Description

Technical Field

[0001] The utility model relates to the field of water decanters, in particular to a rotary water decanter. Background Art

[0002] In order to protect water resources and improve environmental quality, sewage treatment has become a vital task. In order to cope with different water quality and quantity, a rotary decanter is needed.

[0003] After searching, the Chinese patent announcement number: CN217498807U discloses a rotary decanter, including a decanter weir, both ends of which are rotatably provided with connecting plates; a buoy parallel to the decanter weir is fixedly installed on the connecting plate; a flip filter is provided on the liquid inlet side of the decanter weir, and the flip filter is blocked with the buoy. The utility model proposes a rotary decanter, which filters debris by providing a flip filter, and is also conducive to separating the debris on the flip filter.

[0004] In the prior art, although the above-mentioned device can filter and separate impurities, in actual operation, if there are too many or too large impurities, the filter screen may be quickly blocked, resulting in a decrease in the filtering effect or even complete failure. Moreover, even if the filter screen can be turned over to dump the impurities, it cannot be guaranteed that the impurities can be completely removed.

[0005] If all the wastewater is removed, some residue may clog the filter again. Secondly, in sewage treatment, the rotary decanter needs to ensure stable and effective operation according to different treated water volumes and liquid level fluctuations. However, the traditional decanter float design is often fixed and cannot flexibly adapt to changes in treated water volume and liquid level conditions. When the treated water volume is large or the liquid level fluctuates violently, the fixed float may not provide sufficient buoyancy, resulting in the decanter being unable to accurately follow the liquid surface, affecting the decanting effect, and even causing unstable equipment operation. On the contrary, when the treated water volume is small and the conditions are relatively simple, if the buoyancy of the float is too large, it will not only cause energy waste and cost increase, but also make the equipment structure too complicated and increase the risk of failure. Therefore, a rotary decanter is proposed to solve the above problems. Utility Model Content

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 - 3, An embodiment provided by the present utility model: A rotary water decanter, including a liquid collecting pipe 1. The right end of the liquid collecting pipe 1 is fixedly connected with a weir frame 2. The weir frame 2 is an existing device of the water decanter, which can ensure that the drained water flows along a specific direction, making the water flow more stable and orderly, reducing the turbulence and fluctuation of the water flow. The outer wall of the right end of the weir frame 2 is inserted with a filter frame 3. The filter frame 3 is provided with a filter net, which can block impurities through the filter net to reduce the possibility of blockage. A connecting mechanism is arranged on the inner wall of the weir frame 2. The right end of the connecting mechanism is fixedly connected with a threaded sleeve 6. The side wall of the filter frame 3 is fixedly connected with a connecting sleeve 7. Threads are arranged on the inner walls of the threaded sleeve 6 and the connecting sleeve 7, which can allow a bolt to penetrate to further improve the connection stability between the filter frame 3 and the weir frame 2. The bolt is not shown here and is an existing technology, so no more details will be described here. An adjusting component is arranged at the bottom end of the weir frame 2.

[0034] Refer to Figure 1 , Figure 4 and Figure 5 , The adjusting component includes a support frame 8. The support frame 8 mainly supports and connects the entire moving plate 9 and the floating cylinder 13. The support frame 8 is fixedly connected to the bottom end of the weir frame 2. The outer wall of the support frame 8 is slidably connected with a moving plate 9. The moving plate 9 supports and connects the floating cylinder 13. The inner wall of the bottom end of the moving plate 9 is elastically connected with a limiting rod 11 through a positioning spring 10. The right end of the moving plate 9 is fixedly connected with a plug rod 12. The outer wall of the plug rod 12 is inserted with a floating cylinder 13. The inner wall of the bottom end of the moving plate 9 is fixedly connected with one end of the positioning spring 10. When the limiting rod 11 moves upward, it will compress the positioning spring 10. When resetting, the elastic force of the positioning spring 10 is used to drive the limiting rod 11 to reset. The other end of the positioning spring 10 is fixedly connected with the inner side wall of the limiting rod 11. The limiting rod 11 penetrates and is slidably connected to the inner wall of the moving plate 9. A notch corresponding to the limiting rod 11 is opened on the inner wall of the moving plate 9, which can allow the limiting rod 11 to move vertically along the notch. The limiting rod 11 is inserted on the outer wall of the support frame 8. Multiple notches are opened on the support frame 8, and the notches correspond to the positions of the connected floating cylinders 13. Multiple groups of floating cylinders 13 are provided. The multiple groups of floating cylinders 13 are inserted into each other. There are protruding rods and corresponding notches on the side walls of the floating cylinders 13, which can meet the insertion combination of multiple floating cylinders 13.

[0035] Refer to Figures 1 - 3, The connecting mechanism includes a clamping plate 5 which is slidably connected to the inner wall of the weir frame 2. A notch is provided on the weir frame 2 to allow the clamping plate 5 to slide along the notch. The left end of the clamping plate 5 is elastically connected to the weir frame 2 through a return spring 4. A threaded sleeve 6 is fixedly connected to the right end of the clamping plate 5. The left end of the clamping plate 5 is fixedly connected to one end of the return spring 4. When the clamping plate 5 is pulled outwards, the return spring 4 will be stretched. When resetting, the elastic force of the return spring 4 is used to drive the clamping plate 5 to reset. The other end of the return spring 4 is fixedly connected to the inner wall of the left end of the weir frame 2. The clamping plate 5 is clamped on the side wall of the filter frame 3. A notch corresponding to the clamping plate 5 is provided on the filter frame 3 to allow the clamping plate 5 to be clamped with the filter frame 3 to limit the entire filter frame 3. And the side wall of the filter frame 3 is open to allow the left end of the clamping plate 5 to pass through the opening.

[0036] Working principle: When the filter frame 3 needs to be replaced, first, just twist the bolt to separate the bolt from the threaded sleeve 6 and the connecting sleeve 7. Then, pull the threaded sleeve 6 outwards to drive the clamping plate 5 to move outwards and stretch the return spring 4, so that the clamping plate 5 is separated from the notch on the side wall of the filter frame 3. Then, remove the filter frame 3 from the outer wall of the right end of the weir frame 2. During installation, just insert the filter frame 3 into the weir frame 2. Since the return spring 4 is in a stretched state at this time, when the notch on the side wall of the clamping plate 5 coincides with that of the filter frame 3, release the clamping plate 5 and use the reverse elastic force of the return spring 4 to drive the clamping plate 5 and the threaded sleeve 6 to reset. Finally, insert the bolt through the threaded sleeve 6 and the connecting sleeve 7 for further fastening.

[0037] When the water volume needs to be reduced by the floating cylinder 13, just pull the limit rod 11 upwards to separate the limit rod 11 from the notch on the outer wall of the support frame 8. Then, move the moving plate 9 to the right to separate the insertion rod 12 from the notch of the floating cylinder 13. Then, disassemble the single floating cylinder 13 one by one. When limiting is needed, just move the moving plate 9 to the left to insert the insertion rod 12 into the notch on the side wall of the floating cylinder 13. When the limit rod 11 coincides with the corresponding notch on the outer wall of the support frame 8, release the limit rod 11 and use the reverse elastic force of the positioning spring 10 to drive the limit rod 11 to reset, so that the limit rod 11 is inserted into the notch on the outer wall of the support frame 8. When multiple floating cylinders 13 need to be installed, just operate according to the above steps, and it can be adjusted according to the actual water decantation situation.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
