Sweeping device for steel plate pretreating line

Abstract

The invention discloses a sweeping device for a steel plate pretreating line. The device comprises a closed stripy box body which is mounted at an inlet end of a sweeping chamber, wherein brush hair is arranged on the lower end surface of the box body; an air pump is arranged at one side of the box body; the air pump is connected to the box body through an air inlet and can be used for supplying air into the box body; air outlet tubes which are distributed among the brush hair are distributed on the lower end surface of the box body; an air injecting port capable of injecting air to the surface of a steel plate is formed in the tail end of each air outlet tube. With the adoption of the device adopting the abovementioned structure, air can be injected during sweeping to completely clean theresidues and dust; the device is simple and ingenious in structure design, and high in use reliability; particularly the air outlet tubes can extend 5-10cm out of the box body, so that the air injecting ports can be fully close to the surface of the steel plate, and as a result, the cleaning effect is improved, and the energy conservation is saved; in addition, the air injecting ports face the outside of the sweeping chamber, so that the air injecting area is increased, and as a result, the sweeping 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 object of the present invention is to pro...
