Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a cyclone aerator with filtration function. Background Technology

[0002] Cyclone aerators are highly efficient devices used in water and wastewater treatment systems. Their main function is to promote the aerobic degradation process of microorganisms by providing dissolved oxygen to the water. Cyclone aerators are suitable for a variety of applications, including municipal wastewater treatment, industrial wastewater treatment, eutrophication control, aquaculture, and the treatment of high-concentration wastewater. Their advantages are particularly pronounced in wastewater with high salinity, high oil content, high hardness, and a tendency to scale.

[0003] A cyclone aerator typically consists of nozzles, a hydrocyclone separator, and a layered cutting assembly. Air enters the aerator through the nozzles, mixes with water inside the cylinder, and undergoes collision and cutting, creating negative pressure at the bottom that draws in sludge, forming a vortex. The upper cutting module further agitates and cuts the fluid more thoroughly and evenly, generating microbubbles.

[0004] Traditional devices may lack an effective filtration system, or their filtration system may be inadequate, allowing larger debris in the wastewater to directly enter the cyclone aerator. This can not only clog the aeration holes but also affect the overall performance and efficiency of the aerator. Furthermore, traditional devices may lack convenient operating mechanisms. For example, additional tools or equipment may be required to remove and replace the filter screen, or a series of cumbersome steps may be needed to complete these operations. This not only increases the burden on operators but may also reduce work efficiency. Utility Model Content

[0008] The mounting flange is mounted on the connecting protrusion, and both the mounting flange and the connecting protrusion are provided with air inlet holes for gas to enter the cyclone cylinder.

[0009] The filter screen is snapped into the mounting flange.

[0010] A positioning component is disposed around the mounting flange for fixing the filter screen.

[0011] Furthermore, a fixing plate is provided on the inner wall of the cyclone cylinder, and a connecting pipe and a vent pipe are provided on the fixing plate, with a bubble generator provided on the connecting pipe.

[0012] Furthermore, a mushroom-shaped resistance head is provided on the inner wall of the top of the swirl cylinder.

[0013] Furthermore, the filter screen is provided with a pull block to facilitate its removal from the mounting flange.

[0014] Furthermore, the positioning component includes a sliding block and a positioning block; the sliding block is slidably disposed on the mounting flange, and the mounting flange is provided with a guide mechanism for driving the sliding block to slide; the positioning block is disposed on the sliding block and passes through the mounting flange to engage with the filter screen.

[0015] Furthermore, both the mounting flange and the filter screen are provided with through holes that mate with the sliding block.

[0016] Furthermore, the guiding mechanism includes a guide post, a threaded post, and a limiting plate; the guide post is disposed around the outer wall of the mounting flange and passes through both sides of the sliding block; the limiting plate is connected to the other end of the guide post; the threaded post passes through the limiting plate and is threadedly connected to the limiting plate, the bottom of the threaded post is rotatably connected to the sliding block, and a rotating block is provided at the top of the threaded post.

[0017] This utility model has the following beneficial technical effects:

[0018] This invention utilizes a combination of a filter screen and a positioning component. The filter screen effectively removes larger debris, such as leaves and plastic bags, from the wastewater before it enters the cyclone aerator. If these debris were to enter the aerator directly, they could clog the aeration holes or affect the aeration effect. When the filter screen needs cleaning or replacement, the operator can manually move the positioning block upwards to remove the filter screen, making it easier to remove and clean it. This removes dirt and impurities adhering to the screen, keeping it clean and unobstructed, thus improving the filtration effect. Attached Figure Description

The filter screen 13 is snapped into the mounting flange 3, and a pull block 14 is provided on the filter screen 13 to facilitate its removal from the mounting flange 3. Through filtration, suspended solids in the wastewater are reduced, allowing the vortex aerator to operate in clearer water, thereby improving aeration efficiency and dissolved oxygen transfer efficiency. The positioning assembly is located around the mounting flange 3 to fix the filter screen 13 in place.

[0027] As one embodiment of this utility model, please refer to the accompanying drawings. Figure 2 As shown, specifically, the inner wall of the swirl cylinder 2 is provided with a fixing plate 7, the fixing plate 7 is provided with a connecting pipe 8 and a vent pipe 6, the connecting pipe 8 is provided with a bubble generator 9, and the inner wall of the top of the swirl cylinder 2 is provided with a mushroom-shaped resistance head 10.

[0028] As one embodiment of this utility model, please refer to the accompanying drawings. Figure 4As shown, specifically, the positioning component includes a sliding block 16 and a positioning block 17; the sliding block 16 is slidably mounted on the mounting flange 3, and the mounting flange 3 is provided with a guide mechanism to drive the sliding block 16 to slide; the positioning block 17 is mounted on the sliding block 16 and passes through the mounting flange 3 to fit into the filter screen 13. Both the mounting flange 3 and the filter screen 13 have through holes that cooperate with the sliding block 16. The positioning block 17 can ensure that the filter screen 13 will not loosen or fall off due to water flow impact or vibration during use, thereby ensuring the stability and safety of the equipment. The filter screen 13 can remain stable when subjected to water flow impact, avoiding damage caused by shaking or twisting, and extending the service life of the filter screen 13.

[0029] As one embodiment of this utility model, please refer to the accompanying drawings. Figure 4 As shown, specifically, the guiding mechanism includes a guide post 11, a threaded post 12, and a limiting plate 15; the guide post 11 is disposed around the outer wall of the mounting flange 3 and passes through both sides of the sliding block 16; the limiting plate 15 is connected to the other end of the guide post 11; the threaded post 12 passes through the limiting plate 15 and is threadedly connected to the limiting plate 15, the bottom of the threaded post 12 is rotatably connected to the sliding block 16, and a rotating block 18 is provided on the top of the threaded post 12.

[0030] In summary, when using this utility model, the sewage conveying equipment is connected to the mounting flange 3. The sewage first undergoes preliminary filtration through the filter screen 13. The filtered water then enters the vortex cylinder 2 through the vent pipe 6. Inside the vortex cylinder 2, the water forms a vortex. Under the action of the bubble generator 9 and the mushroom-shaped resistance head 10, the gas-liquid mixture is repeatedly cut and broken. When the filter screen 13 needs maintenance due to long-term use, the rotating block 18 is manually rotated to drive the threaded column 12 to rotate, which in turn causes the sliding block 16 to slide on the guide column 11 until the positioning block 17 is released from the fixing of the filter screen 13. Then, the pulling block 14 can be pulled to remove the filter screen 13 from the mounting flange 3 for cleaning or replacement. This makes maintenance simpler and more convenient, keeps the filter screen 13 clean and unobstructed, and further improves the filtration effect of sewage.
