Large-scale plate shot-blasting and cleaning device

Abstract

The present invention discloses a large-scale plate shot-blasting and cleaning device, and belongs to the technical field of the shot-blasting treatment. The device mainly solves the problems in the prior art that burrs, rusty spots, scales and other attachments on the surface of a plate are low in cleaning efficiency and the surface of the plate is poor in quality. The device mainly comprises a shot-blasting unit, a shot-blasting chamber, a shot collecting pool, a helical conveyor, a feeding mechanism, and connection ports. The feeding mechanism comprises a base, a motor, a power roller bed, a positioning roller bed, a supporting roller bed and a sprocket-drive device. The connection ports comprise a de-dusting and air-draft connection port and a shot-separating connection port. A large-scale plate is slowly fed into the shot-blasting chamber through the feeding mechanism, and is blasted by shots launched by the shot-blasting unit at a high speed. Therefore, the shot-blasting and cleaning operation on the large-scale plate is completed. According to the invention, the shot-blasting operation can be conducted on the two sides of the plate at the same time, so that the device is high in working efficiency and good in cleaning effect. Meanwhile, the surface quality of the plate is greatly improved, so that the later surface protection and life prolongation of the plate can be facilitated. The labor intensity of workers is lightened, and the working environment of workers is improved.

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 large-scale sheet metal shot blasting cleaning device. Background technique [0002] Large sheet metal is one of the most demanded raw materials in the equipment manufacturing industry. Basically, it is provided by the steel mill. During the forming process of the sheet, it is easy to form a layer of oxide scale on its surface, but in the later use, it needs to be cleaned and the internal quality of the sheet cannot be reduced, otherwise it will affect the use. [0003] Due to the long-term storage of the sheet, rust spots and other phenomena will appear on the surface. If it is not cleaned and protected in time, loose and porous rust spots will absorb water in a humid environment, which will accelerate the rate of oxidation and corrosion, which will not only cause waste of materials, but also reduce the quality of the shee...
