Definitions

the subject invention relates to a sifting for a papermaking plant consisting of a support bar and attached to this, to each other subsequent plates of a ceramic material, wherein the Carrying rail and the plates of ceramic material to the adjacent Surfaces are formed with mutually facing recesses, in which fasteners are anchored.
the subject invention is therefore the object of a To create a sill through which the known prior art Adhesive disadvantages are avoided.
This is inventively characterized achieved that the connecting elements in the recesses of the plates made of ceramic material are fixed by positive engagement and that side by side located plates by means of at least one over the butt joint extending, common Kauselmentes on the support bar are attached.
the recesses located in the plates are with undercuts formed, which are engaged behind by the connecting elements are.
the recesses provided in the plates are by at least one extending in the longitudinal direction of the support bar Groove formed.
each connecting element is formed by a strip, which in the region assigned to a recess of the plates has a cross-section which is diametrically opposite to the cross-section of the recess.
the strip-shaped connecting element may be divided in its longitudinal direction into at least two wedge-shaped element pieces.
each connecting element may be formed as a cone body, which is formed in the area associated with a recess in a plate area with diametrically disposed flats, and it may also be formed with a transverse to the flats slot.
each connecting element may be formed with a ring-running collar, which comes to rest on the surface of the plate.
each connecting element on the end face associated with the support bar with an actuating slot or the like.
the connecting element is designed as a trapezoidal spring body which is elastically deformable in its region assigned to a recess in a plate.
each connecting element may be formed as a cone-shaped body, which is formed slotted in its part facing the plate and which is provided with an axial bore into which a screw can be screwed, whereby the two parts separated by a slot are radially apart adjustable.
the connecting element formed by a bracket, which with two semi-annular, through a slot separate bracket parts is formed, wherein in the plates provided grooves have an approximately circular cross-section.
the grooves of the plates bracket parts Fixed in position by means of a potting compound.
FIGS. 1 and 1a screening strip for papermaking plants consists of a support strip 1, at the top over the entire length of plates 2 are fixed from ceramic material.
the support strip 1 is formed over its entire length with a groove 10, by means of which it can be fastened to a support frame and relative to this transversely to the direction of movement of the wire belt of the papermaking plant.
the support bar 1 is formed with two equally extending over its entire length grooves 11.
the plates 2 made of ceramic material on its underside with extending over the entire length of grooves 21 are formed.
the grooves 11 and 21 serve to receive fastening elements 3 for the attachment of the plates 2 made of ceramic material to the support strip. 1
the connecting elements 3 are arranged so that they extend over the joint between two adjacent plates 2 of ceramic material.
the support bar 1 and the connecting elements 3 are made of steel, of a hard plastic material, such as polyethylene, glass fiber reinforced plastic, carbon fibers or the like. Materials made. The choice of material for the support strips and the connecting elements is known from the prior art. 2, 2a to 2c, a first type of connecting elements 3 is explained. As can be seen from Fig.2, the grooves 21 provided in the plates 2 are undercut. As can be further seen from Figs.2a to 2c, each connecting element 3 is formed in its upper portion with a broadening, whereby it is adapted to the cross section of the grooves 21 of the plates 2. In order to push the connecting elements 3 in the grooves 21 and to lock in these, they are divided along a vertical plane into two wedge-shaped components 31 and 32.
the connecting elements 3 are formed with laterally projecting ribs 33.
the attachment of the connecting elements 3 in the grooves 21 of the plates 2 takes place in that they are inserted into these from their end faces. Since the upper portion of the connecting elements 2 has a groove 21 opposite cross-section, the connecting elements are rigidly fixed in the grooves 21 by positive engagement.
the attachment of the connecting elements 3 in the grooves 11 of the support strips 1 is effected by introducing a plastic potting compound 4. Due to the positive connection of the plates 2 with the connecting elements 3, this has the desired rigidity. Furthermore, since the connecting elements 3 extend over the butt joints located between two plates 2, the adjacent plates 2 are rigidly fixed to one another, with their abutting edges being at the same height.
FIG.3, 3a to 3d is a second embodiment of a connecting element shown.
This connecting element consists of a conical pin 5, which over part of its height with a Slit 51 and formed with two diametrically opposed flats 52 is. Furthermore, he has a curved head 54 at its tapered end with actuating slots 55.
This connecting element 5 can due to the flattening 52 in the undercut Grooves 21 of the plates 2 are used. By its rotation by 90 ° whose conical surfaces 53 come to the side walls of the Grooves 21 to the plant and are due to the achieved by the slot 51 Elasticity locked with these form-fitting.
these connecting elements 5 also become used in the region of the impact in two adjacent plates 2, whereby they are rigidly attached to each other.
the connecting element 5a shown in FIGS. 4, 4a to 4d differs from the pin 5 according to the 3a to 3d only in that he with a annular collar 57 is formed, which at the bottom of the Plates 2 comes to the plant.
the connecting element shown in Figures 5, 5a and 5b is also formed by a conical pin 6, which with a central bore 61 and formed with a slot 62, wherein the central bore 61 is assigned a screw 63.
the screw 63 By screwing in the screw 63 are the two the grooves 21 associated wings of the pin 6 apart moves, whereby it locks in the grooves 21 by positive engagement become.
the connecting element shown in Figures 6 and 6a consists of a approximately V-shaped spring 7, the two legs 72 to the two side walls the grooves 21 come form-fitting to the plant.
the connecting element 8 shown in Figures 7 and 7a consists of a keyhole-shaped bracket 8, which with two legs 81 and 82nd is formed, which is inserted into the grooves 11 of the support strip 1 and by means the potting compound 4 are attached. Close to the legs 81 and 82 semi-annular strap parts 83 and 84, which through a slot 85 from each other are separated. Through the slot 85, the bracket 8, the required Elasticity to be inserted into the annular grooves 21 of the plates 2 to become. Since the grooves 21 a corresponding, approximately annular Have cross-section, this is also a positive locking the bracket 8 with the plates 2. Finally, in the grooves 11 and 21 remaining space filled by a plastic mass 4a, thereby the bracket 8 are fixed in position.
connecting elements extend beyond the butt joint between two plates 2, whereby they are held in their mutual position.
the connecting elements are inserted into the grooves 21 of the plates 2 and lie against the side walls directly, being held in these by positive engagement.
the connecting elements in the grooves of the support strips are secured by a potting compound.
all connecting elements are each arranged in the region of the butt joints between two plates 2 made of ceramic material, whereby by means of the connecting elements in each case two adjacent plates 2 are also rigidly fixed to each other, whereby they are held in the same altitude.
