Description

Technical Field

[0001] This utility model relates to the field of sludge mixer impeller technology, specifically a submersible sludge mixer impeller assembly. Background Technology

[0002] Submersible sludge mixer impeller assemblies are key components used for mixing and agitating sludge in wastewater and sludge treatment processes. Their main function is to generate fluid motion through impeller rotation, helping to disperse and uniformly mix the sludge, preventing sedimentation, and promoting effective treatment. Impeller assemblies are typically made of corrosion-resistant and wear-resistant materials to withstand harsh underwater environments. Common designs include single-impeller or multi-impeller structures, with different shapes and sizes selected based on treatment requirements to achieve optimal mixing performance.

[0003] The impeller of a sludge mixer for wastewater treatment disclosed in Chinese Patent Publication No. CN117839471A addresses the issue that, during daily operation, the mixer runs continuously, and the degree of sludge pulverization is uncontrollable. This invention improves the impeller, enabling the mixer to effectively reduce sludge pulverization, stabilize operation, and increase efficiency. However, the overall functionality of the impeller assembly is relatively low. Underwater operations may cause the impeller to collide with debris in the sludge, potentially leading to impeller damage and affecting the long-term stability of the impeller assembly. Utility Model Content

[0004] The purpose of this invention is to provide an impeller assembly for a submersible sludge mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a submersible sludge mixer impeller assembly, including a mounting plate, a rotating mechanism is provided in the middle of the mounting plate, a connecting shaft is provided on one side of the rotating mechanism, a drill bit is fixedly connected to one side of the connecting shaft, main blades are fixedly connected at equal intervals on the outside of the connecting shaft, a material layer is provided inside the main blades, and protective wheels are provided at equal intervals on one side of the rotating mechanism.

[0006] Preferably, the rotating mechanism includes a rotating shaft rotatably connected to the middle position inside the mounting plate, one side of which is fixedly connected to the connecting shaft, and a first gear fixedly connected to the outside of the rotating shaft.

[0007] Preferably, the mounting plate has a second gear that rotates evenly at equal intervals inside, with one side meshing with the first gear, and a protective wheel is fixedly connected to one side of the second gear.

[0008] Preferably, the material layer includes a main substrate disposed inside the main blade, a strength layer disposed outside the main substrate, and a protective layer disposed outside the strength layer.

[0009] Preferably, the main substrate is made of carbon fiber composite material, the strength layer is made of tungsten carbide material, and the protective layer is made of polytetrafluoroethylene coating.

[0010] Preferably, the protective wheel is made of ceramic matrix composite material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This submersible sludge mixer impeller assembly has multiple sets of second gears inside the mounting plate. When the shaft drives the second gears to rotate through the first gear, the multiple sets of second gears can drive the protective wheel to rotate at high speed on the outside of the rotating mechanism. At this time, the protective wheel can effectively break up large pieces of debris and prevent them from damaging the main blades. At the same time, when the protective wheel rotates at high speed, it will generate strong turbulence and shear force around the main blades, further breaking up solid particles in the sludge, making the sludge mix more uniform, and improving the overall functionality and long-term safety of the impeller assembly.

[0013] 2. This submersible sludge mixer impeller assembly, by setting a main body, a strength layer, and a protective layer inside the main blade, can effectively increase the overall strength of the main blade and enable the main blade to withstand a large load. The outermost protective layer can effectively reduce the friction coefficient and prevent sludge adhesion. At the same time, the protective wheel is made of ceramic matrix composite material, which has extremely high strength and can effectively protect the main blade, improve the performance and life of the impeller assembly, and improve the overall safety and stability of the impeller assembly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A submersible sludge mixer impeller assembly includes a mounting plate 1. A rotating mechanism 2 is located in the middle of the mounting plate 1. A connecting shaft 3 is located on one side of the rotating mechanism 2. A drill bit 301 is fixedly connected to one side of the connecting shaft 3. Main blades 4 are fixedly connected at equal intervals to the outside of the connecting shaft 3. A material layer 5 is provided inside the main blades 4. Protective wheels 6 are evenly arranged at equal intervals on one side of the rotating mechanism 2. The main blades 4 are curved blades, which can more effectively push the water flow, enabling the mixer to generate a larger flow rate and volume in the submersible environment.

[0022] The rotating mechanism 2 includes a rotating shaft 201 rotatably connected to the middle position inside the mounting plate 1, which is fixedly connected to the connecting shaft 3 on one side. A first gear 202 is fixedly connected to the outside of the rotating shaft 201. A second gear 203 is rotatably connected at equal distances inside the mounting plate 1, which meshes with the first gear 202 on one side. A protective wheel 6 is fixedly connected to one side of the second gear 203. The rotating shaft 201 drives the first gear 202 to rotate, so the first gear 202 can drive multiple sets of second gears 203 to rotate, and the second gear 203 drives the protective wheel 6 on one side to rotate, while significantly increasing the speed of the protective wheel 6.

[0023] Example 2 differs from Example 1 mainly in that:

[0024] A submersible sludge mixer impeller assembly includes a main substrate 501 disposed inside the main blade 4 in the material layer 5, a strength layer 502 disposed outside the main substrate 501, and a protective layer 503 disposed outside the strength layer 502.

[0025] The main body 501 is made of carbon fiber composite material, which is lightweight, high-strength, can withstand large loads, has good fatigue resistance, and extends service life.

[0026] The strength layer 502 is made of tungsten carbide, which has high hardness and good wear resistance. It is firmly bonded to the main substrate 501 and is not easy to fall off.

[0027] The protective layer 503 is made of polytetrafluoroethylene coating, which has low surface energy, making it difficult for sludge to adhere, and its low coefficient of friction can reduce operating resistance and energy consumption.

[0028] The protective wheel 6 is made of ceramic matrix composite material, which has extremely high strength and can withstand huge impact forces. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] In use, the embodiment of this application is as follows: the rotating shaft 201 is driven to rotate by an external drive motor, and the rotating shaft 201 can drive the first gear 202 to rotate in the mounting plate 1. At this time, the first gear 202 can drive multiple sets of second gears 203 around it to rotate at high speed. At this time, the rotating shaft 201 can drive the main blade 4 to rotate through the connecting shaft 3. At the same time, the second gear 203 can drive the protective wheel 6 on one side to rotate at a high speed. The main blade 4 can quickly stir the sludge, and the protective wheel 6 can quickly crush underwater debris.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
