retractable filter

working principle:

The filtrate is pumped into the filter chamber from above, flows through the filter fleece into the bottom chamber and finally into the filtrate tank. The particles are retained by the filter fleece and build a filter cake. With the increasing filter cake the flow-through resistance raises as well as the pressure inside the filter chamber. As soon as the discharge pressure is reached, the inflow is closed the filter chamber charged with compressed air. For this reason the remaining fluid is pressed through filter cake and fleece (the sludge is dried). Now the two end end-baffles are opened and the lifting bars (laterally fleece packing) destressed, fleece and filter cake are extracted from the filter chamber and the filter cake is stripped of.

design:

The filter is a rectangle container made of steel. It consists of a top and a bottom chamber. The top chamber is lifted up during the regeneration period what makes the removal of the filter cake possible. As support for the filter fleece, several horizontal slot sieves are instlled. The pressure stability is achieved with the help of outer bracing profiles. The caulking between top and bottom chamber is managed with a sealing tape which is fastened at the top chamber.

optional features:

The pressure belt filter is available with endless filter belt and with filter fleece as consumption material. Dependent Dependend on the application varying materials and grades of filtration are available. On demand the use of filter aids is possible. For special applications a model made of stainless steel and special sealing material is possible.
