Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of submersible pumps, and in particular relates to an impeller assembly for a submersible pump. Background Art
[0002] In our daily life, there are wastewater tanks full of garbage, such as diapers, chopsticks, plastic bags and other garbage. Sometimes we need to clean and disinfect the wastewater tanks, so we need to pump out the garbage and wastewater in the wastewater tanks. However, the existing submersible pumps generally use a cutting device at the water inlet to cut the garbage to deal with this problem. However, the cutting device of the existing submersible pump can only cut specific garbage and cannot meet the needs of processing multiple types of garbage in the wastewater tank. Utility Model Content
[0003] The purpose of the utility model is to provide an impeller assembly for a submersible pump in view of the above problems existing in the prior art.
[0004] The purpose of the utility model can be achieved through the following technical solutions: an impeller assembly for a submersible pump, characterized in that it includes an impeller body and a suction cover, the impeller body is provided with a water inlet and a water outlet, blades are provided inside the impeller body, the blades are orthogonally bent around the suction direction, the suction cover is rotatably connected to the impeller, and the suction cover is provided with a through hole connected to the water inlet.
[0005] The working principle of the utility model is as follows: the impeller is directly mounted on the output shaft of the output motor, and a shell is provided outside the impeller, which is used to connect the drive motor and the suction cover so that the impeller can rotate stably. When the drive motor drives the impeller to rotate, the impeller drives the liquid and garbage to be sucked into the impeller from the water inlet and discharged from the water outlet. The blades of the present application are in the form of single blades, and the curvature of the blades is gradually increased, so that the amount of sewage and garbage that can be processed within a certain period of time is increased, and different types of garbage can be extracted and sucked. This product is suitable for environments without particularly large garbage, and can directly extract daily household garbage, such as diapers, plastic bags, disposable chopsticks, etc., without being blocked inside the impeller.
[0006] In the above-mentioned impeller assembly for a submersible pump, the suction cover is provided with a limiting groove for inserting the impeller.
[0007] In the above-mentioned impeller assembly for a submersible pump, the impeller has weight-reducing grooves on both the top and bottom surfaces. In the above-mentioned impeller assembly for a submersible pump, the impeller has counterweights on both the top and bottom surfaces. In the above-mentioned impeller assembly for a submersible pump, a weight-reducing cavity is provided inside the impeller.
[0008] Compared with the prior art, the utility model has the advantage of being able to cut most of the domestic garbage. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] like Figure 1-Figure 5 As shown, the impeller assembly for the submersible pump comprises an impeller body 1 and a suction cover 2. The impeller body 1 is provided with a water inlet 3 and a water outlet 4. Blades 5 are provided inside the impeller body 1. The blades 5 are orthogonally bent around the suction direction. The suction cover 2 is rotatably connected to the impeller and is provided with a through hole 6 connected to the water inlet 3.
[0017] To be more specific, the suction cover 2 is provided with a limiting groove 7 for the impeller to be inserted into. This arrangement is used to ensure the stability of the impeller's rotation and at the same time ensure a tight fit between the impeller and the suction cover 2.
[0018] To elaborate further, weight-reducing grooves 9 are provided on the top and bottom surfaces of the impeller. Since the blades 5 of the present application adopt a single-blade 5 type, the weight of the impeller is unevenly distributed, so it is easy to shake during rotation. Therefore, weight-reducing grooves 9 are provided on the top surface and the ground corresponding to the position of the blade 5, so that the mass of the impeller at this location is reduced, and the mass of the impeller at different positions is ensured to be the same as much as possible.
[0019] To elaborate further, counterweights 8 are provided on the top and bottom surfaces of the impeller. Since the blades 5 of the present application are of a single-blade 5 type, the weight of the impeller is unevenly distributed, so it is prone to shaking during rotation. Therefore, counterweights 8 are provided on the top surface and the ground corresponding to the position where there are no blades 5, so that the mass of the impeller at this location is increased, and the mass of the impeller at different positions is ensured to be the same as much as possible.
[0020] In further detail, a weight reduction cavity 10 is provided inside the impeller, which is used to reduce the mass of the blades 5 and at the same time reduce the materials required for production and reduce costs.
[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
[0022] Although a large number of terms are used in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
