Damp cavity sealed type jogged dissepiment strainer plate and sealing method thereof

Abstract

The invention relates to a chimeric membrane filter plate with the damping sealing performance and a sealing method, a circle line hollow core boss of a membrane embedding part is embedded in a circle line sealing groove in the filter plate and sealed and matched with the circle line groove of the filter plate, one circle or a plurality of circles of lip edges at the bottom of the circle line hollow core boss sleeve in the membrane embedding part are embedded in the filter plate groove, one circle or a plurality of circles of lip edges and the groove surface of the filter plate groove form a self-sealing damping cavity or a linear sealing damping cavity, when the membrane is tympanic, the fluid enters the cavity body of the circle line hollow core boss sleeve by a plurality of fluid inletholes which are positioned around the root part of the hollow core boss sleeve, the fluid also enters the self-sealing damping cavity of the line sealing damping cavity from a plurality of fluid outlet holes which surround the cavity bottom of the self-sealing damping cavity or the linear sealing damping cavity along with the increase of the pressure of the fluid, the pressure of the fluid is directly acted on the lip edges, so as to force the lip edges and the groove surface of the filter plate groove to form the mandatory surface sealing or linear sealing.

Description

technical field [0001] The invention relates to a chiseled diaphragm filter plate with damping and sealing performance and a sealing method, mainly used for preparation of dyes, fillers, stearates, kaolin, coal ore, chemical industry, environmental protection, smelting, fruit juice, pectin, and medicines And other kinds of suspension dehydration, belonging to B01D25 / 12, B01D25 / 21 manufacturing field. Background technique [0002] The authorized announcement number is CN1232331C, and the name is "damping and sealing type embedded diaphragm filter plate and sealing method". Damping and sealing type embedded diaphragm filter plate, which includes a filter plate and a diaphragm, the upper part of the ring line inlay in the diaphragm has a ring line groove or is provided with a support bar in the ring line groove or not, and the ring line inlay in the diaphragm has a boss And one or more circles of lips, the diaphragm part adjacent to one or more circles of lips has a groove and...

AI Technical Summary

Problems solved by technology

The fly in the ointment is that although the ring groove on the upper part of the ring wire inlaid part in the diaphragm and the groove on the inlaid part in the filter plate form an open damping cavity, the outer wall of the wire groove on the upper ring of the ring wire inlaid part in the diaphragm The seal between the surface of the circular line groove in the filter plate still needs the action of external force, such as setting support bars in the circular line groove, etc., which cannot form a dynamic self-sealing structure
