ABSTRACT:
An improved stock washer for removing impurities from a porous mat disposed over a vacuum head is disclosed. In one application in connection with an industrial paper making process, paper pulp forms a porous mat over a rotating drum which has a vacuum on the inside. The washer includes an elongate housing, defining a chamber therein, disposed above the drum with a slot along its bottom and resilient, downwardly-extending wipers at the slot edges, Water flows into a pipe extending the length of the chamber. The pipe has holes along its sides to direct water into the chamber downwardly and outwardly. The pipe, which extends through the ends of the housing, is mounted to adjustable mounts at both ends to allow the washer height above the mat to be adjusted. Water flows through the holes in the pipe and accumulates at the chamber bottom where it is directed into the mat by the resilient wipers. The water flows through the mat into the drum displacing chemical impurities in the process. The wipers can be attached at an angle relative to the washer so that the washer may be placed other than centered directly above the drum while the chamber remains vertical, thus allowing a number of spaced apart washers to be used. A bracketing mechanism is also disclosed which allows the wipers to be easily attached to the washer.
