A double-pipe anti-splash paint spraying device

Abstract

The invention discloses a double-pipe splashing-preventive coating spray device which is characterized by comprising a spray nozzle and a spray rod. The spray nozzle is mounted at the front end of the spray rod and is coaxial with the spray rod, a boss which radially outwardly extends is arranged on the spray rod, an inner cylinder and an outer cylinder which are coaxial with the spray rod are respectively arranged on the outer side of the spray rod, the inner cylinder is arranged inside the outer cylinder, annular bottoms which are butted to each other are arranged at the rear end of the inner cylinder and the rear end of the outer cylinder, the inner cylinder and the outer cylinder are closely connected with the boss by the annular bottoms, the front end of the outer cylinder exceeds the front end of the inner cylinder, the front end of the inner cylinder exceeds the spray nozzle, and air holes are peripherally formed in the side walls, which are positioned at the rear of the spray nozzle, of the inner cylinder. The double-pipe splashing-preventive coating spray device has the advantages of little coating wastage and environmental pollution and capability of reducing hazards to spray personnel.

Description

technical field [0001] The invention relates to a tool used in paint spraying, in particular to a double-pipe anti-splash paint spraying device. Background technique [0002] Paint is a common wall decoration material in our life to beautify our life. In the past, paint was applied to the wall by brush. With the advancement of technology and the emergence of automatic spraying equipment, most of the paint is now passed through high-pressure machines. Spraying on the wall has the advantages of high efficiency, uniform and dense coating, and high appearance consistency compared with traditional brushing. However, spraying also has some shortcomings. After arriving at the wall, it changes direction around, most of the atomized paint is in contact with the wall surface and adheres to the wall, and some of the peripheral smaller atomized particles will be taken away by the scattered airflow, which not only wastes the paint, but also falls and pollutes The parts that do not need ...
