Description

Technical Field

[0001] The utility model relates to a centrifugal device for producing and processing hafnium esters, belonging to the technical field of hafnium ester production. Background Art

[0002] Hafnium esters are ultra-high temperature ceramic precursors and key basic raw materials for the preparation of ultra-high temperature ceramic-based composite materials. After years of development, their preparation technology has become increasingly mature, and their comprehensive performance has shown obvious advantages. They have been used in the aerospace field. There are many types of hafnium esters. At present, the production process methods and equipment used for various hafnium esters are also different. Among them, centrifugal devices are needed to assist in the extraction and production of hafnium esters.

[0003] However, the existing hafnium ester production process methods and equipment all adopt intermittent kettle production process technology, which first uses heat transfer inside the reactor to distill the hafnium ester material. However, direct distillation will make it difficult to separate the hafnium ester product from the solvent and by-products, and the efficiency is low. In addition, a large amount of three wastes are generated during the production process, which has a great harm to the environment and has brought certain adverse effects on actual use. Therefore, improvements are needed. Utility Model Content

At the same time, the operation of the centrifugal drive 2 can drive the outer screen frame 4 to rotate, and the outer screen frame 4, the inner screen frame 7 and the stirring frame 11 can rotate in different directions, and The inner screen frame 7 in the active state can perform shock-absorbing activities in the outer screen frame 4 with the help of the shock absorber 5.

The hafnium ester solution after centrifugal treatment will flow to the discharge pipe 14 under the guidance of the smooth protective cover 3 and the guide plate 15, and then the discharge is controlled by the electric control valve on the discharge pipe 14. When it is necessary to clean the outer screen frame 4 and the inner screen frame 7 in the anti-corrosion centrifugal reactor 1, after unlocking the electromagnetic locking relationship of the magnetic positioning plate 16, the upper pulling frame 13 and the upper sealing plate 17 can be controlled to move through the external driving end, thereby exposing the interior of the anti-corrosion centrifugal reactor 1 for cleaning work, thereby ensuring the multi-directional centrifugal screening operation in the production process of hafnium ester.
