Steel plate pretreatment line sweeping device

Abstract

The invention discloses a steel plate pretreatment line sweeping device. The steel plate pretreatment line sweeping device comprises a cleaning chamber and a conveying roller bed located in the cleaning chamber; an upper roller sweeping part and a lower roller sweeping part are arranged in the cleaning chamber, and penetrate the conveying roller bed in the transverse direction; a front upper gas blowing pipe is arranged in front of the upper roller sweeping part; a front lower gas blowing pipe is arranged in front of the lower roller sweeping part; an upper pushing roller and a lower pushing roller are further arranged in the cleaning chamber, and are located on the left side and the right side of the conveying roller bed; a rear upper gas blowing pipe is arranged behind the upper pushingroller; and a rear lower gas blowing pipe is arranged behind the lower pushing roller. After the above structure is adopted, gas blowing can be performed while the upper face of a steel plate is swept, the cleanness degree of the steel plate is greatly improved, and the sweeping effect is good; besides, an arranged driving structure can be used for adjusting the cleaning degree of the roller sweeping parts, and the requirements of different work conditions are met; and besides, the upper pushing roller and the lower pushing roller are matched with the upper roller sweeping part and the lower roller sweeping part so that the steel plate can be cleaned comprehensively, and the cleaning effect is further improved.

Description

technical field [0001] The invention relates to an auxiliary device for a steel plate pretreatment line, in particular to a cleaning device for a steel plate pretreatment line. Background technique [0002] The steel plate pretreatment production line achieves the purpose of high-efficiency continuous operation. During the steel plate pretreatment process, it often needs to go through steps such as preheating, shot blasting, cleaning, painting, and drying. Cleaning is an important process before painting. The quality of the quality directly determines the surface quality of the steel plate. Although the existing cleaning devices can clean the projectiles and residues on the surface of the steel plate to a certain extent, the cleanliness of the cleaning is relatively poor, and the cleaning effect is not very ideal. The structural design is relatively complicated and the equipment cost is high. Contents of the invention [0003] The technical problem to be solved by the inv...
