Definitions
- the present invention relates to an arrangement of a filter plate for a filter press and a sealing device.
- the filter plate has a contact surface for abutment with another filter plate which extends parallel to a plane formed by the filter plate.
- the filter plate has at least one channel opening for forming a channel, wherein the channel opening is perpendicular to that of the filter plate formed level passes through the filter plate and is limited by a channel surface of the filter plate.
- the invention relates to a filter plate.
- a filter pack for a filter press which consists of several pairs of juxtaposed filter plates. Between the filter plates each filter chambers are formed.
- the filter plates have for this purpose a central filter surface and a central filter surface framing thicker sealing edge. In the filter press, the filter plates can be moved away from one another and towards one another, whereby the filter chambers can be opened and closed.
- Each filter chamber usually has at least one inlet channel and an outlet channel.
- the suspension to be filtered which is also referred to as turbidity, flows into the filter chamber via the inlet.
- the suspension is then filtered by means of a filter cloth, whereby the solids are retained by the filter cloth in the filter chamber, so that a so-called filter cake is formed.
- the filtrate freed from the solids is led out of the filter chamber via the drainage channel.
- WO 2004/043569 A2 discloses a membrane filter press in which a plurality of membrane filter plates and membrane-free filter plates arranged therebetween are arranged side by side.
- the filter plates are clamped in the operating state between a head and an end piece and are designed so that between them a filter chamber is arranged.
- On the outside a thicker sealing edge is formed in each case at the filter plate, with adjoining filter plates lying against one another.
- a filtrate channel is formed in the corner region of the filter plate.
- channel openings are provided in adjacent filter plates in the region of the sealing edge which form aligned channel surfaces.
- a filter cloth Radially inside of the filtrate channel, a filter cloth is attached, which extends into the filter chamber.
- the edge region of the filter plate which surrounds the filtrate channel, has an annular, dovetail-shaped groove in cross section, in which a sealing ring rests for sealing the filtrate channel.
- the inlet channel formed by adjacent filter plates may also be sealed.
- the present invention is therefore based on the object to provide an arrangement of a filter plate for a filter press and a sealing device and a filter plate, which does not damage the filter plate in the field of sealing a channel formed by a plurality of filter plates in operation in a filter press.
- the inventive arrangement is characterized in that the filter plate at the transition from the channel surface to the contact surface has an annular recess with a first annular boundary surface and the sealing device has an elastic ring seal and a clamping ring.
- the elastic ring seal on a second annular boundary surface, which corresponds to the first annular boundary surface.
- the clamping ring is formed so that it is insertable into the annular recess, that the elastic ring seal between the clamping ring and the first annular boundary surface of the filter plate is clamped.
- the sealing device of the arrangement according to the invention has the advantage that no solids can penetrate between a groove and a seal.
- the clamping ring presses the elastic ring seal against the first annular boundary surface of the filter plate and clamps it so that no solids can penetrate in the region between the clamping ring and the first annular boundary surface of the filter plate.
- this does not lead to a break of the filter plate in the environment even at high temperatures the channel surface.
- no fragile projection is formed between a groove and the channel opening.
- the arrangement according to the invention has the advantage that both the clamping ring and the elastic ring seal can be replaced. Therefore, all boundary surfaces between the clamping ring, the ring seal and the filter plate can be cleaned.
- different clamping rings can be used.
- the material of the clamping ring can be adapted to the use of the filter plate in the filter press.
- the pressure with which a suspension is introduced into the channel can be taken into account.
- the temperatures occurring and the solids occurring in the suspension can be taken into account in terms of type and size in the appropriate choice of the clamping ring and also in the choice of elastic ring seal.
- the first annular boundary surface has a first partial surface which runs parallel to the plane formed by the filter plate. Furthermore, the first annular boundary surface has a second partial surface which is perpendicular to the plane formed by the filter plate.
- the recess is thus substantially rectangular, in particular square.
- the annular edge which is normally formed between these two surfaces, is cut out by a rectangular, in particular rectangular recess, which is rectangular in cross-section. In this way, the annular recess with the rectangular or square cross section is formed.
- this recess for a seal between adjacent filter plates.
- the elastic ring seal can in fact be clamped into the recess by means of the clamping ring.
- a groove is formed in the second partial surface, which extends into the filter plate.
- a corresponding rib is formed, which engages in the groove in order to hold the elastic ring seal in the recess in the axial direction of the channel opening, that is to say in a direction perpendicular to the plane formed by the filter plate.
- The- se groove differs from a conventional dovetail groove. It can have a much smaller depth, since in the recess, further boundary surfaces for the installation of the elastic ring seal on the filter plate are also provided outside the groove.
- the groove should secure the elastic ring seal only against movement in the axial direction.
- the groove is arranged so that the entry into the groove has no joint at the contact surface, so that there is no risk that solid particles can penetrate into the groove, for example, a suspension supplied under pressure.
- the groove is oriented in the direction of its depth parallel to the abutment surface, that is to say parallel to the plane formed by the filter plate, and not, as in the case of a conventional groove for a sealing ring, perpendicular to the abutment surface.
- the elastic ring seal on a third annular boundary surface with first locking means.
- the third annular boundary surface is disposed away from the second annular boundary surface.
- the clamping ring on a fourth annular boundary surface with second locking means.
- the fourth annular boundary surface of the third annular boundary surface of the elastic ring seal facing.
- the fourth annular boundary surface corresponds in particular to the third annular boundary surface.
- the geometry of the boundary surface of the ring seal, which faces the clamping ring thus corresponds to the geometry of the boundary surface of the clamping ring, which faces the boundary surface of the ring seal.
- the clamping ring can clamp the elastic ring seal in such a way that the ring seal can exert a sealing effect on the contact surface for engagement with another filter plate.
- the sealing device is coupled to the filter plate so that there is no risk of breakage of the filter plate.
- the third annular boundary surface of the elastic ring seal has in particular a third partial surface, which is aligned perpendicular to the plane formed by the filter plate.
- the first locking means of the ring seal preferably have latching noses which are formed in the third partial surface and which hold the clamping ring in the axial direction of the channel opening in the recess.
- the elastic ring seal is thus held by the rib engaging in the groove of the filter plate in the axial direction in the filter plate, and the clamping ring is held in the filter plate in the axial direction by the latching lugs of the ring seal. In this way, the clamping ring with the ring seal can be securely held in the recess, wherein it is still possible to replace both the clamping ring and the ring seal.
- the third annular boundary surface of the elastic ring seal on a fourth part surface, which is aligned parallel to the plane formed by the filter plate. at the fourth part surface may have the first locking means teeth. These teeth allow a particularly good sealing effect at the interface with the clamping ring. In the area of the teeth, the clamping ring can also have corresponding teeth. However, this is not necessary. The clamping ring can also have a flat partial surface in this area.
- the elastic ring seal accommodated in the recess projects beyond the contact surface of the filter surface with a sealing projection.
- this Dichtvor- jump is pressed against the sealing edge of the adjacent filter plate, whereby the channel formed by the channel openings Ka is sealed to the contact surfaces between two filter plates.
- an end face of the elastic ring seal received in the recess and a side face of the clamping ring can be aligned with the channel surface.
- the channel surface of the filter plate can thus be continued through the end face of the ring seal and the side surface of the clamping ring, without projections in the channel formed by the channel surface are gebil det. In this way, it is advantageously prevented that solids of the liquid guided by the channel, that is to say in particular solids of a supplied suspension, get caught on projections of the channel.
- the channel opening of the filter plate is in particular part of an inlet and / or outlet channel.
- the suspension to be filtered is fed to a filter chamber which is formed between two filter plates.
- the filtrate is led out of the filter plate via the discharge channel.
- the ring seal may in particular consist of an elastomer.
- the clamping ring is in particular rigid. It can consist of a plastic or a metal, in particular of steel.
- the material of the ring seal and the clamping ring can be adapted to the use of the filter plate in the filter press to suitably seal the channel.
- a filter cloth is attached to the filter plate or clamped between two filter plates.
- the filter cloth does not cover the contact surface of the filter plate, which is formed at the sealing edge of the filter plate.
- the filter cloth thus also does not cover the area of the contact surface which surrounds the channel opening.
- the invention further relates to a filter plate for a filter press with a contact surface for abutment with another filter plate, which is parallel to a plane formed by the filter plate extends.
- the filter plate has at least one channel opening for forming a channel, where at the channel opening perpendicular to the plane formed by the filter plate passes through the filter plate and is delimited by a channel surface of the filter plate.
- the filter plate at the transition from the channel surface to the contact surface on an annular recess with a first annular boundary surface.
- the filter plate according to the invention can be used in particular with a sealing device, as described above.
- the filter plate thus has the same advantages as the inventive arrangement.
- the first annular boundary surface of the filter plate has, in particular, a first partial area which runs parallel to the plane formed by the filter plate. Furthermore, it has a second partial surface, which runs perpendicular to the plane formed by the filter plate.
- the recess thus has a rectangular, in particular square cross-section. It is introduced at the edge, which forms the transition from the channel surface to the contact surface without the recess.
- a groove is formed in the second partial surface, which extends into the filter plate.
- the direction of the depth of the groove is aligned in particular parallel to the contact surface.
- an incision is formed in the second part surface at the transition to the abutment surface.
- This incision is square, in particular in cross section.
