Water easily enters flow channel for liquids by this passage through filter cloth, aperture, and this stage is the packing stage of power, the rightest toggle link, three
Gusset, left toggle link are under " stretching " state, and the enlarge-effect of extruding force drive system power is maximum, the pressure suffered by mud
Power is the most maximum, carries out pressurize certain time, is constantly extruded by moisture in mud, until not having moisture to extrude, and filter pressing
Stop.Discharging flashboard is opened, and mud discharges filter pressing chamber under gravity.The moisture being press-filtered out is by filter cloth, the fixing end
Aperture on plate enters into fluid passage, and under check valve effect, this liquid can only be from the unidirectional discharge of discharging tube.Through one section
After time is run, such as the mud granule mesh by filter cloth or the aperture clogs of fixed plate, now open high-pressure air source and air inlet
The controlled valve of pipe is opened, and the controlled valve at drain pipe is closed, and gases at high pressure will block on filter cloth and on bottom plate aperture
