Fully Automatic Filter Press

The operation of conventional filter presses have always been messy and labor intensive. With ever increasing labor cost there arose a demand for atomizing several filter press operations. N.M. Patel Engg. was first to develop & offer automatic filter presses with following features. 

Auto Shaking mechanism 
The filter press with precisely engineered auto shaking mechanism will shake the group of plates at one time maintaining the predetermined gap between the two plates via chain or rope. The auto shaking mechanism is run by electric or hydro-motor shaking the plates with suitable revolutions adjusted by means of PLC, which co-relates the filtration sequence without operator’s attention.

AUTO PLATE SHIFTER FILTER PRESS
This highly advanced arrangement, provides fully automated closing and opening. When the filter is ready for cake dumping, the double acting cylinder retracts, pulling with it the movable head or follower. As soon as the followers is fully retracted, the shuttle shifter takes over, picking up the first plate from the head end of the unit, moving it across the opening or cleaning space to expose the cake and stacking it against the follower. The shifter then automatically reverses, returns for the next plate, transports and stacks it against the first plate and so on with time cycle set in PLC. Until all of the plates have been successively shifted and chambers dumped. An over-ride is provided so that the shifter can be stopped at any time and its motion resumed when the operator desired.

Drip Trays in Bombay Door Construction
Drip Trays are kept below the plates or Plate & Frame. It serves the purpose of collecting Drip (Filtrate) during the filtration or water during washing which falls due to capillary action from the Filter cloth.
Arranged underneath the filter plate set.
Fabricated of steel with plastic coating, stainless steel or entirely of synthetic material. Operated manually or fully automatic by means  of electro gear drive or hydro motor.

Accident Prevention  
As safety precaution for the operating personnel. Safety Light Curtain to interrupt operation with pull-cord in order to re-start the closing and plate shifting device.
