Automatic sprinkling type phosphatization treatment system for surface of steel barrel

Abstract

The disclosed auto-spray phosphating system on steel barrel surface comprises an overhead ring tunnel with ports and ring gear chain device inside. Wherein, the said chain device comprises for work piece in turn an entrance area, a degrease area, a liquid regulating area, a cleaning area, a water regulating area, a phosphating area, a liquid regulating area, a cleaning area, a water regulating area (hole-form), a roasting area, and an exit area. The advantages of this invention include: saving space and energy consumption, convenient to clean precipitate, and cutting length.

Description

technical field [0001] The invention relates to an automatic spraying type phosphating treatment system on the surface of a steel drum. Background technique [0002] At present, the surface phosphating treatment system in the barrel making industry mostly adopts the following technical route: the workpiece is degreased through a degreasing agent on a straight-line assembly line, and then the workpiece is phosphated with a phosphating solution. After the completion, the hanging chain removes the workpiece from the closed It is taken out of the phosphating area and enters the baking furnace for drying, and the pretreatment process of the steel drum surface is completed. The above-mentioned system has the following disadvantages and deficiencies: (1) the existing technology is often an assembly line on the ground, which is not closed or semi-closed, occupies a large space, requires a length of more than 80 meters, high investment costs, long production cycles, and low productio...

Problems solved by technology

The above-mentioned system has the following disadvantages and deficiencies: (1) the existing technology is often an assembly line on the ground, which is not closed or semi-closed, occupies a large space, requires a length of more than 80 meters, high investment costs, long production cycles, and low production line efficiency; (2) ) The equipment is bulky, the process route is long, and the control program is complicated; (3) The labor intensity is high, and personnel inspections are often required. In case of unexpected shutdown, a large number of workpieces stagnant on the production line will be rusted on the surface, which seriously affects product quality; (4) ) The pipeline design is unreasonable and it is not convenient to clean the sediment in the pipeline; Roasting, the use of heat energy is not high, and the power consumption is large
