The box 210 and the liner 220 may be integrally formed, and the first assembly 100 may close an opening of the box 210, so that an inner cavity of the box 210 forms a closed accommodating cavity. When the inside of the accommodating cavity needs to be dredged for maintenance or the inner wall of the accommodating cavity needs to be subjected to corrosion prevention treatment, the first assembly 100 and the lining plate 220 can be detached and separated, so that the inner cavity of the box body 210 can be maintained and repaired.

As shown in fig. 1, the tank 210 has an opening in its inner cavity, the liner 220 is connected to the tank 210 around the opening, and the first assembly 100 covers the opening. A gasket is provided between the first assembly 100 and the liner 220 to ensure the sealing of the joint between the first assembly 100 and the second assembly 200. The first assembly 100 is detachably coupled by fastening or bolting the liner plate 220.

The thickness of the anticorrosive layer can be set to 320 micrometers, 350 micrometers, 400 micrometers or 450 micrometers, and the anticorrosive layer is prevented from being corroded due to sewage washing by thickening the anticorrosive layer. In addition, the problem of falling off of the anticorrosive layer is easily caused by the overlarge thickness of the anticorrosive layer, and the production cost is not favorably reduced, so that the thickness of the anticorrosive layer is preferably controlled to be 300-330 microns.

Furthermore, the anti-corrosion layer is made of a fiber reinforced composite material or a rubber layer film. The film formed by the fiber reinforced composite material or the rubber material has stronger corrosion resistance, and the service life of the air floatation water distribution device can be further prolonged.

Furthermore, the anticorrosive coating has insulativity and can withstand voltage with the strength of 3000V-10000V, so that electrochemical reaction with ions in sewage is avoided, and the corrosion resistance is further improved.
