High pressure plate and frame filter press

1、 Equipment principle

The equipment combines mechanical pressure filtration and heat source drying into one, The sludge is pumped into the filter chamber through a plunger pump for preliminary filtration; Add a heat pump drying system to the equipment, equipped with a (vacuum) negative pressure suction device. After initial filtration, turn on the heat pump and vacuum suction device to destroy the sludge cell wall and dry the sludge. The filter plate is made of metal material, which is resistant to high temperature and high pressure and has a long service life. The filter plates are sealed with high temperature and high elasticity rubber. After initial feeding and filtration, the pressure can be increased by increasing the pressure(10Mpa)Further compress the space of the filter plate to achieve secondary mechanical dehydration.

2、 Equipment advantages

1. New technology

Combining the plate and frame filter press with the drying machine, the equipment occupies a small area, saves energy, and saves time.

2. Low operating costs

Just need to add conditioning agents, no need to add lime, reduce the boiling point of water through vacuum negative pressure, and save energy and high thermal efficiency in enclosed spaces.

3. Low moisture content in the discharged material

Feed concentration0.5%-10%The moisture content of the discharged material can be reduced to40%-45%.

4. High squeezing pressure

feed pressure1-2MpaThe secondary pressing pressure has reached8-10MpaThe secondary pressing of the filter plate results in uniform force distribution on the filter cake and stable sludge discharge.

5. High work efficiency

Short working cycle and production efficiency compared to traditional diaphragm filter presses4-6 times.
