METHOD OF AUTOMATIC CONTROL OVER FILTER PRESS AND DEVICE TO THIS END Russian patent published in 2014 - IPC B01D37/04 B01D25/12 

FIELD: process engineering.

SUBSTANCE: proposed method comprises determination of filtration termination by measurement of pressure acting on pressure transducer sensor from the side of filtration surface of at least one filtration plate to define filtration termination moment depending upon said measured magnitude. Plat to this end comprises filter press with the stack of filter plates adjoining on one side the filter press front support and, on opposite side, the pressure plate. Said plates are provided with suspension feed and filtrate discharge pipes equipped with shutoff valves. It comprises control program device, process parameters transducers and actuators, computer to process pressure parameters, parameter setter to define filtration termination. One of said filtration plates is equipped with pressure transducer including sensor arranged on plate filtration side and signal converter.

EFFECT: comprehensive control over precipitate formation, minimum costs for implementation.
