Abstract
A lightweight, substantially hollow filter plate constructed of foam molded thermoplastic material is formed by two separate identical plate sections each having a forward and rearward face. In a recessed type plate, the peripheral area of the rearward face of each section includes a plurality of support ribs arranged in lattice type configuration. In one embodiment the plate sections are integrally joined together with their rearward faces opposing each other and with the support ribs of one section butting against the opposing support ribs of the other section to produce a cellular construction light in weight but yet sufficiently strong to withstand the operating pressures normally associated with standard filter press machines.
Claims12
A thermoplastic filter plate for use in a filter machine used in separating solids from liquids, the plate comprising a first separate component having a forward face including a filtrate drainage surface and a rearward face including means to provide support ribs;
- a second separate component which is substantially identical to said first component;
- and means to join said first and second components with their rearward faces opposing each other in mirror image fashion so that the support ribs of said first component operatively oppose the support ribs of said second component to provide a plate of minimum weight and sufficient strength.
A thermoplastic filter plate for use in a filter machine used in separating solids from liquids, the plate comprising a first separate component having a forward face including a filtrate drainage surface and a rearward face including means to provide support ribs;
- a second separate component which is substantially similar to said first component;
- and means to join said first and second components with their rearward faces opposing each other so that the support ribs of said first component operatively cooperate with the support ribs of said second component to provide a plate of minimum weight and sufficient strength.
