Water jet hull rust remover and operating method thereof

Abstract

The invention discloses a water jet hull rust remover and an operating method thereof. The rust remover comprises a high-pressure water tube interface, a high-pressure water tube interface seat, a rust removing disk, a high-pressure water tube interface seat support, a nozzle, and a nozzle rotary frame, and also comprises an air tube interface, an air tube interface seat, an air motor body, a vacuum recycling flange, a vacuum recycling tube, a vacuum recycling opening, and a high-pressure water sealing ring, wherein the vacuum recycling opening is embedded in the rust removing disk and connected with the vacuum recycling tube; the outlet end of the vacuum recycling tube is connected with the vacuum recycling flange; and the upper surface of the rust removing disk is also provided with a height adjusting support. The method comprises steps of height adjustment, rust removal and recycling. In the water jet hull rust remover, the rust removal by the superhigh pressure water jet and pumping and slag discharging by the vacuum system are compatibly designed into one body, the vacuum equipment recycles the rust, the high temperature, which is over 80 DEG C and generated by the water jet action, in the vacuum cavity can cause certain positive effects on the evaporation of water of the bulkhead, the rust removal drying is realized, and the hull is avoided from the return of rust.

Description

technical field [0001] The invention relates to a water jet derusting device, in particular to a water jet derusting device for a hull and a working method thereof. Background technique [0002] The mechanical process of derusting ships has gone through three stages of development: abrasive jet derusting, ultra-high pressure pure water jet derusting and ultra-high pressure pure water jet vacuum complete set of technology derusting. The abrasive jet derusting of water and sand type makes derusting with water a reality. In addition to abrasive splash pollution, wet derusting greatly eliminates environmental pollution. However, it is difficult to inject abrasives continuously and evenly in the abrasive jet rust removal of water and sand type, and the field application effect in shipyards and docks is not good. Although the ultra-high pressure pure water jet can solve the problem of continuous delivery of abrasives, after derusting by the pure water jet, due to the accumulation...

AI Technical Summary

Problems solved by technology

However, it is difficult to inject abrasives continuously and evenly in the abrasive jet derusting of water and sand type, and the field application effect in shipyards and docks is not good.

Although the ultra-high pressure pure water jet can solve the problem of continuous transportation of abrasives, after derusting by pure water jet, due to the accumulation of some water on the ship wall, it will soon cause the ship wall to rust again, that is, rust
