Sucker device for ultrahigh-pressure water jet cleaning of plate surface and jet equipment

Abstract

The invention provides a suction cup device for ultrahigh-pressure water jet cleaning of the surface of a plate and jet equipment. Wherein the sucker device comprises a sucker, an injector head and a thrust device. The suction cup comprises a cup body and an edge structure wound around the outermost ring of the cup body, the edge structure is provided with a sealing face attached to the surface of the plate in a contact mode, and the cup body is provided with a water conveying opening and a recycling opening. The spraying head is installed in the disc body and used for being communicated with a high-pressure water conveying pipe penetrating through the water conveying opening, and high-pressure water sprayed out of the spraying head is discharged out of the disc body through the recovery opening. The thrust device is installed on the disc body, the installation position of the thrust device corresponds to the edge structure, and the thrust device is used for enabling the sealing face of the edge structure to be matched with the surface shape of a plate to be in contact so as to construct a closed space between the disc body and the surface of the plate. According to the technical scheme, the sealing face of the suction cup can be effectively attached to the flat plate surface and the uneven plate surface, and the problem of sewage leakage after high-pressure water cleaning is reduced or even eliminated.

Description

technical field [0001] The present application relates to the technical field of derusting and paint removal on the surface of plates, in particular, to a sucker device and spraying equipment for ultra-high pressure water jet cleaning on the surface of plates. Background technique [0002] In the process of ship construction and repair, the plates of the ship need a lot of cleaning operations such as grinding, rust removal and paint removal. The conventional method is to use a large amount of steel grit to spray the outer surface of the plate through compressed air or high-pressure water to complete the cleaning construction such as grinding, rust removal, and paint removal. healthy. [0003] With the increasingly stringent environmental protection requirements and the vigorous promotion of green shipbuilding, many shipbuilding companies have used ultra-high pressure water jet technology to replace traditional steel sanding, rust removal, and paint removal operations.

Problems solved by technology

In the process of cleaning the surface of the board with ultra-high pressure water, first the suction cup is attached to the surface of the board, and then the ultra-high pressure water is transported into the suction cup to clean the surface of the board and recovered through the recovery port on the suction cup. However, when the suction cup encounters a slope When the surface of the sheet is not clean, or when the suction cup meets the uneven surface of the sheet with shaped lines intersecting, the suction cup cannot fully attach to the surface of the sheet, causing the sewage after high-pressure water cleaning to leak from the gap between the suction cup and the sheet, resulting in the surface of the sheet after cleaning There is a lot of flash rust, or secondary pollution, and the plate needs to be reworked and cleaned

It can be seen that the sucker device of the prior art not only leads to incomplete cleaning, but also increases the cost and time of rework and affects the construction progress.
