Description

Technical Field

[0001] The utility model belongs to the field of water pumps, and particularly relates to a large-flow sewage pump that is resistant to blocking. Background Art

[0002] The operating environment of sewage pumps often contains various impurities and garbage, which can easily cause blockage during use. Summary of the invention

[0003] The utility model aims to provide a large-flow sewage pump with anti-clogging function in view of the above-mentioned problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a large-flow sewage pump with anti-clogging, including a sewage pump body and a motor, characterized in that the sewage pump body is connected to the motor through a motor shaft, two mutually meshing gear shafts are arranged inside the sewage pump body, one end of the gear shaft is connected to an impeller shaft, the impeller shaft is provided with spiral teeth, an impeller is arranged at one end of the impeller shaft, a plurality of rod-shaped protrusions are arranged on the impeller, and the rod-shaped protrusions are arranged in an I-shape.

[0005] In the above-mentioned anti-clogging large-flow sewage pump, the spiral teeth are meshed with each other.

[0006] In the above-mentioned anti-clogging large-flow sewage pump, a bearing is arranged between the gear shaft and the impeller shaft.

[0007] In the above-mentioned anti-clogging large-flow sewage pump, the motor shaft is connected to one of the gear shafts.

[0008] Compared with the prior art, the anti-clogging large-flow sewage pump adopts two impeller shafts to drive the impeller to rotate, thereby increasing the flow rate of the sewage pump. The rod-shaped protrusions arranged on the impeller are used to crush and hang impurities, thereby reducing the possibility of blockage of the sewage pump during use.

[0013] 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.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, the anti-clogging large-flow sewage pump includes a sewage pump body 1 and a motor 2. The sewage pump body 1 is connected to the motor 2 through a motor shaft 3. Two mutually meshing gear shafts 4 are arranged inside the sewage pump body 1. One end of the gear shaft 4 is connected to an impeller shaft 5. The impeller shaft 5 is provided with spiral teeth 6. An impeller 7 is arranged at one end of the impeller shaft 5. A plurality of rod-shaped protrusions 8 are arranged on the impeller 7. The rod-shaped protrusions 8 are arranged in an I-shaped arrangement. The I-shaped arrangement can maximize the capture of impurities without hindering the normal operation of the impeller 7.

[0015] The spiral teeth 6 are meshed with each other, and a bearing 9 is provided between the gear shaft 4 and the impeller shaft 5. The motor shaft 3 is connected to one of the gear shafts 4. When starting, the motor 2 drives the motor shaft 3 to rotate, the motor shaft 3 drives the gear shaft 4 to rotate, and the gear shaft 4 drives the impeller shaft 5 to rotate. The two gear shafts 4 are meshed with each other, so that the two impeller shafts 5 rotate at the same time. The spiral teeth 6 on the impeller shaft 5 are meshed with each other, and the fine impurities entering the sewage pump body 1 are ground by mutual friction, which effectively increases the anti-blocking property of the sewage pump.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0017] Although the terms such as sewage pump body 1, motor 2, motor shaft 3, gear shaft 4, impeller shaft 5, spiral teeth 6, impeller 7, rod-shaped protrusion 8, bearing 9 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
