Description

Technical Field

[0001] This utility model relates to the technical field of environmental governance auxiliary devices, and in particular to a suspended chain aerator. Background Technology

[0002] As is well known, wastewater treatment is a crucial area in environmental protection, aiming to reduce water pollution and protect natural water bodies such as rivers, lakes, and oceans. The goal of wastewater treatment is to remove solids, nutrients, pathogens, and other harmful chemicals from wastewater, enabling the treated water to be safely discharged into the environment or reused. Suspended chain aerators are a key component of wastewater treatment equipment, primarily used to provide oxygen to microorganisms in the wastewater to promote the degradation of organic matter. These aerators typically consist of aeration heads, a suspended chain, and a drive unit, and can be suspended or suspended in the aeration tank.

[0003] An existing suspended chain aerator has been found to have issues with its aeration holes becoming clogged with suspended solids when the aeration pipes aerate water for extended periods. This can lead to pollution of the aerator and make it difficult for staff to clean, thus reducing the efficiency and effectiveness of wastewater treatment and resulting in poor practicality.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] like Figures 1 to 5As shown, the suspended chain aerator of this utility model includes two sets of driving devices 1, two sets of aeration pipe assemblies 2, and a filtration mechanism. One end of each of the two sets of driving devices 1 is evenly connected to one end of each of the two sets of aeration pipe assemblies 2. A filtration mechanism is provided on the outer side of each of the two sets of aeration pipe assemblies 2. The filtration mechanism includes an annular plate 3, two sets of arc-shaped locking blocks 4, an upper cover plate 5, a lower cover plate 6, four sets of filter screens 7, an auxiliary mechanism, and a fixing mechanism. The left end of one set of driving devices 1 is connected to the right end of the annular plate 3, and the inner side of the annular plate 3 is fitted onto the right end of the outer side of one set of aeration pipe assemblies 2. A set of locking grooves is provided at the top and bottom of the left end of the annular plate 3. The right ends of the two sets of arc-shaped locking blocks 4 are respectively engaged with the locking grooves of the annular plate 3. The right ends of the upper cover plate 5 and the lower cover plate 6 are respectively connected to the left ends of the arc-shaped locking blocks 4. The bottom of the upper cover plate 5 and the top of the lower cover plate 6 are tightly attached. Two sets of reserved holes are evenly provided on the upper cover plate 5 and the lower cover plate 6. Each of the pre-drilled holes in the upper cover plate 5 and the lower cover plate 6 is equipped with a set of filter screen plates 7. The right end of another set of drive devices 1 is clamped to the left end of the upper cover plate 5 and the lower cover plate 6 through a fixing mechanism. The bottom left end of the upper cover plate 5 and the top left end of the lower cover plate 6 are respectively tightly attached to one end of the aeration pipe assembly 2 through an auxiliary mechanism. First, the operator moves the upper cover plate and the lower cover plate to drive the arc-shaped locking block and the annular plate locking groove to engage, and make the upper cover plate and the lower cover plate tightly attached. Then, the fixing mechanism clamps and fixes the upper cover plate and the lower cover plate. Then, it can be used normally. When cleaning is required, the operator disassembles the upper cover plate and the lower cover plate by reversing the operation, and then cleans the impurities attached to their surfaces. This can effectively filter the aeration pipe, prevent suspended solids in the sewage from entering the aeration pipe and causing blockage, and allow the operator to quickly disassemble and clean, thereby improving the efficiency and effect of sewage treatment.

[0022] In a preferred embodiment of the above, the fixing mechanism includes two sets of mounting plates 8, two sets of connecting plates 9, two sets of connecting blocks 10, two sets of clamping plates 11, four sets of first locking blocks 12, and an adjustment assembly. The right end of one set of driving devices 1 is connected to the left end of each of the two sets of mounting plates 8. The right ends of the two sets of mounting plates 8 are slidably attached to the left ends of the connecting plates 9 via the adjustment assembly. One end of each of the two sets of connecting plates 9 is connected to one end of each of the connecting blocks 10, and the other end of each of the connecting blocks 10 is connected to one end of each of the clamping plates 11. The other ends of the two sets of clamping plates 11 are... The first locking blocks 12 are connected to one end of each of the two sets of first locking blocks 12. Each of the upper cover plate 5 and the lower cover plate 6 has a set of locking slots at its front and rear ends. The first locking blocks 12 are respectively engaged with the locking slots of the upper cover plate 5 and the lower cover plate 6. The operator can slide the two sets of connecting plates by adjusting the components, so that the two sets of connecting plates drive the clamping plates to slide through the connecting blocks until the two sets of clamping plates drive the first locking blocks to engage with the locking slots of the upper cover plate and the lower cover plate, respectively. This allows the operator to quickly install and remove the upper cover plate and the lower cover plate, thus enhancing its practicality.

[0023] As a preferred embodiment of the above, the adjustment assembly includes two sets of first screws 13 and two sets of first sliders 14. Each of the two mounting plates 8 has a set of sliding grooves at its right end. One end of each of the two sets of first screws 13 is rotatably connected to the sliding groove of the mounting plate 8. The two sets of first sliders 14 are threadedly connected to the first screws 13 and slidably connected to the sliding groove of the mounting plate 8. The right ends of the two sets of first sliders 14 are connected to the left end of the connecting plate 9. This allows workers to quickly slide the connecting plate by rotating the first screws, thus enhancing practicality.

[0024] As a preferred embodiment of the above, the auxiliary mechanism includes two sets of arc-shaped plates 15, two sets of arc-shaped pressure blocks 16, and a buffer assembly. The bottom left end of the upper cover plate 5 and the top left end of the lower cover plate 6 are respectively connected to one end of one set of arc-shaped plates 15. The other ends of the two sets of arc-shaped plates 15 are slidably fitted through the buffer assembly and one end of the arc-shaped pressure blocks 16, respectively. The other ends of the two sets of arc-shaped pressure blocks 16 are respectively tightly attached to one end of the aeration pipe assembly 2. By having the two sets of arc-shaped pressure blocks tightly attached to the aeration pipe assembly, the amount of impurities in the sewage entering the aeration pipe assembly through gaps can be effectively reduced, thus enhancing practicality.

[0025] As a preferred embodiment of the above, the buffer assembly includes multiple sets of damping rods 17 and connecting springs 18. Each of the two sets of arc-shaped plates 15 has a groove at one end, and each groove is uniformly connected to one end of one of the multiple sets of damping rods 17. Each of the two sets of arc-shaped pressure blocks 16 has one end uniformly connected to the other end of one of the multiple sets of damping rods 17. A connecting spring 18 is provided on the outer side of each of the multiple sets of damping rods 17, and each of the two sets of arc-shaped pressure blocks 16 slides and fits into the groove of one of the arc-shaped plates 15. Through the extension and retraction of the multiple sets of damping rods and connecting springs, damage to the aeration pipe assembly caused by forces generated by squeezing and friction can be reduced. Furthermore, the arc-shaped pressure blocks can always remain tightly attached to one end of the aeration pipe assembly, thus enhancing practicality.

[0026] As a preferred embodiment of the above, it also includes two sets of rotating handles 19, with one end of each of the two sets of first screws 13 passing through one end of the corresponding slide groove and connecting to one end of the rotating handle 19; this allows the operator to quickly rotate the first screw, thus enhancing practicality.

[0027] As a preferred embodiment of the above, it also includes four sets of sealing gaskets 20. The bottom of the upper cover plate 5 and the top of the lower cover plate 6 are respectively evenly connected to one end of two sets of sealing gaskets 20, and the other end of the two sets of sealing gaskets 20 is in close contact with the other end of the other two sets of sealing gaskets 20; this can effectively reduce wear caused by squeezing friction, thus enhancing practicality.

[0028] As a preferred embodiment of the above embodiment, it also includes four sets of limiting blocks 21. Each end of the groove of the two sets of arc plates 15 is provided with a set of sliding grooves. The four sets of limiting blocks 21 are slidably connected to the set of sliding grooves respectively. The two ends of the two sets of arc-shaped pressure blocks 16 are respectively connected to one end of a set of limiting blocks 21. This can effectively prevent the two sets of arc-shaped pressure plates from falling off the grooves of the arc plates, thus enhancing practicality.

[0029] The working principle of this suspended chain aerator is as follows: First, the operator moves the upper and lower cover plates, causing the arc-shaped locking block and the annular plate locking groove to engage, making the upper and lower cover plates fit tightly together. Then, the operator rotates the first screw by rotating the handle, and the two sets of first sliders start to drive the connecting plates to slide, so that the two sets of connecting plates drive the clamping plates to slide through the connecting blocks, until the two sets of clamping plates drive the first locking block to engage with the locking grooves of the upper and lower cover plates respectively. Then it can be used normally. When cleaning is required, the operator disassembles the upper and lower cover plates by reversing the operation, and then cleans the impurities attached to their surfaces.
