Description

Novel double-layer jet hydraulic derusting spray gun and use method thereof

Technical Field

The invention relates to the field of rust removal spray guns, in particular to a novel double-layer jet hydraulic rust removal spray gun and a using method thereof.

Background

The shot blasting rust remover is a method for removing rust on the surface of steel by throwing steel shots with a certain particle size by centrifugal force of a throwing head by utilizing high-speed operation of mechanical equipment and violently colliding and striking the thrown steel shots and members. The steel shots used by the method comprise the following varieties: the cast iron shots and the steel wire cut shots are two kinds, the cast iron shots are iron shots with the granularity of 0.8-5 mm formed by molten iron under the conditions of injection and quick cooling, and the surface is round. It is relatively inexpensive but less durable. The iron shots are crushed by repeated impact in the shot blasting process and are discharged as dust. The steel wire cutting pill is formed by cutting a steel wire of a waste steel wire rope into small sections of 2mm, the surface of the steel wire cutting pill is provided with sharp corners, the rust removing effect is relatively high, the steel wire cutting pill is not easy to break, the service life is prolonged, and the price is improved. The shot blast surface of the latter is rougher.

The sand blasting rust remover utilizes high-pressure air to bring out quartz sand and spray the quartz sand on the surface of a component to achieve the rust removing method. The sources of the quartz sand are as follows: river sand, sea sand, artificial sand, and the like. The sand has low cost and wide sources, but has great environmental pollution; the rust removal is completely operated manually, and the surface roughness of the member after rust removal is small, so that the requirement on the friction coefficient is not easy to meet.

The existing derusting spray gun has high purchasing cost and pressure, and can generate a lot of dust to seriously pollute the environment and cause great harm to the bodies of operators, such as pneumoconiosis and the like.
