Description

Technical Field

[0001] The invention relates to the technical field of ship sewage treatment, and in particular to a mobile dock sewage lifting device. Background Art

[0002] According to the current sewage discharge requirements for inland ships in my country, ships sailing on rivers cannot discharge the sewage they generate directly into the waters, but need to transfer it to the sewage treatment system on shore and undergo environmental protection treatment to meet standards before they can be discharged. Therefore, when the sewage generated by sailing ships is moored at the dock by the river, a sewage pump is needed to pump the sewage from the ship into the sewage treatment system on the dock platform to free up the volume of the ship's sewage tank.

[0003] The existing dock sewage lifting device usually connects the ship's sewage tank and pump body, and extracts the sewage in the sewage tank to the sewage treatment system of the dock through a pipe. This treatment method requires the pipe to be connected to the ship's sewage tank. The longer the connection distance, the higher the requirement for the sewage pump. The dock can usually only be set at a fixed point, and the ships passing by need to queue up at the sewage lifting position and carry out sewage lifting and discharge work in turn, which will cause congestion at the dock and waste time. For this reason, a mobile dock sewage lifting device is proposed. A track is set at the dock. The sewage lifting device can be moved to the ship's sewage tank according to the position and length of the ship, and can be adjusted in height according to the water surface height and the height of the ship, so that the sewage pump can be adjusted to the height of the corresponding sewage tank and connected to it, and transported to the mobile sewage tank through a pipe for temporary storage. The sewage tank is movable and can be temporarily connected to the sewage lifting device. It can be dismantled and moved after it is full, so that the edge of the dock can be used for sewage lifting treatment, which can effectively improve the ship sewage treatment efficiency of the dock.
