PLATE-LIKE FILTER AND METHOD AND DEVICE FOR CLEANING FILTER FABRIC USED THEREIN

Japanese Patent JP3451551

B2

PROBLEM TO BE SOLVED: To stably produce dehydrated cake and prolong the service life of a filter fabric by cleaning all filter fabrics (all filtration chambers) at the same time while the dirty water generated by the cleaning is discharged by using an undiluted solution supply hole as a wastewater pipeline and particles adhered onto the surfaces of the filter fabrics are removed (the filter fabrics are made dust-free).
SOLUTION: A filter frame opening/closing means 5, which is used for superposing and separating all filter plates 1 by one stroke by pressing or drawing from one direction, and a cleaning nozzle driving means 12 are fit to a plate-like filter X so that a cleaning liquid injecting port 7 and an undiluted solution injecting port 8 are formed on one side of the filter X to form the upper and lower stages, the port 8 is connected to the undiluted solution supply hole 6 of the end filter plate 1 and a cleaning nozzle 10 from the port 7 can be detachably inserted into the hole 6 by one stroke. This filter fabric cleaning device has a dehydrated cake producing/separating mechanism and a filter cleaning/dirty water discharging mechanism to clean all filter fabrics 2 on all filter plates 1 at the same time, discharge the dirty water generated by the cleaning to the port 8 by using the hole 6 as the wastewater pipeline during the cleaning and recover the dirty water on the outside.
