Description

1 General

1.1 Overview

200L steel barrel spray painting and baking equipment mainly spray and dry the surface of 200L steel barrel.

The coating quality of the steel drum after spray-painting and drying complies with GB / T325.1 Packaging Container Steel Drum Part 1: General Technical Conditions.

1.2 Construction conditions

1.2.1 Equipment installation location

The height of the eaves of the factory building where the 200L steel barrel spray painting and Drying oven equipment is installed is not less than 5.5 meters. If driving is considered in the factory building, the exhaust duct must protrude laterally from the window or wall, and cannot be emptied directly upward. Above the pipeline, that is: 6.5 meters above the ground, the height of the factory eaves is determined according to the installation height of the vehicle

1.2.2 Power supply: 380V ± 10%, 50Hz (-0.1 ~ + 0.5)

220V ± 10%, 50Hz (-0.1 ~ + 0.5)

1.2.3 Compressed air

1) Purity

Solid particles: up to 0.5g / Nm3

Particle diameter: 10μm ~ 15μm

Oil content: <0.01mg / Nm3

Pressure: 0.5Mpa ~ 0.8Mpa

2) Dew point: 15 ° C (under standard atmospheric pressure)

3) Temperature: ambient temperature

1.2.4 Environmental conditions in the plant
Temperature: 0 ~ 40 ℃

Relative humidity: ≤80%

1.2.5 Water supply conditions: tap water

2.Technical conditions

2.1 Composition and process flow:

Composition of 200L steel barrel spray painting and baking equipment: spray booth body, spray step conveyor, four chuck rotary machine, lifting rotary machine, paint spraying waste device, spray paint supply system, front conveying device, front transmission device, drying room body, Front exhaust device, heating system, rear exhaust device, isobaric supply and hot air circulation system, cooling system, rear transmission device, rear conveying device, electrical control system, exhaust duct, etc.

After the drum is taken off the line from the barrel making equipment, it is turned into a vertical conveyance by a turning machine. Through the vertical conveying of the roller, the stepping conveying device of the spray booth is carried out by the lifting and skipping chain. The rollers are vertically conveyed into the front distribution device, and the steel drums are conveyed to the conveying chain of the drying room through the function of the front-drive to lift and jump the chains. The chains are conveyed into the curing oven for baking and cooling. Under the action of chain skipping, it can be distributed to the rear roller conveyor delivery line, or it can be automatically transferred to the warehouse (customized according to customer requirements).
