Problems solved by technology
Since the use of the sewage pump is under the liquid; the conveyed medium is some mixed liquid containing solid materials, which makes the rotating parts and impellers of the sewage pump bear greater pressure, and large solid particles and flexible impurities are often easy to Cause the impeller to block, make the sewage pump stuck, and sometimes even damage the sewage pump equipment itself
Makes the maintenance cost of the sewage pump high

Embodiment Construction
[0017] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0018] Such as figure 1 As shown, the sewage pump of this embodiment includes a pump body 1, a driving part 2 located on the upper part of the pump body, a pump shaft 3 connected to the driving part, and a main shaft connected to the pump shaft arranged inside the pump body. The blade 4, the liquid outlet 5 located on the pump body and the liquid outlet pipe 6 connected to the liquid outlet; the bottom of the pump body is provided with an inverted conical mesh plate 7 to surround the main blade in this In the space surrounded by the inverted conical mesh plate and the pump body, an auxiliary blade 8 is also arranged in the enclosed space. The auxiliary blade is locate...

The invention discloses a sewage pump, which comprises a pump body, a driving part located on the upper portion of the pump body, a pump shaft connected with the driving part, a main blade arranged in the pump body and connected with the pump shaft, a liquid outlet located in the pump body and a liquid outlet pipe connected with the liquid outlet, wherein an inverted-cone-shaped net plate is arranged at the bottom part of the pump body and surrounds the main blade in a space defined by the inverted-cone-shaped net plate and the pump body, an auxiliary blade is further arranged in the defined space, located below the main blade and connected with the pump shaft, the rotating direction of an impeller of the auxiliary blade is opposite to that of the main blade, the outer diameter of the auxiliary blade is not larger than half of that of the main blade, and the pump shaft extends downwards to penetrate through the inverted-cone-shaped net plate to be connected with the blade. According to the sewage pump, large solid particles and flexible materials are smashed and then lifted, the situation that the impeller is blocked and the sewage pump is stuck is avoided, and the maintenance cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a sewage pump. Background technique [0002] Sewage pump is a pump product used in the environmental protection industry to transport solid-liquid mixed liquid containing solid particles, fibers, etc., such as domestic sewage, industrial wastewater, mud, etc. plays a very important role in various industries. Since the use of the sewage pump is under the liquid; the conveyed medium is some mixed liquid containing solid materials, which makes the rotating parts and impellers of the sewage pump bear greater pressure, and large solid particles and flexible impurities are often easy to The impeller is blocked, the sewage pump is stuck, and sometimes even the sewage pump equipment itself is damaged. The maintenance cost of the sewage pump is high. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a se...
