Abstract

The invention discloses a prefiltering device for oil-containing waste liquid in ship production. The device comprises a treating box, wherein a mounting rack is fixed inside the treating box, a meshscreen is fixed on the mounting rack, a stirring mechanism is arranged on the upper side of the mesh screen, a first servo motor is arranged on the outer side of the treating box, an output shaft of the first servo motor is connected with a first belt pulley, second belt pulleys are in transmission connection to two sides of the first belt pulley, each second belt pulley is in key connection witha screw rod, a transmission nut is in threaded connection on each screw rod, the transmission nuts are inlaid in a material pushing plate, connecting rods are welded to two sides of the upper end of the material pushing plate, a material baffle block is welded to the end parts of the connecting rods, and is in tight contact with a discharge hole, and a recycling box is arranged on the lower side of the discharge hole. Through the structure, filtered impurities can be automatically discharged and recycled, the filtering speed is increased through stirring for the liquid, and further, work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of waste liquid pre-filtration in ship production, and in particular relates to a pre-filter device for oily waste liquid in ship production. Background technique [0002] A ship is a man-made means of transportation that mainly operates in geographical waters. It is a means of transportation that can sail or berth in waters for transportation or operation. It has different technical performance, equipment and structural types according to different requirements for use. The interior of the ship mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. [0003] In the prior art, in ship production, it is necessary to paint the steel surface of the ship, that is, the surface of the hull shell. Before painting, rust removal is required. The method of rust removal will add a large amount of rust remover, emulsion, ...
