The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The first embodiment is as follows:
as shown in fig. 1 and 2, a rotary adjustment type gas uniform distribution device comprises a plurality of flow guide structures 1 arranged in parallel along a first linear direction a, and a space between every two adjacent flow guide structures 1 is used for air flow to pass through; the flow guide structure 1 is arranged around a set axis 2 in a rotating mode, and the set axis 2 is perpendicular to the first straight line direction A; the device also comprises an adjusting device 3 which outputs power for rotating the diversion structures 1, transmits the power to each diversion structure 1 and keeps the current angle of the diversion structure 1 after the power output is finished.
In the embodiment, an air uniform distribution device capable of adjusting the direction of actually flowing air flow for different air distributors is provided, so that the deviation between the direction of the air flow from the air distributors and the direction of the precursor flow B is compensated, namely, the air flow matched with the air distributors is realized through different rotation angles, and the air flow with the same direction of the precursor flow B is finally output; the gas distributor adopting the gas uniform distribution device can effectively solve the problems of turbulence and non-uniformity of gas flow when the gas flow enters the main chamber, thereby effectively ensuring the effect of protofilament oxidation.
In the specific implementation process, the adjusting device 3 is used as a control end to perform the angle adjustment, and when the single angle adjustment is completed to the next angle adjustment, the set angle of the diversion structure 1 is maintained by controlling the adjusting device 3, so that the stable working state is maintained.
As an optimization, the adjusting device 3 transmits power to each flow guiding structure 1 synchronously; after power is output, the synchronous rotation of the diversion structures 1 is kept, so that the integral adjustment of airflow distribution in the oxidation chamber can be effectively realized, and the adjustment difficulty is reduced.
As shown in fig. 2, an adjusting device 3 capable of achieving the above synchronous adjustment is provided, which includes gears 31 corresponding to the diversion structures 1 one by one and fixedly arranged relatively, and axes of the gears 31 coincide with the set axis 2; the flow guide structure further comprises a rack 32, the rack moves along the first linear direction A in the set plane and is meshed with the gears 31, and the gears 31 synchronously rotate through adjusting the position of the rack 32, so that the flow guide structures 1 are driven to synchronously rotate. Of course, the above embodiment is only a specific embodiment, and other structures capable of achieving the above technical objects are also within the scope of the present invention.
In the process of pre-oxidizing the precursor, in order to improve the production efficiency, the precursor often enters the oxidation cavity in a multi-layer distribution manner, so that correspondingly, the rotation-adjusting-type gas distribution device in the present invention also has multiple layers to match the number of layers of the precursor, and the synchronization can be realized not only for a single layer in the above embodiment, but also for multiple layers as shown in fig. 3, and in the above embodiment, when each rack 32 realizes the linear motion of synchronization through linkage, the synchronous rotation of all the flow guiding structures 1 in the multi-layer distribution device can be realized.
Alternatively, as another optimization, the adjusting device 3 transmits several sets of power to each flow guiding structure 1. As shown in fig. 4 and 5, a specific way of independently inputting power to the air guiding structure 1 is shown, in this way, the adjusting device 3 includes a plurality of force applying portions 33 which are arranged in one-to-one correspondence with the set axis 2, and the rotation of the air guiding structure 1 around the set axis 2 can be realized by the rotation of the force applying portions 33; similarly, the above embodiment is merely a specific embodiment, and other structures capable of achieving the above technical objects are also within the scope of the present invention.

Similarly, when performing the simultaneous pre-oxidation of multiple layers of precursor, the force application portion 33 in the present invention can synchronously perform the synchronous angle adjustment of the corresponding flow guiding structures 1 in multiple layers, as shown in fig. 6, only needs to establish the relative fixation of the rotating shaft 12 of the corresponding flow guiding structure 1 in multiple layers.
In the above specific embodiment, no matter the rack 32 or the force application part 33 is used, a corresponding fixing structure needs to be arranged in the adjusting device 3 to fix the position after the adjustment is completed, in the process of using the uniform distribution device, the adjusting device 3 is preferably arranged outside a chamber for installing the flow guide structure 1, and the chamber is formed by enclosing a shell structure, so as to avoid the influence on the air flow circulation, and for the fixing structure, the installation can be realized on the shell structure, so as to obtain the position corresponding to the rack 32 or the force application part 33, and the like, so as to realize any fixing mode such as clamping fixing, bolt fixing, clamping fixing, and the like.
The mode of each water conservancy diversion structure 1 simultaneous movement or independent motion above can be selected according to different gas distributor, and when the gas distribution effect that gas distributor realized is more excellent, more be fit for adopting the implementation mode of the simultaneous movement of being convenient for control more, and when gas distributor is limited to the evenly distributed effect of air current, be fit for more adopting the independent control mode that can carry out independent compensation to different positions to further promote the homogeneity behind the gaseous entering oxidation chamber.
