Low price medicine used dedicated 50 square frame filter

Filtering mechanism filtering mechanism by the filter plate, filter box, filter cloth, squeezing the membrane composition, both sides of the filter plate covered by a cloth, you need to configure the press separator, a set of filter plate from the diaphragm plate and side components. Both sides of the diaphragm plate substrate coated with rubber membrane which is outside covered with cloth, filter plate side that is common. When the material from the orifice plate thrust into the respective filter chamber, solid particles larger than its diameter filter medium (cloth) are trapped in the filter pore size room, the liquid filtrate from the filter plate hole below the outflow. The filter cake was drained when needed, except that the membrane press, but also with compressed air or steam, from washing through the mouth, air rushed cake moisture, in order to reduce the moisture content of the cake. (1) filtering out of the way of clear filtrate flow filtration and undercurrent filter. A, Ming-flow filtration: nozzle mounted on a liquid water hole beneath each filter plate and the filtrate intuitive flow from the nozzle in the water. B, filtration undercurrent: the bottom of each filter plate has a fluid passage hole, several pieces of the filter plate was one of the fluid passage Kong Liancheng, a fluid conduit from the hole beneath the thrust plate is connected to a discharge. (2) Wash the cake needs washing, washing unidirectional and bidirectional flow sometimes washing, washing undercurrent unidirectional and bidirectional washing. A, a one-way free flow wash is wash lotion into the hole from the thrust plate in order to enter, through the filter cloth and then through the filter cake, nonporous filter plate outflow, then there is a liquid water nozzle orifice is closed state, no orifice of the nozzle is turned on liquid water. B, two-way free flow wash is wash lotion parties from both sides of the thrust plate into the wells were washed twice, namely lotions start again from the other side of the wash wash, lotion export with import is to diagonal direction, so called two-way cross-washing. C, undercurrent unidirectional flow wash is wash lotion into the hole from the thrust plate turn into the perforated plate, through the filter cloth and then through the filter cake, never well filter plate outflow. D, bi-directional undercurrent washing lotion wash lotion from both sides of the plate-side stopper into the hole twice, namely washing start washing the side, then the other side washing, export lotion is diagonal direction, so called undercurrent two-way cross-washing. (3) cloth: cloth filter media is a major, selection and use of filter cloth for filter effects have a decisive role, to use the appropriate filter cloth according to PH value of materials, solid particle size and other factors when selecting Material and aperture to ensure low cost and high filtration efficiency filters, when used, to ensure smooth cloth do not discount the aperture open. 4 frame filter
