Description

A kind of high-pressure water jet coating eliminating equipment and method
Technical field
The present invention is to be related to a kind of coating eliminating equipment, more particularly to a kind of high-pressure water shot for surface coating removal Flow coat material eliminating equipment.
Background technique
Either non-skid coating, anticorrosive paint or decorative coating are all that method and substrate by sticking are connected to one It rises, it is extremely difficult to adopt the coating for removing be bonded together with substrate with machinery method in the case where not damaging substrate, is The method that this developed country takes the removal of high-pressure water jet coating.High-pressure water jet coating minimizing technology utilizes the dynamic of high pressure water Broken impact can be carried out to coating removes coating in turn.This method is completed coating in the case where preferably protection substrate and is removed Work, the coating waste-water of removing can be recycled by relevant apparatus and carry out harmless treatment, when avoiding coating removal work The pollution of dust and waste water to air and water source.
High-pressure water jet coating eliminating equipment is generally divided into two kinds of working methods at present, the main distinction in coating sewage whether It is handled by timely filtration, purification, i.e., working method with sewage water tank and with coating sewage water filtration purifying processing device Mode.
High-pressure water jet coating eliminating equipment composition and workflow with sewage water tank are as shown in Figure 1.High-pressure water shot Low pressure water is converted into high pressure water after sucking low pressure water in water tank 2 and feeds height by high-pressure hydraulic pump 3 when flow coat material eliminating equipment works Pressure water jet coating removes executing agency 4, while air compressor 5 removes the pneumatic of executing agency 4 to high-pressure water jet coating Motor (not shown) provides compressed air.Air motor drives rotary jet (not shown) to target coating surface The removal of rotating-spray high-pressure water jet progress coating.Waste paint and sewage mixture after removing is by vacuum reclaimer 6 Its own buffer tank (not shown) is sucked, is then discharged into sewage water tank 02 through discharge valve 01.Sewage water tank 02 fills with useless It is handled after abandoning coating and sewage mixture through equipment conveying to sewage treatment plant.
The high-pressure water jet coating eliminating equipment for having the advantages that sewage water tank is that equipment mechanism is simple, and disadvantage is waste paint It can deposit and be not easy to be discharged and clear up in water tank bottom.Since sewage water tank capacity is limited, sewage water tank needs to stop after filling sewage Machine draining, equipment is unable to continuous work, and waste paint and sewage mixture need to be transported to sewage treatment plant's processing.
High-pressure water jet coating eliminating equipment composition and workflow with coating sewage water filtration purifying processing device are such as Shown in Fig. 2.The main distinction with the high-pressure water jet coating eliminating equipment with sewage water tank is without sewage water tank, but increase To the open type filtrating equipment of the filter bag 03 of coating sewage finite filtration.The advantages of this equipment is that structure is simple, equipment volume is small, Disadvantage is to need to shut down filter bag together with discarded painting after open type filtrating equipment of the filter bag filter bag fills with waste paint and sewage mixture Removal is further processed material from container together with sewage mixture.It is filled when sock filtration precision is low through open type sock filtration The purified water for setting discharge, which still has a large amount of dirts, cannot be directly discharged to surrounding enviroment, open type filter bag when sock filtration precision is high Filter opening is blocked by dirt quickly, and water purification is difficult to be discharged, and needs to frequently replace filter bag, and working efficiency is very low.
The greatest drawback of above two high-pressure water jet coating eliminating equipment is that equipment cannot continuous sex work, equipment removal Waste paint and sewage mixture cannot effective fast purification separating treatment.
Summary of the invention
