Description

Technical Field

[0001] The utility model relates to the technical field of fluidized beds, in particular to a material turning device for a fluidized bed. Background Art

[0002] Fluidized bed, referred to as fluidized bed, is a reactor that uses gas or liquid to pass through a granular solid layer to put solid particles in a suspended motion state and carry out a gas-solid phase reaction process or a liquid-solid phase reaction process. It includes dispersed fluidized bed and aggregated fluidized bed (bubbling bed, turbulent bed, fast bed).

[0003] After the fluidized bed has reacted the material, the moisture content of the material is between 31% and 36% during the reaction, so the material needs to be transported to the drying area for drying. However, the material will agglomerate during transportation in the drying area. Therefore, the agglomerated material is turned over by a turning device. The turning device in the fluidized bed drying area is usually composed of a drive device, a chain and multiple trawl nets.

[0004] However, in order to ensure ventilation in the drying area, a ventilation floor is usually laid at the bottom of the drying area. During the drying process, affected by the high temperature in the drying area, the ventilation floor will expand and contract, causing the ventilation floor to tilt and catch the trawl net. In addition, because the material cannot pass through the hot air, it is blown away obliquely in the drying area. Over time, the trawl net cannot drag away more agglomerated materials, and the materials will accumulate more and more, which will get stuck in the trawl net, causing the trawl net to deform and the chain to get stuck, resulting in serious equipment failure.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0031] See attached Figure 1As shown, the utility model provides a technical solution: a material turning device for a fluidized bed, comprising two chains 10 and a plurality of material turning mechanisms 20, the plurality of material turning mechanisms 20 being arranged at intervals along the running path of the chains 10, the material turning mechanisms 20 comprising a cross beam 21 and a plurality of material turning assemblies 22, the cross beam 21 being connected to the two chains 10, the plurality of material turning assemblies 22 being arranged at intervals along the length direction of the cross beam 21.

[0032] For example, the turning assembly 22 may be a plate-like structure or a columnar structure.

[0033] According to this embodiment, when the fluidized bed dries the material, the chain 10 is driven by the driving device, and the chain 10 drives the plurality of material turning mechanisms 20 to move along the running path of the chain 10. At this time, in the drying area, the material turning assembly 22 fully turns the agglomerated material, which can reduce the probability of material agglomeration and bed pressing. This can reduce the risk of safety accidents and improve the yield rate.

[0034] See attached Figures 1-2 As shown, in some embodiments, the material turning assembly 22 includes a lifting plate 221 and a connecting member 222 , and the lifting plate 221 is disposed at one end of the connecting member 222 away from the crossbeam 21 .

[0035] According to this embodiment, the agglomerated materials can be turned over by the cooperation of the lifting plate 221 and the connecting member 222. At the same time, the plate-shaped lifting plate 221 can break up the relatively loose agglomerated materials, thereby reducing the accumulation of agglomerated materials and facilitating the turning of the materials.

[0036] In some embodiments, the connector 222 is a damper.

[0037] Exemplarily, the damper may be a gas damper or a liquid damper, etc.

[0038] According to this embodiment, during the process of the copying plate 221 turning over the material, when the copying plate 221 is subjected to an excessively large force, the connecting member 222 can offset it to prevent the copying plate 221 from being damaged.

[0039] See attached Figures 2-3 As shown, in other embodiments, the connecting member 222 includes a first cylinder 2221, a second cylinder 2222 and an elastic portion 2223, the second cylinder 2222 is disposed at an end of the first cylinder 2221 away from the beam 21, the second cylinder 2222 moves relative to the first cylinder 2221, and the elastic portion 2223 is disposed between the first cylinder 2221 and the second cylinder 2222.

[0040] Exemplarily, the elastic part 2223 is a spring or a rubber elastic pad, etc. The first cylinder 2221 can be detachably connected to the crossbeam 21 by at least two nut threads.

[0041] According to this embodiment, when the lifting board 221 is subjected to excessive force during the material turning process, the second cylinder 2222 moves toward the first cylinder 2221, and the elastic part 2223 offsets the force, thereby protecting the lifting board 221. In addition, such a design is not only simple in structure, but also convenient in manufacture, which can reduce the manufacturing cost.

[0042] See attached Figure 3 As shown, in some embodiments, a guide rod 22211 extending toward the first cylinder 2221 and inserted into the first cylinder 2221 is provided in the second cylinder 2222 , and the elastic portion 2223 is sleeved on the guide rod 22211 .

[0043] According to this embodiment, the guide rod 22211 can not only ensure the linear movement of the second cylinder 2222 , but also prevent the elastic portion 2223 from being skewed, thereby ensuring the smooth movement of the connecting member 222 .

[0044] See attached Figure 1 and 4 As shown, in some embodiments, multiple pairs of brackets 30 are included, and the multiple pairs of brackets 30 are arranged at intervals along the length direction of the beam 21, and the multiple pairs of brackets 30 correspond one by one to the multiple material turning mechanisms 20.

[0045] According to this embodiment, the crossbeam 21 can be easily assembled and disassembled, thereby improving work efficiency.

[0046] Optionally, the copy plate 221 and the connecting piece 222 are both made of metal, such as stainless steel and iron-chromium-aluminum alloy.

[0047] According to this embodiment, based on the high temperature of the discharge channel, the characteristics of the material can provide strength for the continuous copying plate 221 and the connecting member 222, thereby reducing the probability of deformation of the copying plate 221 and the connecting member 222.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
