Description
TECHNICAL FIELD
[0001] The invention relates to a fluidization apparatus for processing particulate material, with a fluidization unit having a longitudinal axis, which fluidization unit has a perforated inflow distribution aperture plate, which divides the fluidization unit into a distribution chamber and a fluidization chamber arranged above the distribution chamber, wherein the fluidization chamber comprises a material inlet for the material to be processed and the distribution chamber comprises a material discharge having a material outlet for the processed material, which material outlet has a material outlet surface, a lower edge and an upper edge, and a closure device closes the material discharge, and wherein the distribution chamber comprises a fluid inlet and the fluidization chamber comprises a fluid outlet for a process gas, which fluidizes the material in the fluidization chamber, flowing from the fluid inlet through the perforated inflow distribution aperture plate to the fluid outlet. BACKGROUND
[0002] Fluidization apparatuses for processing particulate material and in particular fluidized bed apparatuses (Wirbelschichtapparate) have been known for a long time.
[0003] EP 261 1531 A1 discloses a fluidized bed apparatus for processing particulate material, which fluidized bed apparatus comprises a chamber enclosing a distribution chamber, a perforated inflow distribution aperture plate arranged above the distribution chamber, an inlet and an outlet for a process gas, and a discharge opening having a lower edge and an upper edge defining a height and an opening surface, wherein the inflow distribution aperture plate is positioned above the lower edge of the discharge opening such that the opening surface of the discharge opening is divided into an opening surface below the inflow distribution aperture plate and an opening surface above the inflow distribution aperture plate.
[0004] The disadvantage of this is that, in the case of a discharge of particulate material at the discharge opening while the process gas is flowing from the distribution chamber into the fluidization chamber around the inflow distribution aperture plate, the process gas forms a curtain (Vorhang). This curtain at least partially restricts the discharge of the particulate material and at the same time also reduces the emptying speed of the particulate material from the fluidization apparatus. SUMMARY
[0005] It is therefore the task of the invention to further improve the emptying of the fluidization apparatus in terms of the emptying speed, on the one hand, and to overcome the disadvantages of the prior art, on the other hand.
[0006] The task is solved in the fluidization device mentioned at the beginning by the following method: the distribution chamber includes a connecting piece that extends at least partially in the circumferential direction in the area of the material outlet surface, and the inlet distribution orifice plate is arranged to be movable relative to the fluidization unit, wherein the inlet distribution orifice plate can be brought into the emptied position by the movement of the inlet distribution orifice plate relative to the fluidization unit, wherein, in the emptied state, the inlet distribution orifice plate is arranged at the connecting piece in such a way that a fluid connection is formed between the material outlet arranged in the distribution chamber and the fluidization chamber passing by the inlet distribution orifice plate, so as to discharge the processed material from the fluidization unit, and wherein, in the emptied state, in the emptied position of the inlet distribution orifice plate, the locking device opens the material discharge section.
[0007] The advantage of this design is that the connecting piece (where the inlet distribution orifice plate is arranged) prevents the process gas flow from flowing around the inlet distribution orifice plate in the area of the material outlet surface, thereby forming a "process gas curtain" that restricts or completely blocks the discharge of the treated material. Furthermore, the connecting piece also prevents the material treated in the fluidization chamber from falling into the distribution chamber through the gap created between the inlet distribution orifice plate and the inner wall of the distribution chamber during discharge.
[0008] Advantageously, due to the relative motion between the inlet distribution orifice plate and the fluidization unit, the processed particulate material can be vented through the material discharge section. This relative motion can be carried out in such a way that the process gas supports the vented material through the material discharge section.
[0009] According to an advantageous design of the fluidization apparatus, the inlet distribution orifice plate is preferably arranged above the upper edge of the material outlet in the working position. When the inlet distribution orifice plate is in the working position, the fluidization apparatus is in operation. Therefore, in the working position, the material can be processed within the fluidization chamber without being discharged through the material outlet.
[0010] In the vented position, due to the movement of the inlet distribution orifice plate relative to the fluidization unit, the inlet distribution orifice plate is preferably positioned at least partially below the upper edge of the material outlet. In the vented position, the fluidization device is in a vented state.
[0011] According to a particularly advantageous improvement to the fluidization equipment, the upper side of the connecting plate is arranged tangentially to the material outlet surface of the material outlet, or arranged below the material outlet against the flow direction of the process gas. This arrangement of the connecting plate in the distribution chamber significantly improves the discharge of processed material from the fluidization unit, especially from the fluidization chamber itself. In this respect, the upper side of the connecting plate is advantageously arranged tangentially to the lower edge of the material outlet surface of the material outlet. This design is particularly advantageous because the processed material can therefore be discharged from the fluidization unit without obstruction.
[0012] Furthermore, the connecting piece is preferably constructed in a sickle shape, particularly a crescent shape, or an annular shape. This minimizes the impact on the flow of process gases, allowing the fluidization of the material to be treated within the fluidization chamber to continue to function well in the working position.
[0013] According to an advantageous design of the fluidization apparatus, the fluidization unit has a pivot axis extending transversely to the longitudinal axis of the fluidization unit, at which the inlet distribution orifice plate is pivotally arranged. Advantageously, the pivot axis extends perpendicularly to the central longitudinal axis of the fluidization unit. This embodiment allows for simple relative movement, in the form of pivoting about the pivot axis. Thus, on the one hand, the material outlet of the material discharge section arranged in the distribution chamber is opened to drain the material processed in the fluidization chamber, and on the other hand, the draining is facilitated by the inclined position of the inlet distribution orifice plate—as in the case of a liquid. Furthermore, the inlet distribution orifice plate preferably pivots about the pivot axis at an angle between 0° and 60°, advantageously between 5° and 10°. Through pivoting motion, a generally annular or sickle-shaped gap is formed between the inlet distribution orifice plate and the distribution chamber and / or fluidization chamber. This gap cannot be too large, otherwise there is a risk that, in the vented state, processed material may still enter the distribution chamber despite the process gas flowing through this gap. In principle, this gap is sealed by the process gas. In the area of the material outlet, the fluidization unit, particularly the distribution chamber, has no gap due to the connecting plate extending at least partially in the circumferential direction. The inlet distribution orifice plate pivots about the pivot axis and is arranged at the connecting plate.
[0014] In another advantageous alternative design to this fluidization apparatus, the inlet distribution orifice plate is arranged to be axially displaceable along the longitudinal axis. The inlet distribution orifice plate is displaced axially along the longitudinal axis in a linear motion. Advantageously, the inlet distribution orifice plate is displaced until its upper side is flush with or positioned below the lower edge. Preferably, the inlet distribution orifice plate is arranged to be axially displaceable along the longitudinal axis. With this alternative design, the material outlet is also opened to improve evacuation after processing particulate materials.
[0015] Furthermore, advantageously, the fluidization unit has a pivot axis extending transversely to the longitudinal axis of the fluidization unit and arranged to be axially displaceable along the longitudinal axis, at which the inlet distribution orifice plate can be pivotally arranged. This design of the fluidization device combines the advantages of two alternative designs of preferred fluidization devices (i.e., pivotal movement and linear movement). Moreover, where there are no connecting pieces, the gap formed between the fluidization unit and the inlet distribution orifice plate is smaller.
[0016] According to an additional advantageous configuration of the fluidization apparatus, the inlet distribution orifice plate, particularly its upper side, is at least partially positioned below the lower edge of the material outlet in the emptying position due to the movement of the inlet distribution orifice plate relative to the fluidization unit. Particularly preferred is that the inlet distribution orifice plate, particularly its upper side, is positioned below the lower edge of the material outlet in the emptying position due to the movement of the inlet distribution orifice plate relative to the fluidization unit. This maximizes the opening of the material outlet surface, allowing the processed material to be emptied effectively and rapidly.
[0017] Advantageously, a fluid interface for providing auxiliary gas is provided for the material discharge section, which is particularly configured as a vent pipe. This fluid interface includes a fluid connection outlet. Through the fluid interface, fluid, preferably auxiliary or supportive gas, can be supplied to the material discharge section to facilitate and improve the discharge of treated material. Preferably, this auxiliary gas corresponds to the process gas. More preferably, the auxiliary gas is separated from the process gas and is re-supplyed to the process gas in a cyclical manner after material discharge.
[0018] In this regard, according to the improved design of the fluidization equipment, the material discharge section has a shelf that divides the material discharge section into a material channel for transporting the processed material from the fluidization unit and a fluid channel for guiding auxiliary gas. A fluid connection outlet is arranged in the shelf, allowing the auxiliary gas to overflow from the fluid channel into the material channel. This provides a very simple and space-saving structure for introducing auxiliary gas, especially auxiliary air.
[0019] Preferably, the fluid connection outlet has a perforated cover, or is formed by holes in the shelf. The perforated cover or correspondingly designed holes prevent treated material discharged from the fluidization unit from falling into the fluid interface and clogging it. Particularly preferred is that the fluid connection outlet, especially a portion of the perforated cover or hole, is constructed such that the auxiliary gas has an outflow direction in the direction of discharge of the treated material. This highly preferred improvement further facilitates the discharge of the treated material.
[0020] Advantageously, the fluid connection outlet is located in the area of the material outlet surface. This ensures that the auxiliary gas directly promotes and / or supports the treated material to be discharged after the material outlet.
[0021] The following describes a method for processing particulate materials in a preferred fluidization apparatus. The method comprises a fluidization unit having a longitudinal axis, the fluidization unit having a perforated inlet distribution plate dividing the fluidization unit into a distribution chamber and a fluidization chamber disposed above the distribution chamber. The fluidization chamber includes a material inlet for the material to be processed, and the distribution chamber includes a material discharge section having a material outlet for processed material, the material outlet having a material outlet surface, a lower edge, and an upper edge. A locking device closes the material discharge section. The distribution chamber includes a fluid inlet, and the fluidization chamber includes a fluid outlet. A process gas for fluidizing the material in the fluidization chamber flows from the fluid inlet through the perforated inlet distribution plate to the fluid outlet. The fluidization chamber, in its operating state, is first filled with material to be processed through a material inlet, and then the material is processed by process gas flowing through the fluidization chamber. The distribution chamber includes a connecting plate that extends at least partially circumferentially in a region on the surface of the material outlet. After the operating state, an inlet distribution orifice plate movably arranged relative to the fluidization unit is moved to an empty position in such a way that, in the empty state, the inlet distribution orifice plate is positioned at the connecting plate such that a fluid connection is formed between the material outlet in the distribution chamber and the fluidization chamber, passing beside the inlet distribution orifice plate. The processed material is discharged from the fluidization unit through the material outlet. In the empty state, in the empty position of the inlet distribution orifice plate, a locking device opens the material discharge section.
[0022] The advantage of this design is that the connecting piece (where the inlet distribution orifice plate is arranged) prevents the process gas flow from flowing around the inlet distribution orifice plate in the area of the material outlet surface, thereby forming a "process gas curtain" that restricts or completely blocks the discharge of the treated material. Furthermore, the connecting piece also prevents the material treated in the fluidization chamber from falling into the distribution chamber through the gap created between the inlet distribution orifice plate and the inner wall of the distribution chamber during discharge.
[0023] Furthermore, advantageously, due to the relative motion between the inlet distribution orifice plate and the fluidization unit, the processed particulate material can be vented through the material discharge section. This relative motion can be carried out in such a manner that the process gas supports the vented material through the material discharge section.
[0024] According to an advantageous design related to the method, the fluidization unit has a pivot axis extending transversely to the longitudinal axis of the fluidization unit, at which the inlet distribution orifice plate is pivotally arranged, and after the granular material is processed, the inlet distribution orifice plate pivots about the pivot axis, advantageously pivoting 5° to 10°. This embodiment allows for simple relative movement in the form of pivoting about the pivot axis. Thus, preferably, on the one hand, the material outlet of the material discharge section arranged in the distribution chamber is opened to empty the material processed in the fluidization chamber, and on the other hand, the tilted position of the inlet distribution orifice plate facilitates this emptying. Furthermore, the inlet distribution orifice plate preferably pivots about the pivot axis at an angle between 0° and 60°, advantageously 5° to 10°. Through pivoting motion, a generally sickle-shaped or annular gap is formed between the inlet distribution orifice plate and the distribution chamber and / or fluidization chamber. This gap cannot become too large, otherwise there is a risk that, in the vented state, although process gas flows through this gap, processed material may still enter the distribution chamber. The process gas advantageously seals the gap in the vented state (where no connecting tabs are arranged).
[0025] According to an equally advantageous design related to this method, the inlet distribution orifice plate is arranged to be axially displaceable along the longitudinal axis, and in a linear motion, advantageously until the inlet distribution orifice plate is positioned below the lower edge of the material outlet. Preferably, the inlet distribution orifice plate is axially displaced along the longitudinal axis. With this alternative design, the material outlet is also opened to improve evacuation after processing granular materials.
[0026] Particularly preferred is that, upon being brought into the venting position, the inflow distribution orifice plate performs both pivoting and linear motion. In this case, the inflow distribution orifice plate pivots about a pivot axis via a pivoting motion, and simultaneously shifts axially along the longitudinal axis via a linear motion. The pivoting and linear motions can be performed sequentially or simultaneously in any order. This allows the advantages of both pivoting and linear motions to be utilized.
[0027] According to an additional advantageous design of the method, the inlet distribution orifice plate is moved to the evacuation position relative to the fluidization unit such that at least a portion of the inlet distribution orifice plate is positioned below the lower edge of the material outlet. Furthermore, the inlet distribution orifice plate is moved to the evacuation position relative to the fluidization unit such that the inlet distribution orifice plate is positioned below the lower edge of the material outlet. Alternatively, the upper edge or upper side of the inlet distribution orifice plate is arranged flush with the lower edge of the material outlet. In both cases, the material outlet surface is opened to the maximum extent, thereby allowing for efficient and rapid evacuation of the processed material.
[0028] According to an additional advantageous improvement of the method, the material discharge section has a locking device that opens the material discharge section once the inlet distribution orifice plate is in the emptied position. Preferably, the locking device opens the material discharge section once at least a portion of the inlet distribution orifice plate is positioned below the lower edge of the material outlet. Thus, the material outlet surface is opened to the maximum extent, and the material processed in the fluidization chamber of the fluidization unit can be efficiently and time-savingly discharged from the fluidization unit of the fluidization equipment.
[0029] According to another advantageous improvement of the method, a fluid interface for providing auxiliary gas is provided for the material discharge section, which is particularly configured as a vent pipe. This fluid interface includes a fluid connection outlet, through which the auxiliary gas flows into the material discharge section at least when the locking device opens, to facilitate the discharge of treated material. Through the fluid interface, fluid, preferably auxiliary or supporting gas, can be supplied to the material discharge section to promote and improve the discharge of treated material. Preferably, the auxiliary gas corresponds to the process gas. More preferably, the auxiliary gas is separated from the process gas and is re-supplyed to the process gas in a cyclic manner after material discharge.
[0030] Particularly preferred is that the fluid connection outlet, particularly the perforated cap or part of the hole, is configured such that the auxiliary gas has an outflow direction in the direction of discharge of the treated material. This highly preferred improvement further facilitates the discharge of the treated material.
[0031] Advantageously, the methods described above are performed on fluidized devices. Attached Figure Description

Detailed Implementation
[0052] Unless otherwise stated, the following description pertains to all embodiments of the fluidization apparatus 1 shown in the figures for processing particulate material M.
[0053] Figure 1 A top view of a first embodiment of a fluidization device 1 with a cutting plane AA is shown, the fluidization device being configured as a fluidized bed device 2. The fluidization device 1 includes a fluidization unit 3 having a central longitudinal axis XX, at which a drain pipe 4 is arranged, the drain pipe including a central axis YY perpendicular to the longitudinal axis XX. The central axis YY and the longitudinal axis XX extend the cutting plane AA. The fluidization device 1 is in an operational state.
[0054] exist Figure 2 The text shows along Figure 1 The cross-section of the cutting plane AA shown is a schematic diagram of a first embodiment of the fluidization device 1 in the working position, which is configured as a fluidized layer device 2.
[0055] The fluidization unit 3 includes a perforated inlet distribution plate 7, which divides the fluidization unit 3 into a distribution chamber 5 and a fluidization chamber 6 arranged above the distribution chamber 5. In the working position, the inlet distribution plate 7 is located in the ZZ plane, which is perpendicular to the cutting plane AA, so that the material M to be processed is arranged in the fluidization chamber 6 above the inlet distribution plate 7. If the inlet distribution plate 7 is in the working position, the fluidization device 1 is in the working state.
[0056] The fluidization unit 3 of the fluidization device 1, which is configured as the fluidization layer device 2, is designed to be rotationally symmetrical about the central longitudinal axis XX. Other geometries, such as rectangles, and especially squares, are implemented in other embodiments not shown.
[0057] exist Figure 2 In the embodiment shown, the dispensing chamber 5 has a cylindrical shape with a constant inner diameter 9 at a height 8. The dispensing chamber 5 has a dispensing chamber wall 10 radially spaced from the longitudinal axis XX. The dispensing chamber wall 10 has an inner surface referred to as the inner wall 11 and an outer surface referred to as the outer wall 12.
[0058] In the illustrated embodiment, the fluidization chamber 6 is also constructed as a cylinder, wherein, compared to the distribution chamber 5, the fluidization chamber 6 has a conical shape, the conical shape having an inner diameter 14 of the fluidization chamber that increases from bottom to top along the fluidization chamber height 13. The fluidization chamber 6 has fluidization chamber walls 15 radially spaced from the longitudinal axis XX. The fluidization chamber walls 15 have an inner surface referred to as the inner fluidization chamber wall 16 and an outer surface referred to as the outer fluidization chamber wall 17.
[0059] The fluidization chamber 6 also includes a material inlet 18 for the material M to be processed, and the distribution chamber 5 includes a material discharge section 19 for the processed material M′. The material discharge section 19 is specifically designed as a discharge pipe 4 with a discharge pipe wall 20, in... Figure 2 In the embodiment shown, the drain pipe is arranged in the distribution chamber wall 10 with rotational symmetry about the central axis YY, perpendicular to the longitudinal axis XX of the fluidization unit 3. Here, the material outlet 21 of the material discharge section 19 is arranged such that it is flush with the inner wall 11 of the distribution chamber. The material outlet 21 has a material outlet surface 22 and lower and upper edges 23a, 23b for discharging the material M′ processed in the fluidization chamber 6.
[0060] The material outlet 21 of the material discharge section 19 has a locking device 24. The locking device 24 is closed in the working position of the inlet distribution orifice plate 7. The locking device 24 is advantageously designed as a flap 26 that can pivot about the pivot axis 25. Therefore, in the working state, the material discharge section 19 of the fluidization unit 3 of the fluidization device 1 is closed. In addition, the locking device 24 can also be arranged in other positions along the central axis YY in the material discharge section 19, which is configured as a drain pipe 4.
[0061] Furthermore, the distribution chamber 5 has a fluid inlet 27, and the fluidization chamber 6 has a fluid outlet 28. Figure 2 In the operating position shown, a perforated inlet distribution plate 7 is arranged horizontally in plane ZZ. Process gas PG enters the fluidization unit 3 at fluid inlet 27 and flows from fluid inlet 27 through the perforated inlet distribution plate 7 to fluid outlet 28, where it exits the fluidization unit 3. The perforated inlet distribution plate 7 advantageously has through-holes (not shown) for the process gas PG, through which pressure loss occurs during flow. In the operating state, i.e., in the operating position of the inlet distribution plate 7, the process gas PG fluidizes the material M to be treated in the fluidization chamber 6.
[0062] The inlet distribution orifice plate 7 is movably arranged within the fluidization unit 3 relative to the fluidization unit 3. In the fluidization device 1... Figure 2 In the illustrated embodiment, the fluidization unit 3 has a pivot axis 29 extending transversely to the longitudinal axis XX of the fluidization unit 3, and the inlet distribution orifice plate 7 is pivotally arranged at this pivot axis. In the first embodiment of the fluidization device 1 shown, the pivot axis 29 advantageously extends perpendicularly to the longitudinal axis XX of the fluidization unit 3 and perpendicularly to the central axis YY of the drain pipe 4. In the fluidization device 1... Figure 3In the operating state shown, the inlet distribution orifice plate 7 is arranged above the upper edge 23b. This ensures that during the treatment of particulate material M with process gas PG in the fluidization chamber 6, no material M is discharged from the fluidization unit 3 of the fluidization device 1.
[0063] Furthermore, the dispensing chamber 5 has a connecting piece 30 arranged in the area of the material outlet surface 22, extending at least partially in a circumferential direction. The upper side 31 of the connecting piece 30 is arranged tangentially to the material outlet surface 22 of the material outlet 21. Advantageously, the upper side 31 of the connecting piece 30 is arranged tangentially to the lower edge 23a of the material outlet surface 22 of the material outlet 21. In this case, the connecting piece 30 is constructed in a sickle shape, especially a crescent shape.
[0064] Figure 4 The diagram shows a fluidization apparatus 1 configured as a fluidizing layer device 2 in an empty state. After particulate material M is processed in the fluidizing layer device 2, the processed material M′ is discharged from the fluidization apparatus 1 through material channel 42 in an empty state. For this purpose, an inlet distribution orifice plate 7, which can be brought into the empty position, moves relative to the fluidization unit 3 in a pivotal motion, thereby pivotally positioning the inlet distribution orifice plate in the fluidization unit 3 about a pivot axis 29 in the empty position. If the inlet distribution orifice plate 7 is in the empty position, the fluidization apparatus 1 is in an empty state.
[0065] In the vented position, the inlet distribution orifice plate 7 is pivoted at an angle α around the pivot axis 29, such that the inlet distribution orifice plate 7 is positioned at the connecting piece 30. This creates a fluid connection between the material outlet 21 in the distribution chamber 5 and the fluidization chamber 6, passing alongside the inlet distribution orifice plate 7, to discharge the processed material from the fluidization unit 3. Advantageously, the inlet distribution orifice plate 7 is pivoted by an angle of 5° to 10°. This causes the processed material M′ to flow towards the material outlet 21. The discharge of the processed material M′ is supported by process gas PG, which, in the vented state, also flows from the fluid inlet 27 through the fluidization unit 3 of the fluidization device 1 to the fluid outlet 28.
[0066] Once the inlet distribution orifice plate 7 is positioned at the connecting piece 30 in the emptied state, the locking device 24 opens the material discharge section 19. Then, the material M′ processed in the fluidization unit 3 is discharged. Preferably, in the emptied state, the locking device 24 is opened to the maximum extent possible, thereby maximizing the material outlet surface 22 of the material outlet 21, which further promotes improved discharge of the processed material M′.
[0067] In the vented position, due to the pivoting motion caused by the inlet distribution orifice plate 7 pivoting around the pivot axis 29, a gap 32 is formed between the inlet distribution orifice plate 7 and the fluidization unit 3, particularly between the inlet distribution orifice plate 7 and the inner wall 11 and / or the inner wall 16 of the distribution chamber. This gap extends substantially around the entire circumference of the inlet distribution orifice plate 7. The width of the gap formed in this case is variable. In the vented state, the process gas PG flows through the gap 32, so that the processed material M′ cannot enter or fall into the distribution chamber 5 when it is discharged from the fluidization chamber 6.
[0068] In the area of material outlet 21, the connecting piece 30 prevents the material M′ to be discharged from entering or falling in, and on the other hand, the connecting piece 30 (where the inlet distribution orifice plate 7 is arranged) prevents the process gas flow from flowing around the inlet distribution orifice plate 7 in the area of material outlet surface 22 and thereby forming a "process gas curtain" that restricts or completely prevents the discharge of the processed material.
[0069] exist Figure 1 The text shows the data based on... Figure 5 This is a top view of a schematic diagram of a first embodiment of the fluidization device 1, wherein the fluidization device 1 is in a vented state. In this case, the inlet distribution orifice plate 7 is arranged at the connecting piece 30 at a position pivoted by an angle α about the pivot axis 29, thereby forming a gap 32 with varying gap width between the inlet distribution orifice plate 7 and the fluidization unit 3, particularly the inner wall 11 of the distribution chamber and / or the inner wall 16 of the fluidization chamber. During the venting process, the process gas PG flows through the gap 32, thereby allowing untreated material M to enter the distribution chamber 5.
[0070] In the region of the material outlet surface 22, a connecting piece 30 arranged in the distribution chamber 5 extends circumferentially. The upper side 31 of the connecting piece 30 is arranged tangentially to the lower edge 23a of the material outlet surface 22 of the material outlet 21. In this case, the connecting piece 30 is constructed in a sickle shape, especially a crescent shape. The connecting piece 30 has an angle β of 160°. In other embodiments not shown here, the connecting piece 30 preferably has an angle β of 5° to 180°, more preferably an angle of 10° to 60°.
[0071] Figure 4 A schematic projection of the inner wall 11 of the dispensing chamber of a first embodiment of the fluidization device 1 in the emptied position is shown. This inner wall includes a connecting piece 30 and a material outlet 21. (As already shown...) Figure 5 As described, the upper side 31 of the connecting piece 30 is arranged tangentially to the lower edge 23a of the material outlet surface 22 of the material outlet 21. The material outlet surface 22 is thus opened to the maximum extent. Figure 6The locking device 24 (not shown) opens the material discharge section 19 in the emptied position, thereby allowing the processed material M′ to be effectively discharged from the fluidization chamber 6 through the material outlet surface 22, which is opened to the maximum extent in the fluidization unit 3. The projection view includes a sickle-shaped connecting piece 30, wherein the connecting piece 30 has an angle β of approximately 160°.
[0072] Figure 1 Corresponding to Figure 7 The diagram shows a top view of a second embodiment of a fluidization device 1 with a cutting plane AA, wherein the fluidization device is configured as a fluidized bed device 2. The fluidization device 1 includes a fluidization unit 3 having a central longitudinal axis XX, at which a drain pipe 4 including a central axis YY perpendicular to the longitudinal axis XX is arranged. The central axis YY and the longitudinal axis XX extend the cutting plane AA. The fluidization device 1 is in an operational state.
[0073] exist Figure 6 The middle shows along Figure 8 The cross-section of the cutting plane AA is shown in the schematic diagram of the second embodiment of the fluidization device 1 in its working state. In the working position, the inlet distribution orifice plate 7 is located in the plane ZZ that is perpendicular to the cutting plane AA, so that the material M to be processed is arranged above the inlet distribution orifice plate 7 in the fluidization chamber 6 in the working state, and can be fluidized and processed there.
[0074] Furthermore, the second embodiment of the fluidization device 1 is structurally constructed in a manner substantially identical to the first embodiment of the fluidization device 1. The two embodiments differ in the technical design of the relative movement performed between the fluidization unit 3 and the inlet distribution orifice plate 7. In the second embodiment, the inlet distribution orifice plate 7 does not perform a pivoting movement as in the first embodiment, but rather performs a linear movement along the axial direction 33 of the longitudinal axis XX. Therefore, the inlet distribution orifice plate 7 is arranged to be movable along the axial direction 33 of the longitudinal axis XX.
[0075] Furthermore, the connecting piece 30 is arranged below the material outlet 21 against the flow direction of the process gas, which further distinguishes the second embodiment from the first embodiment. Therefore, the connecting piece 30 is arranged at a distance c from the lower edge 23a of the material outlet surface 22. In particular, in the embodiment not shown, the distance c is infinitesimally small, advantageously equal to zero.
[0076] exist Figure 6 The middle shows along Figure 9A cross-section of the cutting plane AA, which is a schematic diagram of a second embodiment of the fluidization device 1 at the discharge position, the fluidization device having an inlet distribution orifice plate 7 arranged in a horizontal position in a plane Z′-Z′. The plane Z′-Z′ extends parallel to the plane ZZ by a distance d. The inlet distribution orifice plate 7 moves downward a distance d along the axial direction 33 of the central longitudinal axis XX, i.e., from the plane ZZ to the plane Z′-Z′. In the illustrated embodiment, the inlet distribution orifice plate 7 is located on the connecting piece 30, so that advantageously the upper edge 34 and / or upper side 35 of the inlet distribution orifice plate 7 is arranged at the same height as the lower edge 23a of the material outlet 21. The upper edge 34 and / or upper side 35 of the inlet distribution orifice plate 7 is arranged tangentially to the lower edge 23a of the material outlet 21. Therefore, the material outlet surface 22 of the material outlet 21 is fully opened, thereby allowing for improved discharge of the processed material M′ through the material channel 42.
[0077] Advantageously, at least one outlet 36, and in particular multiple outlets 36, are arranged in the area of material outlet 21 within the perforated inlet distribution plate 7, and these outlets are aligned toward material outlet 21 according to the arrow 37 shown. This additionally supports the discharge of the treated material M′ by process gas PG in the vented state.
[0078] Figure 8 It shows in Figure 10 The enlarged view of section A shown represents the area of material outlet 21. The perforated inlet distribution plate 7 has through-holes 38 through which process gas PG flows to fluidize the particulate material M to be treated in the fluidization chamber 6. The through-holes 38 can be arranged arbitrarily, wherein the number and diameter of the through-holes 38 are designed according to the specific requirements for the fluidization and / or treatment of the material M.
[0079] Within the area of material outlet 21, outlet 36 is arranged in a perforated inlet distribution orifice plate 7. Process gas PG flows through outlet 36 in the direction of arrow 37, thus supporting efficient and rapid discharge of processed material M′ in the venting position. For example, outlet 36 may be arranged within an arcuate segment preceding material outlet 21. Furthermore, the upper edge 34 and / or upper side 35 of inlet distribution orifice plate 7 is lowered until it is flush with the height of the lower edge 23a of material outlet 21, thereby additionally promoting and facilitating the discharge of processed material M′ due to the maximum possible material outlet surface 22.
[0080] Figure 11A top view of a third embodiment of a fluidization device 1 with a cutting plane AA is shown, the fluidization device being designed as a fluidized bed device 2. The fluidization device 1 includes a fluidization unit 3 having a central longitudinal axis XX, at which a drain pipe 4 is arranged. The drain pipe includes a central axis YY perpendicular to the longitudinal axis XX, wherein the central axis YY and the longitudinal axis XX extend through the cutting plane AA. The fluidization device 1 is in an operational state.
[0081] exist Figure 9 The middle shows along Figure 11 The cross-section of the cutting plane AA, the cutting plane being through a schematic diagram of the third embodiment of the fluidization device 1 in operation, the fluidization device in operation having an inlet distribution orifice plate 7 arranged in a horizontal position within the plane WW.
[0082] The third embodiment of the fluidization device 1 is essentially a combination of the first two embodiments. In the third embodiment, the inlet distribution orifice plate 7 can also be moved relative to the fluidization unit 3. Unlike the first and second embodiments, the inlet distribution orifice plate 7 in the third embodiment is adapted to perform pivoting motion about the pivot axis 29 on the one hand, and linear motion along the axial direction 33 of the longitudinal axis XX on the other hand. In the operating state shown, the particulate material M is processed in the fluidization chamber 6.
[0083] As the inflow distribution orifice plate 7 is moved from the working position to the venting position, the pivoting and linear movements of the inflow distribution orifice plate can be performed sequentially or simultaneously in any order. This allows the advantages of both pivoting and linear movements to be utilized. In this embodiment, the pivoting and linear movements are performed simultaneously.
[0084] The material discharge section 19 has a locking device 24 that can pivot about a pivot axis 25. The locking device 24 is advantageously configured as a flap 26, a valve, or a sluice gate or the like. In the third embodiment, the locking device 24, configured as a flap 26, closes or opens the material discharge section 19. Figure 12 In the operating state shown—with the inlet distribution orifice plate 7 positioned above the lower edge 23a and below the upper edge 23b of the material outlet 21—the locking device 24 closes the material discharge section 19. Therefore, neither the process gas PG nor the material M to be processed can flow out or be discharged from the fluidization unit 3 of the fluidization device 1, particularly from the fluidization chamber 6. In the illustrated embodiment, the valve 26 is arranged to pivot about a pivot axis 25 orthogonal to the central axis YY.
[0085] Figure 10 It shows along Figures 13 to 17A cross-section of the cutting plane AA, the cutting plane passing through a schematic diagram of the third embodiment of the fluidization device 1.
[0086] In the emptied state, the particulate material M′ processed in the fluidization chamber 6 is discharged from the fluidization unit 3 of the fluidization device 1 through the material discharge section 19, which is configured as an empty pipe 4 and includes a material channel 42. In this case, the locking device 24 pivots about the pivot axis 25 and, in the emptied state—with the inlet distribution orifice plate at least partially below the upper edge 23b of the material outlet 21—opens the material discharge section 19.
[0087] In this configuration, the inlet distribution orifice plate 7 pivots at an angle α about the pivot axis 29, and simultaneously, the pivot axis 29 is moved axially 33 along the longitudinal axis XX from plane WW to plane W′-W′, which is parallel to and aligned with plane WW. By lowering the pivot axis 29 of the inlet distribution orifice plate 7 from plane WW to plane W′-W′, which has been moved a distance d parallel to it, and by simultaneously pivoting the inlet distribution orifice plate 7 about the pivot axis 29, an improved discharge of the treated material M′ from the fluidization chamber 6 is achieved. In the illustrated embodiment, plane W′-W′ is positioned above the central axis YY. This allows the angle α of the pivot of the inlet distribution orifice plate 7 about the pivot axis 29 to be kept small, thereby minimizing the gap 32 formed between the inlet distribution orifice plate 7 and the fluidization unit 3, particularly the inner wall 11 of the distribution chamber and / or the inner wall 16 of the fluidization chamber. This results in a further improved discharge of the treated material M′.
[0088] The upper side 35 of the inlet distribution orifice plate 7 is positioned above the lower edge 23a of the material outlet 21 in the vented position. The material discharge section 19, which has a locking device 24, is opened by the locking device 24, which pivots about the pivot axis 25, so that the processed material M′ can be discharged with the support of the process gas PG flowing through the discharge outlet 36.
[0089] exist Figures 1 to 5 The fourth embodiment of the fluidization device 1 shown is structurally similar to that in... Figure 13 The first embodiment of the fluidization device 1 shown is basically the same. The difference between the two embodiments lies in the design of the material discharge section 19, which is configured as the drain pipe 4, and the arrangement of the associated connecting piece 30.
[0090] Figure 14This diagram shows a top view of a fourth embodiment of a fluidization device 1 configured as a fluidizing layer device 2, having a cutting plane AA. The fluidization device 1 includes a fluidization unit 3 having a central longitudinal axis XX, at which a drain pipe 4 is arranged, including a central axis YY perpendicular to the longitudinal axis XX, wherein the central axis YY and the longitudinal axis XX extend through the cutting plane AA. The fluidization device 1 is in an operational state.
[0091] exist Figure 14 The diagram shows the fluidization apparatus 1 in operation. In this case, an inlet distribution orifice plate 7, located in plane WW, separating the distribution chamber 5 and the fluidization chamber 6, is arranged above the upper edge 23b of the material outlet 21. The material M to be processed is treated, in particular, by process gas PG, in the fluidization chamber 6 of the fluidization unit 3 of the fluidization apparatus 1. The process gas PG flows from the fluid inlet 27 through the perforated inlet distribution orifice plate 7 toward the fluid outlet 28 through the fluidization unit 3.
[0092] Compared with the first embodiment, in Figure 15 In the fourth embodiment, a fluid interface 40 for providing auxiliary gas HG is provided to the material discharge section 19 configured as a vent pipe 4. The fluid interface includes a fluid connection outlet 39. The fluid connection outlet 39 is arranged in the region of the material outlet surface 22 of the material outlet 21.
[0093] The material discharge section 19, configured as an exhaust pipe 4, has a shelf 41. The shelf 41 divides the material discharge section 19 into a material channel 42 for transporting processed material M′ from the fluidization unit 3 and a fluid channel 43 for guiding auxiliary gas HG. A fluid connection outlet 39 is advantageously arranged in the shelf 41, allowing the auxiliary gas HG to overflow from the fluid channel 43 into the material channel 42. The fluid connection outlet 39 is formed by a hole 44 in the shelf 41. Here, the fluid connection outlet 39, and in particular the hole 44, is advantageously formed such that the auxiliary gas HG has an outflow direction in the direction in which the processed material M′ is discharged from the fluidization device 1.
[0094] Figure 16 The fluidization device 1 in a vented state is shown. In the vented state, the inlet distribution orifice plate 7 is arranged in the vented position, i.e., the inlet distribution orifice plate 7 has been moved relative to the fluidization unit 3 such that it is positioned at the connecting piece 30. In the vented state, the inlet distribution orifice plate 7 is located on the connecting piece 30. The venting of the processed material M′ is carried out through the material channel 42, wherein the auxiliary gas HG flows into the material channel 42 from the fluid channel 43 through the fluid connection outlet 39, and here facilitates the venting of the processed material M′ from the fluidization device 1.
[0095] existFigure 13 The text shows the data based on... Figure 17 This is a top view of a schematic diagram of a fourth embodiment of the fluidization device 1, wherein the fluidization device 1 is in a vented state. In this case, the inlet distribution orifice plate 7 is arranged at the connecting piece 30 at a position pivoted by an angle α around the pivot axis 29, thereby forming a gap 32 with varying gap width between the inlet distribution orifice plate 7 and the fluidization unit 3, particularly the inner wall 11 of the distribution chamber and / or the inner wall 16 of the fluidization chamber. During the venting process, the process gas PG flows through the gap 32, allowing untreated material M′ to enter the distribution chamber 5.
[0096] In the area of the material outlet surface 22, a connecting piece 30, arranged on the inner wall 11 of the distribution chamber, extends circumferentially. The upper side 31 of the connecting piece 30 is arranged at the upper edge 45 of the shelf 41. The upper side 31 of the connecting piece 30 and the upper side 46 of the shelf 41 thus form flat upper sides 31, 46 that are flush with each other. The connecting piece 30 is constructed in this case in a sickle shape, particularly a crescent shape. The connecting piece 30 has an angle β of 160°.
[0097] Figure 16 A schematic projection of the inner wall 11 of the dispensing chamber of a fourth embodiment of the fluidization device 1 in an emptied position is shown. This inner wall includes a connecting piece 30 and a material outlet 21. (As already shown...) Figure 17 As described, the upper side 31 of the connecting piece 30 is arranged tangentially to the upper edge 45 of the shelf 41 of the material discharge section 19. The upper side 31 of the connecting piece 30 and the upper side 46 of the shelf 41 thus form flat upper sides 31, 46 that are flush with each other. The material outlet surface 22 is therefore smaller than that of the first embodiment. The material outlet surface 22 is thus divided into a material outlet surface 22a allocated to the material channel 42 and a material outlet surface 22b allocated to the fluid channel 43. Here, the material outlet surface 22a is opened by the locking device 24 in the emptied state, and the material outlet surface 22b is configured as the inner wall 11 of the distribution chamber.
[0098] Figure 18 The locking device 24 (not shown) opens the material discharge section 19, particularly the material outlet surface 22a, in the emptied state, thereby allowing the processed material M to be effectively discharged from the fluidization chamber 6 of the fluidization unit 3 through the material channel 42 and supported by the auxiliary gas HG flowing out from the fluid channel 43. The projection view includes a connecting piece 30 constructed in a sickle shape. The connecting piece 30 has an angle β of approximately 160°.
[0099] Figure 19 and Figure 18 A further fifth embodiment of the fluidization device 1 is shown. In this case,Figure 19 A top view showing a schematic diagram of a fifth embodiment of a fluidization device 1 with a cutting plane AA in its working position is shown, and Figure 18 It shows along Figure 19 The cross-section of the cutting plane AA shown is through a schematic diagram of the fifth embodiment of the fluidization device 1 in the emptied position, the fluidization device in the emptied position having an inlet distribution orifice plate 7 arranged on the pivot axis 29, the inlet distribution orifice plate being in a position pivoted about the pivot axis 29 by an angle α.
[0100] The fifth embodiment is structurally similar to the first embodiment. The difference between the two embodiments is that the connecting piece 30 is arranged below the material outlet 21 against the flow direction of the process gas PG. The connecting piece 30 is spaced apart from the lower edge 23a of the material outlet surface 22.
[0101] Furthermore, the two embodiments differ in that a fluid interface 40 for providing auxiliary gas HG is provided for the material discharge section 19, which is configured as the vent pipe 4. This fluid interface has a fluid connection outlet 39. The fluid connection outlet 39 is arranged in the vent pipe wall 22 and is provided with a perforated cover 47. The holes 48 penetrating the perforated cover 47 are aligned such that the auxiliary gas HG exiting from the fluid interface 40 and entering the material channel 42 flows in the direction that the processed material M′ is discharged from the fluidization device 1.
[0102] A locking device 24, configured as a valve 26, is arranged to pivot about a pivot axis 25, wherein the pivot axis 25 is arranged perpendicular to and intersects the central axis YY. In the venting position shown, valve 26 opens material discharge section 19 to vent fluidization chamber 6.
