Shot-blast cleaning device for outer wall of wind power tower drum

Abstract

The invention discloses a shot-blast cleaning device for the outer wall of a wind power tower drum, and belongs to the technical field of shot-blast treatment. The shot-blast cleaning device is mainly used for shot-blast treatment of the outer wall of the wind power tower drum and solves the problems of relatively low efficiency in cleaning rust, welding slag and other attachments on the outer wall of the wind power tower drum and stress concentration caused in the reeling process of the tower drum. The shot-blast cleaning device comprises a shot-blasting device, a shot-blasting room, a shot-collecting pool, a spiral conveying device, a load bearing vehicle and connecting openings. A motor provides power, the tower drum slowly moves and rotates at a low speed around the axis per se, shots blasted by the shot-blasting device continually impact the moving tower drum to finish shot-blast treatment, and scattered shots and generated dust are conveyed to other equipment connected with the connecting openings to be effectively processed. The shot-blast cleaning device for the outer wall of the wind power tower drum is high in cleaning efficiency and automation degree, low in dust pollution and improved in surface quality, reduces stress concentration, relieves the labor intensity of workers and improves the work environment of the workers.

Description

technical field [0001] The invention belongs to the technical field of shot blasting, and relates to a shot blasting cleaning device, in particular to a shot blasting cleaning device for the outer wall of a wind power tower tube. Background technique [0002] Shot blasting technology is a very effective method in surface treatment technology. Shot blasting is to use the centrifugal force of the impeller on the throwing head when it rotates at high speed, to shoot the abrasive to the surface of the component to be processed at a high linear speed, to produce impact and grinding, to remove the welding slag and rust on the surface of the component, and A certain roughness is produced, which reduces the stress concentration to a certain extent. [0003] The wind power tower is an important load-bearing component of wind power generation equipment. The outer diameter of the tower is relatively large and the diameter changes. It is rolled and welded by sheet metal during the manu...
