[0013] Preferably, the nominal diameter of the floor drain body is DN100.

[0014] By adopting the above technical solution and setting a floor drain main body, the specification of the floor drain main body is a nominal diameter of DN100, which is suitable for a larger drainage volume.

[0015] Preferably, the floor drain body, sedimentation box, cover and supporting feet are all made of CF-8M stainless steel.

[0016] By adopting the above technical solution, the CF-8M stainless steel material is set, which has the advantages of good corrosion resistance, good welding performance, strong plasticity, high temperature resistance, etc.

[0017] Preferably, the plurality of water outlets include a large water outlet and a small water outlet, the large water outlet is located on a side of the sedimentation box facing away from the floor drain body, and the small water outlet is located on a side of the sedimentation box facing the floor drain body.

[0018] Preferably, several of the water outlets further include flexible inclined surfaces distributed on the inner wall of the water outlet, one end of the flexible inclined surface is fixed on the inner wall of the water outlet, and the other end is inclined toward the small water outlet.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] By setting up a sedimentation tank, after the floor drain main body is installed at the nuclear wastewater discharge pipe outlet, the nuclear waste water flows into the floor drain main body and then enters the sedimentation tank. The residues in the nuclear waste water are precipitated in the sedimentation tank, and the waste water flows out from the outlet, preventing the floor drain main body from being blocked by the residues.

[0021] By arranging the supporting feet, when the sedimentation box is placed in the floor drain body, the supporting feet can be used to suspend the sedimentation box above the water outlet pipe hole of the floor drain body, so as to facilitate the flow of sewage.
