Description
Technical Field
The invention relates to the technical field of sand blasting equipment, in particular to a heating remote control type water mist sand blasting machine with a mushroom head improved structure.
Background
The surface of the steel structure is typically sandblasted prior to painting using a sandblasting apparatus to remove tarnishing and other attachments from the surface. The current sand blasting equipment mainly comprises three types:
the first is a dry blasting apparatus which uses compressed air as a power source to blast sand onto the surface of a workpiece for a rust removal process. When the dry sand blasting equipment is adopted for sand blasting, dust pollution is large, and the surrounding environment is greatly and negatively affected.
The second type is wet sand blasting equipment, which uses the negative pressure siphon action (compressed air positive pressure delivery can also be adopted) of water jet ejected by a high-pressure water cleaning machine, adopts a post-mixing mode, adds solid abrasive materials with proper labels into the high-pressure water jet, and uses the actions of jet impact, shearing and the like of solid-liquid mixed fluid to carry out rust removal treatment. The wet sand blasting equipment has the advantages of lower construction efficiency, high accessory abrasion rate and short service life.
The third is water sand blasting equipment, which uses compressed air as a power source, uses nonmetallic abrasive with extremely small granularity as a medium, uses a small tank body to mix the abrasive with water for sand blasting, and has higher efficiency than wet sand blasting equipment. The existing water sand blasting equipment mainly comprises an inlet, is high in price, structurally adopts a single tank body and a single spray gun structure, only uses nonmetallic abrasive with extremely small granularity as a medium, and is limited in application.
The Chinese patent application with publication number of CN 108747848A discloses a control system of a double-gun water mist sand blasting machine; the Chinese patent application with publication number of CN 108705455A discloses a general double-gun water mist sand blasting machine; chinese patent application publication No. CN 108481210a discloses a water mist abrasive blasting machine; chinese patent application publication No. CN 108857923a discloses a top valve control device for a water mist abrasive mixing cylinder.
