filtration environments with long-term stable operation.

[0015] 3. By installing a telescopic rod and a buffer spring below the first sliding groove, a flexible buffer force is provided during the movement of the cleaning plate, preventing severe impacts or sliding resistance, reducing rigid collisions between the cleaning plate and the limiting block, avoiding wear or deformation of parts due to impact, and extending the service life of the device. At the same time, the buffer spring provides a gentle counter-pushing force during the return process after cleaning, which helps the cleaning plate to return to its original position smoothly, improving the smoothness of operation and the stability of the overall structure, and effectively enhancing the working reliability of the sewage treatment system.

[0026] The entire structure is supported by a support frame 1, on which a filter box body 2 is mounted for containing and filtering wastewater. A collection tank 3 is located at the bottom of the filter box body 2 for collecting filtered wastewater or impurity liquid. Multiple filter plate bodies 4 are installed inside the filter box body 2. Wastewater undergoes solid-liquid separation as it passes through the filter plate bodies 4. To prevent clogging caused by impurity accumulation on the surface of the filter plate bodies 4, a cleaning component is installed on their surface. This cleaning component can mechanically remove impurities from the surface of the filter plate bodies 4, thereby ensuring its filtration efficiency and long-term operational stability. By setting up a cleaning component to clean the impurities attached to the surface of the filter plate bodies 4 in real time, the filter plates are effectively prevented from clogging due to dirt accumulation, improving filtration efficiency and automation level, extending equipment operating cycle, reducing maintenance frequency, and improving overall operational stability and reliability.

[0027] like Figures 2-4As shown, the cleaning assembly includes a first sliding groove 11 opened at the center of the filter plate body 4, a cleaning plate 5 disposed in the first sliding groove 11, the weight of the cleaning plate 5 being greater than the buoyancy of the cleaning plate 5 under the impact of water flow; a limiting block 6 disposed at the center of the cleaning plate 5, the limiting block 6 being slidably disposed in the first sliding groove 11, the bottom of the cleaning plate 5 being a triangle tilted to one side, one side of the bottom of the cleaning plate 5 contacting the surface of the filter plate body 4; a set of connecting rods 7 are respectively disposed at both ends of the filter plate body 4, a rotating belt 8 is sleeved on the connecting rods 7, a set of first driving plates 9 are symmetrically disposed on the rotating belt 8, a second driving plate 10 is disposed between the first driving plates 9, the second driving plate 10 is located at the center of the set of first driving plates 9, and the length of the second driving plate 10 is smaller than that of the first driving plates 9. The length of the first drive plate 9 is as follows: A set of second sliding grooves 12 is opened at one end of the first drive plate 9, and a sliding rod 13 is slidably arranged in the second sliding grooves 12. One end of the sliding rod 13 is connected to a trigger plate 14. The trigger plate 14 is an arc-shaped structure that bends to one side. One end of the trigger plate 14 is in contact with one end of the cleaning plate 5. An extension plate 15 is provided on one side of the trigger plate 14. A support plate 16 is provided at one bottom end of the first drive plate 9. A guide rod 17 is provided at one end of the support plate 16. The guide rod 17 is a telescopic structure.

[0028] During the filtration of wastewater through the filter plate body 4, the first drive plate 9 and the second drive plate 10, under the impact of the water flow, drive the rotating belt 8 to rotate around the connecting rod 7. As the first drive plate 9 rises, it drives the trigger plate 14 connected to it to rise. The trigger plate 14 has an arc-shaped structure bent to one side. One side of the trigger plate 14 contacts the cleaning plate 5 located in the first sliding groove 11, which can push the cleaning plate 5 to slide upward, so that the cleaning plate 5 moves relative to the surface of the filter plate body 4, forming an automatic cleaning mechanism.

When the trigger plate 14... After rising to the top, the sliding rod 13 moves within the second sliding groove 12, causing the trigger plate 14 to gradually disengage from the cleaning plate 5. The bottom of the cleaning plate 5 is a triangle tilted to one side, which can make fuller contact with the filter surface and improve cleaning efficiency. After the cleaning action is completed, the cleaning plate 5 falls back onto the surface of the filter plate body 4 under its own gravity and automatically resets. No additional drive system is required, which simplifies the structure and reduces energy consumption, thus completing one cleaning cycle. At the same time, the cooperation of the reset spring 18 and the guide rod 17 ensures that the trigger plate 14 resets in time, improving the operational reliability and service life of the device, and making it suitable for sewage filtration environments with long-term stable operation.

At the same time, the buffer spring 22 provides a gentle counter-pushing force during the return process after cleaning, which helps the cleaning plate 5 to return to its original position smoothly, improving the smoothness of operation and the stability of the overall structure, and effectively improving the working reliability of the sewage treatment system.
