Description

Technical Field

[0001] The invention relates to the technical field of sewage discharge equipment, and more specifically to a self-stirring submersible sewage discharge pump that does not require lifting. Background Art

[0002] After sedimentation, the sewage pool will form an upper clear liquid layer and a lower sediment sand layer. At this time, in order to retain the upper clear liquid layer, a submersible sewage pump is needed to extract the bottom sediment sand layer. The submersible sewage pump is generally a vertical structure. When working, the pump body is immersed in water. It can effectively pass fiber materials with a diameter of five times the pump diameter and solid particles with a diameter of 50% of the diameter. However, the submersible sewage pump under the existing technology still has the following shortcomings in actual use;

[0003] First, when the submersible sewage pump under the prior art is in use, the suction pipe at the bottom is placed in the sediment layer to extract sewage. The impurity particles in the extracted sewage will inevitably re-aggregate in the suction pipe and adhere to the inner side of the pipe wall, which can easily cause the pipeline of the submersible sewage pump to be blocked. However, the submersible sewage pump under the prior art does not have the function of solving this problem.

[0004] Secondly, in order to improve the pumping power of sewage, the submersible sewage pump of the prior art has a high water pressure when pumping sewage. When sewage is discharged from the outlet pipe, it is easy to cause impact on the pipe mouth. Long-term water discharge is easy to cause damage to the pipe mouth. However, the submersible sewage pump of the prior art does not have a buffering effect on the high-pressure water flow to protect the outlet pipe mouth when discharging liquid.

[0015] 1. The present invention is provided with a stirring assembly. When the device is working, the sewage flow moves upward at a high speed in the suction pipe, so that the clear liquid on the upper layer is sucked from the liquid flow pipe into the bottom of the suction pipe to wash the inner wall of the suction pipe.

[0016] 2. The present invention is provided with a drainage assembly. When the high-pressure sewage flow is discharged from the liquid outlet pipe, it will first impact the buffer plate. The impact force causes the buffer plate to move upward, thereby pulling the cables on both sides. After the cables are pulled, they begin to pull the upper movable curved sleeve to move to both sides, thereby expanding the opening composed of the intermediate plate, the curved plate and the corrugated folding plate. When the water pressure decreases or the drainage stops, under the action of the spring and the reset spring, each structure begins to reset. The above structure can effectively buffer the high-pressure sewage flow discharge process, and can expand the water outlet opening under high pressure, thereby protecting the drainage port from being damaged by the high-pressure water flow.
