Abstract

The invention discloses a locally controlled hydraulic oil-containing sludge spiral conveying pump. The locally controlled hydraulic oil-containing sludge spiral conveying pump comprises a pump main body; the pump body comprises a feeding pipeline, a stator and a discharging pipeline which are horizontally and coaxially arranged and are of an integrated structure, a feeding hopper is arranged on the feeding pipeline, the feeding hopper is installed at the feeding end of the feeding pipeline through a bolt assembly, and a rotating shaft with a spiral sheet is horizontally arranged in the feeding pipeline; the end part, away from the stator, of the feeding pipeline is connected with a hydraulic driving mechanism for driving the rotating shaft to work through a flange; and the other end of the rotating shaft is connected with the rotor in the inner cavity of the stator through a universal joint. The locally controlled hydraulic oil-containing sludge spiral conveying pump has the beneficial effects that oily sludge with various characteristics such as dryness, viscosity, dryness and thinness can be pumped, hydraulic driving is adopted, the explosion-proof requirement can be met, localcontrol can be realized, each interface is designed into a quick joint mode, namely, a pump outlet, a hydraulic motor interface and the like are designed into quick joints, a feeding trough is also designed into a detachable structure, and the equipment is convenient to disassemble and assemble.

Description

technical field

[0001] The invention relates to a conveying pump, in particular to a locally controlled hydraulic oily sludge screw conveying pump, which belongs to the technical field of environmental protection machinery. Background technique

[0002] During the daily operation of the tanker, there will be oil residue or sediment at the bottom and corners of the oil tank. After crude oil washing tank or water washing tank, there are still some remaining oil sludge that cannot be washed cleanly, and manual cleaning is required to remove the garbage inside. Wait until it is cleaned up to meet safety requirements. The process of cleaning up the remaining oil residue or garbage in the cabin is tank cleaning. According to the national environmental protection, the cargo owner’s cleaning requirements for the cabin of the ship that is changing the type of cargo, and the situation that the ship enters the factory for repairs, it is necessary to carry out the tank cleaning operatio...
