Before filling the molecular sieve, it is necessary to check that there is no leakage of the molecular sieve in the sieve bed, otherwise it needs to be dealt with. There should be no oil or other debris inside the tank; Personnel participating in filling should not wear work shoes with nails to avoid damaging the sieve bed; Wear clean and oil-free work clothes. Several standard height marks need to be made in the middle part. First, check the ring chamber and fill it with aluminum glue to reach the standard height, then fill it with molecular sieve. Due to the large amount of molecular sieves used, there are generally some differences in the molecular sieves produced by different kilns. Therefore, it is necessary to evenly fill the molecular sieves of the same batch of kilns into two molecular sieve tanks.
After the filling is completed, first use a leveling mechanism to level the molecular sieve and check if it reaches the standard height (the annular chamber has been buried below the molecular sieve). Repeat the leveling work on the molecular sieve until the molecular sieve on the sieve bed is flat and there are no unevenness issues. After checking that there are no issues, it can be considered that the filling work is completed.
