Description

Technical Field

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

[0002] The pre-crushing device is an important component of the prefabricated pumping station. Its function is to pre-crush or crush solid waste or other difficult-to-pump materials before the liquid is pumped to the treatment or discharge point.

[0003] Publication No. CN220346061U discloses a pre-crushing device for an integrated prefabricated pump station, which relates to the technical field of prefabricated pump stations and includes a prefabricated pump casing, a water inlet pipe passing through the middle of one side of the prefabricated pump casing, a shell fixedly connected to the prefabricated pump station directly below the water inlet pipe, a water outlet provided at the bottom of the shell, a rotating shaft provided inside the shell, a blade provided on the outer surface of the rotating shaft, large gears provided in the middle of both sides of the shell, and a conveyor belt movably connected to the outer side of the large gear. The utility model provides a pre-crushing device for an integrated prefabricated pump station, which impacts the water collected from the outside onto the blades through the water inlet pipe, generates power through the rotation of the blades to drive the small gear to rotate, and is connected to the large gear through the conveyor belt, and 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. Although this type of pre-crushing device has the effect of cutting solid waste, it is lacking in preventing solid waste from splashing. Since this type of crushing device does not have a structure to prevent solid waste from splashing, this will lead to injuries to workers due to the splashing of solid waste when the garbage is crushed, thereby reducing the safety of the pre-crushing device.
