A detailed introduction to the belt filter press plate

Belt filter plate with two kinds of septum welded to a hollow plate filter, thus forming a belt filter plate filter hollow structure, and the spacer surface of the outer surface of any have some indentation Space, too, creates a lot of blind spots on the same bottom so that the design is the same as the purpose of the vane filter plate, which is used to store and support the filter cake and create the necessary flow paths. While the other side of the plate and filter plate tightly connected to form a very good sealed space, this space as long as the design of a pipe connected to the outside world, used to send inflation (usually hydraulic oil) or exclude expansion.
When the internal expansion of belt filter plate increases, the expansion is to exert a pressure on the diaphragm, when the pressure is greater than the resistance of the filter on the diaphragm, the diaphragm will be outward convex, which resulted in Diaphragm filter press plate expansion deformation, and raised space can reduce the filter cake between the filter space, the final cake will be able to further filter out the level between the filter cake to achieve secondary squeeze dehydration, which Low cake moisture content.
Belt filter plate for expansion degree is to be limited, it is impossible to limit the material expansion, so belt filter plate on the extra out of a parameter, that is, belt filter plate expansion Parameters, this parameter will generally be between 1cm ~ 1.8cm, when this parameter is larger, the pressure on the filter cake is more obvious, then the filter cake sweat rate is lower. In general, the greater the number of expansion of the filter board will be larger, but always ensure that the range of 1.8cm below.
