Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated pump stations, in particular to a pre-crushing device for an integrated prefabricated pump station. Background Art

[0002] Sewage treatment plants are generally located on the outskirts of cities. It is difficult for wastewater to flow to the sewage treatment plant by gravity. At this time, pumping stations are needed for lifting and transportation. In the process of collecting and treating wastewater, prefabricated pumping stations will mix some solid waste in the wastewater because the wastewater comes from different places. If the waste is not processed, it will cause damage to the pumping station, thereby reducing the efficiency of the pumping station and increasing the burden on maintenance personnel. Therefore, the solid waste must be crushed.

[0003] The publication (announcement) number is CN220346061U, which discloses a pre-crushing device for an integrated prefabricated pump station, and relates to the technical field of prefabricated pump stations, including a prefabricated pump casing, a water inlet pipe is passed through the middle of one side of the prefabricated pump casing, and a shell is fixedly connected to the prefabricated pump station directly below the water inlet pipe, and a water outlet is arranged at the bottom of the shell, and a rotating shaft is arranged inside the shell, and a blade is arranged on the outer surface of the rotating shaft, and large gears are arranged in the middle of both sides of the shell, and a conveyor belt is movably connected to the outer side of the large gear. The utility model provides a pre-crushing device for an integrated prefabricated pump station, and water collected from the outside is impacted onto the blades through the water inlet pipe, and the power generated by the rotation of the blades drives the small gear to rotate, and the large gear is connected through the conveyor belt. The large gear rotates the rotating shaft inside to drive the blade to cut the solid waste, thereby ensuring the normal use of the pump station and reducing the loss of manpower.

[0004] Although the above scheme completes the pretreatment by crushing through water impact, the operation of the crushing component requires the cooperation of a large number of transmission parts and the crushing component is fixedly assembled. It is difficult to assemble and maintain the crushing component. In addition, the crushed debris is mixed in the water body, the crushing effect of the equipment is unstable, and it is not convenient for personnel to centrally handle the crushed debris. For this reason, we propose a pre-crushing device for an integrated prefabricated pump station. Utility Model Content
