Technical Field
[0001] The utility model relates to a polymer stock solution degassing and distributing disk, belonging to the technical field of polymer stock solution degassing and distributing disks. Background Art
[0002] In the industrial production of polyacrylonitrile-based carbon fiber dry-jet wet-spinning precursor, the degassing tower is an indispensable equipment. In actual production, the polymer stock solution is heated and first passes through the degassing tower before entering the storage tank. The stock solution will be distributed, film-falling, degassed, and evaporated in the tower to achieve the appropriate solid content and other technical parameters.
[0003] The degassing tower consists of a motor reducer drive, a coupling, a baffle, a distribution plate, a distribution fan blade, a rotating shaft, a bearing, and a head. The distribution plate and the tower wall require a high-precision gap size, generally 4-5mm. At the same time, in order to improve production efficiency, the equipment needs to run for a long time in normal production, and there is glue on the fan blade surface. After glue is applied, the uniformity between the gaps cannot be guaranteed. In addition, after long-term use, the input current of the glue-applying equipment increases, resulting in unexpected shutdown. The commonly used distribution plates are diverse, but there are problems with long-term operation. This method not only has a very short running time and low efficiency, but also has high labor costs and a low safety factor. It is very unfavorable for efficient production in actual industrial production.
[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] The surface of the distribution fan blade is provided with a non-stick coating, so that the stock liquid can be better distributed to the inner wall of the device.
[0009] Furthermore, the fixing assembly includes a fixed inner ring arranged inside the fixed outer ring, and a reinforcing rib is connected between the inner wall of the fixed inner ring and the outer wall of the fixed outer ring.
[0010] Furthermore, the fixed inner ring and the fixed outer ring are coaxially arranged, and the reinforcing ribs are arranged at equal intervals in the annular gap between the fixed inner ring and the fixed outer ring.
[0011] Furthermore, the reinforcing rib plate is arranged coplanar with the axis of the fixed inner ring.
[0012] Furthermore, the fixing assembly also includes a mounting flange arranged on the inner side of the fixed inner ring, the inner hole of the mounting flange is transitionally matched with the rotating shaft in the degassing tower, and the mounting flange is provided with a plurality of bolt holes.
[0013] Furthermore, the non-stick coating on the surface of the distribution fan blade is Teflon coating.
