Description

TECHNICAL FIELD

[0001] The utility model belongs to air flotation machine pipeline filter technical field especially relates to a kind of air flotation machine backflow pipeline filter. BACKGROUND

When the traditional air flotation machine backflow pipeline filter is applied, the Y-type filter is used for the pipeline filter, and when it is installed on the horizontal pipeline, it is usually side-mounted, that is, the filter screen part is at the same horizontal plane as the pipeline. If the Y-type filter screen part is below the pipeline, water will accumulate in the Y-type part, causing water hammer and vibration. When installing the Y-type filter, the installer needs to hold it to calibrate the installation position and fix it, which is time-consuming and labor-intensive for the installer.

[0005] 2. When most air flotation machine backflow pipeline filters are applied, the Y-type filter needs to be disassembled after the equipment is shut down for a long time to clean or replace the filter screen inside the filter pipe. There is always some residual water in the filter pipe, which will carry the impurities filtered by the filter screen and flow directly to the ground when disassembled, causing pollution to the ground.
