Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, the utility model discloses a weak rotational flow vertical air floatation tank, wherein the air floatation tank is a vertical cylindrical sealed tank body 1, and a sewage inlet 2 is positioned in the middle of the tank body 1 and is a tangential inlet; a bubble water inlet 6 is arranged at the lower part of the tank body 1 and is used for providing micro bubbles into the tank body 1, and a purified water outlet 7 is arranged below the bubble water inlet 6; an overflow groove 4 communicated with a sewage drain port 3 is arranged at the upper part of the tank body 1, and an exhaust port 11 and a floating ball level gauge 5 are arranged at the top of the tank body 1; the floating ball level gauge 5 is connected with a purified water control valve (the purified water control valve is not shown in the figure) which is arranged at the purified water outlet 7.
The exhaust port 11 is configured to exhaust outwards to ensure that the tank is in a normal pressure state, and an exhaust device (the exhaust device is not shown in the figure) is connected to the outside of the exhaust port 11, so that a common venturi jet device or an air pump can be configured to form the exhaust device by selecting a pressure monitoring instrument, and the pressure state in the tank is controlled according to pressure detection data in the tank.
According to the utility model, the air floatation tank is of the vertical cylindrical sealing tank body structure, and the sealing structure enables the inside of the tank body to be kept in a normal pressure state, so that normal floating and decontamination work of bubbles is ensured, and floating greasy dirt can be thoroughly removed. And sewage inlet 2 sets up to tangential entry, combines the 1 structure of vertical jar body for come liquid sewage and get into jar body 1 after, downwards spiral rotation in jar body 1 can form weak whirl flow, has increased the flow route of oil drop, thereby has increased the come-up time of compound oil drop bubble, can improve the scrubbing effect.
The can 1 is preferably of cylindrical configuration perpendicular to the horizontal plane, since it is easier to seal and the sealing effect is better.
