Latest Patents

One of his latest patents is for a "Filter press with alternating diaphragm squeeze chamber plates and filtration chamber plates." This invention provides a method for separating solids from a slurry. The filter press consists of a series of plates that are held in a sealed and contacting relationship to form a plate stack. This stack includes alternating diaphragm-type squeeze plates and cloth-type chamber plates, creating filter chambers for effective slurry filtration. The diaphragm-type squeeze plates feature a thin liquid impermeable diaphragm, enhancing flexibility and heat transfer.

Another significant patent is the "Flow control sensor and method for filling of a filter press." This invention includes an air flow sensor that detects the slowing or intermittent stoppage of the feed pump. It signals a controller associated with a pressure regulator to increase the air pressure supplied to the feed pump. The air flow sensor comprises a spring-biased piston that moves within a housing, defining a flow passage and carrying a magnet. A switching device mounted on the housing detects the position of the piston magnet, ensuring efficient operation of the filter press.
