[0002] Conventional gas cylinder paint pretreatment uses a lift to load and fix 10-20 gas cylinders in a mesh frame container, and then immerse the entire thing in the pretreatment process tank, according to the following process steps: loading → pre-degreasing → degreasing → water washing 1 → surface adjustment → phosphating → water washing → pure water washing → moisture drying → unloading; in the loading area, a group (10-20) of gas cylinders are placed in a special mesh frame (the end cover nut hole faces downward) and completely immersed in the tank liquid. The pretreatment solvent flows into the inner cavity of the gas cylinder through the gas cylinder body and the end cover nut hole. After the inner cavity is filled with the solvent, the pretreatment process begins → the lift is lifted, and the tank liquid is discharged from the drain valve hole and the end cover nut hole by gravity → moves to the next process tank → the lift descends → enters the next process tank, and so on.

[0003] The disadvantages of this transportation and loading method are: the inner cavity of the gas cylinder is not cleaned properly, different solvent tanks are easy to mix, the inner cavity phosphating effect is poor, and the inner cavity powder spraying quality of the gas cylinder is affected. For the pretreatment of the double-cavity gas cylinder, the upper gas chamber needs to be turned over and drained manually, which leads to a poor working environment and reduces production efficiency.

[0004] The existing paint standards for Dongfeng commercial vehicle carbon steel air cylinders are EQY-2 and QC-2. The salt spray resistance of the inner and outer surface paints is ≥480H and the aging resistance is ≥300H. In addition, the cleanliness and particle size of the inner cavity of the air cylinder is ≤0.8MM. The previous air cylinder paint pretreatment process is difficult to ensure the quality standard requirements of the inner cavity paint and the cleanliness and particle size of the inner cavity of the air cylinder.

The upper end of the cleaning liquid recovery pipeline is connected to the bottom of the supporting platform, and the lower end of the cleaning liquid recovery pipeline is connected to the cleaning liquid storage box.
