Description

Technical Field

[0001] The utility model relates to the technical field of airflow separators, in particular to a novel screen assembly structure of an airflow separator. Background Art

[0002] As we all know, in the existing field of airflow separators, the design of the screen assembly structure is directly related to the screening efficiency and screening accuracy. However, the traditional screen assembly structure often faces some challenges during use, especially the problem that the screen plate is easy to loosen and inconvenient to replace.

[0003] First, since the sieve plate needs to withstand the impact and vibration of the material during the screening process, the fixing method of the sieve plate is not stable enough, which can easily cause the sieve plate to loosen, thereby affecting the screening effect and may even cause damage to the sieve plate. Secondly, during the use of the airflow separator, the sieve plate may need to be replaced due to wear or blockage. The traditional sieve plate structure design is complex, and the process of disassembling and installing the sieve plate is cumbersome, which not only affects production efficiency, but also increases the labor intensity of operators.
