As shown in fig. 15, the difference between this embodiment and embodiment 1 is that the relative position of the vertical pipe connecting pipe 40 and the waste water discharging port 13 is changed, the water sealing mechanism is a U-shaped water sealing elbow 25, the inlet of the U-shaped water sealing elbow 25 is correspondingly connected to the waste water discharging port 13, and the outlet of the U-shaped water sealing elbow 25 is not lower than the lowest part of the U-shaped water sealing elbow.
The water seal elbow 25 can be a U-shaped water seal elbow, an S-shaped water seal elbow or other shapes of water seal elbows in the prior art. The waste water drainage pipe 14 in this embodiment is a cap-cylinder structure, and a plurality of inlet pipes 17 are arranged on the waste water drainage pipe 14, and the inlet pipes 17 are used for matching with different waste water discharge sources, such as a surface pool, a floor drain and the like, and when the U-shaped water seal elbow needs to be overhauled, the waste water drainage pipe 14 can be pulled out from the waste water discharge port 13.
The installation method of this embodiment is the same as that of embodiment 4.
The modularized same-floor drainage device for the high-rise building has the technical characteristic that the lowest position of a water outlet of a water seal mechanism is not lower than the lowest position of a water outlet of a vertical pipe connecting pipe, otherwise, smooth drainage cannot be realized.
In the modular same-floor drainage device for high floors described in embodiments 1 to 12, when in use, the drainage port of the toilet bowl and the vertical drainage pipe are communicated by the sewage side drainage connecting piece, which is a box-type structure, so that sewage can be effectively contained and discharged from the opening of the side wall (i.e. the sewage outlet 32) into the vertical pipe connecting pipe 40, and then enters the vertical drainage pipe, without causing blockage, and the sewage discharge capacity can be adjusted by adjusting the area of the communication port between the sewage outlet 32 and the vertical pipe connecting pipe 40; the toilet bowl water outlet is inserted in alignment with the eccentric jack 33, when the rotary plug-in 34 is matched with the toilet bowl connecting port 31, the corresponding positions of the jack 33 and the toilet bowl connecting port 31 can be adjusted according to requirements, the change allowance of the installation space is reserved, and the installation is convenient;
the present embodiment implies a feature that the toilet connection port of the waste tank is located at the end of the waste tank, but is not limited to this structure.
Certainly, the molding of sewage case has the structure at certain inclination or sewage case and riser connecting pipe are certain installation contained angle, are favorable to sewage to flow into in the riser connecting pipe more, and this technical characteristic is also in this application technical scheme's the scope of including.
Meanwhile, the waste water in the drainage outlets such as floor drains, bathtubs, wash basins, mop pools and the like in the toilet is directly gathered into the waste water drainage pipe 14, is drained into the water gathering tank 10 after passing through a water sealing mechanism, then flows to the water outlet 41 of the vertical pipe connecting piece 40, and is drained into the drainage vertical pipe from the water outlet. The water sealing mechanism can effectively block odor which is turned over and gushes in the vertical drainage pipe and the water collecting tank 1.
The waste water drain pipe 14 is directly connected with the water seal box in the water collecting box 10, so that a structure for concentrating water seal and deodorization is formed, a plurality of water seal designs in the prior art are replaced, and the problem of indoor odor return caused by failure of a certain water seal is avoided.
Liquid, solid and gas in the drainage vertical pipe are converged to form sewage flow, liquid, solid and gas are separated in the water collecting tank 10 of each floor, gas in the drainage vertical pipe and the water collecting tank 10 is directly discharged into the upper vent pipe 70 from a gas flow channel between the lower vent pipe 71 and the upper vent pipe insertion hole 70, water and gas separation layer by layer is achieved, air pressure fluctuation in the drainage vertical pipe and the water collecting tank 10 is reduced, a water sealing mechanism is prevented from being damaged by air pressure impact, and indoor air environment is prevented from being polluted by returning odor of a drainage system.
The design of the flanging 12 of the header 11 forms a lap joint mechanism of flat joint → downward turnover with the waterproof layer 51 of the toilet, so that the waterproof layer 51 can effectively cover the installation gap between the header and the floor slab installation hole without adopting concrete for filling; meanwhile, the end part of the waterproof layer 51 is positioned on the header top cover 11, and the height difference is formed between the waterproof layer and the waterproof layer on the ground, so that the ground accumulated water can flow onto the header top cover 11 in a guiding manner and is discharged into the header 10, and the accumulated water cannot flow backwards from the bonding seam between the waterproof layer 51 and the header top cover 11, thereby thoroughly solving the problem of accumulated water leakage at the position where a pipeline passes through a floor slab in the prior art.
It should be particularly noted that it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, such as: the specific connection position of the water seal tank and the header of the catchment tank and the shape of the water seal tank, the water seal tank adopts a water seal cylinder, a water seal bent pipe, a partition plate or other water seal components in the prior art, the shape of the sewage tank, the cross-sectional structure and the area of a sewage outlet, the arrangement position of a toilet bowl connector on the sewage tank, the position distribution of a water drainage hole on the header and other technical characteristics. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the drawings shall not be construed as limiting the claim concerned.
