What is the operating flow of the belt vacuum filter?

One: vacuum belt filter before the start of the work
1, check the vacuum belt filter parts meet the installation requirements, the connection is loose, whether the increase in the lubricant parts;
2, check the vacuum belt filter on whether there is foreign matter, especially the vacuum chamber, filter bags with or without obstacles and obstacles;
3, check the input power supply voltage is normal, whether the power supply is connected to the zero line (ground), water pressure is greater than 0.3Mpa;
4, check the reducer oil mist is added to the oil, whether the oil reached the oil level line
Two: vacuum belt filter boot.
1, start the vacuum belt filter air compressor, open the gas source switch, adjust the pressure regulator input pressure to meet the following requirements; main cylinder pressure: 0.4 ~ 0.5 Mpa; switching valve pressure: 0.3 ~ 0.4 Mpa; deviation airbag pressure: 0.15 ~ 0.2 Mpa;
2, turn on the main power switch, start the main motor button, adjust the inverter **, to determine the vacuum belt filter running speed
3, start the vacuum pump, open the vacuum valve, vacuum pump inlet size in line with the requirements of the vacuum pump instructions.
4, followed by opening the filter belt reclaimed water, lubricating sealing water, to meet the following requirements: filter bag recycled water pressure:> 0.3Mpa.
5, start the brush roller motor, adjust the filter with recycled water spray direction, so that it reaches the spray effect.
6, observe the operation of the filter belt, adjust the filter belt correction switch, so that the filter belt is running normally.
7, open the exchange tank control valve, from small to large regulation of feed flow, to achieve operational requirements. When the cake is to the outlet, record the vacuum table vacuum
8, open the eluent switch, adjust the eluent flow, record the switch position.
9, the appropriate adjustment of feed flow, equipment operating speed, eluent flow, so that filtration and filtration requirements to meet the technological requirements.
10, check the vacuum belt filter belt tension effect and filter belt deviation, record deviation.
11, record the feed valve, filter with recycled water valve opening position and the frequency of the inverter.
Three: vacuum belt filter shutdown
1, close the slurry control valve, to be filtered to the remaining filter cake unloading so far.
2, filter cake unloading net, the filter belt cleaning 1 to 2 weeks, followed by closing the eluent valve → brush roller motor switch → filter bag recycling water valve → vacuum pump switch → host power switch → total gas switch → air pump switch → open Air pump valve.
Four: vacuum belt filter maintenance
1, strict transfer procedures, vacuum belt filter before the boot should be running for 5 minutes to determine whether the device is in a normal state.
2, in strict accordance with the operating procedures, not free to change the inverter function.
3, vacuum belt filter failure can not meet the technical requirements, should be shut down maintenance, is strictly prohibited disease work.
4, electricity, gas control cabinet to keep dry and clean, not to place foreign objects and tools.
5, gas water separator in the liquid shall not exceed the cup of the scale line.
6, the workplace to keep clean, clean, clean the ground and equipment to prevent water and material splash in the motor, electronic control components, correction switch.
7, vacuum belt filter filter to keep clean, to prevent welding slag and foreign body damage filter belt.
8, often check the vacuum belt filter to replace the wearing parts, to ensure the normal operation of equipment.
9, all the rotating roller bearing grease time does not exceed 3600 hours, reducer oil change time does not exceed 7200 hours.
10, inverter, reducer, vacuum pump, filter belt maintenance are according to their factory instructions.
