Title: Method for discharging raw liquid remaining in raw liquid passing hole in filter plate type filter
Inventor: ITOU KIYOUJI
IPC: B01D25/12
Filed: 1980-12-19
Abstract: PURPOSE: To easily discharge a muddy raw liquid remaining in a raw liquid passing hole by a method wherein the muddy unfiltered raw liquid remaining in the raw liquid passing hole is dissolved in water by injecting water into the hole prior to discharging the raw liquid by compressed air or water.  
     CONSTITUTION: After closing a row of filter plates 1 the raw liquid is fed under pressure into the raw of liquid passing hole K by a pump P and is filtered in a filtration chamber A, at which time a cock 10 is closed. After filtration is completed, a cock 7 is changed over to communicate a feed pipe 6 with a discharge pipe 8. In this case, while filter cakes N in the chamber A are hard, the raw liquid in an upper layer in the hole K is naturally discharged into a tank T through pipes 6, 8 under the plate closing pressure of the filter plates 1, leaving a hollow space in the hole K. Then, the cock 10 is opened and water is injected under pressure into the hole K by a compressor 13, whereby the muddy raw of liquid S remaining in the hole K is washed into the tank T while being dissolved in water which is discharged into the tank T. Then, after completely pressure-feeding the water in a tank 11, compressed air is continuously fed under pressure so that the raw of liquid S dissolved in water in the hole K is  discharged into the tank T.
