Kind Code:
B2
Abstract:
To prevent early damage of filter cloth by keeping the optimum form of a filtration chamber without using a metallic spacer.
The filter frame 1 is disposed between filter plates 2, supported inside an outer frame 3, and made of a rubber sealing material of high hardness formed thick to protrude to both sides in the thickness direction of the outer frame 3. An inside circumferential cross section of the filter frame 1 is formed concave to enlarge a difference in curvatures before and after elastic deformation due to the compression in the thickness direction.
