KBb type variable micropore aerator
In the process of aeration, the variable micropores on the air distributor can expand by themselves under the action of gas, and the micropores can be opened to ensure the gas passing through the micropores. In the static state, the variable micropores on the air distributor are closed. Due to the self expansion and contraction of the variable micropores, the micropores of the previous aerator are prevented from being blocked. Secondly, an air valve device is set on the chassis of the aerator to prevent the mixed liquid from entering the air distribution branch when the gas supply of the pipeline system is stopped. In this way, the branch pipe can be prevented from being blocked, and the air entering does not need special filtration, and the intermittent aeration is not blocked.
