Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-4, the present invention relates to a self-floating decanter, which comprises a float 1, a decanter main pipe 2, a drainage hose 3 and a guide rod 4, wherein the decanter main pipe 2 is disposed below the float 1 and connected to the float 1 via a connecting rod 5, the lower end of the connecting rod 5 is fixedly connected to one end of the decanter main pipe 2, the upper end of the connecting rod 5 is rotatably connected to the corresponding end of the float 1, one end of the drainage hose 3 is communicated to the decanter main pipe 2, the other end of the drainage hose 3 is communicated to a fixed water outlet pipe 6 disposed on the wall of a sewage tank, an automatic valve 14 is disposed on the fixed water outlet pipe 6, the guide rod 4 is vertically fixed in the sewage tank, a first fixing plate 7 and a second fixing plate 8 are slidably disposed on the guide rod 4, a motor 9 is disposed on the first fixing plate 7, the power output end of the motor 9 is in transmission connection with the other end of the float 1, the other end of the second fixing plate 8 is fixedly connected with the other end of the main decanting pipe 2, the main decanting pipe 2 slides up and down relative to the guide rod 4, a plurality of water inlets 10 are formed in the side wall of the main decanting pipe 2 along the length direction, and a baffle 11 for shielding the water inlets 10 of the main decanting pipe 2 is arranged on the float 1. When new sewage enters the tank, the float 1 is rotated to enable the baffle 11 to shield the water inlet 10 on the main decanting pipe 2, so that impurities in the sewage are prevented from entering the main decanting pipe 2, after the sewage in the sewage tank is reacted and precipitated, the motor 9 is started, the float 1 is rotated to open the baffle 11, the baffle 11 is rotated for a certain angle, so that the lower end of the baffle 11 is positioned below the liquid level, scum can be blocked, the automatic valve 14 is opened to enable supernatant to be discharged from the main decanting pipe 2, when the main decanting pipe 2 descends to be close to a sludge layer, the automatic valve 14 is closed, and then the float 1 is rotated to seal the water inlet 10 by the baffle 11, so that sludge is prevented from entering the main decanting pipe 2.

Further, the both ends tip center of flotation pontoon 1 is provided with pivot 12, connecting rod 5 through the bearing with the pivot 12 of flotation pontoon 1 one end rotates and is connected, the power take off of motor 9 is connected with the pivot 12 transmission of the flotation pontoon 1 other end.
