Description

Technical Field

[0001] This utility model relates to the field of aerator technology, and in particular to a novel high-speed small impeller for use in aerators. Background Technology

[0002] The high-speed impeller of an aerator is a key component, characterized by its small size (its diameter is typically smaller than that of a regular impeller, ranging from tens of centimeters to about one meter depending on the aerator model and application), high rotational speed (driven by a dedicated motor, reaching hundreds or even thousands of revolutions per minute), and special blade shape (designed with specific curvatures and angles to optimize water agitation and oxygen dissolution; common blade shapes include twisted and spiral shapes, which help generate powerful water flow and vortices during high-speed rotation).

[0003] When workers need to increase the oxygen content in the water, they install impellers on aerators so that the aerators can drive the impellers to oxygenate the water. However, existing small impellers are usually installed with multiple bolts, which requires workers to spend a lot of time disassembling the bolts when maintaining the small impellers, thus reducing the efficiency of workers in maintaining the small impellers. Utility Model Content

[0004] The purpose of this invention is to solve the problem of reduced efficiency in the maintenance of small impellers by workers in the existing technology, and to propose a new type of high-speed small impeller for use in aerators.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel high-speed small impeller for use in an aerator, comprising a rotating wheel, a rotating shaft, and a disassembly device. The rotating shaft is placed on the upper surface of the rotating wheel, and the disassembly device is disposed on the upper surface of the rotating wheel. The disassembly device includes a connecting rod, which is fixedly connected to the upper surface of the rotating wheel. A sleeve hole is formed on the upper surface of the rotating shaft, and the sleeve hole is fitted onto the surface of the connecting rod. A guide block is fixedly connected to the upper surface of the rotating shaft, and a sliding plate is slidably connected to the outer side of the guide block. The sliding plate is slidably connected to the upper surface of the rotating shaft, and a retaining strip is fixedly connected to one end of the sliding plate. The retaining strip is inserted into the interior of the connecting rod. An insert rod is placed on the upper surface of the guide block, and the insert rod is inserted into the interior of the rotating shaft and the sliding plate. A guide rod is fixedly connected to the upper surface of the guide block, and the insert rod is slidably connected to the outer side of the guide rod. The guide rod can cooperate with the guide block to guide the insert rod to slide.

[0006] Preferably, a push spring is fixedly connected between the guide rod and the insertion rod. The push spring is located above the rotating shaft and can cooperate with the guide rod and the insertion rod to limit the sliding of the insertion rod. The rotating wheel is an integral structure.

[0007] Preferably, the upper surface of the rotating wheel is provided with a protective device, the protective device including a placement ring, the placement ring being placed on the upper surface of the rotating wheel, the rotating shaft being inserted into the inner side of the placement ring, and the placement ring being able to cooperate with the rotating wheel to achieve the purpose of supporting the placement ring.

[0008] Preferably, a plurality of anti-slip blocks are fixedly connected to the upper surface of the rotating wheel, and the placement ring is fitted onto the surface of the anti-slip blocks. The anti-slip blocks can cooperate with the rotating wheel to restrict the rotation of the placement ring.

[0009] Preferably, the internal threads of the two anti-slip blocks are connected to a limiting block, which is placed on the upper surface of the placement ring. The limiting block can cooperate with the anti-slip blocks to restrict the placement ring.

[0010] Preferably, a support frame is fixedly connected to the outer side of the placement ring, and an isolation net is fixedly connected to one end of the support frame. The isolation net is sleeved on the outer side of the rotating wheel, and the support frame can cooperate with the placement ring to achieve the purpose of supporting the isolation net.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up a disassembly device, when the worker needs to maintain the small impeller, he pulls the insert rod upward. The insert rod is guided by the guide rod, and the insert rod disengages from the rotating shaft and the slide plate, pushing the locking strip. The locking strip pushes the slide plate, and the slide plate is guided by the guide block. The locking strip disengages from the connecting rod, releasing the insert rod, and the insert rod abuts against the slide plate. By setting up the disassembly device, the worker can effectively and conveniently maintain the small impeller, avoiding the time-consuming situation when disassembling the small impeller, thereby improving the efficiency of the worker in maintaining the small impeller.

[0013] 2. In this utility model, by setting up a protective device, when workers need to block debris on the water surface, the placement ring is placed on the upper surface of the rotating wheel. The placement ring drives the support frame, and the support frame drives the isolation net to be fitted onto the outside of the rotating wheel. The limiting block is inserted into the anti-slip block and rotates. The limiting block is connected to the internal thread of the anti-slip block. The limiting block tightens and presses down on the placement ring. When the rotating wheel rotates, the rotating wheel drives the isolation net to rotate. By setting up the protective device, debris on the water surface can be effectively blocked, avoiding damage to the surface of the impeller, thereby improving the service life of the impeller.

The insert rod 36 is inserted into the interior of the rotating shaft 2 and the slide plate 38.

[0025] Specifically, a guide rod 34 is fixedly connected to the upper surface of the guide block 37, and the insertion rod 36 is slidably connected to the outer side of the guide rod 34. The guide rod 34 can cooperate with the guide block 37 to guide the insertion rod 36 to slide.

[0026] Specifically, a push spring 35 is fixedly connected between the guide rod 34 and the insertion rod 36. The push spring 35 is located above the rotating shaft 2, and the rotating wheel 1 is an integral structure.

[0027] In this embodiment, the push spring 35 can cooperate with the guide rod 34 and the insertion rod 36 to restrict the sliding of the insertion rod 36.

[0028] In this embodiment: a protective device 4 is provided on the upper surface of the rotating wheel 1.
