- Description of cleaning unit
The cleaning system consists of high-pressure cleaning box, low-pressure cleaning box, squeezer device, brush roller device, edge blowing device, filtration system and water circulation system.The water tank and pump body are made of stainless steel.
The cots in cleaning are double outlets, and the upper and lower rollers are interchangeable. The coupling, reducer and motor use the same model to ensure interchangeability.
During cleaning, both the extruder roller and the supporting roller are coated with polyurethane, with a thickness of 15mm and a hardness of Shore 75-80.
Cleaning process description, plate strip after high-pressure cleaning entry pinch roll roller gear box for points and synchronous transmission, with frequency conversion motor) drawing into the high pressure cleaning tank, after the first group, the second group of low pre cleaning cleaning nozzle, pressure is 0.4 to 0.6 mpa, and the third group of nozzle of high pressure flushing after (pressure is 2 to 3.5 mpa) into the next board face scrub brush roller (roller diameter Φ 240 x 1850 mm), brush roller equipped with belt drive above the support roller (roller diameter Φ 250 x 1850 mm), then enter the name of the second high pressure flushing (pressure is 2 to 3.5 mpa), the sheet surface to wash up and down.And then enter the group to scrub on the strip board face scrub on roller (roller diameter for Φ 240 x 1850 mm), brush roller equipped with belt drive above the support roller (roller diameter Φ 250 x 1850 mm) : after completion on board face scrub after five low pressure flush into the high pressure outlet drain roller (roller diameter for 250 x 1850 mm Φ, roller gear box for points and synchronous transmission, with frequency conversion motor) to remove surface residual cleaning fluid, high pressure cleaning section.
After the high-pressure cleaning section is completed, the plates enter the low-pressure cleaning chamber.After three group of low pressure water spray pipe, pressure is 0.4 to 0.6 mpa, and then into the last set of spray pipe to rinse of plank, into the drain in the cabinet after the completion of roller (roller diameter for 300 x 1850 mm Φ, roller gear box for points and synchronous transmission, with frequency conversion motor), the drain in the cabinet, will most of the residual night stand in the casing, the squeeze roller in the cabinet equipped with edge blowing device to prevent plate edges on both sides with the problem of water, into the box after outside drain (300 x 1850 mm roller diameter for Φ, roller gear box for points and synchronous transmission, with frequency conversion motor), the surface residual water drain,Flanging devices (manual opening and closing) are provided on both sides of the extruding roller to prevent the problem of water on the edge of plate.Low pressure cleaning section is completed.
After the low-pressure cleaning is completed, it enters into the drying system, which is composed of drying box body, heater box body, centrifugal fan and connecting pipe.Dry the surface and clean the system.
3.1 High pressure cleaning section
