Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The embodiment of the utility model provides a realize like this, be used for dense sediment device that dense medium deposits as shown in figure 1, include:

a reaction tank 1;

the flocculation tank 2 is connected with the reaction tank 1;

the sedimentation tank 3 is connected with the flocculation tank 2;

and the medium recoverer 5 is connected with the sedimentation tank 3 through a medium circulating pump 4, and the medium recoverer 5 is connected with the reaction tank 1 and used for recovering and treating the medium in the sedimentation tank 3 and sending the treated liquid back to the reaction tank 1.

In practical application, sewage firstly enters the reaction tank 1, a water inlet pipe 6 is installed on one side of the reaction tank 1, a flocculating agent adding pipe is installed on the water inlet pipe 6, namely, sewage is added from the water inlet pipe 6, then, a flocculating agent is added from the flocculating agent adding pipe, so that the sewage is subjected to reaction and flocculation, and in order to improve the reaction effect, a first stirrer 8 is installed in the reaction tank 1, so that flocculation and precipitation are easier to realize under the stirring of the first stirrer 8; the treated sewage enters a flocculation tank 2 for further flocculation, in order to improve flocculation effect, a second stirrer 9 is installed in the flocculation tank 2, namely, the sewage is stirred and flocculated by the second stirrer 9, a flocculating agent can be added according to needs during actual production, the sewage enters a sedimentation tank 3 for sedimentation treatment after flocculation treatment, in order to ensure treatment effect, a third stirrer 10 is installed in the sedimentation tank 3, further, an inclined plate 11 which is obliquely arranged is installed in the sedimentation tank 3, the inclined plate 11 is provided with a plurality of inclined plates 11, the inclined plates 11 are uniformly distributed in the sedimentation tank 3, and particularly, the inclined plate 11 is arranged at the upper part of the sedimentation tank 3, so that flocs above the sedimentation tank can be settled better; the sediment mixed liquid of lower part sends into medium recoverer 5 through medium circulating pump 4 and carries out recovery processing, and the liquid of handling out sends back reaction tank 1 and handles again, and the mud of handling out is then discharged and carries out subsequent processing to realized continuous sewage sedimentation and handled, high-efficient practical more.
