Sealed hood for automatic blasting and descaling

Abstract

The invention provides a sealing cover for automatic sandblasting rust removing. The sealing cover comprises an upper portion sandblasting chamber, a middle portion sandblasting chamber, a lower portion sandblasting chamber and a hair brush, wherein the upper portion sandblasting chamber, the middle portion sandblasting chamber and the lower portion sandblasting chamber are sequentially connected,and the one side of the middle portion sandblasting chamber is provided with a sand returning pipe joint. According to the present invention, during the sandblasting, the robot drives the whole sandblasting device to move, the hair brush provides the sealing effect to conveniently form the negative pressure so as to prevent the abrasive material from leaking out, and under the action of the negative pressure, the abrasive material, the rust stain and the dust are completely recovered by the recovery pipe while the non-broken abrasive material can be recycled; the annular hair brush is connected to the body through the elastic connection sleeve with the folding part, such that the resistance of the weld reinforcement can be reduced, the continuity and the stability of the sandblasting canbe ensured, and the rust removing efficiency can be improved; with the sealing cover, the recovery of 98% of the abrasive material can be achieved, nearly 100% of the dust and the rust stain can be recovered, and the single rust-removing width is more than 200 mm; and the sealing cover has advantages of no dust pollution, high efficiency, environmental protection and low additional torque, can improve the load capacity of the robot body, and can increase the rust removing operation height of the robot.

Description

technical field [0001] The invention belongs to the technical field of painting and manufacturing of hull panels, and in particular relates to an environmentally friendly, efficient, and large-area automatic sandblasting and derusting sealing cover for all-round grinding and sandblasting of large joints on the hull surface. Background technique [0002] In shipbuilding, large-scale containers, electrical power stations and other equipment manufacturing sites, it is impossible to use large-scale sandblasting equipment such as sandblasting rooms for sandblasting and rust removal. At present, most of them use manual open sandblasting and rust removal. The labor intensity of workers is high and the working conditions are harsh. Its dust and noise have a great impact on human health. In addition, the dust after manual grinding has not been recycled, causing serious environmental pollution. In addition, the efficiency of manual sandblasting is low, and the effect of sandblasting a...
