Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated sewage treatment device. Background Art

[0002] In the traditional sewage treatment process, the steps are usually adding medicine-stirring-sedimentation-sludge discharge, so as to filter the clarified liquid from the sewage preliminarily to achieve the purpose of water purification. The defects of the existing sewage treatment process are: the existing sewage treatment equipment uses a dedicated stirring tank, sedimentation tank and sludge discharge equipment for the four processes, resulting in a large footprint of the sewage treatment equipment and a less compact structure; at the same time, since the sewage treatment equipment needs to operate uninterruptedly for a long time, the mechanical drive form of the motor-driven stirring shaft has a relatively high energy consumption. Utility Model Content

[0003] In response to the shortcomings of the above-mentioned prior art, the present application provides an integrated sewage treatment equipment, which uses pneumatic stirring instead of mechanical stirring, has lower energy consumption, and integrates the four-in-one functions of dosing-stirring-sedimentation-sludge discharge in the equipment casing, significantly reducing the footprint and making the structure more compact.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0005] An integrated sewage treatment device comprises an equipment shell, wherein a central cylinder is arranged at the inner center of the equipment shell, a pneumatic stirring component is arranged from the outside of the equipment shell to the inside of the central cylinder, a liquid inlet component is arranged from the outside of the equipment shell to the inside of the central cylinder, and a mud discharge component is arranged from the bottom of the equipment shell to the outside.

[0006] Furthermore, the pneumatic stirring assembly includes a stirring air pipe connected from the outside to the inside of the central tube, and a pneumatic stirring port is detachably provided at the end of the stirring air pipe.

[0007] Furthermore, the liquid inlet assembly includes a three-way pipe arranged above the central tube, two inlets of the three-way pipe are respectively connected to a water inlet pipe and a drug adding pipe, and an outlet of the three-way pipe is connected to the interior of the central tube.

[0008] Furthermore, the mud discharge assembly includes a mud discharge pump disposed at the bottom of the equipment housing, and the outer discharge end of the mud discharge pump is connected to a mud discharge pipe.

[0009] Furthermore, a reflective plate is provided below the central tube, and the reflective plate is in an inwardly convex shape.

[0010] Furthermore, an annular water outlet weir is provided on the upper portion of the equipment housing.

[0011] The beneficial effects of the utility model are as follows:

[0012] Compared with the prior art, the drug addition and water intake of the integrated sewage treatment equipment provided by the utility model are mainly carried out in a relatively closed central cylinder. The drugs and sewage can be pneumatically stirred in a small space to activate, convect and diffuse the mixed liquid, thereby maximizing the drug effect.

[0013] The utility model integrates the adding of chemicals, stirring, settling and sludge discharge into one device, which significantly reduces the floor space of sewage treatment structures, can save land and cope with some situations where space is insufficient.

[0014] The utility model replaces the traditional air holes with a pneumatic stirring port connected with a stirring air pipe. Compared with mechanical stirring, pneumatic stirring has low energy consumption. The pneumatic stirring port of the equipment adopts a rotating airflow to achieve an effect similar to turbine stirring. Not only is the energy consumption low, but the stirring effect is also good. The rotating airflow can also flush the stirring head to prevent flocculation sludge from depositing. Once the air holes of traditional pneumatic stirring equipment are blocked, it is difficult to clean. The stirring air pipe and pneumatic stirring port of the equipment are both detachable, and the pneumatic stirring port can be cleaned and recycled, which is convenient and fast and saves maintenance costs.

[0019] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0020] The utility model provides an integrated sewage treatment device, aiming to solve the problem that traditional sewage treatment equipment occupies a large area and has an insufficiently compact structure, as well as the problem that traditional mechanical drive forms have high energy consumption.

[0021] like Figures 1 to 3As shown, the utility model includes an equipment shell 1, a center tube 2 is arranged at the inner center of the equipment shell 1, a pneumatic stirring component 3 is arranged from the outside of the equipment shell 1 to the inside of the center tube 2, a liquid inlet component 4 is also arranged from the outside of the equipment shell 1 to the inside of the center tube 2, and a mud discharge component 5 is also arranged from the bottom of the equipment shell 1 to the outside.

[0022] In some embodiments, the pneumatic stirring assembly 3 includes a stirring air pipe 31 connected from the outside to the inside of the central tube 2 , and a pneumatic stirring port 32 is detachably provided at the end of the stirring air pipe 31 .

[0023] Through the above technical solution, compared with mechanical stirring, the utility model adopts pneumatic stirring, which has lower energy consumption. When in use, the external air source flows through the pneumatic stirring port 32 through the stirring air pipe 31, and a rotating airflow is used to achieve an effect similar to turbine stirring. Once the air holes of traditional pneumatic stirring equipment are blocked, it is difficult to clean. The stirring air pipe 31 and the pneumatic stirring port 32 of the device are both detachable, and the pneumatic stirring port 32 can be cleaned and recycled, which is convenient and fast and saves maintenance costs.

[0024] In some embodiments, the liquid inlet assembly 4 includes a tee pipe 41 disposed above the central tube 2 , the two inlets of the tee pipe 41 are respectively connected to a water inlet pipe 42 and a dosing pipe 43 , and the outlet of the tee pipe 41 is connected to the interior of the central tube 2 .

[0025] According to the above technical solution, since sewage and liquid medicine need to be poured into the central tube 2 for stirring and mixing, the two liquids can be pre-mixed by using the three-way pipe 41, thereby improving the activation and stirring effects.

[0026] In some embodiments, the mud discharge assembly 5 includes a mud discharge pump 51 disposed at the bottom of the equipment housing 1 , and a mud discharge pipe 52 is connected to the outer discharge end of the mud discharge pump 51 .

[0027] Through the above technical solution, the flocculated particles can be discharged to the outside of the equipment by the mud discharge pump 51 after sinking, so as to prevent the dead mud from being accumulated for a long time.

[0028] In some embodiments, a reflector plate 6 is further disposed below the central tube 2, and the reflector plate 6 is inwardly convex. An annular water outlet weir 7 is disposed on the upper portion of the device housing 1.

[0029] Through the above technical solution, the sewage mixed with drugs will hit the reflector 6 under the action of gravity. Under the action of the reflector 6, the water flow will change direction and distribute to the surroundings, and evenly distribute in the entire pool, flowing slowly from bottom to top at an ascending flow rate. The clarified supernatant overflows from the outlet weir 7 to achieve a water purification effect.

[0030] The working principle of this utility model:

[0031] When in use, external sewage and liquid medicine are pre-mixed and poured into the central tube 2 through the three-way pipe 41, and the external air source is transported to the pneumatic stirring port 32 through the stirring air pipe 31. Under the action of the rotating airflow, an effect similar to turbine stirring is achieved, so that the sewage mixed with medicines is fully activated, convected, diffused and stirred. Finally, the sewage mixed with medicines will hit the reflecting plate 6 under the action of gravity. Under the action of the reflecting plate 6, the water flow will change direction and distribute to the surroundings, and evenly distribute in the entire pool, flowing slowly from bottom to top at an ascending flow rate. The clarified supernatant overflows from the outlet weir 7, thereby achieving a water purification effect.

[0032] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
