Movable-type spraying dust removal system for long rod piece

Abstract

The invention relates to a movable-type spraying dust removal system for a long rod piece. The movable-type spraying dust removal system comprises a working table, a dust sucking box, a flexible rubber pad, an air channel and at least two pressing guide rollers. A rotary table support is arranged at the left end of the working table, and a tip support is arranged at the right end of the working table. The rotary table support is provided with a main speed adjusting motor and a chuck. The tip support is provided with a movable tip and an air cylinder. The air channel is provided with a grid andan air exhaust opening, the dust sucking box is arranged above the grid, the lower portion of the dust sucking box is open, and the dust sucking box comprises a box body and a dust collecting hood. The grid and the dust sucking box are covered with the flexible rubber pad, and the two ends of the flexible rubber pad are fixed. According to the movable-type spraying dust removal system, a large fixed-type air suction opening is changed into a movable-type air suction opening moving synchronously with a spray gun, thus the opening diameter of the air suction opening is decreased greatly, the air suction motor power needed is reduced greatly in the case of the same negative pressure, thus equipment investment and electric energy consumption are remarkably reduced, and positive technical significance is achieved.

Description

technical field [0001] The invention relates to a mobile spraying dust removal system for long rods, belonging to the technical field of material surface treatment. Background technique [0002] At present, in the machinery and energy industries, a large number of long rods that require wear resistance and anti-corrosion are used; when manufacturing such long rods, a dense high-hardness coating generally needs to be prepared on the surface. It is a common method to prepare this coating on the surface of parts by thermal spraying technology. During the spraying process, a large amount of smoke and dust will be generated. These smoke and dust must be treated by the exhaust and dust removal system to meet the safety emission standards. Because the length of these long poles is long, the length of some long poles even exceeds 10 meters, in order to coat the surface of the poles with coating, the spray gun also needs to move a long distance during spraying. In the prior art, the...
