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

Embodiment 1

[0011] Embodiment 1: with reference to attached Figure 1~3 . The damping and sealing type embedded diaphragm filter plate includes a filter plate 1 and a diaphragm 2, and the production of the filter plate 1 and the diaphragm 2 is a prior art, and will not be described here. The loop inlaid portion in the diaphragm 2 has a boss 4, the bottom of the boss 4 has one or more circles of lips 6, and the diaphragm portion adjacent to one or more circles of lips 6 has a groove 3 and is connected to one or more circles of lips 6 respectively. Ring lip 6 constitutes an open damping cavity 7, see attached figure 2 . The boss 4 is a hollow boss sleeve 5, and the hollow boss sleeve 5 surrounds the inlay part of the diaphragm. See attached figure 2 . Hollow boss cover 5 adopts prior art to make (as compression molding, molding welding molding etc.), do not describe here. There are a plurality of fluid inlet holes 8 around the root of the hollow boss sleeve 5, and a plurality of flu...

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the sealing method of the damping and sealing type fitted diaphragm filter plate, the ring line hollow boss sleeve of the diaphragm inlay part is embedded in the ring line sealing groove in the filter plate and is connected with the ring line of the filter plate The groove is sealed and matched. After one or more circles of lips at the bottom of the annular hollow boss sleeve in the diaphragm inlay part are embedded in the filter plate groove, one or more circles of lips form a self-sealing with the filter plate groove surface Damping cavity or line-sealed damping cavity, when the diaphragm is tympanic, the fluid enters the cavity of the ring-line hollow boss sleeve through multiple fluid inlet holes located at the root of the hollow boss sleeve, and as the fluid pressure increases, the fluid flows from Multiple fluid outlet holes around the bottom of the self-sealing damping chamber or line-sealing damping chamber enter the se...

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 inlet holes 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...
