Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage interception technology, and in particular to an interception device for sewage treatment in a sewage treatment pond. Background Technology
[0002] Human production and daily life activities generate a huge amount of wastewater. If this wastewater is discharged directly without proper treatment, it will cause serious pollution to the natural water bodies, soil and air, threatening human health and ecological balance. Therefore, it is crucial to carry out comprehensive and efficient treatment before discharging wastewater, which has become a key link in environmental protection work.
[0003] In wastewater treatment, interception devices are an indispensable part, bearing the crucial responsibility of removing various impurities from the wastewater to prevent damage to subsequent treatment equipment and ensure the smooth operation of the treatment process. However, currently common wastewater treatment pond interception devices have significant shortcomings.
[0004] Regarding the barrier netting, the existing barrier netting design does not fully consider the ease of cleaning and maintenance after long-term use. As sewage continues to flow through, a large number of small debris, such as fine fibers, sand, and algae, will gradually become embedded in the gaps of the barrier netting. Due to the lack of an effective cleaning mechanism, manual cleaning is labor-intensive and time-consuming, which makes the mesh blockage more and more serious. This not only significantly reduces the water flow capacity of the barrier netting, causing sewage to stagnate in the pool and resulting in low treatment efficiency, but may also cause poor water flow, resulting in local water pressure imbalance, which poses a potential threat to the structural safety of the sewage treatment pool.
[0005] Furthermore, a significant amount of heavy material often accumulates at the bottom of the pool near the interception device. Over a long period, this material not only piles up at the bottom of the pool, occupying a large amount of space and affecting the effective treatment volume of the wastewater, but also mixes with sludge and other impurities at the bottom of the pool, forming a dense accumulation layer. Traditional cleaning methods, such as manual retrieval, consume a lot of manpower and are inefficient because the accumulation of heavy material near the bottom of the pool near the interception device is relatively fast. It is easy for the bottom of the pool near the interception device to need cleaning while other areas of the treatment pool have not yet reached the level of cleaning. If cleaning is carried out at this time, it will further waste a lot of manpower. If it is not cleaned, it will cause the accumulation layer to form.
[0006] In conclusion, it is urgent to develop a new type of interception device for sewage treatment ponds. Utility Model Content

[0042] This utility model proposes an interception device for sewage treatment in a sewage treatment pond. By setting up a dredging mechanism and a collection mechanism, the interception device makes it easier and more efficient to clean the gaps of the screen 3, and can collect the separated debris and the heavy objects at the bottom of the device, thus avoiding the problem of heavy objects affecting the sewage treatment efficiency.
[0043] Example 1
[0044] In this embodiment, the structure of an interception device for sewage treatment in a sewage treatment pond is as follows: Figures 1 to 5 As shown, where Figure 4 Only a portion of the interception device is shown; the main focus is on the parts relevant to this invention.
[0045] The interception device of this utility model includes a waterway 1, a pair of bases 2 are fixedly installed at the top of the waterway 1, and a grid 3 is installed between the bases 2. In this embodiment, the grid 3 is preferred as the interception body because the vertical strip-shaped holes of the grid 3 have a larger size and more regular shape than the mesh of the traditional interception net. It can more effectively intercept long strips and blocky debris commonly found in sewage, such as branches, plastic pieces, and fiber bundles, and is not easy to clog and easy to clean. In addition, the horizontal height of the top of the grid 3 is higher than the highest water level in the base 2.
[0046] like Figures 1 to 5As shown, a sewage treatment interception device for a sewage treatment pond includes a dredging mechanism and a collection mechanism. The dredging mechanism includes a debris removal component, which is slidably disposed on one side of a screen 3 to separate debris and garbage attached to the screen 3. The dredging mechanism also includes a lifting component, which controls the up-and-down movement of the debris removal component. The lifting component is also equipped with a counterweight ring 13. The collection mechanism includes a drive component and an isolation component. The lifting component is connected to the isolation component through the drive component. The drive component can drive the isolation component to open or close. The isolation component is used to collect and store the debris separated from the debris by the debris removal component from the bottom of the interception device. In the sewage treatment process, sewage continuously flows through the interception net in the existing interception device. A large number of small debris, such as fine fibers, sand particles, and algae, gradually become embedded in the gaps of the interception net. Due to the lack of effective cleaning methods, manual cleaning faces problems such as high labor intensity and long cleaning cycles, which makes the mesh blockage increasingly worse, significantly weakening the water passage capacity of the interception net, causing the sewage to stay in the pond for a longer time, and reducing the sewage treatment efficiency. Furthermore, near the bottom of the pool where the interception device is located, a large amount of heavy objects often accumulate, occupying a significant amount of space and reducing the effective treatment volume of the wastewater. These objects also mix with sludge and other impurities at the bottom, forming a dense accumulation layer. Because the accumulation of heavy objects near the interception device is rapid, this area often needs cleaning while other parts of the treatment pool have not yet reached the cleaning standard. Cleaning in this situation results in a significant waste of human resources; if not cleaned, the accumulation layer will continue to grow, further affecting the wastewater treatment effect. However, with the dredging and collection mechanisms described in this embodiment, the interception device eliminates the need for manual cleaning of the gaps in the grille 3, separating debris from the gaps. This makes cleaning the gaps in the grille 3 more convenient and efficient, and allows for the collection of the separated debris along with the heavy objects at the bottom of the device, preventing the heavy objects from affecting wastewater treatment efficiency.
[0047] The impurity removal component includes a first separating rod 4 disposed on one side of the grid 3, such as Figures 1 to 3As shown, first separation blocks 5 are evenly arranged on one side of the first separating rod 4. The first separation blocks 5 are all slidably installed in the gaps between the grids 3. Connecting blocks 6 are symmetrically fixed to the top of the first separating rod 4, and second separating rods 7 are fixedly installed to the top of the connecting blocks 6. Second separation blocks 8 are evenly arranged on one side of the second separating rod 7, and the second separation blocks 8 are all slidably installed in the gaps between the grids 3. This design allows the first separating blocks 5 and the second separating blocks 8 to perform two cleaning operations when the impurity removal component cleans the gaps between the grids 3. The distance between the top and bottom of the first separating block 5 is greater than the distance between the top and bottom of the second separating block 8, while the distance between the two longitudinal ends of the second separating block 8 is greater than the distance between the two longitudinal ends of the first separating block 5. This allows the first separating blocks 5 to perform a first coarse treatment on larger impurities, while the first separating rod 4 cleans the side of the grid 3 closest to the first separating rod 4. Then, the second separating blocks 8 perform a second fine treatment on smaller impurities, while the second separating rod 7 cleans the side of the grid 3 closest to the first separating rod 4, thereby improving the cleaning effect of the impurity removal component.
[0048] Furthermore, each of the second separating blocks 8 is symmetrically fixed with a cutting block 9 at its bottom. The side of the cutting block 9 closest to the grid 3 is set as a straight part that fits the grid 3, and the side of the cutting block 9 away from the grid 3 is set as an inclined part. By designing the cutting block 9, it is possible to remove tough debris such as ropes and weeds that are wrapped around the grid 3 and are difficult to remove by squeezing alone. At this time, the cutting block 9 can cut these tough debris, thereby effectively separating the tough debris wrapped around the grid 3 and further improving the debris removal effect of the debris removal component.
[0049] In this embodiment, as Figure 2 and Figure 3As shown, the lifting assembly includes lifting rods 10 disposed at both ends of the first separating rod 4. The lifting rods 10 pass through the first separating rod 4 and extend to both sides of the first separating rod 4. Both ends of the first separating rod 4 and the lifting rods 10 are slidably mounted on the inner wall of the base 2. A connecting ring 11 is fixedly installed at the top of the lifting rod 10. A winding device 12 is provided on the inner wall of the waterway 1. The winding device 12 is connected to an external power system (the power system is not shown in the diagram; in this embodiment, a YE2 three-phase asynchronous motor is preferred. Since it is a mature existing technology, its internal structure and working principle will not be described in detail). The connecting ring 11 and the winding device 12 can be connected by a wire rope or anchor chain (not shown in the diagram). The outer wall of the lifting rod 10 is equipped with a counterweight ring 13. When it is necessary to clean the grid 3, the operator can start the winding device 12, which will rotate and release the rope, causing the cleaning component to move downward under the action of gravity, thereby separating the debris in the gaps of the grid 3. After cleaning is completed, the operator can start the winding device 12 in reverse, which will rotate and retract the rope, causing the winding device 12 to drive the first separating rod 4 to move through the rope, connecting ring 11 and lifting rod 10, thereby driving the cleaning component to reset. This design can automate the cleaning operation, avoid the problems of high labor intensity and long cleaning cycle faced by manual cleaning, and save a lot of human resources.
[0050] In this embodiment, as Figure 2 and Figure 4As shown, the drive assembly includes a first drive block 14 disposed at the bottom of the lifting rod 10. The first drive blocks 14 are all slidably mounted on the inner wall of the slide groove 15, which is formed on the inner wall of the base 2. Guide bars 16 are fixedly mounted on the inner walls of the slide grooves 15, and the slide grooves 15 are slidably mounted on the outer walls of the guide bars 16. A second drive block 17 is slidably mounted on the end of the guide bar 16 away from the first drive block 14. The first drive block 14 and the second drive block 17 are connected by a connecting rod 18. An isolation component is provided on one side of the second drive block 17. This design allows the lifting rod 10 to move the first drive block 14 when the impurity removal assembly is performing impurity removal. The first drive block 14 then moves the second drive block 17 via the connecting rod 18. Furthermore, the isolation component includes a base plate 19 and a component disposed on one side of the second drive block 17. The isolation plate 20 and the base plate 19 are fixedly installed at the bottom end of the grid 3. The isolation plate 20 is slidably installed at the bottom end of the base plate 19. A sludge hopper 21 is provided at the bottom end of the isolation plate 20. Normally, the sludge hopper 21 is closed to avoid affecting the flow and treatment of sewage. When the interception device removes impurities, it can cooperate with the drive component to make the lifting rod 10 drive the second drive block 17 to move through the drive component. This causes the second drive block 17 to move the isolation plate 20 and open the sludge hopper 21. This allows the impurities separated by the impurity removal component in the gaps of the grid 3 to enter the sludge hopper 21, preventing the impurities from accumulating at the bottom of the interception device and mixing with the sludge and other impurities at the bottom of the tank over time to form a dense accumulation layer that occupies a large amount of space at the bottom of the tank, thus reducing the effective treatment volume of sewage.
[0051] Furthermore, in this embodiment, as Figure 2 As shown, a connecting plate 22 is symmetrically installed on one side of the isolation plate 20. A collecting plate 23 is fixedly installed on the end of the connecting plate 22 away from the isolation plate 20. The distance between the two sides of the connecting plate 22 is equal to the distance between the sludge hopper 21 near the collecting plate 23 and the grid 3. When the isolation plate 20 moves to open the sludge hopper 21, the isolation plate 20 drives the collecting plate 23 to move through the connecting plate 22, thereby bringing the heavy objects accumulated at the bottom of the interception device into the sludge hopper 21. This increases the effective treatment volume of the sewage, optimizes the sewage flow state, avoids blockage of the waterway 1, and ensures the sewage treatment system. For normal operation of the system, the collection plate 23 is configured as a curved arc. The collection plate 23 also includes a concave part and an convex part. The side closer to the connecting plate 22 is configured as the concave part, and the side farther away from the connecting plate 22 is configured as the convex part. This design can improve the collection efficiency through the concave part, making it easier for heavy objects to accumulate in the collection plate 23, increasing the effective volume of the collection plate 23, and also helping the heavy objects to remain stable during movement, preventing the heavy objects from moving out of the top of the collection plate 23. At the same time, the convex part can reduce the impact on the water flow during normal operation, thereby reducing the impact on the sewage treatment efficiency.
[0052] Example 2
[0053] As another implementation of this solution, such as Figures 6 to 9 As shown, in this embodiment, the grid 3 is set as a curved arc. This design allows the water flow to form a certain curved flow when passing through the grid 3, increasing the water flow area and guiding the water flow better, thus improving the cleaning effect. At the same time, it can increase the contact area between the grid 3 and the water flow, making it easier for impurities in the sewage to be intercepted on the grid 3. For some fine particles and fibrous materials, the interception effect is more significant, further improving the quality of sewage treatment. The curved arc grid 3 is often used in small and medium-sized sewage treatment plants and can effectively intercept floating and suspended solids in sewage.
[0054] Furthermore, to ensure the separation effect of the first separating rod 4 on the grille 3, in this embodiment, as follows: Figures 7 to 9 As shown, abutment blocks 24 are evenly slidably installed on one side of the first separating rod 4. The ends of the abutment blocks 24 away from the grille 3 are all slidably installed on the inner wall of the sealing shell 25. The sealing shell 25 is fixedly installed on the other side of the first separating rod 4. The abutment blocks 24 and the sealing shell 25 are connected by springs 26. With this design, when the impurity removal component is cleaning, the first separating rod 4 drives the abutment blocks 24 to move, so that the abutment blocks 24 can always abut against one side of the grille 3 under the push of the springs 26, thereby preventing the grille 3 from approaching the abutment blocks. The debris entangled on one side of the abutment block 24 is separated, which improves the debris removal effect of the debris removal component. In addition, limit blocks 27 are fixedly installed on both sides of the abutment block 24. The limit blocks 27 slide on the inner wall of the limit groove 28. The limit groove 28 is opened on the inner wall of the sealing shell 25 and the first separation rod 4. This design can limit the movement range of the abutment block 24, thereby avoiding the problem that the abutment block 24 moves out of the inner wall of the sealing shell 25 and the first separation rod 4 under the elastic action of the spring 26, and improving the stability and reliability of the interception device.
[0055] Working principle: When a large amount of debris adheres to and remains in the gaps of the grid 3, the operator can activate the winding device 12, causing it to rotate and release the rope. At this time, the lifting rod 10 moves downward under the gravity of the counterweight ring 13. The lifting rod 10 drives the first separating rod 4 to move, and the first separating rod 4 drives the first separating block 5 to move, causing the first separating block 5 to move along the gaps of the grid 3, thereby separating larger debris in the gaps of the grid 3. Simultaneously, the first separating rod 4 moves along the side of the grid 3 closest to the first separating rod 4, causing the first separating rod 4 to separate debris wrapped around the side of the grid 3 closest to the first separating rod 4. At the same time, the first separating rod 4 drives the connecting block 6 to move, and the connecting block 6 drives the second separating rod 7 to move, causing the second separating rod 7 to drive the second separating block 8 and the cutting block 9 to move. The cutting block 9 first contacts the debris in the gaps of the grid 3, thereby cutting off the high-toughness debris wrapped around the surface of the grid 3. Then the second... Separating rod 7 and second separating block 8 perform a second cleaning of the surface of grid 3. At the same time, lifting rod 10 drives first driving block 14 to move. First driving block 14 moves along guide bar 16, causing first driving block 14 to drive one end of connecting rod 18 to rotate. The other end of connecting rod 18 drives second driving block 17 to move along guide bar 16. Second driving block 17 drives isolation plate 20 to move. Isolation plate 20 moves to the bottom end of bottom plate 19, thereby opening sludge hopper 21. This allows debris separated from the surface of grid 3 by the debris removal component to fall into sludge hopper 21. At this time, isolation plate 20 drives sludge hopper 21 to move. Sludge hopper 21 drives connecting plate 22 to move, causing connecting plate 22 to gather and push the heavy object at the bottom of the interception device, so that it enters sludge hopper 21, completing the removal of debris. When the debris removal operation is completed, the staff starts the winding device 12 in reverse, causing the winding device 12 to rotate and retract the rope, thereby driving the dredging mechanism and collection mechanism to reset.
[0056] When cleaning the curved grid 3, the first separating rod 4 will drive the abutment block 24 to move. When the abutment block 24 moves from the concave part to the convex part of the grid 3, the grid 3 squeezes the abutment block 24, causing the abutment block 24 to move closer to the spring 26. This causes the abutment block 24 to squeeze the spring 26, at which time the spring 26 undergoes elastic deformation and accumulates elastic potential energy. When the abutment block 24 moves from the convex part to the concave part of the grid 3, the spring 26 releases its elastic potential energy and undergoes elastic deformation to push the abutment block 24, so that the abutment block 24 is tightly pressed against one side of the grid 3, ensuring the cleaning effect on the outer side of the grid 3.
