The specific implementation mode is as follows:

the invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.

The intelligent gravity decanter shown in fig. 1 comprises two transverse brackets 1, a decanting weir 2, a first connecting pipe 3, a hose 4, a hoop 5, a second connecting pipe 6, a buoyancy tank 7 and two longitudinal guide rods 8; the two transverse brackets 1 are arranged on the wall body one above the other, the two longitudinal guide rods 8 are fixed on the two transverse brackets 1 one at the left and one at the right, and sliding grooves are formed in the two longitudinal guide rods 8; the water decanting weir 2 is in a cuboid groove shape, floating boxes 7 are arranged on the front side and the rear side, pulleys are arranged on the left end and the right end, and the pulleys are arranged in the guide rails on the two longitudinal guide rods 8; the left end and the right end of the water decanting weir 2 are symmetrically provided with straight double weir mouths, and the center of the lower bottom surface is provided with a water outlet which is matched with the first connecting pipe 3; the first connecting pipe 3 is a tapered pipeline with a wide upper part and a narrow lower part; a water outlet is formed in the wall body and is connected with the second connecting pipe 6 in a matched mode; the upper end of the hose 4 is connected with the first connecting pipe 3 in a matching way, and the lower end of the hose is connected with the second connecting pipe 6 in a matching way.

The intelligent gravity decanter of the utility model is an unpowered decanter, and works according to the principle that the relation between the self gravity and the buoyancy is changed. The utility model discloses a 2 bilateral symmetry of weir of decanting dispose straight two weirs, adopt less weir mouth load to improve and strain the water quality, two weir mouth load superposes can obtain higher efficiency of straining. When the decanting is not finished completely, the water and gas mixture enters the water discharge hose, if the water discharge hose 4 is longer, the water can quickly float out of the water surface, and part of water can stay in the bent pipeline at the lower part of the decanting weir and block the pipeline, so that the water discharge can not be carried out, therefore, the first connecting pipe 3 at the lower part of the decanting weir is made into a cone shape to improve the water flow speed and increase the smoothness of water discharge. The length of the hose 4 should be dimensioned during installation to ensure that the water discharge of the buoyancy tank 7 is not affected when it is at its lowest point.

Preferably, the lower part of the water decanting weir 2 can be additionally provided with a balance weight, so that the water level difference between the inside and the outside of the water decanting weir is increased, the water injection speed is increased, the water injection time is shortened, and the running stability of the water decanter is improved.

hose

4 and 6 of second connecting pipe, prevents that it from taking place to drop.

Preferably, the weir crest levelness error on the decanting weir 2 should be less than 10mm, and when the weir crest levelness error is too large, because the inclination angle becomes large, the water flow has certain acceleration when entering the weir crest, resulting in the increase of the water flow speed, the decanting process is not stable, and the impurities in the sewage are driven to move into the decanting weir 2.

Preferably, the two transverse supports 1 are installed on the wall body through expansion bolts, and the expansion bolts are clamped in the wall body after entering the wall body, so that the stability of the supports 1 is improved.

In the working process of the water decanting weir 2, the water decanting weir 2 descends at the highest point due to self gravity, the pulley rolls in the chute, after the water decanting weir enters water, sewage at the upper part of the sewage treatment tank slowly enters the water decanting weir 2 through the left and right straight water decanting weir mouths, when the buoyancy force borne by the water decanting weir 2 is larger than the self gravity, the water decanting weir 2 starts to ascend, and when the height of the bottom of the water decanting weir 2 is higher than that of the second connecting pipe 6, the sewage in the water decanting weir 2 is discharged through the first connecting pipe 3, the hose 4 and the second connecting pipe 6. When the sewage in the water decanting weir 2 is discharged, the gravity of the water decanting weir is larger than the buoyancy, the water decanting weir moves downwards, and one working cycle is completed.

The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
