Technical Field

[0001] The utility model relates to the technical field of sludge pump lifting equipment, in particular to an electric lifting device for a sludge pump in a sewage treatment station. Background Art

[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. The sedimentation tank in the sewage treatment plant needs to be regularly pumped out with a sludge pump, and the sludge pump also needs to be regularly lifted for cleaning and maintenance.

[0003] Since the sludge pump sinks to the bottom of the pool, there is a lot of sludge attached to it. When it is lifted by lifting equipment, the sludge is easy to fall to the ground and cause pollution, requiring additional personnel to clean the ground, which increases the extra workload of cleaning the sludge pump. Therefore, we propose an electric lifting device for the sludge pump of a sewage treatment plant. Utility Model Content

An annular pipe is fixed around the outer ring of the bottom of a hanging plate, and tap water can be introduced into the annular pipe. During the lifting process of the sludge pump, the tap water enters and is sprayed out from a nozzle to flush the outer surface of the sludge pump and leave the sludge in a sedimentation tank. After the sludge pump is lifted, there is less sludge on the outer surface, and it is not easy to fall to the ground and cause pollution, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric lifting device for a sludge pump in a sewage treatment plant, comprising a crossbeam and a pillar, wherein the pillar is provided with two vertical supports on both sides of the bottom of the crossbeam, and a support plate is welded and fixed to the bottom of the pillar; a winch is installed in the middle position of the bottom of the crossbeam, and a hanging plate is fixed to the bottom of the main sling connected to the winch, and an annular ring tube is fixed to the bottom surface of the hanging plate, and a plurality of nozzles connected to the inside of the ring tube are provided on the bottom surface of the ring tube, and four connecting rings are evenly fixed to the bottom surface of the hanger plate of the inner circle of the ring tube.
