Abstract

The invention relates to a fluidizing plate, comprising a supporting structure and plate segments, the plate segments respectively having openings through which gas flows during operation. The plate segments are respectively releasably connected to the supporting structure and two neighboring plate segments respectively overlap and are releasably connected to one another in the region of the overlap. The invention also relates to an apparatus with such a fluidizing plate.

First claim

1 . A fluidizing plate, comprising a supporting structure and plate segments, the plate segments respectively having openings through which gas flows during operation, wherein the plate segments are respectively releasably connected to the supporting structure and two neighboring plate segments respectively overlap and are releasably connected to one another in the region of the overlap.

2 . The fluidizing plate as claimed in claim 1 , wherein the releasable connection is a clamping connection.

3 . The fluidizing plate as claimed in claim 1 , wherein the plate segments are formed such that they are respectively connected to the supporting structure at the edge.

4 . The fluidizing plate as claimed in claim 3 , wherein a sealing element is placed in the region of the overlap between the overlapping plate segments.

5 . The fluidizing plate as claimed in claim 4 , wherein the sealing element is a sealing cord.

6 . The fluidizing plate as claimed in claim 4 , wherein the sealing element is made of polytetrafluoroethylene.

7 . The fluidizing plate as claimed in claim 1 , wherein the supporting structure is made up of struts that are inserted in one another.

8 . The fluidizing plate as claimed in claim 1 , wherein an opening into which an insert is placed is respectively formed at the screwing points, the insert being formed as a sleeve with a flanged edge, the flanged edge resting on the plate segment after the insert has been placed into the opening and a hole through which a screw is passed being formed in the insert.

9 . The fluidizing plate as claimed in claim 8 , wherein the outside diameter of the sleeve of the insert is 5 to 20% smaller than the diameter of the opening in the plate segment through which the insert is passed.

10 . The fluidizing plate as claimed in claim 1 , wherein the plate segments have a recess at the positions of the screw connections, so that after the screwing no screw head protrudes above the surface of the plate segments.

11 . An apparatus, comprising a fluidizing plate as claimed in claim 1 , a gas feed being arranged underneath the fluidizing plate and a gas outlet being arranged above the fluidizing plate and the apparatus also comprising a solid material feed and a solid material outlet.

12 . The apparatus as claimed in claim 11 , wherein a supporting construction on which the fluidizing plate rests is assembled in the apparatus.

13 . The apparatus as claimed in claim 12 , wherein the supporting structure of the fluidizing plate is releasably connected to the supporting construction.

14 . The apparatus as claimed in claim 12 , wherein leveling shims are inserted for leveling the plate between the supporting construction and the supporting structure.

15 . The apparatus as claimed in claim 12 , wherein the apparatus is a reactor for producing poly(meth)acrylate in the form of powder, the fluidizing plate being arranged at the lower end of the reactor, so that during operation the poly(meth)acrylate in the form of powder falls through the reactor onto the fluidizing plate, gas can be fed in from below through the gas feed and thus a fluidized bed is formed on the fluidizing plate.
